We provide a fudamental set of information on technologies in the area of mechanical engineering to draw action plans for intermationalization of the National R&D activites. First, we design and use a modified Delphi method to evaluate levels of our technological capabilities and developed countries' as well. We investigate technology acquistion methodolgies, technology characteristcs and various aspects of international cooperation in terms of technology. Secondly, we analyze final responses of participants (i.e,. the third round results of Delphi method) tosee the correlation between various factors in developing mechanical engineering technologies through international cooperation. The technology classification used in this research is developed by STEPI (Science and Technology Policy Institute).

Leakage current of CMOS circuits has become a major factor in VLSI design these days. Although many circuit-level techniques have been developed, most of them require significant amount of designers' effort and are not aligned well with traditional VLSI design process. In this paper, we focus on technology mapping, which is one of the steps of logic synthesis when gates are selected from a particular library to implement a circuit. We take a radical approach to push the limit of technology mapping in its capability of suppressing leakage current: we use a probabilistic leakage (together with delay) as a cost function that drives the mapping; we consider pin reordering as one of options in the mapping; we increase the library size by employing gates with larger gate length; we employ a new flipflop that is specifically designed for low-leakage through selective increase of gate length. When all techniques are applied to several benchmark circuits, leakage saving of 46% on average is achieved with 45-nm predictive model, compared to the conventional technology mapping.

인터넷은 단순한 하나의 테크놀로지가 아닌 생활의 전 분야에 걸쳐 새로운 패러다임을 창출하고 있다. 전 세계로 연결된 인터넷은 정보 전달의 통신수단으로 대체되고 있으며, 최근 푸시기술을 응용한 새로운 형식의 소프트웨어가 솔루션으로 각광받고 있다. 본 연구에서는 이론적인 배경으로 푸시기술의 전반적인 개념 및 응용을 살펴보았고, 실제적으로 어떻게 응용되고 있는지, 특히 가상서점에서의 응용 사례를 들어보면서 앞으로 이 기술이 어떻게 발전해 가야 할지 도서관에서의 활용 방안을 모색해 보았다.

멀티미디어를 사용하는 인간의 측면에서 기술에 대한 이해부족, 고객들의 혼란, 컴 퓨터 산업의 멀티미디어에 대한 잘못된 이해는 멀티미디어 미래를 깊이 생각하게 하고 조사 하게 된다. 멀티미디어 기술이 누구를 위한 것인가라는 질문 없이 무엇을 할 수 있는가라고 묻는 것은 적절한 질문이 아니다. 본 논문은 미디어기술 채택에 관한 과거의 경향에 초점을 맞춰 인간에게 적합한 기술이 어떻게 개발되고 인간의 선택이 어떻게 이루어지는지 조사한다.

지역정보화는 지역개발을 위한 새로운 패러다임으로서 인간축의 견인력(Demand Pull)을 성숙시켜 기술축 주도(Technology Push)와의 조화 속에 진행되는 일련의 변화과정이다. 그러나 변화는 반드시 저항을 수반하게 된다. 모든 정보화 사업이 그러하듯 지역정보화 역시 그 과정에서 발생하게 될 저항을 어떻게 관리하느냐에 따라 성패가 좌우된다 해도 과언이 아니다. 본 소고에서는 지역정보화를 추진하는 과정에서 우리가 당면하게 될 저항 및 집단간 갈등의 근원과 유형, 그리고 이러한 저항 및 갈등을 최소화하고 나아가 긍정적인 수용환경을 조성하기 위한 대안으로서 변화대리인(Change Agent)의 필요성과 활용방안을 변화관리(Change Management) 차원에서 논의한다.

This study had been performed to estimate for vibration characteristics of the Power Motor Coaches with Diesel-Hydraulic Drive and to secure a dynamic characteristic construction technology of another rolling stock. Air bags, springs and dampers of Bogie are carefully reviewed in order to improve ride quality. Dynamic analysis had been performed using VAMPIRE program, which had been developed by BRR, and the analysis results had been compared with test data to verify.

온라인 컨설팅이란 business Consulting, IT Consulting, Tax ＆ Audit Consulting 등의 일반 컨설팅 서비스가 다양한 방식에 의해 Online으로 제공되는 모델을 말한다. 현재 온라인 컨설팅은 시장의 요구에 따른 서비스 발생이 아닌 공급자에 의한 Push-Service라고 할 수 있다. Ernst ＆ Young, Arthur Andersen, Cambridge Technology Partners, IBM, Deloitte Consulting, Robbins-Glola, Mainspring, Bain ＆ Co 등 컨설팅 회사들은 기존 대기업 위주 컨설팅과 함께 특정화된 문제에 대한 특정한 솔루션을 제공하는 저비용 서비스에 의한 중소기업 대상의 신규 시장 창출의 필요성을 느끼고 있다. 또한, 국내 온라인컨설팅의 개념, 선진 컨설팅 업체의 온라인 컨설팅 사업현황, 사업모델, 향후 전망, 사업의 성공요소에 대해서 살펴본다.

Several kinds of photo-chromic polymers containing push-pull structure were synthesized and investigated on optical patterning by photo-induced surface relief gratings (SRG) technique. The azobenzene segment was introduced as a functional group for a photo-triggered tran-cis isomerization. Consequently, we have fabricated micro-size regular pattern by one-step process without photo-mask.

Changes of construction industry entails needs of new construction technologies. In order to address the needs and new challenges, innovative interdisciplinary research programs are considered to be a good solution. To identify such research programs, technology-push and market needs investigations are conducted. Through analysis of international journals and patent maps, technology fusion-based research program are developed. This paper suggest the strategy for technology fusion-based construction process innovation.

Single-ended differential RF circuit topologies fully utilizing complementary characteristics of both NMOS and PMOS are proposed, which have inherent advantage of both single-ended and differential circuits. Using this concept, we propose a CCPP (Complementary CMOS parallel push-pull) amplifier which has single-ended input/output with differential amplifying characteristics, leading to more than 30 dB improvement on $IIP_2$. In addition, complementary resistive mixer is also proposed, which provides not only differential IF outputs from single-ended RF input, but much better linearity as well as isolation characteristics. Experimental results using $0.35{\;}\mu\textrm{m}$ CMOS process show that, compared with conventional NMOS resistive mixer, the proposed mixer shows 15 dB better LO-to-IF isolation, 4.6 dB better $IIP_2$, and 4.5 dB better $IIP_3$performances.
