Subways are eco-friendly public transportation that can transport large numbers of passengers safely and quickly. It is necessary to predict the accurate number of passengers in order to increase public interest in subway. This study groups stations on Lines 1 to 9 of the Seoul Metropolitan Subway using clustering analysis. We propose one final prediction model for all stations and three optimal prediction models for each cluster. We found three groups of stations out of 294 total subway stations. The Group 1 area is industrial and commercial, the Group 2 ares is residential and commercial, and the Group 3 area is residential districts. Various data mining techniques were conducted for each group, as well as driving some influential factors on demand prediction. We use our model to predict the number of passengers for 8 new stations which are part of the 3rd extension plan of Seoul metro line 9 opened in October 2018. The estimated average number of passengers per hour is from 241 to 452 and the estimated maximum number of passengers per hour is from 969 to 1515. We believe our analysis can help improve the efficiency of public transportation policy.

Fear to start-up failures has been known to have a negative impact on entrepreneurial intention. This is one of the reasons why the government adopts a policy to help university students overcome their fear of start-ups. Setting educational goals to foster innovative and progressive entrepreneurs, universities have been conducting entrepreneurship education, but it is hard to say that constructive results have been achieved so far. Rather than adopting the practice of optional entrepreneurship education, there is a need to have all university freshmen mandatorily take the course of entrepreneurship education. This study aims to uncover the impact of more aggressive entrepreneurship education position in the university by analyzing empirical data. The relationship between an entrepreneurship level and entrepreneurial intention was tested, and start-up fear was also considered. In the research model, self-leadership and self-efficacy were included as regressors to entrepreneurship levels. Especially, this study tested moderate effects of start-up community during the course. The results from the sample of 2,500 freshmen indicate that entrepreneurship level is significantly improved by taking the course; however, fear to start-up failures remains still. In addition, empirical findings show that putting start-up communities in the entrepreneurship education helps students by moderating self-leadership and self-efficacy. This study extends our knowledge of entrepreneurship education in university by analyzing university freshmen data empirically.

The value and importance of Gamification has intensified as the way Gamification is applied to social networking applications has added to users' interest and involvement to the product. Gamification entails the adoption of gaming techniques and modes of thinking in non-gaming domains to elicit user engagement. To this end, the paper draws on Gamification's analytical model, Octalysis, with the aim of identifying user loyalty of the three major Chinese social networking applications and extracting their characteristics. In this regard, the first task in the advancement of the study is to establish an understanding of the components and characteristics of Gamification within the context of available examples. Next, a questionnaire survey covering China's three dominant social applications, WeChat, QQ, and Xiaohongshu, is administered and their user loyalty is examined through Octalysis's eight analytical frameworks. By virtue of analysis, the results demonstrate that the three elements of game mechanics, Point, Badge, and Leadboard, which are external to the game, fail to sustain the user loyalty, but are merely a means to an end. Only by including a combination of social application features, contents and user needs can Gamification considerations be maximized to ensure that users are subjectively engaged with the product.

In the era of the 4th industrial revolution, public libraries need a strategy for promoting intelligent library services in order to actively respond to changes in the external environment such as artificial intelligence. Therefore, in this study, based on the concept of artificial intelligence and analysis of domestic and foreign artificial intelligence related trends, policies, and cases, we proposed the future direction of introduction and development of artificial intelligence services in the library. Currently, the library operates a reference information service that automatically provides answers through the introduction of artificial intelligence technologies such as deep learning and natural language processing, and develops a big data-based AI book recommendation and automatic book inspection system to increase business utilization and provide customized services for users. Has been provided. In the field of companies and industries, regardless of domestic and overseas, we are developing and servicing technologies based on autonomous driving using artificial intelligence, personal customization, etc., and providing optimal results by self-learning information using deep learning. It is developed in the form of an equation. Accordingly, in the future, libraries will utilize artificial intelligence to recommend personalized books based on the user's usage records, recommend reading and culture programs, and introduce real-time delivery services through transport methods such as autonomous drones and cars in the case of book delivery service. Service development should be promoted.

Tattoo, which has been 5000 years' history is the symbol of the collective society. It was used as one of the methods not only to defense and camouflage but also to decorate themselves. In modern society, tattoo culture is either limited to ethnic minorities or be used as a decorative element of personal preference. Among them, the Chinese ethnic minority, the Dai, is still maintaining its tattoo culture, but gradually faded. Hence, the necessity of protecting the tattoo culture of the Dai is essential. The procedures and methods of this study were conducted by analyzing an antique book, explore residential areas, data research, and data collection through interviews. According to research, the tattoo culture of the Dai has been consistently passed down through traditional tattoo pictorial books, the memories of tattooists, and the stories of people who got tattoos. However, the Dai's traditional culture and customs are influenced by the China political reform between 1952 and 1956, confirming that the size of tattoo culture was reduced than before and evanesces. As a result, in order to inherit the ethnic minorities Dai's tattoo heritage, records of tattoo culture are required. Besides, it is considered that the records of tattoo culture and interpretations of tattoo culture by tattooists and the people who got a tattoo due to aging in the future should be studied.

This study analyzed the effects of e-sports games on psychological well-being and life satisfaction of individuals by focusing on social and psychological aspects, recognizing e-sports games as subjective area activities based on psychological experiences as well as a means of leisure activities. To this end, 250 game users with actual experience in online games were analyzed using a structural equation modeling(SEM). The research results are as follows. First, except for other's emotion appraisal, which was a sub-factor of emotional intelligence of e-sports game users, self-emotional appraisal, use of emotion and regulation of emotion were found to have a significant positive effect on psychological well-being. Second, psychological well-being in e-sports games was found to have a significant positive relationship with life satisfaction, and psychological well-being was found to significantly mediate the relationship between emotional intelligence and life satisfaction. The findings of this study imply that managerial implications for related organizations as a platform that could support individual psychological well-being in a situation where the stress level of young adults as well as teenagers in a non-face-to-face environment is increasing.

World-widely, there has never been a greater need for people to access high-quality expertise about the effective and safe use of medications. Therefore, the profession of pharmacy should meet these needs of the times, as the demographic shifts have led to a situation where older adults now outnumber children, and polypharmacy is also a commonplace. However, the reimbursement system covered by the National Health Insurance (NHI) in Korea is still limited to the traditional dispensing and compounding role of pharmacist. To provide a take-home message to Korean pharmacy reimbursement system, we aimed to review and analyze the international trends in pharmacy remuneration systems. This is a comparative study between Korea, Japan, the United Kingdom, and the United States. Comparison was conducted by reviewing each country's policy and enforcement programs, as well as the related literature. Japan, the UK and the US systems remunerate diverse patient-centered pharmaceutical care services. The Korean pharmacy service fee is, however, narrowly focused on the traditional product-oriented pharmacy services. This study discussed the future direction of improving pharmacist reimbursement systems in Korea, by expanding professional pharmacy service coverage and diversifying fee schedule.

Today, the medical system is changing into a comprehensive health care system in which collaborative relationships between medical professionals and non-medical personnels in neighboring occupational areas. The current medical act brands such "collaboration" as unlicensed medical practice, and punishes non-medical personnel who acted in the risk management of doctors as well as doctors collaborated with non-medical personnel as unlicensed medical practice. In order to narrow the gap between the legal system that regulates unlicensed medical practices and the medical reality, it is necessary to overcome the structural limitations of dualistic, nationalistic, and identity-oriented regulation of unlicensed medical practices. The legal interests of unlicensed medical practice have a dual nature as a personal legal interest of "human life and body" as well as a national legal interest of "maintenance and protection of the nation's medical license system", and it should be noted that the criteria for judging the legal interests protected by the regulations of criminal punishment should be found in "personal legal interest theory." In addition, when determining which behavior is a medical practice and evaluating its risk, the dimension of behavior and measures should be considered in a fair manner without being biased against the subject (identity) of the action. In other words, judging unlicensed medical practice should depend on whether the risk of side effects that may result from the act is reasonably managed. Considering the prospect of therapeutic dialogue between medical professionals and patients, it would be desirable for medical law policies to move in a way that does not fundamentally block the possibility of collaboration among pluralistic medical personalities.

Opinion polls have become a powerful means for election campaigns and one of the most important subjects in the media in that they predict the actual election results and influence people's voting behavior. However, the more active the polls, the more often they fail to properly reflect the voters' minds in measuring the effectiveness of election campaigns, such as repeatedly conducting polls on the likelihood of winning or support rather than verifying the pledges and policies of candidates. Even if the poor predictions of the election results of the polls have undermined the authority of the press, people cannot easily let go of their interest in polls because there is no clear alternative to answer the instinctive question of which candidate will ultimately win. In this regard, we attempt to retrospectively grasp public opinion on the 20th presidential election by applying the 'YouTube Analysis' function of Sometrend, which provides an environment for discovering insights through online big data. Through this study, it is confirmed that a result close to the actual public opinion (or opinion poll results) can be easily derived with simple YouTube data results, and a high-performance public opinion prediction model can be built.

The purpose of this study was to look into how social support for high school students was affecting suicidal ideation and verify how the moderating effect worked on risk factors in the relationship between social support and suicidal ideation. Specifically, three sub-factors of social support were classified into friend support, teacher support, and parent support, and were set as independent variables. In addition, suicidal ideation was dependent variables, gender, grade level, and school type as moderating variables. The main research results are as follows. First, teacher support, friend support, and parent support all appeared to have a significant negative effect on suicidal ideation. Second, the suicidal thoughts were higher in female students than in male students than in male students and in students of general high school than in those of vocational high school. Third, support from friends and parents was more effects in reducing suicidal thoughts for female students than male students. Fourth, the effect that teacher support that support and parent support reduce suicidal thoughts was greater for first graders than second graders. Bases on the results of the analysis, interviews were also conducted with high school teachers. Through the results of this study, I would like to propose practical measures to alleviate social problems related to suicide in high school students and to provide basic data for policy measures.
