Purpose: The purpose of this study was to examine the relationship among subjective symptoms, depression, and stress coping behavior of university students. Method: The survey was carried out on a convenience sample of 298 university students. The questionnaire consisted of each scale for symptoms, depression, and stress coping behaviors. Data analysis procedure included the factor analysis for stress coping behaviors, and the correlation analysis describing a relationship among symptoms, depression, and stress coping behaviors. Result: There were significant correlations between depression and the three types of symptoms: general, psychological, and somatic symptom. Subjects using the negative-emotional-response coping and the self-control coping showed a more severe depression, and those using the problem-solvingㆍreappraisal coping and the positive-emotional-response coping showed a milder depression. Subjects using the negative-emotional-response coping complained of all 3 types of symptoms severely, and those using the positive-emotional-response coping complained of general symptoms mildly. Of five stress coping methods, the negative-emotional-response and the positive-emotional-response coping methods were related to both symptoms and depression significantly. Conclusion: This study suggests that the emotional-oriented coping method has more important role for university student’s depression and their subjective symptoms than the problem-oriented coping or social supports seeking coping. Further study needs to be conducted to help students effective coping mechanism for good mental health. Also it is necessary for university students to recognize that their symptoms are associated with depression.

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.

Background: Posttraumatic stress symptoms (PTSS) in patients with psychological trauma lead to poor health-related quality of life. Understanding of the relationships among PTSS, anxiety, depression, and illness intrusiveness will guide the development of efficient approaches to enhance subjective well-being in patients with psychological trauma. This study investigated whether anxiety and depression mediate the relationship between PTSS and illness intrusiveness in the hope of providing more comprehensive and effective trauma treatment. Methods: Psychiatric outpatients who visited the trauma clinic of a university hospital (n = 260) participated in this study. Assessments were conducted for PTSS, anxiety, depression, and illness intrusiveness. Structural equation modeling and path analysis were performed to analyze the mediating effects of anxiety and depression on the relationship between PTSS and illness intrusiveness. Results: PTSS had both direct and indirect exacerbating effects on illness intrusiveness. Anxiety exhibited the largest direct exacerbating effect on illness intrusiveness. The indirect effects of PTSS on illness intrusiveness through anxiety alone and through a depression-to-anxiety pathway were significant, but the indirect effect through depression alone was not. Conclusion: The findings demonstrate that anxiety, both independently and as part of an interrelated pathway with depression, partially mediates the relationship between PTSS and illness intrusiveness. Appropriate interventions and a comprehensive approach to alleviate anxiety and depression could mitigate the negative effects of PTSS on illness intrusiveness in patients with psychological trauma.

Purpose: This study aimed to investigate the changes in health behavior, mental health, and nutritional status of Korean adolescents before and after the coronavirus disease 2019 (COVID-19) pandemic outbreak. Methods: A total of 800 adolescents (12~18 years old) who participated in the 2019-2020 Korea National Health and Nutrition Examination Survey (KNHANES) were included as study subjects and divided into four groups (204 middle school boys, 172 middle school girls, 219 high school boys, and 205 high school girls). The 2019 and 2020 KNHANES data were classified into data collected before and after the COVID-19 outbreak, respectively. Results: After the COVID-19 pandemic outbreak, middle school boys showed an increased tendency toward becoming overweight and obese, with significantly increased levels of diastolic blood pressure and insulin. While there was no major change in the subjective health status among adolescents, the high school boys showed a significantly decreased physical activity after COVID-19 outbreak. Moreover, the proportion of middle school students feeling a little stressed significantly increased after the COVID-19 outbreak. The rate of skipping breakfast significantly increased in middle school girls, but the rate of having lunch with companions significantly increased among all adolescents after the COVID-19 outbreak. However, the intake of milk, vegetables, fruits, seaweeds, and pulses significantly decreased, although the intake of sugars, beverages, and seasonings significantly decreased as well, during this period. These changes may lead to an increased proportion of adolescents with insufficient intake of nutrients, including potassium, vitamin C, and riboflavin. Conclusion: These results highlight the impact of COVID-19 on comprehensive changes in physical and mental health status, lifestyle behavior, and nutritional status in adolescents, suggesting the need for targeted prevention and intervention for physical and mental well-being during the pandemic.

The purpose of this study was to investigate the awareness and practice on well-being life and well-being related behaviors, and the various factors affecting well-being related behaviors such as purchasing food materials, food habits, eating out and daily routine activities. A survey was conducted by questionnaire and on a 5-point Likert scale. The subjects of this study were composed of 221 students and their 102 parents who were over 40 years residing in the Ulsan area. The results of this study are summarized as follows: Almost half of the subjects (47.4%) responded that they have good health conditions; to keep a good health condition, 41.2% of the subjects were exercising regularly and 20.4% of them kept diet control. In regard to the meaning of well-being, 66.6% of the subjects thought it is the lifestyle for physical and mental richness (children: 70.6%, parents: 57.8%). 30.3% of the subjects answered that the most important part of well-being was food related. The importance order was mental richness, food related things, physical health for children, and for the parents, it was food related things, physical health, mental richness. Most of population (45.8%) answered that they have a willingness for the pursuit of a well-being life. Among the well-being related behaviors, 69.7% of subjects have purchased items (children: 61.5%, parents: 87.3%). 37.2% of the subjects have acquired information from TV. The average well-being practice score was $61.01{\pm}10.36$. Children's scores were significantly lower than the parent's scores (p < 0.001). And the average practice score of 'purchasing food materials,' 'eating out,' 'food habits,' 'daily routine activities' were $15.3{\pm}3.3,\;15.5{\pm}3.1,\;16.8{\pm}3.3$ and $13.4{\pm}3.5$, respectively. Among five types of purchasing food materials, 'purchasing domestic agricultural food' was greatest ($3.64{\pm}0.91$) and 'purchasing of organic or low agricultural chemical food products' was lowest ($3.15{\pm}0.91$). In regard to food habits, 'eating rice and bread made of mixed grains' was greatest ($3.46{\pm}1.12$) and 'eating uncooked food or zen food' was lowest ($2.46{\pm}0.99$). The practice scores were significantly affected by gender (p < 0.05), monthly income (p < 0.01), educational level (p < 0.01), presence of disease (p < 0.05), subjective health condition (p < 0.05), well-being awareness (p < 0.001) and concern with well-being (p < 0.001). Well-being awareness scores and well-being practice scores are related positively. Therefore various programs in well-being education should be necessary in order to boost the authentic perceptions of well-being and well-being oriented behaviors in any socioeconomic situation, such as different generations; industrial companies producing well-being goods for consumer's needs and satisfaction; and government and local community create various conditions for well-being oriented behavior.

Objectives: The purpose of this study was to compare the differences in oral health-related quality of life among elderly people aged over 65 years, in terms of physical, mental and oral health status and to analyze factors affecting their oral health-related quality of life. Methods: From May 9 to June 23, 2017, we randomly visited aged-care community centers in the metropolitan area, and recruited 222 elderly, aged 65 or older. First, each participant completed a questionnaire consisting of 4 general items: 1 systematic disease, and 3 subjective oral conditions. Afterwards, the researchers interviewed the participants to assess their mental status, using MMSE-DS and recorded the responses. Finally, an oral examination was performed to determine the number of remaining teeth. The average oral health-related quality of life according to each characteristic was analyzed by t-test and ANOVA. Hierarchical multiple regression analysis and Pearson's correlation coefficient analysis were used to analyze the correlations between factors and the factors affecting oral health-related quality of life. Results: The mean oral health-related quality of life was 4.15. Participants with 20 or more remaining teeth demonstrated better oral health-related quality of life than those with 19 or less teeth. Higher oral health-related quality of life was also found among elderly without gingival bleeding, self-reported halitosis and dry mouth. In addition, positive correlation with the number of remaining teeth and negative correlation with gingival bleeding, self-reported halitosis and dry mouth, were noted. Finally, the results of the hierarchical multiple regression analysis indicated that remaining teeth, gingival bleeding, self-reported halitosis and education were influential factors in determining the oral health-related quality of life among the elderly. Conclusions: The results of this study confirmed the necessity of better policy support, and the importance of implementing delivered, elderly-centered oral health education program by professionals to prevent tooth loss and manage periodontal diseases.

Objectives: The purpose of this study was to examine the association between depression and poor oral health in Korean elderly using Korean version of the Patient Health Questionnaire-9 (PHQ-9) for assessment of depressive symptoms. Methods: This study used the data from Korean National Health and Nutrition Examination Survey (KNHANES VI-2). The study included 1,454 elderly Korean aged over 65. Variables included demographic characteristics (gender, age), socioeconomic factor (income, education), systemic diseases, oral health related factor (tooth brush, dental products), health related factor (alcohol drinking, smoking), and depression. Logistic regression analysis was used as sequential models. Effects were quantified as odds ratios (OR) and 95% confidence intervals (CI). Results: From frequency analysis, being female, primary school or less, non-alcohol drinking, poor oral health were significantly related to depression. In the multiple logistic regression model, depression was significantly associated with poor oral health (OR=1.96, CI=1.15-3.53) after adjustment for other covariates including demographic characteristics, socioeconomic factor, systemic diseases, oral health related factor, and health related factor (OR=1.91, CI=1.13-3.27). Conclusions: Depression had an influence on the poor oral health after adjustment as confounding variable in the elderly. It should be focused on the health promotion for the elderly vulnerable to depression and poor oral health. The development of the mental health and oral health should be established.
