  • This paper aims to introduce a new type of mass transit system at new cities. A new mass transit system has been analysed in terms of three view points. 1) a new mass transit between a new city and surrounding cities. 2) a new mass transit inside a new capital, and 3) a traffic center connecting a new mass transit and other modes. This paper can be utilized as a guide line in doing the master plan for new mass transit at new cities.

  • 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.

  • Urban parks, as remnant patches, of two older cities and two new towns can be analyzed by a landscape ecological approach. The index of patch shape, the dispersion of patches, the mean edge length, and the mean patch size of parks of each city are ocmpared. The findings of this study are as follows : 1) The mean edge length of urban parks of older cities is longer than that of new towns : Seoul>Suwon>Bundang>Ansan. 2) The mean patch size of urban parks in Seoul is much greater than those of other cities : Seoul> Ansan>Suwon>Bundang. 3) The index of patch shape of urban parks of older cities is greater than that of new towns : Seoul>Suwon>BundangAnsan. 4) The dispersion of patches is in the order of Bundang >Ansan>Seoul>Suwon. The new towns have relatively even distributions of urban parks than older cities. Further research is required to find out the relationship between the index of patch shape and patch interior dynamics.

  • The objective of this study is to describe the influence of railway and railway station on the change of city structure in Korea in the early 20th century. In the 1900s, railway was constructed in Japanese concessions and in new pore cities such as Incheon, Busan, and Wonsan. In the 1920s, railroad construction became related with the cities, which could produce the corps. In the 1930s, railroad also became related to the colonial industrial cities. Traditional city structure was then completely changed because new city structure was focused on not Seoul but Japan or harbors towards Japan. So Korean cities, which were netted by railway, had become the subsystem of Japan in the early 20th century. Korean cities have developed on the basis of this system until 1945. For example, the twelve main cities were chosen through the relationship with Japanese life, and the provincial office governments moved near railroad stations. However nowadays, these cities have possibilities of being international cities, such as Incheon and Busan, because of the extroversion of these cities.

  • A few of new and large cities have been developed and developing at some areas surrounding Seoul, a capital city of Korea. Thus, commuters from new city to downtown are considerably increasing and the present network of road and railway will be short of transportation capacities. A special problem is that new cities are far from downtown than pre-existing new cities and the entering to downtown is required to a considerable time and cost. Therefore, a new conceptional transportation system has to be substitute with old-fashioned road and railway. This paper presents the feasibility of the deep & high-speed nonstop railway which is able to access to the downtown with ease and fast from new city. If the railway is located under deep position, indemnity cost of land will be notably down. If the railway runs with high speed and has a nonstop concept, the access time to downtown will be remarkably short.

  • During high speed economic growth period in Korea, our society has focused it's energy on the economic and social development based on the strategy of demolition and destruction of all our natural and man-made environment. In progress with that trend, our small cities in Korea also have just followed the metropolitan physical development pattern and considered that imitation of those metropolitan cities' or western cities' changes be the same meaning of "modernization". Therefore, our valuable urban and architectural heritages have been constantly destructed and that situation has been same in Anseong. Now in the new trend of environmentally sustainable urban design and at the new millenium period, we have to focus our attention on the retaining strategy of city's historicity as a city planner or an architect, and the first step for this strategy shall be to clarify the transition process of urban structure, especially of C.B.D. area of small cities since pre-industrial period.

  • Recently our society is changing from an information era to an ubiquitous era. The centralization of an ubiquitous city has been developing among the countries and cities competitively. At this point, a reconfiguration of proper network environment is very important factor for a city competitive power. The centralization of an ubiquitous city is progressing with two kinds of category divided into existing cities and new cities. For example, Unlike new cities, the existing cities should consider the physical space restriction of communication network configuration because they can not design an underground cord lining. This paper describes the comparison and analysis of ubiquitous proceeding cases between the existing cities and new cities. And also, we investigated infrastructure features of proceeding ubiquitous city which is regarded as a reviving concept for the existing cities. In addition, a political proposal of wireless network configuration is suggested to solve these problems for the ubiquitous city.

  • Nowadays, the condition of overcrowded cities has raised a question which is insufficient land in cities, and has gotten worse because of the influx of the population continuously. It has rapidly constructed a skyscraper increasingly that the solution to secure a living space against these overcrowded cities until 2000, but these are already positioning itself as one of the new type of residence. The necessity of skyscraper as facilities of residence inside cities has be available both a solution for overcrowded cities and a meaning for a symbol of its represented a landmark. However, constructing skyscrapers indiscreetly can not guarantee dweller's life environment, and it contains risks unless design and facilities criteria are provided. Now, a skyscraper as a new substitute constituting a living space in the future for overcrowded cities deals with a systematic correlation between a city and construction. Therefore the aim of this study were to indicate a method for improvement of dweller's life environment at skyscraper through establishing a point of reference to inculcate them for a sustainable skyscraper from now on.

  • Environmental issues had arisen following industrialization with rapid physical growth of city and its consequences: widened metropolitan areas, uncontrolled reconstructions of new metropolitan areas, many social issues, such as declines of existing metropolitan areas. Due to these issues, new development policies have been made in order to find identities and reconstruct new images of cities. This research aims to remind the meaning of conservation of modern construction and building re-use, and to identify values of modern architectures in the context of a city. Regeneration of cities is not only finding national identities, but also expecting to increase inflow of foreign travellers. However, this regeneration hasn't stayed sustainable, focusing only on short-term curing of the problem in limited areas. This work analyzes cases of modern architecture, historic buildings from various cultures: Western, Japanese, Chinese. The result of the analysis shows that the value of existing buildings and citizen participation is necessary to revitalize cities. Four characteristics have been also identified: historic relationship, spatial identity, spatial presence, and approachable efficiency. For a potential solution, cities need to be viewed from multiple perspectives to find a method to generate new vitality for a city whose values should be recognized as an asset through sustainable re-use, by transforming modern construction as a heritage.

  • The square tubed-reinforced concrete (TRC) column is a kind of special concrete-filled steel tube (CFST) columns, in which the outer thin-walled steel tube does not pass through the beam-column joint, so that the longitudinal steel reinforcing bars in the RC beam are continuous through the connection zone. However, there is a possible decrease of the axial bearing capacity at the TRC column to RC beam connection due to the discontinuity of the column tube, which is a concern to engineers. 24 connections and 7 square TRC columns were tested under axial compression. The primary parameters considered in the tests are: (1) connection location (corner, exterior and interior); (2) dimensions of RC beam cross section; (3) RC beam type (with or without horizontal haunches); (4) tube type (with or without stiffening ribs). The test results show that all specimens have relatively high load-carrying capacity and satisfactory ductility. With a proper design, the connections exhibit higher axial resistance and better ductility performance than the TRC column. The feasibility of this type of connections is verified.
