영상자극 유형에 따른 유아의 정서안정성과 스트레스에 관한 연구 : 뇌파 측정을 중심으로
최혜순, 남효순 한국어린이미디어학회 어린이미디어연구 20 Pages
한국어린이미디어학회 어린이미디어연구 2012, 제 11권 제 2호 4 69-88 (20 pages)
본 연구는 영상자극의 유형에 따라서 유아의 정서안정성과 스트레스에 어떠한 차이가 있는지 살펴보 기 위해 뇌 과학적 연구방법의 하나로 대두되고 있는 뇌파(Electroencephalogram, EEG)측정을 실행 하였다. 연구 대상은 만 5세 유아 33명이며, 뇌파 측정 장비(QEEG-4 System)로 유아별 기초뇌파를 측정한 후 컴퓨터 모니터를 통해 정적영상자극과 동적영상자극을 차례로 제시하고 이를 통해 유발된 정서안정성과 스트레스에 관한 뇌파지수를 측정 하였다. 분석 결과는 다음과 같다. 첫째, 정서안정성 에 관한 뇌파지수는 기초자극,... -
Nitrogen-doped carbon nanosheets from polyurethane foams and removal of Cr(VI)
Jiaqi Duan, Baohua Zhang, Huailin Fan, Wenzhong Shen, Shijie Qu 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 7 60-69 (10 pages)
Nitrogen-doped carbon nanosheets with a developed porous structure were prepared from polyurethane foams by hydrothermal carbonization following ZnCl2 chemical activation. Scanning electron microscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, solid state 13C nuclear magnetic resonance (NMR) spectra and X-ray photoelectron spectroscopy were used to characterize the nitrogen-doped carbon nanosheet structure and composition. The removal of Cr(VI) by the N-doped carbon... -
Study of complex electrodeposited thin film with multi-layer graphene-coated metal nanoparticles
Young-Lae Cho, Jung-woo Lee, Chan Park, Young-il Song, Su-Jeong Suh 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 8 68-73 (6 pages)
We have demonstrated the production of thin films containing multilayer graphene-coated copper nanoparticles (MGCNs) by a commercial electrodeposition method. The MGCNs were produced by electrical wire explosion, an easily applied technique for creating hybrid metal nanoparticles. The nanoparticles had average diameters of 10?120 nm and quasispherical morphologies. We made a complex-electrodeposited copper thin film (CETF) with a thickness of 4.8 μm by adding 300 ppm MGCNs to the electrolyte... -
Effects of maleic anhydride content on mechanical properties of carbon fibers-reinforced maleic anhydride-grafted-polypropylene matrix composites
Hyun-Il Kim, Woong Han, Woong-Ki Choi, Soo-Jin Park, Kay-Hyeok An, Byung-Joo Kim 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 6 39-46 (8 pages)
In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared... -
Adsorption of lisinopril and chlorpheniramine from aqueous solution on dehydrated and activated carbons
El-Said I. El-Shafey, Haider A. J. Al-Lawati, Wafa S. H. Al-Saidi 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 2 12-22 (11 pages)
Date palm leaflets were used as a precursor to prepare dehydrated carbon (DC) via phosphoric acid treatment at 150°C. DC, acidified with H3PO4, was converted to activated carbon (AC) at 500°C under a nitrogen atmosphere. DC shows very low surface area (6.1 m2/g) while AC possesses very high surface area (829 m2/g). The removal of lisinopril (LIS) and chlorpheniramine (CP) from an aqueous solution was tested at different pH, contact time, concentration, and temperature on both carbons. The... -
Cellulose-based carbon fibers prepared using electron-beam stabilization
Min Il Kim, Mi-Seon Park, Young-Seak Lee 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.18 9 56-61 (6 pages)
Cellulose fibers were stabilized by treatment with an electron-beam (E-beam). The properties of the stabilized fibers were analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. The E-beam-stabilized cellulose fibers were carbonized in N₂ gas at 800°C for 1 h, and their carbonization yields were measured. The structure of the cellulose fibers was determined to have changed to hemicellulose and... -
Functionalization of graphene nanoplatelets using sugar azide for graphene/epoxy nanocomposites
Saswata Bose, Lawrence T. Drzal 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 5 101-106 (6 pages)
We report a covalent functionalization of graphene nanoparticles (GnPs) employing 2,3,4-Tri-O-acetyl-β-D-xylopyranosyl azide followed by fabrication of an epoxy/functionalized graphene nanocomposite and an evaluation of its thermo-mechanical performance. Successful functionalization of GnP was confirmed via thermal and spectroscopic study. Raman spectroscopy indicated that the functionalization was on the edge of the graphene sheets; the basal plane was not perturbed as a result of the... -
Preparation and characterization of carbon fiber-reinforced thermosetting composites: a review
Fan-Long Jin, Soo-Jin Park 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 1 67-77 (11 pages)
Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs.... -
Breakthrough behaviour of activated charcoal cloth samples against oxygen analogue of sulphur mustard
G. K. Prasad, J. Praveen Kumar, P. V. R. K. Ramacharyulu and Beer Singh 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 3 19-24 (6 pages)
The breakthrough behaviour of activated charcoal cloth samples against an oxygen analogue (OA) of sulphur mustard has been studied using the modified Wheeler equation. Activated charcoal cloth samples having different surface area values in the range of 481 to 1290 m2/g were used for this purpose. Breakthrough behaviour was found to depend on the properties of the activated charcoal cloth, properties of the OA and the adsorption conditions. Activated charcoal cloth with a high surface area of...
