  • ISCLT3 model was applied in Seoul metropolitan area to investigate the source-receptor relationships among 17 cities in the Kyonggi Province. For the purpose of the model simulation, emission rates of NO$_2$, SOx, and PM(sub)10 were prepared for grid scale with 1$\times$1 km, and receptors were located on every 2$\times$2 km grid. Meterological data for the last 10 years(88~97) were used as input data. According to our study, NO$_2$ concentration of the cities ranged from 10 to 45 ppb with the highest value appearing from Puchon city. The concentrations of SOx and PM(sub)10 concentrations fell in the range of 5~20 ppb and 20~70$\mu\textrm{g}$/㎥, respectively. It was also found out that air quality in one city can be affected greatly by the air pollutants originating from other cities.

  • This study was conducted with the aim of confirming the relevance and effect of the characteristics of the cities and cities in the neighborhood area, focusing on the sale price per square meter of apartment. Specifically, it was intended to determine whether cities in the relevant city and neighborhood area have differential characteristics between the metropolitan area and the non-metropolitan area, whether industrial characteristics, urban planning and development project characteristics, and location characteristics. Comparing the research results of the city and metropolitan area, it was found that there was a correlation in all areas of population characteristics. Industrial and urban planning projects and development project characteristics sectors are not significant in the city, but they appear significant when analyzed in the urban area of the year. When classifying and analyzing the metropolitan area and the non-metropolitan area, both the metropolitan area and the non-metropolitan area were significant in the population sector, and only the distance from Gangnam-gu was significant in the local sector. Since the population is concentrated in the Seoul metropolitan area now, the sale price per square meter of apartments is also concentrated in the Seoul metropolitan area, which is believed to result in such a result. This is judged to be an analysis that appears because the characteristics of the developable status of the metropolitan area and the non-metropolitan area are different. Accordingly, this study shows that the characteristics of neighboring areas as well as the city should be analyzed when analyzing the factors affecting the sale price per square meter of apartment, and suggests that housing market monitoring needs to be carried out together.

  • Since the 1950s, many of the traditional industrial cities of advanced economies in Europe and North America were affected by a series of de-industrialization. The de-industrialization process, characterized by company shut-downs and massive lay-offs, has resulted in high unemployment rates and massive redundancies in physical infrastructure. Since the 1980s, many of the old industrial cities have attempted to overcome such problems. However, it has been found that not many of the cities are found to be successful. The City of Dortmund, one of the core cities of the large German industrial conurbation of the past, the Ruhr, is found to be an exceptional case demonstrating a clear success in overcoming deindustrialization problems. The City in fact strategically pursued transforming backbone of its economy from steel-making, coal-mining and beer-brewery to high-technology and future-oriented industries, based on microsystems, biomedical, electronic logistics and information technology. This paper attempts to analyse the processes and outcomes of transforming Dortmund beginning from the 1980s to articulate the roles of the agencies contributing to the success.

  • This study was analyzed the distribution tendencies and statuses of development projects for EIA projects. According to the result of this study, in the annual analysis, a number of consultations and areas have shown increasing trend across the board. In the project type analysis, there are development project types; urban development, industrial complex, sport facility installation, resort complex development, road construction, which have a lot of developments. In the cities analysis, a number of consultations were about 53% on the top 5 cities, the areas were focused on 75%, and the development projects were concentrated in the southern distribution of Gyeong-gi province. The development axis, from 2004 to 2006, was C-type, but it was extended to O-type until 2010. Therefore, the development will expand into nature conservation zones and forest areas to the east. The development restriction area will be disappeared gradually because the development density of the surrounding Seoul city is more advanced, and we could predict that may be accelerated conurbation between the neighboring cities. Thus, when the development project is located, it would be reviewed difference in existing development project type, project size, and concentration in each city on the basis of environmental capacity.
