The purpose of this study was to explore which factors mostly influenced players' tour results employing tour skill factors provided by LPGA. For this study, Top 10 LPGA players' stats during 9 years (2004 2012) were used. As matter of fact, 10 variables were used like average score, top 10 finish, average putt, average birdies, average eagles, driving distance, driving accuracy, greens in regulation, sand saves, putts per GIR. and prize money earning. Stepwise multiple regression was conducted using SPSS win 20.0. Results indicated that the most influential tour skill factor to 9 seasons' results was average score, second influential factor was average putt, and the third factor was driving distance, and then top 10 finish was the fourth. Also on a year on year basis, 2004 was average score, 2005 was GIR., 2006 was average eagles, 2007 was top 10 finish, 2008 was average score, 2009 was average putt, 2010 were average score, GIR. and putt per GIR, 2011 was average birdies and 2012 was putt per GIR.

This study is to investigate the effect of Chinese university track and field athletes on their athletic commitment and performance. The men and women aged 19 or older were selected as a population for athletes from Hanam University, Jeongju University, and Hanam Normal University, and 1400 questionnaires were distributed using the Convenience sampling method. The results obtained by performing data processing are as follows. First, all factors had a statistically significant effect on performance in the effect of sub-factors of exercise commitment (cognitive commitment, behavioral commitment). Second, all factors had a statistically significant effect on the performance of the sub-factors of exercise commitment (cognitive commitment, behavioral commitment). Third, all factors had a statistically significant effect on the effect of sub-factors of exercise commitment (cognitive commitment, behavioral commitment) on concentration.

This study examined the factors affecting the team identification of professional baseball fans. The factors were divided into the fan factor, game factors, and other factors. For the analysis, two investigators visited stadium three times in total and a total number of 297 spectators were sampled using a convenience sampling method from three baseball teams. For the fan factor, a fan who began supporting his/her team from childhood or after childhood was used as a dummy variable. The interaction effects between the fan factor and other variables were investigated to offer a stereoscopic understanding about the role of kids marketing. In addition, three game factors and four non-game factors were analyzed. The results regarding fan variable and interaction effects were obtained. Fans from their childhood have much stronger team identification, and show interaction effects with the players. Regression analysis revealed player, promotion and fan service, price, and regional connection to have positive relations with team identification. This study is especially meaningful in a sense that it has proposed positive results regarding marketing to children, and the results will contribute to both the academic field and the industry.

스포츠 통계와 관련된 주제들은 경기결과의 설명 예측력 분석, 선수와 팀 평가, 경기내용의 요약, 경기의 환경적 요인 평가, 경기 규칙 분석, 경기결과의 시각적 표현, 토너먼트 구조 연구 등의 영역으로 다양하다. 이 글에서는 야구 축구 농구 테니스 종목을 중심으로 통계적 방법을 적용하여 스포츠 현장의 문제를 어떻게 접근하고 있는지를 개괄하였다. 전통적으로 스포츠 통계는 선수와 팀 그리고 전략의 평가가 주를 이루었지만, 오늘날 스포츠통계는 경기의 잠재적, 외적 요인 등의 주제로 관심영역을 넓혀가고 있다. 그러나 국내에서는 경기내용의 기술적(descriptive) 분석이 주류를 이루고 있으며, 전문적 수준의 통계적 접근은 활발하지 못하고 있다. 현장과 자료의 특성을 고려하여 통계와 스포츠(체육)분야의 다양한 협동연구가 필요하다.

The purpose of this study was to investigate the effects of coach confidence on member satisfaction and perceived performance in throwers. The participants were 198 throwers who were competed in the 40th National Athletics Championship. To analyze the data, multiple regression was performed using SPSS 18.0 ver Windows. The results showed that coach confidence of throwers affected significantly on the athlete satisfaction(p<0.05). In other words, the subfactor of coach confidence such as integrity, ability, consistency, sacrifice, and openness affected the subfactor of player satisfaction such as technical analysis, teaching ability, and coaching qualification. And also, coach confidence of throwers affected significantly on the perceived performance(p<0.05). The subfactor of coach confidence such as integrity, ability, consistency, sacrifice, and openness affected the subfactor of player satisfaction such as victory will and skill exhibition. It was concluded that the coach confidence of throwers may affect player satisfaction and perceived performance.

기술발전에 따라 건설현장은 스마트 안전관리기술을 활용한 안전관리의 변화가 예고되고 있다. 중대재해처벌법 시행(22.1.27)이후 50인 이상 사망사고는87건(96명)으로 전년 동기109건(111명)대비22건(20.2%), 15명(13.5%)감소한 것으로 나타났다(국토교통부,2022). 반면에 단순비교지만 일본0.14%, 미국0.37%, 영국0.03%에 비해 한국의 재해율이 높으므로 다양한 안전관리활동의 과제가 남아 있다. 이에 아차사고 유형이 건설현장 특성간의 민감도모델 제시를 기반으로 근본적인 재해관리가 연구의 목적이다. 이를 이루기 위해 국토교통부의 아차사고 발굴데이터를 분석하여 유형을 분류하고, 공사기간, 공사규모, 신체부위 등의 요인간의 아차사고 민감성요인에 대하여 Bayesian Network를 이용하여 아차사고에 영향을 주는 모델링을 제시하고자 한다.

This paper presents an empirical analysis on the relationship between consumer sentiment and macro-economic indices by consumer's characteristics such as age, income and employment type. According to the empirical analysis based on the Consumer Sentiment Index(CSI) of the Bank of Korea and other macro-economic indices, the following study findings are presented. First, individual consumer sentiment depends not only on GDP growth, but also on other macro-economic conditions such as wage, employment, consumer and asset price, and debt burden. Second, the degree of importance of the macro-economic indices on determining individual consumer sentiment varies strongly according to consumers' characteristics. These findings reveal that the gap between consumer sentiment and GDP growth can largely be explained by considering the other macro-economic indices and consumer's characteristics.

The canonical correlation biplot is a 2-dimensional plot for graphically investigating the relationship between two sets of variables and the relationship between observations and variables in the canonical correlation analysis. Recently, Choi and Choi (2008) suggested a method for investigating the relationship between skill and competition score factors of KLPGA players using this biplot. Choi et al. (2010) used this biplot to analyze the player characteristic factors and competitive factors of tennis Grand Slam competition. Moreover, Huh (1999) provided a generalized canonical correlation analysis and biplot for more than three sets of variables. A Procrustes analysis is a useful tool for comparing shapes between configurations. This study will provide a method to investigate the relationship between physique, physical fitness and basic skill factors of tennis players in the Korea Tennis Association using a generalized canonical correlation biplot and Procrustes analysis.
