최근 과학과 의료의 발달 및 수명 연장에 따른 노인인구의 증가로 인해 신부전에 이환될 가능성이 높아졌으며, 말기 신부전증의 주요 원인인 당뇨병과 고혈압 환자가 증가하고 있어, 신 대체 요법을 필요로 하는 말기 신부전증 환자가 급격히 증가하고 있다(Kim, 2008). 대한 신장 학회 등록위원회(2010)의 조사에 의하면 국내의 신 대체요법을 받고 있는 말기 신부전증 환자 수는 해마다 증가하여 처음 조사된 1986년에 2,534명이던 환자수가 2009년에는 56,396명으로 22배 이상으로 되었으며 계속 증가할 전망이다. 이중에서 혈액투석을... -
다채널보청기의 압축 방식에 따른 문장인지도와 선호도의 비교

현재 보청기의 기술은 디지털 기술의 접목으로 난청인의 의 사소통 능력의 개선에 많은 도움을 주고 있다. 최근까지의 보청 기의 기술을 간략히 살펴보면 채널 수의 증가, 음향피드백, 폐 쇄효과, 잡음 등의 효과적인 제어, 난청인이 듣기 힘든 고주파 수 대역의 정보를 잔존청력이 남아 있는 주파수 대역에서 듣게 하는 주파수하강(frequency lowering), 양측에 착용한 보청기 의 정보를 서로 교환하여 신호를 처리하는 양이통신 등이 있다 (Bohnert et al., 2010; Glista et al., 2009; Lee, 2014). 그러나 보 청기의 기술이... -
어음잡음하에서 자모음비에 따른 감각신경성난청인의 무의미음절인지도
공혜경, 주연미, 이경원 한국청각언어재활학회 Audiology and Speech Research 7 Pages
한국청각언어재활학회 Audiology and Speech Research 2013, 제 9권 제 1호 5 33-39 (7 pages)
감각신경성난청(sensorineural hearing loss, SNHL)인 은 와우 내 유모세포의 손상으로 청력역치(hearing threshold level, HTL)가 상승하며 이로 인해 역동범위(dynamic range)가 감소하여 다양한 소리의 청취에 어려움을 겪는 다. 또한 중추청각처리시스템의 기능 저하로 인하여 시간 (temporal) 및 주파수(spectral) 해상도가 저하되어 단어 인지도(word recognition score, WRS)가 감소하며 특히 잡음으로부터 목표어음을 분리하고 인지하는데 어려움이 있다(Dreschler & Plomp, 1985; Shobha et al., 2008; Tyler et al., 1982; Van... -

Optical sensitivity of DNA-dispersed single-walled carbon nanotubes within cement composites under mechanical load
Jin Hee Kim, Inkyu Rhee, Yong Chae Jung, Sumin Ha, Yoong Ahm Kim 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 12 90-96 (7 pages)
of DNA with respect to the cement was found to be 0.05 wt%. The strong Raman signals coming from the SWCNTs entrapped in the cement composites enabled us to understand their dispersion state within the cement as well as their interfacial interaction. The G and G’ bands of the SWCNTs sensitively varied under mechanical compression. Our results indicate that an extremely small amount of SWCNTs can be used as an optical strain sensor if they are homogeneously dispersed within cement composites. -
Comparative numerical evaluation for the low velocity impact behavior of T300 and T800 composite system
Jae-Seok Choi, Heung Soap Choi, Soo-Jin Park, Myung Kyun Park 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 9 89-95 (7 pages)
Carbon fiber reinforced polymer (CFRP) composites have been used for many decades for extreme light weight design purposes in various areas, such as the aerospace industry, automobiles, sports goods and etc. because they provide the advantages of high specific strength and high rigidity [1]. In particular, the fuselage and wings of various aircraft, as well as the load bearing structures and components of mechanical and civil engineering systems are currently being manufactured with CFRP.... -
Three-dimensional porous graphene materials for environmental applications
Muruganantham Rethinasabapathy, Sung-Min Kang, Sung-Chan Jang, Yun Suk Huh 한국탄소학회 Carbon Letters 13 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 1 1-13 (13 pages)
Porous materials play a vital role in science and technology. The ability to control their pore structures at the atomic, molecular, and nanometer scales enable interactions with atoms, ions and molecules to occur throughout the bulk of the material, for practical applications. Three-dimensional (3D) porous carbon-based materials (e.g., graphene aerogels/hydrogels, sponges and foams) made of graphene or graphene oxide-based networks have attracted considerable attention because they offer low... -
Effects of maleic anhydride content on mechanical properties of carbon fibers-reinforced maleic anhydride-grafted-polypropylene matrix composites

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 spectroscopy, and single fiber contact angle method. The mechanical properties of the composites were also measured by a critical stress intensity factor (KIC). From the KIC test results, the KIC values were increased to a maximum value of 3.4 MPa with the 0.1 % of MA in the PP, and then decreased with higher MA content. -

In efforts to characterize and understand the properties and processing of phenylethynyl-terminated imide (LaRC PETI-5, simply referred to as PETI-5) oligomers and polymers as a high-temperature sizing material for carbon fiber-reinforced polymer matrix composites, PETI-5 imidization and thermal curing behaviors have been extensively investigated based on the phenylethynyl end-group reaction. These studies are reviewed here. In addition, the use of PETI-5 to enhance interfacial adhesion between... -

Lignocellulosic biomass conversion to biofuels such as ethanol and other value-added bio-products including activated carbons has attracted much attention. The development of an efficient, cost-effective, and eco-friendly pretreatment process is a major challenge in lignocellulosic biomass to biofuel conversion. Although several modern pretreatment technologies have been introduced, few promising technologies have been reported. Microwave irradiation or microwave-assisted methods (physical and...
