Insomnia has become a major public health issue in recent times. Although quality of sleep is affected by environmental, psychophysiological, and pharmacological factors, diet and nutrient intake also contribute to sleep problems. This study investigated the association between nutrient intake and co-morbid symptoms associated with sleep status among selected adults. Subjects in this study included 87 men and women aged 21-45 years. Presence of insomnia was assessed using the Insomnia Screening Questionnaire, and dietary intake was measured over three consecutive days by dietary survey. Descriptive analysis, ANOVA, and Chi-Square tests were performed to compute and interpret the data. Approximately 60% of the participants were insomniacs. People with insomnia consumed significantly lesser quantities of nutrients as compared to normal sleepers. Differences in intakes of energy, carbohydrates, folic acid, and $B_{12}$ were highly significant (P < 0.002). Further, intakes of protein, fat, and thiamine were significantly different (P < 0.021) between insomniacs and normal sleepers. The nutrient intake pattern of the insomniacs with co-morbid symptoms was quite different from that of the normal sleepers. Based on these results, it is probable that there is an association between nutrition deficiency, co-morbid symptoms, and sleep status. More studies are required to confirm these results.

Purpose : The objective of this study was to determine efficacy of sleep-dependent motor learning. Methods : This is a literature study with books and internet. We searched the PubMed, Science Direct, KISS and DBpia. Key words were Sleep-dependent, motor learning, RAM and LTP. Results : Procedural memory, like declarative memory, undergoes a slow, time-dependent period of consolidation. A process has recently been described wherein performance on some procedural task improves with the mere passage of time and has been termed "enhancement". Some studies have reported that the consolidation/enhancement of perceptual and motor skill is dependent on sleep. Specially, rapid-eye-movement(REM) sleep seems to benefit procedural aspects of memory. Conclusion : Motor learning is very important for CNS injury patients. And also distribution of practice sessions is important because REM sleep is to benefit procedural aspects of memory consolidation.

Purpose: Sleep onset association disorder (SOAD) is a form of behavioral insomnia observed in children that is caused by inappropriate sleep training. SOAD typically disturbs the sleep of not only infants and children but also their parents. We investigated levels of depression and marital intimacy among parents of infants with typical SOAD, to understand the influence of SOAD on family dynamics, as well as examine ways for improving depression and marital intimacy through behavioral training. Methods: Depression and marital intimacy were assessed using the Beck Depression Inventory (BDI) and Waring Intimacy Questionnaire (WIQ). These measures were administered to 65 parents of infants (n=50) diagnosed with SOAD. We conducted sleep education and behavioral training for the parents and compared levels of depression and marital intimacy after 2-6 weeks of training. Results: The 65 parents consisted of 50 mothers and 15 fathers. Depressive symptoms were higher among mothers than fathers (P=0.007). Marital intimacy was negatively correlated with depressive symptoms. Twenty-six parents were assessed again after sleep training. We found that mothers' depressive symptoms and marital intimacy improved post training. Conclusion: SOAD can be detrimental to both infants and parents, especially for parents who sleep with their infants. For instance, disruption of sleep patterns in such parents can reduce marital intimacy. However, behavioral modification is an effective treatment for infants with frequent nighttime waking, as well as for diminishing the depressive symptoms of sleep-deprived parents.

I try to understand the present state of sleep research in JON (The Journal of Oriental Neuropsychiatry) for the benefits of clinical practice. Methods : We searched and read every article on JON from 1990 to 2012 and selected ones that are related to Sleep Disorder; then analyzed the data to 5 categories, like literature study, case study, Clinical Data-Analysis study, experimental study, and clinical trial. Results : 1. We Found 41 articles relating to sleep disorder in JON form 1999 to 2012, and there were 9 literature studies, 13 case studies, 13 Clinical Data-Analysis studies, 4 experimental studies, and 2 clinical trials. 2. There were Sa-Am Acupuncture Method, Pharmacopuncture, electroacupuncture, and Auricular acupuncture to treat Sleep Disorder. 3. There were many additional treatments like Purgative Therapy, etc. 4. They reported the ordinary sleep pattern of Soeumin and Soyangin, too. 5. In the experimental study, they reported several herbs, herbal prescription on the expression of melatonin receptors, and Punsimgeimgamibang on insomnia, anxiety, emotionality in rats. 6. There were 2 clinical trials, one for Hwabyung-patient with insomnia by acupuncture treatment and another for insomnia in the elderly by ETF-I program. 7. There were 2 case of other sleep disorder (enuresis, sleepwalking) and 2 literature study of dream. Conclusions : In JON regarding sleep disorder, the majority was due to insomnia. Therefore, we also have to expand our sight into other sleep diseases. We need more clinical trials and experimental researches for the construction of EBM Sleep Disorder in Oriental Neuropsychiatry.

Sleep disturbance is a common health complaint affecting an estimated 10-25% of the general population. Pharmacotherapy is a traditional treatment and cognitive behavioral therapy is well demonstrated as an efficacious treatment for insomnia. There is a growing interest in the effectiveness of mindfulness meditation for sleep disturbed populations. Mindfulness involves focused, purposeful, nonjudgmental attention to a particular idea. In clinical application of mindfulness practice, mindfulness-based stress reduction and mindfulness-based cognitive therapy are used widely. Clinical trials support the effectiveness of meditation for the treatment of insomnia. The aim of this article is to review the effect of mindfulness meditation on insomnia.

Purpose: The purpose of this study was to examine the effects of aroma massage on pruritus, skin pH, skin hydration and sleep in elders in long-term care hospitals. Methods: The participants were elders over 65 years old admitted to long-term care. They were assigned to the experimental group (26) or control group (28). Data were collected from May to August, 2012. Visual Analogue Scale and Verran and Snyder-Halpern Sleep scale were used to identify levels of pruritus and sleep. A skin-pH meter and moisture checker were used to measure skin pH and skin hydration. Aroma massage was performed three times a week for 4 weeks for elders in the experimental group. The data were analyzed using the SPSS Win 17.0 program. Results: There were significant differences in pruritus, skin pH and skin hydration between the two groups. However there was no significant difference in sleep. Conclusion: The results indicate that aroma massage is effective in reducing pruritus, skin pH and increasing skin hydration in elders. Therefore, this intervention can be utilized in clinical practice as an effective nursing intervention to reduce pruritus in elders in long-term care hospitals.

The purpose of this study is to develop a meditation application to promote home practice in a meditation-based intervention program and test its effects. In most cases, meditation-based intervention programs put an emphasis on home practice, which means it is an important matter to increase motivation for home practice and encourage people to do home practice more. The investigator administered an eight-week Korean Mindfulness-based Stress Reduction (K-MBSR) program to college students participating in a liberal arts course at A University. While the experiment group (N = 22) received a meditation application, the comparison group (N = 19) received no meditation application. The amount of home practice was measured based on the practice logs kept by the participants. The difference in psychological effects between the groups was checked by measuring mindfulness, subfactors (noticing and return to body) of body awareness, life satisfaction, acceptance action, and sleep quality before and after the experiment. The findings show that the experiment group recorded significantly greater amounts of home practice than the comparison group. As for the effects of meditation, the experiment group recorded higher points in mindfulness, body awareness, life satisfaction, acceptance action, and sleep quality than the comparison group. These findings demonstrate that a meditation application can be useful as a means of assistance to promote the effects of a meditation-based intervention program. The study also discussed proposals for a follow-up study.

Objectives：Assessment of sleep disturbance is an essential part of the diagnostic criteria used for several psychiatric disorders. Change in sleep patterns over time may indicate response to treatment. In clinical practice, sleep is usually evaluated subjectively by patient self-report. This study was aimed to compare subjective sleep assessment with objective sleep measurement by actigraphy in psychiatric inpatients. Methods：A total of 32 psychiatric inpatients were studied. Patients were asked to wear a wrist actigraphy for three consecutive days and nights and to fill out a sleep log each morning. The severity of depression and anxiety was evaluated according to Beck Depression Inventory and State-Trait Anxiety Inventory on the first day of the study. The subjective level of satisfaction with quality of sleep was also evaluated according to visual analog scale. Nurses assessed sleep at one hour interval between 10:00 PM and 6:00 AM for three consecutive nights. Results：There was statistically significant difference of sleep latency between patient's sleep log and acti-graphic measurement. Nursing reports were more consistent with actigraphic measurement than sleep log. Interestingly, subjectively poor sleepers show no significant difference in sleep parameters compared with those of good sleepers. Subjectively poor sleepers report longer sleep latency than that of actigraphic assessment. The discrepancy between subjective and objective assessment of sleep latency was significantly correlated with scores of Beck Depression Inventory and State-Trait Anxiety Inventory. Conclusion：These results show that there are discrepancies between subjective and objective assessment of sleep. The discrepancy of sleep assessment could be influenced by severe depression and anxiety. Especially objective sleep measurement is needed to assess sleep in psychiatric inpatients with severe depression or anxiety and the subjectively poor sleepers for more reliable measurements.

This study was conducted to analyze the relationship between sleep quality, stress response, physical activity and sleep hygiene in shift work nurses and identify factors influencing sleep quality. The participants were 168 shift nurses from university hospitals and general hospitals located in C city, Gyeongnam. Data were collected from March 25 to 31, 2016. The study instrument use to the Pittsburgh Sleep Quality Index, Stress Response Inventory, Korean version of the International Physical Activity Questionnaire Short Form and Sleep Hygiene Scale. Date were analyzed by frequency, t-test, ANOVA, Pearson's correlation and hierarchical multiple regression using SPSS/win18.0. The sleep quality index was 7.35 (range 0-21), stress response was 2.20 (range 1-5), physical activity was 3986MET-min/week, and sleep hygiene was 2.73 (range 1-6 points). There were significant differences in sleep quality according to shift work experience, health status and circadian rhythm type. Factors influencing sleep quality included shift work experience, sleep hygiene, stress response and physical activity, which together explained 40% of the total variance of sleep quality. Therefore, it is recommended that sleep hygiene education be implemented as a strategy to reduce stress response, and that shift work nurses engage in a moderate level of physical activity to improve their sleep quality.
