Economic activity and social participation by women has recently increased; however, working mothers raising young children are under new stress due to the simultaneous combination of job and parenting responsibilities. This stress has resulted in social problems of career break and low fertility. This study investigates the effect of clinical art therapy on occupational stress and parenting stress of working mothers. We analyzed 34 working mothers in full-time employment (over 8 hours a day) who have preschool children (0-6 years old). They were divided into 17 subjects in the experimental group and 17 subjects in the control group. For the experimental group, 10 hours and a half sessions of group art therapy were participated in once a week from April to August in 2014. We perform Dan Occupational Stress Index by Ivancevich and Matteson, Parenting Stress Index/Short Form and salivary cortisol test before and after the group art therapy. For qualitative analysis, Kinetic House-Tree-Person (KHTP) drawing test was used. Using SPSS ver. 19.0, paired t -test or Wilcoxon signed rank test compared the pre and post analysis results. The results of this study are as follows. First, scores of 'occupational stress factor' subpart showed significant improvement in the Occupational Stress Index after the clinical art therapy. Second, scores of 'parental distress,' 'parent-child dysfunctional interaction,' and 'difficult child' subpart in Parenting Stress Index also showed a significant improvement. Third, a positive change was observed after the clinical art therapy in the KHTP drawing test. In conclusion, this study suggests that the clinical art therapy can be effective for occupational stress factors and the parenting stress of working mothers.

The purpose of this study was to examine the relationship between parenting stress, social support and the social development of preschool children in rural areas. The subject included 114 preschool children, along with their mothers, selected from kindergartens and day care centers in rural areas. The instruments included the parenting stress index, social support inventory and the social maturity scale. The statistics used from this data were t-test, one-way ANOYA(Scheffe test), correlation analysis and multiple regression analysis. This study showed that maternal parenting stress was influenced significantly by the related variables; gender of child, birth order of child, age of mother, educational attainment of mother, family income, religion, family type. And also, social support was influenced significantly by the above variables. The child's social development was influenced significantly by the variables that related child and the family. Correlation analysis indicated that parenting stress and social development of the child were relatively negative high correlation coefficients. And social support and social development of the child were relatively positive high correlation coefficients. The important factors on predicting social development of the child were found to be birth order of child, age of mother, educational attainment of mother, family income, religion, family type, daily stress, stress of difficult child, stress of parent-child dysfunctional interaction, educational distress, husband support, and other support. Especially stress of difficult child and husband support were important variables that predicted the social development of the preschool children.

T cells play a key role in viral infection. However, in patients with chronic hepatitis C virus (HCV) infection, HCV-specific T cells are dysfunctional and impaired in the liver, which is the primary site for HCV replication. There are multiple potential mechanisms for HCV-specific T cell dysfunction including induction of immune inhibitory pathways (program death-1; PD-1, cytotoxic t lymphocyte associated antigen-4; CTLA-4) and immune tolerance induced specific for the liver. However, the interaction between hepatocytes and HCV-specific CD8 T cells has not clearly established. In this study, we confirmed huh (human hepatoma) 7.5 cells expressing HLA (human leukocyte antigen) A2 presented antigen to activate HCV-specific CD8 T cells in HLA A2-restricted manner and expression of PD-L (program death ligand) 1 on huh7.5 cells reduced HCV-specific CD8 T cell activation, suggesting an immune modulatory activity. Loss of HCV-specific tetramer responses following antigenic stimulation correlated with increased caspase-3 activity. In addition, PD-L1 on huh7.5 cells rescued HCV-specific CD8 T cells from apoptosis. Our results suggest that the interaction between PD-L1 and PD-1 can recover the function of HCV-specific CD8 T cells in the liver, which could be applied in therapy of HCV chronic infection.

Objective:The aim of this study was to evaluate the relationship between sustained attention deficits in Attention-Deficit/Hyperactivity Disorder(ADHD) children and short-term Heart Rate Variability(HRV) parameters. In addition, we evaluate the relationship between The ADHD rating scale(ARS), the computerized ADHD diagnostic system(ADS) and Parenting stress index- short form(PSI-SF). Methods:This study was performed in the department of children and Adolescent psychiatry, Korea university Guro hospital from august 2008 to January 2009. We evaluated HRV parameters by short-term recordings of 5 minutes. K-ARS and ADS are used for screening and identifying ADHD children. Intelligence was measured using Korean educational Developmental Institute-wechsler Intelligence Scale for Children. The caregivers Complete Parenting Stress Index scale for evaluation parent stress. Results:The low frequency(LF) was significantly correlated with response variability of ADS. However, the other variables of ARS and ADS were not significantly correlated with LF. Hyperactivity subscale of ARS was significantly correlated with parental distress subscale and difficult child subscale of PSI-SF and inattention subscale of ARS was also significantly correlated with dysfunctional interaction and difficult child subscale of PSI-SF. Conclusion:The LF, 0.10-Hz component of HRV is known to measure effort allocation. This study shows that the LF component of HRV is significantly correlated with the response variability of ADS. This means that more severe symptoms of ADHD were correlated with the increase in the LF that means decreased effort allocation. These results also support the clinical usability of HRV in the assessment of ADHD. Furthermore, PSI-SF is correlated with hyperactivity and inattention variables of ARS.
