Abstract: A discharge device includes a discharge electrode, a counter electrode that faces the discharge electrode in a first direction, and voltage application unit that applies an application voltage between the discharge electrode and the counter electrode. The counter electrode includes a dome-shaped electrode having a recessed inner surface recessed to a side opposite to the discharge electrode in the first direction, and a protruding electrode that protrudes in a second direction intersecting the first direction from an opening edge of an opening of the dome-shaped electrode, the opening being provided at an end opposite to the discharge electrode. The discharge device forms a discharge path having at least partial dielectric breakdown between the discharge electrode and the protruding electrode, when the discharge occurs. The discharge path includes a first dielectric breakdown region generated around the discharge electrode and a second dielectric breakdown region generated around the protruding electrode.

Abstract: A server includes a detection signal reception unit that receives a detection signal related to a detection of an exercise of a user A, an exercise schedule reception unit that acquires an exercise schedule of the user A, and a message request transmission unit that transmits a message request to a UEN of a user N before the exercise schedule. The server further includes a message reception unit that receives a message corresponding to the message request from the UEN of the user N, a determination unit that determines whether or not the user A is exercising according to the exercise schedule based on the exercise schedule and the detection signal, and a mess age transmission unit that provides the user A with the message when the determination unit determines that the user A is exercising according to the exercise schedule.

Abstract: An exercise community formation apparatus includes an exercise-related information acquisition unit configured to acquire exercise-related information for each of a plurality of members belonging to a specific community, an extraction unit configured to extract at least two or more members from the plurality of members based on the exercise-related information for each of the plurality of members, and an output unit configured to output a result of the extraction. The exercise-related information indicates a proficiency level for each of at least one or more exercise subjects of the corresponding member and a time period to which the corresponding member can assign an exercise.
