The purpose of this descriptive research study was to investigate health beliefs and self-efficacy in respiratory infection management as factors that affect the respiratory infection prevention behavior of college students. The subjects were 178 students attending a university in K city of Gyeongsangbuk-do. Data were collected with a structured questionnaire from September 1st to October 16th of 2020. The results of this study are as follows; Health belief was significantly different from participant's gender (t=-2.86, p=.005), major classification (F=2.95, p=.034), and taking any medications (t=2.18, p=.030). Self-efficacy in respiratory infection management was significantly different from university students' gender (t=-3.56, p=<.001) and major classification (F=4.59, p=.004). Health belief (r=.276, p<.001) and self-efficacy in respiratory infection management (r=.660, p<.001) had a positive correlation with respiratory infection preventive behavior. Multiple regression analysis results show that self-efficacy in respiratory infection management (β=.66, p<.001) significantly affected respiratory infection preventive behavior. The model had an explanatory power of 43%. The findings demonstrate that the major factor influencing the respiratory infection preventive behavior of university students is self-efficacy in respiratory infection management. Therefore, in order to promote behavior to prevent respiratory infection in college students, a program that can strengthen self-efficacy in respiratory infection management should be developed.

146 people working in the ultrasound room in Busan were surveyed, and their perception of hospital infection was analyzed. According to the results of the survey, academic background showed the highest number in terms of awareness and performance of personal hygiene management and hand washing management, and the group with experience of infection education showed the highest number in terms of awareness of ultrasound equipment hygiene, and the group with less than college education showed the highest number in terms of performance of ultrasound equipment hygiene. The difference was statistically significant. Based on the results of this study, performance was lower than awareness in general. This result indicates that the degree of performance is inadequate. Therefore, it can be concluded that individuals need to change their perception of personal hygiene and take interest in it through infection education.

Purpose: The effectiveness of an infection control program is important to hospital quality improvement and decreases of mortality rate and prevalence. Methicillin resistant Staphylococcus aureus (MRSA) is the most common pathogen causing nosocomial infection. The aim of the study was to identify the most important risk factors for acquiring an MRSA, to evaluate the MRSA incidence rates after the nursing intervention in Neurosurgery intensive care unit (ICU). Methods: Clinical data were collected prospectively from December 2008 until July 2009 in Neurosurgery ICU. The patients were divided into preintervention and postintervention groups. An infection was defined as an MRSA if it occurred 48 hr after admission to the Unit. Infection control program including hand washing, education of health care workers about MRSA, standard precaution and contact isolation of patients were applied for three month. Results: A total of 85 patients were included in the study. Forty-five patients of S. aurerus were detected. Among 45 of S. aurerus, MRSA were isolated from 38 patients. The incidence MRSA rate of postintervention group was 26.9% while incidence MRSA rate of preintervention group was 66.7%. In total, The incidence MRSA rate was 44.7%. The incidence of MRSA have decreased in the postintervention as compared with the preintervention group. Conclusion: The infection control program for MRSA was effective to decrease the MRSA isolation rate. The health care workers regular hand washing, education of nosocomial infection control is important enough to be emphasized.

It is well known that Korean red ginseng has various biological activities. However, there is little knowledge about the antiviral activity of Korean red ginseng and its ginsenosides. In this study, we addressed whether oral administration of ginsenoside-Rb2 and -Rg3 is able to protect against rotavirus (RV) infection. The protective effect of ginsenosides against RV infection was examined using an in vivo experiment model in which newborn mice (10-day-old) were inoculated perorally (p.o.) with $1.5{\times}10^6$ plaque-forming units/mouse of RV strain SA11. When various dosages of ginsenoside-Rb2 (25-250 mg/kg) were administered 3days, 2 days, or 1 day before virus challenge, treatment with this ginsenoside at the dosage of 75 mg/kg 3days before virus infection most effectively reduced RV-induced diarrhea. In addition, consecutive administration of ginsenoside-Rb2 (75 mg/kg) at 3 days, 2 days, and 1 day before virus infection was more effective than single administration on day -3. The consecutive administration of ginsenoside-Rb2 also reduced virus titers in the bowels of RV-infected mice. In an experiment to compare the protective activity between ginsenoside-Rb2 and its two hydrolytic products (20(S)- and 20(R)-ginsenoside-Rg3), 20(S)-ginsenoside-Rg3, but not 20(R)-ginsenoside-Rg3, prevented RV infection. These results suggest that ginsenoside-Rb2 and its hydrolytic product, 20(S)-ginsenoside-Rg3, are promising candidates as an antiviral agent to protect against RV infection.

Purpose: The purpose of this study was to describe the perception and practice of hospital infection control of nursing staff in long-term care hospitals by the level of supplementation of nurses. Methods: The participants were 212 nurses and nurse assistants in 13 long-term care hospitals in a metropolitan city and the data were gathered by self-reported questionnaires during August 2011 and analyzed by SPSS/WIN program. Results: The beds per a nurse were 15, and the proportion of nurses among nursing staff in long-term care hospitals was about 33%. In general, the level of infection control in practice was lower than that of perception. The highest perception and practice domain was 'Management of disinfection/contamination', and the lower level domains were 'Personal hygiene' and 'Hand washing' There were statistically significant differences in the hospital infection control of perception and practice depending on age, education, career in long-term care hospital, job position, the quantity of beds, nurse, and nurse assistant, beds per a nurse and proportion of nurses in hospitals. Conclusion: According to these results, the systematic and continual education on hospital infection control of the nursing staff in long-term hospitals should be carried out. In addition, the policy to add more nurses into long-term care hospitals must be implemented.

Monitoring for megalocytivirus infection was conducted for ten months from March to December in 2013 in 15 aquatic farms culturing, red sea bream, rock bream, rock fish and black sea bream around Tongyoung coastal area in Korea, to assess spatial and temporal variability of detection prevalence, and to explore possible links with seawater temperature. In nested-PCR targeted major capsid protein (MCP) gene, asymptomatic megalocytivirus infection was detected in the externally healthy farmed fish with a significant prevalence in range from 0 to 58.3% for ten months. Higher prevalence of megalocytivirus (46.7% - 57.1%) was observed in high water temperature season from September to November than that in other months with lower prevalence of 0.0% to 20.0%. Even though an acute infection of megalocytivirus was occurred in rock bream (positive in the first PCR) with high mortality in one of fifteen farms, there was no expansion or transmission of the disease to the rock fish and red sea bream culturing in net cage just proximal to the rock bream cage in which disease outbreaked. Nucleotide sequence analysis of the cloned MCP gene isolated asymptomatically infected rock fish revealed that the megalocytivirus in this study was clustered together with the rock bream iridovirus (RBIV) under the subgroup II of the genus megalocytivirus (Iridoviridae), which is known to be the major megalocytivirus strain in Korea. The typical histopathological signs were not found in the spleen of rock fish asymptomatically infected by megalocytivirus. Experimental infection of rock bream with the spleen homogenate of the rock fish infected asymptomatically did not induce any mortality unlike the homogenate of infected rock bream with hih mortlity. However, these results may suggest that the asymptomatic infection of megalocytivirus in other fish species can be a potential risk threatening aquaculture industries as a transmission factor of megalocytivirus to susceptible fish species, especially rock bream.
