This study aims to examine how residents' perception of Neighborhood in the surrounding area changes to the spatial configuration changes due to co-residential area development in old urban area, and find out the characteristics of the perception changes. The research findings are as follows: First, the results of the spatial configuration changes analyzed by Space Syntax Model show that the integration value is between 0.5 and 0.7, which implies that the development in the old urban area does not contribute to the establishment of hierarchy. When the development takes place with the renewal of streets with consideration of the urban context, however, the integration improves relatively. Second, the actual distance and accessibility due to the street network appear to influence the residents' perception of Neighborhood. After the development, the residents' scope of perception increases on average. Third, the changes in the integration value of the streets after the development appear to influence the residents' scope of perception of Neighborhood. It turns out that there are frequent changes in the residents' scope of perception in the surrounding area around the streets with large increase in integration value, and the perception scope also moves to the center.

The purpose of this study was to explore the influence of the topography and the neighborhood facility on the aged people's social network formation. The paper samples the aged people living in Changchun city located in a flat ground and Tonghua city located in a mountain region. Four selections of dwelling districts from the two cities are based on amount of the facilities maintaining the wealth and living area same to do the questionnaires. One hundred aged people are selected in the each dwelling district to fill out the questionnaires, and 386 valid questionnaires are finally obtained. The data obtained from the questionnaires are used to do some statistic analysis by using SPSS24.0 program. The results are shown as following: In the case of same amount of neighborhood facility for dwelling district, the aged people living in a flat ground use the facility more frequently and communicate more often with their friends and neighbors than the aged people living in a mountain region do, the social network forms more easily as well. In the other case of same topography dwelling districts, the aged people living in an abundant facility dwelling district use the facility more frequently and communicate more with their neighbors and friends than the aged people living in a mountain region do, so the social network forms more easily as well. Thus it can be seen that topography and amount of facility are significant influence factors of the aged social network formation.

For the identifying of spatial distribution pattern, Moran's Index(I) which has the range of values from -1 to +1 is common method for the spatial autocorrelation measurement. When I is close to 1, all neighboring features have close to the same value, indicating clustered pattern. Conversely, if the spatial pattern is dispersed, I is close to -1. And I closing to 0 means spatially random pattern. However, this index equation is influenced by how defining the neighboring features for target feature. To compare and understand the difference of neighborhood definition methods, fixed distance neighboring method and Gabriel Network method were used for I. In this study, these two methods were applied to two marine environments with water quality data. One is Gwangyang Bay which has complex geometric coastal structure located in South Sea of Korea. Another is Uljin area adjacent to open sea located in east coast of Korea. The distances between water quality observed locations were relatively regular in Gwangyang Bay, however, irregular in Uljin area. And for the fixed distance method popular Arc GIS tool was used, but, for the Gabriel Network, Visual Basic program was developed to produce Gabriel Network and calculate Moran's I and its Z-score automatically. According to this experimental results, different spatial pattern was showed differently for some data with using of neighboring definition methods. Therefore there is need to choose neighboring definition method carefully for spatial pattern analysis.

The purpose of this research was to establish a green-networks from the perfective of landscape ecology in order to improve the function of urban green spaces. The study site was Dalsu-Gu in Daegu City. This research consisted of three phases. In the first phase, field surveys were carried out in order to understand existing distribution pattern of green spaces in the study site. 533 green spaces surveyed in the first phase were classified into 7 patterns and 24 types. The total area of the green spaces in Dalsu-gu was 3,329ha. Specifically the area of the 'urban nature parks' type was 57.49% of the total area of green spaces in Dalsu-gu, and it was expected that 'urban nature parks' type can play important roles in the green-networks in Dalsu-gu. Two analysis with green spaces in 9 types including 'urban nature parks', 'rivers' and 'neighborhood parks' were performed to establish a basic network frame of the green-networks. In the second phase, 'mutual connectivity analysis' and 'mutual matrix analysis' were performed to select core green spaces of a green-networks using 'areas of each green space and a distance between each space' and 'a rate of green spaces and a rate of water permeable pavement'. The results of the second phase indicated that, in mutual connectivity analysis, large green spaces apart from each other were evaluated as having higher mutual connectivity than small green spaces near to each other. In mutual matrix analysis, the green spaces with higher mutual connectivity and the small green spaces near to each other were evaluated as having better mutual matrix. In the last phase, we structured a basic frame of the green-networks in Dalsu-Gu. The results suggested that the basic frame of the green-networks in Dalsu-Gu was composed on four green-network axes and its shape mirrored a cruciform(+) of northwest${\longleftrightarrow}$southeast directions and southwest${\longleftrightarrow}$northeast directions, The Duryu neighborhood park is at the central point of this green-networks.

도시화가 진행되면서 공원녹지에 대한 수요는 증가하고 있다. 공원녹지는 도시 내에서 사람들이 자유롭게 옥외활동을 할 수 있는 공간으로 인식되고 있어 중요한 공간이다. 공원서비스 권역은 거리를 기반으로 어느 범위까지 서비스를 제공하고 있는지를 보여주는 척도이다. 이 과정에서 접근성이라는 개념은 중요하게 작용하며 특히 보행은 사람의 가장 기본적인 이동수단으로서 공원 이용에 많은 영향을 미치고 있다. 하지만 현재 공원서비스 권역 분석은 소외지역을 발견하는 것에 중점을 두고 있어 수혜지역에 대한 세부적인 평가는 미비한 상황이다. 본 연구에서는 보행네트워크의 보행접근성을 바탕으로 공원서비스 권역을 평가하고자 한다. 공원서비스는 이용자가 직접 공원을 방문함으로써 발생하는 서비스로서 접근성이 이용 가능성으로 나타날 것으로 판단된다. 보행네트워크의 정량화를 위하여 본 연구에서는 공간구문론을 활용하여 통합도 값을 바탕으로 보행접근성 분석을 진행하였다. 통합도 값은 보행네트워크의 접근성 정도를 수치화하여 보여주는 지표로서 본 연구에서는 통합도 값이 높을수록 공원 이용 가능성이 높다고 해석하였다. 연구의 결과는 다음과 같다. 첫째, 분당구의 공원서비스 권역은 43%를 차지하고 있으며, 보행접근성이 높은 구간이 대부분 포함되어 있지만 일부 보행접근성이 좋은 구간은 제외되어 있다. 이는 도시계획 과정에서 주거지역과 상업 및 업무 지역이 우선적으로 지정되고 그 후에 공원녹지 지역이 선정되는 과정에서 나타나는 현상으로 볼 수 있다. 둘째, 분당구를 기준으로 공원서비스 권역 및 공원서비스 권역 내 보행접근성을 법정동별로 분류하였다. 개별 법정동 별로 차이가 나타나며, 이에 따른 공원에 대한 이용 가능성이 다르게 나타날 것으로 예상된다. 또한, 같은 도시계획 과정에서 만들어진 지역이라도 보행접근성에 따른 공원서비스 권역의 평가는 차이가 나타났다. 이를 활용하여 생활권 계획에 반영될 수 있는 개별 동 단위의 평가가 가능하며 추후 이를 반영한 공원녹지 정책에서 유용한 지표로 활용될 수 있다.

The purpose of this paper is to classify zones disrupting green spaces in city and to evaluate of their grades. The results are as follows; L There were 158 green spaces in Dalsu-gu. The 158 green spaces were classified 4 patterns and minutely classified into 9 types. The area of the 'nature park' type was turned out to be $70.1\%$ of the total area of green spaces in Dalsu-gu, then the type was considered as a important part of the green-network in Dalsu-gu. The 9 types such as 'nature park', 'river', 'neighborhood park' and so on were analysed with ecological indexes. 2. Based on the ecological indexes of 'ratio of the green space', 'features of the surrounding matrix' and 'travel distance of the wildlives' , zones disrupting green spaces were ranging widely and re-divided to 236 sectors. 3. The analysis results for classifying the grades were that grade I appeared over industrial complex and housing complex widely. On the other side, grade II and III appeared around or between nature park and neighboring park Consequently, it was necessary to consider the grade and make zones disrupting green spaces into green space for improving green network.
