본 EU는 세계에서 미국을 능가하는 경제력을 가지기 위해서 여러 가지 측면으로 노력하고 있다. 이러한 경제성장은 산업기술발전을 통해서 가능하고 더 나아가 산업기술의 경쟁력강화를 통해 고용창출이 가능하다고 인지하고 있다. 이에 EU집행위에서는 국제기술협력 정책 추진에서 EU내 회원국 간의 국제기술협력이 아닌 비회원국, 즉 한국 등과의 협력이 강화되어야 한다는 것을 강조하고 있다. 우리나라에서 정부기관을 통해서 몇몇의 EU권과의 국제기술협력에 대한 보고서가 나오고 있다. 하지만 아직 학계에서는 EU권에 대한 국제기술협력에 대한 연구가 이루어지지 않고 있다. 이에 본 논문의 목적은 기존에 많은 학자들에게 잘 알려진 미국 및 일본과의 연구를 넘어서서 EU와의 국제기술협력을 할 수 있는 주요한 정보를 제공하는 데에 있다. 제 2장에서는 EU의 일반적인 기술혁신정책을 소개하고 이어서 제 3장에서는 EU와의 국제기술협력을 위한 종합프로그램(Framework Program)을 살펴보고 제 4장에서는 EU권에서 중소기업 및 산업체와 함께 국제기술협력을 할수 있는 주요 프로그램인 EUREKA를 살펴보았다.

PURPOSES : The desire of drivers to increase their driving speeds is increasing in response to the technological advancements in vehicles and roads. Therefore, studies are being conducted to increase the maximum design speed in Korea to 140 km/h. The stopping sight distance (SSD) is an important criterion for acquiring sustained road safety in road design. Moreover, although the perception-reaction time (PRT) is a critical variable in the calculation of the SSD, there are not many current studies on PRT. Prior to increasing the design speed, it is necessary to confirm whether the domestic PRT standard (2.5 s) is applicable to high-speed driving. Thus, in this study, we have investigated the influence of high-speed driving on PRT. METHODS : A driving simulator was used to record the PRT of drivers. A virtual driving map was composed using UC-Win/Road software. Experiments were carried out at speeds of 100, 120, and 140 km/h while assuming the following three driving scenarios according to driver expectation: Expected, Unexpected, and Surprised. Lastly, we analyzed the gaze position of the driver as they drove in the simulated environment using Smarteye. RESULTS : Driving simulator experimental results showed that the PRT of drivers decreased as driving speed increased from 100 km/h to 140 km/h. Furthermore, the gaze position analysis results demonstrated that the decrease in PRT of drivers as the driving speed increased was directly related to their level of concentration. CONCLUSIONS : In the experimental results, 85% of drivers responded within 2.0 s at a driving speed of 140 km/h. Thus, the results obtained here verify that the current domestic standard of 2.5 s can be applied in the highways designated to have 140 km/h maximum speed.

최근에는 회전자에 희토류 영구자석을 삽입하여 높은 효율과 출력밀도를 얻을 수 있는 매입형 영구자석 (IPM: Interior Permanent Magnet) 전동기 또는 표면부착형 영구자석 (SPM : Surface Permanent Magnet) 전동기처럼 영구자석이 사용된 전동기의 연구가 활발히 이루어지고 있다. 영구자석을 사용하기 때문에 릴럭턴스 전동기나 유도전동기와 비교해 효율이 높고 출력밀도가 높은 장점이 있으나 회전자에 영구자석을 삽입함으로써 고속운전 및 영구자석의 감자로 인한 신뢰성 감소, 희토류 금속의 원가 상승 등이 문제시되고 있다. 본 논문에서는 희토류 영구자석 전동기를 대체할 수 있는 미래기술 개발과, 희토류 저감형 전동기와 탈 희토류 전동기의 기술 선점을 요구하는 시대적 이슈(Issue)에 맞춰 영구자석이 필요 없는 스위치드 릴럭턴스 전동기 (Switched Reluvtance Motor, SRM)를 구동시키기 위한 구동 제어에 연구하고자 한다. PSIM 시뮬레이션 프로그램에서 제공하는 3상 SRM library를 이용하여 회전자 위치 정보 센서를 이용한 SRM의 구동 및 제어 시스템 모델링 (Modeling)을 연구하고자 한다.

Bioindustry is rapidly changing. Many biologists redefine biotechnlolgy as 'reprogramming the genetic codes of living things to suit cultural and economic needs and desires.'We regarded this change as the 'paradigm shift'in bioindustry. The genome research is reorganizing agricultural and environmental industries as well as a pharmaceutical industry. By analysing patent data granted in the United States from 1997 to 1999, we tried to explore the international patterns and trends of technological innovation in bioindustry, especially in the genome research. As the result, we could find that the United States'monopolistic position in the bioindustry was consolidated by the genome research. Competitive positions in the countries such as Japan and Germany, however, have been aggravated continuously. Korean inventors weren't also active in many biotechnological areas as comparing to developed countries such as US and UK. Especially, the gaps between Korea and developed countries in genome research were greater than any other areas.

International investment has been gaining the importance in the economic growth, employment and technological spillover for many countries at the time of unrestrained flow of the production resources, inter alia, the capital. International investment is prerequisite for Korea to overcome its resource-scarcity. This paper studied some contentious issues of international investment and attempted to suggest negotiating position for Korea on future FTAs. We have made theoretical research of the issues and derived common denominators from four previous FTAs which Korea has concluded. Based on both theories and evidences, we suggest that Korea be ready to have more open attitude for incoming international investment, that is, foreign direct investment(FDI) in future FTA negotiations although Korea should have rather flexible strategy on international investment issues, on the basis of the reciprocity.

This paper is concerned with the current status and the prospectus of environmental investments in the manufacturing sector. A questionnaire survey was made to identify the concentrated fields of the investments. The collected data were analyzed by a multidimensional scaling method in order to provide a reasonable interpretation on the major factors which characterize the current situation and the prospectus of the investments as well as the relative position of each respondent company in a spatial map. The result tells us most respondents tend to concentrate their attention on end-of-pipe solutions due to technological tangibility and economic efficiency, etc.

To date Korean electronic industry has held a position of the first rank both in productions and exports among the nation's industries. However, it is gradually losing its competitive foundation in the world market owing both to the weakening in price competition by least developed among developing countries(LDDC) and to the lack in technological competition with industrially advanced countries. Specifically it is worried about an industrial subordination to industrially advanced countries owing to an evasion of components supply, control of amount of materials, and the evasion of kernel technology transfer etc. As the condition has developed, both the government and the electronic industry in July of this year came to jointly establish a research and development center for electronic components for the purpose of rehabilitating the electronic industry and accordingly strengthen the export industry which has been and continuance to be vital to our nation.

As the semiconductor industry enters the next century, we are facing to the technological changes and challenges. Optical lithography has driven by the miniaturisation of semiconductor devices and has been accompanied by an increase in wafer productivity and performance through the reduction of the IC image geometries. In the last decade, DRAM(Dynamic Random Access Memories) have been quadrupoling in level of integration every two years. Korean chip makers have been produced the memory devices, mainly DRAM, which are the driving force of IC＇s(Integrated Circuits) development and are the technology indicator for advanced manufacturing. Therefore, Korean chip makers have an important position to predict and lead the patterning technology. In this paper, we will be discussed the limitations of the optical lithography, such as KrF and ArF. And, post optical lithography technology, such as E-beam lithography, EUV and E-beam Projection Lithography shall be introduced.
