The purpose of this study was to investigate the residents' use and occupancy-behavior in the activity areas of the senior nursing facilities, and to provide basic information to establish the appropriate physical elements for planning the activity areas. For the study, the observations in five facilities were conducted for one day, from 10 a.m. to 4 p.m by four researchers. The results of the study are summarized as follows: First, most of the using behaviors in the activity areas were the doing nothing or sleeping. The meals and program services were provided in only one activity area of the floor and it showed that the unit care system was perfunctorily conducted at those facilities. In the representative activity area, its openness was the main physical element influencing the spatial using frequency, while the accessibility and the openness in the sub-activity area were most important. The seating arrangements having comers were helpful for residents' interactions. Second, while facility programs and meals were provided in the specific activity area, there was no residents' occupancy in other activity areas at the same time. There were interactions including residents' conversations and watching/observations in non-designated activity areas such as the nursing stations and near corridors. But the residents' interactions and self-regulations were blocked by absence of territoriality, monotonous spatial compositions and furniture arrangements, insecurity of residents' privacy, wide or narrow areas, and isolated spatial type. Based on the results at the above, basic guidelines for planning the activity areas of senior nursing facilities can be proposed as follows: First, the isolated type and the sight interception should be avoided in representative activity areas. It should be partitioned with couple of areas through the appropriate furniture arrangements, and be prepared semi-private spaces in non-designated areas such as nursing station for the interactions among the residents and the staff. Second, in activity areas for small group, the isolated type is not also good for the residents' accessibility. The residents' privacy should be confirmed through the various spatial compositions, and enough areas need to be sure for the diverse furniture arrangements.

The primary purpose of this study is, using Landsat remote sensing data and a image processing software, ERDAS, to generate real data and image photographs on physical land use of the Seoul metropolitan region. The remote sensing data used in this study are Landsat MSS data (August 28, 1979) and TM data (May 31, 1991) which cover the Seoul metropolitan region of Korea. The spatial resolutions of MSS data and TM data are 57m X 79m and 30m X 30m respectively. In addition, this study aims at contrasting urbanization phases of the Seoul metropolitan region in 1979 with those in 1991, by making image photographs and statistics on physical land use. Summing up the major results, built-up area ratio within the Seoul city had been expanded from 41.9% in 1979 to 64.5% in 1991 and that within the radius of 40km of Seoul city hall had been expanded from 10.5% In 1979 to 19.8% in 1991. The data and technique developed in this study could serve as a useful tool in making various kinds of spatial plannings, that is, urban and regional planning, selection of optimal new town location, evaluation of public facilities location alternatives, etc..

The purpose of this study is to analyze the landslide susceptibility, containing the process, which reveals spatial relationships between landslides and geospatial data sets, which occurred in Janghung area in 1998. Landslide locations were detected from remotely sensed image and field survey and topography, soil, forest, and land use data sets were constructed as a spatial database in GIS. As the landslide occurrence factors, slope, aspect, curvature and type of topography, texture, material, drainage and effective thickness of soil, type, age, diameter and density of wood and land use were used. To extract the relationship between landslides and geospatial database, likelihood ratio was calculated and compared with the result of Yongin area. Also, the landslide susceptibility index was calculated by summation of the likelihood ratio and the landslide susceptibility map was generated using the index. As a result, it is expected that spatial relationships between landslides and geospatial database is helpful to explain the characteristics of lilndslide and the landslide susceptibility map is used to reduce associated hazards, and to plan land use and construction.

In recent, as rediscovery of the modern value is developed through the support by the government and the reinterpretation of the traditional culture, a Korean-style house(Hanok) also becomes an object of interest. Among these various viewpoints to see the Korean-style house, the necessity of a new spatial design approach to contain the types and functions of the architectural space of the Hanok appropriate to the modern society is raised which is not a passive approach to preserve the existing cultural assets. Out of the methods of the new spatial design of the Hanok which reflect the paradigm of the times, this study has the purpose to make an approach from the viewpoint of 'Restoration design'. As the 21 st century started, the recycle design whose active discussion and performance is made largely by Europe and Japan can be called a design method in the hardware part which enables continuous adaptive use of a building by applying a new use purpose and method to a building which doesn't use the recycle design or has low efficiency. In that meaning, it can be considered to be a very important architectural activity historically, archltecturally and spatially. Based on the methodological characteristics of the recycle design, this study largely divides the types of recycle into coherent recycle and imagery recycle and dedto s detailed methods of space, consinto ion and material and wardrobe used for each case to analyze the methods of concrete recycle design through the methodological analysis of recycle cases of the existing modern buildings. For the objects of recycle cases of the Hanok made recently based on the design methods acquired here, it was examined how the architectural and spatial characteristics of the Hanok can be reconsinto ed through what kinrecycmethods. The approach of the recycle design is considered to be a cornerstone to show a new architectural and spatial value in the viewpoint of the Hanok existence in modern times.

Revitalized alley-type urban commercial streets have recently received a lot of attention as a preferred place for people. The purpose of this study is to present implications in the planning and design methods for the making of alley-type urban commercial street. For that, theoretical review and case analysis were conducted on the street spatial characteristics of 'Jeonridan-gil' and 'Mangmidan-gil' in Busan, about site overview, street spatial composition, building use, streetscape and street furniture. The implications through the study are as follows. (1) Street environment should be created to improve the pedestrian space and environment. (2) The existing main use and the newly introduced use need to be coexisted. (3) The identity of the street must be maintained through adaptive reuse, etc. (4) The voluntary formation of the private sector and the planned making of the public need to be cooperated.

In this study, a GIS spatial analysis method adopted fuzzy concept was introduced and land suitability analysis of waste landfill were conducted through this method. Previous studies conducted site evaluation and land suitability analysis by appling spatial overlay of conventional GIS that based on the boolean logic of crisp set. However these method can not consider the uncertainty of spatial data and the incongruity of data classification criteria, because these method handle spatial data based on the boolean logic of crisp set. As not provided trustable analysis result, conventional GIS spatial overlay method lacks opportunity for expanding use in reality. This study selected waste landfill as facility for analysis and applied fuzzy spatial analysis method as an objective approach. In the concrete contents of study, a series process with regard to the definition procedure of membership function for continuous data and the fuzzy input value generation of spatial data for fuzzy analysis is established. As a result, in this study we proposed a method that derive parameters for deciding the membership function of spatial data by considering the criterion of data classification and factor selection for land suitability analysis of waste landfill.

This study is to evaluated the impact of varying spatial resolutions of DEM (2 m, 10 m, and 30 m), land use (QuickBird, 1/25,000 and Landsat), and soil data (1/25,000 and 1/50,000) on the uncertainty of Soil and Water Assessment Tool (SWAT) predicted streamflow, sediment, T-N, and T-P transport in a small agricultural watershed ($1.21\;km^2$). SWAT model was adopted and the model was calibrated for a $255.4\;km^2$ watershed using 30 m DEM, Landsat land use, and 1/25,000 soil data. The model was run with the combination of three DEM, land use, and soil map respectively. The SWAT model was calibrated for 2 years (1999-2000) using daily streamflow and monthly water quality (SS, T-N, T-P) records from 1999 to 2000, and verified for another 2 years (2001-2002). The average Nash and Sutcliffe model efficiency was 0.59 for streamflow and the root mean square error were 2.08, 4.30 and 0.70 tons/yr for sediment, T-N and T-P respectively. The hydrological results showed that output uncertainty was biggest by spatial resolution of land use. Streamflow increase the watershed average CN value of QucikBird land use was 0.4 and 1.8 higher than those of 1/25,000 and Landsat land use caused increase of streamflow.

Currently, many geographic information systems deal with only vector data. Therefore, handling raster data for various types of information is greatly needed. In this paper, we design and implement a raster processor which handles spatial information in a spatial object management system called Object Management system for Geospatial Application (OMEGA). We define the data structure of the raster information to be stored in the spatial object management system and implement it to a class library in order for use in making an application program. Furthermore, a query operation and related module is implemented to extract raster information. They are then imbedded in the query executer to process a query of the raster information. Simulation results are given.
