Abstract: A method for restoring a blockchain network via synchronizations while maintaining a reliability on backup data and minimizing resource usage by converting identities of nodes adaptively is provided. The method includes steps of: (a) a specific delayed node among one or more delayed nodes in the blockchain network performing synchronization with the existing service nodes while the specific delayed node maintains a specific delay according to a specific initial setting thereof; (b) the specific delayed node, in response to acquiring the triggering command, allowing at least some of the existing service nodes to perform synchronization based on blocks included in the specific delayed node without the specific delay, to thereby convert the identity thereof into a new service node.

Abstract: An ultrasonic humidifier according to an embodiment of the present invention includes: a water bottle accommodating water capable of generating humidification; a water bottle lid covering an upper opening surface of the water bottle and including a humidification outlet for discharging the humidification; and an ultrasonic humidification generating module which floats submersibly in the water accommodated in the water bottle and generates humidifying particles by using ultrasonic waves.

Abstract: A floating-type humidifier container according to an exemplary embodiment of the present invention includes: a lower body having a space portion which is opened at an upper side thereof and accommodates water therein so that a floating-type humidifier floats on the water; and an upper body having an opening portion provided in an upper portion of the upper body so that one end of the floating-type humidifier is penetratively inserted into the opening portion, in which the upper body includes an inclined portion which is formed to be inclined downward toward a center of the space portion so that humidification particles discharged from the floating-type humidifier are introduced into the space portion through the opening portion.

Abstract: A floating humidifier using a vertical power transmission scheme according to an embodiment of the present disclosure includes: a wireless power transmitting unit including a substrate and a vertical structure vertically arranged on the substrate, and configured to transmit electric power in a magnetic induction scheme through the substrate and the vertical structure; a water container including an accommodation portion in which water is accommodated and a fastening portion protruding from a center of the accommodation portion and fitted in the vertical structure above the wireless power transmitting unit; and a humidification generating unit inserted into the fastening portion of the water container through a vertically penetrated fastening hole and configured to generate a current using a magnetic force induced by the wireless power transmitting unit to drive a humidifier.

Abstract: A display device including: a plastic window including a light transmittance film and a polymer layer, and a functional film including a touch screen panel film, a polarizing film, or a combination thereof. The light transmittance film, the polymer layer, and the functional film are sequentially stacked on each other, and the light transmittance film, the functional film, and the polymer layer are attached to each other by a plastic. A method of manufacturing the same is also provided.

Abstract: A rotary aspirator according to the present invention includes: a body portion which has a length in a front and rear direction, and has an outer circumferential surface formed as any one of a circular shape, an elliptical shape, and a polygonal shape in a lateral direction; a handle which is connected to a rear end of the body portion and has a smaller diameter than the rear end of the body portion so that a user moves the handle forward and rearward and rotates the handle in a state in which the user holds the handle by hand; and an absorbing member which is continuously and spirally wound in the front and rear direction of the body portion and absorbs nasal mucus of a target person.

Abstract: An air cleaner according to an exemplary embodiment of the present invention includes a water tank in which water is contained, a rotating shaft which is mounted in the water tank and rotates, and a rotating body which is coupled to the rotating shaft to rotate in a longitudinal direction of the rotating shaft as a rotational axis and formed with a plurality of rotating blades capable of collecting air, in which the rotating shaft is obliquely mounted to form a predetermined angle with a water surface formed by the water contained in the water tank.

Abstract: A floating type humidifier with an increased humidification amount according to an exemplary embodiment of the present invention includes: a floating body which floats on water accommodated in a water tub and has a hollow portion vertically and penetratively formed at a central portion of the floating body; an ultrasonic generator which is installed in the hollow portion and configured to atomize water, which is introduced at a lower portion, to create humidification particles by using ultrasonic vibration; a humidification particle guide unit which is installed on an upper portion of the floating body and guides the humidification particles so that the humidification particles move upward along a guide hole in the humidification particle guide unit; and an air pressurizing portion which is provided in the humidification particle guide unit and pressurizes air so that the humidification particles are moved upward by the pressurized air.
