Subject: Request literatures
This is Yusuke Yamana in Wakayama, Japan.
Presently I faced with slight difficulties. Please help me. I want several literatures, that I cannot obtain in Japan in any way. I expect that someone have these literatures. If you have, can you send me copy of following documents?
