  • Publication number: 20210403996
    Abstract: Disclosed is a composition for diagnosing, preventing or treating drug addiction based on synaptotagmin binding cytoplasmic RNA interacting protein (SYNCRIP). SYNCRIP or a gene encoding the protein can be used to diagnose drug addiction. In addition, a therapeutic agent for drug addiction can be discovered by measuring the expression of SYNCRIP. Furthermore, an agent expressing SYNCRIP or promoting the activity of SYNCRIP can be used to prevent or treat drug addiction.

  • Publication number: 20210329307
    Abstract: Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.
