In recent years,high functionality and complication of stage-controls are increasing.Not only caught and involved,but also falls form high places occur.In this research,taking up safety of stage-control,investigate expressly "lift".In this report,I consider about safety in the show by professional actors.The works in the stage is prefecture to 6 divisions.At the play,it needs not only to prevent critical injury,but also keep the show go on.But it is limited to apply safety equipment in the stage.So the risk by using lift is commissioned to actors,and it is condition that their dangerous failure does not cause a critical injury.In this guarantee,the actors must stop the play before the incident as interlocking.And not to stop the play,they have to increase reliability by the practice.In the practice,it is need to commission safety control step by step within the limit of the actor's ability,so that they can practice safety.

Falling to Stage lift is a critical injury, so that it must be prevented without experience. To avoid an injury of falling, actors must assure safety by active control. Active control is purpose, regulation, and stop control. To keep show go on, it is required for actors to stop performance before falling. And to avoid stop performance, regulate their position not to access the stage lift. Based on these controls, actors can performance, achieving the purpose. To acquire this control, actors have to practice. And the situation of practice and real running is distinguished clearly because safety measures can be applied on one side, and cannot on other. And control of actors includes a dangerous failure comes from human property. It is must to prevent a critical injury comes from their dangerous failure. To that, it is need to disperse energy, and we purpose a device using both of permanent magnet electromagnet as an example. Because friction force from magnet is constant, it can definitely determine force to depend on the human body.

下顎骨関節突起骨折において,コントラアングルドライバーを用いた口内法による観血的整復固定術を施行した1例を報告した。顎顔面領域における骨折のなかでは下顎骨骨折が最も多くみられる。観血的整復固定術を行うには,口外法と口内法があるが,口外法は,顔面神経麻痺や皮膚瘢痕などのリスクがある。一方,口内法は皮膚切開,皮弁挙上の必要がなく,顔面神経麻痺や皮膚瘢痕が生じない。術野の明示は口外法に比較するとやや困難となるが,侵襲を最小限に抑えることが可能であり,今回の症例においては術後の機能障害もなく良好な結果となった。以上のことから,骨折部位が関節突起基底部より低位である症例では,コントラアングルドライバーを用いた口内法による観血的整復固定術は有用な方法であると考えられた。
