The purpose of this study is to analyze the spatial characteristics of business-type-changed parcel in the Hongik-University commercial area, from the view point of commercial gentrification. A commercial gentrification occurs through a business-type-change in a spatial basic unit (microscopic spatial unit such as parcel) of an area which has not been considered in relavent policies and research. So, this study analyzed the spatial characteristics of business-type-changed parcels using the Cox's proportional hazard regression model. The main results of this study are as follows. First, as new developments in the adjacent area occur, the business-type-change probability increases. Second, by the commercial area division, the business-type-change probability is different. Finally, the accessibility is better, the probability is higher. These results could suggest that a consideration of the spatial characteristics form microscopic viewpoint is necessary to understand the commercial gentrification. And these could be used as basic data for a gentrification diagnostic and management system, which can predict gentrification from the view point of business-type-change on the basis of a parcel.

In recent years, the frequency and scale of the natural disasters are growing rapidly due to the global climate change. In case of the urban flooding, high-density of population and infrastructure has caused the more intensive damages. In this study, we analyzed the spatial characteristics of urban flooding damage factors using GWR(Geographically Weighted Regression) for effective disaster prevention and then, classified the causes of the flood damage by spatial characteristics. The damage factors applied consists of natural variables such as the poor drainage area, the distance from the river, elevation and slope, and anthropogenic variables such as the impervious surface area, urbanized area, and infrastructure area, which are selected by literature review. This study carried out the comparative analysis between OLS(Ordinary Least Square) and GWR model for identifying spatial non-stationarity and spatial autocorrelation, and in the results, GWR model has higher explanation power than OLS model. As a result, it appears that there are some differences between each of the flood damage areas depending on the variables. We conclude that the establishment of disaster prevention plan for urban flooding area should reflect the spatial characteristics of the damaged areas. This study provides an improved understandings of the causes of urban flood damages, which can be diverse according to their own spatial characteristics.

본 연구는 충청권을 대상으로 공간특성을 분석하고 쇠퇴지역을 도출하는데 목적이 있다. 쇠퇴지역 도출을 위해 쇠퇴지표를 선정하고 충청권의 시 공간적 지표자료를 가공하여 공간자료로 이용하였으며, 쇠퇴지역의 특성을 도출하기 위하여 공간적 자기상관을 적용하였다. 공간적 자기상관은 '공간'이라는 요인을 고려하여 공간특성을 도출할 수 있는 방법이다. 또한 쇠퇴지역의 특성 도출을 위해 경제학적 개념을 도입하여 정(+)의 값을 가지는 지역은 보완지역으로 부(-)의 값을 가지는 지역은 대체지역으로 구분하였다. 이를 통해 주변지역의 성장으로 인해 쇠퇴되는 지역과 주변지역의 성장으로 인해 함께 성장하는 지역 등의 특성을 도출하였다. 본 연구는 충청권 시 군의 쇠퇴지역 도출 및 특성을 분석함으로써 향후 재생계획 수립을 위한 의사결정을 지원하고자 한다.

본 연구의 목적은 GIS기술을 이용하여 적조의 시공간적인 분포를 분석하는 것이다. 적조에 의해 발생하는 피해는 적조 생물종에 따라 다양하게 나타난다 때문에 적조의 피해를 저감하기 위해서는 시-공간적인 적조 생물종의 분포특성을 파악하는 것이 중요하다. 이러한 관점에서 우리는 최초의 적조발생지역, 공간적 발생빈도, 적조의 이동 등을 분석하였다. 본 연구에서 사용된 공간자료는 적조 속보 보고에 의해 공간분포를 디지타이징하였고, 적조데이터베이스를 구축하기 위해 적조 생물종, 생물 밀도, 수온 등의 다양한 속성자료를 구성하였다. 적조의 시-공간적 분포 특성을 분석하기 위해 다양한 공간분석기법을 적용하였다. 이러한 공간분석 결과로부터 남해에서의 시-공간 적이 적조 공간 정보를 얻을 수 있었다.

Aging phenomenon is an important issue in Korea national policy. This aging phenomenon depends on the social and environmental characteristics of regions. Also aging phenomenon and regional characteristics have spatial dependency. The purpose of this study is to discover the spatial changes in aging population rate and to find local factors of regional aging phenomenon considering spatial autocorrelation. For spatial analysis of ageing phenomenon, local Moran's I and Geographically Weighted Regression (GWR) were applied. As the results, the most significant changes of aging phenomenon appeared between 2000 and 2005, and most of hot-spot regions (aged regions) were distributed in Jullanam-do and Jullabuk-do. The results of GWR (R-square: 0.681) shows that total fertility rate, the number of doctor per 1,000 people and forest area rate have positive relation with aging population rate, but the number of private academy per 1,000 people has negative relation.

도시쇠퇴와 공동화 현상을 방지하고 침체된 지역경제를 활성화시키기 위한 새로운 도시재생 패러다임이 등장하고 있다. 본 연구는 도시재생특별법에 제시된 쇠퇴기준과 공간자기상관 탐색을 기반으로 GIS 및 공간통계기법을 활용하여 도시쇠퇴 특성을 분석하는데 그 목적을 두고 있다. 광주광역시를 대상으로 하여 도시재생특별법에 제시된 쇠퇴 기준인 인구감소, 사업체감소, 노후건축물에 관한 지표를 적용함으로써 객관성을 확보하고자 하였다. 특히 GIS와 공간 통계기법을 적용함에 있어서 공간자기상관 탐색을 통해 도시쇠퇴 특성을 분석한다는 점에서 기존의 연구와 차별성을 지닌다. 전체적인 분석과정은 도시활성화지역 지정 기준을 원용하고, 공간탐색적 절차에 따라 단계적으로 추진하였다. 따라서 본 연구를 통해 제시된 공간통계분석 절차 및 도시쇠퇴 특성 분석의 결과는 대도시권 수준에서 도시쇠퇴 진단에 기여하고, 도시재생과 관련한 공간의사결정에 유용한 정보를 제공할 것으로 기대한다.

The purpose of this study is to grasp the spatial characteristics and consciousness structure for The Third Place through the empirical research, focused on housewives as the survey who spend many times in neighborhood. The four types as the consciousness structure are deducted, Nature-oriented type, Unusual experience type, Solitude enjoyment type, and Originality-oriented type. And the spatial characteristics related to the four types are deducted as the followings: Nature-oriented type contains the spatial characteristics as Wild space, Speculative space, Dotty occupation space, and Green way. Unusual experience type contains as Rambling space, Dynamic sojourn space, and Theme-plex space. Solitude enjoyment type contains as Anonymous private space, Encircling space, and Religious space. Originality-oriented type contains as Chatter space, Self development space, and Community space between families. The results of this study represent six characteristics on the third place, advocated by Oldenburg, and show housewives' various needs and concrete examples for the Third place in city.

This study aims at evaluating the spatial configuration of general hospitals in terms of Visitors' movement pattern. In doing so, the study deals with three hospitals which are recently built and are generally considered to show recent trends in their spatial configuration. First, the Space Syntax method is used in order to systematically describe and analyse the spatial configurations, and thus to find out the spatial characteristics of each hospital in terms of movement pattern. Second, the spatial characteristics reflected on the 1st floor plan are compared with the planning concepts considered at early stage of the design. It can be said that the concept of hospital street and the spatial hierarchy should be carefully taken into account and tested the spatial configuration by the completed floor plan in order to satisfy the planning concepts.

In this study, we propose a method to investigate topographic characteristics by applying machine learning which is an artificial intelligence analysis method based on the spatial data constructed using UAV and the training data created through spatial analysis. This method provides an alternative to the subjective judgment and accuracy of spatial data, which is a problem of existing topographic characteristics survey for officially assessed land price. The analysis method of this study is expected to improve the problems of topographic characteristics survey method of existing field researchers and contribute to more accurate decision of officially assessed land price by providing more objective land survey method.

Detection and identification of targets from remotely sensed imagery are of great interest for civilian and military application. This paper presents an algorithm for target detection in high spatial resolution imagery based on the spectral and the dimensional characteristics of the reference target. In this algorithm, the spectral and the dimensional information of the reference target is extracted automatically from the sample image of the reference target. Then in the entire image, the candidate target pixels are extracted based on the spectral characteristics of the reference target. Finally, groups of candidate pixels which form isolated spatial objects of similar size to that of the reference target are extracted as detected targets. The experimental test results showed that even though the algorithm detected spatial objects which has different shape as targets if the spectral and the dimensional characteristics are similar to that of the reference target, it could detect 97.5% of the targets in the image. Using hyperspectral image and utilizing the shape information are expected to increase the performance of the proposed algorithm.
