최근 디스플레이 기술은 급속도로 발전해 가고 있다. 정보화 기술의 발전으로 언제 어디서나 쉽게 정보를 얻을 수 있는 유비쿼터스 시대로 접근하고 있으며, 휴대가 간편하고 이동성을 가진 휴대용 기기가 인기를 끌고 있다. 이에 따라 더 얇고 더 가벼우며 휴대하기 쉬운 디스플레이가 요구 되고 있고, 더 나아가 떨어뜨려도 깨지지 않고 유연하며, 디자인 변형이 자유로우며, 때론 종이처럼 접거나 휘어지거나 두루마리처럼 말을 수 있는 이른바 "플렉서블 디스플레이"에 대한 필요성이 점점 대두되고 있다. 이러한 첨단 디스플레이의 핵심 소자 중 하나는 산화물 박막 트랜지스터 이다. 산화물 반도체는 넓은 밴드갭을 가지고 가시광선 영역에서 투명하며, 높은 이동도를 가지고 있어 차세대 평판디스플레이, 투명디스플레이 및 플렉서블 디스플레이용 박막트랜지스터(TFT)를 위한 채널층으로써 광범위하게 연구되고 있다. 하지만 현재 대부분의 산화물 박막 트랜지스터 제조 공정은 고온에서의 열처리를 필요로 한다. 고온에서의 열처리 공정은 산화물 박막의 제조 공정 단가를 증가시키는 문제점이 있으며, 산화물 박막이 형성되는 기판의 녹는점이 낮은 경우에는 상기 기판의 변형을 가져오므로(예를 들면, 플라스틱 기판, 섬유 기재 등), 상기 산화물 박막이 적용되는 기판의 종류에 제한이 생기는 문제점이 있었다. 이에 플렉시블 디스플레이 등을 위해서는 저온공정이 필수로 선행 되어야 한다. 산화물 TFT는 당초, ZnO계의 재료가 연구되었지만 2004년 말에 Hosono 그룹이 Nature지에 "IGZO (In, Ga, Zn, O)"을 사용한 TFT를 보고한 이후 IGZO, IZO, ISZO, IYZO, HIZO와 같은 투명 산화물반도체가 TFT의 채널물질로써 많이 거론되고 있다. 그 중에서 인듐갈륨 산화물(IGO)는 삼성분계 n-형 산화물 반도체이고, 채널 이동성이 좋고 광투과도가 우수해 투명 TFT에 매우 유용하게 사용할 수 있다. 이 실험에서 우리는 인듐갈륨 산화물 박막 및 트랜지스터 특성 연구를 진행하였다. 인듐갈륨 산화물 박막은 상온에서 rf-magnetron sputtering법을 사용하여 산소분압 1~10%에서 증착 되었다. 증착된 인듐갈륨 산화물 박막은 cubic $In_2O_3$ 다결정으로 나타났으며, 2차상은 관찰 되지 않았다. 산소분압이 10%에서 1%로 변함에 따라 박막의 전도도는 $2.65{\times}10^{-6}S/cm$에서 5.38S/cm 범위에서 조절되었으며, 이를 바탕으로 인듐갈륨 박막을 active층으로 사용하는 bottom gate 구조의 박막트랜지스터를 제작 하였다. 인듐갈륨산화물 박막트랜지스터는 산소분압 10%에서 on/off 비 ${\sim}10^8$, field-effect mobility $24cm^2/V{\cdot}S$를 나타내며 상온에서 플렉서블용 고 이동도 소자 제작의 가능성을 보여준다.

2010년 기준 세계 물산업은 약 4,800억불 규모이며, 2025년에는 약 1조 달러 규모로 성장할 것으로 전망된다. 또한 기후변화 등의 요인으로 물산업의 범위는 물순환체계 전과정을 포괄하는 "유역종합개발+상하수도+대체수자원"으로 확장될 것으로 예측된다. 그러나 지금까지의 국내 물산업 육성은 주로 상하수도 분야 중심으로 국한되어, 기후변화에 대응한 유역종합개발 분야에 대한 시장 진출기회를 상실하고 있다. 상하수도 중심의 물산업은 이미 선진 메이저 기업들이 선점하여 치열한 경쟁이 벌어지고 있는 '레드오션'이라 할 수 있으므로, 새로운 물산업의 강국으로 부상하기 위해서는 우리가 가진 장점을 바탕으로 물산업의 새로운 영역을 개척하는 방안에 대한 연구가 필요한 시점이다. 본 연구는 먼저 국내외 물순환체계 전과정(유역종합개발+상하수도+대체수자원)에 대한 시장 조사을 통해 세계 물산업 시장을 프로젝트 유형별, 지역별로 분석하고, 이를 토대로 국내 물산업 육성과 해외진출을 위한 당면 과제를 다음과 같이 제시하였다. 첫째, 민관협력을 위한 제도적 틀을 형성할 필요가 있다. 정부의 역할이 매우 중요한데, 정부 또는 기금이 자금의 단순한 대부자에서 적극적인 투자자로 전환함으로서 국내 민간기업들의 해외시장 진입장벽을 낮추어 줄 필요가 있다. 정부 주도의 민관협력이 활성화되면 참여 기업의 재무적 리스크를 현저히 줄일 수 있다. 또한, 상하수도 운영 경험을 축적한 공기업이 해외진출 지원기능을 수행하도록 하여야 한다. 즉, 공기업이 민간 기업의 경쟁자가 아니라 지원자가 될 수 있도록 프레임을 바꿔주어야 한다. 둘째, 물산업 클러스터의 형성이다. 물산업 제조업은 대부분 중소 벤처기업으로 독자적인 해외진출이 곤란하므로, 물전문 공기업이 중소 벤처기업 육성 및 해외진출의 앵커 역할을 담당하는 것이 필요하다. 이스라엘이나 싱가포르의 물산업 클러스터처럼 Anchor 역할을 행하는 공기업과 민간기업이 장기적 협력관계를 구축할 수 있는 기반을 마련해야한다. 셋째, 신시장 역량의 창출이다. 기후변화로 크게 성장할 전망인 통합물관리 시장에 대한 전략적 접근이 요구된다. 우선 ODA 등 대외 원조자금을 활용하여 투자비가 적게 들고 정보를 선점할 수 있는 조사 설계부터 시작하여, 댐 및 수력개발, 상하수도 건설 운영 등에 단계적으로 접근할 수 있을 것이다. 또한, 향후 도입될 예정인 물인프라의 Smart 기술, 첨단 수처리 기술 등을 활용하여 새로운 시장을 개척해야 한다. 4대강살리기 사업, 해수담수화 등 조기에 경쟁우위를 갖출 수 있는 사업과 기술을 Flagship Project로 브랜드화하여 우리나라를 "물강국"으로 포지셔닝할 경우 세계 물시장 공략에 보다 효과적일 것으로 판단된다.

High-barrier films are used to store cultural heritage objects in a safe environment sealed from oxygen and moisture. One of the high-barrier films use populary E manufactured by Japanese company M from the 1990's. However, this product has stayed in wide use, due to dearth of research on related subjects - including studies comparing it with other similar products-, in spite of the fact that high price information about its characteristics and environmental conditions is largely lacking. This study examines the characteristics of a number of high-barrier films with the goal to establish environmental standards for safer conservation of cultural heritage objects. E by the Japanese manufacturer M is compared with four other films; an electronics packaging films by a Korean firm, a film specially produced for the purposes of experiment in this study and a zipper bag-type film. Experiments were performed to compare the properties and gas blocking ability of the films by looking at their cross-section and measuring the thickness, tensile strength, elongation, absorbance of UV and visible light, yellowing and the permeability for oxygen and vapor. Based on these experiments, there are observed changes under different environmental conditions and depending on the length of use through temparature and humidification reproucing test. The results showed that while the high-barrier film by the Korean manufacturer was suitable for use as a packaging material for cultural heritage objects, the zipper bag-type film (P) was ill-adapted for this purpose. Based on the experiments reproducing the real-world environment, the length of useful life was also determined for each.

The automobile industry has developed Advanced Driver Assistance Systems (ADASs) to prevent traffic accidents and reduce the burden for drivers. One example is the Lane Keeping Assistance System (LKAS), which was developed for automotive vehicle systems for safety and better driving. The main system of the LKAS supports the driver while maintaining the vehicle within a lane. LKAS uses a radar sensor and camera sensor to collect information about the vehicle's position in the lane and send commands to the actuator to influence the lateral movement of the vehicle if necessary. Recently, vehicles equipped with LKAS have become commercially available. Test procedures for international LKAS evaluation are being discussed and developed by international committees, such as the International Organization for Standardization and United Nations Economic Commission for Europe. In Korea, an evaluation of LKASs for car safety is being planned by the Korean New Car Assessment Program. Therefore, test procedures should be developed for LKASs that are suitable for the domestic road environment while accommodating international standards. We developed a test scenario for LKASs and propose a formula for obtaining the target relative distance. To validate the methods, a series of experiments were conducted using commercially available vehicles equipped with LKAS.

A train overturn accident occurred on March 1993 in the Gupo area, northern part of Pusan, unfortunately had taken a heavy toll of lives and caused a great loss of property as well. The reasons for the subsidence of the basement under the railroads, which presumed to be the main cause of the accident, have been investigated from many different angles, including conventional geotechnical investigation methods. The deduced nuin reasons of the subsidence were: 1. blasting for tunnel excavation (NATM) at about 39 meter under the railroads, and 2. unexpected change of bedrock conditions along the direction of tunnel. But this accident was derived nrranlv from the lack of geological and geotechnical information under railroad area because it was impossible to drill beneath the railroads. This paper introduces a new geophysical survey techniqueseisrnic geotomography, and shows some results of the method applying to investigate the underground structure of the accident area. This method not only overcomes the unfavourable environment which many conventional investigation methods cannot face, but produces an image of underground structure with high resolution. Furthermore, the outputs from geotomogaphic analysis could provide very valuable in-situ basic parameters (like seismic velocities, elastic moduli, etc.) which is essential to the design and construction.

Informal engineering education program for high school students was developed to cultivate engineering literacy using the human resources and facilities of university. Plant factory, a smart farming technology, was selected as a main theme, and the novel engineering camp program involving engineering design activities and intra-linter-team works was planned. The camp program was applied to 38 high school students in an active learning classroom. Five teams were constructed according to elemental technologies such as biotechnology, information-communication technology, energy engineering, mechanical engineering and architectural engineering, and the students were participated in intra- and inter-team activities to achieve the final goal of 'the construction of a plant factory in school'. The team works were conducted according to the eight steps of engineering design process (identifying the problem and need, identifying criteria and constraints, brainstorming possible solutions, selecting the best possible solution, constructing a prototype, testing and evaluating the solution, communicating the solution, and refining design). Participants' satisfaction survey showed that the satisfaction on the contents of engineering design was 4.48 on 5-point Likert scale. The participants' satisfaction on creative activity and systematic methodology was 4.43 on 5-point Likert scale. 97% of participants responded positively to team works, and 92% of participants were satisfied with career mentoring activity supplied by undergraduate/graduate students. These results indicates that the engineering camp program involving engineering design activity and intra-/inter-team works can contribute to cultivate engineering literacy such as creativity, problem solving ability, collaboration, communication skills for high school students, and to increase their interests in engineering fields.

CIP, or Corporate Identity Program is a program to standardize, conforming to a set of regulations, various visual media which form a corporate environment based on the concepts drawn from the corporate strategies in order to actively create a planned but ideal corporate image. However, both the recent corporate renovation and the emergence of a new type of corporations prompted by a rapid change in an corporate environment caused the existing corporate concepts to be adapted to such a change. Particularly various visual media related to a corporate image are getting digitalized, and the emergence of a new and varied type of visual media give rise to a new pattern of the identity design accommodating such changes. It may be improper and insufficient for the existing CIP to be applied on the franchising business which is considered most suitable for the new corporate environment. Business firm's office work has long been operated in an computing environment where the computer does all the work, and an individual home as well as small business began widely using the computer. It may therefore be necessary that the corporate identity design for the franchising business should include not only the use of visual media but new, ultramodern information media as well, departing from the CIP heavily centered on the usual print media. This study, for this reason, separates the identity design for the franchising business from the existing CIP to call it FIP, or Franchise Identity Program, and discusses its concept and details.

In spite of adverse circumstances, dairy food industry of Korea has been developed continuously with the every efforts of farmers, processors, researchers and government officers. Development and extension of new technology, such as safety assurance, improvement of nutritive ingredient, and keeping freshness are very important issues considering short shelf life of dairy products which are prevalent in Korea. In addition to, demands for advanced technology would be increased rapidly with the increase of consumption development of high quality products supply structure, decrease of production basis, and appearance of environmental problems. And demands for information about standard would be enlarged. Development of new products and technology for quality improvement should be evolved with the application of developed technology and cooperation of relative institutes in order to enlarge the consumption of milk and dairy products. In conclusion, efficient production on the basis of balance and development of dairy products which are safe and high quality are the most important subjects for the development of dairy industry in Korea.

This study is to consider economic, political, socio-cultural and environmental characteristics of the new urbanization process and its spatial structures and urban policy of Seoul in the 1990s. Some experimental findings which have been identified throughout this study can be summarized as follows. First of all, Seoul, the largest city in S.Korea has experienced a restructuring process of economy, which has been promoted by the development of producer services as well as knowledge- based or high tech industries. Secondly, the autonomy of Seoul has increased after the introduction of local self-government, with relatively higher self-management of local finance than other cities, strengthening the tendency of enterpreneurialism, empowering civil movements, and increasing the political participation of women. Thirdly, in the socio-cultural aspect, the material wants to gain a certain identity through consumption, using urban environments culturally, varying consuming attitudes and ways of leisure times in relation with the rapid development of transportation and information communication. Fourthly, in the environmental aspect, Seoul has tried to introduce the concept of sustainable development in terms of increasing wants on the quality of life, and to develop a pro-environmental eco-city with environmental rehabilitation, constructing green space and eco-park. Finally, in the spatial dimension, Seoul has shown a structuration of multi-centers, with highly spectacular urban landscapes and seemingly authentic urban planning. These results make us confirm that Seoul has been in the process of new urbanization which can be distinguished from the previous one.
