셰익스피어의 극 언어, 어떻게 한국화 할 것인가?

이현우(Hyon-u Lee) 한국셰익스피어학회 2015 셰익스피어 비평 Vol.51 No.1

Shakespearean characters would say “hear a play” instead of “see a play.” Hearing is as important as seeing in Shakespearean plays. It is, of course, because Shakespeare’s language, represented by blank verses, couplets, sharing lines, and puns, plays essential parts in his plays. Incidentally, when Shakespearean plays are translated or performed in Korean, those poetic and dramatic qualities of Shakespearean language are usually ignored. As the linguistic structures and the poetic systems of Korean language are quite different from those of English, most of Korean Shakespeare translations and stage productions have used simple prose translations without such poetic and dramatic qualities so far. However, some Shakespearean scholars including Choi Jong-cheol and myself have tried to do poetic translations. Especially some Shakespearean productions such as Oh Tae-suk’s Romeo and Juliet, Macbeth, and The Tempest, Park Sung-hwan’s Changgeuk Romeo and Juliet, Park Sun-hee’s Pansori Hamlet Project have used Korean poetic language, and shown how Korean poetic rhythms can alternate Shakespearean poetic language.

이현우,임종명,이훈,박지영,장미,이진홍,Lee, Hyeon-Woo,Lim, Jong-Myoung,Lee, Hoon,Park, Ji-Young,Jang, Mee,Lee, Jin-Hong 한국분석과학회 2018 분석과학 Vol.31 No.4

국내에서는 많은 수의 친환경 및 건강 증진을 목적으로 하는 기능성 생활제품이 생산되고 있으며 이러한 제품 제조 시 원료물질에 존재하는 모나자이트, 토르말린 등 방사능 농도가 높은 물질이 가공제품 내에 함께 유입 될 수 있어 원료물질과 함께 국민 생활과 밀접한 가공제품의 관리가 필수적이다. 이를 위해서 정확한 방사능 농도 분석 자료 및 유효성이 검증된 분석방법의 이용 및 개발이 필수적이다. 본 연구에서는 천연방사성 물질의 신속 스크리닝을 위한 ED-XRF 분석법과 정밀분석의 목적으로 ICP-MS를 이용하여 실내 건축자재 및 생활제품 내의 천연방사성핵종($^{238}U$, $^{232}Th$)의 농도를 정량분석하고 비교 및 평가하였다. 타일, 시멘트, 페인트, 벽지, 석고보드 등 총 47 종의 실내 건축자재와 건강제품, 섬유제품, 광물질 등 총 47 종의 생활 가공제품의 실제시료를 분석한 결과, ED-XRF 및 ICP-MS의 결과값은 전체적으로 1:1의 선형성을 보였으며 ED-XRF를 이용한 신속 스크리닝의 적용성과 ICP-MS를 이용한 정량분석법의 유효성을 확인하였다. 한편, 가공제품 중의 $^{238}U$, $^{232}Th$ 방사능 농도는 생활제품에 비해서 건축자재에서 상대적으로 매우 낮은 수준이었으며 특히 생활제품은 47 개 중 6 개의 제품이 원료물질의 관리기준치($1.0Bq{\cdot}g^{-1}$)를 초과(최대 $8.2Bq{\cdot}g^{-1}$)하는 것으로 평가되었다. A large number of functional living products are being produced for eco-friendly or health-promoting purposes. In the manufacturing process, such products could be adulterated with raw materials with high radioactivity, such as monazite and tourmaline. Thus, it is essential to manage raw materials and products closely related to the public living. For proper management, an accurate radioactivity data of the processed products are needed. Therefore, it is essential to develop a rapid and validated analytical method. In this study, the concentration of the radioactive $^{238}U$ and $^{232}Th$ in building materials (e.g., tile, cement, paint, wall paper, and gypsum board) and living products (e.g., health products, textiles, and minerals) were determined and compared by ED-XRF and ICP-MS. By comparing the results of both methods, we confirmed the applicability of the rapid screening and precise analysis of ED-XRF and ICP-MS. In addition, $^{238}U$ and $^{232}Th$ levels were relatively lower in building materials than in living products. Particularly, $^{232}Th$ content in 6 of 47 living products exceeded (maximum $8.2Bq{\cdot}g^{-1}$) the standard limit of $^{232}Th$ content in raw material ($1.0Bq{\cdot}g^{-1}$).

본 논문에서는 사람의 생체 신호를 감지하기 위해 1.6 GHz 단일 채널 도플러 센서와 아날로그 및 디지털 신호 처리부로 구성되어 있는 실시간 호흡 및 심장 박동 감지기를 개발하였다. 도플러 센서의 RF Front End는 발진기, 믹서, 저잡음 증폭기, 브랜치-라인 하이브리드, 그리고 패치 안테나로 구성되어 있다. 센서에 사용된 브랜치-라인 하이브리드는 기존의 하이브리드에 비해 40 % 정도 크기를 줄이면서도 상당히 유사한 성능을 가지도록 인공 전송 선로(artificial transmission line)를 사용하였다. 아날로그 신호처리부는 2차 Sallen-Key 능동 필터를 사용하여 제작되었고 디지털 신호 처리부는 LabVIEW를 사용하여 컴퓨터상에서 구현되었다. 개발된 시스템은 최대 50 cm 거리에서 사람의 호흡과 심장 박동을 측정함으로써 성능을 검증하였다. This paper presents a real-time respiration and heartbeat detector comprised of a 1.6 GHz single-channel Doppler sensor and analog/digital signal processing block for remote vital sign detection. The RF front end of the Doppler sensor consists of an oscillator, mixer, low noise amplifier, branch-line hybrid and patch antenna. We apply artificial transmission lines(ATLs) to the branch-line hybrid, which leads to a size reduction of 40 % in the hybrid, while its performance is very comparable to that of a conventional hybrid. The analog signal conditioning block is implemented using second order Sallen-Key active filters and the digital signal processing block is realized with a LabVIEW program on a computer. The respiration and heartbeat detection is demonstrated at a distance of 50 cm using the developed system.

In summer, the natural ventilation performance for varying greenhouse width is very important in the glasshouses for year round cultivation. The effect of the side openings and greenhouse width on natural ventilation performance was analyzed by simulation. The necessary ventilation rate with different solar radiation transmittance increased significantly when the outside temperature grows higher. The necessary ventilation rate of 40% transmittance was about half of that of 90% transmittance. In consequence, shading effect on temperature control in greenhouse is significant in summer. When the total area of the openings for ventilation is constant, the maximum ventilation rate happens when the area of roof openings is equal to the area of side openings. This maximum ventilation rate is about 3 times of that of the greenhouse with roof openings and without side openings. Therefore, the side openings are advantageous to improve the natural ventilation in greenhouses. As the greenhouse width increases, the influence of side openings on the ventilation rate is becoming smaller. If the natural ventilation rate of the greenhouse with roof and side openings is to become double of that of the roof openings only, the width should be narrower than 38.4m for the Venlo type and 64m for Wide span type.

The purpose of the present study is to determine an optimum composition using cheaper powders keeping with high performance of hard rock cutting diamond saw blade. With 50Fe-20(Cu . Sn)-30Co specimen, a part of Co was replaced by Ni(5%, 10%, and 15%, respectively). These specimens were hot pressed and sintered for predetermined time at various temperature. Sintering is performed by two different methods of temperature controlled method and specimen dimension controlled method. In order to determine the property of the sintered diamond saw blade, 3 point bending tester, X-ray diffractometer, and SEM were used. As the Co in the bond alloy was replaced by Ni, the hardness of the specimen increased. Thus the 50Fe-20(CuㆍSn)-15Co-15Ni specimen showed the maximum hardness of 104(HRB). The results of 3 point bending test showed that flexure strength decreased along with increase in Ni content. This is attributed to the formation of intermetallic compound(Ni$_{x}$Sn) determined by X-ray diffraction. The fracture surface after 3 point bending test showed that diamond was fractured in the specimen containing 0%, 5%, and 10%Ni, and the fracture occurred at the interface between diamond and matrix in the specimen containing 15%Ni. The cutting ability test showed that the abrasive property was not changed in the specimen containing 0%, 5%, and 10%Ni. The optimum composition determined in this study is 50Fe-20(CuㆍSn)-20Co-10Ni.

This study proposes a $CO_2$ emission reduction method through correlation analysis of a sample building. First, energy saving factors of heating, cooling, lighting were determined for the correlation analysis and $CO_2$ emission contribution rate of the design parameters have been analyzed. Then optimal combination of each design parameter has been drawn. Heat transfer coefficient of walls and windows, air permeability, windows area ratio, and shading devices were selected as applicable energy saving factors of the sample building. Also computer simulation was conducted using experimental design by Orthogonal Arrays of the statistical method. And the contribution rate was estimated by Analysis of Variance-ANOVA. As a result, the $CO_2$ emission in heating was reduced to 51.9%; in cooling to 16.8%; and in lighting to 2% compared to the existing building. The majority of the reduction was presented by heating energy.
