Abstract: According to an aspect, a bruxism reduction device includes: a force sensor disposed at a mouthpiece; a myoelectric sensor attachable to a human cheek; and a bruxism reduction processor including an electrode attachable to a human outer skin layer at a position corresponding to a muscle that causes a human jaw to open when an electrical signal is applied, the bruxism reduction processor being configured to output the electrical signal from the electrode. The bruxism reduction processor is configured to output the electrical signal when a human is determined to be having bruxism based on an output of the force sensor and an output of the myoelectric sensor synchronized with each other.

Abstract: A reward determination system determines distribution of a reward received from a data user to reward distribution targets in a platform for distribution and utilization of biological data provided by data providers. Each reward distribution target has: development task information obtained by quantifying a workload of a task required for developing the platform into numbers; data provision task information obtained by quantifying a workload of a task required for providing the biological data into numbers; and data processing task information obtained by quantifying a workload of a task required for processing the biological data into numbers. A reliability parameter and a contribution parameter of each task are calculated based on the development task information, the data provision task information, and the data processing task information on each task, and a reward to be allocated is determined for each reward distribution target based on the reliability parameter and the contribution parameter.
