In the meantime, the study of traditional and contemporary house had been produced so many achievements in korea, but modern house is yet to be solved, Accordingly, It is necessary to develop and present the basic research data in order to build up an objective study for urban house in the modern age(1910-1945), Following to a study on the foreigner's house in grid-type settlement of Open Ports, in this research is to investigate and analyze modern houses of urban areas in korean inland, and then clarify types and changes of them. In the first year(1995~96), the modern houses of Central Inland Districts(arrounding river Kumgang)-Kunsan kanggyong Puyo Kongju Pugang Chongju were investigated by the layout of room, the construction and materials, the design and style, etc. In the second year(1996~97), the modern houses of Open Market(開市場)-Seoul Taegu Kwangju Taejon Chonju were conducted to investigate as above. The traditional house transformed by differentiation and addition of room(kan), the various types were respectively adopted for the korean reforming and western cultural house. In the layout of room, the types of plan were gradually concentrated from the single wings of korean traditional house. The korean traditional house was later improved through the introduction of entrance, corridor, and internal toilet/bathroom. But the korean under-floor heating system(andal) and a series of three rooms had been entirely maintained, composed of master bedroom/living room(daechung)/room. And the traditional town house with shop and storage, being built closely to each other and walled up both sides, it had taken gradually the extensive characteristics in itself. By the displacement of shop/dwelling/ storage. the various types were respectively adopted for the separated, multi-storied, and complex type. The type of them was gradually changed to the narrow and linear form. And so with the stockpile of fundamental datas about modern houses in korean urban areas, we expect these results contribute to the knowledge of the spatial characteristics of urban house at present which are required to the understanding of transition as well as types.

장경비가 큰 탄화규소를 탄소와 규소간의 고온연소반응으로 제조하기 위하여 공정변수에 따른 연소거동과 미세조직의 변화를 조사하였다. 연소합성된 생성물은 주로 β-SiC이며 연소반응이 충분히 진행되지 못하였을 경우에는 미량의 잔류 반응물과 α-SiC가 관찰되었다. 생성된 탄화규소의 평균입도는 약 5μm로 작았으며, 1300˚C 이상의 예열 조건에서 장경비가 30이상인 탄화규소를 합성할 수 있었다. 압분 강도가 69MPa인 분말의 성형체에서 평균 연소 온도와 평균 전파 속도는 각각 약 1425˚C와 2.1mm/sec 범위이며, 연소 온도는 흑연 분말을 사용하였을 경우가 탄소 섬유를 사용한 경우보다 약 10˚C 높았다. 연소 반응을 임의로 중단시킨 시편의 계면을 EDX와 Auger 전자 현미경으로 분석한 결과 상호 확산층이 관찰되지 않았다. 이는 탄화규조의 연소합성이 용해-석출 모델에 의하여 진행됨을 시사한다. 예열 온도에 따른 연소 반응 중의 온도 분포를 유한 요소법으로 해석함으로써 2500˚C의 초기 연소 개시 온도에 대하여 예열 온도 300˚C에서는 연소파가 거의 전파할 수 없으며 예열 온도가 1300˚C에서는 시료 내부에 자체 전파가 가능한 2000˚C이상의 온도 구역이 존재함을 알았다.

This study has been researched mainly about the gradual changing patterns of site plan and plan layout of 17 sampling traditional houses in kyungpuk province during the time period of 1877-1945. The objective of this study is to closely examine the characteristics of locality and trend of the times. Survey and Measured drawing, personal interviews with clients has been carried out and the result is as down below; 1.The certain changes have shown that the furnace in sarangchae(outer wing for men) in ㅁ shaped and 『』 shaped houses served only for that purpose and inner gate has been built in sideward of sarangchae. 2.As living standard was upgraded storage space and size of the rooms got bigger. On the other hand, spacial formation was emphasized by its function accordding to house activities and living circulation because the family members in direct line became reality of the time. 3.The modernistic thought of rationalism and convenience are well expressed in the plan layout and house living as a whole.

돌연변이체인 or (orange body) 계통과 KNIH (Korea National Institute of Health) 계통의 바퀴(Blattella germanica (L.) (Orthoptera: Blattellidae)를 반자연적인 조건하에서 비디오와 컴퓨터 자료처리를 통하여 연속적으로 관찰하였다. 휴식처에 머무르거나, 먹고, 물 마시며, 다른 개체들과 교신하는 행동을 관찰 할 수 있는 사각형의 관찰상자 내에서 수컷 성충을 개체별로 4~5일 동안 연속적으로 관찰하였는데, 본 논문에서는 휴식처에 머무르는 시간과 방문 빈도를 분석하였다. 개체들 간의 변이가 상대적으로 컸지만 시험개체들은 휴식처에 전체 관찰시간의 47 -61%를 평균적으로 머무르는 것으로 나타났다. 판찰 개체가 휴식처에서 머무르는 시간은 모계에 따른 유의한 차이가 있었으나, 계통 사이에는 뚜렷하게 구분이 되지 않았다. 명암기의 차이는 두 계통 모두 관찰되었는데 휴식처에 머무르는 시간은 암기보다 명기에서 더 길었다. 휴식처 주변의 국소적 활동성을 나타내주는 방문빈도는 KNIH 계통보다 or 계통에서 상대적으로 높게 나타났는데, 모계와 계통간에 유의한 차이가 있었다. 방문빈도의 명암기 차이는 or 계통에서는 유의하게 나타났지만 KNIH 계통에서는 없었다. 개체들 간의 변이가 있었으나 동일한 모계 내에서 휴식처에 머무르는 시간이나 방문빈도가 유사하게 관찰되는 개체들이 있었다.

Several studies have evaluated the effects of types of relative frequency and delay interval of knowledge of results(KR) on motor skill learning independently. The purpose of this study was to determine more effective types of KR relative frequency and KR delay interval for motor learning. Forty-six healthy subjects (15 female, 31 male) with no previous experience with this experiment participated. The subjects ranged in age from 20 to 29 years (mean=23.9, SD=0.474). All subjects were assigned to one of four groups: a high-instant group, a high-delay group, a low-instant group, and a low-delay group. During the acquisition phase, subjects practiced movements to a target (400 mm) with either a high (83%) or low (33%) KR relative frequency, and with either an instantaneous or delayed (after 8s) KR. Four groups were evaluated on retention (after 3min and 24hr) and transfer (450 mm) tests. The major findings were as follows: (1) there were no between-group differences in acquisition and short-term retention (p>0.05, (2) a low (33%) KR relative frequency during practice was as effective for learning as measured by both long-tenn retention and transfer tests, compared with high (83%) KR practice conditions (p<0.05), (3) delayed (8s) KR enhanced learning as measured by both long-term retention and transfer tests, compared with instantaneous KR practice conditions (p<0.05), and (4) there were no interactions between KR relative frequency and KR delay interval during acquisition, retention, and transfer phases. The results suggest that relatively less frequent and delayed KR are more effective types for motor learning than more frequent and instantaneous KR.ㅂ

This experiment was carried out to evaluate the effect of pasture type on behavior pattern, change of body type and daily gain of Korean native goat at the College of Natural Science of Kon-KuK University in Chungju. The results are summarized as follows

The typical Japanese house has the characteristics of open dwellings to make them cool in the hot and humid summer. And then the traditional town house 'Machiya', being built very closely to each other and walled up both sides, it has taken the open-oriented characteristics in itself. The purpose of this study is to clarify that the open-oriented of traditional 'Machiya' has been succeeded to the new 'Machiya' in the latest. The new 'Machiya' shows the open-oriented, taking the ventilative 'Huki-nuke' space of traditional 'Machiya' as the new spatial formal elements, in the changes such as scale material space organization. The characteristics of 'Huki-nuke' space are represented as follows ; 1. The facade of the traditional 'Machiya', which has taken on a semitransparent qualty, has been generally changed to the closing qualty except for the open parts of shop and garage. This facade of the new 'Machiya' has been taken to be in keeping with the existing town as much as possible. 2. A series of three rooms, composed of shop/living dining kitchen/room from the road, have been dispersed to every floors in a building with a very extensive scale. But this serial and linear type remains as the loosefit space, and the long dwellings of the upper stories are divided by type each dwelling unit. 3. 'Tori-niwa', which is a consecutive and penetrating space, connects the road with the rooms of dwelling and functions as the circulation of man thing energy, The new 'Machiya' changed to the multi-story, the corridor and the stair have been fumed up as the elements in the place of 'Tori-niwa' The 'Huki-nuke' space was locted in the hall, stairwell, living dining kitchen room, and so on. 4. The small court yard 'Tsubo-niwa' and back yard 'Ura-niwa' at the both ends of living spaces would be made a hole in a series of rooms and enclosed by the neighboring 'Machiya'. On the contrary the new 'Machiya' at present takes in the private and closing organization enclosing the innercourt. 5. The open-oriented 「In」 or 「Out」 is not brought out because of the delicate spatial formal configuration in the traditional 'Machiya'. But the open-oriented 「In」, all sides being closed by walls, is well brought out in the new 'Machiya'.

The objective of this experiment was to compare the dry matter intake, nutrients digestibility, nitrogen and energy utilization of hehage among the orchardgrass(OG) pure, orchardgrass(OG)-red clover(RC) mixture and complex rnixtures(C. mix) by Korean nati

After 1960, staple food consumption pattern of Korea underwent a significant change from the former rice-barley pattern to the present rice-wheat pattern. Therefore the present staple food consumption pattern of Korea may be defined as a mixture of grain and flour consumption.

How have they preserved the regional historic buildings in Korea? Do they preserve the original value as a historic building. Are there any artificial deformations deteriorating the quality of the buildings? Is the regional system for preservation effective agalnst the artificial deformations of the buildings? These questions are involved in the purposes of this paper. I investigated the historic buildings designated by Kyong-Nam provincial government. As the resuit, variouse patterns of artificial deformation were found. I found that the deformations may deteriorate the original quality of historic building, and it is related somehow to the limitations of regional system for preservation. So I suggest some alternative ideas for preserving the quality of historic buildings against artificial deformation : a. Present system for preservation is not effective for preserving various architectural value such as urban context and landscape, site planning techniques, function of a space, etc. Regional system should be revised for preserving their architectural value or meaning. b. Historic buildings should be classified and should have proper protecting area according to each architectural values or meanings, respectibly: Historic buildings with Urban context and landscape Historic buildings as a part of a complex Historic buildings as a behavorial setting. c. Historic buildings should be graded based on their quality. And standard and criteria for acceptable deformations should be established. d. Periodical inspections by experts should be carried out to check out the deformation.
