The facade in the street is a unfixed type, thus it is not easy to investigate the characteristic of structures. In addition, a color mainly depends on sensitivity, therefore, it is very difficult to provide the solution of the problems. The purpose of this study is to investigate the relationship between a form of the facade and a color, and to introduce the methodology and the direction of the color scheme for the facade in the street. for the purpose of this study, 47 facades are empirically analyzed. Based upon the results of research analysis, this study try to find out the relationship among the formative continuity of the facade in the street, a color, and the quality of the material. From the results, it suggests the new direction for the image formation of the facade in the street centering around a color. This study concludes that the characteristics of the facade in the street is discontinuous, and the color scheme is not based on the formative continuity. Moreover, the whole street is composed of each strong individual character. In order to harmonious creation of the facade in the street, primary colors and painting colors should be constrained. Finally, the color scheme based on the formative continuity of the facade in the street should be carefully considered.

This study is a proposal for the positive application of collage techniques into the process of interior design. For that, we need to set up the appropriate definitions of collage and to analyze its properties as a creative design methode of that field, in the basis of the twentieth-century art history. The study is divided into three sections as follows: 1) The traces of collage in the art movements such as Cubism, Dada, Surealism, and Pop art will be researched in terms of art concepts, appearances and, properties. 2) The relationships between collage and the main ideas of those art movements, as mentioned above, will be discussed for proving that collage is such an effective techniques as to erdxxly Post-modem ideas. 3) The examples of collage techniques and their effects appearing in Post-modem interior spaces will be surveyed for the purpose of proving its abilities as a creative design methode in interior design. Further studies should be succeeded for suggesting practical and educational models of its application.

본 연구는 기술개발 자체의 효과성을 개발된 기술의 시장성, 확대 보급가능성, 민간분야의 기술 로드맵과의 관계성을 도출하는 것으로 실제로 업계에서 다양한 인맥과 프로젝트의 경험을 가지고 있는 자에 의한 심층인터뷰를 근거로 한 정성적 판단과 시장조사를 통한 정량적 판단을 결합하여 멀티센서의 기술개발의 가치를 평가하는 후속 조치에 해당되는 연구이다. 직접적 측면의 산업적 파급효과는 2006년에는 시범적인 수준에서 적용된 사례를 중심으로 정리해 본 결과, 다음과 같이 요약될 수 있다. 첫째, 전문화된 기업의 경우 각자의 강점에 기반을 두어 멀티센서의 적용시장을 바라보고 있다는 점이다. 모든 소프트웨어의 생산을 서버 부분부터 웹 버전, 모바일 버전까지 모두 보유하고 있는 벡터 부분의 GIS 수준과는 달리 위성영상 및 멀티센서 분야의 소프트웨어는 대용량으로 인한 한계로, 서버중심, 웹 중심의 개발이 이루어지고 있으나 모바일 분야까지 확장되지는 않고, 차량항법장치와의 연계를 통한 확장을 꾀하는 수준이라고 요약할 수 있다. 둘째, 전문기업이 아닌 대기업의 시장분석 및 전략에 관한 부분을 요약하자면, 멀티센서와 직접적인 연관을 갖는 회사는 많지 않으나 대체로 U-city 사업 발굴 시 멀티센서가 융합기술이 요소기술로서 기여할 수 있을 것이라는 기대는 하고 있으며, 규모도 1,000억 원 대를 상회할 것으로 바라보고 있다. 셋째, 멀티센서 개발기술의 상용화 및 산업화를 위한 제거 요소 및 감소 요소, 증가 요소 및 새로이 만들어야 할 요소 등을 다차원 전략으로 제시하였으나, 전략을 구사할 기관이 산재되어 있어 제도적 차원의 뒷받침이 기술개발과 더불어 진행되어야 한다는 결론에 이르게 된다. 넷째, 개발된 4개의 기술에 대하여 KVA에서 산출한 기업평가 방식을 변형하여 적용하였는데, 위성영상과 DEM 개발기술이 87% 이상의 점수를 받아 가장 시장성 및 활용성이 높은 기술로 평가되었으며, 초다분광영상에 대한 기술은 70%를 겨우 넘는 수준에서 평가가 되었다. 멀티센서 공간영상정보 통합처리 기술 개발은 다목적 실용위성의 보유, 국가 NGIS 사업의 결과물이 상당히 축척이 되어 있고, 라이다(LiDAR) 기술의 도입을 위한 환경이 조성되었기에 다른 국가에 비해 멀티센서 기술의 적용과 산업화가 가시화 될 수 있을 것으로 기대된다. 그러나 멀티센서 자료의 수급이 용이하지 못하고, 법 제도적인 한계, 시장의 성숙도가 기대이하라는 점 등의 한계를 노정하고 있다.

There has been a recent spate in the usage of mobile device equipped GPS sensors, such as smart phones. This trend enables the posting of geo-tagged messages (i.e., multimedia messages with GPS locations) on social media such as Twitter and Facebook, and the volume of such spatial data is rapidly growing. However, the relationships between the location and content of messages are not always explicitly shown in such geo-tagged messages. Thus, the need arises to reorganize search results to find the relationship between keywords and the spatial distribution of messages. We find the smallest minimum bounding rectangle (MBR) that embedding k or more points in order to find the most dense rectangle of data, and it can be usefully used in the location search system. In this paper, we suggest efficient algorithms to discover a group of 2-Dimensional spatial data with a close distance, such as MBR. The efficiency of our proposed algorithms with synthetic and real data sets is confirmed experimentally.

New communication and information technologies such as the Internet are space-adjusting technologies. The Internet changes the spatial proximity by improving the connections between people and organizations separated by geographical distance This paper examines the digital position of individual nation-states on a global cyberspace. The number of inter-domain hyperlinks embedded in websites for 47 nations was gathered using the AltaVista in 2001 Data were also obtained on the geographical distance among the nations. The results indicate that the u.s. is the most central nation on the global cyberspace, followed by the U.K., Germany, Australia, Canada, Italy, France, China and Japan. The most peripheral nations are Uruguay, Luxemburg, and UAE. It also examines the relationship between the digital positions of 47 nations and their physical locations. The results indicate that digital structure on the cyberspace is not significantly related to geographical distance among those nations.

NAND type Flash memory has performing much researches for a hard disk substitution due to its low power consumption, cheap prices and a large storage. Especially, the NAND type flash memory is using general buffer systems of a cache memory for improving overall system performance, but this has shown a tendency to emphasize in terms of data. So, our research is to design a high performance instruction NAND type flash memory structure by using a buffer system. The proposed buffer system in a NAND flash memory consists of two parts, i.e., a fully associative temporal buffer for branch instruction and a fully associative spatial buffer for spatial locality. The spatial buffer with a large fetching size turns out to be effective serial instructions, and the temporal buffer with a small fetching size can achieve effective branch instructions. According to the simulation results, we can reduce average miss ratios by around 77% and the average memory access time can achieve a similar performance compared with the 2-way, victim and fully associative buffer with two or four sizes.

Geostatistical data or point-referenced data have the information on the monitoring stations of interest where the observations are measured. Practical geostatistical data are obtained from a wide variety of observational monitoring networks that are mainly operated by the Korean government. When we analyze geostatistical data and predict the expectations at unobservable locations, we can improve the reliability of the prediction by utilizing some relevant spatial data obtained from different observational monitoring networks and blend them with the measurements of our main interest. In this paper, we consider the hierarchical spatial linear model that enables us to link spatial variables from different resources but with similar patterns and guarantee the precision of the prediction. We compare the proposed model to a classical linear regression model and simple kriging in terms of some information criteria and one-leave-out cross-validation. Real application deals with Sulfur Dioxide($SO_2$) measurements from the urban air pollution monitoring network and wind speed data from the surface observation network.
