ObjectiveaaHuntington's disease (HD) is a rare neurological disorder, and its current status in Korea not well investigated.This study aims to determine the prevalence incidence of HD investigate clinical features patients Korea.MethodsaaWe estimated crude annual based on databases Rare Diseases Registry (RDR) National Health Insurance (NHI).The data genetically confirmed was collected from 10 referral hospitals analyzed.ResultsaaThe mean calculated 0.06 cases per 100,000 persons, 0.38 NHI...
This study was conducted to verify how the illuminance and correlated color temperature of LED lighting affect working memory. For this study, an automatic device based on a light sensor developed used, conditions were treated with total six (2 × 3): two (dim: 400 lx, bright: 1,000 lx) three (3,000 K, 5,000 7,000 K). There 30 participants in average age 21.6 years (Standard deviation = 1.92). Participants assigned all conditions, placement order randomized. measurement memory, 3-back task...
The purpose of this study was to improve the speech processing strategy for cochlear implants (CIs) based on a nonlinear time-varying filter model biological cochlea. level-dependent frequency response characteristic basilar membrane is known produce robust formant representation and perception in noise. A dual resonance (DRNL) adopted because it simpler than other adaptive models can be readily incorporated into CI processor. Spectral analysis showed that information more saliently...
The fact that the illuminance of LED lights affects human attention and long-term memory has been verified through various studies, but there are no consistent research results about what level is effective. aims this study were to systematically verify effects lighting on memory. experiment was designed with four levels—300 lx, 400 500 1,000 lx—as experimental conditions determine Participants in 18 college students. task performed using a handmade measuring instrument. Long-term measured...
Although many studies show that thromboxane A2 (TXA2) has the action of gastrointestinal (GI) motility using GI muscle cells and tissue, there are no reports on effects TXA2 interstitial Cajal (ICC) function as pacemaker in tract. So, we studied modulation activities by ICC with whole cell patch-clamp technique. Externally applied (5μM) produced membrane depolarization current-clamp mode increased tonic inward currents voltage-clamp mode. The were inhibited intracellular application GDP-β-S....
The purpose of this study was to verify the forms effect serial position effects memory according illuminance light. This conducted as an experimental method, and 21 adults without cognitive impairment participated in study. condition designed with high 1,000 lx low 300 lx. task used word list 20 items consisting a series pointless spellings. After memorizing for 10 minutes, participant performed retention 24 hours later. consisted filling empty part learned completing word. analysis by...
Background Transient global amnesia (TGA) might be related to an ischemic event with characteristic findings in diffusion-weighted images (DWIs). However, acute lesions are uncommon. The aim of this study was identify any clinical or radiological differences between TGA patients and without lesions. Methods From January 2010 through March 2015, we identified retrospectively DWIs within 7 days from onset. According the presence lesion hippocampus, features, vascular risk factors,...
The purpose of this study was to improve speech perception performance cochlear implant (CI) under noise by a processing strategy based on nonlinear time-varying filter model biological cochlea, which is beneficial in preserving spectral cues for perception. A dual resonance applied implement feature. Time-frequency analysis indicated that formant information more clearly represented at the output CI processor, especially noise. Acoustic simulation and hearing experiment also showed...
