This paper presents an econometric model for measuring basic research capacity index(BRCI) of each OECD countries and analyses the gap in terms of time lag measured and forecasted in connection with factor analysis and BRCI progress function. Based on the analysis, gross domestic expenditure on R&D(GERD), total R&D personnel higher education expenditure on R&D(HERD) and number of science and technical papers based on SCI are more effective than other factors to BRCI. Also, BRCI progress function shows that 29 years is needed for Korea to catch up the level of German's BRCI of year 1998. But, it's impossible for Korea to catch up US and Japan. Therefore, with restricted scientific resources, Korea's own strategy for strengthening basic research capacity is going to be more important in 21st century.

세계 정보서비스기관들은 이용자들이 요청한 질문에 답변을 제공하고자 글로벌협력 메커니즘을 이용하여 협력형디지털정보서비스(collaborative digital reference service: CDRS)를 제공하고 있다. 한국과학기술정보연구원(KISTI)은 Question포인트+서비스를 통하여 글로벌협력 메커니즘을 활용한 CDRS를 이용자에게 제공하고 있다. KISTI에서 개발된 글로벌협력 메커니즘은 두 가지 유형이 있다. 하나는 글로벌네트워크를 이용한 것이고 다른 하나는 독일 기관과 직접 협력에 의한 것이 있다. 본 연구는 이용자를 만족시키는 서비스를 제공하기 위하여 현재의 글로벌 메커니즘을 분석하고 CDRS 글로벌협력 메커니즘의 미래 모델을 제시한다.

To promote fuzzy logic in industrial applications, the German Association of Mechanical and Electrical Engineers(VDI/VDE) established the work group UA451, focusing on "Fuzzy Logic and Fuzzy Control" in 1991. The group focuses on two activities: providing information platforms for designers to exchange project experiences and fuzzy logic standardization. This article presents some of the intermediate results of the standardization activities and discusses future standards for fuzzy logic systems.

There are numerous crashed deaths or near-miss accidents in everywhere. The outbreak place is not just developing countries such as India and Iran, but also leading countries including Japan and German. The crashed death of pedestrian seems to be an unavoidable accident. However, it was revealed in social psychology field that the accident can be treated as a kind of physical phenomenon. In this study, we apply discrete element method frequently used in the field of two-phase flow to pedestrian flow with collective behavior psychology. This approach is a field of social science and physics, called computational sociology. The acquired results show that emergency exit size can be related with the wall slope of the exit.

Hot water extractives of sawdust/particle from domestic and foreign wood species, which were composed of pitch pine, Korean pine, larch, Italy poplar, acacia and oak as Korean wood species, Malaysian oil palm and German spruce were quantitatively analyzed with thin layer chromatography. Sugar components of saccharose, galactose, glucose, fructose and arabinose were contained in these wood species. It was assumed that arabinose and glucose are major inhibitory components against cement hardening in larch and oil palm, respectively, since both species contain a large amount of each sugar. In contrast, fructose might not influence so badly on a cement hardening, when considering that fructose was contained much in Italy poplar with a good cement hardening character. Galactose was a minor component.

The current paper discusses the two most widespread and contradictory educational philosophies of classic German Idealism and modern American pragmatism. Their perspectives of what is truth and what is the best way to distinguish the reasoning idealists from the experienced pragmatists. The implementations of Idealism and pragmatism have affected the education process for several ages and reflect various social changes. The role of schools, educators, environment, teachers, and learners are not the same in both philosophies. However, on reviewing the chronological transmission from Plato's Idealism to Dewey's pragmatism, the resemblances and differences are elaborated here with examples. Furthermore, how these philosophies helped founding advocators for perennialism, essentialism, progressivism, and reconstructionism.

Free and open source software (FOSS) has created a large pool of source codes that can be easily copied to create new applications. However, a copy should preserve copyright notice and license of the original file unless the license explicitly permits such a change. Through software evolution, it is challenging to keep original licenses or choose proper licenses. As a result, there are many potential license violations. Despite the fact that violations can have high impact on protecting copyright, identification of violations is highly complex. It relies on manual inspections by experts. However, such inspection cannot be scaled up with open source software released daily worldwide. To make this process scalable, we propose the following two methods: use machine-based algorithms to narrow down the potential violations; and guide non-experts to manually inspect violations. Using the first method, we found 219 projects (76.6%) with potential violations. Using the second method, we show that the accuracy of crowds is comparable to that of experts. Our techniques might help developers identify potential violations, understand the causes, and resolve these violations.

In recent years, dense small cell network has been deployed to address the challenge that has resulted from the unprecendented growth of mobile data traffic and users. It has proven to be a cost efficeient solution to offload traffic from macro-cells. Software defined heterogeneous wireless network can decouple the control plane from the data plane. The control signal goes through the macro-cell while the data traffic can be offloaded by small cells. In this paper, we propose a framework for cell virtualization and user association in order to satisfy versatile requirements of multiple tenants. In the proposed framework, we propose an interference graph partioning based virtual-cell association and customized physical-cell association for multi-homed users in a software defined small cell network. The proposed user association scheme includes 3 steps: initialization, virtual-cell association and physical-cell association. Simulation results show that the proposed virtual-cell association outperforms the other schemes. For physical-cell association, the results on resource utilization and user fairness are examined for mobile users and infrastructure providers.
