The study was to evaluate the air-conditioning of sleep algorithm. The algorithm was developed through the analysis of brain waves and MST, the experiments using air conditioner was performed in a apartment bedroom. Five female subjects were participated for the experiment. Eight hours of data collection a day was performed under different algorithm, case A, case B and case C. Physiological signals, EEG, ECG, EOG, and EMG, were obtained using polygraph and converted into digital signal. Then, subjects were asked to answer the questionnaire about their thermal sensation after experiment in bedroom. Sleep stages were classified, then TST, Sleep latency and Sleep efficiency were calculated for the three different air conditioner algorithm. As results, TST, Sleep efficiency, questionnaire showed the higher values for Case B algorism than that for other algorism. On the other hand, SWS latency was lower than for other conditions. Therefore, it was concluded that Case B of the algorithm was the best for comfortable and deep sleep.

It is widely accepted by researcher today that in Koguryo Dynasty, it was not until late fourth century that the conscription system was enforced, And that before this time, the military forces were composed of professional soldiers from the ruler class. However, given the population at the time, it is difficult to accept that an approximate number of 20,000 to 40,000 soldiers who were mobilized for large scale attacks at the time all came from the ruler class. Furthermore, it is equally difficult to believed that Koguryo successfully defended itself and defeated its attackers from Chinese Han, Wui, and Post-Yun Dynasty with this number of soldiers from the ruler class. This study will begin by questioning this widely accepted theory and the following points. First, Koguryo military system was based on a conscription system, Second, the King was the only supreme command and he alone could order the troops. It was considered treason to mobilize armed forces without the king"s approval. It was not until after King Sindae"s rule that a single army was divided in to central and local army. The central army had more power than the local army. The central army was stationed in the capital to play the role of protecting the king and defending the capital. Meanwhile, the local army was stationed in local areas to play the role of maintaining public security and defending the borders. The central army composed of two kinds of soldiers, Professional soldiers from the ruler class called the Kuk-in (國人), and the farmer soldiers mobilized by the conscription system who farmed in peace times and were mobilized as soldiers in times of war. The local army composed of three grade groups: Dae-sung, Je-sung, and Sung. Koguryo dynasty had great influence on Goryo dynasty and Josun dynasty, and which so did their military system.

People of modem society spend 60~70% of their time of a day staying indoors. As the importance of indoor life increases, needs for thermal-comfort has also been raised. So far, many researches on thermal comfort by controlling thermal environmental factors have been done, and studies on sound, fragrance, color, and air quality have been actively carried out by adopting emotional methods. With these research results, methods of climate control have facilitated emotional controls, that is the adoption of emotional methods to thermal environmental factors. In this study, human bodies' thermal comfort and emotions in winter heating system are evaluated. Average heating degree range is from 18℃ to 20℃, but many places actually keep their indoors heated at 24~26℃. This study aimed to demonstrate the effect of saving energy by changes of images, which are a major influence for people to heat their indoors at 24~26℃.

All over the world there is an increasing consumer awareness of the potential influence of various foodstuffs on our health. Today dairy products are expected to be more just food. They have to taste well, appeal and give pleasure, provide of well-being, provide specific health benefits and prevent disease. This paper reviews the different types of fermented milks and their microflora and includes recent work on yogurt, soft cheese and buttermilks, kefir and koumiss. There is considerable interest in the new health promoting products which are now available. Meanwhile during the last decade a new generation of fermented milk products containing selected intestinal bacteria has been introduced to the markets. These are discussed in the light of some recent findings on the ability to lower the blood cholesterol concentration and stimulate the immune response and also describes some fermented milk products available, selection criteria for commercial starter cultures.

In the early Koryo period, the Bu-By?ng military officers as the rewards for the military service were granted lands on the principle of allotting them to the selected soldiers(選軍給田制). And the Bu-By?ng military officers were controled by the public military system(公兵制) for preventing the military revolt. But as the social situation changed, the Bu-By?ng military officers came to be recruited from families belonging to the hereditary soldiering order and as a necessary consequence they came to inherit the lands. And through the military revolt in 1170, the public military system(公兵制) was collapsed and the private military system(私兵制) appeared. These two change of the "Bu-Byong" system(府兵制) lead the land tenure system and the military system to disorder. As a result, the military system in the late Koryo period became weakened. Military power was the principal factor that enabled Yi S?ng-gye(King T"aejo) to establish a new dynasty and become its first ruler. Yi S?ng-gye"s assistants suggested to reform the military as well as land tenure system and drawn up a plan of reform. Lands was to be restored to the government and be redistributed, most grants being temporary, for the support of officers. Establishing Ch?son dynasty, military reform was also pushed forward. The Bu-By?ng military officers were recruited not by his family background but by his individual ability. The success of this military reform meant a recover of traditional system of allotting lands to the selected soldiers(選軍給田制). Prince Yi Pang-won(King Taejong) who acquired the power by the political coup reformed the private military system(私兵制) into the public military system(公兵制). And as soon as he assumed the throne, he reformed again the "Bu-Byong" system(府兵制). As the result of his reform, the Bu-By?ng military officers were separated into Gapsa(甲士) and Daegang(隊長)ㆍDaebu(隊副). Gapsa(甲士) became the backbone force of the central armies but Daegang(隊長)ㆍDaebu(隊副) came to perform only ordinary corvee services.
