An academic article is normally cited within a few years of publication, after which interest falls off as the research field moves on. However, an article is sometimes ignored for many years only to attract interest after a long period of dormancy. Such articles are called "Sleeping Beauties." A general characterization of this pattern has recently been defined and is used in this study to identify five Sleeping Beauties that were published by researchers at the University of Waterloo in the 1970s and 1980s. While a handful of studies have examined the occurrence of such Sleeping Beauties in specific fields of research or in a particular journal, none has yet identified these unusual articles in the context of the lasting impact of a university's research. This study is therefore a novel application of the latest technique for identifying Sleeping Beauties. The possibilities for using this unusual citation pattern in raising the profile of a university's research are discussed.

To investigate the sleeping patterns and gastrointestinal disorders of shift workers, the author studied 434 female workers who worked at textile industry ill Taejon city from September 1,1992 to September 31,1992. Shift pattern were divided into 3 categories ; 3 shift(shifts per 8 hours), 2 shift(day and night shift) and day work. The results obtained were as follows : 1 The average sleeping hours when adjusted for the education level of the total study subjects was 6.1 hours. That of 3 shift workers was 6.1 hours, 2 shift workers was 6.0 hours, but that of day workers was 6.5 hours. There were no significant difference among the shift workers. 2. For the 3 shift workers, the average physiologic adjusted duration in day shift (2.2 days) was shorter than that of night shift(2.7 days) and there were significant difference among the rotating shift works (p<0.001). The sleeping problems in day shift was less than those of night shift (p<0.001). 3. 44.9% of 3 shift workers, 39.3% of 2 shift workers and 33.1% of day workers complained gastrointestinal symptoms when adjusted for the age, education level, job tenure, work post. And the rates of gastrointestinal symptoms complained increase with job tenures (p<0.001). 4. The most frequent gastrointestinal diseases were gastitis and gastric ulcer with 14.2% , Irritable bowel syndrome with 3.1 %, duodenitis and duodenal ulcer with 2.1% and combined gastrointestinal disease with 2.1%. Age, eating habit, amount of coffee per day, job tenure, work post and shift pattern showed no significant difference with the gastrointestinal diseases when adjusted for the age. According to the above results, the author suggested that the shift pattern and job tenure can affect to the sleeping problem and gastrointestinal symptoms.

The purpose of this study is to fined out the characteristics of using & change of the residential space according to the children age and family life cycle. The results of this study are as follows: The first, as children grow up, children's activity space changed from living room to the private room, and housing condition was related to the frequency of each activity. The second, as children grow up, family's sleeping pattern changed, and this change effected the number of private rooms for sleeping and the use of the extra room. The third, changes of the using of dwelling space come out several pattern, increasing bedroom number through reconstruction, exchange of An-band and children room, parents' sleeping space move to living room, and change the function of rooms. The change pattern of the correspondence to the housing needs differed from each family life cycle stage.

This study examined the changes in sleeping and studying patterns of young students and their mothers after moving to foreign countries. This study analyzed the relational characteristics of Geese Family members which are summarized as follows: 1) Sleeping Pattern: At the early stages of settling into foreign countries, students begin to sleep in the same bedroom with their mothers, who had used to sleep in separate bedrooms back in Korea. This change in pattern may slightly vary according to the age and gender of the students, and type of residence. Relationships between young students and mothers become more tightly coupled. However, relationships between students and fathers become less tightened. 2) Studying Pattern: Students tend to study in the public space such as the living room and dining areas, rather than in their own private rooms. This is because mothers want to support and focus upon their children's study by sacrificing normal family activities. These patterns appear stronger as their period of study in the foreign country becomes shorter and the ages of the students become younger. These studying patterns also contribute to the coupling between mothers and young students. 3) Family Relationships: From the period as Geese Families, the relation between mothers and young students become closer both physically and emotionally. The relation between fathers and children become less close. The role of fathers is degraded to that of supporter or negotiator for the time period of the mothers and child students in the foreign country.

As a study on activities associated with sleeping, this paper is aimed to trace a behavior log by differentiating human behavior patterns. Toward this research purpose, we define a behavior log and a simplified feature vector about human behavior patterns associated with sleeping. Then, based on thresholds of the feature vector, we did experiments applying the individual-base behavior pattern decision algorithm to human behavior patterns. The important results derived from these experiments indicate that the proposed approach reflecting individual behavioral characteristics is more useful than the existing single group approach.

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.

The purpose of the study was to identify the living pattern and the space use in Urban Houses, Seoul, Chunju, Ulsan were selected as study sites. The space organizing form and space use was investigated by means of interviews. Through various ways of analysis, we could find that the function of Anbang, Guesil, Buauk were multipurpose. Anbang was not only for sleeping but also for entertaining and family living. Guesil(living room) is slowly gearing into family and entertainment rooms. Buauk are changing to the dining room as well as kitchen.

Objective: Environmental change is one of the stressful events in livestock production. Change in environment disturbs cow behavior and cows require several days to regain a stable behavioral pattern. Sleeping posture (SP) and lying posture (LP) have been used as indicators for animal that are relaxed and well-acclimated to their environment. The aim of this study was to examine the time required by Japanese black cows for stabilization of SP and LP after moving into new environment. Methods: Seven pregnant Japanese black cows were used. Cows were moved into new tie-stall shed and their sleeping and lying posture measured 17 times during 35 experimental days. Both SP and LP were detected by accelerometer fixed on middle occipital and hip-cross, respectively. Daily total time, frequency, and average bout of both SP and LP were calculated. Results: Daily SP time was the shortest on day 1 and increased to the highest on day 3. It then decreased until day 9, after that stabilized about 65 min/d till the end of experiment. Daily LP time changed in same manner as daily SP time. The average SP bout was the longest on day 1, and then decreased to stable level on day 7. On the other hand, the average LP bout was the shortest on day 1, and it increased to stable level on day 7. Conclusion: These results showed that pregnant Japanese black cows needed 1 week to stabilize their SP. However, there were different change patterns between the average SP and LP bout, even though the change pattern of daily SP and LP time were similar.

In this paper, we propose a system that collects data from sensors that detect the sleeping environment and adjusts the sleeping environment optimally based on the environment to help you get a good night's sleep. The sleep environment analysis is based on the determination of the sleep stage by detection of twisting through the load cell. In addition, based on data such as temperature, humidity, and illuminance, heat devices, humidifiers, blinds, etc. are controlled to create an environment in which to have a good sleep. The sleep environment control according to the sleep state can reduce fatigue when waking up by inducing a sleep state that is easy to wake up.

Ethanol extract of the root of Clitoria ternatea Linn (CTEE) was evaluated for different neuropharmacological actions, such as general behaviour, exploratory behaviour, muscle relaxant activity and phenobarbitone induced sleeping time, in rats and mice. The extract was found to cause reduction in spontaneous activity, decrease in exploratory behavioural pattern by the head dip and Y- maze test, reduction in the muscle relaxant by rotarod, $30^{\circ}C$ inclined screen and traction tests. In addition CTEE significantly potentiated the phenobarbitone-induced sleeping time. Preliminary tests indicate that the ethanol extract of Clitoria ternatea Linn. At the doses of 100 and 150 mg/kg showed significant neuropharmacological activity.
