Abstract: Embodiments of the present disclosure relate to a system and an operating method of the system. Based on some embodiments of the disclosed technology, the system may include a random access memory structured to include memory cells to store data, a cache memory configured to cache at least part of the data, and a processor in communication with the random access memory and the cache memory to access at least part of the data from the random access memory or cache memory. The system may determine a cache hit ratio for the cache memory, and may set an operating frequency of the random access memory based on the cache hit ratio.

Abstract: Disclosed is a bulk block for manufacturing a prosthesis having high aesthetics and processability required for one-day dental prosthetic materials, which is a dental composite bulk block comprising a glass ceramic matrix and a polymer, wherein the glass ceramic matrix consists of an amorphous glass matrix and a crystalline phase dispersed in the glass matrix, the crystalline phase comprises as a main crystalline phase at least one selected from a leucite crystalline phase and a lithium disilicate crystalline phase, and has an average particle diameter of 0.01-1.0 ?m, and the polymer is included in an amount of 20-40 wt % with respect to the weight of the total bulk block. The bulk block has the advantages of improved mechanical properties, being capable of preventing microleakage, exhibiting excellent aesthetics, and enabling machining.

Abstract: A method performed by an apparatus for providing nursing service is provided. The method includes: receiving result information about nursing service provided to a patient from a first medical care provider terminal, extracting rule information that is pre-set with respect to the nursing service, determining whether the result information corresponds to the rule information, and transmitting the result information to a second medical care provider terminal if the result information corresponds to the rule information.

Abstract: A method manages a care service by a terminal apparatus of a caregiver. The method includes recognizing a smart card of a patient, receiving encrypted data including encrypted time information from the smart card, the encrypted time information being generated at the smart card by encrypting time information corresponding to a point in time when the terminal apparatus recognizes the smart card, and transmitting the encrypted data to a management server. The encrypted data is generated by the smart card using an encryption key and decrypted by the management server using a decryption key corresponding to the encryption key. A time corresponding to time information acquired from the decrypted data is stored in the management server as a care service providing time.

Abstract: A method and apparatus for managing call information is provided. The method includes: receiving reception notification data from a server that indicates call information is received, receiving the call information from the server according to the reception notification data in response to an input of a manager and displaying the call information and an initial process state of the call information on a screen of the display.

Abstract: A method protects care information in a care provider terminal. The method includes detecting if there is a network disconnection between the care provider terminal and an authorized access point (AP), operating the care provider terminal in an offline mode until a first predetermined time is over after the network disconnection is detected, activating an alarm operation when the first predetermined time is over, and deleting the care information when a second predetermined time is over after the alarm operation is activated. The method may further include determining whether or not the care provider terminal is connected to an unauthorized AP while counting the first predetermined time or the second predetermined time, and deleting the care information if it is determined that the care provider terminal is connected to the unauthorized AP.
