A laser processing method includes irradiating a laser light into a substrate along a cutting line to form a laser-scribed layer within the substrate, irradiating an X-ray onto a first surface of the substrate along the cutting line, obtaining an image of a diffracted X-ray from the substrate, and determining whether or not the laser-scribed layer is formed along the cutting line, based on analysis of the obtained image of the diffracted X-ray.

A method for managing multimedia data by a contents server comprises the steps of: generating one or more chunks from an input image; generating chunk information of the input image including a list of the generated chunks; performing an identity check among chunks on the basis of the chunk information of the input image and chunk information stored in the contents server; and updating the stored chunk information according to a result of the identity check, wherein the chunks are a meaningful scene unit in an image.

A multi-pattern matching algorithm may be provided that includes: a moving step of moving a moving window from the start of a string one byte by one byte; a DFchecking step of converting the string on a current position of the moving window into an integer value, and of checking whether or not a bit of a related position in a first direct filter DFfor patterns having lengths larger than 2 bytes is set to; a DF moving step of checking one or more direct filters DF when the bit is set toaccording to the DFchecking step; a re-moving step of moving the moving window by one byte again when the bit of a related position in the direct filter DF, which has been checked lastly, is 0; and a terminating step of checking whether the moving window is located at the end of the string or not, and of terminating the algorithm when the moving window is positioned at the end of the string.
