In areas such as trade area analysis and urban planning, the maturity assessment of central places is important information to be taken into account for rational decision-making. In this study, 3 business areas, typical retail businesses (retail, personal service, food and beverage), are extracted from year 2004 and 2009 phone books, and centrality index and location quotients for 3 business areas are calculated. Using these outputs growth, declination, and maturation of central places are figured out, then comparing and analyzing these results assessment method for central places is proposed. As a result, it is known that the maturity of central place, such as growing, declining, and maturing, can be assessed by comparing the location quotients of 3 retail business areas. In growing central place, location quotient of food and beverage business is much higher than others, and in maturing central place, that of retail business is much higher than others. Assessment results of central places are very useful, as an important index, to determine branch opening or select business area, in trade area analysis.

As can be seen in US case with the introduction of ISTEA and CAAA, the expansion of the transportation decision-making role of local government is expected to be quite apparent in Korea, and the increased importance of decision-making in transportation issues requires increased attention to both justification and analysis of transportation initiatives. A GIS-based facility management system in a desktop computing environment has been constructed using MapInfo, ARC/INFO, and Microstation to allow such expanded role of local government's decision-making activities. In this paper, first, authors try to explain the procedures of system design; that is, the digital map production including vectorizing, data conversion, attribute data entry, and application programming development. Then, various management functions which are basically embedded in MapInfo environment, and application functions established by the use of MapBasic language has been explored Finally, the possible benefits of combining geographic information systems with traffic planning scheme has also been described with some discussion.

Reliability of the estimation is usually damaged in the situation where a linear regression model without spatial dependencies is employed to the spatial data analysis. In this study, we considered the conditional autoregressive model in order to construct spatial association structures and estimate the parameters via the Bayesian approaches. Finally, we compared the performances of the models with spatial effects and the ones without spatial effects. We analyzed the yearly total crime count data measured from each of 25 districts in Seoul, South Korea in 2007.

Vehicles transporting hazardous materials can make huge damage to people, properties and environment by traffic accidents. Therefore, transporting hazardous materials is a big issue with the cutting edge technology of communications in these days. However, despite this situation, Korean government gives limited efforts for systematic management, research and investment about hazardous materials. Accordingly, this research suggests the key path finding algorithm about management of real-time schedule and routes for vehicles transporting hazardous materials. Besides, the case study is progressed in transportation networks of Seoul in order to evaluate the reality of algorithm. Specifically, time-space network transformation is performed for time window attributes. In addition, this study proposes the techniques searching for non-dominated paths considering schedule by the multiobjective shortest path algorithm based on dynamic programming in dynamic transportation networks including multiobjective attributes.

Korean Film Council (KOFIC) is entrusted by the Ministry of Culture, Sports and Tourism, Republic of Korea, aiming to support and promote Korean films. With the government's policy for balanced regional development, KOFIC head office will be relocated to Busan. Busan is famous for the Busan International film Festival and their effort for Korean film industry. Until now, the Korean film industry is concentrated on the Seoul metropolitan areas. With the relocation of KOFIC, it is the time for KOFIC to recognize and promote and Busan as the Second key Cluster of Korean film industry. With the cooperation with Busan Film Commission, KOFIC needs to set up the new promotion plan for Korean film industry for future including building new film production studio, raising regional film production fund, and scouting new talented filmmakers.

The study addressed a direction that environmental facilities along avenues will make a progress via urban environment as well as location marketing. The space is specified the campus avenue, which is located in Jongro-gu at Seoul. With the emergence of digital information era, both people' life style and behaviors have been changing in many different ways. As the first approach to the direction, the historical study of the avenue is examined by focusing on the change. All possible related status such as location marketing strategy and various spatial characteristics, environment of the avenue and its facilities are investigated and users' characteristics are analyzed. Through these processes, a new direction and role of design are proposed and are believed to improve the avenue' image and to rediscover its own identity and to make the avenue alive as it used to be. The new proposed direction showed how to approach to design as well as to system of environmental facilities along avenues and in addition to highlighting continuous and synthetic plan. Furthermore, It is expected that both the efforts to improve the avenue' image based on its own cultural characteristic and to foster the cultural-commercialized facilities will contribute to the local residents' life standard and its economic status.

The closure of education office is due to a decrease in the number of students, but it is necessary to look at various causes of this decrease. In particular, unlike other regions, Gyeonggi Province has a large number of students due to redevelopment, relocation of businesses, and changes in school districts. In addition, it is necessary to set the overall direction for the use of closed schools and seek ways to establish an efficient operation and management system in preparation for the changing future of the educational environment. Through this study, the closure of schools in Gyeonggi-do is different from that of local schools. The measures to utilize closed schools in Gyeonggi-do Province should be different and contribute to realizing the utilization of closed schools.

Although various efforts to increase the usage of the Yeouido Saetgang river have been made after it was established as the first ecological park in 1997, its usage is significantly lower compared to neighboring Yeouido Han river park. In this study, an interview survey of 1,000 visitors to Yeouido Saetgang river park was conducted. The perception and activity patterns among the visitors were examined. The results showed that about 60 percent of all users were neighboring residents who can move by a walk. Most of the visitors spend their time in the river park taking exercises and observing the ecosystem. It is similar to the characteristics of other city parks in Seoul. The perceptions and activity patterns according to the visitor's characteristics were analyzed statistically. Also, the effect level of activity patterns on the perceptions such as satisfaction, attachment, and willingness to participate was analyzed and discussed.

This study analyzed the physical characteristics and change characteristics of urban detached residential area. In the reality of South Korea in which the history of modern urbanization is not long, the densification that progressed together with sudden population growth without any consideration of city plans became to reveal many problems. Thereafter, apartment-centered large scaled development plans have been implemented until now as an alternative for the foregoing. As the residential environments of old downtown areas that were excluded from the development have been gradually deteriorated, large scaled re-development and reconstruction projects have been adopted as ways to solve the problems of the old downtown areas. On one hand, the development methods that damage the history of the detached housing areas have been resisted. With such a background, this study attempted the analysis of the change characteristics of the Kookmin Housing Complex in Suyu 1-dong, Seoul with a view to playing the role of evidentiary materials for the disappearing urban detached housing areas or those urban detached housing areas that may be revived. This author hopes and the results of this study will lead to careful development that presents measures to maintain and develop modern urban residential areas where the history of past residential areas and culture are disappearing due to full-scale redevelopment.

Urban land cover classification is role in urban planning and management. So, it's important to improve classification accuracy on urban location. In this paper, machine learning model, Support Vector Machine (SVM) and Artificial Neural Network (ANN) are proposed for urban land cover classification based on high resolution satellite imagery (KOMPSAT-3A). Satellite image was trained based on 25 m rectangle grid to create training data, and training models used for classifying test area. During the validation process, we presented confusion matrix for each result with 250 Ground Truth Points (GTP). Of the four SVM kernels and the two activation functions ANN, the SVM Polynomial kernel model had the highest accuracy of 86%. In the process of comparing the SVM and ANN using GTP, the SVM model was more effective than the ANN model for KOMPSAT-3A classification. Among the four classes (building, road, vegetation, and bare-soil), building class showed the lowest classification accuracy due to the shadow caused by the high rise building.
