  • Due to the enormous amount of fills required, broken rock-fine grain soil mixtures have been increasingly used in the construction of high-fill foundations for airports, railways and highways in the mountain areas of western China. However, the compressibility behavior of those broken rock-fine grain soil mixtures remains unknown, which impose great uncertainties for the performance of those high-fill foundations. In this research, the mixture of broken limestone and a fine grain soil, Douposi soil, is studied. Large oedometer tests have been performed on specimens with different soil content. This research reveals the significant influence of fine grains on the compressibility of the mixture, including immediate settlement, creep, as well as wetting deformation.

  • Because of the international marriage of bachelors in the rural areas, there have been grown many foreign residents, the Multi-cultural families. For the improvement of multi-cultural families, the first important thing is their early settlement in Korea. For those foreigners' settlement, systematic approach to Korean education program is necessary. Second, multi-cultural families need support to maintain their basic lives safely. Agricultural education for the next generation is, moreover, also important for them. Third, healthy growth and training for the formation of the Self-Identity of their children are needed for those multi-cultural families too. Education for bring up their children as the global talents, the cost of private education and the one of bringing up children also have to be supported. Fourth, the improvement of understanding multicultural families is significant. Development and education of various programs to participate multi-cultural families are also required.

  • Although the WTO has fulfilled several key tasks it was set up to do - providing periodic reviews of members' trade policies, resolving disputes, supporting negotiations - with the notable exceptions of the Trade Facilitation and Information Technology agreements, WTO members have not been able to negotiate new rules on "bread and butter" trade policies. The importance of doing so was illustrated by the COVID-19 pandemic which saw widespread uncoordinated recourse to trade policy instruments. This paper highlights four reforms that would bolster the effectiveness of the WTO as a forum for trade cooperation: (1) improving collection and reporting of information on trade-related policies; (2) supporting analysis-informed deliberation to establish a common understanding of the need and scope for cooperation in specific policy areas; (3) putting in place a stronger multilateral governance framework for plurilateral cooperation between groups of WTO members; and (4) reestablishing an effective dispute settlement system.

  • Land was reclaimed at the waterfront in the Pluit area of Jakarta for a 90ha residential-cum-recreational development. The reclamation works involve construction of permanent and temporary dykes, fill placement, soil improvement, dredging of internal canals and marina, and construction of canal revetment. The site lies on 16m to 18m thick soft seabed deposits. Settlement of the reclaimed areas will result as a consequence of consolidation of the soft underlying sediments. In order to reduce post-construction settlement to within acceptable levels, a system of vertical drains and preloading was adopted. This paper describes the use of Fibredrain, a prefabricated vertical drain made of jute and coir fibres developed at the National University of Singapore, in the soil improvement works and a secondary use in the construction of perimeter dykes for the reclamation works. The construction of the perimeter dyke must be carried out in such a way that slope stability is on ensured. Bamboo rafts and bamboo clusters with Fibredrain inserted, and stage construction were employed to improve stability during the dyke formation for the Pantai Mutiara project.

  • The urban renewal type redevelopment project is a project to improve the urban environment for the recovery of urban functions and revitalization of commercial districts in commercial and industrial areas. Urban regeneration projects are not progressing smoothly. The urban renewal type is not so for landowners, who require a high level of professional knowledge and experience to carry out smooth projects. In addition, the core part of business conflicts can be seen as the problem of management and disposal methods. Therefore, as landowners, etc. become the actual subjects, the public will take charge of project execution, but all development gains and losses will be attributed to the owner of the land, etc.

  • The purpose of this study is to develop a policy for the use of libraries and the promotion of the reading culture by the characteristics of communities, along with changes in social environment. It, therefore, analyzed the general condition of libraries, infrastructures for libraries and reading culture and the environment including the relevant legal system in Chungcheongnam-do, and examined the actual conditions of inhabitants' (students and general people) use of libraries and reading culture, and librarians. On the basis of the findings, it proposed the policy for the use of 20 libraries and the promotion of the reading culture, by dividing Chungcheongnam-do into six regional settlement areas, discovering policy tasks for the use of libraries and the promotion of the reading culture and collecting suggestions from librarians living in Chungcheongnam-do, to reflect the characteristics of communities in Chungeongnam-do, and therefore, suggest a desirable policy agenda. To pursue the policy proposed, it is necessary to reinforce the role and the status of libraries representing for metropolitan regions and to secure adequate personnel and budgets, in addition to effort made by libraries located at regional settlement areas.

  • The purpose of this study is to look into current situations of urban-to-rural migrants' community participation and its relationship with rural life satisfaction. This topic is important because one of the main barriers to migration decision is job availability, especially in rural areas. Besides, rural areas need more human resources to support aging communities, as rural population is constantly decreasing. For this study, we used the methods of survey and in-depth interview with structured questionnaire. We met 121 respondents who were in community participation activities by the snowball sampling method in 10 counties nationwide. As a result, we identified community participation activities could contribute to urban-to-rural migrants' stable settlement and improving their satisfaction with rural lives.

  • Landuse maps are prepared from satellite imagery and field observations were conducted at various locations in the study area. Compared to the field data and NDVI and RVI thematic maps, NDVI is better than RVI, because it compensates for changing illumination conditions, surface slope, aspect and other factors. Clouds, water and snow have negative values for RVI and NDVI. Rock and bare soils have similar reflectance in both NIR and visible band, so RVI and NDVI are near zero. In forest areas with good vegetation cover, NDVI is high and landslide occurrence is less. But if annual and biennial vegetations are present and if cultivation practices are changed frequently, NDVI is medium and landslide occurrence is moderate. In areas where deforestation and settlement is in progress, NDVI is less and landslide occurrence is more. The NDVI FCC thematic map may be used as an important layer in GIS application for landslide studies. Analyzing other layers such as slope, rainfall, soil, geology, drainage, lineament, etc with NDVI FCC layer will give a better idea about the identity of landslide prone areas.

  • Concrete slab track was applied to the Gyeoungbu High Speed Railroad step 2 and the Honam High Speed Railroad. Concrete slab track incurs higher construction cost and lower maintenance cost than existing gravel track. For these reasons, the use of concrete slab track has increased in Korea. The biggest problem in the use of concrete slab track is repairing damage from settlement that can occur while trains are in service. High speed railroad design standards require allowable residual settlement of concrete slab track of less than 25mm. In order to satisfy the requirement of long term stability of concrete slab track, it is necessary to manage the secondary compression settlement within the allowable residual settlement. This study is to evaluate the secondary compression settlement with the variation of the secondary compression index, thickness of soft ground, and concrete slab track life. Statistical analysis is performed to determine the probability of distribution of areas where serious problems will be caused after the concrete slab track is constructed.
