In this study we suggest that the spatial correlation structure of the brain fMRI data be used to characterize the functional connectivity of the brain. For some concussion and recovery data, we examine how the correlation structure changes from one step to another in the data analyses, which will allow us to see the effect of each analysis to the spatial correlation or the functional connectivity of the brain. This will lead us to spot the processes which cause significant changes in the spatial correlation structure of the brain. We discuss whether or not we can decompose correlation matrices in terms of its causes of variations in the data.

머신러닝과 딥러닝 기술의 발달로 인하여 도시의 변화탐지에 이러한 기술을 적용하려는 관심과 시도가 증가하고 있다. 그러나 기존의 변화탐지와 공간정보 구축방법은 여전히 사람에 의해 수작업으로 수행되는 경우가 많아 비용과 시간이 많이 소요되고 있다. 또한 도시지역에서 건축물의 변화탐지를 효율적으로 수행하기 위해서는 많은 인원이 필요한 실정이다. 따라서, 본 연구에서는 포인트 클라우드에서 딥러닝 기술을 적용하여 공간정보 분야에서 활용도가 높은 도로, 건물, 식생의 객체를 분류하고 변화탐지를 수행할 수 있는 방법을 제안하였다. 실험 결과 약 92% 이상의 정확도로 도로, 건물, 식생을 분류하였으며 이를 통해 객체의 속성정보를 자동으로 구축할 수 있었다. 또한, 시계열 데이터가 구축된다면 제안한 방법론을 통해서 변화를 탐지할 수 있고 기 구축된 수치지도의 속성을 검수할 수 있을 것으로 판단된다.

본 연구의 목적은 우리나라 노동시장의 구조 변화에 따라 급속히 성장한 성인을 대상으로 하는 사교육 시장의 공간적 분포 특성을 분석하는 것이다. 이를 위하여 사교육의 대표적 기관인 사설학원의 수강생 중 성인을 대상으로 직업별(대학생, 직업인, 무직), 학력수준별(초졸, 중 고졸, 대졸)로 범주를 세분화하여 각 범주의 카테고리에 속하는 성인 학원수강생의 분포 특징을 분석하였다. 또한 이들의 지역별 분포 패턴에서 나타나는 공간적 함의를 파악하고자 Moran's I 값을 통해 공간적 자기상관성을 판별하였고, $G^*$통계량을 통한 핫스팟(Hot spot) 분석을 실시하여 공간적 군집 여부를 확인하였다. 아울러 학원유형별 성인 학원수강생의 분포와 인구 및 사회 경제적 설명변수와의 관계 도출을 위해 다중회귀분석을 수행하였다. 본 연구는 다양한 노동통계, 교육통계 지표를 제시함으로써 노동시장의 구조 변화와 성인을 대상으로 하는 사교육 시장의 관계에 대한 이해를 도모하였다.

In modern society, rapid environmental changes are occurring due to the complex interaction of various factors. Starting in 2020, the social environment is changing rapidly due to the impact of the pandemic, and the social and economic living environment is changing significantly not only in Korea but also internationally. In this trend, behavioral and spatial changes are occurring in response to changes in the architectural living environment. To analyze changes in behavior and space from an architectural perspective in response to changes in the social environment, first organize the concept and aspects of the pandemic that caused the change, examine the theory of the pandemic, and examine architectural responses to changes in the social environment. There is a need to analyze. Therefore, in order to architecturally review changes in the social environment due to the pandemic, the purpose of this study is to analyze the living behavior and space of major highrise residential complexes in the living environment and present new spatial alternatives in response.

Transformations of the urban spatial structure, from sub-area redevelopment to newtown development, results great influences upon existing urban condition and spatial configuration. The purpose of the study is to analyse the effect of the urban spatial configuration of Uijongbu city where experienced changes after newly development of city center and new residential area. The west part of the city where is limited in growth by military bases, ego U.S Army basecamp, were planned and established as the other axis of the city center since mid 1980's. After that new residential area which is located in far east of the city were also developed. Space syntax as a methodology has been adopted to conduct quantitative analysis which is able to interpret differences between sub-areas ; old city center, new city center, new residential area. The results of the analysis are follows ; 1) existing structure of the urban fabric, especially old city center, is sustained and intensified, 2) new city center which is west part of the city has failed to achieve organic spatial connection adjacent to old city center, 3) there is less spatial depecdency relationship between city center and new residential area where is identified as another small self-support city within the city.

Each class in remotely sensed imagery has different spectral and spatial characteristics. Natural features have relatively smaller spatial changes than spectral changes. Meanwhile, urban area in which buildings, roads, and cars are included is inclined to face more changes of spatial variation than spectral one. This study aims to propose the new urban complexity index (UCI) based on the 3D DWT computation of remotely sensed imageries considering these characteristics. And then we analyze relation between index and land cover map. The 3DWUCI values are related to class and the indices of urban area are greater than natural area. The proposed UCI could be used to express effectively the standard of urban complexity over a wide area.

본 논문에서는 토지피복도에서 공간구조를 검출하고 시계열 공간구조 변화를 검출하는 시스템을 제안한다. 서로 다른 시간의 토지피복도에서 패치를 검출하고 패치의 측정요소를 계산하여 공간구조 패턴을 분석한다. 검출된 시계열 패치에 대해 패치 매핑을 이용하여 유지, 생성, 소멸, 분할, 병합, 혼합적 변환 등의 변화 유형을 결정한다. 또한, 시계열 토지피복도의 패치 기반 공간구조 패턴을 이진으로 저장하여 변화를 추출하였다. 본 논문에서는 제안하는 토지피복도 공간구조 변화검출 시스템을 통해 해당 지역(도시)의 난개발 현상을 진단하고, 향후 도시공간구조의 재구축을 위한 계획수립에 근거 자료로 활용될 수 있음을 보여주고 있다.

The spatial form of architecture in the same era has its own common characteristic spatial form. This study is based on this proposition and is focused on how architectural spatial forms have been changed up to now after modern ages(from the beinging of 1900s to the early days of 1990s ; from early modern age, golden modern age, post modern, late modern architecture to recent experimental trend) and how architectural theories of spatial forms will be changed in the future is predicted.

In order to determine temporal changes of the urban landscape, interdependence and interaction among geo-spatial objects can be analyzed using GIS analytic methods. In this study, to investigate changes in the landscape structure of the Namyangju area, the size and shape of landscape patches, and the distance between the patches were analyzed with the Spatial Autocorrelation Method. In addition, both global and local spatial autocorrelation analyses were conducted. The results of global Moran's I revealed that both patch size and shape index transformed to a more dispersed pattern over time. Next, the local Moran's I of patch size in all time series determined that almost all patches were of a high-low pattern. Meanwhile, the local Moran's I of the shape index was found to have changed from a high-high pattern to a high-low pattern in time series. Finally, as time passes, the number of hot spot patches about size and shape index had been decreased according to the results of hot spot analysis. These changes appeared around the development projects in the study area. From the results of this study, degradation of landscape patches in Namyangju were ascertained and their specific areas were delineated. Such results can be used as useful data in selecting areas for conservation and for preparing plans and strategies in environmental restoration.

The purpose of this study is to investigate the changes of architectural characteristics of the rural houses in Jeju area for the last half a century. 72 houses in eight villages, which have been spontaneously renovated or added, were chosen as the rersearch samples. The subjects were classified into three groups-traditional, modernized, and contemporary houses-mainly by their construction years. Based upon these classification, the factors of change and continuation in building layout and spatial composition of dwellings have been investigated. As the results, Jeju rural houses show the tendency of the various and rapid changes in overall shape and spatial composition, but the traditional concepts of composition in plan has been maintained. Especially, the open structure of three-folded houses and the utilization of traditional floor system have been maintained as major design concepts to compose a house.
