Remote sensing begins to be applied in Environmental Impact Assessment(EIA), and it can systematically assess land use which is an important factor in EIA. This study is to predict land use change of Ulsan region and to assess impact on land use using the past and the present data of remote sensing. Also we analyzed an impact area influenced by EIA projects through the integration of remote sensing and GIS. This technique will be applied to the screening stage in EIA.

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.

Plant virus coat (CP) gene-mediated protection is one of the best known approaches to protect against virus resistant transgenic plants. Transgenic N. benthamiana plants containing the CP gene of Zucchini green mottle mosaic virus (ZGMMV) were used for the environmental risk assessment of the living modified (LM) plants with plant virus resistance. The most optimal co-infection method of both ZGMMV and CMV (Cucumber mosaic virus) on Non-LM and CP-expressing LM tobacco plants was established and co-infection of CMV and ZGMMV was confirmed by polymerase chain reaction (PCR). To address the effects of LM tobacco plants on the mutation of the virus, in-vitro transcripts of CP and Replicase (Rep) derived from CMV and/or ZGMMV were inoculated onto Non-LM or LM tobacco plants. Mutation frequency of CP and Rep from CMV and ZGMMV was examined through six serial passages in Non-LM and LM tobacco plants. Little actual frequency of mutation was estimated, probably due to the limited number of transgenic plants tested in this study. However, it does not suggest environmental safety of these CP-mediated LM plants. Further study at a larger scale is needed to evaluate the environmental risk associated with the CP-expressing LM plants.

EIA has been developed as a tool for environmental protection into promulgation of the Environment Preservation Act in 1977, with the introduction of EIA concept in the Pollution Control Act amended in 1971. EIA system has been improved with the enlargement of project type, public participation, guiderline improvement, and amendment of Act and presidential decree. Also, this system has been developed to reduce adverse effects affecting environment and human beings for environmentally sound and sustainable development. This study is to analyze contents of Acts and regulations relative to Environmental Impact Assessment from 1971 to recently.

The study is to analyze the contents of Environmental Impact Statement(EIS) and supplementary EIS prepared from 1981 to 1992. The contents are project area, project cost, EIS volume, project term, assessment term, EIS preparation cost, land use plan, and kinds of predictive model concerning air quality, water quality, noise and vibration etc. by project type. Data are collected with EIS analysis checklist and analyzed by $SPSS/PC^+$.

Seven cyanobacteria strains (Anabaena macrospora NIERl0016, Oscillatoria sp. NIER10042, Microcystis aeruginosa NIER10015, M. ichtyoblabe BIER10025, BIER10040, M. novacekii NIER10029, M. wesenbergii NIER10068) were tested with four rRNA - targeted oligonucleotide probes labelled with horseradish peroxidase (HRP) and specific for cyanobacteria. Non- fluorescent detection of hybridization signal was used. The hybridization with artificial mixture of cyanobacteria have shown the possibility to use 2 species-specific probes in duplicate hybridization and detection with different colored substrates.
