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.

Background: To investigate the relationship between musculoskeletal disorders and comorbid health problems, including depression/anxiety disorder, insomnia/sleep disorder, fatigue, and injury by accident, and to determine whether certain physical and psychological factors reduce comorbid health problems. Methods: In total, 29,711 employees were selected from respondents of the Third Korean Working Conditions Survey and categorized into two groups: Musculoskeletal Complaints or Musculoskeletal Sickness Absence. Four self-reported health indicators (overall fatigue, depression/anxiety, insomnia/sleep disorder, and injury by accident) were selected as outcomes, based on their high prevalence in Korea. We used multiple logistic regression analysis to determine the relationship between comorbid health problems, musculoskeletal complaints, and sickness absence. Results: The prevalence of musculoskeletal complaints and musculoskeletal sickness absence due to muscular pain was 32.26% and 0.59%, respectively. Compared to the reference group, depression/anxiety disorder and overall fatigue were 5.2-6.1 times more prevalent in the Musculoskeletal Complaints Group and insomnia/sleep disorder and injury by accident were 7.6-11.0 times more prevalent in the Sickness Absence Group. When adjusted for individual and work-related physical factors, prevalence of all four comorbid health problems were slightly decreased in both groups. Conclusion: Increases in overall fatigue and depression/anxiety disorder were observed in the Musculoskeletal Complaints Group, while increases in insomnia/sleep disorder and injury by accident were observed in the Sickness Absence Group. For management of musculoskeletal complaints and sickness absence in the workplace, differences in health problems between employees with musculoskeletal complaints and those with sickness absence as well as the physical and psychological risk factors should be considered.

This study investigated health problems and work-relatedness for fishermen. In total, 121 fishermen (103 males and 18 females) were extracted from the data of the 6th Korean Working Conditions Survey. Two groups (Symptomatic and Asymptomatic) were statistically compared in terms of health problems and exposure to hazards. The most common health problems identified for fishermen were muscular pain in the shoulder, neck, and upper limbs (73.6%), backache (71.1%), muscular pain in the lower limbs (58.7%), overall fatigue (33.9%), headaches or eyestrain (22.3%), and anxiety (8.3%). These health problems were found to be related to the working conditions of the fishermen (low temperatures, tiring or painful postures, stance, sitting position, repetitive hand or arm placement, and the experience of stress). This study's findings may help us better understand the characteristics of the health problems and work-relatedness of fishermen and could be helpful for improving fishermen's overall health and safety.

Though safety signs are important since they transmit hazard information even after diverse accident prevention treatments, their functional effectiveness were never tested in Korea so that even those provided by Occupational Safety & Health Act(OSHAct) could not accomplish their objectives, "effective accident prevention", This research was carried out to understand confronted problems and improvement direction for safety signs provided by OSHAct. For them, current safety signs were analyzed with a semiotic view on one hand, and a questionnaire survey was conducted with safety-related people in industrial fields on the other hand. To summarize problems in semiotic aspects, geometric simplicity of pictograms in safety signs seemed to be so emphasized that they might fail to induce realistic action, and their esthetic sensation seemed to be lower than those of developed countries. And according to present questionnaire survey, it was pointed out that; 1) legal systems related with safety signs were not classified appropriately, 2) safety signs were recognized as difficult to understand and inapplicable to industrial fields, and eventually 3) safety signs were not effectively utilized for industrial accident prevention. Therefore, discussions for improving confronted problems and relation to international standards were added at the end.

This study was intended to develop a multi-purpose, multi-functional design for safety vest to enhance the safety and user's availability. With a limited scope to LED-applied safety vest, this study contemplates on the problems of safety vest on the market and directions for design development with a view to develop its prototype. This is a significant study because it has been conducted concerning a prototype, a cut above the study method of constructing a basic theory. For study method, theoretic considerations on LED and safety vest are followed by case study for LED-applied safety vest currently on the market to draw out problems. Then, solutions for problems with LED safety vest will be found, while planning for a design direction in consideration of safety, functionality and beauty. Scope of study was limited to cases of LED safety vests currently on sale online and offline, excluding cases of common-form luminosity such as HB luminous vest without LED. Accordingly, results of study will help develop the prototype for LED safety vest with an increase of the wearer's safety, and be used as a basic data for developing high-value-added fashion prodcts to meet his aesthetic sense and functionality. This study has limitations. Restricted scope for LED-applied safety vest should be extended to an outdoor wear in follow-up research for the foundation of higher value added.

Inspection of RCS flow measurements for the domestic pressurized water reactors has been performed by the Korea Institute of Nuclear Safety (KINS) as one of the authorized periodical inspection activities. The inspection results for the Westinghouse-type plants reveal that 1) the RCS flow instrumentation has been calibrated by using the initial design and commissioning test result, without reflecting the cycle specific reference flow measurements, 2) the loop-to-loop now variation in the actual flow measurement which has not been considered in the safety analysis affects the asymmetric How transient results, and 3) the measured RCS flows in Kori 3 and 4, Yonggwang 1 and 2 do not support the definition of the best estimate RCS flow, approaching the RCS flow limit. In this study, the revealed problems were discussed with review of the design and the RCS flow measurement uncertainty evaluation, and the technical approaches and recommendations for resolving these problems were proposed.

Korean industries have been tend to depending upon historical information to control risk. The other hand, foreign industries have been identify risk factors using system safety techniques to predict future risk. One agency or person could not solve the problems of total safety system for improving productivity. In order to solve those problems, the production-safety group is necessary, and safety control system must be adapted by fitting to the production flow. This paper is present the methodology of driving occupational safety programs to increase productivity.

Elderly welfare facilities are extremely susceptible to mass casualties in disastrous situations, such as fire, due to the limited physical and mental abilities of their residents. This study examined the status of fire safety management, including the structural problems of elderly welfare facilities, problems of the installation and management of firefighting systems, and problems regarding of fire safety managers. After the Sejong Medical Welfare Facility fire, these problems have been complemented by retrofitting firefighting systems in accordance with the revision of the relevant laws and regulations. On the other hand, the overall status of fire safety management is still insufficient. Therefore, it is important to improve the stability of buildings and firefighting systems as well as fire safety management through additional revision of the relevant laws and regulations.
