The purpose of this study is to obtain the effective concentration of capsaicin to relieve pain with no change in the number of C-fibers and its effective duration for pain relief. Capsaicin has been used extremely as a experimental tool and as topical medications for acute or chronic tissue injuries and partial nerve injury is the main cause of causalgiform pain disorders in humans. Here, the left sciatic nerve was ligated unilaterally at the high level of the thigh to prepare an animal model...

The elevation of the floor of the maxillary sinus with an autogenous bone graft in a severely resorbed edentulous maxilla is a generally accepted pre-implantology procedure to enable successful placement of endosseous implants in an optimal prosthetic position1). An often mentioned drawback of this procedure is the development of maxillary sinusitis after augmentation2). The clinical diagnosis of sinusitis is characterized by a typical triad of symptoms, i.e. nasal congestion, pathological...

세계경제는 혁신, 창의력, 기업가 정신을 자극하는 귀중한 자원으로 지식을 활용하는 새로운 경제 모델을 필요로 한다. 생산성과 경쟁력을 강화함으로써 지속가능한 성장을 통한 사회복지를 실현할 수 있기 때문이다. 정책 입안자는 지식경제의 영역을 고려하여 생산성과 경쟁력 관련 새로운 공공정책을 수립하고 지식의 관점에서 개발정책을 관리할 수 있는 제도적 역량을 확립해야 한다. 지식경제피라미드(Knowledge Economy Pyramid) 모델은 교육, 연구, 기술, 비즈니스, 혁신, 정부 및 지역사회의 지식 생태계에 촉매 역할을 하며...

This study builds on economic and sociological perspectives and investigates how forms of capital (i.e., economic, cultural, and social capital) and habitus shape the college-choice process. Using the Education Longitudinal Study (ELS:2002), this study utilizes multinomial logistic regression with fixed effects. The findings indicate that differences exist in how the various forms of capital and proxies for habitus are associated with college choice. The results further reveal distinctly...

This paper discusses differences between two popular curriculum approaches in early childhood education: the Project Approach developed in the United States and the Reggio Emilia Approach developed in Italy. Although they are similar in many ways, their differences are mainly due to their divergence in focus on domains of learning: one on science and social science, the other on art. In turn, differences in epistemology, ontology, the purpose of education, the learning process, and types of...

Multi-walled carbon nanotube (MWCNT)/polycarbonate (PC) nanocomposite was prepared by direct melt mixing to investigate the effect of the shear rate on the surface resistivity of the nanocomposites. In this study, an experiment was carried out to observe the shear induced orientation of the MWCNT in the polymer matrix using a very simple melt flow indexer with various loads. The compression-molded, should be eliminated. MWCNT/PC nanocomposite sample exhibited lower percolation thresholds (at 0.8...

In this work, thermal treatment accompanied with different acid treatments was applied to a commercial coal tar pitch (CTP) to obtain a spinnable precursor pitch for carbon fiber. In the case of thermal treatment only, a relatively high reaction temperature of between 380°C and 400°C was required to obtain a softening point (SP) range of 220°C-260°C and many meso-phase particles were created during the application of high reaction temperature. When nitric acid or sulfuric acid treatment was...

This study highlights a novel method and mechanism for the rapid and effective milling of carbon fibers (CFs) in silicon carbide (SiC) powder, and also the dispersion of CFs in SiC powder. The composite powders were prepared by chopping and exfoliation of CFs, and ball milling of CFs and SiC powder in isopropyl alcohol. A wide range of CFs loading, from 10 to 50 vol%, was studied. The milling of CFs and SiC powder was checked by measuring the average particle size of the composite powders. The...
