Objective : This study was undertaken for discovering the characteristics of sleep in ordinary symptoms based on the Sasang Constitution. The result of this study could be helpful to understand and to identify patients such as Taeumin, Soyangin Soeumin or Taeyangin. Methods : There were 1,229 patients (529 men), who answered the questionnaire about their ordinary sleeping patterns. They were diagnosed, including their clinical Sasang Constitution, by the Sasang Constitution specialist at Bundang Oriental Hospital of Dongguk University. By applying the multinomial and binary logistic regression analysis to those collected materials, we can measure the characteristics and the influence of ordinary sleeping patterns to the dependent variable (Sasang Constitution). Results : In order of the item's influence that had decided one's constitution, between Taeumin and Soeumin, Taeumin snored frequently or well more than Soeumin, Soeumin had more dreams and more sleeping times than Taeumin, and Taeumin struggled frequently or well more than Soeumin. Between Soyangin and Soeumin, Soeumin dreams more frequently than Soyangin, Soyangin snored frequently or well more than Soeumin, and Soeumin has more sleeping times than Taeumin. Between Taeumin and Soyangin, Taeumin snored frequently or well more than Soyangin. Between Taeyangin and a group of the other constitutions, Taeyangin felt unwell after sleeping more than the other constitutions, the other constitutions awaked frequently more than Taeyangin during sleeping. Conclusion : This study will be used for identifying patients as Taeumin, Soyangin, Soeumin or Taeyangin by contrast with each other.

Objectives : The purpose of this study is to examine sleeping patterns and diet patterns of the children in day-care centers in Seongdong-district and to find out the relationships between those two patterns and children growth. Methods : 686 day-care center kids participated in the examination. We measured their heights and weights. We also conducted a questionnaire survey (of them) on their sleeping patterns and diet patterns. Based on the findings, we have analyzed correlations of the factors. Results : 1. We have interviewed 686 children in day-care centers in Seongdong-district. Substantial survey was conducted to 672(14 kids didn't go through regular medical checkups). Their age ranged from 4 months to 120 months and weights covered from 6.20 kg to 50.80 kg with the average of 16.97kg. Their height ranges were from 70.4cm to 140.6cm and the average was 100.76cm. 2. The survey results showed that birth-height affects children's current height. The results from the group of age over 25months and the group covering 2 to 6 years indicated that birth-height affected the current height as well. However, the result from the age group over 37 months showed that birth-height didn't relate to the current height. 3. Results from questionnaires on sleeping patterns indicate that children sleeping longer are taller than the other. Results of other questionnaires showed no substantial relations to height. 4. Results from questionnaires on diet patterns, cold food eating habit affects growth. Conclusions : According to the results above, sleeping patterns substantially affects the growth. In order to find out, however, the specific relations between them, further research would be necessary.

In the knowledge-based economy, firms are increasingly exploiting their intellectual properties, especially patents. However, firms usually fail to commercialize all of their patents and some of them are not used even for strategic purposes. Therefore managing sleeping patents constitutes one important aspect of firms' overall patent strategies. This paper considers market uncertainty, technology uncertainty and strategic uncertainty as the reasons for sleeping patents. We analyze how firms' patent-related activities can reduce sleeping patent ratios. The firms' activities examined in here are patent audit, preliminary evaluation, prior art and cooperation. Noticing the prevalence of sleeping patents, this paper contributes by providing insights into how firm's activities affect the sleeping patent ratios. Insights for practitioners and policy makers have been provided from the empirical results.

In my previous paper (2009), I defended a solution of the Sleeping Beauty problem, according to which, on Monday, Sleeping Beauty assigns a lower credence to the coin's landing heads than 1/2. This conclusion was largely favorable to the Thirder view. However, even if my defense of the Thirder view was successful, it left one important question to be unanswered: Where did the Halfers go wrong? Their main argument was simple: Because Sleeping Beauty does not receive new and relevant evidence about how the coin lands, her credence in its landing heads should remain to be the same. But note that, if the Thirder view was right and Sleeping Beauty receives no new and relevant evidence, then this becomes a special case of the so-called old evidence problem (Glymour, 1980). In this paper, I will explain why it is rational for Sleeping Beauty to change her credence despite the lack of new evidence about the coin's landing heads. For this explanation, I will use Garber's well-known solution to the old evidence problem.

The purpose of this paper are to analyze about sleeping and eating habits of children and to propose short and long-term plans for problems. To analyze problems of sleeping and eating habits of children, we did survey for children. The oriented children of survey are students who are the third grade or sixth grade of elementary school. They are distinguished between rual and urpan area. The main of survey are the purpose of using computer, computer using time, daily sleeping time, the quality of sleeping, the cause of insufficient sleep and change of eating habits by using computer. According to result of survey, computer using time affect sleeping and eating habits in case of a part of children. Therefore, a teaching plan for computer using habits is needed in elementary school.

The object of this study is to evaluate confounding effect of sleeping behavior on heart rate variability (HRV) in healthy volunteers during a randomized clinical trial. From 6 healthy volunteer, we acquired circadian electrocardiography(ECG) with a Holter monitoring device(DigiTrak Plus, Philips). The compatible analytical program, Zymed, was used for calculation of RR intervals of 24h ECG signal. Then, we generated HRV signals and calculated 9 HRV parameters in time domain and frequency domain for every 30 minute with Matlab 6.x software. We also encoded participants' activities as follows; stable condition(1), sleeping behavior(2), eating behavior(3), and undefined condition(4). Using SPSS 12.0, we tested if there was any difference between HRV parameters of day-time and night-time and between those of a subject in stable condition and in sleeping behavior. As a result, one of the most important parameter-LF/HF ratio, which indicates the autonomic balance between sympathetic and parasympathetic nervous systems, as same the other parameters, showed large inter-individual variations in circadian profiles. And, the mean LF/HF ratio of each participant was different between in stable condition and in sleeping behavior (p<.05). Consequently, the effect of sleeping behavior must be considered when one or more of HRV parameters, especially LF/HF ratio, are used as assessment index in clinical studies.

In this paper, it introduced the device that was fabricated for monitoring sleeping positions of infants with 3-axis accelerometer. Sleep monitoring studies has been usually conducted two ways. To monitor sleeping posture by installing a camera and then recording of sleep in the sleeping room continuously is the first one. The other one is monitoring pressure sensor's results data for sleeping. Those two ways' benefits are that are able to get relatively accurate sleeping posture data but, there are many disadvantages like constraints of spaces and places, the installation of sensors or cameras, and high cost. In addition, it has a lot of problems that difficult to solve. For babies, it's not easy to apply, as well as uncomfortable. The proposed method uses a 3-axis accelerometer's X axis, Y axis, Z axis position output values in order to recognize the bad ground sleeping position that use of the buzzer alarm. This method uses a 3-axis acceleration sensor to measure the data and transmit sleeping posture using Bluetooth wireless in real time monitoring. The data is helpful for prevention safety hazard such as choked themselves when they slept back side on.

As Green-IT has attracted a lot of attention in recent years, many researches have been interested in reducing the energy consumption of network equipments. In this paper, we analyze the energy saving ratio and delay performance according to various traffic patterns and burst assemble algorithms in OBS network with sleeping mode. To do this, we design the traffic generators, which are based on exponential distribution and Pareto distribution, and the router model, which has the time based and length based burst assemble algorithms by using OPNET modeler. Through OPNET simulator, we evaluate the energy saving performance in terms of the sleeping time, the number of transitions and packet delay.

Recent ubiquitous computing environments increasingly impact on our lives using the current technologies of sensor network and ubiquitous services. In this paper, we propose ubiquitous architectural framework for ubiquitous sleep aid service(UbiSAS) in the subset of ubiquitous computing for refreshing of human's sleep. And we examine technical feasibility. Human can recover his health through refreshing sleep from fatigue. Ubiquitous architectural framework for UbiSAS in digital home offers agreeable sleeping environment and improves recovery from fatigue. So we present new concept of ubiquitous architectural framework dissolving stress. Specially, we apply context to context-aware framework module. This context is transferred to context adaptive inference engine which has service invocation function in intelligent agent module. Ubiquitous architectural framework for UbiSAS using context adaptive rule inference engine without user intervention is technical issue. That is to say, we should take sleep comfortably during our sleeping. And sensed information during sleeping is changed to context-aware information. This presents significant information in context adaptive rule inference engine for UbiSAS. This information includes all sleeping state during sleeping in context-aware computing technique. So we propose more effective and most suitable ubiquitous architectural framework using context adaptive rule inference engine for refreshing sleep in this paper.
