캠퍼스의 공간은 대학을 이루는 주요한 물적 자원 이며, 제한된 공간을 효율적으로 활용하기 위해서 공간사용현황을 파악하는 것은 중요하다. 다른 공간정보시스템은 공간데이터와 속성데이터의 불일치로 인한 문제점이 발생할 수 있는 여지가 있다. 이를 근본적으로 해결하기 위해서 본 연구에서는 공간 DBMS를 활용해서 캠퍼스 공간정보 시스템을 제안한다.

최근 들어서 환경유해물질이 인체에 미치는 영향에 대한 관심이 커지고 있다. 특히 환경 중에 존재하는 발암성 물질에 대한 연구가 활발히 진행되면서 이들 물질이 인체에 미치는 위해성이 밝혀지고 있다. 다환방향족탄화수소(Polycyclic Aromatic Hydrocarbons, PAHs) 는 환경에 존재하는 중요한 발암물질이자 돌연변이 유도체이다. PAHs는 화석연료의 불완전 연소 등에 의해 발생되고, 대표적인 오염원으로는 석탄 연소, 자동차, 가정 난방 등이 있다. (중략)

In this paper, the proposed watermark algorithm is based on energy distribution of the subband coefficients in the frequency domain and edge of the original image in the spacial domain. Out of these information, the KeyMap which decides the embedded position of watermark is produced. And then the binary watermark is embedded into the wavelet coefficient of LL3 subband using KeyMap and LFSR(Linear Feedback Shift Register).

This paper proposes a new short-term load forecasting method for special day, such as Public holidays, consecutive holidays, and days before and after holidays. when the load curves are quite different from those of normal weekdays. In this paper, two Artificial Neural Network(ANN) systems are applied to short-term load forecasting for spacial days in anomalous load conditions.

The Assessment using the observation is one of the common ways to know what the student knows and dose not. Using the obserbational Assessment, Teachers, analyzing student's growth, provide appropriate feed-back, and so they try to record every activities. but, accumulatively recording the result of observational assessment face time·spacial limits. and it is difficult to apply in a real classroom situation. Taking these into consideration, I'd like to take a look at the idea of check-list assessment that could record data observing student and contrive a practical ways of application.

The modified F-expansion method is used to construct analytical solutions of the foam drainage equation with time- and space-fractional derivatives. The conformable derivatives are considered as spacial and temporal ones. As a result, some analytical exact solutions including kink, bright-dark soliton, periodic and rational solutions are obtained.

This study aims to clarify the architectural characteristics of three houses of Choseon Exhibition. Exposition/exhibitions were thought to be a model for the world. It shows the real status of the development, and thinking with visions at that times; therefore, exhibited house models would be a good source for what to be considered for the ideal houses of that times. Through the study, we could find out as belows. 1. The houses exhibited conserved the sitting-on-floor living style, otherwise the most proposals for house improvement suggested a chair-and-table style because of its hygienic quality and integration of the life at home and at work(school, too). 2. The spacial scheme for-family prior over for-guest was emphasized, but models at the exhibition were structured with Japanese traditional spacial program, such as Jashiki(座敷), Kyakunoma(客の間) or Tsuginoma(次の間), which were all Tatami-floored. 3. Through this exhibition, it is clarified that the architectural society in colonial Korea also tried to improve the modern housings, not only direct reception of the developed proposals. These houses was planned with the acceptance of the locality, such like Ondol, a floor heating facility which the Japanese engineer improve the efficiency. 4. Also these exhibited houses became a start to recognize a house as a product, and spurred on commercialization. As the result, we could find out that these exhibited houses accepted the modern housing proposals selectively, and that even if the exhibitions shows the advance in usual these houses were planned with the very conservative notions.

This study analyses characteristics of space to facilitate community centering on cases of collective houses in Japan and uses the results as basic data to activate collective houses as an alternative form of housing in our country. To identify the characteristics of space for active communities with collective living space, this study conducted a theoretical examination on collective houses and housing, derived territoriality, accessibility, comfort and safety as factors of community activation and analysed various cases, and the results are presented as follows: First, territoriality is a necessary condition for formation of community, and a confined and physical space. It indicates the proper size of a space and diverse spacial areas which meet the needs of residents with the proper size and amount of space (space which can accommodate diverse generations including women, the aged and the young, flexible space which changes according to the purposes and program, space which supports leisure and hobby activities, and space which can accommodate outsiders). Second, accessibility indicates an environment which supports residents' easy use of space. As the more accessible it is, the higher the frequency of its use, spatial factors (piloti, backyards, benches and tables) should be provided, community space should be arranged in a central or decentralized way and community living space should be made for each floor. As for exits, accessibility should be considered in every way; entrances connected with community spaces, open entrances and entrances accessible from outside or individual living spaces. Third, comfort satisfies the physical and mental needs of residents through separation of floors and flows between the community and individual spaces for privacy and formation of eco-friendly spaces including vegetable gardens, gardens and plant arrangements. Fourth, safety should be considered for a higher quality environment with psychological stability and comfort, for which the following are recommended: installation of hand-rails, removal of thresholds, spacial design for the socially weak, duplex and open type structures for community space, open stages and halls, as well as indoor and outdoor openness through the use of windows.

The non-planned development of the rural area surrounding the Metropolitan area has become a social problem. The land development program until now has an aspect of not combining the spacial plan and the environmental plan. The land use and city development system based on development should change into a form that combines developing the area and conserving the environment. Therefore, this research attempts to compare the results of the overlay analysis and the gravity matrix which are ways to evaluate the value land that has a high environmental conservation value. The research area is the town of Seonggeo-eup, Cheonan City, and the reason for selecting this area is because it is expected to be densely populated as a connected area to the Metropolitan and the development pressure, such as expanding the industrial area, is high due to convenient transportation. The environmental factors used in the research are the relative altitude, incline, age-class, natural degree of the ecology, classification of the land covering and the NDVI, and the research methods used are the overlay analysis of the GIS and the statistical method. The overlay analysis results showed level 1 13.2%, level 2 30.7%, level 3 47.4%, level 4 1.0%, level 5 2.4%, level 6 5.4% and so on. The gravity matrix was classified as level 1 27.0%, level 2 9.3%, level 3 58.2%, level 4 2.4%, level 5 2.3%, level 6 0.9% and so on. These results are more appropriate than current methods for plans that value the environment because the analyzed results of the gravity matrix have a tendency to highly condense the environmentally valuable area. Consequently, if the spacial and environmental plans combine and therefore expand the efficient use of the land in the current state where the nation's concern in environment is getting higher, it is thought that it will contribute highly on the development of the nation's life quality.

공간정보 정책과 관련하여, 아직까지 그 개념이나 구성 및 체계에 관한 선행연구가 미미한 수준이며, 그 연구들마저도 정책이론 관점에서 공간정보 정책의 기본 구조체계를 제시하는 정도로, 공간정보 정책을 정립하기 위한 목적에서 기본 개념을 모색하려는 시도에 불과한 실정이다. 이에 본 논문에서는 2000년대 중반부터 시작된 기존의 PC기반에서 스마트폰 등 모바일 기반으로의 새로운 패러다임 변화라는 현재의 스마트사회에 있어, 한국의 미래국가경쟁력을 좌우할 공간정보기술 정책의 바람직한 미래전략 설정을 위한 전략방향을 고찰하고 대안을 모색해 보고자 한다. 이러한 연구를 통해 글로벌 차원에서 지리공간정보와 관련된 다양한 이슈와 기술 변화를 과학적으로 분석하고 국내지리공간정보에 대한 정책 및 연구 개발 로드맵 수립을 지원하는데 활용될 수 있을 것으로 판단된다.
