Abstract: The present invention relates to a composition which is for preventing and ameliorating or treating premenstrual syndrome symptoms, and includes: (a) a Chrysanthemum zawadskii extract; (b) a mixture of the Chrysanthemum zawadskii extract and a malt extract; or (c) a mixture of the Chrysanthemum zawadskii extract, the malt extract, and an aloe extract. Specifically, the present compositions effectively inhibit the secretion of prolactin from pituitary cells, which is a phenomenon that appears during premenstrual syndrome, thereby increasing the secretion of progesterone, which is reduced during the luteal phase of women, and can thus be advantageously used as a composition for preventing and ameliorating or treating women's premenstrual syndrome.

Abstract: The machine learning method for a LiDAR-based deep learning object perception apparatus comprises preparing an original dataset of a LiDAR point cloud; acquiring virtual object datasets from a point cloud database; adding the virtual object datasets to the original dataset based on an association of position information for each object to acquire a learning dataset; and training the LiDAR-based deep learning object perception apparatus using the learning dataset.

Abstract: A seat for a vehicle includes support links enabling a rotating motion and a sliding motion between a seat frame and seat rails, the support links being mounted so that the seat may be rotated in the forward and rearward directions as in a seesaw motion about a shaft of the vehicle in a width direction of the vehicle, so as to easily implement a facing mode posture, in which passengers sit facing each other, a relaxed comfort posture, etc.

Abstract: A damper for a vehicle seat includes a vibrating mass member assembly including a vibrating mass member and a fixing member protruding from a side of the vibrating mass member, a guide bush accommodating the fixing member therein, coupled to each of the both sides of the vibrating mass member, and guiding the vibrating mass member to move in all directions, and a mounting bracket having an insertion hole into which the guide bush is inserted and fixedly formed on the vehicle seat. The damper may include an additional fixing member protruding from another side of the vibrating mass member, such that the fixing member and the additional fixing member protrude from both sides of the vibrating mass member.

Abstract: The present disclosure provides a seat cushion extension device for a fold-and-dive seat. The seat cushion extension device may include a pair of seat cushion side frames arranged at a predetermined interval, a seatback frame rotatably connected to the pair of seat cushion side frames and having a guide pin formed on an outer surface thereof, a seat cushion frame, a pair of links rotatably connected between the pair of seat cushion side frames and a front end of the seat cushion frame, and a pair of extension frames. Each of the pair of extension frames may have a front end connected to the seat cushion frame, and a rear end formed with a guide hole, into which a guide pin may be inserted. The seat cushion extension device may facilitate a forward extension of a seat cushion regardless of a position of a seatback of the fold-and-dive seat.

Abstract: The present disclosure relates to a fiber for manufacturing a stretchable hydrophobic fiber article, the fiber including silica nanoparticles which are surface-modified such that the silica nanoparticles include a hydrocarbon chain, and a styrene-based thermoplastic elastomer, a stretchable hydrophobic fiber article manufactured therefrom, and a manufacturing method thereof.
