As contemporary building construction type is getting higher and deeper,construction equipment usage is getting more, and related fatal accidents are on an increasing trend. In these days, due to the deteriorating construction business circumstance, job finding problem of equipment operator, and dumping contract, equipment lease suppliers are putin jeopardy. In high-rise building construction, especially tower crane, mobile elevated work platform and other High place operation cars among construction equipment cause many critical accidents because of drop supply of construction biding bringing out dumping contract could cause unsafe and poor construction management. Because of this, a method was drawn which could grasp the present state of construction equipment management and manage safety of the equipment more easily for accident prevention by choosing 2 kinds of Construction equipment which cause safety accident frequently among the equipment mainly used in construction site. This study suggested a method about construction equipment safety management using ‘‘smart phone’ base which could be used in safety management for construction equipment by whomever in construction site. After attachment of QR code included safety checklist, It became possible that site managers could check more efficiently by scanning with their smart phone when they inspect equipment. Moreover, by the construction interested who didn’t know what and how they have to inspect could point out unsafe condition in the early stage of equipment entering or take unsafe one out of the site by using new smart phone safety checking system is installed, it became possible that critical accident caused by construction equipment was prevented in advance.

Risk Assessment, a basis of health and safety management system, is an calamity prevention activity which regularly measure the level of a risk to passively improve potential hazard. A problem, the assessment not being improved to be applied to the construction work site where requires diversity and complexity, causes the assessment to be inefficient to bring quality results. A study on the investigates and compares the surveyed degree of recognitions of workers who works in companies executing the risk assessment By the investigation and comparison, it is expected to bring the better solution for early and efficient application for those companies which are not taking the risk assessment.

몽골은 석탄 매장량이 매우 풍부하고 석유연료를 전적으로 수입에 의존하기 때문에, 석탄액화플랜트 건설에 필요한 충분한 여건을 갖추고 있다. 본 연구에서는 몽골에 하루 10,000배럴의 석유연료를 생산할 수 있는 석탄액화플랜트를 건설할 경우에 대한 경제성분석을 수행한다. 먼저 기존에 있는 산업계의 석탄액화플랜트 프로젝트 데이터와 학계의 연구결과를 토대로 몽골 석탄액화플랜트 건설에 필요한 비용과 기대수명, 그리고 예상 수명기간 동안 운영했을 때 발생하는 운영

Recently, carelessness on safety management in construction sites has caused a sharper upward trend in accidents and disasters, compared to the past. Therefore, this study analyzes the causes of accidents that occurred on construction sites in the year of 2007, and proposes preventive measures. The construction industry had a heavy death rate with 279 out of 418 deaths from falls in all industrial sites, accounting for 66.7%. And the causation analysis found a particularly high incidence of temporary structure-related accidents, with falling off scaffolding as the most common cause of accidents. According to the causation analysis of fall-down accident cases, accidents induced by protrusion on construction sites are a big contributor resulting in the deaths of 312, accounting for 74.8%, which is deemed to be due to site disorderliness. And to remove floor protrusions and to secure workers' traffic line and safety, neat and thorough site arrangement is necessary. Against collision, efforts must be made to prevent equipment-pedestrian crashes on site, which necessarily requires emergency lamps, alarm bells, and safety poles and blocks to be installed, lighting systems to be improved, obstacles to be removed, site supervisors to be assigned to construction equipment works, and workers to be more intensely trained and supervised.

아산만 인근해역은 최근 20여년 넘게 실시된 각종 방조제 공사가 저서동물의 군집구조에 영향을 주는 것으로 알려지고 있지만, 이에 대한 연구는 충분치 않다. 그러므로 본 연구에서는 화옹방조제 건설 이후 아산만 대형저서동물의 군집구조에 영향을 주는 환경요인을 분석하였다. 대형저서동물 채집은 2007년 8월과 2008년 2월에 아산만 주변 해역 22개의 정점에서, 스미스 맥킨타이어 그랩(Smith McIntyre Grab, 표면 면적: 0.1m2)을 이

The Project of Jordan Research and Training Reactor (JRTR) officially launched in Aug. 2010. JRTR is the first made-in-Korea nuclear system to be built abroad by year 2015, and Korea Atomic Energy Research Institute (KAERI) is responsible for the design o

Korea enacted the occupational safety and health law in order to prevent industrial accidents in 1981. Led by ministry of labor, occupational safety and health support services policy has been built through government-affiliated organizations, research institutions and academic research. Korea's accident rate has remained at 0.7% for last 10 years despite continuous efforts over the last 30 years. These results means that the occupational safety and health support services policy conducted by the government have reached their limits. Therefore, the necessity of assessment about occupational safety and health support services policy is proposed. The main objective of this study, through the IPA analysis, is to grasp the point of worker's needs about occupational safety and health support services policy and to help formulate the efficient policy.

서남해에 위치한 영산강 하구는 1981년 12월에 하구언이 건설되기 전까지 전형적인 하구의 모습을 보였다. 하지만 하구언이 건설되면서 수질뿐만 아니라 식물플랑크톤이나 동물플랑크톤과 같은 부유생물들의 생물상들도 변화를 나타낼 것으로 예상된다. 따라서 기존에 보고된 자료와 최근 채집한 현장조사 자료를 토대로 식물플랑크톤 군집과 식물플랑크톤 관련 환경인자들의 변화를 조사하였다. 하구언 건설 직후(1984년)의 환경 자료와 최근 자료를 비교 검토한 결과, 담수

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.

Daily workers in construction sites rarely receive the benefit of systematic safety and health training as they are required to move from one construction site to another in response to the start, completion, and repetition of construction works. Also, small- to medium-sized construction sites often lack the capacity to train their workers. Therefore, as in the advanced countries, basic OSH training sheme for construction workers should be conducted in the industrial-level, rather than in individual workplace-level, to make the training more effective. By doing so, only workers with the basic safety training will be able to engage in construction works. Consequently, accidents in the construction industry will decrease, as workers themselves who are at the forefront of the construction worksites are empowered to play the central role in accident prevention activities.
