BACKGROUND Bioimpedance analysis (BIA) helps measuring the constituents of the body noninvasively. Prior studies suggest that BIA-guided fluid assessment helps to predict survival in dialysis patients. We aimed to evaluate the clinical usefulness of BIA for predicting the survival rate of hemodialysis patients in Korea. METHODS We conducted a(More)
We introduce a multiple-pass sketch-based user interface, designed for novice users, which avoids spatial ambiguities and hence allows considerable freedom in creating 3D animations. The user first draws the path along which a character or object is to move. A vertical motion window is then erected along this path, on which the user specifies the(More)
We present a sketch-based user interface, which was designed to help novices to create 3D character animations by multi-pass sketching, avoiding the ambiguities usually present in sketch input. Our system also contains sketch-based editing and reproducing tools, which allow paths and motions to be partially updated rather than wholly redrawn; and graphical(More)
