Sleep changes substantially with age. There is a phase advance in the circadian sleep cycle and increased waking after sleep onset. The elderly people wake more frequently during the night and experience fragmented sleep and excessive daytime sleepiness. The prevalence of sleep disorders increases with age, and the composition of sleep disorders in the elderly differs from that in the young. The most frequently encountered sleep disorders are psychophysiologic insomnia, sleep disturbance due to dementia, sleeprelated respiratory disorder, restless legs syndrome and periodic limb movement disorder, and REM sleep behavior disorder. To treat the elderly sleep problem appropriately, it is important to know how sleep pattern changes as we age and to understand the cause of sleep-related symptoms. This article will review the sleep physiology and common sleep disorders in the elderly.

Purpose: This study was done to examine the sleep pattern of ICU patients, as well as characteristics of, and factors related to sleep disturbances, and state anxiety. It was done to provide the basic data fur effective nursing interventions to improve quality of sleep for these patients. Methods: The participants were 104 patients who were admitted to the surgical ICU in a hospital in Seoul. To measure sleep patterns, the Verran and Snyder-Halpern Sleep Scale and the Sleeping Scale developed by Oh et al.(1998) were used. Characteristics of sleep disturbances were measured using the Sleep characteristics scale developed by Park(1999). To measure factors related to sleep disturbances, thirty items developed by Oh(1998) were used. Results: There was no statistically significant difference in the sleep patterns according to the general characteristics of the patients. The characteristics of sleep disturbances showed statistically significant differences in general and specific characteristics of sleep patterns but there was no statistically significant difference according to the general characteristics of the patients. There were significant negative correlations between factors related to sleep disturbances and general and specific characteristics of sleep patterns but there were no statistically significant difference according to the general characteristics of the patients. Conclusion: The results showed that the majority of patients staying in the surgical ICU experienced sleep disturbances and that the physical factor was the major factor of sleep disturbances.

Purpose: The purpose of this study was to compare the effects of hand massage provided with different intervals and periods on pain and sleep disturbance after orthopedic surgery. Methods: A non-equivalent control group pretest- posttest design was used. The subjects were admitted in an orthopedic hospital to get a surgery. They were divided into three groups. Group I (n=30) had hand massage every day. Group II (n=30) had hand massage every other day. Control group (n=31) had usual care. Data of all three groups were collected on the day before operation, POD (postoperative day) 6 and POD12. Hand massage was given for 2 and half minutes per hand. Results: Pain on POD6 of experimental group II was reduced more than those of control group. Pains on POD12 of both experimental groups were reduced more than those of control group. On POD6, only perceived sleep disturbance (PSD) was significantly different among groups. On POD12, PSD, total sleeping time, and sleep efficiency were more improved in the experimental groups. Conclusion: Hand massage was effective on the reduction of pain and sleep disturbance after orthopedic surgery. Applying hand massage on alternate day was effective enough. Also the effects were more obvious after 12 days.

본 논문은 수면 2기의 EEG 신호와 주성분 분석(principle component analysis)을 이용하여 수면 장애를 분류하는 방안을 제안하고 있다. 초기 특징을 추출하기 위해서 첫 번째 단계에서는 수면 2기의 EEG 신호가 고속 푸리에 변환(fast Fourier transforms)에 의해서 잡음을 제거하는 과정이 수행되었다. 잡음이 제거된 EEG 신호를 두 번째 단계에서는 주성분 분석을 이용하여 5개의 차원으로 축소하였다. 마지막 단계에서는 축소된 5개의 차원을 가중 퍼지소속함수 기반 신경망(neural network with weighted fuzzy membership functions, NEWFM)의 입력으로 사용하여 분류성능을 측정하였다. 분류성능에 있어서 정확도(accuracy), 특이도(specificity), 민감도(sensitivity)가 모두 100%로 나타났다.

Narcolepsy is characterized by sleep attack with excessive daytime sleepiness(EDS), cataplexy, sleep paralysis, and hypnagogic hallucination. Paradoxically, narcoleptics tend to complain of frequent arousals and shallow sleep during the night time despite their excessive sleepiness. However, nocturnal sleep fragmentation in narcoleptics is relatively ignored in treatment strategies, compared with sleep attack/EDS and cataplexy. In our paper, we attempted to investigate further on the poor nocturnal sleep in narcoleptics and to discuss possible treatment interventions. Out of consecutively seen patients at Seoul National University Sleep Disorders Clinic and Division of Sleep Studies, we recruited 57 patients, clinically assessed as having sleep attack and/or EDS. Nocturnal polysomnography and multiple sleep latency test(MSLT) were done in each of the subjects. We selected 19 subjects finally diagnosed as narcolepsy(mean age $26.0{\pm}18.3$ years, 16 men and 3 women) for this study, depending on the nocturnal polysomnographic and MSLT findings as well as clinical history and symptomatology. Any subject co-morbid with other hypersomnic sleep disorders such as sleep apnea or periodic limb movements during sleep was excluded. Sleep staging was done using Rechtschaffen and Kales criteria. Sleep parameters were calculated using PSDENT program(Stanford Sleep Clinic, version 1.2) and were compared with the age-matched normal values provided in the program. In narcoleptics, compared with the normal controls, total wake time was found to be significantly increased with significantly decreased sleep efficiency(p<.01, p<.05, respectively), despite no difference of sleep period time and total sleep time between the two groups. Stage 2 sleep%(p<.05), slow wave sleep%(p<.05), and REM sleep%(p<.01) were found to be significantly decreased in narcoleptics compared with normal controls, accompanied by the significant increase of stage 1 sleep%(p<.01). Age showed negative correlation with slow wave sleep%(p<.05). The findings in the present study indicate significant fragmentation of nocturnal sleep in narcoleptics. Reduction of REM sleep% and the total number of REM sleep periods suggests the disturbance of nocturnal REM sleep distribution in narcoleptics. No significant correlations between nocturnal polysomnographic and MSLT variables in narcoleptics suggest that nocturnal sleep disturbance in narcoleptics may be dealt with, in itself, in diagnosing and managing narcolepsy. With the objective demonstration of qualitative and quantitative characteristics of nocturnal and daytime sleep in narcoleptics, we suggest that more attention be paid to the nocturnal sleep fragmentation in narcoleptics and that appropriate treatment interventions such as active drug therapy and/or circadian rhythm-oriented sleep hygiene education be applied as needed.

Sleep is an inevitable part of human existence and a part of the dynamic quality of life. The purpose of this study is to explore sleep pattern changes and related factors of patients hospitalized. The participants are 158 patients hospitalized in one general hospital. The questionnaire was developed by modification of VSH sleep scale (1987). Open question was used for research of related factors. $SPSS/PC^+$ are utilized for data analysis. The results are as follows ; There is significant difference before and after admission in the sleep disturbance. There is retroverse significant difference before and after admission in the sleep effectiveness. There is no significant difference between two groups in the nap supplementation. The patients reported pain by reason of sleep latency and mid-sleep awakening and noise due to early awakening. The reasons for lack of sleep were pain and noise. The method for overcoming their sleep disturbance, most of the subjects waited with closed eyes, imaged by themselved and took medicate sleeping pills. Discomfort manifested in the case of insufficient steepness was fatigue, headache and aggressiveness.
