Environmental issues had arisen following industrialization with rapid physical growth of city and its consequences: widened metropolitan areas, uncontrolled reconstructions of new metropolitan areas, many social issues, such as declines of existing metropolitan areas. Due to these issues, new development policies have been made in order to find identities and reconstruct new images of cities. This research aims to remind the meaning of conservation of modern construction and building re-use, and to identify values of modern architectures in the context of a city. Regeneration of cities is not only finding national identities, but also expecting to increase inflow of foreign travellers. However, this regeneration hasn't stayed sustainable, focusing only on short-term curing of the problem in limited areas. This work analyzes cases of modern architecture, historic buildings from various cultures: Western, Japanese, Chinese. The result of the analysis shows that the value of existing buildings and citizen participation is necessary to revitalize cities. Four characteristics have been also identified: historic relationship, spatial identity, spatial presence, and approachable efficiency. For a potential solution, cities need to be viewed from multiple perspectives to find a method to generate new vitality for a city whose values should be recognized as an asset through sustainable re-use, by transforming modern construction as a heritage.

Purpose - Urban agglomeration construction is one of national strategic plans to accelerate the development of industrialization and urbanization in China, which has threatened the eco-environmental quality at the same time. This paper selected the urban agglomeration in the middle reaches of the Yangtze River as the research area. Research design, data, and methodology - The the slack-based measurement (SBM) model considering undesirable outputs is applied to measure the eco-efficiency of this urban agglomerations during 2006-2015. Results - The empirical results show that average eco-efficiency of the urban agglomeration in the middle reaches of the Yangtze River is 0.595. Regional ecological development is unbalanced. The highest eco-efficiency is recorded at Wuhan Metropolitan Area, and the lowest one is at the Changsha-Zhuzhou-Xiangtan City Group. Energy consumption and waste dust emissions are the key factors led to ecological inefficiency. Based on this, potentials for energy saving and waste dust reducing are calculated. Conclusions - Finally, this study provides policy implications targeted to promote the coordinating development of economy and eco-environment under the construction of urban agglomeration.

This paper is to investigate the change of the period of hot weather concrete with elapse of age based on climate data. Climate data for 30 years and 5 years are used respectively. Determination of the period of hot weather concreting on architectural execution in Korea according to the specifications of AIJ, KSCE, and ACI are discussed. According to the research, the period of hot weather concreting with each specification in most regions lasts over 35 days. Compared with the period of cold weather concreting in hillside and inland area, coastal areas have shorter period in the same latitude. The period of hot weather concreting tends to decrease with high latitude. As expected, with the elapse of age, the period of hot weather concrete exhibited to decrease, especially, big city like Seoul, Busan etc had remarkably increased period by as much as a week. This is due to the global warming and industrialization effect with the elapse of age.

Recently construction work in Korea, demands of favorable condition ground had been increased with industrialization acceleration and economic growth. However, because of limited land space, it was so hard to ensure favorable condition grounds that construction work proceeds until soft ground area on plans of road, railroad and industrial complex. In this case, soft ground improvement was required such as a stone column method. Stone column method, making a compaction pile using crushed stone, is a soft ground improvement method. However, stone column method is difficult to apply to the ground which is not mobilized enough lateral confine pressure because no bulging failure resistance. Hence, in present study, evaluates the stone columns reinforced by geogrid for settlement reduction and wide range of application of stone columns. Triaxial compression tests were conducted for evaluation which is about behavior characteristics of stone column on replacement rate. Then, 3-dimensional numerical analysis were conducted for application of stone column reinforced by geogrid as evaluate behavior characteristics and settlement reduction effect of stone column reinforced by geogrid on reinforcing depth change of geogrid.

The river environment of many streams in Korea has been deteriorated through the rapid industrialization and urbanization since the early 1960s. Deterioration includes single-purpose channel works for flood control and dense riparian land uses such even as the covering of the channel, as well as water pollution. As a result, many streams have lost their precious river environment such as ecological habitat, river friendliness and riparian scenery. In the early 1990s, however, the necessity of restoring those channelized streams was felt among the river engineers as well as environmentalists in Korea. This article describes a summary of the literature review of the stream restoration guidelines and relevant publication including those published in Japan, Europe and USA. A special focus is on the Stream Corridor Restoration, which was recently in the USA in 1998. First, the meaning and background of stream restoration is reviewed. Last, a draft of the contents of the stream restoration guideline, which is being developed by the authors and their colleagues, is briefly introduced.

In Korea, the quantity of waste is excessive as a result of increases in population and consumption following industrialization. This has resulted in urban environmental problems, a shortage of landfills and pollution around landfills. Thus, there is a need to conduct research in order to find an effective long-term alternative. In Japan, there are more landfills at sea than there are on land. Based on projections for Korea, on-land landfills in the metropolitan area will be filled to capacity by 2020 and then be closed. This research recommends the construction of landfill sites at sea as an alternative waste disposal method. Its findings show that the most the suitable sites for landfills within the Seoul metropolitan area are the regions around Jangbongdo Island and Mueido Island. It also suggests that the best way to transport waste is through the Kyungin Canal from the middle collection center to the lower Han River. The estimated cost of constructing an at-sea landfill to be used for 50 years is approximately two trillion won, with a total construction time of 10 years. In the future, further research related to this study will be conducted in order to ensure that environmentally-friendly landfills are built.
