Abstract: According to an embodiment of the present technology, a storage device includes a non-volatile memory device including a first memory block area and a second memory block area, and a storage controller configured to control the non-volatile memory device, determine a target erase count based on a generated assignment request among a first assignment request and a second assignment request, and assign a target memory block corresponding to the target erase count, as a memory block corresponding to the generated assignment request, to a shared block pool. The first assignment request corresponds to a memory block of a first type in the first memory block area, the second assignment request corresponds to a memory block of a second type in the first memory block area, and the target memory block is included in the first memory block area.

Abstract: The present invention relates to a hydrogel composition comprising a chloroplast, a chloroplast transit peptide, alginate, and a pancreatic cell, and can supply oxygen to a cell or a tissue and control carbon dioxide and exhibits excellent preventive or therapeutic effects on diseases such as diabetes, etc., and thus may be utilized in the tissue engineering field such as organ transplant.

Abstract: A semiconductor device includes a substrate including a first region and a second region, a buried gate structure located on a first recess in the first region of the substrate, and a recess gate structure located on a second recess in the second region of the substrate, wherein the buried gate structure is buried in the substrate, an upper portion of the recess gate structure is not buried in the substrate, and a first work function adjustment layer in the buried gate structure may include a material identical to a material included in a second work function layer of the recess gate structure.

Abstract: A system and a method of determining the location of parked cars in a parking area includes a vehicle-mountable transceiver and a plurality of transceivers disposed throughout the parking area. Each vehicle-mountable transceiver has or is assigned an identification code by which communications between the vehicle-mountable transceiver and the transceivers may be interpreted as a vehicle location. A portable device may also be used, where the portable device may communicate with the vehicle-mountable transceiver and with the transceivers. A server maintains a database having the vehicle identification codes, and the locations of the vehicles and provides vehicle location information to the driver, either in printed form, audible form, or in the form of information transmitted to the portable device.
