REITs are very closely related to real estate management, but there have been no prior studies analyzing the location of REITs assets. Therefore, this study analyzed the location characteristics of REITs assets in two aspects to clarify the location characteristics by using spatial information of REITs assets. First, the characteristics of the type of city where REITs assets are distributed were analyzed, and second, the characteristics of the zoning where REITs assets are distributed were analyzed. As a result of analyzing the characteristics of the city where REITs assets are distributed by type, it was analyzed that in the case of the capital area, both the ratio of cities with REITs assets location and the intensity of REITs assets location (number of REITs assets per city) have location characteristics by city hierarchy in the order of metropolitan city > big city > small and medium-sized city. In the case of non-capital area's metropolitan and large cities, the ratio of REITs assets location cities is similar to that of the capital area, but the location intensity of REITs assets was analyzed to be significantly lower than that of the capital area. As a result of the analysis of REITs assets by type, housing REITs assets tend to be located in the old downtown commercial zoning and the new downtown residential zoning, office REITs assets are characterized by concentration of location in specific commercial zoning of Seoul, and retail REITs assets are located mainly in the old downtown station area. In addition, it was found that logistics REITs assets tend to be located in management zoning, centering on key logistics hub cities in the region.

The conservation and restoration of wetlands are essential tasks for the sustainable development of human society and the environment, providing vital benefits such as biodiversity maintenance, natural disaster mitigation, and climate change alleviation. This study aims to analyze the strategic interactions and interests among various stakeholders using game theory and to provide significant grounds for policy decisions related to wetland restoration and development. In this study, hypothetical scenarios were set up for three types of cities: large, medium, and small. Stakeholders such as governments, development companies, environmental groups, and local residents were identified. Strategic options for each stakeholder were developed, and a payoff matrix was established through discussions among wetland ecology experts. Subsequently, non-cooperative game theory was applied to analyze Nash equilibria and Pareto efficiency. In large cities, strategies of 'Wetland Conservation' and 'Eco-Friendly Development' were found beneficial for all stakeholders. In medium cities, various strategies were identified, while in small cities, 'Eco-Friendly Development' emerged as the optimal solution for all parties involved. The Pareto efficiency analysis revealed how the optimal solutions for wetland management could vary across different city types. The study highlighted the importance of wetland conservation, eco-friendly development, and wetland restoration projects for each city type. Accordingly, policymakers should establish regulations and incentives that harmonize environmental protection and urban development and consider programs that promote community participation. Understanding the roles and strategies of stakeholders and the advantages and disadvantages of each strategy is crucial for making more effective policy decisions.

The purpose of this study is to analyze the impact of attracting a university campus on the local economies of small and medium-sized cities, focusing on changes in local commercial neighborhoods(such as the number of startups, closures, and stores counts). For this study, a Difference-in-Difference(DID) analysis was used to compare the period before and after the attraction of university campuses in four local small and medium-sized cities. These include the Yangsan Campus of Pusan National University, the Jincheon Campus of Woosuk University, the Taean Campus of Hanseo University, and the Dangjin Campus of Hoseo University. The comparison was based on the number of startups, closures, and store counts, using local data provided by the Ministry of the Interior and Safety. The main findings of the study are as follows. First, attracting a university campus has a positive impact on the number of startups, both spatially and temporally. The spatial factors for the number of closures and stores showed a decrease, while the interaction terms representing the period before and after attracting the university campus all indicated an increase. Second, the number of startups in cultural and food-related sectors increase, reflecting the new demand created by attracting the university campus. However, there was also an increase in the number of closures, indicating rapidly changing consumption trends among university students. Third, physical environmental factors such as the number of building floors, land use zoning, and officially assessed land prices have a significant impact on the number of startups, closures, and stores. This supports the assertion that attracting university campus have a positive impact on the revitalization of local commercial neighborhoods.

As a part of domestic and international 'Time-Urban Planning,' the concept of 'n-minute city' is being discussed. However, relevant research in this area remains insufficient. Particularly in South Korea, studies focusing on n-minute cities based on accessibility are notably lacking. Therefore, this study aims to investigate Changwon City, dividing it into urban and non-urban areas. For each of the eight different aspects of 'Living SOC', we analyze accessibility and propose fundamental directions for creating n-minute cities in Changwon. The data are collected at a 100×100m cell level, including population and the location of SOC facilities. The road network data are also constructed, and the network analysis method of QGIS employed to measure accessibility to each facility. The results indicate that in urban areas, the average travel time to Living SOC is approximately 12 minutes. However, even within urban areas, locations on the outskirts take around 16 minutes, showing some variation compared to the city center. Non-urban areas have an average travel time of about 18 minutes, indicating poor accessibility. Additionally, there is significant variability in travel time to facilities depending on the specific cell in non-urban areas, necessitating targeted solutions. Considering the ongoing population decline in South Korea, achieving n-minute cities requires not only reconsidering customized facility supply and placement based on regional characteristics but also fundamentally restructuring urban spaces through strategies such as compact cities to optimize land use.

The central government has been promoting innovation cities since the early 2000s for the balanced development of the country in order to solve the problems of overcrowding in the metropolitan area and underdevelopment of the country due to rapid urbanization since the 1980s. The 10 innovation cities built through the regional relocation of public institutions were expected to have positive effects such as economic revitalization and population influx, but uncertainties and various externalities still exist. Therefore, this study aims to analyze innovation cities from the perspective of urban resilience to create sustainable cities. To this end, the research analyzed urban factors in the physical, natural, social, economic, and institutional dimensions of Ulsan Ujeong Innovation City, and applied the Adaptive Cycle and Panarchy to comprehensively analyze them. As a result of the analysis, it was found that the built, socio-economic, and natural environments are currently undergoing the adaptive cycle stages of preservation, reorganization, and growth, respectively, and the interaction and structural causal relationships between Korea, Ulsan Metropolitan City, and Ulsan Ujeong Innovation City were identified. The study concluded that Ulsan Ujeong Innovation City can be sustainable by utilizing opportunities such as the central government's Innovation City Season 2 and financial support, construction of Janghyeon Advanced Industrial Complex, and fostering local innovation clusters according to local conditions.

This study presents an innovative framework for comprehensively evaluating the competitiveness of maritime logistics hub cities through the development of the Global Maritime Logistics Hub Index(GMLHI) model. This model departs from traditional cargo volume-centric assessments, establishing a balanced evaluation system that encompasses various dimensions including shipping, ports, logistics, urban competitiveness, and sustainability. The Delphi survey method applied in developing the GMLHI model significantly enhanced its validity and practicality by systematically incorporating expert opinions from diverse fields. This approach enabled an objective assessment of the index composition's appropriateness and the importance of each indicator, while fostering consensus among experts to improve the model's reliability. Furthermore, the use of data from reputable international organizations such as the OECD, UNCTAD, and the World Bank strengthened the objectivity and reliability of the evaluation. This contributed to ensuring consistency in comparisons between cities and countries, while laying the groundwork for future time-series analyses. The results of this study can serve as valuable foundational data for objectively diagnosing the current competitiveness of global maritime logistics hub cities and formulating future development strategies. In particular, by enabling a multifaceted understanding of each city's strengths and weaknesses, it supports policymakers in making decisions based on more accurate situational analyses. Moreover, this research is expected to provide important evidence for developing concrete and effective policies to enhance the global competitiveness of major domestic maritime logistics hub cities. By offering useful insights in various aspects such as setting investment priorities, establishing a foundation for international cooperation, and promoting sustainable development, it can ultimately contribute to national economic development.
