  • The author was carried out bacteriological identification, and in order to evaluate the sensitivity of the different chemotherapeutic agents including chloramphenicol to Vibrio parahaemolyticus isolated from the stool of the patient's diarrhea. The results obtained were as follows: 1) Biochemical properties of Vibrio parahaemolyticus strains isolated from patients with diarrheal food poisoning was showed Table 1. 2) The sensitivity pattern of the isolated strains of Vibrio parahaemolyticus were sensitive to chloramphenicol, sulfonamide, kanamycin and colistin. But tetracycline, penicillin and leucomycin were resistant.

  • Lactobacilli proliferating in fermented sausages of the specific ripening conditions were isolated from fermented sausages, manufactured in the absence of an added starter, during ripening under controlled temperature-humidity conditions. Based on morphological, physiological and bio- chemical characteristics and carbohydrate fermentation of isolated strains, three strains of isolates were identified as Lactobacillus curvatus, two strains as Lactobacillus sake. Optimal temperature and pH for growth of isolated strains were 30$\circ$C and pH 6.0~7.0, respectively. These strains were salt tolerant, multiplying in the presense of 6~8% NaCl.

  • Three tricyclic pyridone alkaloids, (-)-4,6'-anhydrooxysporidinone (1), (-)-6-deoxyoxysporidinoCne (2), and (-)-sambutoxin (3) were isolated from cultures of Fusarium lateritium SSF2 derived from the fruits of Cornus officinalis. Chemical structures of the isolated compounds were determined by spectroscopic method and comparisons with reported data values. The compounds 1-3 were isolated for the first time from this fungal strain.

  • Recent molecular and polyphasic taxonomic approaches toward bacterial systematics have played a significant role in revolutionizing our insight in the taxonomy of bacterial organisms. This advance has also contributed greatly to delineation of new taxa from bacterial organisms isolated from a variety of natural sources of Korea. Recently, many bacterial organisms have isolated from soil, seawater, foods, wastewaters and humans of Korea and have been subjected to polyphasic taxonomic study. From the results of this study, some isolates have been found to be members of new genera and new species.

  • K-means iteration method is generally used for creating the templates in speaker-independent isolated-word recognition system. In this paper the initialization method of initial centers is proposed. The concepts are sorting and trace segmentation. All the tokens are sorted and segmented by trace segmentation so that initial centers are decided. The performance of this method is evaluated by isolated-word recognition of Korean digits. The highest recognition rate is 97.6%.

  • Microbiological culture was conducted in the meat surface of cattles and pigs that was slaughtered in the Chung -Ju area and the result are as follows : 1. The number of bacteria in antemortem meat surface was higher ten times in March and ten to one thousand times in June to August compared with postmortem meat surface. 2. Microbes isolated in the meat surface, at the time of slaughter, was Stahylococcus spp., E. coli, Fungus and Streptococcus spp. 3. Bacteria was isolated in every parts of meat surface regardless to their location and many Fungus was isolated during summer.

  • this work was designed to study the species belonging to Family Rhodospirillaceae in Korea. The species of Rhodopseudomonas palustris and R. gelatinosa were isolated and identified. The utilization of various substrates such as malate, succinate, citrate, pyruvate, propionate and acetate were tested with isolated KS 007 and KS o16. Though there were some differences according to nitrogen source in media it was thought that he intermediates of TCA cycle were comparatively good substrates, Also it was confirmed that isolated strains have the ability of nitrogen fixation.

  • One new and three known coumarins were isolated from the $CHCl_3$ soluble fraction of Angelica dahurica stem. On the basis of spectral data, the structures of the isolated compounds were determined to be scopoletin, angelol I, angelol H and 6-[(1S), 2(R)-2, 3-dihydroxy-1-methoxy-3-methylbutyl]-7-methoxycoumarin; the latter being isolated for the first time from a plant source.

  • The model of an isolated organ system has been developed to simulate the kinetic behavior of drug levels in an acting organ or site. The model is developed from basic considerations of drug distribution with hemodynamical and pharmacokinetical meanings. Model: It is considered a situation in which non-metabolic drug substance is injected into the arterial inflow of an isolated organ at constant rate. The volume of distribution and the concentration of drug in the venous outflow can be mathematically expressed as a function of time.
