IEEE 802.11e MAC (medium access control) is one of the IEEE 802.11 WLAN (wireless local area network) standards define for QoS (quality of service) support on the wireless communications. The 802.11e MAC is based on both center controlled channel access and contention-based channel access mechanisms. EDCA (enhanced distributed coordination function) is(More)
Human rhinoviruses (HRVs), in the Enterovirus genus within the family Picornaviridae, are a highly prevalent cause of acute respiratory infection (ARI). Enteroviruses are genetically highly variable, and recombination between serotypes is known to be a major contribution to their diversity. Recently it was reported that recombination events in HRVs cause(More)
An outbreak of nosocomial infections with Middle East respiratory syndrome coronavirus occurred in South Korea in May 2015. Spike glycoprotein genes of virus strains from South Korea were closely related to those of strains from Riyadh, Saudi Arabia. However, virus strains from South Korea showed strain-specific variations.
AIMS To estimate the effect of levetiracetam (LEV) on cognitive function and mood status in newly diagnosed epilepsy patients. METHODS Fifty-five drug-naïve epilepsy patients (M:F ratio = 31:24; mean age = 30.9 years) were included. All patients underwent two neuropsychological (NP) tests, one before receiving LEV and then another 12.9 ± 5.0 months after(More)
In May 2015, Middle East respiratory syndrome coronavirus infection was laboratory confirmed in South Korea. Patients were a man who had visited the Middle East, his wife, and a man who shared a hospital room with the index patient. Rapid laboratory confirmation will facilitate subsequent prevention and control for imported cases.
BACKGROUND The aim of this study is to verify the feasibility of using silk fibroin (SF) as a potential membrane for guided bone regeneration (GBR). METHODS Various cellular responses (i.e., cell attachment, viability, and proliferation) of osteoblast-like MG63 cells cultured on an SF membrane were quantified. After culturing on an SF membrane for 1, 5,(More)
Middle East respiratory syndrome coronavirus (MERS-CoV) causes severe cases of human respiratory disease. Since 2012, the victims have mainly come from the Middle East countries or sporadically from some other geographical regions seeded by the travelers who visited the Middle East. Such an introduction through travelling led to the emergence of a MERS-CoV(More)
This study aimed to isolate a lignan-enriched fraction from Schisandra chinensis and improve the dissolution of biologically active lignans via solid dispersion (SD) formulation. Lignan-enriched fraction was obtained from a hexane-soluble extraction, being poorly soluble in water. To improve the dissolution of major lignans from these extracts, SD(More)
There is a paucity of complete genome sequence information for human respiratory syncytial virus (HRSV). To this end, we sequenced the complete genome sequences of HRSV genotype A (HRSV-A/IC688/12) and genotype B (HRSV-B/GW0047/14 and HRSV-B/IC0027/14). This information will increase the understanding of HRSV genetic diversity, evolution, pathogenicity,(More)
