Abstract: The present invention relates to a method and an apparatus for synthesizing the voice based on brain waves during imagined speech. The method for synthesizing the voice based on brain waves during imagined speech according to an embodiment of the present invention may include the following steps: a step to obtain the user's brain waves during imagined speech; a step to convert the above-mentioned brain waves of imagined speech into embedding vectors; a step to generate the mel-spectrograms based on the above-mentioned embedding vectors; a step to generate the voice using the above-mentioned mel-spectrograms; a step to output the above-mentioned voice.

Abstract: An electrostatic chuck is provided. An electrostatic chuck is implemented by comprising a silicon nitride sintered body and an electrostatic electrode embedded in the silicon nitride sintered body. Therefore, the electrostatic chuck includes a ceramic sintered body, which is silicon nitride, to have excellent plasma resistance, chemical resistance and thermal shock resistance while exhibiting heat dissipation performance of a level equivalent or similar to that of an aluminum nitride ceramic sintered body, which has been conventionally and widely used, and thus can be widely used in a semiconductor process.

Abstract: Disclosed is an apparatus for performance improvement in multimodal communication according to one embodiment of the present invention.

Abstract: Disclosed are novel compounds of Chemical Formula 1, optical isomers of the compounds, and pharmaceutically acceptable salts of the compounds or the optical isomers. The compounds, isomers, and salts exhibit excellent activity as GLP-1 receptor agonists. In particular, they, as GLP-1 receptor agonists, exhibit excellent glucose tolerance, thus having a great potential to be used as therapeutic agents for metabolic diseases. Moreover, they exhibit excellent pharmacological safety for cardiovascular systems.
