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.

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.

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.

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)

본 연구는 변혁적 리더십이 거래적 리더십보다 리더십 효과가 크고 변혁적 리더십은 거래적 리더십의 효과를 증폭시킨다는 선행연구들의 결과를 한국의 행정조직과 기업조직내 중간간부들의 리더십을 대상으로 검증한 것이다. 검증결과 기업조직에서는 선행연구의 결과와 일치하는 것으로 나타났으나, 행정조직에서는 상반되는 결과가 나왔다. 행정조직에서는 변혁적 리더십보다 거래적 리더십의 효과(조직몰입에 미치는 영향)가 오히려 더 컸으며 변혁적 리더십의 증폭효과보다 거래적 리더십의 증폭효과가 더 큰 것으로 밝혀졌다. 그 결과 행정조직은 기업조직보다 변혁적 리더십과 조직몰입간의 관계가 현저히 약한 것으로 나타났는데, 그 이유는 행정조직이 기업조직에 비해 기계적 구조에 더 가깝고 리더의 보상제공 권한이 보다 제한적 이어서 행정조직에서는 변혁적 리더십의 효과가 제대로 발휘되지 않기 때문이다.

회화적 조형매체로서의 티파니 스테인드글라스 창 연구

The one who brought the most epoch-making changes on stained glass art was the American Artist, Lows Comfort Tiffany(1848-1933). He and his own companies - Tiffany Glass Company, Tiffany Glass & Decorating Company, and Tiffany Studios - produced many of ecclesiastical and secular stained glass windows, and that windows commonly called as 'Tiffany Windows'. Through the investigation of these Tiffany Windows, I could find the origins of liberty of express and use on modern stained glass. So, Tiffany and his stained glass work became the most revolutionary turning point since the Middle Ages. This essay is study for influences of Louis Comfort Tiffany's painitng traits and his artistic goal to the changes of stained glass' expression and technical methods. Because Tiffany could make a realistic description with leaded glass as like as his paintings. Tiffany developed new stained glass materials and techniques, then depicting realistic pictorial images with glass could be realized. So, Tiffany Windows could express realistic color, natural shading and gradation, calligraphic outline and drawing, texture and perspective. And these pictorial expressions were related to the development of opalescent glass-'Favrille', mottled glass, drapery glass, copper-foil technique and plating. For Tiffany, stained glass was not the traditional glass art medium, but the new pictorial plastic art medium to complete his artistic goal. That is the "absolute synthesis of color and light" as Dr. Joan Elliott Price pointed. Dr. Price claimed that Tiffany was the Colorist painter and he Knew the M. E. Chevrel's Law of Simultaneous Contrast and the Ogden Rood's chromatic theory. So Tiffany tried to illustrate the 'Colored Light' by painting, but that was hard to paint. Because any of paints couldn't realistically represent the transmission and the reflection effect of light by itself. Therefore, Tiffany took an interest in glass and stained glass art. Because the colored glass was the only material that represent 'color-light' by itself. As like this, Tiffany regarded stained glass as painting, and so he joined his painting traits and techniques to the stained glass. To depict pictorial effect, Tiffany changed traditional stained glass materials and methods. Tiffany used leading as outline or drawing, and he replaced deceiving enamel painting by genuinely inherent colored glass effect. These revolutionary changes approved that stained glass could express pictorial illusion successfully. At last, Tiffany's concept of stained glass as the pictorial plastic art medium brought about the secularization of stained glass and new themes-still-life, landscape, and floral landscape. In addition, Tiffany applied an electronic lighting to the stained glass. That new lighting system helped the stained glass get liberty of place and time. And so far, stained glass could be installed anywhere, enjoyed anytime, and created as an art object. In conclusion, Tiffany's stained glass windows provided the basis of the modern stained glass art as the plastic art medium.

이 연구는 누리-세종학당의 교수·학습 자원의 활용도를 제고하기 위하여 콘텐츠의 분류 체계화를 시도하고 메타데이터의 설계 방안을 논의하는 것을 목적으로 하였다. 온라인 콘텐츠의 활용도를 향상하기 위해서는 사용자가 자신의 필요에 따라 콘텐츠에 즉각적으로 접근하여 원하는 정보를 검색하고 활용할 수 있는 체제가 구축되어야 한다. 이를 위하여 이 연구에서는 기존의 누리-세종학당의 콘텐츠 분류 기준 및 검색 기능이 얼마나 용이하고 효과적인가를 분석하였다. 이어 도출된 분석 결과를 토대로 콘텐츠 간의 유기성 및 통일성을 높일 수 있는 분류 기준 및 체계화 방식을 제안하였다. 또한 콘텐츠의 검색 기능 강화를 목적으로 메타데이터의 주요 요소를 추출하고 그 설계 방안을 마련하여 제시하였다. 이러한 연구는 그간 한국어 교육연구에서 주요하게 다룬 교육 자료 `개발` 외에 교육 자료의 `효율적 관리 및 활용`이라는 목적 하에 웹 자원을 분석하고 탐구하였다는 데에서 의의를 찾을 수 있을 것이다. This study examined the classification criteria and metadata elements as a way to improve user utilization at Nuri-Sejong Institute (www.sejonghakdang.org). The improved content utilization should provide immediate access to contents depending on user needs, which is directly related to the structuring and searching capabilities of contents. The study analyzed and examined web resources at Nuri-Sejong Institute to determine whether they are provided in accordance with user`s convenience. Then, it proposed classification criteria and metadata elements that reflect user`s perspective and presented them as a way to improve the content utilization. The significance could be identified because this study looked at web resources in terms of management and utilization, not development.
