The purpose of this study was to investigate the factors related to problem drinking in male workers according to occupational classes. Data were derived from the 2012 Korean National Survey on male workers. A total of 391 office workers, 707 manufacturing workers, and 309 service workers participated in this study. Data were analyzed using Rao-Scott $X^2$-test, simple and multiple logistic regressions. Problem drinking was defined as ${\geq}8$ points in the Alcohol Use Disorders Identification Test. The problem drinking rates were 45.1% in office workers, 39.1% in manufacturing, and 42.3% in service. In office workers, the factor related to problem drinking was only smoking. In manufacturing workers, the factors related to problem drinking were spouse, smoking and prevalence of Diabetes. In service workers, the factors related to problem drinking were age and smoking. Therefore, different intervention should be developed for each occupational class in order to manage the problem drinking in male workers.

Objectives: The purpose of this study was to determine the effectiveness of hand acupressure in relieving shoulder pain among male manufacturing workers. Methods: A nonequivalent control group was employed using a nonsynchronized design. Data were collected from two manufacturing plants located in metropolitan area U. The data were analyzed with a ${\chi}^2$-test and an independent t-test to perform a homogeneity test, and with repeated ANOVA measures to perform an hypothesis test using the SPSS 21.0 program. Results: Hypothesis 1 that "the experimental group provided with hand moxibustion would score lower for low shoulder pain than the control group" was supported (F=306.05, p<.001). Hypothesis 2, that "the experimental group provided with hand moxibustion would have a wider range of motion than the control group" was also supported with increased flexion(F=7.73, p<.001), extension(F=7.89, p=.001), abduction(F=21.23, p<.001), and horizontal abduction(F=20.89, p=.028). Hypothesis 3, that "the experimental group provided with hand moxibustion would score lower for quality of sleep than the control group" was not supported (F=56.10, p=.091). Conclusions: Hand moxibustion is effective in relieving shoulder pain for male manufacturing workers, in relieving low shoulder pain and increasing the range of motion.

Purpose: This study was conducted to understand the effects of daily hassle stress on the psycho-social health of male workers in manufacturing industry. Methods: Daily hassle stress and psycho-social health in manufacturing industry workers were estimated by using the Daily Hassles Scale for Korea Workers (DHS-KW) and general health questionnaire (GHQ), respectively. Results: The subjects were 553 male workers who had never been occupationally exposed to hazardous chemicals, were mean age 39.6 years and mean work duration was 15.66 years. DHS-KW total mean score had significantly higher in young ages (twenties and thirties ages), office workers, managers and daytime workers than other groups. GHQ total mean scores were significantly higher in un-married, daytime and overtime workers than others. DHS-KW and GHQ score correlated that they were negative correlation with age and working years, but was positive correlation with working hours and overtime work. The significant correlation between DHS-KW and GHQ were observed almost variables of DHS-KW and GHQ except a domestic and daily problem in DHS-KW variables. Domestic and daily problems were only significantly correlated with anxiety and insomnia of GHQ variables. Conclusion: This study indicated that physical health was associated with work condition and psychsocial health was mainly associated with domestic and daily problems of DHS-KW variables. Thus, the study on Daily Hassles stress and related with work stress should be further investigated for the comprehensive health program including stress management and coping behavior.

Background: The purpose of this study is to investigate the relationship between job stress and impaired fasting glycemia (IFG) of male workers in a manufacturing industry. Methods: Data were collected from 5,886 male workers in a manufacturing industry who participated in the medical examination from June 19 to August 14, 2020 through self-reported questionnaires. The general characteristics of the subjects, shift work, high blood pressure, dyslipidemia, and job stress were included. Job stress was measured using the Korean Occupational Stress Scale (KOSS) consisting of 8 items and 43 questions. Multivariable logistic regression analysis was used to investigate the IFG association with job stress. Results: Among the various factors that can cause job stress, only high job demand was associated with a risk of IFG (odds ratio, 1.43; 95% confidence interval, 1.13-1.82) especially in non-shift worker. For all other factors, no statistically significant results were obtained. Conclusions: In this study of male workers engaged in the Korean steel manufacturing industry, the 'job demand' item among job stress of non-shift worker was related to IFG.

Background: Circadian rhythm disturbance caused by shift work has adverse effects on the metabolic homeostasis of the liver. Disruption of the metabolic homeostasis of the liver causes fat accumulation in the liver. The aim of this study was to investigate the correlation between shift work and non-alcoholic fatty liver disease (NAFLD) among male workers in the steel manufacturing industry of Korea. Methods: Based on medical examination data collected in June 2020, 2,511 male subjects from one steel manufacturing company in Korea were selected in total. NAFLD was evaluated using abdominal ultrasound, which was performed by two experienced radiologists. The multinomial logistic regression analysis was performed by adjusting for age, physical activity, smoking history, alcohol consumption, body mass index, waist circumference, blood pressure, blood glucose, lipidemia, liver function test, employment duration, and hepatotoxic materials exposure status. Results: Compared to daytime workers, the odds ratio (OR) of moderate-severe NAFLD in shift workers was 1.449 (95% confidence interval [CI], 1.028-2.043). Compared to daytime workers, the ORs of moderate-severe NAFLD were significantly higher for the group that engaged in total shift work for more than 20 years (OR, 2.285; 95% CI, 1.051-4.970), the group that was not allowed to sleep during night shift work (OR, 1.463; 95% CI, 1.030-2.078), and the group that consumed food during night shift work (OR, 1.580; 95% CI, 1.093-2.284). Conclusions: There was a correlation between shift work and moderate-severe NAFLD in male steel manufacturing workers. There will be a need for more research related to the correlation of shift work with steatohepatitis and cirrhosis in the future.

Objectives: This study was conducted to assess the level of depression and its association with sociodemographic characteristics and health related characteristics, job-related characteristics, sleep quality, occupational stress among manufacturing male immigrant worker in Korea. Methods: Total number of subject were 287 workers employed in 19 manufacturing industry. A structured self-administered questionnaire was used to assess each responder's sociodemographic and health related characteristics, job-related characteristics, sleep quality (PSQI), Korean occupational stress (KOSS), Depression (CES-D). The job stress questionna ire was used according to KOSS-26 and depression symptoms were measured using CES-D, which was translated into Korean. We used multiple logistic regression analysis to assess the relationship between risk factors included job stress, sleep quality and depression. Results: The prevalence of depression in survey subjects was 63.9%and poor group (PSQI) (5 point and over at PSQI score)among all subjects were 83.28%. Adjusting for confounding factor, higher the occupational stress (KOSS), depression levels were significantly higher (${\beta}=0.5575$), worse quality of sleep, the more depressed the level was slightly high ${\beta}=0.118$) did not reach statistical significance. Conclusions: The prevalence of depressive symptoms among the study subjects was higher than that among the Korean workers. Especially, the level of depression was more influenced by occupational stress than quality of sleep. Therefore, the author recommend to prepare the effective strategy for reducing the depression and also reducing the occupational stress among immigrant male workers, and the author consider that it need to support the convenient working environment such as consultation for difficulty or health care among immigrant male workers.

This study was conducted to investigate the relationship between sleep quality and depression level of male workers in the manufacturing industry. The survey subjects were 856 male workers in the manufacturing industries in D city. Data collection was conducted through a self-administrated questionnaire survey during the period from March 1 to April 30, 2019. The distribution of depressive level among subjects differed significantly according to various variables of sociodemographic characteristics, health related behaviors and job related characteristics. In addition, the distribution of the depressive group was significantly higher in the group with worse quality of sleep (PSQI). Depression level showed a significant positive correlation with sleep quality. The risk ratio of the depressed group was significantly higher than that of the sleep quality. The results of this study suggest that the depressive level of male workers in the manufacturing industry is significantly related to the quality of sleep as well as sociodemographic, health related and job related characteristics. Therefore, it is necessary to make efforts to improve sleep quality to reduce the level of depression of workers.
