It is increasingly important to estimate daytime population for the sake of urban administration and urban economy. The estimation of daytime population using a census data on commute, however, has its own limits, particularly when applying to the metropolis such as Seoul which is dominated by the service industry. This study suggests a pedestrian flow as another estimate of daytime population and presents a methodology of Seoul Pedestrian Flow Survey. The data of pedestrian flow gives us a view into hourly and spatial distribution of daytime population, which cannot be provided by the use of census data. In addition, comparing with a census-based daytime population on the borough level show some features of a pedestrian flow as another estimate of daytime population.

This study was conducted to remove the urban heat island effects embedded in the interpolated surfaces of daily minimum temperature in the Korean Peninsula. Fifty six standard weather stations are usually used to generate the gridded temperature surface in South Korea. Since most of the weather stations are located in heavily populated and urbanized areas, the observed minimum temperature data are contaminated with the so-called urban heat island effect. Without an appropriate correction, temperature estimates over rural area or forests might deviate significantly from the actual values. We simulated the spatial pattern of population distribution within any single population reporting district (city or country) by allocating the reported population to the "urban" pixels of a land cover map with a 30 by 30 m spacing. By using this "digital population model" (DPM), we can simulate the horizontal diffusion of urban effect, which is not possible with the spatially discontinuous nature of the population statistics fer each city or county. The temperature estimation error from the existing interpolation scheme, which considers both the distance and the altitude effects, was regressed to the DPMs smoothed at 5 different scales, i.e., the radial extent of 0.5, 1.5, 2.5, 3.5 and 5.0 km. Optimum regression models were used in conjunction with the distance-altitude interpolation to predict monthly normals of daily minimum temperature in South Korea far 1971-2000 period. Cross validation showed around 50% reduction in terms of RMSE and MAE over all months compared with those by the conventional method.conventional method.

The floating population that is index to figure out dynamic activities in urban area will be important in urban railway planning, but it is not useful because it is collected by posterior method. This study aims to investigate factors influencing floating population. The floating population data that was collected in Seoul for a month in December 2013 is used as dependent variable, and the negative binomial regression analysis is used in modelling. The number of households, number of employees, number of subway stations, and number of bus lines variables are statistically significant in predicting floating population.

In this study, a simple regression model is proposed in order to analyse the effect of population and urban land use on the water quality of Paldang lake, Gyeonggi. As a comparison result with Qua12E water quality model, the proposed model shows very good predicting performance in simulating several alternative scenarios. In order to accomplish BOD 1ppm of Paldang lake, various model applications show that the population incoming and urban land use management should be afoot in addition to stricter outflow water quality from sewer treatmement systems.

Poverty directly affects health and well-being, The poor population has a higher rate of chronics illness. higher infant morbidity and motality rates. shorter life expectancy. more complex health problems. and greater physical limitations resulting from chronic disease. In order to activate primary health care for the poverty in urban area the following measures should be taken : 1. Health center must be expended or establish subhealth center. 2. Health center must monitor neighbour's workplace's health management for their working population. 3. Health centers must do active home visiting nursing care for the urban-poor. 4. Health center must carry out flexible problem-centered practice according to the area. 5. For the urban-poor's health care must have organization of the health center & practice according to community's characteristics. 6. Public health care must be closely connected with welfare. 7. For the health care of the urban-poor must demand active community participation. 8. Health center is closely connected with Community hospital. 9. Active management of public health resource system is demanded.

Social and population geography in Korea has been developed somewhat later than other special subjects of geography. But in recent years, it has attracted much interests of geographers, and accumulated a considerably large amount of research products. Seen in this context, it is resonable to expect that social and population geography will not only lead the development of geography in the future, but also contribute to the resolution of socio-spatial problems in Korea. From this point of view, we shall retrospect in this paper the progress of social and population geography in Korea since the 1950s, and look out its future prospect and further research tasks. In the first place, we discuss general concepts and major themes of social and population geography, and overview its development process, and than review in more details some important research products which would be categorized into five main subjects, that is, research methodology, urbanization and urban population phenomena, population movement and changing rural life, residential differentiation and urban redevelopment, and urban social life and regional social well-being. Finally, we consider briefly the future prospect and further tasks of social and population geography in Korea.

This study investigates urbanization effect in warming trend of surface air temperature over Korea. The data used in this study consist of the daily minimum and maximum temperatures during the period of 32 years(1968-1999) from 16 stations of KMA. To calculate magnitude and trend of urbanization effect, stations were classified into urban and rural stations using population statistics. Urban stations were defined as those with population densities greater than 1000 persons per kilometer squared in 1995. The others were defined as rural stations. The urban stations were also subdivided into two groups according to their population totals. For estimates of urban effect magnitude, temperature change was calculated by comparing 16-year mean values between 1968-83 and 1984-99. Then, the difference between each urban station and every rural station was calculated. During the analysis period of 32 years, maximum temperature increase is $1.22^{\circ}C$. In the total temperature increase, urban effect is estimated by 28.7%. For minimum temperature, it becomes larger by about 10% than that in maximum temperature. Therefore, urban effect in an increasing trend of minimum temperature is 38.9% in the change of $1.13^{\circ}C$.

With the establishment of municipalities, public interest in small towns in Korea has been on the rise. To initiate an effective study and suggest subsequent policies for small towns, it is necessary to analyze and discuss substantive issues based on specific conditions of these small towns. The primary objective of this paper is to categorize small towns into types and to analyze the peculiarities and differences of their internal factors. The focus of this research is to determine the general characteristics of the classified towns and to suggest specific revitalization and specialized studies about them. In the main analysis of this paper, 39 small towns are divided into sets according to urban rank, conditions of location, and size of the population in the central site. Furthermore, distinctions of the divided towns are analyzed using three constituents for urban organization, including populations, activities, and facilities/land. From the research results, it was determined that there is a difference between small town types, according to population, land cost, and urban activities, based upon the urban rank and size of the population in the central site. Therefore, this paper concludes it is necessary to conduct further studies on time series analysis regarding the peculiarity changes of the types, and to complement the variables for future related studies.

Purpose: In korea, Aging in Place is underway as an alternative to elderly housing for the aging population. Currently, research is being actively conducted mainly for the baby boomer generation and older generation. There is not much research on various ages that will be needed continuously in elderly housing and aging in place in the future. Therefore, this study suggests aging in place of urban elderly housing through analysis of urban preference of all ages. Method: An analysis of prior studies related to elderly housing, Field interpretation about Aging in Place, An analysis of the city preference through the survey of the elderly, Existing Literature Survey, Housing Survey, Future Population Projection, Survey of the elderly and confirmed the necessity of the Aging in Place of urban elderly housing. Result: As there are many generations living in the city and many people prefer it, studies on urban elderly housing should be actively conducted and should be studied as Aging in Place that can be used for all ages. In addition, it is necessary to study the advantages and disadvantages of using Aging in Place in the city through domestic or overseas case analysis.

To understand the relationship between road-traffic noise and urban components such as population, building, road-traffic and land-use, the city of Cheongju that already has road-traffic noise maps of daytime and nighttime was selected for this study. The whole area of the city is divided into square cells of a uniform size and for each cell, the urban components are estimated. A spatial representative noise level for each cell is determined by averaging out population-weighted facade noise levels for noise exposure population within the cell during nighttime. The relationship between the representative noise level and the urban components is statistically modeled at the cell level. Specially, we introduce a spatial auto regressive model and a spatial error model that turns out to explain above 85 % of the noise level. These findings and modeling methods can be used as a preliminary tool for environmental planning and urban design in modern cities in consideration of noise exposure.
