Purpose: This study was aimed to identify the influencing factors on the COVID-19 infection prevention behavior of adults residing in Gyeongsangnam-do by examining relationships between anxiety, health belief and COVID-19 infection prevention behavior. Methods: The participants of this study were recruited from a website, and the total number of participants was 186. The self-report questionnaires were distributed during July 2020. Results: Multiple regression analysis revealed the significant factors affecting the COVID-19 infection prevention behavior of adult residing in Gyeongsangnam-do were perceived barriers(��=-3.68, p<.001), perceived benefits(��=3.39, p=.001), perceived susceptibility(��=2.83, p=.005), sex(��=2.59, p=.010). The total explanatory power of the study variables for COVID-19 infection prevention behavior was 35.0%(F=17.61, p<.001). Conclusions: Based on these findings, in order to promote COVID-19 infection prevention behavior, there is needed to reduce obstacles for carrying out infection prevention behaviors, and develop multi-faceted promotional strategies for infection prevention behaviors.

Acute osteomyelitis caused by Klebsiella pneumoniae is rare in the oral and maxillofacial region. Klebsiella pneumoniae is a Gram-negative bacillus and the normal flora of the human body, but it can cause pneumonia, urinary tract infection, meningitis, and osteomyelitis in patient with compromised immune systems. These infections are mainly caused by nosocomial infection. Microbacterial osteomyelitis was developed by clinical cause such as tooth extraction, fracture, and surgical history, which requires long-term antibiotic administration and surgical treatment. This report describes that a 56-year-old male patient with acute osteomyelitis caused by Klebsiella pneumoniae infection after implant placement was treated with intravenous administration of ertapenem without open surgery treatment. Through this case, we report that antibiotic susceptibility test is essential for the treatment of acute osteomyelitis caused by a bacterial infection resistant to empirical antibiotics, and early administration of appropriate antibiotics can reduce the possibility of extensive bone destruction or additional open surgery.

This survey was performed to investigate the seroprevalence of antibodies to Brucella canis in dogs from public animal shelters and breeding kennels in Incheon. A total of 402 dogs selected randomly were tested serologically by using immunochromatographic antibody test kit. None of 289 dogs in public animal shelters were sero-positive and 10 (8.9%) of 113 dogs in breeding kennels were sero-positive. 5 (4.4%) strains of Brucella canis were isolated from 10 sero-positive dogs' blood. Antimicrobial susceptibility test was carried out by Disk diffusion method. They were susceptible to tetracyclines, quinolones, aminoglycosides and combination amoxicillin with clavulanic acid.

Objectives: A number of studies have shown that chronic hepatitis B virus infection is implicated in susceptibility to pancreatic cancer. However, the results are still controversial. This meta-analysis aimed to quantitatively assess the relationship between chronic hepatitis B virus infection and incidence of pancreatic cancer of cohort and case-control studies. Methods: A literature search was performed for entries from 1990 to 2012 using PUBMED and EMBASE. Studies were included if they reported odds ratios (ORs) and corresponding 95% CIs of pancreatic cancer with respect to the infection of hepatitis B virus. Results: Eight studies met the inclusion criteria, which included five case-control studies and three cohort studies. Compared with individuals who have not infection of hepatitis B virus, the pooled OR of pancreatic cancer was 1.403 (95%CI: 1.139-1.729, P=0.001) for patients with hepatitis B virus infection. Sub-group analysis by study design showed that the summary OR was 1.43 (95%CI: 1.06-1.94, P=0.021) when pooling case-control studies and 1.31 (95%CI: 1.00-1.72, P=0.05) when pooling cohort studies. Conclusion: Findings from this meta-analysis suggest that chronic hepatitis B virus infection may increase the risk of pancreatic cancer. This relationship needs to be confirmed by further follow-up studies.

We investigated the contamination of animal hospital floor, beauty table, computer keyboard, exam table, operation table and forcep handle by isolations of aerobic bacteria in small animal hospitals in Gwangju. The total number of aerobic bacteria was 52 isolates and Staphylococcus spp. (38 isolates) were the predominant isolates (69.71 %) of them. The prevalent contaminated areas were floor (17 isolates), beauty table (13 isolates) and computer keyboard (9 isolates). The detection of methicillin-resistant (mecA) gene, determined by PCR, showed that 3 of the 17 coagulase-negative Staphylococcus spp. (CNS) isolates possessed the mecA gene. For evaluating the antibiotic susceptibility patterns of the isolates, disk diffusion method was used. The majority of isolates showed high susceptibility to amoxicillin (92.1 %), ceftiofur (84.2%) and polymixin B (73.7%). Also they showed the high resistant to ampicilline (66.7%), penicillin (65%) and kanamycin (56.5%). These results suggest extensive contamination of aerobic bacteria in animal hospital environment.

Effect of grape seed extract (GSE) against Candida albicans was examined under in-vitro and in-vivo conditions. The GSE was extracted in ethanol. In-vitro results from an agar diffusion susceptibility assay showed the GSE inhibited C. albicans growth. This anticandidal effect was at dose-dependency. In experiments with animals, mice that received the GSE (0.5 mg per mice), intravenously (i.v.), before i.v.-infection wish viable C. albicans yeast cells survived longer than diluent (buffer)-received control mice. In contrast, when GSE was given to mice after the mice were infected with the yeast cells, these mice showed a similar survival rate as compared to control mice that received no treatment with the GSE. Taken together, these data indicate that GSE has prophylactic effect but not therapeutic effect against disseminated candidiasis.

Test plants with 10 days old primary leaves were indouclated by shaking infected seedlings with sporulating colonies over them in an inoculation room under the conditions of 20$\pm$1 $^{\circ}C$ with constant illumination of 2.500 lux and 100% realtive humidity. A seeding reaction of 4 days after inoculation appreared in the trisomic types as opposed to Tri-5B line had been symtoms of a fungus 3 days after inoculation. The infection types of 8 days after inoculation were recognized with higher susceptibility to each trisomics in A genomie than B-genome. Tri-2A line showed less condium and there appeared symptoms of a conditions of mottle and formed papilla, and haustorium was not formed. However, Tri-5B line had much condium one overall leaves and showed a symtom like necrosis compared with normal plant. Moreover, Tri-5B line showed high sensitivity and high germination number of condium. These results inferred that resistant gene located on 2A chromosome and susceptibility gene is located on the chromosome 5B.

The purpose of study was to confirm theory about the effectiveness of routine mental care on the reduction of catheter-associated urinary tract infection. The study was carried out at a university hospital from September 1,1987 to April 17, 1989 : 32 Patients with a foley -catheter were studied. The study compared the urinary tract infection rate of an experimental group with that of a control group and tested the antibiotic susceptibility of the isolated bacteria. The experimental group(16 patients) was given daily meatal care with 10% Betadine for periods ranging from 4 to 21 days. The control group(16 patients) was not given that care. The results obtained were as follows : 1. The urinary tract infection rate of the experimental group was 50.0 %, and that of the control group 43.8%. There was no significant difference between the groups. 2. Organisms isolated in the control group were bacteria 100%, and in the experimental group bacteria 50% and fungus 50%. The most common organisms of the 15 strains isolated in the total group were Staphylococcus coagulase negative (3 patients), and E-coli (3 patients). 3. Most of bacteria isolated in this study were sensitive to Norfloxacillin, but resistant to Ampicillin, Chloramphenicol, Kanamycin, Tetracycline, and Erythromycin. Hence the importance of controling catheter-associated urinary tract infections. Findings suggest the need to search for other sources of infection, further experimentation controling various sources of urinary tract infection and larger group of subjects.

Background: Pediatric deep neck infection can cause critical complications in that they are seldom able to verbalize symptoms or cooperate with physical examination. The objective of this study is to identify the clinical characteristics according to age. Material and Method: A retrospective study was performed on 26 cases with pediatric deep neck infection during 12 years. Patients were classified infancy group (1-7 yr, 19.2%), preschool age group (7-15 yr, 30.8%) and school age group (15 yr-, 50%). We analyzed the age, sex, sites of abscess, predisposing factors, symptoms and compared onset, hospital date, laboratory and outcomes at each group. Results: In pediatric patients with deep neck infection, the age distribution was 18 males (69.2%) and 8 females (30.8%), the mean age was 7.4 years. The most common infection site was the anterior cervical triangle and submandibular space (19.2%). The most commonly known associated preceding disease was upper viral infection (34.6%), but we could not find the preceding diseases in most of cases (50%). Neck swelling (69.2%) was the most frequent symptom. The mean age of patients who performed neck CT was 8.23 years and neck US was 2.75 years. The younger patients were preferred to perform the neck US than the neck CT (p=0.022). The mean time from disease onset to admission was 9 days in the infancy, 5.5 days in the preschool aged and 5 days in the school aged group. The surgical treatment was performed in 30.8% of school aged, 62.5% of preschool aged and 100% of infancy group. Surgical treatment was preferred to younger patients (p=0.026). Conclusion: Abscess sites, size, and antibiotics susceptibility and especially patient age should be carefully considered in treating pediatric deep neck infection.

The policies developed for the treatment of Helicobacter pylori infection in adults may not be the most suitable ones to treat children and adolescents. Methods used to treat children and adolescents in Europe and North America may not be appropriate for treating children and adolescents in Korea due to differences in epidemiological characteristics of H. pylori between regions. Moreover, the agreed standard guidelines for the treatment of H. pylori infection in children and adolescents in Korea have not been established yet. In this study, the optimal treatment strategy for H. pylori infection control in children and adolescents in Korea is discussed based on these guidelines, and recent progress on the use and misuse of antimicrobial agents is elaborated. Non-invasive as well as invasive diagnostic test and treatment strategy for H. pylori infection are not recommendable in children aged less than ten years or children with body weight under 35 kg, except in cases of clinically suspected or endoscopically identified peptic ulcers. The uncertainty, whether enough antimicrobial concentrations to eradicate H. pylori can be maintained when administered according to body weight-based dosing, and the costs and adverse effects outweighing the anticipated benefits of treatment make it difficult to decide to eradicate H. pylori in a positive noninvasive diagnostic test in this age group. However, adolescents over ten years of age or with a bodyweight of more than 35 kg can be managed aggressively as adults, because they can tolerate the adult doses of anti-H. pylori therapy. In adolescents, the prevention of future peptic ulcers and gastric cancers is expected after the eradication of H. pylori. Bismuth-based quadruple therapy (bismuth-proton pump inhibitor-amoxicillin/tetracycline-metronidazole) with maximal tolerable doses and optimal dose intervals of 14 days is recommended, because in Korea, the antibiotic susceptibility test for H. pylori is not performed at the initial diagnostic evaluation. If the first-line treatment fails, concomitant therapy plus bismuth can be attempted for 14 days as an empirical rescue therapy. Finally, the salvage therapy, if needed, must be administered after the H. pylori antibiotic susceptibility test.
