        인공고관절용 스테인리스강 316L에 증착된 다이아몬드상 카본 필름의 전기화학적 특성에 관한 연구

        김호건,안승호,김정구,박세준,이광렬 대한금속재료학회 2004 대한금속·재료학회지 Vol.42 No.4

        Diamond-like carbon (DLC) films have several advantages in applications such as high hardness, chemical inertness, low friction and electrical insulation. Furthermore, DLC-coated STS 316L films have been reported to have a good biocompatibility, such as the absence of inflammatory response. Thus, corrosion resistance is the first consideration for the biomaterials to be used in the body. DLC films have been deposited onto substrates of STB 316L for artificial hip joints using r.f PACVD (plasma-assisted chemical vapor deposition) with C_(6)H_(6) and mixture of C_(6)H_(6) and SiH_(4) as the process gases. Three kinds of DLC-coated films were prepared as a function of diverse bias voltage and Si incorporation. Corrosion behavior of DLC films was investigated by electrochemical techniques (potentiodynamic polarization test and electrochemical impedance spectroscopy) and surface analyses (atomic force microscopy and scanning electron microscopy). The electrolyte used in his test was a 0.89%NaCl solution of pH 7.4 at temperature 37℃. Electrochemical measurements showed that DLC films with higher bias voltage and Si incorporation could improve corrosion resistance in the simulated body fluid environment.

        전승교육과정의 실상과 문제점에 관한 일연구 : 공예·기술 분야를 중심으로 On the Traditional Artistic Crafts

        김세건 서울대학교 비교문화연구소 2002 비교문화연구 Vol.8 No.2

        This study intends to analyze the status quo of transmission training and to improve the cultural policy through the point of view of the "man cultural property"They are expected to preserve and educate the traditional artistic craft that is a part of the intangible cultural heritage. Although the korean government has strived to designate and preserve many crafts and arts since 1962 when the cultural property protection law was promulgated, the major parts of traditional artistic crafts are at the point of disappearance because they do not successfully adjust in the new environment of commercialization. The result of study is as such: first, the policy considers intangible culture as the property in the point of view of cultural substantialism. This perspective disregards a proper sociocultural context. The policy has focused on the tangible cultural properties rather than the intangible cultural heritages. Therefore the policy has attached importance to the discovery, designation and preservation of intangible cultural heritage than it's transmission training and promotion enhancement. Second, human cultural properties have been considered as "pensioner"nd do not have played a more significant role to preserve, educate, promote and create traditional culture. Rather they are in the controls and oppressions of government which is an important subject of cultural policy. In this process, both subjects have been suspicious to each other. It is necessary for both to recuperate confident relations for a new environment to promote and create intangible cultural heritages.

        멕시코 농촌에서 꼼빠드라스고의 구조와 역할

        김세건 서울대학교 비교문화연구소 2001 비교문화연구 Vol.7 No.2

        본 연구는 멕시코 한 농촌인 산 안드레스 데 라깔에서 꼼빠드라스고가 어떻게 형성되고, 어떤 구조 및 특징을 지니며, 어떤 역할을 하는지 살펴보자고 한다. 산 안드레스를 비롯한 라틴 아메리카 농촌 지역은 가족 중심의 사회로 공식적인 어떤 친척조직도 형성하지 않는다. 이는 식민지의 산물이다. 즉 가족과 친척을 기본 사회구조로 한 깔뿔리는 정복 과정에서 토지 등의 물적 토대를 상실하였다. 정복이후 가족·친척관계는 개인들간의 관계를 형성하는 가장 중요한 기본 요소로 일상적인 협력관계를 유지하지만 종족과 같은 규범화된 제도와 조직으로 발전하지는 않는다. 이를 보완·대체하는 것이 꼼빠드라스고이다. 꼼빠드라스고는 스페인과 라틴 아메리카의 혼합(mestizaje)의 결과로 사회·문화적 환경과 부딪치면서 형성·변화되어 온 역사적 산물이고, 또한 지금도 변화하고 있다. 식민지 초기의 꼼빠드라스고는 서구의 카톨릭 국가에서처럼 세례, 견진례, 성체, 결혼에서 대부자 관계를 축으로 한 의례적 후원관계가 중심을 이루었다. 그러나 점차 식민지 후반으로 오면서 사람 외에 성상 등을 비롯한 물체들을 꼼빠드라스고 체계에 포함시키면서 대부자 관계보다는 대부모 관계가 중요시되는 라틴 아메리카적 독특성을 획득하기 시작하였다. 꼼빠드라스고는 단순히 원주민 친척관계를 대신하는 의사친척관계의 한 종류에 머물기보다는 친척, 우정, 정치·경제적 연망이 적절하게 포함할 수 없는 새로운 사회 관계망을 형성한다. 결국 꼼빠드라스고는 개인, 가족 나아가 공동체 사이에서 공식적, 의례적, 사회적 관계를 가능하게 하는 통합과 분리의 메커니즘으로 라틴 아메리카 사회와 문화의 핵심인 것이다. This study analyses how the compadrazgo is constructed in daily life in a mexican peasant society, San Andres de la Cal, Morelos. Secondly I will observe characters of the compadrazgo structure and it’s function and role. The social structure of San Andres de la Cal, such as other Latin-American societies, is based on family. Moreover this society does not have formal kinship organizations. The spanish conqueror transformed indigenous societies based upon Calpulli. In this process the traditional kinship relation was weakened and replaced by the system of catholic ritual kinship sponsorship which centered in the padrino-ahijado dyad. The compadrazgo system that we know today is an acculturative complex that has been transformed and created by native people. In the colonialization with the extension of sponsorship to images and material objects, this system began to transcend the padrino-ahijado dyad and increasingly began to shape the compadres-compadres dyad. The compadrazgo is a mechanism of integration and separation that has made possible construction of ritual and social relation. The compadrazgo system is the first distinctive aspect of Latin America social structure.

      • 북(北, el Norte)을 향하여 : 멕시코 농민들의 미국ㆍ캐나다로의 일시 이민과 사회ㆍ문화적 변동의 제양상 The Mexican Peasant's Temporal Migration to the United States or Canada and Aspects of Sociocultural Change

        김세건 서울대학교 사회과학연구원 2000 한국사회과학 Vol.22 No.2

        본 연구는 멕시코 중부에 위치한 모렐로스주(州) 떼뽀스뜰란 무니시삐오의 한 농촌, 산 안드레스 데 라 깔(이하 산 안드레스)에서 일어나는 이민의 정치 · 경제적, 사회 · 문화적 구조에 대하여 고찰을 하고, 이민이 이 사회에 어떠한 영향을 미치는지를 살펴보고자 한다.멕시코 사람들의 미국으로의 이민은 기나긴 역사적 산물로 미국과 멕시코 사이에서의 정치 · 경제적, 사회 · 문화적 상황의 변화를 반영하고 있다.특히 오늘날 멕시코에서 미국으로의 이민은 너무도 보편화된 멕시코인들의 일상생활이하 해도 과언은 아니다.피폐한 농촌 경제와 미국으로의 이민자들의 존재가 어울어진 모습은 멕시코 농촌의 오늘을 가장 잘 드러내준다.결과적으로 이민은 멕시코의 경제 농촌근대화의 결과이자 다른 한편으로는 농촌 근대화 및 변화의 기본 통로로 작용하고 있다. 옥수수 등의 전통적 생계농업과 석회 생산 등에 기반하였던 산 안드레스 사회는 1970 · 80년대에 토마토 재배와 인근 공업단지에서의 임금노도의 확대로 경제적으로 가장 좋은 시절을 구가하였고, 급속토록 시장경제로 편입되었다.그러나 80년대 중 · 후반에 들어 토마토 재배의 쇠퇴와 국내 경제위기에 따른 임금노도의 기회가 감소하면서 산 안드레스 사람들은 다양한 자원을 이용하여 새로운 적응 전략을 형성하였다.일부는 '친숙하면서 위험이 덜한' 옥수수 · 콩 등의 기본 생계 작물의 재배를 통하여 상품시장과의 관계를 유지하고자 하고, 다른 일부는 자신들의 최후의 상품인 노동력 판매를 통해 시장경제에 적응하고자 특히 미국과 캐나다 등지로 이민을 간다.근대화가 야기한 농업위기와 끝날 줄 모르는 국내 경제의 위기는 산 안드레스 사람들의 삶의 위기로 분출되었고, 이 속에서 이들은 결국 합법이든 불법이든 간에 국경을 넘고 있다.다중적 정체성을 지닌 이민자들은 미국에 합법 또는 불법으로 양국경을 넘나들거나 체류하며, 불평등한 정치 · 경제적, 사회 · 문화적 지배구조 속에서 '산 안드레스 데 라 깔리포르니아'와 같은 자신들만의 통국가적 사회공간을 창출하며 미국 사회에 적응해 가고 있다.이민은 개인, 가족 그리고 지역사회가 경제 및 삶의 위기에서 생존하기 위한 중요한 출구였음에는 틀림없다.그럼에도 불구하고 이민은 자신들의 사회를 세계의 정치 · 경제적, 사회 · 문화적 구조로 급속히 통합 · 종속시켜 왔다.결과적으로 산 안드레스는 생산활동과는 거리가 멀어지고, 단지 미국 또는 캐나다의 노동 시장을 위한 노동력의 공급자가 되어가고 있다.이에 따라 생산활동을 중심으로 한 사회 · 문화적 관계에 기반하여 유지되던 기존의 공동체는 생산활동의 저하, 가족관계 약화 및 마을 사회 구조 및 정체성의 약화 등으로 끊임없이 변화 · 해체되어 가고 있다. This study analyzes the temporal migration of Mexican peasants to the United States and Canada through the ethnographic data collected in a Mexican peasant's community, San Andrew de la Cal, Tepoztlan, Morelos. Studying temporal migration, this paper focuses not only on the socio-economic reason of temporal migration and sociocultural structure of peasant's community but also on the sociocultural change of the peasant's community in which the temporal migration brings. The Mexican migration to U.S. has long historical background and patterns representing changes of political, economical, and sociocultural relations between Mexico and the United States. Specialty now it is not exaggerated to argue that the migration to U.S. is a generalized daily life of mexicans. The temporal migration itself express the impoverished Mexican rural economy and societies. The migration is a result of rural modernization of Mexico, on the other hand, it is a promotive channel of rural modernization and change. Before 1970s, maize and lime had been the main products in San Andres de la Cal. With the introduction of tomato and participation of labor market in the industry zone since 1970s, this community joined regional market economy and brought economic wealth. But in the latter half of the 1980's, the people of san Andres de la Cal have had to cope with the new situations provoked by the decline of tomato production and job opportunity. Some * Investigator, The Institute For Cross-Cultural Studies, Seoul National University. Research Area: Environmental problems, Mexican peasants societies. Major Publication: El cambio, sus caracteristicas y el ecosistema en un pueblo campesino mexican, "Antropologia y medio ambient:(2000), Aprender-comprender la antropologia, Mexico. E-mail: amoramor@kornet.net people responded to this situation back in the traditional agriculture which mainly cultivates maize and bean. It was the most intimate and secure strategy. On the other hand, some people decided to go U.S. and Canada to survive by selling their labour, the only commodity that they had. The national economic crisis has impelled people of this community to cross the border legally or illegally. To survive in the new social world, the migrants need to develop various adaptive strategies. Creating multiple identities and inventing transnational social spaces touch as San Andres de la California are the examples of survival strategies. During the economic crisis of this peasant's community, the temporal migration has played an important role for individuals, families and regional society itself to survive. Nevertheless, the migration forces this community to incorporate and subordinate to econo-political and sociocultural structure of the world. San Andres de la Cal is going to be separated from the productive activities and to be converted into a supplying base of the cheap labor power for the United States and Canada. As the result, this community that had been sustained by sociocultural relations established in the process of productive activities, is in the process of rapid change such as dissolution of family structure and traditional relations and reduction of agricultural production. It leads to the loose solidarity and identity of community.

      • 「위대한 신브라운」(The Great God Brown) : 신의 부재

        김세웅,최진근 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.3 No.2(A)

        Eugene O'Neill's object of self-exploration is to achieve a better understanding of man's inner life. He searches for "something" which oppresses and controls the psychological realities of human life. O'Neill defines "something" as "the Force behind- Fate, God, our biological past creating our present, whatever one calls it- Mystery certainly." the very mysterious, inscrutable Forces behind human life make O'Neill express himself in art. The characters in the middle play, The Great God Brown, positively struggle against the Force to overcome it. They try to achieve self-realization through the pursuit of a new god to give meaning to human existence and to comfort the fear of death. O'Neill suggests that man's blind pursuit of a material life in a capitalist society makes him dehumanized. Man is alienated by the god of science and materialism made by himself. His blind pursuit of the material life results in his spiritual corruption. O'Neill severely criticizes the established religions and a capitalist society, and seeks for his new god within man's inner self and purity.

        Recently, as many next-generation appliances are become digital and intelligent, companies have come out various networked appliances to communicate with each other though home network. It will be expensive and difficult to apply new technologies using real appliances for verifying application services. Therefore, a home network testbed, which is consisted of simulator and emulator for verifying interworking services of various information appliances, is needed to reduce design cost and time. In this paper, a home network testbed is implemented and designed to support interworking services of home network. The devices in the testbed are designed with modular components for reusability, and the components are invoked through XML message. The correctness and effectiveness of the testbed is verified through interworking services on various components.

        임동건,정세민,최유신,김도영,이준신 성균관대학교 1997 학술회의지원논문목록집 Vol.1997 No.-

        We have investigated Pt and RuO₂as a bottom electrode for a device application of PZT thin film. The bottom electrodes were prepared by using an RF magnetron sputtering method. We studied some of the property influencing factors such as substrate temperature, gas flow ratem and RF power. An oxygen partial pressure from 0 to 50% was investigated. The results show that only Ru metal was grown without supplying any ‬O₂gas. Both Ru and RuO₂phases were formed for ‬O₂partial pressure between 10-40%. A pure RuO₂phasewas obtained with ‬O₂partial pressure of 50%. A substrate temperature from room temperature to 400°C was investigated with XRD for the film crystallinity examination. The substrate temperature influenced the surface morphology and the resistivity of Pt and RuO₂ as well as the film crystal structure. From the various considerations, we recommend the substrate temperature of 300°C for the bottom electrode growth. Because PZT film growth on top of bottom electrode requires a temperature process higher than 500°C, bottom electrode properties were investigated as a functiona of post anneal temperature. As post anneal temperature was increasedm the resistibity of Pt and RuO₂was decreased. However, almost no change was observed in resistibity for an anneal temperature higher than 700°C . From the studies on resistivity and surface morphology, we recommend a post anneal temperature less than 600°C.

        Talus tuberculosis is a rare disease, even in an endemic tuberculosis area. In reviews of the worldwide literature, only 18 cases of talus tuberculosis have been reported. Recently, we experienced a case of a 70-year-old polycythemia vera patient with right metatarsopharyngeal joint pain for 2 months duration who was diagnosed with talus tuberculosis with prostate involvement. Tuberculosis should be considered as one of the causes of monoarticulitis, especially in countries, where the disease is endemic. Additionally, we highly recommend taking a biopsy of the site of suspected infection because an early diagnosis is the key to successful treatment.
