The present invention relates to managing defunct processes. The person condition information may include either or both of positional information on the position of the user and postural information on the posture of the user. The sidewall extends from the bottom wall, whereby the inner surfaces of the bottom wall and sidewall define a cavity for holding fluids or loose materials therein. In this electrolytic cell, the possibility of breakage of ion exchange membrane is low, and the anolyte and catholyte have a concentration distribution falling within given range.
