For that, 21 executive officers from 19 organizations and agencies related to sports policy were selected as study subjects, and, the materials collected from whole twice surveys on them were analysed by Ucinet 6 and Expert Choice 2000 program. As the results, the governmental organizations like the Blue House and Ministry of CultureㆍSports and Tourism composed the central position group of sport policy network of Korea, and took the main functions of planing and arrangement within their main roles of policy agenda formation and policy decision, so, sport policy network of Korea could be called centralized network by government. And, in cases of private agencies, Korea Sports Council composed the central position group only in policy network of professional sport, Korea Council of Sport for All of sport for all, and Korea Sports Association for the Disabled of disability sport, and, each of them took the main roles and functions of policy execution in their fields, so, it was obvious that the private agencies were divided into their own sport policy areas.
PURPOSE This study comprehensively examined the aerodynamic and flight characteristics of modern soccer balls, focusing on their design evolution and performance attributes. METHODS The aerodynamic characteristics of five types of World Cup balls (2006 Germany World Cup, 2010 South Africa World Cup, 2014 Brazil World Cup, 2018 Russia World Cup, 2022 Qatar World Cup) and five types of Euro tournament balls (EURO2008, EURO2012, EURO2016, EURO2020, EURO2024) were examined, along with their respective design changes. RESULTS Through detailed analysis, significant variations in aerodynamic properties among soccer balls used in various tournaments were identified. Recent advancements have resulted in faster transitions towards critical Reynolds numbers, indicating improved stability in flight trajectories. This enhancement was attributed to the augmentation of surface roughness, which plays a crucial role in enhancing aerodynamic stability and overall performance. 2D simulations simulating powerful goalkeeper kicks revealed distinct differences in flight distances among different soccer balls; the Jabulani ball used in the 2010 World Cup exhibited the longest flight distance, while that of the 2024 Euro ball was the shortest. CONCLUSIONS Variations in surface texture significantly impact aerodynamic properties, affecting flight distance, arrival time, and height. This study underscores the significant design enhancements in modern soccer balls that optimize aerodynamic stability and performance, with modifications aimed at improving flight characteristics and enriching player experience.
[Purpose] A potential issue for wheelchair sports are the characteristics of wheelchair design. The purpose of this review was to investigate the characteristics of design in wheelchair sports including the height of seat, camber and handrim size for improving the performance. [Results] The optimum height of seat related to trunk, arm length and handrim size. The lower seat showed the push efficient highly, while higher seat increased the energy expenditure. In energy expenditure, the optimum height of seat was 100-120° of elbow angle. Handrim size play the role in gear. The smaller handrim size acts like high gear, it gains disadvantages in acceleration, it gains advantages in maximum velocity. On the contrary, the higher handrim size acts like low gear, it gains disadvantages in maximum speed, it gains advantages in acceleration. The ratio of gear consideration in power and velocity. When increased camber enhanced the lateral stability, easier catch the handrim and easier arm motion. So it improved the energy expenditure and push technique. When increased camber enhanced the mechanical efficiency and stability, but it decreased the power. The racing wheelchair camber using the 8° and 10°. [Conclusion] Athletes, coaches and wheelchair experts are provided with insight in the performance effect of key wheelchair design settings, and they are offered a proven sensitive method to apply in sports practice, in their search for the best wheelchair-athlete combination.
PURPOSE This study aimed to verify the relationship between adolescent athletes’ julsil, competitive trait anxiety, and self-management. METHODS A total of 370 adolescent athletes who were registered with the Korean Sport & Olympic Committee participated in the survey; 24 insincere responses were excluded from the analysis, leaving a total of 346 participants. After verifying the construct validity of the measurement tool used in the survey, statistical and correlation analyses were performed. The research model was subsequently verified using structural equation modeling. RESULTS Adolescent athletes’ julsil had a significant positive effect on self-management but not on competitive trait anxiety. In addition, self-management was found to have a significant negative effect on competitive trait anxiety, and also completely mediated the relationship between julsil and competitive trait anxiety. CONCLUSIONS Adolescent athletes’ julsil does not increase competitive trait anxiety, but rather plays a role in reducing it by increasing self-management. These findings unveil mechanisms through which julsil can be used to enhance athlete performance.

Purpose Based on Haidt's social-intuitionist theory, this study analyzes the differences in ethical decision-making between sport athletes and the general public in order to understand the ethical judgment tendencies of athletes and examine the determining factors influencing their judgment from the perspective of their environment. In so doing, this study hopes to motivate education for enhancing ethical consciousness as well as institutional policy. Methods To this end, 200 elite athletes in their twenties registered for more than 10 years at the Korean Sports Association and 200 college students in their twenties from five universities in Seoul were selected for comparison. Response trends for each item were analyzed by percentage, and differences between groups were confirmed by the χ2 test method. Results The results are as follows. First, in general ethical situations, athletes usually showed a compulsory ethical view that emphasized principles, whereas in a sports situation, they showed a double consciousness and revealed a very strong consequential ethical view which put much emphasis on outcome. Second, athletes strongly maintained a Confucian ethical view that recognized ethics as a norm compared to the general public and, as a result, it was found that paternalism was relatively stronger than rationalism in their ethical decision making. Third, athletes regarded other people's thoughts and group interests as important criteria for ethical decision-making rather than individual thoughts and interests, and showed a group-centered mindset which emphasized group harmony and relationship. Fourth, while the general public viewed excellent athletes as those with excellent skills and good personality, and valued their morality, athletes thought relatively little of the influence and importance of morality in their success. Finally, it was found that coaches and managers were fundamental to the formation of the athlete’s moral view. Conclusion An in-depth understanding of sports participants' ethical awareness should come first in order to enhance ethical consciousness in sport. I hope this study will work as a catalyst for research which approaches athletes' ethical consciousness from a socio-cultural context.

PURPOSE Since the COVID-19 pandemic, the demand for home training, with exercises or workouts at home, has steadily increased. As a result, the popularity of home training YouTube content, which shows how to use exercise equipment or workouts without professional influence, has also increased. Therefore, this study focused on the characteristics of YouTube home training content (specialization, diversity, and interaction), personal health awareness, exercise awareness, and expectation-confirmation model to identify which required exercise continuation intention through YouTube home training. METHODS SPSS and AMOS software were used to conduct frequency, reliability, and confirmatory factor analyses, as well as to conduct correlation analysis and construct a structural equation model. RESULTS First, health and exercise awareness had a positive effect on confirmation. Second, among the characteristics of home training content, only specialization had a positive effect on perceived usefulness. Third, confirmation had a positive effect on perceived usefulness and viewing satisfaction, perceived usefulness had a positive effect on viewing satisfaction and exercise continuation intention, and viewing satisfaction had a positive effect on exercise continuation intention, which proved the expectation-confirmation model in this study. CONCLUSIONS To increase exercise continuation intention through home training YouTube content, creators need to produce professional content that can stimulate viewers' internal motivation.
This study was to identify the structure of anger behavior that athletes illustrated in competitions. In order to achieve research purpose, 167 high school, college, and professional athletes responded to open questionnaires. Targeting 541 players, the structural validity of psychological measurement was verified. As a result of analyzing the sources of anger behaviors during matches, four factors of anger-out, anger-in, anger control, and anger-helplessness were deduced. Afterwards, the validity of 4 factor-model was verified through correlation analysis with trait anger and verification of group differences. That is, the level of trait anger had a positive relationship with expression of anger-out and anger-helplessness while it had a negative relationship with anger-in and anger-control. Especially, the behavioral aspect such as anger-helplessness is a structure that has not been found in other criteria of anger behavior and it reflects the uniqueness of sports situation. Based on such results, the significance of sport anger behavior and implications were discussed.
