Abstract: Provided is a method of evaluating electrode quality, which includes: providing a plurality of electrodes which include a current collector and an active material layer formed on the current collector and have not been roll-pressed; measuring a color coordinate value of the active material layer of each of the plurality of electrodes using an optical instrument and calculating an average value; and evaluating the electrodes as good products when a difference between the color coordinate value measured from the individual electrodes and the average value is no more than a predetermined value and as defective when the difference exceeds the predetermined value.

Abstract: Disclosed is a headrest device for a vehicle. The headrest device may include a stationary headrest portion coupled to a seatback of the vehicle and formed to extend upwards. The stationary headrest portion may be located at a rear of a head of an occupant. The headrest device may include a movable headrest portion coupled to the stationary headrest portion so as to be slidable in a vertical direction, the movable headrest portion may be located in front of the stationary headrest portion. The headrest device may include an actuator including a first side coupled to the fixed part, and a second side coupled to the movable headrest portion. The actuator may be configured to cause the movable headrest portion to slide in the vertical direction.

Abstract: An atomic layer etching method using a ligand exchange reaction may include a substrate providing step of putting a substrate with a thin film formed thereon into a reaction chamber, a halogenated thin film forming step of forming a halogenated thin film on a surface of the thin film by infusing a halogenated gas into the reaction chamber, and an etching step of etching the halogenated thin film by infusing a ligand without a metal or metal precursor into the reaction chamber with the substrate with the halogenated thin film.

Abstract: Disclosed is a method and system for automatic establishment of an optimal schedule for a construction project. The disclosed method of automatic establishment of an optimal schedule for a construction project is a computer-implemented method of automatic establishment of an optimal schedule for a construction project, the method including: providing project data, standardized schedule data, and characteristic data (S10); generating project schedule data by combining the project data, the standardized schedule data, and the characteristic data (S20); and deriving an optimal project schedule by processing the project schedule data through a scheduling optimization algorithm (S30).

Abstract: A rolling boot used in a constant velocity joint includes: a first fastening portion that is configured to be fastened to a joint shaft of the constant velocity joint; a second fastening portion that is configured to be fastened to a joint case of the constant velocity joint; a first folding portion that is configured to be folded when the constant velocity joint is articulated; a second folding portion that is configured to be folded when the constant velocity joint is articulated and is disposed radially outside the first folding portion; a support portion that is configured to support tensile and compression when the first folding portion and the second folding portion are folded; a first peak connecting the first fooling portion and the second folding portion; and a second peak connecting the second folding portion and the support portion.

Abstract: Provided are a display apparatus and a method of controlling the display apparatus, the method including providing one or more input windows for receiving an input of identification (ID) values from a user, determining whether one or more ID values respectively input to the one or more input windows match with pre-registered registration values, and changing an error input window from among the one or more input windows by applying an animation effect to the error input window in which an ID value from among the one or more ID values does not match with the registration values.
