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 invention relates to a microbial insecticide for control of thrips, comprising a Beauveria bassiana ERL836 strain (KCCM11506P) or a spore thereof. The insecticide of the present invention shows an insecticidal activity as potent as pre-existing chemical insecticides against thrips, is environmentally friendly, and easy to manage and produce, thus finding outstanding commercial applications.

Abstract: A serial/parallel selective converter is provided that selectively receives and outputs data by using a plurality of serial input/output switching latches and a plurality of parallel input/output switching latches. The serial/parallel selective converter can further include three sets of transmission gates respectively coupling the plurality of serial input/output switching latches and the plurality of parallel input/output switching latches. The serial/parallel selective converter can output a serial input data signal as a parallel data signal and can also output a parallel input data signal as a serial data signal based on a serial/parallel selection control signal.
