Objective: This study describes the change of operator performance in drastic change of illumination level, and proposes an alternative method to cope with it. Background: The control standard of illumination for nuclear power plants(NPPs) is based on the set of limit criteria for maintaining a specific illumination level. However, there is a possibility to cause human errors according to the psychological and physiological influences to operators in the situation of drastic change of illumination such as SBO(Station Black Out), so a basic study is necessary to review the current approach. Method: We assessed the visual fatigue, subjective work load and task performance according to the three illumination situations(Normal Illumination, Emergency Illumination, and Drastic Change of Illumination). Result: Research finding shows that there are not significant differences in task performance between normal illumination (1,000lx level) and emergency illumination (100lx level), only if beyond the dark adaptation limit. However, subjective work load on mental demand and visual fatigue show a potential challenge to visual performance in drastic change of illumination. Conclusion/Application: Several trials can complement this challenge in NPPs by applying 3-way communication, enhancing readability of procedures, and managing the visual factors affecting the operators' performance through a Visual Environment Management Program including visual health aspects, etc.

Purpose: To determine effects of job-seeking stress on perimenstrual symptoms of female college students with health and non-health related majors and mediating effects of stress coping styles. Methods: Data were collected from 189 female college students who were juniors or seniors. This study was conducted using questionnaires on job-seeking stress, perimenstrual symptoms, and stress coping styles. Data analysis included descriptive statistics, Pearson correlation analysis, and multiple regression analysis using SPSS, version 23.0. Mediation analysis was performed according to the Baron and Kenny method and Sobel test. Results: Job-seeking stress was significantly and positively correlated with perimenstrual symptoms in non-health college students. Passive stress coping styles demonstrated a complete mediating effect on the relationship between job-seeking stress and perimenstrual symptoms of those with non-health related majors (${\beta}=0.31$, p=.002). Such effect was significant (Sobel test; Z=2.06, p=.039). Conclusion: Effects of job-seeking stress on perimenstrual symptoms were mediated by passive stress coping styles of non-health related major students. Based on findings of this study, effective stress cope strategies should be developed considering characteristics of majors to manage perimenstrual symptoms of female college students with high job-seeking stress.

The aim of this study was to achieve an understanding of the experiences of divided families in South Korea. The study adopted a qualitative method based on the interpretive science paradigm The participants were 14 elderly people who came from North Korea around 1950 and identified as belonging to the first generation of divided families. In-depth individual interviews were carried out, focusing on what divided families experienced after leaving their hometown, how these experiences affected their meaning-making about their homecoming, and how the divided community has changed. The result of theme analysis indicated that the first generation of divided families identified themselves as "people who lost their hometown." their hometown implied multiple losses, including their family members, socioeconomic status, and psychological support systems. The participants explained the process of their settlement and adaptation to South Korea based on the cohesion of the divided family community. However, they anticipated that the divided family community would fade away because of the aging of the first generation, the indifference of the second generation, and the frustration that existed about the reunion of the divided family members. The participants showed a realistic view on returning to their hometown after the reunification of North Korea and South Korea.

Purpose: This follow up study was performed to survey the problem in performing ADLs at home after surgery. Method: Twenty elderly patients were assessed 3 times; from the time of hospitalization for surgery until 3 weeks after discharge. Measuring tools are numeric rating scales (NRS) for pain and 3 questionnaires developed by the authors to measure difficulties in ambulation, performing indoor ADLs, and emotional status. Pearson correlation, variance analysis and descriptive statistics were used to analyze the data. Result: The level of pain significantly decreased after surgery, but the difference between pain at the time of discharge and that of 3 weeks after discharge were not significant. Pain showed a positive relationship with emotional difficulties. Elderly with a higher education, family caregiver, and regular exercise showed a lower level of emotional difficulties. Conclusion: Comprehensive approaches for chronic pain including physical, psychological, and social aspects should be considered when caring for the elderly with spinal surgery. In addition, home care nursing interventions should include an exercise program to promote adaptation and rehabilitation after discharge.

Purpose: The purpose of this study was to develop a scale to evaluate posttraumatic growth in patients with cancer and to examine the validity and reliability of the scale. Methods: A literature review, semi-structured patient interviews and an expert panel consultation produced a 27 preliminary item questionnaire. Participants were 150 cancer patients recruited to test the reliability and validity of the preliminary scale. Data were analyzed using item analysis, exploratory factor analysis, convergent validity and internal consistency. Results: Item reduction and exploratory factor analysis led to 23 items, grouped into five subscales which were labelled new possibilities (6 items), coping skills (5 items), preciousness of life (5 items), relating to others (4 items), and personal strength (3 items). Convergent validity was evaluated by total correlation with the Functional Assessment of Cancer Therapy-General (r=.45, p<.001). The final scale demonstrated satisfactory internal consistency (Cronbach's ${\alpha}$ =.94). Conclusion: Findings from this study indicate that the Cancer-Specific Posttraumatic Growth Inventory has validity and reliability and is considered to be appropriate for assessing posttraumatic growth in patients with cancer.

Purpose: Optimism is an important psychological variable that functions positively in stress adaptation process. The purpose of this study was to identify either a mediating or moderating effect of optimism in the relationship between stress and well-being among mothers of children with diabetes mellitus. Methods: A sample of 109 mothers of children with diabetes mellitus was recruited in a tertiary hospital in B city and they completed self-reported questionnaires. Multiple regression analysis models were used to test the mediating and moderating effects of optimism in the relationship between stress and well-being. Results: The results of the multiple and hierarchical regression analysis showed that the role of optimism was examined a partial mediator of the relation between stress and well-being, not a moderator. Increased stress was associated with decreasing optimism and well-being, and increased optimism predicted increased well-being among mothers of children with diabetes mellitus. Conclusion: Optimism is more likely to play a role as mediator, rather than as a moderator. This finding suggests the importance of optimism in improving the well-being of mothers of children with diabetes mellitus.

Purpose: This study aimed to investigate the correlation between death anxiety, terminal care stress, and job satisfaction of new nurses, as well as to identify factors affecting job satisfaction using descriptive correlations. Methods: This study included 143 new nurses who had 3 to 12 months of experience in terminal care. Data were collected from January to February 2018, and were analyzed using descriptive statistics, t-test, ANOVA, Scheffe? test, Pearson's correlation coefficient, and hierarchical regression analysis. Results: There was a negative correlation between job satisfaction and terminal care stress (r=-.170, p=.043), while death anxiety and terminal care stress were positively correlated (r=.284, p=.001). The following findings demonstrated a significant effect on job satisfaction: lesser the clinical career experience, the lower the job load causing death anxiety and terminal care stress, and the higher the job satisfaction. Furthermore, the explanatory power of these factors was 15.1%. Conclusion: To assist new nurses within three months of joining in clinical adaptation, it is necessary to provide them with appropriate knowledge regarding terminal care through training, and with counseling opportunities for the psychological burdens they experience while caring for dying patients.
