Recently, the space organization of Korean-Chinese houses is different from that of other territories. The vast land of China, coming from different hometown in Korean peninsula, and the different hometown in Korean peninsula, and the different procedure of settlement seem to make the different space organization of Chinese-Korean single family housing at the urban area in Liaoning Province.The characteristics of the Korean-Chinese space organization of single family housing at the urban area in Liaoning Province are as follows;i)Three types of space organization are central kitchen type, central corridors types, and central living room type. ii)The central kitchen type is mainly in old urban housing, after 1980's, the central corridor type appears in single family housing, and central living room type appears 1990's.iii) It seems that the main reason to change the space organization are fuel, system of heating, influence of Korea housing. Especially, Korean-Chinese like central living room type that is suitable for sit down living style. This central living room type supposes to be used as popular space organization in urban housing.

The purpose of this thesis is a searching out the characteristics of Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism and its influences on Korean modern dwellings especially in the time of 1930's. At the early stage of the colonial time($1905{\sim}1919$), the central corridor type Japanese dwellings were implanted into Korea for the Japanese official residences. The central corridor type Japanese dwelling was an urban modern dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. After the 1920's the central corridor type Japanese dwellings have spreaded itself and became a prototype of a modern dwelling in Korea. The characteristics of the central corridor type Japanese dwellings have influenced on the Korean high class dwellings and Korean architects' proposals for modern dwelling in the time of 1930's. By the implantation and spread of the central corridor type Japanese dwellings, Korean modern dwellings at the same time have affected and undergone transformation. The aspects of transformation were ; The outbreaking of the Japanese style entrance and central corridor, the transformation of MaDang from the inner court with a function of circulation into the outer court garden with plants and the transformation of Korean dwellings from the rural inner court type into the urban outer court type. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.

In the time of the rule of Japanese imperialism, Japanese style official residence played major role at the implantation of modern dwellings into Korea and its influences on Korean modern dwellings are distinguishable. This study focuses on the Japanese style official residence implanted into Korea before 1910. Before 1910 Japanese civilians in Korea builded just a traditional Japanese dwellings at the Japanese settlement in the ports opened. But Japanese engineers engaged in governmental organization of construction in the Old-Korean Empire builded a central corridor type Japanese dwellings as official residence. The central corridor type Japanese dwelling was an urban dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. It is certified that the central corridor type Japanese dwelling was implanted into Korea before 1910 and this was the first time an urban dwelling to be implanted and spread through the whole Korea. The central corridor type Japanese dwelling implanted into Korea took in On-Dol and transformed to Korea-Japanese eclectic style. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.

과학 탐구 활동은 학습자들 간의 협동학습을 통해 문제를 해결하는 학습 방법이다. 학습자 중심의 상호작용을 전제로 한 과학 탐구 활동을 구조적 차원에서 분석하는 것이 필요하다. 사회네트워크 분석법은 구성원들의 상호작용을 분석하는데 주로 사용되는 방법이다. 본 연구는 5인 1조 31개 조로 구성된 과학영재들을 대상으로 소집단 과학 탐구실험 활동에서 나타난 구성원 간의 상호작용의 양상을 수치적 특성을 바탕으로 유형화하였다. 이 연구의 결과는 다음과 같다. 과학영재들의 상호작용 유형은 모두 여덟 가지로 나타났다. 이 중 가장 많은 상호작용 유형은 전체 31개 조 중 모두 9개 조에서 나타나 29%를 차지한 유형 1로 세 명의 구성원이 상호작용 하는 경우였다. 이들 유형은 다시 한 구성원을 중심으로 나머지 구성원들이 모두 연결 관계를 형성하는 참여형과 중심적 역할을 하는 구성원이 없이 소외된 구성원이 존재하는 소외형으로 구분할 수 있다. 참여형은 유형 4, 유형 6, 유형 7, 유형 8로 모두 9개(29%) 조에서, 소외형은 유형 1, 유형 2, 유형 3, 유형 5로 모두 22개(71%) 조에서 나타났다. 즉, 한 구성원을 중심으로 모든 구성원이 상호작용에 참여하는 형태보다는 중심적 역할을 하는 인물 없이 일부 소외된 구성원이 존재하는 가운데 나머지 구성원들이 상호작용하는 유형이 대부분을 차지하였다. 이 연구를 바탕으로 과학 탐구활동에 적절한 집단의 크기는 무임승차효과나 소외된 학생이 없을 것으로 생각되는 3명이 가장 효과적이라고 할 수 있다. 또한 중심 구성원의 유무에 따라서는 있는 경우가 더 효과적일 것으로 사료된다.

The purpose of this study is to analyze the type of ego states and stress coping style on female college students who are in the course of nursing study. This study is performed in the view of Transactional Analysis and designed to scrutinize descriptive correlations between the type of ego states and stress coping style. The subject is consists of 144 freshmen and sophomore, 138 junior and senior students group, who are students of K nursing college located in Seoul. The sampling investigation period is on Sept. 14, 2002 to Oct. 26, 2002. The measuring instrument used for Transactional Analysis ego state is 50 items Ego-gram research paper devised by Dusay(1997). For studying coping style, Folkman & Lazarus's measurement(1984) was adopted, which is translated and modified by Han, and Oh,(1990). Statistic average and standard deviation were generated by using SPSS PC+, t-test and Pearson correlation. The results were as follows: 1) In the type of ego states on both groups(lower group : freshmen, sophomore upper group : junior, senior) indicated the arithmetic apex NP(maximum value), then the point A was high and the data made a down slope to point AC. In the comparison to type of ego states between two groups, only at point CP, the data value of upper year students represented higher than that of lower year ones by C(t=2.28, p=.023). In the psychological energy level of ego states, both groups indicated average level.2) Stress coping style of whole students were highly and affirmatively dedicated to research. Consecutive consequences follow like this(high to low) : the central point of problem, search for social support, hopeful aspect and indifference. Especially hopeful aspect(t=.67, p=.05), relaxation of tension(t=-2.16, p=.03) made significant difference each other in the view of arithmetic calculation 3) While verifying coping style in terms of ego states level between lower and upper students group, In type CP, high level ego states group indicated significant difference on stress coping style area than low leveled group and made such sequences as the central point of problem, hopeful aspect, search for social support, positive interest and relaxation of tension. In type NP, sequences such as the central point of problem, search for social support, positive interest and relaxation of tension were emerged with little differences. In type A, the central point of problem, positive interest and relaxation of tension. In type FC, hopeful aspect, search for social support, positive interest and relaxation of tension. In type AC, hopeful aspect and indifference were derived significantly different(p<.05). 4) In the aspect of relation between ego states and coping style, type CP presented the central point of problem and relaxation of tension, type NP presented positive interest, search for social support and the central point of problem, type A showed the central point of problem, positive interest and relaxation of tension, type FC showed relaxation of tension, positive interest, search for social support, indifference and the central point of problem, type AC showed hopeful aspect, indifference and the central point of problem. All the sequence shown above had high-to-low procedure and represented static relations each other(p<.05).

The semi-discrete central scheme and central upwind scheme use Runge-Kutta (RK) time discretization. We do the Lax-Wendroff (LW) type time discretization for both schemes. We perform numerical experiments for various problems including two dimensional Riemann problems for Burgers' equation and Euler equations. The results show that the LW time discretization is more efficient in CPU time than the RK time discretization while maintaining the same order of accuracy.

An adjustable, louver-type wind barrier was introduced in this study for improving the running safety and ride comfort of train on the bridge under the undesirable wind environment. The aerodynamic characteristics of both train and bridge due to this novel wind barrier was systematically investigated based on the wind tunnel tests. It is suggested that rotation angles of the adjustable blade of the louver-type wind barrier should be controlled within $90^{\circ}$ to achieve an effective solution in terms of the overall aerodynamic performance of the train. Compared to the traditional grid-type wind barrier, the louver-type wind barrier generally presents better aerodynamic performance. Specifically, the larger decrease of the lift force and overturn moment of the train and the smaller increase of the drag force and torsional moment of the bridge resulting from the louver-type wind barrier were highlighted. Finally, the computational fluid dynamics (CFD) technique was applied to explore the underlying mechanism of aerodynamic control using the proposed wind barrier.

In the production of rice flour, wet milling is a method of milling rice after soaking it in water, and it takes a lot of time and cost from milling to drying. To overcome this problem, the floury type rice was developed for dry milling and it is known to have round starch granules, low content of damaged starch after milling, and a starch structure similar to wheat. Because of its unique properties different from normal rice, it is necessary to research on processing and characteristics of floury-type rice to expand its utility in the food industry. Therefore, this study aimed to prepare the pregelatinized floury type rice (Baromi2) by autoclave and investigate their physicochemical properties. As the heat treatment time increased, the brightness decreased from 83.8 to 76.8, however, both redness and yellowness increased from 0.57 to 4.5 and from 14.58 to 21.13, respectively. Despite of same treatment time, soaking in water (10 min) before autoclaving increased the solubility and swelling power of Baromi2 over 2 times. The peak viscosity of native Baromi2 was over 2000 RVU, on the other hand, there was a significantly decrease to less than 1000 RVU of pregelatinized Baromi2. Heat treatment without immersion caused partial gelatinization of starch, resulting that some starch granules maintaining their integrity. Whereas there were no starch granules in heat treatment with soaking in water due to complete gelatinization. This study would be helpful to the suggestion of using heat-treated floury-type rice as an intermediate material in the food industry in the future.
