  • 국내외 건설규모가 축소됨에 따라 건설기술인력의 신규 인력채용기피 및 수급상의 불균형 등으로 인해 대학졸업자의 취업이 극히 어려운 현상을 보이고 있다. 이러한 상황에서, 최근 대학졸업자의 취업률이 $35\%$미만으로 나타나는 등 건설기술인력의 실업대책이 중요한 사안으로 부상하였으나, 건설기술인력의 과잉문제를 해결하기 위한 범정부 차원의 종합적인 대책이 미흡하였다. 또한 대학졸업자의 교육성과에 있어서도 다양화, 첨단화되고 있는 건설산업 현장에서의 수요에도 부합되지 못하고 있다. 이에 본고에서는 $2003{\~}2008$년간의 건설기술인력의 수급예측을 하였고, 과잉공급된 건설기술인력의 수급효율화 방안을 마련하기 위해 SOC 투자확대, 미취업 건설기술인력의 IT분야 유도, 해외진출 확대 등 건설기술인력의 고용창출방안과 더불어, 건설관련 학과의 탄력적 운영, 기업수요에 대응한 대학교육 등 양적 질적인 측면을 동시에 고려한 건설기술 과잉인력의 수급대책을 마련하였다.

  • The in-core instrumentation measures core power distribution and coolant temperature in local regions of the core in pressurized water reactors. The installation types are distinguished by the designs of routing paths that exit either through reactor bottom mounted instrument nozzles or through reactor top mounted instrument nozzles. Although each type has unique advantages, it is generally known that top mounted design is more competitive with respect to emphasizing nuclear safety issues and ability to cope with severe accidents. The international nuclear vendors have provided various types of reactors with top mounted design. Nuclear power reactors in Korea, however, only have been designed to be applicable to the use of bottom mounted design, and it has been pointed out that the capabilities of Korean reactors against severe accidents should be further enhanced. The paper deals with technical issues on reactor internal and external design, in-core instrumentation, support assembly, sealing mechanism with nozzles, handling, and analytical issues in order to establish the ways of development.

  • The wind power generation is an eco-friendly clean energy that produces almost zero $CO_2$ emission, and has a good economic feasibility. As for the location, the installation of large turbines and construction of large-scale wind farm is easier on the offshore than on the land. In Korea, it is inevitable to generate offshore wind power through the offshore wind farm, and the radio interference of larger wind power generators and offshore wind power farm to broadcasting, communication and radars is becoming a core issue for constructing the offshore wind farm. In this study, the wind power generation status and rotor blade technology trend were presented, along with the technical trend of radar radio interference reduction relating to construction of the offshore wind farm.

  • 최근 전문건설업종의 대공종화/대업종화가 진행되고 있으며, 건설공사의 기술적인 전문성을 고려하지 않은 채 전문건설 업종을 편리에 따라 통합·신설하고, 고유의 업종을 폐지하는 방향으로 추진하고 있어서 건설산업 생산구조에 혼란을 초래하며, 업종 단순화만을 목표로 하여 설득력이 떨어지므로 전문건설업의 세부 공종 특성에 따라 재편 방안을 검토하는 것이 바람직하다고 판단된다. 본 연구에서는 전문공사업의 전문성에 대한 특수성을 고려한 합리적인 분류체계의 개편을 검토하기 위하여 도장공사, 조경공사의 사례를 대상으로 공사의 구분, 주요 업무내용 및 특성, 기술적 전문성, 대업종화에 대한 문제점을 분석하였다. 이를 바탕으로 현행 전문건설업 업종분류체계 개편 시 고려하여야 할 사항을 도출하고 합리적인 업종별 개편방안을 제시하고 한다.

  • 건설엔지니어링의 사업비는 공사비의 $3\~5\%$ 정도에 지나지 않으나, 최종 사업목적물의 성능을 결정하는데 커다란 영향을 미치고 있어 매우 중요하다. 그러나 그동안 정부 및 민간업체에서는 시공분야보다 건설엔지니어링분야의 기술개발투자 및 경쟁력을 강화하기 위한 대책마련이 미흡하였다. 따라서, 본 고에서는 미개척국가이면서, 시장의 잠재력이 큰 러시아, 리비아, 인도네시아를 대상으로 국내 건설엔지니어링업체의 경쟁력을 SWOT 분석법을 이용하여 비교 $\cdot$ 분석하였고, 해외출장 및 관련전문가의 면담조사로 국내업체의 해외 진출시 문제점 및 애로사항을 조사 분석하였다. 또한, 본고에서는 건설엔지니어링 업체의 기술력 향상과 대외경쟁력 저하원인을 다양한 측면으로 분석하여 해외시장으로 진출하기 위한 정부 및 민간차원의 해외진출 활성화 방안을 마련하였다. 특히, 국내업체의 해외진출 활성화 방안으로, 해외 정보 수집지원방안, 조세 및 보조금 지원방안, 타 기관과의 전략적 제휴방안 등을 제안하였다.

  • This study provides technical information about the nuclear fuel handling process, which consists of various subprocesses starting from new fuel receipt to spent fuel shipment at a nuclear power plant and the design requirements of fuel handling equipment. The fuel handling system is an integrated system of equipment, tools, and procedures that allow refueling, handling and storage of fuel assemblies, which comprise the fuel handling process. The understanding and reaffirming of detailed code requirements are requested for application to the design of the fuel handling and storage facility. We reviewed the design requirements of the fuel handling equipment for its adequate cooling, prevention of criticality, its operability and maintainability, and for the prevention of fuel damage and radiological release. Furthermore, we discussed additional technical issues related to upgrading the current code requirements based on the modification of the fuel handling equipment. The suggested information provided in this paper would be beneficial to enhance the safety and the reliability of the fuel handling equipment during the handling of new and spent fuel.

  • In this paper, we introduce prediction program of HVAC system, HJNOVAC Version 2.0. The developed program adopts both the authentic empirical method suggested by NEBB and acoustic power balancing method. The program provides intuitive pre- and post- processor using modern GUI function to help efficient modeling and evaluation of cabin and HVAC component noises. To verify the accuracy and convenience of the program, we carry out noise prediction of HVAC system for 8,100 TEU Container Carrier and measure the noise levels of cabins during sea trial.

  • Construction industry faces a lot of inherent uncertainties and issues and the construction phase of nuclear power project is not free from this risk. This paper investigates promising methodologies to be used on nuclear power plant (NPP) construction schedule delay risk assessment by using entry level systems engineering approach. This study contains how the initial concept for the risk assessment methodology has been developed. In this point of view, this work structured on three main phases: needs analysis (NA), concept exploration (CE), and concept definition (CD) through systems engineering (SE) approach. Traditionally, the SE process is applied to technical development programs but this study opens up a new avenue that SE can also be successfully applied to the development and optimization of the risk assessment model. This study provides a rational and systematic process for developing and selecting the best risk assessment model. This paper selects analytic hierarchy process (AHP) method to assess NPP construction schedule delay risk for international project. As conclusion, the proposed concept and selected method can discriminate successfully and clearly among schedule delay risk assessment methods.

  • The power plant companies reached the culmination for growth in the domestic market. Besides, we have faced many challenges such as an electricity opening market trend for overseas, banning the use of coal due to the United nations framework convention on climate change, and the meticulous attention regarding the government's electricity charge plan. On the other hand, the overseas business has been a critical issue since China and many other developing countries expanded their projects abroad. Another factor is that power plant industry is being privatized, and it made the market regulation a bit loose. Thus, the market environment became favorable toward those companies which planned many overseas businesses. In this research, the power plant company's current condition for construction and operation as well as its technical competitiveness were analyzed, and an alternative plan using SWOT analysis for entering an oversea market was made. It dealt with both internal and external factors. Also, examined was the current situation under the power plant industry dealing with restructure for electric industry, lack of fossil fuel, and the United nations framework convention on climate change. From the research, it was suggested that many successful strategies to enter the overseas business by using the market trend I researched.
