본 연구는 시각장애 특성에 따른 직업재활욕구를 고려하여 직업재활환 경을 설계하고 구현하기 위한 보편적인 방법론을 제시함으로써 시각장애인 관련 직업재활기관에서 시각장애인의 직업재활훈련을 확대․지원할 필요성 에서 시작하였다. 따라서 외국의 시각장애인을 위한 환경적 또는 직업적 지 원체계에 관한 문헌 및 매뉴얼 등을 수집, 조사, 검토하여 연구를 진행하였 다. 시각장애 특성에 부합하는 직업재활환경 설계의 기본 원칙은 첫째, 재활 장소의 구조와 배치를 직선형 동선으로 최대한 단순화하고, 둘째, 조명의 밝...

This study introduces how the asymmetry of item characteristic curves (ICC), a different change rate below versus above the inflection point of an S-shaped curve, functions more properly than other commonly used item response models in dealing with several measurement issues. Among asymmetric models, the logistic positive exponent (LPE) model of Samejima (2000) is focused on. This study mainly explores how asymmetric item response models can be extended to accommodate various psychometric...

Graphite fibers are materials with a high specific modulus that have attracted much interest in the aerospace industry, but their high manufacturing cost and low yield are still problems that prevent their wide applications in practice. This paper presents a laser-based process for graphitization of carbon fiber (CF) and explores the effect of laser radiation on the microstructure of CF. The obtained Raman spectra indicate that the outer surface of CF evolves from turbostratic structures into a...

Carboxylated multi-wall carbon nanotubes (MWCNTs-COOH) have been used as efficient adsorbents for the removal of picric acid from aqueous solutions under stirring and ultrasound conditions. Batch experiments were conducted to study the influence of the different parameters such as pH, amount of adsorbents, contact time and concentration of picric acid on the adsorption process. The kinetic data were fitted with pseudo-first order, pseudo-secondorder, Elovich and intra-particle diffusion models....
