본 연구는 비판적 사고를 능력 차원과 성향 차원으로 나누고 이들의 관계를 검토하여 비판적 사고 교육에의 시사점을 얻고, 비판적 사고 능력 및 성향과 학업성취 및 인성과의 관계를 확인하여 비판적 사고의 예언변인이나 결정변인으로서 학업성취와 인성이 적합한 가를 검토하고자 한다. 이를 위하여 미국 일리노이 수학․과학 영재 고등학교 신입생 113명을 대상으로 비판적 사고 능력 및 성향, 학업성적과 인성을 측정한 자료를 분석하였다. 그 결과 첫째, 비판적 사고 능력은 비판적 사고 성향과 관련이 없었다. 따라서 비판적...

무용치료는 신체의 동작으로 내부의 감정 상태를 반영시켜, 자기탐구와 자기표현, 정직한 의사소통과 긍정적인 상호작용이 일어나게 하므로 가족 무용치료과정에서 가족 구성원들의 정서적, 감정적 장애요소들을 효과적인 의사소통으로 이끈다. 가족은 각 가정마다 고유한 특성을 지니고 있고 나름대로의 규칙, 역할, 세력, 구조, 의사소통의 유형을 발전시켜 온 하나의 사회체계이다. 가족은 강력한 구조로 조직되고, 복잡하고 은밀하고 감춰진 형태의 의사소통을 발전시킨다(Goldenberg&Goldenberg,2004:3). 그러므로 인간의 문제는...

Carbon-based magnetic nanostructures in several instances have resulted in improved physicochemical and catalytic properties when compared to multi-wall carbon nanotubes (MWCNTs) and magnetic nanoparticles. In this study, magnetic MWCNTs with a structure of NixZnxFe2O4/MWCNT as peroxidase mimics were fabricated by the one-pot hydrothermal method. The structure, composition and morphology of the nanocomposites were characterized with X-ray diffraction (XRD), Fourier transform infrared...

In this study, composite PAN-based ACNFs embedded with MgO and MnO2 were prepared by the electrospinning method. The resultant pristine ACNFs, ACNF/MgO and ACNF/MnO2 were characterized in terms of their morphological changes, SSA, crystallinity and functional group with FESEM-EDX, the BET method, XRD and FTIR analysis, respectively. Results from this study showed that the SSA of the ACNF/MgO composite (1893 m2 g?1) is significantly higher than that of the pristine ACNFs and ACNF/MnO2 which is...

Polycrystalline diamond (PCD) tools possessing high hardness and abrasive wear resistance are particularly suited for drilling of carbon fiber reinforced plastic (CFRP) composites, where tool life and consistent hole quality are important. While PCD presents superior performance when drilling CFRP, it is unclear how it performs when drilling multi-stack materials such as CFRP-titanium (Ti) stacks. This comparative study aims to investigate drilling of a Ti plate stacked on a CFRP panel when...

In the present study, biomass-based lignin was extracted from industrial waste black liquor and the extracted lignin was characterized by means of attenuated total reflectance- Fourier transform infrared spectroscopy and 1H-nuclear magnetic resonance spectroscopy. The extracted lignin was carbonized at different temperatures and then activated with steam at 850oC. The extracted lignin in powder state was transformed into a bulky carbonized lignin due to possible fusion between the lignin...

Carbon fiber reinforced polymer (CFRP) composites have been used for many decades for extreme light weight design purposes in various areas, such as the aerospace industry, automobiles, sports goods and etc. because they provide the advantages of high specific strength and high rigidity [1]. In particular, the fuselage and wings of various aircraft, as well as the load bearing structures and components of mechanical and civil engineering systems are currently being manufactured with CFRP....

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....

The objective of this study is the removal of chromium from tannery wastewater by electrosorption on carbon prepared from lignocellulosic natural residue "peach stones' thermally treated. The followed steps for obtaining coal in chronological order were: cleaning, drying, crushing and finally its carbonization at 900°C. The characterization of the carbon material resulted in properties comparable to those of many coals industrially manufactured. The study of the dynamic adsorption of chromium...

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...
