Abstract: A gate driver includes a first scan signal generator configured to output a logic voltage for driving of a scan transistor through a plurality of stages connected in cascade, the scan transistor performing a switching operation to transfer a data voltage to a driving transistor of a pixel, a second scan signal generator configured to output a logic voltage for driving of a sensing transistor through the plurality of stages, the sensing transistor sensing deterioration of a light emitting element of the pixel, a light emission control signal generator configured to output a logic voltage for control of a light emission control transistor of the pixel through the plurality of stages, and an initialization voltage generator driven by logic voltages received from some nodes of the first scan signal generator based on the light emission control signal generator to supply an initialization voltage to the pixel.

Abstract: An aqueous cellulose solution containing chitosan and/or chitosan derivatives, or alternatively alginic acid and/or alginic acid derivatives, and water-soluble and antibacterial rayon fiber produced from the cellulose solution. The aqueous cellulose solution includes a first component containing at least one selected from the group consisting of alkali cellulose and cellulose derivatives, and a second component containing at least one selected from the group consisting of soluble chitosan and chitosan derivatives, or alternatively at least one selected from the group consisting of soluble alginic acid and alginic acid derivatives, wherein the first and second components are homogeneously mixed without phase separation. The rayon fiber obtained by wet-spinning the aqueous cellulose solution shows antibacterial property or flame-retardancy depending on the composition of the cellulose solution, and water-solubility or water-resistance depending on the composition of a coagulating bath.

Abstract: An elastic water-permeable polymeric concrete composition, a formulation method therefor, an elastic water-permeable polymeric concrete structure using the composition, and a method for constructing the structure. The polymeric concrete composition is formulated by integrating a rubber powder ground from waste tires or waste rubber and an aggregate using a polymeric binder, and if required, by adding a pigment and aromatic capsules capable of providing remedial and psychological effects. The polymeric concrete structure manufactured using such polymeric concrete composition has appropriate elasticity, water permeability, strength and a pleasant aroma. Thus, the polymeric concrete composition is useful for paving a footpath, a roadway, a bikeway, a railway crossing, a parking lot, a stadium, a racing track, a landing strip, etc., and as a material for civil engineering and constructions such as blocks, tile sound-absorbing plates, soundproofing plates, soundproofing walls and retaining walls.

Abstract: A pre-treated rubber, a rubber solution and a rubber concrete using the pre-treated rubber or the rubber solution are described. Rubber products such as a rubber concrete manufactured by molding processing of the pre-treated rubber, a rubber solution prepared by dissolving vulcanized rubber in a chlorine-substituted hydrocarbon solvent, of compositions including the pre-treated rubber or the rubber solution, pebbles, sand, etc. have high strength and have good restraining effect on noise and vibration. Moreover, waste resources such as tires can be advantageously reused.
