인공지능, IoT, 로봇, 바이오 신기술, 3D프린팅, 자율주행 운송수단과 드론, 빅데이터 등의 초유기적인 관계가 주도하는 제4차 산업혁명은 인간의 삶에 긍정적 영향을 주지만 비인간화 및 소득의 불균형을 유발하여 중산층이 붕괴되고 민주주의를 위협하고 있다. 따라서 본고에서는 제4차 산업혁명이 추구하는 기본 목적과 가치를 위한 인간상과 핵심역량을 논의하였으며, 교육의 역할과 방향, 그리고 교육정책 수립을 위한 제언을 제시하였다. 인지능력으로 언어, 수리, 과학, 사회의 기초적인 문해와 특히 경제와 컴퓨터에 대한 문해...

본 연구에서는 경기도 내 한 혁신고등학교인 희망고등학교를 대상으로 단위학교 혁신과정을 분석하 고 그 과정에서 학생들의 역할을 고찰하였다. 연구결과는 다음과 같다. 먼저 희망고등학교의 혁신과정은 갑작스럽게 시작되었고 그로 인한 혼란을 겪었으나 현재는 새로운 가능성을 발견했다고 요약할 수 있다. 학교 구성원들의 충분한 논의를 거치지 못하고 학교 혁신의 방편으로서 혁신학교를 시작하게 되면서 교사와 학생, 지역사회 모두 혼란을 겪게 되었고, 이에 비교과교육과정을 중심으로 한 부분적인 혁신을 하였다. 그럼에도...

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...

We demonstrated the sensitivity of optically active single-walled carbon nanotubes (SWCNTs) with a diameter below 1 nm that were homogeneously dispersed in cement composites under a mechanical load. Deoxyribonucleic acid (DNA) was selected as the dispersing agent to achieve a homogeneous dispersion of SWCNTs in an aqueous solution, and the dispersion state of the SWCNTs were characterized using various optical tools. It was found that the addition of a large amount of DNA prohibited the...

Different phytochemicals obtained from various natural plant sources are used as reduction agents for preparing gold, copper, silver and platinum nanoparticles. In this work a green method of reducing graphene oxide (rGO) by an inexpensive, effective and scalable method using olive leaf aqueous extract as the reducing agent, was used to produce rGO. Both GO and rGO were prepared and investigated by ultraviolet and visible spectroscopy, Fourier-transform infrared, scanning electron microscopy,...

Polyacrylonitrile/pitch nanofibers were prepared by electrospinning as a precursor for a gas sensor material. Pitch nanofibers were properly fabricated by incorporating polyacrylonitrile as an electrospinning supplement component. Polyacrylonitrile/pitch nanofibers were activated with steam at various temperatures followed by subsequent carbonization to make carbon nanofibers with a highly conductive graphitic structure. Steam activation was effective in facilitating gas adsorption onto the...

In gas adsorption processes, activated carbon fibers (ACFs) are used for the adsorption of the harmful gases that are generated by coal or oil combustion, and they have been widely studied [1,2]. ACFs have been used for harmful gas removal because of their specific surface area, micropores, reproducibility, safety, and processing ability, which are beneficial properties for a wide range of applications [3,4].

This research considers the effect of added mesophase pitch (MP) as an additive during the pitch synthesis reaction of pyrolyzed fuel oil (PFO). Two effects are generated by adding MP. One is an enhancement of thermal stability due to the high thermal property of the additive; the other is that the volatile compounds that were removed by vaporization of PFO during the thermal reaction can participate in the pitch synthesis reaction (PFO→pitch) more efficiently. The effect differs according to...
