The purpose of this study was to examine the effect of stress types and coping styles on the relationship quality with mothers-in-law perceived by sons-in-law. The data was collected from 300 sons-in-law aged 20~49 by using a survey questionnaire. The main results of this study were as follows: first, factor analysis yielded 4 types of coping(cognitive understanding coping, avoidant coping, direct behavior coping, and indirect behavior coping) and 7 types of stress(despising poor ability and condition, interference in daily life, son-in-law discrimination, wife discrimination, uncomfortable interaction, differences in lifestyle, and excessive demand). Second, the total stress perceived by sons-in-law in the relationship with their mothers-in-law was affected by avoidant coping and cognitive understanding coping. Finally, the relationship quality between mothers-in-law and sons-in-law was influenced by avoidant coping, uncomfortable interaction stress, direct behavior coping, differences in lifestyle stress, son-in-law discrimination stress, interference in daily life stress, frequency of meeting, cognitive understanding coping, indirect behavior coping, and age. Consequently, it was confirmed that sons-in-law's coping styles with stress from their mothers-in-law was more influential than the amount of stress perceived by sons-in-law on the relationship quality with their mothers-in-law. Especially, 'avoidant coping' among 4 styles of coping and 'uncomfortable interaction stress' among 7 types of stress influenced the relationship quality between mothers-in-law and sons-in-law the most.

Purpose: The study aimed to identify factors influencing work-life balance in female service workers. Methods: A cross-sectional descriptive study was conducted with an online survey of 234 service workers using volunteer panels. Data were collected using a self-administered questionnaire from July 16 to 24, 2017. Major variables included work-life balance, resilience, emotional intelligence, job stress, and fatigue. Using the SPSS 24.0 program, descriptive statistics, t-test, ANOVA, correlation analysis, and multiple regression analysis were conducted. Results: The mean score of the work-life balance level of female service workers was $2.9{\pm}0.85$ on a total score of 6. A multiple regression analysis revealed that smoking, resilience, job stress and fatigue were statistically significant factors in the model (p<.001), with an explanatory power of 50.3%. Emotional intelligence was not significantly associated with work-life balance. Conclusion: The level of work-life balance was considerably low in female service workers. This study suggests that nursing interventions to enhance work-life balance are required at both the individual and organizational levels.

Purpose: This study was done to investigate the relationship between self esteem, stress, depression and school adjustment among adolescents who were victims of bullying and those who were not. Methods: The questionnaire included the Peer Victimization Scale (Callaghan & Joseph, 1995), Self-esteem Scale, (Rosenberg, 1965), Daily Hassles Questionnaire (Feiner, Ginter & Primavera, 1982) and Center for Epidemiological Studies-Depression (Radloff, 1977). Data from 738 questionnaires were analyzed using frequencies, means, ${\chi}^2$-test, t-test and logistic regression analysis with SPSS 14.0. Results: Victims of bullying accounted for 19.8% of the students. Significant differences were found for grade, school record, family living together, satisfaction with parents and satisfaction with friends between students who were victims of bullying and those who were not. Self esteem and school adjustment for the victims of bullying were lower than for those in the non-victim group, and stress and depression were higher. The logistic regression analysis revealed that school record, family living together, satisfaction with friends, self esteem, friend related stress, family related stress and depression were significantly associated with being a victim of bullying. Conclusion: The result of this study offer basic data for the development of intervention programs to prevent students becoming victims of bullying.

Ralstonia syzygii subsp. indonesiensis (Rsi, former name: Ralstonia solanacearum phylotype IV) PW1001, a causal agent of potato wilt disease, induces hypersensitive response (HR) on its non-host eggplant (Solanum melongena cv. Senryo-nigou). The disaccharide trehalose is involved in abiotic and biotic stress tolerance in many organisms. We found that trehalose is required for eliciting HR on eggplant by plant pathogen Rsi PW1001. In R. solanacearum, it is known that the OtsA/OtsB pathway is the dominant trehalose synthesis pathway, and otsA and otsB encode trehalose-6-phosphate (T6P) synthase and T6P phosphatase, respectively. We generated otsA and otsB mutant strains and found that these mutant strains reduced the bacterial trehalose concentration and HR induction on eggplant leaves compared to wild-type. Trehalose functions intracellularly in Rsi PW1001 because addition of exogenous trehalose did not affect the HR level and ion leakage. Requirement of trehalose in HR induction is not common in R. solanacearum species complex because mutation of otsA in Ralstonia pseudosolanacearum (former name: Ralstonia solanacearum phylotype I) RS1002 did not affect HR on the leaves of its non-host tobacco and wild eggplant Solanum torvum. Further, we also found that each otsA and otsB mutant had reduced ability to grow in a medium containing NaCl and sucrose, indicating that trehalose also has an important role in osmotic stress tolerance.

Purpose: The purpose of this study was to investigate the stress caused by having a senior in high school preparing for the college entrance examination, and coping methods of middle aged women in order to have a high quality of life. Method: The subjects of this study were 410 middle aged women. The data were collected by a structured questionnaire during September 5 to October 26, 2005. Result: The respondents' scores of stress were relatively low. The scores of stress perception related to 'studies record inactivity', 'a bad feeling because their sons and daughters are lazy', and worries about fatigue and health of their sons and daughters' were relatively high. The scores of the coping method related to 'affirmative thought and conduct', and 'sincerity it in the senior in high school student' were relatively high. In subjects with a higher degree(score$\geq$3) of stress caused by the senior student in high school the scores of coping methods related to 'projection', 'evasion', and 'perseverance' were relatively higher than the scores of coping methods of subjects with a lower degree (score<3) of stress. Conclusion: Based on the findings of this study, we should develop an integrated support program for middle-aged women. A place must be made where mothers will be able to discuss the education of their children such as on-line group community by mothers.

The main purpose of this study was to examine the mediating roles of mothers' psychological well-being and support/control in the relationship between maternal child-related stress and adolescents' school adjustment. Participants were 389 3rd grade middle school students and their mothers. Mothers completed questionnaires about child-related stress and psychological well-being. Adolescents completed scales of maternal controlling/supportive parenting and school adjustment. Results indicated that a direct effect of mothers' child-related stress on adolescents' school adjustment was not significant. However, mothers' psychological well-being and support/control mediated the relations between child-related stress and adolescents' school adjustment. A higher level of child-related stress in mothers was associated with a lower level of psychological well-being, followed by a lower level of adolescents' school adjustment. Mothers who reported a higher level of child-related stress tended to be less supportive and more controlling, which led to a lower level of school adjustment. These findings suggest the need for considering both maternal characteristics and parenting in explaining adolescents' school adjustment.

The purpose of this study was to investigate factors associated with coping responses in Korean public high school students. Methods: This study employed a descriptive survey research design. The sample included 263 high school students who responded to a self-report questionnaire. Variables included socio-demographic characteristics, health-related characteristics, academic stress, somatization symptoms, social support, and coping responses. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's correlations, and multiple regressions. Results: Participants, regarding their school life, reported moderate levels of academic stress ($M{\pm}SD=2.3{\pm}0.52$) and somatization symptoms ($M{\pm}SD=2.3{\pm}0.71$), and a relatively high level of social support ($M{\pm}SD=4.2{\pm}0.67$). All the variables were associated with the use of multiple coping responses. Active-cognitive coping ($M{\pm}SD=2.9{\pm}0.68$) was most frequently used, followed by active-behavioral coping ($M{\pm}SD=2.5{\pm}0.56$). and avoidant coping ($M{\pm}SD=2.3{\pm}0.75$). Significant relationships were found among the measured variables: positive relation between academic stress and somatization symptoms, but, negative between academic stress and both somatization symptoms and social support. Students who had higher stress and more somatization symptoms were more likely to use avoidant coping than the others. In multiple regression analysis, while factors associated with each coping response differed, gender appeared to be a significant factor in all methods. Variables included in the final model explained 27% of the variance in avoidant coping (F=11.40, p<.001). Conclusion: Based on the study results, schools should provide tailored educational programs to help high school students reduce multisource stress and somatization symptoms at school and cope with them in more active and effective ways.

The purpose of this study was to survey and diagnostic the self-related health cognition, stress, culture life and health-related fitness for residents of rural area. For this study, Total 126 people answered by a written questionnaire and took part in health-related fitness test for old adults in rural area. According to the normal distribution, the indexes were divided into five grades(very poor 5, poor 4, average 3, good 2, very good 1). The self-related health cognition(SF-36) was third grades. The index was as same as average old adults in rural area. The old adults stress level was third grades. The degrees of stress were as same as average old adults in rural area. The participation in the culture life was fourth grades. The health-related fitness test were third-fifth grades. The results of this experiment could be functioned as a very important fundamental source in order to establish satisfying health system, social welfare for the old people in rural area. Taken together, it seemed that self-related health cognition, stress level, participation in the culture life and health-related fitness have to be considered and improved. The indexes should be further investigated and some practical method should be developed for the olded people in rural area.
