This thesis analyzed that which countries won the Olympic medals more efficiently at the Olympic Games. Unlike the previous studies, I measured efficiency under the CRS, found implications for investment to improve sports skills through understanding the characteristics of sports race. A methods for research is a DEA-based approach which measures efficiency by using the data only, not assuming the parameters. The inputs are total population and GDP, the output is Olympic medals at 2004 Athens Olympic Games and 2006 Turin Winter Olympic Games. I applied different weights based on the medal colors. The results showed the tendencies that the larger the scales of total population and GDP were, the lower efficient values were. These tendencies imply that sports skills are related with the law of diminishing returns and international convergence. According to these phenomenons, surging investments for sports performance are hard to get proper justification. In the case of limited resources, investing uniformly in various sport entries is more productive than in just one or two sport entries.

Horseback riding, shooting, golf and other sports that make up the visuals, the background graphics in the game is an important factor influencing the outcome. But they need to play directly from the site is limited, and sports simulation games and the realistic representation of real-time operation since the fall of the background. In this paper, to overcome the limitations in the field for the game by converting pictures 3d graphic modeling. z-depth by using a special technique for expressing the perspective of the analysis of the sport and VR (virtual reality) simulation to study the background to the development. In this study, background realistic VR implementation of sport Journal of Sports Science and will contribute to the development.

This study empirically analyzes the effect of a sports club's performance and social media operations on online information search volume, reflecting fan engagement. Additionally, it confirms that such effect can vary depending on the issuance of sports fan tokens. The analysis of the data resulted in the support of all four hypotheses presented in this study. The team's goal differentials during the games exhibited a significant and positive effect on the online information search volume by fans. Furthermore, the quantity of a team's social media posts also showed a significant and positive effect on the online information search volume. The aforementioned effects of the team's game-related performance and social media activity on the online information search volume appeared to be strengthened when the sports fan tokens of the team were issued. This study conducts an empirical analysis of fan engagement in sports clubs and delves into the marketing dimensions of sports fan tokens. By doing so, it broadens the research scope within sports marketing and offers practical insights for the development of marketing strategies by sports clubs.
