This study is basically about four-guardian-statutes-building-gate in 17th Century. In the field of art-history, there are four-guardian-statutes made of clay in order that the statutes are so gigantic and grotesque enough to threaten all the devils. This purpose of this study is to make sure that the similar variation occurred at the four-guardian-statutes-building-gate in 17th century. The results of this study are as follows. First, only Da-Po style four-guardian-statutes-building-gates were built in famous four temples separately from 1612 until the Manchu war of 1636. And there are gigantic four-guardian-statutes made of clay in the building. Second, there are Chul-mok Ik-gong style buildings were built in 1660s at Bo-Rim-Sa and Neung-Ga-Sa. The buildings including four-guardian-statutes-building-gate of Song-gwang-sa built in 1636 probably are all similar to earlier Da-Po style four-guardian-statutes-building-gates in the viewpoint of structural type and size of building. Third, it began to build Ik-gong style four-guardian-statutes-building-gates in 1676 at Su-ta-sa.

동영상 카메라와 보급형 망원경을 이용한 달과 행성의 관측

류성룡 한국물리학회 2015 새물리 Vol.65 No.3

The moon and the planets in our solar system are very close to the earth. They are bright enough to be observed with a small telescope, and they can be observed with high resolution; however, their images are easily disturbed by air turbulence. To catch “fortunate” frames, which are good images instantly frozen in 1/30th of a second, among disturbed images due to air turbulence, about oneminute high-resolution video images of the planets with about 30 frames per second (fps) were taken. RegiStax were used to select good frames, and the good frames were aligned and combined to make a single combined image. The combined images were also digitally processed to highlight hidden features. A monochromatic charged coupled device (CCD) camera with luminance, red, green, blue (LRGB) color filters were used to get high-resolution color images. High-resolution images of the moon and the planets were successfully obtained which could be used as educational materials in the classroom. 달과 행성은 태양계 내의 천체로서 우리에게 가장 가까운 천체들이고 아주 밝아서 중·고등학교에서 보급형 망원경으로 관측하기에 적합하다. 하지만 고배율 관측이 필요하여 대기의 흐름에 민감하므로 이를 적절하게 보정해 주어야 한다. 저자는 대기 흐름의 순간적인 변화를 고정하기 위하여 초당 30프레임 정도의 동영상 카메라를 이용하여 달과 행성의 고배율 동영상을 1분 정도 (1800 프레임) 찍었다. 천체용 동영상 처리 프로그램인 RegiStax를 이용하여 동영상에서 각 프레임을 분리하고 또렷한 프레임만을 골라 겹쳤으며, 겹쳐진 이미지는 최종적으로 디지털 처리하였다. 고해상도 컬러 이미지를 얻기 위하여 흑백 CCD 카메라와 LRGB 필터를 사용하여 색깔별로 따로 찍은 후에 나중에 합성하여 컬러 이미지를 얻었다. 이 논문에서 제시한 방법을 사용하여 교육적으로 사용하기에 적합한 고배율의 달과 행성 사진을 성공적으로 얻을 수 있었다.

음높이에 따른 첫 번째 포먼트와 성악 발성 전략과의 관계

류성룡 한국물리학회 2021 새물리 Vol.71 No.6

Sound from a person’s vocal cords is resonated through the vocal track. The spectrum of synthesized voices was analyzed for the /e/ vowels of male and female voices as the pitch goes up by using the singing synthesizer Madde. Vowel turn over is needed to maintain the vocal track shape of a given vowel at the intersection of the first formant F1 and 2f0 of a male voice, and F1 should track f0 when the female pitch reaches the normal F1 location. The weighted average of the harmonics contained in the F1 bandwidth was calculated and then used to explain the passive opening and closing of a vowel at the intersection of F1/2f0. The ratio of the first formant intensity relative to the total intensity of a voice was calculated, and the effect of changes in the ratio on the pharyngeal resonance in vocal vocalization and the migration of sensation of the sound were explained. 사람의 성대에서 발생한 목소리는 성도를 통하여 공명된다. 음성합성기 마데 (Madde) 를 사용하여음높이가 올라감에 따라 남성과 여성의 목소리의 /e/ 모음에 대하여 합성된 목소리의 스펙트럼을분석하였다. 남성의 첫 번째 포먼트 F1과 2f0 교차에서 주어진 모음의 성도 모양을 유지하는 모음전환의 필요성과 여성의 음높이가 보통의 F1에 도달하면 F1이 f0 을 추적해야 하는 이유를 설명하였다. F1 대역폭에 포함된 배음의 가중평균을 계산하여 F1/2f0 교차에서 모음의 수동적인 열림과 닫힘에대하여 설명하였다. 목소리의 세기에서 성도 공명의 첫 번째 포먼트가 차지하는 비율을 계산하였고 이러한 비율의 변화가 성악 발성에서 인두 공명에 미치는 영향과 감각지각적인 음의 배치에 대하여 설명하였다.

Objectives : The objective of this study was to research delayed growth with acupuncture and moxibustion treatment. Methods : We search the oriental medical literature related to delayed growth, especially loose skull(解顱), pigeon chest(龜胸), turtle back(龜背), five kinds of flaccidity(五軟), five kinds of retardations(五遲) and infantile malnutrition(疳證). Results : 1. Loose skull(解顱) is treated with moxibustion therapy of CV8(神厥) and two points(1.5 cm upper and under of CV8) 2. Pigeon chest(龜胸) is treated with moxibustion therapy of GB38(外丘), ST18(乳根) and 6 points around of ST17(乳中). 3. Turtle back(龜背) is treated with moxibustion therapy of BL13(肺兪), BL15(心兪) and BL17(膈兪) 4. Acupuncture therapy of five kinds of flaccidity(五軟) was rare. but there are one case to stimulate Hwatahyeopcheok point using plum-blossom needle. 5. Five kinds of retardations(五遲) is treated with moxibustion therapy of BL15(心兪) and two point of medial malleolus 6. Infantile malnutrition (疳證) is treated with acupuncture therapy of the spleen channel and stomach. channel, therapy using three-edged needle, cutting therapy(LU10(魚際) and Sabong), moxibustion therapy(LR13(章門) and BL21(胃兪)), and Ch’una therapy. Conclusion : We expect that acupuncture and moxibustion treatment of delayed growth will be applied practically in clinical medicine due to further study on delayed growth.

Objective : The aim of this study is to evaluate internal reliability and correlation among assessment instruments of knee OA. Methods : Data were obtained from 85 patients with knee OA. They were asked to answer VAS pain scale, two disease-specific questionnaires (WOMAC and LFI) and one instrument about health-related quality(KHAQ). Reliability was assessed using cronbach's alpha. Correlation was assessed by examining the pearson's correlation coefficients. Results : Cronbach's alpha of all Index except WOMAC stiffness subscale(.6679) exceeded the value of 0.70. A good correlation was obtained between WOMAC Subscale (especially Pain Subscale) and LFI (.726<cronbach's alpha<.791). Also, Correlation between KHAQ and two disease-specific questionnaires (WOMAC and LFI) was good(.612<cronbach's alpha<.662). Conclusions : All used instruments have good internal reliability. also, There are good correlation among them. The treatment of knee OA must be focused on health related quality. For this, we should use proper assessment instruments.

웹카메라를 이용한 천체사진촬영에 관한 연구

류성룡,황완기 금오공과대학교 2006 論文集 Vol.27 No.-

Recently, CCD cameras has been widely adoped for astronomical photography. CCD is more sensitive than photographic film and has the advantage of e,ISY digital image processing. In this paper, we have used a PC web camera instead of expensive commercial astronomical CCD camera for astrophotography. The images of the bright objects such as Moon, Sun, and Jupiter have been easily obtained by an ordinary web camera. A Vesta Pro web camera have been modified by Steve Chamber method for long exposed astrophotography. The thermal noise of the CCD has been dramatically decreased by cooling the CCD with a Peltier device. The initial images of the globular clusters M3 and M13 have been obtained with the modified Vesta Pro~SC web camera. We could obtain the bright pictures correspond to the long exposed photography by digitally adding the several short exposed frames. The noise of the long exposed frames were greatly reduced compared to the short exposed frames. In conclusion, we have shown that the web camera can be used for astrophography very economically in middle schools and high schools which have telescopes with limited tracking ability.

띠 모양의 에미터를 가지는 탄소나노튜브 삼전극 전계방출 디스플레이 소자의 시뮬레이션

The field emission characteristics are studied by simulation for carbon nanotube triode structures with a strip-shaped emitter and a gate hole aligned with it. Two structures, one with double-edge and the other with single edge are analyzed. They show good emission characteristics. Emissions of electrons are concentrated on the edges of emitter and the emitted current increases as the distance between emitter and gate decreases. For single-edged emitter, the emitted electrons form a narow strip-shaped beam which has a good directionality. These triode structures have advantages in that they can be easily fabricated and aligned for assembly.
