Safety management agent manages the risk behavior of the worker with the naked eye, but there is a real difficulty for one the agent to manage all the workers. In this paper, IoT device is attached to a harness safety belt that a worker wears to solve this problem, and behavior data is upload to the cloud in real time. We analyze the upload data through the deep learning and analyze the risk behavior of the worker. When the analysis result is judged to be dangerous behavior, we designed and implemented a system that informs the manager through monitoring application. In order to confirm that the risk behavior analysis through the deep learning is normally performed, the data values of 4 behaviors (walking, running, standing and sitting) were collected from IMU sensor for 60 minutes and learned through Tensorflow, Inception model. In order to verify the accuracy of the proposed system, we conducted inference experiments five times for each of the four behaviors, and confirmed the accuracy of the inference result to be 96.0%.

The objectives of this study are examine the variables effecting management behavior of home-band worker through empirical study. The data used for statistical analysis is 285 home-based worker. The statistical methods used for data analysis were frequencies, mean, t-test, multiple regression, factor analysis and path analysis. The major findings can be summarized as fellows. Home-based workers' various characteristics were statistically significant variable to management behavior. Home-based work income were higher for older women, no employ experience in out of home, lower age of children, business owner, lower time flexibility. In cause-effect model analysis that affects life satisfaction was related to work management, home management behavior and income. Based on the finds of the study, it was found that home-based work can be good alternative to induce married women to labour market if some problems are covered.

In recent years, the most safety studies have been focused on identifying the relationship between safety climate and safe work behavior in accordance with the awareness that prime causes of accidents are organizational, managerial, and human factors rather than pure technical failures across the world. This study focused empirical research aimed at finding out the safety climate factors and examining the relationships of the safety climate and safe work behavior in construction site in Korea, too. A 10 numbers of safety climate factors were adapted from the Mohamed's study(2002) and tested using PLS-GRAPH 3.0 expecting same results as Mohamed' study. And then the relationship between safety climate and safe work behavior was examined. Only two safety climate factors-personal risk appreciation and worker's safety competence-were found and a strong positive relationship between safety climate and safe work behavior was identified in this study. Discussed in details about the results and implications and suggested further studies.

Purpose - This purpose of this research is to verify the influence of the care workers' environment on their job satisfaction and on their voluntary behavior. Research design, data, and methodology - Data were collected from care workers at elderly medical and home care facilities in Korea in Seoul and Kyung-ki. Of 367 total respondents, 285 responses were used. This study performed exploratory factor analysis in order to verify the validity and credibility of the data. Regression analysis was conducted to verify the influence of the working environment, which encompasses the worker's relationship with the agency and with the elderly, on job satisfaction. Results - The hypothesis results were: First, from analyzing the influence of the working environment on the worker's job satisfaction, both relationship with the agency (p<.001) and relationship with the elderly (p<.05) positively affect job satisfaction; second, the exploratory analysis verifies the influence or the working environment on job satisfaction. Conclusions - The results indicate that the relationship with the agency (p<.001) and relationship with the elderly (p<.001) both positively affect the voluntary behavior of the workers.

The purpose of this study is to investigate the influence of social workers' emotional labor on non-task behaviors. This study characterizes emotional labor as deep acting and surface acting, non-task behavior as organizational citizenship behavior(OCB) and counterproductive work behavior(CWB). And this study also examines the mediating effect of social workers' emotional dissonance in the relationship between surface acting and non-task behavior, and the moderating effect of senior worker's emotional leadership in the relationship between emotional dissonance and non-task behaviors. The results from this study are as follows. Firstly, social workers' deep acting improves their OCB. Secondly, social workers' surface acting has strong effects on their emotional dissonance, and this emotional dissonance hinders their OCB. In addition, the mediating effect of emotional dissonance is also recognized at this point. Thirdly, senior worker's emotional leadership moderates the relationship between social worker's emotional dissonance and OCB in the sense that emotional leadership is expected to reduce the negative effects of emotional dissonance on OCB. However, the influence of emotional labor on CWB has no statistical significance in this study. Based on these results, detailed theoretical and practical implications are discussed.

Most industrial accidents occur when the workers' unsafe behavior and the unsafe situation of workplace take place at the same time. Although human's unsafe behavior is indispensable to work field, the evaluation scheme to detect the causes for the accident resulted from human's unsafe behavior and counterplan should be prepared to prevent and reduce accident. To do this, we first classify the specific background factors in terms of human inner factor and environment factor and then develop the AHP (Analytic Hierarchy Process) model to analyze the background factors that affect the worker's unsafe behavior. We also develop a checklist to be able to evaluate the occurrence possibility of individual worker's unsafe behavior.

Burnout is a severe psychological and physical syndrome that occurs in response to prolonged stress at work. It brings enormous costs to both organizations and individuals because it negatively impacts employees' job attitudes and leads to undesirable behaviors. The purpose of this study was to examine the negative effects of job burnout on the organizational commitment and organizational citizenship behavior of social worker. Organizational citizenship behaviors are efforts by employees above and beyond what is expected. For the research, burnout was consisted of emotional exhaustion(EE), depersonalization(PA) and diminished personal accomplishment(DP) by Maslach and Jackson's MBI. This study analyzed 342 social workers in private social welfare organizations by survey. The results of this study were summarized as follows: Social Workers had negative correlation to burnout on the organizational commitment and organizational citizenship behavior. Especially, EE, PA and DP had a negative effect on the organizational commitment; PA and DP had a negative effect on the organizational citizenship behavior. This study finally discussed theoretical implications for future study and practical implications for burnout strategies on the results.
