The occupational injury and illness(OII) was influenced by the various factors. This study was planned to investigate the pathway of the activities of OSHM on the rate of OII via worker's participation. The survey on the trend of the activities of OSHM was used. The sample size of manufacturing industry was 3,000 enterprises and that of construction was 1,000 enterprises. The survey was done by interview method with structure questionnaire. Questions about the activities of OHSM were integrated into one category using factor analysis. The enterprises with OII has more activities of OSHM than that without OII. Among enterprises with OII, the level of the activities of OSHM was positively correlated with the rate of OII. The activities of OSHM has influenced on the rate of OII directly and indirectly via worker's participation and the activities of prevention of accident. Worker's participation also has the direct effect and indirect effect on the rate of OII. Worker's participation in construction sector has more effect on OII than that in manufacturing sector.

Although hazard identification is one of the most important steps of safety management process, numerous hazards remain unidentified in the construction workplace due to the dynamic environment of the construction site and the lack of available resource for visual inspection. To this end, our previous study proposed the collective sensing approach for safety hazard identification and showed the feasibility of identifying hazards by capturing collective abnormalities in workers' walking patterns. However, workers generally performed different activities during the construction task in the workplace. Thereby, an additional process that can identify the worker's walking activity is necessary to utilize the proposed hazard identification approach in real world settings. In this context, this study investigated the feasibility of identifying walking activities during construction task using Wearable Inertial Measurement Units (WIMU) attached to the worker's ankle. This study simulated the indoor masonry work for data collection and investigated the classification performance with three different machine learning algorithms (i.e., Decision Tree, Neural Network, and Support Vector Machine). The analysis results showed the feasibility of identifying worker's activities including walking activity using an ankle-attached WIMU. Moreover, the finding of this study will help to enhance the performance of activity recognition and hazard identification in construction.

The change in labor consciousness began to draw social attention to work-life balance (WLB). The WLB is one of the major factors affecting the health and safety problems of workers. Although shiftwork adversely affects WLB, safety, and health problems of workers, WLB of shift workers has received little empirical attention. The purpose of this study was to examine whether WLB mediates the relationship between shiftwork and shift worker's safety and health problems, participation in leisure activities moderates WLB, and finally, whether WLB moderated by participation in leisure activities mediates the relationship between shift work and shift worker's safety and health problems. For the study, the data of the 5^th wave of Korean Working Condition Survey(KWCS) conducted by Korea Occupational Safety and Health Agency(KOSHA) of South Korea was used. Conditional process analysis revealed that the relationship between shift work and worker's safety and health problems is mediated by WLB; however, participation in leisure activity showed no moderation effect on WLB. Therefore, the moderated mediation effect has failed to achieve statistical significance. The results indicate that working environment improvement in consideration of the WLB is needed to gain shift worker's long-term safety and health. The implications of this study and suggestions for future research were discussed.

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 designed to analyse the performance and the mechanisms of workers' participation and communications in industrial accident prevention activities leading to the reduction of industrial accidents. This study also aimed to find out the causal relationship influencing the promotion of prevention activities of industrial accidents. Of the manufacturing businesses with more than 5 workers as the population of the survey, a questionnaire was conducted with 2,500 workspaces chosen by stratified sampling. Out of 2500 workspaces, 971 workspaces equipped with industrial safety and health committee were analysed in this study. According to the results of this study, the primary influential factors on safety activities were the management of industrial accidents and the cooperations between supervisors and workers on site. The secondary influential factor was the establishment of industrial safety and health committee. Regarding the effectiveness of industrial accident reduction, -0.01 was shown by workplace safety activities by themselves and -0.09 was shown by participation and communications through indirect safety activities. This indicated workers' participation and communications play an important role in the reduction of industrial accidents. By discovering the clue to the mechanism of the workers' participation and communications, this study is expected to stimulate the reduction of industrial accidents by emphasizing the importance of workers' participation and communications in resolving the safety and health problem in the workplaces.

Objectives: The major objective of this study was to develop and validate a tier 1 exposure model utilizing worker exposure monitoring data and characteristics of worker activities routinely performed at construction sites, in order to estimate worker exposures without sampling. Methods: The Registration, Evaluation, Authorization and Restriction of Chemicals(REACH) system of the European Union(EU) allows the usage of exposure models for anticipating chemical exposure of manufacturing workers and consumers. Several exposure models have been developed such as Advanced REACH Tools(ART). The ART model is based on structured subjective assessment model. Using the same framework, a tier 1 exposure model has been developed. Worker activities at construction sites have been analyzed and modifying factors have been assigned for each activity. Korean Occupational Safety and Health Agency(KOSHA) accrued work exposure monitoring data for the last 10 years, which were retrieved and converted into exposure scores. A separate set of sampling data were collected to validate the developed exposure model. These algorithm have been realized on Excel spreadsheet for convenience and easy access. Results: The correlation coefficient of the developed model between exposure scores and monitoring data was 0.36, which is smaller than those of EU models(0.6~0.7). One of the main reasons explaining the discrepancy is poor description on worker activities in KOSHA database. Conclusions: The developed tier 1 exposure model can help industrial hygienists judge whether or not air sampling is required or not.

Pilots' fatigue is one of the most serious threat to flying safety. Fatigue is influenced by many factors like sleep deprivation, daily activities, aging, stress, etc. This study was designed to investigate military pilots' daily activities. 20 pilots' daily activity was monitored by activity monitor, Fitbit(R), and the survey about sleep time and flight time was conducted. They placed Fitbit(R) on their waist for 5 days. During flight, they removed Fitbit(R) that had been used for checking their steps and walking distances. It was found that the average sleep time is 6.7 hours for fighter pilots. It was a little shorter than average sleep time for adults, 8 hours. Average steps per day was 6,838 which is more than sedentary worker's but less than active worker's. Their daily activities were not as high as we had expected. But their sleep time was very short. Flight surgeons should recommend them to take a rest and get sleep during rest period.

This paper provided a brief summary of the current strategic goals, activities, and impacts of the NIOSH (National Institute for Occupational Safety and Health) occupational injury research program. Three primary drivers (injury database, stakeholder input, and staff capacity) were used to define NIOSH research focuses to maximize relevance and impact of the NIOSH injury-prevention-research program. Injury data, strategic goals, program activities, and research impacts were presented with a focus on prevention of four leading causes of workplace injury and death in the US: motor vehicle incidents, falls, workplace violence, and machine and industrial vehicle incidents. This paper showcased selected priority goals, activities, and impacts of the NIOSH injury prevention program. The NIOSH contribution to the overall decrease in fatalities and injuries is reinforced by decreases in specific goal areas. There were also many intermediate outcomes that are on a direct path to preventing injuries, such as new safety regulations and standards, safer technology and products, and improved worker safety training. The outcomes serve as an excellent foundation to stimulate further research and worldwide partnership to address global workplace injury problems.
