In these days, national R&D projects are taking major roles to strengthen national competitiveness. In order to produce successful R&D project, the most important point is objective and specialized evaluation. That means an appraisal board composed of experts in each field is necessary. But, it is very difficult to entrust experts, because of the constraints of time, space. In this paper, I describe the remote evaluation system for experts appointment, cost reduction and security enhancement.

Gestation duration of cow is an important economical trait. Shortening the gestation duration decreases the production cost and increases the competitiveness of Hanwoo industry. Thus, this study was carried out to analyse the effect of expected factors on gestation duration and make an alternative idea for reduced gestation duration. Gestation duration was not affected by cow-parity, but significantly affected by farm, Al year and sire. Therefore, reducing the gestation duration of Hanwoo may require both providing optimum feeding environment and nutrition management for cow and selecting optimum sire for AI.

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.

The back-to-back and box-shaped headers used in light gauge steel structures have some disadvantages, i.e., construction efficiency and cost competitiveness. As such, cold-formed steel L-shaped headers have been developed and are used actively in advanced nations. However, this system has not been used in Korea because of inadequate investigation and adaptation efforts and lack of application example. Thus, this research evaluated the structural performance of L-header using buckling analyses and bending tests. Test results were compared using the AISI design criteria. Test results showed that local buckling and distortional buckling governed buckling behavior in gravity loads and uplift loads, respectively. These results were consistent with the calculated nomial strengths using the AISI design criteria.

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
