대한민국 건설현장에서 환경기술인 채용이 이루어지지 않고 있다. 제조업의 경우 대기환경보전법 제40조에 따라 사업자가 환경기술인을 임명하도록 명시되어 있다. 이와 반대로 건설 분야는 환경기술인 의무선임에 관한 법적인 사항이 존재하지 않는다. 국내 건설대기업의 경우 본사에 환경관리자를 채용하여 운영하는 사례가 있다. 하지만 본사의 환경관리자는 단위현장의 행정적인 업무 지원이나 법적 분쟁이 발생하였을 때 해결하는 역할을 할 뿐이다. 환경기술인의 의무선임은 건설현장의 일자리 창출뿐만 아니라 현장기술자의 업무를 분담하는 역할도 기대할 수가 있다. 향후 지구의 기후변화로 인한 환경 분야의 중요성은 점차 증가할 것이다. 이에 따라 공사금액 120억 원 이상의 건설공사에서 환경기술인을 의무적으로 선임한다면 청·장년층의 일자리에도 기여하며 기술자 본인의 업무영역에 집중할 수 있는 계기가 될 것이다.

This paper reviews on nano-materials as part of a study to apply nano-technology related technologies to the construction field. First, the synthesis method of nano-materials was examined. Secondly, the mechanical application method of nano-materials was investigated. Finally, the analysis method of nano-materials was investigated.

This study investigates the trend on application technologies of advanced composite materials and outlook on research development to the challenges associated with innovative applications of advanced composite materials in construction: 1) initiation of new construction materials; 2) development of rehabilitation techniques for aging infrastructural systems; 3) implementation of greener construction approaches; and 4) introduction of multifunctional advanced composite materials. This fundamental investigation will assure wide field implementation of advanced composite materials in construction.

Recently, industrial accidents rate has been gradually decreasing due to the development of safety management methods, but until now, the accident rate in the construction sector is higher than other industries. Large-scale construction sites are operating systematic safety systems to reduce industrial accidents. However, small and medium sized construction sites do not have systematic safety system and lack safety management ability, so that disaster is not reduced compared with large scale construction site. As a result, disaster prevention technology instruction system has been implemented to reduce the disasters of small and medium scale construction sites. However, in the case of a small construction site less than 2 billion won, there is little decrease in the accident rate, and in some cases, the accident rate increases. After the technical guidance system has been implemented, it is necessary to identify the performance and problems of implementation and to improve its effectiveness. In this study, we suggest the improvement plan to improve the efficiency of the technical guidance system by analyzing the problems and actual conditions of technical guidance operation in small and medium sized construction work sites.

Thermographic imaging based non-destructive evaluation proceeds measuring the defect or internal condition of civil structures. To demonstrate the feasibility of the method, the infrared camera system is applied to various specimens. The technique described in this paper may allow us to find their numbers, locations, and the extent of damaged steels from the measurement in the long distance. In addition, a reinforced concrete specimens with different penetration depths is tested using the active thermography method, and to study the influence on the detecting internal rebar in cooled and heated conditions. The experimental results demonstrate that thermographic imaging method is useful for detecting the damage of steel structures and the unknown rebar in the concrete.

The objective of this study is to improve safe execution of the management plan in Construction Technology Promotion Act. This research addresses the issue how to prevent the collapse of facilities under construction and after completion, improve the examination system, and execute Improvement of Safety Management Plan. To achieve this goal, research providing insights into understanding the ways in which creating and presenting safety checks and deploying safety training measures effectively is imperative.

This study of small ＆ Medium-Sized construction sites construction disaster prevention technology conduction-site visits from the map results report by the inspector on-site advice and technical guidance for the analysis of deficiencies and potential construction of disaster revealed the potential factors causing an accident as follows. As a results, Should not be a once a month visits. Therefore should be changed at least twice a month to help prevent accidents of this system is to be judged.

Safety accident rate of small-medium construction site is high. because of lack of safety management system, lack of safety management capacity, lack of investment for safety, Owner's insufficient awareness about safety. In order to improve this, Currently in Occupational Safety and Health Act, Construction site of amounts more than 300 million won less than 120 billion (architectural),150 billion won(civil) mandatory subject to the technical guidance on construction accident prevention. Context of construction accident causes with construction accident rate relationship analysis and case analysis of technical guidance, through a survey of stakeholders in the technical guidance drawn the problems of the construction accident prevention technical guidance system and ways to improve on this.

By the exhaustion of natural resources and the aggravation of the food situation, many countries are going ahead with development of the ocean space and ocean resources. To expand the border of human life, it is necessary to develop the underwater space. To perform these objectives, it is required to construct and secure a seabed base. The construction of a seabed base will also be the motive power for economy growth in the future. The key technologies to construct a seabed base under high pressure and low temperature conditions are the extreme engineering technologies and they are some parts of space engineering. They are also key technologies to survive when a worldwide-huge disaster attacks the earth. In this study, the necessary technologies for the construction of seabed base were surveyed. And the surveyed technologies were categorized by phase 1 and phase 2, which were defined by construction depth and size, and possible time. The surveyed results showed that it is necessary to construct a seabed base and develop a new constructional material and energy supplying method.

민간업체의 기술개발의욕을 고취시킴으로써 국내 건설기술의 발전을 도모하고 국가 경쟁력을 제고하기 위하여 건설기술관리법에 의하여 건설신기술지정제도를 운영하고 있다. 해당 법에서는 신기술로 지정받은 기술에 대하여는 일정기간동안의 해당기술을 보호할 수 있도록 하고 있으며, 해당 기술의 사용자에게 기술사용료를 요구할 수 있도록 규정하고 있다. 이처럼 건설 신기술 지정제도는 특허제도와 유사한 형태로 기술을 보호, 활용할 수 있는 제도로 운영되고, 해당 기술의 설계 반영시에는 그 기술의 사용료를 일정 요율로 책정하여 운영토록하고 있다. 본 연구에서는 건설신기술 지정제도와 특허제도와의 차이점을 살펴보고, 표준 설정에서 활용되고 있는 RAND 조건과 전통적 경제학에서의 가격차별 유형을 고려하여, 건설신기술지정제도의 운영 취지에 맞는 운영 방안을 제시하고자 한다.
