This study utilized data from 1,068 women aged 40-59, drawn from the 8th Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2020, to investigate factors impacting subjective health perception and health-related quality of life. Methodologically, STATA 15.0 was employed for complex sample mean and standard deviation calculations, complex sample weighted percentages, complex sample t-tests, and multiple regression analyses. Common factors influencing both subjective health and health-related quality of life included education level, household size, depression, and stress. Age, binge drinking, and physical activity were identified as factors influencing subjective health perception. Insurance type, employment status, and sleep disorders emerged as factors impacting health-related quality of life. Recognizing middle age as a crucial transitional phase into old age, the development of health policy programs aimed at enhancing subjective health and health-related quality of life during this period is deemed essential.
Workers in the agricultural industry have been exposed to many work-related musculoskeletal disorders. So, our objectives in this study were to measure and analyze worker's physiological bio-information to reduce musculoskeletal disorders in relation to agricultural works. We investigated worker's bio-information of physiological signals during the repeated lifting work such as body temperature, heart rate, blood pressure, physical activity, and heart rate variability. Moreover, we analyzed the workloads of lumbar spine during the repeated lifting work using the 3-axis acceleration and angular velocity sensors. The changes of body temperature was not significant, but the mean heart rate increased from 90/min to 116/min significantly during 30 min of repeated lifting work (p<0.05). The average worker's physical activity(energy consumption rate) was 206 kcal/70kg/h during the repeated lifting work. The workers' acute stress index was more than 80, which indicated a stressful work. Also, the maximum shear force on the disk (L5/S1) of a worker's lumbar spine in static state was 500N, and the maximum inertia moment was 139 $N{\cdot}m$ in dynamic state.
Purpose: The aim of this study was to investigate the association between job stress and metabolic syndrome among male workers. Methods: A total of 396 male workers employed in an electronic company, located in 'P' city, Gyeonggi Province, who had taken medical examination at the 'D' hospital, volunteered in this study. All the data used in this study were obtained from 'D' hospital after getting consent and permission from the workers. General and occupational characteristics, medical history, and health-related behaviors of the subjects were obtained by self-administered questionnaire. Results: The highest occupational stress by sub-sector was reported in the order of insufficient job control, organizational system, lack of reward, job demand, job insecurity, physical environment, job culture, and relationship conflict. The prevalence rate of metabolic syndrome of the participants was 19.9%. The results of the multiple logistic regression analysis on metabolic syndrome of the subjects indicated that the syndrome was significantly higher among those with family history, smoking habit and ex-smoking, working duration of 3 years and over, and with higher total score of occupational stress. It was significantly more prevalent, when the degree of stress was high in the sub-sectors of occupational stress; job autonomy, job insecurity, lack of reward, and job culture. Conclusion: In conclusion, it is necessary to implement a plan to efficiently manage the job stress of these male workers, as the probability of metabolic syndrome increased with the increase of occupational stress. Furthermore, considering the highest occupational stress was found to be job autonomy among its sub-sectors, it is necessary to prepare various measures to enhance the autonomy of such employees.
The purpose of this study was to investigate the relationship between job stress and coping style in college students. Participants were 314 students in a college. Data were collected using a self administered questionnaire. The survey was conducted from May 02, 2018 to May 28, 2018. There were statistically significant correlations between personality stress, family environmental stress, academic stress, school environment stress and emotion - centered coping style among sub - variables of job stress, Job anxiety stress was significantly correlated with social support seeking and emotion - centered coping style. Since college students' emotional stress coping style is related to depressive emotional and physical health problems, it is necessary to provide a psychological treatment program for early detection and coping with psychological support services, and a mixed service such as education, lecture, and camp. In addition, it is thought that strategic action skill training (plan, method, and technology) is needed to change from emotion - centered coping style to problem - solving style.
BACKGROUND/OBJECTIVES: Emotional eating is one of the eating behaviors in which negative emotions affect eating. During the luteal phase, premenstrual syndrome (PMS) and its associated psychological and physical symptoms can appear in some women, and a few of them suffer from premenstrual dysphoric disorder (PMDD), a severe form of PMS. Some women diagnosed with PMS/PMDD experience emotional eating during the luteal phase, which may be a coping mechanism for psychological stress. This study aimed to investigate how PMS/PMDD and negatively perceived stress are related to emotional eating. SUBJECTS/METHODS: A total of 409 women aged 20 to 39 yrs with a body mass index (BMI) ranging from 18.5 to 29.9 kg/m2 participated in this study. Participants who responded to all the questions of the Shortened Premenstrual Assessment Form, Negative Perceived Stress Scale, and Emotional Eater Questionnaire were divided into a PMDD and a non-PMDD group according to the cut-off value for PMDD diagnosis. Independent t-tests and mediation analyses were performed to compare the 2 groups. RESULTS: No significant differences between the 2 groups were found in terms of BMI; however, the average values for emotional eating, PMS, and negative perceived stress of the PMDD group were significantly higher than those of the non-PMDD group. Only negative perceived stress had a significant effect on emotional eating in the non-PMDD group. In the PMDD group, PMS was statistically significant for both negative perceived stress and emotional eating mediated by negative perceived stress. Consequently, it appeared to have a partial or complete mediation depending on the independent variable for the PMDD group. CONCLUSIONS: This study highlights the importance of managing negative perceived stress to control emotional eating in PMS/PMDD for improved women's health.

Purpose: The purpose of this study was to examine factors related to burnout of nurses at hemato-oncology wards. Methods: The participants were 134 nurses working at hematology-oncology wards in three tertiary general hospitals in Seoul and Gyeonggi Province. Data were collected using a structured questionnaire that consisted of personal characteristics, occupational stress, satisfaction and burnout. Using a SPSS/WIN 12.0 program, descriptive statistics, t-test, ANOVA, and stepwise multiple regression procedures were employed. Results: The mean score of burnout reported by the participants was $3.15{\pm}0.50$ (range 1~5), showing the highest scores in the area of physical burnout ($3.53{\pm}0.57$). The satisfaction with nursing profession was found to be the most impact on the burnout of the hematology-oncology ward nurses (${\beta}$=-.533), followed by occupational stress (${\beta}$=.351) and years of clinical experiences (${\beta}$=-.154).

Unlike artificially created homogeneous materials, the process of calculating the elastic modulus of natural soil involves the possibility of errors. Because the stress-strain behavior of soil is nonlinear, the secant modulus of elasticity is often used based on 1/2 of the stress at failure. Since soil has the property of changing its elastic modulus depending on the confining pressure, numerical analysis models that analyze its behavior inevitably include complex elements. The hyperbolic model, which relatively accurately simulates the behavior immediately after loading in soft ground, assumes that the stress-strain curve of the consolidated undrained triaxial test is hyperbolic and requires the slope of the tangent line at the starting point. However, the slope of the initial tangent in the stress-strain curve obtained from an actual triaxial test is difficult to have regularity according to changes in confining pressure. Additionally, due to the characteristics of a hyperbola, even small changes in related factors cause large changes in the hyperbola. Therefore, there is a lot of randomness in the process of calculating model parameters from the triaxial test results, which causes large differences in the results. Therefore, the method of calculating the initial elastic modulus by the consolidation test presented in this study is also used to verify the method by the triaxial test. It can be applied. However, since this study was applied to only one sample showing typical consolidation characteristics, it is necessary to check samples with various physical properties in the future.
