Background: This study aimed to identified the relationship between the risk of obstructive sleep apnea, subjective health, and health-related quality of life among the middle-aged and elderly population in Korea. Methods: Adults aged 40 or older were extracted from the total 22,559 respondents to the 2019-2020 Korea National Health and Nutrition Examination Survey VIII, and secondary analysis was conducted on a total of 6,659 middle-aged and elderly people with no missing values. Logistic regression analysis and multiple regression analysis were conducted to examine the relationship between obstructive sleep apnea risk factors and subjective health as well as quality of life. Results: The subjective health status decline in the high-risk group compared to the non-risk group for obstructive sleep apnea was statistically significantly higher, with an odds ratio of 1.84 (p<0.001). The health-related quality of life was also statistically significantly lower by 0.02 points (β, -0.02; p<0.001). As a result of subgroup analysis on specific variables, the association between the risk of obstructive sleep apnea and subjective health and health-related quality of life was statistically significant depending on gender, sleep time, presence of depression, household income, and number of household members. Based on the obstructive sleep apnea risk group, women had a higher correlation with low subjective health and lower health-related quality of life scores than men. Sleeping time of more than 8 hours or less than 6 hours was more associated with low subjective health and lower health-related quality of life score than sleeping time of 6-8 hours. Patients with depression were more likely to have low subjective health than those without depression. The lower the household income level and the smaller the number of household members, the higher the association with low subjective health and the lower the health-related quality of life score. Conclusion: It is essential to recognize that the risk of obstructive sleep apnea not only directly affects sleep disorders but also impacts individuals' subjective health and quality of life. Consequently, social support and education should be provided to raise awareness of this issue. Particularly, programs for preventing and managing obstructive sleep apnea should target vulnerable groups such as women, individuals in single-person households, low household income, and those with depression, aiming to improve their subjective health and quality of life.

Purpose: This study was performed to verify the effect of rhythmic activity program on the elderly particularly their level of instrumental activities of daily living(IADL), depression and sleep. Method: The design of this study is one-group pretest-post test design. Three self-reported questionnaires were used as follows: first, the IADL Scale developed by Lawton and Brody(1969) and revised by Suh(1996) for measuring IADL, second, the Geriatric Depression Scale developed by Sheikh and Yesavage(1986) and revised by Song(1991) for measuring depression, third, Korean Sleep Scale developed by Oh, Song, & Kim(1998) for measuring sleep aspects; fourth, the applied version of Facial Pain Scale developed by Wong & Baker(1988) and revised by Song(2004) for measuring sleep quality. Twenty-seven elderlies carried out 50 minutes of rhythmic activity program for 4 weeks. Before and after the experiment, they were tested for IADL, depression and sleep. Collected data were processed using the SPSS/WIN 12.0 program analyzed by the frequency, percentage, mean and paired t-test. Results: The improvement in IADL of the elderly was not enhanced significantly but depression and sleep disorders significantly decreased. Conclusion: Rhythmic activity program is an effective nursing intervention for the elderly.

It is necessary to control the room temperature for comfortable and deep sleep during a tropical night. We need to investigate thermal transport and parameter between human and environment for comfortable sleep. Therefore this study is performed to evaluate the comfortable room temperature based on the change of skin temperature under variations in thermal conditions and several reports. Five female subjects of 20~22 years with similar sleeping pattern were participated for the experiment. The subjects arrived in chamber at 9 pm and adapted to thermal circumstances during 2 hours. The sensors was sticked in body for skin temperatures. If subjects fall asleep in chamber, lights off and then sleep during 8 hours.As results, indoor temperature range for comfort sleep was $23.9{\sim}28.4^{\circ}C$ based on comfort mean skin temperature. But considering transition of time, minimum indoor temperature was $21.6^{\circ}C$, $22.9^{\circ}C$, $24.1^{\circ}C$, $23.9^{\circ}C$ and maximum indoor temperature was $28.2^{\circ}C$, $30.1^{\circ}C$.

Purpose: This study aimed to confirm mediating effects of academic self-efficacy in the relationship between academic stress and sleep quality among academic high school students. Methods: The participants included 195 academic high school students who were attending a private educational institution in the Gwangju or Pusan metropolitan city. Data were collected from September 1 to September 30, 2019. The data were analyzed using PROCESS macro SPSS/WIN 3.2 and bootstrapping was used to test the mediating effects. Results: There were significant relationships between sleep quality and academic stress (r=-.55, p<.001), sleep quality and academic self-efficacy (r=.35, p<.001), and academic stress and academic self-efficacy (r=-.16, p<.020). Academic self-efficacy showed partial mediating effects in the relationship between academic stress and sleep quality. Conclusion: These findings suggest that the development of a program that improves the academic self-efficacy of academic high school students who are experiencing academic stress is a way to improve the quality of their sleep.

Objectives : Firefighters frequently experience traumatic events, high-tension situations and shift work. Therefore, the prevalence of insomnia of firefighters is higher than one of general population. Not only does the quality of sleep affect the satisfaction of personal life, but it also influences their performance for the public's safety. We investigated which factors affect the quality of sleep of firefighters. Methods : After personally delivering 120 questionnaires to 3 fire stations, the survey was conducted when the consents were signed. It inquired about alcohol use, smoking, shift work, sleep quality, depression, anxiety, and experience of traumatic events. We then divided the firefighting officers in two groups according to the quality of sleep and compared the variables examined to conduct the logistic regression analyses according to the results. Results : The poor sleeper group reported a higher level of current alcohol consumption, depression, anxiety and experience of traumatic events. Logistic regression analyses showed that the current alcohol intake (Crude odds ratio=3.707, 95% confidence interval=1.288-10.672, p=0.015 ; Adjusted odds ratio=3.288, 95% confidence interval=1.011-10.694, p=0.048) has a significant effect on sleep quality. Conclusions : Current alcohol consumption, depression, anxiety and experience of traumatic events were respectively associated with sleep quality of firefighters. When all significant factors considered, the current alcohol use was the only statistically significant. To improve the quality of sleep for firefighters, it will be necessary to evaluate alcohol intake, educate the poor sleep quality caused by alcohol, and provide specific interventions to reduce consumption.

Objectives: We investigated whether sleep behaviors, severity of insomnia and circadian typology are associated with quality of life among Gyeongsang National University (GNU) medical students. Methods: Questionnaires were distributed to 46 fourth-year students of GNU Medical School. The hospital anxiety-depression scale, insomnia severity index (ISI), morningness-eveningness questionnaire (MEQ) and WHO Quality of Life-BREF (WHOQOL-BREF) were used. Results: Quality of life in terms of physical health was associated with age, weekday total sleep time (TST), weekend TST, catch up sleep, depression, ISI score, and MEQ score. Quality of life in terms of psychological health was correlated to weekday and weekend TST, anxiety, ISI score and MEQ score. Sex, weekday TST, depression, and ISI score were revealed to influence the social aspect of quality of life, and weekday and weekend TST, and ISI score were associated with quality of life in terms of environment. Multiple regression analysis showed that better sleep quality predicted to a higher quality of life in terms of physical, psychological and environmental health, and eveningness was associated with a better quality of life in terms of physical and psychological health. Conclusion: It is concluded that physical, psychological, and environmental aspects of quality of life were associated with quality of sleep and that physical and psychological aspects of quality of life were related to eveningness in GNU medical students. Therefore, it is equally important to treat emotional problem as well as improve sleep quality.

This study identified the differences and relationships between clinical practice stress, sleep quality, and daytime sleep disorder before and after clinical practice of college nursing students. The subjects were 130 students in the third year of nursing science. The results showed that the average clinical stress of the study subjects was 3.15 out of 5 points. Out of the external factors for clinical practice stress, the score for the task was 3.64. There was a significant difference in gender (t=-3.88, p<).001), subjective health status (F=5.78, p=.004), residence (F=3.20, p=.026). Nursing students showed lower sleep quality (80.0% before practice, 70.0% after practice), and those with daytime sleepiness (26.9% before practice, 42.3% after practice) were more than those of general college students. There was a difference between sleep quality (χ²=4.06, p=.004) and daytime sleepiness (χ²=6.08, p=.009) before and after clinical practice. There was also a negative correlation between daytime sleepiness and sleep quality (r=-.259, p<0.01). Therefore, strategies to reduce clinical practice stress and improve the quality of sleep are needed for the physical and mental health of nursing college students. The quality of nursing can be improved in the future by helping nursing students adapt to the clinical practice of changing nursing education field.
