최근 국내외에서는 새로운 네트워크 구조 및 프로토콜에 대한 연구 활동이 활발하게 진행되고 있으며, 이러한 연구활동 지원을 위한 테스트베드 및 관련 기술에 대한 연구 활동이 활발히 진행되고 있다. 국내에서는 OpenFlow 프로토콜 기반의 미래 인터넷 테스트베드 구축과 연구자들에게 독립적인 연구 공간 제공을 위한 네트워크 가상화 기술에 관한 연구가 함께 진행되고 있다. 네트워크 가상화는 많은 연구자들이 테스트베드를 공유하면서 각각의 연구에 대해 서로 영향을 주지 않고 테스트 베드 활용을 극대화하는 기술이다. 본 논문에서는 수락 제어 및 사용자의 최소 대역폭 보장을 제공하는 QoS기능을 포함하는 Enhanced FlowVisor를 구현하였다. 또한, OpenFlow 프로토콜 기반의 미래인터넷 테스트베드에서 Enhnaced FlowVisor의 성능 검증을 위한 실시간 비디오 스트리밍 실험을 수행 하였으며, 실험을 통하여 미래인터넷 테스트베드의 가상화된 네트워크에 각각의 연구들에게 서로의 트래픽 간섭없이 신뢰있고 안정적인 QoS 보장을 제공할 수 있음을 확인하였다. Recently, world-wide research activities on new network architectures and protocols are being actively progressed. Furthermore, research activities on testbed and related technologies for supporting those activities are being actively performed. In domestic study, research on the OpenFlow protocol based future Internet testbed implementation and research on its virtualization for supporting independent research experiments are being performed at the same time. The network virtualization is a technology which maximizes the testbed utilization without interfering each other for the individual research when many researchers share the testbed. In this paper, we implemented a Enhanced FlowVisor by extending basic FlowVisor by adding QoS functions which are admission control and minimum bandwidth guarantee. On the testbed, we performed a real-time video streaming experiment for verifying the performance of the Enhnaced FlowVisor on the OpenFlow protocol based future internet testbed. The result shows that the Enhanced FlowVisor can provide reliable and stable QoS to the individual researches without disturbing each other traffic on virtualized networks of the future Internet testbed.

發刊되기 시작한지 몇해 되자않는「History and Theory」라는 歷史理論에 관한 雜誌의 最新號에 실린 Hayden V. White 의 「The Burden of History」는 여러모로 興味있는 글이었다. 歷史家들은 歷史에 대한 批判과 攻擎을 그것이 社會科學者들로부터 提起되었을 때는 歷史는 藝術이리고 몸을 피하고 藝術家로 부터 非難의 화살이 올 때는 歷史는 科學이라고 몸을 피하는 巧妙한 處身을 해 왔으나 19世紀末로 부터 20世紀에 걸쳐 그러한 作戰이 잘 들어 맞지 않게 되었다.
Ta<sub>2</sub>O<sub>5</sub> 고유전박막의 미세조직과 열적안정성

TiN and TaN films as electrode materials of reactive sputtered $Ta_2$$O_{5}$ were prepared by sputtering to compare their thermal stabilities with $Ta_2$$O_{5}$ The microstructural change of $Ta_2$$O_{5}$ films with annealing was also investigated. As- deposited $Ta_2$$O_{5}$ film on $SiO_2$ was amorphous and annealing of 80$0^{\circ}C$ for 30 min made it transform to $\beta$-Ta$_2$O$_{5}$ crystalline which contains amorphous particles with the size of a few nm. Crystallization temperature of Ta$_2$Ta_2$$O_{5}$ on TaN is higher than that on TiN electrode. The interface between TaN and Ta$_2$O$_{5}$ maintained stably even after vacuum annealing up to $800^{\circ}C$ for 1 hr, but TiN interacted with $Ta_2$$_O{5}$ and so interdiffusion between TiN and $Ta_2$$O_{5}$ occurred by vacuum annealing of 80$0^{\circ}C$ for 1 hr. It indicates that TaN is thermally more stable with $Ta_2$$O_{5}$ than TiN.N.
19世紀 前半基의 社會變動과 勞動思想 : Louis Blanc를 中心으로
민석홍 서울大學校 人文學硏究所 1987 人文論叢 Vol.19 No.-
European society of the former half of the nineteenth century was heavily influenced by the Dual Revolution, that is, the French Revolution and the Industrial Revoltion. The Industrial Revolution produced the working class and the problems of labour, though it accomplished the development of modern capitalism. In the nineteenth century the so-called utopian socialists-Fourier, Owen, Saint-Simon-attempted to solve these problems in their own ways. They tried 'to discover a new and more perfect system of social order and to impose this upon society from without by propaganda, and, wherever it was possible, by the example of model experiments. These new social systems were foredoomed as utopians' (Engels). Louis Blanc(1811∼82), born later than these utopians and lived through almost the whole century, showed a more practical and concrete way to socialism. He vehemently condemned the limitless competition of capitalist society and deeply sympathised with the poverty-ridden workers. In order to eliminate such social wrongs he proposed to create 'the social workshop', a kind of producer's corporation. Initially established under state sponsorship, these workships should be run by the workers themselves. Blanc believed that his social workshops would prevail over the existing factories based on competition because of their increased productivity based on fraternal solidarity. In the same way, he expected a fraternal absorption of the bourgeoisie rather than a violent revolutionary triumph over it by the proletariat. Blanc firmly believed that a democratically elected republic would willingly initiate the social revolution without violence and terror. So there would be no dictatorial institutions, for even a brief time. Blan's ideas gained wide popularity among workers during 1840s and had a precarious chance to be realized in the spring of 1848, but failed. Blanc's socialism stood between the utopian socialism and Marxism, chronologically and ideologically. His belief in peaceful transition to socialism may have some connection with modern French humanistic socialism(socialisme humaniste).
