I was involved in the work of lecturer of emergency treatment in waterside activities at the university in the prefecture. I was able to spend time learning a lot by being able to be involved in the field where people can be raised through first aid measures in the activities of the waterside. First aid lesson with oxygen is Japan ‘s first attempt. I think that it is wonderful if you can spread various information on the cutting edge from Okinawa to the site of water activities. I think that you can grow natural blues as well as being involved in regional education and school education.
