The purpose of this study was to suggest a stratege of promoting school health. This study examined the historical aspacts of school health and conducted a mail questionnaire survey for 24 school health specialists who work in school and educational administration from November 1 to November 30, 2000 and the reply rate was 79.2%(19 persons). The results were as follows. The most important fields in schools were answered health related field. The most important field of school health were health education(89.5%), the supervisor of school health project should be office of school health ward in Educational administration(42.1%), and problems in conducting health project in school were lack of policy(63.5%), awareness of the importance of school health(63.2%), and budget(63.2%). They answered that the cause of food poisoning in school were negligence of sanitation of cook(42.1%) and prevention methods were thorough inspection of food stuffs(31.6%). 72.2% replied that school health project were not being operated in a proper way. They answered that tasks of promoting school health were development of school health policy, increase of man-power for school health, expansion of school health budget, systematic health education, and development of independent health subject program, connection with local society. 94.7% of those replied answered that school health organization is necessary. Common sense on health and sex education are needs to be handled most importantly in health education. 63.2% of those replied answered that appropriate time of education for health service is more than once a week. The person appropriate for health education were school nurse(63.2%). In conclusion to improve the problems of school health and to activate it, development and support of policy of health project and preparation of various conditions that can establish health courses independently is, above all, immediately required. Many efforts need to be made to make the president of schools and education authorities recognize the importance of health in schools. These efforts need to link to the transformation of awareness, and process of development of concrete method of practicing various school health education and school health is necessary.

Lactic acid bacteria with antibacterial activity can be effectively used as probiotics to inhibit the growth of harmful bacteria that cause food spoilage or food poisoning. In this study, Pediococcus pentosaceus M132-2, isolated from soybean paste, was analyzed for its effects on three major contaminating fungi. M132-2 was confirmed to exert antifungal activity by inhibiting the growth of all three fungi tested. In addition, M132-2 displayed excellent salt resistance and low temperature tolerance. Thus M132-2 can survive at the salinity level in cheese and at the low temperatures used in the aging process. Finally, when supernatant from an M132-2 culture was applied to Gouda cheese, the growth of contaminating fungi was significantly inhibited. Consequently, M132-2 may be useful for the prevention of spoilage of various foods, including cheese.

The purpose of this study was to provide basic data necessary for the prevention of food poisoning and safe food management. We examined 872 food samples for B. cereus in accordance with the MFDS Food Code and investigated characteristics of their harboring toxin genes. We detected and isolated 113 strains of B. cereus from 78 food samples (8.9%), and the average detection level was 48 CFU/g. B. cereus isolates carried at least 1 toxin gene among the emetic toxins and 5 enterotoxin genes. The toxin gene profiles of B. cereus were classified into 18 different types of isolates showing genetic diversity. Among the strains, 34 (30.1%) had all 5 enterotoxin genes (Cytk-nheA-entFM-bceT-hblC), accounting for the highest percentage. The entFM and nheA genes were major enterotoxin genes, while the emetic toxin gene, CER, was the least detected in B. cereus isolated from food samples.

The purpose of this study was to assess the need for nutritional education in male workers living in Busan, Korea. This study surveyed 310 industrial workers at five companies in Busan using a questionnaire. According to the results, need for nutritional education scored 3.60/5.00 points. The usage rate of mass media as a means of acquiring nutritional information was significantly higher (P<0.001) in subjects in their 50s compared to other age groups. Regarding scores on need for nutritional education according to theme, 'balanced eating habits' showed the highest score, followed by 'food safety', 'diet therapy related to a disease', and 'food hygiene and food poisoning prevention'. In terms of frequency of nutritional education, 29.0% of subjects considered 'biannually' to be desirable, whereas 25.8% and 21.0% considered 'annually' and 'quarterly' to be desirable, respectively. The results of this study suggest that nutritional education for industrial workers should be implemented in various ways in accordance with their characteristics. Furthermore, considering workers' low awareness levels of the need for nutritional education, employees are required to take the education in order to encouraged to improve their nutritional status and commit to a desirable diet.

Recently pathogenic E. coli is one of the main foodborne pathogens resulting in many patients in Korea. To understand the characteristics of pathogenic E. coli outbreaks in Korea, the epidemiological investigation reports of pathogenic E. coli outbreak in 2009 (41 reports) and in 2010 (27 reports) were collected in the web site of the Korea Centers for Disease Control and Prevention, reviewed and analysed in this study. The main places of the pathogenic E. coli outbreaks were food catering service area (64.8%) and restaurants (25.0%). The main type of the pathogens were EPEC (44.7%) and ETEC (34.2%). EAEC and EHEC was responsible for 10.5 and 9.2%, respectively. Eight of 68 outbreak cases were caused by more than 2 types of pathogenic E. coli which implicates the complicated contamination pathways of pathogenic E. coli. The incidence rate of pathogenic E. coli was $33.6{\pm}30.5%$ and the main symptoms were diarrhea, stomach ache, nausea, vomiting, and fever etc. The two identified food sources were identified as frozen hamburger pattie and squid-vegetable mixture. To improve the food source identification by epidemiological investigation, food poisoning notification to the agency should not be delayed, whole food items attributed the outbreak should be collected and detection method of the various pathogenic E. coli in food has to be improved. In conclusion, the characteristics between the EHEC outbreaks in the western countries and the EPEC or ETEC outbreaks in Korea needs to be distinguished to prepare food safety management plan. In addition, the development of the trace back system to find the contamination pathway with the improved detection method in food and systemic and cooperative support by the related agencies are necessary.

Most elderly have difficulties in managing food safety and nutrition by themselves. Various nutrition educations for the elderly have been developed, but food safety and nutrition education program and educational tools for the elderly are very limited. The aim of the study was to evaluate a food safety and nutrition education program based on the Health Belief Model (HBM) for the elderly. Education program was implemented for 220 seniors (137 educated group and 83 control group) aged over 65 years at senior welfare community centers. The intervention study was carried out on a weekly basis during each of 5 weeks, and each session lasted about 35 or 40 minutes. The effectiveness of the program was assessed with a questionnaire before and after education. Education program consisted of a 5 week program, and topics were 'Dietary changes for the elderly's healthy life', 'Prevention of food poisoning in everyday life', 'Safe food handling for my health', 'Healthy dietary life to prevent chronic disease', and 'Safety! nutrition! healthy dietary life'. Education program materials such as slides, handouts, videos, leaflet, and booklets were developed. As a result, there were score improvements in knowledge, dietary behaviors, and health belief after intervention in the intervention group, which were higher than those of the control group. In particular, there was a meaningful interrelation between dietary behavior and health belief (r=0.520, P<0.001). This finding suggests that changing beliefs is very important to make desirable dietary behavioral changes. For this reason, we can conclude HBM theory is an effective model to educate nutrition and food safety for the elderly. Furthermore, food safety and nutrition education programs are implemented and delivered continuously at various settings such as a health center or community welfare center, and those will contribute significantly to enhance perception and change their desirable dietary behaviors for the elderly.

This study was conducted on 4th and 5th grade elementary school students in Daegu, Korea for the purpose of promoting health and proper dietary habits. A children food safety education program was developed and its effects evaluated on 4th and 5th graders (3,932 students for 4th year, 4,438 students for 5th year) at 46 elementary schools, which were under the jurisdiction of the four educational bureaus of Daegu city. Education was conducted in accordance with an education design plan, of which there were two goals, including know the contents of 'special act on children's dietary life safety management' and 'practice proper hand-washing'. 'Special act on children's dietary life safety management' was explained, and the education curriculum included proper hand-washing for prevention of food poisoning, quality certification mark on children's favorite foods, harmful foods such as unsanitary and adulterated foods, and green food zone. Flash songs, PowerPoint, 'glitter burger' notice note, and banner were used as education media. It was found that the awareness level of items related to 'special act on children's dietary life safety management' increased significantly after education (p<0.001). 'Necessity of nutrition education and children's food safety' also increased significantly (p<0.05) after education. Lastly, children answered that they washed their hands more often after education (62.9%) than before (60.7%).

The monthly distribution of marine bacteria in the coastal waters of Chung-Mu was investigated from April, 1976 to March, 1977. The aim of this study was to obtain basic data for the prevention of food poisoning and for the efficient aquaculture of the area. Samples of sea water, mud, fish and shell fish were taken every month. The results are as follows: 1. One thousand four hundred and twenty-six strains were isolated from 732 samples of sea water, mud, fish and shell fish. They were 450 strains of Pseudomonas fluorescens, 422 strains of Achromobacter liquefacience, 72 strains of Vibrio parahaemolyticus, 234 strain of Vibrio alginolyticus, and 248 strains of Proteus vulgaris. 2. V. parahaemolyticus occupied $9.84\%$ of the total samples and $52\%$ of them were found in the sea water and mud. 3. The muds sampled districtly beneath the aquaculture raft contained much gas. They seemed to originate from the deposition of excretion of shell fish. The fatness of the shell fish was low where the gas was abundant. 4. It was .found that the shell fish with low fatness contained much Vibrio sp. 5. Regional distribution shows that marine bacteria were abundant in the order of station 10, 9, 8, 11, 1. The area around station 9 was polluted by reclamation of the area, and station 8 showed the influence of the excrement treat tank located nearly.

Background: Despite the rise in the number of domestic indoor climbing gyms, there is a lack of specific hygiene standards and research on the holds installed in them. Holds can act as vectors for microbial transmission through the hands, posing a risk of infectious diseases, especially with damaged skin. Objectives: The aim of this study is to investigate the contamination level and species of microorganisms on holds according to the management methods practiced in indoor climbing gyms and identify effective strategies for reducing microbial contamination. Methods: We investigated factors that may influence microbial contamination of holds, including hold management methods, user information, and hygiene management at three climbing gyms in Seoul. A total of 72 holds were sampled, 18 for each management method of brushing, high-pressure washing, and ethanol disinfection. Samples were cultured on LB and blood agar at 37℃ for 48 hours to calculate CFUs. PCR assay targeting 16S rRNA was carried out to identify microorganisms. Dunn-Bonferroni was employed to see the microbial reduction effect of the management method and the difference in microbial contamination by management method and climbing gym. Results: As a result of microbial identification, microorganisms such as Bacillus, Staphylococcus, and Micrococcus, which were derived from various environments such as skin and soil, were discovered on the surface of the climbing hold. Among the discovered microorganisms, some species had potential pathogenic properties that could cause food poisoning, gastrointestinal disease, bacteremia, and sepsis. All hold management methods were effective in reducing microorganisms (p<0.05), with ethanol disinfection being the most effective (p<0.001). Conclusions: Our results indicate that there are potential pathogens on holds that demand thorough management for microbial prevention. Proposed methods include regular brushing and ethanol disinfection in addition to high-pressure washing with long cycles, which are the existing forms of hold management. Further studies on shoe management are advised to curb soil-derived microorganisms.
