1. Report:
   * General Report (H. Toki):
     .... Budget and Re-Organization:
     		COE, Top30, Indep. Organization (独立行政法人)
     .... Change of Staffs/Members:
     		Ogata (-> Kyushu U.), Yorita (-> Spring8)
		Yamaguchi (<- Ehime U., YN), Yoshimura (<- Kyoto U., UCN)
     .... Physics: UCN, Spring8

   * Report on the Steering Committee (12/22, 11:00-, A. Hosaka):
     .... Report on Change of Staffs/Members
     .... Activity Reports:
          (30 years anniversary, EMI2001, Hatanaka, Nakano, Sato, Hosaka)
     .... Discussion:
     	  Indep. Organization, Top 30, Reduction of Budget (H14 -> 10 %) 

   * QPAC Report (A. Hosaka):
     The results of QPAC meeting (Hatsuda, Hosaka, Nomachi(chair), 
     Kasagi(Observer)) in September 2001 were reported by A. Hosaka.
     They are also shown in the Annex, and already sent to the contact persons.

   * Report for the future plan (Hatanaka, Sato)
     FFAG, Ring Synchro-Cyclotron, and AC-AG Synchrotron
     have been considered as the next accelerator in RCNP.
     (Ep,I)=(1 GeV, 10 mA) machine will cost around 8-10 Byen.
     If we require Ep=2.7 GeV, cost will be larger by about 30 %.
     To put the next accelerator in the present building or in the present site,
     more area (tennis court area ?) and better shield for walls are necessary.

2. QPAC member change:
     Present members:
	M. Nomachi (chair), A. Hosaka, T. Hatsuda, S.H. Lee, I. Endo, K. Masuda
     Following rules for member selection and experiment selection are proposed.
    	* Regular PAC meeting will be held in September in each year.
	  (Irregular meeting can be held anytime when necessary.)
	* Six QPAC members are in charge of proposal selection for one year,
	  and the QPAC member can be selected again in sequential terms.
	  (任期 1 年、6名、再任を妨げない)
	* QPAC members should include one or two PPAC members,
	  and a few theoretists.
   	* In the first PPAC meeting every year just after the PPAC member 
	  change, two QPAC members from PPAC will be selected.
	* It is preferable to have oral presentations opened to public
	  at the selection of proposals.
	* QPAC can request experimental groups to report the experiment status
	  in the middle of experimental period.

3. Workshops
     RCNP will call Workshops in 2002 as in the last year.
     Deadline is set to 2/25 (Mon.).
     It is also concluded that PPAC members proposes a workshop which is
     dedicated to the discussion on the future plan of RCNP.

4. Discussion of the RCNP future program
    RCNP future plan is discussed, and following direction was suggested
    for the proton machine.

    * The next "Dream Machine" can be opened to public, but we should
      put the main motivation in nuclear physics. RCNP is strong in 
         * Spin-isospin excitation of nuclei, and neutrino interaction
	 * Single and Double Giant Resonances
	 * Pion physics and Chiral Symmetry
	 * Cluster excitation in stable and unstable nuclei
	 * Few-body physics
      and we should keep these strong points also in the next machine.

    * Midium time scale:
      Injector upgrade and Ion source upgrade will cost around 2 Byen,
      and the resolution is improved a lot by these upgrade.
      These upgrades increase the above mentioned strong points of the 
      current Ring Cyclotron.

    * Long time scale:
      Dream machine construction should be considered.
      We expect Ep=(1-3) GeV, and I >= 10 mA. The essential points to 
      keep strong points are Beam Polarization and Good Resolution.

5. Others

    * Next PPAC will be held on March 1 (Fri.), 2002.
