The plan of Korean traditional houses are devided by the span-units which is the automatic result of the timber construction. This study aims to analyze the ways plan type change when the number of span changes. One village named Bangchon in Honan Province was selected where we investigated more than 30 houses ranging from 3 span to 6 span. It is identified that there were certain rules which govern the plan change when number of span change. When one span is added onto 3 span houses, wooden floor of one span is added in between the two ondol-rooms. When one span is added onto 4 span houses, kitchen is enlarged. When one span is added onto 5 span houses, wooden floor is enlarged into 2 span, Also the plan of Man's quarter(Sarang-chae) was investigated and compared to Lady's quarter. The research proves that such rules of plan change need to be considered as a basic standard of analysis when traditional houses are to be studied.

공간(空間)과 천지(天地) - 동서양 건축에서의 공간관 -

We are so used to the concept of the term 'space' that we do not question its conceptual validity. However, this paper argues that the notion of space prevailing all over the world, is not a universal concept that can be applicable to all architectures of the world, but is a particular concept that is generated from the Western way of thinking. This paper alms to identify the conceptual structure of the idea of space as it is originated in the tradition of the West, and, as an alternative view of space, tries to identify the nature of the view of space perceived in the tradition of the Eastern architecture. Comparison of the two views, that of the East and the West, and their meaning in the future of architecture, is another task to discuss in this paper. To be able to clarify the meaning of space in East Asian tradition, a set of new perspective of understanding of space was invited. They are ; 1. sky-earth(天地); insisting that the notion of space should be replaced within the context of sky, which is one half of sky-earth totality 2. energy of the air (空氣), space is not empty part inside of a building, but is a dynamic condition of air that is a part of the sky which always exist in form of energy 3. place(자리): instead of space, which, basically. is a man-made concept, idea of place is necessary, which include not only space but also earth Such concept of space which is different from the notion of space of the West, is meaningful not only to identify the idea of space in the East, but also to be able to contribute for more dynamic, varied, and balanced understanding of space.

Alloy 600 노즐관통부의 이종금속용접 잔류응력에 따른 응력부식균열 거동 분석

김성우,김홍표,김동진,정재욱,장윤석,Kim, Sung-Woo,Kim, Hong-Pyo,Kim, Dong-Jin,Jeong, Jae-Uk,Chang, Yoon-Suk 한국압력기기공학회 2010 한국압력기기공학회 논문집 Vol.6 No.2

This work is concerned with the analysis of stress corrosion cracking(SCC) behavior of Alloy 600 nozzle penetration mock-up according to a residual stress induced by a dissimilar metal welding(DMW) in a nuclear reactor pressure vessel. The effects of the dimension and materials of the nozzle penetration on the deformation and the residual stress induced by DMW were investigated using a finite element analysis(FEA). The inner diameter(ID) change of the nozzle by DMW and its dependance on the design variables, calculated by FEA, were well consistent with those measured from the mock-up. Accelerated SCC tests were performed for three mock-ups with different wall thicknesses in a highly acidic solution to investigate mainly the effect of the residual stress on the SCC behavior of Alloy 600 nozzle. From a destructive examination of the mock-up after the tests, the SCC behavior of the nozzle was fairly related with the residual stress induced by DMW : axial cracks were found in the ID surface of the nozzle within the J-weld region where the highest tensile hoop stress was predicted by FEA, while circumferential cracks were observed beyond both J-weld root and toe where the highest tensile axial stress was expected.

비대칭전 주요사례 연구

비대칭전은 상대방이 효과적으로 대응할 수 없도록 상대방과 다른 성격 및 기능을 가진 수단과 방법으로 수행하는 작전이며 '이질성'과 '우월성'을 원칙으로 한다. 여기서 '이질성'이라 함은 적이 보유하고 있지 않거나 개발하지 못한 무기체계를 운용하여 적의 취약분야를 공격하거나 적의 능력을 파괴하는 것이며, '우월성'은 적보다 양적 질적 측면에서 압도하는 능력으로 대응하는 것이다. 비대칭 전략의 유형은 복잡하기 때문에 다양한 비대칭 전략의 유형분류가 가능하다. 따라서 비대칭전에 대한 여러 측면에서의 이해가 요구된다. 비대칭전의 관점에서 본다면, 고대전투에서 현대전에 이르기까지 혁신적인 방법과 전략 전술로 적을 격멸한 사례들은 비대칭전의 사례로 볼 수 있다. 전투에서 승리한 핵심요인에는 비대칭 전략 및 수단의 차별적 우월성이 반드시 존재했고 앞으로도 이러한 현상은 지속될 것이다. 한 때 창출된 비대칭은 시간이 경과함에 따라 상대편이 모방적으로 적응하여 비대칭이 소멸된다. 현대전에서 전략적 전술적 비대칭의 우위를 확보하려면 새로운 비대칭 전에 대하여 연구하고 상대방의 전략과 전술에 대응하는 방책개발을 계속해야 한다. We can not respond asymmetric warfare effectively. The asymmetric operation is performed in asymmetric methods and means with different characteristics and functions to their enemy. And the character of the asymmetric operation have 'heterogeneity' and 'superiority' in principle. The type of asymmetric strategy is complex and diverse. Since we can classify the type of the asymmetric strategy in many different way and we must study in many ways and aspects. When we study asymmetric war previous cases from modern to ancient era, we can find that the key factors of the victory have superiority of the asymmetric strategy and discriminatory measures. The asymmetry is created when one party has to adapt to the strategic environment. If we want to secure a strategic advantage, we must take a number of case studies and countermeasures for asymmetric warfare.

The synthesis of epichlorohydrin was carried out by the epoxidation of allyl chloride with tert-butyl hydroperoxide(TBHP) over silica supported molybdenum catalyst. Kinetic study was performed at $60-80^{\circ}C$ and 10 atm with the molar ratio of TBHP/Allyl chloride between 0.01 and 0.1 in a batch reactor. The epoxidation of allyl chloride was inhibited by tert-butyl alcohol and kinetic data could be represented by Michaelis-Meten type rate equation. The reaction mechanism could be explained by the combination of reversible adsorption of TBHP and tert-butyl alcohol accompanied by reaction of allyl chloride with TBHP adsorbed on $Mo/SiO_2$ catalyst. t-Butyl hydroperoxide(TBHP)에 의한 염화알릴의 에폭시화에 의해서 에피클로로히드린을 합성하는데 실리카에 담지된 몰리브데늄 촉매를 사용하였다. 속도론적 연구는 회분 반응기를 사용하여 $60-80^{\circ}C$, 10기압에서 TBHP/염화알릴의 농도비를 0.01-0.1의 범위내에서 수행하였다. t-butyl alcohol(TBA)에 의해서 염화알릴의 에폭시화 반응이 억제되었고, 반응속도는 Michaelis-Menten 형태의 속도식으로 표현할 수 있었다. 반응기구는 TBHP와 TBA의 가역흡착과 $Mo/SiO_2$에 흡착된 TBHP와 염화알릴의 표면반응으로 설명할 수 있었다.

All architectures in the history have certain attitudes of aesthetic expression of their own. Depending on the culture, such aesthetic attitudes are not the same but different. This paper aims to identify the nature of the difference of aesthetic attitude in the architectures of the East and the West. As a way of approach for this purpose, two keywords are employed as representative concept. They are: 'proportion' and 'vitality'. Proportion, of course, represent the attitude of the Western, while, vitality, the Eastern. Although these two words are subjective selection, it is hoped that the nature of aesthetic attitudes could be observed through the windows of these two representative concepts. We all know that the architects and students of architecture of this period, are very much concerned about the aesthetic expression of their design. However, the value judgement of aesthetic quality seems quite confused in modem period. If the nature of aesthetic attitudes of the Eastern and the Western architecture is well understood, such understanding will help much for the direction of architectural aesthetic of future architecture.

미국의 패권전략과 한국 군사전략 발전방향

This thesis is to make an appropriate national defense policy of Republic of Korea through studying the Hegemony Strategy of United States. I searched the theory of hegemony. The hegemony was differently defined by the point of time and region. The strong power nations with the hegemony have been making efforts to maintain their hegemony everytime. I have conclusion that the presence of hegemony once emerged, it brought regional stability in place whether it is coercive or beneficial. The stability and instability of international order IS not exclusively dependent on hegemony. Even if the safety of hegemony cannot guarantee absolute stability of international order, there IS on doubt that the hegemony has enormous impact on that. According to the hegemonic theory, the history of mankind equals to the history of rising and falling hegemony. The international order was changed as the hegemony changes. The United States has been making efforts to maintain her global hegemony during the post cold-war era as well. Taking all these into consideration, relevant military strategy direction able to pursue national interest is that to make up for the relative weakness in the strategic environment. South Korea have to prepare security policy response as following. First, South Korea should build the military force equipped with advanced weapons in military technology sector and solidify military diplomatic relation able to form cooperative relation in wartime. Second, South Korea should make solid Alliance of Korea and U.S. Third, develop and maintain multilateral security cooperation of East Asia. Forth, we could realize that there are means that can neutralize opponent's strong point by seeking one or two and more asymmetry in the aspect of strategy, tactics, and means through asymmetric strategy. Than the military force of South Korea should develop into a force that is able to overcome to the traditional North Korea's threat and new type of conflicts. And the force should have sufficient strength and be deployed to effectively defend the Korean Peninsula. So, we need to establish a denial and defense system against any hostile neighboring country. Therefore, ROK military forces preparing for the future should try to construct a future military power to gradually establish enough strength for self-defense to prepare for a uncertain security environment and when the Korean Peninsula is unified in a future.

Historical study of Korean traditional houses have been carried, mainly, based on the geographical region of Korean peninsula. However, the case of primitive houses can not be researched according to the geographical and racial concept of modern nations. This study aims to examine the primitive houses of ethnic minorities of northeastern China, where the cultural and racial background have been deeply rooted in the history of Korea as well as Korean traditional houses. Through the field research and literary materials, the basic types of primitive houses of the five ethnic minorities could be identified. Among these types, those that have possible relationship with Korean houses, are cone shaped house, underground house, and elevated wooden house. Archeological evidences of underground houses were amply found in Korea already, but above ground evidences could not be found. However, It seems quite certain that the cone shaped houses and elevated wooden houses, too, existed in Korea as one of the earliest housing types, as can be examined in remaining examples in Korean peninsula. With no doubt, the primitive houses of Korea have strong connection with that of the ethnic minorities of northeastern China. This can be verified through the facts that the evidences of cone shaped houses, the similarities of the use of Inner space, the evidences of elevated wooden houses. Also, the combination of wooden floor and ondol, which is known to be one of the strongest characteristic of Korean traditional houses, could be originated from the combination of primitive summer house, the elevated wooden house, and the winter house, the underground house with ondol.

동서양 건축에서의 공간과 시간

김성우,Kim, Sung-woo 한국건축역사학회 2004 건축역사연구 Vol.13 No.3

The tradition of architecture in the East and the West are different in many ways. One of the basic cause of such difference, however, is the different ways of perception of space and time. This paper aims to identify the attitude of perception of space and time in the cultures of the East and the West, and its influence on architecture. Degrees of importance placed on either space or time, as well as the modes of perception of space and time are discussed in relation to architecture. Basically, the architecture of the West seems to be more spatially oriented than the East, and this have much to do with the fact that the tradition of Western architecture is visually oriented. On the other hand, East Asian architecture have been more conscious on bodily feeling and its movement in architecture. Spatial units of traditional Eastern architecture, are arranged in such a way in which man can experience the change of space that is supposed to be organized to form a sequential message. Thus, in the East, temporal dimension is more deliberately included in the course of architectural experience compared to the cases of the West. Although it is not easy to attempt any kind of value judgment on such aspects, it is necessary to understand how the different perception of space and time influenced architectural outcome, especially when one wants to understand the cultural cause that have made the architectures of the East and the West very different. Such understanding is particularly important in East Asia where their future of architecture depends much on how they harmonize the Eastern and Western background which are already built up as two cultural structure in their consciousness to be able to create more desirable architecture for themselves.
