This study examined the characteristics of children, parents, family, and the extra context related to the parenting stress of employed and unemployed mothers from a broader perspective. The subjects were 323 employed mothers 3nd 300 unemployed mothers of pre-school age children. Parenting stress due to the role of being a parent for both employed and unemployed mothers was correlated with the chid's activity level, husband support, quality of life, available social support, and satisfaction of early childhood program's location. Parenting stress due to child-rearing of both employed and unemployed mothers was correlated with child's birth order, activity level and rhythmicity of child, husband support, quality of life, available social support, and satisfaction of early childhood program. Number of children was the strongest predictor of parenting stress due to the role of being a parent for employed mothers and the child's activity level for unemployed mothers. Besides, the child's activity level was the strongest predictor of parenting stress due to child-rearing for both employed and unemployed mothers.

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.

This experiment was carried out to examine the roles of selenium in arsenic- and chromium-induced oxidative stress, which results in chromosomal damage, such as sister chromatid exchange (SCE) and chromosomal aberration (CA). For this purpose, the frequency of CA and SCE related to the level of 0xidative stress were analyzed. Selenium decreased the frequency of CA induced by As. In order to evaluate the effect of selenium on clastogenic factors, media from As- and Cr-treated cells were ultrafiltered and added again to cells in the presence or absence of selenium. Selenium decreased the frequency of SCE by As and Cr. This observation indicates the possibility of presence of clastogenic factor. In addition, the clastogenic factor would be involed in oxidative stress since selenium decreased the level of oxidative stress. Thus, it is suggested that selenium may play a role as an anti-clastogenic effector by preventing the oxidative stress, thereby decreasing the frequency of Asand Cr-induced chromosomal damage.

Purpose: The purpose of this study is to investigate the role of social support in the experience of job stress among hospital nurses. Method: This study was carefully designed to overcome methodological shortcomings found in past research, and examined two organizational effectiveness variables(job satisfaction and organizational commitment) as outcome variables. The sample used in this study consisted of 602 nurses from 5 general hospitals. Data were collected with self-administered questionnaires and analyzed using hierarchical regression and LISREL technique. Result: It was found that: (a) three job stress variables(workload, role conflict and conflict with other medical staff) have negative effects on job satisfaction and organizational commitment; (b) social support have positive main effects on the two output variables; (c) the negative effects of job stress variables on job satisfaction and organizational commitment are not buffered by social support, and (d) social support mediates the effects of job stress on job satisfaction and organizational commitment, and the size of the mediating effects is small. Conclusion: Further research needs to be done to further refine this study.

Purpose: This study was to investigate the stress of parents while they were rearing their children. Method: This study reviewed the preceding research related to parents' stress and breeding stress with consideration of modem society, family system and parents' role. Results: In the parent-child relationship, parents feel stressed when they found it difficult to come up with an expectation to the parents' role of rearing child. Therefore, considering the health of parents and children, it is important to mediate parents who are under stress. Moreover, since parents cannot handle this problem all alone, it should be discussed and solved not only by individual but also by family, and further by social context. The parent-child relationship in early infancy is a core element to the development of an individual. Parents have influence on a child's development the most and play a big role. In particular, many parents these days believe that parent-child relationship is changing in a democratic way and a couple breeds their child together. However, in reality, the relationship has not been changed and is even regarded as more difficult situation than it was in the traditional society. Parents are oppressed with not being adapted to social changes and advance, and child also feels the same. Conclusion: Parents need education and support for child rearing without having any stresses. Health care provider consider this issues and to build a healthy parent-child relationship by helping parents.

This study examined to find out mediating variable between ordinary stress and anxiety-depression. The subjects were 2,844 4th grade elementary school in Korea. The instruments used were questionnaires about anxiety-depression, ordinary stress, anger control ability and negative self-concept. Data were analyzed by t-test and regression. Major findings were as follows: (1) There were significant difference in parent-, appearance-, possession-related stress, anger control ability, negative self-concept and anxiety-depression according to sex. (2) Parent-, schoolwork-, peer-, appearance-related stress and anger control ability had a significant effect on the anxiety-depression. The principal finding was that anger control ability had mediating role between ordinary stress(schoolwork-, peer-, appearance-related stress) and anxiety-depression in male, one side parent-related stress and anxiety-depression in female. (3) Parent-, schoolwork-, peer-, appearance-related stress and negative self-concept had a significant effect on the anxiety-depression. The principal finding was that negative self-concept had mediating role between ordinary stress(parent-, schoolwork-, peer-, appearance-, possession-related stress) and anxiety-depression in male, one side parent-, peer-related stress and anxiety-depression in female.

The purpose of this study was to contribute to maternal nursing in early postpartum stage and to neonatal nursing. Data were collected through self-report questionnaires which were constructed to include parental role stress scale, state-trait anxiety scale, and perception of the newborn scale. The subjects consisted of 100 mothers in the early postpartum stage at three hospitals in the Kyoung-In area, from November 8 to December 26, 1997. The data were analyzed by an SPSS program. The results are as follows ; 1. The mean of parental role stress of mothers in the early postpartum stage was 10.70$\pm$2.63. The means of state anxiety and trait anxiety of mothers were 36.29$\pm$8.45 and 38.53$\pm$8.36. The mean of perception of the newborn was 2.65$\pm$5.05, and 59% of mothers rated their newborn as better than the average newborn. 2. The level of parental role stress correlated to the level of state anxiety and trait anxiety. The level of state anxiety and trait anxiety were also related. The level of perception of the newborn was related to the level of state anxiety and trait anxiety. 3. Mothers who did not want the pregnancy, whose newborns were girls, and who already had one child had higher state anxiety than those who did not. Mothers who already had one child, and whose newborn had no specific signs had higher trait anxiety than those who did not. Mothers who professed a religions had a higher perception of the newborn than those who did not. The above findings indicate that the levels of parental role stress, state anxiety, trait anxiety and perception of the newborn of mothers in early postpartum stage were correlated. Therefore nursing intervention for reducing stress and anxiety, and improving perception of the newborn should be provided for mothers in early postpartum stage.

The main purpose of this study was to examine the relationship among co-parenting, maternal parenting stress, and preschoolers' anxiety and hyperactivity with a sample of 155 mothers with 3 to 4 year old children (83 boys and 72 girls) living in Seoul. They completed a questionnaire on co-parenting, maternal parenting stress, and preschoolers' anxiety and hyperactivity. The results were analyzed by means of correlations and regressions. Co-parenting was positively correlated with preschoolers' anxiety and hyperactivity but affectionate, integrated co-parenting was negatively correlated with preschoolers' anxiety and hyperactivity. Maternal stress of parental suffering, dysfunctional interaction, and difficult temperament were positively related to preschoolers' anxiety and hyperactivity. Conflicting co-parenting was positively correlated with maternal stress of parental suffering, but affectionate and integrated co-parenting was negatively correlated with maternal stress of parental suffering and difficult temperament. Furthermore, maternal parenting stress mediated the relationship between co-parenting and preschoolers' anxiety and hyperactivity. Especially, maternal stress of parental suffering tended to play a perfectly mediating role between conflicting and integrated co-parenting and preschoolers' anxiety, between conflicting co-parenting and preschoolers' hyperactivity. Maternal stress of difficult temperament tended to play a perfectly mediating role between integrated co-parenting and preschoolers' anxiety and between conflicting co-parenting and preschoolers' hyperactivity. These results clearly indicate that maternal parenting stress plays a crucial role in the levels of preschoolers' anxiety and hyperactivity.

In this study, we analyzed the oxidative stress response of wblA ($\underline{w}$hi$\underline{B}$-$\underline{l}$ike gene $\underline{A}$, SCO3579), which was previously shown to be a global antibiotic down-regulator in Streptomyces coelicolor. Ever since a WblA ortholog named WhcA in Corynebacterium glutamicum was found to play a negative role in the oxidative stress response, S. coelicolor wblA has been proposed to have a similar effect. A wblA-deletion mutant exhibited a less sensitive response to oxidative stress induced by diamide present in solid plate culture. Using real-time RT-PCR analysis, we also compared the transcription levels of oxidative stress-related genes, including sodF, sodF2, sodN, trxB, and trxB2, between S. coelicolor wild type and a wblA-deletion mutant in the presence or absence of oxidative stress. Target genes were expressed higher in the wblA-deletion mutant compared with wild type, both in the absence and presence of oxidative stress. Moreover, expression of these target genes in S. coelicolor wild type was stimulated only in the presence of oxidative stress, suggesting that WblA plays a negative role in the oxidative stress response of S. coelicolor, similar to that of C. glutamicum WhcA, through the transcriptional regulation of oxidative stress-related genes.

The purpose of this study was to determine the relationship between job stressors (role conflict, role ambiguity, and role overload), innovation behavior, and mindfulness in organizational employees and to examine the moderating effect of mindfulness on the relationship between job stressors and innovation behavior. For this purpose, data were collected and analyzed through a structured questionnaire from 337 employees of companies and organizations. The results of the study showed that job stress has a negative effect (-) on innovation behavior and mindfulness has a positive effect (+) on innovation behavior. Mindfulness was found to play a moderating role in the relationship between job stress and innovation behavior. Therefore, mindfulness is identified as an individual resource and competency that can mitigate job stress and promote innovative behavior, and organizations should provide training to harness and enhance mindfulness to control job stress and increase innovative behavior.
