On-The-Fly (OTF) observation method is developed for the efficient use of 6 M radio telescope at Seoul Radio Astronomy Observatory (SRAO). This technique, in which data and information of antenna position are recorded synchronously while driving a telescope regularly and rapidly across a field, provides more efficient use of telescope time and better calibration of the acquired data than the traditional point-to-point observation method does. For the realization of the method, we (1) added RT-Linux modules to the existing operating system, (2) replaced digital voltmeter with voltage-to-frequency converter, and (3) modified many SRAO observation programs. By observing Moon and G78.2+2.7 using this method and comparing them with previous observations, we verify the successful operation and efficiency of the OTF observation mode.

목적: 본 연구에서는 스포츠 팀 구성원들의 상호작용을 측정하기 위한 측정도구의 개발과 개발된 측정도구의 타당성을 검증함으로써 스포츠 팀 경기력 향상을 위한 과학적이고 객관적인 정보를 제공하는데 목적이 있다. 방법: 연구의 대상은 중, 고등학교 단체종목 선수(축구, 농구, 배구)를 총 635명을 대상으로 연구를 실시하였다. 구체적으로 탐색적 요인분석 238명, 확인적 요인분석 및 타당도 검증에 352명의 활용하였다. 수집된 자료는 탐색적 요인분석, 확인적 요인분석, 다집단 확인적 요인분석 등을 실시하였다. 결과: 탐색적 요인분석의 결과 최종적으로 스포츠 팀 상호작용 척도는 다차원으로 구성된 총 5요인, 25문항으로 개발되었다. 타당성 검증 결과 5요인 25문항으로 구성된 스포츠 팀 상호작용 척도가 구조적으로 비교적 적합한 모형인 것으로 나타났다. 또한 개념타당도, 교차타당도, 수렴타당도 모두 제시된 기준치를 충족하는 결과를 보였다.

Purpose: Team cohesion and team work are the usual components for explanation of team performance in Korean sport psychological field which is somewhat limited. So for the purpose of systematic and effective explanation of performance, this study was aimed to investigate concept of integral interaction among team members. Methods: Subjects of study were 255 middle and high schools elite players(soccer, basketball and volleyball). Results were extracted from often-ended questionnaires. Data were inductively analyzed through a meeting of experts. Results: With regard to coach interaction, players of team sports represented assimilation, communication and role, and represented assimilation, communication and dependence in regard to colleague player interaction. Conclusion: The present study has contributed to existing literature by providing basic resources to further develop the questionnaires in relation to team sports interaction. Furthermore, the findings from this research may shed light on the scientific and objective knowledge in performance improvement of team sports.

The purpose of this study was to investigate the mediating effect of grades, positions, and match results in the causal relationships between achievement-goal orientation and sport flow among middle and high school soccer players. The total data of 448 copies were collected from middle and high school soccer teams while 405 copies were accepted for final analysis without 43, and multi-group confirmatory factor analysis was conducted to the data. The result of latent mean analysis showed that middle school players had significantly higher mean in sense of control of sport flow and transformation of time, and defenders showed significantly higher than offenders in ego orientation and transformation of time, while winning group achieved significantly higher than losing group in all factors except ecstasy. Also multi-group analysis showed that achievement-goal orientation had significant effect on sport flow in middle and high school players, and middle school players had more powerful effect than high school players. Meanwhile, the achievement-goal orientation affected significantly on sport flow in offenders and defenders, and ego orientation of offenders affects on sport flow. task orientation of winning and losing groups had significant effect on sport flow, and ego orientation of winning group showed significant effect on sport flow.
