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.

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.

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)

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.

총설 : 기후변화 등 잠재적 영향을 고려한 수중 미량오염물질의 관리방향 연구

본 논문에서는 국내·외 미량오염물질의 관리현황을 분석하고, 기후변화 등 수질관리에 영향을 주는 잠재적인 요소를 고려한 미량오염물질의 관리방향을 제시하고자 하였다. 국내에서는 먹는 물 안전성 확보를 위해 수돗물 정수 및 원수를 대상으로 미량오염물질에 대한 실태조사가 꾸준히 진행되었다. 근래에 들어 하천·호소수 중의 미량오염물질에 대해서도 조사가 진행되고 있으나 조사 항목과 횟수가 많지 않아 전체적인 미량오염물질 발생 및 검출 현황을 파악하기에는 어려움이 있었다. 선진국에서는 미량오염물질의 실태조사 외에도 환경 매체에서의 거동, 인체 및 생태위해성, 처리공정 등에 미량오염물질 관리 전반에 대한 연구가 수행되고 있음을 확인할 수 있었다. 향후 기후변화에 따른 기온과 수온의 상승, 수문학적인 순환의 변화 등으로 미량오염물질의 잔류 농도가 증가할 우려가 있다. 또한 물 재이용이 확대되는 과정에서 미량오염물질에 대한 우려가 커질 수 있다. 그러므로 먹는 물 또는 신체와 접촉하는 용도의 용수에 대해서는 사전예방의 관점에서 미량오염물질의 관리를 강화하는 것이 필요하다. 지표수 중의 미량오염물질에 대해서는, 물환경 정책목표 중의 하나인 생태 위해성 관리의 관점에서, 물질의 거동, 생태 위해성 평가, 하·폐수처리공정에서의 제어방안 등에 대한 연구가 확대되어야 할 것이다. In this study, the management polices of micropollutants (MPs) were reviewed and the future management strategy was discussed considering climate change and etc. In Korea, the investigation of drinking water has been actively carried out for the priority contaminants as well as MPs. Recently river and lake waters have been also examined for MPs. However, the coverage and depth of the investigation is limited. Moreover, climate change is likely to increase air & water temperature and it will affect the hydrological cycle. Such changes may increase the residual concentrations of MPs in water system. As water reuse increases, the residual MPs of the recycled water may create public concerns. Thus, in a viewpoint of the precautionary principle, more stringent management of MPs is recommended for the drinking water and the body-contact water use. For the surface water, more studies are necessary to understand the ecological risk by MPs.

The typology of urban block housing is deeply related to the urban form and street system. Mid-rise high-density block housings are relatively new housing forms in Korea where housing developments are divided into the two most common categories; high-rise large-scale complex and individual parcel-based low-rise building. In the year of 2012, the new housing policy has been implemented to enhance the housing re-development based on the urban block. The objective of this research is to develop a design methodology of street?oriented block housing with the optimization of daylight satisfying Rights to daylight and high Floor Area Ratio(FAR). The various preliminary design alternatives are investigated on the typical urban blocks testifying the different block depths and azimuth angle. The application of minium required distance between the two parallel residential buildings at each azimuth angle and the elimination of self-shaded area are employed as the basic principles to determine the building height and plan configuration in Seoul Metropolitan City. The major findings are as follows; First, the street system is need to be widened at least 14m in order to enhance the street activity and to improve daylight conditions of block interiors and streets. Second, at azimuth angle 0°, minimum distances of south-north=1.8h and east-west=0.7h, are required to meet minium two hours of daylighting. Furthermore, the self-shaded area of west building facing east can be eliminated by opening up 14m on the south-wast corner of the building. Third, at azimuth angle 60°, in addition to the design principles described above, the minium distance south-north=1.8h is required to avoid the interference of daylight and shade. At last, the computational simulations show that the suggested design alternatives meet the standard of Rights to light and achieve the high FAR.

1920년대 영미 여성미술가들의 자서전 집필과 자기서사에 대한 고찰

김호정(Hochung Kim) 현대미술사학회 2017 현대미술사연구 Vol.0 No.42

영국과 미국에서 19세기 후반에서 20세기 초까지 주로 활동했던 여성미술가들이 노년기를 맞은 1920년대 동안‘ 자서전’이란 문학 형식을 통해 자신들의 예술 인생의 궤적과 직업적 성취에 대하여 스스로 기록하기 시작하였다. 필자는 본고에서 엘리자베스 톰슨 버틀러, 루이즈 조플링, 애나 리 메리트, 재닛 스쿠더, 세실리아 보라는 다섯 명의 여성미술가들이 집필한 자서전들을 대상으로 서사구조, 서사방식, 서사주제의 특징과 그 배경을 고찰하였다. 그런데 고찰대상들 모두 서사구조를 연대기적으로 구성하는 남성자서전의 특징을 따르지만, 모두가 편지나 일기를 인용하는 여성자서전 특유의 자기서사 방식을 취한 것은 아님을 발견하였다. 서사구조와 서사방식에서 남성적 유형과 여성적 유형의 채택 비중이 저마다 달랐다. 여성미술가들이 공통적으로 다룬 주제들은 예술적 재능을 각성한 유년기 경험, 전문적 미술교육을 받은 과정과 내용, 프로페셔널 미술가로서의 활동경력과 성취한 업적이었다. 공통주제들을 살펴본 결과, 여성미술가들이 주장한 남성과 동등한 미술교육이나 개인적 노력보다는 미술교육을 받을 수 있는 경제력과 남성미술가와 전문가 집단의 인증이 실질적으로 영향을 미쳤음을 확인할 수 있었다. 그것은 모더니즘 미술 시대에 여성미술가들이 남성미술가의 자서전을 모델로 자신들의 인생과 경력을 재구성하고, 아카데미즘에 기초한 과거의 남성중심적 판단기준을 적용하면서 간과했던 점이다. 자서전에 진술한 이야기를 입증하기 위해 도입한 여성적 자기서사에서 그 실마리를 발견할 수 있다는 점에서 여성미술가의 자서전 분석에서의 의미를 찾을 수 있다. Some female artists who worked in the late 19th Century to the early 20th Century England and America made a self narrative on their art life and achievement by the form of ‘autobiography’ in the 1920s. The purpose of this paper is to examine the autobiographies written by five female artists, Elizabeth Thompson Butler, Louise Jopling, Anna Lea Merritt, Janet Scudder, and Cecilia Beaux. Focusing on the narrative structure, narrative method, and narrative theme, I found that not all the autobiographies followed narrative method of women’s autobiography, which is composed of letters or diaries. Although they had similar chronological narrative structure of men’s autobiography. The common themes of autobiographies were the childhood experiences of artistic talent, the courses and curricula of art education, and their professional career and accomplishment. Examining the common themes, I realized that financial ability to afford art education and to gain recognition from male artists and art institutions played a more important role than to give women art education equal to men or stress their personal effort. In the age of Modernism, female artists tried to reconstruct their artistic life and careers following the model of male artists, and to the judge with the phallocentric standards based on the past Academism.
