The total data that is analysed by SportsCode and SPSS(correlation analysis & chi-square test)have showed that the top ranked countries had a higher foul frequency than the lower ranked nations. According to the situation that has showed the result of the analysis, it showed that there was no difference between the results analysed on the foul type and the attacking and defence situation but it has indicated that area, game situation and the cause of fouls showed there was a significant difference.

We use a Markov chain model to analyze the Korean Baseball League. We derive the distributions of the number of runs scored and the number of batters that complete their turn at bat in a baseball game using the time inhomogeneous Markov chain. The model is tested with real data produced from the 2011 Korean Baseball League.

For the effective questionnaire survey, After analyzing the purpose and purpose of the research, participants were asked to collect data. The collected data were analyzed using SPSS statistical package after data coding and cleaning process. The results of this study are as follows. First, the effect of professional sports viewing factor on brand image was 45.1%, and the factor of pro sports viewing was significant in stadium, competition situation, and promotion of viewing, and had no effect on viewing cost. Second, the influence of professional sporting factor on the satisfaction of the team was 42.5% in explaining power, which was significant in the stadium, the competition situation, the cost of visiting, and promotion of viewing. Third, the influence of professional sports viewing factor on team reputation was 62.1%, and the factor of professional sports viewing was significant in promoting stadium, visiting cost, and viewing, and had no effect on economic situation. The implication of this study is that in order to increase the brand value of the club, it is much more effective to increase the quality of facilities and food and beverages and to activate events for the audience than to lower the cost of viewing.

이 논문은 주식투자 결정과 도박(gamble)의 심리가 상호 연관성이 있는가와 관련된 것이다. 집계변수(aggregated level)에서 경기가 불황일 때, 개인투자가들은 직접 복권(lottery tickets)을 구입하거나 복권과 같이 일확천금을 누릴 수 있는 동시에 위험성(risk)을 수반하는 주식을 선호하는 경향이 있다. 즉 경기가 불황에 놓일 경우에는 개인투자가들은 이러한 복권형(lottery-type) 주식과 복권(lottery)의 구매 및 보유를 늘리는 경향이 있다는 것이다. 특히 이러한 경향은 저소득 계층(low-income investors)과 청년, 교육의 혜택을 덜 받은 부류의 독신자, 대도시 거주자, 미국의 경우 흑인(African-American)과 히스패닉 등의 사회적 약자 등으로 알려지고 있다. 이러한 일반적인 경우가 데이터를 통해 알아볼 수 있는 지와 관련하여 실증분석 하였다. 하지만 이 분석을 통하여 개인투자가들이 경기불황일 때 위험한(risky) 주식의 보유 경향을 늘린다는 가정을 지지할 수 있는 결과를 도출하지 못하였다.

축구 비디오를 분석하고 이를 팀 전략 수립에 활용하는 축구 비디오 분석관의 역할이 강조됨에 따라, 축구 비디오에서 주요 이벤트의 탐지와 같은 절차적 기능에서 부터 고수준의 해석 방법에 이르는 다양한 기능들이 요구된다. 본 논문에서는 축구 웹 캐스트에서 실시간으로 제공하는 텍스트 정보를 기반으로 메타데이터 키워드 매칭을 통하여 축구 경기의 다양한 속성들을 추출하고 텍스트 마이닝의 대표적 해석 기법인 연관규칙 마이닝을 사용함으로써 축구 경기의 전략 수립이 가능한 고수준의 해석 방법을 소개한다. 실제 2010년 월드컵의 스페인 경기를 중계한 웹 캐스트의 텍스트 정보를 대상으로 제안된 방법론의 타당성을 검증한다.

본 논문에서는 하이라이트의 연관성을 이용한 분석 방법을 제안한다. 멀티미디어와 동영상 서비스의 발달과 더불어 운동 경기의 내용을 자동 분석하여 하이라이트 추출이나 방송 중계 등에 이용하고자 하는 시도가 많이 이루어지고 있다. 동영상은 텍스트나 정지 영상에 비해 방대한 데이터로 구성되어 있다. 그러므로 경기 내용을 효과적으로 파악하기 위해서는 내용 기반의 주요 경기내용(High light)만을 추출 디스플레이 하는 기술이 필요하다. 본 논문에서는 스포츠와 관련된 동영상에서 자동으로 하이라이트 부분을 검출하는 기법을 개발하였으며, 이 기법을 방송용 축구 경기 동영상에 적용하여 하이라이트 추출을 시도하였다.

Our study examines the relationship between coach turnover and professional sport team performance using the evidences of Korean professional soccer teams. We collected panel dataset of 304 team-year observations and 96 coaches from Korean professional soccer league during the period of 1983-2013. Among them, our final sample is comprised of 226 observations and 81 coaches manifested for fixed-effect generalized least square (GLS) regression analysis. Drawing on sport management literatures and organizational learning theory, we argue that it takes time for a new head coach to take charge of the team in which the new leader who secure more time to interact with organization members is better able to remodel and improve team performance. Our empirical findings reveal that off-season coach turnover has a positive impact while turnover during the season has its negative influences on team performance. In addition, we find that subsequent team performance in association of off-season coach turnover is comparably better than that of on-season succession. The results show that coach succession rendered from inside the professional soccer team mediates the relationship between coach turnover and team performance. Our findings imply that coach turnover in professional sport teams is a significant factor affecting team performance.

Path analysis is a useful method to find out direct or indirect effects between variables. Compared to regression analysis for studying the casual relationship, this method has a good advantage. In this study, I want to figure out direct or indirect relationships between golf skills and adjust average scores using path analysis. To analyze data, I applied AMOS in SPSS and collected data in 2010 PGA.
