Purpose: The purpose of this study was to describe nurses' recognition of, and practice level in management of general nosocomial infections, and methicillin resistant staphylococcus aureus (MRSA) and vancomycin resistant enterococci (VRE) infections. Method: A self-administered questionnaire was used to collect data. Data were collected on June, 2003 from 190 nurses in one university affiliated hospital located in Suwon. Result: The mean score for nurses' recognition of general nosocomial infection control was 3.57, MRSA control was 3.54, and VRE control was 3.86. The mean score on practice for control of general nosocomial infection was 3.19, for MRSA control, 3.20, and for VRE control, 3.63. There were statistically significant relationships between the recognition level and practice level for general nosocomial, MRSA, and VRE infection control. According to the general characteristics of the nurses, the mean scores for both recognition and practice were higher for those nurses who had had infection control education, for those who had worked longer in nursing, and for those who worked in the ICU. Conclusion: It is suggested that appropriate hospital infection control programs should be developed through continuous education and practice to improve nurses' level of the practice in general infection control, and especially in MRSA and VRE infection control.

This study was performed to understand the bacteriologic contamination level of radiological equipments which have frequent contacts with patients in the Department of Radiology of an university hospital in Busan area. Before sterilizing in-patient of the radiology rooms, MRSA, VRE, acinetobacter baumannii, candida albicans, and enterococcus sp. were detected. After sterilization, all the bacteria were not found. As examine times become longer, more bacteria were detected and after 7 hours, bacillus sp.(GPR), CNS, acinetobacter baumannii, and Enterococcus sp. were detected. After examining infected patients, bacillus sp.(GPR), VRE, enterococcus sp. CNS, and micrococcus sp. were detected and on the hands of radiological technologists, CNS, enterococcus sp. escherichia coli, and enterobacter sp. were detected. Similar species of bacteria were detected from each radiology room, but pseudomonas aeruginosa was detected on the handles of portable radiological equipments and the chair in the waiting room. Therefore, it is the most important to regularly sterilize radiological equipments and devices which have frequent contacts with patients and to sterilize them right after the use of infected patients in order to prevent the spread of infection. Also, thorough hand washing, education on infection and management for the characteristics of Department of Radiology should be performed for the systematic prevention of infection.

Avian influenza (AI) viruses are highly contagious viruses that infect many bird species and are zoonotic. Ducks are resistant to the deadly and highly pathogenic avian influenza virus (HPAIV) and remain asymptomatic to the low pathogenic avian influenza virus (LPAIV). In this study, we identified common differentially expressed genes (DEGs) after a reanalysis of previous transcriptomic data for the HPAIV and LPAIV infected duck lung cells. Microarray datasets from a previous study were reanalyzed to identify common target genes from DEGs and their biological functions. A total of 731 and 439 DEGs were identified in HPAIV- and LPAIV-infected duck lung cells, respectively. Of these, 227 genes were common to cells infected with both viruses, in which 193 genes were upregulated and 34 genes were downregulated. Functional annotation of common DEGs revealed that translation related gene ontology (GO) terms were enriched, including ribosome, protein metabolism, and gene expression. REACTOME analyses also identified pathways for protein and RNA metabolism as well as for tissue repair, including collagen biosynthesis and modification, suggesting that AIVs may evade the host defense system by suppressing host translation machinery or may be suppressed before being exported to the cytosol for translation. AIV infection also increased collagen synthesis, showing that tissue lesions by virus infection may be mediated by this pathway. Further studies should focus on these genes to clarify their roles in AIV pathogenesis and their possible use in AIV therapeutics.

One year has passed since the pandemic of COVID-19, which occurred in Wuhan, China, in November 2019 began. Worldwide, as of January 2021, more than 95 million people have been infected, and the death toll is higher than 2 million. In Korea, there are 74,262 infected and 1,328 dead, and government policies such as social distancing to prevent infection are being implemented. Accordingly, many inconveniences occurred in the physical activity environment, such as the closure of various sports facilities. It was necessary to consider physical activities to maintain healthy life while cooperating with the national policy while preventing infection. This study investigated the benefits of physical activity to reduce the risk of trichomoniasis and diabetes, improve bone mineral density, prolong healthy lifespan, maintain activity performance with aging, and improve psychological anxiety and depression. In addition, the physiological changes that may occur in the situation of stopping exercise due to social distancing to prevent COVID-19 infection were reviewed. In addition, moderate-intensity exercise that helps strengthen immune function by activating natural killer cells, neutrophils, and antibody responses was investigated. In addition, it reduces the level and function of blood B-cells, T-cells, and natural killer cells for several hours, decreases phagocytosis of neutrophils in the nasal cavity, increases inflammatory cytokines, decreases immune function, and increases infection. High-intensity exercise was considered. Therefore, in the age of COVID-19, long-term high-intensity exercise such as marathon, which causes impaired immune function, should be refrained from. And you should do moderate-intensity regular aerobic exercise such as fast walking to help prevent infection. It is also recommended to participate in resistance exercises to prevent loss of muscle mass.
