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...

In this study we explored the degree to which marriage satisfaction mediated the relationship between fathering self-efficacy and father involvement in a sample of 250 Korean fathers. It was found that fathering self-efficacy was associated with father involvement||| and marriage satisfaction. Marriage satisfaction was found to mediate the relationship between fathering self-efficacy and father involvement.

With the surging need for indoor leisure activities for Koreans due to deteriorating air condition and weather, the competitions among various business segments in the fitness industry have also grown, facing a considerable challenge for survival. Many fitness centers suffer from bad quality of service, transient and poorly trained workforce, and damaging reputation; thus, deteriorating sustainability in the long run. While a few fitness center operators offer differentiated products and...

Teacher education programs must provide opportunities for student teachers to explore their teaching aptitude early in the program and help them to strengthen their areas of weaknesses to prepare them for the realities of teaching. This study employed the cognitive diagnostic assessment framework, which is known to be effective in providing profiles of multidimensional and inter-related attributes, such as the teaching aptitude. The attribute mastery profiles of 1,111 participants from 6 South...

This study aims to examine how context-specific measures of students' interest and value differ from their context-general measures in psychometric properties across countries. Using PISA2006 Science data, differential effects of item context on assessing interest and value were illustrated in both the individual and country levels. The main findings are as follows: First, correlation between context-specific and context-general measures tended to be slightly higher in value than in interest....

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...

a laser. The X-ray diffraction data revealed that the growth of crystallite was parallel to the fiber axis, and the interlayer spacing d002 decreased from 0.353 to 0.345 nm. The results of scanning electron microscopy revealed that the surface of irradiated CFs was rougher than that of the unirradiated ones and there were scale-like small fragments that had peeled off from the fibers. The tensile modulus increased by 17.51% and the Weibull average tensile strength decreased by 30.53% after being...

With continuous development in the field of sample preparation technology, solid phase micro-extraction (SPME) has been widely used in analytical chemistry for high extraction efficiency and convenient operation. Different materials lead to different extraction results. Among existing materials, carbon-based materials are still attracting attention from scientists due to their excellent physical and chemical properties as well as their modifiable surfaces, which could enhance the adsorption...

We studied the basic properties and fabrication of reduced graphene oxide (rGO) prepared using eco-friendly reduction agents in the graphene solution process. Hydrazine is generally used to reduce graphene oxide (GO), which results in polluting emissions as well as fixed nitrogen functional groups on different defects in the graphene sheets. To replace hydrazine, we developed eco-friendly reduction agents with similar or better reducing properties, and selected of them for further analysis. In...
