Urban transit, which takes an important role of traffic volume, is operated in four different urban communities and constructed in two urban communities. However, the urban transit of each communities has different system in operation and construction. It is not efficient to construct and operate. Furthermore, is difficult to maintain urban transit system. In this paper, the standardization of power supply system for urban transit has been performed to solve above problems.

The purpose of this study were to compare the community attachment between rural and urban communities, and suggest directions for community development plans of rural and urban communities in Korea. The data for this study were collected from two communities(n=285), one from Gochang representing rural community, located in Jeonbuk province(n=142), and the other from Suwon city representing urban community located in Gyunggi province(n=143), utilizing questionnaire. The major finding of this study were as follows; 1) Community attachment was significantly higher in community than in urban community, and the linear development model was more appropriate to explain the results of the study. 2) Community attachment appeared to be significantly related to social bonds, community participation, social trust, community economical activities, and social and cultural environment. 3)In general, determinants such as number of acquaintances, price of cultural heritages of residence, trust for local government, good traffic environment, job satisfaction, etc. explained 55.5% in rural and urban communities.

최근 도시재생 및 사회적 경제 등의 분야에서 도시 공동체가 주목받고 있다. 지금까지는 도시 공동체의 이상적 대안적 성격에 관심이 있었으나, 도시 공동체의 발전을 위해서는 현실의 공동체에 대해 구체적으로 분석하고 이를 통해 과제를 도출하는 것이 필요하다. 이러한 문제의식 하에, 본 논문에서는 최근 공동체 활동이 활발하게 전개되고 있는 대구광역시 동구 안심지역 주민들을 대상으로 그들의 사회경제적 특성, 지역사회에 대한 공동체 의식, 지역에서 이웃과 맺고 있는 관계와 공동체 활동에 참여하는 것과의 관계를 분석함으로써, 도시 공동체의 현황과 과제를 고찰하였다. 분석 결과 이 지역에서는 중산층, 고학력, 아파트 거주자들이 주로 참여하였으며, 이웃과 사회적 관계를 활발히 맺는 경우가 그렇지 않은 경우보다 참여가 활발하였다. 이러한 공동체 활동의 특정 계층 지향성은 다른 주민의 정보 접근을 제한하고 이는 참여 제한으로 이어지며 배제가 일어나는 원인이 될 수 있으므로, 본 논문에서는 계층 간 보다 개방적인 느슨한 연대가 필요하다고 제안한다.

Ant communities are well suited for monitoring changes in ecosystems. Although numerous studies have examined the responses of ant communities to environmental disturbance, relatively few long-term studies on ant communities have been undertaken in urban environments. We examined species richness in nine urban parks in Hiroshima, Japan, and compared the survey results with data collected at the same sites by using the same methods in 1999. In both surveys, total of 25 species was recorded: 23 species in 1999 and 20 species in 2012. Non-metric multidimensional scaling analysis revealed that the ant communities consisted of two distinct groups, which could in turn be characterized by three patterns of ant community changes in between the two groups. The first of these community change patterns was characterized by a shift within group 1, but the number of species remained constant (approx. 10 species). The second pattern was characterized by a shift within group 2, but the number of species remained low (approx. 4 species). The third pattern was characterized by a shift from group 1 to group 2 as the abundance of Linepithema humile (Mayr) increased over time. Unlike the first and second patterns, the number of ant species in communities of the third type decreased significantly. These findings suggest that L. humile has a marked effect on the species diversity of indigenous ant communities in urban environments.

New urbanism is a school of urban development that combines residential, commercial, and civic land uses in a dense urban fabric of carefully prescribed form. Its advocates claim that New Urbanist developments are superior to prevailing urban development patterns on social and environmental sustainability. Its critics, however, argue that New Urbanism developments do not measure up to the social and environmental ideals and are, in some cases, just another form of urban sprawl. The goal of this study is to evaluate various criticisms of New Urbanist communities. This paper used empirical evidence to determine the performance of New Urbanist developments on the broader spatial and social context as opposed to the internal characteristics of the communities using GIS indicators. The results showed that the communities did not meet conventional criteria for New Urbanist ideals.

Purpose : This research aims to present policy plans for community vitality in the field of the urban regeneration project by analyzing aspects for vitality via domestic and abroad city policies and cases. Methods: The research method works as follows: The first step is 1) to introduce the concept of evaluation matrix to analyze cases of urban generation, 2) to apply to the proposed evaluation matrix, and then 3) to analyze communities' decline diagnosis, counterstrategies, and promotion process. And the second step is to draw features and evaluation of cases and to present the policy plan for communities' vitality with the urban regeneration project in South Korea via a comprehensive analysis. Result : This research confirmed the fact that when different sectors is expanded toward a mutual cooperation, communities are vitalized, having a mutual effect on other related sectors by taking a part in the community positively. Especially in the base of each characteristic and estimation, when various activities and socio-economic programs with residents are promoted in the integrated system, communities are successful. Through this results we present four policy plans for community vitality of the urban regeneration project in South Korea.

본 연구는 서울시 유동인구조사자료를 토대로 5개 생활권역의 보행특성을 비교 분석하였다. 우선 권역별로 총 보행량, 시간대별 보행량, 조사지점 속성에 따른 보행량의 차이를 분석하고, 다중선형회귀분석을 통해 평일과 주말보행량에 영향을 미치는 요인을 규명하였다. 분석결과, 대부분의 권역에서 중앙선, 버스정류장, 횡단보도가 있는 경우 유동인구가 증가하였으나, 도심권에서는 반대의 현상이 나타났다. 모든 권역에서 상업지역은 보행의 유발요인인 반면, 경사로는 보행의 방해요인인 것으로 나타났다. 회귀분석 결과에 의하면 다양한 통행특성지표, 토지이용지표, 사회적지표 및 조사지점 속성이 유동인구에 영향을 미치는 것으로 나타났다. 유동인구와 상관성을 보이는 변수는 권역에 따라 다소 상이하였으며, 영향을 미치는 정도도 다름을 확인할 수 있었다. 본 연구는 보행량을 종속변수로 하여 영향요인을 규명한 것으로 향후 보행환경 개선을 위한 정책수립시 기초자료로 활용할 수 있을 것이다.

In April, 2020, amid widespread fear of a second wave of infections of the novel coronavirus in China, local authorities in Guangzhou cracked down on the city's black population, resulting in mass evictions of Africans. The incident raises several questions about racism in China. How should we interpret this heavy-handed treatment of black people? Was this an isolated incident? What motivated such operations? In this article, I explain social control of Guangzhou's African communities as a problem of municipal politics. What underlies the government's heavy handed approach, I argue, are those communities' ties to rurality, which constitute a roadblock in the city's urban upgrade. Using Dengfeng Village, one of the best known African communities in China, as a case study, I show that efforts to upgrade the area by the local state and the real estate industry were frustrated by the community's status as an urban village. Africans, whom Chinese have historically associated with rurality, are seen as contributing to a space that has long been stigmatized as a spatial manifestation of rural people's lack of self-discipline. To better reveal the interconnection between social control and urban politics, I place official action in context of the history of the community's formation and the lived experience. This analysis of Dengfeng applies to various extents to other major African communities in Guangzhou.

The study was aimed to understand the ecological status of the Maebongsan urban forest in Cheongju-si through investigating the vegetation, soil characteristics, and soil microarthropods. Phytosociological analysis for twenty plots revealed that the plant communities were classified into Pinus rigida community, Robinia pseudoacacia community, Castanea crenata community, Quercus acutissima community, Pinus strobus community, Pinus koraiensis community, and Larix kaempferi community. The importance value showed that afforestation tree species like Castanea crenata, Robinia pseudoacacia, and Pinus rigida dominate the urban forest. DBH analysis indicated that although the plant communities seem to be under the succession to Quercus forest, the dominance of Castanea crenata and Robinia pseudoacacia might still persist for several more decades. The properties of soils from the plant communities showed that loamy sand and sandy loam in soil texture, low organic matters, and severe acidification. The abundance of soil microarthropods were not different among the plant communities except Castanea crenata community and Pinus koraiensis community. The two communities showed especially low abundance of collembola and acarina. Thus, we can say that Castanea crenata community and Pinus koraiensis community seem to have been influenced strongly by anthropogenic activities.

This study was designed to present a river model with an aim at restoring the ecosystem and improving the landscape along the urban rivers on the basin of the Namhan river, a core life channel for the National Capital region. The revelation of botanical status, transition trend and correlation of plants might lead to providing the urban river restoration projects and ecological river formation projects with basic data for a model of ideal aquatic ecology and landscape. The outcomes of this study could be summed up as follows: 1. Communities of Juglans mandshurica, Cornus controversa and Fraxinus mandshurica constitute the main portion of flora at or around uppermost branch streams of the River Namhanis harbored mainly in and around small brooks 2. Typical terrestrial forest communities formed around the River Namhan are composed mainly of Larix leptolepis, Pinus rigida, planned forestation of Pinus koraiensis, Quercus acutissima, Quercus variabilis and Pinus densiflora. 3. The analysis into terrestrial environment of plant communities showed a high content of $P_2O_5$, typical communities found in the artificially disturbed land Finally, it seems also desirable to continue to make every exertion to explore the relationship between fluvial and terrestrial ecologies with a purport of building up a model of natural streams in urban area based on the surveyed factors for plant life, forest communities, soil and landscape and, moreover, on the forecasting for overall influences derived from the relation upon the ecosystem.
