Purpose: The purpose of this study was to measure the fatigue of operating room nurses and examine factors contributing to their fatigue. Methods: The subjects of this study were 115 nurses who worked in operating rooms of three hospitals. Data were collected from September 15, 2009 to September 30, 2009. Fatigue and job stress were measured by using the Symptom's Fatigue Scale and the job stress measurement tools in operating room nurses. Results: The mean score of fatigue level was $3.10{\pm}0.61$. We analyzed fatigue according to characteristics of subjects and found that there were significant differences in marital status, number of children and sleeping hours in general characteristics. Career, daily participation hours in the surgery relating to job related characteristics. Significant positive correlations were found between job stress and fatigue(r=.233, p= .012). Three significant variables influencing fatigue of operation rooms nurses were job stress, daily participation hours in the surgery, and sleeping hours (Adj. $R^2$=0.284, F=4.773, p<.001). Conclusion: An integrative care program that takes job stress, daily participation hours in the surgery and sleeping hours into consideration is essential to reduce fatigue in operating room nurses.

Purpose: Saturday night palsy is a transient form of nerve palsy that occurs after a prolonged period of direct pressure on the course of radial nerve by one's own or spouse's head. Although commonly encountered, there have been only few studies concerning its convalescence. The purpose of this study is to predict the prognosis of Saturday night palsy based on the causes, time to recovery and degree of recovery. Materials and Methods: Retrospective study of 20 patients who were diagnosed compression radial nerve palsy was performed. The average age was 36.7 years old and the mean follow-up period was 19.6 months. We investigated sleeping hours as an indirect measure of nerve compression time, recovery of wrist and finger extension, DASH score on the monthly based follow up. Results: The mean sleeping hours was 5.8 hours and all patients showed full recovery of wrist and fingers extension with the mean duration of symptom for 3.2 months. DASH score was an average 1.53 at the last follow up and we found no statistical significance between the time to recovery and the sleeping hours. Conclusion: Complete natural recovery can be expected in compression radial nerve palsy in this study without correlation with sleeping time. Accurate diagnosis is important in order to avoid unnecessary therapeutic intervention and further study should be accomplished for clarifying the related prognostic factors in larger scale of the cases.

Purpose: This study was carried out to investigate the prevalence and the main factors influencing the farmer's Syndrome in farmers in Korea. Method: A survey questionnaire was completed by 238 farmers who lived in 8 agricultural districts in Seosan City. The data were collected from April 10 to May 5, 2002. Results: The prevalence of the farmer's Syndrome was 42.6%, and its prevalence rate in woman was higher than that in man. The prevalence of the farmers syndrome proportionally increased with advanced age. Variables that were positively correlated with the farmer's syndrome were age, duration of farming, days of resting, and the number of the agricultural chemical's poisoning. On the other hand, variables that were negatively correlated with the farmers syndrome were smoking, sleeping hours, economic condition, and level of educational. In a regression analysis, the factors influencing the farmers syndrome were age, sex, sleeping hours, days of resting, and the number of the agricultural chemical's poisoning, which accounted for 25% of the total variance. Conclusion: Based on these study results, older age and woman gender are the remarkable risk factors influencing the farmer's syndrome. Sleeping hours, days of resting, and the number of the agricultural chemical's poisoning were also the significant attributable variables to the farmers syndrome.

Objectives : In this study, we investigated the correlation of mental-and oral-health status with periodontal disease. Ultimately, we sought to make a positive contribution to the promotion of periodontal health and the prevention of periodontal disease. Methods : This study was analyzed using the data of KNHANES 2013-2015. The participants of this study were between 20 and 64 years old. The final selection was 1,512 adults. Results : Participants with a sleeping time of less than 6 hours and those who recognized stress showed higher periodontal disease. Number of decaying teeth, oral-health status, toothaches, and chewing problems were associated significantly with periodontal disease. To investigate the effects of general characteristics and mental and oral-health status on periodontal disease, a logistic regression analysis was conducted. Sex, age, education level, smoking status, oral-health status, and chewing problems were variables that affected periodontal disease. Conclusions : This study showed that mental-and oral-health status is closely related to periodontal disease. Therefore, it is expected that this will be used as basic data to effectively improve periodontal disease in adults.

Daily use characteristics of apparent power supplied to distribution transformer can be separated into two different time zone of waking hours and sleeping hours. In sleeping hours, using amount of power is decreasing. The actual curve of power seemed to be quite similar to this kind of separation. Inserting a condenser into a circuit in each different time zone led to maximize power factor of the transformer. The compensating condenser's on/off time is controlled by hysteresis circuit utilizing op amp and power factor of the transformer was improved from 0.945 to 0.999. As a result, the average of current reduction was 2.53A per hour of transformer.

It is said that the chinese medicine, Ginseng root has some effects on the central nervous system . Ginseng saponin was prepared from Ginseng methanol extract and its effect on general behavioral activity was studied in rats. Each experimental group was composed of 8 rats. The behavioral activity of rats was observed in terms of 7 components i.e. sleeping, lying, grooming, rearing, walking, eating and drinking. In each group, total duration of behavior-observation was 2 hours, which were devided into four 30 min-intervals. The behavior-observation was done 10 times for each interval, so total number of observation was 40 times throughout 2 hours. Ginseng sapoain showed central nervous system stimulant action in reduced sleeping component and in increased activity components. From the results of this study, it is suggested that Ginseng saponin inhibits the extrapyramidal action of chlorpromazine.
