The purpose of this study is to present implications using local government data, focusing on the occurrence of empty houses, one of the serious social problems emerging due to population extinction and aging. The subjects of the study were Mokpo-si, which has the highest percentage of empty houses in the country, and the spatial distribution status was identified by schematizing the status of empty houses by grade on a map through data from the local government's survey on empty houses. As a result of the survey on vacant houses, it was confirmed that 90% of empty houses in Mokpo City were included in the project district of the urban regeneration strategy plan underway in Mokpo City. Currently, the empty house maintenance project is difficult to proceed smoothly due to difficulties in purchasing empty houses and lack of budget for local governments, so in order for the project to proceed quickly, it is necessary to come up with a plan to promote the project in connection with the urban regeneration strategy plan in Mokpo.

The new paradigm of urban regeneration, would promote the comprehensive communal view. Therefore, the community role has become an important and necessary for regeneration of communities. It is necessary for urban regeneration which should be matched with the regional characteristics, to develop an evaluation framework that can objectively and accurately diagnose the status of community; so it can be an integrated prescription. A new alternative, asset-based approach may be an alternative to build the community based on opportunities and strengths, which focuses on community inside and things that community have. In this study, a community asset is defined as the tangible and intangible components in the community. A community asset evaluation system is developed through the content analysis related to previous studies of several researchers who investigated the asset-based approaches. Community assets are classified into seven types: human, social, cultural, natural, physical, economic, and political property. Each type is classified into components and establish as a framework with 3 levels in order to set the indicators which can be measured concretely.

The average life span is over 80 years of age, and various biomaterials have being studied. Many research institutes and companies around the world have been commercializing bioactive glass through R&D, however, there is not much research in Korea. Most bioactive glass is applied to bone regeneration in powder form due to its excellent bio-compatibility. Recently, new applications such as scaffolds for tissue engineering and nerve regeneration have been found in composite form. The global market size is not as large as US $ 556 million in 2019, but the growth rate is very high at a CAGR of 14.35 %. This field is waiting for the challenge of new researchers.

In order to achieve an efficient urban regeneration of the nation, it is required to determine the extent of decline nation-wide and the declined areas for each district and also to evaluate the potentials of the concerned areas. For this task to be accomplished, a construction of a comprehensive diagnostic system based on spatial information considering diversity and complexity is required. In this study, a total information system architecture for urban regeneration is designed as part of the construction of such a diagnostic system. In order to develop the system, a city and district level unit decline diagnostic indicators has been constructed and a decline diagnostic system has been developed. Also, a scheme to promote the advancement of the system is proposed. The DB construction is based on the city and district level nation-wide and metadata for the concerned level is constructed as well. The system is based on the Open API and designed to be flexible for extension. Also, an RIA-based intuitive UI has been implemented. Main features of the system consist of the management of the indicators, diagnostic analysis (city and district level decline diagnosis), related information, etc. As for methods for the advancement, an information model in consideration of the spation relations of the urban regeneration DB has been designed and application methods of semantic webs. Also, for improvement methods for district unit analytical model, district level analysis models, GIS based spatial analysis platforms and linked utiliation of KOPSS analysis modules are suggested. A use of a total information system for urban regeneration is anticipated to facilitate concerned policy making through the identification of the status of city declines to identify and the understanding of the demands for regeneration.

As Urban Regeneration is being carried out, stakeholders are most likely to have disagreements on their interests. Besides, dispersion of numerous communication routes and obscure decision processes aggravate the situation. Eventually, fragmented decision-making processes and complex structure lead to inefficient outcome and delay of projects. This paper is a study on decision-making support not only helps the program manager have more efficient and optimum decision, but also provides alternatives for Urban Regeneration. This study is conducted as follows. Firstly, the project process and the decision-making structure among stakeholders in Urban Regeneration are analyzed, and then the current status of decision-making in Urban Regeneration project is classified. Secondly, with literature study on "Gateway Review", the decision-making gateway review process in Urban Regeneration is defined, and then the "Gateway Review Elements" are listed. Thirdly, to establish gateway review process, this paper presents a check points, namely gate which supports a program manager to monitor and to control the program management in Urban Regeneration. Each gate has several supporting tools such as diagram of critical decision points relation, scheme of stakeholder, checklist. Fourthly, the proposed concept is verified by experts who have been carefully selected to provide their respective reviews. Finally, decision-making support gateway review system is modified based on their critiques and suggestions.

Today, there is increasing recognition of the importance of urban regeneration for better public places. Urban parks as a public area play an important role in harnessing its positive impact on people's well-being: where the standards and funding of/for the parks are getting worse. There is however less a focus on policy approach to park regeneration in the country. Neverthless, a few UK's cases of such innovative park management(PM) has shown successful park regeneration based on policy support. Therefore, the aim of this research is to draw policy implications by exploring a case of successful park regeneration. To address the aim, this research conducts an in-depth case study of 'Manor Fields Park, UK', digging into its PM structure and PM body 'Green Estate Ltd' in relation to relevant policy. The data is mainly collected by interviews including a group interview. The analytical framework 'Place-keeping(PK)' and its six dimensions are employed to determine the characteristics of MFP's PM structure. Resultingly, there is a significant shift in the approach to PM which stresses the principle of long-term and self-sustaining structure led by a non-profit organisation and strong impacts of policy. In this context, PK highlights significant drivers for parks regeneration particularly in terms of policy implications: 1)providing policy support to encourage non-profit organisations in PM, 2)extending community involvement in decision-making processes, 3)promoting income generation by community groups, 4)shifting public awareness of shared responsibility for PM, 5)completing regular park maintenance assessment by community groups, and 6)delivering low-maintenance approaches to PM. To support these implications, PM structure for successful parks regeneration does meet a holistic and multi-dimensional approach of place-keeping underlined by understanding policy contexts and rethinking current status quo of PM. Addressing these implications will shed light on urban PM in an era of austerity and ultimately contribute to improving people's well-being.

This paper examines port redevelopment and urban regeneration projects of foreign advanced countries and investigates policy implications to apply to Korean port cities. Busan and Incheon have started to redevelop old port facilities located near old city centers and they have been faced several problems. Significant findings are found from the experiences of Inner Harbor in Baltimore, Darling Harbor in Sydney, Hafencity in Hamburg, Eastern Dockland in Amsterdam and Minatomirai 21 in Yokohama etc. At first, port and city have to be integrated to an unique regeneration project in order to solve the spatially disconnected problems originated from separate development in the initial stage. Preservation of historical regional assets is highly recommended to characterize its own value which is emphasized in the age of post modernism. Accurate and consistent design guidelines of port cities are stressed to build high standard cities. In the perspective of investigating a new business model, anchor facilities and place marketing strategies are introduced to induce more people to the place specially in the beginning stage. In addition, creative financing methods and competent implementing bodies are emphasized to running the projects stably regardless of real estate market status.

Purpose: The purpose of this study was to analyze the cumulative survival rate of dental implants installed with guided bone regeneration (GBR), and also elucidate the factors related with the survival of dental implants. Material and Methods: This retrospective study was conducted on 148 dental implants installed in 76 patients by one specialist (Y.K.) at the Department of Periodontology and Implant Center, Seoul National University Dental Hospital from 2001 to 2010. The cumulative survival rates were obtained by the Kaplan-Meier method. The correlations between various factors and dental implant survival were analyzed by using the log-rank test and Cox proportional hazards model. Results: Among 148 dental implants installed in 76 patients, 8 implants in 7 patients were lost and the cumulative survival rates up to 5-years and 10-years were 97% and 89%, respectively. Gender, smoking status and location of implant were significantly associated with the cumulative survival rate of implants (p < 0.05). Age, history of hypertension and diabetes were not significantly associated with the cumulative survival rate of implants (p > 0.05). Conclusion: The dental implants installed with guided bone regeneration is predictable technique according to the results of cumulative survival rate over 10 years.
