The rebuilt and redevelopment projects conducted these days surely have invited overpopulation. Its one of the culprits is the municipal ordinances which allow the floor to site area ratio to increase from 200% to 400% in a decade and the adjacent distance ratio from 1.25 to 0.8 times of height of building. Possible solutions for the overpopulation problem are as below. - The floor to site area ratio should be regulated adaptively according to various regional localities. - Draw back the capital gains coming from a rebuilding project For evaluation process; - Select a suitable plan from plurality of proposals - Gradually encourage projects towards remodeling system in the near future

Cities should be developed and managed deliberately since reckless development and selfish expansion deteriorate the quality of life in the cities by creating various problems in transportation, residence and environment. In particular, the semi-agricultural zones have been designated in order to address such problems as the overpopulation caused by the influx of people into the cities and promote balanced regional development and eco-friendly cultivation of the land across the nation. But the problems of metropolitan areas, such as the overpopulation and lack of infrastructure, are spreading even to the semi-agricultural zones, which should be the last areas to be developed into cities. We should blame the indolence of our policies on land first, rather than the selfish cities that slip from the grip of the law. This study concludes that the self-agricultural zones should be developed and managed with plans by the public sector rather than the autonomous development by the private sector.

In the context of sustainability which is understood as equilibrium among three elements; human, space and time, the imbalance within the Seoul metropolitan area hinders its own area or the nation from development. Claims for the balanced development in the area are set up on the premise that there is a locational order of priority among the zones named 'overpopulation suppression', 'growth management' and 'conservation'. Based on the systematic consideration of competitiveness this study adopts the premise as a research hypothesis. Factor scales derived from the factor analysis, a kind of multivariate dependence analysis play an important role in this research process since they are measured by interval-ratio level and can be used for dependent variables in the statistical analysis. The hypothesis test carried out by means of the analysis of variance(ANOVA) concludes that the hypothesis assuming no difference in the competitiveness is rejected but the alternative hypothesis of the locational order mentioned above should be adjusted. Eigenvalues derived from the factor analysis could be used as weights for aggregate factor scales and the scales show that the priority is in the order of growth management - overpopulation suppression - conservation zones. This finding has also a significant implication that the countermeasures to cope with the lowering of the competitiveness resulted from the continuous and absolute restraints should be provided. And strategic approaches which are composed of key factors for each zone are deducted from in-depth review. (1) overpopulation suppression zone; health-welfare, educational base, public service factors, focusing on health-welfare one, (2) growth management zone; public service factor and (3) conservation zone; health-welfare, educational base factors, also focusing on health-welfare one.

The overpopulation phenomenon and complicated various daily life in the city can't presuppose a loss of lives and properties by fire as in today. Especially, mutual relation of buildings and road of the urban preventive dimenson share with important roles and function. This thesis analyses next two articles. First, this study examines improvement counterplan by urban preventive demention centering around theory. Second: as a case study through statistics of fire is Seoul Namdaemun market propose improvement plan in urban preventive dimension.

Deterioration of the outdoor thermal environment in urban areas such as heat island has become worse due to urbanization and overpopulation, etc. In this study, a new method which is coupled simulation of convection and radiation to evaluate outdoor thermal environment in urban area will be proposed. Because the solar radiation affects on outdoor thermal environment massively, therefore the radiation calculation is very important in outdoor thermal environment prediction. The coupled simulation proposed in this study can assess the outdoor thermal environment with accurate.

Korea rapidly arranged urbanization and overpopulation with high growth of economy and all kinds of decrepit facilities are scattered all over the downtown. If there is a strong wind in fire, fire is rapidly increased by various fire spread factors. And Korea cannot build prediction model of urban fire combustion phenomena because there is no studies that physically explains the suitable flame phenomena for its real state. In this study, based on the Japanese Urban fire simulation to target the traditional market area and suitability of fire risk assessment were reviewed.

Subway has been used one of major public transportations because of overpopulation and heavy traffic problems in the metropolitan areas. So, the air pollution has been serious. In this study, continuous date of PM-10 (particles with aerodynamic diameter < $10{\mu}m$) and heavy metal concentration measurements for winter, spring and summer. These measurements have been carried out in the outdoor, concourse, platform, tunnel. The study results showed that the average seasonally concentration of PM-10 particles were $141.57{\mu}g/m^3$ in winter. $129.34{\mu}g/m^3$ in spring and $122.73{\mu}g/m^3$. The average concentration of PM-l0 particles at indoor higher than outdoor. The concentration of Fe, Cu, showed the largest peak concentrations during the respective season.

Subway has been used one of major public transportations because of overpopulation and heavy traffic problems in the metropolitan areas. In this study, continuous date of PM-10(particles with aerodynamic diameter < 10$\mu\textrm{m}$) and heavy metal concentration measurements for autumn and winter period were analysed. These measurements have been carried out at the outdoor, concourse, platform, tunnel. The study results showed that the average seasonal concentration of PM-10 particles were 181.01$\mu\textrm{g}$/㎥ in autumn and 129.03$\mu\textrm{g}$/㎥ in winter, respectively. The concentration of Fe, Cu showed the largest peak concentrations during the respective season.
