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.

1997년말 발생한 외환위기 이후 불확실성의 증대로 시계열모형을 이용한 경제예측에 한계가 노정되고 있다. 이를 극복하기 위하여 경제주체의 기대(expectation)를 파악할수 있는 기업경기실사지수를 경제예측에 도입할 필요가 있다. 본고에서는 기업경기실사지수를 이용한 모형과 시계열모형을 추정하고 이들을 예측력 측면에서 비교, 분석해보았다. 분석결과 불확실성이 높았던 외환위기이후 기간에는 기업경기실사지수를 이용한 모형이 시계열모형보다 예측력면에서 우수한 것으로 나타났다.

In recent years, women's monetary rewards in golf increased and their performances have improved significantly compared to other sports. Sports marketing has become more active in Asia and the number of Korean players in LPGA with good scores are increasing. For these reasons, golf is becoming increasingly popular. The prize money is higher than in other sports and the economic benefits are increasing due to the financial incentives such as sponsorships. Many of these prospects actively affect women's golf. Certain rookies continue to increase and their performances improve day by day. In this study, I analyze the changes in performance over time of last 5 years from 2009 using growth curve analysis. According to the results of analysis, driving distance and average putting skills developed but green in regulation decreased.

본 연구는 마케팅성과에 대한 Kotler의 접근법을 원용하여 한국의 대표적인 제조기업과 서비스 기업들의 마케팅 성과에 영향을 주는 요인들을 발견하고 경영 시사점을 제시하기 위한 모델을 개발하였다. 제조 분야에서 10개 기업, 서비스 분야에서 9개 기업을 각각 선정하여 전체 19개 기업의 마케팅 성과의 수준을 평가해 보았다. 확인요인분석 결과 제조기업의 마케팅 성과요인으로는 마케팅 인력, 마케팅 조직, 마케팅 전략이 추출되었고 서비스기업의 요인으로는 마케팅 인력, 마케팅 정보, 고객지향성, 마케팅 전략이 추출되었다. 5개의 마케팅성과요인과 제품력, 유통력, 판촉력, 가격력으로 구성된 마케팅역량, 그리고 고객만족 간의 관계를 규명할 목적으로 구조방정식모형을 구축하고 관계들에 관한 가설들을 검증하였다. 요인분석결과 제조기업은 마케팅인력, 마케팅 조직, 마케팅 전략의 세 요인이 유의한 요인으로 나타났으나, 서비스 기업에서는 마케팅 인력, 마케팅 정보, 고객지향성, 마케팅 전략의 4요인이 유의하게 나타났다. 각 요인의 평균치 분석결과, 서비스기업이 제조기업에 비해 마케팅성과 영향요인, 마케팅역량과 고객만족에서 모두 우세하게 나타났다.

The purpose of this study is to identify the mediating effect of self-efficacy in the relationship between the leadership style of badminton life sports leaders and the performance of club members. A total of 600 badminton club members were invited to participate and 593 were selected for this study. For data analysis, mediating effects were verified through frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, multiple regression analysis, and hierarchical regression analysis. For result section, first, it was found that training instruction behavior, authoritative behavior, and social behavior, which are sub-factors of the leader leadership type, have a positive effect on performance(p<.05). Second, it was found that training instruction behavior, which is a sub-factor of leader leadership type, had a positive effect on self-efficacy(p<.01), and that authoritarian behavior had a negative effect on self-efficacy(p<.01). Third, the mediating effect of self-efficacy was found indirectly in the relationship between leader leadership and performance(p<.001). Based on these results, it is judged that it will be easier to build a more effective training system if the direction for the leadership and guidance type of life sports is set by reflecting the needs of the participants.

When it comes to explaining the relationship between inventory investment and business fluctuations, the production smoothing theory and the stock-out avoidance theory take contradictory stances. Decision-making related to inventory investments of corporations is thought to be influenced by both motives, but the relative sizes or directions of their respective influences can differ depending upon the phase of the business cycle. Against this backdrop, this paper differs from existing studies in that it theoretically tests the relative significances of the production smoothing and stock-out avoidance motives in the inventory investment dynamics, while placing its analytical focus on determining the existence and patterns of the asymmetric dynamics of inventory investment over the business cycle phases. To this end this paper sets up a non-linear model that is expanded from the existing linear inventory investment model, and checks whether its predictive power is better than that of the existing model. The results of analysis confirm the nature of the asymmetric dynamics of inventory investment over the business cycle phases. A stock-out avoidance motive appears but there is no significant production smoothing motive in boom times. In downturns, in contrast, the stock-out avoidance motive is insignificant, but a quality of asymmetric dynamics in which changes in inventory cause the deepening of recessions, due to the non-convexity of production costs proposed by Ramey (1991), is detected. This paper confirms that a model considering the asymmetric dynamics of inventory investment can have better predictive power than one that does not consider it, through within-sample and out-of-sample predictions and various predictive power tests. These research results are expected to be useful for economic forecasting, through their enhancement of the understandings of the inventory investment dynamics and of the nature of its business cycle destabilization.

The purpose of this study is to provide basic information to develop a game strategy plan of a team in a future by identifying the patterns of attack and pass of national men's professional volleyball teams and extracting core key words related with volleyball game performance to evaluate game performance using 'social network analysis' and 'text mining'. As for the analysis result of 'social network analysis' with the whole data, group '0' (6 players) and group '1' (11 players) were partitioned. A point of view the degree centrality and betweenness centrality in 'social network analysis' results, we can know that the group '1' more active game performance than the group '0'. The significant result for two group (win and loss) obtained by 'text mining' according to two groups ('0' and '1') obtained by 'social network analysis' showed significant difference (p-value: 0.001). As for clustering of each network, group '0' had the tendency to score points through set player D and E. In group '1', the player K had the tendency to fail if he attack through 'dig'; players C and D have a good performance through 'set' play.

This paper establishes the empirical model based on Hall's(1990) and Basu' s(1996) models, estimates the five types of productivity in the medical service industry over the period 1975:1-2010:4, and analyzes the cyclicality of measured productivities and their correlations with the industrial real wage. The empirical results are summarized as the followings. First, there proved to be substantial market power in pricing and returns to scale in production for the medical service industry. Second, the three types of productivity among 5 types showed to be procyclical. Third, the average labor productivity, the original Solow residual, and the cost-based Solow residual are expected to provide reasonable indexes in analyzing the relationship between productivity and real wage.

The purpose of this study was to analyze the perceptions of disabled sports that were reported the newspapers using semantic network analysis method. for this purpose, 745 news articles were selected from 21 source in Naver news searching engine. The main keyword for searching on newspapers was 'disabled sports'. Krkwic software was used for keyword cleansing and co-occurrence of text to text matrix in frequencies. Centrality indices that are degree, between and eigenvector, were used to analyze the perceptions of disabled sports from Netminer 4.0 for semantic network analysis. The conclusion of overall results from this study are follows; First, the core keyword of disabled sports in newspapers are 'impression', 'challenge', 'festival', 'dream' and hope. And there is different concepts of cognition among types of disability. Second, there are two elements on the perceptions of disabled sports from reported newspapers; sports performance and emotional. Specifically, main stream of keyword were 'Paralympics' and 'Special Olympics' on sports performance element and 'impressive' and 'challenge' in emotion element.
