Abstract: An electronic device includes a housing, a slot disposed in an interior of the housing, wherein the slot is configured to permit an electronic module inserted into the slot, a cooling member disposed outside the slot to cool the electronic module, and a heat transfer member configured to be connected to the electronic module to transfer heat from the electronic module to the cooling member.

Abstract: A semiconductor memory device includes gate electrodes arranged on a substrate to be spaced apart from each other in a first direction perpendicular to an upper surface of the substrate, an upper insulation layer arranged on an uppermost gate electrode, channel structures penetrating through the upper insulation layer, and the gate electrodes in the first direction, and string selection line cut insulation layers horizontally separating the upper insulation layer and the uppermost gate electrode. Each of the string selection line cut insulation layers includes a protrusion protruding toward the uppermost gate electrode and positioning on the same level as the first gate electrode.

Abstract: The present invention relates to a method for providing information on an object excluded in a visual field of a terminal in a form of augmented reality (AR) by using an image inputted to the terminal and information related thereto. The method includes the steps of: (a) specifying the visual field of the terminal corresponding to the inputted image by referring to at least one piece of information on a location, a displacement and a viewing angle of the terminal; (b) searching an object(s) excluded in the visual field of the terminal; and (c) displaying guiding information on the searched object(s) with the inputted image in a form of the augmented reality; wherein the visual field is specified by a viewing frustum whose vertex corresponds to the terminal.
