종이교과서에서 디지털교과서로의 단계적 발전 방안에 관한 시론
임유나, 홍후조 한국교육학회 교육학연구 36 Pages
한국교육학회 교육학연구 2013, 51권 2호 1 1-36 (36 pages)
본 연구는 기술적으로 불완전한 수준의 디지털교과서로 현재의 종이교과서를 완전 대체하겠다는 정 부의 정책 계획에 대한 의문에서 시작되었다. 디지털교과서를 둘러싼 논의는 산업적 경제적 교육적 측면에서 일부 과장된 면이 있고, 효능이 지나치게 부풀어져 환상을 가지게 하는 경향도 있다. 디지털 교과서에 대한 선행 연구들을 분석한 결과, 많은 연구들이 학업성취도 효과성 측정에 초점을 맞추어 왔으나 디지털교과서 활용 집단이 종이교과서 활용 집단보다 학업성취도 수준이 높다는 공통된 연구 결과는 도출되지 않았다. 또한... -

인간의 정신에 대한 탐구는 오랜 역사를 그 배경으로 하고 있다. 인문학과 예술은 그동안 각 시대별로 인간의 정신적 특질을 섬세하고 개성적으로 반영해 왔다. 특히 근대 이후에는 인간정신에 대한 과학적 접근이 시작되었고 그 결과 심리학, 정신의학, 뇌 과학 등의 새로운 접근이 이루어졌으며 특히 정신병리에 대한 임상적 접근이 그 내용을 더욱 실증적으로 구체화시켰다. 정신의학은 과거 프로이드의 정신분석이론을 중요한 토대로 삼았지만 점차로 프로이드에서 벗어나 여러 갈래로 그 줄기가 나누어 졌다. 정신분석이론을... -
The electrical and heating properties of copper-incorporated graphite fibers fabricated using different ultrasonication techniques
Kyeong Min Lee, Min-Ji Kim, Hanjoo Jo, Sang Young Yeo, Young-Seak Lee 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 15 111-114 (4 pages)
Metallic materials are typically used in electrical heating elements because of their great electrical conductivity. However, metallic materials have several weaknesses, such as corrosion susceptibility, heavy weight, high manufacturing costs, and electromagnetic wave emissions [1,2]. To resolve these problems, carbon materials with good electrical conductivity, such as carbon fibers, graphite fibers, carbon nanotubes, and carbon black, have been examined as heating materials [3,4]. Among these... -
Synthesis and physicochemical characterization of NixZnx- FeO₂O₄/MWCNT nanostructures as enzyme mimetics with peroxidase-like catalytic activity
Navvabeh Salarizadeh, Minoo Sadri, Hassan Hosseini, Reza. H. Sajedi 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 14 103-110 (8 pages)
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... -
Relationships between dielectric properties and characteristics of impregnated and activated samples of potassium carbonate- and sodium hydroxide-modified palm kernel shell for microwave-assisted activation
Norulaina Alias, Muhammad Abbas Ahmad Zaini, Mohd Johari Kamaruddin 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 9 62-72 (11 pages)
The aim of this work was to evaluate the dielectric properties of impregnated and activated palm kernel shells (PKSs) samples using two activating agents, potassium carbonate (K2CO3) and sodium hydroxide (NaOH), at three impregnation ratios. The materials were characterized by moisture content, carbon content, ash content, thermal profile and functional groups. The dielectric properties were examined using an open-ended coaxial probe method at various microwave frequencies (1?6 GHz) and... -
Mechanical and electrical properties of cement paste incorporated with pitch-based carbon fiber
Inkyu Rhee, Jin Hee Kim, Sang Hee Park, Sungho Lee, Bong Ryeul Ryu, Yoong Ahm Kim 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.23 4 22-29 (8 pages)
The compressive strength and electrical resistance of pitch-based carbon fiber (CF) in cementitious materials are explored to determine the feasibility of its use as a functional material in construction. The most widely used CFs are manufactured from polyacrylonitrile (PAN-based CF). Alternatively, short CFs are obtained in an economical way using pitch as a precursor in a melt-blown process (pitch-based CF), which is cheaper and more eco-friendly method because this pitch-based CF is basically... -
EMI shielding effectiveness and mechanical properties of MWCNTs-reinforced biodegradable epoxy matrix composites
Yoon-Ji Yim, Dong Chul Chung, Soo-Jin Park 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 4 36-41 (6 pages)
employing dynamic mechanical analysis, critical stress intensity factor (KIC) tests, and impact strength tests. The electromagnetic interference shielding effectiveness (EMI-SE) of the composites was evaluated using reflection and absorption methods. Mechanical properties of MWCNTs/B-epoxy were enhanced with an increase in the MWCNT content, whereas they deteriorated when the MWCNT content was >5 parts per hundred resin (phr). This can likely be attributed to the entanglement of MWCNTs with each... -
The effects of carbon coating onto graphite filler on the structure and properties of carbon foams
Ji-Hyun Kim, Do Young Kim, Young-Seak Lee 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 16 111-115 (5 pages)
Carbon foams (CFms) are of crucial importance in electrical and mechanical devices due to their high thermal conductivity used for eliminating high heat flow and maintaining low temperatures [1]. The most common CFms are types of aluminum alloys, copper and diamond. However, the mechanical properties of metal-based heat sink materials are difficult to control at temperatures over 550°C [2,3]. Thus, CFms are actively investigated as heat sink materials because of their good properties, such as... -
A facile green reduction of graphene oxide using Annona squamosa leaf extract
Basavaiah Chandu, Venkata Sai Sriram Mosali, Bhanu Mullamuri, Hari Babu Bollikolla 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 9 74-80 (7 pages)
A highly facile and eco-friendly green synthesis of Annona squamosa (custard apple) leaf extract reduced graphene oxide (CRG) nanosheets was achieved by the reduction of graphene oxide (GO). The as-prepared CRG was characterized with X-ray diffraction (XRD), transmission electron microscope (TEM), Fourier-transform infrared spectroscopy (FT-IR), ultraviolet-visible (UV-Vis), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopic techniques. Removal of oxygen containing moieties from the... -
Mechanical properties of epoxy composites reinforced with ammonia-treated graphene oxides
Mi-Seon Park, Sangmin Lee, Young-Seak Lee 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 1 1-7 (7 pages)
The effects of ammonia-treated graphene oxide (GO) on composites based on epoxy resin were investigated. Ammonia solutions of different concentrations (14?28%) were used to modify GO. Nitrogen functional groups were introduced on the GO surfaces without significant structural changes. The ammonia-treated GO-based epoxy composites exhibited interesting changes in their mechanical properties related to the presence of nitrogen functional groups, particularly amine (C-NH2) groups on the GO...
