Purpose: The purpose of this study was to assess the psychosocial work environment of hospital nurses to identify influences of psychosocial work environment on stress, depression, sleep disorder, and burnout. Methods: A total of 219 nurses working in one hospital were surveyed by using the Korean version of the Copenhagen Psychosocial Questionnaire (COPSOQ-K) mental health and psychosocial work environment. The impact of the psychosocial work environment on mental health was analyzed using multiple regression. Results: Mental health variables are correlated with each other. The psychosocial work environment variables and mental health variables are mostly correlated. To assess the psychosocial work environment that affects mental health the most, multiple regression was used. Work-family conflict was the most powerful explanation of all the mental health variables. Work pace, social community at work, mutual trust among employees, predictability, and influence were found to be affecting some mental health variables. Conclusion: To improve the mental health of nurses, it is necessary to consider work pace, social community at work, mutual trust among employees, predictability, influence focus on work-family conflict.

Purpose: To assess levels of mental health among community health practitioners during the COVID-19 outbreak in Korea and associations between practitioner mental health and personal and psychosocial factors. Methods: Data were collected from a convenient sample of 275 community health practitioners using an online questionnaire, which included items on mental health (K-WEMWBS), psychosocial factors (COVID-19 sensitivity, COVID-19 self-confidence, social support, perceived stress), and personal characteristics. Collected data were analyzed using the t-test, one-way ANOVA, Scheffe's test, Pearson's correlation coefficients, and multiple linear regression in SPSS 25.0. Results: Mean mental health score was 51.27±8.47. Multiple linear regression revealed that time spent as a community health practitioner, COVID-19 self-confidence, social support, and perceived stress were significantly associated with mental health. Conclusion: The findings of this study suggest that comprehensive intervention with emphases on improving COVID-19 self-confidence, social support, and reducing stress is required to improve community health practitioner mental health. The results also indicate a need for educational programs aimed at improving the mental health of young community health practitioners.

Purpose: This study investigated sleep satisfaction and influencing factors in Korean adolescents with atopic dermatitis. Methods: Data were obtained from 4,570 subjects who completed the 2017 13th Korea Youth Risk Behavior Web-based Survey. For data analysis, descriptive statistics and multiple-sample logistic regression were used. Results: The results of this study were as follows. Gender, academic achievement, economic status, perceived stress, happiness, health status, and depression in the subjects showed a significant difference in terms of sleep satisfaction in atopic adolescents. Multiple-sample logistic regression analysis showed that male adolescents (odds ratio (OR)=0.48), academic achievement (low OR=0.67, middle OR=0.78), economic status (low OR=0.50, middle OR=0.64), lack of depression (OR=0.63), perceived stress (very OR=4.65, a little OR=2.25), perceived happiness (unhappy OR=1.99, moderate OR=1.22), perceived health status (unhealthy OR=2.17, ordinary OR=1.35), alcohol nondrinking (OR=0.75), and nonsmoking (OR=0.73) were not associated with sleep satisfaction. Conclusion: It is necessary to develop interventions that can relieve stress management and depression and develop positive emotions in atopic adolescents. In addition, there is a need to improve the environment to avoid health risks such as alcohol consumption and smoking and to minimize the effects of passive smoking.

Purpose: This study measured the mental health levels of 119 paramedics, and identified the association of mental health levels with safety environments, personal protective equipment, and coronavirus risk awareness. Methods: A total of 119 out of 428 from Daegu and Gyeongbuk took part in this study. The statistical analysis methods were the t-test, ANOVA, Pearson's correlation analysis and multiple regression analysis. Results: In a multiple regression analysis, females (β=-.137, p=<.001) showed a higher relevance to negative mental health than males. The moderate satisfied (β=-.088, p=.014) and dissatisfied (β=-.147, p=.006) showed a higher relevance to negative mental health than higher satisfied. Moderate stress perception (β=-.199, p=<.001) and higher stress perception (β=-.414, p=<.001) showed a higher relevance to negative mental health than lower stress perception. Corona-virus risk awareness (β=-.050, p=.045) was related to negative mental health and safety environment (β=.136, p=<.001). Personal protective equipment (β=.147, p=<.001) were related to positive mental health. Conclusion: Conclusively, it is necessary to develop and implement high-quality intervention programs using significantly influencing variables to impact the mental health of 119 paramedics.

One of the recent proposals with nuclear magnetic resonance (NMR) is a multi-bore NMR which consists of array of magnets which could present possibilities to quickly cope with pandemic virus by multiple inspection of virus samples. Low temperature superconductor (LTS) can be a candidate for mass production of the magnet due to its low price in fabrication as well as operation by applying the helium zero boil-off technology. However, training feature of LTS magnet still hinders the low cost operation due to multiple boil-offs during premature quenches. Thus in this paper, LTS magnet with low mechanical stress is designed targeting the "training-free" LTS magnet for mass production of magnet array for multi-bore NMR. A thorough process of an LTS magnet design is conducted, including the analyses as the followings: electromagnetics, mechanical stress, cryogenics, stability, and protection. The magnet specification was set to 4.7 T in a winding bore of 85 mm, corresponding to the MR frequency of 200 MHz. The stress level is tolerable with respect to the wire yield strength and epoxy crack where mechanical disturbance is less than the minimum quench energy.
