Abstract: A boarding management system according to the present disclosure determines a first time when a moving vehicle is expected to arrive at a boarding location and a second time when a scheduled passenger is expected to arrive at the boarding location. A time lag between the first time and the second time is determined. Depending on the time lag between the first time and the second time, the boarding management device decides whether or not to perform cancellation processing of canceling a boarding reservation, made for the scheduled passenger, of the moving vehicle. The cancellation processing of canceling the boarding reservation is performed in accordance with a decision to perform the cancellation processing.

Abstract: A plunger for a syringe, in which a plunger rod can be prevented by a simple structure from unavoidably falling out of place. The plunger for a syringe includes the plunger rod and a gasket. The gasket is closed at its upper end and has an inner space, and an opening having a diameter smaller than the diameter of the inner space is provided in the lower end of the gasket. The plunger rod has a collar installed at the tip of the plunger rod. When the collar is positioned in the inner space of the gasket, the plunger rod and the gasket are freely movably fitted together without intimate contact between them.
