Abstract: The present invention relates to a method for manufacturing a lithium secondary battery separator comprising the following steps: a step of surface-modifying inorganic particles using a coupling agent; a step of mixing the surface-modified inorganic particles with a polymer; and a step of irradiating an electron beam to the mixed inorganic particles and polymer. The method for manufacturing a lithium secondary battery separator provided in one aspect of the present invention has an effect that a lithium secondary battery separator having improved mechanical and thermal properties can be manufactured.

Abstract: Provided is a computer system for providing a tactile interface for a real-time two-dimensional (2D) tactile input/output interaction of a visually impaired person and an operating method thereof. The computer system may be configured to generate a tactile output corresponding to 2D visual information for a first body surface of a user through a tactile output module that is in contact with the first body surface, sense a tactile input for a second body surface of the user through a tactile input module, and generate a control signal for the 2D visual information based on the tactile input. Here, one of the first body surface and the second body surface may be a ventral surface of one body portion of the user, and the other one of the first surface and the second body surface may be a dorsal surface corresponding to the ventral surface in the one body portion.
