Coastal settlements have a diversity of tangible or intangible local assets and are environmentally sensitive areas. The value of tangible or intangible local assets is often overlooked and there is no enough consideration for the inhabitants who have a various and acute stake in the development process of coastal settlements. The development of coastal settlements without consideration for the local circumstance, resident's needs, and local characteristics makes it difficult to achieve sustainable regeneration. There are also alienation, conflicts, and the loss of a authentic sense of place because of physical oriented development without regard to the social, economic, and cultural aspects. This research defines the components and types of coastal settlements and draws the characteristics of them around the fishery ports in Busan in the aspect of sustainable regeneration. It will be the important methods for an integrated regeneration including not only spatial and physical regeneration but also social and economic regeneration which has the preservation of local culture with living conditions, local economy activation, and community building. It will also provides the bases of sustainable development, attractiveness, and competitiveness of coastal settlements.

For shallow tunnel constructions, settlement of the ground surface is a main issue. Recent technical developments in shield TBM tunneling technique have enabled a decrease in such settlements based on tunneling with ground deformation controls. For this objective, the tail void grouting is a common practice. Generally surface settlements in a soil of low permeability occur during a tunnel construction but also during a long period after completion of the tunnel. The long-term settlements occur mainly due to consolidation around the tunnel. The consolidation process is caused and determined by the tail void grouting which leads to an excess pore water pressure in the vicinity of the tunnel. Because of this, the grouting pressure has a strong effect on the long-term settlements in the shield tunneling. In order to investigate this effect, a series of coupled hydro-mechanical 3D finite element simulations have been performed. The results show that an increase in grouting pressure reduces the short-term settlements, but in many cases, it doesn't lead to a reduction of the final settlements after the completion of consolidation. Thereby, the existence of a critical grouting pressure is identified, at which the minimal settlements are expected.

The purpose of this study is to clarify locational characteristics and the road systems of existing 22 old settlements in Cheongju downtown of Korea. These old settlements are classified largely into two types by geographical feature; Hill type located in ridge and Valley type in the valley from the ridge. The Hill type is further categorized into San-rock located on ridge and Gogae located on hillside, and the Valley type into closed large and small valley, that is, Daegok and Sogok by the shape and size of the valley. The road systems are classified into outer road, approaching road, inner road, and side road. In San-rock type villages, Inner road is changed side roads by new arterial road, and new ones become inner road. The outer road are almost cut off, but side roads maintain. In the case of the Gogae type, main road becomes inner road, maintain old hierarchical road, and in other cases, villages are formed around side roads derived from main road, and outer road and inner road are cut off. Among the Valley type, Daegok type maintains old hierarchical road, while for Sogok type, outer roads are cut off, and new roads are outer road.

This paper is to research the geographical language and location characteristics of 126 rural settlements focused on Miwon Myeon in the Integrated Cheongju City. The main results are as follows : Firstly, the geographical languages of 126 settlements are classified and categorized in the order of nature (91units, 72.22%), manmade and location related(35 Units, 27.78%). The geographical languages of nature, quite much in comparison with the others, are also classified into 39 'mountain', 46 'valley', and 6 'stream' units in location characteristics. Secondly, the geographical languages of nature have 46 'valley' units, much in comparison with the others. The open circular valleys are extended from Miwon Ri of town center to Gubang Ri along route 19. The closed valleys are placed in the west and north band of town center with a background of mountain range. The 46 'valley' units are distributed widely throughout these places. Thirdly, The geographical languages of 39 'valley' units except original 7 'valley' units are categorized with the secondary 'mountain'(rock and topography related), 'stream', 'manmade', and 'location related'. And so in considering the location characteristics of rural settlements, we will have to grasp the another meaning of the geographical language.

Before the industrial revolution architecture has been shaped by the natural and cultural inputs. Local constraints become more effective determinants of architecture in the rural contexts because by being disengaged from the webs of transportation and communication, rural settlements have achieved sustainability in difficult conditions. The examples of rural settlement and architecture have provided sustainability through integration with natural inputs within the geographical context because they have reached the goals of ecological design within the local constraints. Although this feature of the rural cultural landscapes has been emphasized frequently, tangible standards could not be developed in order to interpret their ecological design principles from the perspectives of the contemporary building sector and planning. However, the historical experience indicates that the sustenance of ecological performance can be possible as a result of integrated planning at the overall scale of the settlement. Therefore, the existing standards are not qualified for interpreting the rural contexts. This study develops a method for analysing, interpreting and evaluating traditional rural settlements and certifying new implementations in the rural environments in the light of the given literature review, discussion and methodological proposal.

This study aims to contribute to urban policy for more effective disaster prevention, as abnormal natural disasters are becoming more frequent. Up to now, the urban plan for disaster prevention in Korea merely includes basic principles and necessities of measures as an early stage. Furthermore, there are difficulties to make specific programs because the legal system, technical instruments, and financial supports are not sufficient. Therefore, this study figures out problems in the current plan related to urban prevention after analyzing the legal system and practices. Resulting from case studies in developed countries, the study draws significant implications, as follows: enhancing legally binding force; improving the procedures for the programs; establising technical infrastructure. It first suggests a way for the urban policy for disaster prevention by considering our local features comprehensively. It then defines the roles of central, local governemnts and research institutions, and the procedure for urban disaster prevention planning building on the individual roles. This study concludes that an emphasis should be placed on institutional tools necessary to publish technical guideline and establish the system so that urban planners more easily access to disaster risk information.

The landslide disaster damage has been increased by mountain development, leading to construction of educational facilities, medical facilities, petty industrial facilities, and large housing complexes. Therefore, effective regulation is required as an effort in urban planning solutions. For suggesting specific mitigation strategies on urban landslide, this study aims to define evaluation criteria for urban planning management of debris-flow disaster. AHP (Analytic Hierarchy Process), one of the multiple criterion decision making methods, was utilized in this study. This study makes use of 16 sub-criteria under the framework of hazard, exposure, and vulnerability, and well-planned expert survey measures their weights. The weights are also applied to evaluate each grid in urban space (min $10{\times}10m$) and classify it with red, orange, yellow, or green grade so that areas at higher risk are clearly identified. This study concludes that the suggested method is useful to support a strategies for urban planning management of debris-flow disaster, particularly in a GIS base.

This paper describes that estimation methods for the distribution of consolidation settlements to investigate the influence of distribution characteristics of compression index on the spatial distribution of consolidation settlements. When the variation of compression index is considerable, the spatial distribution of compression index is estimated using ordinary cokriging. The spatial distribution of consolidation settlements estimated by considering both the variation of compression index and void ratio (CASE-1) is different from the conventional mean value of all soil properties (CASE-2). The settlement of CASE-1 shows the larger variation at short distances rather than that of CASE-2. Whereas the spatial settlement distribution of CASE-1 is affected by the spatial distribution of compression index and the thickness of consolidation layer, the distribution of CASE-2 is significantly influenced by the distribution of the thickness of consolidation layer.

The one of the most important concerns in the design of the final cover system is to restrict percolation of water into the waste body. To minimize entering the water, the final cover system has the barrier layer that consists of a single compacted clay liner(CCL) or a composite liner with high density polyethylene(HDPE) overlying CCL. The HDPE as well as CCL can be damaged by landfill settlements. Therefore, this study was conducted to assess the effects of HDPE induced by settlements in the final cover system after closure. The results of the three test that is field test, lysimeter test in laboratory, and prediction of settlement represent that the HDPE in the final cover system is not pretty much affected by settlements and stable on settlements.
