BACKGROUND Hearing loss can lead to a number of disabilities, subsequently reducing the quality of life. In general, hearing thresholds of adolescents are better than adults and the elderly. However, occasionally, adolescents acquire hearing loss for a number of reasons. In this study, our goal was to estimate the prevalence of hearing loss in the Korean(More)
The effects of surface passivation on the photoluminescence (PL) properties of CdS nanoparticles oxidized by straightforward H2O2 injection were examined. Compared to pristine cadmium sulfide nanocrystals (quantum efficiency ≅ 0.1%), the surface-passivated CdS nanoparticles showed significantly enhanced luminescence properties (quantum efficiency ≅ 20%).(More)
The expression and cellular localization of neuronal nitric oxide (NO) synthase (nNOS) were studied in the rabbit spinal cord following ischemic injury induced by clamping the descending aorta. In the normal spinal cord, nNOS immunoreactivity was localized to certain motor neurons located in the margin of the ventral horn. Following transient ischemia,(More)
As mobile computing gains more popularity, the challenge of providing mobile clients with ubiquitous access to data must be met. One of the main challenges is overcoming the asymmetric environment that exists between servers and mobile clients. Broadcast disks use a push-based technology to overcome such challenge in a scalable way by creation of an(More)
