Abstract: The present invention relates to a method for direct reprogramming from somatic cells into pancreatic beta cells by using microRNA and small-molecule materials. The inventors of the present invention confirmed that, as a result of having attempted direct reprogramming upon co-treatment of microRNA and small-molecules (e.g., various differentiation-inducing materials), the expression level of PDX1 remarkably increased in pancreatic beta cells, and, when pancreatic beta-like cells were induced using such a method, direct reprogramming was performed with very high yield. In addition, since autologous cells are used, the present invention has the advantages of no occurrence of immune rejection responses and a low possibility of developing cancer, and thus is expected to be effectively used in the development of safer cellular therapeutic agents.

Abstract: In a software watermarking method according to an embodiment, a watermark is embedded into an executable binary file by compiling a source code to generate the executable binary file and rewriting the executable binary file while reordering two or more functions included in the executable binary file. At the time of compiling the source code, metadata including information related to positions of functions in the executable binary file is generated and included in the binary. The executable binary file is rewritten by reflecting change in positions of the two or more functions using the metadata without recompiling the source code. Information related to the changed function location is stored in a separate ledger.

Abstract: In a method of training a binarized neural network (BNN), a binarized weight set is generated by applying a clipping function to a weight set. Output data is generated by sequentially performing a forward computation on the binarized neural network based on input data and the binarized weight set. A gradient of the weight set is generated by sequentially performing a backward computation on the binarized neural network based on loss calculated from the output data. The binarized neural network is trained by updating the weight set based on the gradient of the weight set and changing a range of the clipping function.
