The main objective of this study was to determine the effect of stimulus rate and gender on auditory brainstem response (ABR) latency and amplitude in Korean young adults. A total of thirty young adults consisting of fifteen males and fifteen females participated in the study. We performed this study by analyzing the latencies and amplitudes of ABR wave I, Ⅲ, and V as a function of low stimulus rate and gender. The stimulus repetition rate was changed in five steps: 8, 16, 21, 32, and 64/s....

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...

여가과몰입은 스트레스를 동반하는 수준으로 과도하게 여가활동에 몰두하는 것을 말한다. 본 연구의 목적은 여가과몰입과 삶의 만족도 간 관계에서의 가족만족도의 중재효과를 검증하는 것이다. 본 연구에서는 전국 규모의 여가 관련 실태조사를 위해 표집된 1805명의 성인(남자 893명, 여자 912명)에게 인구학적인 변인들에 대한 질문지와 더불어 여가과몰입, 삶의 만족도 및 가족 만족도 척도에 응답하도록 요청하였다. 본 연구 결과, 여가과몰입은 삶의 만족도와는 정적인 상관을 그리고 가족만족도와는 부적인 상관을 나타냈다. 또...

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...

In this study, composite PAN-based ACNFs embedded with MgO and MnO2 were prepared by the electrospinning method. The resultant pristine ACNFs, ACNF/MgO and ACNF/MnO2 were characterized in terms of their morphological changes, SSA, crystallinity and functional group with FESEM-EDX, the BET method, XRD and FTIR analysis, respectively. Results from this study showed that the SSA of the ACNF/MgO composite (1893 m2 g?1) is significantly higher than that of the pristine ACNFs and ACNF/MnO2 which is...

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...

Multiwall carbon nanotubes (MWCNT) with two different (L/D) aspect ratios (7±2 μm/140±30 nm and 0.5?2 μm/8?15 nm) were surface treated using nitric acid (HNO3) and polyethyleneimine (PEI) prior to their deposition on carbon fibers (CF). Before the hierarchical reinforcement with CF-MWCNT, the CFs were treated with 3-glycidoxypropyltrimethoxysilane, a coupling agent (Z6040) and with poly(amidoamine) (PAMAM) a dendrimer containing an ethylenediamine core and amine surface groups. The MWCNT...
