  • Purpose: The purpose of this study was to determine the effects of infection control education, knowledge, attitude and self-confidence of student nurses, regarding nosocomial infection control. Method: This was a nonequivalent control group nonsychronized design. The participants were 83 student nurses who were conveniently assigned to the experimental or a control group. The data were collected from March 5 to June 11, 2008 and analyzed based on Fisher's exact test and t-test. Result: The 1st hypothesis, "Posttest nosocomial infection control knowledge scores for the experimental group will be higher than scores for the control group" was supported (t=2.057, p=.043). The 2nd hypothesis, "Posttest nosocomial infection control attitude scores for the experimental group will be higher than those for the control group" was not statistically significant (t=.466, p=.643), The 3rd hypothesis, "Posttest nosocomial infection control self-confidence scores for the experimental group will be higher than those for the control group" was not statistically significant (t=2.290 p=.025). Conclusion: This infection control education was effective in increasing the levels of knowledge and self-confidence for student nurses regarding nosocomial infection control.

  • This study was conducted with a non-equivalent control group experimental design to investigate the effects of a video-based infection control program through the application of the social cognitive theory on caregivers. Forty-six caregivers were recruited, with 23 pairs being randomly assigned to the control and experimental groups each. While the experimental group took part in the video-based education, the control group was involved in typical lectures. For two weeks, both groups were educated on the principles of infection control, medical and external handwashing, standard precautions, and quarantine. Their knowledge, performance, and self-efficacy were evaluated before and after the program. There was a significant increase in knowledge (p<.001 and p=.005) and infection control performance (p<.001) in the experimental and control groups. Similarly, self-efficacy, self-regulatory efficacy, task-difficulty preference and confidence significantly increased in the experimental group (p<.001). In the control group, only task-difficulty preference significantly increased (p=.005). Consequently, the online video-based infection control education program applying the social cognitive theory proved effective in improving the caregivers' knowledge and performance in infection control, and their self-efficacy. We suggest the use of this program in effective infection control education for caregivers in the future.

  • Purpose: The purpose of this study was to examine the effects of infection control education for families of patients infected with vancomycin resistant enterococcus (VRE). Method: Forty family members of VRE patients were chosen from a university hospital and assigned to the experimental or control group. The experimental group was provided infection control education that consisted of one-on-one instruction using an information booklet, hand-washing video, and demonstration of hand washing practice. Dependent variables were self-reported knowledge and performance of VRE infection control measures, and the number of hand washings when entering and leaving patients' rooms. Results: Knowledge and performance scores were significantly higher for the experimental group compared to the control group. The experimental group washed their hands significantly more often when entering and leaving patients' rooms than the control group. Conclusion: Infection control education for family members of VRE patients was effective in improving knowledge and performance of infection control measures as well as improving the practice of hand washing. Further investigation is needed on the effects of infection control education for families on the actual VRE colonization and/or infection rate.

  • In order to understand the effect of duck hepatitis B virus (DHBV) on the economic performance of ducks, Three groups (DHBV congenitally infected, experimentally infected and DHBV negative) Brown Tsaiya ducks (Anas platyrhyncha) were used for experimental animals. Artificial insemination and pedigree hatching were applied in the propagation of ducklings, and the efficiency of vertical transmission and experimental infection was analyzed through the detection of DHBV DNA in the sera of 8-week-old offspring. The observation of the records of the first year indicated that the persistent infection had no significant effects on the performance of ducks, except the egg number of survival ducks up to 40 week of age. Thus DHBV infection did not appear to give ill effects to the economic performance of ducks in first laying year. A higher infection rate (85.3%) was obtained in congenital transmission than that (75.5%) of experimental infection. Both modes of infection did not reach 100% infectious rate, although some ducks developed transient viraemia in a tracing of DHBV DNA for 24 weeks to 11 challenged ducklings.

  • Purpose: The purpose of this study was to identify the effect of the exchange of saline used in surgical procedures on surgical site infections. Method: Patients with stomach cancer were assigned to the experimental group or to the control group by random sampling, respectively. The experimental group received an exchange of saline during the operation right after the excision of the stomach in a gastrectomy but the control group did not. Data were collected from the medical charts of 34 patients from Dec. 1, 2002 through May 31, 2003. Result: The surgical site infection rate of the experimental group was 5.9% while surgical site infection rate of the control group was 17.6%. In total, the surgical site infection rate was 11.8%. The experimental group maintained a normal level of WBC on post operative day 3; however, the control group, showed an increase of WBC on post operative day 3. Conclusion: The exchange of saline used in an operation immediately after the excision of the stomach in a gastrectomy decreases the contamination level of saline used in the operation, and can prevent surgical patients from a surgical site infection.

  • 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.

  • Purpose: This study was conducted to examine the effects of simulation-based infection control training on the ICU nurses' perception, clinical performance, and self-efficacy of infection control. Methods: Thirty-eight nurses were assigned into two groups using a career stratified randomization. In the experimental group, the subjects received a simulation-based infection control training, whereas the control group participated in a conventional lecture-based training. Two weeks after the completion of the training sessions, the participants were evaluated for perception, clinical performance, and self-efficacy regarding the infection control. Results: The experimental group that received simulation-based infection control training showed an improvement in perceiving the infection control compared to that of the control group, but the difference was not statistically significant. In terms of the clinical performance, the experimental group and the control group scored $26.05{\pm}3.22$ and $18.53{\pm}3.37$ points respectively, demonstrating a statistical significance (p<.001). There was no significant difference between the two groups in regards to the self-efficacy. Conclusion: The developed simulation-based infection control training showed positive effects in improving clinical performance of infection control over conventional lecture-based training, confirming that a simulation-based training is an effective method in advancing the practical performance of ICU nurses.

  • Health state of the Japanese scallop, Mizuhopecten yessoensis, cultured in the Experimental Marine Farm in Minonosok Bay (Peter the Great Bay, Sea of Japan) was investigated. The wide spectrum of histopathological changes has been identified in the internal organs and tissues of scallops: prokaryotic infection with prevalence 100%, destruction of digestive epithelium and other changes in digestive system, infiltration of organs by hemocytes and granulocytome formation. The most affected by prokaryotic infection organs are labial palps, lips, esophagus, intestine and gills. Several of the observed alterations seem to be related to prokaryotic infection.

  • This study was done to analyze the effects of a smear in the nasal cavity against nosocomial Infection. The smear used was mupirocin, and the study centered on infection which constitutes the majority of nosocomial infections called MRSA. The data were collected between March 23 1998 and June 31 of the same year in a university hospital in the Kyongi Province, and is made up of a experimental group of 14 patients who were given nasal cavity smears and a control group of 16 patients who were not given nasal cavity smears. The data were analyzed through frequency and the Chi-square tests and gave forth these results. 1. Of the experimental group 28.6% developed nosocomial infections while 62.5% of the control group developed infections. This difference was significant. 2. In the experimental group, all of the patients developed infections within the first week in the ICU, while 80% of the control group developed infections in the first week and 20% in the second week. The difference was not as marked here. 3. In the experimental group the DM group 66.7% contracted MRSA while 18.2% developed it in the non-DM group showing that the DM group had infection rate was 3.7 times higher than the non-DM groups. In the control group the DM group had a 100% infection rate while 50% of the non-DM group developed it. Overall the DM group's rate infection was 2.4 times higher than the non-DM group. 4. In the experimental group, 37.55% of the patients who had a tracheostomy developed it while 16.7% of the patients who did not have a tracheostomy developed infections. In the control group, 62.5% of the patients who had tracheostomy, and 37.5% of the patients who did not have tracheostomies developed infections. Those who had tracheostomies, and the control group had double the rate contracting infections. From these results we can see that nasal cavity smears are effective against nosocomial infections. In spite of the smears, patients with the diabetes mellitus had a high MRSA infection rate, which requires new alternative treatments.

  • This studies was carried out to investigate a process of formation for the granulomatous lesions in the liver and the haematological variation with the lapse of time after infection of Capillaria hepatica in dogs. Twelve crossbred puppies, about 3 months of age and 2-3 kg of body weight, were administered with 2,000 Capillaria hepatica infective eggs. Every four puppies was sacrificed on 1 week, 3 weeks and 5 weeks after infection, respectively. Although no marked clinical sign was noticed, total leukocyte values were increased peak on 1 week, and then reduced gradually on 3 weeks and 5 weeks after infection. Absolute differential counts of neutrophils and lymphocytes were significantly increased on 1, 3 and 5 weeks after infection. Absolute differential counts of monocytes and eosinophils were trend to increase during the experimental periods. On grossly findings, liver congestions were observed in all infected puppies, and a few white specks were scattered under liver capsule in one puppy on 3 weeks and two puppies on 5 weeks after infection. On microscopic findings, many fresh larvae were observed in the liver tissues in one puppy on 1 week after infection. A worm was decayed and only a portion of cuticle was shown in one puppy on 3 weeks after infection. Around the central necrotic material, the layers of thick macrophages with a few giant cells and lymphocytes with fibrous connective tissues were consisted the granulomatous lesions on 5 weeks after infection.
