Abstract: An example electronic device includes a display, a communication circuit, a memory, and at least one processor configured to, based on a signal for requesting transmission of identification information including a call word for using first mode of an artificial intelligence assistant function of the electronic device being received, from another electronic device, through the communication circuit using first communication method, control the display to display a user interface for requesting user confirmation for transmission of the identification information; control the communication circuit to transmit the identification information to the another electronic device as a result of user confirmation through the user interface; and receive information for using a second communication method from the another electronic device.

Abstract: Disclosed herein are a catalyst for hydrocracking reaction of high molecular weight components in bio-oil, a method for preparing the same and a method for bio-oil upgrading using the same. The catalyst includes a zeolite carrier; and at least one metal selected from the group consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) supported on the carrier. The catalyst promotes the hydrocracking of high molecular weight compounds contained in the bio-oil, but also inhibits the polymerization reaction of the decomposed product, thereby more effectively enhancing the hydrocracking reaction of the bio-oil.

Abstract: Proposed is a method of manufacturing a carbon precursor fiber for a gas diffusion layer having excellent tensile properties (e.g., strength and modulus) by controlling the cross-sectional shape of carbon fiber. The method includes preparing a polyacrylonitrile-based copolymer, preparing spinning products by spinning a spinning solution containing the polyacrylonitrile-based copolymer in a coagulation bath, and obtaining a carbon precursor fiber by drawing the spinning products through heat treatment. The coagulation bath includes an amount of about 60% to 90% by volume of methanol and an amount of about 10% to 40% by volume of dimethylformamide based on the total volume of the coagulation bath.

Abstract: A water drain structure of a sunroof includes a pair of guide rails disposed in a longitudinal direction of a vehicle body at both ends of a roof panel. A front drip is coupled to front ends of the pair of guide rails, the front drip having a water drain channel. An inner rail is disposed in each of the guide rails. The inner rails form a path of the sunroof at both sides from a projection formed at a center region of the guide rails in the longitudinal direction and an outer rail for keeping rainwater. A storage unit is disposed at a portion of a rear end of the outer rail and is divided into a plurality of rainwater storage spaces to keep rainwater flowing therein.
