  • The KOESWall system that minimizes the horizontal deformation of reinforced wall effectively was developed bt E&S Eng. Co., Ltd. in 1999. Due to its systematical feature i.e. isolated construction method. KOESWall system is able to use as temporary structures more economically without the facing block. In this report, it is shown that the case history of KOESWall as a temporary soil retaining structure and the field measuremnets.

  • This study intends to conduct a thorough research and analysis on the designated temporary residential facilities for the disaster victims in order to bridge the gap between the temporary residential facilities for the disaster victims in country and city, and understand the current status of the designated temporary residential facilities for the disaster victims in rural and urban areas. As a result, the designated temporary residential facilities for the disaster victims in urban areas are bigger and have higher capacity, implying the necessity to designate facilities in rural areas that can accommodate larger number of people. As to the analysis of the representative temporary residential facilities for the disaster victims in rural areas, different regions had different types of designated facilities and the number of facilities also showed big difference depending on regions. So it is believed that local governments should improve the process and system of designating temporary residential facilities for the disaster victims.

  • Glass-fiber reinforced polyester(GFRP) composite material is a promising alternative to existing construction materials such as steel, concrete and wood. One of passible applications of GFRP composite material is to build temporary bridges by assembling GFRP composite decks. In this paper, we develop a system of temporary arch bridges that can be built by easy assembling of GFRP composite decks. For this purpose, several types of temporary arch bridges are suggested and verified by FE analysis.

  • A study was performed to determine the optimum height for an arc air gouging of temporary attachments, which were attached at the pressure vessel made of low alloy steel. Frequently, the crack occurred in the base metal by the excessive heat input during an arc air gouging process to remove the temporary attachments. A numerical analysis by 2-dimensional finite element method was performed to calculate the temperature distribution in the base metal during the removal of temporary attachments. And then the mock-up test was performed to verify the numerical results. Numerical values showed good agreement with the experimental results. These results indicated that the defects due to the excessive heat input during an arc air gouging were dependent on the height of temporary attachments remained above hie main products.

  • The artillery fire accident in Yeonpyeong Island showed that the man-made disaster caused by the domestic political conditions as well as the conventional natural disaster can occur in Korea. Especially, it can be known that the whole community can be abandoned despite of a small scale of practical damage in residential district and the resulting large scale of refugees can be produced in the nation. This study investigated the real condition of temporary housing which has been provided at the Island. Firstly, in the theoretical review based on the literature study, the content on the background of temporary housing, the providing procedure of its concept, the status of supply, etc. has been considered. And it researched the current condition of the entire temporary housing through the questionnaire and interviews targeting the residents in the Island. So it purposed to make use of the results as a plan and design for future temporary housing against disaster.

  • The high-rise building construction field in the urban area is short of working space because it is surrounded by adjacent buildings and nearby roads. The insufficient space causes problems of interference and conflicts in transporting materials and working at the site. These problems can be resolved partly through the proper selection and layout of temporary facilities. A method proposed in this paper supports a decision-maker to evaluate and select the alternatives of temporary facilities plans by establishing and analyzing processes and influence factors of them. Knowledges considered in planning temporary facilities layout are structurized and a program is implemented for a field manager. Case studies are performed to evaluate the feasibility and applicability of the proposed method.

  • With the increasing popularity of dental CAD / CAM, the kinds of materials that can be used and the range that can be utilized are also increasing. One of the biggest advantages of a dental CADCAM is that you can make a final prosthesis with one visit, but in case of zirconia or a complex aesthetic prosthesis, it is often difficult to make it in one day. In this case, temporary PMMA material can be used to provide a temporary crown with aesthetic and functional properties to the patient and can be used as a test crown or template for the final prosthesis. And if you are with a 5-axis milling machine in a clinic, you can make a temporary crown precisely to a large extent in a short time. In this article, various applications and clinical cases of PMMA temporary crown in the clinic will be presented.

  • Generally, main girders and steel piers of temporary bridges form the steel rahmen structure. In this study, the rational stability design procedure for main members of temporary bridges was presented using a 3D system buckling analysis and second-order elastic analysis. Six types of temporary bridges, which can be designed and fabricated in reality, were chosen and the buckling design for them was performed in consideration ofload combinations of dead and live loads, thermal load, and wind load. Effective buckling length of steel piers, transition of 3D buckling modes, and effects of second-order analysis were investigated through a case study involving six temporary bridges.

  • Temporary constructions are defined as constructions for temporary use, but frequently they are used long like permanent constructions and connected with main constructions. In this case, fire hazardousness increase. But there is no way to control this hazard in our system. This study include investigation of present related law survey about sample complex, collection of related lawsuit result and estimation of hazardousness of each contemporary construction type. The conclusion is that the article that specify distance between main construction and temporary one should be created in the architectural law. Or to apply fire service law to area of temporary construction, fire service law should be changed properly.
