Polyacrylonitrile(PAN)/polyacrylamide(PAAm) and PAN/copolymer(poly(AAm-co-AN)) blend fibers were prepared by solution spinning using nitric acid as a solvent. and stretched to 3, 5 and 7 of draw ratio. The effects of blend ratio and draw ratio on the viscoelastic and shrinking behavior of the fibers were investigated. The peak position of tan § related to Tg of PAH/copolymer fiber shifred towards higher temperature as the content of AN in AAm/AN composition of the copolymer is increased, while the tan 6-peak position of PAn/PAAm fiber has the same as that of pure PAN. The tan 6-peak temperature of PAN/topolymer fiber shifted to lower temperature with increasing draw ratio. The shrinkage of pure PAU, PAM/PAAm and PAN/copolymer fibers increased with increasing heat treating temperature and AN content in copolymers. but decreased with the increment of the draw ratio. It was concluded that the miscibility of the copolymer with PAN is better than that of PAAm and increased with increasing AW content of copolymer.

Weapon systems composed of several subsystems execute various engagement missions in distributed combat environments in cooperation with a large number of subordinate/adjacent weapon systems as well as higher echelons through tactical data links. Such distributed weapon systems require distributed real-time simulation test beds to integrate and test their operational software, analyze their performance and effects of cooperated engagement, and validate their requirement specifications. These demands present significant challenges in terms of real-time constraints, time synchronization, complexity and development cost of an engagement simulation test bed, thus necessitate the use of high-performance distributed real-time simulation architectures, and modeling and simulation techniques. In this paper, in order to meet these demands, we presented a distributed real-time simulation system based on High Level Architecture(HLA) and Discrete Event System Specification(DEVS). We validated its performance by using it as a test bed for developing the Engagement Control System(ECS) of a surface-to-air missile system. The proposed technique can be employed to design a prototype or model of engagement-level distributed real-time simulation systems.

The correct and opportune decision of reengaging the intercepted target is required in order to enhance the engagement performance of the surface to air missile systems that has the ability to defense or attack against various targets at the same time. The engagement efficiency and success of these systems will be largely enhanced by assigning quickly its system resources to the intercepted target and minimizing the waste of system resources for the target which is not able to attack any more. The kill-assessment algorithm has to be able to evaluate automatically whether various targets intercepted by missiles are killed or not on the basis of the reasonable confidence level. The definition of kill assessment is discussed and the kill assessment algorithm is designed reliably by using Kalman filter and a probability theory. Finally its performance is evaluated and analyzed by the Monte Carlo simulation.

Mucinous cystic neoplasms of the pancreas are rare primary tumors. They are low-grade tumors that occur predominantly in middle-aged woman. They usually arise within the tail of the pancreas and manifest as large, multiloculated cystic masses. In most cases, they are confined to the tail or body of the pancreas. All mucinous cystic neoplasms should be considered as mucinous cystadenocarcinomas of low-grade malignant potential. Complete surgical excision alone results in an excellent clinical outcome. We experienced a case of mucinous cystadenocarcinoma of the pancreas with invasion to the spleen in a 66-year-old woman. The mucinous cystadenocarcinoma involving the spleen is extremely rare and there has been no case report in Korea. Distal pancreatectomy and splenectomy was performed. It was concluded that multiloculated cyst developed from pancreatic tail and manifested as a huge splenic cyst. We report this rare case with a review of literature.(Korean J Gastroenterol 2001;38:453-456)

아서 웨슬리 다우Arthur Wesley Dow의‘ 구성’ 방법론이 미국 미술교육에 미친 영향 연구

김호정(Hochung Kim) 현대미술사학회 2016 현대미술사연구 Vol.0 No.39

본 논고는 아서 웨슬리 다우의 미술교육지침서 『구성』(1899)과 다우가 뉴욕의 프랫 인스티튜트와 컬럼비아 대학교 교육대학에서 이를 기초로 실행한 미술교육방법론의 특징을 고찰하는 데 초점을 맞추었다. 나아가서 연구자는 그가 19세기 말과 20세기 초 새로운 미술교육방법론을 주장하였던 배경과 목표를 이해하고, 구성 방법론이 미국 미술교육의 체계와 내용에 미친 영향과 의의를 검토하였다. 다우의 구성 방법론이 20세기 모더니즘 미술에 영향을 미쳤을 뿐 아니라 오늘날까지도 유효한 것은 미술을 선, 노탄, 색채의 기초 요소들과 구성 원리에 의한 종합으로 인식하고 창조해야 한다는 다우의 아이디어가 다양한 시대, 국가, 지역, 또는 매체를 사용한 미술의 분야에서 보편적으로 적용될 수 있기 때문이다. 게다가 그는 『구성』 교육으로 학생들이 스스로 미술에 대하여 사고하는 방법을 익히고 미술에서 보다 다양한 가능성과 자유를 경험할 수 있기를 희망하였다. 그러므로 연구자는 다우가 구성의 공공교육을 통하여 모든 학생들이 자기만의 표현을 자유롭게 할 수 있는 능력을 배양할 수 있게 했다는 점에서 그 중요성을 강조하고자 한다. 아울러 다우가 정규 미술교육과정에 미술 감상과 미술사를 도입함으로써 미술교육의 패러다임 전환에 기여했다는 점도 높이 평가할 만하다. 이로써 미술가들뿐 아니라 미술 감상자들의 미적 이해력도 고양할 수 있었으므로 다우의 구성 교육은 20세기 미국에서 미술과 미술관이 발전하는 데에 기틀을 마련하였다 하겠다. In this study, I researched Arthur Wesley Dow’s radical art teaching methods that were explained in Composition (1899) and his teachings at the Pratt Institute and Columbia University’s Teachers College. I also hoped to gain an insight into why Dow proposed a new method of art education, which reacted against traditional academic teaching, and to assess his influence on the American art education system and its curriculum. Through an investigation of the development of “composition” theory, I discovered that one reason why it is still influential today could be due to the principle of universality. He believed that all art, regardless of whether it is fine or applied art, consists of line, mass of notan(dark-and-light) and color, and these basic elements should have a harmonious relationship through composition principles, that is “synthesis”. Essentially, he believed that art must be appreciated and created by composition. Such an idea could be applied to all ages, nations, and materials or methods of art, making it as of universal concept. Upon completion of this research, I hope to be able to explain that Dow provided the key to those artists who sought freedom of expression. He also contributed to the changing paradigm in public art education, since his ideas not only resulted in better art creators but appreciators. Consequently, Dow and his students made a significant contribution to the subsequent development of American modernism and art educational system in the 20th Century.

루이스 컴포트 티파니의 예술과 아메리카니즘

김호정(Kim Ho-Chung) 서양미술사학회 2011 서양미술사학회논문집 Vol.35 No.-

This thesis is a study of the Louis Comfort Tiffany’s Art and the Americanism. Most of preceeding researches focused on defining Louis Tiffany as an American Art Nouveau glass artist. Curiously, his most typical design styles were eclecticism and realistic naturalism, and these styles were different from the European Art Nouveau style. Therefore, Louis Tiffany must not to be considered only as an Art Nouveau artist anymore. Hence, purpose of this study is to clarify Louis Tiffany’s stylistic differences through ‘Americanism’. In the late 19th Century, Americanism used to be a word defining United States’ national identity by the Theodore Roosevelt. He argued that to realize Americanization, Americans must to invent new models differentiated from the Europeans. Art critics regarded Americanism as a cultural doctrine to be independent of European art tradition. So American artists pursued originality and individuality to be differentiated from the European art, then Americanized art. So I’ll consider how the Americanism influenced on the Louis Tiffany’s Art. At the 1900 Paris Exposition Universelle, American Government decided to show that United States can create one’s own national art. To demonstrate Americaness, U.S. Commissioner John Britton Cauldwell mainly selected domestic artists’ landscape paintings for American fine art exhibition. After 1900, these artists and their American landscape paintings recognized as the “American School”. At this Exposition, Louis Tiffany exhibited many of natural landscape depicting stained glass windows as like as the American School paintings do. And these were leaded glass windows that disusing traditional enamel painting. All the Louis Tiffany’s windows and blown glass objects made of his unique patented opalescent glass, named “Favrile glass”. European judges and critics recognized his art as the original American Art, so he won two grand prizes and many medals. Then American Press reported Tiffany’s prize-winning as the symbol of glory that American art was internationally recognized. Louis Tiffany inspired from English Aestheticism and Arts & Crafts Movement. As an Aesthete-artist, he always pursued for representing natural color-light effect in art. So he constantly tried scientific experimentation and invented new art medium. In consequence, Favrile glass and painted enameling would be invented. That would be recognized as an expression of his individuality and originality differentiated from the contemporary European art, even Art Nouveau. And he also want to be differentiated with the European styles. At first, Louis Tiffany tried to show the American national character through eclecticism. Eclecticism was the one of common traits of American School paintings with the native natural landscape theme. He mixed Western & Oriental arts or synthesized Japonisme design’s natural theme with American native species, for creating more differentiated design from the European Art Nouveau-Japonisme style. Then Louis Tiffany found another new way to create original American style. Because of American people likes illustrated images of American native nature. To develop his own unique American style, Louis Tiffany attempted to depicting native natural landscape pictorially in leaded glass windows, enamel-on-copper works, Jewelry. Through this study, It was revealed that Tiffany’s natural landscape designs resembled with the American Pre-Raphaelites’ natural studies and the Hudson River School’s landscape paintings. Such designs could be regarded as examples of the authentic American style and the Louis Tiffany’s art works. He also developed decorative media and designs artistically, so he was capable to be recognized as the pioneer of American Arts & Crafts and artistic design. Therefore, It could be said that Americanism was the Louis Tiffany’s artistic motive and goal either.
