Purpose: This study was conducted to understand the situation of general hospital worker's health management and health promotion. Methods: To investigate the current situation of health management in the hospital, structured questionnaires were sent to 122 occupational health providers by post. About 79% hospitals returned questionnaires. The data were analyzed using descriptive analysis, ${\chi}^2$-test by SPSS 12.0 program. Results: A quarter hospitals responded set up separated health care office for workers, 87.5% provided health educations, and 56.5% operated health promotion projects. In the contents of health promotion program embraced both health behavior practice and disease prevention, musculoskeletal disease control, infection control, smoking cessation, and exercise program were most commonly provided to the workers in order. Occupational health care provider chose the item such as budget limitation, manager's apathy, lack of employee's participation, cooperation provider, and so on as the reason of difficulty to run health promotion program in the hospital setting. Conclusion: Hospital managers need to construct infra to manage and promote worker's health. For example, establishing Industrial safety and health committee in hospital and arranging nurses who being fully responsible to worker's health.

With the aim of preventing safety accidents at construction sites, the company aims to create safe behaviors intended through variables called smart safety and health activities to help reduce industrial accidents. Purpose: It analyzes how smart safety and health activities affect accidents caused by unsafe behavior and changes in worker behavior, which is the root cause, and verifies the hypothesis that it helps prevent safety accidents and protect workers' lives. Method: Smart safety and health activities were selected as independent variables (X), and intended safety and anxiety, which are workers' behavioral intentions, were set as dependent variables (Y), attitude and subjective norms, and planned behavioral control as parameters (M). Exploratory factor analysis, discriminant validity analysis, and intensive validity analysis of safety and health activities were used to analyze the scale's reliability and validity. To verify the hypothesis of behavior change, the study was verified through Bayesian model analysis and MC simulation's probability density distribution. Result: It was found that workers who experienced smart safety and health activities at construction sites had the highest analysis of reducing unstable behavior and performing intended safety behavior. The research hypothesis that this will affect changes in worker behavior has been proven, the correlation between variables has been verified in the structural equation and path analysis of the research analysis, and it has been confirmed that smart safety and health activities can control and reduce worker instability. Conclusion: Smart safety and health activities are a very important item to prevent accidents and change workers' behavior at construction sites.

This study was a quasi-experimental research of a non-equivalent control group and non-synchronized design for analyzing the effects of fire safety education on care worker trainees. The subjects of the study were care worker trainees of the S Care Worker Institution: 57 trainees with 28 in the experimental group, and 29 in the control group. The research period was from May 21 to June 14, 2018 and the experiments focusing on fire safety education were performed once per week for a total of four times over the research period. The data were then analyzed using a ${\chi}^2-test$ and t-test. The results showed that fire safety education is an effective source of education for increasing the knowledge on fire safety, attitudes towards fire safety, perceived behavioral control on fire safety, behavioral intention on fire safety, and fire safety behavior in addition to being incredibly useful in practicing fire safety behaviors throughout their daily lives. On the other hand, the subjective norms on fire safety did not show any significant differences. Therefore, this paper suggests a follow-up study that should focus on analyzing the effects of the subjective norms on fire safety.

Purpose: The purpose of this study was to identify factors influencing exercise behaviors of the male manual workers and office workers based on health promotion model by examining the relationships among them, and then to provide basic information for developing exercise program. Methods: The 97 laborers and 99 officiers were collected from two worksites. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression. Results: Male laborers' exercise behavior was significantly influenced by exercise self-efficacy, exercise social support and exercise experience over 3 months, and these factors explained 50.2% of the total variance. Male officiers' exercise behavior was significantly influenced by exercise self-efficacy, subjective health status, perceived exercise barriers and exercise social support, and they explained 47.3% of the total variance. Conclusions: Based on the findings that exercise self-efficacy and exercise social support commonly influence exercise behavior of male laborers and officiers, there is a need to develop an exercise program to improve exercise self-efficacy and exercise social support.

This study attempts to explain how the social-worker empowerment in the field of social work relates to social-work self-efficacy and whether or not the transactional leadership of the leader moderates the relationship between these two variables. Data from 390 social workers working with public and private sector agencies in Seoul were collected. For the questionnaire and analysis, this research uses the Social Worker Empowerment, Social Work Self-Efficacy, and Transactional Leadership scales. This research utilizes a wide range of statistical analyses, such as descriptive analysis, Pearson's correlation, reliability analysis, factor analysis, multiple regression, and general linear modeling. The calculations employed the use of SPSS/PC+ 12.0. This research indicates, among other things, that social workers with a high level of social worker empowerment and transactional leadership of the leader show a tendency toward higher social work self-efficacy and that the leader's transactional leadership level plays a moderating function in the relationship between social-worker empowerment and transactional leadership of the leader. In conclusion, a social worker with a low level of leader's transactional leadership shows a relatively greater tendency toward social work self-efficacy when compared to a social worker having a high level of leader's transactional leadership. Social workers and social-work organizations seeking professional practice can benefit from these findings on the relationship between professional behavior and social work self-efficacy with perceived transactional leadership about a team leader as a moderator.
