Background: Although cranial electrotherapy stimulation (CES) is reported to have positive effects on mental functions such as depression and sleep improvement, detailed studies regarding awakening, attention and concentration among brain waves reflecting brain activity are lacking. Objective: To examine the effects of cranial electrotherapy stimulation (CES) on various electroencephalograms (EEGs) reflecting brain activities. Design: Randomized controlled clinical trial (single blind) Methods: This study selected 30 healthy adult women in their 20s who volunteered for this experiment. A total of 30 subjects were randomly assigned to three groups (Sham group, 0.5 Hz CES group, and 100 Hz CES group). EEGs were measured before and after the single CES, and the results were compared and analyzed. Results: The relative theta, alpha, and gamma waves indicated no significant differences in the interaction effects between time and group. The relative fast alpha wave only showed significant differences in the interaction effects between time and group in P4. The relative slow beta wave only indicated statistically significant differences in the interaction effects between time and group in T3 and T4. The relative mid and fast beta waves showed statistically significant differences in the interaction effects between time and group in all areas. Conclusions: These results suggest that a CES of 0.5 Hz awakens consciousness and has a positive influence on brain activity, while a CES of 100 Hz has a positive influence on thinking activity accompanying mental load during concentrating on one subject.

This study was carried out to investigate the effects of intravenous drip with ketamine hydrochloride and its application for control depth and maintenance of anesthesia in dogs. Changes of blood pressure, vital signs, blood gas and anesthetic state were observed in this study. The obtained were summerized as follows ; 1. Changes of blood pressure and heart rate after intravenous drip anesthesia with ketamine hydrochloride were observed with significant increase in all group ; group II (0.135m81k9/min), group III (0.269mg/kg/min) and group IV(0.538mg/kg/min). These conditions were maintained unchangeably until 160 minutes after administration in all group. This may be indicated that there were no side effects on account of ketamine accumulation. 2. There were irregular respiration, pain reflex, Jaw tone reflex and vomition probability in the anesthetic conditions of group II The anesthetic conditions of group III were rarely shown as mentioned above. Awakening time and recovery time of group H were more prolonged 21 minutes and 27 minutes respectively than those of group III. These experimental data suggested that the optimal dosage of intravenous drip anesthesia of ketamine Hcl was 0.269mg/kg/min.

With the recent development of sleep medicine, insomnia has been perceived as a disease from a simple symptom. As there are various causes in a disease, proper treatment according to each cause is necessary for a more effective treatment In general, insomnia is classified into five categrories of physical, physiological, psychological, psychiatric and pharmacological aspects. However, such categorizations are often insufficient in treating insomnia. Furthermore understanding of the developmental mechanisms of insomnia is required. The function of sleep is developed and maintained through the balance of the reciprocal forces of sleep and arousal. These forces are contantly regulated by what is called a circadian rhythm. Sleep is induced by this rhythm which is affected by factors such as awakening time in the morning, amount of intellectual function, amount and time length of physical exercise and sunlight Insomnia could develop when this rhythm is delayed and leads to a "forbidden zone" which is a very difficult period for inducing sleep about two to four hours before the routine bedtime. Whereas sleep gradually develops in line with the circardian rhythm, arousal can occur very abruptly by any cause triggered by emotional discomfort or anxiety. Such characteristic and emotional factors as perfectionism, separation anxiety, secondary gain, insecurity, and negative cognition may provoke the inner anxiety and fear for insomnia, which can lead acute insomnia to a chronic one. As chronic insomnia is developed by multiple causes and factors, integrated approaches through analysis of above mentioned factors will be more effective in the treatment of insomnia than a simple administration of hypnotics.

Objectives : Zizyphus seed has long been used in hypnotics and sedatives in oriental medicine, and it is reported that the Zizyphus seed elicited a variety of pharmacological actions besides CNS depression. We did a clinical study on the effectiveness of Zizyphus seed (Ansim-san) for insomnia in stroke patients. Methods : To 41 stroke patients suffering from insomnia, we administered the extract of Zizyphus seed (Ansim-san). Outcome measures were subjective in nature and included a morning questionnaire, visual analog scales, and observation forms by study personnel. We also, to find the applicable symptom-complex of Zizyphus seed (Ansim-san), examined accompanying symptoms. Results : 1. Zizyphus seed extract use meant that sleep latency was shorter, total sleep time was longer, number of wakenings was lower, wake time during sleep was shorter, sleep quality was improved, condition upon awakening was improved, ability to concentrate was improved, and the patients fell asleep more easily (P<0.001). There were no differences in morning sleepiness. 2. Among accompanying symptoms, an oppressed feeling in the chest was significant (P=0.035) in the patients who improved sleep quality. Conclusions : The results of this clinical study suggest that in stroke patients, Zizyphus seed (Ansim-san) can be effective for insomnia, and significantly effective in patients who have an oppressed feeling in the chest.

Sleep is a necessity for survival. Disruption of sleep leads to numerous adverse physiological and psychological consequences. These could be particularly undesirable for older patients, who are subject to many additional factors. But there is limited research related to hospitalized elderly in Korea. The purpose of the study is to explore sleep patterns and disturbing factors of before and after hospitalization, in order to present basic information regarding elderly sleep to develop nursing intervention. The sample consisted of 32 elderly men and women between the ages of n and 87 years. Data collection was done from September to November 1997. Measures of sleep patterns and related factors were obtained from self-reported sleep questionnaires. Analysis of data was done by use of t-test, paired t-test, ANOVA, and Pearson Correlation Coefficient. The results of this study were summarized as follows : 1. In comparision between before and after admission of their sleep pattern, “sleep onset” tends to be delayed and nocturnal sleep time was significantly reduced. So, hospitalized elderly reported less total sleep time than before admission. 2. Regarding the sleep disturbing factors, medication(hypnotics ; 37.5%), physiological factor (snoring ; 59.4%) environmental factor (pillow ; 78.1%), emotional factor(anxiety related to disease ; 37.5%), and illness factor(fatigue ; 34.7%) were reported. 3. Significant differences in gender were found. Men had more disturbances in sleep than women owing to difficulty in falling a sleep and lack of nocturnal sleep. Women consumed more sleep inducing drugs. Significant increase was reported in napping during the day with increasing age. 4. Significant differences between good sleepers and poor sleepers were found for the following variables : nocturnal sleep time, total sleep time, bed time, sleep onset latency time, sleep latency time after nocturnal awakening, time spent in bed upon arousal, environmental factors, and emotional factors. In conclusion, it was found that the quantity and quality of sleep were significantly altered in hospitalized elderly, but adequate strategies for better sleep were not practiced. Further research is needed to develop Intervention strategies to promote sleep and to prevent sleep problems.

It is known that natural awakening of us in the morning is due to stimulation of the reticular activation system through biological clock in the suprachiasmatic nucleus of hypothalamus by the morning sunlight. If we sleep at dark rooms without windows and so without morning sunlight, thus, it is not easy fur us to get up refreshingly in the morning. In this paper, we propose an automatic sunrise household lighting system that helps us fer getting up cheerfully in the morning even if we sleep in dark rooms without morning sunlight. The proposed lighting system is an embedded system that turns automatically on the electric lamp and makes it brighter and brighter coincidently with the actual sunrise. The proposed system is composed of a PIC microcontroller with flash memory, a real-time clock IC, a D/A converter, an amplifier, a dimmer unit, a light bulb, a display panel and a keyboard. The validity of the proposed intelligent lighting system is demonstrated via a prototype production and experimentation.

Obstructive sleep apnea syndrome (OSAS) is defined by sleep apnea with decreased oxygen saturation, excessive snoring with daytime sleepiness, and frequent awakening during the night time sleep. The present study was performed to investigate how apnea-hypopnea, that possibly causes breathing disturbance during sleep, can affect sleep pattern in patients with OSAS. We included 115 patients (92 men, 23 women) who underwent a polysomnography from January 2006 to May 2007. As the frequency of sleep apnea-hypopnea increases, the proportion of non-rapid eye movement (REM) sleep (p<0.001), and stage I sleep (p<0.001) increased, while that of stage II sleep (p<0.001), stage III and IV sleep (p<0.01), and REM sleep (p<0.05) decreased. Furthermore, sleep apnea-hypopnea was closely correlated with REM sleep (r=0.314, p<0.001), stage I sleep (r=0.719, p<0.001), stage II sleep (p=-0.342, p<0.05), stage III and IV sleep (r=-0.414, p<0.001), and REM sleep (r=-0.342, p<0.05). Stage I sleep could account for the 51% of the variance of apnea-hyponea. Our study shows sleep apnea-hypopnea affects sleep pattern in pattern with OSAS significantly, and the change of stage I sleep is the most important factor in estimating the disturbance of sleep pattern.

The purpose of this study was to report a case of an insomnia patient treated with a traditional Korean medical treatment. The patient had suffered from insomnia for 4 months and had taken medicines such as Zolpidem. We diagnosed the patient as So-yang-in, according to the Sa-sang constitutional medicine. We prescribed medicine with herbs for So-yang-in and applied acupuncture for 9 days, and then we evaluated sleep time, quality, and awakening, based on the patient’s statement. The symptoms of insomnia were gradually improved during treatment. Therefore, traditional Korean medical treatment can help insomnia patients sleep well without Zolpidem.

The objective of this study is to investigate the process of development of social work and divide it historically during the Korean Modern Times. At first, I investigated this period's "societal" situation (political, economical, social situation) which is closely related to social work and made a historical division. And I wrote down the social welfare policy and social services concretely and I interpreted this period's historical meaning. At the end of the Cho-Sun dynasty, although a modern social work movement had come about naturally in the Korean peninsula, it was nearly destroyed by the Japanese aggression. However, it could have expanded consistently and come to maturity because of a national self-awakening and peoples' vigorous participation after the 3 1 national movement. But unfortunately, as the social work come to be exploited by the Japanese Imperialist powers, it lost its purity its essential purpose and was changed. After World War II, no one was made to take responsibility for those historical facts, and under the name of Social Welfare many ordinary citizens became scapegoats, and passed silently over to the period of American military occupation which was another time of transition in the Korean peninsula. There have been few studies undertaken concerning social welfare during the Japanese occupation. These studies will help to indicate what influence the Japanese had on the development of Korean social welfare after the Japanese occupation. I anticipate many studies on this subject will follow.

Purpose: The purpose of this study was to identify the effects of auricular acupressure therapy on sleep disorder and fatigue in menopausal women. Methods: The study design was a non-equivalent control group pretest-posttest design. The participants were 40~60 years old women, assigned to the experimental group (n=25) or the control group (n=27). Auricular acupressure using vaccaria seeds was administered to the experimental group. The sessions continued for 6 weeks. Outcome measures included Pittsburgh sleep quality index, sleep meter, sleep diary, fatigue assessment instrument, serum cortisol, and serum serotonin. Results: Menopausal women in the experimental group showed significant increases in deep sleep, light sleep, serotonin level and sleep duration compared with the control group. Also, the experimental group reported decreases in PSQI, sleep latency, awakening time, fatigue and cortisol level compared with the control group. Conclusion: Results show that auricular acupressure using vaccaria seeds is considered as an effective treatment for sleep disorder and fatigue in menopausal women. We conclude that it can be used as a nursing intervention method proven to reduce sleep disorder and fatigue in menopausal women.
