  • Along with the rapid development of the economy, the urban scale has extended rapidly, leading to the formation of different types of urban function districts (UFDs), such as central business, residential and industrial districts. Recognizing the spatial distributions of these districts is of great significance to manage the evolving role of urban planning and further help in developing reliable urban planning programs. In this paper, we propose an automatic UFD division method based on big data analysis of point of interest (POI) data. Considering that the distribution of POI data is unbalanced in a geographic space, a dichotomy-based data retrieval method was used to improve the efficiency of the data crawling process. Further, a POI spatial feature analysis method based on the mean shift algorithm is proposed, where data points with similar attributive characteristics are clustered to form the function districts. The proposed method was thoroughly tested in an actual urban case scenario and the results show its superior performance. Further, the suitability of fit to practical situations reaches 88.4%, demonstrating a reasonable UFD division result.

  • This study aims at proposing a sound and sustainable development direction of an urban commercial district by identifying space syntactic properties, from the perspective of human ecology, of the street network in Enuengjeongi culture street as the representative commercial district of Daejeon City in Korea. The results are obtained through Angular Segment Analysis (ASA) on the street network in subject area for this study. It was found that most of the socially integrated nodes are arranged along the axis of main street in the district. However, in some of those nodes, it was investigated that the social integrative function have weakened, because open spaces as public space for the general public are occupied illegally by commercial purposes of shops and car parking. It was found that the socially isolated nodes are located at the district boundary connected to a relative narrow street, with a relatively low density of the commercial facilities. Besides, it was identified that a street width in the commercial district may be a factor affecting the social integration of a space on the basis of the openness of the space.

  • Even though the existing urban residential district was obsolete and out of date in respects of physical environment, it is maintaining the function of dwelling. It ends up being regenerated as a viable urban residential district when improved the dwelling environment. Therefore, the government has been planning for the residential improvement projects for those areas applying for innovative ideas. But the government programs have often been troubled with people in the process of executing the projects or making a plan. In this respect, two parties couldn't communicate freely about the problem of those areas. So, the problematic issues of the areas should be shared with local residents at the beginning of decision making and the process of workshop participating local residents will be needed for understanding the standpoint of the residents. This study is to explore the potential of residents participating workshop to figure out current problems of the urban residential district in the process of executing the residential improvement project of Nakyang residence area in Sangju city. Upon investigation residents participating workshop is very practical in making a plan, but needs positive participation by resident and a decision making system dealing with the information shared and the understanding gained by participants.

Samples were drawn from the various sources of a district in seoul. 53 persons involved in district health's administration(the Members of a District Parliament, the senior officials of a District office, village chief) and 84 health center workers were surveyed with anonymous postal questionaires and 427 district private medical personnels with postal questionaires and 625 users of a health center with direct questionaires, from November 18 to 25, 1996. Additionally, 12,151 households were surveyed with self-reported questionaires including priorities on special district health services of health center, from September 1 to 7, 1996. The major findings were as follows : 1) Although the persons involved in district health administration tend to put lower priority on health service over other community activities, they well acknowledged the importance of health center. But health center workers strongly acknowledged the importance of both health service and heath center. 2) As to the level of human resoureces, equipments and ammenities of Health Center commpared with private medical institute, the persons involved in district health's administration and health center workers responded that health center was higher in following order : 54.9%, 41.6%, 36.5% and 88.0%, 80.7%, 44.1%. 3) Concerning the priorities of health center's improvement, the persons involved in district health's administration replied in the order of reinforcement of proffesional health workers (43.3%), improvement of equipments and ammenities(28.3%), and the health center workers replied in the order of reconstruction of organization(24.1%), public health education and promotion(22.8%), reinforcement of proffesional health workers(21.0%). 4) Both the persons involved in district health's administration and health center workers replied that Ministry Health and Welfare, District office, health center were essential as the most critical organizations in the activation of Health Center's Function. 5) Persons involved in district health's administration and health center workers chose, as the most important health center's Function, medical treatment and prevention of infectious disease, and prevention of acute and chrone disease control and special district health service, respectively. Both Groups replied that fammily planning and parasite control are no longer in need. 6) As the future health service requiring reinforcement, every human resources parties considered health conselling, health line, sex education as the most imortant elements in public health education. Concerning the reinforement of other health services such as medical checkup and visiting nurses, every human resources parties showed more than 80% approval rate, but for oriental medical care service, the private medical personels showed relatively low approval rate(52.9%). Therefore the planning for reinforcement of health center's function requires the reflection of human resources party's opinion and the implication of system which can control and combine the differences in party's opinions.

  • A mathematical model is developed in order to describe the network configuration and heating distribution to a Central District Heating System for an Urban Residential Community. The purpose of using this model is to optimize operating costs and to distribute heat to the Residential Community efficiently. In particular, because of the inherent nonlinearity and dual optimization of the problem a dyamic programming approach is taken. It is turned out that the optimal cost of the system is a strong non-linear function of the network. In particular, it is found that increasing N, the number of houses, may not necessarily imply increased costs. It is felt that past failure of producing economical systems may be due to the improper attention given to the network.

  • Purpose: We would like to identify the appropriate size of stores in the commercial district suitable for the era of low growth. In addition, it is intended to present alternatives to prevent gentrification along with measures to revitalize commercial districts according to the selection of appropriate stores. Research design, data and methodology: The importance and commercial district usage patterns were identified through surveys by consumers and sellers. the demand and size of the commercial area were calculated based on the floating population and resident registration population. In addition, based on this, through metric analysis, the importance of the business district activation plan and what important matters can prevent gentrification were analyzed. Result: In this the study, 555 stores are currently operating in the target area, but it is seen as a commercial district with a scale that can operate 136 stores and 938 stores. In addition, it was analyzed that the Commercial Lease Protection Act needs to be strengthened to prevent gentrification. Conclusions: Due to the nature of small and medium-sized cities in Korea, commercial districts that have once lost their resilience must take much effort to find vitality. It is believed that local commercial districts will have resilience when diagnosis and recovery measures are adequately presented.
