摘要： Disclosed are a context-based arithmetic encoding apparatus and method and a context-based arithmetic decoding apparatus and method. The context-based arithmetic decoding apparatus may determine a context of a current N-tuple to be decoded, determine a Most Significant Bit (MSB) context corresponding to an MSB symbol of the current N-tuple, and determine a probability model using the context of the N-tuple and the MSB context. Subsequently, the context-based arithmetic decoding apparatus may perform a decoding on an MSB based on the determined probability model, and perform a decoding on a Least Significant Bit (LSB) based on a bit depth of the LSB derived from a process of decoding on an escape code.

摘要： Disclosed herein are Xylitol dehydrogenase-inactivated and arabinose reductase-inhibited mutant of Candida tropicalis, a method of producing a high yield of xylitol using the same, and xylitol produced by the method. More specifically, disclosed are a method for producing a high yield of xylitol, in which a high concentration of xylose contained in a biomass hydrolyzate is converted to xylitol using xylitol dehydrogenase-inactivated mutant of Candida tropicalis, without controlling dissolved oxygen to a low level, as well as xylitol produced according to the method. Also disclosed are a xylitol production method, in which the production of byproduct arabitol, which is produced when using a biomass as a substrate and adversely affects the yield of xylitol, is significantly reduced through the use of Candida tropicalis mutant ara-89 (KCTC 11136bp) having an inhibited activity of arabinose reductase converting arabinose to arabitol, thus increasing xylitol productivity, as well as xylitol produced by the method.
