This paper is aimed that preparing to make good plan for great city ports, like Gwangyang port which is growing rapidly in Asia as a hub port. But I am worrying about the capacity of Gwangyang bay area to serve very great mission for the future, continuously. I hope that we are able to make good circumstances for our great ports. In this Gwangyang bay, we can realize that we may have some solutions for the traffic jam, because of the finite bay area. So I analyzed the rate of traffic jam that was derived from so many great ships to come and use the Gwangyang bay area. As a result, in recent year, 2005, 2006, ratio was growing rapidly, so we need so we need good works for this region.

Vietnamese cities have a high risk of flooding under climate change due to their geographical characteristics. In this situation, the urban area is expanding with rapid growth of urban population. However, the risk of flooding is increasing due to the increase in impermeable areas and insufficient infrastructure. This study analyzed the urban expansion trend at the national level in Vietnam for the past 10 years (2007-2017) by using the Urban Expansion Intensity Index. Also, this study selected Hue City as a region with a large impact of climate change and a rapid expansion and found the possibility of flooding in the urban expansion area. The result showed that cities have been expanded around major cities in the Red River Delta, Mekong Delta, and coastal areas. In the case of Hue City, the area with fast expansion rate has a higher expected flood area. It implies that the risk of flood disasters may increase if the urabn expansion is carried out without disaster prevention measures. It is expected that Korean urban disaster prevention policies such as urban climate change disaster vulnerability analysis system will be helpful in establishing urban plans considering climate change in the fast growing regions such as Vietnam.

While Jeju Free International City was promoted to overcome the economic crisis and build a new national competitiveness in the era of globalization, its development vision as 'the hub city of Northeast Asian economy in the $21^{st}$ century' has not been realized. This paper argues that Jeju Free International City to aim for the 'ideal free market model', 'neoliberal space of exception', and 'a new testing ground for neoliberal deregulation policies' has failed due to worsening of socioeconomic and environmental contradictions, growing conflicts in local community, and the logic of equity enforced by the central government. To support this claim, this article reviews the theoretical discussions of special economic zones, examines the shifts in the development visions of Jeju Free International City, and analyzes how Jeju has become a space of exception with the introduction of various exceptional policies and spatial mechanisms.

Micro hydraulic turbines take a growing interest because of its small and simple structure as well as high possibility of applying to micro and small hydropower resources. The differential pressure exiting within the city water pipelines can be used efficiently to generate electricity like the energy generated through gravitational potential energy in dams. In order to reduce water pressure at the inlet of water cleaning centers, pressure reducing valves are used widely. Therefore, pressure energy is wasted. Instead of using the pressure reduction valve, a micro counter-rotating hydraulic turbine can be replaced to get energy caused by the large differential pressure found in the city water pipelines. In this study, in order to acquire design data of counter-rotating tubular type micro-turbine, output power, head, and efficiency characteristics due to the diffuser.

The existing urban open space system of the German cities has an exellent frame, which is a result of the long history of its developing. The beginning time of that goes back to the end of the 18th century, as pri-vate gardens of feudal lords and the nobility became more and more public and public open space plannedwas appearing. Through the change from the feudal age to the civil society, the people's values on the urbanopenspace were growing. so that it had more social meanings. Since the Industrial Revolution in the secondhalf of the 19th century the environment of cities was getting miserable, what was the important cause ofthe birth of ideas and concepts of the urban open space type and its system.The fo1lowing concepts are they. which have influenced modern open space concepts of the cities InGermany decisively :'Garden Cities'.'Neighborhood'. 'The Model of Mohring, Eberstadt and Petersen','The Model of Langen'. "The Classified City','The Classified and Loosened City'etc.

Yanji city in China is a city most populated with Korean-chinese. This study is to examine architectural planning characteristics for Korean-chinese Elementary schools in Yanji city. Currently, this city includes nine Korean-chinese schools. This research has been processed with regards to three broad aspects. Firstly changing processes of school systems, secondly local distributions and networks of school facilities, and thirdly site plans, floor plans and elevations of school buildings were analyzed and examined for finding their characteristics. For this study, seven Han-chinese Elementary schools were also analyzed. The study result are as following: 1. Korean-chinese schools have followed national education policies and also maintained Korean-chinese native education methods. The schools have undergone merger and separation with Han-chinese Elementary schools. Three Korean-chinese Elementary schools in Japan Colonials, two schools in the period of the Republic of China foundation and its growing, and four schools in 1980s were founded. 2. Yanji city administers the networks of Korean-chinese school districts and Han-chinese districts separately. All school districts apply to lkm standard as attending distance. The networks are adjusted as per population change. 3. The characteristics of buildings' site plans, floor plans and elevations are simple. Layouts of the schools are - type or -type centered playground. Building plans show one side corridor type and 5 stories mostly. Elevations stress central parts. Various forms such as finger types do not appear in mass planning since the school curriculum and extracurricular activities are not seemingly active. Han-chinese Elementary schools have similar conditions.

In terms of climate change communities have only during the 1990s begun to recognize that all greenhouse gas(GHG) emissions are directly or indirectly generated locally, through acts of agency, production or consumption. This has provided a boost to the role of local places in the debate since GHGs can be allocated and made understood locally and hence form the basis for specific policies, programs, plans and projects. The objectives of this study are to define a framework for making Environmentally Friendly City through enhancing integrated energy-urban policies and present framework to do comprehensive evaluation on energy related policies response and also explore the interrelation between energy related activities in each sector and policy and applies to Seoul mega city in Korea. Despite the growing recognition of the seriousness of urban environmental problems and their contribution to global environmental and social concerns, most analysts continue to study cities in parts rather than as a whole; we study sectoral sub-systems such as transport, air pollution or energy. While specialization is useful for detailed thinking, we also need to see each issue in the context of how each city works environmentally, economically, socially and politically. We therefore need integrative approaches to study of cities and need to understand how they function as systems. These framework presented in this study allows an organized and systematic analysis. These research results can provide useful, credible and timely input into the urban planning process. This study will be a helpful exercise to draw some policy implications of other cities in Korea and also East Asia that are in a similar stage with the these cities and developing plans on how to address them.

The Korean Ministry of Environment and Daegu Metropolitan City are establishing the Korea Water Cluster, which will focus on promoting and escalating Korean water industries. The water industry, a future-oriented and promising business sector, is continuously growing each year worldwide, so the project is very timely. In reality, however, challenges still need to be addressed, such as accessibility, logistics systems, social infrastructures, and attracting good companies. For the Korea Water Cluster to be successful, those issues should be solved, but it is difficult to untangle the matters only with efforts of the Korean Ministry of Environment and Daegu Metropolitan City since some issues will require a great deal of both money and time. Therefore, it is important for the Korean federal government to administer support and finances for certain parts of the project, and for the Korean Ministry of Environment and Daegu Metropolitan City to take on other issues to ensure the Korea Water Cluster is successful long-term. The success of the Korea Water Cluster project will result in the Korea Water Cluster becoming a global hub for the future water industries.

This study analyzes the changes of lifestyle and urban spaces with the advent of U-City and tries to propose a direction of urban policies reflecting them. For this, it investigates lifestyle changes to predict the phase of urban spaces in the future. In a survey on urban functionalities with downtown as the main space of activities, it was expected that traffic for the use of these functionalities would be reduced. Traffic reduction was predicted to restrain downtown from growing and weaken the concentration of downtown activity. For the reorganization of existing spaces, in particular, public spaces would be changed to multi-purpose spaces in which various urban activities can be carried out using ubiquitous technologies. With the advent of U-City and the various changes of conditions, it is expected that the demand for land use and urban planning facilities would be altered by downtown and peripheries. A planning tool with a more concrete demand estimation of the future demand in individual areas of usage should be developed and it should be reflected in urban planning. Also, with the integration of functionalities so that more efficient land use will be possible, flexible designation of usage areas is necessary. Along with this, to prevent the decline of old downtown areas and provincial cities, the balanced installation of IT-related infrastructures will precede.
