This study aims to examine the characteristics of the user experience of New Town neighborhood parks and explore issues that diversify the experience of the parks. In order to quantitatively analyze a large amount of park visitors' experiences, text-based Naver blog reviews were collected and analyzed. Among the Phase 1 and 2 New Towns, the parks with the highest user experience postings were selected for each city as the target of analysis. Blog text data was collected from May 20, 2003, to May 31, 2022, and analysis was conducted targeting Ilsan Lake Park, Bundang Yuldong Park, Gwanggyo Lake Park, and Dongtan Lake Park. The findings revealed that all four parks were used for everyday relaxation and recreation. Second, the analysis underscores park's diverse user groups. Third, the programs for parks nearby were also related to park usage. Fourth, the words within the top 20 rankings represented distinctive park elements or content/programs specific to each park. Lastly, the results of the network analysis delineated four overarching types of park users and the networks of four park user types appeared differently depending on the park. This study provides two implications. First, in addition to the naturalistic characteristics, the differentiation of each park's unique facilities and programs greatly improves public awareness and enriches the individual park experience. Second, if analysis of the context surrounding the park based on spatial information is performed in addition to text analysis, the accuracy of interpretation of text data analysis results could be improved. The results of this study can be used in the planning and designing of parks and greenspaces in the Phase 3 New Towns currently in progress.

This study modified and applied the ecological network(Indicator 2) from the City Biodiversity Index(CBI) to be tailored to Korea. It is calculated by utilizing a biotope map and a land cover map. The ecological network of Gyeryong-Si was 13,713,703(33.8%) with the biotope map and 17,686,966(37.9%) with the land cover map. The result of the biotope map was lower than the land cover map. The ecological network of Goyang-Si was 4,961,922(4.9%) with the biotope map and 4,383,207(3.7%) with the land cover map. The result of the land cover map was lower than the biotope map. As a main result of the research, an error was discovered in which, when calculating the ecological network, the types of the military unit facilities were distinguished into a special area on the biotope map and into an urbanization promotion area and a forest area on the land cover map. In the case of a middle-classified, land cover map, the land use in the surroundings of the forest area was not subdivided. An error in the development area expressed as a forest green was discovered. When selecting the natural elements, too, regarding the types of artificially-created rivers, artificial ponds, and artificial grasslands, etc. on a biotope map, the exclusions were necessary. Regarding the natural, bare ground on a land cover map, there was a need to calculate by including the natural elements. It was judged that, in the future, the ecological network in the unit of the entire nation can be analyzed roughly by utilizing a land cover map. It was judged that, in a city having a biotope map, the calculation of the ecological network utilizing a map of the present situation of the urban ecology will be a more accurate diagnosis of the present situation.

This study aimed to classify damaged lands, to find what are the damage factors affecting the studied area, and to present a prescription in order to provide some benefit for the restoration of Regional Ecological Network at Chungnam province. Finally we classified damaged lands from 1st to 4th damaged lands according to relative intensity of damage. The main damage factors for the First Damage Lands were humus horizon, soil hardness and plant species richness. In the Second Damage Lands, those were soil hardness, plant species richness, number of plants and dominant plant species. In the Third Damage Lands, those were humus horizon, soil hardness, plant species richness, number of plants and dominant plant species. In the Fourth Damage Lands, those were humus horizon, organic matter, soil hardness, EC, T-N content, plant species richness, number of plants and dominant plant species. In every cases, the damage of soil and vegetation was originated due to development carried out by human being. The changes in soil condition were not big enough for it to affect plant growth, however, degradation of vegetation was still severe.

We implemented ecological linkage assessment, through the connection components of the urban forests, rivers and parks, for the ecological connection of the urban parks which are standing out as the core of the urban green networks, so as to suggest basic data to compare, evaluate and improve urban green networks, as a basic study for the evaluation of the ecological connectabilities between the cities. For the ecological linkage assessment, we analyzed to see if the urban parks of Goyang, Ansan and Yongin, which are the subject cities, are actually ecologically connected with forests and rivers, using distance and roads, which are physical connection elements, in consideration of the mobility of the wild animals, and greening ratios and impervious pavement ratios, which are ecological connectabilities in consideration of the ecological values. The overall result of the ecological linkage assessment the physical connection elements and the ecological connection elements shows that the ecological green network ratio through direct connection states is 36.62% in Goyang, 42.55% in Ansan and 64.00% in Yongin, respectively, giving the ecological connectability ratio of less than half, with the average urban ecological green network ration of 47.72%. The comparison result of the ecological connectabilities between the object cities employing the connection elements indicates that when you set up green networks, you should consider together the physical connection elements, such as the roads, which will lower the ecological connectabilities - rather than do it simply based on areas and distances - while the ecological connection elements with the forests and the streams should be reinforced, so that the ecological connectabilities of the urban parks may be enhanced.

This is the urban design master plan for the Public Administration Town. The project proposes a newly configured city, where environmental and democratic principles are expressed in the shape of the urban fabric. To achieve the goal, the concepts of 'Flat City, Link City, and Zero City' were introduced. These concept show "Space fabric arrange, connection and material circulation and flow from ecological landscape". 'Flat City' shaped the government buildings into an iconic plane, and democratic society. The iconic plane's surface extends across the whole city, creating an expansive public park, which is easily accessible, and open to nature. 'Link City' connects governmental agencies to enhance their function and interactions. Government facilities, parks and green spaces, cultural facilities, commercial zones, and residential districts areas create an interconnecting network. 'Zero City' has integrated infrastructure systems to reuse waste, reduce pollution, and provide essential city functions. It creates a new wildlife habitat, making 'Zero City' a good neighborhood. This proposal was made to integrate historical, regional, nature experiences with various approaches in architecture, city, and landscape architecture.

본 연구는 2016년부터 2017년까지 한국 정부가 선정한 다수의 도시재생사업 중 수변공간 관련 사업을 선별하여 세부내용을 살펴보고 수변공간 도시재생사업의 거버넌스 특성을 분석한다. 도시재생사업에서 거버넌스는 사업의 성패를 가르는 핵심 요소로 대두되고 있다. 특히, 협업을 통한 민간 커뮤니티의 역할과 주민참여는 더욱 중요한 비중을 갖게 되었다. 본 연구는 Tallon(2013)의 도시재생 거버넌스 네 가지 형태-관주도(top-down), 주민주도(bottom-up), 시장주도(market-led), 지주주도(property-led) 재생을 기준으로 도시재생사업 활성화계획의 세부내용을 분석한다. 향후 도시재생사업의 추진 및 시행단계에서 거버넌스의 역할이 제대로 작동할 수 있도록 시사점을 제공하고자 한다. 연구의 공간적 범위를 수변공간을 한정하여 분석한 결과 총 20개의 도시재생사업이 도심 내 하천변과 해안가를 활용하여 추진되고 있었다. 구체적인 사업의 형태로는 (1) 생태하천복원, (2) 역사문화자원을 연계한 수변관광지 개발, (3) 수변네트워크 녹지 산책로 조성 (4) 항구 기반 수변도시개발 및 도심재생, (5) 섬의 이점을 활용한 수변경관사업, (6) 조선업 침체지역재생 등이 있었다. 한국의 수변공간 도시재생사업은 가장 일반적인 도시재생방식인 '관주도'로 진행되고 있었다. 그러나 지역의 권한과 역할을 강화하고자 하는 노력은 우선시되고 있었다. 또한, 관계부처 및 공공기관과의 파트너십 구축을 통한 도시재생사업의 효과성 향상을 도모하고 있었다. 특히, 부산시 영도구와 경상남도 통영시의 도시재생사업에서 협업의 노력이 두드러지게 나타났다. '마을만들기'와 같은 주민주도의 도시재생방식은 '주민참여협의체'를 통하여 일부 반영되고 있었다. 예를 들어, 서울시 도봉 노원구, 인천시 부평구, 경상남도 김해시, 부산시 영도구 등이 해당한다. 그러나 구체적인 실천 방안을 통한 주민주도 도시재생 거버넌스를 구축하는데는 부족함을 보였다. 더불어 민간투자를 유치하는 시장주도의 도시재생 접근은 찾아볼 수 없었다. 도시재생사업의 장기적이고 통합적인 특성을 고려했을 때, 안정적인 도시재생사업 추진을 위한 재원 마련에 대한 지속적인 노력이 요구된다.

Urban parks are public spaces that provide various services for any urban resident to use and enjoy. Parks should be fairly distributed so that the urban parks can be equally used amongst different regions, generations and classes. Researches on spatial distribution of urban parks have been continuously conducted from the past based on the principles of fairness with variety, and it was evident that their techniques have become more elaborate and sophisticated. Yet, there have been limitations in the analysis of residents who are the main users of the urban parks. The research done so far was unable to apply the real number of the residents and it was carried out by only classifying and analyzing the population by the same scale(grid in the same sizes), postal(zip) code and administrative district. The actual population that resides within the usable range of urban parks was not used. This study analyzes and evaluates the spatial distribution that the residents can use on foot, by utilizing the service areas and the residents' registration data by addresses. In this study, to analyze the square measure of the service areas of neighborhood parks in Daegu Metropolitan City and the number of residents within and outside of the service area, network analysis techniques were employed and the residents' registration data were utilized. Major findings were that the Square measure of service areas of neighborhood parks turned out to be 31.23% of the square measure of the residential areas and also, that only 43.03% of the population of the Daegu Metropolitan area lives within the service areas of the neighborhood parks.

This study is an attempt to seek ways to revitalize the main streets in local city with regard to urban regeneration. It focuses on the case of Myeong-dong Fashion Street located in front of Cheonan Station, which recently lost its vitality. In order to explore causes of the decline and solutions for restore, this paper investigate the concerned urban area by approaching through three different aspects: physical and environmental aspects, social and economic aspects, historic and cultural aspects. In addition, the street visitors were surveyed on their visiting patterns, priorities and discontents about the components of street, and preferences for its restoring, etc. The investigation resulted in following findings and proposals. In physical and environmental dimension, it is needed to create legal incentives for encouraging local residents to develop their own district, and suggested to plan green space for relaxation and cultural arts space by using existing buildings, along with the expansion of public parking. In regard of social economic aspects, it is proposed to give each street specialized commercial theme. At the historic and cultural level, it is suggested to plan the pedestrian network which links the Fashion Street with surrounding historic elements.
