  • The daily intake of dietary fiber by Korean population in urban and rural areas was computed from an optimized food intake based on national nutrition survey, food balance sheet, and the dietary fiber content of Korean foods. The average intake of dietary fiber the nationwide and in urban and rural areas were 24, 22 and 28g in the 1970's, 20, 21 and 20g in 1980's , and 22, 22 and 21g in the 1990's , respectively. As compared with the recommended dietary allowance of 20-25g for Koreans, the average intake of dietary fiber was within the normal range, regardless of urban and rural areas. Since the dietary pattern of korean people is being changed according to different life style, the exact intakes of dietary fiber by diverse specific population groups should be assessed in the future.

  • 국내 많은 도시들은 경제 성장률 하락에 따른 고용창출 하락, 출산률 감소에 따른 인구감소, 노령인구 증가에 따른 도시활력 감소, 도심 공동화에 따른 도시기능 쇠퇴 등 20세기에 겪어보지 못한 새로운 도시양상에 직면하고 있다. 이에 따라 이들 도시들은 도시의 당면한 문제를 해결하고 도시 경쟁력을 향상 시킬 수 있는 다양한 방안 중 하나로 창조도시에 대한 관심이 높아지고 있다. 창조도시는 주민들이 다양한 문화생활과 여가활동이 가능하고 혁신적인 산업을 진흥할 수 있는 장소가 풍부한 도시로서 과학자, 기술자, 건축가, 디자이너, 작가, 예술가, 음악가 등의 창조산업 인구에 의해 선도된다. 따라서 본 연구는 국내 도시를 인구규모별로 구분하여 어떠한 도시구조가 창조산업 인구와 관계가 있는지를 제시하는데 목적이 있다. 연구결과 광역시에서는 문화행사 수가 창조산업 인구와 관계가 있으며 대도시에서도 문화행사 수와 문화공간 수가 창조산업 인구에 영향을 미치는 것으로 나타났다. 한편 중소도시에서는 문화행사 수와 환경오염 관리시설이 창조산업 인구 유인에 영향을 미치는 것으로 나타났다. 따라서 창조산업 인구 유입에 가장 큰 영향을 미치는 요소가 도시문화임에 따라 도시 경쟁력을 강화하기 위해서는 다양한 도시문화 환경을 조성하는 것이 시급하다.

  • 본 논문의 목적은 우리나라 도시공간구조 변화를 시계열적으로 분석하고, 지역별 규모별 그 특성을 도출하는 것이다. 본 논문에서 도시공간구조는 인구밀도경사함수(population gradient curve)를 통해 분석하였고, 분석의 시간적 범위는 자료구축의 가능성을 고려하여 2000년부터 2010년까지로 설정하였으며, 공간적 범위는 광역시를 제외한 70개 도시이다. 본 논문의 분석결과를 요약하면 다음과 같다. 첫째, 우리나라 도시들은 평균적으로 도심 인구밀도는 감소하고, 인구밀도 경사도는 완만해져 도심 집중현상보다 외곽지역으로의 확산이 활발하게 진행되는 것으로 나타났다. 둘째, 비수도권 지역은 전국 평균과 동일한 형태의 공간구조 변화를 경험하였지만, 수도권 지역은 외곽지역뿐만 아니라 도심까지 인구밀도가 함께 높아지는 현상이 나타났다. 셋째, 인구 20만 이상의 중도시와 대도시에서는 도심 집중현상보다는 도시 외곽지역으로의 확산이 우세하게 나타난 반면, 인구 20만 미만의 소도시에서는 도심 인구밀도가 높아지면서 인구밀도 경사도의 절댓값이 커지는 도심 집중현상, 즉 압축도시의 특성이 나타나는 것으로 분석되었다.

  • While various fiscal measures have been used to influence regional capital inflow or industrial location, the effect of fiscal variables on labor mobility has been little understood. Understanding the relationship between the composition of local public and urban migration would enhance the city govenment's ability to pursue an appropriate population policy. In order to examine the potential for local public finance to be utilized as a policy tool in directing urban population growth, this paper analyzes the impact of local government financial structure on urban migration. In examining the data on local government finance and the changes in population of Korean cities during the last ten years, it was found that cities with high per capita expenditure in regional development have experienced high population growth rates. In this study migration equations were constructed using various fiscal variables such as the proportion of special account expenditures which are mostly spent for local development purposes, per capita regional development expenditure, degree of local financial independence and per capita net fiscal benefit, along with other explanatory variables. The results of regression analysis showed that city government's regional development expenditure variables have a positive effect on urban net migration and a negative effect on outmigration. Fiscal independence and per capita net fiscal benefit had mixed effects on in and out migration variables, implying that local tax burden does not consistently deter inmigration or induce outmigration. Based on the results of this study some important policy implications can be found regarding local government's fiscal policies. Those cities seeking to attract higher population inflow should make a greater effort in appropriating local expenditures for regional development purposes such as infrastructure, housing, and transportation. city governments should not be too concerned about high local tax burden or necessarily seek to enhance financial independence for these factors do not exert a clear influence on urban population growth or labor supply.

  • The purpose of this paper was developing a development density control model for urban growth management, using system dynamics modeling. The density control model was developed to see how urban growth, transition, and decay occur depending on the interaction among population, houses, industry structure, land and urban infrastructure such as road, water supply, and sewage treatment facilities. Suggesting adequate level of development density control using the model was another purpose of this paper. The model was applied to An'yang city to estimate the maximum number of population, industry structures, houses, and cars that can be adequately sustained with the current An'yang city's infrastructur capacity. The computer simulation results shows that the city is overpopulated by some 90,000 people. To reduce the population to the adequate level that the current urban infrastructure can sustain, the current city regulation on floor area ratio are needed to be strengthened at least 20 to 35%.

  • It is important for urban planners and policy makers to understand complex, diverse urban demands and social structure, but this is not easy due to lack of data that represents the dynamics of residents at micro-geographical level. This paper explores how to create population data at at a micro-level by allocating population data to building. It attempted to allocate population data stored in a grid layer (100 meters by 100 meters) into a building footprint layer that represents the appearance of physical buildings. For the allocation, this paper describes a systemic approach that classifies grid cells into five prototypical patterns based on the composition of residential building types in a grid cell. This approach enhances allocation accuracy by accommodating heterogeneity of urban space rather than relying on the assumption of uniform spatial homogeneity of populations within an aerial unit. Unlike the methods that disaggregate population data to the parcel, this approach is more applicable to Asian cities where large multifamily residential parcels are common. However, it should be noted that this paper does not demonstrate the validity of the allocated population since there is a lack of the actual data available to be compared with the current estimated population. In the case of water and electricity, the data is already attached to an individual address, and hence, it can be considered to the purpose of the validation for the allocation. By doing so, it will be possible to identify innovative methods that create a population distribution dataset representing the comprehensive and dynamic nature of the population at the micro geographical level.

  • Purpose: Residential differentiation is often considered to be one of the social problems that intensify urban inequality. The purpose of the study was to analyze the changes in the Gwangju urban landscape due to foreign inflows after reviewing the different frameworks about the causes of residential segregation and verifying compliance through case analysis. Method: This study analyzed the increase of Gwangju Foreign Population based on the data of the Statistics Korea and derived the concentrated areas of foreign population using GIS program. Then through the field research around the target areas, the changes of urban landscape by the foreign residents was analyzed. The foreign population in Korea recently surpassed 1.5 million is expected to increase further, and has already raised numerous social issues especially in urban area. Result: Therefore, basic and systematic analyses on foreign population and its impacts on urban residential landscape are necessary to resolve the issues. Since Gwangju is also in a similar situation, this research is first, to address the current situation and identify the problem, and then to suggest the directions for resolving them. It is also expected to be helpful provide a basic reference for related further researches.

  • This paper studies urban growth in Korean cities. First, I document that population growth patterns change over time and that the current population distribution supports random urban growth. I confirm two empirical laws-Zipf's law and Gibrat's law-both of which hold in the period of 1995-2015, but do not hold in the earlier period of 1975-1995. Second, I find a systematic employment growth pattern of Korean cities in spite of the random population growth. I examine market access effects on employment growth. Market access, a geographical advantage, has a significant influence on urban employment growth. The market access effect is higher in the Seoul metropolitan area than in the rest of the country. This effect is stronger on employment growth in the manufacturing industry compared to employment growth in the service industry. These results are robust with various checks (e.g., different definitions of urban areas). The results here suggest that policymakers should consider geographical characteristics when they make policy decisions with respect to regional development.

  • Urban greenery is an important component of urban environment and is fast gaining prominence especially in the developing countries. The destruction of urban trees has resulted to the degradation of the environment, thus the introduction of green Kumasi project by Kumasi Metropolitan Assembly, Ashanti Region of Ghana. The composition and diversity of urban trees gives rise to adequate management and monitoring, thus an inventory of urban trees of the Metropolis was conducted to document complete information on its density, diversity, composition and distribution. A total tree population of 1,101 was enumerated in the principal roads of the Metropolis. The ten most encountered tree species accounted for 61.04% of all the individual tree populations with Mangifera indica being dominant. The dominant families: Fabaceae, Moraceae and Arecaceae constitute 38.57% of the tree population. Diversity of the tree species was very high. The minimum diversity criteria were met on analysis of the diversity of this population. The proportion of exotic species was high with 65.71% of the trees belonging to the introduced species. It is recommended that greater emphasis should be placed on the planting of indigenous trees in future tree planting exercise.
