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.

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%.

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.

This paper first introduces the U. S. pension system and its current trends. Then the following two sections discuss the research on worker behavior of defined contribution plans, a popular pension plan available for American workers in recent years, and the adequacy of retirement income among American people. The last section is a summary. This paper reviews the trend of the U. S. pension system, research on worker's behavior of defined contribution retirement plans, and studies on retirement income adequacy. These themes may have common or different features in other countries, such as Korea. This paper provides helpful information for private and public policy makers and researchers of these topics in Korea to advance their understanding of pension and retirement behavior and facilitate effective policy making of pensions and retirement.

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.
