Purpose: This study was done to investigate clinical characteristics and risk factors for sleep disturbance in patients with prostate cancer. Method: Participants were recruited from P hospital outpatient clinic from March 23 to April 20, 2006, and 101 participants completed a questionnaire assessing general and clinical characteristics, sleep quality, physical symptoms and psychological symptoms such as anxiety and depression. The data was analyzed using the SPSS 12.0 program. Results: In this study, 29.7% of the patients reported sleep disturbance. Cancer diagnosis related factors which affected sleep disturbance were onset (55.3%) and aggravation (83.3%). Habitual sleep efficiency of patients with sleep disturbance was as follows: bedtime was 10 PM, wake-up time was 6AM, sleep duration was six hours and twenty minutes. Risk factors for the presence of sleep disturbance included metastasis, the presence of intestinal symptoms, depression and anxiety. Conclusion: Sleep disturbance is a frequent problem associated with prostate cancer and seems to be influenced by aggravation of illness and the presence of physical and psychological symptoms.

Sleep is an essential process maintaining the life cycle of the human. In parallel with physiological, cognitive, subjective, and behavioral changes that take place during the sleep, there are remarkable changes in the electroencephalogram (EEG) that reflect the underlying electro-physiological activity of the brain. However, analyzing EEG and relating the results to clinical observations is often very hard due to the complexity and a huge data amount. In this article, I introduce several linear and non-linear tools, developed to analyze a huge time series data in many scientific researches, and apply them to EEG to characterize various sleep states. In particular, the spectral analysis, detrended fluctuation analysis (DFA), and synchrony analysis are administered to EEG recorded during nocturnal polysomnography (NPSG) processes and daytime multiple sleep latency tests (MSLT). I report that 1) sleep stages could be differentiated by the spectral analysis and the DFA ; 2) the gradual transition from Wake to Sleep during the sleep onset could be illustrated by the spectral analysis and the DFA ; 3) electrophysiological properties of narcolepsy could be characterized by the DFA ; 4) hypnic jerks (sleep starts) could be quantified by the synchrony analysis.

The purpose of this study was to identify the sleep/activity patterns of neonates and to provide a baseline data for the development effective mother-infant relationship. Subjects of this study were 36 newborns aged 1-21 days and stayed in Postpartum Care Center in Taejon during the period of October 28th, 1999 to February 10th, 2000. The data were collected using NCASA developed by Barnard et al. and were analyzed with SPSS 7.5 for window program. The results of this study were as follows: 1. An average day sleep of neonates was 8.0 hours, night sleep was 3.6 hours, and total sleep was 11.6 hours. A longest period of day sleep was 3.8 hours and a longest period of night sleep was 3.4 hours. The regularity of day sleep was 22.1%, night sleep was 23.3%, and total was 22.1%. 2. The frequency of daytime feeding was 6.9, nighttime fee ding was 3.4, resulting in total of 10.3. The regularity of feeding was 37.4%, and the frequency of night awakening was 2.4. 3. Associations among variables related to neonate's sleep/activity records were as follows : - The regularity of total sleep was positively correlated with the frequencies of day sleep(r=.57, P=.00), night sleep (r=.40, P=.01), and total sleep(r=.65, P=.00). - The frequency of total feeding was negatively correlated with the frequencies of day sleep(r=-.29, P=.04), night sleep(r=-.39, P=.02), and total sleep(r=-.42, P=.00), as well as longest day sleep(r=-.50, P=.00). - The regularity of feeding was negatively correlated with the frequency of night sleep(r=-.35, P=.02), longest period of day sleep(r=-.32, P=.04), and longest period of night sleep(r=-.30. P=.04), whereas positively correlated with frequencies of daytime feeding (r=.29, P=.02) and nighttime feeding (r=.32, P=.05). - The frequency of night awakening was negatively correlated with amount of night sleep(r=-.39, P=.02) and frequency of daytime feeding(r=-.42, P=.01) while positively correlated with frequencies of nighttime feeding(r=.68, P=.00) and total feeding(r=.50, P=.00). 4. Although there was no statistical significant difference between sleep pattern and infant's age, following tendency was noted: - As baby gets older, total amount of sleep and longest period of day sleep decreased while longest period of night sleep increased. - As baby gets older, the regularity of day sleep decreased while the regularity of night sleep and total sleep slightly increased. - The frequencies of daytime and total feedings increased while the frequency of nighttime feeding decreased. In conclusion, the author found that the neonates of this study showed less amount of sleep, more night awakening, and more night time feedings than NCAST sample. There was a certain sleep/activity pattern existed: If babies were fed more frequently, daytime or nighttime sleeping hours became shorter, and if babies had longer daytime sleep, frequent nighttime awakenings were noted. This pattern illustrated the significant influence of feeding and sleep periods on each other. Awakening in the night is natural and normal patterns in the newborn period. The result of this study will provide information to parents about what to expect their infants.

Purpose : The purpose of this study was to identify the degree of occupational therapist's sleep quality and examine the correlation between sleep quality and job stress. We also investigated the effects of the occupational therapist's sleep quality on job stress. Therefore, we aimed to investigate the importance of sleep quality and find a way to reduce job stress in occupational therapists. Methods : We conducted a study from November 7 to from December 23, 2022. To assess sleep quality and job stress, sleep quality of scale and Korean occupational stress scale-SF (KOSS-SF) were used. The general characteristics, sleep quality, job stress were examined using a frequency analysis and presented with descriptive statistics. The pearson correlation coefficient was used to determine, whether there was a correlation between sleep quality and job stress. To find what factors have and effect on job stress, we conducted a multiple regression analysis. A significance level of α=.05 was used to verify statistical significance. Results : First, average sleep quality score was 2.10±.19. Second, a significant correlation was found between sleep quality and job stress (p<.01). And As a result of the relationship between sleep quality sub-factors and job stress, day time dysfunction (r=.23, p<.01), restoration (r=.18, p<.05), difficulty of falling asleep (r=.38, p<.01). difficulty of awakening (r=.36, p<.01), satisfaction (r=.33, p<.01) and difficulty of maintaining sleep (r=.24, p<.05) showed a statistically significant relationship with job stress. Third, the sub-factors of sleep quality influencing job stress were difficulty of falling asleep (β =.26, p<.01), difficulty of awakening (β=.23, p<.01) and satisfaction (β=.21, p<.01). Conclusion : The results of this study, demonstrated the importance of sleep quality in affecting job stress. Therefore, follow-up studies are, necessary to develop interventions to improve, occupational therapist's sleep quality in the future.

연구배경 : 수면다원기록에 따르는 첫날밤 효과가 수면연구자들 사이에서 널리 알려진 개념임에도 불구하고 이에 대한 국내 연구가 전무한 형편이고 한편으로는 이제까지의 연구결과들의 일관성이 없어 우선 건강한 젊은 성인을 대상으로 첫날밤 효과에 관해 연구 하고자 하였다. 방법 : 남자 의과대학생 8 명을 대상으로 2 일간의 야간수면 다원기록을 실시하여 산출된 수면 변인들에 대 하여 첫째 날과 둘째 날의 결과를 비교 분석하였다. 결과 : 양 일간의 유의한 차이는 첫날밤에 수면기간 시간과 취침시간을 3 등분한 후반 1/3의 총수면 시간이 증가한 소견이었다. 그 외 제반 변인에서는 유의한 차이를 발견할 수 없었다. 결론 : 본 연구에서 첫날밤 효과를 확인할 수 없었던 것은 1) 피험자들의 나이가 젊어 적응력이 뛰어났고, 2) 검사실 환경이 비교적 쾌적하여 집의 침실과 같은 안락한 환경을 제공하였기 때문으로 생각된다. 피험자의 연령과 수면 검사환경을 고려하지 않고 첫날밤 효과를 배제하기 위해서 무조건적으로 첫날밤의 수면다원기록 자료를 경시 또는 제외할 필요는 없다고 판단된다.

Sleep apnea syndrome is a common clinical disorder characterized by intermittent cessation of airflow at nose and mouth during sleep. The clinical significance of this syndrome is that it is one of the most common causes of excessive daytime sleepiness. It can also cause neuropsychiatric, cardiovascular, and cerebrovascular complications. The standard for diagnosis of sleep apnea syndrome is nocturnal polysomnography. Because polysomnography is a time-consuming and expensive test, many efforts have been made to replace polysomnography with a simpler system of monitoring, but no method has yet been approved as a definitive investigation method. The goals of treatment for this syndrome are to eliminate excessive daytime sleepiness and to reduce the risk of possible cardiovascular complications. Continuous positive airway pressure is the most definite and widely accepted treatment for achieving these goals. Other treatments such as surgical treatment, oral appliances, and behavioral therapy may be useful for selected patients who are mildly affected.

Background: Sleep-related disturbances and sleep disorders are common in Parkinson's disease (PD) and have a great impact on daily life of PD patients. This study was done to find the sleep characteristics and sleep disturbing factors in PD patients according to disease severity through clinical interview and polysomnographic (PSG) study. Methods: Fifty patients with PD (22 males, age $60.6{\pm}6.4$, Hoehn and Yahr (HY) stage $2.7{\pm}1.0$) were recruited and thoroughly interviewed about their sleep. PSG was performed on the patients taking routine antiparkinsonian medications. Patients were grouped into mild and moderate/severe group according to HY stage, and the results were compared between each group. Results: Ninety-four percent of total patients had one or more sleep-related disturbances based on the interview or PSG. On interview, the moderate/severe group complained more insomnia and REM sleep behavior disorder (RBD) than mild group. In PSG findings, the moderate/severe group showed lower sleep efficiency, longer sleep latency, REM sleep latency, waking time after sleep onset, and higher prevalence of RBD. Conclusions: In this study, most patients with PD had sleep disturbances. Clinical interview and PSG findings revealed deterioration of sleep quality along the disease severity. Our results suggest that sleep disturbances in PD patients are prevalent and warrant clinical attention, especially to the patients with advanced disease.
