  • Polymers, particularly plastics, have been widely seen as an existential risk to the environment due to their contribution to pollution, carbon emissions and climate change. Many argue that it is possible to substantially ease the threat of plastics by engaging the public in reducing their use in day-to-day life and implementing efficient domestic waste management strategies. On the other hand, polymers and plastics in building and construction are considerably less problematic, if not attractive. In fact, the applications of polymers in construction have been continuously expanding. This is partly due to the developments made in this area being implemented within a sustainable development strategy. In this paper, the main applications of polymers in construction have been revisited and an overview of the research topics in each application has been briefly presented.

  • Use of recycled aggregates in portland cement concrete (PCC) construction can offer benefits associated with both economy and sustainability. Testing performed to date indicates that recycled brick masonry aggregate (RBMA) can be used as a 100% replacement for conventional coarse aggregate in concrete that exhibits acceptable mechanical properties for use in structural and pavement elements, including satisfactory performance in some durability tests. Recycled brick masonry aggregate concrete (RBMAC) is currently not used in any type of construction in the United States. However, use of RBMAC could become a viable construction strategy as sustainable building practices become the norm. This paper explores the feasibility of use of RBMAC in several types of sustainable construction initiatives, based upon the findings of previous work with RBMAC that incorporates RBMA produced from construction and demolition waste from a case study site. A summary of material properties of RBMAC that will be useful to construction professionals are presented, along with a discussion of advantages and impediments to use. Several quality assurance and quality control techniques that could be incorporated into specifications are identified.

  • The construction can proceed in different ways according to the acquired profitability of the hospital during the construction and to the features of departments or areas. This study is an analysis of remodeling construction processes to resolve major tasks of remodeling. The remodeling strategies gained from this study can be summed up as follows: 1) Remodeling work in hospitals involves the acquire relocation of space through extensive area renovations and then moving back to the space, and lastly working on the empty space. Thus, it is more advantageous in terms of construction work to demolish the existing buildings than to acquire the relocation space through extensions or renovations. That is, demolition after the maximum utilization of the existing buildings is the most desirable in terms of space availability. 2) The construction methods for remodeling are two: a method of carrying out construction by dividing the plane areas into several individual ones and of working on it floor by floor. In case of ward areas, and the outpatient area, the construction proceeds after securing the relocation space and partially setting construction areas in order to minimize the decrease in profitability due to the smaller number of beds and treatment rooms during construction. If the outpatient diagnosis/ treatment area and the supply area relocate together with the ward areas, there may be extra expenses. Thus, doing construction by area, while partially operating those areas or after relocating the whole areas.

  • 본 연구는 건설경기지표와 경영성과지표의 상관분석을 통해 기계중심 전문건설업체의 경영안정화 전략을 제시하고자 하였다. 기계중심 전문건설업체는 건설수주액의 영향력이 다소 작지만 유동자산회전율에 장기적으로 영향을 미치고 있어 건설수주액의 변화에 따른 유동자산의 확보를 위한 경영전략이 수립되어야 할 것으로 판단된다. 즉, 유동자산의 운용을 증가시킬 수 있다는 것을 의미하며, 이러한 활동성 및 유동성의 확보를 통해 안정성 지표인 자기자본비율을 증가시킬 수 있을 것으로 판단된다.

  • In order to expand its entry into not only the domestic construction market but also overseas global markets, it is necessary to secure technological competitiveness, and as a fundamental measure, it is necessary to increase the proportion of R&D investment and establish and revitalize R&D organizations. Therefore, the purpose of this study is to analyze construction sales and construction R&D investment for global construction companies in Korea and Japan, derive implications, and provide basic data for government policy establishment and global construction company strategy establishment. As a result of analyzing R&D investments in construction companies in Korea and Japan, it can be seen that Japanese construction companies have higher R&D investment costs compared to sales compared to Korea. In particular, the proportion of R&D investment continues to increase year-on-year, strengthening global competitiveness due to technology development. In addition, Japanese construction companies have established a technology research institute to discover and conduct future R&D research such as advanced IT, disaster prevention, and environment.
