After 1970-80's rapid economic and urban development, nowadays the old downtown suffers from the deterioration of physical environment, outflow of its function and cavitation of population. And this phenomenon makes urban regeneration as a new paradigm in urban development. This is the case of Myeongdong area (Jungang-dong, Monsung-dong), old downtown of Cheonan around rail station, in the same way. City government has tried many regeneration/ redevelopment projects on this area but all failed due to lack of feasibility. This study intends to suggest new viable strategic regeneration scheme of this area through research and analysis of TOD development, existing condition and problems. As a result, the area needs to be considered as a node that links bus terminal complex and central market place with walkable street. For regeneration of this area, a strategic development scheme of this area is suggested deploying private capital invested rail station, underground shopping mall, transfer center, culture complex and nature park with Myeongdong street mall.

In the era of diversity and creativity, autonomous regional regeneration is being emphasized. Local regeneration effects through local heritage utilization and the value of regional properties are rising. It is very meaningful to find a way to revitalize the urban regeneration system that can transform the facilities, spaces and industries in underdeveloped regions into opportune properties. This study explores the possibility of self-sustaining development by establishing an endogenous self-reliance system through the localization of industrial heritage. Competitive advantage strategies of regional properties are more important than regional comparative advantages. In the future, more attention should be paid to the intangible value of the city. A genuine city revival should be created as a place with cultural identity through artistic ecology, tradition, community, and aesthetics centering on people.

This study aims to find implications for urban economic regeneration strategies of local initiative by analyzing of promoting regional strategic industries, both Seongnam and Goyang in terms of regional industrial policy, institution and specialized service agency. The main results based on the case studies are as follows. First, It is a top priority to formulate the policy direction, such as selecting strategic industries and prepare means for improving it. It should keep reliability and continuity for inducing economic units. Second, It is necessary to consider the effectiveness and diversity of institutions. The institutions to be formalized by municipal ordinance and rules for making the successful implementing system of policies. It is necessary to implement strategic industry policy linked with the central government or public organizations for expanding of a diversity of policies. It is necessary to change in viewpoint on the deregulation and tax break for the private sectors as inducements to achieve the regional economy activation. Third, It is necessary to introduce the specialized service agency to improve an effectiveness and efficiency of institutions and accelerate a network within economic units.

Recently, TOD gains popularity as a traffic solution measure of high density urban regeneration projects. The purpose of this study is to investigate traffic impacts of high density TOD projects, and to identify the issues to be resolved. For a case study, it chooses Gangnamgucheong station in Gangnam area served by two subway lines, and designates 400m radius from the station as a site for high-density development. The MOEs chosen for this study is traffic volume, time, distance, speed, and mode share. The SECOM model is adopted for traffic simulation. The analysis results show that high-density TOD is an effective tool for traffic improvement even with only one station area being implemented. It is found that the traffic volume increases near the station in nature where high-density development occurs, but it declines overall in the rest of Gangam area. The total travel time and distance of passenger vehicles decline, meaning that the traffic condition becomes better than before. With regulation on parking supply, the improvement becomes more vivid. In terms of the changes of traffic speed, both alternatives show 4.1% increase in speed, but the difference between alternatives is not quite noticeable because of the induced vehicle demand driven to the streets with improved traffic condition. The mode share changes occur for the benefit of subway ridership, because the study station is equipped with two subway line services. When mixed with parking supply restriction, the impact becomes clearer.

The reality which cannot protect existing tangible intangible modern cultural heritage in Daejeon is makes historical value and identity of a city weakened and then, this leads to absence of the foundation of urban regeneration based on the history. References as recording inheritance indicates characteristics or identity of the area and they represent the physical mental symbol of the area; images of diverse structures or sceneries with historical or cultural characteristics are contents of urban regeneration based on history and culture, which can be utilized as historical sources to verify realness of disappearing modern cultural heritage. Therefore, understanding and utilization of modern cultural heritage through this study on regional archiving can be deemed to be the first stage to bring community spirit, affection and pride to local residents. In this connection, this study intends to suggest a policy direction not only to maintain realness of modern cultural heritage through preservation and utilization but also to expect formation of settling and fellowship as well as cultural economical effect from the viewpoint of urban regeneration.

Recently, as the social interest increase has been focused on new renewable energy system to build-up sustainable urban planning system, the related studies have been actively conducting. As well as in other areas, the construction area, which accounts for over 40% of the total energy consumption, clearly showed this tendency. Whereas, various landscape facilities applying renewable energy equipments have been manufactured and installed, systematic study available for planning and designing is rarely found in Korea. This study is expected to contribute to the landscape planning and designing by quantifying the energy-efficient and economic advantages of the renewable energy system for landscape facilities. For this purpose, the analysis on the energy-efficiency and economic values under the scenario that the current fossil power supply for the streetlights in urban parks in Seoul, Daegu, and Incheon were replaced by photovoltaic power generation were performed through RETScreen$^{(R)}$ a clean energy simulation program based on the NASA Satellite Meteorological Data. As a result, the generated power and the economic values vary depending on the climatic features of the appointed cities. This study will be used to build up the effective decision-making in applying the clean renewable system to the plan and design of landscaping.

Urban sprawl has been criticized due to its negative effects, including the encroachment of farmland and open spaces, the increase in traffic congestion and air pollution, the decline of central city, the decrease in social capital, and the unfairness of tax burdens on infrastructure and public services. This study measures urban sprawl in the capital region of South Korea where the characteristics of urban sprawl have been known to be different from those identified in the U.S. metropolitan areas. In particular, the study examines whether the capital region has experienced the decline of the central city with an expansion of low density residential development in suburban areas. Three measurements, the sprawl index with population density, the ratio of changes in urbanized areas to changes in population, and the population density gradient, were employed to measure urban sprawl, and GIS mapping and descriptive analysis were used to examine the central city decline and the characteristics of development patterns in suburban areas. The results show that the capital region of South Korea is moving to the American style sprawled development with the decline of the central city and an increase of single detached homes in suburban areas, implying that policy makers need to develop growth management strategies to prevent urban sprawl and its negative effects that many U.S. metropolitan areas have suffered from.
