이음향방사(Otoacoustic Emission, OAEs)는 신경부위의 정상여부와 상관없이 발생되는 것으로 청신경의 전단계인 와우관의 능동적 활동에 물리적 기전을 제공하는 외유모세포의 반응을 측정하는 것이다. 따라서 외유모세포의 손상을 일찍 감지할 수 있는 민감성으로 이독성 약물이나 소음, 혹은 연령에 따른 와우의 변화 상태를 신속하게 추적관찰할 수 있다.14) 그 중 1979년 Kemp에 의해 측정된 변조이음향방사(DPOAE)는 검사의 비침습성과 짧은 검사시간 안정된 결과 및 재현성으로 임상적 유용성이 점차 확대되고 있다. 특히,...

We report on the dispersion state of partially reduced graphene oxide (PRGO) in organic solvents, namely methyl ethyl ketone, ethyl acetate, methylene chloride, toluene, and xylene, by controlling the carbon to oxygen (C/O) atomic ratio of the PRGOs. A two-phase solvent exchange method is also proposed to transfer PRGO from water to an aprotic solvent, such as methyl ethyl ketone. We achieve relatively good dispersion in aprotic and non-polar solvents by controlling the C/O atomic ratio of the...

This study synthesized pure anatase carbon doped TiO₂ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy...

Carbon blacks (CBs) have been widely used as reinforcing materials in advanced rubber composites. The mechanical properties of CB-reinforced rubber composites are mostly controlled by the extent of interfacial adhesion between the CBs and the rubber. Surface treatments are generally performed on CBs to introduce chemical functional groups on its surface. In this study, we review the effects of various surface treatment methods for CBs. In addition, the preparation and properties of CB-reinforced...

Global warming is considered one of the great challenges of the twenty-first century. In order to reduce the ever-increasing amount of methane (CH4) released into the atmosphere, and thus its impact on global climate change, CH4 storage technologies are attracting significant research interest. CH4 storage processes are attracting technological interest, and methane is being applied as an alternative fuel for vehicles. CH4 storage involves many technologies, among which, adsorption processes...

리튬이차전지는 21세기 정보화 및 환경친화적 사회를 뒷받침하는 핵심적인 에너지저장 및 동력원으로 사용되고 있어 소형이면서도 고출력, 장수명,대용향 전지 개발을 목표로 연구가 진행되고 있다. 현재 리튬이차전지는 기존의 휴대용 전화기,notebook의 구동전원 이외에도 새로운 CDMA, PDAd의 전원으로 채용되기 때문에 소형이면서도 무게가 가벼운 리튬이차전지의 수요는 앞으로도 꾸준하게 10%이상의 시장이 확대되어질 것으로 예상되고 있다.
