This study examined emergency exit location with the most representing school floor type with a mathematical model that applied optimized algorithm in the field of engineering. Recent school buildings became much more diverse in floor planning than the old days. Nevertheless, architect's approach to building prevention against fire related emergency planning still relies on an personal experience and knowledge. Therefore, since school buildings are much more likely to be exposed to any fire related events, emergency exit planning has to be seriously evaluated with a scientific method. The algorithm, which acquires the number of persons in each spatial type(node) and the minimum physical distance between spatial types(arc), can propose the most optimized emergency exit locations. Consequently, this study compared an architect's fire exit planning with the scientific outcome of this study and suggested the most reliable emergency exit locations.

A spatial simulation model for rural and urban sprawl phenomena was developed with GIS and cellular automata techniques. The model finds out built-up areas invading toward rural areas required for development of existing urban area. Probability of land use change for optimizing the development area was determined using a land suitability analysis method interfaced with GIS methods, based on several criteria in terms of geographic and accessibility factors such as slope of land and distance from city center. Weighting values of the criteria were quantified by an analytic hierarchy process method. For model applicability test, the parameters of criteria were calibrated based on the changes in time series land use data of the test city for 1986, 1996, and 2000, which were classified by remote sensing techniques. Simulated and observed areas in land use maps for city shape of 1996 showed good similarities with each other through a morphology verification method. The model enabled us to evaluate the spatial expansion phenomena of cities considering boundary conditions, and also to simulate land use planning for rural areas in urban fringe.

The purpose of this study is to suggest the rural village model which is able to be applied to the rural village (re)development. The rural village model consists of five sector models land use model, residential unit model, public facilities allocation model, productive space arrangement model, road & green system model. The village model as a spatial structure needs modification/revision through the its application to various sites. The following are suggestions developed in the process of preparing a model for the Korean rural village. First, some indices presented in the land use model need to be further studied as the planning indices before implementing the rural village projects. Second, it is recomended that the image of a rural village needs to be created by developing the residential unit(6 households) as a planning development unit, And various residential unit models need to be suggested. Third, it is desirable to develop the double circulation system and green edge(1 m), and to introduce pedestrian road as much as possible for the amenity of the residential environment, Fourth, being located within walking distance from the existing village, new-introduced site should be developed as a interlinked and opened structure. The rural village model is useful in preparing the spatial structure for the village (re)development, and in finding the best design solution responsive to the conditions of a project site.

This study compared evacuation effectiveness between the conventional school auditorium plan and a suggested hypothetical plan that was generated by a mathematical model, which is commonly applied in the field of industrial engineering. Recent school buildings became much more complicated in floor planning due to new social needs and modern curriculum than the old days. Nevertheless, architect's approach to floor composition in terms of fire emergency evacuation planning, still has no relation to optimized effective but relies more on an conventional school planning. Therefore, since school buildings are much more likely to be exposed to any fire related events than any other building types, emergency exit effectiveness based on spatial composition has to be seriously evaluated with a scientific method. The algorithm, which acquires the number of persons in each spatial type(node) per floor and the minimum physical distance between spatial types(arc), can propose the most optimized spatial layout per floor regarding emergency evacuation event. Consequently, this study evaluated school's fire exit effectiveness focusing on auditorium area with the scientific tool and suggested the most reliable spatial layout regarding possibile emergency evacuation event.

This study compared evacuation effectiveness between the conventional school floor plan and a suggested hypothetical floor plan that was generated by a mathematical model that is commonly applied in the field of industrial engineering. Recent school buildings became much more complicated in floor planning due to the new educational system and modern curriculum than the old days. Nevertheless, architect's approach to floor composition in terms of fire emergency evacuation planning, still has no relation to optimized effective but relies more on a conventional school planning. Therefore, since elementary school buildings are much more likely to be exposed to any fire related events than middle school or high-school, emergency exit effectiveness based on spatial composition has to be seriously evaluated with a scientific method. The algorithm, which acquires the number of persons in each spatial type (node) per floor and the minimum physical distance between spatial types (arc), can propose the most optimized spatial compositing per floor regarding emergency evacuation event. Consequently, this study evaluated elementary school's fire exit effectiveness with the scientific tool and suggested the most reliable spatial composition per floor regarding possibile emergency evacuation event.

The purpose of this study is to establish a walking energy weighted ERAM model that can predict the pedestrian volume by the connection structure of the vertical and horizontal spaces within a three-dimensional building. The process of building a walking-energy weighted ERAM model is as follows. First, the spatial graph was used to reproduce three-dimensional buildings with vertical and horizontal spatial connection structures. Second, the walking energy was measured on the spatial graph. Third, ERAM model was used to apply weights with spatial connection properties in random walking environment, and the walking energy weights were applied to the ERAM model to calculate the walk energy weighted ERAM values and visualize the distribution of pedestrian flow. To verify the validation of the established model, existing and proposed spatial analysis models were compared to real space. The results of this study are as follows : The model proposed in this study showed as much elaborated estimation of pedestrian traffic flow in real space as in traditional spatial analysis models, and also it showed much higher level of forecasting pedestrian traffic flow in real space than existing models.

Recently, urban shrinkage due to low birth rate and aging population and the decline of local cities are causing a new urban problem of empty houses. This study examines the distribution of vacant homes using spatial panel data collected from 2015 to 2019 at local administraitve districts and estimates the factors of vacant house occurrence using a spatial panel model considering spatio-temporal dependency. As a result, the spatio-temporal dependence of vacant houses was identified and it was estimated using spatial panel model not OLS model. Based on the spatial panel model, it was found that the most influential factor in the occurrence of vacant houses was the housing-related factor. This result shows that policy considerations for housing supply are necessary for the management of vacant housing as well as population movement and poor infrastructure.

The access area, so called "core" in the housing block, makes a buffer zone between public open space and private interior space, as well as offers chances of communication for the users. Planning and design of this area, however, tend to be not attended, comparing with another spaces in the multifamily housing block. This paper is aimed at investigating examplary model European cases and, thus, finding out some positive and applicable planning skills for multifamily housing in Korea. This study covers following aspects; firstly, the important social meaning of core area was analyzed in comparison of Korea and Europe, secondly, intensive studies on the spots, visiting German, Austrian and Dutch cases, made it possible to grasp the prevailling tendency toward assessment of this area in the Continent, Thirdly, useful planning elements and skills by European examples for more user friendliness, more economization and raising the quality of spatial design and sequential experience were founded out with regard to various core types. and lastly, some concrete guidelines for planning are presented for the improvement of so far monotnousely designed core area in the local multifamily housing. Consequently those European cases made it clear that the planning of core area is closely related to the total design of housing blocks. This study maybe conducive not only to the planning of this area, but also further to the increase of the quality of life in multifamily housing.y housing.

Although the frequency of use for community facilities in rural villages is growing as well as the importance of the facilities for urban-rural exchange is being highlighted, study on spatial location-analysis of the facilities for such multi-purpose is not so much. This study aims to find the spatial distribution forms of community facilities in rural villages such as community center and rural-pocket park through location-analysis, in order to provide available data for selecting location in the future. As the study area, Sojeong-myeon, Sejong Special City was selected. This study conducted GIS analysis for criteria of the location-evaluation model developed in this study. This study introduced the concept of time-distance for accessibility analysis. This paper also used linear-consecutive scoring method(LCSM) as a scoring method of criteria and Analytic Hierarchy Process(AHP) method for weighting values of criteria. The application results showed that the new model can generate the intensity of community facilities according to spatial distribution and accessibility from cities to the facilities.
