Objectives : The purpose of this study was to investigate the correlation of stress and meridian muscle electrography in Korean adult males. Methods : Sixty-nine volunteers suffering from stress participated in this study. Physical examination, stress survey and meridian muscle electrography were performed. Each variable was compared with each other by correlation analysis. Results : Correlation between stress response inventory and fatigue of trapezius muscle right upper portion was statistically significant. In relationship between sub scales of stress response inventory and meridian muscle electrography, fatigue of trapezius muscle right upper portion was statistically significant with tension, depression, and frustration. Contraction power of left sternocleidomastoid muscle was significant with somatization and others were not significant. Conclusions : In Korean adult males, trapezius muscle shows more fatigue under more stress. This suggests that stress influences muscle fatigue. Although meridian muscle electrography is not a typical method for the evaluation of pain nor stress, this is referential method to clinical evaluation of painful shoulder caused stress.

Objectives: The purpose of this study was to examine the mediating effect of self-esteem or social support on job-related stress and depression among emergency medical technicians (EMTs). Methods: Data were collected from EMTs at emergency medical institutions and fire stations (n=257). The data were analyzed using descriptive statistics, t-test, Pearson correlation coefficient, and stepwise multiple regression with SPSS WIN 21.0. Results: Self-esteem and social support of EMTs were found to be at moderate levels (Self-esteem: M=3.04, SD=0.43; Social support: M=3.65, SD=0.43) Job-related stress was positively correlated with depression: the higher the job-related stress score, the higher the depression score. Moreover, self-esteem score or social support score was negatively associated with job-related stress and depression: the higher the self-esteem score or the higher the social support score, the lower the job related stress score and the depression score. Conclusions: Future research should address how social support and networks interact and together affect self-esteem for job-related stress and depression.

Purpose: This descriptive study investigated the relationship between death awareness and life ethics awareness, according to life stress, among students in the department of paramedics. Methods: General characteristics were identified using means and frequency, and the differences between the two military models were analyzed using the χ²-test and t-test by dividing them into lower and higher groups based on the mean life stress score (99.76 points). Results: Those with high life stress had higher death awareness than those with low life stress at 114.11 points. In contrast, those with low life ethics experienced more severe life stress with a score of 145.61 points (t=-2.609, p=.010)(t=-2.953, p=.003). The death recognition attitude and bioethics according to the degree of living stress-showed a significant correlation between the low and high groups (r=.188, p=.043) (r=.201, p=.042). Conclusion: Paramedic students require education on how to cope with life stress. However, access to education is limited to people living in modern times. As a potential solution to this problem, observing videos on the Internet is recommended. Moreover, we suggest accessing Internet and smart phone applications for advertising/educational purposes.

This study aimed to analyze trends in research on depression among medical students in Korea and to conduct a meta-analysis to determine the average correlation coefficients between depression and related variables. In total, 38 quantitative studies (four theses and 34 journal articles) published between January 1995 and February 2023 were analyzed according to publication year, subjects, analysis methods, and measurement tools. Among them, 15 studies that provided numerical information on the relationships between depression and variables such as self-esteem, social support, grade point average (GPA), stress, and academic stress were selected for meta-analysis. The main findings of this study were as follows. First, quantitative research on depression among medical students began in earnest in 2009, and cross-sectional studies targeting first-year and second-year medical students were the most prevalent. Furthermore, the most commonly used analysis method was difference testing, and the Beck Depression Inventory was the most frequently used measurement tool. Second, the mean correlation coefficients between depression and stress, self-esteem, social support, academic stress, and GPA were 0.534, 0.532, 0.465, 0.390, and 0.102, respectively. The results for self-esteem, stress, and academic stress showed substantial heterogeneity, while those for social support and GPA showed little heterogeneity. These findings suggest that educational interventions, such as social support improvement programs, are necessary to prevent depression among medical students.

Purpose: The purpose was to examine the level of perceived stress, lifestyle, and health status indicators and identify the relationships among them in medical center employees. Method: This study utilized data from Cohen's Perceived Stress Scale, health survey developed by National Health Insurance Corporation, and laboratory tests (such as liver enzyme or lipid profile) on 873 medical center employees. The data were analyzed using the SPSS 12.0 program through descriptive statistics, $x^2-test$, independent t-test, ANOVA and ANCOVA. Results: Perceived stress was relatively high, but lifestyle and health status indicators were good. Age, gender, and job were significantly related to perceived stress, life style, and health status indicators: younger employees, men, nurses reported higher stress; older employees, men and medical technicians reported worse life style; older employees, men and doctors showed more abnormal health status indicators. There was a significant relationship between perceived stress and life style: the higher the level of stress was, the more drinking or the more smoking they had. However, there was no clear relationship between perceived stress and health status indicators. Conclusion: Although the subjects' lifestyle and health status indicators were relatively good, their perceived stress was seriously high. Therefore, programs for reducing stress are necessary for medical center employees.

Background: Job stress and job satisfaction are important factors affecting workforce productivity. This study was carried out to investigate the job stress, job satisfaction, and workforce productivity levels, to examine the effects of job stress and job satisfaction on workforce productivity, and to identify factors associated with productivity decrement among employees of an Iranian petrochemical industry. Methods: In this study, 125 randomly selected employees of an Iranian petrochemical company participated. The data were collected using the demographic questionnaire, Osipow occupational stress questionnaire to investigate the level of job stress, Job Descriptive Index to examine job satisfaction, and Hersey and Goldsmith questionnaire to investigate productivity in the study population. Results: The levels of employees' perceived job stress and job satisfaction were moderate-high and moderate, respectively. Also, their productivity was evaluated as moderate. Although the relationship between job stress and productivity indices was not statistically significant, the positive correlation between job satisfaction and productivity indices was statistically significant. The regression modeling demonstrated that productivity was significantly associated with shift schedule, the second and the third dimensions of job stress (role insufficiency and role ambiguity), and the second dimension of job satisfaction (supervision). Conclusion: Corrective measures are necessary to improve the shift work system. "Role insufficiency" and "role ambiguity" should be improved and supervisor support must be increased to reduce job stress and increase job satisfaction and productivity.

Background: Obesity is a risk factor for aging and many diseases, and the disorder of lipid metabolism makes it prominent. This study aims to investigate the effect of ginsenoside Rg1 on aging, lipid metabolism and stress resistance Methods: Rg1 was administered to Caenorhabditis elegans (C. elegans) cultured in NGM or GNGM. The lifespan, locomotory activity, lipid accumulation, cold and heat stress resistance and related mRNA expression of the worms were examined. Gene knockout mutants were used to clarify the effect on lipid metabolism of Rg1. GFP-binding mutants were used to observe the changes in protein expression Results: We reported that Rg1 reduced lipid accumulation and improved stress resistance in C. elegans. Rg1 significantly reduced the expression of fatty acid synthesis-related genes and lipid metabolism-related genes in C. elegans. However, Rg1 did not affect the fat storage in fat-5/fat-6 double mutant or nhr-49 mutant. Combined with network pharmacology, we clarified the possible pathways and targets of Rg1 in lipid metabolism. In addition, Rg1-treated C. elegans showed a higher expression of anti-oxidative genes and heat shock proteins, which might contribute to stress resistance Conclusion: Rg1 reduced fat accumulation by regulating lipid metabolism via nhr-49 and enhanced stress resistance by its antioxidant effect in C. elegans.
