This study aims to examine and identify the effects of structural relationship among vitality, social support and quality of life for older adults who participate in physical activity. To achieve the aim of the study, a total of 313 questionnaires were collected from older adults. The collected data were analyzed by SPSS 21 and AMOS 21.0. Validity test were conducted. Descriptive statistical analysis, frequency analysis, reliability analysis, confirmatory factor analysis, correlation analysis, structural equation model analysis and bootstrapping method were used to examine the mediation effect. The results of this study are as follows. First, vitality had a positive relationship with social support. Second, vitality did not have a significant relationship with quality of life. Third, social support had a significant relationship with quality of life. Fourth, social support had a mediating effect between vitality and quality of life. In conclusion, social support is the most important factor in improving the quality of life for older adults.

This study aims to examine effects of mixed martial arts(MMA) trainees` self-esteem on their stress and mental health. To this end, 330 MMA trainees in MMA gymnasiums were selected as study subjects but a survey of 302 among them was only conducted. The collected data carried out factor analysis and reliability analysis to verify construct validity and to analyze the result, descriptive statistics, correlation analysis and multiple regression analysis were conducted. As the result, effects of MMA trainees` self-esteem on stress were negative self-esteem, followed by positive self-esteem. Effects of MMA trainees` self-esteem on emotional health showed that fear/anxiety, depression, somatization, and compulsion had impact on both positive and negative self-esteem.

The purpose of this study was to present the models for classifying the wrist X-ray images by types and for segmenting the radius automatically in each image using deep learning and to verify the learned models. The data were a total of 904 wrist X-rays with the distal radius fracture, consisting of 472 anteroposterior (AP) and 432 lateral images. The learning model was the ResNet50 model for AP/lateral image classification, and the U-Net model for segmentation of the radius. In the model for AP/lateral image classification, 100.0% was showed in precision, recall, and F1 score and area under curve (AUC) was 1.0. The model for segmentation of the radius showed an accuracy of 99.46%, a sensitivity of 89.68%, a specificity of 99.72%, and a Dice similarity coefficient of 90.05% in AP images and an accuracy of 99.37%, a sensitivity of 88.65%, a specificity of 99.69%, and a Dice similarity coefficient of 86.05% in lateral images. The model for AP/lateral classification and the segmentation model of the radius learned through deep learning showed favorable performances to expect clinical application.

The purpose of the study is to investigate the influences of form of participation in screen golf of workers on interpersonal orientation and job stress. To meet this research purpose, 280 workers who are using screen golf was selected as subject, and data of 264 workers were used for research in quality. As for the collected materials, factorial analysis and reliability analysis were carried out, and for result analysis, correlation analysis, multiple variance analysis, and multiple regression analysis were carried out. As results of analysis, as for the difference of interpersonal orientation according to form of participation in screen golf of workers, there was difference in tendency of social relation according to participation frequency and was tendency of role according to par score of screen golf. The difference of job stress according to form of participation in screen golf was not significant statistically. As for the influence of interpersonal orientation of workers who are participating in screen golf on job stress, it was appeared that all of physical stress, sense of oppression due to job as it is, and mental stress have influence on tendency of expression, tendency of social relation has influence on mental stress and tendency of role has influence on sense of oppression due to job as it is.

본 연구의 목적은 사회생태학적 관점에서 사회적 환경과 물리적 환경 변인들이 어떻게 운동 자기-도식에 영향을 미치는지 알아보고, 신체활동증진 개입전략의 기초적인 자료를 제공하는데 목적이 있다. 방법: 경기도에서 개최된 생활체육대회 이벤트에 참여한 50대 남성 238명이 본 연구의 최종분석에 사용되었다. 운동 자기-도식, 사회적 환경, 물리적 환경, 운동의도 질문지가 사용되었다. 확인적 요인분석, 신뢰도분석, 상관관계분석, 구조방정식 모형분석이 본 연구의 분석에 사용되었다. 결과: 첫째, 사회적 환경과 물리적 환경 변인 모두 운동 자기-도식에 긍정적 영향을 미쳤다. 둘째, 운동 자기-도식과 물리적 환경은 운동의도에 긍정적 영향을 미쳤다. 그러나 사회적 환경은 운동의도에 직접적인 영향을 미치지 않았다. 결론: 사회적 환경과 물리적 환경이 운동 자기-도식에 긍정적 영향을 미친다는 결과를 바탕으로 환경적 요인들은 운동행동에 도움을 줄 수 있다는 것을 확인하였다. 더불어, 신체활동증진 프로그램에 대한 많은 다양한 연구가 요구된다. Purpose: The purpose of this study was to investigate how the social and physical environment variables affect the exercise self-schema from the social ecological perspective and to provide basic data for establishing the intervention strategy of physical activity promotion. Methods: A total of 238 of 50s male participated in the Sports Event in Gyeonggi-do were used in the final analysis. Exercise self-schema, social environment, physical environment, exercise intention questionnaires were used. Confirmatory factor analysis, reliability analysis, correlation analysis and structural equation model analysis were conducted to derive the study results. Results: First, both the social environment and the physical environment have a positive effect on the exercise self-schema. Second, exercise self-schema and physical environment have a positive effect on exercise intention. However, the social environment did not directly affect the intention to exercise. Conclusion: Based on the results that social and physical environment have a positive effect on the exercise self-schema, environmental factors were found to be helpful for the exercise behavior. In addition, many further studies on the development of the physical activity promotion program are needed.
