Abstract: Provided is a method of manufacturing a zinc-plated steel sheet. The method includes: coating a metal on the steel sheet on a steel sheet; annealing the metal coated steel sheet; and zinc plating the annealed steel sheet by dipping in a molten zinc plating bath. Further provided is a method of manufacturing a hot-press part including: coating a metal on the steel sheet on a steel sheet; annealing the metal coated steel sheet; zinc plating the annealed steel sheet by dipping in a molten zinc plating bath; heating the zinc-plated steel sheet; and press forming the heated steel sheet.

Abstract: The present invention relates to a novel compound exhibiting anti-inflammatory activity, and the compound of the present invention plays a key role in the generation of pro-inflammatory cytokines, thereby having excellent inhibitory activity against p38 MAPK, which is known to cause inflammatory diseases, and thus can be effectively used as an agent for treating inflammatory diseases.

Abstract: A pedal device for vehicles includes: a pedal arm provided in a pedal housing and connected to a pedal pad at a first end thereof, and rotated around a hinge shaft mounted to a second end of the pedal arm; a pressure member, a first end of which is held by the first end of the pedal arm, and a second end of which is placed between the hinge shaft and an inner surface of the pedal housing; and an elastic member provided between a middle portion of the pressure member and the inner surface of the pedal housing, and functioning to impose an elastic reaction force on the pressure member when a driver presses the pedal pad down. The elastic member brings the second end of the pressure member into frictional contact with the inner surface of the pedal housing.

Abstract: A method of generating an authentication code in a digital device is provided. An ID set in a digital device is read when it is requested to generate an authentication code. It is determined whether the authentication code previously generated based on the ID is stored in the digital device. A new authentication code is generated based on the ID and stored when the authentication code is not stored. A part of the authentication code is displayed. Only the serial number can be displayed in the authentication code. The ID is a unique and fixed value set when the digital device is produced. And, the ID is extracted from an authentication code stored in the digital device and the extracted ID is compared with the read ID so that it is determined whether the authentication code is previously generated or is not generated yet.

Abstract: A torsion beam type suspension and a forming method of a torsion beam are disclosed. In the torsion beam type suspension comprising a pair of left and right trailing arms connected to each other through a torsion beam, front ends of the trailing arms being used to mount a vehicle body by using joints, the torsion beam is obtained by forming an overall length of a pipe having a certain wall thickness by using a pressure forming process. In this case, end sections defined at both end portions of the torsion beam have a cross-sectional shape of a hollow oval, a center section defined at a center portion of the torsion beam has a cross-sectional shape of a hollow open loop, and middle sections defined between the center portion and both the end portions of the torsion beam have a cross-sectional shape of a hollow open loop. The loop of the middle sections defines an inner space larger than that defined by the loop of the center section.
