  • Recently, sporadic cases of human infection by genetic reassortants of H7Nx influenza A viruses have been reported; such viruses have also been continuously isolated from avian species. In this study, A/wild bird/South Korea/sw-anu/2023, a novel reassortant of the H7N1 avian influenza virus, was analyzed using full-genome sequencing and molecular characterization. Phylogenetic analysis showed that A/wild bird/South Korea/sw-anu/2023 belonged to the Eurasian lineage of H7Nx viruses. The polymerase basic (PB)2, PB1, polymerase acidic (PA), and nucleoprotein (NP) genes of these viruses were found to be closely related to those of avian influenza viruses isolated from wild birds, while the hemagglutinin (HA), neuraminidase (NA), matrix (M), and nonstructural (NS) genes were similar to those of avian influenza viruses isolated from domestic ducks. In addition, A/wild bird/South Korea/sw-anu/2023 also had a high binding preference for avian-specific glycans in the solid-phase direct binding assay. These results suggest the presence of a new generation of H7N1 avian influenza viruses in wild birds and highlight the reassortment of avian influenza viruses found along the East Asian-Australasian flyway. Overall, H7Nx viruses circulate worldwide, and mutated H7N1 avian viruses may infect humans, which emphasizes the requirement for continued surveillance of the H7N1 avian influenza virus in wild birds and poultry.

  • Most of the herb residue producing from oriental medical clinics(OMC) and hospitals(OMH) is wasted in Korea. To develop of adsorbent for removing heavy metal from wastewater, the various pre-treatment methods of the herb residue were evaluated by potentiometric titration, Freundlich isotherm adsorption test and the kinetic adsorption test. The herb residue was pre-treated for increasing the adsorption capacity by cleaning with distilled water, 0.1 N HCl and 0.1 N NaOH and by heating at $370^{\circ}C$ for 30 min. It showed a typical weak acid-weak base titration curve and a short pH break like commercial activated carbon during photentiometric titration of pre-treated herb residue. The log-log plots in the Freundlich isotherm test were linear on the herb residue pre-treated with NaOH or HCl like commercial activated carbon. The adsorption capacity(qe) in the Freundlich isotherm test for $Cr^{6+}$ was 1.5 times higher in the pre-treated herb residue with HCl than in activated carbon. On the other hand the herb residue pre-treated with NaOH showed the good adsorption capacities for $Pb^{2+}$, $Cu^{2+}$ and $Cd^{2+}$ even though those adsorption capacities were lower than that of activated carbon. In kinetic test, most of heavy metals removed within the first 10 min of contact and then approached to equilibrium with increasing contact time. The removal rate of heavy metals increased with an increase of the amount of adsorbent. Likewise, the removal rates of heavy metals were higher in the herb residue pre-treated with NaOH than in that pre-treated with HCl. The adsorption preference of herb residues pre-treated with NaOH or HCl was $Pb^{2+}>Cu^{2+}$ or $Cd^{2+}>Cr^{6+}$ in the order. Conclusively, the herb residue can be used as an alternative adsorbent for the removal of heavy metals depending on pr-treatment methods.

  • This research is to set a direction on the recycle of Discarded Automotive tires reforming them into heavy metal adsorbents by developing a particular functional group inducing formation of Chelate complexes with heavy metal ion in the water, on the surface of the used tire conventionally turned into powdered form. For this purpose, through FT-IR, XRD, XRF, SEM, elution test we confirmed and analyzed the property of newly reformed scrapped tires, and functional group. Also, by Kinetics Study we produced an invariable value applying to absorption models. Conclusively the absorption preference of heavy metal is determined to be $Pb^{2+}>Cu^{2+}>Cd^{2+}$, and it reached absorption balance within first 30 minutes, also the absorption reaction time increased from 0.27 to $1.78\sim3.15(g/mg{\cdot}min)$, and showed more than 80% of removal efficiency. This result proved that the efficiency increased by 10 times compared with the conventional powdered Discarded Automotive tires, and the Discarded Automotive tire which implemented the Functional group can exhibit a great efficiency as heavy metal adsorbent.

  • The purpose of this research is to analyze the effect of the traditional color sentiment on the contemporary clothing color by researching the street fashion of 2010 Winter season of Dalian in China, in view of the clothing color of women in their 20-30 years of age, along with traditional Chinese color. This is the 2nd paper following the paper no. 1, focusing on 2010 Summer season, so the research method is same as the paper no. 1. As a result, Black and deep tone PB color most frequently appeared. The vivid and strong tone of R, YR, Y color showed high frequency of clothing colors. This results illustrate that the clothing color choices of Chinese women was affected by Chinese traditional color sentiment rather than the international color trend. Characteristically, in winter season, frequency of R and Y color categories were higher than in summer season, specially in the top and accessories color, those colors showed higher frequency than the other colors. These were the important points in dealing with winter color trend, so that the fashion company and brands should take it an important points when they are planning winter clothing colors. The achromatic colors show the high frequency in both seasons. The bottom color shows high incidence of Black and deep tone of PB color categories as in the previous researches. That means consistent color trend existed in Dalian city, however it does not seem to have its origin from traditional Chinese color preferences. This kinds of regional and seasonal research might contribute to finding the basic informations about the design and marketing strategies to launch into the Chinese fashion market.

  • This study was conducted to grasp distribution of native plants in flower market and uses of native plants in floral decoration. This study was investigated native plants sold in flower market(2017.01-2017.12) and their monthly sales. Also, this study analyzed the use of native plants, frequency of native plants classified by form and color of native plants used for floral decoration in flower magazines 'Fleur' and 'The Flower'. Among 172 species distributed cut-flower, native plants in Korea flower market are only 24 species(14.0%). Number of filler flower(15 species) is more than other forms. Native plants used in 'Fleur' and 'The Flower' were 14 species(10.2%) and 17 species(9.6%), it is meaning that native plants were less used than foreign plants. The number of filler flower was the highest in both magazines, but form flower(299 works) in 'Fleur' and mass flower(571 works) in 'The Flower' are used most frequently. According to color analysis of native plants used for floral decoration, P(purple), PB(navy) and RP(reddish purple) were 57% of the total. It can be increased native plants uses in flower decoration with developing form and mass flower considering color preference.

Two hrs of seasoning time was set, and 23 hrs of drying time was determined in all samples. Finally, T2 product was made by soaking treatments (three times of 1 sec, 8 sec and 1 sec) in $5\%$ (v/v) liquid smoke (Scansmoke PB 2110) after 30 min, 4 hrs and 22 hrs of hot-air drying, respectively. The histamine contents in 3 seasoned-dried products were in a 15.33-26.99 mg/l00g range. The water activities of 3 seasoned-dried products were 0.719-0.735 range, and the pH of T2 was lower than the others. In the comparison of POV and TBA values among products, the TBA values and POV of Tl and T2 were significantly low compared to C, and also the viable cell counts of T2 was relatively lower than those of the others. In the color values, significant changes were not found among products, and in the sensory evaluation for odor, taste and overall acceptance, T2 had relatively higher preference on the whole items.
