Abstract: A cross-linked nucleoside of the present invention is a compound represented by the formula (I) below. The cross-linked nucleoside of the present invention is usable as a substitute for a phosphorothioate-modified nucleic acid, which has a risk of, for example, accumulation in a specific organ. The cross-linked nucleoside also has excellent industrial productivity.

Abstract: A server device includes a communication unit and a control unit that communicates via the communication unit. The control unit receives, from a plurality of terminal devices, requests to receive a service from one vehicle, each of the requests specifying a provision period and a provision section of the service. Of a plurality of such moving processes that the vehicle is located in the provision section during the provision period of each of one or more services, the control unit sends, to the vehicle, information instructing the vehicle to perform a moving process with a higher total score assigned to a service included in the moving process than a remainder of the moving processes.

Abstract: A controller of an information processing apparatus acquires travel information on a travel by a user from a departure point to a destination, and determines to grant an incentive to the user in a case in which the user is determined to have performed a travel on foot in addition to a travel using a vehicle based on the acquired travel information.

Abstract: A control unit of an information processing device outputs proposal information for proposing to a user of a vehicle that an incentive is given when the user passes, in the vehicle, a point where traffic frequency becomes less than a predetermined threshold value and stops at a predetermined facility, and determines that the incentive is given to the user when determination is made that the user has passed the point in the vehicle and has stopped at the predetermined facility based on movement information of the user.

Abstract: A pre-driving test device includes a control unit that calculates a score of a pre-driving test by outputting request data that requests a user for performing a user operation including, as the pre-driving test, a steering wheel operation, an accelerator operation, a brake operation, or an arbitrary combination of the steering wheel operation, the accelerator operation, and the brake operation, after a vehicle is started and before the vehicle starts moving, acquiring vehicle data recorded in the vehicle while the user operation is being performed, and evaluating the user operation based on the vehicle data acquired, and determines whether to give an incentive to the user by comparing the calculated score with a reference score.
