The purpose of this research is to minimize the conflicts in the course of negotiating the annual salary between a professional basketball team and a player and to furnish basic data as intermediate variables to offer fans amusement, players qualitative plays, and teams the creation of images. The objects of this research are professional basketball players participating in the 2001-2002 season and 93 players who settle their annual salaries of the 2002-2003 season. I investigate the data using SPSS 11.0, a software for statistics. The results of this research are as follows: 1) As a result of investigating basic data, by using 6 variables(TFS, ID, CARE, P2, TUOV, WOFT), I can account for 85 percent of all the annual salaries, but can't explain the basic assumption of the recurrence analysis. 2) In order to settle problems, I perform the log transformation of the subordinate variables, and assume a model to explain about 85 percent with 4 variables(TUOV, CARE, TFS, G) satisfying all the basic assumptions.

This study is executed to examine closely the effect that bodybuilder's taking protein supplement affects muscular strength and blood constituent after weight training of eight weeks. They are randomly assigned with two groups that experimental group of 10 ones who execute weight training with taking pretein supplement and control group of 10 ones who just do weight training and weight, fat rating of body(%), muscular part. 1-RM and the change of blood constituent are analyzed according to programs of eight weeks. The results are as following: 1. Weight significantly increased before and after training in experimental group but there is no statistic significance though control group did a little bit before and after training. In the rating of body fat(%), both groups didn't show significant difference. 2. Experimental group and control one didn't show significant increase of upper arm's muschlar(left and right) and thigh muschlar part(left and right) but it's increasing rate was a little high in chest part in the change of muscular part 3. The cases of bench press, squat, dead-lift, shoulder press and barbell curl showed significant increase before and after training in both experimental and control group in the change of 1-RM. And experimental group increased a little bit more about 1RM than control group. 4. The cases of total-protein, creatine, Uric acid, and total-cholesterol significantly decreased before and after training in both groups in the change of blood constituent. BUN and CPK didn't show signifiant decrease or increase in experimental group and control group before and after training. Seeing above mentioned results, experimental group with protein supplement was efficient as compared with control group in weight. But the rating of body fat, muscular part, muscular strength and blood didn't have significant difference. Through these results it is considered that taking the protein supplement can't affect measurement variables in training of eight weeks, somewhat much protein injection and long period and intensified weight training than short one is necessary under the condition which there is a skill of experimental group and control group to examine the improvement of muscular fleshiness and the change of blood constituent.

This study examines the relations between organizational environment and business strategy and the effects of fitness on the firm performance. The data gathered from small-medium enterprises located in Gwangju industrial complexes. The organizational environment was classified into three types: dynamism, heterogeneity, and hostility. The business strategy was classified as prospector, analyzer, and defender. The fitness was conceptualized as moderation and calculated as index. sales growth, net income growth, market share, return on investment, and liquidity are used as financial performance measures. New product development, technological innovation, and employee's satisfaction are used as non-financial performance measures. Findings of this study are summarized as follows: (1)Dynamism was significantly and negatively related to defender. (2)Hostility was significantly and positively related to defender. (3)Heterogeneity was significantly and positively associated with prospector, analyzer, and defender. (4)The fitness between dynamism and business strategy had significant and positive effect on non-financial performance. (5)The fitness between hostility and business strategy had significant and positive effect on financial performance. (6)The fitness between heterogeneity and business strategy had significant and positive effect on both of financial and non-financial performance. The academic and practical implications of these findings are discussed for researchers and practitioners. 본 연구에서는 중소기업의 환경과 전략의 적합이 성과에 미치는 영향을 분석하기 위해 선행연구들의 고찰을 통해 환경과 전략의 관계를 도출하고 적합을 조정으로 개념화하여 성과와의 관계를 설정한 후, 광주지역의 중소기업을 대상으로 조사 분석하였다. 연구결과를 살펴보면, 환경의 역동성은 방어전략과 부(-)의 관계가 있었고, 환경의 적대성은 방어전략과 정(+)의 관계가 있었으며, 환경의 이질성은 혁신, 분석 및 방어전략 모두와 정(+)의 관계가 확인되었다. 한편, 역동성과 전략의 적합은 비재무성과에 긍정적인 영향을 미쳤고, 적대성과 전략의 적합은 재무성과에 긍정적인 영향을 미쳤으며, 이질성과 전략의 적합은 재무성과와 비재무성과 모두에 긍정적인 영향을 미치는 것으로 나타났다. 이러한 연구결과는 광주지역의 중소기업에 있어서 환경과 전략의 적합이 높을수록 기업의 성과가 더 좋아짐을 시사하고 있다.

The purpose of this study was to investigate by meta analysis in collecting research references whether exercise intervention affects bone density in domestic studies. Collecting total 22 references(60 researches) showed below results. A bone density variation of Femur neck appeared as EStotal (Total Effect Size) = 0.12 from total 27 researches, and the bone density increased 0.02 g/cm² from average 0.83 g/cm² of before exercising to average 0.85 g/cm² of after exercising. SE (Sampling Error)is 0.087 which showed resonable results of samples and Q(homogeneous quantity) is 5.79 (p >.01) which showed homogeneous of samples. A bone density variation of Lumber appeared as EStotal = 0.15 from total 33 researches, and the bone density increased 0.03 g/cm² from average 0.99 g/cm² of before exercising to average 1.02 g/cm² of after exercising. SE is 0.076 which showed resonable results of samples and Q is 22.36 (p >.05) which showed homogeneous of samples. The average ES value of 2 measurement region (Femur neck, Lumber)is 0.135. These results indicate that exercises did not nearly affect improvement in bone density.

This study focuses on the global selling of domestic products which are made by regional firms with a low level of brand awareness, through cross-border electronic commerce (EC). Cental and local governments in Korea attempt to facilitate the global selling of agricultural and marine products which have the potential to attract global customers. Given that cross-border EC in China is expanding greatly, this study tries to elicit effective ways of promoting and selling the products to global customers. More specifically, this study provides insights by analyzing the cases of the Chinese Global Selling Support Project which is implemented by the collaboration of a local government and a local university, including four areas such as the operation of an antenna shop in China and the survey on its visitors, the establishment of online shopping malls, live-streaming commerce based on WeChat, and local events on the spot. The main findings are as follows. Firstly, the survey on visitors of the antenna shop shows that regional firms’ products need to improve the credibility, satisfaction, and purchase intentions of the products. Secondly, online shopping malls and live streaming commerce based on WeChat has the potential to expose the products to countless Chinese consumers in a short time and to grasp their real-time responses. Finally, local events on the spot confirms the possibility of the global selling when sufficient information on the products are delivered to Chinese consumers. Further discussion and implications of the findings are provided.
