주차장에서 일어날 수 있는 비매너 주차로 인한 충돌을 사전에 예방하기 위한 단속시스템이다. 주차장에서 일어날 수 있는 장애인, 전기차 전용 주차구역에 일반차량 주차, 2개 차선을 물고 주차하는 차량이 있다. 위와 같은 차량을 딥러닝 객체인식 기능을 통해 비매너 주차를 감지하여 알려준다. 비매너 주차 상황이 찍힌 사진이나 영상을 학습데이터로 사용하여 상황을 인식할 수 있도록 학습데이터를 제작하고 그 상황을 인식하여 비매너 주차 유무를 판단한다. 주차장의 환경을 좀 더 쾌적하게 함으로써 주차장 이용자간 충돌을 줄이는데 목적이 있다. It is a enforcement system to prevent collisions caused by unmanageable parking that may occur in parking lots. There are handicapped people who can get up in parking lots, general vehicles parked in electric vehicle parking areas, and vehicles parked in two lanes. The vehicle above is detected and notified through the deep learning object recognition function. By using a picture or video of an unmanageable parking situation as learning data, the learning data is produced so that the situation can be recognized, and the situation is recognized to determine the presence or absence of unmanageable parking. The purpose is to reduce collisions between parking lot users by making the environment of the parking lot more comfortable.

배경 : MRSA, VRE, VRSA같은 다제 내성 그람 양성균의 등장에 따라 glycopeptide를 대체할 새로운 항생제의 개발이 필요하게 되었고 결과적으로 새로운 항생제인 linezolid라는 항생제가 개발되었다. Linezolid는 이전의 항생제와는 다른 새로운 계열의 oxazolidinone으로 경구 이용률이 우수하다. 원내 및 원외감염의 중요한 원인균이 되고 있는 MRSA, VRE에 대한 적절한 경구용 항균제가 없는 국내에서 폐렴 및 피부 연조직 감염에서 경구용으로 사용해 볼 수 있는 약제이다. 본 연구에서는 고대 구로 병원에서 분리된 MRSA, VRE 등을 대상으로 다른 여러 항균제와 비교한 linezolid의 시험관내 항균력을 조사하고자 하였다. 재료 및 방법 : 연구대상은 1998년 1월부터 2000년 12월까지 본원에서 입원 및 외래를 통하여 피부 연조직 감염증 및 호흡기 감염증, 요로감염증으로 진단된 환자들의 가검물로부터 분리된 MRSA 60균주, VRE 43균주, PRSP 25균주를 액체배지 또는 한천배지 희석법을 통하여 linezolid 및 기타 항균제에 대한 최소발육억제농도를 구하였다. 결과 : 실험에 사용한 S. aureus는 모두 MRSA였고 이들은 linezolid에 대해 MIC_(90) 2㎍/㎖(MIC 범위 1-2㎍/㎖), Enterococcus spp는 모두 VRE로 linezolid의 MIC_(90)은 2㎍/㎖로 MIC 범위는 1-4㎍/㎖였다. 한 개의 균주에서 MIC 4㎍/㎖로 중등도 감수성을 보였으나 MIC breakpoint가 (8㎍/㎖인 내성균주는 없고 모두 감수성을 보였다. S. pneumoniae의 경우 penicillin 내성이었고, linezolid MIC_(90) 1㎍/㎖ (MIC 범위 0.5-1㎍/㎖)로 전부 감수성을 보였다. 결론 : Linezolid는 MRSA를 위시한 VRE, PRSP 등의 다제 내성 그람 양성균에 대하여 우수한 시험관내 항균력을 보임을 알 수 있었다. Background : The emergence of multi-drug resistant Gram-positive cocci, such as MRSA, VRE, and VRSA, necessitated to develop new antibiotics, which could replace the glycopeptide. As a result, a new antibiotics named linezolid was developed. Linezolid is different line of oxazolidinones with a good oral bioavailability, compared to other antibiotics. Since appropriate oral antibiotics are not presently available for MRSA, which is a major cause of nosocomial and community acquired infections, the introduction of linezolid will have favorable effect on treatment of infections such as pneumonia or skin infections. In this study, we investigated the antibiotic effect of linezolid on MRSA and VRE isolated from patients who were treated in Korea University Guro Hospital. Material and Methods : By using broth microdilution and agar dilution method we measured minimum inhibitory concentration (MIC) with sixty S. aureus, forty three Enterococcus spp., and twenty five S. pneumoniae isolates from patients who were diagnosed as skin, soft tissue, respiratory, and urinary infections in Korea University Guro Hospital from January, 1998 to December, 2002. Results : All of S. aureus used in this study were MRSA, and MIG_(90) of linezolid was below 2 ㎍/㎖ (MIC ranged between 1-2 ㎍/㎖). All of Enterococcus spp. were VRE, and had MIG_(90) of 2 ㎍/㎖ (MIC ranged between 1 to 4 ㎍/㎖). One of the VRE showed intermediate susceptibility with MIC of 4 ㎍/㎖. However, none was resistant with MIC breakpoint above 8 ㎍/㎖. All of S. pneumoniae were resistant to penicillin, but they were susceptible to linezolid with MICao of 1 ㎍/㎖(MIC range 0.5-1㎍/㎖). Conclusion : In conclusions, linezolid has an excellent in vitro antibiotic effect on multi-drug resistant Gram-positive cocci, such as MRSA, PRSP, and VRE.

본 원고는 2004년 과학사학자 박성래 교수가 독립 운동가이자 한국 근대 수학교육의 아버지로 부르기 시작한 보재 이상설(李相卨, 1870-1917)이 자연과학에 기여한 내용을 다루고 있다. 한국수학사학회지 2009년 11월 호에 자세히 소개된 〈數理〉를 쓴 시기를 전후하여, 같은 시기에 이상설이 붓으로 쓴 것으로 여겨지는 〈植物學>(이상설, 1899)은 총 4면의 초록 필사본이며, 그 대본(臺本)은 〈植物學啓蒙〉 (Edkins, 1886)으로 영국의 Joseph Edkins(艾約瑟, 1823-1905)가 번역하여 1886년에 간행한 〈西學啓蒙〉 16종 가운데 하나이다. 이상설의 〈植物學>은 이 〈植物學啓蒙〉을 읽으면서 그 책의 내용 중 당시의 조 선 학자가 모르고 있던 새로운 내용을 중심으로 메모를 한 것으로 여겨진다. 본 연구에서는 전통산학과 근대서양수학을 연결하는 〈數理〉를 저술했으며. 우리나라의 정규 교과과정에 수학과 과학을 필수과목으로 지정하고, 첫 번째 수학교과서 〈산術新書〉를 발간함으로 당대 최고의 수학자로 평가된 이상설이 쓴 〈植物學〉을 발굴하여 그 내용과 의미를 최초로 분석한다, 이를 통하여 당시 조선의 서양 과학, 특히 식물학에 대한 이해 수준을 분석하고 〈植物學〉의 원전인 〈植物學啓蒙〉 과 <西學啓蒙〉의 저자에 대하여 알아본다. 이는 당시 수학교육자가 자연과학분야에 행한 교육적 기여를 이해 하는데 필수적인 연구이다. This paper deals with contents that Sang-Seol Lee contributed to the natural science in the 19th century Korea. Prof. Sung-Rae Park, the science historian, called Sang-Seol Lee Father of the Modern Mathematics education of Korea. Sang-Seol Lee wrote a manuscript Botany with a brush in late 19th century. Botany was transcribed from Science Primers: Botany (written by J. D. Hooker), which is translated into Chinese by Joseph Edkins in 1886. The existence of Sang-Seol Lee`s book Botany was not known to Korean scientists before. In this paper, we study the contents of Botany and its original text. Also we analyze people`s level of understanding Western sciences, especially botany at that time. In addition, we study authors of 16 Primers for Western Knowledge. We study the contribution of mathematician Sang-Seol Lee to science education in the 19th century Korea.

Plate heat exchanger consists of thin, rectangular, pressed sheet metal plates that are sandwiched between full peripheral gaskets and clamped together in a frame. The frame has a fixed end-cover plate, fitted with the connecting ports, which is bolted together with a movable cover plate to hold the embossed plates in between; the top and bottom carrying bars allow proper alignment of the plate stacks. When compared with the well-established shell and tube heat exchangers, the plate heat exchanger shows a lot of advantages like high NTU values, compactness, low cost, multi duties and reduced fouling etc. Plate heat exchangers are often used to transfer heating or cooling water which is produced in the energy production( district heating or district cooling) facilities to residential areas and industrial parks. The district cooling systems of Middle East are the biggest market of plate heat exchanger, but the technical specifications for cooling system are different from the domestic one. To achieve its specifications, the new plate heat exchanger was developed, and its thermal performance results are introduced in this paper.

This paper presents a new method of converting 2-D video into 3-D stereoscopic video based upon the motion type of key frames. The proposed conversion method provides the stable display of 3-D stereoscopic depth. To realize this, we propose the concept of key frame that has the reliability of motion vector field(MVF) as well as the accuracy of estimated motion type. If a current frame does not belong to the key frame, its asscciated motion type follows the key frame. Therefore, the abrupt variation of the motion type can be avoided. As a result, the stereoscopic conversion can be smoothly varied between subsequent frames. Experimental results show that the stereoscopic conversion of any video can be shown in the stable manner.
