Abstract: A method for training an analysis model according to an embodiment includes receiving synthetic data for original data from a client apparatus, determining a hyperparameter value for analysis model training using the synthetic data, receiving a ciphertext for the original data from the client apparatus, and training the analysis model using the determined hyperparameter value and the received cipher text.

Abstract: A button-type secondary battery includes a lower can having a bottom surface; an upper can having a top, the upper can and the lower can being coupled to define a space therein; an electrolyte in the space; an electrode assembly in the space and including a negative electrode, a separator, and a positive electrode wound together; a gasket between the upper can and the lower can to electrically insulate the upper and lower cans; a top insulator that is electrically insulating and covering a top surface of the electrode assembly; and a bottom insulator that is electrically insulating and covering a bottom surface of the electrode assembly. The top and bottom insulators are each configured to expand in volume by absorbing the electrolyte. Surfaces of at least one of the top insulator and the bottom insulator are coated with a protective layer to prevent thermal shrinkage from occurring.

Abstract: A button type secondary battery includes a wound electrode assembly; a lower can with the electrode assembly and an electrolyte in the lower can; a top plate to close the lower can; a positive electrode terminal coupled to the top plate through a gasket to be electrically insulated from the top plate with a portion of the positive electrode terminal passing through a hole in the top plate to be bonded to a positive electrode tab; a top insulator covering a top surface of the electrode assembly; and a bottom insulator covering a bottom surface of the electrode assembly. The top insulator and the bottom insulator are each configured to expand in volume by absorbing the electrolyte. Surfaces of at least one or more of the top insulator and the bottom insulator are coated with a protective layer configured to prevent thermal shrinkage from occurring.

Abstract: The present invention relates to a pharmaceutical composition for prevention or treatment of neurological diseases and mental diseases, the composition containing syringaresinol. The syringaresinol according to the present invention has an effect of reducing excitatory synaptic transmission in a central nervous system and an effect of suppressing epilepsy and activity of animals. This suppressive effect of the excitatory synaptic transmission may be effectively used for the prevention and treatment of all neurological diseases and mental diseases resulting from synapse dysfunction and synpatic excitatory-inhibitory transmission imbalance.
