New urbanization different from the manufacturing based urban growth has been widely discussed in post-modern city, consumption city and others to reflect the urban changes in qualitative manner. Urbanization stage models consider large cities to be in mature stage, reurbanization and the stages are assumed to be experienced successively in lower sized cities. However, since the industrial restructuring implies new urbanization experiences, this study examines new urbanization in diverse aspects such as the population change and the geographic and social characteristics of commuters and migrants for the 6 large cities in Korea. Seoul follows the urbanization stages in order while other 5 large cities are divergent in their transition from the industrial city. Regional large cities reveal broad reverse commuting and selective in-migration of economically active households for better work and housing opportunities available in central cities. Similar to the consumption city thesis with enhanced cultural and recreational amenities in western cities, the widening urban residential function including housing and other services is a new urbanization characteristic of large cities in Korea.

산업의 발전과 급속한 대도시화는 환경오염이라는 새로운 사회적 이슈를 발생시켰다. 시정(Visual Range)이란 대기의 혼탁도를 나타내는 기상요소로서, 정상적인 시각을 가진 사람이 목표를 식별할 수 있는 최대거리를 의미한다 시정은 대기오염을 판단할 수 있는 척도이며, 항만 및 공항 등에서는 인명 및 재산과 직접적인 관계를 갖고 있어, 최근 시정 측정에 대한 중요성이 높아지고 있다. 본 논문에서는 배경 잡음에 좋은 특성을 가지며, 보디- 정확한 시정 측정을 위하여 905nm 펄스 모드 반도체 레이저 다이오드를 이용한 시정계 센서를 제작하여 실험하였다.

최근 들어 우리의 활동영역이 실외에서 실내로 점차 이동됨에 따라 실내공간의 공기 오염은 중요한 관심사가 되고 있다 실내공기오염은 주로 학교, 사무실, 공공건물, 지하공간 등에서 발생하는 것으로 조사되고 있으며, 그 위해성이 심각한 정도는 아니지만 하루 24시간 중 80% 이상을 실내에서 생활하는 사람들의 건강에 해를 미치는 것은 분명한 것으로 인식되고 있다(NRC, 1981； 김윤신, 1995). 이러한 실내공기 오염현상은 전세계적으로 빌딩 등이 밀집되어 있는 대도시에서 자주 보고되고 있으며, 국내의 경우도 1970년대 이후 대도시화와 에너지 소비가 급증함에 따라 실내공기 오염의 우려가 높아지고 있으나, 실외 대기오염에 비해 다소 소홀히 인식되고 있다.

Colombia experiences a population growth in their metropolitan areas through an accelerated urbanization process, a housing deficit and a shortage of urban developable land. To solve these problems, the central government developed a national policy for a large-scale housing city development including supra-municipalities planning instruments such as Macroprojects. However, the amount of housing land supplied by this policy is insufficient and additional policies for shortage housing and qualitative deficit are required, particularly in regions with a high concentration of population. The purpose of the study is to compare urban development systems of Colombia and Korea and explore the possibility of applying guidelines to Colombia through i) comparing the capital region cities of the two countries with an asymmetry context method, ii) comparing both urban planning system founding similarities and differences, and iii) suggesting new urban development challenges in the Bogotá metropolitan area based on Korea's new town experience.

우리나라는 1960년대부터 시작된 산업화와 도시화의 결과 대도시, 공업단지의 대기오염이 매우 심각한 상황으로 최근 들어 대기질 개선을 위하여 유해 물질에 대한 배출을 엄격히 규제하고 있다. Beer-Lambert 법칙에 근거하여 측정 대상 물질에 의한 빛의 흡수가 파장에 따라 달라지는 것을 응용한 DOAS 측정 방식을 통한 대기오염의 측정은 선진국에서 이미 1970년대 후반에 연구, 개발되어 왔으나, 우리나라에서는 DOAS 부분의 연구가 매두 미진한 실정이다.(중략)

Difficulties in riding , driving and parking are a common issue which inevitably appears in city urbanization and city modernization development all over the world. However, those cities differ in controlling the traffic. According to the specific practice in Shanghai, this article presents the various factors which affect the traffic capacity and operation quality . This article also outlines transportation system management technique of overall coordination and comprehensive control in the following seven aspects : controlling traffic motivation : improving traffic distribution : reasonably and scientifically selecting travel mode, travel route and travel time : reinforcing traffic management and road construction. The article finally suggests that the above mentioned points are cost-effective ways of the handling traffic plight for metropolitan transport.

This paper is to analyze citizens' consciousness on urban changes during the 1900s in the sectors of economy, politics and socio-culture of large cities in Korea, especially comparing them in Seoul, Daejeon, Daegu, and Kywangju. The items of questionnaire are drawn from theories on each sector of new urbanization of large city in Western countries, that is, that of post-Fordism, of urban governance, of post-modernism, and of sustainable city. Some major findings of this questionnaire analysis are as follows. First, on the change of large cities in general, citizens think that the sectors of spatial structure, and of socio-culture of the cities were changed more than those of urban economy and of urban politics. Secondly, in the sector of urban economy, citizens recognize that the obstructing factors of development, that is, the lack of regional capital and the absence of head-quarter of large firms, which seems to be resulted from uneven regional development in the previous periods were much more serious than others, while acknowledging the importance of high-tech industry. Thirdly, in the sector of urban politics, citizens think that the centralized structure of politics and of political parties was still problematic, while acknowledging the importance of entrepreneur mind of urban governor. Finally, in the sector of urban socio-culture, citizens emphasize the development of telecommunication, the popularization of private automobile and the increasing use of credit card, as three major factors which have exercised major impacts on the development of urban socio-culture.

This paper is to analyze citizens' consciousness on urban changes, especially focusing on changes in urban environment, spatial structure, and urban planning, of large cities in S. Korea, that is, Seoul, Daejeon, Daegu, and Kwangju in the 1990s. Some significant points can be described as follows. First. The most important factor influencing on the change of urban spatial structure was the expansion of residential area inner and outside of cities promoted by the traditional construction industry, and not development of high-tech industries and their complex or location of multi-national firms which can be emphasized as major factors of new urbanization process of global cities. Secondly, citizens seem to have experienced improvement and deterioration of urban environment simultaneously, emphasizing regulatory environmental policy on the one hand, and recognize the necessity of sustainable urban development within given environmental capacity and restoration of destructed and polluted environment of cities. Thirdly, the building boom of new apartment complex was a major driving force of changing urban spatial structure, but it could neither alleviate a residential gap between the poor and the rich areas nor a relief of traffic congestion. Finally, the urban policy in general was felt somewhat improved by citizens, but not in sectoral details.

There is a general agreement that the global social-economic system is undergoing fundamental changes, which can be explained in terms of the transformation of production system from the Fordism to Post-Fordism since the 1980s. These fundamental changes have resulted in the 'new urbanization' process in the most of large cities in the developed countries. The aim of this paper is to identify the 'new urbanization' process in a large city in Korea that is, Daejon. For the propose, this paper tries to examine and conceptualize empirically the changes of economic, political, social-cultural, and spatial aspects of Daejon metropolis in the respect of 'new urbanization'. The major findings of this essay are summarized as follows. First of all, Daejon economy has experienced new changes, that is the development of service economy and high tech industry. But the old industry still remain important in the urban economy. Secondly, in the political aspect, new civil movements flourish in the city, while the political power of Jaminlyeon, a pro-conservative and narrow-regionalism party, once dominated this region, has decreased its influence. Thirdly. the original CBD of Daejon has been declined while new (sub-)CBBs have emerging in Daejon spatial structures. In conclusion, we can find some clues of the new urbanization process in Daejon, but this process is still quite slow and somewhat different from those of large cities of the developed countries.

Chemical analyzes were carried out the samples from roadsides of the Gwangju city. The purpose of this research is to investigate the concentrations and distribution patterns of heavy metals due to urbanization and industrialization in the Gwangju city This study area is not significantly contaminated based on the concentrations of Cd, Cu, Fe, Mn, Pb and Zn. However, the concentrations of the chemical elements analyzed are locally higher than those of serious contamination level indicated by Ministry of environment. The dust pH is in the rage of 5.60-7.09 and was generally neutral, and there are no difference in pollution area and nonpollution area. Chemical analyses utilized are dilution by 0.1N HCl. In result of analysis by the method using 0.1N HCl, concentrations of Cd and Cu are a little high in Gwangchondong of Seo-Gu. Concentrations of Mn and Pb are a little high in Buk-Gu and Nam-gu, and Concentrations of Zn are generally higher than average of soils. Zn, in the study area, keeps polluting greatly as Zn concentration of average is 150.9ppm. All of P.I values are lower than 1, it means heavy metal pollution is not serious.
