    Abstract: Provided is a method for recognizing handwritten characters in a terminal through federated learning. In the method, a first common prediction model for recognizing text from handwritten characters input from a user is applied, the handwritten characters are received from the user, feature values are extracted from an image including the handwritten characters, the feature values are input to the first common prediction mode, first text information is determined from an output of the first common prediction model, the first text information and a second text information received from the user for error correction of the first text information are cached, and the first common prediction model is learned using the image including the handwritten characters, the first text information, and the second text information. In this way, the terminal can determine the text from the handwritten characters input by the user, and can learn the first common prediction model through a feedback operation of the user.

    Abstract: The present disclosure relates to an antibacterial glass composition and a manufacturing method thereof. The antibacterial glass composition according to the present disclosure comprises 20 to 40 wt % of SiO2; 5 to 25 wt % of B2O3; 15 to 25 wt % of one or more of Na2O, K2O and Li2O; and 25 to 45 wt % of CaO, preventing a deterioration in durability and having an excellent antibacterial property. Additionally, the present disclosure relates to an antibacterial glass composition and a manufacturing method of antibacterial glass powder using the same that is a novel silicate glass composition, is transparent and colorless and has an excellent antibacterial property and a high antifungal activation level, such that when the antibacterial glass composition is used as a coating agent of a glass shelf, an additive of a plastic injection molded product and the like, the antibacterial glass composition prevents the deformation of the exteriors of the glass shelf, the plastic injection molded product and the like.

    Abstract: The present invention relates to a wireless sound device and a control method thereof, in which at least one of sound volume adjustment and noise cancelling operation is appropriately selected according to a user's preference and/or situation so that noise according to an external ambient sound is reduced and a sound can be thus provided to the user. The present invention may provide a wireless sound device comprising: a wireless communication unit for performing wireless communication with a sound source device; a speaker for outputting a sound source signal received from the sound source device; an external microphone for picking up an ambient sound; an internal microphone for picking up an in-ear sound and internal noise; and a control unit for performing sound volume control and ANC control to reduce an influence of the internal noise, wherein the control unit performs control so that, when reduction in the internal noise is insufficient after one of the sound volume control and the ANC control is performed preferentially, the other of the sound volume control and the ANC control is further performed.
