Using 492 older people in Chuncheon, this study examines whether social support is associated with depression of older people. Findings show that stress is positively associated with depression. Social support is negatively related to depression of older people. Analysis on the sources of social support reveals that all of the supports from families, friends, and important others are negatively associated with depression of the elderly. However, buffering effects of social support is not confirmed. Depression of older people is also associated with gender, household type, economic activity participation, and chronic diseases. Based on the findings, this study provides suggestions to prevent depression of older people and future research agenda.

The aim of this study was to assess the degree of association between individual stress and the amount of smoking among male senior students of a medical college. The questionnaire survey was conducted twice for collecting the data on stress level in terms of BEPSI score, smoking amounts, alcohol intake, and residence type in 1992 and 1993. Among the 223 responders, 39.9% were smokers. In the smokers, the association between stress level and smoking amount was significant after controlling for alcohol intake and residence type (p<0.1). Especially in the group of living without family, the association was more significant (p=0.06). Therefore, it is recommendable that the stress management program is called upon for the student smokers to reduce smoking amount.

The purpose of this study was to examine effect of locus of control and self-efficacy on stress of selected dental hygiene students. This study provides basic data to develop a method to reduce stress. The students of A women's college in Kyungi province majoring in dental hygiene were asked to answer the locus of control scale, self-efficacy scale, and stress level. As a result, this study concluded the following findings: 1. Locus of control scale was 8.77 and it meant the students used internal control. Self-efficacy scale was beyond median. In stress level category, mean of stress was 2.32, stress with friends was 2.05, stress with money was 2.33, stress with course in life was 2.29, stress with family members was 2.24, stress with study was 2.95. 2. Stress had negative relations with locus of control and self-efficacy. There was a positive relation between locus of control and self-efficacy. 3. Effect of self-efficacy on stress was significantly negative but effect of locus of control on stress was insignificant. In subscale, effect of self-efficacy and locus of control on stress with study was insignificant. 4. Indirect effect of locus of control on stress was statistically significant. The students with internal locus of control showed high self-efficacy and the students with high self-efficacy showed low stress level. In conclusion, educators should make an effort to reduce stress of students and understand the factors related to stress.

This study examined effects of Enterobacter ludwigii SJR3 showing a high 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity, on growth of tomato plant and its expression of stress-related genes under drought and salt stress. SJR3 strain was inoculated at $10^6cell/g$ soil to 4-week grown tomato plants, and drought and salt stresses were treated. After additional incubation for 1 week, root length, stem length, fresh weight and dry weight of tomato plants treated with SJR3 increased by 37.8, 37.2, 96.8 and 146.6%, respectively compared to those of uninoculated plants in drought stress environment, and they increased by 19.2, 25.4, 19.5, and 105.8%, respectively in salt stress environment. Proline content in tomato leaves increased significantly under stress conditions as one of a protecting substance against stresses, but proline contents in tomato treated with SJR3 decreased by 62.1 and 54.1%, respectively. Relative expression of genes encoding ACC oxidase, ACO1 and ACO4, ethylene response factor genes ERF1 and ERF4, and some other stress-related genes were examined from tomato leaves. Compared to the non-stressed tomato, expressions of all stress-related genes increased significantly in the stressed tomato, but gene expressions in the inoculated tomato were similar to those of no-stressed control tomato. Therefore, E. ludwigii SJR3 may play an important role in mitigating drought and salt stress in plants, and can increase productivity of crops under various abiotic stresses.

The purpose of this study is to identify the effects of stress and sleep quality on depression during clinical practice of nursing students. The subjects of the study were third and fourth graders who experienced clinical practice for more than a semester among nursing students at C University in one region. A total of 107 people were analyzed. Most of the nursing students experienced more than moderate stress and depression during clinical practice, and the quality of sleep was low. During clinical practice, the stress of nursing students showed a weak correlation with the quality of sleep(r=.393, p<.001), and depression showed a strong net correlation with stress(r=.588, p<.001), the quality of sleep(r=.591, p<.001). Factors affecting depression during clinical practice were stress and the quality of sleep. Therefore, effective management methods that can relieve the stress of nursing college students during clinical practice and improve the quality of sleep and active nursing strategies that can prevent depression should be sought.

This study aims to suggest the direction for improving the mental health of married women by analyzing the relationship between married women's life stress, life satisfaction, self-elasticity, and coping stances. For this study, 200 married women in their 30s~60s living in Seoul, Incheon, and Gyeonggi-do were surveyed on January 2~15, 2020, and the results were analyzed using multiple regression and regression analysis. As a result of the study, it was found that the main causes of life stress felt by married women were economic problems, relationships with their children, and conflict between mother in law and daughter in law. By analyzing the relationship with life satisfaction, it turned out that life stress had a relationship with life satisfaction, which affected the decline in their life satisfaction. In addition, it was verified that the self-elasticity and coping stances had a partial mediating effect in the relationship between the life stress and life satisfaction of married women. Accordingly, improving self-elasticity and coping stances will likely reduce the life stress of married women and boost their life satisfaction.

This study investigated the relationships between stress-coping strategies and the mental health of college students from health related and non-health related departments by developing an efficient managerial indicator using student lifestyle guidance and employment guidance. Results indicated that there are differences in stress factors between general characteristics and departments. Hope management was used the most for stress-coping strategies for health related departmental students and emotional management was used the most for stress-coping strategies for non-health related departmental students. Compulsion scored high for health related departmental students in regards to mental health while fear and hostility scored high for non-health related departmental students. Results also showed that active stress-coping strategies and paranoia were negatively correlated, while passive stress-coping strategies and many mental health substructure were positively correlated. In conclusion, negative influences on mental health is the reason for instances where stress-coping strategies were not pertinent. Therefore colleges and professors should consider developing a program which can appropriately manage and regulate college students stress and thereby allow students to actively participate with benefits from college lifestyle guidance and employment guidance.

We have investigated the effects of abiotic and biotic stresses on leaf senescence using transgenic tobacco plants, in which cellular contents of polyamines were increased by introducing the genes of polyamine and ethylene biosynthesis in sense or antisense orientation. These transgenic plants showed accumulations of polyamines at higher levels than were found in wild-type. Stress-induced senescence was attenuated in transgenic plants cpmpared with wild-type plants, in terms of total chlorphyll loss and phenotypic changes after oxidative stress of hydrogen peroxide($H_2O_2$), high salinity, acid stress (pH3.0), ABA and fungal pathogen(phytophothora parasitica pv.Nicotianae). Transcripts for antioxidant enzyme, glutathionine-S-transferase and catalase, were also more abundant in transgenic plants than wild-type plants. These result suggested that higher expression of those genes caused a broad-spectrum resistance to abiotic stress/biotic stress. These phenomena indicate that polyamines may play an important role in contributing to the antioxidant defense function in plants. Our findings suggest that facilitate the improvement of stress tolerance of crop plants.
