The purpose of the study was to carry out research on the work-related stress of child care teachers in employer-supported child care centers. Four-experienced child care teachers were designated for this research, and then data were collected through narrative research. In this study, work-related stress of child care teachers in employer-supported child care centers was found to be of the following types, "laborious oneself caused by the prolonged working environment", "fears about non-permanent employment status", and "a huge mountain named parents work". Research findings were discussed in term of the implication of understanding teacher' work-related stress.

This purposes of study are to examine the effect of family related stress and social support on the ways of coping of adolescents and provide a ground necessary to improve it. A survey was conducted on 756 adolescents who were living in Naju. Collected data were analyzed by descriptive statistics, Pearson's correlation, and multiple regression analysis. This study utilized two different models, direct effect model and buffering effect of social support in order to examine the effects of social support on the ways of coping of adolescents. Research findings suggest that the level of coping appeared to be low in general among adolescents. The finding of direct effect model of social support was that mother's support, father's support, sibling's support, lather's grade, mother's grade, and economic level effected the ways of coping of adolescents. But it was not empirically supported that the social support buffered the family related stress on the ways of coping. In other words, the effects of family related stress factor didn't decrease with the increase in the level of social support, however the level of coping increased at a mercy of the age and economic level. Finally, this paper attempted to provide some alternatives to effectively improve the ways of coping among adolescents based on empirical findings.

Korean ginseng (Panax ginseng) has long been cultivated as an important economic medicinal plant. Owing to the seasonal and long-term agricultural cultivation methods of Korean ginseng, they are always vulnerable to various environmental stress conditions. ABSCISIC ACID (ABA) is an essential plant hormone associated with seed development and diverse abiotic stress responses including drought, cold and salinity stress. By modulating ABA responses, plants can regulate their immune responses and growth patterns to increase their ability to tolerate stress. With recent advances in genome sequencing technology, we first reported the functional features of genes related to canonical ABA signaling pathway in P. ginseng genome. Based on the protein sequences and functional genomic analysis of Arabidopsis thaliana, the ABA related genes were successfully identified. Our functional genomic characterizations clearly showed that the ABA signaling related genes consisting the ABA receptor proteins (PgPYLs), kinase family (PgSnRKs) and transcription factors (PgABFs, PgABI3s and PgABI5s) were evolutionary conserved in the P. ginseng genome. We confirmed that overexpressing ABA related genes of P. ginseng completely restored the ABA responses and stress tolerance in ABA defective Arabidopsis mutants. Finally, tissue and age specific spatio-temporal expression patterns of the identified ABA-related genes in P. ginseng tissues were also classified using various available RNA sequencing data. This study provides ABA signal transduction related genes and their functional genomic information related to the growth and development of Korean ginseng. Additionally, the results of this study could be useful in the breeding or artificial selection of ginseng which is resistant to various stresses.

Gene-expression analysis is increasingly important in biological research, with real-time reverse PCR (RTPCR) becoming the method of choice for high-throughput and accurate expression profiling of selected genes. However, this technique requires important preliminary work for standardizing and optimizing the many parameters involved in the analysis. Plant stress studies are more and more based on gene expression. The analysis of gene expression requires sensitive and reproducible measurements for specific mRNA sequence. Several genes are regulated in response to abitoic stresses, such as salinity, and their gene products function in stress response and tolerance. The design of the primers and TaqMan probes for real-time PCR assays were carried out using the Primer $Express^{TM}$ software 3.0. The PCR efficiency was estimated through the linear regression of the dilution curve. To understand the expression pattern of various genes under salt stressed condition, we have developed a unique public resource of 9 stress-related genes in poplar. In this study, real-time RT-PCR was used to quantify the transcript level of 10 genes (9 stress-related genes and 1 house keeping gene) that could play a role in adaptation of Populus davidiana. Real-time RT-PCR analyses exhibited different expression ratios of related genes. The data obtained showed that determination of mRNA levels could constitute a new approach to study the stress response of P. davidiana after adaptation during growth in salinity condition.

The main purpose of this study was to examine the relations between Children's stress, self-esteem, and subjective well-being with a sample of 320 elementary school 5th graders (of which 161 were boys and 159 were girls) living in Seoul. They completed questionnaires on Children's stress, self-esteem, and subjective well-being. The results were analyzed by means of Pearson's correlation coefficients and regressions. It was observed that children's stress of studying/mother was negatively related to subjective well-being. Children's self-esteem was positively related to subjective well-being. Children's stress of studying/mother was negatively related to self-esteem. Self-esteem tended to play a perfectly mediating role between children's stress of studying/mother and subjective well-being. These results clearly indicate that children's self-esteem plays a crucial role in improving the levels of children's subjective well-being.

Purpose: The purpose of the study was to examine the meditating effect of unconditional self acceptance on the relationship between life stress and depression in nursing students. Methods: Data was collected from a survey of 140 nursing students using self-reported questionnaires. The data was analyzed using IBM SPSS Statistic 25.0. The mediating effect of unconditional self-acceptance on the relationship between the subject's life stress and depression was analyzed using Baron and Kenny's method. In addition, the Sobel test was conducted to determine the significance of the mediating effect. Results: The regression model explained 43% of the variance in nursing students' depression. Significant factors were task-related life stress, unconditional self acceptance, and academic achievement. Unconditional self acceptance had a partial mediating effect on the relationship between nursing students' task-related life stress and depression. Conclusion: To prevent depression in nursing students, it is necessary to build effective strategies to manage task-related stress and improve unconditional self-acceptance.

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.

This study investigates the mediate effects of obesity stress on the relationship between the narcissism and clothing behavior related appearance. The subjects for the study were 322 women aged 20's-30's in an online survey. Data analyses were conducted with SPSS 18.0 program. The study results are as follows. First, clothing behavior and obesity stress of plus size consumers are more affected by perceived obesity than BMI, and covert narcissistic tendency is stronger than overt narcissistic tendency. Second, the factor analysis results on narcissistic tendency indicated 'self-enhancement narcissism', 'self-initiative narcissism', and 'other-dependent narcissism'. Third, 'self-enhancement narcissism' more influenced 'fashion orientation' versus the greater influence of 'self-initiative narcissism' and 'other-dependent narcissism' on 'depending on clothing'. Fourth, the narcissistic tendency perceived by plus size consumers affect 'depending on clothing' and 'fashion orientation' with obesity stress as the mediator. 'Self-enhancement narcissism' and 'self-initiative narcissism' are partially mediated by obesity stress, and 'other-dependent narcissism' are completely mediated and affect appearance management behavior.

Objective : To investigate the sources, extent and related factors in South Korean doctors. Methods : The study subjects were 934 doctors in Taegu, Kyungpook Province, Korea(540 independent practitioners, 105 employed at hospitals and 289 residents in training). Information concerning job stress was obtained using a 9-item questionnaire. Information regarding related factors such as demographic characteristics(age, sex, marital status), perceptions on the socioeconomic status of doctors and working conditions(work time, on-call days per week) was also obtained by self-administered questionnaire during April and May, 2000. Results : Major sources of job stress included clnical responsibility/judgement factor, patient factor and work loading factor. The job stress score of residents was the highest among three groups. The score was lower in older doctors. The score was low among those who thought doctors' socioeconomic status was not good. The longer the work time, the higher the job stress score was. Multiple regression analysis was conducted to control for the mutual influence of independent variables. In regression analysis, the score of residents was higher than practitioners. Work time and socioeconomic status perception had negative effects on job stress score. Conclusion : The average job stress score of the doctors was high. Age, work type, working conditions and perceptions of socioeconomic status were found to besignificantly related to job stress score. Although the job stress of doctors is somewhat inevitable due to the nature of the doctor's job, control of work time, development of coping tools and other intervention methods are needed to reduce job stress of doctors. Further studies are required to understand the characteristics of iob stress and reduce the job stress of doctors.
