Abstract: The present disclosure relates to managing a document to be cleaned, includes processing a request, in response to the request to store document data of a first document in a database, based on at least one of whether the first document is duplicate or whether substantive contents of the first document are a same in a relationship with a second document pre-stored in the database, whether the first document is duplicate may be determined by comparing a unique identification value and version information of the first document with a unique identification value and version information of the second document, and whether substantive contents of the first document are the same may be determined by comparing hash data of the first document with hash data of the second document.

Abstract: The present disclosure relates to a catalyst for a fuel cell electrode including an active particle which includes a core comprising platinum, a transition metal excluding platinum, and an oxide of a non-transition metal; and a shell disposed on the core and including platinum, wherein the active particle includes platinum and the non-transition metal in a molar ratio of 100:1.80 to 100:4.00, a method of preparing the same, and a fuel cell including the same.

Abstract: Provided are a light-emitting diode structure and a light-emitting diode manufacturing method. The light-emitting diode manufacturing method comprises the operations of: preparing a lower substrate, which includes a substrate and a separation layer formed on the substrate, and preparing at least one semiconductor rod, which is formed on the separation layer, forming a rod structure, which includes a rod protecting layer formed on the separation layer to surround the at least one semiconductor rod and an auxiliary layer formed on at least part of the rod protecting layer and separating the rod structure from the lower substrate by removing the separation layer, and separating the at least one semiconductor rod from the rod structure.

Abstract: A seat for a vehicle, includes a second row center seat and a second row side seat provided on a partition wall positioned rearward of a driver seat, the second row center seat may move leftward or rightward, and an interval between the seats may be increased in a state in which the second row center seat is moved in a right direction away from the second row side seat, which makes it possible to maximally prevent body contact between a passenger in the second row center seat and a passenger in the second row side seat.

Abstract: The present disclosure relates to a vehicle rear seat including: a center seat; and side seats located on the left and right of the center seat, wherein, the center seat is capable of protruding by moving the center seat forward with respect to the side seats, and in the state in which the center seat protrudes forward, it is possible to increase an inter-passenger distance so that physical contact between the passenger of the center seat and the passenger of each of the side seats can be prevented as much as possible.

Abstract: A display device and an operating method thereof are provided. The display device may include: a display; a camera; a memory configured to store one or more instructions; and a processor configured to execute the instructions to obtain an image captured by the camera, transform the image based on visual condition information of a user, the visual condition information including information about a type of visual impairment of the user, and display the transformed image on the display.

Abstract: Provided is a device including: a controller configured to obtain illumination information about illumination around the device, determine, based on the illumination information, a thickness of an outline of an object included in content reproduced by the device, and perform image processing on the content such that the outline of the object is represented as having the determined thickness; and a display displaying the content on which the image processing is performed.
