Recently, due to construction of the recession quantity of unsold houses is increasing and construction company is experiencing financial difficulties. As a result, construction is being ousted, or workout. Accordingly, construction may be devising a method for oneself like salary cuts, layoffs as part of the rationalization of management. But in this way may be increasing employees's perception about job insecurity and payment unsatisfaction. This has the potential to do employees turnover. Turnover has be known that it brings both positive and negative results to the organization. But if new employees leaves early, the positive aspect of the organization will be less likely. In order to solve these problems, new employees turnover intention will be necessary for the thorough management. The purpose of this study is to identity how the perception of job insecurity, payment satisfaction, organizational commitment, excessive workload, competitiveness for employment and job suitability affect new employees turnover intention. As the degrees of impacts of variables affecting turnover intention of new employees might be different between small to medium and large construction companies, this research also compares the differences between these two groups and suggest measures for reducing turnover intention.

Owing to diversification of social desire and increase of demand as economic growth, construction industry recently is trending toward diversification, complication, gigantism. It means that is changing to difficult environment as existing construction company operation. Specially, some big construction companies are promoting get down to construction business risk management skill & development. Enterprise risk management system, recognized to risk portfolio, is suggested. instead of individually risk management. This study indicates ERM basic model, considering construction risk character, for apply to ERM to field of construction . And it is including analysis of recognition level and reality about ERM in construction company.

Recently, a few major construction companies in Korea have a growing interests to the risk management system, and they are trying to apply it to their construction projects. However, the existing methodologies to be applied to the foreign public projects are not proper to the construction environments due to its adaptabilities, that has one time process and heavily depends on personal judgement. The purpose of this paper is to propose a risk response process in consideration of the residual risks, which would be more adaptable and practical in the construction environment, overcoming the current obstacles to be mentioned above. This process has systematic repeat process until the residual risks go down to the risk thresholds based on the efficiency of specific response strategy.

Recently many Korean large-sized construction companies as well as specialty contractors have been expanding their business in the overseas market to mitigate impacts from long-term stagnation in the domestic market. Such as a result, it has been arisen as a major issue that contractors effectively manage the delays which have been commonly faced with in international mega-projects. Therefore it can be said that the ability of the delays management leads a success of project. This paper presents a review of literature for delay analysis methods such as time impact analysis(TIA) and raises practical problems to rationally substantiate the duration of extension of time(EoT) in international mega projects which have wide scope of works as well as complicated and detailed contract baseline programs by taking theoretical approaches. We suggest the two improvement concepts to substantiate the EoT claims which are effectively applicable to practical projects. The first is to sort out dominant delays among numerous delays in advance of applying a delay analysis. The second is to set up the delay sections with the advanced concept for analysing delays' effects by TIA. This study performed a case study on an actual international mega-project. to confirm the effectiveness of improvement concepts that this practical approach is applicable for the assessment of EoT. In conclusion, this paper supposes to provide practitioner in charge for an EoT claim with an advanced substantiation methodogy when they not only analyse the construction delays by using TIA, but also negotiate with stakeholders about with the assessment of EoT.

풍력발전기는 2000년대 초반에 발전기 회전자 직경이 80m에 이르는 2MW급 풍력발전기들이 여러 회사에서 개발되면서 경제성 및 신뢰성도 향상되어 비약적인 발전을 이루게 되었다. 풍력발전시장의 신규발주와 설치장소가 한계점에 이르게 됨으로써 경제성이 뛰어난 대형 풍력발전기의 필요성이 대두되고 있다. 이와 같이 풍력발전기의 대형화 추세는 대형화를 통해 에너지 효율의 증대뿐만 아니라 단위 용량 당 건설비 및 설비비 절감이 가능하기 때문에 풍력발전기 대형화를 위한 기술개발이 활발히 진행되고 있다. 하지만 현재 풍력발전기에 사용되는 기계적 기어박스는 윤활유 주입 및 보수 점검의 문제점이나 소음, 진동, 마찰에 의한 열 발생 등의 문제점들을 가지고 있다. 이러한 문제점을 해결하기 위하여 기계적 기어박스를 마그네틱 기어를 이용하여 구성하고자 한다. 따라서 본 논문에서는 마그네틱 기어를 이용하여 10MW급 풍력발전기의 기어박스를 설계하고 그 가능성을 검토하고자 한다.

Information trend in whole domestic industries can not be a exception for construction industry either. However, Construction companies applying quality information management system(QIMS) through practical use of internet is very limited. Consequently, this research finds the established sample of quality information management system(QIMS) of H-construction company out, and the quality is established to the practical use of the system to be like the this. therefore, the construction industry wished to become opportunity that construction industry competitive power is recognized cosmopolitanly to quality management system(QMS).

It is related to launch the CM market and to increase the profit and entire ability in company that is enforcing the ability of construction management in large-scaled construction company. According to the CM market in U.S, CM market is increased with competing to the companies, that is E&C, general contractor, design firm, specialized CM firm. Also domestic market is similar to US market. In this situation, large-scaled construction companies are filled with construction management ability for competing with foreign companies and domestic CM firms. This paper suggests how to enforce the construction management ability through education, and shows the detailed education strategy considered the fields, divisions and positions.

교량공사에는 여러 가지 기초공사 방식이 적용될 수 있다. 국내에서는 특히, 한강을 통과하는 교량에는 거의 대부분 우물통 기초를 채택 시공하고 있다. 이들 교량공사들이 진행되는 과정에서 계속 사상자들이 발생해왔다. 2001년 현재 서울시 건설안전 관리본부 자료에서는 1995년부터 총 00명을 기록하고 있는 것으로 나타났다. 서울시 건설안전관리본부, 각 유명 대형 건설사들의 건설안전팀들이 부단히 노력하고 있음에도 계속 발생되는 것은 어디에 있는가？ 하나로 확정지어 답해질 수는 없는 특성이 있다. 건설회사 조직구성, 작업인력구성, 공정, 장비구성들이 관련 사항들일 수도 있지만 안전교육 또한 영향을 미치는 핵심요소라 할 수 있기 때문에 이 안전교육의 유효성 효율성에 관한 정확한 측정은 사고예방 그리고 년간 교육계획 등 사전계획에도 큰 영향을 주는 요소일 수 있다.(중략)

국내외적으로 풍력발전 시장이 크게 확대될 것으로 전망되고 있다. 특히 올해 도입예정인 신재생에너지 공급의무화(RPS)와 관련해 풍력산업이 가장 큰 수혜를 볼 것으로 예상되고 있다. 정부는 '신재생에너지 개발 이용 보급 촉진법 일부 개정 법률안'에 따라 2012년 총 전력공급량의 3%, 2020년 10%를 RPS비율로 예정해 놓은 상태이다. 풍력, 태양광 등 신재생에너지의 발전 단지 건설이 최소 2년 이상 소요되는 것을 감안하면 늦어도 2010년부터는 한전을 비롯한 발전사업자들의 신재생에너지 발전 단지 발주가 급증할 것으로 예상된다. 설비건설업계도 풍력발전 시장에서 제2의 도약을 기대해 볼 수 있을 것이다. 풍력발전 시공기술을 확보하는 한편 최근 풍력발전 시장에 뛰어드는 대기업과 풍력발전 설계 시공경험이 있는 대형 건설사 및 엔지니어링회사와 제휴해 해외에 진출하는 방안도 모색할 필요가 있을 것이다. 이번 호에는 풍력발전 기술과 풍력발전단지 건설사례를 소개한다.
