Objectives: The question of whether the level of fees paid to working environment measurement agencies is appropriate has long been a matter of concern to the government. In addition, measurement institutions express dissatisfaction with their level of compensation, which has a great influence on the evaluation of a subject's policy. This study is intended to find a way to appropriately calculate working environment measurement fees. Methods: We looked at the principle of fee determination as a basic theory of fee calculation used in fee calculation, the legal and academic aspects of the general method of fee calculation, and government cost calculation standards. Furthermore, we reviewed the research methods applied so far to derive a method of calculating fees appropriate for this environment. Results: The working environment measurement environment is different from other commission calculation environments. The other environment is to appropriately calculate the service price provided by a monopoly public enterprise, while the situation is to appropriately calculate the fees provided by competitive private enterprises. Therefore, the service delivery environment and the delivery entity are different. In this case, the appropriate method of calculating service fees would be competitive pricing. There have also been many problems under the method of calculation by service cost. Conclusions: First, the working environment measurement fee requires an accounting correction of endogenous variables. Second, the theory of calculating fees appropriate for this situation is appropriate for competitive pricing that applies to private competitors. Third, the government should make efforts to make the service supply market a fully competitive market while ensuring that the service fee level is determined at the marginal cost level. Fourth, economically, research on marginal cost levels is needed.

The purpose of this study is to investigate effects of management support for health and safety on workers' safety perception. Since the 1990s, Korea's national competitiveness has been rising rapidly, but efforts to prevent and cope with industrial accidents are still insufficient. Particularly there is a big movement to strengthen corporate responsibility for serious accidents in the 2020s. In this study structural equation model(SEM) was constructed and quantitatively analyzed in order to know how management's support affects the organization, system, and communication related to safety and health in the company, and ultimately how it has an effect on workers' safety perception. 4,169 questionnaires conducted by the Institute for Occupational Safety and Health were used as observation variables, and 5 hypotheses were established and were verified in SEM. As management support increases, organization & institution for a safe workplace, communication related with safety and health within the company become more active. Finally management support has a positive effect on workers' safety perception. The results of this study imply that management needs to increase awareness of the importance of safety and health before all measures such as organizations, institutions, and communication related to safety and health.

The study was conducted with 11,211 adults, and the health-related quality of life was defined using the EuroQol group's EQ-5D and physical activity using GPAQ. Data analysis was performed using the SAS 9.4 program, the general characteristics and degree of physical activity of the subject, Chi-square for KEQ-5D index, and Logistic Regression Analysis for the relationship between physical activity and quality of life. As a result of the study, the general characteristics of the subjects were marital status, educational status, occupation, smoking, alcohol consumption, economic status, stress, chronic disease, chronic disease treatment, physical activity due to leisure and physical activity due to occupation, depending on gender. There was a difference (p<0.05). As for the quality of life related to physical activity and health, the quality of life was significantly lower by 37% in the 'minimum physical activity group' of occupational physical activity (p<0.05). The results of this study are expected to be provided as basic data for physical activity-related health policy establishment and physical activity programs.

The aim of this study was to investigate the effects of virtual reality training on upper extremity function and activities of daily living in patients with sub-acute stroke. The present study enrolled 18 patients with sub-acute stroke. All subjects were assigned into either the experimental group (n=9) or control group (n=9). Both groups received conventional occupational therapy for 30 minutes/day, 5 times a week, for 4 weeks. Additionally, the experimental group performed virtual reality training in each session for 30 minutes/day, and the control group conducted conventional occupational therapy in each session for 30 minutes/day. The outcome measures were performed through the Fugl-Meyer Assessment (FMA) and the Korean-modified Barthel Index (K-MBI) before and after intervention. In results, the experimental group showed significant improvements in the scores of FMA and K-MBI after intervention (p<.05). The control group showed significant improvements in the shoulder/elbow/forearm, wrist, and hand sub-domains of the FMA and K-MBI (p<.05). After intervention, the experimental group showed significantly greater improvements in the total score and in the wrist and hand sub-domains of the FMA than control group (p<.05). These findings suggest that virtual reality training may have positive effects on the improvements of upper extremity function in patients with sub-acute stroke.

Appropriate air quality in the pig building is essential to prevent farmers' health as well as to increase pig performance. This on-site experiment was conducted to assess dust reduction efficiencies of several liquid additives with spaying method in the enclosed pig building. The mean reduction rate of total dust only after spray was approximately 30% for all the treatments compared to initial level before spraying additives, which was found to reduce the initial level of total dust significantly (p<0.05). The mean reduction rate of all the treatments at 1hr after spray was about 24% which was 6% lower than only after spray. Since 3hr after spray, however, total dust level were fluctuated variably for all the treatments besides application of the soybean oil. Based on this result, effect of soybean oil on dust reduction in the enclosed pig building was most prominent among liquid additives evaluated in terms of efficiency and duration.
