  • 던지기 동작은 wind-up, early and late cooking, acceleration, deceleration, follow-through 6단계로 나눌 수 있다. 야구에서 과사용 증후군에 의한 손상은 대부분 던지기 동작에서 발생된다. 잘못된 던지기 동작은 상지 손상의 원인이 된다 본 종설의 목적은 동작 분석을 통하여 던지기 동작에 수반되는 각 관절의 생역학 및 병적 역학을 파악함에 있다

  • Asymmetrical posture during static stance has been identified as a common problem in persons with hemiplegia. This study examined the effect of a purposeful exercise training program on symmetrical weight bearing in three adult persons with hemiplegia. Multiple baseline design was used. The intervention program, including ball throwing and catching, rolling ball catching and throwing, and Swiss ball pulling and stopping was introduced for 15 minutes each day during each intervention phase. Quantitative measurement of the weight distribution was taken with the Limloader. Visual inspection and mean of data revealed a significant improvement in symmetrical weight distribution. This result suggests that a purposeful exercise training program can be effective in helping persons with hemiplegia achieve symmetric stances.

  • In this paper, we describe the structural reinforcement approach of the throwing-type firefighter assistance robot which can be thrown into a fire site to monitor inside the place and search trapped people while ensuring a firefighter's safety. The reinforcement design is focused on high strength with low weight for the robot. The in-depth structural analysis of the platform is carried out to track down the weakest part, especially with the 1.8m height of drop test. The analysis is verified by comparing with the 1.8m height of the drop test of the throwing-type firefighter assistance robot. The optimal approach for improving the strength of the weakest part aims at topological equivalent and equivalently stress distributed shape.
