A competitive generating company (GENCO) could maximize its payoff by optimizing its generation assets. This paper considers the GENCO's arbitrage problem using price-based unit commitment (PBUC). The GENCO could consider arbitrage opportunities in purchases from qualifying facilities (QFs) as well as simultaneous trades with spots markets for energy, ancillary services, emission, and fuel. Given forecasted hourly market prices for each market, the GENCO's generating asset arbitrage problem is formulated as a mixed integer program (MIP) and solved by a branch-and-cut algorithm. A GENCO with 54 thermal and 12 combined-cycle units is considered for analyzing the proposed formulation. The proposed case studies illustrate the significance of simultaneous arbitrage by applying PBUC to multi-commodity markets.

Human sensibility ergonomics is the technology of measuring human sensibility, applying informaiton to the design of products, systems, and environments for convenient, comfort, and safe human use, and pleasuring human life. This study introduce the research contents and strategy on the human sensibility ergonomics project, which started as one of the national research projects of Korea. The objective of the project is to construct the basis of application technology for human-centered products and environments design in order to enhance the competitive power of the products and the quality of human life. The project consists of three main parts, that is, development of fundamental technology for human sensibility, development of simulator for measurement and evaluation of human sensibility, and development of application technology for products and environments. Total research funds is 70million dollars for 7 years.

Designers in Korea have stuck to development of furniture which has high reliance of foreign national resources. They made mistake that they didn't try to make inroads into the world market. They have kept production system of labor intensive method till 1990. They imitated foreign manufactures to win in domestic economy. It became the complete lack of exploitation experience and brought stagnation of design which couldn't defeat. Now Korea is making progressive impression in territory of an electron and information in a foreign market. A new progress of furniture design which was developed centering around a digital suggest a new appearance that will lead a future with modernization in a space of residence. This sis a new starting point which was most completed by anyone. If we will prepare without delay we can take part in a world market with competitive power.

Recently fishing industry is interested in efficiency and automation to acquire the international competitive power of national fishing industry. As an automation device of fishing boat, there are electric compasses using GPS and terrestrial magnetic sensor. Electric compass can be minimum size, high effectiveness with keeping the characteristic of a magnetic compass. This can be used a heading angle sensor to construct auto-navigation system in a small size ship. This paper develop electronic compass system that has serial output signal in NMEA 0183 and demonstrates the possibility of the electronics compass in navigation system for a small sized ship.

The Korean National Photovoltaic Project was initiated in October 1989 to develop technologies for the generation of economically competitive electric power by photovoltaic systems. It consists of four stages through the year 2006 with technical goals and cost targets related with solar cells, balance of systems and system application. The objectives of the project are to utilize photovoltaic technology, to transfer developed technology to industries and end users by research activities and to diffuse photovoltaic systems by demonstration projects. This paper reviews long-term plan abd status of technology R&D, and markets of photovoltaics. Some activities designed to promote collaboration with foreign countries are also introduced.

Changing environments in agricultural business make it necessary to promote the cooperative farming system so as to scale up farming size, which may contribute to increasing competitive power. Therefore, rural and fishery development program was established in 1990 to encourage individual farmers to jointly form the agricultural company or farming cooperatives. However, while the number of agricultural corporations has rapidly increased through the governmental support, their business achievements become worsening mainly resulting from unplanned and careless management practices. This paper suggested following strategies for management process reengineering to improve the efficiency of agricultural corporations; challenging business initiatives to enlarge volume of sales amounts, maintaining the optimal level of participants and physical assets for cost savings, and proper use of information technology and consulting agencies.
