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.

이태호,정창영,이규한,이승윤,안진호,Lee, Tae-Ho,Jeong, Chang-Yeong,Lee, Gyu-Han,Lee, Seung-Yun,An, Jin-Ho 한국재료학회 1997 한국재료학회지 Vol.7 No.5

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.

The present study was carried out to compare the composition of major essential oil components in the flue-cured tobacco produced by Korea, America, China, Brazil and Zimbabwe. Above 100 essential oil components were separated by GC and major 18 components of them, known to be important contributors to flue-cured tobacco flavor and smoke taste, were identified by GC/MS. Neophytadiene was major in quantities in the oils mostly and its composition in flue-cured tobacco produced by Korea, America, Zimbabwe, Brazil, and Unnam and Yenji region of China was 26.82\%,\;25.17\%,\;26.50\%,\;16.92\%,\;and\;18.75\%\;and\;14.87\%$, respectively. Megastigmatrienone, one of the major tobacco carotenoid degradation products was contained above $10\%$ in the oils of flue-cured tobacco produced by Korea and America, but, it was comprised about $5.66\%$ to 8.00 in Brazil, Zimbabwe, and Unnam and Yenji region of China. Damascenone is important to the aroma of tobacco as a crotenoid degradation products. Its amount in the oils was $3.31\%\;in\;Brazil,\;3.13\%\;in\;America,\;2.57\%\;in\;Zimbabwe,\;2.54%$ in Yenji of China, $2.00\%$ in Korea and $1.85\%$ in Unnam of China. These results can furnish the basic information capable of evaluating the quality value of flue-cured tobacco produced by various nations.

램제트(RAMJET) 추진기관에 대한 전망

이태호,Lee, Tae-Ho 한국방위산업진흥회 1992 國防과 技術 Vol.- No.156

무궁무진한 대기속의 산소를 산화제로 사용함으로써 일반 로케트보다 월등히 높은 비추력을 얻을 수 있는 램제트는 유럽과 소련에서는 이미 실용화 되어 있으며, 미국에서도 활발한 연구가 진행되고 있다. 이러한 선진국들의 활발한 연구와 이의 실용화에 비해 국내에서는 이에 대한 연구가 거의 없는 상태이므로 앞으로 학계에서의 활발한 연구가 기대된다

IAWQ MODEL NO . 1 에 의한 산업폐수처리장의 처리능력평가

이태호,신훈길,김창원,한기백 ( Tae Ho Lee,Hun Gil Sin,Chang Won Kim,Ki Bak Han ) 한국물환경학회 1995 한국물환경학회지 Vol.11 No.3

Mathematical models have been developed to understand and optimize the biological wastewater treatment process. In this research, SSP(Simulation of Single sludge Process) program, based on IAWQ model NO.1, was used to evaluate treating capacity of a pertrochemical wastewater treatment plant. The biokinetic and stoichiometric coefficients were calibrated and verified, and then the treatment capacity was estimated. Sensitivity analysis showed that the effluent COD concentration was greatly influenced by the parameters such as μ_H, K_S, and K_(dH) and MLVSS was affected by Y_H and K_(dH), while other parameters hardly had any effect. The calculated kinetic and stoichiomertric coefficients were μ_H, 9day¹, k,_COD 80㎎/ℓ, K_d 0.133 and Y_H 0.515 gCOD/gCOD. However, verification resulted relative error of 30%∼40% which was maybe due to different operating condition in 1991 and 1992. As a result of estimating the treatment capacity, the maximum allowable volumatric loading rate would be 1.35㎏/㎥·day based on MLVSS of 8,000㎎/ℓ. This means that the treating capacity of 1992 can be incereased up to 24%

Objective The aim of this study is to investigate if Sweet Bee Venom therapy has the equal effect in comparison with Bee Venom Therapy on Low back pain with Radiation pain. Methods Clinical studies were done 24 patients who were treated low back pain with radiation pain to Dept. of Acupuncture & Moxibusition, of Oriental Medicine Se-Myung University from April 1, 2007 to September 30, 2007. Subjects were randomly divided into two groups ; Bee Venom treated group(Group A, n=10), Sweet Bee Venom treatred group(Group B, n=14). In Bee Venom treated group(Group A), we treated patients with dry needle acupuncture and Bee Venom therapy. In Sweet Bee Venom treatred group(Group B), we treated patients with dry needle acupuncture and Sweet Bee Venom therapy. All process of treatment were performed by double blinding method. To estimate the efficacy of controlling pain. we checked Visual Analog Scale(VAS). For evaluating functional change of patients, Straight Leg Raising Test(S.L.R.T) was measured. Results 1. In controlling pain, Sweet Bee Venom treatred group(Group B) had similar ability in comparison with Bee Venom treated group(Group A). 2. In promoting function, Sweet Bee Venom treatred group(Group B) had similar ability in comparison with Bee Venom treated group(Group A). Conclusions It may be equal effects as compared with using Bee Venom to treat low back pain with radiation pain using Sweet Bee Venom. We can try to treat other disease known to have effect with Bee Venom.
