Abstract: A disclosed polymer thin film includes a cationic polymer having a hydrolyzable side chain. The polymer thin film has a surface potential of 1 mV to 50 mV. A hydrolysis efficiency of the cationic polymer is 30% or more after reaction at 50° C. for one hour. The cationic polymer is dissolved to three-dimensionally capture nucleic acids, and releases the nucleic acids through hydrolysis. Thus, nucleic acid capturing-releasing efficiency can be improved.

Abstract: Disclosed is a color tunable organic light emitting diode based on a photonic crystal structure. The color tunable organic light emitting diode includes at least one substrate, an anode and a cathode provided on the substrate, a photonic crystal layer provided between the anode and the cathode, and at least one emission layer provided on the photonic crystal layer, wherein a plurality of patterns are formed by a plurality of photonic crystals included in the photonic crystal layer, the photonic crystal layer is configured to be stretchable by a strain applied to the photonic crystal layer in a diagonal direction, and the at least one emission layer is configured to emit light of a specific color according to the plurality of patterns deformed by the strain.

Abstract: A magnetic drive system is disclosed. The magnetic drive system comprises: a first magnetic field generation unit; a second magnetic field generation unit which is disposed under the first magnetic field generation unit in a Z-axis direction with an operation area interposed therebetween, and generates a magnetic field in the operation area in combination with the first magnetic field generation unit; and a moving module for moving at least one of the first magnetic field generation unit and the second magnetic field generation unit.

Abstract: A ventilated shoe is provided. The ventilation shoe includes a bottom pad (10) with a peripheral wall (11) that has a front part (12), a rear part (13), a right side part (14) and a left side part (15). A plurality of right and left side holes (142, 152) are formed in the right and left side parts (14, 15) of the peripheral wall (11). A ventilation pad (20) is disposed on the bottom pad (10) to be surrounded by the peripheral wall (11), in a wave-like layer with alternate crests (21) and troughs (22), forming a plurality of tunnel vaults (23) each of which extends from the right side part (14) to the left side part (15). A right belt (30) and a left belt (40) are disposed on the right and left side parts (14, 15) of the peripheral wall (11) to be slidable between two positions.

Abstract: The footpad of the present invention has multiple holes through which air flows to ventilate a wearer's feet while the wearer walks, runs, or jumps. The present invention provides sufficient support to the wearer and traction control to be used as the sole in a shoe or sandal. The present invention has a belt that slides to open or restrict the multiple holes through which air flows to ventilate the feet. Thus, for example, the wearer can open the holes for ventilation during warm weather and close the holes to restrict ventilation during cold weather.

Abstract: The footpad of the present invention has multiple holes through which air flows to Ventilate the bottom of the wearer's feet while the wearer walks, runs, or jumps. The present invention provides sufficient support to the wearer and traction control to be used as the sole in a shoe or sandal. The top face of the present invention has a plurality of unique channels that promote air ventilation across the bottom of the wearer's feet.

Abstract: A seat pad that is injection molded out of plastic with various combinations of holes and pathways that promote air flow to ventilate and prevent the build-up of perspiration on a person's back, upper legs, and rear end as they sit on it for an extended period of time. The seat pad also has multiple beads that provide acupuncture-type pressure for relaxation and comfort of the person. The design of the seat pad is such that it provides some flexibility for cushioning effect and some rigidity so that it is not collapsed or crushed under the weight of the person sitting on it for an extended period of time.
