인간의 활동 영역과 도로의 확장으로 인한 생태공간의 손실과 단절은 생물다양성에 부정적 요소이다. 특히 토지의 이용과 피복이 급속하게 변한 도시의 시가화지역은 생태공간의 손실과 고립으로 야생생물의 서식이 어려운 지역이다. 또한 도시화에 따른 생태공간 손실과 단절은 생태계서비스에 부정적 영향을 미칠 수 있다. 그러므로 도시와 국토의 생물다양성 및 생태계서비스 증진을 위해 도시의 현황을 반영한 실용적 생태축 구축이 필요하다. 따라서 본 연구는 대구·경북권역 기초자치단체의 도시생태축 관련 공간계획 수립에 활용할 수 있는 생태공간의 연결성과 산림축을 분석하여 제시하였다. 생태공간 연결성은 대구·경북권역 31개 기초자치단체의 산림과 자연지역으로 구분하여 토지피복도를 활용하여 분석하였다. 그리고 대상지를 20,483개의 1km² 육각형 격자로 나누고 생태공간의 100m 이내 단절에 대한 복원 효과를 공간 군집화하여 복원 중점지역을 시각화하였다. 산림축은 100ha 이상 산림 1,534개를 연결하는 선형을 토지피복, 건축물 면적, 경사 등 지역 현황을 반영하여 도출하였다. 연구 결과는 생태공간의 연결성 개선을 위한 공간계획 및 목표 수립과 복원지역 선정의 기초자료로 활용할 수 있을 것으로 기대된다.

유럽 및 미국에서 항공산업의 규제완화는 항공사가 그들의 네트워크를 허브-앤-스포크 구조로 변경토록 하는 원천이 되었다. 최근에 나타나는 아시아 항공시장의 자유화 움직임은 이 지역 항공네트워크를 변화시키는 계기가 될 것이다. 이와 같은 환경변화로 인해 항공사와 공항 당국은 허브-앤-스포크 운영에 따른 상호 연결성을 개선하기 위해 그 개념을 정의하고 연결성 지수를 수립 운영하는 것이 중요한 이슈가 되었다. 본 논문에서는 연속 연결성지수(CICI, Continuous Indirect Connectivity Index)를 제안하여 유럽, 미주 및 아시아 지역의 주요공항들에서 항공사 스케줄에 따른 허브화 조정정도를 평가하고자 하였다. 연속 연결성지수는 세 부분으로 구성된다. 첫째 출발-도착 항공편 간 환승 편의성을 파악하기 위한 시간 연결성지수 설정, 둘째 항공편의 경유 거리에 의한 매력도를 나타내는 공간 연결성지수, 셋째 환승노선의 운항빈도에 의한 상대강도지수 도출 등이다. 본 논문에서는 연속 연결성지수와 환승객수 및 로그 환승률 간 인과관계를 분석하여 지수의 유효성을 증명하였다. 연속 연결성지수와 환승객수의 결정계수는 0.94, 로그 연속 연결성지수와 환승률의 결정계수는 0.69로 Danesi와 Doganis지수보다 높은 인과성과 우수한 설명도를 나타내는 것으로 분석되었다.

2020년 7월 공원일몰제 시행을 앞두고 도시자연공원구역 지정과 관련 법률 개정을 통해 서울시 미집행 도시공원의 실효 시점이 연장되었다. 그러나 미집행 도시공원의 개발이 여전히 가능한 상황에서 공원녹지의 추가적인 토지개발이 예상된다. 이 연구에서는 서울시 미집행 도시공원을 대상으로 향후 공원 내 사유지의 토지전용이 일어날 상황을 가정하고 예상되는 경관 연결성 변화에 따른 우선매입 대상지를 선정하고자 한다. 이를 위해 공원일몰제 시행 전과 후의 토지피복 변화와 생물의 이동능력을 반영한 4가지 경관투과성 시나리오(PB100, PB1, PA100, PA1)를 작성하였다. 이들 시나리오에 기반하여 Connectivity Analysis Toolkit의 전류흐름 매개중심성(current flow betweenness centrality) 방식으로 경관 연결성을 계산하고 미집행공원별 전류흐름 매개중심성 순위 변화를 비교하였다. 분석결과 공원일몰제 시행 이후 상황을 반영한 PA1과 PA100 시나리오에서 서울시 남부에 위치한 미집행 도시공원의 전류흐름 매개중심성 순위가 크게 감소하였고, 한강을 통한 이동이 어려운 PA1 시나리오는 북한산 인근 공원에서 전류흐름 매개중심성 순위가 크게 감소하는 것을 확인하였다. 향후 미집행 도시공원의 환경적·생태적 기능을 고려한 매입방안 모색에 있어 본 연구결과가 도움이 될 것으로 기대된다.

This study examines the correlations of crime-prone locations with the urban space configuration in residential district. CPTED(Crime Prevention Through Environmental Design) is applied to this study and it is intended to control the architectural environment in order to restrain criminal activities. For this reason, an objective analysis for explaining the spatial characteristics of the places where the crimes have occurred is more important than statistical and descriptive approach for analyzing the criminal data. Visibility graph analysis (VGA) supports the CPTED theory in this study for objective interpretation of crime-prone locations and quantitative analysis for built environment. The comparative analysis on object streets and areas are used and the results are followings. The analysis by streets showed that street crimes are correlated with connectivity, control, integration, and integration(r=3) and burglary cases are correlated with control. The analysis by areas showed that street crimes are correlated with connectivity and integration. The T-tests results of crime area and whole area showed that street crimes are correlated with integration and burglary cases have negative correlation with connectivity. Several localized environmental design for crime prevention are also proposed on the basis of this study.

In order to overcome the problem that outdoor and indoor spatial information service are separately utilized, an integration service system of spatial information that is linked from outdoor to indoor has been implemented. As a result of the study, "0001.xml" corresponding to the file index key value, which is the service connection information in the building information of the destination, was extracted from the prototype verification of the system, the search word of 'Kim AB' was transmitted to the indoor map server and converted from the outdoor map service to the indoor map service through confirmation of the navigation service connected information, using service linkage information and search words of the indoor map service was confirmed that the route was displayed from the entrance of the building to the destination in the building through the linkage search DB (Database) table and the search query. Therefore, through this study was examined the possibility of linking indoor and outdoor DB through vector spatial information integration service system. The indoor map and the map engine were implemented based on the same vector map format as the outdoor map engine, it was confirmed that the connectivity of the map engine can be applied.

In the spatial configuration of room-to-room art museums, openings and walls are important physical factors, and openings are a medium for connecting spaces. Also, by spatially composing walls and openings, spaces can be connected visually and physically, and movements and directions may vary depending on the location or size of walls and openings. In this study, 5 museums are investigated: Sainsbury Wing in London, Gemaldegalerie In Berlin, Alte Pinakotkek in Munich, Neue Pinakothek in Munich, and Staatsgalerie Stuttgart in Stuttgart. Using DepthMap program, the characteristics of visual-spatial composition of each museum are derived by comparing the Connectivity, Visual integration, and Isovist maximum radial. From an analysis of spatial distribution, a relationship with visibility is investigated. The results of this study showed that the combination of visual axial lines affect the spatial configuration of the room-to-room museums. Depending on the location of opening, the museums can be classified as follows: 1) Museums with the 1st visual axial line and the 2nd and 3rd auxiliary visual axial lines ; 2) museums with several equal visual axial lines; and 3) museums with only center axial line.

Smart City operates with the purpose of solving urban problems. The important thing in smart city operation is that spatial information must be managed at a high level. In addition, it has the characteristics of being managed by one platform. This study presented the core value dimension of smart city based on analysis of various domestic and overseas smart city operation cases. Smart cities are basically operated based on spatial information, and the higher the level of spatial information, the more smart city services can be connected and managed in an integrated manner. The performance dimension of smart city core values presented in the study includes prosperity, personalization, convenience, accuracy, sustainability, safety, environment, integration, etc., and there is a connectivity dimension, a concept that can be managed in an integrated manner. This study will be useful for empirical research on smart city performance dimension design and surveys based on case studies. It will also help field managers who develop, operate, and manage smart cities when quantifying performance dimensions.

In this paper we discuss the terms "exo-spatial design," "solar carving," and "bridging" as strategies for creating more socially connective tall buildings. As a typology, high-rise residential buildings have a unique set of challenges to becoming fully activated urban participants in the cities in which they are located. While there is a general recognition and appreciation that tall buildings provide identity to a city, there is often criticism of how they relate to their surroundings. Critics have posited that tall buildings are insular and foreboding by their very nature. This paper explores several design avenues for architects to consider in order to improve the social aspect of tall buildings. As all cities become taller and denser to accommodate growth, the need to design social space in, on, and around tall buildings must be continually examined if we are to have cohesive urban fabric that supports communities.

The purpose of this study is to show the relation of the change between spacial structure and social conditions of rural area. The spacial structure change of Asan city was analyzed using Space Syntax, and multiple regression analysis (dependent variables: connectivity, global integration, local integration / independent variables: population, household, farm population, farm population of 65years old and over, farm household, part-time farm households, cultivated land) was accomplished. As th result, that the increase of connectivity is related to the increase of population and farm population of 65years old and over and the decrease of farm population, and the increase of local integration is related to the increase of farm population of 65years old and over was showed. However, that global integration is not related to change of social conditions was proved.

According to glowing computing capacity, software in remote sensing has supported diverse processing interfaces from batch interface to high-end user interactive interface. In this paper, component based visual modeler is developed to process batch jobs for high-end users as well as novices. Visual modeler arranges several node groups which are categorized according to their purposes. These nodes carry out elemental unit processes and can be grouped to model. The model represents user specified job which is composed diverse nodes. User can organize models by connecting diverse nodes according to data flow model specification which rules node's connectivity and direction, etc. Furthermore, user defined models can be together to organize much more complex and large model.
