Purpose: This study was conducted to identify factors affecting mental health and behavioral problems among high school students through the lens of a Social Cognitive Career Theory. Methods: A descriptive study was carried out with 384 high school students in Seoul, Korea. A self-administrative questionnaire was used. It consisted of items on person background variables, career-related variables including career barriers, learning experiences, self-efficacy, outcome expectations, and career indecision, and mental health and behavioral problems. Descriptive statistics, correlation analysis and multiple regression analysis were performed using the SPSS 21.0 program. Results: The results showed that perceived stress (t=5.12, p<.001), perceived health status (t=-4.08, p=.002), and school record (t=5.46, p<.001) were statistically significant variables. Also, career barriers (t=10.57, p<.001) was a significant factor influencing mental health and behavioral problems. Conclusion: These findings indicate that among career-related variables, career barrier needs to be considered for preventive and therapeutic approach to mental health and behavioral problems in adolescents. Furthermore, the results suggest that career-related stress level should be assessed in high school students on a regular basis.

Purpose: The purpose of this study is to examine the mediating effect of acculturative stress on the impact of satisfaction with life and career identity on depression among the Vietnamese students enrolled in a language course in Korea. Methods: A questionnaire survey was conducted to get answers of 225 Vietnamese students enrolled in the language course in a college in Busan. Data were collected from November to December 2018. The Data were analyzed with descriptive statistics, Pearson's correlation coefficients and path analysis using SPSS/WIN 20.0 and Amos 18.0 program. Results: Acculturative stress was affected by satisfaction with life (β=-.43, p<.001) and career identity (β=-.45, p<.001). Furthermore, depression was affected by acculturative stress (β=.49, p<.001) and career identity (β=-.25, p<.001), but depression was not affected by the satisfaction with life (β=-.15, p=.029). The mediating effect of acculturative stress between two exogenous variables(satisfaction with life and career identity) and depression was proved. Conclusion: The result of this study suggests that it is necessary to develop an intervention program to reduce the acculturative stress and depression of Vietnamese students enrolled in the language course.

Reactive oxygen species (ROS) are produced by oxidative stresses which cause various chronic diseases such as diabetes and obesity. Ginseng (Panax ginseng C.A. Mayer) has been reported to contain various biological activities such as anti-cancer, anti-diabetic, neuroprotective, radioprotective, anti-amnestic and anti-aging effects. In this study, we investigated the effects of Panax ginseng, treated with high temperatures and high pressures, on oxidative stress in C2C12 myoblasts and 3T3-L1 adipocytes. Oxidative stress was induced in the C2C12 cells through the introduction of $H_2O_2$ (1 mM), and cells were then treated with various ginseng preparations: dried white ginseng (DG), steamed ginseng (SG) and high temperature and high pressure treated ginseng (HG). In addition, 3T3-L1 preadipocytes were treated with various ginsengs for up to 8 days following standard induction of differentiation. Our results show that HG treatment significantly protected oxidative stress in both cell lines and enhanced gene expression of antioxidant enzymes. Therefore, in this study, we investigated the protective effects of ginseng on the oxidative stress of adipocytes and muscle cells.

The study aims to evaluate job stress, self-efficacy, depression and health-related quality of life according to musculoskeletal symptoms of the ordinary white-collar worker. The subjects of the study were 83 workers who were working D Health Center and Dgu office of Gwangju Metropolitan City and they were voluntarily interviewed with a use of organized questionnaire. Except the responses from three subjects whose responses were insincere of 102 ones were decided for the final analysis. The results showed that there were significant differences in all job stress, self-efficacy, depression and health-related quality of life according to musculoskeletal symptoms. Depression, self-efficacy, job stress were significantly correlated; however, health related to quality of life was not. Therefore, as the results indicate that job stress, self-efficacy, depression and health-related quality of life can be affected by musculoskeletal pain for office workers, there is a need for the development of programs focused on the prevention of musculoskeletal discomfort.

Rice (Oryza sativa) cultivars show an impairment of growth and development in response to abiotic stresses such as drought, salinity, heat and cold at the early seedling stage. The tolerance to heat stress in plants has been genetically modulated by the overexpression of heat shock transcription factor genes or proteins. In addition to a high temperature-tolerance that has also been altered by elevating levels of osmolytes, increasing levels of cell detoxification enzymes and through altering membrane fluidity. To examine the heat tolerance in transgenic rice plants, three OsOPT10 overexpressing lines were characterized through a physiological analysis, which examined factors such as the electrolyte leakage (EL), soluble sugar and proline contents. We further functionally characterized the OsOPT10 gene and found that heat induced the expression of OsOPT10 and P5CS gene related proline biosynthesis. It has been suggested that the expression of OsOPT10 led to elevated heat tolerance in transgenic lines.

The DNA-binding protein from starved cells (DPS), originally identified as a DNA binding protein in Escherichia coli, is known to play an important role in DNA protection. The aim of this study was to evaluate the functional roles of DPS in E. coli against various kinds of external stresses by comparing the properties of wild-type E. coli cells and dps knockout mutant E. coli (${\Delta}dps$) cells. Under various stress conditions, we measured the cell growth of the wild-type E. coli and the dps knockout mutant E. coli (${\Delta}dps$) cells using a UV spectrophotometer. The growth rate of the cells was compared to investigate the functional roles of the DPS protein in E. coli. In comparison to the properties of the wild-type E. coli cells, the dps knockout mutant E. coli (${\Delta}dps$) cells showed highly sensitive phenotypes under various stress conditions, such as heat shock, acidic pH, nutrient deficiency, and different concentrations of reactive oxygen species (ROS), suggesting that DPS plays key roles in E. coli in combating diverse external stresses. The DPS DNA-binding protein in E. coli plays crucial roles in bacterial cell growth and in the protection of the cells from environmental stresses by tightly binding and preserving their DNA molecules.

Due to the concentration of population in the city center, the aboveground structures are saturated, and the development of underground structures becomes important. In addition, it is necessary to apply the reinforcement construction method for the pillar part of the adjacent tunnel that can secure stability, economy, and workability to the site. In this study, the tunnel pillar reinforcement method using prestress and grouting was reviewed. There are various reinforcement methods that can compensate for the problems of the side tunnel, but as the tunnel pillar construction method using prestress and grouting is judged to be excellent in field applicability, stability, and economic feasibility, it is necessary to review the theoretical and numerical analysis of the actual behavior mechanism. Therefore, a scaled-down model experiment was conducted. The reduced model experiment was divided into PC stranded wire + steel pipe reinforcement grouting + prestress (Case 1), PC strand + steel pipe reinforcement grouting (Case 2), and no reinforcement (Case 3), and the displacement of the pillar and the earth pressure applied to the wall were measured. Through experiments, it was confirmed that the PC stranded wire + steel pipe reinforcement grouting + prestress method is the most excellent reinforcement method among various construction methods. It was judged that it could be derived.

Objectives : To identify the relationship between somatization, stress, depression, anxiety, and psychological symptoms risk for nurses working in the intensive care unit. Create clinical evidence of psychosomatic medicine research and complement the meaning of somatization. Methods : Seventy of the mental health checkups conducted by the National Mental Health Center among the nurses using tools including Perceived Stress scale, Fatigue Severity Scale, Patient Health questionnaire-15, Korean Beck Depression Inventory, Korean Beck Anxiety Inventory, and Symptom Checklist-90-Revision. Results : 12.9% of the patients experienced more than moderate somatization. There was no statistical relationship between somatization and psychological stress perception, but feeling of anxiety and decreased self-confidence were related to the level of somatization. The group with severe somatization experienced more depression and anxiety. The group with high physical fatigue also had no statistical relationship with psychological stress perception, but had an effect on the feeling of tension, stress, or decreased control. Physical fatigue level was increased by experience of depression, not by anxiety. For psychological symptoms the higher the level of somatization, the higher the obsession and hostility was explored. In the linear regression model, stress, depression, and anxiety accounted for 39.3% of somatization and 16.1% of physical fatigue symptoms. Conclusions : We can estimate the decrease in stress cognitive symptoms, accompanying depression and anxiety, compulsion and hostility as characteristics of somatization. The causal relationship between somatization and psychological symptoms cannot be confirmed in this study, but the interrelationships are observed, can be referred to mediation strategies.
