  • In order to investigate bacterial sanitary condition of fish and shellfish, we examined the normal flora in the 25 species of commercial fish and shellfish, and also proportional change of normal flora by storage period and temperature. Isolated 334 wereisolated in the normal fish and shellfish and predominant genera were Pseudomonas (25.2%), Staphylococcus(10%), Acinetobacter (7.2%), Vibrio (6.9%), Micrococcus (5.4%), Aeromonas (5.2%), and Enterobacter (5.2%). In accordance with storage period and temperature, Pseudomonas grew on high ratio at 1$0^{\circ}C$ steadily, but Proteus had increased proportionally at 2$0^{\circ}C$ and 3$0^{\circ}C$. Additionally, Yeast, and Micrococcus had decreased by period.

  • The flora and vegetation of the alpine grassland at Dalmoon on Mt. Paektu were investigated on July 24, 1997 by 1 m ${\times}$ 1 m quadrat method. The flora of the vascular plants investigated on this alpine grassland was 36 taxa belonging to 17 families, 35 genera, 29 species, 3 subspecies, 4 varieties. Te leading families were Compositae (7 taxa) and Gramineae (4 species), and the forb was more than the grass. Four dwarf shrubs which were Salix metaformosa, Dryas octopetala var. asiatica, Rhododendron aureum and Vaccinium vitis-idaea were found at the studied sites. This alpine grassland was composed of 17 communities, Astragalus uliginosus, Sanguisorba sitchensis, Deschampsia caespitosa were dominated over 18, 5 and 4 quadrats, respectively.

  • Purpose: A longitudinal study was conducted to explore flora colonization and oral glucose high-risk newborns during the first 7 days after birth. Methods: Oral secretions of hospitalized newborns were obtained for microbial cultures and glucose test at days 1-7 after birth. Results: Among the total 112 newborns, 40% were girls and 73% were premature. Mean gestational age was $34.4{\pm}3.2$ weeks and weight was $2,266{\pm}697.5$ grams. The most common flora included Streptococcus (28.2%), Methicillin-resistant Staphylococcus aureus (MRSA, 10.9%), Staphylococcus (6.0%) and Coagulase-Negative Staphylococcus (CNS, 4.0%). The average oral glucose level was $29.2{\pm}23.0mg/dL{\sim}58.2{\pm}39.5mg/dL$. Newborns with higher oral glucose than serum (crude odds ratio [ORc] =1.75; 95% confidence interval [CI] =1.03-2.97), phototherapy (ORc=3.30; 95% CI=2.29-4.76) and prone position (ORc= 2.04; 95% CI=1.13-3.69) were more likely to be colonized. Having oral tubes (ORc=0.42; 95% CI=0.29-0.59), parental nutrition (ORc=0.21; 95% CI=0.13-0.32) and antibiotics (ORc=0.51; 95% CI=0.36-0.73) had protective effects. For oral glucose statistical significances existed on time effect among newborns with Streptococcus (F=9.78, p=.024), MRSA (F=7.60, p=.037) or CNS (F=11.15, p=.019) and interaction between time and colonization among newborns with all of four flora (F=2.73, p=.029) or colonization with only Staphylococcus (F=2.91, p=.034). Conclusion: High-risk newborns develop flora colonization at an early period of life. Their clinical features were associated with types and time of oral flora colonization. They need close monitoring and multifaceted intervention to improve oral environment and infection control.

  • Benthic marine algal community of a sea bank at Joomoonjin, in the eastern coast of Korea, was investigated monthly in view of floristic composition and seasonal periodicity during from August, 1989 to July 1990. Total number of benthic alga identified were 70 taxa, which composed of 7 species of Chlorophyta, 21 species of Phaeophyta and 42 species of Rhodophyta. The dominant species were Sargassum horneri, Underia pinnatifida, Laminaria japonica and Pachymeniopsis sp.. Vegetation, from the point of phygiognomy, was a mosaic type by these dominant species. The flora was compared with similarity index using S${\phi}$rensen coefficient and grouped by a cluster analysis. As a result, the algal community of this area could be divided into two clusters at similarity level 45% : Flora of water temperature-ascending period(January-July) and flora of water temperature-descending period(August-December). And also, the former flora was subdivided into two clusters at point of the $14^{\circ}C$ sea water temperature : winter flora(January-April) and spring-summer flora(May-July). The flora of this area was characterized as a mixed flora of cold and temperature zone by Cheney's index.

  • The marine benthic algae of Gojeong-Ri was investigated in a floristic aspect. As a result, 34 species, 7 blue-green, 14 red, 6 brown and 7 green algae were identified as a summer flora from the area. Among them, Sirocoleum kurzii (blue-green alga), Ralfsia clavata (brown alga), Pseudulvella consociata and Cladophora speciosa (green algae) were known as new records to Korea.

  • We investigated the bryophyte flora of Taebaeksan Mountain National Park in Korea by conducting a total of ten field surveys from April of 2017 to October of 2019 at various mountainous sites in the park. During the surveys, we recorded 274 taxa belonging to 68 families, 143 genera, 267 species, 3 subspecies, and 4 varieties. Among these, 92 species were reported as new to the flora of the Taebaeksan Mountains. A checklist based on a study of 990 specimens is provided as well. The most remarkable species were Sphagnum capillifolium (Ehrh.) Hedw, Sphagnum girgensohnii Russow, Buxbaumia punctata P.-C. Chen et X.-J. Li, Pleuroziopsis ruthenica (Weinm.) Kindb., Ptilium crista-castrensis (Hedw.) De Not., and Douinia plicata (Lindb.) Konstant. et Vilnet.

  • This experiment was carried out to investigate on the flora and cardinal wild mushroom in Tricholoma matsutake producing sites at the Namweon area. The results were as follows: Flora of Tricholoma matsutake producing sites were prevailed over at tree layer (Pinus densiflora S. et. Z.), shrub layer (Rhododendora mucronulatum TURCZ., Quercus serrata THUNB.) and herb layer (Carex humilis LEYSS.). Piedominant wild mushrooms were Boletaceae (Suillusplacidus Bon.) and Ramariaceae (Ramaria botrytis Fr.)

  • The flora of the Hallyo-Haesang National Park were surveyed from May to September, 1998. The flora of this park were listed as 117 families, 296 genus, 373 species, 53 varieties, 7 forms and 3 hybrid in the Namhae, 73 families, 129 genus, 153 species, 16 varieties and 2 forms in Karasan(Mountain), 97 families, 280 genus, 475 species, 53 varieties, 5 forms and 1 hybrid in the Tongyong. Construction of road, recreational facilities and ornamental farms were considered as the major causes of destruction of vegetation conservational measures must be applied urgently to conserve the distinct vegetation and flora of this areas.
