Purpose: This study was to identify the relationship between fatigue and sleep disturbance in adult women so as to provide basic data for developing a women's health promotion program and nursing intervention. Method: A convenience sample of 184 women who visited a Well-baby clinic at P city Maternal child center during October in 2004 was obtained. Data was collected by self-administered questionnaires. Results: The Subjects' mean age was 36.87 years and 70% were employed and had more education than high school. The mean level of fatigue was 56.65, mean sleeping hours were 6.54, and time until falling asleep was 17.58 minutes. Scores of fatigue differed by subject's age, level of education, and menstruation status. In addition, sleeping hours differed by age, occupation status, and income level. There were significant low levels of correlation between fatigue and sleeping hours (r=-.16) and getting up too early (r=-.15). Conclusion: This study concludes that fatigue and sleeping patterns have a significant relationship.

It was previously reported that cytochrome P$_{450}$ content in liver was increased when Capsicum acetone extract was given chronically to rats. The present study is aimed to investigate the effect of capsaicin, a principal component of red pepper, on the drug metabolizing enzymes in rat liver. Capsaicin (5mg/kg) was given intraperitoneally once a day for seven days and zoxazolamine paralysis time and hexobarbital sleeping time were determined 24 hrs after the last dose of capsaicin. Plasma hexobarbital concentration was also determined five and 15 min after hexobarbital administration to rats. Zoxazolamine paralysis time and hexobarbital sleeping time were shortened by 31.6% and 37.1%, respectively, compared with control group. Plasma hexobarbital concentration was lowered by 26.2% after five min and by 35.2% after 15 min, respectively, compared with control group. However, administration of single dose of capsaicin did not affect the zoxazolamine paralysis time and hexobarbital sleeping time. Microsomal cytochrome P$_{450}$ content and NADPH-cytochrome C reductase activity were increased by 14.6% and 11.6%, respectively in the rats pretreated with capsaicin for seven days, while cytochrome b$_{5}$ content was not changed. These results suggest that treatment with capsaicin for seven days may induce the drug metabolizing enzyme in rat liver.

In the previous experiments, we reported that ethanol extract of Gastrodiae Rhizoma, the dried tuber of Gastrodia ElataBlume (Orchidaceae) increased pentobarbital-induced sleeping behaviors. These experiments were undertaken to know whether 4-hydroxybenzaldehyde (4-HBD), is one of the major compounds of Gastrodiae Rhizoma increases pentobarbital-induced sleeping behaviors and changes sleep architectures via activating GABA_A-ergic systems in rodents. 4-HBD decreased locomotor activity in mice. 4-HBD increased total sleep time, and decreased of sleep onset by pentobarbital (28 mg/kg and 40 mg/kg). 4-HBD showed synergistic effects with muscimol (a GABA_A receptor agonist), shortening sleep onset and enhancing sleep time on pentobarbital-induced sleeping behaviors. On the other hand, 4-HBD (200 mg/kg, p.o.) itself significantly inhibited the counts of sleepwake cycles, and prolonged total sleep time and non-rapid eye movement (NREM) in rats. Moreover, 4-HBD increased intracellular Cl⁻ levels in the primary cultured cerebellar cells. The protein levels of glutamic acid decarboxylase (GAD) and GABA_A receptors subunits were over-expressed by 4-HBD. Consequently, these results demonstrate that 4-HBD increased NREM sleep as well as sleeping behaviors via the activation of GABA_A-ergic systems in rodents.

This paper considers the problem of combining multiple strategies for solving sleeping bandit problems with stochastic rewards and stochastic availability. It also proposes an algorithm, called sleepComb(${\Phi}$), the idea of which is to select an appropriate strategy for each time step based on ${\epsilon}_t$-probabilistic switching. ${\epsilon}_t$-probabilistic switching is used in a well-known parameter-based heuristic ${\epsilon}_t$-greedy strategy. The algorithm also converges to the "best" strategy properly defined on the sleeping bandit problem. In the experimental results, it is shown that sleepComb(${\Phi}$) has convergence, and it converges to the "best" strategy rapidly compared to other combining algorithms. Also, we can see that it chooses the "best" strategy more frequently.

The purpose of this study was to investigate the relationship between perceived stress and exercise and sleeping of high school girls. For the survey, 1829 respondents were randomly selected from Seoul and local area. The survey was conducted from the 1st to the 14th of June, 1991 by the use of questionnaires made·after a pilot study. For the analysis, descriptive statistics were used by calculating frequencies, percentages and mean scores. t-test, ANOVA and Pearson's correlation coefficient were employed to test the differences and the statistical significance. The results of this study are summarized as follows: (1) 'There was no significant difference in stress level between the subjects who took exercise and who didn't take exercise. (2) Significant positive correlation was revealed between stress level and sleeping time. It means that a increase in stress level brought on increased sleeping time. (3) Residential makes the significant differences in terms of stress level. The stress level of Seoul students(3.0l) showed higher than that of local students(2.65). The results of the study lead us to the suggestion that, for the high school girls, the health education for stress management must be required. In addition, adolescents welfare work would be reached by supporting the group activity and sufficient leisure facilities.

Perillae Herba has been traditionally used for the sedation in the oriental countries. Therefore, this study was conducted to determine whether Perillae Herba ethanol extract (PHEE) enhances pentobarbital-induced sleeping behaviors in animals. In addition, the possible mechanisms are demonstrated. PHEE (12.5, 25 and 50 mg/kg. p.o.) reduced the locomotor activity in mice. PHEE reduced sleep latency and augmented the total sleep time in pentobarbital (42 mg/kg, i.p.)-induced sleep in mice. Furthermore, the number of sleeping mice treated with sub-hypnotic pentobarbital (28 mg/kg, i.p.) increased. PHEE (50 mg/kg. p.o.) decreased the sleep/wake cycles and wakefulness, and increased total sleeping time and NREM sleep in electroencephalogram (EEG) of rats. In addition, PHEE (0.1, 1.0 and $10{\mu}g/ml$) increased the intracellular $Cl^-$ level through the GABA receptors in the hypothalamus of rats. Moreover, the protein of glutamate decarboxylase (GAD) was overexpressed by PFEE. It was found that PHEE enhanced pentobarbital-induced sleeping behaviors through $GABA_A-ergic$ transmissions.

In this study the Ayurvedic formulation Dasamularista was studied for its preliminary pharmacological properties using laboratory mice. Dasamularista showed a decrease in food intake and stool formation, while the water content of stool and water intake was higher and the volume of the urine was less. Dasamularista in a slight extent reduced the intestinal motility. This constipating effect was further supported by the significant anti-diarrhoeal property of the formulation in castor oil induced dairrhoea. The tested formulation markedly increased the latent period of diarrhoea and reduced the purging index value. Dasamularista did not alter the acetic acid induced abdominal writhing. Significant reduction on the onset of sleeping time and increased duration of sleep was observed in pentobarbital induced sleeping time test.

Using switches and sensors informing the current on or off state, this paper suggests a sleeping control and remote monitoring system that not only can recognize the sleeping situations but also can control for keeping an appropriate sleeping situation remotely, And we show an example that this system is applied to the healthcare sleeping mat, Our system comprises the following 3 parts: a part for detecting the sleeping situations, a part for extracting sensing data and sending/receiving the relating situated data, and a part controlling and monitoring the all of sleeping situations. In details, in order to develop our system, we used the touch and pressure-sensitive sensors with On/Off functions for a purpose of the first part, The second part consists of the self-developed embedded board with the socket based communication as well as extracting real-time sensing data. And the third part is implemented by service modules for providing controlling and monitoring functions previously described. Finally, these service modules are implemented by the TMO scheme, one of real-time object-oriented programming models and the communications among them is supported using the TMOSM of distributed real-time middleware.
