    Abstract PDF
    Since 2016, Korean governments agencies including the Ministry of Agriculture, Food and Rural Affairs, the Ministry of Environment, and Korea Meteorological Administration have operated drought warning systems in coordination with the Ministry of the Interior and Safety. Despite multi-ministerial efforts, the ministries designate and announce various drought stages by using their individual views and methods so that municipalities and citizens are largely confused when they try to understand the severity of current and future droughts. This study suggests a novel method for integrating drought stages from three ministries into a single stage at each municipality level. The method follows three steps in order to determine the integrated drought warning stage. First, municipalities are classified into three types on legal grounds, which are intended to differentiate municipalities’ vulnerability to drought. Second, expert interviews and the analytical hierarchy process (AHP) method are used to quantify the weights of three drought stages for each type of municipality. Third, three drought stage records and estimated weights are applied to determine the integrated drought warning stage for municipalities across the country. The case with the drought in June 2022 shows that proposed methods can describe drought severity in terms of a single yardstick which is useful to communicate with the general public and local government officials, reflecting regional vulnerability characteristics in a simplified manner.

    A Typology of Korean Cities Using the Balanced Development Index: A Latent Profile Analysis Approach

    Minju Lee , Kim, Euijune | 2022, 114() | pp.17~36 | number of Cited : 0
    Abstract PDF
    This study aims to categorize Korean cities using the Balanced Development Index of the Presidential Committee for Balanced National Development and explore each group's regional characteristics. To do this, we employed Latent Profile Analysis (LPA) to classify 226 cities (local governments) in Korea. The regions were classified into five groups; (A) metropolitan cities, (B) mixed type, (C) small cities in provinces, (D) capital regions, and (E) rural areas. Based on the classification results, we identified the characteristics of regional conditions and the strengths and weaknesses of the five groups. This study calls for regional customized policy development that considers regional environments in more detail. Furthermore, it is expected to be used as material for regional development policy.

    Abstract PDF
    As the population declines and local disappearance deepens, there has been significant domestic interest in Japan's site appropriateness plan to realize a compressed city. However, there is no practical study to apply it in Korea. In this study, two key criteria for setting up a guide zone, a key element of Japan's site remediation plan, namely, the type of reference facility and the radius from the facility, were applied to the ‘myeon’ leveled cities located in Angye-myeon, Gyeongsangbuk-do, with facilities and the appropriate radius suitable for Korean conditions. Methodologically, a spatial suitability index (SCI) was devised to determine to what extent the area created with a certain radius from the reference facility corresponds spatially to the actual urbanized area, and a geographic information system (GIS) was used to determine the type of standard facility suitable for the domestic situation. The radial range was comparatively analyzed. As a result of the analysis, the reference facility combination that can best represent the current cities was 'Senior Center + Town Hall', and the influence range of the reference facility was found to be 200m. Based on these results, it is expected that there will be detailed discussions on the implementation method of compressed cities in the future.

    The Association Between SOC and Land Prices Considering Spatial Heterogeneity Based on Finite Mixture Modeling

    Kang woo seok , Kim Eunchan , Heo Wookjae | 2022, 114() | pp.53~78 | number of Cited : 0
    Abstract PDF
    An understanding of how Social Overhead Capital (SOC) is associated with the land value of the local community is important for effective urban planning. However, even within a district, there are multiple sections used for different purposes; the term for this is spatial heterogeneity. The spatial heterogeneity issue has to be considered when attempting to comprehend land prices. If there is spatial heterogeneity within a district, land prices can be managed by adopting the spatial clustering method. In this study, spatial attributes including SOC, socio-demographic features, and spatial information in a specific district are analyzed with Finite Mixture Modeling (FMM) in order to find (a) the optimal number of clusters and (b) the association among SOCs, socio-demographic features, and land prices. FMM is a tool used to find clusters and the attributes’ coefficients simultaneously. Using the FMM method, the results show that four clusters exist in one district and the four clusters have different associations among SOCs, demographic features, and land prices. Policymakers and managerial administration need to look for information to make policy about land prices. The current study finds the consideration of closeness to SOC to be a significant factor on land prices and suggests the potential policy direction related to SOC.

    Development of a Motorway Mobility Index Based on Road Network Coverage of Vehicle Trajectory

    Kwon, Cheol-woo , Chang, Hyun-ho | 2022, 114() | pp.79~90 | number of Cited : 0
    Abstract PDF
    Due to the limitations of available data, the performance evaluation of national main roadways is conducted using macroscopic traffic variables (e.g., traffic volume, travel time) that consist of the cross-sectional data of network vehicle trips. To conquer this ongoing hindrance, the aim of this research is to devise a novel mobility performance evaluation index based on the concept of spatial trip coverage. Trip length distribution, a sort of derivative data extracted from big data on vehicle GPS trajectoriesy, is employed in order for the encapsulation of spatial trip coverage. To demonstrate the feasibility of the developed index, performance evaluation of national motorway sections was carried out using the index. The analysis results were similar to what transportation experts deduce. This indirectly indicates that the index, in itself, has strong explanatory and obvious discriminating power in evaluating the mobility of any road section as a member of the road network. In addition, it was demonstrated that the index could be successfully employed for the analyses of functional road classification and weekend leisure trip of motorway sections. Therefore, it is at least expected that the proposed mobility index could be efficaciously used as a policy decision-making index in the planning and operation of national highway network.

    Centralized Managements of Government Property and Active Private Sector Participation: A Case Study in the UK’s Transitional Systems

    Kim Go-Eun , Jeong Minki | 2022, 114() | pp.91~110 | number of Cited : 0
    Abstract PDF
    This research aims to draw up effective management strategies to address the South Korean government’s problematic inefficiency in a binary system for managing government properties and to promote private sector participation, thereby exploring the political-economic change in the UK’s management systems of government properties. With a new weave of Keynesian fiscal policy in the 1950s and 1960s, the UK government launched a national drive in which the Property Services Agency (PSA) managed, maintained and furnished the fragmented government properties located across the UK. The Thatcher government had privatized public services and split up the PSA, but the Government Property Agency (GPA), newly organized by the Cabinet Office in 2018, has taken back responsibility for centralized management, which was derived from its constitutional reforms that had been carried out since the privatization period. Thus, this non-departmental agency has strengthened centralized management by imposing not only controls over internal powers, but also external cooperation with the government departments backing private sector participation. At the same time, the GPA’s Government Hubs Programme has played a key role in linking government properties scattered across the UK and enhancing cooperation among the departments. By improving South Korea’s centralized management system that can be performed by an administrative body with inter-departmental governance and commercial expertise, this research suggests not only the fundamental need for centralized management which is facilitated by a specialized agency, but also communication and cooperation with the departments for carrying out government hub projects.

    A Study on Regional Forecasting Framework Using Machine Learning According to the Changes in Commercial Property Behaviors with ICT Growth

    Choi, Jin do , Chang Yohan , I TaLy | 2022, 114() | pp.111~135 | number of Cited : 0
    Abstract PDF
    Advanced information and communication technology (ICT) stimulates several changes in our lives, including social economics and living environments. Especially in urban areas, those changes stretch to commercial properties such as the emerging needs of e-commerce and spending behaviors of customers. Now, our commercial properties face several big movements which may affect our ecosystems in social economics in several ways. This study aims to explore how such ecosystems operate in diverse fashions and to present how our ecosystems would be changed in the near future with jurisdictional level. This study found several significant clues that the future demands of commercial properties may differ and vary across jurisdictions with changes in urban spatial. To be specific, our results found that the demand forecasting of the facility groups for the first- and second-category will have negative trends across Gangwon-si, Choong-chung-do, and Jeju-si in the near future. Also, sales facilities show positive trends in the central business district (CBD) area and similar trends can be found for office facilities in Daejeon-si, Sejong-si, and Ulsan-si. This study expects that the developed framework in this study can play a meaningful role as a policy decision supporting tool since estimated demands in commercial properties can prove useful in urban planning, such as in identifying the appropriate supply that meets certain demands.
