인류가 위성을 발사하기 시작하면서 수많은 우주파편이 발생하게 되었고 이로 인하여 우주파편 환경은 날이 갈수록 심각해지고 있다. 우주공간을 비행하는 우주물체는 분쇄된 파편, 임무 관련 파편, rocket body 그리고 운용위성으로 구분된다. U.S. Space Surveillance Network에 따르면 10cm 이상 크기를 갖는 물체는 현재 13,000개가 넘는다고 알려지고 있고 질량만 해도 6,000톤이 넘는다. 이런 우주파편 환경으로 인하여 우주파편 간의 충돌, 우주파편과 운용위성 간의 충돌 또는 운용위성 간의 충돌에 대한 우려가 꾸준히 제기되어왔고, 불행하게도 2009년 2월 10일 Iridium 33과 Cosmos 2251 위성이 고도 790km 부근에서 충돌하여 1,300여개의 우주파편이 발생했다. 또한 2007년에 중국이 고도 860km 부근에서 750kg에 해당하는 자국의 위성(FY-1C)을 미사일로 격추시킴에 따라 2500여개의 우주파편이 발생하여 저궤도의 우주파편 환경을 더욱 심각하게 만들고 있다. 운용위성과 우주파편과의 충돌 가능성을 분석하기 위해서는 우주파편 및 위성의 궤도정보를 알아야 한다. 이를 위해서 NORAD(North American Aerospace Defense Command)에서 제공하는 TLE(Two Line Element)가 주로 이용된다. 하지만 관측 및 궤도 결정 특성상 수 km의 오차를 포함하므로 궤도정보의 공분산이 크다는 단점이 있으므로 충돌 분석을 수행하는데 있어 한계가 있다. 이 논문은 충돌분석 수행에 있어 TLE 정보만을 이용한 경우뿐만 아니라 정밀궤도와 TLE를 동시에 이용한 경우를 비교함으로써 충돌 불확실성의 해소방안을 제시할 계획이다.

Changes in land cover or land use, such as changes in forest area, can cause changes in water and energy circulation, ultimately affecting overall hydrological cycle including stream flow, evapotranspiration, soil moisture, and base flow. In this study, the changes of the hydrological processes over the past long period were simulated by using large-scale surface hydrologic model along with various soil, land use, vegetation, and meteorological data. For this purpose, this study simulated and evaluated the changes in the hydrological cycle for the past 50 years (1955-2010) in East Asia including China, Japan and South Korea. In particular, this study used the land cover maps which can properly reflect the vegetation condition for each simulation period. As results, the mean runoff ratio of China was estimated to be 47.0% over the entiree period, 62.7% in Japan and 49.4% in South Korea. The mean soil moisture of China was estimated to be 22.2%, 35.6% in Japan and 23.9% in South Korea. Finally, the mean evapotranspiration rate was estimated to be 52.7% in China, 37.3% in Japan and 50.4% in South Korea. Especially, in China, the hydrological cycle was found to be changed very much for the entire simulation period. However, in Japan, the hydrological cycle was found to be very stable for the entire simulation period. The hydrological cycle was also found to become stable mainly due to the stabilization of the vegetation.

This paper aims to explore the characteristics of regional network of Korean firms in Dalian City, China, which is focused on social, cultural and institutional characteristics. To achieve this goal, the paper attempts to analyze the supply of raw material and parts, sales and cooperative relations of the firms. Among Korean firms in Dalian City, the characteristic of non-local network can be seen in supply enterprise of raw material, parts and semi products. On the other hand, a tighter local network relationship can be seen in sales. Large companies appear stronger in non-local network than small businesses and small businesses are stronger in local network. In terms of cooperation among enterprises, many firms have networks of joint marketing, joint use of equipments, exchange of techniques and information with the supply enterprise. With the customer enterprise, there is a network in joint marketing and manpower training. Especially, most of the customer enterprises are Chinese ones, which have extensive networks in big cities, such as in Beijing, Shanghai, Guangzhou, Tianjin and Dalian. In local network, the Korean firms in Dalian cooperate in product development, finance and manpower training with local firms. And in non-local cooperation, Korean firms are active in tech support, information exchange and R&D.

We considered the historical significance and the individual aspects of heroes that are reflected in the historical differences between men and women expressed in the old tales. To achieve this purpose, the paper selects , , , , and as text. Their characters were then catalogued into cultural heroes-Choi ChI-won, popular heroes-Jeon Woo-chI, family heroes-Chung So-jeo, pro-Japanese enlightenment hero-Ilneyomhong and Lee Hyung-kyung. He also tried to achieve his goal by describing the historical significance of the hero's type. China and Joseon were at odds with each other, so their relationship was uncomfortable. It is at the forefront of that concerns this issue. As he was a great writer of Silla, he was able to play a leading role with Chinese writers. We needed Choi ChI-won, a cultural hero, to express our pride that Joseon has a superior culture than China. Joseon was a Confucian society with a strong anti-semitic system. Accordingly, the people were persecuted by the aristocrats for all their centers, and this required a folk hero. He is the leader of the war. Jeon Woo-chI is a real folk hero who solves the people's grudge and wishes through doctoring. As women go back to the late Joseon Dynasty, they change the way women treat men after experiencing war. For this reason, there are novels about female heroes such as <江都夢遊錄>, <朴氏傳>, and <李學士傳>. I think the writer given hope to women who are upset by incompetent men even in their work at the time. Jeongsojeo is a leading hero in the family who is more active than the female lead who is faithful to old wives, but is responsible for helping her husband. Joseon goes through the 淸日 and 露日 wars and is at the center of Japan's prosperity. Japan is the Japan-Korea Treaty of 1905 after the Japanese Resident-General of Korea after heavy emphasis put on with the politics. At this time, he published pro-Japanese newspapers and published pro-Japanese novels to highlight pro-Japanese collaborators. It is Ilneyomhong and Yeoyongwoong.

As the number of foreigners who stay for a long time increases, their residential concentrations have emerged and developed. This research aims at investigating how and why immigrants' residential concentration sustains and develops. In order to understand the roles of the residential concentration for the immigrants' everyday, we used the framework of grunddaseins funktionen including residence, labor, shopping, education, leisure, commuting, and community activity. Accompanied is a case study of Daelim-dong which is the largest Chinese concentrations. The result shows that combined with co-ethnic preference in residence, various amenities at the concentrations attract new immigrants and hold existing immigrants, allowing the concentrations sustain and develop. It has been pointed out that there are the difference factors that foreign immigrants concentrate residentially: 'co-ethnic residential preference' for immigrants from more developed countries and 'discrimination' for immigrants from less developed countries. However this study shows that the residential concentrations for less-developed-country-immigrants could maintain and develop with grunddaseins funktionen based on co-ethnicity.

In the 2000s, China has been pushing the issue of San-Nong as a national priority. Farmland transfer, one of the solutions to the problem of San-Nong, has grown rapidly over the past decade. Especially, as farmland transfer was promoted, the rural economy developed and the living standards of the farmers improved greatly. However, the rigidity of farmland transfer type, which focuses on Zhuan-Bao method, hinders farmers' willingness to relocate to farmland transfer and ultimately acts as an obstacle in promoting massive farmland transfer. The purpose of this paper is to analyze the determinants of farmland transfer types and farmland transfer prices in Chinese farmers. Based on the results of the analysis, the following implications are suggested. First, farmers should be instructed to farmland transfer in a Ru-Gu manner; Second, the contract period must be long; Third, it is necessary to prepare countermeasures for the farmland transfer by crops; Fourth, Educational programs should be built for the farmers of farmland transfer.

The purpose of this thesis is to look through the political and social background of China preparing for a new era after getting out of the Communist Party of Mao Zedong, rapid inflow of the Western modernism and the avant-garde art arising in China with the focus of art works of Xu Bing, which contributed to the expansion of printmaking of China. Particularly, 85 New Wave Movement arose by young artists since 1985 and the China/Avant-Garde Exhibition held in Beijing in 1989 are the two important issues which reflect a new change from the traditional Chinese art. The artists of 85 New Wave Movement, who pursued a historical revolution and novelty, worked very actively by leading private exhibitions. Since the Cultural Revolution, the government owned the National Museum of Fine Art Beijing had exhibitions on a large scale displaying various visual arts such as performing art, installation, painting, sculpture but the Chinese government interrupted exhibitions two time due to bold performing art and unconcealed installation. Some artists were even taken to the police when performing art. Under these circumstances, Xu Bing, who majored printmaking, produced one of his major works, Books from the sky(1988), while he was working on various experiments focusing on the production process of printmaking and its repetitiveness. Xu Bing devised letters, carved them in trees and finally created approximately 2000 characters. Going further he displayed it as installation work, which means the developed characters go beyond a printed form, for audiences. This made him earn favorable reviews since it was a form of western art coupled with Chinese contents 'Chinese character'. After he received unfavorable reviews, however, he went to America leaving his last work in China, Ghost Pounding the Wall, in 1990, which was not able to exhibited. In those days, China society was going through a chaotic era thanks to the extinction of the Cultural Revolution and Deng Xiaoping's(1904-1997) reformation after the debacle of Tiananmen Massacre. This study looks into Xu Bing's artworks from his initial print works until he went to the US in 1991 and examines how he performed experiments utilizing reproductivity and plurality of prints tinged with Chinese traditional elements, and ultimately became one of the avant-garde artists representing the period.
