Coal Gasification Technology is one of the best alternatives among clean fossil fuel utilization. Major technology holding companies are devoting their efforts to develop more advanced technology to dominate the market in advance because of its importance on the applications such as IGCC, CTL, coal to SNG, various chemicals and so on. Japan and China, as well as America and European countries, have developed couple of thousands ton/day-class coal gasification technology. However, our gasification technology remains in the development stage with couple of ton/day-class pilot plant. So, we should be interested in developing this technology considering that we are heavily dependent of coal energy. In this paper, we summarized the trend and status of coal gasification technology development and commercial deployment of major technology holding companies mainly from the presentation materials of 'Gasification Technology Conference 2010', which is the biggest place of information exchange for recent coal gasification technology.

서구 과학의 역사에서 그러하였듯이 국내에서도 비단 '황우석 사태'만이 아니라 크고 작은 과학부정행위 사건들이 이미 발생했고 또 앞으로도 발생할 것이라고 보는 것이 현실적인 판단으로 생각된다. 따라서 '황우석 사태' 2주년이 지난 지금 요청되는 일은 과학부정행위 일반의 원인에 대한 좀 더 체계적인 이해를 통하여 이를 예방할 수 있는 길을 모색하는 것이라 할 수 있다. 이 글은 바로 이러한 문제의식 위에서 과학 부정행위의 원인과 처방에 대한 이론화를 모색하려는 시도의 하나다. 이 글에서는 과학부정행위가 외적 보상이 지배하는 과학자사회의 보상체계와 경쟁구조에 그 근본적 원인이 있다고 진단한다. 또한 최근 전개된 '과학의 상업화'는 외적 보상에 대한 과학자간 경쟁을 훨씬 강화하는 동시에 과학자사회 내의 아노미와 소외 착취를 심화시켜 결국 과학부정행위의 증대를 초래하는 요인이 되고 있다고 분석한다.

본격적인 디지털 방송 시대를 앞두고 대형 TV 스크린에 대한 기술 개발 경쟁이 치열하게 전개되고 있다. 대형 디스플레이 소자로서 대표 주자인 Plasma Display Panel(PDP)의 양산에 한국, 일본 및 대만의 전자 업체들의 경쟁이 시작되었고, 이제는 30 인치 이상 대형 디스플레이로 상업화 가능성이 없었던 TFT(Thin Film Transistor) LCD(Liquid Crystal Display)가 40인치 이상의 TV 시장을 공략하기 위해서 대규모의 투자를 진행하고 있어서 PDP의 아성을 위협하기 시작했다〔1〕∼〔3〕.

This paper examines major activities of Thomas Edison as an example to liberal education for engineers using researches in the history of technology. Edison, as a system builder, developed almost everything necessary to use electric light in the aspects of technology and management. On the contrary, Edison took a conservative stance to new alternating current technology in the case of current war. Edison developed phonograph and motion pictures but didn't understand the meaning of mass culture grown up based on his inventions. This study not only provides an illustrative content to the liberal education for engineers, but also helps to grope for the dynamic character of technological innovation and the desirable features of engineers.

Nylon 6 섬유는 우수한 기계적 물성과(강성, 탄성회복률 등) 염색성 등의 장점을 가지고 있어 의류용 등의 다양한 용도로 활용되어 왔다. Nylon 6 섬유를 포함한 대부분의 합성섬유는 천연섬유인 cotton 대비 흡수성이 낮고, cotton은 흡수성은 탁월하나 수분 건조속도가 매우 느리고 가격이 고가(약 10$/kg)여서 이를 대체할 새로운 고쾌적성 의류용 nylon 합성섬유의 개발이 시도되고 있다. 1953년 최초로 합성이 보고된 nylon 4는 구조상 소수성 탄소수가 적으며 친수성 아마이드기가 상대적으로 많아 흡수성과 속건성이 탁월한 이점을 가짐으로써 면을 대체할 수 있는 꿈의 합성섬유로 인식되었다. 1980년대 Chevron Research사를 중심으로 활발한 사업화 연구가 진행되었지만, 녹는점 $265^{\circ}C$) 대비 낮은 열분해온도($260^{\circ}C$) 특성으로 방사가공 시 내열성 문제를 극복하지 못해 아직까지 상업화에 이르지는 못하고 있다. 최근, 일본 산업기술종합연구소(AIST)를 중심으로 다시 바이오매스 유래 nylon 4의 개발이 시도됨에 따라 의류용 용도전개에 있어 가격 경쟁력을 갖춘 획기적인 소재 전환이 기대되고 있으며, 이로 인해 nylon 4 중합 연구가 다시 전 세계적 주목을 받기 시작하였다. 국내에서도 최근 nylon 4의 방사 내열성을 극복하고 기능성 부여가 가능한 nylon 4 공중합물에 대한 대체 연구가 본격적으로 진행 중에 있다. 본 연구에서는 현재 국내에서 진행 중인 nylon 4 공중합 섬유의 연구동향과 함께 nylon 6 대비 물성 및 염색특성 차이를 비교함으로써 향후 산업화에 기초 자료로 활용하고자 한다.

This study intends to find the meaning of signs' configuration in Korean and British school uniform advertisements, to investigate through reproduction of such signs what influences on students' identity issues are, and to discover the cultural significance of the both nations by analysing sexuality discourses around these ads. The authors apply semiotic analysis methods such as two-stage meaning structure and critical discourse analysis. The research subjects are School uniform advertisements of both in South Korea and in the UK. Through this study, women objectification, the power imbalances between men and women, and child erotica were revealed, and also the uniforms of the meaning and value turned out to be distorted. In addition, on the basis of critical discourse analysis, two nations' school uniform ads, which heavily focused on sexual objectification and commercialism, transformed aspects of unusual esthetic value, reminded of Lolita fantasy, implied wrong justification of deviant sexual orientation, and, caused Korean and British students the confusion of sexual identity and values.

The purpose of this study is to examine how he successfully connected his ideas of fashion design for art with the commerciality without a conflict about for 40 years. It is expected that this study will be a precedent in the aspect of the symmetry between artistry and commercialization in Issey Miyake's works. We will examine Issey Miyake's idea of fashion design and its development for the commercialization since 1970s that he started to give shape to his ideas in the fashion works to exactly commercialize in the market. 1. Re-creation of tradition(a piece of cloth): throughout the 1970s, Miyake continued to experiment with a variety of Eastern design elements. The elements of Japanese or oriental tradition made him to be at the very center of supreme of the world of fashion. He took advantages of his identity, and developed the tradition for mass produce. 2. Design for mass(Pleats Please): Miyake decided to make clothes for the people, not only for the top class of the society. This thought developed the designs for the mass, which were functional, universal for the modem buyer, and accessible to a wide market. He realized his ideal by the medium of pleats, which were made through industrial processes, while he tried variously the aspect of formative of the pleats in the collections. His designs concept is summarized by the industrial product design and anonymous design. 3. Innovation of manufacturing system(A-POC): Miyake in 1999 developed A-POC. A-POC is used modern computers in conjunction with traditional technology. A-POC does not make only a new cloth but also makes a new manufacturing system of clothes.

Recently, governance of science and technology emerged as one of most important social problems and as a result it is crucial to understand it in science and technology studies. This article discusses three most important realms in science and technology goverance - research and development, regulation, and social movement - in the concrete Korean contexts. First of all, the Korean state has driven research and development and promoted its commercialization unlike other developed countries. Consequently, this nationalistic view on science disseminated to Korean public and it generated uniformity in research style and organization. Second, science and technology regulations embraced developed countries' policies, leading to its glocalization. As a result, technocratic old governance and new governance including precautionary principle and participatory democracy coexist. Third, the civil society has challenged expertise and state-driven science and technology governance and fueled social movements related to environment, safety, and health issues. The politics of knowledge created by citizens' voluntary participation and collaborative experts made it clear that science and technology should be no longer tool for economic development. In conclusion, we discuss characteristics of science and technology governance in Korea, giving various implication on current research and policy.
