This study carried out to certify of taxonomic delimitation in A. artemisiaefolia, A. trifida, A. trifida for. integrifolia, and A. psilostachya in the area of literature and experiment. A. psilostachya was not a vestige of naturalized in Korea and A. trifida and A. trifida for. integrifolia didn't have any valuable differences of morphological and molecular biological experiment. I arranged that naturalized species in Ambrosia are A. artemisiaefolia L. and A. trifida L. in Korea.

Purpose: The purpose of this study was to validate the effects that the structured pamphlet and education through tablets regarding the daily life management and disease nursing education program has towards pneumonia patients in compliance, and self-efficacy. Methods: This study used the quasi-experimental study design based upon the nonequivalent control group pretest-posttest design. A total of 100 patients-50 patients who were hospitalized February 2020 as the control group and 50 patients who were hospitalized March 2020 as the experimental group - were used as material for the statistical analysis. These data were analyzed with a significance level of p< .05 using the SPSS WIN 21.0 program. Results: The patients' compliance, and self-efficacy had no significance difference between the two previous scores, meaning homogeneity in the two groups. Through verifying the experimental group who had disease and daily-life managing nursing education will have higher scores in compliance (t= 20.95, p< .001), and self-efficacy (t= 17.24, p< .001) than the control group who had not received those education, were statistically significantly different leading to all hypothesis being supported. Conclusion: For improving pneumonia patients' compliance, the methods should be simple, easy to understand, effective in numerous clinical situations, require constant education and reinforcement, and periodic nursing education program.

Several phages of Bacillus thuringiensis distributed in Korea were isolated. The distribution and morphological characteristics of phages were studied. The results are as follows; 1. The isolated phages were highly specific for Bacillus thuringiensis var. thuringiensis. They were classified as YM series phages and designated as phage YM-1, YM-2 and YM-3 according to their morphological characteristics. 2. Most of these YM series phages were isolated from compost including domestic animal dung and soil under sewage. 3. The YM-1 phage was similar to Bacillus subtilis ${\phi}25$ in morphology. It has 94nm x 86nm head, contractile tail sheath and base plate with four cornered structure. 4. The YM-2 phage was similar to Bacillus subtilis GA-1 phage in morphology. It had 70nm x 56nm head and tail without contractile tail sheath. 5. The YM-3 phage was similar to Bacillus subtilis ${\phi}29$ phage. It had 56nm x 43nm head and tail with distal enlargement.

Five strains of the Genus Rhizobium were isolated from the nodules of five leguminous plants respectively. They were identified according to Bergey's Manual together with the results of Vincent. The flagella of each strains were observed by electron microscope using negative staining with PTA and metal shadowing with chromium. Five host plants and identified Rhizobium strains were as. follows. Pisum sativum.....R. leguminosarum Phaseolus vulgaris.....R. phaseoli Trifolium repens.....R. trifolii Glycine max.....R. japonicum Lupinus grandiflorus.....R. lupini Electron micrographs showed that R. leguminosarum and R. phaseoli had 4 peritrichous flagella, where as R. trifolii had 5 peritrichous flagella. On the other hand, R. japonicum and R. lupini had 1 subpolar flagellum.

The mycelia were directly isolated from eight species of fungal basidiocarps, confirmed to the ectomycorrhiza in the roots from the fields(forestry); Suillus bovinus, Paxillus involutus, Lactarius hysginus, Russula fragilis, Lepista nuda, Lyophyllum shimeji, Tricholoma matsutake, and Russula integra. The mycelia were pure-cultured with several transferring in various agars, and inoculated to the roots of pine(Pinus densiflora) seedling by in vitro method. After ten months growth under artificially aseptic conditions, all pine seedlings inoculated were stimulated at the growth-height, whereas those not inoculated were nearly dead. Also, the ramifications of ectomycorrhizal pine roots formed in the synthetic in vitro systems and were various according to the different mycelia. Synthesis of ectomycorrhiza were clearly confirmed in ten months growth, but not distinguished at this moment. It was clearly proved that the mycelia isolated caused the ectomycorrhizae in the roots of pine seedlings.

Differential display of reverse transcription(DDRT)-PCR was conducted to have a profile of the differentially expressed genes during the formation of fruiting body of Lentinus edodes. The lines of L. edodes(ImHyup-1) employed were cultivated in the artificial blocks of sawdust, and the fruiting body was induced from the mycelia or the mass protruded from the brown surface of the sawdust blocks. RNAs were prepared from the four different developmental stages; mycelial, primordial, and stipes and pileus of fruiting body. The fragments of cDNA were synthesized from the combinations of the arbitrary primers and 3' one anchored Oligo-dT primer. Twelve combinations using the primers have been tested, and among them nineteen bands were identified as differentially expressed. Those genes were further analyzed by DNA sequencing and followed by homology search. Characterization of one clone was conducted as a preliminary data and more are under investigation.
