In this study, we establish technology classification system for twelve material and component(MC) areas to sup-port systematic information services for MCT-20l0 which is supported by Korean government. We propose some design principles for MC technology classification system. The principles are suggested by considering of the characteristics of MC classification, regarding with scope, originality, hierarchy, relationship between technology classification and product classification, duplication and complex structure, use of information system, and life cycle of the classification system.

본 연구는 OLED 조명산업을 대상으로 직관적 방법론을 이용한 R&D 유망 분야 발굴 연구를 수행했다. 이를 위해 국내 조명산업 전문가 69명을 패널로 구성하여 1개월에 걸친 심층면접 및 설문조사를 진행하였다. 본 연구는 OLED 조명산업을 패널, 패널용 소재/부품, 제조장비, 조명시스템의 4개 분야로 대분류하고, 각 분야별로 핵심기술을 선정하여 총 14개의 R&D 가능분야를 세분류했다. 각 분야별 기술경쟁력을 평가한 결과, 우리나라의 기술경쟁력이 가장 높게 평가된 분야는 OLED 패널 분야로 나타났으며, 반면에 OLED 패널용 소재/부품의 기술경쟁력이 낮은 것으로 평가되어 개선책이 요구된다. 한편, 경제성, 정책부합성, R&D 효과성을 종합적으로 평가하여 7개 R&D 유망 분야를 선정했다. OLED 패널의 4가지 핵심기술인 백색, 투명, 색가변, 플렉시블 OLED 패널 제조 기술이 가장 유망한 분야로 평가되었고, 다음으로 면광원용 유기소재, 기판 소재/부품, 대면적 기판형성 장비가 유망 분야로 평가되었다.

In recent years, the metal industry has become increasingly aware of an unwanted component in metal scrap-radioactive material. Worldwide, there have 38 instances where radioactive sources were unintentionally smelted in the course of recycling metal scrap. In some cases contaminated metal consumer products were distributed internationally. U.S. mill that have smelted a radioactive source face costs resulting from decontamination, waste disposal, and lost profits that range from 7 to 23 million U.S. dollars for each case. Despite radiation monitoring system does not provide 100% protection, POSCO has developed the system for the first time in the steel industry of KOREA.

Recently, the FPD industry has faced the limit in market growth due to lack of new growth engine as a replacement of television. With sluggish market demand deepened by global economic crisis and persistent concern over panel oversupply, growth of the panel market has sharply slowed down, and profitability has been eroded. This also has tremendous effect on related industries including component, material and machine industries, spreading a sense of crisis across the whole FPD industry. Under this circumstance, for the FPD industry to take off once again, all involved in the FPD industry must cooperate and come up with innovative ideas, and identify the driving force to realize turbo-charged growth.

Detection of specific compounds influencing food flavor quality is not easy. Electronic nose, comprised of electronic chemical sensors with partial specificity and appropriate pattern recognition system, is capable of recognizing simple and complex volatiles. It provides fast analysis with simple and straightforward results and is best suited for quality control and process monitoring of flavor in food industry. This review examines application of electronic nose in food analysis with brief explanation of its principle. Characteristics of different sensors and sensor drift. and solutions to related problems are reviewed. Applications of electronic nose in food industry include monitoring of fermentation process and lipid oxidation, prediction of shelf life, identification of irradiated volatile compounds, discrimination of food material origin, and quality control of food and processing by principal component analysis and neural network analysis. Electronic nose could be useful for quality control in food industry when correlating analytical instrumental data with sensory evaluation results.

현재 저작권과 온라인 디지털 콘텐츠 산업발전법은 데이터베이스와 디지털 콘텐츠 제작자를 보호대상으로 하고 있다. 미국 데이터베이스 보고서의 추가 보호론에 데이터베이스는 경제 및 과학에 있어 그 중요성을 더해 가고 있으며, 인터넷 상의 핵심적 요소가 되어가고 있다. 그러므로 우리나라의 공공 민간 모두 데이터베이스의 법적 보호에 신중을 기해야 한다. 본 고에서는 과학기술 데이터베이스 법적 보호의 전반적인 문제점들과 현행법에 의한 과학기술 데이터베이스 보호의 핵심적인 내용과 추가적인 보호 문제를 깊이있게 다루었다. 과학기술 데이터베이스 산업의 발전이 국가의 경쟁력 확보에 중대한 몫을 차지하고 있다는 점을 고려할 때, 데이터베이스의 법적보호방안 마련은 데이터베이스의 지속적인 발전을 도모하기 위한 정책의 하나로서, 간과되어서는 안 될 중요한 사안 중의 하나이다.

We analyze competitiveness of material and component industry(MCI) of Korea, China and Japan using trade data, OECD ITCS database with HS-code system. We use unit price indices, export unit price index, import unit price index, and TOT unit price index. These indices provide quality information from trade data of value and quantity. Our results show that there are quality gaps among three countries, and that China expand development potential, and the results vary as sectors. It implies that R&D investment to improve quality of MCI products is essential and that sector-specific policy is necessary.

As the European Community's Directive on the Restriction of Hazardous Substances in Electrical and Electronic Equipment banning lead (Pb) in electronics products will take effect on July 1, 2006, most electronics manufacturers will be commencing with volume production of Pb-free components by the middle of 2004. Electrodeposited pure tin finishes on electronic components are a leading contender to replace the industry standard tin-lead. Commensurate with this shift will be a somewhat steep learning curve as manufacturers adapt a variety of equipment and processes to contend with the issues surrounding this critical, industry-wide material conversion. Since the electrodeposited finish directly influences the critical reliability characteristics of the component itself, the nature of the Pb-free component finish must be well characterized and understood. Only through a thorough examination of the attributes of the electroplated tin deposit can critical decisions be made regarding component finish reliability. This paper investigates the properties of electrodeposited tin that may have an effect on component reliability, namely, grain structure (size and shape), oxide formation, tin whisker formation, and solderability. Data will be presented from laboratory and production settings, with the objective being to enable manufacturers to draw their own conclusions regarding previously established perceptions and misconceptions about electrodeposited tin properties.

For the effective utilization of tuna processing byproducts such as roes of skipjack tuna (Katsuwonus pelamis) and yellowfin tuna (Thunnus albacores) as a food resource, the roes of skipjack and yellowfin tuna were examined on food component characteristics and also compared to those of Alaska pollack (Theragra chalcogramma). The concentrations of heavy metal in both roe of the skipjack and yellowfin tuna were below the reported safety limits, therefore, these roes appeared to be safe as a raw material for food resource. The contents of crude protein were 21.4% in the skipjack tuna roe and 21.5% in the yellow fin tuna roe, which showed to be the major component in tuna roes. The prominent amino acids of total amino acids were aspartic acid, glutamic acid, leucine and lysine, and these amino acids were comprise to be 38.4-41.2% of total amino acid in both tuna roes. The total lipid content were 2.1 % in the skipjack tuna roe and 2.0% in the yellofin tuna roe. The major component of total lipid was found to be triglyceride in both tuna roes (skipjack tuna roe, 93.3%; yellow fin tuna roe, 92.0%), which was high in the compositions of 16:0, l8:1n-9, and 22:6n-3. The content of DHA in total lipid of the tuna roes (skipjack tuna roe, 29.9%; yellowfin tuna roe, 36.3%) were higher than that of Alaska pollack roe (18.1%). Based on the results of the proximate composition, mineral, amino acid and lipid characteristic, roes of skipjack tuna and yellowfin tuna showed potential as a raw material for food.
