This paper reports an empirical study on assessment of R&D best practices. The principles of quality management and their tools such as best practices or benchmarking have been so prevailing in the operational process that the R&D management recently consider extensive use of them for their innovation process. However, characteristics of the two processes may be different each other. Are the principles or the tools that were effective in the operational field still going to be effective in the innovative field? In order to answer the question, we statistically examine how R&D best practices contribute to the innovative performance. Upon literature review on technological innovation, we present a R&D process model whereby we set forth research hypotheses. Using data from 66 successful R&D efforts carried out among Korean firms mostly between 1999-2001, regression analyses reveal that best practices used in most stages throughout the R&D process are found not to significantly contribute to the innovative performance. Only those in technology strategy and prototyping stages are proven effective for technical and commercial performance respectively. Interestingly, efforts in a problem solving and improvement stage are counterproductive in the case of the innovation process. Discussions on our empirical observations are presented followed by some managerial implications.

The laser/arc hybrid welding process is a new process combining the laser beam and the arc as welding heat source. The laser beam and arc influence and assist one another. By application of hybrid welding, synergistic effects are achievable, and disadvantage of the respective processes can be compensated. The laser-arc hybrid welding process has good potential to extend the field of applications of laser technology, and provide significant improvements in weld quality and process efficiency in manufacturing applications. This review analyses the recent advances in the fundamental understanding of hybrid welding processes using the works of the data base of Web of Science (SCI-Expanded) since the 2000 year. The research activity on the hybrid welding has been become more actively since 2006, especially in China, presenting the most research papers in the world. Since the hybrid welding process was adopted in manufacturing of the automobile in Europe in the early of 2000's, its adopting is widely expanded in the field of manufacturing of automobile, ship building, steel construction and the other various industry. The hybrid welding process is expected to advance toward higher productivity, higher precision, higher reliability through the mixing of high power and flexible fiber laser or disk laser and digitalized pulsed arc source.

인터넷 활용 범위의 폭발적인 증가는 점차적으로 네트워크 속도와 용량을 초고속화 하고 대용량화로 빠르게 진화해 가고 있다. 이에 따라 스위치 라우터 등 네트워크 장비들은 하드웨어에 기반 한 빠른 기술 진화로 대처를 하고 있으나 초연결사회에 가장 기본적이고 필수적인 네트워크 보안시스템의 기술 진화는 수만 가지의 보안 이슈와 시그니처(signature)에 대해서 수시 변경과 갱신을 필요로 하기 때문에 소프트웨어에 기반 한 기술적인 한계를 극복하기가 쉽지 않다. 본 논문은 이와 같은 DDoS 대응 장비를 설치 운영할 때의 패킷 필터링 속도 저하 문제점을 개선하고자 FPGA(Field Programmable Gate Array)의 하드웨어적인 특성과 병렬처리 특성을 최대한 반영한 DPI 알고리즘인 Hi-DPI를 제안하고 실용성을 검증하고자 한다.

This paper aims to develop a conceptual framework for determinants of spillover effects of FDI on technology innovation of Vietnamese enterprises. The research proposes a logistic regression model for assessing how enterprises' ability to implement technological innovation is affected by the presence of FDI enterprises as well as other factors that show the change through the indirect influence of FDI such as the size of the enterprise, the type of enterprise, and the skill level of the labor force or its research and development activities. Five forms of technology innovation are considered: improving production process; product quality improvement; product expansion; expanding business activities into a new field of production; and changing business activities into a new field of production. General Statistics Office of Vietnam provided survey data to collect information from 3,166 enterprises in the manufacturing and processing industry in Hanoi, which were valid for analysis. The results show that all variables of enterprise type, size, R&D, and industry have a positive impact on the selection of one of the innovation forms. Several recommendations are further suggested to take advantage of the positive effects and minimizing the negative effects of FDI for technological innovation of Vietnamese enterprises.

본 연구는 사이버교육의 활성화와 발전을 근본적인 목적으로 하면서, 원격대학을 중심으로 콘텐츠를 상호 교환하여 활용할 수 있는 체제 및 방법으로 기술 표준화를 제안하고자 하였다. 원격대학의 콘텐츠 교류를 위한 기술 표준화의 모색은 비단 원격대학에만 한정되는 문제는 아니다. 그것은 사이버교육을 수행하고 있고, 다양한 콘텐츠를 개발하여 관리를 해야 하는 주체라면 동일한 문제에 봉착하고, 기술 표준화에 대해 인식을 같이하리라 예상되기 때문이다. 이를 위해 본 연구에서는 원격대학이 당면하고 있는 콘텐츠의 공동활용 방안을 모색하고, 이미 진행되고 있는 콘텐츠의 개발 관리 측면에서 효율성을 기하는 방안을 제시하였다.

The paper evaluates the Korean science, technology, and innovation policy(STIP) in terms of an individual firm. The firm is Viromed(Ltd), a new technology-based venture company in the field of biotechnology. The case is compared with the 'Hwang Project', which is known as a typical failure case in Korea. In order to evaluate the Korean STIP, we establish 6 areas, which are technological infrastructure, institutional infrastructure, human capital infrastructure, technology market, industrial base, and innovation networks. The study shows that the policy schemes relating with technological infrastructure, institutional infrastructure, human capital infrastructure, and industrial base play a positive role in the start-up, development and innovation of Viromed(Ltd). However, we can hardly find the role of Korean government in fostering the technology market, transferring the technological output to economic performance. Although the international networks with the British, American, and Japanese firms or investors were a key success factor of the growth of Viromed(Ltd), the role of the government in this policy area was not enough. As for the 'Hwang Project', we suggest that the government should consider the possibility of commercialization in choosing R&D projects and determining the size of financial aids. Since the evaluation of the Korean STIP is based on an individual firm, the results of the paper need to be confirmed by a systematic comparison with other cases or industries.

Objectives: The liver fibroscan has been developed as a noninvasive and convenient method to assess hepatic fibrosis. This study aimed to review this device in terms of its technological concept and clinical application in traditional Korean medicine (TKM). Methods: The technological background, diagnostic evaluation, and clinical usefulness of fibroscan were reviewed using various literature and clinical studies. One clinical example-a patient with hepatofibrosis who had been treated with TKM-is presented. Results: The liver fibroscan was approved as a medical device for noninvasive measurement of the hepatic fibrosis level by the Korean Food and Drug Administration (KFDA). Numerous clinical studies have confirmed that its sensitivity and specificity allow it to serve as a substitute for liver biopsy, the present gold standard diagnostic method. The accuracy and reproducibility and lack of technical risks are strong points of the fibroscan; however, it has some limitations for application, especially in patients with obesity or severe hepatitis. One clinical example showed the applicability of the liver fibroscan in herbal medicine-based treatments. Conclusions: The requirement for diagnostic medical devices is an important issue in TKM; therefore, this study provides valuable information for practitioners of TKM.

Packet classification is a key technology of the Internet for routers to classify the arriving packets into different flows according to the predefined rulesets. Previous packet classification algorithms have mainly focused on search speed and memory usage, while overlooking update performance. In this paper, we propose PreCuts, which can drastically improve the update speed. According to the characteristics of IP field, we implement three heuristics to build a 3-layer decision tree. In the first layer, we group the rules with the same highest byte of source and destination IP addresses. For the second layer, we cluster the rules which share the same IP prefix length. Finally, we use the heuristic of information entropy-based bit partition to choose some specific bits of IP prefix to split the ruleset into subsets. The heuristics of PreCuts will not introduce rule duplication and incremental update will not reduce the time and space performance. Using ClassBench, it is shown that compared with BRPS and EffiCuts, the proposed algorithm not only improves the time and space performance, but also greatly increases the update speed.
