The purpose of this study was to verify whether there are any differences in the level of physical self-efficacy, depression and stress of meddle-aged men according to the stage of exercise change. As for the study objects, men at the ages between 40 and 50, residing in Seoul and mostly having temporary jobs, office jobs and professional jobs, were surveyed with the questionnaire prepared, and 299 copies of the questionnaire in total were collected and used for the final analysis. SPSS 12.0 was used for the processing of the data, while the results were deduced by using exploratory analysis, reliability analysis, 1-way ANOVA and correlation analysis. The study results were as follows: Firstly, their Physical self-efficacy showed significant differences according to the stage of exercise change of the study objects, and as a result of the post-hoc analysis, it was found that as the stage became higher, their physical self-efficacy became higher as well. Secondly, the level of depression showed significant differences according to the stage of exercise change of the study objects, and as a result of the post-hoc analysis, it was found that as the stage generally became higher, their depression showed lower levels. Thirdly, their stress showed significant differences according to the stage of exercise change of the study objects, and as a result of the post-hoc analysis, it was found that the preparation stage had a lower level of stress than the maintenance stage while the before-plan stage had a lower level of stress than the before-plan stage and the maintenance stage. Fourthly, it was found that as the stage of exercise change became higher, their stress tended to decrease while their self-efficacy tended to increase.

This study was designed to investigate the relationship between the stages of exercise behavior change and physical self-concept and self-efficacy of security employees in hotel casinos. The sampling was drawn from employees at 8 casinos which had more than 30 employees. Participants were selected by convenience sampling method and they completed questionnaires about Physical Self-Concept and Self- Efficacy by self-administration method under supervision of trained researchers SPSS 16.0 (Statistical Package for the Social Science) was used for data analysis in the present study. Reliability and validity were examined for the present study. The principle component factor analysis and varimax rotation were used for the present study. Eigen value 1.0 was the criterion for selecting factors. Chi-square (X) 2 test was utilized for measuring the difference in gender and types of job duties at the stages of exercise behavior change. One-way ANOVA was employed to examine the relationship between the stages of exercise behavior change as an independent variable and physical self-concept and self-efficacy as dependent variables. The Scheffe method was used to determine mean differences of groups as a follow-up test. Multiple regression analysis was utilized to test the difference of physical self-concept as dependent variable and self-efficacy as independent variable. To verify hypothesis for the study, a statistical significance level of $\alpha$=.05 was used. The results were as follow: first, there were differences found for gender and types of job responsibilities in the stages of exercise behavior change. Secondly, as security employees progressed through the stages of exercise behavior change, their physical self-concept and self-efficacy improved. Finally, physical activity and body fat had significant main effects on self-efficacy.
