  • Purpose: The core purpose of this study was to objectively evaluate the performance of Asian countries participating in the 2018 FIFA World Cup using social network analysis. Method: The subject of study included 5 Asian countries participated in the 2018 FIFA World Cup in Russia, using pass data for each position based on official data provided by FIFA. The processed data are made into symmetric matrices and the research perform a centrality analysis using Ucinet6, a social network program. Results: The results of the study are as follows. First, when the pass success rate was more than 80%, the ball possession rate was more than 50%, and the actual ball possession time was also confirmed to have 30 minutes. Second, the centrality analysis confirmed that players with high degree centrality also have a high closeness centrality, which can be information that can objectively evaluate major attack directions and key players. Conclusion: The results of this study can be used as an objective indicator to identify key players and evaluate their performance through passes by players in team sports events. However, due to the nature of the World Cup games, it is difficult to secure a lot of match data by country, and it is a pity that players who have not participated in the games due to injury cannot be evaluated. Based on the results shown in this research, we hope that it will be used as a new evaluation method to identify key players and objectively analyze each country's game patterns in order to advance to the 2022 Qatar World Cup finals, and it can be used as an analysis method that can objectively evaluate not only soccer games but also other team sports games through social network analysis.

Method: To achieve the purpose of this study, the frequency analysis was performed to examine and understand the general characteristics of the research subjects, and the Cronbach's α coefficient was calculated to validate the reliability of the survey questionnaire. Furthermore, the one-way ANOVA was conducted to examine the differences between the offensive techniques and defensive techniques according to the athletes’ career. Results: As a result of the study, it turned out that there were significant differences across hand techniques, waist techniques, foot techniques, offensive techniques, and defensive techniques. Examining the techniques, it turned out that there were significant differences in offensive techniques among the hand techniques, pull and throw, throw or destroy with shoulder, and grab a single color and throw, and all techniques among the defensive techniques had significant differences. Conclusion: As a result of this study, it turned out that the greater the career, the higher the utilization of hand techniques and foot techniques among the offensive techniques, and the less the experiences, the higher the utilization of waist techniques. As for the defensive techniques, the greater the career, the utilization of hand techniques, waist techniques, and foot techniques all turned out to be high. However, among the waist techniques, hold belt, lift and throw over with waist and counter attack using opponent's techniques turned out to be high, the less the career.

  • Purpose: The purpose of this research is to boost e-sports industries by conducting a comparative analysis on the current status of sponsor companies growing together with the Chinese professional e-sports competitions to understand the relationship between Chinese e-sports competitions and sponsor companies. Method: Based on the League of Legends Pro League, China's most influential e-sports competition, we would like to examine the relationship between sponsor companies and e-sports industries through longitudinal and cross-sectional comparisons of sponsor status from 2014 to 2020. Results: This resulted in the following: First, due to the accurate positioning of users, the first party competitions showed higher recognition or influence than the third party competitions. Based on the fact that mobile e-sports products can easily attract young users due to their low entry barriers, mobile e-sports products and competitions are important growth engines for the development of the e-sports industry. In addition, it has been shown that non-pro leagues support the development of professional leagues and that professional leagues are indispensable to interact, complement and promote the development of non-professional leagues. Second, according to an analysis of the sponsorship status of global e-sports events, computer and peripheral companies as computer and related fields were most actively sponsoring e-sports competitions, and the support of global companies was steadily increasing. Finally, after looking at the sponsorship status of e-sports competitions in China, it was found that e-sports sponsorship is a major source of income in the e-sports industry and is growing together with the participation of influential sponsor companies. Conclusion: In the League of Legends event, China's most influential e-sports competition, teenagers and 30s were the main sources of income, with mostly male products-oriented sponsor companies. However, if women's participation is steadily increasing and men and women's competitions are held to attract sponsors and marketability, e-sports can grow together with the attraction and participation of global sponsor companies.

  • Purpose: As it is the mission of coaches to appropriately guide their athletes on ethical and moral character, the role of sports coaches is crucial beyond anything, and it is also necessary to consider the guiding beliefs and methods which lead the students(or trainees) in the desired direction if sports coaching or guidance is more than merely an educational role to play. Hence, the purpose of this study is to examine and articulate the professionalism and ethical sensitivity of coaches, which have an important effect on the sports leagues as well as sports teams and athlete management, further to the effect on the guiding beliefs, thereby exploring an efficient operational method for managing and fostering sports teams and athletes. Method: In this study, as of 2021, the coaches who were formerly professional sports athletes were used as the population, and as for the sampling method, 250 people were surveyed by the convenience sampling, while the survey was conducted by using the self-administration method, and among the collected questionnaires, those of 284 respondents were used as valid samples, excluding the data with insincere responses or omissions of some of the details of the survey. Results: As a result of the factor analysis performed on professionalism, ethical sensitivity, and guiding belief, the professionalism was consisted of professionalism factor and technical requirement factor, while ethical sensitivity was consisted of one factor for the ethical sensitivity factor, and guiding belief factor was consisted of the 3 factors of behaviorism factor, interactionism factor, and maturationism factor, respectively. As for reliability, it turned out that professionalism factor was α=.795, technical requirement factor α=.692, ethical sensitivity factor α=.799, behaviorism factor α=.800, interactionism factor α=.835, and maturity factor was α=.697, respectively. As a result of the correlation analysis performed, it turned out that there was a positive(+) relationship between all of the factors, and it also turned out that the professionalism factor influenced the ethical sensitivity factor and the educational belief factor. Conclusion: In order to achieve the purpose of this study, it is evident that the professionalism of sports coaches influences ethical sensitivity and guiding belief based on the results of the questionnaire. It is considered that it is necessary not only to explore the means to help improve the professionalism of sports coaches, which influences the ethical sensitivity and guiding beliefs of the sports coaches’ education, but also create and form an overall environment for the self-development of the sports coaches.
