Although numerous studies have analyzed the relationship between subway travel demand (STD) and various characteristics of subway catchment area (SCA), a few studies examined the relationship between STD and the structure of pedestrian networks within each SCA. Hence, this study evaluates the structure of pedestrian networks within 79 SCAs in the city of Busan using Space syntax and investigates the relationship between STD and several characteristics of SCA including the spatial structure of pedestrian network. The analysis results show that the spatial integration of pedestrian networks within the SCAs, which represents the magnitudes of walking accessibility to subway station, is positively associated with STD among the three spatial indexes such as integration, connectivity, and intelligibility. In addition, the results show that STD significantly increases as the number of travel gathering facilities and the average floor area ratio within the SCAs increase. This study ultimately corroborates that designing the grid pedestrian network and assigning the travel gathering facilities to the compact buildings within SCAs are needed to ameliorate the spatial structure of SCA in the city of Busan as transit-oriented development system.

Approaches to spatial analysis differ from the type of spatial objects to be treated. Especially, in here, the case where two spatial data sets coexist is considered. The goal of such case lies on detecting a subset of spatial objects out of a large set that affects the distribution of the other object. However, it is not easy to extract a subset from a large set by visualization just with the help of GIS since huge amount of data are provided nowadays. In this research, therefore, relationship between two different spatial data are analyzed by quantitative measure in the case study of marketing geography. A purchase history data of a small retail store and the location of its competitors are given as source data for the analysis. The goal of analysis from the aspect of this case study is to extract strong competitors of the store that affects the sales amount of the store among many competitors. With the result, therefore, it is expected that market area pattern and competitive power of stores under micro scale retail environment would be understood by quantitative measure.

This research has the purpose to approach 'Audience participation theatre' through applying the concept of 'Hybrid' which newly come to the fore after 21st in a theatre space. In fact, 'Hybrid' has been suppling crucial power to create and pass a culture down for a long time, and it could not different to a theatre space. The hybridity in previous traditional theatre which is central 'text' and 'architectural theater' is limited movement only on the stage, such as 'an actor between presence and absence', 'a theatrical time between real and fiction' and 'an objet between An Sich(thing itself) and Fur Sich(thing with inner meaning). However after 20st's 'Avant-Garde' with 'decomposition sprit', the hybridity become broader from only on the stage to entire theatre space including auditorium caused by collapse the boundary between auditorium and stage. In other words, 'auditorium' and 'audience' are considered as 'a theatrical element' coequal with other elements, and it can create various special results through they are mixed equally. Therefore, 'Audience participation theatre' could regarded a kind of hybrid phenomenon between 'auditorium and audience' and 'actor and stage' which are most disparate relation, and it is also approached 'hybridized audience', 'hybridized space' and 'hybridized text' as a new identity.

In order to improve user accessibility and interactivity, system scalability, service speed, and a non-standard internet web environment, we developed a Web-based geovisualization system of oceanographic information using HTML5 and dynamic particles. In particular, oceanographic and meteorological data generated from a satellite remote sensing and radar measurement and a 3-dimensioanl numerical model, has the characteristics of a heterogeneous large-capacity multi-dimensional continuous spatial and temporal variability, based on geographic information. Considering those attributes, we applied dynamic particles represent the spatial and temporal variations of vector type oceanographic data. HTML5, WebGL, Canvas, D3, and Leaflet map libraries were also applied to handle various multimedia data, graphics, map services, and location-based service as well as to implement multidimensional spatial and statistical analyses such as a UV chart.

Recently, because of the need to wide-area spatial data for spatlal analysis and military purpose, there are increasing demand for the efficient retrieval of mass spatial data in Geographic Information System(GIS) fields. Oracle Spatial and ESRI ArcSDE, that are GIS Software, are to manage mass spatial data stably and to support various services but they are inefficient to retrieve mass spatial data because of the complexity of their spatial data models and spatial operations. Therefore, in this paper, we developed a spatial middleware that can retrieve mass spatial data efficiently. The spatial middleware used Oracle which is a representative commercial DBMS as a repository for the stable management of spatial data and utilized OCCI(Oracle C++ Call Interface) for the efficient access of mass spatial data in Oracle. In addition, various spatial operating methods and the Array Fetch method were used in the spatial middleware to perform efficient spatial operations and retrieval of mass spatial data in Oracle, respectively. Finally, by comparing the spatial middleware with Oracle Spatial and ESRI ArcSDE through the performance evaluation, we proved its excellent retrieval and storage performance of mass spatial data.

In keeping with the increasing demand for medical services in accordance with the economic development, the use of oriental medicine is on the rise year by year. In particular, it is a tendency that the elderly over age 65 prefer the oriental medicine to the western medicine in Korea. Under the circumstance, changing into an aging society, the importance of oriental medical services has been growing. In this regard, this study evaluated the quality of medical services by conducting the density analysis and the accessibility analysis of oriental medical clinic targeting Jinju, which is one of local small and medium-sized cities. The study results reveal that oriental medical hospitals accounted for 27% of the entire medical facilities in Jinju, and there was an imbalance in the quality of the oriental medical services according to districts(called dong) because oriental medical hospitals were mainly concentrated in the central commercial areas. In particular, in terms of the analysis on the accessibility of an aging population over age 65 to the oriental medical hospitals, over 50% of the whole districts (dongs) in Jinju were blind spots in medical services, showing a very vulnerable condition. Accordingly, it is judged that systematic measures for improvement in support of the oriental medical services in local small and medium-sized cities should be provided in Korea when we consider the characteristics of Korea where an aging population is rapidly increasing.

Objective : This study aimed to systematically examine studies on the life-space mobility in community-dwelling elderly and analyze and summarize the research trends. Methods : The Embase and PubMed databases were searched for articles on the life-space mobility of community-dwelling elderly published between January 2010 and January 2020. Based on the selection and exclusion criteria of the 335 articles, a total of 27 articles were finally selected and analyzed. Results : As a results, 11 (40.7%) cohort studies had evidence level II. This study showed that the participants in the studies were healthy elderly (81.5%), and the University of Alabama Life-Space Assessment (UAB-LSA) used the most participants (88.9%). Of the foci of the 27 finally selected studies, 8 (29.6%) were physical, 8 (29.6%) were psychosocial, 6 (22.2%) were cognitive, and 2 (7.4%) were social, and 3 (11.1%) were others. The life-space mobility of the elderly needs to be analyzed from a multidimensional point of view, and not based on a single factor such as the physical, cognitive, psychosocial, or social. Conclusion : The results of this study are expected to verify causality through the study of life-space mobility for the elderly staying in various communities and provide future directions for the study on the mobility of the elderly's and the development of community-based intervention programs.

This paper is concerned with an important aspect of regional income convergence, ${\beta}$-convergence, which refers to the negative relationship between initial income levels and income growth rates of regions over a period of time. The common research framework on ${\beta}$-convergence which is based on OLS regression models has two drawbacks. First, it ignores spatially autocorrelated residuals. Second, it does not provide any way of exploring spatial heterogeneity across regions in terms of ${\beta}$-convergence. Given that empirical studies on ${\beta}$-convergence need to be edified by spatial data analysis, this paper aims to: (1) provide a critical review of empirical studies on ${\beta}$-convergence from a spatial perspective; (2) investigate spatio-temporal income dynamics across the U.S. labor market areas for the last 30 years (1969-1999) by fitting spatial regression models and applying bivariate ESDA techniques. The major findings are as follows. First, the hypothesis of ${\beta}$-convergence was only partially evidenced, and the trend substantively varied across sub-periods. Second, a SAR model indicated that ${\beta}$-coefficient for the entire period was not significant at the 99％ confidence level, which may lead to a conclusion that there is no statistical evidence of regional income convergence in the US over the last three decades. Third, the results from bivariate ESDA techniques and a GWR model report that there was a substantive level of spatial heterogeneity in the catch-up process, and suggested possible spatial regimes. It was also observed that the sub-periods showed a substantial level of spatio-temporal heterogeneity in ${\beta}$-convergence: the catch-up scenario in a spatial sense was least pronounced during the 1980s.
