response to the global city. It was developed to cope with the decline of the manufacturing industry, a rise in unemployment and a welfare state system in danger. In cities of the concept, there has been much change in existing urban space and accordingly wisdoms and knowledge has been accumulated. The purpose of this research is to scrutinize urban spatial modification of a regenerated model city "Bologna". The target area of analysis was a ex-factory ailing district. Field site visit, deep interview with professionals and citizens, walk through observation, and historial literature review on the site were employed. As results, its history, retrofit process and current change were systematically described. The results showed ways of thinking, attitude toward historic preservation, technology, and creativity of using existing buildings for contemporary functions. This has a significant implication on Korean urban development which mostly, has ignored the existing value of community and buildings.

Our society confronts a new social demand to protect the environmental equity of the people, and the green open space that is a representative public property which takes a very important role for the residents in less privileged urbane area in terms of providing amenity without requiring individual expenses additionally. This study aims to identify the current status and problems based on the environmental experiences of the actual residents, excluding the simple physical status, in relation with supplying public property of green open space, and the study put focus on the old downtown area of Jeonju-si which is a test-bed of urbane regeneration planned by the government. Residents in less privileged area evaluate the importance of green environment of park very highly as a factor to enhance their quality of life, but as they do not have well-established environmental infrastructure to back up their needs practically, they face difficulties to use such environment and show low level of satisfaction. In particular, as such characteristics appear remarkably among the least privileged urbane people in the less privileged urbane area, their dependence and expectation upon the environment of green open space is very apparent and, therefore, it is urgently needed to improve their environment for public green park area for the less privileged urbane people.

Data from an investigation of vulnerable conifer species in the subalpine zone in Korea obtained by the Korea Forest Service in 2017-2018 and monitoring research conducted by the National Institute of Forest Science since 2014 were used to analyze the status of distribution and growing condition of three major conifer species (Abies nephrolepis, Abies koreana, and Picea jezoensis) in the subalpine zone in the Baekdudaegan protected area. The distribution area of the studied species in the Baekdudaegan protected area was ca. 74% (8,035 ha) of the total distribution area in Korea, indicating that Baekdudaegan is a core area for conservation and restoration of subalpine conifer species. From decline index [A. nephrolepis in Mt. Taebaeksan and Mt. Deogyusan increased by 77.3% and 29.6%, respectively; A. koreana in Mt. Jirisan (Chunwangbong Peak) increased by 45.2% in four years; and P. jezoensis in Mt. Jirisan (Chunwangbong Peak) increased by 47.8% in two years] and seedling frequency (lower frequency of newly recruited seedlings than dead seedlings) results, the studied species are expected to face difficulties in sustainability. In contrast, at Mt. Seseoksan and Chunwangbong Peak in Mt. Jirisan, the health of trees and seedling frequency showed a partial tendency to recover and increase. In addition, we identified the relationship between the decline index and seedling frequency. These results will support the implementation of conservation strategies for vulnerable conifer species in the subalpine zone.

The diversification of the New Deal urban regeneration projects, that started in 2017 in accordance with the "Special Act on Urban Regeneration Activation and Support", generated the increased demand for the accuracy of data-driven diagnosis and project type forecast. Thus, this research was conducted to develop an application model able to identify the most appropriate New Deal project type for "eup", "myeon" and "dong" across the country. Data for application model development were collected through Statistical geographic information service(SGIS) and the 'Urban Regeneration Comprehensive Information Open System' of the Urban Regeneration Information System, and data for the analysis model was constructed through data pre-processing. Four models were derived and simulations were performed through polynomial regression analysis and multinomial logistic regression analysis for the application of the appropriate New Deal project type. I verified the applicability and validity of the four models by the comparative analysis of spatial distribution of the previously selected New Deal projects by targeting the sites located in Seoul by each model and the result showed that the DI-54 model had the highest concordance rate.

This study was performed to investigate tree injury with air pollution and acid precipitation in industrial area and rural area. This study analyzed the ion properties of pollutant precipitated in the forest of Ulsan ＆ Onsan area and correlation between S $O_2$concentration in air and the degree of forest decline. pH of industrial area was lower than that of rural area and electrical conductivity and pH had a negative correlation(r=-.7861$^{**}$). Correlation of cation and anion(especially S $O_{4}$$^{2-}$, N $O_{3}$$^{[-10]}$ ) in precipitation and S $O_2$in air was higher in industrial area. In seasonal change, winter and spring were higher. In the analysis of correlation between forest decline and variables of precipitation properties, correlation coefficient was higher by following order: S $O_{4}$$^{2-}$>pH>EC>N $O_{3}$$^{[-10]}$ >S $O_{2}$$^{2-}$>C $l^{[-10]}$ . Regression formula by computation was Y = 5.1007-0.7811 $X_2$(pH) +0.0253 $X_{5}$ (S $O_{4}$$^{2-}$) +0.0275 $X_{6}$ (N $O_{3}$$^{[-10]}$ ). In considering the result of this study, it was predicted that air pollution and acid rain would affect soil acidification and forest decline continuously.y.

The purpose of this study was to find ways to promote residents' participation as an important key for urban regeneration and enhancing urban competition. The Korea Convergence Society. The case of the design and operation of the community academy as part of the urban regeneration project (the New Ddeul Village Project) in the S district of Busan Metropolitan City was analyzed based on the strength model. Based on the job, this study presented some empirical discussions for a successful community engagement program. First, move away from the pathological model based on regional problems and approach it as a positive and potential-oriented strength model. Second, it is co-prosperity by utilizing the resources of local universities around the village. Third, to meet the diverse needs of local residents, they should seek regional support and exchanges through the convergence of college majors.

This study investigates whether urban expansion can act as a cause of the decline of the original city center through the Space Syntax methodology. The urban spatial structure analysis was conducted targeting the downtown area of Jeju-eupseong. The time points for longitudinal analysis were set at five points between 1914 and 2021 including the Japanese colonial period when the cadastral map was drawn up in Jeju City, and the urban spatial structure was analyzed and compared for each time point. ASA (Angular Segment Analysis) was used as a technique for urban spatial structure analysis. This study shows that urban expansion is a cause of the decline of the original downtown. The original city center has moved away from the center as the urban structural change due to the urban expansion. The urban structure of the eastern part of Jeju City has undergone a major transformation between 1914 and 2021. As the old Jeju area where the original city center was located is geographically in contact with the sea, urban sprawl has been made toward Halla Mountain and further to the south of Jeju. Accordingly, the city center has transformed from a monocentric to a polycentric structure. Due to the dynamics of the urban sprawl, the old downtown of Jeju became one of the peripheral neighbourhoods in the Greater Metropolitan of Jeju.

University has various resources such as intellectual human resource, spatial resource and facilities, and economic resource. At the same time, universities are, in general, found upon fundamental mission of public service, as well as teaching and research. Recently in Korea, it has been argued that we should make use of such resource of universities in the process of urban regeneration through university-community partnership. Yet, these arguments are lack of concreteness: 'which' kind of resource for 'what' kind of problem, and 'how'. Therefore, this research examined the case of university-community partnership in Japan and tried to find of some implications to Korean society. The reason for examining Japanese case is because Japan has experienced similar problems that Korea face such as aging population, decrease in the number of student, deteriorations of existing urban area; there are respectable amount of similarities between Japan and Korea in political, social and economic context; and because Japan has proceeded regeneration of communities through university-community partnerships.
