The processor is configured to correct the correction target first data, using data in a predetermined range of the time-series data. The processor is configured to generate ground data indicating correction grounds for the corrected correction target first data, based on the data in the predetermined range, and add the ground data to the corrected correction target first data.

Abstract: An information processing system includes a first service server that provides a first service. The system includes a communication circuitry and a control circuitry. The communication circuitry communicates with a user terminal of a user not having a first account of the first service and with a second service server that provides a second service different from the first service. The control circuitry sends a purchase request screen to the user terminal when a purchase request for a commodity or service has been received from the user terminal, inquires of the second service server whether or not the user has a second account associated with predetermined identification information of the user when the identification information is entered on the purchase request screen, and sends display information for registering the first account and performing linking processing of the first account and the second account when the user has the associated account.

Abstract: A system including a first server that provides a first service is provided and includes communication and control circuitry. The communication circuitry communicates with a terminal of a user having a first account of the first service and with a second server that provides a second service. The control circuitry sends a request screen to the terminal when a request for a commodity or service has been received from the terminal in a non-logged-in state with the first account, inquires of the second server or a server associated with the second server whether the user has a second account associated with identification information of the user when the identification information is entered on the request screen, and sends, to the terminal, display information for logging in with the first account and performing linking processing of the first account and the second account when the user has the associated account.

Abstract: The base oil for the refrigerating machine oil used with a carbon dioxide refrigerant of the invention is characterized by comprising a complete ester of a fatty acid in which the proportion of C14-C22 branched fatty acid is 40-100% by mole and a polyhydric alcohol. The refrigerating machine oil used with a carbon dioxide refrigerant according to the invention is characterized by comprising the base oil for the refrigerating machine oil used with a carbon dioxide refrigerant according to the invention. The base oil for the refrigerating machine oil used with a carbon dioxide refrigerant and the refrigerating machine oil used with a carbon dioxide refrigerant according to the invention, when used together with a carbon dioxide refrigerant, exhibit excellent stability and electrical insulating properties, and have suitable compatibility with refrigerants while allowing adequate lubricity to be exhibited without increasing the viscosity of the base oil.

Abstract: The invention provides a process for producing a monoglyceride-containing composition by reacting glycerin with at least one kind of acyl-containing compound selected from fatty acid and glycerin ester, the reaction being conducted with a catalyst containing at least one metal selected from iron, cobalt and manganese in an amount of 0.1 to 60 ppm in terms of metal (weight ratio to the total weight of glycerin and the acyl-containing compound), as well as a process for producing a monoglyceride-containing composition by reacting glycerin with at least one kind of acyl-containing compound selected from fatty acid and glycerin ester, including a step of maintaining the amount of water at 500 to 5000 ppm in the reaction system after the degree of conversion in the reaction of glycerin with fatty acid reaches 90% or more based on the fatty acid, or during the ester exchange reaction of glycerin with glycerin ester.
