In this study, we evaluated the shock mitigation armor at the time of falling backwards, and as a result we found that armor protecting head and neck is the best result. Moreover, even if the shock was relieved, it was found that the armor where the head touches the ground is not suitable for a rearward fall

This paper describes the relation between infantile crying and thrombus generation near intravenous indwelling needle in veins. In this study, it is assumed that the difference of pressure or flow rate between normal and infantile crying causes thrombus formation. First of all, the blood pressure of infant are measured, and the difference of blood pressure between normal status and infantile crying. It was found that the blood pressure increases according to the infantile crying, and the difference of blood is approximately 20 mmHg. To investigate the flow field of the flow, CFD analysis around the indwelling needle of drip injection (catheter) in the infantile vein was done. The results show that the increasing flow rate or velocity make the accumulation of particle around the inlet of the catheter.
