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.

19세기 초반 노상추(盧尙樞)의 백운동 별업(別業) 조성과 경영

The subject of this article is a historical figure, Roh Sang-chu (1746-1829). After ending his 28-year-long bureaucratic career as the associate commander at Gadeuk Naval Fort in 1813, he started a typical life of a rural yangban in his home town, Seonsan, Gyeongsang-do province for 17 years until his death in 1829. The most notable feature that involved the latter years of his life at hometown was the creation of the Baeg'un-dong manor ("byeol'eop"). He started creating the manor in 1814 and dedicated himself to developing it as a mean for economic development and social stability of the village, until his death there after a long illness. It is the locale of Baeg'un-dong that this research pays the greatest attention to. It was a border village under the jurisdiction of Dogae-myeon, Seonsan prefecture in the Joseon dynasty. As a border village, it was much closer to Bian prefecture than to Seonsan. For this reason, Baeg'un-dong now belongs to Uiseong County. The fact that it was alienated from the Seonsan prefecture, in spite of its belonging to the prefecture, is the most crucial factor which determined the historical-geographical character of the village. It was for this reason that Roh Sang-chu made efforts to build a shelter for illegitimate descendants there. He had an illegitimate son, Roh Seung-yeop(1796-1842). Roh Seung-yeop and his descendants led a socio-economically stable life under the guardianship of Roh Sang-chu, who acted as a patriarch of the manor. But their stable life began to derail after the death of Roh Sang-chu, due to their disadvantageous social status as 'illegitimates.' In the course of the downfall, the second and third generation of descendants of Roh Seung-yeop had to earn their lives as hired hands or loggers, leading a hard life in a small, secluded area inside Hwa'rim, village for the legitimate descendants of Roh's lineage. It testifies to the fact that the illegitimates were given little opportunities for their social activities during Joseon dynasty. Given this social background of Joseon dynasty, Roh Sang-chu s experimentation to create a manor for the illegitimate descendants had to end with incomplete success.

공간(空間)과 천지(天地) - 동서양 건축에서의 공간관 -

김성우,Kim, Sung-Woo 한국건축역사학회 2005 건축역사연구 Vol.14 No.4

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.

중국의 부상으로 동아시아에서 헤게모니가 중국으로 이동하고 있다는 것은 현실화되었다. 시진핑 정부의 대외정책은 우리나라와 주변국, 전세계에 영향을 직 간접적으로 미치고 있는데 중국이 주창하는 신안보관과 실크로드 정책, 새로운 패러다임의 외교방식을 주장하고 있다. 중국은 아시아에서 새롭게 형성되는 강력한 국가로서 경제력을 이용하여 아시아 질서를 재정립하고 패권을 장악하려는 의도가 명확해지고 있다. 나아가 세계 패권에도 미국과 쌍두마차로 달리고자 하는 의도가 정치, 경제, 군사 및 외교 분야에서 나타나고 있다. 북한 핵 미사일 개발로 촉발되고 있는 한반도 위기상황을 제대로 극복하기 위해서는 우리는 한 미 일 공조와 나아가서 중국과의 관계 개선에도 최선의 노력을 경주해야 할 시점에 와 있다. 본 연구에서는 북한의 안보위협에 따른 한반도 주변의 역학관계를 벗어나 제2차세계대전 이후 냉전과 탈냉전 시기를 거치면서 중국이 구사해 온 동남아 정책에 대하여 거시적으로 분석하였다. With the rise of China, the power and hegemony is moving to China in East Asia. The foreign policy of the China government is directly or indirectly affecting Korea, neighboring countries and the world. China is advocating a new international policy, a new security system, silk road policy and a new paradigm. China is a newly emerging powerful nation in Asia, and it is clear that China has the economic power to reestablish the Asian order and take over the hegemony. In addition, we want to run the world supremacy with the United States in political, economic, military and diplomatic sectors. In order to overcome the crisis of the Korean peninsula, which is being triggered by North Korea's nuclear and missile development, we are in the position to do our best to cooperate with Korea, the United States and Japan and further improve relations with China. In this study, I analyzed the policy of Southeast Asia and China macroscopically.

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.

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.

The study is about the process of modernization of conventional rural houses in Kyung-gi province. It alms to identify the pattern of change, particularly focusing on the changes of the site plan and plan. The site of study is Samga Village, in YongIn County, near Seoul. The study discusses the process of modernization during the three decades from 1960 to 1980. The basic information was obtained through field research and site analysis, and the study relies predominatly on observational and statistical analysis. Four developmental stages can be clearly identified which are ; (1) Traditional type, (2)Modified-traditional type, (3) Saemaul type, and (4) The type of urban houses. The analysis was done through identification of changing site plan and plan. It is interesting to note that the changes of these elements show a certain pattern of sequential steps which also can be classified according to the four developmental stages mentioned above. The pattern of site design was consistantly maintained while plan and building system became very different However, the process of modernization of Korean rural houses was the process of producing a certain type of architecture that is not universal but uniquely Korean.
