The purpose of this study is to understand the social welfare approach and to suggest implications for the establishment and expansion of social welfare techniques in recent urban regeneration to overcome the limitation of physical approach to urban regeneration. We used the method of the content analysis to extract social welfare programs in project plans of urban regeneration regions and vulnerable residence regions and then let them be categorized according to characteristic and form of their programs. As a result of the analysis, there are 4 welfare programs in urban regeneration regions; setting the economic fundament, improving the residential environment focusing on welfare, pursuing community integration and social service providing. And each type was classified into 12 subtypes. Based on the result of this study, some implications are suggested to operate social welfare techniques in a stable manner in urban regeneration projects; link of the suitable jobs for regional characteristics, the participation of local residents in the project process, empowerment for community integration and expanded provision of social services.

The purpose of the current study was to select vulnerable regions with insufficient child care services based on an in-depth investigation of diverse regional characteristics and to establish a practical goal for the expansion of public child care centers through identifying priority regions in foremost need of public child care centers out of the vulnerable regions. The vulnerable regions were selected from both urban and rural areas with particular criterions to determine their critical situation. First of all, the number of children aged zero to five, private and public child care centers, and capacity and enrolment of the regional child care center were selected from towns (Eup) and townships (Myeon) within rural areas and neighborhoods (Dong) within urban areas to calculate the capacity fulfillment. Specifically, a dense population of low-income families inhabited within urban areas defined the region's vulnerable status for the analysis, whereas poor accessibility of a child care center within rural areas correspond to the lack of child care services. The analytical result displayed that a total of 456 towns and townships did not acquire child care centers. Out of 456 towns and townships, 162 were selected as priority regions. On the other hand, 546 neighborhoods corresponding to upper 30 percentiles of urban area where children receive basic subsidy for low income families were selected as vulnerable regions. Out of 546 neighborhoods, 243 were selected as priority regions according to the analytical result.

A comparative study of the dental health perception and dental health behaviors among 12,325 middle and high school students in urban and rural areas was conducted by using "2010 National Dental Health Investigation". The results of this study are as follows. For the dental health perception and the utilization of dental service, all middle and high school students had a low perception of the their dental health status toward the farming and fishing regions from the urban. For the time of tooth-brushing among the dental health behaviors, most middle and high school students brushed their teeth after lunch. In connection with the frequency of cariogenic snack intake, high school students had a greater percentage toward the farming and fishing regions from the urban. For the dental health status, middle school students in big cities had a high average of carious permanent teeth, but high school students had a high average of carious permanent teeth toward the farming and fishing regions from the urban. In other words, there was no significant difference in missing permanent teeth, filling permanent teeth and decay permanent teeth between middle school students by region, but high school students had a greater percentage of the dental health perception and dental health behaviors toward the farming and fishing regions from the urban, showing a little difference. Consequently, there was a relationship between middle and high school students' perception of dental health and their behaviors of dental health.

With the passing of Special Act on Promotion and Support for Urban Regeneration (will be hereafter referred to as the Urban Regeneration Special Act) in December 2013, urban regeneration projects have begun in full scale. 13 regions including Jongno District, Seoul were selected as the urban regeneration leading area in 2014 and 33 regions as urban regeneration general regions in 2015 to push ahead a nationwide urban regeneration front supported by government funds. However, it is not clear if these urban regeneration projects will be revitalized by the sole means of government's financial support. Above all, cooperation among all interested parties including the central government that is propelling urban regeneration, local governments, state corporations, private entities, and citizens is urgent. In an urban regeneration project, delegation between state and private entities is absolutely crucial. The central government and the pertinent local government must provide their support by forming new policies and repairing old institutions that are right for urban regeneration, securing the necessary subsidy, and outsourcing government-owned land development. A state corporation must play its part in every aspect that requires public character such as an overall project management of an urban regeneration project, cooperation with the local government, and infrastructure installation. The private stakeholder must share his private capital and know-hows as a construction investor and a development businessman to make possible a successful urban regeneration project. In order for these public and private entities to cooperate with one another, it is necessary to reestablish the role of a public developer and contemplate running an urban regeneration project that permeates public character through a public developer.

A random sampling or systematic sampling method is commonly used to assess the accuracy of classification results. In remote sensing, with these sampling methods, much time and tedious work are required to acquire sufficient ground truth data. So, a more effective sampling method that can represent the characteristics of the population is required. In this study, fractal analysis is adopted as an index for reference sampling. The fractal dimensions of the whole study area and the sub-regions are calculated to select sub-regions that have the most similar dimensionality to that of the whole area. Then the whole area's classification accuracy is compared with those of sub-regions, and it is verified that the accuracies of selected sub-regions are similar to that of whole area. A new kind of reference sampling method using the above procedure is proposed. The results show that it is possible to reduce sampling area and sample size, while keeping the same level of accuracy as the existing methods.

The purpose of this study is to analyze the characteristics of the 11 southeastern states in the United States by using regional characteristics variables and to classify the regions. First, 19 variables from four categories of population, society, industry-economy and urban service were selected and factor analysis were conducted, and the result showed five major factors of population, economic condition, job and commuting. Based on the following factor scores, a cluster analysis was conducted, and eight types of big city, medium-sized city, bed town, small town, urban hinterland, retirement town, and rural village were derived. These types of spatial distribution characteristics showed big cities were by different types of regions and they formed metropolitan areas. Each types of classified regions were located along the road network with hierarchy. The study focused on cases in the southeastern regions of the United States and can be used as a comparison with Korean cases. If the same research method is applied to Korea in the future, or if the time series of changes is tracked by analyzing different time points, it will greatly help identify the characteristics of urban and rural mixed areas.

Spatial-temporal meteorological features of the Ulsan metropolitan region (UMR) were analyzed using observations and high-resolution numerical modeling. Long-term trend analysis (1970~2013) showed a significant increase of $0.033^{\circ}Cyr^{-1}$ in the 5-year moving average temperature, although detailed short-term features varied, whereas wind speed and relative humidity over the same period displayed clear decreases of $-0.007ms^{-1}$ and $-0.29%yr^{-1}$, respectively. These trends indicate the effects of regional climate change and urbanization in the UMR. Seasonal variations averaged for the most recent three years, 2011~2013, showed that temperatures in three different regions (urban/industrial, suburban, coastal areas) of the UMR had similar seasonality, but significant differences among them were observed for a certain season. Urban and industrial complex regions were characterized by relatively higher temperatures with large differences (max.: $3.6^{\circ}C$) from that in the coastal area in summer. For wind speed, strong values in the range from 3.3 to $3.9ms^{-1}$ occurred in the coastal areas, with large differences clearly shown between the three regions in September and October. Diurnal variations of temperature were characterized by pronounced differences during the daytime (in summer) or nighttime (in winter) between the three regions. Results from the WRF modeling performed for four months of 2012 showed large variations in gridaverage temperature and winds in the UMR, which displayed significant changes by season. Especially, a clear temperature rise in the urban center was identified in July ($0.6^{\circ}C$ higher than nearby urban areas), and overall, relatively weak winds were simulated over urban and inland suburban regions in all seasons.

Urban population growth and consequent rapid urbanization involve some thermal environmental problems in the cities. Monitoring of thermal environments in urban areas such as hot spot analysis is required for effective actions to resolve these problems. This study selected 14 dongs and surrounding administrative districts of Sejong city as study areas and analyzed the characteristics of changes in surface temperature due to the urban expansion in the summer from 2013 to 2018. In the study, the surface temperature distributions in the study areas were plotted using surface temperature values from Landsat 8 and NDVI (Normalized Difference Vegetation Index) and NDBI (Normalized Difference Built-up Index) based on KOMPSAT 2/3 data, and the patterns of surface temperature changes with urban expansion were discussed using the estimated NDVI and NDBI. In particular, the distinct urbanization in the study areas were selected for case studies, and the cause of the changes in the hot spots in the regions was analyzed using high-resolution KOMPSAT images. This study results present that hot spots appeared in urbanized regions within the study areas, and it was plotted that the lower the NDVI values and the higher the NDBI values indicate the temperature values are high. The land surface temperature and satellite-based products were used to divide the study areas into continuously urbanized regions and rapidly urbanized regions and to identify the different characteristics depending on land covers. In the regions with distinct surface temperature changes by urbanization, the analysis using high-resolution KOMPSAT images as presented in this study could provide effective information for urban planning and policy utilization in the future.

This study investigates the impacts of urban land-use fraction and temperature advection on the urban heat island intensity over the Seoul metropolitan area using the UM (Unified Model) with the MORUSES (Met Office Reading Urban Surface Exchange Scheme) during the heat wave over the region from 2 to 8, August 2016. Two simulations are performed with two different land-use type, the urban (urban simulation) and the urban surfaces replaced with grass (rural simulation), in order to calculate the urban heat island intensity defined as the 1.5-m temperature difference between the urban and the rural simulations. The land-use type for the urban simulation is obtained from Korea Ministry of Environment (2007) land-use data after it is converted into the types used in the UM. It is found that the urban heat island intensity over high urban-fraction regions in the metropolitan area is as large as 1℃ in daytime and 3.2℃ in nighttime, i.e., the effects of urban heat island is much larger for night than day. It is also found that the magnitude of urban heat island intensity increases linearly with urban land-use fraction. Spatially, the estimated the urban heat island intensities are systematically larger in the downwind regions of the metropolitan area than in the upwind area due to the effects of temperature advection. Results of this study indicate that urban surface fraction in the city area and temperature advection play a key role in determining the spatial distribution and magnitude of urban heat island intensity.

This paper investigated the characteristics of population structure and the determinants of population movement in the south west area of Kyonggi-do by grouping 9 cities in 3 categories and using Panel data of $1995{\sim}2001$. The major findings of this paper were identified as follows : 1) The population structure of regions was different to the stages of urbanization. The ratio of child and elder dependency was high in the rural regions and low in the urbanized regions. It was due to the movement of economically active population of $20{\sim}40$ aged groups, from rural regions to urban regions. This means that more productive segments of the rural population leave the country to the city. In addition. The ratio of male to female was higher in $20{\sim}40$ aged groups for rural regions. This suggested that young females moved from rural regions to urban regions more than young males in the process of industrialization. 2) Based in pooling regression, income was the most significant determinant that could explain the inter-regional and intra-regional movement of population for south west area studied, The next one was educational opportunity variable. The coefficients of income and education were 0.5, 0,7 for intra-regional migration and 0.01, 0.02 for interregional migration indicating that Todaro's hypothesis could be tested well rather than Tiebout' model for this area.
