여고생의 체육교사신뢰와 체육학습의욕 및 체육수업만족의 구조분석
김승환,조미혜 한국여성체육학회 2020 한국여성체육학회지 Vol.34 No.2
The purpose of this study is to investigate the structural relationship among the physical education teacher-trust, the physical education learning motivation, and the satisfaction of physical education class in high school female students. In order to achieve this purpose, a total 337 questionnaires were used the as final valid sample for high school female students in the Incheon area using the convenience sampling method. For data processing, SPSS ver 18.0 and AMOS 18.0 program were used to verify the fit of the entire model and then individual hypotheses were verified. The result are as follows. First, the physical education teacher-trust for high school female students had statistically positive effect on the satisfaction of physical education class. Second, the physical education teacher-trust had statistically positive effect on the physical education learning motivation. Third, the physical education learning motivation had statistically positive effect on the satisfaction of physical education class. Therefore, in order to increase the satisfaction of physical education class, it was found that trust in teachers and the physical education learning motivation are very important factors. And teachers need to build a relationship of intimacy and trust through ongoing interaction with students. In the future study, research on the development of specific teaching strategies and teaching programs in which high school female students can trust the PE teacher should be conducted. 이 연구의 목적은 여고생의 체육교사신뢰와 체육학습의욕 및 체육수업만족의 구조적 관계를 규명하는 것이다. 이를 위해 편의표본추출법을 사용하여 인천지역의 여자고등학교 학생을 대상으로 설문을 진행하였고총 337부를 최종 유효 표본으로 사용하였다. 자료처리는 SPSS 18.0과 AMOS 18.0 프로그램을 활용하여 전체모형의 적합도를 확인하고 각각의 가설들을 검증하였다. 본 연구의 결과는 다음과 같다. 첫째, 여고생의 체육교사신뢰는 체육수업만족에 유의한 정(+)적인 영향을 미쳤다. 둘째, 여고생의 체육교사신뢰는 체육학습의욕에 유의한 정(+)적인 영향을 미쳤다. 셋째, 여고생의 체육학습의욕은 체육수업만족에 유의한 정(+)적인 영향을 미쳤다. 따라서 여고생의 체육수업만족도를 높이기 위해서는 교사에 대한 신뢰와 체육학습의욕이 매우중요한 요인이며, 교사는 학생과의 지속적인 상호작용을 통해 친밀함과 신뢰의 관계를 형성해야 하는 것으로 나타났다. 마지막으로 후속연구에서는 여고생들이 체육교사를 신뢰할 수 있는 구체적인 교수전략과 수업프로그램 개발 연구가 진행되어야 할 것이다.

입자크기분포 설정 및 멀티스레딩을 통한 소외사고영향분석 최적화 타당성 평가
김승환,김성엽 한국안전학회 2024 한국안전학회지 Vol.39 No.1
The demand for mass calculation of offsite consequence analysis to conduct exhaustive single-unit or multi-unit Level 3 PSA is increasing. In order to perform efficient offsite consequence analyses, the Korea Atomic Energy Research Institute is conducting model optimization studies to minimize the analysis time while maintaining the accuracy of the results. A previous study developed a model optimization method using efficient plume segmentation and verified its effectiveness. In this study, we investigated the possibility of optimizing the model through particle size distribution setting by checking the reduction in analysis time and deviation of the results. Our findings indicate that particle size distribution setting affects the results, but its effect on analysis time is insignificant. Therefore, it is advantageous to set the particle size distribution as fine as possible. Furthermore, we evaluated the effect of multithreading and confirmed its efficiency. Future optimization studies should be conducted on various input factors of offsite consequence analysis, such as spatial grid settings.

In case of the slowly disintegrating tablets such as enzyme preparations, disintegration time (DT) may be the important factor in formulating those preparations. The effects of tablet hardness, lubricants and disintegrants on DT were investigated in this approach. Disintegration time was significantly affected by disintegrants, moderately by lubricants, but not by tablet hardness. The effect was in the order of magnesium stearate >talc, PEG, sodium benzoate in case of lubricants, and of Ac-Di-Sol>LHPC > Primogel > Kollidon in case of disintegrants. Because lubricants and disintegrants influenced the tablet hardness and DT profile showed complicated pattern, it should be remembered that all factors mentioned above should be simultaneously considered in the formulation of enzyme tablets.

골프참여자의 관여정도에 따른 운동중독현상이 심리적 행복감에 미치는 영향
김승환 한국골프학회 2016 골프연구 Vol.10 No.2
본 연구는 실내연습장과 실외연습장에서 골프를 참여하고 있는 사람을 모집단으로 설정하였고, G지역 4곳의 골프장에서 각 70부씩 총 280부의 설문지를 받아 총 280부를 실증자료에 사용하였다. 또한 설문지의 타당도와 신뢰도 검사를 위해 SPSS 22.0을 활용해 탐색적 요인분석과 신뢰도 분석을 실시하였으며, 각 변인의 상관성과 다중공선성을 검증하기 위해 상관관계분석을 실시하였고, 가설검증의 인과관계 분석을 위해 다중회귀분석을 실시하여다음과 같은 연구결과를 도출하였다. 첫째, 골프 참여자 운동중독은 심리적 행복감의 하위요인인 자아수용에 영향을 미치는 것으로 나타났다. 둘째, 골프 참여자 운동중독은 심리적 행복감의 하위요인인 몰입감에 영향을 미치는 것으로 나타났다. 셋째, 골프 참여자 운동중독은 심리적 행복감의 하위요인인 만족감에 영향을 미치는 것으로나타났다. This Study designed to examine the effects of exercise dependence on psychological happiness in golf participants with involvement. The participants were selected by systematic stratifies cluster random sampling method. They are composed 280 adults who had been participating in golf practice in golf ranges. the Questionnaire was given to 270 members of golf participants and engaging in the range activity from March 2016 to April 2016. After collecting the questionnaires, I exclude 12 unreliable questionnaires which were incomplete, incorrectly marked or double marked, and used 270 questionnaires for the study. The data processing was done through frequency analysis, dscriptive statistics, correlation analysis, and multiple regression analysis by using SPSS WIN ver 22.0. The conclusion of this research was as follows: First, The Exercise dependence factor had a effect on self acceptance of psychological happiness in golf participants with involvement. Second, The Enjoyment factor had a effect on immersion of psychological happiness in golf participants with involvement. Third, The Enjoyment factor had a effect on satisfaction of psychological happiness in golf participants with involvement.
