  • To elucidate the composition of bumblebee (Bomb us terrestris) venom (BBV) and the anti-inflammatory effect of BBV. The major components of BBV by LC chromatography and SDS-PAGE were identified. The production of nitric oxide (NO) and proinflammatory cytokines was examined by lipopolysaccharide (LPS) in a macrophage cell line, RAW 264.7 cells, with BBV. BBV inhibits LPS-induced NO in a dose dependent manner. We also found that BBV inhibits proinflammatory cytokine, tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-6 production. These findings mean that BBV can be used in controlling macrophages mediated inflammation related disease. Additional studies on the pharmacological aspects of the individual components of BBV are recommended for future trials.

  • Purpose: This study explores how demographic transitions with workforce implications taking place in South Korea are affecting the job market, and proposes a novel conceptual model to analyze the increased role that migrant workers will play as the changes progress in the medium term. Research design, data and methodology: A qualitative approach based on the available published data is used in order to create a conceptual model that could be used to determine the order in which job sector strata will be gradually taken over by migrant workers, as the demographic transitions will create an increasing need for workforce reforms. Results: The study determines that migrant workers will replace domestic Korean workers in a stratified manner, initially in rural areas, followed by regional cities and then in the industrial areas on the edges of big cities, and the strata can be analyzed based on a proposed four-category model to determine where the opportunities will open. Conclusion: It is possible to use a conceptual model for this phenomenon. Extensive Government planning is needed to avoid possible social exclusion problems and to determine how to keep the economies of rural and regional Korean cities economically viable while they are becoming increasingly depopulated.

  • Purpose: This study examined the effects of the forward head posture and tension type headache on neck movement among office workers. Methods: The subjects were 6 male and 21 female patients composed of a forward head posture group, forward head posture group with a tension type headache and a normal group. Each group consisted of 2 males and 7 females. The cranio-vertebral angle of the head and the angle of motion of the neck were measured. SPSS 23.0 was used for data analysis and one-way ANOVA was performed for the mean comparison of the neck movements in the three groups. Results: The participants had a limitation in the movement of all necks between the forward head posture group and forward head posture with tension type headache group compared to the normal subjects. The forward head posture with tension headache group had limited neck extension and lateral bending compared to the forward head posture group. Conclusion: Office workers have limitations in the movement of the neck when they are accompanied by forward head posture and tension headache. In particular, when accompanied with a tension headache, there is a restriction on the neck extension and side bending. This study is expected to provide basic data for the relief of tension headache and the treatment of forward head posture in office workers.

  • The entire construction safety is significantly influenced by proper uses of temporary structures. However, in current practices, temporary structures are used without sufficient planning and analysis on their impact on safety. Consequently, problems in worker safety and loss of productivity are frequently caused related to temporary structures. This paper introduces an approach that uses Building Information Modeling (BIM) to automatically create temporary structures as part of construction plans and identifies potential safety hazards related to the temporary structures. In this study, the type of temporary structure is limited to scaffolding. Automation algorithms were developed and applied to (1) analyze daily construction site conditions (2) create required scaffolding objects, and (3) identify potential safety hazards related to scaffolding. A case study using a real-world construction project demonstrated that scaffolding objects were properly created based on user-input and potential safety hazards were successfully identified without human intervention.

  • Purpose: This study was conducted to investigate the prevalence and risk of gout in healthy workers. Methods: This cross-sectional analysis was conducted in 1,876 subjects (1,515 men and 361 women) enrolled in the Healthy Worker Cohort Study at Daegu, South Korea. Relationships between serum uric acid levels and independent risk factors were evaluated using multiple linear regression analysis after adjustment for covariates. Results: Among study participants, the prevalence of gout was 22.9% in men and 2.5% in women (based on a serum uric acid level >7.0 mg/dL for men and >6.0 mg/dL for women). Among men, increased ALT, GGT, total cholesterol, and triglycerides were associated with increased risk of gout (p<0.05) by multiple linear regression analysis; however, increased age and HDL-cholesterol/triglyceride ratio were associated with decreased risk of gout (p<0.05). In women, increased triglycerides were associated with increased risk of gout (p<0.05). Conclusion: Our findings suggest that increased triglycerides were significantly associated with the risk of gout in men and women. Moreover, a high HDL-cholesterol/triglyceride ratio in men may reduce the risk of gout.

  • The purposes of this study were to identify patterns and trends of nursing studies of workers' stress conducted in Korea over the last two decades, and to suggest the direction of future research activities. Research studies of workers' stress were collected from the abstract and the title lists of studies using internet search. The total number of studies used for this study was 118. The analysis of these studies showed that the studies of workers' stress have increased rapidly since 1995, but most of them were non-experimental design studies. They tended to be conducted more on nurses, and used confusedly in stress terms. Instruments developed by the authors were the most popular. Moreover, the organizational variables of the stress-related concept were barely used except nurses' stress. Therefore, it was needed to identify and clarify the terms of stress among the authors, and to develop the workers' stress management programs and examine their effects. Especially studies that include the organizational variables of workers' stress need to be done in the future.
