Bibimbab (mixed rice) is a traditional Korean one-dish meal. This study was carried out to investigate the anti-inflammatory and antioxidative effects of raw and seasoned ingredients used in Bibimbab (Cucurbita moschata P., Platycodon grandiflorum A., Vigna radiata L., Porphyra yezonensis udea, Allium ampeloprasum L., Pterdium aguilinum, Raphanus sativus). Human mast cells (HMC-1) were pretreated with 70% ethanol extracts of Bibimbab and further cultured for an appropriate time after the addition of phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. Cell viability was determined by an MTT assay. None of the ingredients showed cytotoxic effects at a concentration of 1.0 ${\mu}g/ml$. Anti-inflammatory effects were analyzed at 0.01, 0.1, and 1.0 mg/ml concentrations of the raw, seasoned ingredients of PMA. A23187 stimulated HMC-1. Among the various ingredients, seasoned A. ampeloprasum L. extract showed the highest inhibition of TNF-${\alpha}$ and IL-6 secretion (90% and 93%, respectively) at a concentration of 1.0 mg/ml. The R. sativus extract showed the highest inhibition (85%) of IL-8 secretion. DPPH analysis of the antioxidation properties of the ingredients showed that raw and seasoned A. ampeloprasum extracts exhibited the highest DPPH free radical scavenging activity (67.50 and 73.65%, respectively). These results suggest that seasoned ingredients used in Bibimbab have lower anti-inflammatory effects in relation to TNF-${\alpha}$ and IL-6 secretion than raw ingredients in PMA- and A23187-treated HMC-1. In addition, the seasoned ingredients showed a tendency to increase antioxidative activity. Therefore, the ingredients used in Bibimbab have potential as anti-inflammatory and antioxidation agents.

Objectives: The aim of this study was to investigate dietary intakes and nutritional status among Uganda primary school children from two selected schools in urban and rural areas. Methods: Data were collected from 350 pupils (6-14 years) in Mpigi district, Uganda. All participants were offered a school lunch meal (usually maize porridge and boiled beans). Dietary survey was conducted in October 2016. Data for dietary intake levels were collected by the 24-hour recall method with trained school staffs. The data were converted into nutrient intakes using the CAN-Pro 5.0 Program and compared with KDRIs to evaluate the nutritional status of the subjects. Diet quality indexes such as nutrient density, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) and a diet diversity index such as diet diversity score (DDS) were calculated to evaluate nutritional status among subjects. Data were analyzed using SPSS statistical programs. Results: Results show that the intakes of most nutrients were significantly different by schools. The nutritional status of micro-nutrients was very low in both schools according to analysis of nutritional indexes such as NARs and INQs. Students from both schools should improve intakes of micro-nutrients related to child growth such as calcium, Vitamin B₆, zinc and folate. According to the analysis of dietary diversity, there was difference in dietary patterns by schools presumably due to their locations. Conclusions: This suggests that current meals could not provide adequate nutrients for the subjects and urgent nutrition interventions for school food services are needed to improve their nutritional well-being. New foods supplements based on local cuisine are also needed to ensure dietary diversity and sustainable development plans.

The purpose of this study was to investigate basic factors of obesity, nutrient intakes, behaviors of dietary life, daily energy expenditure and emphasize on the necessity of school education. Because the growing prevalence of obesity have required a need for health education in school. The results were as follows. 1. The average height of boys and girls was l59${\pm}$13cm(boys), l54${\pm}$11cm(girls). The average weight of them was 68${\pm}$16kg(boys), 70${\pm}$13kg(girls). BMI(body mass index) of them was 26.9${\pm}$3.4(boys), 29.5${\pm}$2.9(girls). 2. For energy and protein, the average intakes of subjects were higher than recommended dietary allowances for Koreans(7th Ed). The average intakes of vitamin A and ascorbic acid were much lower than the recommended dietary allowances. 3. Most of subjects prefer fast food, rich snacks and overeating, irregular meal amount and these dietary behaviors were severe problems. 4. Total energy expenditure was 1,933kcal in boys and 1,789kcal in girls. To reduce weight and treat obesity, the required energy intake to subjects was 1,546kcal(boys) and 1,431kcal(girls). If we prepared the effective program for obesity, school education should be integrated within the larger community. Parents of students and students may be educated to make good health changes in the home. Nutrition education has a direct impact on their life style of their food intake and nutritional status. The use of multi-component obesity treatments will be effective in a school setting. It is more effective to encourage health habits in school, house and it should be integrated within the larger community.

Food waste in school foodservices is an important factor in managing expense or evaluating the acceptance of served meals and a serious environmental hazard factor in all countries. In this study, the perception and attitude towards food waste reduction and the recognition of environmental pollution of students from elementary school foodservices in Busan, Korea were investigated. The questionnaire was responded by 519 students (boy: 255, girl: 264) in the third and sixth grades. School lunch programs were proved to contribute to the improvement of students' food intake habits. The perception and attitude towards food waste reduction of the third grade students (3.61/3.73) were significantly higher than those of the sixth grade students (3.46/3.59) (P<0.01). Food waste education made a significant impact on the perception and attitude on food waste (p<0.01). When dislike food was supplied the students having the higher perception and attitude towards food waste reduction ate it more than those having the lower perception and attitude. The major reason for plate waste was shown to be influenced by the taste and amount of foods supplied in school lunch programs. Most of students recognized that food waste pollution (4.22) was one of the severest problems among the environmental pollutions, followed by air (4.13), tap water (4.09) soil (3.78), noise (3.55) pollution. The students separated the garbage in the house (72.6%) better than in school and the outside (55.2%). The perception of food waste was positively correlated with the attitude toward reduction of food waste and the recognition of environmental pollution (p<0.01). The attitude toward reduction of food waste was also positively correlated with meal quantity taken (p<0.01).

Purpose: This study was conducted to evaluate the validity of the Gene-Health application in terms of estimating energy and macronutrients. Methods: The subjects were 98 health adults participating in a weight-control intervention study. They recorded their diets in the Gene-Health application, took photographs before and after every meal on the same day, and uploaded them to the Gene-Health application. The amounts of foods and drinks consumed were estimated based on the photographs by trained experts, and the nutrient intakes were calculated using the CAN-Pro 5.0 program, which was named 'Photo Estimation'. The energy and macronutrients estimated from the Gene-Health application were compared with those from a Photo Estimation. The mean differences in energy and macronutrient intakes between the two methods were compared using paired t-test. Results: The mean energy intakes of Gene-Health and Photo Estimation were 1,937.0 kcal and 1,928.3 kcal, respectively. There were no significant differences in intakes of energy, carbohydrate, fat, and energy from fat (%) between two methods. The protein intake and energy from protein (%) of the Gene-Health were higher than those from the Photo Estimation. The energy from carbohydrate (%) for the Photo Estimation was higher than that of the Gene-Health. The Pearson correlation coefficients, weighted Kappa coefficients, and adjacent agreements for energy and macronutrient intakes between the two methods ranged from 0.382 to 0.607, 0.588 to 0.649, and 79.6% to 86.7%, respectively. Conclusion: The Gene-Health application shows acceptable validity as a dietary intake assessment tool for energy and macronutrients. Further studies with female subjects and various age groups will be needed.

The purpose of this study was to evaluate hazard factors in the steps of production, holding and assembly and service of jabchae that were served by contracted management in school meal foodservice. And method of control with the Hazard Analysis Critical Control Point (HACCP)program was suggested. The hazard factors in jabchae product had come from the temperature, time, growth of microbiological equipment and utensils. Almost of raw materials, prepreparation and storage, cooking, holding, serving established the critical control point. It has shown that the microbiological quality of raw materials for jabchae was a little inferior at the time of receiving based on the total plate count(10$^3$∼10 $^{5}$ ), coliform(0∼10$^3$). However microbiological quality become acceptable level by washing and a few disinfection method. Microbiological growth has increased in 3hr at room temperature up to 5.1${\times}$10$^2$ after preparation of jobchae. In conclusion, it is extremly important to reduce hoiding and serving time and to avoid treating food within the danger zone for food safeness. In addition, the prevention of cross-contamination during mixing the ingredients with improper equipment and with insanitary treatments by workers was also important to keep the food safe in this foodservice facility.

Objectives: The purpose of the study is to investigate the relationship between bone mineral density and remaining teeth in Korean adults. Methods: Using National Health and Nutrition Examination Survey(KNHANES) 5th Year 1(2010), 1,985 adults over 50 years old having bone mineral density test were selected. Male adults were 883, and female adults were 1,102. The raw data consisted of general characteristics of the subjects, bone density data, and oral examination data. The questionnaire consisted of general health survey, laboratory examination study, and nutrition study. Data were analyzed using SPSS 18.0 program for multiple regression analysis, ANOVA, t-test. The variables included general characteristics of the subjects, health behavior, diet habit, and oral health behavior. General characteristics consisted of gender, age, residence area, education level, marital status, monthly income, and vocation. Health behavior consisted of smoking, alcohol drinking, body mass index(BMI), physical activity, and mental health. Diet habit consisted of frequency of meal, milk, coffee, and calcium ingestion. Oral health behavior consisted of frequency of tooth brushing, use of oral health care devices, and oral examination. Systemic diseases were measured by the questionnaire for hypertension, diabetes mellitus, and hyperlipidemia. Bone density was measured in T-score of femoral bone, neck of femur, and lumbar vertebrae. Bone density was classified into normal($T-score{\geq}-1.0$), osteopenia(-2.5 < T-score < -1.0), and osteoporosis ($T-score{\leq}-2.5$). The remaining teeth were measured by the differences between normal teeth and missing teeth. Results: Smoking and age are the most influencing factors on the number of remaining teeth and bone density(p<0.01)(p<0.05). Those who had higher bone density, younger age, and nonsmoker significantly had more remaining teeth. Those who were men, diabetic, lowly educated women, and low birth weighted persons tended to have less number of teeth(p<0.01). Conclusions: The study suggested that there were significant differences between men and women according to the oral health management behavior and systemic disease control. Proper management of the oral health and good quality of bone mineral density can reserve the remaining teeth through the whole life.

The purpose of this paper was to investigate the operational status of youth facilities as well as the degree of students' satisfaction with menus served at youth facilities. The survey was conducted from July 9 to July 31, 2013 using questionnaires. The responses of 55 youth facilities and 249 students who had experienced foodservice at youth facilities were analyzed, utilizing the SPSS V20.0 program. The results on management status of youth facilities were as follows: 41.8% of youth facilities were operated for over 10 years, and 45.5% of facilities served meals for 100 to 200 students per day on average. Meal costs were 4,450 won on average, and food costs accounted for 46.8% of average meal costs. Exactly 78.2% of facilities preserved storage type meals at a temperature under -18 degrees Celsius for more than 144 hours, as the 'Food Sanitation Act' stated. Exactly 12.7% of facilities did not hire professional dietitians and had unsupervised foodservice management. Among 19 kitchen equipments surveyed in this research, Combi steamer was the least frequent at youth facilities. According to the results, most students (38.7%) ate leftovers since the food was not tasty. Overall foodservice satisfaction was on average 3.45 points, and the four factors 'dining room sanitation' (P<0.05), 'food taste' (P<0.01), 'serving various desserts' (P<0.01) and 'temperature of dining room' (P<0.05), significantly affected overall satisfaction. As food taste was critical for customer satisfaction, it is important for each dietitian to consider customers' preferences and develop recipes and menus. Further, detailed regulation and precise guidelines for youth facility foodservice are required to enhance students' foodservice satisfaction and serve nutritionally balanced menus in a hygienic manner.

Purpose: The aim of this study was to estimate total sugar intake and sugar intake-related dietary habit and nutrient intake of middle school students. Methods: Subjects included 1,184 middle school students (476 males and 708 females) residing in Jeju. This research analyzed daily dietary intakes of subjects using the 24 hour recall method and surveyed the dietary habit related to total sugar intake using questionnaires. Descriptive analysis, chi-square test, t-test, and ANOVA, using the SAS program were used for analysis of data. Results: The average daily total sugar intake was 60.3 g (male 50.5 g, female 66.9 g). Total sugar intake per meal was 6.5 g (10.8%) from breakfast, 9.0 g (14.9%) from lunch, 11.8 g (19.6%) from dinner, and 33.0 g (54.7%) from snacks. Food groups that contribute to the majority of total sugar intake were grains and their products (23.0 g), milk (11.0 g), fruits and their products (7.3 g), sugars and sweets (6.1 g), and vegetables and their products (5.8 g). In terms of total sugar intakes by cooking methods, desserts showed a greater amount than main and side dishes, and indicated in order of amount as follows: bread and cookies (11.5 g), dairy products (7.5 g), ice cakes (6.2 g), beverages (5.3 g), and fruits (4.5 g). Total sugar consumption was high for rice and side dishes such as noodles (10.2 g), fried foods (2.9 g), stir-fried foods (2.0 g), and cooked rice with seasoning (1.7 g). The daily intake of natural sugar, added sugar, and natural and added sugar was 18.3 g, 35.8 g, and 6.2 g, respectively. The high sugar intake group, which was over 20% of the energy from total sugar intakes, consumed significantly less Fe, Zn, vitamin B6, niacin, and vitamin E than the low sugar intake group, which was below 20%. Conclusion: Total sugar intake of second graders of middle schools on Jeju Island was 60.3 g/day, mostly obtained from snacks (54.7%). Therefore, nutritional education for proper selection of better snacks and for reduction of dietary sugar intake is needed for middle school students.
