Abstract: The present invention relates to a method for providing a correction alarm in a continuous biometric information measurement system and, more particularly, to a correction alarm method comprising: calculating the next correction time on the basis of an actual correction time of a user, thereby informing the user of the next correction time calculated on the basis of the actual correction time even if correction is performed differently from that of a preset correction period; and dividing a total use period of time of a sensor into a plurality of correction sections and differently calculating the next correction time on the basis of a correction section, to which a time at which an actual reference biometric value is input belongs, from among the plurality of correction sections, so as to use a reference biometric value input at every correction time, thereby accurately correcting a biometric value.

Abstract: The present invention relates to a method for correcting biometric signals in a continuous biometric information measurement system and, more specifically, to a method which, if a correction parameter is unstable when a correction factor is being calculated using a reference biometric value, does not use the current correction factor calculated from a reference biometric value as-is, but revises the current correction factor by applying, to the current correction factor, a compensation value calculated from the difference between the current correction factor and a previous correction factor, and thus even if a correction parameter is unstable it is possible to calculate a corrected biometric value by accurately correcting a biometric signal.

Abstract: The disclosure relates to a mask assembly and a method of manufacturing the mask assembly. A mask assembly includes a frame including a frame opening, and an open mask including cell openings overlapping the frame opening. The open mask further includes support portions overlapping remaining cell openings except a first cell opening among the cell openings.

Abstract: The present invention relates to a method for providing a calibration alarm in a continuous biometric information measurement system, and more particularly, to a calibration alarm method, wherein the next calibration time is calculated on the basis of an actual calibration time of a user so that the next calibration time calculated on the basis of the actual calibration time can be notified to the user even if the calibration is performed differently from a preset calibration cycle, and contextual information of the user is considered and a calibration alarm is provided according to the contextual information of the user so that the user can conveniently input a reference biometric value.

Abstract: The invention relates to a method capable of enhancing both the antifouling properties of a high entropy alloy and also the mechanical properties thereof, without using chemical substances such as antifouling paints to prevent the attachment of animals and plants such as barnacles, mussels, sea lettuces, diatoms, etc., the method according to the invention being characterized by the use of severe plastic deformation to reduce the grain size in a high entropy alloy and thereby impart to the high entropy alloy a property of suppressing the attachment of aquatic or marine organisms, and according to the method, environmental issues caused by the use of antifouling paint, which is conventionally the most widely used method, may be resolved, and the energy efficiency of ships may be improved, thereby reducing societal and economic loss.
