The purpose of this study is to provide new design techniques for designers to design energy saving balcony in the apartment house using solar energy passively. These design techniques are examined with some samples of foreign buildings used solar energy passively. To classify these design techniques, this study sorts out the energy saving design elements from the preliminary studies. The results of this study show how to apply each design technique to the design of balcony in the apartment house and present a classification table of these techniques. Finally, this study suggests a design solution which can be applied in the design of balcony in existing apartment house.
Long-term Preservation of Bloom-forming Cyanobacteria by Cryopreservation
박해경,Park, Hae-Kyung The Korean Society of Phycology 2006 ALGAE Vol.21 No.1
Long-term preservation of bloom-forming cyanobacteria was evaluated using cryopreservation and freeze-drying of nine strains belonging to four genera and seven species. All test strains, except Aphanizomenon flos-aquae NIER- 10028, showed partial or complete survival following cryopreservation and freeze-drying. Frozen and freeze-dried strains were preserved for more than two years and were revived monthly. Most strains showed higher post-thaw viability after cryopreservation, especially without cryoprotectant compared to freeze-drying. Microcystis aeruginosa NIER-10010, M. viridis NIER-10020, M. ichthyoblabe NIER-10023, M. novacekii NIER-10029 and Oscillatoria sancta NIER-10027 were revived after 2.5 years of cryopreservation. These results suggest that cryopreservation may be an easy and timesaving long-term preservation method for bloom-forming cyanobacteria.
