  • R&D사업의 성공적인 성과 창출을 위해 무엇보다 중요한 요소는 과제의 객관적, 전문적 평가이다. 이를 위해서는 각 분야의 전문가를 평가위원으로 위촉함으로써 평가의 객관성, 전문성을 높이는 것이 중요하다. 그러나, 평가위원 위촉시 시간적 여건이나 대면평가로 인한 지리적 여건 등으로 전문가 위촉에 어려움 발생하는 것이 사실이다. 본 논문은 우수한 평가위원 위촉과 평가에 소요되는 비용을 절감할 수 있는 원격지 전자평가 환경 구축에 대해 논의한다.

  • 오늘날 정보화 사회에서 경쟁하는 기업들에 있어서 데이터품질 저하는 기업경쟁력 하락과 새로운 비용창출이라는 부정적인 영향요인으로써 작용하고 있다. 이러한 데이터품질 저하의 문제를 해결하기 위해 데이터품질에 대한 많은 선행연구들이 진행되어 왔으며, 데이터품질의 측면 중 결과적 이고 현상적인 품질개념인 데이터 값의 품질과 데이터서비스의 품질에 대해 주로 연구되어 왔다. 이에 반해 본 연구에서는 원인적인 데이터품질 개념인 데이터의 구조적 품질을 메타데이터 관리의 관점에서 연구하였으며, 이를 통해 평가와 개선을 위한 관리의 관점이 적용된 데이터품질관리 성숙도모델을 제시하였다. 또한 본 연구에서 제시한 데이터품질관리 성숙도모델의 타당성 검증을 위해 데이터품질 관리단계가 성숙될수록 데이터품질수준이 높아지게 된다는 것을 실증적으로 검증하였다.

  • 임신기간은 주요 경제형질 중 하나로서, 임신기간의 단축은 생산비를 감소시켜 한우산업의 경쟁력을 재고시킬 수 있다. 따라서 본 연구는 임신기간에 영향을 미칠 것으로 예상되는 요인들의 효과를 분석하고 대안을 제시하기 위하여 실시하였다. 빈우의 임신기간은 빈우의 산차에 의해 영향을 받지 않았으나, 사육농가와 수정년도 및 종모우에 따라 유의한 차이가 있었다 따라서 임신기간을 단축시키기 위해서는 빈우의 사양환경을 최적화하고 영양관리를 적정화하며 적절한 종모우를 선택하여 인공수정에 사용하여야 한다.

  • The construction market became generally opened to overseas and the domestic construction industry has competed with the international construction enterprise of which technical knowledge is superior. In order to compete with the international construction companies, domestic construction industry needs more continuous promotions on the research and development for improving the level of technique of the construction engineering to meet the international norm. This study aims to suggest the better standards of engineering output such as drawings and specifications to correspond the changing integration system and bidding system in preparation for growing international competition. The study starts with comparison and analyses of domestic and international methods and standards for preparing design drawings. And it continues to delve into actual drawing preparation practices, especially focusing on the ones for road and subway construction. Finally, the study presents a better way of the standardization of the main drawings such as general plan, longitudinal drawing, cross section, structural drawings and temporary structure for new bidding systems of historical cost estimation and whole specification tender and for promotion of international competitiveness.

  • To ensure competitiveness in the modem automotive market, process and material planning should be performed concurrently with new car developments. In automotive general assembly shops, thus, new business workflows and supporting environments are inevitable to reduce the manufacturing preparation time in developing a new car in the manner of concurrent and collaborative engineering. Since complete material planning for a whole general assembly system is a huge and complex job, several planners should execute their planning jobs and share information. Therefore, each planner should provide others with his/her results with continuous on-line communication and cooperation. In this research, a web-based system for concurrent and collaborative process and material planning for automotive general assembly via 3D digital mock-up S/W is developed. By using this system, savings in time and cost of process and material planning are possible, and the reliability of the planning result is improved.

  • 스틸 스터드 구조물에서 사용되고 있는 기존 I형, 박스형 헤더는 시공성, 경제성 측면에서 여러 가지 문제점을 노출하고 있다. 이러한 문제점을 극복하기 위해 선진국에서는 냉간성형강을 L형으로 절곡한 L-헤더를 활발히 사용하고 있다. 그러나 국내에서는 이에 대한 연구가 부족하여 L-헤더를 사용하지 못하고 있는 실정이다. 본 연구에서는 이러한 문제점을 해결하기 위해 L-헤더에 대한 좌굴해석 및 휨 실험을 수행하였으며, 실험결과를 미국 철강협회(AISI, American Iron and Steel Institute) 설계기준과 비교하였다. 휨 실험결과 중력방향 하중이 작용하는 경우에는 국부좌굴이, 인발하중이 작용하는 경우에는 뒤틀림 좌굴이 발생되는 것으로 관찰되었다. 그리고 실험에서 측정된 좌굴 하중을 비교한 결과 AISI 설계기준에 제시된 공칭하중을 상회하는 것으로 확인되었다.

  • Supply Chain Management(SCM) system is a critical investment that can affect future competitiveness and performance of a company. When adopting a new SCM system, organizations experience increasing difficulty in decision making because information technology is changing so rapidly these days. Therefore, organizations have been looking for industry standards and proven methods of selection that they can utilize to choose the best SCM system. To select an optimum solution, we need to consider a number of different quantitative and qualitative factors such as cost, user interface and convenience, reference site, and so on. In this study, we propose a solution selection model of SCM systems using Fuzzy AHP to maximize the return on investment in information technology. The proposed model can systematically construct the objectives of SCM system selection to support the business goals.

  • It has shown that the investment on the new products have a direct influence on the price of manufactured goods. This brings about a point, which has been a common problem for many Korean enterprises. That is Korean products can only its international competitiveness from the price, not quality. Our industry has shown its movement from producing cheap, low quality products to creating somewhat more advanced and higher qualify products. However the industry cannot avoid the financial burden from the investment. Just like the title of this article, for existing the 3D-MODELING, the 3D-CAD is existed first has immediate effect on the many developing processes, such as planning a product, designing, and producing. The development of the furniture design in the future will be done in the same way as this article presents. This will have a great effect on the overall productivity. (Time, cost, efficiency and etc). The simulation experiment on this article is based on the idea of development of industry, forms the immediate constituent for the prediction related to the production development, marketing and the trend. Which means, this will play an important part where companies achieve satisfaction from the marketing part and the economy.

  • The simplification of solar thermal systems reduces the possibility of operating trouble and lowers the cost of the initial investment and maintenance. This also leads to increased competitiveness in the energy market. We proposed a spiral-jacketed storage tank that functions both as a heat exchanger and expansion tank, which removes the secondary piping and markedly simplifies the entire system. The new storage tank was designed and manufactured to maintain the same performance as the conventional system and the exiting system was remodelled by adopting the newly proposed storage tank. This experiment was conducted under real conditions over a period of several months. The retrofitted system with the spiral-jacketed storage tank showed good performance that is on a similar level as the previous system having a typical storage tank and heat exchanger.

  • Trade between Korea and China was 372million dollars accounting for 1.56% of total in 1988 and has been increased to 23,689 million dollars occupying 7% in 1997, which implies 32.2% increase on average per year. This trend will continue dramatically and consistently as China's open policy toward the world accelerates and korean companies advance into chinese market. The main trade routes are with marine transportation between korean west sea area and chinese San-Dong peninsula around east sea. However, due to the increasing traffic congestion on main roads connecting harbors and main consumer cities and capacity problem in west sea harbor areas, the logistics cost have been increased resulting in losing competitiveness of freight trade. Therefore, these road-oriented inland transportation means need to be changed to rail transport system to reduce congestion and to conserve natural environment. To achieve this scheme, efficient intermodal transportation system connecting road and rail should be constructed. These combined system will ensure timely delivery of goods and consequently the customers would make proper transportation schedule for the import/export goods in advance. Especially, combined transportation of Railroad and train ferry would cope with the logistics problem and this system would be efficient means for trade with not only China but further with many adjacent countries in central asia such as Kazakhstan and Uzbekistan
