In addition to design, I wrote the reason why I study many fields on previous article, on this article I write the reason why I study not only medical but nursing. The professor who I respect propound importance of nursing. Development of medical care is very speedy, thanks to this people who can be cured from seriously ill or injury are increasing. Then, after be cured, they are definitely under nursing care, and after nursing care they will be back to their home. Therefore, we need development of nursing care in the quantitative as well as the qualitative sense. For Japan that is facing a aging society problem, nursing care is very important but most engineers and designers don’t realize that. Maybe there is only our lab that realize that thing at the department of engineer of Osaka university, so we have big responsibility as pioneer.
