Purpose: This study was designed to construct a structural model explaining depression in university students. Methods: Data were collected from 1,640 university students by questionnaire, and analyzed using AMOS 5.0 to test the hypothetical model. Results: Fitness statistics for the modified model were GFI=.93, AGFI=.89, NFI=.91, and RMSEA=.081. All the 12 paths in the modified model proved to be statistically significant. Depression of university students accounted for 52% of the covariance by the factors. The factor that had the most influence on depression was individual vulnerability, and followed by sequence order, stress, social support, coping, and self-efficacy. Depression was influenced directly by individual vulnerability, stress, social support, and coping, and indirectly by individual vulnerability, stress, social support, and self-efficacy. Conclusion: A screening and management system for the high risk group is needed to effectively prevent depression and reduce rate of depression in university students. Detailed support programs which specifically deal with prevailing stressors should be developed to effectively reduce the harmful effects of individual vulnerability and stress. It is anticipated that the model constructed in this study could be utilized as a reference in developing various strategies to prevent and intervene depression in university students.

Purpose: This study examined the effects of stress vulnerability and parental burnout on the mental health of women with early school-aged children, with a focus on the mediating role of spirituality. Methods: A survey was conducted among 171 women with early schoolaged children in Gyeonggi Province, Gangwon Province, and Seoul. Data were collected from September to December 2022 using the Korean-Symptom Check List 95, the Parental Burnout Assessment, and the Spirituality Assessment Scale. The data were analyzed using structural equation modeling with SPSS/WIN 22.0 and AMOS 20.0. Results: The study model demonstrated a good fit, explaining 40.5% of the variance in mental health through stress vulnerability, parental burnout, and spirituality. Spirituality had a significant direct impact on mental health. Additionally, participants' spirituality directly influenced their mental health, while stress vulnerability and parental burnout indirectly affected their mental health and were mediated through spirituality. Conclusion: Stress vulnerability and parental burnout are negatively associated with mental health, while spirituality partially mediates these effects. Implementing a program to promote spirituality is suggested to assist mothers in recognizing the value and meaning of parenting activities during nursing interventions for mental health.

Purpose: The purpose of this study was to investigate perceived stressor, the characteristics of personality and stress responses of college students and to compare their gender differences. Method: This study was cross-sectional survey and participants were 146 college students. Data was collected by Perceived Daily Life Stressor Scale of college students, Lim's Character Style Inventory, Vulnerability of Personality, and Stress Response Index, demographic questionnaire from May to September, 2012 in two cities. Results: Friend relationship stressor(p=.024) and professor relationship stressor(p=.032) among daily life stressors of female students were significantly higher than male students. Fatigue(p=.009), anger(p=.046), somatization(p<.001) and total stress response(p=.049) of female students were significantly higher than male student. Challenge(p=.034) of LCSI of female students was significantly higher than male student and stability(p=.018) of male students was significantly higher than female students. Regression model of stress response in male college students was significant(F=35.18, p<.001) and influencing factors were vulnerability of personality and challenge($R^2$=.544). Regression model of stress response in female college students was significant(F=39.38, p<.001) and influencing factors were vulnerability of personality, perceived stress type, and sociability($R^2$=.612). Conclusion: These findings need to be reflected to develop stress management programs and mental health promotion programs for college students.

Objective Personality traits can be the basis for individual differences in the biological response of stress. To date, many psychobiological studies have been conducted to clarify the relationship between personality and biological reactivity to stress. This review summarizes the most important findings in this area of research. Results Key findings related to the relationship between personality factors and stress-sensitive biological systems in four research models have been summarized; model of psychosocial characteristics, model based on Rumination and Emotional Inhibition, Eysenck's biopsychological model, and Five-Factor Approach of Personality. Conclusion According to the results of this review, it can be concluded that personality typology of individuals influenced their biological reactivity to stressful events. Understanding the biological basis of personality can help to better understand vulnerability to stress. Future research can be continuing based on framework of the four models.

This research investigated the moderating effects of children's negative emotionality, activity and sociability on the relation between maternal parenting stress and children's behavior problems. Participants consisted of 1,667 preschool children from the fifth wave of the Panel Study on Korean Children. EAS was used to measure the children's temperament. Mothers reported parenting stress and children's behavior problems. The results revealed that the magnitude of association between relation between maternal parenting stress and children's behavior problems was greater for high levels of negative emotionality and activity as well as low levels of sociability. The results support a diathesis-stress model in which high negative emotionality, activity and low sociability confer vulnerability for preschool children in a high stress family.

The investigation on possible causes of failures related to documented collapses is a complicated issue, primarily due to the scarcity and inadequacy of information available. Although several studies have tried to understand which are the inherent structural deficiencies or circumstances associated to failure of the main structural elements in a reinforced concrete frame, to the authors knowledge a uniform approach for the evaluation building static vulnerability, does not exist yet. This paper investigates, by means of a detailed case study, the potential failure mechanisms of an existing reinforced concrete building. The linear elastic analysis for the three-dimensional building model gives an insight on the working conditions of the structural elements, demonstrating the relevance of a number of structural faults that could sensibly lower the structure's safety margin. Next, the building's bearing capacity is studied by means of parametric nonlinear analysis performed at the element's level. It is seen that, depending on material properties, concrete strength and steel yield stress, the failure hierarchy could be dominated by either brittle or ductile mechanisms.

Central to developing new treatment strategies for late onset sporadic Parkinson's disease (PD) and early onset familial PD is resolving the enigma of the specific vulnerability exhibited by substantia nigra dopamine (DA) neurons despite multiple risk factors. Neuropathological evidence from both human and experimental models of PD firmly supports a significant role for oxidative stress (OS) and mitochondrial dysfunction in the death of nigral DA neurons. Largely unknown are the genes underlying selective susceptibility of nigral DA neuron to OS and mitochondrial dysfunction and how they effect nigral DA cell death. To overcome the paucity of nigral DA neurons as well as the dilution effect of non-DA cells in brain tissues, we have developed wild type DA cell line model, SN4741 and mutant DJ-1 (-/-) DA cells, appropriate for microarray analysis and differential mitochondrial proteomics. Mutations in the DJ-1 gene (PARK7), localized in cytoplasm and mitochondria, cause autosomal recessive early onset PD. Through microarray analysis using SN4741 cells followed by validation tests, we have identified a novel phylogenically conserved neuroprotective gene, Oxi-a, which is specifically expressed in DA neurons. The knockdown of the gene dramatically increased vulnerability to as. Importantly as down-regulated the expression level of the gene and recovery of its expression via transient transfection exerted significant neuroprotection against as insult. We also have identified altered expression of mitochondrial proteins and other familial PD genes in DJ-1 (-/-) mutant cells by differential mitochondrial proteomics. In DJ-1 (-/-) cells the knockdown of the other familial PD genes (Parkin and PINK1) dramatically increased susceptibility to as. Thus, further functional characterization of the Oxi-$\alpha$ gene family and the mitochondrial alteration in the DJ-1 (-/-) cell model will provide the rationale for the neuroprotective therapy against both sporadic and familial PD.
