The shape of land surface work as a cradle for various environmental processes and human activities. As spatially distributed process modelings become increasing important in current research communities, a classification system that delineates land surface into characteristic geomorphological units is a pre-requisite for sustainable land use planning and management. Existing classification systems are either morphometric or generic, which have limitations to characterize continuous ecological processes over the landscape. A new classification system was developed to delineate the land surface into different geomorphological units from Digital Elevation Models(DEMs). This model assumes that there are pedo-geomorphological units in which distinct sets of hydrological, pedological, and consequent ecological processes occur. The classification system first divides the whole landsurface into eight soil-landscape units. Possible energy and material nows over the land surface were interpreted using a continuity equation of mass flow along the hillslope, and subsequently implemented in terrain analysis procedures. The developed models were tested at a 12$\textrm{km}^2$ area in Yangpyeong-gun, Kyeongi-do, Korea. The method proposed effectively delineates land surface into distinct pedo-geomorphological units, which identify the geomorphological characteristics over a large area at a low cost. The delineated landscape units mal provide a basic information for natural resource survey and environmental modeling practices.

본 연구는 한반도 전체의 2207 Mesh에 입력된 기온과 강수량의 6개요소를 데이터로 하여 인자분석하고 그 결과를 군화분석하여 한반도의 기후구분을 시도한 것이다. 결과로 나타난 기후구는 기발표된 여러 기후구와 유사성이 많아, 데이터로 택한 변수가 연평균 기온, 최난월 및 최한월 기온, 전년강수량, 여름 및 겨울 강수량 등 6개에 불과했음에도 불구하고 한반도의 기후의 특징이 잘 나타난 지리구라고 판단된다. 이것은 우리나라의 기후가 기온과 강수량, 특히 그 연평균치 및 계절적 집중도에 의하여 크게 지배되고 있음을 다시 한번 입증시켜 주는 것이라 생각된다. 그러나 뚜렷한 기후 특성을 지니고 있는 울릉도가 하나의 기후구로 나타나지 않는것은 적설량이나, 연간 강수일수 등 울릉도의 기후 특성을 나타낼 수 있는 변수가 입력되지 않았고, 울릉도의 기후현상이 나타날 정도로 기후구가 세분화되지 않은데 있는것으로 짐작된다. 본 연구에서 제시한 8개 기후구를 교과서용 기후구분의 12개 기후구와 비교해 보면, 북부내륙과 북부동안 기후구가 거의 같은 것을 비롯하여 여러면에서 공통성을 발견할 수 있다. 그러나 교과서용 구분의 내륙형과 해안형, 특해 서안형과 의 구분은 본 연구의 기후구와 비교할 때 지나치게 도식화한 느낌이 든다.

The present study examines the characteristics of the international literature of classification systems published in the period 1981-1990. The references in the 'Classification Literature' sections of International Classification and the references in these source items were examined. The present study focused on analyzing each of the following characteristics: format, subject, language, geographical origin, age, authorship and number of references. The findings from the data analyses show clearly that in the literature of classification systems, I) books were the most frequently cited format; 2) library and information science was the most frequently cited subject; 3) English was the major language; 4) the literature of each classification system was written predominently in English except for Library Bibliographic Classification; 5) the language of each source item was the same as that of the greatest number of references of that source item: 6) the U.S., Germany, India, Russia, and the U.K. were the major geographic origin of publication; 7) there was a very close relationship between country of publication and language: 8) the country of origin of the documents was cited more than any other country except for the U.S.: 9) Price's Index of the literature revealed that the literature was a soft science and the half-life of the literature was about 7.5 years; 10) there was a preponderance of single authorships; 11) the literature was not a scholarly or scientific literature, according to the average number of references in source items and the percentage of unreferenced items. The findings of this reference study provide a better understanding of the characteristics of the classification systems literature. They prove useful for the collection development and assist classification systems researchers to prepare linguistically for their careers and encourage international communication efforts.

Various statistical classification methods to predict election to the Major League Baseball hall of fame of are implemented and their accuracies are compared. Seventeen independent variables are selected from the data of candidates eligible for the hall of fame and well-known classification methods such as discriminant analysis and logistic regression as well as the recently proposed Mahalanobis-Taguchi system(MTS). The MTS showed a better performance than the others in classification accuracy because it is especially efficient in cases where multivariate data does not constitute directionally geographical groups according to attributes.

This research aims to introduce the theoretical basis of the studies of tourism resources, by review the research trends of tourism resources in the geography field. The geographical approaches to tourism resouces can be subdicided into 3 categories according to the subject. First, the classification of tourism resource types and the approach on the spatial distribution may be enumerated. This subject has been the object of the most interest and discussion to the geographers for tourism up to now. And from the viewpoint of contents, it has been developed by classifying the types of tourism resoures, which is based on the establishment of the range and standard of tourism resources and the spatial classification of types based on the distribution feature of the area. Second, the approach about cognition, preference and interpretation on the tourism resources as the background to induce tourism phenomenon and decide the tourism destination. Judging from the fact that most of this subject is starting from the behavioural study and that the right understanding and interpretation of tourism resource is the important factor to decide the preference degree of tourists, we have to have much interest about the field of tourism geoaraphy. Third, the development of tourism resources which is showing the active study recently and its influence and effect attendant upon it may be enumerated. Today, as the economic value of tourism is become important internationally, tourism resources are recognized as the important factor to induce the industrialization of tourism. And in the series of analytical studies related to it the interest has been transferred from the economic benefit analysis attendant upon tourism development including tourism resource and to the cultural, educational, environmental and psychological influence, etc. As the result of composite examination, for the geographical studies about tourism resources, the spatial scale and the contents are being subdivided and specialized. And in the side of subject and method of study, it is developing into the positive study based on the concrete data and the measuring and analytical frame.

This study aims to develop an ecoregion classification using a multi-hierarchy of environmental factors for spatial patterns in the capacities and potentials of ecological systems in mountain regions. To achieve the objectives, we describe the spatial distribution of environmental factors and identify the multi-hierarchy of these factors using spatial statistics. Lastly, we assess ecosystem-units using both a forest type map (yung & kung) and a forest soil map in order to present a ecoregion classification. This study was performed at a $1,168km^2$ area in Gangwon-do, Korea. Sedimentary rocks, particularly limestone (36.6%) exist in high proportions in the research area. While higher mountains are present in the north and central Korean peninsula, plain areas show large proportions along Odae and Pyeongchang river. In a multi-hierarchy, geology and elevation are identified as upper levels and landform classification (surface curvature, upslope area) is considered as a lower level. 'Geology+elevation+landform' shows equally higher ${\chi}^2$ values than that of other classifications and we map ecoregions based on this result. Uniqueness of environmental characteristics in the research area such as high proportions of sedimentary rocks and higher elevations influences our ecoregion classification. We are looking forward to considering this study as an effective approach to integrating various ecological themes for mountain ecosystem management.

For planning and developing rural regions, it is very important to understand and utilize regional characteristics including social, demographic, and economic aspects. The purpose of this study is to find effective analysis techniques and provide a procedure design for mining regional characteristics in South Korea through reviewing and analyzing 41 related studies. The engaged research methods can be classified into five categories (PCA+CA, PCA, CA, GIS, and PCA+GIS) with the combination of three methodologies: principal component analysis (PCA), cluster analysis (CA), and geographical information system (GIS). The combination of PCA and CA occupied about 40 % of research methods used in related studies. The analysis tool of Korean Rural Information Supporting System (KRISS) is designed based on the outcomes of this study and applied to classify the regional capacity of agriculture using agricultural census data (2000) for evaluating its applicability.

In this paper, we propose a coding method of remotely sensed satellite image data using region classification and interband correlation. This method classifies each pixel vector consider spectral characteristics. Then we perform the classified intraband VQ to remove spatial (intraband redundancy for a reference band image. To remove interband redundancy effectively, we perform the classified interband prediction for the band images that the high correlation spectrally and perform the classified interband VQ for the remaining band images. Experiments on LANDSAT TM image show that the coding efficiency of the proposed method is better than that of the conventional Gupta's method. Especially, this method removes redundancies effectively for satellite iamge including various geographical objects and for and images that have low interband correlation.

Land suitability classification(LSC) is an appraisal and grouping(or the process of appraisal anti grouping) of specific tracts(of land) in terms of their relative land suitability for a definEd use, and is one of the land use planning techniques. This paper reviews the selected studies on LSC whose purposes are to especially contribute land use planning in case of Japan, So, this study examines the LSC's application to Korea based on Japanes LSC studies with a view to development of the methods on LSC for rational land use planning in our rural area. The result resolves itself into Table 2. However, it is undesirable to borrow from Japanes LSC studies like that, because of the difference of administrative,geographical,traditional,social and economical conditions. Therefore, it is necessary that the many case studies and examinations should be carried out in order to develop the methods on LSC suitable to Korean actual circumstances.
