a simple method to predict the neuronal cell death in the mouse hippocampus and striatum following transient global forebrain ischemia by evaluating both cerebral blood flow and the plasticity of the posterior communicating artery (PcomA). Male C57BL/6 mice were anesthetized with halothane and subjected to bilateral occlusion of the common carotid artery (BCCAO) for 30 min. The regional cerebral blood flow (rCBF) was measured by laser Doppler flowmetry. The plasticity of PcomA was visualized by...

reverse transcription- polymerase reaction/restriction enzyme (RTPCR/ RE) analysis-based method. We identified five REs, including DraI, EcoR1, NdeI/AseI, and SpeI, that could differentiate RSV RNA 1-4 subtypes, respectively. Our RT-PCR/RE results provided a clear pattern of RNA reassortment, i.e., different groups of isolates having their RNA segments derived from two to three different RSV ancestors, such as from Eastern and Southwestern Chinese or Japanese M and T isolates. We also found that...

to extend the multi-group latent profile approach proposed by Morin et al. (2016) to a multilevel context and to provide an illustration with real-world data. Specifically, multilevel multiple-group latent profile analysis (MMLPA) models were fitted following seven steps to classify students according to their perception of instructional practices in science classrooms and to compare the latent profiles of two countries using Korean and Japanese data from the Programme for International Student...

The purpose of this study was to develop a theory of students’ transition to college and to confirm that theory. To understand the nature and meaning of the first-year transition, a qualitative study was conducted using grounded theory, and a questionnaire was developed based on the established transition theory. The validation of the theory was analyzed through structural equation modeling (SEM), and a multi-group analysis was conducted to find out what differences existed in the structural...

a wet impregnation method. The effects of mass of kaolin support, pre-calcination time, pre-calcination temperature and stirring speed on catalyst yields are examined. Then, the optimal supported Fe-Ni catalyst is utilised to produce multi-walled carbon nanotubes (MWCNTs) using catalytic chemical vapour deposition (CCVD) method. The catalysts and MWCNTs prepared using the optimal conditions are characterized using high resolution transmission electron microscope (HRTEM), high-resolution scanning...

wide variety of genetic applications and is an efficient method for detection of mutations involving one or a few nucleotides. We developed a high-throughput DHPLC method for identifying polymorphisms in the MC1R gene that are characteristic of Hanwoo cattle. We compared 10 tissue samples from Hanwoo cattle, 10 samples from Holstein cattle and 10 samples from Hanwoox Holstein crossbred cattle to determine whether DHPLC analysis can be used to distinguish between these genotypes. Samples obtained...

대한 정량적인 값을 도출하였다. 영상 질(quality)의 주요변수인 MTF의 측정은 먼저 test pattern 영상을 획득한 다음, contrast method를 이용하여 공간주파수(spatial frequency)에서의 line profile을 디지털 값으로 획득하여 MTF를 계산하였다. 측정 결과, test pattern 영상에서 3.0 lp/mm에서 36.1%의 MTF 값을 나타냈으며, 종래의 필름 영상보다 약 2배 높은 해상력을 가짐을 알 수 있었다. 측정된 값은 비정질 셀레늄을 이용한 직접방식의 디지털 방사선 검출기의 임상적 사용가치가 충분함을 뒷받침 할 수 있는 기초 자료로서 제...
