University where she got her degrees of MS and PhD. Her current research interests are impacts of IT applications on business including mobile telecommunication industry.Abstract The objective of this study was to identify factors influencing the adoption of mobile banking service. We specifically focused our attention on perceived risk, perceived(More)
Recently, Dielectric Elastomer Actuator(DEA) comes to the market successfully by introducing commercial products such as tactile interfaces for mobile applications. As an advanced application, we present a tactile display device actuated with dielectric elastomer actuator(DEA) in this paper. By employing fluid coupling between the touch spot and the(More)
The purpose of this paper is to verify the relationships among service quality, perceived value, customer satisfaction, and customer loyalty in mobile phone service. The study conducted an empirical research. A total of 384 mobile phone users' responses were collected from Seoul in Korea. The findings show that service quality positively influences customer(More)
OBJECTIVES The Web-based integrated public healthcare information system (PHIS) of Korea was planned and developed from 2005 to 2010, and it is being used in 3,501 regional health organizations. This paper introduces and discusses development and performance of the system. METHODS We reviewed and examined documents about the development process and(More)
This paper estimates the value of Internet information by using the hedonic price model (HPM). We specify a hedonic price function, and measure the consumer's willingness to pay for attributes to the Internet connection charge. We also identify a functional form for the HPM by using the Box–Cox transformation of the variables in our analysis. Our results(More)
We have developed a modified optical frequency domain imaging (OFDI) system that performs parallel imaging of three-dimensional (3D) surface profiles by using the space division multiplexing (SDM) method with dual-area swept sourced beams. We have also demonstrated that 3D surface information for two different areas could be well obtained in a same time(More)
Advances in wireless technology have expanded the existing internet environment and accelerated the rapid development of mobile service. Many previous studies were conducted on users' needs and satisfaction prior to the expansion of the mobile service.Thus, the impact of mobile service factors on user satisfaction has important implications for both(More)
PURPOSE An epidemiological study of myasthenia gravis (MG) has not been performed in Korea. The purpose of this study was to estimate the prevalence and incidence of MG in Korea. MATERIALS AND METHODS Health Insurance Review and Assessment (HIRA) data from 2010 to 2014 were searched for MG codes as defined by the International Classification of Diseases,(More)
The objective of this study was to investigate the clinical and genetic features of Korean patients with facioscapulohumeral muscular dystrophy type 1 (FSHD), and assessed the impact of molecular defects on phenotypic expression. We enrolled 104 FSHD patients from 87 unrelated Korean families with D4Z4 repeat array of less than 11 copies on 4q35. Sixty-one(More)
A linearized wavelength-swept thermo-optic laser chip was applied to demonstrate a fiber Bragg grating (FBG) sensor interrogation system. A broad tuning range of 11.8 nm was periodically obtained from the laser chip for a sweep rate of 16 Hz. To measure the linear time response of the reflection signal from the FBG sensor, a programmed driving signal was(More)
