The existent cutting insert have occupied most product of grinding style, because it has a problem of accuracy and manufacturing process. The product has a concept but development is difficult, because grinding and manufacturing by press are impossible. But by development and stabilization of a technology, preference of non-ground insert increases gradually. And then insert that grinding is impossible is developed availably as non-ground product by using developed equipment and software. In this paper reports some experimental results on the machining performance of non-ground Cutting inserts. Three kinds of Cutting inserts were manufactured without using grinding process. Machining experiments were carried out to compare the machining performance of non-ground inserts with that of ground ones. The experimental results indicate that the cutting forces and tool wear and surface roughnesses of machined surface of both ground and non-ground inserts are comparable.

벤처기업이 성공하기 위해 가장 중요한 요소인 기업가정신이 기술상업화 과정에서 연구개발 자원, 기술혁신, 그리고 기술이 어떻게 작용하는지를 살펴보기 위하여 제조업분야 벤처기업을 대상으로 설문조사를 실시하였다. 구조방정식모형을 분석함으로서 기업가정신이 기술상업화를 이루는 메카니즘이 규명되었다. 기업가정신 중에서 혁신성이 가장 중요한 요인이었고, 기술상업화는 연구개발 자원보다는 기술혁신에 의해서 크게 영향을 받았다. 기술혁신이 상업화에 매개역할을 하고 있지만 연구개발 자원과 기술역량은 상업화에 매개 역할이 되지 못하였다. 제품개선에 의한 매출 신장과 신제품 개발에 의한 매출 신장의 기술상업화 과정은 서로 다른 양상을 보였다. 정부는 벤처기업의 기업가정신 함양에 의한 혁신 촉진과 연구개발 인력뿐만 아니라 벤처기업의 상업화 제고를 위해서는 연구개발 전략과 상업화 인프라 조성에 대한 적극적인 지원과 연구가 필요하다.

This study evaluates the economic impact of product innovation by using firm-level data from the Community Innovation Survey conducted in Japan. It accounts for possible technological spillover from innovation activities and examines the extent to which new-to-market product innovations contribute to firm performance. Econometric analysis using a simultaneous equation model reveals that new-to-market product innovation is likely to increase a firm's sales without cannibalizing those of existing products and generate more technological spillover to other firms. Moreover, such innovation is more likely to emerge from firms collaborating with academic institutions. The paper concludes by discussing policy implications of these findings as well as points to the importance of cross-country comparison between Korea and Japan.

This paper investigates the design of a priority rule in a multi-product disassembly environment. Specifically, it is concerned with product scheduling by which the inventory control of disassembled parts can be incorporated into a priority rule to reduce part lead times. The part lead time consists of two components: flow time and supply delay. The primary focus of the paper is on the development of a disassembly priority rule that aims to reduce the supply delay. We propose a priority rule, called Minimum Distance (MD) rule, to improve the supply delay performance. Finally, we provide a comparative analysis on the performance of traditional rules and the new rule proposed in this paper via a simulation model.

During the past decade, functional foods and nutraceuticals have emerged as a major consumer-driven trend, serving the desire of aging populations to exercise greater control over health, delaying aging, prevent disease and enhance well-being and performance. On a global basis, retail sales of functional food were worth an estimated USD 1,501 billion in 2001. The market for functional food in Korea has increased in the last three years above 10%. Especially value sales rose by over 30% between 1999 and 2001, and are worth around 12,000 billion won in 2001. To regulate functional food represented a rapidly growing market in Korea a new act 'Functional Health Food Act' was announced officially in 2002. The type of functional milk product in Korea market is conventional food containing various functional ingredient. To promote functional food market in milk product sector the introduction of functional and health claim should be taken into account in the future in Korea.

It is anticipated that quality assurance for the Ka band Communication Payload System(COPS) development program of the communication, Ocean & Meteorological Satellite(COMS) may be a core technical factor to be concerned in order to avoid any failure, and to assure its final performance during the mission lifetime in space. Those can be managed and verified and assessed by performing the Quality Assurance (QA) and risk management which helps to prevent and to reduce the critical fails. This paper introduces the Product Assurance (PA) system and procedures for controlling and monitoring sub-contractors which were participated in Ka band Communication Payload System (COPS) development. Also this paper shows Quality Assurance (QA) procedures and detailed their processes for assured the product performed by local companies from site survey for selecting companies to delivery of their equipment.

본 논문에서는 한국 제조기업들을 대상으로 역동적인 환경 하에 공급사와 구매사의 신제품 개발 기술협력이 구매기업의 신제품 개발 프로젝트의 운영성과에 미치는 영향에 관하여 고찰하였다. 한국생산성본부와 지식경제부가 공동으로 조사한 2012년도 한국 600개 제조기업 조사 자료를 기반으로 회귀분석 방법을 사용하여 분석하였다. 독립 변수로 구매사와 구매사의 주요공급사와의 신제품 개발에서의 기술협력을 사용하였고 종속변수로 구매사의 신제품 개발 프로젝트의 품질달성률(quality), 비용절감(cost), 개발일정준수률(time)의 세 가지 운영 성과를 사용하였다. 환경의 역동성을 조절 변수로 사용하였다. 실증분석 결과 공급사와 구매사간의 기술협력이 신제품 개발 프로젝트 품질 달성율 제고에 긍정적인 영향을 주는 것으로 나타났다. 그러나 예상과 달리 환경의 역동성은 오히려 공급사 구매사의 기술협력의 신제품개발 프로젝트 성과에 모두 부정적으로 작용하는 것으로 나타났다. 이에 환경의 역동성이 높은 산업(통신기기산업)과 낮은 산업(조선산업)으로 분리하여 사후분석을 실시하였다. 사후분석결과, 역동성이 낮은 산업에서는 구매사-공급사의 기술협력이 신제품 개발 프로젝트 운영성과에 긍정적인 작용을 하지만 역동성이 높은 산업에서는 구매사-공급사의 기술협력이 구매사의 신제품 개발 프로젝트의 운영성과에 부정적인 영향을 주고 있음을 발견하였다. 역동성이 높은 산업은 새로운 기술이 요구되는 경우가 많아 기존에 지속적으로 거래를 하고 있는 특정 공급업체와의 협력을 통한 축적된 학습효과 및 시너지를 누리기가 어렵고 이에 주공급업체와의 협력이 프로젝트 운영의 효율성으로 연결되지 못하는 것으로 보인다. 반면에 환경의 역동성이 낮은 환경에서는 기존의 공급업체와의 협력을 통한 축적된 협력 역량 프로젝트 운영성과 향상에 긍정적으로 작용하는 것으로 보인다. 이는 신제품 개발 프로젝트의 속성과 횟수는 기업이 처한 환경과 밀접히 관련되어 있고 주 공급업체와의 기술 협력의 효과는 환경에 따라 다르게 나타나고 있음을 시사한다.

High-tech industry has been the principal economic source for Taiwan in recent years. The characteristics of high-tech industries in Taiwan are changeable product markets, short product life cycles and high company attrition rate. In the globalization trend, the high-tech industry has gradually increased corporate competitiveness and reached the goal of sustainable operations through knowledge management, knowledge sharing and new product research and development. Firms have aggressively strengthened and integrated their internal and external resources and enhanced knowledge sharing to increase industry operational performance. Effectively strengthening the knowledge management operation and performance evaluation of knowledge sharing in Taiwan's high-tech industry has become a critical issue. In the selection of knowledge sharing Key Performance Indicators (KPI), this research divided the knowledge sharing indicators into representative strategic indicators such as organizational knowledge learning, organizational knowledge resources, organizational information capacity and organizational knowledge performance through screening using Factor Analysis. The characteristics of the constructs were interdependent. This research calculated and adjusted the correlation among the key performance knowledge sharing indicators using ANP and determined the relative weight of knowledge sharing.
