본 연구의 목적은 Mead의 상징적 상호작용론에 대한 이론 체계를 조망하여 상징적 상호작용의 작동 기제를 거울뉴런이 어떻게 그 근거를 제공하는지 고찰하고 또한 거울뉴론의 의미를 분석하여 교육학적 적용과 활용 가능성을 탐구하는 것에 있다. 상징적 상호작용론은 연구의 초점을 학교의 실제 생활에 위치시키며 학교에서 일어나는 명시적 혹은 묵시적 상호작용과 실천에 대한 이해 제고에 이바지하였다. 그러나 Mead 이론에서는 어떻게 정신, 자아, 사회가 사회적 상호작용을 바탕으로 출현하고 유지되는지에 대한 경험적 근거가...

The anchoring vignette method is a popular method for correcting response bias in Likert-type measurements. It is a technique of correcting an individual s response to a measurement item by using the responses to vignette items on the same variable. However, out of ways one can adjust respondents’ scores using anchoring vignettes, comparisons across different methods of score adjustment have been insufficiently discussed. Hence, this study analyzed and compared the correction effects of...

본 연구에서는 2009 개정 교육과정에 따른 교과 교육과정에서 ‘성취기준’의 실태와 문제점을 분석 하고 외국 교육과정 문서 분석과 델파이 조사 결과에 기반하여 그에 따른 개선 방안을 마련하고자 하 였다. 연구 결과, 본 연구에서는 교과 교육과정 문서의 내부적인 측면으로 ‘성취기준’이라는 용어가 남 용되고 있으며 학습 내용 성취기준에서 ‘내용’과 ‘수행’의 기술 방식이 형식적으로 고정화되어 있는 문 제를 제기하였고, 교과 교육과정 문서의 외부적인 측면으로 평가기준으로서의 성취기준이 국가 교육과 정 문서와는...

We studied the basic properties and fabrication of reduced graphene oxide (rGO) prepared using eco-friendly reduction agents in the graphene solution process. Hydrazine is generally used to reduce graphene oxide (GO), which results in polluting emissions as well as fixed nitrogen functional groups on different defects in the graphene sheets. To replace hydrazine, we developed eco-friendly reduction agents with similar or better reducing properties, and selected of them for further analysis. In...

Activated carbons (ACs) have been used as electrode materials of electric double-layer capacitors (EDLC) due to their high specific surface areas (SSA), stability, and ecological advantages. In order to make high-energy-density ACs for EDLC, petroleum pitch (PP) precarbonized at 500?1000°C in N2 gas for 1 h was used as the electrode material of the EDLC after KOH activation. As the pre-carbonization temperature increased, the SSA, pore volume and gravimetric capacitance tended to decrease, but...

Phenomena related to global warming have been of particular interest among researchers, strongly encouraging them to identify various methods of adsorbing contributing gases, such as CH4 and CO2 [1,2]. Many adsorbents have been widely proposed and studied to remove greenhouse gases from the atmosphere and protect the environment [3,4]. Carbon-based materials for adsorption are an intriguing subject owing to their very high specific surface area, low weight, and elasticity [5,6]. Among various...

Carbon rich fly ash was recently reported to have compositions that are ideal for use as a precursor and catalyst for carbon nanotube growth. This fly ash powder is mostly composed of pure carbon, predominantly present as sp2. In this work, the effect of sonication time on the morphology and structural properties of carbon rich fly ash particles is reported. The obtained results show that ultrasound treatment is an effective tool for producing ultrafine particles/fragments with higher porosity,...

and the attached 4-hydroxyquinazoline. The toxicity of the samples was evaluated in human embryonic kidney HEK293 and human breast cancer SKBR3 cell lines, and the viable cell numbers were measured by 3-(4,5-dimethyl- 2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) after the cells were cultured for 24 h. Cellular investigations showed that the modified MWCNTs, particularly MWCNT- quin, have considerably significant toxic impact on SKBR3 as compared to HEK293 at the concentration of 5 μg/mL.

The work presented in this report was a detailed comparative study of the electrochemical response exhibited by graphite anodes in Li-ion batteries having different physical features. A comprehensive morphological and physical characterization was carried out for these graphite samples via X-ray diffraction and scanning electron microscopy. Later, the electrochemical performance was analyzed using galvanostatic charge/discharge testing and the galvanostatic intermittent titration technique for...
