Abstract: A free motion headform (FMH) impact performance prediction device using artificial intelligence includes a data processing processor configured to generate an image by extracting a pre-processed test target image, generated by pre-processing test target design data, using a pre-trained model and generate a pre-processed test target distance value by pre-processing the test target design data. The FMH input performance prediction device also includes a machine learning processor configured to concatenate the image generated by extraction on the basis of the pre-trained model and the pre-processed test target distance value and to predict impact performance using a neural network in which parameters are updated by learning based on an image obtained by pre-processing existing design data and existing impact amount data corresponding to the existing design data. The FMH input performance prediction device further includes an output processor configured to output a value learned by the machine learning processor.

Abstract: The present disclosure relates to a length-adjustable pole. A length adjusting pole is installed inside a main pole to be able to extend and shorten vertically, and at the same time, a length adjusting member is installed inside the length-adjustable pole so that a user can extend and shorten the length adjusting pole to a desired length with a simple action.

Abstract: Provided are a method for preparing a polyetherketoneketone and a polyetherketoneketone prepared thereby, wherein, at the time of a polymerization reaction, nitrogen gas is blown into a liquid reaction medium while stirring, thereby quickly removing hydrochloric acid, which is a by-product generated during the reaction, and preventing aggregation of resin particles, thus suppressing the generation of scales.

Abstract: A method of manufacturing a multilayer electronic component includes forming a stack by stacking a plurality of ceramic green sheets on which conductive patterns are disposed on a support film, cutting the stack in a second direction, perpendicular to a first direction which is a stacking direction of the plurality of ceramic green sheets, cutting the stack in a third direction, perpendicular to the first and second directions, to obtain a plurality of unit chips, separating the unit chip from the support film, arranging the unit chip such that one of side surfaces of the unit chip is in contact with an adhesive tape, and attaching another one of the side surfaces to a ceramic green sheet for a side margin portion, and forming a side margin portion on the another one of side surfaces.
