The chemical composition of aerosols measured at Cheju Island, Korea, over the 3-year period March 1992 to February 1995 are presented and discussed, with a particular emphasis on the Pacific Exploratory Mission in the Western Pacific (PEM-West B) time period. Cheju Island is under the influence of continental outflow conditions nearly 70% of the year, and(More)
This paper presents new material data for single-and multi-layer CMOS compatible poly-SiGe films, including mechanical quality factor (Q), Young's modulus, and strain gradient. Using audio frequency folded-flexure comb-drive resonators, the mechanical quality factor of poly-SiGe was determined at 2µTorr pressure. As-deposited poly-SiGe has Q = 20,000 –(More)
Toluene gas was successfully measured at room temperature using a device microfabricated by a nanoimprinting method. A highly uniform nanoporous thin film was produced with a dense array of titania (TiO(2)) pores with a diameter of 70 ≈ 80 nm using this method. This thin film had a Pd/TiO(2) nanoporous/SiO(2)/Si MIS layered structure with Pd-TiO(2) as the(More)
A DNA hybridization sensor using pentacene thin film transistors (TFTs) is an excellent candidate for disposable sensor applications due to their low-cost fabrication process and fast detection. We fabricated pentacene TFTs on glass substrate for the sensing of DNA hybridization. The ss-DNA (polyA/polyT) or ds-DNA (polyA/polyT hybrid) were immobilized(More)
OBJECTIVES This study describes the outbreaks of H5N8 highly pathogenic avian influenza (HPAI) in Korea during the first wave, from January 16, 2014 through July 25, 2014. Its purpose is to provide a better understanding of the epidemiology of H5N8 HPAI. METHODS Information on the outbreak farms and HPAI positive wild birds was provided by the Animal and(More)
The number of pesticides used in agriculture is increasing steadily, leading to contamination of soil and drinking water. Herein, we present a microfluidic platform to detect the extent of contamination in soil samples. A microchip capillary electrophoresis system with in-channel electrodes was fabricated for label-free electroanalytical detection of(More)
STUDY DESIGN Descriptions of technical strategies to overcome pitfalls associated with early learning periods in biportal endoscopic spinal surgery (BESS). PURPOSE To introduce BESS for lumbar spinal diseases (LSDs) and to inform certain challenges to be overcome in mastering the technique. OVERVIEW OF LITERATURE BESS has shown superior benefits(More)
OBJECT Most thoracolumbar fractures have a good healing outcome with adequate treatment. However, posttraumatic thoracolumbar kyphosis can occur in a proportion of thoracolumbar fractures after inappropriate treatment, osteoporosis, or osteonecrosis of the vertebral body. There are several surgical options to correct posttraumatic thoracolumbar kyphosis,(More)
The college of Information and Communication Engineering covers electrical, electronic and computer engineering which play a pivotal role in today's global industry. The broad, interrelated research fields of the college of Information and Communication Engineering include electrical energy systems, control measuring and automation telecommunication and(More)
An integrated continuous-flow microfluidic chip was fabricated on glass substrate with PDMS based microchannels, cell lysis and PCR modules. Gold-microelectrodes were used to produce electrochemical cell lysis, while, indium-tin-oxide (ITO) microheater was used for thermal cycling of PCR reaction. The fabricated device was used for 20 cycles of PCR(More)
