A physiological information processing apparatus includes a processor and a memory configured to store a computer readable command. The computer readable command is executed by the processor, the physiological information processing apparatus is configured to acquire physiological information data of a subject to which an anesthetic is administered, specify, based on the physiological information data, at least one of an appropriate management time, which is a time during which anesthesia management is appropriately performed on the subject, and an inappropriate management time, which is a time during which the anesthesia management is not appropriately performed, calculate an anesthesia management evaluation index, which is an evaluation index for the anesthesia management, based on the at least one of the inappropriate management time and the appropriate management time and an operation time of the subject, and output the calculated anesthesia management evaluation index.

Physiological information processing apparatus, physiological information processing method and storage medium

The invention provides a data storage device and a method of updating management information, capable of dealing with management information in a highly reliable manner so that information is not easily lost when an error occurs. File management information such as a FAT serving as address management information in a flash memory is stored in a management information area of the memory, a pair of blocks is assigned as blocks for use to store data of the FAT, and writing of updated FAT information is performed by alternately using the two blocks of the block pair such that previous FAT information is retained in one of the two blocks of the block pair, and updated FAT information is written in the other block of the block pair, whereby, even when an error occurs in the middle of the process of writing the updated management information, a process using the retained previous FAT information is possible.

Data storage device, method for updating management information in data storage device, and computer program

A recording medium on which a plurality of programs are collected in a plurality of groups and supervised in this grouped state, wherein when an editing command such as dividing, linking, and erasing the predetermined programs or groups recorded on the recording medium is executed, management data is edited to perform the editing command. The invention provides a solution to meet this request by a recording medium, an editing method and an editing apparatus.
