The purpose of this study is to identify the effects of laughter therapy on depression and sleep wake disorders among the elderly in residential facilities using a systemic review and meta-analysis. Twelve databases were searched. Two researchers independently performed the selection of the studies, data coding and assessment. The risk of bias was assessed using risk of bias (RoB) and risk of bias assessment tool for non-randomized studies (RoBANs). To estimate the effect size, meta-analysis of the studies was performed using R version 4.04. Out of the 1,122 retrieved articles, one randomized controlled trial (RCT) and eleven non-randomized controlled trials (non-RCTs) were selected for analysis. The overall effect size of eleven studies on depression was determined to be -1.04 (95% Cl: -1.53~-0.54, p<.001). There were statistically significant in the effect of below ten sessions and the effect of below 400 minutes'and 400 to 1000 minutes'interventions on depression. The overall effect size of five studies on sleep wake disorders was 0.83 (95% Cl: -0.26~1.93, p=.136), which was not statistically significant. There was statistically significant in the effect of below 300 minutes'interventions on sleep wake disorders. Laughter therapy was an effective non-pharmacological intervention to reduce depression among the elderly in residential facilities. The findings also suggest that guidelines for laughter therapy need to be developed considering the number of sessions and a duration of intervention to reduce depression and sleep wake disorders of the elderly in residential facilities.

Background and Objectives: Obstructive sleep apnea (OSA) is often undiagnosed but is an important risk factor affecting the health of an individual. The level of awareness of the illness among patients with OSA is low and is not correlated with severity of the illness. This study was conducted to compare awareness of OSA symptoms and illness between patients with OSA and simple snorers. Materials and Methods: Two hundred eighty-two patients who were suspected of having OSA participated in this study. All subjects underwent overnight polysomnography. Those with an apnea-hypopnea index (AHI) ${\geq}5$ were classified as the OSA group, while those with an AHI < 5 were classified as the simple snoring group. A sleep questionnaire, which included items on awareness of the illness, OSA, and sleep symptoms, was administered to all subjects and their bed-partners. Results: Simple snorers were much more aware of their symptoms such as snoring, irregular breathing, and apnea than were patients with OSA. Bed-partners of simple snorers were also more aware of the participants' sleep symptoms than were partners of patients with OSA. However, the duration of OSA symptoms was longer in the OSA group. In the correlation analysis, the level of awareness of OSA symptoms was negatively correlated with AHI, age, body mass index, and Epworth Sleepiness Scale score. Among the sleep questionnaire and polysomnography results, only Pittsburgh Sleep Quality Index was positively correlated with level of awareness of OSA symptoms. The minority of the respondents had heard about the treatment methods of continuous positive airway pressure and oral appliance and preferred them as treatment options. Conclusion: This study suggests that simple snorers are more aware of their symptoms than are patients with OSA. A higher severity of OSA, represented by a higher AHI, is correlated with lower awareness of one's OSA symptoms.

Background: The existing data indicate that obstructive sleep apnea syndrome contributes to the development of cardiovascular dysfunction such as systemic hypertension and cardiac arrhythmias, and the cardiovascular dysfunction has a major effect on high long-term mortality rate in obstructive sleep apnea syndrome patients. To a large extent the various studies have helped to clarify the pathophysiology of obstructive sleep apnea, but many basic questions still remain unanswered. Methods: In this study, the influence of obstructive sleep apnea on systemic blood pressure, cardiac rhythm and urinary catecholamines concentration was evaluated. Over-night polysomnography, 24-hour ambulatory blood pressure and ECG monitoring, and measurement of urinary catecholamines, norepinephrine (UNE) and epinephrine (UEP), during waking and sleep were undertaken in obstructive sleep apnea syndrome patients group (OSAS, n=29) and control group (Control, n=25). Results: 1) In OSAS and Control, UNE and UEP concentrations during sleep were significantly lower than during waking (P<0.01). In UNE concentrations during sleep, OSAS showed higher levels compare to Control (P<0.05). 2) In OSAS, there was a increasing tendency of the number of non-dipper of nocturnal blood pressure compare to Control (P=0.089). 3) In both group (n=54), mean systolic blood pressure during waking and sleep showed significant correlation with polysomnographic data including apnea index (AI), apnea-hypopnea index (AHI), arterial oxygen saturation nadir ($SaO_2$ nadir) and degree of oxygen desaturation (DOD). And UNE concentrations during sleep were correlated with AI, AHI, $SaO_2$ nadir, DOD and mean diastolic blood pressure during sleep. 4) In OSAS with AI>20 (n==14), there was a significant difference of heart rates before, during and after apneic events (P<0.01), and these changes of heart rates were correlated with the duration of apnea (P<0.01). The difference of heart rates between apneic and postapneic period (${\Delta}HR$) was significantly correlated with the difference of arterial oxygen saturation between before and after apneic event (${\Delta}SaO_2$) (r=0.223, P<0.001). 5) There was no significant difference in the incidence of cardiac arrhythmias between OSAS and Control In Control, the incidence of ventricular ectopy during sleep was significantly lower than during waking. But in OSAS, there was no difference between during waking and sleep. Conclusion : These results suggested that recurrent hypoxia and arousals from sleep in patients with obstructive sleep apnea syndrome may increase sympathetic nervous system activity, and recurrent hypoxia and increased sympathetic nervous system activity could contribute to the development of cardiovascular dysfunction including the changes of systemic blood pressure and cardiac function.

Purpose: Short sleep duration is associated with obesity. Urinary 6-sulfatoxymelatonin (6-OHMS), the principal metabolite of melatonin, is closely related with sleep. We evaluated the difference in urinary 6-OHMS levels between obese girls and normal weight girls, and the relationship of urinary 6-OHMS with other hormones regulating body weight and metabolism. Methods: A total of 79 girls (6.3 to 12.4 years) were included in this study, of whom 34 were obese; 15, overweight; and 30, normal-weight. We examined their pubertal status and bone age. Fasting serum levels of total ghrelin, leptin, insulin, and first morning urinary 6-OHMS were measured. Homeostatic model assessment-insulin resistance (HOMA-IR) was calculated from the fasting insulin and glucose levels. Results: There was no significant difference in the creatinine adjusted 6-OHMS levels between the obese girls and the control group. Urinary 6-OHMS did not show any correlations with body mass index (BMI), BMI percentile, total ghrelin, leptin, and HOMA-IR. Negative correlations were found between urinary 6-OHMS levels and chronological and bone ages. Conclusion: Our results suggest that melatonin production is not reduced consistently in obese girls.

Objectives Generally speaking, we could've not been used moxibustion to Soyangin. But we thought what matters is that which point is chosen, not that what method is chosen. So we had a case of moxibustion at Ki1 for a Soyangin patient with insomnia Methods We managed a patient with insomnia after intracranial hemorrhage. He had been undergone conservative therapy, herb medicine, acupuncture, sedatives. 20 days after admission we started to do moxibustion at both Ki 1 point(湧泉). We used artemisia and, the method was direct form. Results The duration and the quality of sleep of the patient was improved. After 10 days, he could sleep for 5 hours. Accompanied symptoms, as mentality, urination, and defication, was also improved. Conclusions From this case we could accept the efficacy of moxibustion at Ki 1 for Soyangin patient suffering from insomnia.

This study focuses on users of activity tracking technologies and their related information behavior. How useful is the provided information by the trackers? Do users understand all information and explanations? We conducted a web-based survey. All in all, 631 users of a tracking device filled out the survey. From the perspective of information science, this investigation aims to analyze information needs considering different types of the provided information by activity tracking technologies. Are users satisfied by using the information on their steps, heart rates, and sleep duration? How do users assess readability about heart rate zones and sleep stages? Additionally, we investigated if users understand how to reflect on and adapt their health behavior based on the received explanations. According to the results, users mainly agree that the received information (raw data as well as - to a lesser extent - aggregated data in the form of corresponding diagrams) is useful, that the explanations are easy to understand, and that they know how to use this obtained information. This investigation enables an in-depth insight into how users are applying the self-quantifying activity and health information and which information needs are satisfied.

Purpose: This study was done to develop and examine the effects of a self-management program(SMP) on physical, psychological functions, and symptoms in patients with Parkinson's disease(PD). Methods: In a two-group pre-and post-test design, a total of 40 patients were assigned to the experimental group(21) or the control group (19). The experimental group received eight weekly 2-hour sessions for 10-15 literate adults of all ages, while the control group did not receive any intervention. Results: The experimental group showed significant improvements in muscle strength, balance, self-efficacy, depression, quality of life(QL), quality of sleep, and discomfort of constipation. It also reduced the number of participants using assistive walking devices. There were no significant changes in fear of falling and duration of sleep. Conclusion: The eight week SMP in patients with PD was found to be significantly effective in enhancing muscle strength, balance, self-efficacy, QL, and quality of sleep. It also decreased depression, discomfort of constipation, and assistive walking devices. These results suggest that a SMP can have effects on physical, psychological functions and symptoms in patients with PD. Further research with a larger sample and for a longer follow up period is needed to expand our understanding of the effects of a SMP for patients with PD.

Insomnia is one of the most common symtoms of Neuropsychiatry patients. These are many approaches to treat insomnia, but it is difficult to be resolved completely. Acupuncture and Auricular acupuncture have been used for relief insomnia. But it is not sufficient to compare the effect of Acupuncture treatment and Auricular acupuncture treatment. Thus we investigate the effect of Acupuncture treatment group and Auricular acupuncture treatment group. A clinical analysis was carried out for 40 patients who was treated insomnia with Acupuncture(20 patients) and Auricular acupuncture(20 patients) in Seoul Dong-Seo Oriental Hospital. 1. Total duration of sleeping time showed $1.55{\pm}1.1574$ hours increased in Acupuncture group and $0.925{\pm}1.184$ hours increased in Aricular acupuncture group. especially Acupuncture were much more effective method than Aricular acupuncture. P-value was 0.033 (P <0.05) 2. Delaying time before the onset of sleep showed $0.7375{\pm}0.8940$ hours decreased in Acupuncture group and $0.7969{\pm}1.3298$ hours decreased in Auricular acupuncture group. (P <0.05) 3. The wake times showed $0.9167{\pm}1.7299$ times decreased in Acupuncture group and $1.2308{\pm}1.1658$ times decreased in Auricular acupuncture group in sleep maintenance insomnia. (P <0.05) 4. Change in quality of sleep showed Excellent 30%, Good 50%, Fair 15%, Poor 5% in Acupuncture group and Excellent 20%, Good 45%, Fair 30%, Poor 5% in Aruricular acupuncture group.

Objectives : Since prostitution is multitraumatic phenomena, it is known that most women in prostitution have symptoms of posttraumatic stress disorder (PTSD) and other mental illness. In Korea, new anti-prostitution law launched in the year of 2004 imposes protecting prostituted victims at government-supported shelter. The objective of this study was to compare the mental symptoms, especially PTSD features of women who escaped from prostitution with those of control subjects. Methods : We assessed 113 ex-prostituted women who live in shelter for 8 months on the average and 65 normal control subjects. Demographic data, questionnaire for sleep, physical illness, smoking, alcohol and drug use, Stress Response Inventory, Davidson Trauma Scale (DTS), Impact of Event Scale-Revised (IES-R) were used. Results : Ex-prostituted women had significantly higher scores of DTS, IES-R, stress related responses, sleep problems, smoking problems, and alcohol problems than control group. Age and duration of sex trade of the subjects were significantly correlated with the severity or frequency of PTSD symptoms. The degree of smoking, alcohol drinking and sleep problems were also significantly correlated with the PTSD symptoms. Conclusion : These results suggested mental symptoms did not disappear even after women escaped from prostitution.

Purpose: To identify characteristics of chronic fatigue, difference between the duration of fatigue and characteristics of chronic fatigue, and association between chronic fatigue and related factors in adults. Method: The subjects for this study were 180 adults who had experienced fatigue for over one month The measurement tools were the Revised Fatigue Scale by Chalder et al. (1993), the Visual Analogue Scale-energy developed by Lee et al. (1991), the BEPSI (Brief Encounter Psychosocial Instrument) by Frank & Zyzanski (1988), Zung's self rating depression scale (1965) and life style items including exercise sleep, drinking smoking and diet as developed by the researchers. Results : Those who complained of fatigue over six months experienced higher disturbances in their daily life compared to those who had suffered from fatigue less than six months. There were a significant correlation between severity of fatigue and depression (r=.46, p<.001), stress (r=.41, p<.001), and sleep (r=.20, p<.01) Statistically significant relationships were found between severity of fatigue and amount of exercise per week (F=3.79. p<.05) disturbed sleep (t=-2.66, p<.01), number of times awakened during the night (F=3.48, p<.05) types of drinking (F=2.65, p<.05), and diet regularity (F=5.83, p<.01). The construction of a multiple regression model revealed an adjusted $R^2$ of .27 with the depression score serving the major predictor variables for severity of fatigue. Men and people in the younger age group were more energetic than women and those in other age groups. Also married people experienced more fatigue than people who were single. divorced or separated. Conclusion: In nursing interventions for fatigue, medical personnel should consider sociodemographic characteristics of the clients, ways to reduce of stress and counter disturbances in daily life and develop strategies for a health promoting life style.
