This study was conducted to review data utilization plans and suggest solutions based on the need for tools that can objectively diagnose problems in rural areas. The study extracted items through prior research and was carried out as a process of reviewing data capable of constructing spatial data. The results performed in the above manner are as follows. First, prior research and expert surveys were conducted to select diagnostic items to derive details of a total of three items that should be considered for rural space plans such as regional revitalization and regeneration using regional characteristics such as environment, society, and culture. Second, as a result of listing data available for regional diagnosis, 6 types of environment, 15 types of society, and 18 types of culture were selected out of a total of 529. Finally, it was suggested to establish a national standard spatial unit by grasping the limitations of public data such as omission of spatial data and accuracy. This study is significant in that it presented implications for data utilization as well as selection of items for rural diagnosis and reviewed data utilization based on rural specialized districts of "The Act on Support for Restructuring and Regeneration of Rural Spaces" to be implemented in 2024. This is considered to be valuable as a study for sustainable rural diagnosis if processes such as spatial data construction and weight setting are carried out in the future.

The purposes of the study were to try configuring categorization of floor plans of elderly centers located in apartment complexes and to find out the spatial transfigurations regarding floor plan types. The data for the analysis of the study were collected from 56 elderly centers of apartment complexes in Ulsan by observations and interviews from July 3 through 13, 2012. The results are as follows. Firstly, the floor plans of the elderly centers were categorized into six types, which were 2R+L+K, 2R+LK, 1R+L+K/1R+LK, 1RL+K, 1RLK, and 2R+K/1R+K(no living room). Secondly, there were no salient differences among the plan types for the characteristics of physical environment of the centers. The types of 2R+L+K were relatively big in size and two thirds of the centers had gender-segregated rooms. Lastly, spatial transfigurations was found in sixty-percent of the centers, which included change of spatial arrangement, functional change, and functional addition. Interestingly, the more the spaces were segregated, the more the spatial transfigurations were performed in the way for the integration of functions of the rooms.

Spatial data streams from sensors are useful in context-awareness for many types of applications. However, an important gap is found between spatial data stream management in real-time and complex computation for spatial context-awareness, and this brings about serious difficulty to integrate spatial data stream processing and context-awareness. In this paper, we present a system called SCONSTREAM(Spatial CONtext STREAm Management) that we have developed to resolve the gap between spatial data stream and context-awareness. The key approach of our system is to filter off unnecessary spatial data streams and convert them to the spatial context streams, which are smaller and more suitable to be processed by the context-awareness module than raw data from sensors. By experimentation, We show that SCONSTREAM resolves the functional gap between spatial stream processing and spatial context-awareness module.

This study aims to derive basic living service facility items in rural areas and construct related spatial data. To do this, a literature review on the laws and systems related to the residential environment and services in rural areas, rural spatial planning, and the 'Rural Convention' strategic plan reports for the Jeolla and Gyeongsang Region in 2021 was conducted. Primary data collection and review on the list of basic living service items in rural areas derived from the analysis were conducted. After data collection, 12 sectors and 44 types of rural basic living service items were derived; the data selection was carried out based on the clarity of the subject of data management, whether it was established nationwide, whether it was disclosed and provided, whether it was periodically updated, and whether it was an underlying law. Afterwards, data on the derived rural basic living service items were constructed. Afterwards, spatial data on the derived rural basic living service items were constructed. Because open data provided through various institutions were employed, data structure unification such as data attribute values and code names was needed, and abnormal data such as address errors and omissions were refined. After that, the data provided in text form was converted into spatial data through geocoding, and through comparative review of the distribution status of the converted data and the provided address, spatial data related to rural basic living services were finally constructed for about 540,000 cases. Finally, implications for data construction for diagnosing rural living areas were derived through the data collection and construction process. The derived implications include data unification, data update system establishment, the establishment of attribute values necessary for rural living area diagnosis and spatial planning, data establishment plan for facilities that provide various services, rural living area analysis method, and diagnostic index development. This study is meaningful in that it laid the foundation for data-based rural area diagnosis and rural planning, by selecting the basic rural living service items, and constructing spatial data on the selected items.

The purpose of this study is to investigate the possibilities of architectural planning and expression of the relationship between structure and skin in contemporary architecture. For this purpose, we show interior space images -integration of structure and skin architecture- to students and experts of the related majors, and let them mark their feeling on the questionnaire composed spatial expression vocabulary extracted through the literature study on spatial sensibility, and analysis data. As a result, in contemporary architecture where the structure and the skin are integrated, form elements have a stronger influence on formation of space sense than elements of light and size, and aesthetics, characteristic, and temporality are common in the inner space, Three types of four types showed unique characteristics, and it was confirmed that there is a causal relationship between the spatial feeling factor and the spatial feeling. This means that the relationship between the structure and the skin can be considered as a planning factor, and this study is expected to be used as such basic data.

The purpose of this study is to use urban regeneration management types through classification and step-setting of physical types by administrative dong as the basis data for future urban management plans in local small and medium cities. The analysis was conducted on the physical density of each administrative dong by setting the data on urban and architecture provided by the government as three elements: buildings, lots, roads, etc. Through the system classified in this study, Mokpo City's 23 administrative districts were divided into nine management types and three management steps. Methodology can be utilized to establish areas of similar areas within the city and to use them as basic data for planning management. It is meaningful that it is possible to extract areas that need actual regeneration and maintenance through physical density analysis and plan suitable projects.

The roles of public libraries have been diverse not only provision of information but also provision of cultural programs. According to this trend, the spatial composition of public libraries have been also changed to reflect the diverse roles. This study is conducted to explore the spatial characteristics in public libraries with two objectives: 1) to suggest spatial types in public libraries based on their physical characteristics, and 2) to explore the relationships between the spatial types and users' perception. To accomplish these objectives, we adopted observation and questionnaire survey as research methods. Consequently, three spatial types of public libraries are identified based on an investigation of several public libraries: divided, partially integrated, and integrated. Then, several statistical analyses, including one-way analysis of variance (ANOVA), are conducted with the questionnaire survey data. The results from the statical analyses show that there are significant differences in users' perceptions and behaviors between the spatial types. That is, the spatial type influences user's perceptions. This study is meaningful in terms of its first attempt to explore the relationships between spatial factors in libraries and users' perceptions. Based on this, it is suggested that libraries should consider their spatial structures for developing user's positive perception on the libraries.

Purpose - This study aims to not only investigate spatial pattern of immigrants' residence and crime occurrences in South Korea, but shed light on how geographic distribution of immigrants and immigrant segregation affect crime rates. Research design, data, and methodology - Th unit of analysis is Si-Gun-Gu municipal level entities of South Korea. The crime data was obtained by Korea National Police Agency and two major types(violence and property) of crime were measured. Most demographic, social, and economic variables were derived from Korean Census Data in 2015. In order to examine spatial patterns of immigrants' distribution and crime rates in South Korea, the present study utilized GIS mapping technique and Exploratory Spatial Data Analysis(ESDA) tools. The causal linkage was investigated by a series of regression models using STATA. Results - Spatial inequality between urban metropolitan vs rural areas was visualized by mapping. Assuming large Moran's I value, spatial autocorrelation appeared to be quite strong. Several neighborhood characteristics such as residential stability and economic prosperity were found to be important factors leading to crime rate change. Residential distribution and segregation for immigrants were negatively significant in the regression models. Conclusions - Unlike the traditional arguments of social disorganization theory, immigrant segregation appeared to reduce violent crime rate and the high proportion of immigrants also turned out to be a crime prevention factor.

Purpose - Intra-industry trade of agricultural products can eliminate the disadvantage of Korea's traditional agriculture and improve its lack of comparative advantage. The main purpose of this paper is to measure the level and index of intra-industry trade of Korean agricultural products and to explore the spatial dependence and spillover effect associated with this type of trade. The main factors influencing intra-agricultural trade are analyzed from two perspectives: the population and the classification of agricultural products. Design/methodology - First, the level of intra-industry trade of Korean agricultural products is measured. Second, to obtain a more accurate estimate of the influence of various factors, and based on two types of weight matrices, a spatial econometric model is constructed from two aspects: population and classification of agricultural products. The status and the factors influencing intra-industry trade are also studied. Findings - It is concluded that there is a positive spatial correlation between Korea's intra-industry trade in agricultural products and that of its trading partners. The spatial spillover effect of this type of trade is verified by using the spatial autoregressive model (SAR). Labor-intensive agricultural products are found to have a positive spillover effect on intra-industry trade, while land-intensive products do not have a significant effect. Originality/value - In this paper, the two types of agricultural products are meticulously distinguished, and the spatial effect of the intra-industry trade of agricultural products as well as the influence of various factors are analyzed. In addition, the accuracy of the estimation of the coefficients of the factors by using the spatial econometric model is higher than that of the ordinary panel data model.

Although spatial databases support an efficient spatial management on objects in the real world, they have a characteristic that process only spatial information valid at current time, So in case of change in the spatial domain, it is very hard to support an efficient historical management for time-varying spatial information because they delete an old value and then replace with new value that is valid at current time. To solve these problems, there are rapidly increasing of interest for spatiotemporal databases, which serve historical functions for spatial information as well as spatial management functions for an object. However most of them presented in an abstract time-varying spatial phenomenon, but have not presented a concrete policy in spatiotemporal databases. In this paper, we propose a spatiotemporal data model that supports bitemporal time concepts in three dimensional architecture. In the proposed model, not only data types and their operation for object of spatiotemporal databases have been classified, but also mathematical expressions using formal semantics for them have been given. Then, the data structures and their operations based on relational database model as well as object-oriented database model are presented.
