[Purpose] The purpose of this study was to develop a psychic energy management scale that construct a concept and based on extracted contents of structural validity and reliability of university athlete psychic energy management inventory. [Methods] To develop the scale, the researches were completed <research ⅰ; constructing sub-factors of Psychological Energy Management, ⅱ; developing scales of psychic energy management, ⅲ; verifying validity of psychic energy management>. The results shown are a follows. [Results] The psychic energy management inventory contents of the university athlete were categorized into five categories ; team energy, game energy, environment energy, leisure energy and body energy. Through statistical procedures and factor analysis, the psychic energy management inventory was developed with 4 factors 18 items (coach energy 4 question items, game/environment energy 6 question items, colleague energy 4 question items, body energy 4 question items). [Conclusion] Convergent validity and discriminant validity was demonstrated through the external validity, the multi-group analysis confirmed the structural equivalence of the scale between the school grades. [목적] 본 연구의 목적은 대학운동선수의 심리적 에너지 관리에 대한 개념을 구축하고 추출된 내용을 근거로 타당성과 신뢰성이 입증된 심리적 에너지 관리 척도를 개발하는데 있다. [방법] 척도 개발을 위해 <연구ⅰ, 심리적 에너지 관리의 하위요인 구성 및 개념정립>, <연구ⅱ, 심리적 에너지 관리의 척도 개발>, <연구ⅲ, 심리적 에너지 관리의 타당도 검증>의 과정으로 진행되었다. [결과] 첫째, 대학운동선수가 생각하는 심리적 에너지 관리 척도의 내용은 팀 에너지, 경기 에너지, 환경 에너지, 여가 에너지, 신체 에너지의 5개 영역으로 범주화 되었다. 둘째, 통계적 절차와 요인분석을 통해 심리적 에너지 관리 척도는 4요인 18문항으로 추출되어 최종 검사지가 개발되었다. [결론] 최종 개발된 척도를 대상으로 수렴타당도와 변별타당도를 통해 외적타당도를 입증하였으며, 다집단 분석을 통해 학년 간 심리적 에너지 관리 척도의 구조적 동일성을 확인하였다.

The objective of this study was to identify the relationship between exercise needs and exercise self-schema of students participating in university physical activity classes. The participants consisted of 243 students of A university located in Gangwon-do, who were participating in university physical activity classes. The collected data was statistically processed using SPSS 18.0 and AMOS 20.0. In order to verify the reliability of the survey questionnaires, Cronbach’s α value was calculated, and confirmatory factor analysis and exploratory factor analysis were performed for the validity of the survey questionnaires. To obtain information of personality traits, frequency analysis was implemented. The average and standard deviation of measurement variables were calculated and correlation analysis of the measurement variables was carried out. To verify the relationship between exercise needs and exercise self-schema, a multiple regression analysis was performed. The result showed that, firstly, there was a partially statistics significant difference between exercise needs and exercise self-schema according to their demographic variables. Moreover, there were positive influence on correlations among their exercise needs and exercise self-schema. Secondly, a positive effect of degree of exercise needs on exercise self-schema was found.

The dynamic responses of a PSC bridge for automated guide-way transit system are investigated by analytical approach of bridge-vehicle interaction. In this study, the dynamic responses, concerned with a spall on the surface of bridge are emphasized. A simply supported pre-stressed concrete bridge is adopted as a numerical example. Dynamics of three-dimensional dynamic interaction system between bridges and vehicles is considered in this study. The FE method and modal analysis is used for modeling a bridge for dynamic response analysis. An AGT vehicle is idealized as a model with 11DOFs including lateral motion. It was found that the dynamic responses of bridge can be affected by a spall of surface. Especially, the vibrations are increased much more when a spall is exist.
