Purpose: This study aimed to develop and test a structural equation model of health-related quality of life among older women following bilateral total knee replacement based on a literature review and Wilson and Cleary's model of health-related quality of life. Methods: One hundred ninety three women who were diagnosed with osteoarthritis, were older than 65 years, and were between 13 weeks and 12 months of having a bilateral total knee replacement were recruited from an outpatient clinic. Data were collected from July 2017 to April 2018 using a structured questionnaire and medical records. Data were analyzed using SPSS/WIN 22.0, AMOS 22.0, and Smart PLS 3.2.4. Results: The fitness of the hypothetical model was good, with coefficients of determination (R²) ranging between .28 and .75 and predictive relevance (Q²) between .26 and .73. The standardized root mean square residual of the model fit indices for the hypothetical model was .04; which explained 64.2% of physical and 62.5% of mental health-related quality of life. Self-efficacy, symptom status, functional status, and general health perceptions had a significant direct effect on physical health-related quality of life, while social support, symptom status, and general health perceptions had a significant direct effect on participants' mental-health-related quality of life. Conclusion: To improve the physical and mental quality of life of older women who receive bilateral knee replacement, nursing-based intervention strategies that reduce symptoms, improve functional status, and increase health perceptions, self-efficacy, and social support are needed. The most important factor is the symptom status.

Purpose: The purpose of this study is to develop a model for predicting mental health risk among adolescents based on health behavior information by employing a hybrid machine learning method. Methods: The study analyzed data of 51,850 domestic middle and high school students from 2022 Youth Health Behavior Survey conducted by the Korea Disease Control and Prevention Agency. Firstly, mental health risk levels (stress perception, suicidal thoughts, suicide attempts, suicide plans, experiences of sadness and despair, loneliness, and generalized anxiety disorder) were classified using the k-mean unsupervised learning technique. Secondly, demographic factors (family economic status, gender, age), academic performance, physical health (body mass index, moderate-intensity exercise, subjective health perception, oral health perception), daily life habits (sleep time, wake-up time, smartphone use time, difficulty recovering from fatigue), eating habits (consumption of high-caffeine drinks, sweet drinks, late-night snacks), violence victimization, and deviance (drinking, smoking experience) data were input to develop a random forest model predicting mental health risk, using logistic and XGBoosting. The model and its prediction performance were compared. Results: First, the subjects were classified into two mental health groups using k-mean unsupervised learning, with the high mental health risk group constituting 26.45% of the total sample (13,712 adolescents). This mental health risk group included most of the adolescents who had made suicide plans (95.1%) or attempted suicide (96.7%). Second, the predictive performance of the random forest model for classifying mental health risk groups significantly outperformed that of the reference model (AUC=.94). Predictors of high importance were 'difficulty recovering from daytime fatigue' and 'subjective health perception'. Conclusion: Based on an understanding of adolescent health behavior information, it is possible to predict the mental health risk levels of adolescents and make interventions in advance.

Objectives : This study investigated the prevalence of unmet health care needs among Korean adults and related factors. Methods : The study participants were adults over the age of 20 mental health experience from the Korea Health Panel in 2012(n=4,730). Statistical analysis methods used in this study were the ${\chi}^2$-test, Logistic Regression Analysis and other basic statistics such frequency-and percentage using SPSS version 22.0. Results : (1)Significant variables of stress: Factors were age, economic activity, subjective health status, and activity limitation. (2)Significant variables of depression: Factors were age, income class(low) and activity limitation. (3)Significant variables of suicidal impulse: Factors were age, chronic diseases, income class, and activity limitation. Conclusions : Stress, depression, and suicidal impulse can be unmet medical factors; therefore improvement measures and mental health counseling programs in response to suicide impulses, should be developed. Thus there is a need for a health sciences approach.

Purpose: This study was to examine the effect of postpartum exercise on mental health. Mental health comprises a 9 symptom dimension of Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic anxiety, Paranoid Ideation, and Psychoticism. Method: A non-equivalent pre-test, post-test control group study was conducted. Fifty-two puerperal women who were admitted to a postpartum ward of a mother-baby clinic in Pusan were recruited; 26 women were assigned to the experimental group and 26 women to the control group. Postpartum exercise was applied to the experimental group from postpartum day 3 for a period of 8 weeks while no exercise program was applied to the control group. Mental health with SCL-90-R was measured before and after exercise. Data was analyzed using mean, $x^2$-test, t-test, and ANOVA by SPSS 10.0. Result: The mental health status in the exercise group did not show a statistically significant decrease when compared to that of the control group. Conclusion: There is no effect of postpartum exercise on women's mental health during the first 8 weeks of the postpartum period. Further studies are needed for randomized clinical trials with a larger sample size.

Purpose: The purpose of this study was to determine correlates of depression and perceived health status in patients with atrial fibrillation. Methods: The study utilized a descriptive correlational survey design. A convenience sample of 115 subjects were recruited from 3 tertiary medical centers. The data were analyzed by descriptive statistics, hierarchical multiple regression. Results: 1) Study subjects perceived the low frequency of symptoms, relatively high social support, low depression, moderately low physical health, and mental health. 2) The 38% of variance in depression was significantly explained by symptom(${\beta}$ = .49), social support(${\beta}$ = -.21), and education(${\beta}$ = -.17). 3) The 40% of variance in physical health was significantly explained by symptom(${\beta}$ = -.55), social support(${\beta}$ = .16), and education(${\beta}$ = .20). 4) the 12% of variance in mental health was significantly explained by symptom(${\beta}$ = -.26), and social support(${\beta}$ = .24). Conclusion: Most health care providers assume atrial fibrillation patients have very few symptoms. However, symptom related to atrial fibrillation was found to be the most important factors in explaining depression and perceived health status. Additionally, higher social support had great influences on the lower depression and higher perceived health status. Based on the findings of this study, directions for nursing practice and further nursing research for patients with atrial fibrillation are suggested.

Objective : Hospital workers' mental health has deteriorated because of the ongoing COVID-19 pandemic. The purpose of this study was to investigate the impact of the prolonged COVID-19 pandemic on the mental health of hospital workers and its determinants. Methods : Two surveys were conducted among employees working in a hospital that received COVID-19 patients from the early phase of the pandemic in South Korea. Data on demographics, perceived threat, workplace evaluation, resilience, and mental health status were collected using the Korean General Health Questionnaire-20 in the initial phase (February 2020) and during the third wave of COVID-19 (December 2020) for 467 and 545 workers, respectively. The mental health of hospital workers in the two phases was compared, and the risk and protective factors during the third wave were investigated. Results : The proportion of patients in the psychiatric high-risk group increased from 2.8% in the initial phase to 11.4% during the third wave. The perceived threat, workplace evaluation, and resilience of respondents deteriorated. Risk factors for mental health during the third wave included the perceived threat items of job stress, loss of control, and considering resignation. Protective factors included presence of children, workplace satisfaction, and hardiness in resilience. Conclusion : Hospital workers' mental health deteriorated as the pandemic progressed. General stress and tension such as job stress, loss of control, considering resignation rather than COVID-19-specific stress had negative effects on mental health of hospital workers. Therefore, care for work stress itself can be helpful to maintain the mental health of hospital workers. Also, governance to improve workplace satisfaction or hardiness in resilience can be a potential protective factor for hospital workers' mental health during the prolonged pandemic.

Purpose: The purpose of this study was to examine the relationship between test anxiety, self-esteem and mental health. Method: Data were collected by structured questionnaires from 306 nursing students in a dormitory for the national examination for registered nurses. Collected data were analyzed by t-test, ANOVA, scheffe's test and Pearson's correlation coefficient and hierarchial multiple regression through the SPSS WIN program. Result: The results of the analysis showed that the mean for test anxiety was $79.70{\pm}18.74$ points, the degree of self-esteem was $28.26{\pm}5.02$, and mental health was $24.31{\pm}13.07$. In the correlation analysis, mental health positively correlated with test anxiety (r=.559, p=.000) and negatively correlated with self-esteem (r=-.141, p=.013). Test anxiety and subjective health status explained 36.4% of mental health. Conclusion: This finding of this study recommends that test anxiety control and self-esteem enhancement programs should be development for mental health promotion in nursing students taking the national examination for registered nurses.

Objectives: The purpose of this study is to analyze factors associated with depression among workers in South Korea by socio-economic factors, health behaviors, and working conditions. Methods: Study subjects include 4,251 adults (19 and older) who are currently working using the data from 2009 National Health and Nutrition Survey. Data were analyzed using frequency test, $X^2$ test, and multiple logistic regression. Results: Multiple logistic regression analysis showed that gender (OR=1.91, p<.001), age (OR=1.53, p=.030), marital status (31-39: OR=1.88, p=.029) were significantly related to depressing among socio-economic factors. Next, among health behaviors factors, perceived health status (Poor: OR=1.76, p=.049; Very poor: OR=3.46, p=.002) was statistically significant. Among characteristics of work environment, trust and respect (OR=1.34, p=.049) and working with hidden emotion (OR=1.88, p<.001) were significantly related to depression. Conclusions: In order to manage and reduce depression among workers, it is important to develop appropriate mental health promotion programs both in work places and in regulations.

Objectives : The aim of this study was to examine attitudes of middle-school students toward happiness, suicide, and factors associated with suicide. Methods : A self-administered questionnaire was used in a cluster sample of 1,319 middle-school students (male 793, female 526). Data were obtained on a wide range of constructs regarding their attitude towards happiness, suicidal ideation and attempts, and factors associated with suicide. Results : Middle-school students choose 'love within family' as most important factor for their happiness. Subjective mental health status was mostly associated with happiness. Subjects in lower socioeconomic status tended to respond their mental health status was not good and have more suicidal idea. 48.7% of subjects had permissive attitudes toward suicide, especially, girls. However, 65.0% responded that suicide was preventable problem. Compared to older people, middle-school students perceived that environmental factors were more important than innate and personal factors for suicide. Conclusion : Results of the study indicate that middle-school students have permissive attitudes toward suicide, but positive attitudes for the prevention of suicide. This suggest that education in these age group could be effective for the prevention of suicide. Also, approaches to suicide prevention programs should be developed based on the family intervention. Especially, we should care about girls and adolescents in lower socioeconomic status.
