This study used a convenience sampling method to find out the effect of healthy lifestyle habits of college students participating in leisure activities on sleep quality. The results are as follows. First, in majors according to the personal characteristics of college students, the arts and sports field showed higher exercise lifestyle habits than the natural field, and in leisure participation, college students participating in the sports field showed an effect on exercise lifestyle, health perception habits, eating habits, and subjective sleep. In the leisure activity period, it was found that students who participated in leisure activities for more than 3 years had an effect on exercise lifestyle, health perception habits, and daytime sleep. In leisure activity time, it was found that students who participated for 1-2 hours had an effect on exercise lifestyle, health perception habits, and eating habits. Second, it was found that bad lifestyle habits had an effect on sleep difficulties, and in daytime sleep, exercise lifestyle habits, bad lifestyle habits, and eating habits were found to have an effect.

This study examined the relationships sleep habits, daytime sleepiness, and problem behaviors. A cross-sectional survey design was used. Participants were 276 adolescents. Sleep habits, daytime sleepiness and problem behavior were measured by Adolescent Sleep Hygiene Scale (ASHS), Epworth Sleepiness Scale (ESS), and Korea-Youth Self Report (K-YSR), respectively. Data were collected from July to August, 2014 using self-reported questionnaires. Participants were middle school students, perceived their sleep time as enough and their sleep quality as good, have no problem behavior during sleep, and have no caffeinated drink for last a week were more likely to have higher score of sleep hygiene. Sleep habits score was associated negatively with daytime sleepiness and problem behaviors. Sleep impacts on physical growth, behavior, and emotional development of adolescent. Therefore, it is necessary to develop a sleep enhancement program for the good sleep habits of the adolescents, and to make efforts at home and school.

본 연구는 MEQ(Morning-Evening Questionnire)와 수면습관 설문지를 이용하여 일본 시모노세끼 시내의 20개 사업장 1143명(남 682명, 여 461명), 한국은 마산,창원 인근의 62개 사업장 1148명(남 1038명, 여 110명)의 작업자를 대상으로 일본어판 한국판 아침-저녁형 및 생활습관 조사를 실시했다. 그러나 한국 작업자 집단의 남녀간 자료수의 차이가 너무 커 본 연구에서는 여성의 자료는 제외하고 한국과 일본의 남성에 대해서만 분석했다. 한.일 근무자 모두 ME 득점은 연령이 높아짐에 따라 이침형 쪽으로 이동되어 분포했고, 양국의 평균 ME 득점은 한국의 경우가 일본보다 어느 연령층이나 유의하게 낮았다. 연령을 5개그룹(24세 이하, 25-34, 35-44, 45-54, 55세 이상)으로 크로조타입을 3개 집단(아침형, 중간형 저녁형)으로 분류한 뒤 수면습관을 검토한 결과 한국과 일본의 작업자 집단 모두 연령이 높아질수록 기상 및 취침시각이 빠르고 각 연령층에서도 아참형이 저녁형보다 빠른 것을 알 수 있다. 그리고 일본의 경우 평일의 수면시간은 연령에 따라 길어지고, 각 연령층에서도 아침형보다 저녁형이 짧지만 한국은 그런 경향 을 보이지 않았다. 또한 일본의 작업자가 한국의 작업자보다 취침시간은 빠르고, 기상시간은 늦은 경향을 보이고 있었다. 이러한 현상은 문화나 생활습관의 차이 때문으로 보인다. 이러한 결과에서 연령이 높아 짐에 따라 아침형 쪽으로 변화하며 생체리듬의 위상이 전진한다는 것을 추측할 수 있다.

Objective : This study aimed to investigate the mediating effect of play on the relationship between toddlers' sleep habits and problem-solving. Methods : In total, 1,734 participants were selected from the 3rd wave of the Panel Study on Korean Children. A structural equation modeling approach was utilized to examine the relationship among toddlers' play, sleep habits, and problem-solving, as well as to investigate the mediating effect of play. Results : The monthly age of the study participants ranged from 23 to 32 months, with 885 (51.0%) boys and 849 (49.0%) girls. The indirect effects of play on problem-solving skills (β = 0.137, p = .006) were statistically significant, but the direct effects of sleep habits on problem-solving skills (β = -.015, p = .871) and the total effect (β = 0.122, p = .057) were not significant. Conclusion : This study indicated that sleep habits did not have a direct effect on problem-solving ability, but that the indirect effects were significant and fully mediated by play. Incorrect sleep habits can negatively affect lifelong development. Therefore, parents would need to be aware of whether their child is developing good sleep habits during the toddler age.

To evaluate the effects of sleep habits on the powers of beta waves and the sensory motor rhythm of the electroencephalogram (EEG), female college student subjects were divided into four groups, according to their sleep habits, as follows: GSHG (Good Sleep Habit Group), CSHG (Common Sleep Habit Group: late bedtime), CSDG (Cognitive Sleep Disorder-Delayed Sleep Phase Syndrome Group), and NSDG (Non-cognitive Sleep Disorder-Delayed Sleep Phase Syndrome Group). Brain function was stimulated by reading a book for 3 min in the morning (9~12 am) and the EEG was measured. According to the results, the powers of the beta waves and sensory motor rhythm were not different during the resting period among the four groups. However, during the reading stimulation period, the powers of beta waves and the sensory motor rhythm in the GSHG were significantly greater than in the other groups ($p$ <0.05). Beta powers during stimulation also increased in all brain areas in the GSHG ($p$ <0.05). Interestingly, these were decreased in the frontal and temporal lobes in the CSHG by the reading stimulation ($p$ <0.05). On the other hand, sensory motor rhythm, which represents focusing efficacy, only improved in the GSHG. These results indicate that the brain's focusing function during the reading stimulation was not properly operating in the morning in the female college students who had a delayed bedtime and bad sleep habits.

Objectives : The purpose of this study is to analyse sleep habits and sleep disorders in the elderly population ased 65-84 years. Methods : Epidemiological survey was performed at home by means of semi structured interviews in the city of Pusan, Korea. Subjects were randomly selected. The questionnaire consisted of 128 items including demographic findings, sleep habits, sleep disorders, somatic illnesses, and psychological distresses. Results : (1) The mean retiring time was 10.28 h (SD 1.30 h) and the mean wake-up time was 5.24 h (SD 1.33 h). The mean duration of sleep was 5.63 h (SD 1.80 h). The mean sleep onset time was 44.51 min. The mean frequency of daytime napping was 2.49 (SD 3.23). The subjects reported they woke up an average of 2.05 (SD 1.59) times per night. All of the above results were not related to age or gender. However, the mean frequency of difficulty in initiating/maintaining sleep was 2.2 times for men and 3.2 times for women (p<0.05). (2) The prevalence of insomnia was 57.7% and was not related to age or gender. Difficulty in initiating sleep was the most commonly reported insomnia complaint(52.4%). Early morning awakening was reported by 50.0% of patients and difficulty in maintaining sleep was reported by 45.1% of them. Worrying in bed and physical pain were strong contributing factor to insomnia. Conclusions : The results of our study showed several characteristics of sleep habits in the elderly. Sleep disorder in old age is not inevitable or trivial. Since sleep disturbance in older adults is common and distressing, it has implications for general health and well-being. Active concern and therapeutic intervention for the sleep habits and sleep disorders in the elderly are needed.

This study was conducted to determine the association between quality of sleep (QOL) and the general characteristics, the health-behavioral factors, and the occupational characteristics of firefighting officers. The survey was conducted in October 2016 with a self-administered questionnaire using the Pittsburgh Sleep Quality Index (PSQI) developed by Pittsburgh University, targeting 600 male firefighting officers working at five fire stations in D city. As a result, the QOL of the study subjects measured by the PSQI revealed 13.2% to be good, and 86.8% to be poor. In relation to general characteristics and health habits, the rate of the group who had poor quality sleep was significantly higher in those with a lower subjective health status, in the non-smoking group, and in the low sleep-quality group, compared to the good sleep-quality group. For occupational characteristics, the rate of those with poor quality sleep was significantly higher in groups such as the fire suppression group, the shift work group, the hard physical labor group, the group with a lower sense of satisfaction in their work, and in the group classed as unfit for the job but who were not considering quitting their jobs, compared to their respective counterparts. Multiple regression analysis revealed factors of influence with explanatory powers of 24.4% for subjective health status, alcohol use, subjective quality of sleep, career, job position, and physical labor. The results of this study suggest that the quality of sleep for firefighting officers is significantly related to general characteristics, health-behavioral characteristics, and occupational characteristics.
