Abstract: An arc brazing method of bonding different materials includes disposing an aluminum alloy to be bonded on a steel base material and arc brazing a welded portion between the steel base material and the aluminum alloy using a wire. The wire is an alloy containing Zn. It is possible to compensate for brittleness due to the bonding of different materials and to improve wettability.

Abstract: There are provided an error correction decoder and a memory system having the same. The error correction decoder includes a node processor for performing at least one iteration of an error correction decoding based on at least one parameter used for an iterative decoding, a reliability information generator for generating reliability information corresponding to a current iteration upon a determination that the error correction decoding corresponding to the current iteration has been unsuccessful, and a parameter adjuster for adjusting the at least one parameter upon a determination that the reliability information satisfies a predetermined condition, and controlling the node processor to perform a next iteration based on the adjusted.

Abstract: Disclosed is a method for producing a renewable fuel using a supercritical fluid. The method includes charging a supported catalyst into a continuous reactor and adding a catalyst activating material thereto to activate the supported catalyst, feeding an oil or fat, hydrogen and a supercritical fluid into the continuous reactor and allowing hydrogenation and hydrodeoxygenation reactions of the oil or fat in the supercritical fluid to proceed, and collecting a renewable fuel as the reaction product. The method enables the production of an oxygen-free renewable fuel in a higher yield at a lower hydrogen pressure and a lower reaction temperature than conventional methods for producing renewable fuels.

Abstract: The present invention relates to a touch input device. The touch input device of the present invention comprises a cover unit 20 which is formed with a reflective coating layer 22 on a surface thereof and made of a transparent material; a selective transmission unit 24 which is provided on a rear surface of the cover unit 20, formed with light-emitting holes 26 indicative of their respective functions and made of an opaque material; and a touchpad module 30 which includes light emitting devices 33 provided on a rear surface of the selective transmission unit 24 to provide light to the light-transmitting holes 26 and detects whether a user's body is touched onto the surface of the cover unit 20 to receive a detection signal.

Abstract: A system for determining an interested field of an Internet user, attracting advertisements from sponsors according to the user's interest, and providing advertisements to the user via the Internet includes a keyword database for recording multiple keywords, keyword type information, predetermined reference information for the type information, and advertisement list information including the number of advertisement files including the keyword. A use event is received and a keyword is recorded as history data corresponding to the event. Keyword type information is searched using a keyword database and reference information of the type information is searched. The keyword is determined an interested field of the user according to the reference information. An advertisement file is generated including the interested field keyword.

Abstract: Provided are a method of producing a solid seasoning including: mixing at least one plant protein source selected from the group consisting of sterilized soy beans, non-fat soy beans and wheat gluten, and a liquid culture medium of kojic mold, and degrading the plant protein source under unsalted and sterile conditions; and drying the degraded product to obtain the solid seasoning, a solid seasoning produced using the method, and a general food seasoning, sauce, dressing, soy sauce or soy bean paste, or processed food including the solid seasoning.
