Abstract: The present invention relates to a chemical cross-linking based porous material for tissue regeneration and hemostasis, including an extracellular matrix of decellularized kidney tissue, and a method for production thereof. The porous material including an extracellular matrix of decellularized kidney tissues according to the present invention forms a chemical cross-linking bond, while the final product does not contain any existing cross-linking agent component, whereby the porous material can be utilized in biocompatible substances. Further, the porous material of the present invention does not only have rapid hemostasis but also delays degradation in a long term to thus exhibit tissue regeneration effects, so that the porous material is expected to be usefully applicable for treatment of different diseases due to tissue damage in a variety of tissues, or for hemostasis and tissue regeneration at removal of tissues or incision operation.

Abstract: Provided are a computing device and method for assigning a generator to a semiconductor layout and a method of training a neural network. The former method includes an input operation of receiving a layout by a computing device, a division operation of dividing the layout into a plurality of channels, a conversion operation of converting each of the divided channels into a matrix, and an inference operation of inferring a generator to be assigned to the layout from the matrix. The inference operation is performed by displaying one or more generator candidates corresponding to the received layout. The assignment operation is performed by assigning a generator to the received layout based on the probability results of the inference operation.
