The study was aimed at developing a power transmission coupling that is possible to transfer power without any trouble even if the two rotating shafts are making minute misalignment. The coupling that has been developed is Flange Flexible Urethane-key Coupling that connects two shafts by flanges with Urethane-key. A model coupling for use in transmitting power of 10hp was made and undergone performance evaluation and tests. Property and usefulness was proved through the test. The performance evaluation has demonstrated a property of $11.25Kgf{\cdot}m$ of allowable torque and 28.25hp of power at 1,80Orpm, which was found to be superior compared to the performance of similar couplings. Based on the performance test, study was made also for improving the shape of the Urethane-key and was successful to make the flange in smaller outside diameter. Further application test at site has proved that the product is easy to install and maintain, and has property of absorbing minute misalignment between two shafts and vibration caused there from.

1990년대 초반 분당, 일산 등 5개의 수도권 1기 신도시가 개발되었다. 이들 신도시는 체계적인 도시계획과 쾌적한 주거환경으로 선호도가 높아 살고 싶은 도시로 인식되고 있다. 이들 신도시 인근에는 중소규모의 택지개발이 많이 진행되었으며, 동일 생활권을 형성하기도 하는데 이들 지역은 '신개발 밀집지역'이라 불릴 수 있다. 수도권에서 이처럼 신개발이 집적된 대표적인 지역이 경부고속도로축에 입지한 분당과 용인서북부 지역이다. 이 지역은 2005년 현재 거주인구가 100만을 상회하는 대규모 생활권을 형성하고 있다. 본 연구에서는 분당-용인서북부 지역의 거주환경 비교분석을 통해 연속적인 중소규모 택지개발의 문제점을 파악하고 향후 신도시개발 및 주변지역 도시관리의 방향을 제시하고자 한다. During the 1990's, five new towns were constructed around Seoul such as Bun-Dang and Il-San. These new towns are very popular since they were created based on systemic urban planning and they provide various residential amenities. Many people consider them livable cities. Taking such advantages, other small-scale new public and private developments continued around those new towns and consequently created 'agglomerated region with new development'. The most representative area is Bun-Dang and north-western Yong-In area which are formed along the Seoul-Busan expressway. This area is a mega-community having more than one million residents in 2005.Judging from recent development trends in the Seoul metropolitan area, it is expected that the formation of other 'agglomerated region with new development' would be continued for the time being. This study is aimed to analyze the residential environment of Bun-Dang and north-western Yong-In and find implications to the management of 'agglomerated region with new development'. The relevant existing studies have their limits, only focusing on analyzing current conditions and pointing out current problems. This study could be differentiated from the existing analyses in that it conducted comprehensive analyses on various factors that constitute urban residential environment. The conclusion of this study was derived from diverse analyses of current development condition, residential sites, regional transportation, awareness of residents, and oversee cases.

본 연구는 경기 뉴타운 시민대학 프로그램으로 진행된 안양 만안뉴타운 도시설계안을 대상으로 프로그램 운영평가와 결과물 분석을 통해 향후 주민제안형 도시설계의 시사점을 도출하는 것을 목적으로 한다. 뉴타운 시민대학은 기존 강의 위주의 방식에서 벗어나 주민이 직접 참여하여 분석하고, 설계안을 작성 제안하는 스튜디오 방식으로 진행되었다. 본 연구의 대상인 안양 만안팀의 계획안 '자연, 문화, 역사, 사람이 공존하는 Eco-Cycle 만안'은 2010년 시민대학의 대상을 수상한 주민제안형 도시설계안이다. 만안팀은 지역분석과 대안설정을 통해 문화, 여가, 자연이 공존하는 공간으로 대상지역을 계획하였으며, 주민설계안이 실제 뉴타운의 재정비촉진지구 계획에 반영되었다. 본 연구를 통해 주민들이 직접 참여하고 디자인한 뉴타운 시민대학의 도시설계 작성과정과 프로그램을 살펴보고 공공디자인으로서 주민제안형 도시설계의 가능성과 방향성을 제시하고자 하였다. This is a study regarding the efforts of the Gyong-gi Newtown Citizen Academy in Anyang Man-an Newtown and their role in shaping the urban design of their living environment. Our goal is to gauge how citizen participation may factor into the design process, from the early stages to the end result. The Newtown Academy diverged from the existing methods of a lecture centered approach to one that encouraged direct participation from the local citizens. We analyze the process and manner in which they drew up the plans. Our research focused on the winning proposal from the 2010 Citizen Academy Design competition, entitled 'Coexistence with Nature, Culture, History, Human - Eco-Cycle Man-an'. The Man-an team conducted regional analyses to come up with their own alternatives that would allow culture, leisure and nature to coexist in the space of their targeted area. The Newtown redevelopment promotion district reflected the actual implementation of the Man-an team's design. This study examines an urban design process in which citizens become directly involved, which presents the possibilities and directions of an urban design that is public and resident-oriented, in nature.

It was attempted to develop an auto part by over molding injection mold that produces precision products in high productivity with use of an eco-friendly TPE substitute material for NBR. NBR is currently used in motor gear cover, one of the key parts in motor module for auto doors. Gear cover is composed of plastics and rubber mostly today, which requires a two (2) step process for production using two presses of different types. A hot press is used at this time for forming the rubber, which has drawback of requiring a rather long forming time of 400 seconds for one forming process. Even though this difficulty is overcome by reducing production time through employment of multi-cavity molds, time for forming process must be shortened for improvement of the productivity eventually, and the existing method of insert injection for products that have been formed with plastic material must be outgrown. In this point of view, over molding injection using TPE has a big advantage. Forming time is shortened to 54 seconds, and working the two (2) processes in series by one (1) press could solve the durability problem caused by deflection of the plastics, not to mention shortening the process time. Enhancement of productivity by almost 80% and improvement in the accuracy of the product could thus be achieved.
나노 임프린트 공정을 이용한 결정형 실리콘 태양전지 효율 향상 기술

In order to increase cell efficiency in crystalline silicon solar cell, reduction of light reflection is one of the essential problem. Until now silicon wafer was textured by wet etching process which has random patterns along crystal orientation. In this study, high aspect ratio patterns are manufactured by nano imprint process and reflectance could be minimized under 1%. After that, screen printed solar cell was fabricated on the textured wafer and I-V characteristics was measured by solar simulator. Consequently cell efficiency of solar cell fabricated using the wafer textured by nano imprint process increased 1.15% than reference solar cell textured by wet etching. Internal quantum efficiency was increased in the range of IR wave length but decreased in the UV wavelength. In spite of improved result, optimization between nano imprinted pattern and solar cell process should be followed.
