Due to recent climate change, neighborhood parks are recognized as being important not only for its role of being a critical factor in improving the quality of urban landscapes, but also for its ecological values as a CO₂ storage. This study aims to identify carbon stocks of trees as a ecological value of neighborhood parks in Seoul, and to suggest soil environment management measures for value enhancement. The subjects of this study are Neulbot, Geoyeo, Gyeryong, Onsu, and Junggye Neighborhood Parks. Literature and field surveys were conducted as the research method of this study. The survey period was from September 11, 2017 to September 30, 2017, and six investigators conducted on-site surveys for each park five to six times. The categories of the survey were a total of 12 items in 4 indicators of land use, planting characteristics, CO₂ storage and soil environment. As a result, first, the land use of the neighborhood parks was mostly the planting area, and even the soil of the facility area had carbon storage effect as there are unpaved areas such as playgrounds, squares, and trails. Second, the planting environment showed good CO₂ storage as the trees planted in the neighborhood park had an average of 11 species, broad-leaved tree-centered planting and multi-layered structure, and a high average DHC. However, in the case of a specific park, there were only 5 species of trees, and the CO₂ storage were low due to the lack of coniferous trees and lower plantings. These environment was correlated with a simple and monotonous landscape due to the lack of diversity in the landscape. Third, the amount of CO₂ storage was increased by the type of planted species and the wide of DHC rather than the planting area. Therefore, the management plan for promoting the growth as well as the species was found to be important. Fourth, by surveying the soil environment as a management plan to increase ecological value, it was found that the hardness was too high due to trampling effect, which resulted in low humidity and poor landscape. In order to prevent pressured soil, access to the trail and the planting area should be restricted for certain periods of time, and a management plan should be established to improve air gap blasting and irrigation for pressured soil. This study was measured the ecological value of neighborhood park to improve the quality of the urban landscape, it was found that the important correlation of the quality of the CO₂ storage and landscape. In order to promote continuous ecological value in the future, it was found that the Urban Landscape Management Plan requires a direction for setting and managing CO₂ storage indicators as a goal.

서울과 베를린의 근교 녹지를 대상으로 역사적 변천 과정 및 특징을 도출하고 두 도시 간의 유사성과 차이점을 비교함으로써 도시의 발달 과정 속에서 나타나는 가치를 해석하고 정립하고자 하였다. 서울과 베를린의 근교 녹지는 지형적으로 도시 외곽에 위치하고 있으며 환상형의 모양으로 도시의 경계로서 및 남북생태축으로서의 역할을 수행하고 있다. 또한, 개발제한구역·항속림 계약과 같은 제도에 의해 규제되면서 도시의 생태자원을 보존하는 기능을 수행해 왔다. 마지막으로는 서울과 베를린의 근교 녹지는 공공 이용 문화 공간으로서 도시민들의 여가휴양을 위해 활용되어지고 있는 유사점이 있었다. 그러나, 서울은 산으로 베를린은 숲으로 구성되어 있다는 지형적 차이가 있었으며 산림보호를 위해 서울은 공공이 주도하고, 베를린은 시민보호 운동으로 시작되었다는 점에서는 그 차이가 나타났다. 또한 근교 녹지 활용 측면에서도 서울은 서울의 산을 하나의 둘레길로 연결하여 서울의 정체성을 수립하고자 한 것에 반해 베를린은 8개의 광역화 공원으로 구분하여 차별화 되게 조성하였으며 지역관광 및 경제활성화의 수단으로 활용하면셔 지역 문제 해결의 플랫폼으로서 활용코자 하였다. 종합해보면, 서울과 베를린의 근교 녹지는 지속가능한 도시 발전의 목표를 위해 물리적·인지적으로 역할을 수행하고 있음을 알 수 있었다. By deriving historical transformation processes and characteristics and comparing similarities and differences between the two cities in the suburb green areas of Seoul and Berlin, we interpreted and established the values that appear in the development process of the city. The suburban green areas of Seoul and Berlin are located outside the city and serve as the physical and ecological boundary of the city in a ring shape. In addition, it has preserved urban ecological resources while being regulated by systems such as zoning and sustainable forest management. Lastly, the green areas in the suburbs of Seoul and Berlin have similarities that both were used for recreation by urban residents as public and cultural spaces. However, there was a topographical difference that Seoul was composed of mountains and Berlin was composed of forests. Also, forest conservation movement was led by the government in Seoul, while it began as a public movement in Berlin. In terms of the use of suburban green areas, Seoul established its identity by incorporating mountains into a single Dulle-gil, while Berlin divided its green areas into eight big parks and used as a means of regional tourism and economic revitalization. Taken together, it can be seen that the suburban green areas of Seoul and Berlin play a physical and cognitive role for the goal of sustainable urban development.

This study suggests a direction for local-led regeneration through the use of governance-based business in the face of the crisis of the times of the disappearance of local cities in Korea. As for the research method, the characteristics of facilities, programs, operators, major contents, and financing were analyzed for 4 cities in the case of regional creation in Japan. As a result of the analysis, the types of governance-based business utilization were divided into four types: ‘facility-oriented’, ‘content-oriented’, ‘financial-oriented’, and ‘human infrastructure-oriented’. There was a differentiation in the business utilization approach according to each type, and it was confirmed that there was a possibility of application and expansion depending on the infrastructure of the exiting region. In addition, it was confirmed that it should be considered as a means of revitalizing business through the establishment of local community-based governance in the recent local and urban regeneration in Korea. In summary, in order to respond from the national initiative to the regional initiative, it is necessary to develop various governance-based business utilization models that take into account local resources, local residents, and business types in a variety of ways and to increase the reality.

This paper asks what the Selection Attributes of urban open space are which carries out a role as an Urban Entertainment Destination. Case studies have chosen the Cheonggyecheon Waterfront, Seoul Forest Park, Seonyudo Park and Banpo Hangang Park as the representative open spaces in Seoul. The methods of study are observation investigation, a literature investigation and the survey to 233 visitors that conducted the ANOVA analysis and Regression analysis by SPSS 18.0. As a result, first, the urban open space in Seoul has had 8 elements of UED; Landscape, Multi anchoring, Contextual links, Programmability, Community, Branded identity, Security and Service. Second, they are being used not the neighborhood type but a wide area type. Third, Landscape, Security and Service are most important while Programmability and Community are less important than other factors in EUOS factors. Lastly, it was analysed that the influential factor of revisitation and satisfaction is Landscape, which is the common factor. Security in revisitation and Contextual links in satisfaction are especially additional factors. The landscape property is an important element to make an Entertainment Urban Open Space(EUOS). The virtue of landscape in the EUOS relates not only park facility or program that installed in the place but also the overall mood involving park user's activities in the place. To be a successful EUOS, a park facility, program and the overall mood involving user's activities need to be integrative approach to enhance the virtue of landscape.

Recent trends in urban policies show the increasing importance of urban parks. Moreover the park policy and planning are increasingly important for the good urban park system. Comparative studies in the operational system and planning contents of the parks and green space plans of the major cities would be timely and meaningful. This study aims to provide a comparative study in operational system and planning contents of the Parks and Green Space Master Plan at urban scale. Sites include London, New York, Berlin, Sydney and Seoul. Analyses are focused on the master plans and strategy reports of each city. Frameworks for analysis are divided into operational system and planning contents. The results are as follows. First, the Parks and Green Space Plans as an open space planning linked to related resources would contribute to both integrated resources management and practice of the fairness. Second, evolution from quantity to quality of the parks and green space plan enhances revitalization and regeneration. Third, shift from the 'supply oriented plan' to 'need based plan' model provides flexible planning model to meet the demographic change, trend change, preference and use. Fourth, planning agents, enlarged opportunities for participation within each phase, diversified of the participants lead the changes from the passive participation to active one. In order to improve the practicability of the parks and green space master plan, a flexible planning strategy including social awareness changes and park governance is required.

In this study, the effects of street improvement projects in particular regions are carefully scrutinized, classified, and compared based on the types of citizen participation in those projects which are offered as one of several urban regeneration methods. The Wonju and Siheung Street Improvement Projects were selected for case studies, and in-depth interviews and a survey are conducted in both regions. As a result of in-depth interviews, the Wonju project is the community initiative type in which the community has responsibilities and decision-making abilities. On the other hand, Siheung is the community participative type in which the opinions of the community have been limited The survey targeted more than 100 local merchants, and they were asked to answer to the questions which were categorized into 21 items with a 5-point Likert scale. The analysis method was carried out through a reliability test, regression. average analysis on each group, and a T-test by SPSS 18.0. Factor analysis results show four factors: physical, partnership, community, and economical revitalization. These results reveal that the social factor can be sub-divided into a community factor and partnership factor. As a result of revitalization factors by citizen participation type, the resident initiative type is more revitalized than the resident participative type in all four factors, and shows positive responses in physical and economical revitalization factors. In particular, the physical revitalization factor has a big impact on resident satisfaction regardless of type. The community revitalization factor also has an impact on two types. It reveals that the communication is as important as physical improvement. However, it shows that no type of project affects partnership revitalization. As a result of this study, if we considered only physical improvement as project achievement, you can achieve the desired outcome without consideration of residents' participation types. Furthermore, if regional revitalization is the goal of a street improvement project, we must consider other factors such as a partnership and community revitalization.
