The fruits of work for four years were summarized in the current fiscal year. And implementation of carbon dioxide processing in a museum and work, and a safe system were built.The tent of the carbon dioxide processing which was being used by research needs to unite with the size of folk culture goods. However, there was a problem which can be used only once with this tent. Then, development of the tent which our research team can reuse is needed.As a result, our research team succeeded in development of the bag for carbon dioxide processing which can manufacture in arbitrary sizes, and is opened and closed with a fastener. Now, this bag is making for Ekika Carbon Dioxide Corporation. In addition, in National Museum of Ethnology, the fastener bag for the biggest carbon dioxide (4m(W)×4m (D)×2.5m (H)) was made in Japan in response to the result of this research. Moreover, we created the process-of-operation manual and the safe manual. As mentioned above, our research team developed the fastener bag set by the size of folk culture goods, and created the work manual and the safe manual. As a result, the carbon dioxide processing by the staff of a museum was attained.
