The present study was performed to determine the accuracy and reproducibility of calculating the mitral regurgitant orifice area with the proximal isovelocity surface area (PISA) method in dogs with experimental mitral regurgitation and in canine patients with chronic mitral insufficiency and to evaluate the effect of general anesthesia on mitral regurgitation. Eight adult, Beagle dogs for experimental mitral regurgitation and 11 small breed dogs with spontaneous mitral regurgitation were used.... -

수 있다. BMLD는 신호에 대한 차폐된 탐지 역치가 signal과 masker의 상대적인 차이에 의해서 향상되는 것을 의미한다. BMLD는 비교적 미세한 크기차이(interaural difference cues of intensity, ILD)와 시간차이(interaural difference cues of time, ITD)를 처리하기 위한 청각시스템의 기능에 기인하는 것으로 알려져 있다. Goldstein은 청각시스템은‘phase deaf’는 아니며 제한된 범위 내에서 인지적으로 중요하게 작용한다고 제안했다.15) 이 phase는 소리의 변별에 중요한 요인으로 작용할 수 있다. 최근에는 복합음을 비롯한... -
The effect of the spinning conditions on the structure of mesophase pitch-based carbon fibers by Taguchi method
Zhao Jiang, Ting Ouyang, Xiangdong Yao, Youqing Fei 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 11 89-98 (10 pages)
Taguchi’s experimental design was employed in the melt spinning of molten mesophase pitch to produce carbon fibers. The textures of the obtained carbon fibers were radial with varied crack angles, as observed by scanning electron microscopy and polarized optical imaging. The diameter, crack angle, preferred orientation, and tensile modulus of the produced samples were examined to investigate the influence of four spinning variables. The relative importance of the variables has been emphasized... -

대규모 DC 전력시스템에서는 회로차단기와 계전기로 대표되는 기존의 전자기적 회로 차단기가 산업 전 분야에 널리 이용되고 있다. 최근에는 고 신뢰성, 원격제어능력, 과부화와 단락전류 보호, 적은 열손실 등의 장점을 가지고 있는 원격전력제어기를 MOSFET 반도체 스위칭 소자를 이용하여 개발하고 있는 추세이다. 따라서 원격전력제어기는 고품질을 요구하는 시스템에서 필수적인 부품이 되어가고 있다. 본 논문에서는 원격전력제어장치를 모델링하였고 DSP를 이용하여 과전류 여부를 미리 판단할 수 있는 테스트 환경을 구현하여... -
Determination of Roxithromycin by Liquid Chromatography/ Mass Spectrometry after Multiple-Dose Oral Administration in Broilers
Jong-hwan Lim, Byung-kwon Park, Hyo-in Yun 대한수의학회 Journal of Veterinary Science 5 Pages
대한수의학회 Journal of Veterinary Science 2003, 제 4권 제 1호 6 35-39 (5 pages)
A highly sensitive and specific method for the determination of roxithromycin in broiler tissues by LC/MS was developed and validated. A dichloromethane extract of the sample was separated on C18 reversed-phase column with acetonitrile-50 mM ammonium acetate (80:20, v/v) as the mobile phase and analyzed by LC/MS via atmospheric pressure ionization/electrospray ionization interface. The limit of detection and limit of quantitation were 1 ng/g and 5 ng/g. The method has been successfully applied... -
A Simple Dosing Scheme for Intravenous Busulfan Based on Retrospective Population Pharmacokinetic Analysis in Korean Patients

Busulfan is an antineoplastic agent with a narrow therapeutic window. A post-hoc population pharmacokinetic analysis of a prospective randomized trial for comparison of four-times daily versus once-daily intravenous busulfan was carried out to search for predictive factors of intravenous busulfan (iBu) pharmacokinetics (PK). In this study the population PK of iBu was characterized to provide suitable dosing recommendations. Patients were randomized to receive iBu, either as 0.8 mg/kg every 6 h... -
Development of Luciferase Reporter Gene-based Cell Bioassay for the Aromatic Hydrocarbon Receptor Agonists

The aromatic hydrocarbon receptor (AhR) is a ligand-activated transcription factor that mediates many of the biological and toxicological effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, dioxin) and related chemicals. The application of recombinant reporter plasmid such as the firefly luciferase gene has proven to be a very effective method to detect these chemicals. The bioassay system, CALUX, is sensitive in directly detecting AhR-agonists from a variety of environmental and biologic...
