The psychosocial stress and musculoskeletal disorders(MSDs) have been one of major health problems for hospital workers. This study tried to understand the relationship between symptoms associated with MSDs and risk factors such as working posture, job stress, psychosocial stress and fatigue. A total number of 655 hospital workers participated in this study. Specifically, REBA was applied for evaluating working posture and a checklist prepared by KOSHA(Korean Occupational Safety and Health Agency) was used for symptom survey. A questionnaire from KOSHA was also used for collecting data associated with job stress, psychosocial stress and fatigue. All these data were formulated and modeled by path analysis which was one of major statistical tools in this study. Specifically, path analysis for the data we collected came up with several major findings. The risk scores from working posture based on REBA had indirect effects via fatigue factor(MFS) as well as direct effects on symptoms. The factors associated with job stress (KOSS) and psychosocial stress(PWI-SF) had significant effects on symptoms. Specifically, indirect effect of job stress factors via fatigue factors(MFS) had bigger than that of direct effect of job stress on symptom.

Propose: To identify the effects of job stress for depression in clinical nurses. Method: The subjects were 304 clinical nurses in Busan Metropolitan City. Data was collected by questionnaire surveys using convenience sampling. The instruments used in this study were the short form of the Korean Occupational Stress Scale(KOSS-SF) and the Beck Depression Inventory-Korean Version Standard Ten(K-BDI STEN). Result: After adjusting potential confounders, we found that the group of 50~75% job stress score for interpersonal conflict was more likely to have depression than the group of less than 25%(OR=3.522, 95% CI 1.06~20.25). The group of equal or more than 75% job stress score for job insecurity was more likely to have depression than the groups of less than 25%(OR=9.413, 95% CI 4.00~71.03). The groups of equal or more than 75% and 50~ 75% job stress score for lack of reward was more likely to have depression than the group of less than 25%, respectively(OR=19.302, 95% CI 2.50~244.25; OR=38.201, 95% CI=6.25~344.45). Conclusion: To prevent depression in clinical nurses, we need to intervene job stress for insufficient job control, interpersonal conflict, job insecurity and lack of reward.

Objective : Korean employees tend to release their stress by alcohol drinking. This study aimed to investigate the association between job stress and problematic drinking in Korean employees. Methods : The study participants were 72,119 employees who attended health screenings and responded to the Alcohol Use Disorder Identification Test-Korea (AUDIT-K), Korean Occupational Stress Scale-Short Form (KOSS-SF), Center for Epidemiologic Study-Depression (CES-D), Beck Anxiety Inventory (BAI) and questionnaire on suicidal ideation and sociodemographic characteristics. We investigated the sociodemographic and clinical characteristics of the problematic drinking group ($AUIDT-K{\geq}12$) and used binary logistic regression to determine the impact of job stress on problematic drinking. Results : Age, gender, marital status, education year, sleep duration, obesity, smoking, suicidal ideation, and depression and anxiety showed significant differences between the problematic drinking group and normal group. Among the various kinds of job stresses, job insecurity and lack of reward were associated with problematic drinking. Conclusion : The result of this study suggested that certain kinds of job stress might be associated with problematic drinking in Korean employees.

A number of recent studies have shown that occupational stress is closely associated with increased fatigue and decreased job satisfaction. This study was designed to assess stress in workers in the field of EIA (environment impact assessment) from July 2009 through september 2009, and questionnaires were uesd to analyze the stress scores and identify the primary factors influencing stress in this occupation. The number of respondents was 272 working in the Capital (Seoul and Kyunggido), Chungcheongdo, Jejudo area. A structured questionnaire was used to evaluate the participants' socio-demographics, job-related factors, health-related behaviors, occupational stress, reaction factor (self-perceived fatigue, job satisfaction) and buffer factor (social support). Occupational stress and self-perceived fatigue were assessed using the Korean Occupational Stress Scale-Short Form (KOSS-SF) and the Multidimensional Fatigue Scale (MFS), respectively. The analysis revealed a strong correlation between occupational stress, job satisfaction, and social support, with occupational stress being associated with an increased risk of fatigue and decreased job satisfaction. In the multiple regression analysis(stepwise), the main factors influencing occupational stress were found to be job satisfaction, supervisor, fatigue, working time, no. of personnel, career. The results of this study suggest that occupational stress is a determinant predictor of self perceived fatigue and job satisfaction. Thus, a strong recommendation is made for a stress management program for reduction of occupational stress, and for the development of relevant experts on the health and quality of life of environment impact assessment workers.

Objectives : This study aimed to investigate the levels of emotional labor and occupational stress and their relationships in dental counselors to improve psychological health related with dental counseling. Methods : The questionnaire survey was conducted to 167 dental counselors working at dental clinics in Busan and Gyeongsangnam-do from June to August, 2012. The study used emotional labor questionnaires and Korean Occupational Job Stress Scale (Basic Version, KOSS-43) as an assessment scale. All respondents were asked to complete a self-administered questionnaire. Data analysis was performed with descriptive analysis, t-test, ANOVA, and multiple regression analysis using SAS(ver 9.2). Results : The levels of occupational stress and emotional labor in dental counselors were $47.26{\pm}8.36$ and $3.45{\pm}0.47$. Three subscales of emotional labor as frequency of emotional expression, attention of emotional expression norms and disharmony of emotion were related with occupational stress in dental counselors. The level of job stress was increased by the lower level of emotional expression and increased by the higher levels of emotional expression and disharmony of emotion. Conclusions : In addition to increasing the number of counselors, nurturing counseling workforce is essential to manage the job stress of dental counselors. Sufficient counseling with a patient in a comfortable counseling environment is important to reduce the job stress by emotional labor. Continuous service improvement through positive emotional service education is necessary to be implemented for counselors.

The purpose of this study was to identify the effects of work stress, burnout and compassion satisfaction of the estheticians. The sample consisted of 268 estheticians from esthetic-shop located in Seoul and Gyung-gi province. The questionnaire was organized into 4 items of general traits, 24 items of KOSS, and 10 items of burnout and compassion satisfaction from proQOL. Results show that estheticians experienced a greater than moderate degree of job stress, compassion satisfaction burnout, whereas differences existed according to general characteristics. but group was included in the top 75% of the factor on when compared to the Korean occupational stress scale. It is foreseeable that the burnout caused by the work of a estheticians is not small at all. This study is expected to be used as basic data in finding ways to reduce job stress and burnout of estheticians.

Purpose : The purpose of this study has been performed to find the relationship between seafarers' cumulative fatigue and stress by evaluating autonomic nervous functions and the results of surveys conducted using questionnaires. Methods : The subjects were seafarers working on various ships (home trade ships) of South Korea, who were healthy adults without any diseases, as confirmed through preliminary surveys were recruited through simple random sampling. A device that measures autonomic nervous functions by analyzing heart rate variability, which is also used often in clinical diagnoses and studies at universities, university hospitals, and general hospitals was used to measure the seafarers' cumulative fatigue and stress. Pearson's correlation analyses were also conducted to test the relationship between cumulative fatigue and stress measured by evaluating autonomic nervous functions and the results of surveys conducted with questionnaires. Results : There was no correlation between mean cumulative fatigue measured for each ship type and seafarers position through autonomic nervous functions evaluation and fatigue severity scale (FSS). There also was no correlation between the mean levels of stress measured for each ship type and seafarers position through autonomic nervous functions evaluation and survey scores of Korean occupational stress scale (KOSS). Conclusion : Therefore, in order to prevent man-made accidents in the sea among seafarers working with irregular port entry/departure schedules and under environments involving continued vibration, noises, and shaking, it is necessary to analyzed cumulative fatigue and stress scientifically and objectively, such as through autonomic nervous functions evaluation rather than through surveys.

We have conducted a 22 GHz very long baseline interferometry (VLBI) survey of 281 local (z < 0.05) active galactic nuclei (AGNs) selected from the Swift Burst Alert Telescope (BAT) 70-month ultra hard X-ray (14-195 keV) catalog. The main goal is to investigate the relation between the strengths of black hole accretion and the parsec-scale nuclear jet, which is expected to tightly correlate but has not been observationally confirmed yet. The BAT AGN Spectroscopic Survey (BASS) provides the least biased AGN sample against obscuration including both Seyfert types, hence it makes an ideal parent sample for studying the nuclear jet properties of an overall AGN population. Using the Korean VLBI Network (KVN), the KVN and VERA Array (KaVA), and the Very Long Baseline Array (VLBA), we observed 281 objects with a 22 GHz flux > 30 mJy, detecting 11 targets (~4% of VLBI detection rate). This implies that the fraction of X-ray AGNs which are currently ejecting a strong nuclear jet is very small. Although our 11 sources span a wide range of pc-scale morphological types, from compact to complex, they lie on a tight linear relation between accretion luminosity and nuclear jet luminosity. Our finding may indicate that the power of nuclear jet is directly responsible for the amount of black hole accretion. We also have probed the fundamental plane of black hole activity in VLBI scale (e.g., few milli-arcsecond). The results from our high-frequency VLBI radio study support that the change of jet luminosity and size follows what is predicted by the AGN evolution scenario based on the Eddington ratio (ƛ$_{Edd}$) - column density ($N_H$) plane, proposed by a previous study.

Purpose : The purpose of this study was to identify the degree of occupational therapist's sleep quality and examine the correlation between sleep quality and job stress. We also investigated the effects of the occupational therapist's sleep quality on job stress. Therefore, we aimed to investigate the importance of sleep quality and find a way to reduce job stress in occupational therapists. Methods : We conducted a study from November 7 to from December 23, 2022. To assess sleep quality and job stress, sleep quality of scale and Korean occupational stress scale-SF (KOSS-SF) were used. The general characteristics, sleep quality, job stress were examined using a frequency analysis and presented with descriptive statistics. The pearson correlation coefficient was used to determine, whether there was a correlation between sleep quality and job stress. To find what factors have and effect on job stress, we conducted a multiple regression analysis. A significance level of α=.05 was used to verify statistical significance. Results : First, average sleep quality score was 2.10±.19. Second, a significant correlation was found between sleep quality and job stress (p<.01). And As a result of the relationship between sleep quality sub-factors and job stress, day time dysfunction (r=.23, p<.01), restoration (r=.18, p<.05), difficulty of falling asleep (r=.38, p<.01). difficulty of awakening (r=.36, p<.01), satisfaction (r=.33, p<.01) and difficulty of maintaining sleep (r=.24, p<.05) showed a statistically significant relationship with job stress. Third, the sub-factors of sleep quality influencing job stress were difficulty of falling asleep (β =.26, p<.01), difficulty of awakening (β=.23, p<.01) and satisfaction (β=.21, p<.01). Conclusion : The results of this study, demonstrated the importance of sleep quality in affecting job stress. Therefore, follow-up studies are, necessary to develop interventions to improve, occupational therapist's sleep quality in the future.
