기온이 높고 습한 여름이면 불면증이나 수면장애를 호소하는 사람이 많다. 또한, 스트레스, 불안감 등으로 인한 심리적인 이유로 밤에 잠 못 이루는 사람들도 많다. 수면을 위해 수면제를 먹는 것은 일시적인 도움은 될 수 있으나 수면제 장가복용으로 이어질 수 있다. 음주는 오히려 수면을 방해할 뿐이고 샤워를 하는 것도 수면에 방해될 뿐이다. 그렇다면 수면을 돕는 색채와 명화의 도움을 받아보는 것은 어떨까.

This was a basic study to ascertain the changes in sleep patterns and the factors disrupting sleep in hospitalized children. The participants were children aged 6 years or younger who had been hospitalized in an advanced general hospital in a particular region. A total of 81 participants were included, and for data analysis using SPSS/WIN 21.0. The results showed that children's sleep duration decreased significantly after hospitalization compared to before (p<.001), and there were significant differences in sleep onset latency (p<.001) and frequency of sleep deprivation (p<.001). Factors perceived by the children's mothers to disrupt sleep included the child's health state, noise in the ward, nurses' treatments, and lighting in the ward. This study verified that children's sleep quality and duration decreases during hospitalization, demonstrating the need to prepare measures to improve sleep in hospitalized children based on an understanding of changes in sleep patterns and disrupting factors.

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.

문명의 발달과 함께 인간은 사회생활의 증가와 부족한 수면으로 인한 스트레스와 병이 증가하고 있다. 따라서 수면에 대한 관심이 증가하면서 편안하고 쾌적한 수면을 위한 수면환경에 대한 연구가 진행되어지고 있다. 본 연구는 쾌적한 온열환경 제시를 위한 방법으로서 여름철 실내환경이 수면에 미치는 영향을 알아보기 위해 22$^{\circ}C$, 26$^{\circ}C$, 3$0^{\circ}C$의 3가지 온도조건을 제시하고 5명의 피험자를 대상으로 수면다원검사를 실시하여 EEG, EOG, ECG, EMG 등의 생리신호를 측정하였다. 측정된 생리신호를 통해 수면단계분석과 수면효율을 분석한 결과 총 수면시간, SWS latency, 총 수면시간에 대한 SWS 시간의 비율이 26$^{\circ}C$의 조건에서 가장 좋은 결과를 나타내었으며, 22$^{\circ}C$, 3$0^{\circ}C$의 순서로 나타났다. 이러한 분석을 통해 온도차에 따라 수면상태가 달라짐을 관찰할 수 있었고, 여름철에 26$^{\circ}C$ 정도의 실내온도가 편안하고 쾌적한 수면을 위한 실내온열환경임을 알 수 있었다.

Purpose: This study is a retrospective descriptive study to investigate the factors affecting sleep quality of Obstructive Sleep Apnea (OSA) patients. Methods: Data were collected from questionnaires and electronic medical records of 176 patients with obstructive sleep apnea were reviewed from 2017 to 2018. The collected data was analyzed into descriptive statistics, t-test, Pearson's correlation, and multiple regression analysis. Results: The mean age of the subjects was 49.37 years and 94.4%(n=166) had low sleep quality. The quality of sleep of the OSA patients had correlations with daytime sleepiness, and depression. The significant factors influencing quality of sleep were Gender(${\beta}=.18$, p<.004), depression(${\beta}=.50$, p<.001), dry mouth (${\beta}=.15$, p<.016), Headache(${\beta}=.17$, p<.008), explained 37.1% of the variance. Conclusion: To improve their sleep quality, required for OSA patients who have the depression, daytime sleepiness.

Purpose: Purpose: This study was to study the effect of foot bathing on menopausal symptoms and sleep disorders in female subjects in their 50s with menopausal symptoms. Methods: After 12 weeks of foot bath therapy three times a week, pre- and post-menopausal signs were measured. Results: Subjects with hot flashes, heart discomfort, sleep problems, depression, irritability, anxiety, physical and mental fatigue, sexual problems, urination problems, vaginal dryness, and joint and muscle discomfort significantly improved after than before(p < .001). Subjective sleep quality, sleep incubation period, sleep duration, sleep disturbance score, sleep drug use, and sleep dysfunction significantly decreased after foot bath than before(p < .001). Habitual sleep efficiency increased considerably. Conclusions: The subjects showed overall improvement in menopausal symptoms and sleeping quality after a foot-bath. Therefore, foot bath therapy is evaluated as a natural healing therapy suitable for improving menopausal symptoms and sleep.

Sleep is very important physiology to our human, about one third of human life was sent over to sleep. This paper measures of sleep and proposes sleep quality and future direction in order to improve the sleep environment. Sleep measure was determined by using X2 histogram that is one of the scene change detection method. X2 histogram method is one of the statistical scene change detection and is used in many studies because of the histogram method performs better than the other. And find out their relationship by entering the degree of fatigue, alcohol, and hungry in order to develop quality of sleep and extracting to tossing and turning according to each situation.

This paper introduces the IoT-based service 'RapportRapport' using arduino and mobile application that focuses on consistency and repetition to manage bedtime routine - the core part of sleep education. It is necessary for baby's better sleep outcomes, including deep sleep and long sleep duration. 'RapportRapport' provides Arduino dolls with sensors attached to provoke sleep association to baby, and to help user's bedtime routine efficiently at the same time. Arduino and mobile application exchange data by communicating via bluetooth.

The sleep stages provides the most basic evidence for diagnosing a variety of sleep diseases. for staging sleep by analysis of EEG(electroencephalogram), it is especially important to detect the characteristic waveforms from EEG. In this paper, sleep EEG signals were analyzed using Fourier transform and continuous wavelet transform as well as discrete wavelet transform. Proposeed system methods. Fourier and wavelet for detecting of important characteristic waves(hump, sleep spindles. K-complex, hill wave, ripple wave) in sleep EEG. Sleep EEG data were analysed using Daubechies wavelet transform method and FFT method. As a result of simulation, we suggest that our neural network system attain high performance in classification of characteristic waves.

In this paper, provide the optimal sleep environment of individual by extracting the simulation model based on that collect sleep environment data of bedroom to sleeping, and analyzing the relationship between conditions with obtained data and sleep. In addition, it was to provide a more stable sleep solution by defining different and pattern from sleep situation according to physical condition such as fatigue ratio, alcohol ratio, fasting ratio, etc. depending on the sleep process. Therefore, it change the proper indoor environment and help to enjoy life more pleasant.
