Abstract: The present invention relates to a non-aqueous electrolyte solution for a secondary battery, and a secondary battery comprising same. Adding a compound represented by chemical formula 1 or chemical formula 2 to a non-aqueous electrolyte solution for a secondary battery according to the present invention has the effect of improving room-temperature and high-temperature thermal stability characteristics, and high-temperature storage characteristics.

Abstract: Provided are a method of processing images and an electronic device thereof. The electronic device includes a memory and a processor operatively connected to the memory. The processor is configured to divide an image into a plurality of sub images, load information about a first sub image of the plurality of sub images into the memory, perform image processing on the first sub image, load information about an image area that does not overlap with the first sub image of a second sub image located in a longitudinal direction of the first sub image into the memory, and perform image processing on the second sub image.

Abstract: An image forming method, and an image forming apparatus to perform same, including connecting a portable storage medium to the image forming apparatus, selecting at least one file stored in the portable storage medium, disconnecting the portable storage medium from the image forming apparatus, and performing a job corresponding to the at least one selected file in response to the portable storage medium being disconnected from the image forming apparatus.

Abstract: An image forming apparatus capable of satisfying various desires of a user by providing the user with psychological stability, a printing system including the same, and a method of controlling the image forming apparatus and the printing system. The method of controlling the image forming apparatus includes detecting characteristic information of print data, and reproducing multimedia content corresponding to the characteristic information of the print data during a printing process of the print data.

Abstract: A mold for molding plastic products includes a fixing plate and a moving plate which is movable toward and away from the fixing plate. The fixing plate and the moving plate include respective cavity-forming portions which form a cavity into which a melted plastic is injected so as to form a molded product. A plurality of molding pins is provided having prominence-depression portions positionable in the cavity for forming undercut portions in the molded product, the molding pins being slidable through the moving plate by an eject plate. The molding pins pass obliquely through the moving plate so that as they slide therethrough, their prominence-depression portions are separated from the undercut portions of the product. Two of the molding pins form on the product a partition wall having undercut portions at opposite sides thereof. Those two molding pins cross over one another so that the prominence-depression portions thereof face each other, with no part of the cavity-forming portions situated therebetween.
