The avionics system architecture considering the domestic inexperience of the IMA system architecture are suggested for the Next-generation Corps Unmanned Aircraft System.

19세기 초반 노상추(盧尙樞)의 백운동 별업(別業) 조성과 경영

김성우(Kim Sung-woo) 한국역사연구회 2010 역사와 현실 Vol.- No.78

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.

입자(粒子)와 장(場) : 동서양 건축에서의 단위개념

김성우,Kim, Sung-Woo 한국건축역사학회 2005 건축역사연구 Vol.14 No.1

All architecture in the history were based on a certain concept of architectural unit that functioned as a base model of architectural design. As we know, such model was not the same in the East and the West, and therefore, their architectures are not the same. This paper aims to identify how and why such base model of the two cultural area are different. As one way of discussing this issue, the concept of particle and field, as two representative idea of the West and East respectively, the employed. This kind of discussion can not follow the way of scientific verification as method of argument. However, the understanding of such concept of unit model is crucial for the understanding of the architecture of the culture in general. In basic sense, the tradition of Western architecture is rooted in the model of particle, where, architecture is conceived to be as a independent unit standing on earth as if it is a box like object. While, the tradition of Eastern architecture is rooted in the model field, where, architecture is conceived to be a part of field organization. In present days, we are used to the model of particle as if it is the only possible model of architecture. But, in fact, what man need to achieve in their architecture and city, is the balance between the two models.

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.

북한의 대외정책 기조와 전망

김성우,Kim, Sung Woo 한국융합보안학회 2014 융합보안 논문지 Vol.14 No.6

한반도는 탈냉전이라는 역사적 변화에도 불구하고 냉전적 구조가 해제되지 않고 북한의 대남도발은 계속되고 있다. 북한의 천안함 폭침과 연평도 포격도발은 파국적인 남북관계 초래와 동북아 불안정의 요인으로 작용하고 있다. 북한의 도발은 미국과 한국 및 북한 내부 요인이 북한의 의사결정체계에서 복합적으로 작용하여 군사 비군사적 수단에 의해 자행되고 있다. 북한은 한반도의 적화통일이라는 전략기조을 유지하기 때문에 공세적으로 지속될 수밖에 없을 것이다. 북한의 대외정책은 지속성과 상황에 따라 변화하는 양면성을 지니고 있다. 북한 대외정책의 목표와 이념은 비교적 일관성 있게 지속하고 있지만, 정책전개의 전략 전술과 행동 유형에서는 상당한 변화가 있다. 즉, 지속성은 곧 국가 체제유지와 국가 생존 명분의 문제이며, 변화는 지속성과 명분을 유지시키고 발전하기 위한 전술적 종속개념에 해당한다. 합리적인 시각으로 본다면 북한의 대외정책 기조는 군사력과 핵무기 개발을 생존수단으로 삼아 긴장을 조성하여 외교적, 경제적 보상을 얻는 외교방식을 과감하게 탈피하여야 하며 국제사회에 참여하여 하나의 국가로서 국제관례를 지키는 자세를 견지해야 하나 여러 가지 여건상 기존 대외정책 방향을 고수하고 있다. Even though the historical changes of the Cold War, they does not release the Cold War structure in Korean peninsula. And continues North Korea's provocations against South Korea. A factor of instability in Northeast Asia is the causing catastrophic inter-Korean relations and North Korea's Yeonpyeong shelling and provocation of the Cheonan battleship sinking by an explosion. These behaviors have been committed by among the North Korea military. North Korea's provocations made by a complex decision-making system in the United States and North Korea and South Korea. North Korea's aggressive military actions are conducted under the North Korean political system of strategies unification of the Korean peninsula. It has a duality of continuity and change, depending on the situation of a foreign policy in North Korea. If North Korea want maintain structure of their country, they should change the national policy and strategy, tactics and the military action type. North Korea should be a member of international community. As one of the country in the world, North Korea create economic power, nuclear tensions break, and participate in the international community for the peace.

중국의 대 아시아 정책

김성우,Kim, Sung Woo 한국융합보안학회 2017 융합보안 논문지 Vol.17 No.4

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.

Mo / SiO2 촉매상에서 t - Butyl hydroperoxide 에 의한 염화알릴의 에폭시화반응에 관한 속도론적 연구

김성우,박대원,정종식,박대철 ( Sung Woo Kim,Dae Won Park,Jong Shik Chung,Dae Chul Park ) 한국공업화학회 1992 공업화학 Vol.3 No.4

t-Butyl hydroperoxide(TBHP)에 의한 염화알릴의 에폭시화에 의해서 에피클로로히드린을 합성하는데 실리카에 담지된 몰리브데늄 촉매를 사용하였다. 속도론적 연구는 회분 반응기를 사용하여 60-80℃, 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_2에 흡착된 TBHP와 염화알릴의 표면반응으로 설명할 수 있었다. 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℃ 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.
