  • In response to climate change under a university level, this study has intended to find carbon-neutral campus development measures for Chungbuk National University (CBNU), which is composed of such facilities as education, research, and residential buildings. To reach this goal, we reviewed related literatures to find development measures for carbon neutral campus, employed a survey method asking students to show their preference and suitability toward provided measures, and statistical analyses to find appropriate measures using factor analysis. We have found the following results. First, based on literature review, we have identified several concepts regarding carbon-neutral city and has found the elements of carbon-neutral campus development. Second, we have drawn carbon-neutral campus development measures of CBNU through factor analysis. Finally, based on the characteristics and the present carbon-neutral campus conditions of the CBNU, we presented development measures.

  • Normalized resistance interpretation (NRI) analysis for tetracycline was applied to generate information on the epidemiological cut-off value for Vibrio ichthyoenteri isolated from diseased olive flounder (Paralichthys olivaceus) larvae. Thus, 42 strains of V. ichthyoenteri were used to determine minimum inhibitory concentration (MIC) values of tetracycline using Etest. Also, 11 tetracycline resistance related genes were investigated by PCR method. Most tetracycline-resistant strains harbored both tetB and tetM with a few exceptions. NRI-derived mean and 2 SD above the mean of theoretical normal distributions of susceptible isolates were 0.33 mg/L and 1.66 mg/L, respectively. The epidemiological cut-off value for V. ichthyoenteri from the calculations could be set to S ${\leq}$ 2 mg/L. Of the 42 strains, 15 were classified as non-wild type (NWT), and MIC values of the NWT strains vary regardless of tetB and tetM detection, suggesting that there may be other mechanisms involved in tetracycline resistance in this Vibrio species.

  • The reproductive tracts have an intimate relationship with reproduction because there are bacterial communities that can affect reproductive health. The differences in the bacterial community of periparturient dairy cows were investigated. Vaginal and fecal samples were collected seven days before and after calving, and DNA was extracted to sequence the V3-V4 regions of the 16S rRNA genes. In the postpartum vaginas, operational taxonomic units, Chao1, Shannon, and Simpson were decreased, and phyla Fusobacteria and Bacteroidetes were increased. In summary, bacterial abundance can affect the periparturient biological differences in dairy cows, suggesting a susceptibility to infection within one week after calving.

  • For the first time the concentrations of copper, zinc, lead, cadmium and crome in the tissues from 17 specimens of cetaceans of Korean coast were determined. The measured concentrations of trace elements were considerably lower than the concentrations previously reported in cetaceans. In inter-species, Cd levels were higher in the kidney of Stejneger's beaked whales and the stomach, liver and lung of Risso's dolphin than in the tissues of minke whale and humpback whale.

  • To improve the water solubility of arylsulfonylimidazolidinone (JSH-2282), a potent anti-cancer agent, two urea derivatives, sodium (S)-2-(3-(4-(5-((S)-2-oxo-4-phenylimidazolidin-1-ylsulfonyl)indoline-1-carbonyl)-phenyl)ureido)succinate (2a) and sodium (S)-2-(3-(4-(5-((S)-2-oxo-4-phenylimidazolidin-1-ylsulfonyl)indoline-1-carbonyl)phenyl)ureido)pentanedioate (2b), were synthesized and studied for solubility and anti-cancer activity.
