Abstract: Disclosed is an operation method of a memory device which includes a plurality of memory cells stacked in a direction perpendicular to a substrate and a plurality of word lines respectively connected with the plurality of memory cells. The method includes applying a 0-th pass voltage to a first selected word line among the plurality of word lines and applying a first pass voltage to a first upper adjacent word line among the plurality of word lines, during a first word line setup period, and applying a first program voltage to the first selected word line and applying a second pass voltage smaller than the first pass voltage to the first upper adjacent word line, during a first program execution period after the first word line setup period. The first upper adjacent word line is a word line physically adjacent to the first selected word line.

Abstract: The present invention relates to a core-shell network structure formed using a biocompatible biopolymer and to a composition comprising same. Said structure can be used as an alternative to synthetic chemical materials, such as polyethylene glycol (PEG), to effectively disperse an insoluble effective substance within a composition, thus addressing safety issues, and formulations can be preserved stably for a long time through said network structure. Furthermore, said structure and the composition comprising same may provide useful benefits for the skin in terms of skin barrier enhancement, skin moisturization, skin regeneration, or the like.

Abstract: A washing machine includes a first washing tub, and a second washing tub detachably coupled to the first washing tub. The second washing tub includes a container containing laundry, a lower cover coupled to a top of the container and having an inlet configured to receive a water stream moving upwards in the container when the first washing tub rotates, and an upper cover coupled to a top of the lower cover and having an opening for putting the laundry into the container. A flow path is provided between the lower cover and the upper cover to discharge the water stream introduced through the inlet to an outside of the second washing tub. A slide lock is provided on the upper cover, movable between a binding position and an unbinding position, bound to the lower cover in the binding position, and separated from the lower cover in the unbinding position.

Abstract: A drum of a washing machine, which is configured to receive laundry and to perform washing or dehydration, includes a circumferential surface that defines a plurality of first patterns that protrude from the circumferential surface toward an interior of the drum, a second pattern that is recessed from the circumferential surface toward an exterior of the drum and that is surrounded by the plurality of first patterns, and a through hole located at the second pattern.

Abstract: A pet care device may include a head having a sterilizer and a handle extending from the head. The head may be formed of an outer body and an inner body positioned in an inner region of the outer body. A first space may be formed between the outer body and the inner body in which the sterilizer is provided. The sterilizer may include at least one light emitting device, and a light device may cover the first space. A second space partitioned from the first space may be at least partially located inside the inner body. Hair and/or debris may be collected in the second space.

Abstract: A washing machine includes a drum rotated about a vertical axis, and opened at a top thereof, a ring-shaped balancer coupled to an upper end of the drum, and a container detachably coupled to the balancer to contain laundry. The container includes a container body opened at a top thereof, and containing the laundry therein, and a plurality of threads protruding from an outer surface of the container body, extending long in a vertical direction, and arranged in a circumferential direction. Each of the threads is formed such that heights from valleys to roofs are gradually increased in a direction from bottom to top. The balancer includes engagement grooves formed on a ring-shaped inner circumference thereof to engage with the plurality of threads.

Abstract: A pet care device may include a removable or swappable care tool mounted on a head. The head may include a sterilizer and a sensor to determine what kind of care tool is mounted. A controller may identify the type of care tool mounted on the head based on a sensing value of the sensor and control the sterilizer based on the identified care tool.

Abstract: Polyelectrolyte microcapsules, and methods for making and using the polyelectrolyte microcapsules, are described. A method of making polyelectrolyte microcapsules includes forming an “interfacial complexation in emulsion” (ICE), wherein a polyelectrolyte “shell” is formed by complexing two different polyelectrolytes together at an interface between two immiscible fluids. Both hydrophilic and hydrophobic materials can be incorporated into the cores and shells of the polyelectrolyte microcapsules.

Abstract: A storage device may include a first care having a first body in which a pet care device is provided and a second case having a second body in which a sterilizer is provided to sterilize the pet care device. A hinge may rotatably connect the first and second cases and allow the storage device to open and close. The sterilizer may emit ultraviolet light.
