The adoption of methodologies and practices from distance learning (MOOC) and gamification is a promising basis to facilitate the design of a new generation of MOOCs (massive online open courses) and well suited for XR-based immersive shared social spaces, i.e., educational metaverses. Therefore, we discuss the tools and requirements to assist teachers to acquire two levels of competence, “beginner-level creator” and “advanced-level creator”, within the current ecosystem of metaverses. The adoption of such tools and XR platforms within STEM university educational settings is discussed to introduce the novel concept of the edu-metaverse. Full article

The service industry depends on Internet development that always changes. The changing service environment provides a range of opportunities to develop new information technology to communicate with customers and add new channels to reach all service providers. Hospital administration pays attention to improving medical service quality and using information systems for clinical care. A nursing information system is the most important part of the whole medical care information system. The aim of this study is to explore the key factors of user interface (UI) and the function of the emergency department information system (EDIS) from the viewpoint of the user’s operation. The questionnaire design is based on literature reviews and invited academic and industry scholars to conduct a pre-test for the validity of the content. The staff of a regional teaching hospital in central Taiwan were taken as the research subjects The study was based on the information system success model proposed by DeLong and McLean in 2003. In order to understand the use of information systems in hospitals, the TAM (technology acceptance model) is used to investigate the factors that influence the acceptance of new technology. A survey was conducted on the employees who are using the EDIS at present. There are four categories of participants: attending physicians, nurses, specialist nurses, and secretaries/registers. The results indicate that “user satisfaction” affects the success of the EDIS. For the question, “emergency medical information system has more benefits than traditional paper”, respondents gave good marks. For the question, “the stability of the emergency medical information system is very satisfactory“ was given the lowest. The aspects of the information system success model for the terms “system quality”, “information quality”, “service quality”, etc. were analyzed. User satisfaction is positively related, although user education is different. The reference data allow hospital administrators to consider the needs of users while developing or conversing about new systems for the future. Full article

Most schools do not have a large insurance database or OLAP platform for students’ learning, operating, and communication. The university courses investigated in this research were insurance information system courses. Those courses were conducted in a project-based learning approach and mutual communication networking. To facilitate the student’s practice, these courses were divided into several groups to create an Excel micro-database and OLAP simulation analysis with pivot analysis charts was executed. In these courses, students needed to overcome the challenge of software operation. After being taught by teachers or classmates, all students were able to complete the designated project reports in those courses. A questionnaire survey result showed that students’ course satisfaction was higher than average. The flexibility for students to choose the topic of projects is the key success indicator. Additionally, integrating group and individual communication networking was also important to enhance students’ performance. Full article

Lots of Insurance companies have constructed databases for ad hoc query software in Taiwan that combines customer relationship management and marketing campaign management. An ad hoc query is a non-routine and specific query performed in real time to filter specific customer information from big data. Ad hoc query has the strength to retrieve customer information more quickly and conveniently than by filtering target customer lists using a mainframe or OLAP. In this study, the strengths and weaknesses of ad hoc query, online analytical processing (OLAP), and general query using a mainframe are analyzed. The results indicate that ad hoc query has the advantage of flexibility for users’ specific needs. Ad hoc query has obstacles and challenges for users regarding how to learn its system fields and writing programs. It is concluded that the design between individual assured suggestions and a convenient operation process is critical for raising the response rate. Additionally, precisely filtering technology for target customers is the key success factor for an accident insurance campaign. Full article

Previous crisis communication research has been based on qualitative methods such as interviews or questionnaires, which require considerable manpower, material resources, and time to focus on specific topics. The current situation needs to be reflected timelier. With the rise of social communities, community users’ comments have gradually become an important reference for other community members. Twitter is one of the most popular social media in the world. During the COVID-19 pandemic, people were restricted by rules and government policies, such as wearing masks, maintaining social distancing, and avoiding crowding. This led people to spend time on devices. By using devices, most people are involved in social media activities. This study aims to discover the awareness Indonesians display in the text they upload to Twitter. Using the Twitter crawling technique, we collected data. We also analyzed the text with text mining techniques and latent semantic analysis (LSA) with semiotic methods. The crisis communication was classified, and the definition of crisis terminology was improved in social media. Full article

Over the past few decades, drastic advances in technology have forced insurers to seek transformation in order to survive in a changing environment. Along with the outbreak of COVID-19, online insurance has become a much-needed distribution channel for insurers, not only as a cost-effective option, but also in line with pandemic prevention measures. However, in contrast to insurers’ vast investment in AI, chatbots, etc., online insurance only accounted for less than 2% of the total premium in Taiwan in 2022. This article uses importance-performance analysis (IPA) to identify disparities between client perceptions of crucial elements of online insurance services and their actual performance. The results show that among constructs such as perceived usefulness, ease of use, security, and service quality, customer experience can be greatly enhanced if insurers prioritize improving website security and service quality.

The Feast of Drunken Dragon is a special intangible cultural heritage of Macau, which is also known as the Drunken Dragon and Lion Dance Gala. Every year, on the eighth day of the fourth month of the lunar calendar, members of the Macau Fish Traders Association hold a drunken dragon and lion dance activity at the Macau Sanjie Guild Hall. Festivals play a part in cultural designing. They not only attract a large number of tourists but also promote local culture. The Drunken Dragon Dance is currently encountering many problems such as the inability to introduce new performance methods as technicians are getting older, and young people are unwilling to inherit it. This cultural heritage tends to gradually decline. The Cultural Affairs Bureau of the Macao Government has paid attention to the problem. However, the publicity methods are still mainly based on videos, simple online graphics, and cultural and creative products, and the impact of the COVID-19 epidemic harmed the promotion. With the rapid development of technology, mobile devices provide digital reading and augmented reality (AR) to assist learning. Thus, learning is not limited in space and time, and individuals continue to use it without hindrance. Using the concept of experiential learning, we design interactive teaching materials with dynamic images to advertise the historical stories of the Feast of Drunken Dragon in Macau, folk rituals, and traditional dragon performances through the AR interactive experience of the drunken dragon festival. The concept of learning by doing is an experiential way to understand relevant intangible cultural heritage knowledge. Using digital content, teaching material design is provided based on user experience to achieve sustainable education. Full article

The maturation of gamification techniques and virtual reality technologies has progressed differently. Today, gamification has been consolidated, and virtual reality is becoming a widespread technology. These two are united in the university course of “virtual reality, augmented reality and gamification” as the Msc curriculum in Digital Humanities. This is a STEM course where an original gamification system was studied to teach complex topics with different bachelor backgrounds as engineering, design, communication, and literature studies. This research was conducted starting in the academic year 2016–2017 using TV series to create a sense of engagement during the course. The results of the 6 year teaching of the gamified course were presented in this article with constant feedback from involved students. Full article

Programmatic advertising uses big data to spread personalized marketing materials to target audiences, which is a major driving force for the growth of digital advertising. Among them, in-application advertisements (in-app ads) are an important part of programmatic advertising. In in-app advertising, which is highly related to application revenue, ads are delivered to customers through mobile devices at any time and place based on personal needs. Due to the power of electronic Word-of-Mouth (e-WOM), text comments from social media are becoming a new mode of advertising, influencing consumers’ purchase behavior. Text reviews on social media are more powerful than traditional ads. However, relatively little research has studied this issue. Therefore, using text mining and latent semantic analysis techniques, we aimed to discover the advertising elements of text reviews in the social community. Based on the results, suggestions were made to advertising companies to improve the performance of text reviews when employing key opinion leaders (KOL) to write commercial comments that promote products or services.

Since the establishment of ‘Careers for the Disabled’, China has been committed to promoting the program. Special higher education for the disabled is regarded as important for the protection of the rights of the disabled and for the achievement of equity and promotion of the development of special higher education. Currently, many colleges and universities in China provide higher education for the disabled. However, special higher education has problems such as a lack of capable teachers, which requires active inter-school cooperation. Thus, we propose the construction of an online education community for the disabled to overcome the existing problems and propose a methody of promoting the development of special higher education to a higher standard.

Social media is the main channel that teenagers use to exchange information. The purpose of this study is to construct a prediction model of school social media usage intention. To collect training data for modeling, we conducted a questionnaire survey on students of a senior high school in Taoyuan City, Taiwan. The training data processing method was decision tree computing. In this study, the decision tree computing software, Weka, was used to analyze the training data to extract the key factors affecting high school students’ intentions to use school social media. The research results showed that perceived usefulness was the most important factor affecting school social media usage intentions, and trust was the second most important factor affecting school social media usage intention. The prediction model was proposed in this study to predict students’ intentions to use school social media. It serves as a guide for schools to use social media as a channel for distributing important information. Full article

Recently, information, communication, and technologies (ICTs) and the tourism sector have gained attention from researchers and practitioners. Thus, we examined the trends in using ICTs in the tourism sector using a scientific document approach based on bibliometric analysis. A bibliometric analysis was conducted on 102 selected papers from the Scopus database from 2000 to 2021. The results revealed that the most discussed keywords in the papers were ICT and destination management organization, smart tourism destination, and smart city. Co-occurrence analysis was performed to analyze the trending topic in ICTs, tourism, and hospitality used by academics, while authorship network collaboration examined the partnership between different countries around the world. Statistics such as the number of documents per country, number of citations related to each country, ICT practice studies, and research methods were also discussed in this study. Limitations and implications were also indicated to provide deeper insights to researchers and their future research in terms of ICTs, tourism, and hospitality. Full article

Due to the rapid innovative applications of technological education as a result of the swift development and popularity of telecommunication and wireless technologies, ever-more diversified methods of technological education play a critical role in various education and lecturing activities, without time and distance restrictions. Currently, in order to bridge the urban–rural development gap, the Taiwanese Government has introduced a lot of policies to encourage teenagers to return their hometowns; however, these policies have not achieved their goals, as the most of Taiwanese community development associations faced scarcities of professional knowledge without any educational support during the development of their various schemes, such as economic development, environmental protection, cultural heritage, public services, etc. As a result, local development depends on entire community development associations, especially in the most mountain regions of Taiwan. Moreover, community development associations have a lot of social responsibilities, such as age-related caring activities, driving local economies and industrial development, environmental protection and education, maintaining and developing traditional cultures and arts, etc. Due to the digital characteristics of technological education, most Taiwanese rural community development associations are able to obtain professional information and data about courses without space and time restrictions. Thus, after strengthening and satisfying professionals’ demands, local economies will achieve growth and, therefore, younger persons would be encouraged to stay their original area, thus stimulating the development of rural community development associations. Eventually, the positive development cycle is predicted to increased and, as a result, the urban–rural disparities will be directly diminished by the diversified application of technological education in Taiwan.

Based on the blueprint for bilingual education as a national policy, teachers in technical and vocational schools are preparing, in full swing, to teach subjects in English. However, most teachers in the institutions do not have the skills and backgrounds to implement English-mediated instruction (EMI). Therefore, it is necessary to cultivate talents and popularize programs in technical and vocational education and educate talents to have bilingual ability. In addition, international mobility and internship experience in English is also required. The current environment needs to be improved for bilingual education, promoting that bilingual teaching is beneficial to students and teachers. Even though thus puts pressure on them for learning and teaching in technical and vocational schools, bilingual education is the future direction of education in Taiwan. Full article

One of the tools to use in the ever-increasing implementation of the flipped classroom is the online quiz to monitor students’ formative learning. However, in useful and convenient administering online quizzes, how students engage with them creates a paradox. This case study discusses four main components: the instructor’s reasoning for using online quizzes, two different implementation approaches, how the students behaved whilst completing them, and reflecting on how closely the learning results compared to the original intentions. As a result, ways to keep the students on the intended learning path are proposed to limit divergence. Full article

An investigation and assessment of virtual learning in engineering mathematics during the COVID-19 pandemic were explored in this study. The result showed that the media platform was an especially useful technology for students to create, share, learn, and interact with others. YouTube, a free media-sharing website, has proved to be an effective educational tool to add a new dimension to education in increasing student engagement, motivation, understanding, and achievement. Thus, students’ learning models on the OpenCourseWare YouTube channel were researched to investigate how virtual activities in e-learning of engineering mathematics during coronavirus confinement were implemented and describe how YouTube was used for teaching engineering mathematics by engaging students in mathematical problem-solving.

More artists have come to use computer processing to create works with amazing visual effects. Rik Oostenbroek’s works, his creative style, and methods are studied in this research. Born on 25 May 1989, Rik Oostenbroek is a Netherlands-based illustrator and designer. He focuses on digital art creation. His works are recreated by photography, including dynamic images and graphic design with gorgeous colors and dynamic and fluent lines. Currently living in Hilversum, Rik Oostenbroek is a self-taught Dutch freelance artist, designer, and art director working for many brands such as Apple, Nike, Epson, and Viacom. Known for his dynamic forms and unique abstract shapes, Rik is skilled in various design styles, including graphic design, typography, 3D graphics, art direction, surreal/abstract illustration, and a mixture of photo manipulation and retouching. His pioneering style is mainly based on the various patterns created by computers quickly and accurately, which attracts many imitators to follow. As this type of visual style brings greater commercial benefits and suits the visual collocation of various products, Rik’s style is of research value. By summarizing Rik’s works and comparing them with others, this article demonstrates the creation process and method of his work using computers and illustrates the limitations and challenges arising from those processes. Blender 3.0, a third-party free software, is used in this demonstration. Full article

How to use social media to publicize policies is one of the most critical topics for local governments to operate social networking. Thus, this study is carried out to analyze the relationship between post-presenting and visual design taking the Facebook fan page of the Construction Office of Taitung County Government as an example and using big data technology. The results show that the promotion effect of images and text is higher than that of videos, reposted news, and shared posts. Moreover, the type of image and text is more attention with the position with more than 100 words, and there is no significant difference in the promotion effect of text layout, hashtags, and image forms (graphics or photos). The results of this study provide a reference for future government management of social media, reducing the waste of human resources and ineffective costs. Full article

Taiwan’s birthrate has been declining for nearly a decade, with the newborn population falling from 305,312 in 2000 to 153,820 in 2021. Education has been adversely affected by the low birthrates but also by other industries. Schools must therefore review their brand positioning and develop their brand value. Brand influence, from products to retail stores, from people to organizations, was regarded as the most valuable intangible asset in the past. Schools need to establish brand symbols so that relevant briefings, publicity, stationery, posters, and packaging convey a consistent image of the school. For example, the University of Wisconsin–Madison and the Chaoyang University of Technology have used this method to build a series of brand identities. Of course, the department inherits the brand spirit of the school but is full of its characteristics and positioning. Despite this, few departments establish their brand symbols to achieve consistent brand communication, which is an important research gap in the present study. In this research, the faculty and students of the department were invited to extract the brand knowledge of the Department of Marketing and Logistics Management of Chaoyang University of Science and Technology through the idea of free associations. A total of 7 questionnaires for faculties and 50 questionnaires for students were collected; the questionnaire was composed of five dimensions. As a result, 23 symbols were obtained to represent the Department of Marketing and Logistics Management. The Department of Design’s brand symbols can be used for related cultural product design, event posters, and other applications to create a specific brand association and improve brand equity, brand reputation, and memory. These symbols can also be used in related cultural products, event posters, and other applications. Full article

Using big data analysis, we study the consumer life cycle based on the following four aspects: customer acquisition, participation, profit, and return visit rate. The Google Merchandise store is selected as a case study to collect data during January–December 2022. Thirteen traffic source dimension elements of the four layers were summarized and analyzed, and the following results were obtained. Consumers complete a conversion rate of 57 million. The late contact point affects the conversion rate, which is much higher than that in the early and middle periods. Reducing the number of touchpoints in the conversion increases the revenue. Understanding customers’ shopping habits helps improve advertising results. Thus, website managers need to introduce Google Analytics 4 analytics at different stages for site quality and business effectiveness. Full article

Based on Vickrey’s bottleneck model, we propose an activity-based bottleneck model to study traffic congestion on freeways during holidays. Based on the activity-based bottleneck model, we study the bottleneck ladder charging problem under the linear marginal activity utility and compare it with the traditional bottleneck model. Compared with the activity-based bottleneck model, the traditional bottleneck model overestimates the queue delay at the bottleneck, the level of step charging, and the start and end time of peak hours. Therefore, the activity-based step charging method disperses the traffic pressure on peak sections to a certain extent, avoiding traffic accidents caused by the transition period between charging and free.

Educational videos have become an important part of higher education. Thus, it is necessary to discuss practical tips for creating high-yield educational videos. The electronic medium is integrated into traditional courses and serves as the cornerstone of many blended courses. Multiple studies have demonstrated that video is a highly effective educational tool for learning, particularly for hard-to-visualize processes and procedural education. Video allows learners to view content at their own pace and view on-demand materials repetitively. Video on YouTube can be integrated as a supplement to course content to provide targeted information and enrich the learning environment for students. In this article, creating an effective video on YouTube is introduced, providing examples of effective recording and integrating video into engineering mathematics courses on YouTube. Full article

Many colleges’ graphic design departments have created curriculums related to digital publishing. While digital reading has become popular and various technologies of e-book production are mature, there are urgent demands to strategically and systematically cultivate professionals for the digital content industries. Thus, this research was to examine the problems associated with e-book production and their causes for future curriculum design. A literature review of college teaching courses in design-related departments was conducted, and an analytic hierarchy process (AHP) was applied with twelve senior digital publishing practitioners. The results showed that “interactive setting” was the most common problem. The next most common problems were “color labeling” and “graphic setting”. In-depth interviews with seven experts which were selected from technical and vocational colleges and the digital publishing industry revealed the causes of these problems. The reasons of mistakes were categorized into 54 causes for the seven most common problem categories. Among the causes of “interactive setting” errors, “setting the media playback controller” happened most frequently. Full article

With respect to widely evaluating and elementally assaying the comprehensive possible applications of Internet of Things (IoT) technology for efficiently advancing administrative and operating performances during the implementation of community development missions, this research attempts to initially analyze the various means of employing Internet of Things (IoT) technology by assessing the affairs and activities of 6918 contemporary community associations in Taiwan in order to inductively construct the most effective Internet of Things (IoT) digital system, not only to update their original documentary administrative system to easily and conveniently implement and record administrative missions, activities, and services but also to handle and display the bulk of news and information from most community residents and the Taiwanese government (such as the Council of Agriculture, Executive Yuan). However, after conducting a systematic survey on research related to the Internet of Things (IoT) technology in recent years, there is no one able to directly analyze the shortages and challenges of the diversified applications of Internet of Things (IoT) technology in administrative performance. Specifically, the greatest challenges are the Taiwanese individual information protection regulations and the laws regarding the various applications of digital data (such as the Taiwan Personal Data Protection and Telecommunication Acts), which apparently hinder the development of Internet of Things (IoT) technology in the enhancement of community associations in Taiwan. Therefore, the suggestion contributed by this research is to institute basic digital data using ACT for all 6918 community associations in Taiwan in order to directly force the application of IoT technology to advance the performances and achievements of community development associations.

In life, making a decision is always required. Various situations demanding decision making are encountered in life. We apply the core decisive modes of game theory to closed couple relationships in conflict situations for the following reasons. (1) Life can be explained by the comprehensive decisions in games, as various conflict situations appear in a closed couple relationship. (2) Humans are influenced by diverse factors such as love, sacrifice, intuition, and the benefit of individual personality. (3) Information asymmetry is generated in subjective and objective environments. (4) Human nature is selfish. Based on the results of this research on the three core decisive modes in game theory, there are in-depth considerations and better win-win solutions considering the prisoner’s dilemma. Game theory is further assayed in the further research for “Analyzing the research interfering factors of the core decisive modes of the game theory on the closed couple relationships at the conflict”.

Students’ after-class self-evaluated comments are useful for understanding students’ learning and reflecting teacher’s teaching. Researchers and engineers have attempted to apply educational data mining techniques, such as text analysis, sentiment analysis, machine learning, and deep learning to develop classification mechanisms of students’ self-evaluated comments. This study was carried out to develop aspect and sentiment classification mechanisms to automatically classify students’ self-evaluated comments into seven aspect categories and three sentiment categories. We investigated the impact of whether we should exclude nonsense data or not, the impact of different feature extraction methods, and the impact of different classification models on classification accuracy. The results showed that the combination of bidirectional encoder representations from transformers (BERT) word embedding feature extraction and Random Forest classification showed the best accuracy (90.7%) on aspect classification when including nonsense data, whereas the combination of BERT-word embedding feature extraction and Random Forest classification had the best accuracy (93.2%) on aspect classification when excluding nonsense data. Including nonsense data reduced the classification accuracies. In addition, the combination of one-word bag-of-words feature extraction and Random Forest classification presented the best accuracy (99.5%) with regard to sentiment classification. Full article

The purpose of this study was to explore college students’ purchase behaviors using a multivariate statistical model. Because many college students today have part-time jobs, they have increased opportunities to consume higher-quality brands. In Taiwan, Starbucks is regarded as a high-quality coffee brand, costing more than most local coffee brands. To clarify why such students in Taiwan are willing to pay more for Starbucks, data were collected from a sample of 402 college students. The results showed differences in purchase decisions between students majoring in different disciplines and lifestyles. The findings had theoretical and practical implications especially for the marketing strategy of the Taiwanese coffee industry. Full article

Today, students are accustomed to visual information and need engaging, stimulating, and fun teaching in logic and engineering methods for learning purposes. Traditional presentations and the transfer of memory information cannot arouse students’ interest. By implementing logic and engineering methods in their teaching, teachers strive to promote active learning and deepen the learning effect by motivating students and engendering interest in learning. Problem-based learning (PBL) allows students to clarify or solve problems by identifying gaps in their knowledge, constructing clear educational topics, and integrating relevant information (PBL). This study aims to motivate students to learn through problem-oriented game-based approaches which help to solve chain board game development problems that increase learning efficiency. Third-year students have already mastered the basics of theoretical knowledge and have gained relevant work experience in industry–academy internships, class cadre work, and community service. Learning effectiveness and methods of learning, social interaction, and subject engagement are significantly different, according to an analytical study of SPSS data. The use of methods and the organization of notes are significantly more likely to be observed in students with high learning outcomes than in students with low learning outcomes. Learning outcomes do not differ significantly between students with high and poor peer ratings of board games. Students with high peer ratings of board games perform better than their poor peers in terms of learning methods. Students with poor peer scores in board games have significantly more body input than students with good scores. The results of this study can be helpful to teachers in subsequent curriculum design to improve students’ learning effectiveness. Full article

The purpose of this study was to investigate the relationships between English learning motivation, English leisure activities, and the English learning effect on elementary school children by using a linear regression model. The collected data were analyzed with descriptive statistics, multivariate simultaneous linear regression, and mediation tests. The result showed that elementary students lack parental involvement in English learning. Regular parental support leads to better learning outcomes. English leisure activities are crucial for improving motivation and effectiveness. Schools and parents should prioritize English skills through daily learning and leisure activities to incrementally improve English ability and positively impact learning. Full article

Since the COVID-19 pandemic, synchronous distance learning has become a common teaching method. However, there are problems in synchronous distance learning, such as distractions and cheating. Many studies have shown that gamification has been used as one way to improve student’s learning motivation. Thus, we explored the functional requirements of synchronous distance learning software and different distance learning acceptance with gamification elements by students using KANO and an importance-performance analysis. The results of the study showed that most students thought it important to integrate games into synchronous distance learning, and gamification brought more fun to learning while achieving the purpose of learning.

This study aimed to evaluate tourist characteristics, rental factors, non-rental factors, and use intention of shared motorcycles in tourism activities. Linear regression analysis was used to compare the differences and influences of variables. A convenience sampling survey method was adopted to investigate GoShare motorcycle-sharing service. Questionnaires were distributed to 271 respondents aged 20–29 years old who used motorcycles in tourism. With data descriptive statistics, t-test, one-way analysis of variance, and regression analysis were conducted, and four main results were obtained: (1) The respondents tended to follow a “Freestyle travel” type. (2) As a rental factor, “Environmental Efficiency” was the most important. (3) “Renting is not easy” was the most important reason not to rent a motorcycle. (4) Tourist characteristics and rental factors impacted use intention significantly. Therefore, the following suggestions were made in this study: it is necessary to (1) strengthen the promotion of the GoShare motorcycle-sharing service, (2) enhance the quality of the rental service, (3) improve the mobile application, and (4) focus on in-depth tourism and expand the services at scenic spots.

Patents and related statistics are the indicators of technological progress. There have been controversial discussions about the value of patents as an indicator of technological advancement. Patent research has been conducted for research and development to develop the core framework of the United States Patent and Trademark Office. This study was conducted to classify the patents in terms of technology-assisted instruction using the Patent Co-citation Analysis (PCA) method and factor analysis. For the analysis, education, demonstration, rendition, instructional aids, instructional equipment, teaching aids, and didactic materials were chosen as keywords to construct a citation relationship network of patents and to classify core patent issues. The study results showed that 225 patents were cited more than 25 times. They were classified into 11 categories. The result provided information on the development and application of technology-assisted education to develop teaching tools further. Full article

We investigated the relationship between the personal backgrounds, learning experiences, and learning outcomes of college students serving as student association cadres by applying the indicators of the Council for the Advancement of Standards in Higher Education (CAS) in the United States. The participants of this study were students at the university student associations in Taiwan, and the sampling was carried out through purposeful sampling. We distributed 1850 questionnaires, and 1761 valid questionnaires were received with a recovery rate of 95%. The self-assessed learning outcomes of the student association cadres were good. Among them, “integration and speculation of cognition” was the highest, followed by “integration and application of knowledge”, “inner self-development”, “interpersonal interaction ability”, “practice ability”, and “social care and civic literacy”. The self-assessment of the student association cadres in their learning experience was also positive. Among them, “experience in engagement” was the highest, followed by “experience in management”, “experience in handling activities”, and “experience in training courses”; while “experience in participating in activities” was the lowest. Through a hierarchical linear regression analysis of the American CAS learning outcome indicator, the student association cadres’ personal background and learning experience had significant explanatory power. The R-squared value of each aspect ranged from 39.6% to 61.1%. It was obvious that the American CAS indicator could be used to examine the learning outcomes of higher education student associations in Taiwan. The results confirm that studying student associations could become an essential approach for cultivating students’ learning outcomes and become an essential reference for Taiwan’s universities and colleges to promote community education.

Pairs trading is a popular quantitative trading strategy with the advantage of a similarity in price movement to financial assets. Assuming that the price spreads of trading pairs are mean-reverting, this strategy exploits the disequilibrium in financial markets to find arbitrage investment opportunities. Pairs trading has been widely applied to stock, ETF, and commodity markets. However, the effectiveness of this method for cryptocurrency markets has yet to be properly explored. Therefore, we examine the profitability of pairs trading for 26 cryptocurrencies traded on the Binance exchange at high frequencies of 1, 5, and 60 min. In addition to the traditional statistical methods of distance, correlation, cointegration, and stochastic differential residual (SDR), we focus on two evolutionary algorithms: genetic algorithm (GA) and non-dominated sorting genetic algorithm II (NSGA-II). During the 79-trading-day period from 11 January to 31 March 2018, NSGA-II showed the best results at all frequencies, with an average return of 2.84%. Among the statistical models, SDR ranks first, whereas Correlation ranks last, with average returns of 1.63% and −0.48%, respectively. The z-test results show that the models are statistically significantly different. We propose NSGA-II as the best candidate for use in pairs trading strategies in cryptocurrency markets.

This research aimed to compare two strategies for vocabulary learning (digital-game-based learning and paper-based learning). The research was conducted during the first semester of the academic year 2022/2023. A total of 40 EFL undergraduate students within the Applied English Program of a private university located in the middle part of Taiwan were selected and divided into two groups: digital-based (n = 20) and paper-based (n = 20). The instrument developed by the researcher was pre- and post-vocabulary tests for both groups. The pre-vocabulary test was implemented to identify the level of students’ prior knowledge of vocabulary mastery. For the intervention, Kahoot! quiz exercises were conducted weekly for the digital-game-based group, while the paper-based group received the same quiz on paper every week. The post-vocabulary tests showed no significant difference between the students using digital-game-based quizzes and paper-based quizzes during the six-week intervention. Full article

Under the 2030 bilingual national policy in Taiwan, the financial industry encourages employees to use a digital innovation learning platform (English e-learning platform, EELP) to strengthen their language skills and improve service capabilities and improve the language skills of financial practitioners. In this study, we used the Technology Acceptance Model (TAM) to understand financial practitioners’ intentions to use the digital innovation learning platform. TAM is the one of most influential models for technology acceptance. In the study, a total of 528 questionnaires were collected from financial practitioners with 457 valid ones. The collected data were analyzed by descriptive statistics and regression analysis. From demographic variables, more female financial practitioners used the digital innovation learning platform than males. Most practitioners using e-learning were 50–59 years old in the position of a business manager with 11–15 years of experience. In the technology acceptance model, perceived ease of use and perceived usefulness had a significant positive impact on attitude to use. Convenience, safety, and attitude to use had significant positive effects on willingness. All the hypotheses for the technology acceptance model were supported. Full article

Guided by system science, we propose a cognitive model based on graph theory and explore personalized recommendation algorithms based on a deep knowledge point tracking model by integrating the learning characteristics, prior knowledge, and learning ability of learners. Recommendation of the knowledge point is provided by combining the deep knowledge point tracking model and cognitive model, and personalized curriculum recommendation is provided by combining a knowledge point tracking model and graph theory. A dynamic personalized learning path is recommended by combining the knowledge point network and a student model. Then, teaching resources are recommended, and learning efficiency is improved.

The Taipei Dome Complex is located in Taipei, Taiwan. It is a composite park with a multi-functional dome and incorporates a shopping mall, restaurants, cinemas, and an office building. In 2017, Taipei, Taiwan hosted the Universiade, and thousands of people protested. Smoke bombs were thrown, and the police were attacked. Due to its location in the “Circum-Pacific seismic belt” and the fact it is affected by the subtropical monsoon climate, Taiwan suffers frequent natural disasters. We aim to define the security risk factors for the Taipei Dome Complex by assessing flood simulation from the National Science and Technology Center for Disaster Reduction, earthquake simulation of the Taiwan Earthquake Loss Estimation System (TELES), and a case study of a terrorist attack. We propose 24 risk factors from five major perspectives: equipment safety, traffic accidents, human resources, security management, and disaster events. Full article

Prisons have always been considered self-sufficient, and government disaster response plans at all levels rarely mention prisons. Prisons may face emergencies such as earthquakes, floods, fires, prison escapes, or riots. Prisons are located in various disaster potential areas. If prepared, the safety of prison inmates can be secured. If it is not handled properly, society can be threatened. Through a literature review, TELES and SESS earthquake loss estimation system, and other methods, we sorted out three disaster risk factors, personnel risk, equipment risk, and management risk. In the safety part of facilities, old buildings, old prison walls, insufficient monitoring facilities, and insufficient prison space need to be included. The management aspect includes the potential of adjacent disasters. Insufficient regional and disaster prevention materials, medical materials, and connections with surrounding resources need to be solved. Full article

If we look back at the sense of place and deconstruct this concept, it is a combination of “space” and “meaning”, and cyberspace may be developed as a “place” that is different from the real world, being unique and charming and more desirable. The purpose of this study is to discuss the unexpected existing space hidden in the Internet under the premise of interlacing life experiences and the Internet. We analyze the relationship between social media-mediated user emotions and cyberspace through a relevant literature review and a questionnaire survey, and summarize the possible factors that influence the relationship between cyberspace and users. The results of the analysis provide suggestions for future designers to consider when creating spaces in the online world and directions for subsequent researchers. Full article

A construction site is an open and dynamic space. Construction accidents have been the top-ranked occupational accidents among all industries around the world. Due to the limited quality and quantity of occupational safety supervisors on construction sites, it is difficult to control or prevent risks in real-time. Therefore, a real-time safety warning system based on a deep learning technique (DL) is developed for lifting operations in building construction, called a portable lightweight lifting safety control station (PLSCS). Two modes can be switched manually by the supervisor. If the mode is switched to lifting control mode, PLSCS helps to ensure that nobody is in the hazardous area during lifting operations. The advantages and features of this system are as follows: (1) it warns of the potential safety hazards automatically during the operations; (2) it reduces the workload of occupational safety supervisors; (3) the system is self-powered and easy to carry and deploy. The system was tested and verified in the actual construction site. The results show that the system is useful for improving the safety of lifting operations. Full article

Digital play has gradually become popular in young children’s families, and electronic toys have become an important type of toy for young children. This study concerns preservice early-childhood teachers’ preferences about play and how their experiences with electronic toys in childhood influence their preferences about play. A total of 108 preservice early-childhood teachers participated in this study, and data were collected through questionnaires with them. The results revealed that these preservice teachers rated different play activities as follows: constructive play, expressive play, pretend play, digital play, and gameplay. In addition, preservice teachers who favored traditional toys in childhood preferred constructive play more than those who favored electronic toys. The results of the study provide useful suggestions for the design of electronic toys and preparation programs offered for preservice early-childhood teachers in the future. Full article

An ineluctable topic has emerged and needs to be treated in engineering programs for green energies. Particularly in the programs of electrical and systems engineering, students can acquire the capabilities to envision the arrival of green standards to generate clean energy sources. In this article, the introduction of new forms of green energy is systematically presented through a basic experiment in electricity in which a potato is used to investigate the current and electric power. The experiences were conducted at the 2022-I at a private university in Lima City. The results demonstrated that the topic of biofuel in the framework of green energy can be studied in undergraduate courses. Indeed, prospective students of engineering can be oriented toward research in engineering for the implementation of new electrical systems that provide electricity with low budgets. Full article

Currently, many swimming goggle lenses use optical plates to maintain zero refractive power in air and water. However, people’s widespread use of 3C products has increased myopia significantly, so lenses have a demand for refractive power. Lenses will have different refractive power problems in water and air media. Therefore, we solved the refractive power change in air and water by using a plane Fresnel lens with a diopter to replace plano-concave lenses. In this study, a first-order design was created and then the microstructure of the Fresnel lens was optimized using optical software. The Fresnel lens simulation results showed that the error was within 5%, which was compared with the data using the lensmaker’s equation calculation. For swimming goggles, this error value is tolerable for human vision. Full article

No matter how old people are, the ability to feel the sexual climax does not change. Whether a male can enjoy sexual pleasure in multiple sexual climaxes without pressures of the physical erection and ejaculations is a topic to search for, though. A young man can enjoy the thrill of riding on the sexual waves, while an old man is also supposed to also enjoy it in the sexual pool without any pressure of erection and ejaculations. The frequency of ejaculation gradually decreases with age, but satisfaction brought by sexual climax does not decrease. The physiological response to sexual climax may vary with age. As a result, the sexual climaxes of the male and the female in the sexual response cycle are worth exploring to evaluate the quality of sexual life. With this, interfering factors are also necessary to determine including the physical erection and ejaculation, the sexual pleasure, motivation, emotion, and satisfaction of the sexual climax for males. Then, the best solution (decision) for the development of the closed couple relationship can be found. Full article

The performance of a straight type of internally finned tube (SIFT) is studied using computational fluid dynamics (CFD). It is found that a longer fin yields a larger pressure drop that is nearly proportional to the fin length. When the fin length is larger than 30 d, the pressure drop is greater than that of a bare tube. The temperature uniformity decreases with the fin length of the SIFT. Furthermore, a smaller fin angle yields a larger pressure drop, while a larger fin angle yields better temperature uniformity. A larger contraction yields a larger pressure drop, too. Full article

This paper presents the design of a compliant rack and pinion mechanism with the support of a compliant rolling contact joint (CRCJ). The flexible strips are mounted to connect the rack and pinion to accelerate the mechanism. Two types of rack and pinion mechanism are proposed: rack and pinion mechanism and double rack and pinion actuator. The 3D model is created with finite element analysis (FEM) for structural analysis to observe the maximum strength and the deformation of the flexible strip. A 3D-printed model is proposed by using a fused deposition method (FDM) by printing layer by layer for experimental and demonstration purposes. In this study, we propose a set of examples to convert a traditional rigid body mechanism to complete a complaint mechanism to accumulate the actual function and also to increase the high possibilities of mounting.

We study the performance of a helical type of internally finned tube (HIFT), using computational fluid dynamics (CFD) to obtain optimal temperature uniformity and reduce the pressure drop. In comparison with a bare tube, the HIFT improved the temperature uniformity with a helix length of 10 d, which was enough to obtain satisfactory temperature uniformity. A smaller helix interval angle and a smaller helix pitch yielded a larger pressure drop. The temperature of the HIFT decreased with an increase in the helix pitch. Full article

A mathematical presentation of the surface rejuvenation model is used to relate the mean velocity and temperature distribution to the mean vortex dwell time and approach distance. Coupled with a proper estimate of these modeling parameters, it provides quantitative forecasts of the mean thermophoresis velocity. As expected, the particles obtain inertia along the wall from the eddies in the turbulent core and are trapped in the viscous sublayer where coherent temperature gradients exist in the wall region. Playing an important role in particle transfer, this results in particle transfer along the wall. Particle thermophoresis with small molecule diffusion may be the only mechanism that enhances the particle transfer process in the viscous wall region. Full article

Based on coal gangue, sintered red mud, and fly ash, which are primary industrial waste products, a high-performance cementitious material was developed that considered its composition, physical and chemical properties, and microstructure. The optimal ratio of the materials with an appropriate exciter content was determined through the production and testing of samples composed of various ratios. It was found that the compressive strength reached its maximum when the ratio of coal gangue: red mud: fly ash was 40:40:20 and the exciter content was 8%. The synergistic effect of the waste-based cementitious material and the exciter content was confirmed, which lays a foundation for the development of diverse waste-based industrial materials. The use of such materials helps reduce abandoned industrial waste and encourages the recycling of materials for various purposes. Full article

This study aimed to investigate the affective Kansei/affective design elements of Taiwanese wooden furniture and the consumer demand and perception for the design using Kansei engineering methodology and fuzzy theory. An online survey was conducted to carry out triangular fuzzy linguistic analysis from fuzzy theory and understand the consumers’ demands and perceptions of the design elements of wooden seat shapes. The research results showed that consumers agreed with “sturdy” the most, indicating the element needs to comply with the demand and purchase intention of consumers. In terms of the Kansei design elements of a rectangular seat shape, consumers’ agreement on “elegant” was medium, while consumers agreed with “novel” the least. The research results provide the Taiwanese wooden furniture industry and designers with a reference for decision-making, design, and manufacturing. Full article

Vortex-induced vibration (VIV) is the periodic motion of a bluff body caused by fluid flow and is widely discussed in the engineering field. With the advancement of science and technology, miniaturization and integration have become the mainstream trends in biomedical chips and electronic systems, resulting in higher heat dissipation requirements per unit area. Therefore, the improvement of the heat dissipation effect of movable structures in the flow channel has been widely discussed. Among them, adding VIV motion in the microchannel generates a vortex structure, which improves heat transfer efficiency. Different from the direct displacement method of active vibration, the passive displacement of VIV is a multi-physics problem. It needs to integrate the flow field and the spring-mass system of the object for fluid–solid coupling, which greatly increases the difficulty of analysis. In this study, the Immersed-boundary method (IBM) combined with the equation of motion is used to numerically study a vortex generator that is elastically installed in a microfluidic channel and is then used to enhance the convective heat transfer of nanofluids in the channel. Unlike the common body-fitted mesh, IBM greatly reduces the computational resources required for mesh regeneration when simulating the problem of object movement in fluid–structure interaction. In addition, Buongiorno’s two-phase mixing model is used to simulate the convective heat transfer of nanofluids in microchannels by considering the Brownian motion and thermophoretic diffusion of nanoparticles in the carrier liquid. By changing the important parameters such as nanofluid concentration, Reynolds number, mass ratio, and Ur, the influence of the response characteristics of vortex-induced vibration on the heat flow field in the microfluidic channel is discussed, and the key factors for enhancing heat transfer are found out.

An armor-piercing fin-stabilized discarding sabot is used with a spare shell for 30 mm chain artillery. Due to the limited firepower of the bomb, the limited domestic shooting range, and the high public awareness of environmental protection, it is not easy to test the intrusion force. Therefore, an armor-piercing fin-stabilized discarding sabot is simulated and analyzed to optimize the design of tungsten composition to save research and development costs and improve ammunition performance. The key work of this research includes three parts: pre-work, armor-piercing fin-stabilized discarding sabot drawing, and numerical simulation analysis. Establishing a basic reference data system for ammunition specifications is currently being developed through finite element simulation analysis including the establishment of an armor-piercing fin-stabilized discarding sabot model and performing optimization design evaluation analysis.

Based on DBR, a pressure vessel and standard vessel are designed using a public view and diagrams. They are formulated to a standard specification using the ASME pressure vessel code rules and the European standard EN13445. The pressure is determined under influence of a closed end. There are limitations to the structure of the container. Using DBA, several analyses were performed based on FEM to provide parameters to complete the DOE, and combined with DFA and DFM to verify that the analysis was conducive to giving users a good analysis plan. The core premise of this study is to simplify operation, to provide an exemplary user interface, observe various parameters according to requirements, meet pressure requirements during the reaction of polymer composite materials, and ensure that the temperature, strength, and manufacturing cost are within safety factors, to provide a good user experience.

To determine the road performance and optimum dosing of solid-waste-based gelling agents in road subgrade, we conducted unconfined compressive strength testing for clay, sandy soil, weathered sand, and crushed stone mixed with different proportions of solid-waste gelling agents and compared the results with the road performance of cement-stabilized crushed stone materials. The results show that the optimum admixture of cementitious materials for clay and clay is 8–10%. The optimum admixture of cementitious materials for weathered sand is 5–7%. The optimum admixture of cementitious materials for stabilized gravel is 5.5%. The late strength growth of stabilized gravel with solid-waste-based cementitious agents is significantly better than that of cement-stabilized gravel. Full article

Compared with traditional manufacturing methods, 3D printing is designed according to the needs of patients at a lower cost. Therefore, it has recently been developed vigorously in the application of medical equipment. The printing of biomedical materials with powder plastic (PEG-PCL) in the form of fused deposition modeling is one of the most recent key development projects. In this method, the plastic was heated and melted at the nozzle of the bucket and then printed. However, due to the existence of voids between the particles, the powder was melted, and the gas was coated in the melt. Due to the high viscosity of the melt, the air bubbles could not escape freely depending on the density difference, which led to a discontinuous plastic output during the printing process and, in turn, affected the appearance and material strength of the printed product. In this study, the Volume of Fluid method was used to simulate the rising process of bubbles in the molten liquid. By studying the internal flow of the liquid, the influence of the viscosity of different fluids on the rising of bubbles was discussed. In addition, the reliability of the simulation results was obtained through experimental verification. In the future, the rotating conical agitator should be used to generate forced convection inside the liquid to accelerate a rise in bubbles, and the influence of the conical agitator on the rise of bubbles at various speeds needs to be further studied. Finally, a suitable speed range was found for the most effective degassing effect. Full article

In this study, ZnO nanorods with a porous structure were successfully prepared using the chemical bath deposition (CBD) method. According to the surface and cross-sectional images photographed by scanning electron microscopy, we found that the diameters of samples with concentrations of 10, 30, 50, and 70 mM were 90, 141, 214, and 259 nm, respectively, with 6 h of deposition. The height of the nanorods was maintained at approximately 1.3 μm. The EDS material analysis showed that the ratio of zinc atoms and oxygen atoms in samples with different concentrations changed with the concentration of the growth solution. The column diameter of the zinc oxide nanorods prepared by the chemical bath deposition method was closely related to the concentration of the growth solution. The higher the concentration, the larger the column diameter. The height of the nanorods was directly proportional to the deposition time and was not influenced by solution concentration.

The architectural heritage of a remote village not only forms an important part of its local history but is also a sustainable source of knowledge. The purpose of this study is to introduce the environmental factors in the design of a traditional ancestral hall located in Xinpu Township, Hsinchu County, Taiwan. The content presented covers all scales of architecture, starting from large-scale urban design to small-scale building components. First, it presents the urban form of Xinpu. The environmental investigation is based on the nine main ancestral halls, corresponding to the local climatic conditions, the sun and shade conditions of the courtyard, and the orientation of the remaining traditional houses. Then, the architecture of traditional dwellings is introduced. Environmental studies are based on a computer analysis using Ecotect. Field studies include measurements of winter and summer air temperatures in a house, while computer analysis is conducted for sunlight and shading conditions for nine ancestral buildings. Combining Ecotect Analysis, Desktop Radiance, and WinAir4, daylight levels and airflow in the houses are simulated. The results are used to explain the university’s practice of social responsibility in rural areas. Full article

Owing to the severe development and progression of climate change and the greenhouse effect, carbon neutrality has attracted much research interest in environment-related social research. Specifically, in Article 12 of the Regulations on Community Development Work (RCDW) for more than 25,000 Taiwanese community development associations, carbon neutrality is the main purpose of environmental education, environmental protection and infrastructures, and social responsibilities. Carbon neutrality has to be instituted into efficient governance and operations to provide effective and diversified services for residents’ lives. Thus, sustainable strategies (environmental, social, and governance, ESG) need to induce effective and efficient carbon-neutral sustainable development in order to improve environmental conditions for the community’s residents without long-term government compensation and resources. Environmentally sustainable strategies focus on environmental protection and education for the whole community. Social strategies need to be associated with social responsibility and public services, while governance needs to be concentrated on sustainable operation and management. In this study, effective and efficient carbon-neutral sustainable development strategies were proposed for the community sustainability of community development associations. Full article

Weathered petroleum-contaminated soil was treated with Vetiveria zizanioides (Vetiver) and Cymbopogon nardus (Lemongrasss) to investigate the efficiency of phytoremediation. The initial total petroleum hydrocarbon (TPH) concentration of soil was 3000−8000 mg/kg, and after 6 months, the TPH concentrations were degraded by 50−75% under the action of soil native microbial. Planting vetiver and lemongrass stabilized soil pH and electrical conductivity, and it accelerated the decomposition of TPH in soil. Planting vetiver showed a better effect. After 6 months of planting, the TPH decomposition efficiency reached about 90%, and most of the easily decomposed TPH has been decomposed. The results of rhizosphere soil microbiota analysis also showed that planting vetiver increased the abundance of soil microbiota. Full article

Rainfall data are crucial in hydrology models. In this study, the assessment of two spatial interpolation approaches of Inverse Distance Weighting (IDW) and Local Polynomial Interpolation (LPI) for rainfall in Peninsular Malaysia was conducted. The daily precipitation for 515 rainfall stations across Peninsular Malaysia during 2011–2020 was used as the reference data. The performance of IDW and LPI was evaluated by the computation of the coefficient of determination (R²), the mean absolute error (MAE), and the root mean square error (RMSE). The results show that LPI methods surpass IDW methods on the annual scale rainfall interpolations in Peninsular Malaysia by exhibiting a better statistical evaluation. Full article

In central Taiwan, due to the complex urban regions and the distribution of industrial and agricultural areas, there are high potential risks of irrigation water pollution caused by urban drainage or industrial wastewater. Heavy metal pollution from industrial wastewater significantly impacts water and soil. In this study, time-lapse ion exchange resin capsules were used to investigate heavy metal water pollution in the Taichung irrigation area of central Taiwan. The resin capsules were put in pollution canals for a few days and retaken. X-ray fluorescence analysis was conducted to detect the amount of heavy metal absorption and investigate the degree of heavy metal pollution in the irrigation water. The investigation was performed from 2018 to 2021, and during which, 48, 140, 620, and 217 resin capsules were placed to investigate the pollution of the irrigation area. The results show that the Babao irrigation area in the Dajia River basin and the Dali irrigation area in the Wu River basin were significantly polluted with Ni and Cr. Ion exchange resin capsules were recommended as being a valuable tool for a quick test to investigate heavy metal pollution. Full article

With relatively high temperatures and evenly distributed precipitation throughout the year, outdoor thermal comfort is important in Taiwan. Thus, we discuss thermal comfort in different density areas with A: a low density (average buildings height/Street width ratio: 1.3, SVF: 0.28), B: a mid density (H/W: 2.75, SVF: 0.14), and C: a high density (H/W: 6.88, SVF: 0.11). Data were acquired through field meteorological measurements from the three sites on typical summer days from 15 to 17 July 2022. Around the Wanhua district of Taipei City, thermal comfort was obtained through the calculation of thermal comfort indices: physiological equivalent temperature (PET) and Universal Thermal Climate Index (UTCI). Results showed that different urban density areas had different thermal comforts; streets in A were more exposed to sunlight, causing the mean radiant temperature to be the highest; C had lower solar radiation and stronger wind with the highest comfort level; and B had higher air temperature but lower radiation than A. PET contributed to uncomfortableness in A. Thermal sensation vote results showed that B had the most “uncomfortable” votes because wind speed in B was the lowest. Medium-density urban areas had enough solar exposure on the pedestrian level, but not enough wind to dissipate the heat. PET was more sensitive to mean radiant temperature. These findings provide a guideline and technical reference for urban designers to mitigate the high temperatures of summer in urban areas and improve thermal comfort to create a healthy environment and encourage people to utilize outdoor environments.

We analyze the recent media reports related to food and agriculture education (FAE) in Taiwan and present the main aspects of the FAE in different ways such as historical society and ethics, food and agriculture industry and responsibility, food and agriculture culture preservation, and education and health promotion. The reports are classified into seven categories: culture, life, agriculture, campus, society, environment, and industry. The results point out the enhancement of the sustained development of the FAE in the post-legislative era due to the increased consolidated relationships among the sustainable development goals (SDGs) and FAE in the food (production and marketing certification), agriculture (commercializing organic agriculture certification), and travel (friendly conservation tourism). Further research needs to focus on the main evaluated aspects of FAE that appear more frequently in the related research for the promotion of education and health, and historical and ethical justice. FAE seems to be preferred in the metropolitan area while teaching in the cultural field is more important in the non-metropolitan area than in the metropolitan area, which needs further study.
