The purpose of this study was to prove a development and initial validation of the korean version of coach-athlete relationship maintenance scale that originated from the work of Rhind & Jowett(2012) in pro baseball. The items were then administered to 132 Participants(29 coaches and 103 athletes) completed the questionnaires of the coach-athlete relationship maintenance in First preliminary investigation. Maximum likelihood estimate was used to identify the latent underlying structure. In order to verify the validity of Korean version of coach-athlete relationship maintenance was administered to an independent sample of 273 coaches and athletes. Pro baseball coach-athlete relationship maintenance is consisted of six factors(25 items) with conflict management, motivational, preventative, openness/assurance, support, and social network. SPSS18.0 and AMOS16.0 were used to analyze the exploratory factor analysis, confirmatory factory analysis and internal consistency, test-retest with bootstrapping using of the data in this study. The results of the pro baseball coach-athlete relationship maintenance scale had six factors with 25 items, and each six factor was positively correlated. Overall, this study verified pro baseball coach-athlete relationship maintenance questionnaire. Thus, suggest that path of comparing the differences between the first division and farm team by using the test of the structural model invariance across the groups.

The purpose of this paper is to identify whether the national baseball squad made up of the best players may get the outstanding results in the international competitions or not. Using Data Envelopment Analysis, the relative efficiency of players in Korean Baseball Organization is estimated as performance measure, and compared with the efficiency scores of national squad members. The paper focuses on the proper choice of DEA model in a baseball setting, thereby selecting the BCC model with non-discretionary variable. Two input variables(plate appearances and stolen bases to enforce) and three output variables(runs, on-base plus slugging and stolen base percentage) are used to evaluate the efficiency of the baseball players. Results showed that 22 players among 97 players were classified as efficient and 8 players among 12 national squad members were as efficient. These findings indicate a potential for DEA to be a major part of the analytical approaches in evaluating the relative efficiency of players.

In this paper, we propose a method that merges and splits players in the MeanShift tracking framework. The MeanShift tracking moves the center of tracking window to the maximum probability location given the target probability distribution. This tracking method has been widely used for real-time tracking problems because of its fast processing speed. However, it hardly handles occlusions in multiple object tracking systems. Occlusions can be usually solved by applying data association methods. In this paper, we propose a method that can be applied before data association methods. The proposed method automatically merges and splits the overlapped players by adjusting the each player's tracking map. We have compared the tracking performance of the MeanSfhit tracking algorithm and the proposed method.

Purpose: To evaluate the aspect of occurrence and transition of the elbow injuries in baseball players from childhood to adult. Materials and Methods: We had a survey and took the simple X-ray from the anteroposterior view and the lateral view of both elbows for subjects of total 320 baseball players. - each of 80 players in elementary school, middle school, high school, and professional baseball players between January and December in 2004. Results: The region of pain and the bony changes in elbow were the most frequent in medial side from all the groups of players. Especially, hypertrophy of medial epicondyle were the most numerous. As baseball players got older, the radiological changes of elbow were increased. The bony changes were found out 52 cases (65%) of the elementary school players, 66 cases (82%) of the middle school players, 68 cases (85%) of the high school players and 70 cases (88%) of the professional players out of the total 320 baseball players. Conclusion: The bony changes of the elbow in baseball players got frequent as they were getting older and increased in comparison with past.

관람석에서 바비큐를 먹으며 경기를 보거나 좀더 가까이 선수들을 볼 수 있는 야구장. 탁 트인 구장으로 경기장 밖에서도 선수들과 관중들을 보면서 함께 즐길 수 있는 야구장. 야구팬들이라면 누구나 미국 메이저리그 야구장에서만 볼 수 있는 풍경을 국내에서도 볼 수 있기를 꿈꾸었을 것이다. 최근 그 꿈이 실현됐다. 바로 지난 3월 19일 시범경기 개막전을 치른 '대구삼성라이온즈파크' 야구장이다. 미국 메이저리그 필라델피아 필리스의 홈구장인 '시티즌스뱅크파크'의 모양을 벤치마킹한 '대구삼성라이온즈파크' 야구장은 국내 최초로 팔각형으로 설계돼 넓은 관람공간과 탁 트인 시야가 특징이다. 지난 2012년 12월 첫 삽을 뜬 후 40여 개월 만에 총사업비 1,666억원을 투입해 지난 3월 완공되었다. '대구삼성라이온즈파크'는 야구 명문인 대구 경북의 자긍심과 함께 대구의 새로운 랜드마크로 자리매김하며 도시브랜드 향상과 더불어 시민들의 놀이, 휴식공간, 나아가 전국의 야구팬들이 찾고 싶은 관광 명소가 될 것으로 기대를 모으고 있다. 대구광역시 수성구 연호동에 위치한 대구삼성라이온즈파크는 (주)대우건설컨소시엄이 종합 시공을, (주)백산이엔씨가 냉 난방, 위생, 소방 등 기계설비를 시공했다. 본지는 준공 후 마무리 작업이 한창인 지난 3월 중순 대구삼성라이온즈 파크 현장에서 (주)대우건설 금현철 현장소장과 (주)백산이엔씨(대표 김주환) 김재화 현장소장을 만났다.

The purpose of this study was to investigate the effect of prop exercise convergence using vibration on batting speed and batting accuracy in elementary school baseball players. Three times a week for six weeks. The vibration exercise experimental group and the control group were divided into each twenty members. The experimental group performed vibration convergence prop exercise, and the control group performed general exercise. Batting speed and Batting accuracy were measured. The experimental and control groups showed significant differences in the groups of batting speed before and after intervention. There was significant difference between the batting accuracy in the comparison between the experimental group and the control group. Prop convergence vibration exercise may help to improve the batting speed and batting accuracy of elementary school baseball players. In the future, adult and sport injury patient are needed.
