토지이용 분류 체계상에서의 종류라는 개념은 토지이용 변화의 분류 체계성에 그대로 적용시킬 수가 있다. 본 연구에서는 선형 판별 함수를 원용하는 최우법(Maximum likelihood method)으로 산출되는 토지이용분류의 공간적 결과와 Markov 전이 행렬 방법으로 산출되는 정량적 결과가 상호 보완하는 의미에서 합성모형으로 통합되었다. 본 연구에서는 다변수 판별 함수의 계산법과 Markov 연쇄행렬 계산법에 관하여 토의되고 그 합성 모형을 대상 지역에 실제 적용하여 그 결과 '90년, '95년 토지이용도가 예측 작성되었다. 모형화의 문제 및 예측의 정확도 역시 더욱 토의 되어야 하며 추후 개선의 여지를 남긴다.

This study aims to find out the characteristics and the type classification of contemporary public libraries in terms of browsing circuit. In so doing, it is to analyze 21 recently built libraries by using the browsing circuit, the spatial depth and the spatial layout. The study makes use of codes derived from the concept of 'Classification' and 'Frame' suggested by a pedagogist, Basil Bernstein. As a result, it shows that two codes are phased in overseas cases. In other words, one type is a lower depth of space and a high rate of rings with the multi-layer circuits and the three-dimensional circuit of multi-centered. the other type is the higher depth of space and a low rate of rings with the single-layer circuit and the multi-layer circuit of single-centered. In domestic cases, 4 types are shown. The characteristics of layout are seen as a radial shape and the rate of rings is lower than the overseas cases. It can be said that these results are a transitional phenomenon. For browsing circuit, domestic public libraries would be adapted to the three-dimensional circuit of multi-centered, a lower depth of space and a high rate of rings. By instructions of this plan, the real meaning of a public library will be come true.

본 연구의 목적은 공간데이터 구축공정에 표준으로 적용 가능한 관리방법론을 연구하는데 있다. 우리나라는 아직까지 구축공정 및 품질관리에 대한 체계적인 기준인 정립되지 않은 실정이어서 국가예산이 낭비될 우려의 소지가 있다. 또한 현재 공간데이터 구축과 관련된 법규는 기준이 명확하지 않은 경우가 있어서 공간데이터의 품질에 대한 신뢰성이 부족한 실정이다. 공간데이터의 제작 및 품질검사와 관련이 있는 법규, 국토지리정보원에서 수행한 공간데이터의 품질관련 연구 등 각종 문헌자료, 지방자치단체의 지리정보시스템을 구축한 경험이 있는 주요 업체의 공간데이터 제작공정 및 작업방법에 대하여 조사, 분석하였다. 분석한 내용을 기반으로 GPS에 의한 기준점 측량, 수준측량, 항공사진촬영, 수치지도 제작, 지형도 제작, 수치표고자료 제작, 항공사진 DB 구축, 정사영상지도 제작 등 8개 사업을 대상으로 선정하고 표준화된 관리방법론을 제시하였다.

Rural policies in Korea have been changed into amenity-oriented ones recently to enhance the quality of life for villigians, which should be supported by the amenity-oriented maintenance system for rural space or environment too. Although so many studies on the classification system of amenity resources had been carried out, few ones which classified them principally by their spatial characteristics had been tried. From the viewpoint mentioned above, this study tried to propose a tentative classification system of amenity resources focussed on their locational characteristics. By the literature review, its draft was prepared, and after 2-round expert checks, the final table determined, which composed of 3-subsystems; green, production and living environment. Through the field application works in two case villages, its practical applicability was ascertained, from which two regarding points were found; public usability of terms and seasonality of amenity resources, especially green ones.

In this study engineered steel fibres used as reinforcement for concrete were characterized by number of key mechanical and spatial parameters, which are easy to measure and quantify. Such commonly used parameters as length, diameter, fibre intrinsic efficiency ratio (FIER), hook geometry, tensile strength and ductility were considered. Effective classification of various fibres was demonstrated using simple multivariate computations involving principal component analysis (PCA). Contrary to univariate data mining approach, the proposed analysis can be efficiently adapted for fast, robust and direct classification of engineered steel fibres. The results have revealed that in case of particular spatial/geometrical conditions of steel fibres investigated the FIER parameter can be efficiently replaced by a simple aspect ratio. There is also a need of finding new parameters describing properties of steel fibre more precisely.

The drastic change of spatial structure in rural area and the recent rural development policies(related to settlement reorganization and plot rearrangement) make the rural space planning more important than ever. So this paper tries to evaluate the institutional aspects of rural spatial planning system focused on planning area. land use classification and hierachical order between existing plans. The results of this study can be summarized as follows. First, the rural planning areas are classified into 4-tiers(e.g., Gun, Myon, District, Village). Second, the rural land use planning has 3-tiers(e.g., macro, mediate and micro zoning) from the viewpoint of land use classification system, but it doesn't have mediate-micro zoning system. Third, the spatial plans in rural area, positioned in local planning, were categorized into regional planning system and land use planning system. However there's no linkage between both sides of each hierachial planning order.

The image labeling and classification is one of the important tasks for a content-based image retrieval and an image understanding. This paper propose a new technique to label and classify natural images with a color-spatial histogram and production rules. We show that our proposed method is very efficient for a natural image composed of a few regions.

Spatial resolution of land covers from remotely sensed images can be increased using super-resolution mapping techniques for soft-classified land cover proportions. A further development of super-resolution mapping technique is downscaling the original remotely sensed image using super-resolution mapping techniques with a forward model. In this paper, the model for increasing spatial resolution of remote sensing multispectral image is tested with real SPOT 5 imagery at 10m spatial resolution for an area in Bac Giang Province, Vietnam in order to evaluate the feasibility of application of this model to the real imagery. The soft-classified land cover proportions obtained using a fuzzy c-means classification are then used as input data for a Hopfield neural network (HNN) to predict the multispectral images at sub-pixel spatial resolution. The 10m SPOT multispectral image was improved to 5m, 3,3m and 2.5m and compared with SPOT Panchromatic image at 2.5m resolution for assessment.Visually, the resulted image is compared with a SPOT 5 panchromatic image acquired at the same time with the multispectral data. The predicted image is apparently sharper than the original coarse spatial resolution image.

산업의 공간적 입지에 대한 분포 패턴 분석은 관련된 공간정책 및 계획의 수립에 있어 매우 중요한 역할을 한다. 이러한 분석에 있어 먼저 고려되어야 하는 것은 어떠한 분석지표와 공간단위를 활용하는가에 있는데, 이는 지표와 공간단위에 따라 그 해석이 달라질 수 있기 때문이다. 이에 본 연구는 먼저 공간적 자기상관을 고려한 다양한 산업집적 지표들을 고찰하고 관련 지표에 따른 산업집적의 지역유형을 구분하며, 다음으로 개별입지, 그리드, 행정구역 등의 다양한 공간단위별 산업집적을 분석하는 방법론을 제시하여 뿌리산업에 대해 실증분석 하는 것을 목표로 한다. 실증분석 결과를 보면 공간단위에 있어서 그리드 단위가 행정구역 단위보다 세밀한 미시적 분석이 가능함을 알 수 있었고, 공간단위의 설정에 따라 발생할 수 있는 해석상의 차이와 같은 한계를 극복할 수 있는 것으로 기대된다. 지역유형 구분에 있어서는 울산광역시, 부산광역시, 창원시를 축으로 하는 동남권과 인천광역시, 화성시, 안산시를 축으로 하는 수도권 서부축이 뿌리산업의 산업집적 클러스터 지역유형으로 분석되었다.
