To realize various opportunities to choose careers for adolescent sports players, first, it is necessary to help them choose a job suitable for each student's aptitude. In reality, adolescent sports players absolutely have insufficient time for choosing various careers unlike general adolescents and realizing them. Thus, differentiated and specialized convergence learning materials are needed by each job cluster suitable for adolescent sports players' aptitude. The learning materials, specialized for these individual job clusters are a method to show a great effect on education with investing the minimum time, so they have a high value for utilization as necessary learning information for the realization of various opportunities to choose various careers for adolescent sports players.

In football simulation games, it is very important for the interest of the game to make the stats of the football players close to reality. As the management concept is introduced to the sports simulation game, when the user plays the game for a long time, the existing player character retires. Therefore, the game creates the environment of the game by creating a new player in the game. In this study, we propose a method to create a new player character by using genetic algorithm to have the optimal ability similar to existing players. We compare and evaluate the player character with the existing random generation method, the correction random method and the proposed algorithm, and verify the validity of the proposed method.

Prediction of energy absorption for bow structure is important for a design of protective structures against collision. For the crushing behaviour of basic element of energy absorption, the plastic mechanism method is applied. The ship's crushing strength of bow section is obtained by summing the energy dissipated in all individual elements. The theoretical predictions are compared with experimental results for ship's bow models published with experimental results for ship's bow models published in the references, and it is observed that the present prediction method of crushing strength correlates well with the experimental results.

Purpose: To evaluate the ultrasonographic (US) findings in both shoulders of asymptomatic high school baseball players and compare with healthy control. Materials and Methods: 42 individuals (age: $7.6{\pm}1.2$ years) participated in this study. We recruited two groups of high school male baseball players, 14 pitchers and 18 fielders without shoulder pain for recent 6 months as well as one control group of 10 untrained healthy high school students who were age-matched. Ultrasound measurements of thickness of the biceps and supraspinatus tendon and acromio-humral distance (AHD) at $0^{\circ}$ abduction were taken in dominant and nondominant shoulders. Results: On US examination, subacromial bursa effusion was observed in 7 of the dominant shoulders and in 2 of the nondominant shoulder of 32 baseball players and in none of the asymptomatic controls. The thickness of the biceps and supraspinatus tendons and AHD in both shoulders were significantly greater in the baseball players than in the controls (p<0.05). We also found that the biceps and supraspinatus tendon thickness and AHD of the dominant shoulder were significantly greater than the non-dominant shoulder in baseball players (p<0.05), but there were no differences between pitchers and fielders and between healthy controls. Conclusion: Subacromial effusion could be found even in the asymptomatic stage and the thickness of the biceps and supraspinatus tendons and AHD were significantly greater in the baseball players than in the healthy controls. Our data is useful reference guide for the ultrasonographic diagnosis of shoulder pathologies occurring in high school baseball players.

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 study was to investigate the structural relationships among self-leadership, self-management, and self-confidence of golf players. In order to accomplish the purpose of this study, 447 of them were sampled through the convenience sampling. The instruments for data collection were Self-Leadership Questionnaire, Self-Management Scale1, and Sport Confidence Questionnaire. Collected data were put to exploratory factor analysis and correlation analysis, using the SPSS 18.0 program and to confirmatory factor analysis and structural equation model(SEM), using the AMOS 18.0 program. The results were as follows : First, self-leadership had positive effects on self-management, Second self-leadership had positive effects on sport confidence, Third, self-management had positive effects on sport confidence, Forth, the unstandardized path coefficient among self-leadership, self-management and sport confidence in the men was no different from that in the women.

This study was analyzed using Giorgi (1985)'s phenomenological research method to find the essential meaning of the strengths inherent in the experience of national players. The research participants selected the final six athletes who wanted to participate in the national team's individual and team events using the Purposeful sampling method. In-depth interviews were conducted from September to December 2019, and 90 to 180 minutes were conducted once and two in-depth interviews were conducted for each athletes. As a result, categories were derived from 17 sub-factors, 5 factors, and 5 factors were found to make good habits, make my own weapons, think positively, simplify and maintain good condition. The five factors shown in the results are used as strengths when they are voluntarily done, and these strengths create a chance and vitality for players to truly like their sport. These character strengths are expected to be used as positive information for players' development of positive psychology programs and psychological skills training.

Purpose: To estimate the prevalence and incidence of patellar tendinitis, to discover the patellar tendinitis in top level male volley ball players. Materials and Methods: Thirteen members of the male adult volleyball players were included in this study. From history and physical examination, 3 of the 13 players had patellar tendon pain associated with activity and were diagnosed as patellar tendinitis at the time of the study. Investigators were blinded about the injury status of the players. For all players, data such as age, volleyball experience, amount of training and competition hours were recorded. Results: Of the thirteen cases, two spikers complained pain on the lower pole of the patella, one setter on the upper pole. Conclusion: This findings suggest that patellar tendinitis in the volleyball players are influenced by the amount of the practice and their position. In most cases, the supervised control of the practice will reduce the overuse injuries in the volleyball players.
