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.

Objectives: Insomnia is a common condition that causes deterioration of cognitive function and physical function and has a negative impact on quality of life. Insomnia is experienced by more than one-third of the population of the world. Although sleeping pills are currently used as therapeutic agents, they have side effects, so safer treatment methods are needed. Therefore, we report a case of an outpatient who sleeps only one hour a day due to insomnia. Methods: The patient visited Korean Medicine Hospital 10 times for four weeks and was treated with Korean medicine therapies, including electroacupuncture on the back-Shu points and herbal medicine (Yukmijihwang-tang and Hwangnyeonhaedok-tang). Treatment progress was assessed using the Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI). Results: After 29 days of treatment, the PSQI score decreased from 20 points and 14 points. The ISI score also decreased to decreased to 22 points from 26 points. The average daily sleeping time increased from 60 minutes to 197.1 minutes after treatment. No significant side effects were observed. Conclusions: Yukmijihwang-tang and Hwangnyeonhaedok-tang with electroacupuncture might be a recommended therapeutic option for insomnia patients.

Purpose : The purpose of this work was to ascertain the effects of cervical traction on the pain, the range of motion and the quality of sleep of the older women with the tension headache. Method : 25 subjects between ages 66 and 82 who agreed on this experiment and diagnosed with tension headache participated in this study. All subjects were treated with air-pressure cervical traction while 20 minutes a day, 3 times per week, for 4 weeks. The effects of air-pressure cervical traction were evaluated by PSQI(Pittsburgh sleep quality index), a pain last a day, VAS, and four ROMs. In order to investigate the effect of age on the treatment, subjects were divided into two groups, of less and of over than age 75. The measured data were analyzed by using one-way repeated ANOVA and two-way repeated ANOVA. Result : 1) The group of less than age 75 showed the significant improvements in all measurement variables, PSQI, a pain last a day, VAS and four ROMs. 2) The group of over than age 75 showed the significant improvements in all measurement variables excluding the flexion ROM of cervical. 3) No significant differences between two groups were showed in all measurement variables, but the interaction effect between group and period was significant in only VAS. Conclusion : From the results of this study, a cervical traction intervention using an air-pressure cervical traction proved to be effective on the reduction of tension headache and the improvement of the quality of sleep.

Objectives : This study aimed to investigate the relationship between cold feet and sleep quality using polysomnography (PSG) and Pittsburgh Sleep Quality Index (PSQI). Methods : We divided 11 adults (6 females, 5 males) with Insomnia Severity Index score below 21 into cold feet (CF) and a non-cold feet (NCF) group based on the median feet temperature (Taichong, LR3). PSG and PSQI were administered to assess sleep characteristics and subjective sleep quality. Results : CF group exhibited significantly lower time in bed, sleep period time, and total sleep time compared to NCF group. While there were no significant group differences in sleep latency, wakefulness after sleep onset, or total arousal index, NCF group had significantly lower minimum oxygen saturation and apnea-hypopnea index in REM (rapid eye movement) sleep compared to CF group. Although the PSQI score and the proportion of poor sleepers were both higher in the CF group (7.40 and 80%) compared to the NCF group (5.50 and 50%), these differences did not reach statistical significance. Conclusions : This study showed that foot temperature affects sleep characteristics and suggests the need to utilize PSG in sleep research in Korean medicine.

Background: This study aimed to examine the impact of chronotype on depressive symptoms and explore the mediating effects of sleep quality, pre-sleep cognitive arousal, and social jetlag in a sample of wage earners. Methods: A total of 3,917 waged workers were surveyed online in July 2022. Logistic regression and mediation analysis were used to assess the relationship between chronotype (morningness, intermediate, and eveningness) and depressive symptoms (Patient Health Questionnaire ≥ 5), and the mediating effects of Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Pre-Sleep Arousal Scale (PSAS). All analyses were adjusted for age, education level, income level, marital status, coffee consumption, alcohol consumption, physical activity, occupation, employment status, and working hours to calculate odds ratios (ORs). Results: The chronotypes of all the participants were divided into morningness (4.7%), intermediate (93.5%), and eveningness (1.8%). Multiple logistic regression analysis showed an increased risk of depression in the eveningness chronotype (OR: 2.96; 95% confidence interval [CI]: 1.51, 5.86). Regarding the mediation analysis, ISI mediated 28.44% (95% CI: 16.39-40.5), PSQI for 31.25% (95% CI: 19.36, 43.15), and PSAS-Cognitive Score (PSAS-C) for 23.58% (95% CI: 10.66, 36.50) of the association between chronotype and depressive symptoms. However, social jetlag did not significantly mediate this relationship. (percentage mediated = 0.75%, 95% CI: -3.88, 5.39) Conclusions: Evening chronotypes exhibit an increased risk of depressive symptoms, which ISI, PSQI, and PSAS-C partially mediated. This suggests that interventions to improve sleep quality and maintain adequate sleep habits may effectively prevent and treat depression in employees with an eveningness chronotype.
