The present study was conducted to investigate the prevalence, biochemical properties and plasmid profiles of Salmonella organisms isolated from wild birds in Daegu area during the period from May, 1999 to August, 2000. Twenty strains of Salmonella were identified from 192 samples of heron feces and 86 samples of pigeon feces. Among Salmonella isolates, S. montevideo were the most frequent serotype (16 strains), 3 strains of them were S. typhimurium and the other one was untypable. The biochemical properties of 20 strains of Salmonella isolated were in accordance with the traditional characteristics of Salmonella spp. in the majority of biochemical test such as IMViC, carbohydrate fermentation and amino acid decarboxylation. The majority of isolates were highly susceptible to amikacin, ampicillin, amoxicillin, carbenicillin, cephalothin, ciprofloxacine, chloramphenicol, enrofloxacin, furazolidone, gentamicin, kanamycin, nalidixic acid, polymixin B and sulfamethoxazole, while they were moderately susceptible to streptomycin and tetracyclin. However, the majority of them were highly resistant to nitrofurantoin. In plasmid profile, 21.1 kilobase (Kb), 20 Kb and 13.2 Kb fractions were common to three S. tvphimurium and one untypable strains, and no fraction was shown in all strains of S. montevideo.

This study investigated the effects of changes to the pulsation factor of pulsed direct currents on wound healing. Patients with a pressure ulcer at a care hospital for the elderly were randomly divided into three groups: Group 1 involved the application of 100㎲ in pulse duration, 10 ㎳ in pulse period, 100 pps in a pulsation factor, 15 ㎃ in pulse amplitude, and polarity red+ by using pulsed direct currents; Group 2 involved a change of pulse period to 8 ms; and Group 3 received general wound management. Although there were no statistically significant differences in the changing stages of pressure ulcers among the groups, all the groups dropped in numerical stages. In the two groups to which pulsed direct currents were applied, there was a statistically significant reduction in the stages of pressure ulcers from the initial assessment to the 12-week assessment (p<.05). Even though there were no statistically significant differences in changes to the area of pressure ulcers among the groups, a statistically significant decrease was found in pulsed direct current group 2 whose pulse period was shortened (p<.05). There was no difference in the healing rate of pressure ulcers among the groups, but it made a numerical increase in pulsed direct current group 1 and group 2 and a numerical decrease in group 3. There were no significant differences in the characteristics of those who had a full recovery among the groups. Those findings indicate that pulsed direct currents have positive effects on the wound healing of patients with a pressure ulcer and that a treatment with pulsed direct currents whose pulsation factor is raised by reducing the pulse duration is especially effective.

The study aims to define the Korean Wave as global attention to Korea’s unique culture and consider the specificity of traditional Korean fashion images in Korean Wave content. The research method of this study is a case study through literature research. In order to collect Korean Wave content on YouTube, 24 channels with the highest number of views were selected from among content uploaded from 2018 to the present through keyword search, and up to two channels with high views showing traditional Korean fashion images. As a result of selecting the analysis target, 41 Korean Wave videos and 368 costumes were selected and analyzed based on fashion style elements, including item, color, detail, motif, styling, silhouette, and accessory. As a result of the study, music, broadcast, fashion, and other content were found in the Korean Wave content fields in which Korean fashion style appeared, and the characteristics of each field were derived. Music content was characterized by fashion style excluding stereotypes about traditional Korean costume, broadcast and fashion content was characterized by fashion style inherited from traditional costume, and other content was characterized by symbolic fashion style of traditional culture. This study is meaningful in revealing the formative characteristics of traditional Korean design elements recently shared online through the study of Korean traditional fashion images in Korean Wave content.

<P>The expression of different toll -like receptors (TLRs) on tumor cells has been associated with disease aggressiveness, treatment resistance, and poor prognosis. The phosphatidylinositol 3-kinase (PI3K)/AKT pathway is considered critical for cancer cell survival and proliferation. Thus, we investigated the effect of TLR-stimulated PI3K activation on the epithelial-to-mesenchymal transition (EMT) of primary (Caov-3) and metastatic (SK-OV-3) epithelial ovarian cancer cell lines in this study. TLR engagement with various ligands promoted the expression of class IA PI3K (p110 alpha, p110 beta and p110 delta) and increased the expression of mesenchymal markers (N-cadherin, Slug, Vimentin, Snail, alpha-SMA, and TCF) in SK-OV-3 cells. The migratory activity and secretion of EMT-related cytokines of SK-OV-3 were significantly higher compared to those of Caov-3 after activation with TLR agonist. Although the invasive capacity and production of EMT-related cytokines of LPS-stimulated SK-OV-3 cells were significantly suppressed by all pharmacological inhibitors of the p110 isoform, the Syk/Src-dependent p1101 beta isoform prominently attenuated migration activity. In contrast, the production of IL-10 and galectin-1 was mainly affected by the p110 delta isoform. Gene silencing of TLR4 and galectin-1 with siRNA decreased the expression of matrix metalloproteinase-2 (MMP2) and MMP9 and reduced mesenchymal markers in LPS-treated SK-OV-3 cells. This study demonstrated that TLR-mediated PI3K activation modulated the invasion and metastasis of ovarian cancer through the production of galectin-1, suggesting that inhibition of the p110 isoform is a promising therapeutic approach against metastatic ovarian cancer.</P>
