Abstract: The present disclosure relates to a printed circuit board. The printed circuit board includes a plurality of insulating layers each having a plurality of concave portions; a plurality of conductor pattern layers disposed in a plurality of concave portions of each of the plurality of insulating layers; first and second via holes connected to one of the plurality of concave portions independently of each other and penetrating through at least two of the plurality of insulating layers independently of each other; and first and second via conductors disposed in the first and second via holes, respectively, and connecting two of the plurality of conductor pattern layers independently of each other. An average width of the first via conductor is greater than that of the second via conductor on a cross-section.

Abstract: A method for evaluating an adhesive strength of a separator including manufacturing an electrode-separator composite including an electrode stacked on at least one surface of a separator, and the at least one surface of the separator and a surface of the electrode facing the at least one surface include adhesive surfaces and non-adhesive surfaces, and the adhesive surfaces and the non-adhesive surfaces are alternately disposed; moving the electrode-separator composite; cutting the electrode-separator composite in a direction parallel to the moving direction; attaching measuring rolls respectively to both surfaces of the cut electrode-separator composite; separating the electrode-separator composite by rotating each of the attached measuring rolls and spacing the measuring rolls apart from each other; and measuring a torque generated by the measuring rolls while separating the electrode-separator composite.

Abstract: Disclosed is a game command recognition method and apparatus. The game command recognition apparatus receives a user input of text data or voice data and extracts a game command element associated with a game command from the received user input. The game command recognition apparatus generates game action sequence data using the extracted game command element and game action data and executes the generated game action sequence data.

Abstract: The present invention relates to a reinforcing material which is attached to a toecap embedded in a safety shoe so as to ensure the convenience and safety of a worker. The reinforcing material is combined with the toecap embedded in the safety shoe used generally so as to protect portions of an instep and toes of a worker, wherein a portion of the reinforcing material contacting with the instep is made of a flexible material such that a foot is comfortable during movement, and the reinforcing material having the portion made of the flexible material is combined with the safety shoe to effectively protect the foot, thereby improving the safety and efficiency of work performed by the worker.

Abstract: Embodiments of the inventive concept provide a successive gas hydrate manufacturing device, without hydration after generating gas hydrate slurry, capable of operating with a higher conversion rate and relatively low hydrate generation pressure and reducing a product cost by decreasing the number of processing steps for removing heat of reaction, for which the total exothermic value downs due to no need of latent heat according to a phase change rather than the case of generating a gas hydrate directly from a water solution, as well as making gas diffusion easier during reaction of generation and maximizing a contact area between water and gas to increase a gas capture rate and shorten the total hydrate generation time.
