Industrial clusters and their boundaries are identified by factor and hot spot analyses for the greater Cincinnati metropolitan area in USA. While traditional input-output approach identified aspatial industrial clusters, this study combines traditional approach with GIS techniques to identify their boundaries. Combining the results of input-output industrial clusters with the leading industries groups, we have identified five leading industry clusters. They are food (20), chemicals (28), metal manufacturing (32), metal products (33), and machinery (35). We also used hot spot analysis to visualize each industry cluster on the research area by using Arcview software. Determining the degree to which such industries are associated spatially and their spatial delimitation may be an additional approach to measuring the efficiency of the spatial organization of an economy. It is hoped that the industrial clusters and industrial spatial clusters approaches may also proved the basis for the development of new models of the spatial arrangement of industry at a level more aggregated than that of the single plant or firm.

10년 후, 미래의 자동차는 더 이상 단순한 운송수단이 아닌 우리의 삶을 윤택하고 더욱 풍요롭게 만들어주는 일상의 공간(업무 휴식 정보)으로 진화 발전할 것이다. 이러한 자동차 패러다임 변화의 중심에는 지능형자동차 기술이 자리하고 있다. 지능형자동차 기술은 자동차산업뿐만 아니라 사회 경제 전반에 미치는 파급효과가 매우 크기 때문에 국가 경쟁력 강화를 위한 차원에서도 큰 가치를 지니고 있다. 또한 미래형자동차는 안전성 편의성 향상이라는 소비자들의 다양한 요구와 시장의 확대를 희망하는 기업의 요구가 잘 맞물려 있기 때문에 향후 기술개발에 대한 예산 확충 및 지원 확대가 절실히 필요하다. 지난 1990년대부터 지능형자동차 개발에 적극적으로 참여한 일본, 미국, 유럽 등 자동차선진국은 최근 각종 신기술을 개발해 시장에 내놓고 있다. 자동차 10대 강국 중하나인 한국은 21세기 세계 자동차시장 선점과 오는 2010년 세계 3위의 기술 강국으로 도약한다는 야심찬 계획을 세우고, 지난 2003년에 미래형자동차를 국가 '차세대 성장동력산업'으로 선정하였다. 이에 따라 국가연구개발사업인 '미래형자동차사업'을 출범시켰으며, 국내 자동차업계는 물론 대학 및 연구소 등과 연계하여 '지능형자동차' 등 3분야의 관련 핵심기술 개발에 박차를 가하고 있다. '지능형자동차 기술개발'이라는 비전과 목표를 달성하기 위해서는 IT기술과 자동차와의 융합기술 개발이 그 무엇보다 중요하다. 우리나라가 세계에 IT강국으로서 명성을 널리 자랑하고 있다는 점에서 지능형 자동차의 미래는 밝다고 할 수 있지만, 관련 분야의 인적자원 네트워크 구축이 보다 탄탄하게 다져지지 않는다면 이는 그저 '빛 좋은 개살구'에 지나지 않을 것이다. 끝으로 국내에서 진행되는 ITS 관련 프로젝트와 지능형자동차 개발 연구과제의 유기적 연계와 효율적 추진, 지능형 자동차 시험 평가방법 표준화, 국제 기술 표준화 및 안전규제에 적극 대응, 지능형자동차 신규제품 및 서비스의 도입을 위한 제도개선 및 정비 등에, 정부와 산 학 연이 지혜를 모아 중점 실행계획을 수립하고 행동으로 옮길 때 우리의 지능형 자동차 미래는 밝을 것이다.

The process of managing the results of national R&D projects, which are aimed at strengthening national competitiveness has been ineffective so far. The existing structure for managing the results of national R&D projects have largely been relying on just strong and managing the result of each project and not on the utilization and expansion of the results for further application. We aim at developing a system that would exceed the current system which heavily relies on a passive paradigm of management and circulation of technology. Through the newly developed system, we look forward to achieve the major goals of R&D, such as cutting down the expenses, increasing the margin improving the technology and expanding the influence of the research to other areas from through improving the system as well as the process for managing R&D projects.

The precast production has many advantages by fast construction period, labor-saving and high quality. In recent years, the application of the precast product has been increased in the earth retaining wall field. This paper presents the results of the numerical analysis that was carried out to evaluate the dynamic stability of precast and prestressed earth retaining wall under moving train load. The two-dimensional FEM analysis was used to the numerical analyses. The train load to act on trackbed is combined by the real measured roughness phase angle and quasi-static load. The dynamic stability is analysed by the displacement, acceleration and stress under moving train load at each specified location. The results of the analysis show that the precast and prestressed retaining wall has very stable capability for the railway.

The touch screen phone launched domestically in Korea, unlike the existing plane UI, it applied a cubic shape of 3D UI which provides three dimensional solid graphic. This study proposes to examine the correlation between the users' experience of 3D GUI, which were made by two different companies, and the brand. From this point of view, this study sets up a hypothesis about intimate correlation between individual differentiated brand and the user experience. Base on that, a model was designed. This study measured the satisfaction of user experience through the disclosure and non-disclosure of brand, focusing on 3D GUI cases which were launched so far, and it demonstrated that there was a clear difference in the degree of satisfaction. Through this examine, a brand was confirmed as one of the important element of user experience in using the 3D GUI that was launched competitively by companies. Therefore, the result of this study suggest that the designers need to establish strategies that make the brand as the core subject of design during the process of manufacturing product and service.
