Objectives : The purpose of this study was to compare levels of parenting stress and efficacy in mothers of children suffering from attention-deficit hyperactivity disorder (ADHD) and internet addiction disorder (IAD), mothers of children with ADHD alone only, and those with normal children. Methods : Participants were composed of 25 mothers of children with ADHD and IAD, 35 mothers of children with ADHD alone, and 50 mothers of normal children. They completed the Parenting Stress Index (PSI) and Parenting Sense of Competence (PSOC). Results : In comparison with the mothers of normal children, the mothers of children with ADHD and IAD and the mothers of children with ADHD alone showed significantly higher levels of parenting stress and lower parenting efficacy. However, a comparison of mothers of children with ADHD and IAD with those of children with ADHD alone did not show any significant differences in their levels of parenting stress or efficacy. Conclusion : Mothers of children with ADHD, regardless of the presence of IAD exhibited a higher level of parenting stress and a lower level of parenting efficacy than mothers of normal children.

We fed high trypotophan diet(3.5% tryptophan/diet(w/w) to mice for 7 days and treated then with 3 hour immobilization(IMMB) stress to investigate tryptophan metabolism and immunomodulation. The levels of serum tryptophan, brain tryptophan, serotonin(5HT) and 5-hydroxyindoleacetic acid(5HIAA) in the tryptophan diet fed animals were higher than those of the normal diet fed animals. Feeding tryptophan supplemented diet to stressed animal significantly decreased the levels of serum and brain tryptophan and 5HT levels. However, the amount of 5HIAA which is the metabolite of serotonin was increased in brain. Plasma corticosterone level was increased by the stress in both groups but the degree of this increase was smaller in high tryptophan fed animals. The relative numbers of CD8+ T cells, CD4+ T cells and B cells in spleen were decreased in high tryptophan diet fed and stressed animals compared to control diet fed and no stressed animals. CD8+ T cells decreased more than CD4+ T cells. The decrease of CD8+ T cells in high tryptophan fed and stressed animals was similar to that in high tryptophan fed animals or normal diet fed and stressed animals. Stress and tryptophan supplement acted synergistically to decrease the number of B cells. This study suggests that stress and tryptophan supplement could modify the number of lymphocyte cells, and indicates that the interaction of stress and tryptophan supplement on immune fuction depends on the types of immune cells.

Purpose : This study aims to understand the effects of job-seeking stress on depression and self-esteem in college students majoring in health science. Methods : In this study, in order to measure college students' employment stress, depression, self-esteem, and social support, a measurement tool was used by modifying and supplementing the questionnaire to suit the purpose and method of this study. The subjects, 210 students (46 men and 164 women) enrolled in colleges located in Busan, had their scores on the Beck depression inventory (BDI), job-seeking stress scale, and self-esteem scale measured. Results : There was a positive correlation between all sub-variables of employment stress, and a negative correlation between employment stress and self-esteem. Additionally, a positive correlation was found between employment stress and depression, and a negative correlation was found between self-esteem and depression. The result taken from the job-stress scale showed that women experienced an overall higher level of stress than men while seeking jobs. Furthermore, in terms of the BDI, men exhibited a higher level of depression than women when subjected to job-seeking stress. Finally, the results from the self-esteem scale reveal that men exhibited less self-esteem than women. Conclusion : A comprehensive review of the study's findings suggested that women had greater job-seeking stress than men. Additionally, it found that, for men, job-seeking stress had a greater impact on depression levels and self-esteem. These results suggest that a higher level of job-seeking stress may lead to higher levels of depression and lower levels of self-esteem. It will be useful to conduct follow-up research by operating self-esteem and depression programs.

This study examined whether specific coping strategies for the university entrance examination stress are related to high school seniors' depression and whether these strategies moderate the relationship between additional life event stress and depression. A sample of 358 high school seniors reported their level of additional life event stress, coping strategies they were using to handle examination stress, and their levels of depression. Problem-focused coping strategies and affective-regulation coping strategies were found to be related to reduction in depression. And, coping with examination stress was found to be related to depression independent of the level of additional life event stress.

This study examined the relationships between children's stress about obsesity and depression. In order to expand the study on the relationships, special attention was given to the possible moderator effects of child's ego-resiliency. The subjects were 494 4th and 6th graders residing in Seoul. It was found that 6th grade children's stress about obesity and depression was higher more than 4th graders in every boys and girls. Otherwise, 4th grade children's ego resiliency more higher in girls, 6th grade children's ego resiliency more higher in boysn. Children's stress about obesity was significantly related with the levels of childre's depression. The results indicated that children's higher obesity stress was related to higher levels of children's depression. Children's ego resiliency were found to be a significant moderator of relationship between children's obesity stress and depression. These findings indicated that children's ego resiliency could fuction as a protecting factor for children who perceive obesity stress.

Rapid social change affects residential environments and this in turn creates new stimuli to which people have to adapt. These stimuli have been seen to increase stress levels. Therefore, dwellers in these environments try to reduce stress through various methods. The purpose of this paper is to: 1) identify the general trends of coping styles about residential environmental stress, 2) analyze the differences in socio-demographic characteristics and how the physical characteristics of buildings affect stress, find out how personal backgrounds affect stress levels and the ability to get rid of environmental-related stress. The subjects in this study consisted of people living in multi-family housing in Gwang-ju. The city is divided into 5 districts and used quota sampling. 324 housewives were surveyed from the households by self-administered questionnaires. The survey was conducted in December, 2006, after the questionnaire was revised based on the results of preliminary survey. After all the questionnaires were collected, the data was coded and analyzed using the SPSS 12.0 program.

In this study, stress relaxation tests were carried out by keeping silt type soil specimens under different strain levels. Decreases in the stress values with time data was collected to better understand the effect of the strain level on the relaxation properties of soil specimens. In addition, the stress relaxation effect on the uniaxial compressive strength (UCS) values of the specimens was investigated with a series of tests. According to the results obtained from this study, the UCS values of the silt specimens significantly vary as a result of the stress relaxation effect. The UCS values were determined to increase with an increase of relaxation strain level to a threshold value. On the other hand, the UCS values were found to be affected adversely in case of high stress levels at the initiation of the relaxation, which are close to the peak level.
