This study examined awareness and information acquisition behavior regarding food hygiene and safety of university students to improve safe dietary practices and to get basic information to develop educational materials for food safety. It was conducted among 276 university students of Qingdao University and Liaocheng University in Shandong province, China through a self-administered questionnaire. Data were analyzed by SPSS Windows V.19.0. To describe characteristics of the respondents, frequency distributions were used. In addition, t test, one-way analysis of variance and Duncan's multiple range tests were conducted. The results were as follows: The respondents were generally interested in food hygiene and safety. However, the level of awareness regarding the food hygiene and safety system in China was not high. Almost forty-five percent of the respondents did not think that foods produced and distributed in China were safe. For the reasons for their distrust, most of the students replied that they did not trust the safety 'because of distrust for hygiene of the food process', followed by 'because of distrust for food distribution' and 'because of excess or illegal use of food additives on food process'. The respondents answered for the concern level toward food hygiene and safety foodborne disease threatened food safety the most, followed by heavy metal contamination and endocrine disruptors. The respondents acquired most information from electronic media including TV and radio. Most of the students wanted to participate in food hygiene and safety education. Finally, when they found hazardous or foreign materials in food the most frequent reaction was 'paying attention in the next purchase', followed by 'notifying others', and 'letting it go this time but never buying that product in the future'.

Powered infant formula and baby food contaminated with Enterobacter sakazakii were reported to cause infection among infants and to be associated with sporadic cases and outbreaks of sepsis, menigitis, cerebritis, and necrotizing enterocolitis. Salmonella contamination of infant formula has also been responsible for multiple outbreaks. Other species of Enterobacteriaceae in powdered infant formula may be causative agents, about which there has been no report. Other pathogenic bacteria have been isolated from powdered infant formula but they were not associated with outbreaks among infant. While Enterobacter sakazakii caused disease in all age groups, premature infants under 28 days old and with birth weight are most sensitive to its infection. Even if low contamination level of the bacteria in powdered infant formula and baby food may not cause infection, the possibility to multiplicate during preparation and storage of reconstituted formula may increase. The etiological factors and pathogenecity of S. sakazakii have not been elucidated. There were wide variability in phenotype and genotype between its strains. S. sakazakii has been isolated from factory facility and surroundings more frequently than Salmonella and thus factory environment should be the source for post-processing contamination of the formula with S. sakazakii. Considering current technology to manufacture power infant formula and baby food it is impossible to sterilize powdered formula but the frequency of outbreak hazard by S. sakazakii can be reduced by pasteurizing the formula base before drying and shortening storage time of the reconstituted formula.

BACKGROUND: Back pain is a popular disease in general population as well as in workers. School students handle heavy bag and keep awkward postures during class long time. However, the prevalence of back pain among students and the risk factors associated with back pain are not well known. METHODS: In this study, we assess the frequency of risk factors for back pain among 2,717 high school students. From April 2001 to May 2001, using a self-reported questionnaire, we collected data on occurrence of back pain and potential risk factors for back pain. RESULTS: Fifteen percent of high school students reported having daily back pain for a week or more during the past 12 months. Female students had a higher prevalence of back pain than males(OR=2.22, 95% CI 1.69-2.91). Using a multiple logistic regression model, we found six factors associated with back pain for females; alcohol(OR=1.75, 95% CI 1.26-2.45), depression(OR=1.75, 95% CI 1.84-2.28), poor physical health(OR=2.57, 95% CI 1.84-8.58), obesity(OR=0.29, 95% CI 0.12-0.68), exercise(OR=l.50, 95% CI=1.07-2.16), and good performance(OR=l.50, 95% CI 1.05-2.18). Only alcohol, however, associated with back pain for males(OR=1.70, 95% CI 1.05-2.77) CONCLUSIONS: High school students had a relatively high prevalence of back pain. Students with alcohol consumption had the higher risk for back pain.

Purpose: This study investigated the current status of post-traumatic stress and related factors among safety managers in Korea National Parks. Methods: The study subjects were 109 safety managers working in Korea National Parks. General characteristics, job-related characteristics, experience of traumatic events and post-traumatic stress were collected by self-reported questionnaires through the mail. The associated factors with post-traumatic stress was analyzed by t-test, ANOVA and multiple linear regression. Results: Overall score of post-traumatic stress was $10.32{\pm}11.37$ and 12.8% was the high-risk group of post-traumatic stress disorder. In simple analysis, score of post-traumatic stress was associated with drinking frequency, disease history, duration of career, delay of rescue, provided the break, rest space and the number of experiences of traumatic events. Finally, the score of post-traumatic stress was significantly higher in subjects who experienced 3 (B=9.141, SE=3.538) or more than 4 (B=11.367, SE=3.063) traumatic events compared to subjects without experience of traumatic event. Conclusion: The score of post-traumatic stress was $10.32{\pm}11.37$ and 12.8% was the high-risk group among safety managers in Korea National Parks. Post-traumatic stress was associated with the experience of traumatic events. Management of safety managers after mobilization or experience of traumatic events will be helpful to decrease of post-traumatic stress.

Background: Limited information is available regarding the associations of various nutrients and periodontitis in Korea. Furthermore, these associations have been controversial in previous studies. Therefore, the present study aimed to evaluate the associations between several nutrients and periodontitis. Methods: Pooled data from the 2007~2010 and 2012 Korea National Health and Nutrition Examination Surveys (KNHANES) were used for the present study. Periodontitis was defined using the World Health Organization (WHO) Community Periodontal Index. All participants completed the Food Frequency Questionnaire (FFQ), which was analyzed using CAN-Pro 4.0. Vitamins A, B₁, B₂, and C, iron, phosphorus, calcium, and protein were selected for analysis. Multiple logistic regression analyses were used to estimate the odds ratios (ORs) for periodontitis. Results: Lower intake of phosphorus (adjusted odds ratio [AOR] = 1.86), calcium (AOR = 1.25), and protein (AOR = 1.52) were associated with periodontitis in males, and lower intake of vitamins A (AOR = 1.32), B1 (AOR = 1.21), B2 (AOR = 1.24), and C (AOR = 1.21), iron (AOR = 1.25), phosphorus (AOR = 1.33), and protein (AOR = 1.27) showed significant relationships with periodontitis in females. In the sociodemographic, somatic, and health behavior-adjusted models, lower phosphorus (AOR = 2.68) and protein (AOR = 1.68) intake in younger males, and lower vitamin A intake (AOR = 1.37) in middle-aged females were significantly associated with periodontitis. Conclusions: The results of the present study demonstrated a significant association between periodontitis and nutrient intake. To avoid an insufficient nutrient supply for a patient with periodontal disease, the patient's diet should be closely monitored.

Background: The coronavirus disease 2019 (COVID-19) pandemic has demonstrated the importance of implementing strategic management that prioritizes the safety of frontline nurse professionals. In this sense, this research was aimed at identifying factors associated with the illness of nursing professionals caused by COVID-19 according to socio-demographic, clinical, and labor variables. Methods: A cross-sectional study was conducted in three Brazilian university hospitals with 859 nursing professionals, which include nurses, technicians, and nursing assistants, between November 2020 and February 2021. We present data using absolute and relative frequency. We used Chi-square test for hypothesis testing and multiple logistic regression for predictive analysis and chances of occurrence. Results: The rate of nursing professionals affected by COVID-19 was 41.8%, and the factors associated with contamination were the number of people in the same household with COVID-19 and obesity. Being a nurse was a protective factor when the entire nursing team was considered. The model is significant, and its variables represent 56.61% of the occurrence of COVID-19 in nursing professionals. Conclusion: Obesity and living in the same household as other people affected by COVID-19 increases the risk of contamination by this new coronavirus.

We surveyed 821 children (ages 12-15 y) in Daejeon city and Cunngcheong province, Korea for their use of vitamin mineral supplements (VMS), either over-the-counter drugs and/or health functional foods (HFF). We also considered the significant variables of VMS use, including demographic characteristics, health-related variables, eating habits and nutritional beliefs of VMS by subjects. The frequency of VMS use was 24.8% and, in comparison to counterparts, it was higher in subjects attending middle school (p<0.001), in those living in a large city (p<0.001), in those with a high monthly family income (p<0.05), and in those with high concerns about school performance by parents (p<0.01). Selfhealth concerns by subjects (p<0.05) and concerns about health of offspring by parents (p<0.01) were higher in users than in nonusers. Eating habits of subjects did not affect the use of VMS. Users had a more positive view concerning the potential health benefits of VMS than did nonusers (p<0.05). Most users took VMS when they were healthy (78.9%) and expected 'disease prevention and health maintenance' (44.6%). However, most users did not feel any special effects from VMS use (58.8%), and they got their information on VMS through family and relatives (53.9%). Users of VMS preferred vitamin C supplements (44.2%) and Ca-supplements (56.9%). Therefore, the results show that VMS use is widely spread among the subjects, and that use of VMS is influenced by multiple variables and subjective criteria. Therefore, practical guidelines on VMS use for children's health and growth should be given through nutritional education.

Purposes: The purpose of this study is to identify and analyze the factors that affect patients reusing non-face-to-face treatments at tertiary general hospitals. Methodology: We retrospectively analyzed a patient's reuse of non-face-to-face treatment from February 1, 2020, to December 31, 2021, at a tertiary general hospital in Seoul within one year of the first non-face-to-face treatment. A frequency analysis was conducted to identify the study subjects' demographic characteristics, treatment type characteristics, disease characteristics, and hospital use type characteristics. Also, across-analysis was conducted to verify the difference in non-face-to-face treatment reuse according to the characteristics a multiple logistic regression analysis was conducted to identify the factors affecting the reuse of non-face-to-face treatment by non-face-to-face treatment patients. Findings: The results of this study can be interpreted as indicating that the following groups are more likely tore use the non-face-to-face treatment: women, children, the elderly, Patients living far from the hospital, psychiatric patients, pediatric patients, medical benefits recipients, chronic patients, patients with mobility difficulties, and patients with high loyalty to hospitals. Practical Implications: When developing a non-face-to-face treatment system in the future, based on the results of this study, it is possible to target patients who prefer non-face-to-face treatment. And this study will be research material for vitalizing non-face-to-face treatment. In addition, the activation of the non-face-to-face treatment system will be an effective means for improving the quality of medical services and generating profits in hospitals in the future.
