The purpose of this study was to investigate the levels of knowledge and behavior towards food hygiene among child consumers, examine the factors influencing them, and analyze the causal relationship between them. The data were collected from 521 elementary school students in Youngnam area by a self-administered questionnaire. Frequencies, Pearson's correlation analysis, multiple regression analyses, and path analysis were conducted by SPSS Windows. The results from this study were as follows. First, the level of knowledge towards food hygiene was not particularly high, and the level of behavior was somewhat more than the average. Second, the factors influencing the level of knowledge towards food hygiene were school record (upper and middle), and concerns about food hygiene. In addition, concerns about food hygiene, the frequency of food hygiene education in the family, and the level of knowledge towards food hygiene had an effect on the level of behavior towards food hygiene. Third, in the analysis of the causal relationship between the knowledge and behavior towards food hygiene, school record indirectly influenced the behavior towards food hygiene, and the frequency of food hygiene education in the family directly affected the behavior towards food hygiene. On the other hand, concerns about food hygiene had direct and indirect influence on the behavior towards food hygiene. In addition, the knowledge towards food hygiene showed a direct effect on the behavior towards food hygiene. These results imply that knowledge towards food hygiene is a very important factor to improve the children's behavior towards food hygiene and that parents' concerns and guidance for children are needed.

Hand washing is an important component of hygiene program for food handlers. Hands can be a source of direct or indirect contamination of foods with pathogenic microorganisms. In this study, the effectiveness of hand washing methods and the use of 70% alcohol solution against transient skin bacteria was tested in an university foodservice facility. 70% alcohol solution is sprayed for 5 seconds automatically when hands are placed in the dispenser. Samples were taken using swab technique in meat cutting area, vegetable trimming area, and vegetable cutting area: before and after washing hands according to planned methods, and after being sprayed with 70% alcohol solution after washing hands. The bacteriological analysis of total plate counts, coliform, fecal coliform of food handlers' hands was done. Statistical data analysis was completed with Mann-Whitney U test and Kruskal-Wallis model using the SPSS program. The levels of initial contamination of workers' hand were significantly different by the work areas($x^2$=9.156, p<0.01). Workers in the vegetable trimming area had more heavily soiled hands than in the other work areas. Mean of TPC counts and coliform was 8.97×$10^5$ CFU/12.4$cm^2$, 2.93×$10^2$ MPN/12.4$cm^2$ respectively, but fecal coliform was not detected. Transient bacteria were removed from hands after washing and using 70% alcohol solution but were not removed completely. Mean reduction percentage in TPC varied among work areas and ranged from 93.19% to 94.99%, and in coliforms from 97.31% to 100%. A significant difference in TPC was found between before and after hand disinfection (Z=-2.714, p<.01) and between standardized hand washing procedures and un-standardized hand washing procedures(z=-2.301, p<.01). Subjects using the hand sanitizer showed a great elimination of TPC(99.45% reduction), but this effect was valid only after following proper washing procedures. Based on the results, the most effective hand washing method was recommended as the combination of the standardized hand washing procedure with warm-water and use of the 70% alcohol solution. The results can be used to develop hand hygiene programs and training strategies for enhancing hand hygiene practices for food handlers in foodservice operations.

Purpose: The purpose of this study is to identify factors related to compliance with respiratory infection preventive behaviors including hand washing, cough etiquette, and oral hygiene of older adults. Methods: A cross-sectional study was conducted with a convenience sample of 100 older adults (mean age: $76.11{\pm}6.35$ years, female: 86.0%). Data were collected from a community senior center through face to face interviews by using instruments including measuring knowledge, perceived threat, self-efficacy, compliance with respiratory infection preventive behaviors. Results: The mean score of knowledge was 7.52 out of 13 in total. The compliance with hand washing with soap was 6.0% for 8 or more times per day. Among the participants, 12.0% adhered to the cough etiquette. Sixty-two older adults (62.0%) didn't use interdental brushes or floss at all. The stepwise linear regression indicated that age and self-efficacy for respiratory infection preventive behaviors were significant factors and explained 24.0% of the compliance with hand washing and the cough etiquette. Education level, cancer diagnosis, and self-efficacy for respiratory infection preventive behaviors were significant predictors of oral hygiene. The factor with the greatest effect was self-efficacy in the two models. Conclusion: The findings suggest that it is necessary to improve compliance with respiratory infection preventive behaviors among older adults using senior centers. In order to enhance the compliance, it is necessary to develop nursing programs based on the self-efficacy for respiratory infection preventive behaviors in the senior centers.

The purpose of this research was to investigate perception, knowledge, and practice level for school food hygiene and need for hygiene education with 300 students of elementary schools in Daegu. The average of correct answer percentage on knowledge about food hygiene of the respondents was 65.3%. For practice level of personal hygiene in school food, the average score was 3.75 out of 5 points. The ratio of educational experience of hygiene and dietary behaviors at home was 73.2%. Almost half of the respondents answered that 'food ingredients' should be the most hygienic. About 90% of the respondents recognized 'hand washing' had effect on prevention of foodborne illness. In addition, the respondents wanted to get the information about food hygiene from 'cooking practice at school', 'school broadcasting', 'education program on TV', and 'school newsletter' in order. These results suggest that continuous education on food hygiene for elementary school students are required and supervision to let them have proper hygiene habit is needed.

To evaluate the effect of lead biomarkers including bone lead on neurobehavioral test in retired lead workers, 131 retired lead workers without any occupational exposure to organic solvent, mercury and arsenic were agreed to participate this study. For the control subjects 56 non-occupationally lead exposed subjects were recruited from same area of retired lead workers with consideration of demographic characteristics. The mean levels of blood and bone lead of retired lead workers were significantly higher than control group and there were significant correlation among other lead biomarkers. Compared with controls without occupational lead exposure, lead exposured subjects had worse performance on 10 tests out of 12 neurobehavioral tests, but only two tests(Purdue pegboard nondominant and both hand) showed statistical significance of differences. In multiple linear regression analysis of neurobehavioral tests with lead biomarkers and demographic and lifestyle variables, age was associated negatively with 11 neurobehavioral tests, whereas log-transformed ZPP was associated with Purdue pegboard(both hand) and Santa Ana manual dexterity(non-dominant hand). On the other hand, tibia lead was associated Pursuit aiming test(correct) and Purdue pegboard(dominant hand) and calcaneal lead was associated with Purdue pegboard(dominant hand). This study confirmed that among all relevant variables age was most significantly associated with the poor performance of neurobehavioral tests. The blood lead did not have any significant association with neurobehavioral tests, but tibia and calcaneal bone lead and blood ZPP showed significant association with a few tests even after more than mean 9 years from their retirements.

This study was designed to characterize endotoxin-induced prostaglandin production in primary cultured rat vascular smooth muscle cells (VSMC). The time course for prostaglandin synthesis in lipopolysaccharide (LPS)-stimulated VSMC showed that the maximum production was reached in 12 hours. LPS induced prostaglandin H2 synthase (PGHS) activity in VSMC and the time course profile in the changes of PGHS activity paralleled that of total prostaglandin production. Differential treatment showed that 4 hours' exposure to LPS was enough for the maximum effect on the prostaglandin production and this effect was completely inhibited by the co-treatment of actinomycin D, a transcription inhibitor. These results suggest that LPS effect might be determined within 4 hours. Actinomycin D increased PGHS activity without affecting prostaglandin production if added 4 hours after LPS treatment. On the other hand, cyclogeximide, a translation inhibitor, augmented LPS-induced prostaglandin production if treated during first four hours, but it inhibited LPS-induced PGHS activity regardless of treatment schedule. These results suggest the existence of multiple regulating mechanisms in the LPS-induced prostaglandin synthesis.

Purpose: This study was conducted to examine the effect of education on infection control for multidrug resistant organism (MDRO). Methods: One group pre-post time series design was used. Infection control education for MDRO infection was provided to nurses working in the Neonatal Intensive Care Unit (NICU). Knowledge and recognition were evaluated before and after education. Hand hygiene compliance, MDRO isolation rate and central line-associated bloodstream infection (CLABSI) rate were used as outcome variables. Data from 45 nurses was used for analysis. Results: General knowledge about MDRO increased (p=.011). Responses to questions about image of MDRO and MDRO management tended to change in a positive direction (p=.046). Hand hygiene compliance was 100% at pre-test, 79.5% during education period and 98.4% at post-education period. MDRO isolation rate was 6.83 per 1,000 patient days at pre-test, 10.24 during education period and 6.68 at post-education period. CLABSI rate was 3.76 per 1,000 central line days at pre-test, 6.84 during education period and 4.71 at post-education period. Conclusion: Findings indicate that the education program is effective in improving knowledge about MDRO in NICU nurses. However, more reliable indicators should be used to determine long-term effects.
