The timing of referral to a nephrologist may influence the outcome of chronic kidney disease patients, but its impact has not been evaluated thoroughly. The results of a recent study showing an association between early referral and patient survival are still being debated. A total of 1028 patients newly diagnosed as end-stage renal disease (ESRD) from July(More)
— In the last decade, face analysis, e.g. face recognition, face detection, face tracking and facial expression recognition, is a very lively and expanding research field. As computer animated agents and robots bring a social dimension to human computer interaction, interest in this research field is increasing rapidly. In this paper, we introduce an(More)
INTRODUCTION Severe hyperkalemia, with potassium (K+) levels ≥ 6.5 mEq/L, is a potentially life-threatening electrolyte imbalance. For prompt and effective treatment, it is important to know its risk factors, clinical manifestations, and predictors of mortality. METHODS An observational cohort study was performed at 2 medical centers. A total of 923(More)
–Socially intelligent robots are no longer an interesting topic of science fiction. In the robotics community, there is a growing interest in building personal robots, or in buidling robots that share the same workspace with humans. Natural interaction between humans and robots is therefore essential. To interact socially with humans, a robot must be able(More)
—An active vision system can control the gaze direction of mounted vision sensors and can overcome many shortcomings of other passive vision systems which have fixed vision sensors. Furthermore, most visual servoing approaches are concerned with a vision sensor or a passive stereo vision system which has fixed relative coordination between two cameras. In(More)
—In this paper, we propose a method of selecting new types of rectangle features that are suitable for facial expression recognition. The basic concept in this paper is similar to Violar's approach, which is used for face detection. Instead of previous Haar-like rectangle features we choose rectangle features for facial expression recognition among all(More)
PURPOSE The colonoscopic polypectomy has become a valuable procedure for removing precursors of colorectal cancer, but some complications can be occurred. The most common complication after colonoscopic polypectomy is bleeding, which is reported to range from 1% to 6% and which can be immediate or delayed. Because the management of delayed postpolypectomy(More)
β-1,6-glucan is a polysaccharide found in brown macroalgae and fungal cell walls. In this study, a β-1,6-endoglucanase gene from Saccharophagus degradans 2-40T, gly30B, was cloned and overexpressed in Escherichia coli. Gly30B, which belongs to the glycoside hydrolase family 30 (GH30), was found to possess β-1,6-endoglucanase activity by hydrolyzing(More)
Osmotic demyelination syndrome is a demyelinating disorder associated with rapid correction of hyponatremia. But, it rarely occurs in acute hypernatremia, and it leads to permanent neurologic symptoms and is associated with high mortality. A 44-year-old woman treated with alternative medicine was admitted with a history of drowsy mental status. Severe(More)
