Purpose : There are two types of sleep disturbance: inability to sleep (不眠) and somnolence (多眠). This study is to examine treatments of the two types of sleep disturbance in the Books of Cold Damage and how those theories were established and formed. Methods : 1. Verses including the words related to inability to sleep and somnolence were extracted from "Treatise on Cold Damage Diseases" (傷寒論). 2. Among the Books on Cold Damages that are classified according to the symptoms, 17 books with contents related to inability to sleep and somnolence were selected to collect and classify data in three perspectives: mechanism of disease (病機), method of treatment (治法) and disease pattern (病證). 3. Data collected through the above methods were compared and diagramed. Results & Conclusions : 1. On Cold Damage, inability to sleep is mostly rooted when human body lacks yin energy while having excessive yang energy (陽盛陰虛) due to fire and heat (火熱). The reason could be misuse of perspiration inducing method (汗法) or purgation (下法) on the doctors' part. 2. On Cold Damage, somnolence is rooted when pathogen (邪氣) is spread to yin meridians (陰經) and the human body lacks yang while having excessive yin energy (陰盛陽虛) or when heat (熱邪) is invaded into interior parts (裏部). 3. Many scholars of Cold Damage in later periods had copied the "Treatise on Cold Damage Diseases" for treatments of sleep disturbance but many others have applied the verses from "Treatise on Cold Damage Diseases" or added new treatments. Do jeol-am (陶節庵) and Wang Geung-dang (王肯堂) particularly had deep understanding on "Treatise on Cold Damage Diseases" and utilized the content freely or suggested new remedies because they had thorough knowledge on relating formula as well.

Sleep disorders are very common among pediatric patients. Its prevalence is between 10% and 45% in preschool- and school-aged children. However parents commonly do not concern about their children's sleeping habits and for many pediatricians, there is not part of the routine office visit about a childs sleep. Sleep disorders were classified by International Classification of Sleep Disorder (ICSD) as dyssomnias, parasomnias, sleep disorders associated with mental, neurologic, or other medical disorders, and proposed sleep disorders. There are lots of differences in the causes, manifestations, and managements of sleep disorders between children and adult. The sleep disorders in childhood may manifest themselves as bedtime resistance, refusal to go to bed at a parentally described time, sleep-onset delay, inability to fall asleep within a reasonable time, prolonged nighttime awakening, and inability to return to sleep without assistance after waking during the night, and so have wide-ranging influences on children's behavior, mood, school performance, and family life. It's very important for pediatrician to concern about the sleep disturbances in childhood and so the problems of sleep in children should be early detected and managed.

In order to investigate the effects of rotating shift work on the subjective characteristics of sleep and mental depression questionnaire survey was carried out on 405 shift workers and 153 nonshift workers who were nurses employed. in three university hospital. The questionnaire forms used in this study were the self rating depression scale(SDS) and circadian type questionnaire(CTQ) factor R(rigidity/flexbility of sleeping habit) and factor V(inability/ability to overcome drowsiness). The results were as follows ; 1. Mean score of CTQ R in shift workers was significantly lower than that in nonshift workers, however, no significant difference in CTQ V was observed between two groups. 2. Mean score of SDS was significantly higher in shift workers(44.1) than in nonshift workers(39.8). 3. Mean self rating depression scale scores of pervasive affect, physiologic equivalents and psychological equivalents were significantly higher in shift workers than in nonshift workers. 4. In shift worker, mean SDS score was the highest in confusion and followed by diurnal variation, retardation, and indeciveness in the descending order. In nonshift worker, that score was the highest in decreased libido and followed by confusion, and indeciveness in the descending order. 5. Circadian type questionnaire scores was significantly and negatively correlated with significantly and negatively correlating with Self-rating depression scale scores(r=-0.473).

Acute respiratory distress syndrome (ARDS) is a common cause of severe hypoxemia defined by the acute onset of bilateral non-cardiogenic pulmonary edema. The diagnosis is made by defined consensus criteria. Supportive care, including prevention of further injury to the lungs, is the only treatment that conclusively improves outcomes. The inability to find more advanced therapies is due, in part, to the highly sensitive but relatively non-specific current syndromic consensus criteria, combining a heterogenous population of patients under the umbrella of ARDS. With few effective therapies, the morality rate remains 30% to 40%. Many subphenotypes of ARDS have been proposed to cluster patients with shared combinations of observable or measurable traits. Subphenotyping patients is a strategy to overcome heterogeneity to advance clinical research and eventually identify treatable traits. Subphenotypes of ARDS have been proposed based on radiographic patterns, protein biomarkers, transcriptomics, and/or machine-based clustering of clinical and biological variables. Some of these strategies have been reproducible across patient cohorts, but at present all have practical limitations to their implementation. Furthermore, there is no agreement on which strategy is the most appropriate. This review will discuss the current strategies for subphenotyping patients with ARDS, including the strengths and limitations, and the future directions of ARDS subphenotyping.

Objectives: The present study is carried out to review the efficacy of Korean, Oriental medicine on premenstrual syndrome. Methods: We searched for 7 internet worldwide databases in order to find the studies with the keywords of 'premenstrual syndrome', 'premenstrual syndrome & Oriental medicine', 'premenstrual syndrome & traditional Chinese medicine' and 'premenstrual syndrome & herbal medicine' from 2009 to 2019. after selecting studies based on own criteria, total 8 studies are finally included. the studies were assessed with the Cochrane risk of bias criteria and reviewed systematically. Results: After intervention, cured patient rate in test groups in all of studies were significantly higher than rate in control group. there were significant decrease in headache, anorexia, dry mouth, breast mass, mastodynia, agitation, irascibility, edema, dizziness, fever, anhedonia, depression, inability to sleep, profuse dreaming with herbal medicinal intervention. 3 of those studies checked hormonal level. Estradiol (E2) and Progesteron (P) changed significantly in 2 of studies. Prolactin (PRL) in 1 study decreased significantly. FSH (Follicle stimulating hormone) and LH (Luteinizing hormone) had no significant decrease in 1 study. Conclusions: This review suggests that herbal medicine on premenstrual syndrome is effective without serious adverse effects. however, since unclear risk of bias, the result of this study should be considered carefully. further clinical trials should be carried out in order to academical clinical progress regarding treatment of premenstrual syndrome.
