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 기술은 각종 산업시설과 환경 기초 시설로부터 대기중으로 배출되는 악취 및 휘발성 유기화합물(Volatile Organic Chemicals; VOC)을 미생물의 분해 작용을 활용하여 제거하는 장치로 오염 물질의 분해과정에서 미생물의 과다생장에 의한 악취 및 휘발성 유기화합물 제거장치의 막힘현상을 미생물 고정화 담체의 교반과 살수과정을 통해 담체표면의 생물막을 효과적으로 제거하는 방법을 이용하여 오염 가스속에 함유되어 있는 악취 및 휘발성 유기화합물을 효율적으로 제거할 수 있는 기술이다. 특히, 미생물 담체의 교반 장치는 미생물 고정화 담체를 교반시켜 생물막을 탈리 시킴으로써 미생물의 생장에 의한 막힘 현상과 이로 인한 압력 손실 증가와 악취 및 휘발성 유기화합물의 제거성능의 저하를 근본적으로 해결할 수 있다.

65 nm급 게이트 유전체로의 $HfO_2$의 적용을 위해 hydrogen-terminate된 Si 기판과 ECR $N_2$ plasma를 이용하여 SiNx를 형성한 기판 위에 MOCVD를 이용하여 $HfO_2$를 증착하였다. $450^{\circ}C$에서 증착시킨 박막의 경우 낮은 carbon 불순물을 가지며 비정질 matrix에 국부적인 결정화와 가장 적은 계면층이 형성되었으며 이 계면층은 Hf-silicate임을 알 수 있었다. 또한 $900^{\circ}C$, 30초간 $N_2$분위기에서 RTA 결과 $HfO_2/Si$의 single layer capacitor의 경우 계면층의 증가로 인해 EOT가 열처리전(2.6nm)보다 약 1 nm 증가하였다. 그러나 $HfO_2/SiNx/Si$ stack capacitor의 경우 SiNx 계면층은 열처리후에도 일정하게 유지되었으며 $HfO_2$ 박막의 결정화로 열처리전(2.7nm)보다 0.3nm의 EOT 감소를 나타내었으며 열처리후에도 $4.8{\times}10^{-6}A/cm^2$의 매우 우수한 누설전류 특성을 가짐을 알 수 있었다. Hafnium-oxide gate dielectric films deposited by a metal organic chemical vapor deposition technique on a $N_2-plasma$ treated SiNx and a hydrogen-terminated Si substrate have been investigated. In the case of $HfO_2$ film deposited on a hydrogen-terminated Si substrate, suppressed crystallization with effective carbon impurity reduction was obtained at $450^{\circ}C$. X-ray photoelectron spectroscopy indicated that the interface layer was Hf-silicate rather than phase separated Hf-silicide and silicon oxide structure. Capacitance-voltage measurements show equivalent oxide thickness of about 2.6nm for a 5.0 nm $HfO_2/Si$ single layer capacitor and of about 2.7 nm for a 5.7 nm $HfO_2/SiNx/Si$ stack capacitor. TEM shows that the interface of the stack capacitor is stable up to $900^{\circ}C$ for 30 sec.

Objective : The effects of Indium-Gallium-Aluminium-Phosphide(InGaAlP) laser transcutaneous irradiation on heart rate variability(HRV) in healthy adults are investigated with power spectrum analysis(PSA) of HRV. Methods : The control group consisted of 20 healthy volunteers (10 men, 10 women). The experiment was divided into 5 different periods, the pre-1st laser period(10 minutes), the 1st laser period(30 minutes), the post-1st laser period(5 minutes), the 2nd laser period( 30 minutes) and the post-2nd laser period(30 minutes). HRV was measured for 5 minutes at the pre-1 st laser period, the post-l st laser period and the post-2nd laser period. The laser period is the period in which InGaAlP laser transcutaneous Irradiation treatment occurs. Results : 1. SDNN of volunteers at post-1st laser period and post-2nd laser period significantly increased compared with that of the pre- 1 st laser period. 2, Ln(VLF) at post-I st laser period significantly increased compared with that of pre-1st laser period, while Ln(HF) at post-2nd laser period significantly decreased compared with those of pre- I st laser period and post-1st laser period, 3. Ln(TP) at post-1st laser period and post-2nd laser period significantly increased compared with that of pre-1st laser period, 4, LF/HF Ratio at post-2nd laser period significantly increased compared with those of pre-1st laser period and post-1st laser period. But the other variables did not significantly change. Conclusions : The results suggest that InGaAlp laser transcutaneous Irradiation in healthy adults is associated with the autonomic nervous systems. Further study is needed for investigating the effects of laser irradiation on autonomic nervous systems.

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.

이스라엘의 관점에서 본 소련 전차

이태호,Lee, Tae-Ho 한국방위산업진흥회 1989 國防과 技術 Vol.- No.121

소련이 운용하는 전차 모델은 아직까지 중동지역국가의 중요한 장비인 T-55 및 T-62와 반고정(Semi-fixed)탄을 사격하는 125미리 활강포를 장착한 T-64와 T-72, 그리고 새로운 T-80등 5가지이다. 전차전에서 이스라엘군의 경험이 인간공학적 측면등 소련 전차설계의 결점을 확인시켜 주었지만, 원칙적으로 소련 전차는 전투지향적이고 야전조건에 생존력이 있는 우수한 장비이다. 만약 고도로 훈련된 승무원에 의해서 운용된다면 가장 위험하고 치명적인 상대가 될수 있는 것이다
