Reducing global warming potential has become important, and as one of those methods for reducing it, economic evaluation by applying ice thermal storage air conditioning system was performed. The floor area and height of the subject building was assumed $5,000m^2$ and 20 m. Absorption chillerheater system and air source heat pump system was used for comparing to the subject system, and payback period method was used to perform economic evaluation. Although the running cost of ice thermal storage system is reduced compared to two systems, the ratio is not significant compared to the increase of initial construction expenses, and payback period was calculated to be about 7.7 and 79.3 years. However, the heat storage system should be approached from the viewpoint of long term rather than the economic standard in the present standard.

As Additive Manufacturing (AM), so-called 3D printing technology, has become visualized, its potential for Mass-Customization, production costs and time savings has extended the scope of utilization to the architecture domain. Several cases that produced facilities, building elements and components using 3D printing technology have been announced mainly on the outside. There is also the development of foundation technologies including 3D printing-specific materials and equipment in Korea. As 3D printing technology in the architecture domain is currently in the early stages of adoption, realistic and systematic strategies are needed to advance it to the commercialization stages, considering the current circumstances of the industry. With this background, this study surveyed experts to investigate the status of the perception of 3D printing technology for adoption in domestic architecture industry. 3D printing technology is expected to be commercialized in areas of irregular-shape buildings and interior markets rather than general construction area. 3D printed products expected to be commercialized are limited to the level of building elements and the aesthetic factor is regarded as the most competitive factor. To enhance the possibility of the commercialization of 3D printed products, the 3D printing-specific construction method, related policies and systems are required along with the performance and stability of the materials and equipment.

근년, 철근 콘크리트조 구조부재의 열화 및 건축물의 용도변경에 따라 건축물의 보수 및 보강에 관한 공법의 개발 및 그 효과를 검증하려는 연구가 활발히 진행되고 있다. 이에 따라, 보강공법으로서는 경제성ㆍ시공성 면에서 우수한 탄소섬유시트, 아라미드섬유 시트, 유리섬유시트 보강공법 및 FRP판 보강공법 등 합성수지 접착제를 사용하는 새로운 보강공법들이 폭넓게 연구되어 현장 실용화되어 사용 중에 있다. 그러나, 이들 보강공법에 관한 연구는 주로 구조적인 내력 보강효과 산정에 관한 것이 대부분이고 보강후의 내화성능 및 내구성능에 관한 연구는 매우 부족한 실정이다. 이들 보강공법은 주로 에폭시수지계 접착제에 의하여 콘크리트와 보강재의 접착력에 의하여 내력이 전달되는 메커니즘으로 되어있어 화재가 발생한 경우 내화피복이 없다면 접착제 자체의 연소에 의하여 유독가스의 발생 및 접착강도가 크게 저하되어 그 구조적인 보강성능은 급속히 저하할 것으로 판단된다. 또한, 현재 이들 보강공사는 내화성능의 검토 없이 실제 시공이 이루어지고 있으므로 화재시에는 대형참사를 일으킬 위험성이 있다.(중략)

This study is for the investigation of form using the aluminum-compound metal frame(Aluminum frame reinforced panel : AFR panel) which is improved in the capacity in the wall-concrete structure in steal of using the existing form which has problems such as, excessive exposure of cement, the loss of labor when it is constructed or disjointed, and it's economical efficiency compared with that of EURO Form. AFR panel passes the KS F 8006 test, and as a result of field test, it's displacement is satisfied with Specification. And using AFR panel is more economical than that of EURO Form because saving labor cost which plays a major part in cost saving in formwork is more effective in retrenching total cost than increment of material cost.

Overseas construction industry has performed the leading role in the economic development. In this study, effect of international oil prices, GDP and price index, on the regional international construction contract amount is compared and analyzed. Overseas construction market received a devastating effect due to the 1997's economic crisis. However, the market has remained stable since 1998, and since 2005, the trend has been a surge in new orders.

1960년대 후반부터 시작된 경제개발계획과 주택정책으로 좁은 국토면적에 많은 주택을 보급하기 위하여 다세대 주택인 고층 아파트가 많이 신축되고 있으며, 고층 건물의 규모 및 그 수가 기하급수적으로 증가함에 따라 인근 건축물과 근접하여 시공하는 경우가 많아지고 있다. 구조물의 신축.증축 및 지하철 공사나 통신선로 등의 지하공간의 활용에 따라 타 공법보다 공사의 진행속도가 빠른 발파작업이 크게 증가하고 있으며, 도심지에서 인근 고층 구조물 및 건축물에 발파작업으로 인한 진동 및 폭음 등의 민원을 일으키는 직접적인 공해가 발생되고 있다. 본 연구지역은 부산 명장동의 "B초등학교 교지정지 및 교사 신축공사" 현장으로서 인근 고층아파트 103동, 104동 및 105동의 1층, 6층, 11층 및 16층에 계측기를 설치하여 발파작업으로 인한 진동 및 폭음이 층별로 미치는 영향을 검토하고자 하였다.검토하고자 하였다.

최근 경제구조가 고도화되고 생활수준이 향상됨에 따라 사회간접자본시설 및 각종 용도의 건축물에 대한 요구가 높으며, 특히 고층건물 건축시에 사용되는 리프트카의 수요 또한 증가되고 있다. 일반적으로 기계구조물은 사용기간동안 절대적 안전성을 확보하기 위하여 설계되고 있으나 실제 건설 현장에서 사용중인 피니언축에 균열이 발견되고 있으며 이로 인하여 피니언축 수리보수 기간동안의 공사중지로 공기지연 뿐만 아니라 리프트카 추락으로 인한 인명사고가 발생하는 등 그 위험성이 매우 높다. 이에 따라 각종 구조물, 설비 및 기기의 안전진단을 통한 유지보수가 중요시되고, 결함 검출의 정량화에 대한 연구, 기술 개발이 강력히 요구되고 있다.(중략)
