박찬영,정수현,김동찬,조종현 한국화학공학회 1990 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.28 No.2

구형의 γ-A1₂O₃에 산화동을 담지시킨 후 반응조건에 따라 아황산가스와 반응 흡착시켰다. 각 조건에서 산화동의 전화율을 측정하고 세공분포모델을 이용하여 CuO/γ-A1₂O₃와 아황산가스의 반응 흡착거동을 비교 분석하였다. 그 결과 초기 표면반응속도는 담지농도에 따라 변하지만 활성화에너지는 14.49kJ/㏖로 거의 일정하였으며 입자레이놀즈 수는 최종 전화율에 영향을 미치지 않았다. 또한 표면확산계수의 활성화에너지 값은 D_(es1) =1.82KJ/㏖, D_(es2), D_(es3)=5.37KJ/㏖로 세공영역에 따라 다르게 나타났다. 세공분포모델을 이용하여 산출한 전화율은 여러 반응조건에서 실험치에 근접하였으나 아황산가스 농도가 2,000ppm에서 3,000ppm으로 증가할 떼와 담지농도가 6wt%에서 8wt%로 증가할 때는 평형전화 상태에서 차이를 보였다. 최적 반응온도인 450℃ 이내에서는 실험치에 접근하였으나 그 이상의 온도범위에서는 큰 차이를 보였다. 반응온도 450℃, 담지농도 6wt%, 아황산가스 농도 2,000ppm에서 실제의 전화율은 63%로 최대치를 보였다. After impregnating copper oxide by using a spherical γ-A1₂O₃, CuO/γ-A1₂O₃ reacted with and/or adsorbed the sulfur dioxide on reaction conditions. Conversion of copper oxide was estimated under each condition and then the reaction and adsorption behavior between CuO/γ-A1₂O₃ and sulfur dioxide were analytically compared by using the distributed pore size model. From the results, it was shown that although the initial surface reaction rates varied with the impregnation concentration, the activation energy was constant as about 14.49KJ/㏖, and that the final conversion of CuO/γ-A1₂O₃ was not affected by the particle Reynolds number. Also the values of activation energy of surface diffusion coefficients were shown to be D_(es1) =5.39 KJ/㏖ and D_(es2), D_(es3) = 5.39 KJ/㏖ depending on the pore size region. Although conversion rates acquired by the analysis of distributed pore size model were close to the experimental values under most of reaction conditions, there were considerable deviations in the final conversion when the sulfur dioxide concentration changed from 2,000 to 3,000 ppm and the impregnation concentration increased from 6 to 8 wt%. Also below the optimum temperature of 450℃ the conversion rates based on the model were close to the experimental value, but over 450℃, there were considerable deviations between the two values. The maximum experimental conversion was shown to be 63% at 450℃ with 2.000 ppm of SO₂ on 6 wt% CuO/γ-A1₂O₃.

존재론적 진리에 대하여

박찬영 공주교육대학교 초등교육연구원 2011 敎育論叢 Vol.48 No.1

진리는 보통 인식진리와 존재진리, 즉 논리적 진리와 존재론적 진리로 나뉜다. 이 논문은 존재론적 진리의 의미를 밝히려는 노력의 시작이다. 우선 플라톤의 선의 이데아와 진리의 관계, 그 다음에 신플라톤주의의 정신(nous)=진리를 확인한다. 다음으 로 중세의 일반적인 진리정의인 `사물과 지성의 일치”의 통상적인 의미를 분석한 후에 안셀무스의 `정신으로만 파악 가능한 올바름”이라는 유명한 진리규정의 의미도 파헤쳐본다. 초월자 가운데 하나가 진(verum)이므로 이 진에 대해서도 살펴본다. 인 식진리와 구별되는 광의의 존재진리의 의미에서 실천적 진리, 종교적 진리도 언급된다. 끝으로 진리의 순수 우리말인 ‘참’은 ‘본질충족’임을 확인하고 참된 사람은 참 생명을 깨닫고 닮으려는 사람이며 불립문자의 자세에서 지행합일하고 무실역행하는 사람임을 강조한다.

The purpose of this study is to develop geostatistical methods for selection of prospective areas of polymetallic nodule deposits in KODOS (Korea Deep Ocean Study) area of the North-East Pacific Ocean. In this study $110{\times}165$ grid system was used, and each node represents the center of an estimated block of $1km{\times}1km$. The ordinary kriging was applied to SeaBeam2000 data in order to evaluate the bathymetry. A structural analysis (variogram) of the bathymetry data was carried out for constructing digital terrain model (DTM) and the maximum slopes of the bathymetry were calculated by DTM data. The above method can be used to solve the problem that is resulted from the lack of theory of a change of support model for the maximum slope of the bathymetry. The ordinary kriging and the indicator kriging were used to evaluate the nodule abundance, and the different two kriging methods were compared to evaluate the accuracy for the estimation of the nodule abundance. It has been shown that indicator kriging was better estimation tool than the ordinary kriging. The overlay map is presented for the selection of potentially minable sites by combining the two indicator maps of the nodule abundance and the maximum slope of bathymetry. This overlay map could be utilized to establish follow-up survey and to investigate the potentially minable sites in the KODOS area.

박찬영,문인혁 한국재활복지공학회 2008 재활복지공학회논문지 Vol.2 No.1

This paper proposes a data glove for a rehabilitation robot interface for the upper extremity paralysis. The designed data glove uses seven flexible sensors so as to measure the flexion angles of fingers and wrist. We verified the performance of the data glove using a 3D graphic interface developed. The experimental results show that the proposed data glove is feasible to sense hand motions and applicable to the robot interface.

박찬영,김민정,류기정,이원기 한국공업화학회 2014 한국공업화학회 연구논문 초록집 Vol.2014 No.1

polyester polyol과 acrylic polyol을 혼합 사용하여 PU 발포체를 제조한 후 물성을 측정하는 데 있어서 acrylic polyol 함량 변화에 따른 인장강도, 경도 및 인열강도 등의 기계적 성질에 미치는 영향을 검토하였다. 또한 acrylic polyol함량에 따른 FT-IR, 형태학적 변화 및 내가수분해성의 변화를 측정하여 이들 간의 상관관계를 규명하였다. 이러한 물성 이외에도 시차주사칼로리미터, 열중량분석, 동적기계적 분석장비 등을 이용하여 foam의 중요한 특성인 열적 성질을 측정하였다. 즉 DSC를 사용하여 acrylic polyol함량에 따른 Tg의 변화, TGA를 사용하여 acrylic polyol함량 변화에 따른 열안정성 검토 및 DMA를 사용하여 acrylic polyol함량 변화에 따른 저장탄성율과 tan δ 등의 물성을 검토하였다.

『黃帝內經』에 나타난 日月星辰에 關한 硏究

朴燦榮,金基郁,朴炫局 동국대학교 한의학연구소 1996 東國韓醫學硏究所論文集 Vol.5 No.-

A study on the effect of the Sun-Moon-Stars(日月星辰) in Huang Ti Nei Ching (「黃帝內經」)on the formation of the Yunqi theory(運氣理論) have revealed following conclusions. 1. There was a record of Stars(星辰) written by Gabgol-Character(甲骨文字) in the Yin(殷) Dynasty. But the very first documentary records of Stars(星辰) is Shu Jing(書經). Ancient astronomy had the tendency of astrology of combined with theory of the Five Elements(五行) and finally effects the theory of formation of Huang Ti Nei Ching (「黃帝內經」). 2. Shu Jing(書經) said that Junrak(「錢樂」) made an Armillary sphere(渾天錢) in the Sung()Dynasty. And in the Jin(秦) and the Han(漢) Dynasty they already observed the stars. The Sunkiokhyung(璿機玉衡) which is machinery of star-observing became to he called an Armillary sphere(渾天錢) by the pass of times. 3. As of the theory of the Cosines-structure(宇宙-構造論) in Ohanunhangdaeron(「五運行大論」),Guiyugu(鬼臾區) announced the Hypothesis of Covering Heaven(蓋天說) but Kibak(岐伯) supported the Hypothesis of chaosheven's(蓋天說) and in the theory of atmosphere(大氣論) in Ohanunhangdaeron(「 五運行大論 」) said that the earth was in Great Empty(太虛) and it was floating in the universe by the Great Chi(大氣). 4. The knowledge about the Five stars(五星) in Huang Ti Nei Chins(「黃帝內經」) is presented in the section of Gemgwejineonron「금궤진언론」), Gigoupyondaeron(「氣交變大論」), Youbuonjeonggidaeront「六元正紀大論」). In the method of identifying the Five stars(五星) presented the criteria of the brightness, the altitude, the colours and the orbit etc 5. The jupiter which has twelve year's revolution cycle was the basis of determination on the Twelve constellation(12辰), the Twelve field of heaven(12次), the Twelve Houses in the ecliptic(黃道12宮), the Twelve Earth's Branches(12支) and the Twelve fields of Earth(12分野) and also it became the origin of the duodecimals(12進法). 6. The saturn having about twenty-eight year's revolution cycle became the criterion in identifying the Twenty Eight Constellations(28宿) which was used as the coordinates of the Celestial sphere(天球). 7. By the Percussional movement(歲差運動), the position of polaris and the Vernal-Antumal equinox(春秋分点) were shifted. Therefore the ancient the Heaven Gate-Earth Door(天門-地戶)changed from the Position of Sil-Byuk(室壁), Yik-Jin(翼軫). And the precisional movements brought about the concept of the WunHoyYunSe(元會運世) that is a method of dividing a period. Also the precisional movement gave three dimension(三次元) foundation interpreted the Sixty JiaZi(六十甲子) which is revolving through sixty years uniformally. 8. The Hypothesis of the Nine Houses and Eight Winds(九宮八風論) which is one field of the astrology of ancient polaris-nine Houses divination plate(太一九宮占盤) brought about the concept of deficiency and excess and the concept of the Wind Vice(風邪). In the Calendar System(曆法) preaented in Huang Ti Nei Ching(「黃帝內經」) the tropical year of the Sun-Moon-Stars(日月星辰) and the revolution and the rotation of the earth give explanations the changes of Yin-Yang(陰陽) by the use of the ten Celestial branches(十干) and the twelve Earth blanches(十二支).
