The use of light for medical treatment has been studied previously. In this study, we examined the effect of light from a red light-emitting diode on osteogenic differentiation of mouse mesenchymal stem cells (D1 cells) which were cultured in the presence of osteogenic differentiation medium (ODM) for 3 days, then exposed to a red light-emitting diode (LED)(More)
AIMS This study was carried out to evaluate the influence of CYP2D6 genotype on the steady state plasma concentrations of haloperidol and reduced haloperidol in Korean schizophrenic patients. METHODS One hundred and twenty Korean schizophrenic patients treated with various, clinically determined, doses of haloperidol (range 3-60, median 20 mg day-1)(More)
Public cloud storage has recently surged in popularity. However, cloud storage providers (CSPs) today offer fairly rigid services, which cannot be customized to meet individual users' needs. We propose a distributed, client-defined architecture that integrates multiple autonomous CSPs into one unified cloud and allows individual clients to specify their(More)
In this paper, we present demand-side energy management under real-time demand-response pricing as a task scheduling problem which is NP-hard. Using minmax as the objective, we show that the schedule produced by our minMax scheduling algorithm has a number of salient advantages: significant peak-shaving, cost reduction, and risk-aversion for the consumers.(More)
PythDock is a heuristic docking program that uses Python programming language with a simple scoring function and a population based search engine. The scoring function considers electrostatic and dispersion/repulsion terms. The search engine utilizes a particle swarm optimization algorithm. A grid potential map is generated using the shape information of a(More)
The aim of this study was to evaluate the outcome of 30 femoral head fractures. We modified Pipkin's classification into 4 types: I (5 cases) small fracture of head distal to fovea centralis, which was too small or too fragmented to be fixed with screws; II (18 cases), larger fracture of head distal to fovea centralis; III (4 cases), large fracture of head(More)
This paper proposes an automated classifier generation system for application-level mobile traffic identification. The proposed system comprises traffic classifier generation system architecture and mobile traffic measurement agents (mTMAs) that are installed on mobile devices to monitor their application-level traffic. To generate classifiers, our adaptive(More)
STUDY DESIGN This is a retrospective study. PURPOSE We wanted to investigate the clinical relevance of the lumbar high intensity zone (HIZ) on magnetic resonance imaging (MRI) and the relationship of trauma history to internal disc disruption (IDD). OVERVIEW OF LITERATURE HIZs on lumbar spine (L-spine) MRI have been suggested as a reliable marker of IDD(More)
