The accumulation of spatial information - people, building, land and businesses- is required to make a rational decision successfully by utilizing the Spatial Decision Support Systems (SDSS). Many foreign countries have utilized the SDSS by defining the minimum unit of spatial area and implementing the spatial database based on it. Even though in Korea, National Basic Districts were created for the purpose of utilizing these districts as a basic area, they have not been utilized as a basic area of managing the spatial database due to the lack of attributes data. Therefore, the goal of this research is to suggest the strategies of building Spatial Decision Support Systems through the accumulation of the spatial data based on National Basic Districts. We propose the strategies in three different fields - legal system, database and application, services. We expect that the role of National Basic Districts w ill be strengthened by executing our strategies as a minimum spatial unit of Korea.

This study aims to identify limitations and pending problems after reviewing the overall policies and status of rural Newtown projects, and to seek solutions to its problems. This study targeted the villages of 5 districts, which were developed as rural new-towns after 2009 and included the basic status and progress of the pilot districts. This study conducted a literature review to examine the basic status and progress of the pilot districts, and based on this, analyzed the demand prediction, site selection, project implementation, and housing and amenity facilities of the pilot districts. The study methods included literature reviews, on-site surveys, interviews with village representatives, and consultations with experts. According to the analysis results, a low occupancy rate of the Newtown project districts is because the prediction of occupancy demand was incorrectly completed before implementing the projects. Also, the eligibility for occupancy, such as age restriction and mandatory farming was too strict. Other problems included an absence of income generation support policies for rural returnees, a housing supply policy in disregard of agricultural characteristics, and a lack of understanding of maintenance of communal space, etc.

We examine 554 state basic districts and 1832 householders in Busan metropolitan city to see whether the physical and walkable characteristics of housing influence apartment housing prices. We use two-level models modeling for a more accurate analysis. Walkable characteristics in level 2 state basic districts potentially explain 77% of the variation in housing values, with the highest impact on crime safety characteristics. Overall, our spatial multi-level analysis based on new state basic districts in Korea explained price variation better than previous studies, which considered each householder. The results provide policy opportunities for planners and citizen groups to pursue strategies that encourage the development of walkable and sustainable neighborhoods.

This study aims to establish basic data for efficient management of rural water by analyzing regional irrigation facilities and benefitted areas in the statistical yearbook of land and water development for agriculture at the watershed level. For 511 domestic rural water use areas, water storage facilities (reservoirs, pumping & drainage stations, intake weirs, infiltration galleries, and tube wells) are spatially distributed, and the benefitted areas provided at the city/county level are divided by water use area to provide agricultural water supply facilities. The characteristics of rural water district areas such as benefitted area, were analyzed by basin. The average area of Korea's 511 rural water districts is 19,638 ha. The average benefitted area by rural water district is 1,270 ha, with the Geum River basin at 2,220 ha and the Yeongsan River basin at 1,868 ha, which is larger than the overall average. The Han River basin at 807 ha, the Nakdong River basin at 1,121 ha, and the Seomjing River basin at 938 ha are smaller than the overall average. The results of this basic analysis are expected to be used to set the direction of various supply and demand management projects that take into account the rational and scientific use and distribution of rural water and the characteristics of water use areas by presenting a quantitative definition of Korea's agricultural water districts.

Under the guise of a residential environment improvement, distendedly designated Pre-Housing Renewal districts and Renewal Districts by Basic Plan for Renewal Projects are not promoted and leaved for a long-term so that residential problems have become worse. In case of the canceled Housing Renewal district, at the time when the district are canceled, the residential environment has become already superannuated for more than 10 years but there is no follow-up plan to manage that problem so that the exact management plan for those neglected districts is urgently needed. Therefore, the purpose of this study is to analyze the aspect of change of residential environment after the cancellation and indicate appearing problems by conducting on the case of Canceled districts of Daegu Housing Renewal District. This study will be the first step to seek practical management measures for canceled districts, and on the basis of this, the research will become a precedent to seek the sustainable planning measures for the designation and management of Renewal Projects from now on.

As the economy of Korea has developed, dietary patterns have also changed in many ways. Rural areas, in particular, demonstrate relatively lower food accessibility than in urban areas. The aim of this study was to examine whether or not there were differences in food accessibility between urban and rural areas using data of the Census on Basic Characteristics of Establishments, Consumer Behavior Survey for Food, of the Korean National Health and Nutrition Examination Survey. Also investigated was how such differences would affect the frequency of food purchase, dietary intake, and nutrition intake by district. The results showed that districts with the lowest 10% in food accessibility had lower frequency of food purchase than did the highest 10% districts. In terms of nutrition intake, the daily average nutrition intake was not significantly different among districts. Yet, analysis of the amount of weekly dietary intake indicated that food oasis districts had from 1.3 to 3 times greater dietary intake than did food desert districts. These findings mean that the difference in food accessibility causes unbalanced food intake. Thus, the government must take a comprehensive approach to ensure that rural residents get greater food accessibility.

The purpose of this study develops the methodology to extract the poor deprived districts using the data from the national spatial data infrastructure portal. Particularly this study tries to select more acute indicators and to test the operability of such indicators. Also this study is focused on the versatile methodology that can be adjusted to incorporate alternative indicators that might be appropriate according to the hierarchy of the spatial unit. The indicator sets are composed of three dimensions: the poor class, the poor old housing, and poor residential neighborhood environment. Each representative indicator is selected based on the characteristics of the poor deprived districts. As a result, at the level of administrative Dong, key indicators for extracting the poor deprived districts are number of recipients of national basic living security per thousand persons and ratio of households living at old detached house. At the level of the national based zip code district, the ratio of buildings built on parcels located at roads below 4m in width, the ratio of small parcels below $60m^2$ and the ratio of poor old buildings are very important indicators. The result of grid analysis by overlaying the coverage of multiple indicators shows that relatively more vulnerable and deprived districts can be extracted at the small sub-district level. This study suggests the possibility to create the high value-added information, using the data from the national spatial data infrastructure portal. This methodology enables policymakers to select the priority target districts of poor deprived district more effectively.

The national parks of South Korea take up an area of 6,726 ㎢, which accounts for 6.7% of the national land. They are national conservation areas with their area made up of 59.1% of land (3,972.6 ㎢) and 40.9% of seawaters (2,753.7 ㎢). And in 2019, the national parks are classified by type into 17 mountainous, 4 maritime or coastal, and 1 historical site. Here, the maritime or coastal nation parks are lately spotlighted as landmarks in maritime tourism. However, the area of the maritime or coastal national parks is continuously dwindling due to conflicts between the residents in the parks and Korea national park service, the continued pressure with respect to the regional tourism development and private investments, and the abolition of parks in relation to allegedly breached private properties. This study identifies the issues with the operation and management of national parks as caused by the abolition of parks and the reduction of areas, and goes from there to do research with the aim of suggesting an institutionalized improvement plan with a view to more useful operation and management of the maritime or coastal national parks. As a result, the natural resources in the sea and on land should be surveyed again to establish the standard for use-specific zoning and reorganize the park areas in adjusting the national park areas. Second, the use-specific districts need to be reviewed for their reorganization that meets the designation requirements by focusing on the characteristics of the different national parks with a view to ensuring reasonable natural conservation in the maritime or coastal national parks. Third, various support facilities for residents such as public path, lodgings, and rentals need to be created to reduce the conflicts between Korea national park service and those who live in the parks.

The objectives of the study were to provide the basic informations needed in the development of balanced medical services throughout the nation. As the national health care system was expanding rapidly along with the economic growth, quantitative re-evaluation of the system is of great need. For that reason, characteristics of the admitted patients were analyzed for the case-mix and patients' flow within and through regions. Materials were 421,530 cases of inpatients, who were reported through Korea Medical Insurance Corporation(KMIC) for insurance claim, during the period of March 1, 1985 through February 28, 1987. Korean Diagnosis Related Groups(K-DRGs) classification system was adopted for the study of case-mix and 189 cities and counties were classified into 5 district groups by factor analysis results of K-DRGS. The major findings of this study were as follows ; 1) Factor analysis of case-mix, employing K-DRG system, revealed 5 distinct funtional district groups. Group A(18 districts) was prominent for tertiary medical care. In group B(36 districts), rather simple procedures were prevalent. Group C(26 districts) was distinctive for the medical care of well organized internal medicine practices with qualified clinical laboratories. Group D(17 districts) was characterized by relatively high balanced medical care. Group E (92 districts) was with very low level of medical care. 2) Analysis of the case-flow through the districts showed 3 types of flow patterns : inflow, outflow, and balanced types. Inflow type of case-flow was found in Group A, C and D while Group B and E showed outflow type. Inflow was most prominent in Group A and Group E was of typical outflow type. Group B was consistently the outflow type except for Major Diagnostic Category XX regardless of the disease treaters, but Group C and D were inflow or outflow types according to the disease tracers.

Due to COVID-19, the external activities of urban residents have greatly shrunk, causing a lot of damage to the commercial district, such as a decrease in population and sales. The downturn in commercial districts means the collapse of the infrastructure of the national economy, and can have serious side effects on the local economy and individual lives. Therefore, it is necessary to look at the alley commercial area, which is closely related to the national local economy, and pay attention to the damage and stagnation of the alley commercial area where small business owners are concentrated. The purpose of this study is to classify alley commercial districts into growth commercial districts and decline commercial districts by using commercial sales time series data and DTW time series group analysis for the pre- and post-COVID-19 period. The main findings of the study are as follows. First, using the time series data on commercial sales before and after COVID-19, the alley commercial districts were divided into growth commercial districts and decline commercial districts, and it was confirmed that the distribution of growth commercial districts and decline commercial districts was regionally different. Therefore, it is necessary to actively manage commercial districts in areas where many declining commercial districts are distributed, and it is required to prepare policies for each region in consideration of the spatial distribution of declining commercial districts. Second, during the COVID-19 period, face-to-face essential industries, density of guest facilities, and population density negatively affected the sustainability of commercial districts, which is the opposite of previous studies. This is the result of empirically confirming the specificity of the COVID-19 period and the negative effects of the integrated economy, and can be used as basic data for effective commercial district management and policy preparation in the event of a national disaster in the future. Third, the characteristics of the background of the commercial district had a significant effect on the sustainability of the commercial district, and the negative effect of the attracting facilities inducing population concentration in the background area was found. This suggests that it is necessary to consider the characteristics of the background as well as the inside of the commercial district when establishing policies to revitalize the commercial district and support small business owners in a national disaster situation.
