Mankind spends a third of it's lifetime sleeping. Sleep deficiency can cause several psychological and physical complications - as well as death - if prolonged over extended periods. Therefore, sleep is a substantial part of life and essential to the preservation of human-life. In modern society, human-beings are having more difficulty with sleep than ever before. Consequently, the need for medical research on sleep has increased as well. There are no studies in current western medicine that focuses entirely on sleep alone. However, there have been ongoing research by traditional eastern medicine on sleep and sleep-related-dysfunctions since ancient times which has yielded diverse results. Undertaken a study of the sleep and sleep-related-dysfunction in traditional medicine of East-asia, I have summarized my studies into the following. 1. From ancient china to the age of the warring state(戰國時代) - ground on few data that we can get - humans have a simple and rough cognizance of sleep and sleep-related- dysfunction. But people are little removed from shamanism yet. 2. After Han(漢) dynasty, in "Huang Di Nei Jing(黃帝內經)" and "Shang Han Lun(傷寒論)" and "Jin Gui Yao Lue(金匱要略)", people present a basic physiology and pathology of sleep. 3. The theory has improved repeatedly in quality and quantity through "Zhen Jiu Jia Yi Jing(針灸甲乙經)" of Huang Fu Mi(皇甫謐) of Jin(晉) dynasty, "Bei Ji Qian Jin Yao Fang(備急千金要方)" of Sun Si Miao(孫思邈) of Tang(唐) dynasty to "Tai Ping Sheng Hui Fang(太平聖惠方)" of Song(宋) dynasty.

1. In Sui, Tang and Five Dynasty, a discourse related to sleep was published in various big Fang Shu(方書)'s that later became a valuable historical data. Notably, the importance of good sleep began to be properly discussed in "Bei Ji Qian Jin Yao Fang(備急千金要方)" of 'Sun Si Miao(孫思邈)', etc. 2. During Two Song era, achievements in the previous eras were accepted and diseases related to sleep were explored in more details. 3. In Jin and Yuan(金元) era, Liu He Jian(劉河間), in "Su Wen Xuan Ji Yuan Bing Shi(素問玄機原病式)", recognized 'anger' as the cause for various sleep disorders and Li Dong Yuan(李東垣), in "Pi Wei Lun(脾胃論)", believed 'lethargy' and 'Shi Hou Ji Hun Mao Yu Shui(食後卽昏冒欲睡)' are related to narcolepsy linked with stomach. Zhang Cong Zheng(張從正) observed 'insomnia' as an isolated disease whereas Zhu Dan Xi(朱丹溪), in "Ge Zhi Yu Lun(格致餘論)" argued about somnambulism based on the relationship between Xiang Huo(相火) and Xin huo(心火).

Purpose: This study aimed to explore the subjective sleep quality of depressed and non-depressed mothers in the late postpartum period and to determine the relationship with their health promoting behaviors, family functioning, parenting stress. Method: A non-probability sample of 128 mothers completed a self-administered questionnaires at 4-6weeks postpartum. The Edinburgh postnatal Depression Scale (EPDS) and Pittsburgh Sleep Quality Index were used to measure mother's experiences of depression symptoms and sleep. Related factors of sleep quality were measured by the Korean Family Functioning Scale, Health Promoting Lifestyle Profile, and Parenting Stress Index. The data was analysed using t-test, one-way ANOVA, and the Pearson's correlation coefficients. Result: The results indicated that the depressed mothers (EPDS$\geq$ 10) had poorer sleep quality than the non-depressed mothers(EPDS < 10), reported shortened sleep duration, and experienced more daytime dysfunctions. Depressed mothers who had no job, did not drink coffee, and were primipara tended to report poorer sleep quality. There were significant correlation between poorer sleep quality and lower health promoting behaviors, higher family intimacy and lower family communication, and higher parenting stress among depressed mothers. Conclusion: Our findings support the view that depressed mothers' experiences of poor sleep are much higher than non-depressed mothers and multi-faced. Nurse professionals should screen for sleep problems in the depressed mothers with a different biopsychosocial and behavioral aspect from the non-depressed mothers in the late postpartum period.

Insomnia is a common sleep-related symptom which occurs in many populations, however, the neural mechanism underlying insomnia is not yet known. The hyperarousal model explains the neural mechanism of insomnia to some extent, and the frontal cortex dysfunction has been known to be related to primary insomnia. In this review, we discuss studies that applied resting state and/or task-related functional magnetic resonance imaging to demonstrate the deficits/dysfunctions of functional activation and network in primary insomnia. Empirical evidence of the hyperarousal model and proposed relation between the frontal cortex and other brain regions in primary insomnia are examined. Reviewing these studies could provide critical insights regarding the pathophysiology, brain network and cerebral activation in insomnia and the development of novel methodologies for the diagnosis and treatment of insomnia.

Objectives: Bipolar disorder is characterized by repetitive relapses that result in psychosocial dysfunctions. The functioning of bipolar disorder patients is related to the severity of symptoms, quality of sleep, drug compliance, and social support. The purpose of this study was to investigate the association between sociodemographic and clinical factors and functional status in bipolar disorder patients. Methods: A total of 52 bipolar disorder patients participated in the study. The following scales were utilized: Korean version of personal and social performance scale (K-PSP), Korean version of Hamilton rating scale for depression (K-HDRS), Korean version of young mania rating scale (K-YMRS), Korean version of pittsburgh sleep quality index (PSQI-K), Korean version of drug attitude inventory (K-DAI), mood disorders insight scale (MDIS), and multidimensional scale of perceived social support (MSPSS). Results: The K-PSP score showed a negative relationship with K-HDRS score (r = -0.387, p = 0.005), but not with K-YMRS score (r = -0.205, p = 0.145). The K-PSP score showed a negative relationship with global PSQI-K score (r = -0.378, p = 0.005) and overall sleep quality (r = -0.353, p = 0.010). The K-PSP scores were positively associated with the KDAI score (r = 0.409, p = 0.003) and MSPSS score (r = 0.334, p = 0.015). The predictive factors for K-PSP were overall sleep quality and social support from family. Conclusion: Our study showed that depressive symptoms were related to overall function in bipolar disorder. Also, our study suggested that improving sleep quality is important in maintaining functional status. Appropriate social support and positive perception toward the drug may lead to the higher level of functioning. This study is meaningful in that the functional status of bipolar disorder patients is analyzed in a multivariate manner in relation to various variables in psychosocial aspects.
