  • "In summary, the freezing facilitty manufacturing industry has a bright prospects for further development. So followings are recommended: 1) The import restriction policy should be continued to expand the demand for the 10callT manufactured facilities, 2) Training of local people and import of advanced technologies should be encouraged 3) The capacities of the local manufacturing industry should be expanded to meet the: increasing demand for the facilities, 4) Further incentives should be affered to the freezing & cold storage sector for the repla¬cement of the worm-out facilities 5) The marketing channel of marine products should be reorganized into ""cold-chain system"" by providing a legislative supports."

  • Computations are presented for the catechol-$(H_2O)_n$ (n = 1-3) clusters. A variety of conformers are predicted,and their relative energies are compared. Binding energies of the clusters are computed, and detailed analysis is presented on the harmonic frequencies of stretching modes involving the hydrogen bonding in the clusters, comparing with the experimental observations.
