The purpose of this study is to suggest some interior design directions for university library in the circumstances of rapid change of user's demand for the library. In order to extract some ideas about designing the library, I analyzed the libraries of UC Berkeley which has tried to transform the existing condition of the building for satisfying user's new needs. Informations of compositions, layouts of furnitures and book shelves, environmental conditions of 25 branch libraries of UC Berkeley, and spatial behavior patterns in libraries were surveyed and analyzed to get insights to design a new model of library buildings. The interesting phenomena got from the survey is that most of the library users used their own laptop computer in the library regardless of environmental conditions of the library or book types. In conclusion, as the library is changing to the place of studying, not of reading books, four design directions for the library are suggested in this research as like these; 1) Establishing a Regulation Free Environment for a user, 2) Enhancing the Aura of Books as an Interior Design Element, 3) Supplying Personalized Spatial Characters, and 4) Providing an Impactful Space.

This study investigates the mutual effects of the physical environment and the characteristics of user's need in the children's libraries of open plan type. The children's library as a flexible space should accept user's diverse needs. Especially, Children express more positive and diverse behaviors than adults in physical environment. As the design information obtained from observation of children's behaviors are put to architectural design, the more affluent environment in which children can do positive behaviors can be made. We used two research methods of the behavior observation and interview for the children's library, and could formulate various using actions through the behavior setting observation for using library. A relational description for reading environment in this study, based on the affordance and the behavior setting theories, provided us with rich accounts for the psychological and sociocultural resources in the children's library. Consequently, the following results can be summarized. First, children need territories for family use and for place and are using library effectively through taking the two territories. Second, the zoning according to age category should be done, as behavior patterns were observed differently according to age. Third, the space composition with openness should be designed, as children need social relation and learning through imitation and observation.

A digital hologram generated by a computer calculation (computer-generated hologram or capture using charge-coupled device [CCD] camera) is one of the most expensive types of content, and its usage is expanding. Thus, it is highly necessary to protect the ownership of digital holograms. This paper presents an efficient visual security scheme for holographic image reconstruction with a low scrambling cost. Most recent studies on optical security concentrate their focus on security authentication using optical characteristics. However, in this paper, we propose an efficient scrambling method to protect a digital hologram. Therefore, we introduce in this paper several scrambling attempts in both the spatial domain and frequency domain on the basis of the results of analyzing the properties of the coefficients in each domain. To effectively hide the image information, 1/4, 1/256, and 1/16,384 of the original digital hologram needs to be scrambled for the spatial-domain scheme, Fresnel-domain scheme, and discrete cosine transform-domain scheme, respectively. The encryption schemes and the analyses in this paper can be expected to be useful in the research on encryption and other works on digital holograms.

The needs of 3-D data have been increasing for various applications like visualization, 3-D modeling, planning and management as well as entertainment. Mobile mapping has become a quick and practical means for acquiring necessary 3-D data for above-mentioned applications. A mobile mapping system mainly consists of two main components, viz. data acquisition devices and positioning devices. The data acquisition devices consist of CCD cameras or/and laser scanners. The positioning devices consist of GPS, INS, Odometer (shaft encoder) and some other referencing devices. The overall accuracy of mobile mapping system depends on the accuracy of positioning devices and their integrated output. Though, GPS is the main input device for the position information, the signal is not available for the computation of position all the times in urban area. The GPS satellites are normally obstructed by high-rise buildings. Thus it is very important to understand the accuracy of such a system in different environments and means to solve such problems. We have developed a mobile mapping system called VLMS (Vehicle-borne Laser Mapping System), which consists of CCD Cameras, Laser scanners, GPS, INS and Odometer. In this paper, we will present and discuss the accuracy of this system with data acquired in different environments (open area, urban area, tunnel, express way etc) by analyzing the data with respect to other existing digital data.

Massive migration is underway in rapidly urbanizing Guangzhou, the south gate of P. R. China. Over half the migrants choose to rent in "villages-in-the-city" in the downtown area because of the low-cost and prime location. The overpopulation and resulting poor environment and high crime-rate turn villages-in-the-city into de facto ghettos. As a result, these ghettos are undergoing a manner of demolition-development, leaving migrants' housing needs unmet. A private-sector initiative-the Tulou Commune-intends to address this considerable market potential. Targeting low-income groups, the Tulou Commune creates a socio-spatially exclusionary enclave. This paper analyzes the Tulou Commune and the implications if more low-income migrants shifting from village-in-the-city (excluded ghetto) to Tulou Commune (exclusionary enclave). This study argues that the intervention of the private sector causes the demographic, social, and spatial similarities and differences of the two living arrangements. Socioeconomic and institutional factors also affect the initiative. This study also provides more empirical evidence in the field of low-cost housing and socio-spatial development in transitional Chinese cities. As the first project of its kind, the analysis of the case can suggest how to improve strategies for accommodating migrants in the future.

The senior welfare centers should provide integrated welfare services to the elderly whose needs are in change. So this paper tried to find a direction for improvement by identifying the spatial organization of the centers which are in Yeosu, Suncheon and Gwangyang. Classification of spaces of senior welfare center followed the guidelines 2020 for senior welfare center from Ministry of Health and Welfare which are consultation, medical rehabilitation, day or short-term protection, social education, home welfare, employment, welfare and public relations and PR planning and by adding management and public space. The above factors are invested and analyzed. The results of the survey and analysis of seven senior welfare centers are as follows. First, in the survey, the spatial organization of the senior welfare centers surveyed showed that the larger the size is, the dominantly lager the social education space is. Second, the space for day or short-term care, and employment is less than 1% of the total area, and most senior welfare centers do not have a basic space for this. Third, the space related to home welfare and counseling is very small, and more than half of the senior welfare centers do not have space related to it.

현대사회에서 대표적인 제3의 공간인 카페는 학업과 휴게 등에 중요한 공간으로 사용되고 있다. 카페를 방문 규모에 따른 공간적인 요구사항을 이해할 필요가 있는데, 좁은 카페의 경우, 더 넓고 높고 깊게 보일 수 있는 디자인 방법을 파악하는 것은 이용자나 디자이너들에게 도움이 될 수 있다. 본 연구는 공간의 깊이감과 머물고 싶은 의사의 관계를 시선추적기와 공간 이미지를 이용하여 연구한 것이다. 56명의 실내디자인 학생들은 15개의 렌더링으로 개발된 이미지를 함께 비교하여 보며, 어떤 공간이 가장 깊어 보이는지에 대해 응답하였다. 또한 주어진 공간을 카페로 가정하여 1인 방문 시, 그리고 단체로 방문 시 각각 어느 공간에 머물고 싶은지 응답하였다. 공간을 탐색하는 과정의 시선은 시선추적기를 통해 측정되었다. 연구의 결과, 동일한 규모의 공간일지라도 실내 및 가구요소에 따라 깊이감이 다르게 느껴짐을 보여준다. 어두운 벽에 작은 장식과 분리된 가구가 있는 공간이 밝은 톤의 벽에 큰 장식이 있거나 아예 장식이 없는 경우, 그리고 하나로 연결된 가구가 있는 공간보다 더 깊어 보인다고 인식되었다. 공간의 깊이감은 1인 방문자에게 중요한 요소이나, 여럿이 방문한 경우에는 큰 고려 요소는 아니었다. 연구의 결과는 공간의 깊이감이 카페 방문객의 규모와 관련해 머물고 싶은 의도에 어떤 역할을 하는지 밝히는데 도움이 되리라 본다.

강우는 수문 순환에서 중요한 요소 중에 하나로 시 공간적 변동성이 크므로 정확한 공간 강우장의 파악이 요구된다. 열대강우 관측 위성(Tropical Rainfall Monitoring Mission, TRMM)에서 제공하는 3B43 월 누적 강우량 자료는 25 km의 공간 해상도를 갖고 있어 공간 강우장의 정확성을 높이기 위해 상세화 기법을 적용하여 1 km의 공간 해상도로 생성하였다. Terra 위성에 탑재된 MODIS (Moderate Resolution Imaging Spectroradiometers) 센서가 제공하는 정규식생지수(Normalized Difference Vegetation Index, NDVI) (공간 해상도 1 km)와 강우 자료의 관계성을 회귀식으로 나타냈고 상세화 기법에 적용하였다. 이에 따른 결과를 지점과 위성 강우 자료와의 차이를 통해 보정하는 방법인 GDA (Geographical Difference Analysis)와 지점과 위성 강우 자료와의 비율로 편차를 보정하는 GRA (Geographical Ratio Analysis) 상세화 기법을 사용하여 공간 강우장을 나타내었다. 우리나라의 공간 강우장 결과를 지점 자료를 기준으로 비교 검증을 실시하였다. 그 결과 GDA 상세화 기법의 경우가 2009년(Bias=4.26 mm, RMSE=172.16 mm, MAE=141.95 mm, IOA=0.64), 2011년(Bias=17.21 mm, RMSE=253.43 mm, MAE=310.56 mm, IOA=0.62)으로 가장 잘 맞는 것으로 나타났다. 이를 바탕으로 우리나라의 공간 강우장을 1 km의 공간 해상도로 파악할 수 있었으며, 더 나아가 지점의 수를 늘려 보정을 정밀하게 하거나, 강우 레이더 자료를 가지고 상세화 기법을 적용한다면 더욱 정확한 공간 강우장을 파악할 수 있을 것이다.

우리가 살아가는 삶속에 깊숙이 파고든 공간정보는 유비쿼터스 시대에 맞춰 지능형 공간정보로 진화하고 있다. 또한 이를 이용한 다양한 서비스 모델이 소개되고 있다. 하지만 이러한 서비스에 대하여 사용자와 제공자에게 동시에 설명할 수 있는 분류체계는 존재하지 않는다. 이에 다양한 지능형 공간정보 서비스들을 체계적으로 분류할 수 있는 체계가 필요한 실정이다. 본 연구에서는 지능형 공간정보의 개념을 소개하고 공간정보 서비스들의 특성을 고려한 서비스 분류 체계를 개발하였다. 개발된 지능형 공간정보 서비스분류 매트릭스는 지능수준 척도, 공간정보 정확도, 서비스 영역을 기준으로 하였다. 본 연구에서 제안한 서비스 분류 매트릭스는 두 가지 관점에서 활용될 수 있다. 첫째, 지능형 공간정보의 수요가 늘어나면서 유사한 기능만을 가진 채 실수요를 반영하지 못하고 중복된 서비스들이 나타나는 현실을 개선시킬 수 있다. 둘째, 공간정보 산업의 현황을 들여다보고 새로 진입하게 되는 서비스의 목표 선정이나 미래의 발전 방향을 제시할 수 있다. 이러한 활용을 토대로 서비스 분류 매트릭스는 새로운 블루오션 창출과 같이 공간정보 사업 활성화를 이루는데 도움이 될 수 있다. 하지만, 서비스 분류 매트릭스는 향후 개발될 다양한 서비스를 적용하는데 있어 문제점이 없도록 수정과 보완이 필요하다. 그리고 분류 매트릭스는 궁극적으로 서비스 로드맵을 작성하기 위한 자료로 활용되거나 참조모델로서 활용될 수 있도록 해야 할 것이다. 하여 U-City의 미래를 더욱 밝게 할 것이다.
