  • The objective of this research is to compare and analyze regional accessibility of Korean primary school students to oral health services from the perspective of public health geography by using geographic information system in which the choropleth map has been regarded as the most popular method. Statistical proximity on the basis of calculus of 205 regions-based school oral health data is optimized to set five class intervals for five maps. These choropleth maps of oral heal programs such as oral health education, tooth-brushing method education, preventive dental care and curative dental care, demonstrate that there exist wide regional discrepancies throughout the country in terms of primary school students' accessibility to oral health services within the programs. The paper not just contributes to overcoming the existing paradigm by actively considering an interdisciplinary research among public health dentistry, dental hygiene and geography of public health, but provides clear evidence for national oral health policy in South Korea.

  • The objective of this research is to analyze geographical distribution of Korean dental hygienists to provide the geographical basis of supply-side policy for dental hygienists from the perspective of dental geography by using Geographic Information System (GIS) in which the choropleth map has been regarded as the most popular method. The present report is highly meaningful for the policy of dental hygienist on the supply side of dental care market. The data used in the article derive from the statistics-associated portal site provided by Korean government. It includes the statistics on general population, the regional numbers of dental hygiene students, county-based numbers of registered dental hygienists, dentists, and dental clinics and hospitals. Several maps are created by investigating these statistical data with GIS. This study is focused on the comparative analysis between entrants to the department of dental hygiene, registered acting dental hygienists and dentists in terms of county-based distribution per its population. The main result demonstrates that whereas about half of dental hygienists and dentists are respectively concentrated in Seoul and Gyung-gi, just one-fifth of entrants to the department of dental hygiene in the Seoul-metropolitan area. From the perspective of the supply-side policy of dental hygienists, the research argues that the creation or expansion of the department of dental hygiene does not directly meet social need for dental care services.

  • This research concerns with the urbanization in Pusan City, the largest port city of Korea focus on the changes of traffic volume from 1970 to 1994. These results are as follow: (1) Urbanization of Pusan City has progressed with increasing the efficiencies of streets. At the first, it's ribbon developed along the main artery toward inland. Urbanization is the process of bear a resemblance to characteristics of CBD. It has both expansion and diffusion processed, simultaneously. Urbanization has progressed centered certain nuclei and developed with more varieties are ally and temporally. (2) Traffic volumes according to times which go and return to piers affected to the traffic pattern of the some parts within the city, it is one of characteristics in port city. Variation of traffic volumes according to times much greater at the nearer streets the piers and connected street with it than the rest of the areas within the city. Rivers and mountains affecting to the traffic pattern and play roles of diffusion barriers for urbanization. (3) In the mid-1980, regions which locate along the main arteries had reached to as same level of urbanization as central part of the city. And higher ranked central places within Pusan City developed toward pattern of CBD in the past. It suggests that these central places revoluted to the recreation of CBD function in the past. (4) Urbanization has developed as same as cell differentiation in process, and it encouraged the more greater variation among the regions and become clear the hierarchy of central places within the city.
