Purpose: The objective of this study was to investigate the relationships between sleep quality, fatigue, depression and health promoting behavior by shift-work patterns in university hospital nurses. Methods: A cross-sectional, descriptive survey was conducted using a convenient sample. The self-administered questionnaires were given to 165 nurses (shift workers 91, non-shift workers 74) employed in two university hospital located in Seoul and Gyeunggi-do. Data were collected from February to March, 2010. Results: The shift workers showed significantly lower sleep quality and health promoting behavior, and higher fatigue than non-shift workers. There were significant correlations between fatigue, depression and health promoting behavior in shift workers. There were significant correlations between sleep quality, fatigue, depression and health promoting behavior in non-shift workers. In multiple linear regression analysis, after controlling for total work experiences, predictor of health promoting behavior in shift workers was only fatigue (${\beta}$=-.29, p<.001). Predictors of health promotion behavior in non-shift workers were depression (${\beta}$=-.37, p=.002) and fatigue (${\beta}$=-.27, p=.023). Conclusion: This study failed to provide a clear explanation why sleep quality does not have a comparable effect on health promotion behaviors of shift-workers as well as non-shift workers. However, future research is needed to determine the various risk factors influencing on health promotion behaviors by which shift-work pattern exacerbates fatigue.

It has been controversial whether upper airway resistance syndrome (UARS) is a distinct syndrome or not since it was reported in 1993. The International Classification of Sleep Disorders classified UARS under obstructive sleep apnea syndrome (OSAS) in 2005. UARS can be diagnosed when the apnea-hypopnea index (AHI) is fewer than 5 events per hour, the simultaneously calculated respiratory disturbance index (RDI) is more than 5 events per hour due to abnormal non-apneic non-hypopneic respiratory events accompanying respiratory effort related arousals (RERAs), and oxygen saturation is greater than 92% at termination of an abnormal breathing event. Although esophageal pressure measurement remains the gold standard for detecting subtle breathing abnormality other than hypopnea and apnea, nasal pressure transducer has been most commonly used. RERAs include phase A2 of cyclical alternating patterns (CAPs) associated with EEG changes. Symptoms of OSAS can overlap with UARS, but chronic insomnia tends to be more common in UARS than in OSAS and clinical symptoms similar with functional somatic syndrome are also more common in UARS. In this journal, diagnostic and clinical differences between UARS and OSAS are reviewed.

There are numerous studies on relations between sleep and environmental factors such as noise, illumination and thermal conditions. Sleep is affected by the thermal environment. This study describes influence of thermal environment on skin temperature, sleep patterns and body movements using physiological and psychological measurements. The results are as follows: 1) The fluctuations of room temperature during sleep appeared skin temperature variations. The more room temperature is high, the more skin temperature is high in 22$^{\circ}C$, 26$^{\circ}C$, 30$^{\circ}C$. 2) A significant relation between body movement and skin temperature was found within room temperature. Under room temperature conditions of 22$^{\circ}C$, 26$^{\circ}C$, 30$^{\circ}C$, there were significantly higher rates of body movement in the room temperature(30$^{\circ}C$). 3) Uncomfortable after sleep in thermal environment is mostly under high temperature(30$^{\circ}C$), and they are about fatigue due to not enough sleeping. 4) The degree of indoor thermal temperature with sufficient sleeping is in 22.8 ∼ 27.8$^{\circ}C$.

Objectives : This study is for discovering the clinical Features of the sleep in ordinary symptoms based on the Sasang Constitution. The result of this study could be helpful to understand and to identify the patients as Soeumin in contrast with the other constitutions-Soyangin, Taeumin and Taeyangin. Methods : There were 1,229 patients(700 female), who answered the questionnaire about their ordinary sleeping patterns. They had been diagnosed, including their clinical Sasang Constitution, by the Sasang Constitution specialist at Bundang Oriental Hospital of Dongguk University. By applying the binary logistic regression analysis, we can measure the characteristics and the influence of ordinary sleeping patterns to the dependent variable(Sasang Constitution). Results : As a result of the binary logistic analysis on the observed questionnaire, we found the characteristics of the ordinary sleeping patterns on Soeumin in contrast the other constitutions. Firstly, Soeumin has a tendency that he wouldn't snore well in comparison with the others. Secondly, Soeumin has a tendency that he will dreams more, when he sleeps in contrast with the others. Thirthly, Soeumin has a tendency that he will sleep longer than 6-7hours. Fourthly, Soeumin has a tendency that he will struggle during sleeping in contrast with the others. Conclustion : This study will be used to identify patients as Soeumin in contrast with the others-Soyangin, Taeumin and Taeyangin.

Objectives: This study examined the association of the sleep quality and patterns with the dietary behavior, including snack and beverage consumption, taste preferences, as well as lifestyle of university students. Methods: The subjects were 406 university students in Cheongju, Korea, and the data were collected using a self-administered questionnaire. They were divided into two groups according to the Pittsburgh Sleep Quality Index (PSQI): good-quality sleepers (PSQI score ≤ 5) and poor-quality sleepers (PSQI score > 5). The data were analyzed using a χ²-test, independent t-test, and analysis of covariance using the SPSS 25.0 program. Results: Fifty-two percent of university students were categorized as poor-quality sleepers by the PSQI. Students classified as poor-quality sleepers had delayed bedtimes, and a shorter duration in bed and total sleep hours than the good-quality sleepers did. Poor-quality sleepers were more prevalent among those who were female, having irregular mealtimes, or frequent late night meals. They also consumed fast food frequently, such as fried chicken and hamburgers, and noodles when adjusted for gender. In addition, drinks with caffeine over milk were dominant among poor-quality sleepers. Furthermore, the preferences for spicy and salty tastes and longer smartphone usage were more prevalent in those with poor-sleep quality. Conclusions: These results showed that more than 50% of university students reported disturbed sleep and poor quality sleep was associated with less desirable snack consumption and taste preference, more smartphone usage, and others. Therefore, nutrition education program along with lifestyle changes promoting sufficient sleep are encouraged to provide for university students, particularly those who have poor sleep quality.

목적 및 방법 : 수면무호흡증 환자들에서 상기도 압력 측정법을 이용하여 수면 중 기도협착의 형태를 연구하고, 각성시와 수면 중에 실시한 상기도 CT scan의 수면무호흡 중 기도 협착 부위의 예측도를 평가하기 위하여, 11명의 수면무호흡증 환자에서 4 압력 센서 또는 2 압력 센서가 달린 도관을 상기도로 삽입하여 상기도의 압력을 측정하면서 수면다원검사를 시행하고, 이 환자들에서 각성시와 수면 중에 상기도의 다섯 곳(high-retropalatal, low-retropalatal, retroglossal, hypopharynx, esophagus)에서 cine CT를 시행한 후 각 방법에 의하여 기도 협착 부위를 진단하고, 수면 중 상기도 압력 측정 결과에 의거하여 상기도 cine CT의 정확도를 평가하였다. 결 과: 상기도 압력 측정 결과 4명(36%)만이 수면 중에 단일 형태의 기도 협착을 보였고, 나머지 7명(64%)은 여러 가지 형태의 기도 협착을 보였다. Velopharynx가 수면무호흡시에 가장 흔히 관찰되는 기도 협착 부위였다(63.6%). 그러나, 상기도 cine CT결과는 수면무호흡 중에 8명이 단일 형태의 기도 협착을 보였다(72.7%). Apneic CT에서도 Velopharynx가 가장 흔한 기도 협착 부위였다. 상기도 압력 측정법과 상기도 CT 촬영법 사이의 기도 협착 진단의 일치율은 단 5명에서만 잘 일치하였고(high-concordant), 5명은 잘 일치하지 않았으며(low-concordant), 나머지 1명은 전혀 일치하지 않았다. 결 론: 대부분의 수면무호흡증 환자는 수면 중 여러 번 발생하는 수면무호흡에서 2가지 또는 그 이상의 기도 협착 형태를 보이므로, 단 1회의 수면무호흡의 상태만을 반영하는 상기도 CT는 수면무호흡의 기도 협착 부위를 적절히 반영하지 못한다고 생각된다.

Purpose : The aim of this study was to compare shift satisfaction, sleep, fatigue, quality of life (QOL), and patient safety incidents between a newly implemented two-shift system and a traditional three-shift system. Methods : A total of 127 intensive care unit nurses (48 two-shift nurses and 79 three-shift nurses) working in a tertiary hospital in Seoul were recruited from January 1, 2017, to March 31, 2017. They completed a self-reported questionnaire about their work hours, shift satisfaction, sleep patterns, sleep quality, fatigue, QOL, and patient safety incidents in the past 2 weeks. Data were analyzed using SPSS version 23.0. Results : The two-shift group showed higher shift satisfaction scores compared with the three-shift group (6.93 vs. 4.37, p<.001). Sleep latency was shorter and sleep quality was better in the two-shift group compared with the three-shift group. There were no significant differences in other sleep parameters, fatigue, QOL, and patient safety incidents between the two groups. Conclusion : Although a two-shift system did not improve nurses' fatigue or QOL in this study, it may effectively serve as an alternative shift-work system that can increase sleep quality and shift satisfaction without increasing patient safety incidents.
