Spherical $MgB_2$ powders was synthesized with the ultrasonic spray pyrolysis(USP) process using aqueous solutions of boron and magnesium ion. The properties of synthesized $MgB_2$ powder were characterized by XRD, SEM and EDS. A small amount of MgO was detected as the secondary phase out of the synthesized powder and the ratios of $MgB_2$ to MgO increased with increasing furnace temperature. The particle size and morphology of $MgB_2$ powder were investigated with varying molar concentration of the boron and magnesium solution and furnace temperature between $600^{\circ}C$ and $1000^{\circ}C$ in $Ar/H_2$. The average particle size of $MgB_2$ showed narrow distribution ranging from 300nm to 400nm. The morphology of particles exhibited mostly spherical shapes and uniform distribution.

말라르메의 시와 백색의 수사학

Que devient-elle la communication, si précieuse et exaltante, entre le poète et le lecteur dans le langage poétique de Mallarmé? Le présent article prend cette simple question pour point de départ. Nous allons adopter, pour y répondre, le point de vue rhétorique, qui ne consiste pas à déterminer quel sens le texte produit, mais à déterminer comment le texte se donne à lire. A première vue, le langage de Mallarmé apparait comme une dénonciation de la transparence du sens et de la forme simple de la communication. De là nait l’exigence, chez Mallarmé, d’une distinction entre 〈langage br’ut〉 et 〈langage essentieI〉, qui fonde une nouvelle rhétorique des genres, et qui oppose par Jà la 〈prose〉 à la 〈poésie pure〉. Faut-il interpréter cette rhétorique mallarméenne comme une aventure poétique, coupée de la communicationavec le public, si caractéristique du langage ordinaire? L’aventure poétique de Mallarmé ne permet-elle pas en effet une communication poétique, c’est-à-dire une communication sinocère et intime à travers “la parole retrempée à sa source”? Nous nous proposons, pour comprendre la visée communicative de cette parole poétique, d’analyser un poème de Mallarmé. Soupir. C’est de l’analyse même de l’analogie en tant que figure rhétorique et du mot blanc dans ce poème que pourrait être tiré le mode communicatif propre au Iangage poétique de Mallarmé.

This paper proposes a distributed model predictive formation control algorithm for a group of unmanned ground vehicles (UGVs) with guaranteeing collision avoidance between UGVs. Generally, the model predictive control based formation control has a disadvantage in that it takes a long time to compute control inputs when considering collision avoidance between UGVs. In this paper, in order to overcome this problem, the formation control algorithm is implemented in a distributed manner so that it could be individually controlled. Also, a collision-avoidance method considering real-time is proposed. The proposed formation control algorithm is implemented based on robot operating system (ROS), open source-based middleware. Through the various simulation tests, it is confirmed that the formation control of five UGVs is successfully performed while avoiding collisions between UGVs.

시와 부정성 : 쟝 코앙의 부정성의 시학에 대한 고찰 une etude sur la poetique de la negativite de Jean Cohen

박성창 한국불어불문학회 1999 불어불문학연구 Vol.40 No.1

Jean Cohen est le fondateur d'une poe´tique reposant sur la notion d'e´cart. Son ouvrage principal, Structure du langage poe´tique, est en effet une e´tude des proprie´te´s communes a` un certain type d'oeuvres litte´raires, appele´es "poe´sie" qui se distingue nettement de la "prose". Il conside`re ainsi la poe´sie comme un e´cart par rapport a` la norme qu'est la prose. La seule ta^che de sa poe´tique est de de´finir la "poe´ticite´" propre a` la poe´sie. Ce n'est pas tant son projet d'une poe´tique comme science de la poe´sie qui nous inte´resse que la fac¿on dont il fonde la poe´tique ainsi conc¿ue : la notion d'e´cart, qui est a` la base de la de´marche rhe´torico-stylistique, fournit le principe me^me de la poe´tique. Par son objectif et sa me´thode, la poe´tique de J. Cohen rejoint plusieurs domaines voisins : la stylistique, la statistique et la rhe´torique traditionnelle. Apre`s avoir examine´ la fac¿on dont Cohen rapproche la poe´tique de ces trois domaines, nous avons propose´ d'nommer "me´thodologie de la ne´gativite´" celle qui est au centre de la poe´tique fonde´e sur la notion d'e´cart. Cela est du^ selon nous au fait que l'ide´e que Cohen se fait de l'e´scart poe´tique correspond moins au concept de de´viation qu'a` celui de transgression. La poe´sie se caracte´rise ainsi non seulement par un e´cart syste´matique par rapport aux normes de la prose, mais par leur transgression syste´matique : elle en est la contradiction me^me. En d'autres termes, la poe´sie ne veut pas e^tre autre chose que la prose mail veut e^tre anti-prose. C'est en ce sens que la me´thode utilise´e par Cohen est pluto^t ne´gative que comparative ou contrastive. Or cette ne´gativite´ que manifestent surtout tous les proce´de´s poe´tiques ou "figures" utilise´s par le poe`te n'est pourtant que provisoire, et elle constitue. d'apre`s Cohen, l'envers d'une positivite´ plus fondamentale. La ne´gativite´ est en effet le chemin incontournable vers la positivite´. Le me´canisme du poe´tique se devise ainsi en deux temps : un temps purement ne´gatif, et un second, positif. A ce stade positif, la poe´sie ne se de´finit plus comme une de´viation par rapport a` un autre mode`le, mais comme une structure de´termine´e, lie´e a` une fonction qui lui est spe´cifique, une fonction poe´tique. Ce n'est donc plus a` une poe´tique encore ne´gative mais a` une seconde poe´tique, une poe´tique positive, que Cohen confie la ta^che de de´couvrir cette fonction poe´tique, qui ne passe plus anormale. En laissant ouvertes les questions sur cette poe´tique positive, nous avons tente´, dans cette e´tude, de de´gager quelques points essentiels concernant la nature exacte de la poe´tique ne´gative et le passage de celle-ci a` la poe´tique positive.

민족문학-세계문학론의 비판적 검토 : 경쟁적 모델과 순환적 모델

박성창 한국비교문학회 2013 比較文學 Vol.0 No.60

Although the concept of World Literature (as a theory) is a necessity, it is also at the center of much academic controversy. Common questions about the definition of World Literature include the following: 'who' decides what is World Literature? Once that is answered, 'where' is World Literature to be located? When we say World Literature, 'what' kind of literature do we mean? When we say 'World", 'whose' world do we mean? What is the method of defining this 'World'? Can we accept and agree with this definition? Despite such controversies that surround World Literature, the concept has emerged as the core issue of current comparative literary studies. In this paper, we have attempted to examine the pros and cons of the competitive and the circulatory models of World Literature that the Western academics are actively discussing today. The competitive model that Casanova and Moretti suggest do not consider elements other than that of 'nation' and 'competition', and understand World Literature as a model that is based on the competition among the nations only. Damrosch's theory of World Literature focuses on various and fluid circulation and distribution of literary works, and can be called the 'circulatory model.'We seek to examine how the competitive model of the Minjok-World Literature, which represents the Korean theory of World Literature, formulates its reasoning, and what kind of issues emerge from this logic, and how the circulatory model may reveal certain aspects that are not paid attention to in the competitive model. The reason why Casanova and Moretti's competitive model is important for the theory of Minjok-World Literature is because the model places high regard on the possibility of marginal literature. In this view, Korean Literature belongs in the sphere of marginal literature, and the competitive model assumes that such literature has a higher possibility to reform in the field of World Literature than those literatures of nations at the center. On the other hand, in the competitive model, the problems of translation and writing cannot be considered closely. An attempt to expand the sphere of conceptual meaning through negotiating with the concept of 'World Literature' is important. However, this can only be problematic if such a discussion ultimately returns to the basic field of the Minjok (ethno-nationalist) literature. There is a need to reason Korean theory of World Literature not as a competitive model but fas a circulatory model.
