Background: Poor sleep quality is associated with psychoactive substance abuse/addiction/withdrawal. Auricular acupuncture (AA) is a nonpharmacological method used for the treatment of sleep disturbances. This study aimed to examine the quality of sleep before and after AA in participants with mental and behavioral disorders due to prior multiple drug use in the therapeutic community. Methods: This was a consecutive case series of 27 participants (25 male [92.6%]). The median age was 35.0 years (interquartile range [IQR], 29.0-37.2 years), methadone/buprenorphine were not used, and the participants were treated with AA (median number of treatments, 15.0 [IQR, 12.0-18.0]) during a median period of 51.0 days (IQR, 49.0-51.0 days) according to the National Acupuncture Detoxification Association (NADA)-Acudetox protocol. Sleep quality was determined using the Pittsburgh Sleep Quality Index (PSQI), a self-rated questionnaire that assesses sleep quality and disturbances over a 1-month interval. Results: The global PSQI score dropped (indicating better sleep quality) by a median of 3.0 points (IQR, 0.0-8.0 points) after treatment. In the multivariate logistic regression analysis, with an increase in global PSQI score during AA by 1 point, there was a 0.73-fold reduction in the risk of poor sleep quality post-AA (adjusted odds ratio, 0.73; 95% confidence interval, 0.52-1.01; p<0.055; Nagelkerke's R² =0.66). Conclusion: The results revealed a positive effect of AA (by the NADA-Acudetox protocol) on sleep quality (as measured by PSQI) among participants in a treatment center with mental and behavioral disorders due to multiple drug use.

Although many studies have analyzed the relationship between electrodermal activity (EDA) and sleep stages, a practical method for detecting sleep stage using EDA has not been suggested. The aim of this study was to develop an algorithm for real-time automatic detection of deep sleep using the EDA signal. Simultaneously with overnight polysomnography (PSG), continuous measurement of skin conductance on the fingers was performed for ten subjects. The morphometric characteristics in the fluctuations of EDA signal were employed to establish the quantitative criteria for determining deep sleep. The 30-sec epoch-by-epoch comparison between the deep sleep detected by our method and that reported from PSG exhibited an average sensitivity of 74.6%, an average specificity of 98.0%, and an average accuracy of 96.1%. This study may address the growing need for a reliable and simple measure for identifying sleep stage without a PSG.

Purpose: The purpose of this study was to identify the effects of hand acupuncture therapy on sleep quality by means of a sleep questionnaire, polysomnography and a cerebral blood flow test in $30{\sim}59$ year old adults. Methods: The study was a sham controlled design. Twenty-two adults were assigned to the pellet stimulating group (11) or sham group (11). The pellet stimulating group received hand acupuncture therapy using New Seoam Press Pellets number 1 for 4 weeks. On the other hand, the sham group used the same Adhesive tape in terms of shape, size and quality as New Seoam Press Pellets number 1 for 4 weeks. A Transcranial Doppler Ultrasonography and Carotid Duplex Ultrasonography examination were used for evaluating cerebral blood flow. Data was analyzed using the SPSS 12.0 version program with $X^2-test$, Fisher's exact test and Mann Whitney U-test. Results: In the pellet stimulating group, subjective sleep quality significantly improved more than that of the sham group. Among the sleep indices of the polysomnography, total sleep time and sleep latency of the sham group significantly improved. The cerebral blood flow test didn't show any differences. Conclusion: These results suggest that hand acupuncture therapy is effective for subjective sleep improvement only, not polysomnographical sleep indices and cerebral blood flow.

Objectives: This study aims to identify the effect between high school students' recognition of mental health on sleep quality to present basic data for better health. Methods: The study used data obtained through the 2007 online research on adolescents' health behaviors, targeting a total of 35,228 high school students (18,628 of male students and 16,600 of female students). Results: Seventy six point ninety six percent of the male respondents and 79.67% of female respondents answered their sleep quality was not satisfactory. The subjects who had stress showed significantly lower quality of sleep than those who answered they had no stress. For female students, those who answered they had intention to suicide had significantly lower quality of sleep than those who answered they did not have, but for male students, there was no significant relations between them. There were no significant relations between sense of dispair and sleep quality both for male and female subjects. Conclusion: Factors of mental health related with sleep quality were stress and intention of suicide. The more they had stress and intention of suicide, the significantly lower sleep quality was. Therefore, in order to improve sleep quality of high school students, it is suggested that management programs based on education and counselling with experts should be provided and further studies on other mental health factors and sleep quality should be conducted.

Purpose: The purpose of this study was to compare the quality of sleep with the serum lipid profile in patients who have restless legs syndrome (RLS). Methods: The data were obtained from 116 patients with RLS through questionnaires and blood sampling. Results: The results of this study showed correlations between lower quality of sleep and serum lipid profile (LDL Cholesterol) in patients with RLS (r=.19, p=.040). There were correlations for scores of quality of sleep from the, Pittsburgh Sleep Quality Index (PSQI) sub-region between lower subjective sleep quality and serum lipid profile (LDL Cholesterol) (r=.20, p=.026), between fewer hours of sleep duration and serum lipid profile (Total Cholesterol) (r=-.21, p=.024), and, between higher daytime dysfunction and serum lipid profile (LDL Cholesterol) (r=.42, p<.001) of patients with RLS. Conclusion: Pati-ents with RLS have sleep disorders with lower quality of sleep and changes in the serum lipid profile for total cholesterol and LDL cholesterol. That is, patients with RLS have lower quality of sleep and dyslipidemia compared to persons without RLS. Further research is needed to monitor serum the lipid profile in early stage symptoms of midlife adult patients with RLS and especially older women.

In this study, OSA (the obstructive sleep apnea) periods were detected in patients with OSA during sleep because of the treatment was different according to the frequency and symptoms of obstructive sleep apnea. ANS (autonomic nervous activity) was changed by obstructive sleep apnea periods so we intended to detect the periods to care the obstructive sleep apnea patients. RR intervals, SDNN (standard deviation of normal to normal) and RMSSD (root mean square standard deviation) were calculated in time domain analysis and LF (low frequency), HF (high frequency), NHF (normalized high frequency), NLF (normalized low frequency) were calculated in frequency domain analysis of HRV (heart rate variability) with obstructive sleep apnea patients. In this paper, SDNN (standard deviation of normal to normal) of time domain analysis were decreased in the obstructive sleep apnea periods. And NLF and LF/HF ratio were increased and NHF (normalized high frequency) was decreased in the frequency domain analysis. The parameters can be used to treat obstructive sleep apnea patients by detecting the obstructive sleep apnea periods such as CPAP (continuous positive airway pressure).

Sleep is an essential biological process of which the underlying regulatory mechanisms involve numerous anatomical structures and biochemical substances that can be compromised by stress and the immune system. Gamma aminobutyric acid (GABA) is the main inhibitory neurotransmitter of the central nervous system (CNS). It is well established that activation of $GABA_A$ receptors promotes sleep. L. brevis BJ20 fermentation of sea tangle and oysters resulted in stress reduction and sleep inducing effects. This is the first study to report that GABA has the ability to induce sleep related hormones in mice; therefore, it has potential use as a natural sleep aid. These results suggested that sea tangle and oysters fermented by L. brevis BJ20 can be used as potential agents for stress reduction and sleep promotion.

Purpose: This study was conducted to identify the factors contributing to sleep disorders in patients on hemodialysis. Methods: A descriptive correlational study design was used. The participants were 135 patients on hemodialysis in hemodialysis clinics. Data were collected from March to May 2007 using structured questionnaires and hematologic sample. Stepwise multiple regression was used to identify factors influencing sleep disorders among the demographic-clinical factors, depression and fatigue. Results: About 69% of the patients had a sleep disorders. There were significant differences in sleep disorders according to marital status, caregiver, religion, economic level, insurance, erythropoietin, somnifacient, and antihypertensive agents. But there were no differences according to age, gender, dialysis period, or antidepressants. Their sleep disorders had significant correlations with depression, and fatigue, and a significant negative correlation with Protein, Albumin, Phosphate and BUN. But there were no correlations with hematocrit, hemoglobin, creatinine, sodium, potassium, or calcium. Depression and fatigue were factors influencing sleep disorders. They accounted for 43.8% of the variance in sleep disorders in these patients. Conclusion: Findings provide an understanding of sleep disorders and the factors that are an influence in patients on hemodialysis. To promote sleep in these patients, nursing interventions to manage depression and fatigue are needed.
