Abstract: Disclosed are an artificial intelligence device and a method for operating the same. An artificial intelligence device according to at least one embodiment of various embodiments of the present disclosure includes: a display; and a processor configured to control the display, wherein the processor is configured to: receive and register a first wake-up word; activate a voice recognition function when the registered first wake-up word is received, and transmit the first wake-up word to a server, wherein the first wake-up word is not a basic wake-up word embedded in the artificial intelligence device.

Abstract: Disclosed is non-woven fabric for a vehicle internal material, a manufacturing method of the non-woven fabric, and a cargo screen for a vehicle using the non-woven fabric for a vehicle internal material, wherein the manufacturing method of non-woven fabric for a vehicle internal material is configured to includes forming a felt by mixing LM PET (Low melting polyethylene terephthalate) staple fibers having a melting point in the range of 120 to 140° C. and 150 to 170° C. and PET staple fibers; and thermo-compression molding the felt.

Abstract: An image display device and a voice recognition method thereof are proposed. The image display device and voice recognition method thereof stores received first utterance data in a first buffer when a wake up word is recognized from utterance data, stores second utterance data consecutively uttered from a user in a second buffer, stores third utterance data consecutively uttered from the user in a third buffer when verification of the wake up word is successful on the basis of the first utterance data after booting of an operating system is completed, and joins the second uttered data and the third uttered data respectively stored in the second buffer and the third buffer, so as to perform voice recognition for the utterance data consecutively uttered by the user. Accordingly, including the commands uttered at intervals after the wake up word, user's commands that are consecutively uttered may be recognized.

Abstract: The present invention relates to a recombinant expression vector which is prepared by inserting a human parathyroid hormone gene containing a urokinase-specific cleavage site into an L-arabinose inducible vector containing a phosphoribulokinase gene fragment of Rhodabacter sphaeroides or its mutated gene as a fusion partner, or its mutate gene as a fusion partner, a recombinant microorganism transformed with the said expression vector, and a process for preparing human parathyroid hormone on a large scale by cultivating the said microorganism in a medium containing L-arabinose. In accordance with the invention, a recombinant human PTH having the same activity of the native human PTH can be prepared in a high yield through the precise control of induction by a manufacturing process which comprises a step of inducing expression of fusion protein in the microorganism transformed with the recombinant expression vector by L-arabinose.
