Our objective was to evaluate the effectiveness of skin-stretching devices for closing defects on the extremities of dogs. Antebrachial skin defects were created on the limbs of 24 dogs randomly divided into three groups. Skin stretchers included staples and sutures passing through them (group A), sutures and hypodermic needles (group B), and Pavletic device (group C). Wounds on the left were further undermined in all groups. Tension and blood perfusion were assessed.... -
사범대에서 가르치는 교육학 이론의 현장 유용성 부족에 대한 고찰

한국교원교육학회 한국교원교육연구 2013, 제 30권 제 2호 4 77-97 (21 pages)
본 연구는 사범대에서 가르치는 교육학 이론이 교사에게 유용하지 못하다고 할 때, 이의 다양한 의미를 고찰하고 그 근본적인 원인을 살펴보는 데 목적이 있다. 교육학 이론이 실제 에 유용하지 못하다고 할 때 첫 번째는 이론이 실제와의 연관성이 부족한 경우로, 이는 이론 과 교사업무와의 연관성, 이론과 교실 맥락과의 연관성, 그리고 교사와 학자간의 인식론적 연 관성의 세 가지 측면에서 논의되었다. 둘째, 교육학 이론이 실제에 구체적 처방을 주지 못할 때 이는 실제에 유용하지 못하다는 평가를 받기 쉽다. 교육학 이론이... -

Can Advertising Survive the Information Technology Revolution? : An Exploratory Essay on the Future of Advertising
Tae-Il Yoon 한국광고PR실학회 광고PR실학연구 15 Pages
한국광고PR실학회 광고PR실학연구 2009, 제 2권 2호 2 32-46 (15 pages)
Advertising flourished during the previous century so much that Advertising Age called the twentieth century “the advertising century” when they published a special issue looking back at 100 years of advertising. However, can advertising continue to flourish in this twenty-first century? If we concern the long-term future of advertising as a social institution rather than a short-term advertising industry, the prediction might not be so simple. To answer this ontological question, this essay... -
The impact fracture behaviors of CFRP/EVA composites by drop-weight impact test

A drop weight impact test was conducted in this study to analyze the mechanical and thermal properties caused by the changes in the ratio of carbon fiber reinforced plastic (CFRP) to ethylene vinyl acetate (EVA) laminations. The ratios of CFRP to EVA were changed from 10:0 (pure CFRP) to 9:1, 8:2, 6:4, and 5:5 by manufacturing five different types of samples, and at the same time, the mechanical/thermal properties were analyzed with thermo-graphic images. As the ratio of the CFRP lamination was... -

In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist... -
Method and mechanism of dispersing agent free dispersion of short carbon fibers in silicon carbide powder
Thakur Sudesh Kumar Raunija, Mariamma Mathew, Sharad Chandra Sharma 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.3 4 180-186 (7 pages)
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...
