The VR / AR market has grown significantly due to the development of Virtual Reality and Augmented Reality, the core technologies of the Fourth Industrial Revolution. According to a report released by the Korea Science and Engineering Corporation (KISTEP), the global VR / AR market will grow to $ 105 billion by 2022. An important key to the growth of the VR / AR market is user immersion. VR is dependent on technology of hardware such as display and sensor for biometric signal recognition. In order to improve user's immersion feeling, it is important to transmit sensor data to display device more accurately and quickly. In this paper, we consider various sensor hardware dependencies of VR, and compare various correction methods and filtering methods to lower the Motion to Photon (MTP) time that user movement is fully reflected on the display using sensor devices.

전력산업에서 전원설비계획은 매우 중요한 요소이다. 전원설비계획중 발전소 설립에 대한 연구만큼 송전선 증설에 대한 연구도 필요하다고 생각한다. 송전선 증설시 고려해야 될 사항이 많이 있으며, 그것을 체계적으로 정리하여 쉽게 모형화해서 구할 필요가 있다고 생각한다. 이 논문은 좀 더 최적화된 송전선 증설을 위한 모형을 만들어 가는 방향을 제시하고자 한다. 최적전력조류계산(OPF)에 송전선 증설에 따른 비용을 포함하는 모형으로 발전시키는 것을 목표로 하여 다음과 같이 논하고 있다.

최근 팀 다양성이 팀 창의성에 미치는 영향에 대한 연구가 주목을 받고 있으나 팀 다양성이 팀 창의성으로 발현되는 과정과 팀 다양성의 조건 하에서 팀 창의성이 촉진되는 조건에 대한 연구는 제한적으로 이뤄졌다. 국내 24개의 연구개발팀을 대상으로 조사한 결과, 팀 다양성, 특히 정보다양성이 팀 창의성에 긍정적인 영향을 주는 것을 증명하였다. 또한, 팀 구성원간 갈등은 팀 다양성과 창의성 사이에서 유의한 매개효과를 발휘하지 못하는 것을 확인하였다. 변혁적 리더십은 정보다양성과 직무 갈등 사이에서 부(-)의 조절효과를 보였다. 예컨대, 변혁적 리더십이 강하면 정보다양성이 높은 팀일수록 직무 갈등이 낮게 나타났다. 저자는 팀 다양성과 창의성 사이에서 갈등의 조절효과를 증명하기 위해서는 특히 동양권 국가에서 보다 면밀한 측정 방법이 요구되며 팀 다양성이 주는 가치(value in diversity)를 높일 수 있는 잠재적 매개변수의 탐색이 필요하다고 제안하였다.

최근 정부 R&D 방향을 보면 정부출연연의 역할은 중장기, 대규모 신규사업발굴에 초점을 두고 있으며 출연연 자체적으로 연구기획에 많은 투자와 노력을 하고 있다. 하지만, 출연연 주요사업 연구개발계획서에 철저한 준비가 되어야 함에도 기획 전문지식이 체계적으로 축적되지 않았으며 연구기획에 대한 좋은 본보기를 요구하는 연구자들이 지속적으로 이어져왔다. 이에 본 연구에서는 논리적이고 심도있는 검토를 거치는 사전평가 과정인 국가연구개발 예비타당성조사 사업을 본보기로 제안하며 주요사업 기획에 도움이 되는 평가항목들과 내용을 메타분석하고자 한다. 이를 위해 KISTEP에서 공개한 예비타당성조사 보고서의 평가항목들 중에서 출연연 주요사업에 적용될 수 있는 기술적 타당성 평가항목들을 선별한다. 그리고, 선별된 평가항목들끼리의 내용분석을 통해 사업 타당성에 대한 지적사항을 항목별로 정리하여 시사점을 찾아내고자 한다. 본 연구를 통해 주요사업 대규모, 중장기 연구기획 시 실무적으로 도움이 될것으로 기대한다.

This study develops reeducation programs to satisfy needs conducted by the analyses of potential customers and present R&D education programs. The results of this study were derived using the data collected from 200 R&D researchers and control managers occupied in research centers. By analyses of the survey, results showed that the professional R&D reeducation institution and specialized education programs according to career and position were needed. To bring solution of the researcher's reeducation, the establishment of R&D Supreme Academy is essential for effective human resource development and management in R&D.

Both ground and space telescopes are being built larger and larger. Accordingly, the secondary mirrors become larger which are convex mostly on the surface form. Testing convex mirrors becomes more difficult and delicate than testing concave mirrors in optics, because additional optical components are needed to make the reflected rays converge. Hindle type tests are frequently used for measuring the surface deforms of convex mirrors, which employs a meniscus lens to reverse the diverted rays from the mirrors. In case of testing large convex mirrors by using Hindle type tests, attention would be needed as larger meniscus lens is required. A method of modified Hindle test has been studied and the characteristics are analyzed. In this paper, current method of testing convex mirrors is presented, and a new method is discussed.

This paper suggests the concept of the innovation management. Above all it is important to make excellent application of the management for the S&T Research Council and Government Sponsored Research Institutes. This paper will discuss three critical issues that is, the first, what makes clear a point of different strategy for the organizational and the technological innovation focused organization. Second, how makes containing the environmental factors and the target of the innovation into the innovation management strategy. Third, how achieves the performance through the managing innovation. We present a modified BSC strategy in order to manage innovation and to set up a platform for sustaining to deal with the innovation.

본 연구는 혁신목적과 사회적 자본간의 관계를 탐색적으로 고찰하친 있다. 기업의 혁신목적 유형에 따라 사회적 자본의 특성이 다르게 나타나는가를 분석한다. 이를 검증하기 위해 본 연구에서는 2005년 6월에서 7월 사이에 실시된 $\ulcorner$경북 IT기업 기술혁신활동 조사$\lrcorner$ 에서 나타난 176개 기업자료를 실증적으로 분석하였다. 분석은 IT기업의 기술혁신 유형변수로 '탐색형 기업', '활용형 기업'으로 구분하였고, 사회적 자본은 네트워크의 범위를 나타내는 '구조적 변수'와 강도를 나타내는 '관계적 변수'로 구분하여 구성형태를 분석하였다. 분석 결과, 탐색형 기업에서는 네트워크의 범위가 넓고(sparse network) 약한 연계(weak tie) 관계를 가지는 반면, 활용형 기업에서는 네트워크가 범위를 좁고(dense network) 강한 연계(strong tie) 관계를 가지는 것으로 나타났다.

This paper presents the economic validity with the cost/benefit analysis on establishing R&D Supreme Academy. To evaluate the profitability of R&D Supreme Academy, willingness to pay (WTP) is measured by contingent valuation method (CVM) and then the net present value (NPV), internal rate of return (IRR) and benefit/cost ratio(BCR) are calculated. The results of economic evaluation verified that the establishment of R&D Supreme Academy is timely and effective in an economic perspective.

Employing female in the field of science and engineering is becoming increasingly important with diversity and creativity emerging as key factors to build Creative Economy. Under these circumstances, it is necessary to recognize and discourage gender discrimination in the labor market by analyzing wages - the market value of labor which determines one's economic status. This study uses the Oaxaca-Ransom decomposition (1994) to analyze the gender wage gap and identify factors influencing the pay gap in science and engineering labor force. The results of this study are as follows: First, the average wage of female scientists and engineers reaches only 65% of that of male labor force, and the male scientist and engineers are superior in terms of personal attributes, for instance, education background. Second, looking at the factors that influence wages, wage premiums are associated with higher education background, older age, longer period of service, and weekly working hours for both male and female in managerial positions. Third, the wage decomposition shows that in the case of science and engineering labor force, the productivity difference by personal attributes reaches about 58%, and gender discrimination by the characteristics of the labor market stands at about 41%. This means the wage gap by productivity level in science and engineering labor force is wider, and the gender gap is smaller compared to non-science and engineering fields. However, the results of an analysis on specialties and education background of male and female scientists and engineers suggest that the discrimination against women is more serious when the percentage of the female labor force is low and the percentage of temporary workers in the labor market is high. In order to eliminate this discrimination, it is necessary to reduce the imbalance of female scientists and engineers in the labor market, among others, while female scientists and engineers, themselves, need to make continuous efforts to strengthen their capabilities.
