National technical qualification testing system of the technical high school and the technical college graduates has been carried out since 1975 in Korea. This enforced system was served as the betterment of actual training and the extension of the workshop equipment in the technical high school and the technical college. But this system gave rise to the difficulties of regular management of the technical high school and college education, for it cause the neglect of the normal curriculum management in the excess of concentrating on skill practice. In order to study the effective management of national technical qualification testing system, We have analyzed the reason through many questionaires to technical college proffessor, and technical high school teacher, technical manager, technican and engineers in industry. The general plans studied for the effective management of national technical qualification testing system are as follows, 1) National technical qualification testing system should be analyzed relating duty of industrial society to do official endorsement. 2) National technical qualification testing system should be conduct by the industrial organization such as the Gild Association in United Kingdom. 3) National technical qualfication testing system should be consist of industrial construction analyzing committee.

홍원표(Won-Pyo Hong) 한국조명·전기설비학회 2004 한국조명·전기설비학회 학술대회논문집 Vol.2004 No.5월
In this paper, a new distributed intelligent control module based on LonWorks fieldbus for air handling unit(AHU) of heating, ventilating and air-conditioning(HVAC) is proposed to replace with a conventional direct digital control(DDC) with 32 bit microprocessor. This article also addresses an Internet- based HVAC system architecture that combines Web technology and networking. The proposed control architecture has a excellent features such as highly compact and flexible function design, a low priced smart front-end and reliable performance with various functions. This also addresses issues in control network configuration, logical design of field devices by S/W tool, Internet networking and electronic element installation. Experimental results showing the system performance are also included in this paper.
