Hearing impairment is one of the most common physical disabilities in the world. Conductive hearing loss results from dysfunction of the middle ear, and sensorineural hearing loss results from abnormalities within the cochlea or central nervous system. To improve the diagnosis of hearing loss and develop new technologies for restoration of hearing, changes of the middle ear and cochlear functions in relation to ear structural disorders in hearing impaired ears need to be characterized. This...

현대미술에서의 알레고리에 대한 개념은 포스트모더니즘 미술의 다양한 양상에 대한 본질적 인 표현충동과 연관되어 정의되고 있다. 특히 폴 드 만은 알레고리를 언어의 해체적 특성과 관련하여 접근함으로써 모더니즘 이후의 다원적인 포스트모니즘의 양상을 현대 알레고리의 해체적 특성으로 규정하고 알레고리 담론을 태동시키고 있다. 이를 배경으로 크랙 오웬스는 알레고리를 본질적으로 복합적이고 다양한 양상(polyvalent)을 지닌 포스트모더니즘의 예술적 특징들과 관련짓고, 알레고리를 ‘예술적 기법이자 예술적 태도이며...

explores how asymmetric item response models can be extended to accommodate various psychometric applications through linking such as differential item functioning or computerized adaptive testing. From the simulation study, a linking method using concurrent calibration in common-item and non-equivalent group design worked reasonably well in defining a consistent metric compared to non-linking separate calibration, as demonstrated by ICC recovery and adequate separation of group proficiencies in...

이 연구의 목적은 현실과 가상, 존재하는 것과 존재하지 않는 것의 구분이 모호해지면서 실재감을 상 실한 포스트모더니즘의 세계 속에서, 교육에서 요청되는 세계개념은 어떠한 것일 수 있는지를 Hannah Arendt의 세계개념을 통하여 탐색하는 데에 있다. 이를 위하여 이 논문의 II장에서는 서구사상사에서 그 동안 세계의 의미가 어떻게 변천되어 왔는지를 개관한다. III장에서는 Arend의 세계 개념에 대하여 탐색 한 후, IV장에서는 Arend의 세계 개념이 우리 교육의 방향에 대하여 시사하는 바가 무엇인지를 살펴본 다. 연구결과,...

In this study, Fe-Ni bimetallic catalyst supported on kaolin is prepared by a wet impregnation method. The effects of mass of kaolin support, pre-calcination time, pre-calcination temperature and stirring speed on catalyst yields are examined. Then, the optimal supported Fe-Ni catalyst is utilised to produce multi-walled carbon nanotubes (MWCNTs) using catalytic chemical vapour deposition (CCVD) method. The catalysts and MWCNTs prepared using the optimal conditions are characterized using high...

Multi-walled carbon nanotube (MWCNT)/polycarbonate (PC) nanocomposite was prepared by direct melt mixing to investigate the effect of the shear rate on the surface resistivity of the nanocomposites. In this study, an experiment was carried out to observe the shear induced orientation of the MWCNT in the polymer matrix using a very simple melt flow indexer with various loads. The compression-molded, should be eliminated. MWCNT/PC nanocomposite sample exhibited lower percolation thresholds (at 0.8...

Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as...

Multi-walled carbon nanotube (MWCNT)/epoxy composites are prepared by a vacuum assisted resin transfer molding (VARTM) method. The mechanical properties, fracture surface morphologies, and thermal stabilities of these nanocomposites are evaluated for epoxy resins with various amounts of MWCNTs. Composites consisting of different amounts of MWCNTs displayed an increase of the work of adhesion between the MWCNTs and the matrix, which improved both the tensile and impact strengths of the...
