Abstract: The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. By comprising the compound according to the present disclosure, it is possible to produce an organic electroluminescent device having improved driving voltage, power efficiency, and/or lifetime properties compared to the conventional organic electroluminescent devices.

Abstract: Provided is a method for manufacturing a water-treatment membrane, the method including bringing an aqueous solution including free chlorine and a halogen ion into contact with a polyamide active layer, wherein the free chlorine is present in an amount from 150 ppm to 400 ppm and the halogen ion is present in an amount from 150 ppm to 400 ppm based on the aqueous solution, and a water-treatment membrane manufactured using the same.

Abstract: A pressurizing centrifugal dehydrator for removing moisture according to the present disclosure includes: an inner basket into which slurry is introduced; an outer basket surrounding the inner basket; a blocking barrier disposed in the outer basket; and a gas supplying portion for supplying gas into the inner basket and/or the outer basket, wherein a dehydration product is positioned between an outer circumference of the blocking barrier and an inner side of the outer basket to maintain airtightness of the outer basket.

Abstract: Disclosed is a cushion tip-up type seat for a vehicle. The cushion tip-up type seat for a vehicle is configured to perform a tip-up function of a cushion part, and to move a seat leftward and rightward to adjust an interval between left and right seats, whereby left and right spacing between occupants seated in the seats is sufficiently secured and the convenience of the occupants is improved.

Abstract: Disclosed is a water-soluble coating composition, which is applied on the surface of fuel rods to prevent scratching of the surface of the fuel rods upon manufacturing a nuclear fuel assembly for light water reactors. This water-soluble coating composition facilitates the formation and removal of a coating film and the resulting coating film can exhibit strength and durability equivalent to those of an existing lacquer (nitrocellulose) coating film, and can thus be used as an alternative to lacquer, thereby easily removing the coating film and improving workplace safety, ultimately achieving improvements in the working environment and high workplace safety.
