Abstract: A storage device includes a printed circuit board (PCB) with attached semiconductor chips, each including a memory, and with at least one wire coupling the semiconductor chips. The storage device includes a case including a first case surrounding a top portion of the printed circuit board and a second case surrounding a bottom portion of the printed circuit board. A sidewall of the first case and a protrusion of the second case form a concavo-convex structure. The sidewall of the first case and the protrusion of the second case cover a side of the printed circuit board.

Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

Abstract: Disclosed herein is a method of printing a nanostructure including: preparing a template substrate on which a pattern is formed; forming a replica pattern having an inverse phase of the pattern by coating a polymer thin film on an upper portion of the template substrate, adhering a thermal release tape to an upper portion of the polymer thin film, and separating the polymer thin film from the template substrate; forming a nanostructure by depositing a functional material on the replica pattern; and printing the nanostructure deposited on the replica pattern to a substrate by positioning the nanostructure on the substrate, applying heat and pressure to the nanostructure, and weakening an adhesive force between the thermal release tape and the replica pattern by the heat.

Abstract: An optical inspection apparatus includes a stage that supports a target substrate, the target substrate including a plurality of light emitting elements, a jig that applies an electrical signal to the target substrate, the jig including a regulation resistor, a microscope that generates magnified image data of the target substrate, a camera that captures the magnified image data to generate a color image of the target substrate, and an optical measurement unit that captures the magnified image data of the target substrate to generate a spectrum image and measure optical characteristics of the target substrate.

Abstract: Disclosed herein is a method of depositing a transition metal single-atom catalyst including preparing a carbon carrier, and depositing a transition metal single-atom catalyst on the carbon carrier, in which the carbon carrier is surface-treated by an oxidation process, and wherein the deposition is carried out by an arc plasma process.

Abstract: There is provided a card adapter including: a printed circuit board that is provided with a connector connected to an external data processing apparatus at one end thereof; a housing for accommodating the printed circuit board therein, and for exposing and fixing the connector at one side thereof; contact elements which are arranged adjacent to an end opposite to the side at which the connector of the printed circuit board is provided, and are electrically connected with a circuit device of the printed circuit board; and a card holder which is fixed adjacent to the contact elements such that the card is inserted into, and fixed to, the holder to be electrically contacted with the contact elements.

Abstract: A method of processing a caption for a digital video disk (DVD) includes loading a prepared caption script of a predetermined language in a caption indicator, showing a moving picture corresponding to the caption script and ascertaining the caption generation point and caption annihilation point of the shown moving picture, writing time codes corresponding to the caption generation point and the caption annihilation point and displaying a list of caption scripts and a list of time codes on the caption indicator, checking the state of the time codes and the state of a corresponding caption displayed, and correcting the state of the time codes and the state of the corresponding caption displayed, and correcting the state of the time codes and the state of the corresponding caption displayed if an error is detected, and producing the caption scripts and the time codes in a scrip file.
