Climate changes may cause substantial changes in spatial patterns and distribution of vector-borne diseases (VBD's), which will result in a significant threat to humans and emerge as an important public health problem that the international society needs to solve. As global warming becomes widespread and the Korean peninsula characterizes subtropical climate, the potentials of climate-driven disease outbreaks and spread rapidly increase with changes in land use, population distributions, and ecological environments. Vector-borne diseases are typically infected by insects such as mosquitoes and ticks, and infected hosts and vectors increased dramatically as the habitat ranges of the VBD agents have been expanded for the past 20 years. Medical geography integrates and processes a wide range of public health data and indicators at both local and regional levels, and ultimately helps researchers identify spatiotemporal mechanism of the diseases determining interactions and relationships between spatial and non-spatial data. Spatial epidemiology is a new and emerging area of medical geography integrating geospatial sciences, environmental sciences, and epidemiology to further uncover human health-environment relationships. An introduction of GIS-based disease monitoring system to the public health surveillance system is among the important future research agenda that medical geography can significantly contribute to. Particularly, real-time monitoring methods, early-warning systems, and spatial forecasting of VBD factors will be key research fields to understand the dynamics of VBD's.

This paper aims to investigate changes in the characteristics of urban spatial structure in Korea by regional groups and city size between 2000 and 2010. The characteristics of urban spatial structure is analyzed by Clark's population gradient curve in this paper. Therefore key parameters in population gradient function, such as population density gradients and population density in CBD represent the characteristics of urban spatial structure. The result shows that most of cities in Korea have experienced suburbanization rather than concentration, but small-size cities have experienced concentration during the period.

The purpose of this study was to compare and analyze characteristics of Gangwon Innovation City and Wonju Company Town. Both were created with similar purpose, place, time, and scale. However, they were created with different approaches: relocating public institutions and attracting private institutions. For research data, population microdata provided by the National Statistical Office were used. As a result of the analysis, the Gangwon Innovation City and the Wonju Company Town greatly influenced the population growth of Wonju and the movement of the population within Wonju. The influx of population into the study area brought positive changes in both demographic structure and population indices. Excluding relocation to Wonju-si, Innovation Cities and Company Town accounted for more than 50% of those who migrated from the metropolitan area (Seoul, Gyeonggi and Incheon). The supply of apartment houses (apartments) in the Innovation City and the Company Town stimulated the transfer from the inside of Wonju to this area. For households that moved to Gangwon Innovation City and Wonju Company Town, the most common reasons for moving in were housing, occupation, and family.

Since 1960s the rural population of Korea has continually decreased as a result of the rapid rural-to-urban migration and this caused an economic recession as well as the accelerated aging phenomenon in the rural communities. Such problems got worse in smaller rural villages and marginal villages began to appear among the rural communities. This study aims to analyze the structures and characteristics of rural marginal villages. A case study on the county of Goheung, Jeollanamdo, is carried out using survey and stakeholder interviews. With the survey results a series of comparative analysis are done revealing the commonalities and peculiarities between two different types of marginal villages. This study also tries to reveal the residents's perceptions on the marginal villages and the potential determinants of rural rehabilitation.

This paper estimates theoretically optimal sizes of urban population for major metropolitan areas using an urban economy system with utility maximizing household, profit maximizing producer and government providing public goods. This finds that the optimal size of urban population is determined by technological levels and public services. The population sizes of Seoul, Busan, Daegu and Incheon are higher than their optimal levels, while Gwangju, Daejeon and Ulsan need to increase the population for production efficiency.

This research aims to analyse rural change by increasing in urban-to-rural migrants in rural Jeju. In particular, the author analysed changes in rural area focusing on non-agricultural sector and local organization. Urban-to-rural migrants into rural Jeju have been causing increase in tourism business. Such an increase in tourism business caused increase in construction of service space and changes in land use. Meanwhile, the local organization formed by urban-to-rural migrants has differences in its members and its activities and implementing system of activities in comparison with those of native local organizations. The Seowgipo Rural Migrants Cooperative, which is the research target, has characters of urbanism even thoug it was formed in rural area.

The purpose of the study is to propose and evaluate Exploratory Spatial Data Analysis(ESDA) methods for examining age-specific population migration characteristics. First, population migration pyramid which is a pyramid-shaped graph designed with in-migration, out-migration, and net migration by age (or age group), was developed as a tool exploring age-specific migration propensities and structures. Second, various spatial statistics techniques based on local indicators of spatial association(LISA) such as Local Moran''s $I_i$, Getis-Ord ${G_i}^*$, and AMOEBA were suggested as ways to detect spatial dusters of age-specific net migration rate. These ESDA techniques were applied to age-specific population migration of Daegu Metropolitan City. Application results demonstrated that suggested ESDA methods can effectively detect new information and patterns such as contribution of age-specific migration propensities to population changes in a given region, relationship among different age groups, hot and cold spot of age-specific net migration rate, and similarity between age-specific spatial clusters.

To grasp the migration characteristics in the Busan Metropolitan Area (BMA), this study analyzed household characteristics and migration selectivity. The major findings of the study are as follows: first, young (especially 25 to 34 years of age) and single person households have greater propensity to migrate out from BMA, and their home ownership rate is low. These trends are much stronger in households that migrate out towards the Seoul Metropolitan Area from Busan. Second, age and educational selectivity of migration is evident. The characteristics of movers are quite different from those of stayers at Busan. Young people are more likely to migrate out of Busan, and higher levels of education are deeply associated with higher mobility. Through analyzing four high schools in Busan, it is acknowledged that most honor students entered 4-year universities in Seoul. The outflow of highly educated young people may induce the brain drain. Busan is undergoing both population decline and the problems caused by the brain drain.

In this study, we presented a method for estimating the potential population damage of the Seoul Nowon-gu area in the event of a terrorist using a vehicle improvised explosive devices (IED). Using the object-based building extraction method with orthophoto image, the area of the apartment has been determined, and the apartment's height and level were estimated based on the elevation data. Using the population estimation method based on total floor area of building, each apartment resident population was estimated, and then potential population damage at the time of terrorist attacks was estimated around the subway station through a scenario analysis. Terrorism damage using IED depends on the type of vehicle greatly because of the amount loadable explosives. Therefore, potential population damage was calculated based on the type of vehicle. In the results, the maximum potential damage population during terrorist attacks has been estimated to occur around Madeul station, Nowon-gu. The method used in this study can be used various population estimation research and disaster damage estimation.

Since the mid-1980s there has been an intensive debate on a regional geography in abroad, and its renaissance has been widely expressed. Under the influences of these academic circumstances, many Korean scholars have tried to introduce this trend and at the same time to propose new development lines of the Korean geography with a critical perspective. However, the empirical study of Korean regional geography including area studies is characterized by a quantitative deficit on the one hand and by its peripheral position on the other. The main reasons of this marginalization of Korean regional geography that we can find include a undifferentiated import of new systematic/nomothetic geography in the 1960s and 1970s, a historical interruption with a tradition of old Korean geography, and the practical difficulties of regional geographical approach itself. Now we face with the fundamental changes including globalization/regionalization and an increasing actual demand for the information on different scales of space and place. In order to cope with these challenges, we inevitably need to revitalize various forms and modem characteristics of regional geographical approaches and try to reexamine the basic concepts, methods, and frameworks of regional geography.
