Abstract: An apparatus for adjusting a seat of a vehicle includes a seat back frame, a cushion frame that is moved forward and backward by a motor driving unit, a cushion hinge part connecting the seat back frame and the cushion frame and rotating according to the movement of the cushion frame to adjust the angle of the seat back frame, and a seat back hinge part connecting the seat back frame and the vehicle body and rotating according to the movement of the seat back frame.

Abstract: A railess variable seatback type rear seat includes: a linear movement device configured to convert a rotation of a motor into a linear movement; a sliding movement device configured to convert the linear movement into a sliding movement in which a seat cushion is pushed forward or backward; and a reclining angle change device configured to convert the sliding movement into a reclining movement, and to fold a seatback, which is connected to the seat cushion, forward or to recline the seatback backward.

Abstract: Various example embodiments of the disclosure relate to an electronic device and a wireless communication connection control method thereof.

Abstract: There is provided a method of preparing a fluorescent silk fibroin solution, which includes a) obtaining scoured fluorescent silk fibroin by adding transgenic fluorescent silkworm cocoons to an aqueous solution including a scouring agent, heating the transgenic fluorescent silkworm cocoons at 40 to 60° C. for 8 to 24 hours and washing the transgenic fluorescent silkworm cocoons with distilled water, b) dissolving the scoured fluorescent silk fibroin at 40 to 60° C. for 1 to 5 hours in a solvent in which 15 mg to 1.5 g of dithiothreitol (DTT) is mixed per 100 mL of 9 to 9.6 M LiBr, and c) dialyzing the dissolved fluorescent silk fibroin in single distilled water for 48 to 96 hours. The scouring agent includes an alcalase and sodium hydrogen carbonate (NaHCO3). The conventional methods of preparing a silk fibroin solution from fluorescent silkworm cocoons have drawbacks in that silk fibroin is not dissolved at a low temperature and fluorescence is lost.
