We propose a novel application of random forest, a machine learning-based general classification algorithm, to analyze the influence of design attributes on the silicon-to-SPICE (S2S) gap. To improve modeling accuracy, we introduce magnification of learning data as well as randomization for the counting of design attributes to be used for each tree in the forest. From the automatically generated decision trees, we can extract the so-called importance and impact indices, which identify the most significant design attributes determining the S2S gap. We apply the proposed method to actual silicon data, and observe that the identified design attributes show a clear trend in the S2S gap. We finally unveil 10nm key fin-shaped field effect transistor (FinFET) structures that result in a large S2S gap using the measurement data from 10nm test vehicles specialized for model-hardware correlation.

Gap and thickness difference information between blanks are often necessary for tailored blank welding quality evaluation , optimum welding parameters selection and evaluation of shearing machine, blink allocation device accuracy and clamping device. We develope 3D vision system and camera unit using structured lighting for this purpose. A simple ar d efficient scheme for gap and thickness feature recognition Is developed as well as measurements. Experimental results shows this system measuring accuracy is 10 ${\mu}{\textrm}{m}$ and 16${\mu}{\textrm}{m}$ for gap and thickness difference respectively The data are expexed to be useful for preview gap control.

본 연구에서는 전자구조 계산을 통해 태양전지의 소재로 적합한 Graphene과 h-BN의 합성물을 찾아내었다. 태양전지가 최대 효율을 가지려면 소재의 band gap이 약 1.2 eV이어야 하는데, 본 연구에서는 이러한 물질을 다수 찾아 내었고 이런 물질들의 특징을 분석하였다. carbon domain이 넓을수록 band gap이 작았고 carbon ring이 유지될수록 cohesive energy가 컸다. 이를 다시 적용하여 적합한 구조를 예상하였으며 이와 잘 맞는 계산결과를 얻었다.

The domestic cultural contents industry has been growing rapidly since the 2000s. The government has designated the cultural content industry as the next generation domestic growth industry. In order to cultivate this, various regulations are made and the budget is supported. Local governments are preparing various policies of cultural contents industry. This study presents the economic ripple effect by analyzing the status level and competence of the cultural contents industry in region based on LQ(location quotient) analysis and GAP analysis. Through this, this study will examine the competitiveness of the cultural content industry with high added value in Busan and draw out the plan for activation of cultural contents. Also, this study will compare competitiveness of Busan with other regions and show the economic contribution of Busan City.

정보화 서비스를 제공하기 위해서는 사실 기반의 데이터, 데이터의 전달을 위한 네트워크기술, 그리고, 정보를 원하는 목적에 맞게 처리하여 원하는 사용자에게 전달하여 부가적인 가치를 부여하게 하는 응용 소프트웨어로 크게 나눌 수 있을 것이다. 이러한 응용 소프트웨어 중에는 기술적, 관리적, 문서적인 측면에서 체계적으로 관리되어 있지 않아, 그 상품성을 제대로 인정 받지 못해 진정한 가치를 평가 받고 있지 못하고 있는 실정이다. 따라서, 일반 응용 소프트웨어를 상품화하여 제대로 그 가치를 평가 받을 수 있도록 준비하는 과정을 제안하고자 한다.

Library and information service (LIS) of academic libraries plays an important role in the education and research activities of universities. Such importance of LIS facilitated much research that defines the quality factors constituting LIS and identifies the importance of them. The previous literature, however, has some limitations. The limitations arise from the interrelationship among the quality factors and the perception gap between users and providers on LIS quality factors. Despite the understanding of the interrelationship and the perception gap, LIS studies to deal with both dimesions synthetically are sparse. Therefore, this paper defines the interrelationship among LIS quality factors as a network model, then identifies the perception gap on LIS quality factors by exploiting the analytic network process. As an early stage study, this paper contributes to helping the quality improvement of acedemic LIS by considering the interrelationship among LIS quality factors and the perception gap on the LIS quality factors between LIS users and providers.
