Tasan put camera obscura which is a perspective of the pin-hole camera to the test and testimony in 1987, and there is a possibility of using in the portrait paintings drawn by Lee Myunggi. The fact that Lee drew portrait paintings using camera obscura would be just a hypothesis until the real documents come out. However the portrait paintings made by Lee having a expression of a three-dimentional effect on corrugation, taking a pose exposed hands, and handling oblique lines on the floor similar to perspective, have a new change by something external. At a guess the thing changed Lee`s art of drawing would be the influence of camera obscura coming from China. Especially at Yu Unho painting made in 1789 there is a phrase that YongCheJangHwal(容體長闊) ShiWonShinGamIlBan(視元身減一半) which it means the reduction ratio of a portrait. Making the recuction ratio of a portrait clear and the beauty of form show the certain fact of using camera obscura. Needless to say, by Tasan`s testimony we can be proud that camera obscura was used in the late Chosun. There are little cases on the evidence or document using camera obscura in the 16th to 19th centuries Western painting history. In this point, the thing which Tasan tested camera obscura and the portraits by it drew, is very valuable in the world scientific history and the painting history. In a way, Tasan and Lee`s test and testimony were very important, as the entering 19th century their achievements remained obscure. Choi Hangi, Lee Kyugyong, and others partly tested optical instruments, but realism of paintings rapidly declined. Lee`s portraits are simple and plain in comparison with Western portraits taking well lighting. But In Lee`s portraits are worth well seeing the using of camera obscura. In the view of exposing the truth of the object, the exploiting on the stereography suitable for our face and clothing is brilliant artistry. So Lee`s portraits can be a good classical example having realism and modernity in the late Chosun cultural history.

본 연구에서는 LPCVD, PECVD, ECR plasma CVD방법을 이용하여 x선 노광 공정용 마스크의 투과막재료로써의 실리콘질화막의 증착과 그의 물성에 관하여 실험하였다. X선 노광 마스크용 투과막의 재질로써 요구되는 적정인장응력에 가지는 증착조건으로 실리콘질화막을 1$\mu\textrm{m}$정도의 두께로 증착하였으며 이 조건에서의 물성을 SIMS, XPS, ESR, AFM, spectrophoto-metry를 이용하여 비교 분석하였다. ECR plasma CVD방법으로 얻은 실리콘 질화막은 화학양론적 조성(Si/N=0.75)에 근접하는 막을 얻을 수 있었으며 표면 평활도와 가시광투과도가 가장 우수한 결과를 얻었다. 저온 증착법인 PECVD로 얻은 막은 Si/N비가 약 0.86정도이고 산소와 수소의 불순물함량이 가장 높게 나타났다. SiH$_{2}$CI$_{2}$를 이용한 LPCVD막의 경우는 Si-rich조성을 가지지만 수소 불순물의 함량이 가장 작게 나타났고 표면거칠기는 가장 나쁘게 나타났다. 그러나 위의 방법으로 얻은 실리콘 질화막의 최대 가시광투과도는 633nm파장에서 모두 90%이상의 값을 나타내었고, 또한 표면 평활도도 0.64-2.6nm(rms)로 현재 연구되고 있는 다른 X선 투과막재료보다 월등히 우수한 결과를 보였다.

CoDisplay : 대형 디스플레이 장치를 활용하기 위한 VNC 기반회의도구

이태호,박지혜,이기훈,이명준,Lee, Tae-Ho,Park, Ji-Hye,Lee, Ki-Hoon,Lee, Myung-Joon 한국정보통신학회 2009 한국정보통신학회논문지 Vol.13 No.8

최근 대형 디스플레이 장치를 활용한 의사전달행위가 보편화되고 있다. 따라서 효과적인 의사전달을 지원할 수 있도록 대형 디스플레이 장치를 효율적으로 공유하는 것이 바람직하다. VNC(Virtual Network Computing)는 데스크톱 공유 도구로서 다른 지역에 위치한 컴퓨터로 데스크톱 화면을 전송할 수 있다. 또한 VNC를 이용하여 두 명 이상의 사용자가 동시에 같은 데스크톱 화면을 사용할 수 있다. 그러나 현재 VNC가 지원하는 기능만으로 대형 디스플레이 장치를 효율적으로 공유하는 것은 어려운 일이다. 본 논문에서는 VNC를 이용하여 대형 디스플레이 장치를 공유하는 회의도구인 CoDisplay 개발에 대하여 기술한다. 회의 참가자들은 네트워크 주소를 이용하여 대형 디스플레이 장치에 접속하며 자신의 데스크톱 화면을 내장된 VNC를 이용하여 전송한다. 또한 여러 데스크톱 화면을 배열하고 전환하는 기능을 통하여 대형 디스플레이 장치를 효과적으로 공유할 수 있다. Since wide display devices have recently become popular for communication activity, it is desirable for effective communication to share those displays in an efficient way. VNC(Virtual Network Computing) is a desktop sharing software, which transmits the desktop screen and the related events to other computers on different places. So, through VNC, it is possible for more than two users to share the same desktop screen at the same time. But it is very cumbersome to share wide display devices through the functions currently supported by VNC. In this paper, we describe the development of CoDisplay which is a VNC-based conference tool for efficient sharing of a wide display device. Conference participants connect to the wide display device through the associated network address, and transmit their desktop screen to the device. The control functions for the participants support the division of the display screen for multiple desktop screens and the switchover of desktop screens.

三國時代 後期 高句麗와 百濟의 四神圖 壁畵

李泰浩(LEE Tae-ho),尹烈秀(토론자) 고구려발해학회 2003 고구려발해연구 Vol.16 No.-

This paper is a study on the mode of expression used in Late wee Kingdoms period mural paintings depicting the Four Gods (四神), the four divine imaginary animals that safeguard the four directions. The Four Gods was a common theme on mural paintings in Goguryeo tombs (高句麗古墳) from the second half of the sixth century to the first half of the seventh, and the four imaginary animals, the blue dragon (靑龍) painted on the eastern wall, the white tiger (白虎) in the west, the red phoenix (朱雀) in the south, and Hyeonmu (玄武), a black creature being a combining the features of a snake and a turtle in the north, were symbols of protection and the repulsion of evil spirits. Due to their exquisite artistic qualities these mural paintings have received attention both nationally and abroad since their discovery and they have been the subject of many studies, but the trend has mainly been to analyze their content. In 1998 I was able to see some of the tombs in the Pyeongyang (平壤) area in person. I analyzed one aspect of these mural paintings that so far has been overlooked, their mode of expression, and based on this I have tried to make a unified reappraisal of the chronology of the Four-Gods Mural Paintings of both Late wee Kingdoms Period Goguryeo and Baekje (百濟). First of all I show that the Late Three Kingdoms Period method of arranging the Four Gods on each wall of the one-chamber tombs didn't appear in Goguryeo first, but rather in the early sixth-century Baekje Song-san-ri tombs No.6 (宋山里6號墳). The people of Baekje developed this Four-Gods tomb style for the first time in the Song-san-ri tomb No.6, being influence by the Chinese Yang Dynasy (梁), a feature it shares with the tomb of king Mu-nyeong (武寧王陵). Furthermore, they invented the unique technique of plastering only the forms of the Four Gods on the brick walls to later paint them. This method was later continued in the late sixth century Goguryeo Four-Gods Tomb of Ho-nam-ri (湖南里四神塚). The Four Gods had been a common motif since the Chinese Han Dynasty (漢), and had appeared as part of mural tomb paintings in Goguryeo for over two hundred years. They grew in relative importance in the late fifth and early sixth century, being no less important than the human-genre paintings and other decorative paintings, and we cannot disregard the possibility that mural paintings depicting only the Four Gods might have emerged in the extension of this. The Four Gods mural paintings of Late Goguryeo rested on a 200 years old tradition of Fresco painting, in the early sixth century adopting and modifying the forms of the Four Gods in the tomb style of the Northerm and Southern Dynasties (南北朝時代), following after Northern Wei (北魏) in China. Moreover, recently cases have been discovered in China from the Sui (隋) and Tang (唐) Dynasties that resemble the Four Gods paintings of late-sixth to early-seventh century Goguryeo, indicating that they also were very active in adopting new modes of expression from abroad. This active attitude gave the people of Goguryeo the momentum to invent independent techniques of mural painting, such as the method of painting directly on the stone surface, as can be found in the Ho-nam-ri Four-Gods tomb, the Tong-gu Four-Gods tomb (通溝四神塚), and the O-hoe tombs Nos.4 and 5 (通溝五??墳 4號ㆍ5號墓), or the method of painting on stone surfaces in slight relief, as can be found in the Gang-seo-dae tomb (江西大墓) and Gang-seo-jung tomb (江西中墓). If we re-arrange the chronology of the tombs into early sixth century, middle and late sixth century, end of the sixth to early seventh century, according to the modes of expression of Four-Gods Mural Paintings of the Late Three Kingdoms as outlined above, it will look as follows. In the early sixth century, the Four Gods motif first appeared in the Song-san-ri tomb of Baekje, and this was continued in the middle and late sixth century in the Ho-nam-ri Four-Gods tomb and jin-pa-ri tombs Nos.4 and 1 (眞坡里4號ㆍ1號墳) of Goguryeo. In this process

과공정 Al-Si 합금에서 초정 미세화 및 공정 Si 의 개량화에 관한 연구

이태호,임성철,김정호,이창희,윤의박 ( Tae Ho Lee,Sung Chul Lim,Jeong Ho Kim Chang Hee Lee,Eui Pak Yoon ) 한국주조공학회 1996 한국주조공학회지 Vol.16 No.4

N/A Hypereutectic Al-Si alloys have many advantages such as excellent wear resistance, high ratio of strength to density, good castability (esp. fluidity) and elevated strength. However, in casting process, the segregation of coarse primary Si and flake eutectic Si decrease mechanical properties. In this study, using AlCuP refiner and Sr modifier, it is intended to obtain simultaneous effects of refinement of primary Si and modification of eutectic Si in hypereutectic Al-Si alloys, to measure hydrogen gas contents and to evaluate mechanical properties. Experimental results show that in the case of simultaneous effect of refinement of primary Si and modification of eutectic Si, two step addition that modifier is added into melt after refiner addition at 750℃ is more effective than simultaneous addition of modifier and refiner at 750℃ in terms of microstructure and hydrogen gas control. All mechanical properties tested were found to be improved by refinement of primary Si and modification of eutectic Si.
