  • Depletion of fossil fuels and sharp rise of international oil price as well as climate worming and frequent environmental disasters have required to strengthen resource(esp. energy) and environmental policy and discourse. And hence highly influential discourses and policies such as the concept of sustainable development and strategy for carbon regulation have been developed and pursued world-widely. But these concept and strategy have seemed to be subsumed in the process of neoliberalism, so as to have little effective results. This leads us to energy transition and energy autonomy or autarky as alternative strategic and normative concepts. Daegu has shown strong interests in urban energy problems relatively earlier than other cities, and developed the so-call 'Solar City' project. But it could not properly tackled with the problems, while tending to meet with the global imperatives. This paper considers urban energy problems and energy policy of Daegu with its significance and limitations, and suggests 4 principles for urban energy transition and autonomy with some concrete alternative measures; that is, the transition from fossil and nuclear energy to renewable energy, the transition from supply-led policy to demand side focusing policy, the transition from central governing energy system to locally distributed one, and the transition from market-dependent management to citizen-participatory energy governance.

  • The purpose of this paper is to provide basic information on how to make better policies that improves efficiencies of urban railways and to derive policy directions using DEA (data envelopment analysis) model. Through this paper, I can identify whether or not the urban railway service has an excellent performance, if there are any structural problems. I analyzed the efficiency by means of measuring the technical efficiencies of Korean urban railways, these were estimated with data envelopment analysis. The inputs considered are the length of urban railway lines, the number of staff, the operating cost, the number of cars, the number of stations, and the outputs are the cars movement, the traffic of passenger, and the revenue.

  • Since late 1990's the urban decline phenomenon has risen in most provincial cities in Korea. Many lively discussions have also risen about how to revitalize declined urban center. In small cities, especially resident participation is very important to revive their old vividness. The study then reviewed literatures published from 1995 to 2007 regarding resident participation in urban center revitalization for community reinvigoration. This study consists of four parts. The first part defined concepts of community and of resident participation, and included discussion about resident participation codes. In the second part, the problems about community formation and community facilities were scrutinized through preceding researches. The third and last parts suggested some propositions and strategies to draw resident participation into urban center revitalization.

  • Since planning of green-network is deeply being discussed, natural environmental disruption from an enlarged civilization is causing serious problems for urban communities. The purpose of this research is to support green-network infrastructure of Gangnam-gu, Seoul, considering ecological environmental planning for urban parks. The Methodologies for this study are landcover classification, NDVI and subjective analysis, and residents' survey. Findings of this research are as follows : 1) Based on the results, the area adjacent to Daemo mountain shows significant differences between 1985 and 1999. These results imply that the green space has been decreasing and deeply destroying. 2) Residents' survey shows that people want to live with wild animals and plants in the natural park. Future development planning of urban park should consider primary factors : ecosystem, increasing inhabitants' participation.

  • This paper aims to draw out the practical lessons for City Brand as aspect of urban spatial by urban regeneration project in Korea. Image of the City and City Brand is the most important element for the competitiveness of modern cities. This paper discusses the guide line or strategy of City Brand, its current status in Korea. It also examines the present Urban Regeneration in Korea, identifies the problems encountered in implementation, and suggests the solutions for strengthening urban competitiveness such as a City Brand. Also it emphasized that well planned invisible and physical environments, including story and land-mark facilities, are also crucial in making City Brand more attractive and competitive.

  • Poverty directly affects health and well-being, The poor population has a higher rate of chronics illness. higher infant morbidity and motality rates. shorter life expectancy. more complex health problems. and greater physical limitations resulting from chronic disease. In order to activate primary health care for the poverty in urban area the following measures should be taken : 1. Health center must be expended or establish subhealth center. 2. Health center must monitor neighbour's workplace's health management for their working population. 3. Health centers must do active home visiting nursing care for the urban-poor. 4. Health center must carry out flexible problem-centered practice according to the area. 5. For the urban-poor's health care must have organization of the health center & practice according to community's characteristics. 6. Public health care must be closely connected with welfare. 7. For the health care of the urban-poor must demand active community participation. 8. Health center is closely connected with Community hospital. 9. Active management of public health resource system is demanded.

  • During the structural design of urban over-track high-rise buildings, two problems are most likely encountered: the abrupt change of story stiffness between the podium and the upper towers, as well as the demand for train-induced vibration control. Traditional earthquake-resistant structures have to be particularly designed with transfer stories to meet the requirement of seismic control under earthquakes, and thus horizontal seismic isolation techniques are recommended to solve the transfer problem. The function of mitigating the vertical subway-induced vibration can be integrated into the isolation system including thick rubber bearings and 3D composite vibration control devices. Engineering project cases are presented in this paper for a more comprehensive understanding of the engineering practice and research frontiers of urban over-track high-rise buildings in China.

  • The last 30 years have seen a rapid growth in the number of supertall buildings across the world, with newly completed buildings continuing to rank among the tallest 100 every year. Chinese projects notably play a pivotal role in these constant updates. It is caused by the interweaving of population and urbanization, economic considerations, and further, a series of accompanying urban problems. This paper focuses on the world's 100 tallest buildings in the last 30 years, and compares this collection of projects across five years via the dimensions of height, distribution, function and structural material. The intention is to discuss and interpret the influence factors and developing trends, some of which have been apparent over a dozen years, while others are just beginning to take shape, thus to provide an opportunity to preview the types of supertall buildings in the future.

  • The Ministry of Land, Transport and Maritime Affairs has announced a policy which can enable the building of urban type housing with the use of a prefabrication method 2010. However, such may possibly be at standstill owing to the prefabrication methodology that has not been currently developed in Korea. Moreover, small households of consisting of one or two family members have been steadily increasing, but the small housing units in which they reside has been decreasing. Due to this situation, urban type housing has been proposed. To expand the propagation of such urban type housing and to promote prefabrication methods, the top priority project is to develop a technology that is able to reduce construction costs, as well as to shorten the actual construction period. In consideration of this prefabrication system for an avenue to solve such problems, a series of systems and policies for the fostering of prefabricated urban type housing has been proposed. This study is to review a series of methods, technologies and policies that are required for such urban type housing and henceforth, to utilize such as preliminary data for further prefabricated urban type housing.
