Abstract: A method of operating a memory system, which includes a memory controller and at least one non-volatile memory, includes storing, in the memory system, temperature-dependent performance level information received from a host disposed external to the memory system, setting an operation performance level of the memory system to a first performance level, operating the memory controller and the at least one non-volatile memory device according to the first performance level, detecting an internal temperature of the memory system, and changing the operation performance level of the memory system to a second performance level that is different from the first performance level. The operation performance level is changed by the memory controller of the memory system, and changing the operation performance level is based on the temperature-dependent performance level information and the detected internal temperature.

Abstract: According to an embodiment, a method of providing information on whether an item is available for order includes receiving first information indicating whether items are available for order from a vendor device, receiving second information for requesting to check whether an item is available for order from an orderer device, identifying the item to be checked for order availability on the basis of the second information, determining whether the item is available for order on the basis of the first information and the second information, generating third information indicating whether the item is available for order on the basis of the determination of whether the item is available for order, and transmitting the third information to the orderer device in response to the second information. An embodiment provides a device for providing information on whether an item is available for order.

Abstract: A system for automated delivery worker scheduling. The system may include a memory storing instructions and at least processor configured to execute the instructions to perform operations. The operations may include receiving a forecasted number of sold units for a first period of time; receiving a unit per parcel rate associated with a plurality of camps; determining a number of parcels for the plurality of camps based on the forecasted number of sold units and the respective unit per parcel rate; determining forecasted attendance information for the plurality of camps; determining a number of delivery workers based on the forecasted attendance information and the number of parcels; and assigning a plurality of the parcels to the determined delivery workers.

Abstract: A method for controlling an operation of a compressor and its apparatus can easily control an operation of the compressor without a request for a high-priced operation control apparatus by operating the compressor with controlling the amount of currents flowing into a winding coil of a motor (100) of the compressor according to load capacity of the refrigerator. The apparatus includes a control unit (103) for generating a control signal for selecting a main winding coil (M) of a linear motor (100) of a compressor or an auxiliary winding coil (M2) on the basis of the load capacity of a refrigerator, and a switching unit (101) for selecting the main winding coil (M) of the linear motor (100) or the auxiliary winding coil (M2) on the basis of the control signal. Herein, the main winding coil of the linear motor (100) is divided into a plurality of auxiliary winding coils (M2).
