  Note: I will make presentation with speaking in Japanese, but the 
        OHPs I'll use will be written in English.  If you want the 
        English version of above abstract, please contact me (e-mail: 
        utatane@ees.hokudai.ac.jp) without any hesitation.  Of course 
        I'll be willing to take any questions during presentation both 
        in English and in Japanese!
