Background: This study aims to allow the development of efficient measures to improve occupational health of shift-working nurses focusing on job stress, health promotion behavior, resilience, and sleep disturbance. Methods: It was conducted on a subject panel of 137 nurses who were aware of the purpose of the study and agreed to participate. They worked three shifts at a tertiary hospital or a general hospital located in metropolitan city B. The collected data were analyzed by the independent t test and one-way analysis of variance and post-tested by Scheffe's test, Pearson's correlation coefficients, and multiple linear regression analysis using SPSS/WIN 25.0. Results: The significant influencing factors on sleep disturbance were of those whose subjective health status was 'normal' (b = 0.29, p < .001), 'not healthy' (β = .40, p < .001), who have job stress (β = .22, p = .003), and who have health promotion behavior (β = -0.17, p = .023). The overall explanatory power was 31.1% (F = 16.31, p < .001). Conclusion: Through this study, nurses' subjective health status and job stress of working shifts were found to be important factors influencing the sleep disturbance level, and the most influencing factor was identified as the subjective health status.

Objectives : Disturbance of sleep with or without sleep apnea may impair the memory function. Sleep deficiency, sleepiness, sleep apnea and emotional problem in sleep disorders can induce an impairment of memory function. Methods : In this study, the polysomnographies were administered to 58 sleep apnea patients and 38 sleep disorder patients without sleep apnea. Their clinical symptoms were quantitatively evaluated. Short term and long term memory were evaluated before and after polysom no graphy with Digit symbol test and Rey-Osterrieth complex figure test. And correlations among various sleep, repiratory and clinical variables were statistically studied in order to explore which variables may influence on memory function. Results and Conclusions : Results are as follows. Depth of sleep cis positively correlated with memory function. As sleep apnea increases and average saturation of blood oxygen decreases, memory function is more impaired. Emotional depression, high blood pressure, obesity or alcohol impaired memory function. However, daytime sleepiness was not significantly correlated with memory function. The possible mechanisms how above factors influence on the memory function were discussed.

Snoring and obstructive sleep apnea are the representative sleep disordered breathings, caused by the temporary and repetitive constriction or obstruction of upper airway during sleep. They present with excessively vibratory noise and repetitive cease of respiration. These disorders commonly result in sleep disturbance and the subsequent daytime sleepiness, chronic fatigue. Furthermore, they can cause the serious and extensive complications including increased risk of hypertension, cardiac arrhythmia, cardiovascular disease, cerebrovascular accident, neurocognitive disturbance, traffic and occupational accidents, type II diabetes, childhood growth interruption, awakening headache and finally, relatively increased mortality rate. Because appropriate therapeutic intervention is best way for patients to relieve their symptoms and prevent their possible complications, it is very important for dentists to recognize their own role and responsibility in diagnosis and treatment of these disorders. For this, the present article provides the understanding of the clinical features, possible complications, various treatment modalities, and suitable treatment strategies for snoring and obstructive sleep apnea.

본 연구는 입원 중인 아동의 수면양상의 변화 및 수면방해 요인을 파악하기 위한 기초 연구이다. 본 연구는 구조화된 설문지를 이용하여 상급종합병원에 입원한 6세 이하 아동 81명을 대상으로 하였으며, 자료 분석은 SPSS/WIN 21.0을 이용하였다. 본 연구의 결과 아동의 수면시간은 입원 전에 비해 입원 후 유의한 수준으로 감소하였으며(p<.001), 수면잠복기(p<.001)와 수면 박탈 횟수(p<.001)에 차이가 있었다. 돌봄 제공자인 어머니가 인식하는 아동의 수면방해 요인은 아동의 건강 상태, 병실 내 소음, 간호사의 처치, 병실 내 조명 등이었다. 본 연구를 통해 아동의 입원 시 수면의 시간과 질이 감소한 것을 확인할 수 있었다. 입원 아동의 수면양상의 변화와 방해 요인을 파악한 연구를 바탕으로 입원 아동의 수면 증진을 위한 방안 마련이 필요하다.

As the demand for quality sleep increases in modern society, the importance of sleep technology has increased. Recently, development of sleep environment improvement products and research on the user's sleep improvement have been activated. Representatively, user sleep pattern analysis research is being conducted through the existing polysomnography, but it is difficult to use it in the sleep environment of daily life. Therefore, in this paper, we propose a system design that can provide a customized deep sleep service to users by detecting sleep disturbance factors in a motion bed environment. In order to improve the user's sleep satisfaction, a logistic regression-based sleep pattern analysis model is proposed and accuracy and significance are verified through experiments. And to improve user's sleep satisfaction, we propose a logistic regression-based sleep pattern analysis model and verify accuracy and significance through experiments. The proposed system is expected to improve the user's sleep quality and effectively prevent and manage sleep disorders.

This study was attempted to show basic data for search of nursing intervention about sleep improving in home and institute elderly peoples. Research design was cross-sectional survey method for comparison of sleep patterns and another variables between home and institute elderly peoples. Subjects were sampled by purpose as home and institute elderly peoples at age of 65 or older in Seoul or nearly. The survey questionnaire was used by modification of sleep questionnaire which Kim, O, Song & Bak(1997) developed. Data were collected between December, 1999 and April, 2000. And data were analyzed by SPSS PC+ for purpose of research. Results are as follows: 1. Home and institute elderly peoples, all were change of sleep patterns and sleep pattern was showed early sleeping down. But institute elderly peoples slept earlier than home elderly peoples. 2. As rest of morning, difficulty of falling asleep and disturbance of re-asleep, subjective thinking and feeling were showed more negative thing home elderly peoples than institute elderly peoples. As frequency of falling asleep within 5 min in 1 week, frequency of falling asleep over 30 min in 1 week and frequency of awakening in a day, objective frequency were showed more insomnia institute elderly peoples than home elderly peoples. Home elderly peoples didn't nap most and institute elderly peoples napped on very short time. 3. Regarding sleep-disturbing factors, physical factor was popularly joint-disturbance in all, home and institute elderly peoples. Environmental factor was popularly noise, particularly institute elderly peoples. Emotional factor wasn't all. 4. Practiced strategies for better sleep was popularly TV/Radio in home elderly peoples and were popularly regular sleep and religious action in institute elderly peoples. From the results of this study, home elderly peoples need nursing intervention of improving self-satisfaction on sleep and institute elderly peoples need nursing intervention of decreasing falling asleep-disturbing and decreasing frequency of awakening in sleep.

연구목적 : 수면 무호흡의 증상은 크게 불면증, 낮의 과다한 졸리움, 기억력과 집중력 등의 인지기능장애, 우울 등의 감정장애 등이 주 증상을 이루고 있다. 그런데 이러한 증상들이 수면 및 수면 무호홉의 여러 변수들과 어떤 상관관계를 가지며 어떤 과정을 통해서 구체적으로 발생되는 지에 대한 연구는 그렇게 많지 않다. 연구방법 : 본 연구는 수면 무호흡증 환자 60 명을 대상으로 수면다원검사를 실시함과 동시에 낮 졸리움 척도, 불면증 척도, 인지기능 척도 및 감정장애 척도를 통해 수면 무호홉의 증상을 평가하였다. 그리고 수면다원 검사상의 여러 수면변수, 무호흡의 횟수, $O_2$ desaturation, 코골기 정도 등과 무호흡 증상의 4 가지 척도와 상관관계를 조사하였다. 연구결과 : 유의한 상관관계를 보인 결과는 다음과 같다. 무호흡 환자 중 불면증호소가 적고 비교적 잠을 잘 자는 경우는 호흡장애가 많은 경우와 중심성 무호흡이 많은 경우였다. 그리고 제 3 단계 서파수면에서 코골기가 많거나 경등도의 산소저하가 많은 경우였다. 대신 낮에 졸리움증이 많은 경우는 제 1 단계에서 코골기가 많은 경우였다. 그러나 무호흡의 정도나 산소와는 직접 상관관계가 나타나지는 않았다. 우울 등의 감정장애는 수면 중 산소저하가 중등도이상으로 심한 경우 많이 나타났으며 제 4 단계 서파수면이 적은 경우 이러한 우울 감정이 더 심하게 나타났다. 집중과 기억 등의 인지기능은 REM 수면이 많고 호흡장애의 횟수가 적을수록 더욱 감소되는 현상을 보였다. 결론 : 무호흡의 증상은 서로 다른 원인과 기전을 통해 발생될 수 있으며 이러한 증상을 좀 더 객관적 평가할 수 있다면 환자의 수면 및 무호흡의 정도와 상태를 예측하는데 더욱 많은 도움을 줄 수 있을 것으로 기대된다.
