The purpose of this study is to present an actual sanitary management conditions and an education plan for school foodservice employees. For assumption verification of this study, basis statistical analysis, factor analysis, and reliability analysis using SPSS V14.0KO were used. Also, regression analysis was conducted for it. The sanitary management actual conditions were shown that a foodservice practice level of middle and high schools was higher than elementary schools. In a scale way, sanitary management conditions of small group schools(500 students below) were lower than large group schools(500~1,000 students). Therefore, it was demanded especially for their employees to manage elementary schools and small group schools. It showed that sanitary consignment education was held irregularly at outside was more effective than the education was held regularly at inside. All the related workers at school foodservice should supply safe foods to schools through more effective sanitary education plan based on the results of effective actual sanitary management conditions.

Objective: This experiment was conducted to investigate the effect of insoluble cellulose supplementation to diets on the growth performance, intestinal morphology, the incidence of diarrhea, nutrients digestibility, and inflammatory responses in altering environmental conditions of animals housing. Methods: A total of 108 male pigs (Duroc×[Yorkshire×Landrace]) were randomly allocated to one of three dietary treatments (cellulose 0%, 1%, 2%) and two environmental conditions (good sanitary condition vs. poor sanitary condition) to give 6 replicate pens per treatment with three pigs per each pen at 14 days post-weaning. Results: Pigs were in good sanitary condition had higher average daily gain (p<0.01) and improved feed efficiency (p<0.05) from day 1 to 14 after weaning compared to their counterparts. The interactions were found between environmental conditions and dietary treatments (day 7: crypt depth [p<0.01], villous height to crypt depth [p<0.001]; day 14: crypt depth [p<0.001], villous to crypt ratio [p<0.01]) in ileum morphology. Crypt depth was decreased (p<0.05), and villous to crypt ratio was increased (p<0.05) only in poor sanitary conditions. Pigs exposed to the good sanitary condition had higher (p<0.05) apparent ileal digestibility (day 7, gross energy; day 14, dry matter), apparent total tract digestibility (day 14, dry matter and crude protein) compared to pigs housed in the poor sanitary condition. Meanwhile, pigs fed a diet supplemented with 2% cellulose had decreased (p<0.05) apparent ileal digestibility (day 7, dry matter; day 14, crude protein), apparent total tract digestibility (day 7, dry matter; day 14, crude protein, gross energy) compared to pigs fed a diet supplemented with 0% or 1% cellulose. Conclusion: Our results indicated that a diet supplemented with 1% cellulose increased villous to crypt ratio, however feeding a diet containing cellulose (1% or 2%) impaired nutrient digestibility for 14 day after weaning in both good sanitary and poor sanitary conditions.

Objective: The study was conducted to investigate the impact of boron supplementation on nutrient digestibility, inflammatory responses, blood metabolites and diarrhea index, and their relevance to growth performance in weaned pigs housed in good and poor sanitary environments for 14 days after weaning. Methods: A total of 108 male pigs (Duroc×[Yorkshire×Landrace]) weaned at 21 days of age were used in a randomized complete block design with 2×3 factorial arrangement. Pigs were assigned to three boron treatments (0, 5, and 10 mg/kg) under two environments (good and poor sanitary) to give six replicates per treatment (3 pigs per replicate). On 0, 7, and 14 days, one pig per replicate was euthanized to collect, ileum tissue samples, and rectal fecal samples. Results: Boron supplementation quadratically influenced (p<0.001) feed intake and weight gain in pigs housed in good sanitary conditions from 1 to 14 days post-weaning where pigs offered 5 mg/kg boron optimized weight gain and feed intake. There is a quadratic interaction (p = 0.019) on feed intake for 1 to 14 days post-weaning where 5 mg/kg boron increased feed intake in good sanitary conditions. Pigs housed in the poor sanitary environment decreased (p<0.001) villus height and crypt depth in ileum at days 7 and 14. On day 7 and 14, crude protein digestibility was quadratically influenced (p<0.05) by boron supplementation. Boron supplementation linearly increased (p<0.05) plasma calcium and cholesterol levels whilst linearly (p = 0.005) reducing plasma triglyceride concentrations. Diarrhea index was quadratically influenced (p<0.05) by boron supplementations regardless of sanitary conditions where 5 mg/kg boron inclusion achieved the lowest diarrhea index. Conclusion: Pigs offered 5 mg/kg of boron increased weight gain which may be deduced by improved dry matter, crude protein, and energy digestibility regardless of the sanitary conditions.

The nursing space and sanitary space are main living spaces for children in the child care center. The purpose of this study is to examine the characteristics in terms of planning by mainly focusing on the nursing space and sanitary space of the disabled child care center in Japan. Since Japan has cultural backgrounds similar to those of Korea while providing systematic child care centers according to the symptom and grade of disability, it is anticipated that this case study on the disabled child care center in Japan will help establish standards related to disabled child care centers in Korea. To conduct the study in a more efficient way, the case study was divided into the space planning of nursing spaces and sanitary spaces and the installation of sanitary tools and handrails in the disabled child care center. The findings of investigating into actual conditions were analyzed by comparing them with Japanese laws and literary and documentary records relevant to this study. Through this study, it is expected that Korean child care centers, having constantly expanded their quantitative growth, will also improve the qualitative level of their atmospheres so that they may provide more proper conditions even for disabled children to get better used to child care centers in Korea.

Seven constructs of sanitary management were evaluated in order to examine perceived performance of sanitary management and sanitary recognition for school food service managers in the Kyunggido area. In order to protect from foodborne illness, 331 (58.4%) responded that the most important aspects were sanitary conditions and stability upon food delivery, and the greatest obstacle was limited availability of facilities and equipment (182, 32.2%). The total mean score for the perceived performance of sanitary management was $4.16{\pm}0.445$ (5-point Likert scale). Among three sectors, personal hygiene management was generally well-conducted with a subtotal mean score of $4.52{\pm}0.458$; however temperature management scored lowest with a subtotal mean of $3.71{\pm}0.630$. Chi-square tests were performed according to general characteristics on the two lowest perceived sanitary management performance areas. In temperature management, there was a significant difference in 5 sectors according to age, and the ages $20{\sim}29$ showed the best perceived performance in all sectors. For serving management, a significant difference (p<0.01) was shown in all sectors. In conclusion, foodservice managers perceive that sanitary management is well-executed. However, the combination of proper equipments and facilities would lead to better perceived management.

Four types of restaurants in Seoul city area were aSsessed in terms of the sanitary conditions and practices, and the microbiological quality. Sanitary check-lists were developed to evaluate the sanitary condition of sampled restaurants. Subjective samples were randomly selected based on the distribution factors of areas, types, and sizes. Microbiological tests on foods, equipments, and utensils were done according to standard procedures and included total plate count and coli forms. Singnificant differences among types or sizes were determined by using one-way analysis of variance. Correlation coefficients were calculated to determine significant relationships between sanitary scores and microbiological counts. The results of the study are summarized as follows: 1) Sanitary condition of kitchen and dining areas as well as the sanitary practices of employees were evaluated as the unsatisfactory state with potentially hazardous practices observed. 2) The microbiological quality of food items with high cooking temperature was in good condition, but most food items showed high levels of microbiological counts mainly due to the improper food handling practices of employees. 3) The sanitary conditions of equipment and utensils which were used at preparation and cooking phases, and food containers which were used at the serving phase, were crucial. Serveal guidelines were suggested for the improvement of the working environment as well as the food Quality.

The purpose of this study was to investigate the food sanitation awareness and performance of foodservice industry employees. Based on a literature review, a questionnaire was developed to identify the food sanitation education, experience, knowledge, and food sanitation practices of the employees. A total of 376 Korean food industry employees participated, and there were 344 usable questionnaires. In the analysis of food sanitation knowledge, the statements "clip fingernails short and do not use nail polish", and "if feeling sick, even with a minor cold, speak to your supervisor immediately", had the highest and lowest percentages of correct answers, respectively. In assessing employee sanitary management practices, many correctly acknowledged "clip fingernails short and do not use nail polish" and "wash hands after using the toilet", which received high scores; however, "use hands to pick up ice" and "if feeling sick, even with a minor cold, speak to your supervisor immediately" had low scores. The sanitary knowledge and practice levels of the employees were not significantly different according to gender, age, work area, job title, or duration of duty. Among the surveyed industries, employees of special restaurants had the least sanitary knowledge(p<0.05) and practice scores(p<0.001). Employees who had worked for $1{\sim}3$ years presented the least sanitary management practice level scores(p<0.05).). In addition, college students and participants without hygiene educational experience showed the least levels of sanitary knowledge(p<0.01). Scores for sanitary management practice were higher when hygiene education was regularly conducted more than once per month. Employees showed significantly higher knowledge and sanitary management practice levels when they were required to use a sanitary checklist(p<0.001), and employees who were trained in HACCP had significantly higher sanitary checklist scores(p<0.05). In foodservices that applied HACCP, the employees showed higher knowledge and sanitary management practice levels(p<0.001).
