Purpose: This study aimed to investigate the current status of food service management in elementary care classes. Methods: A focus group interview with seven care class managers and a survey with 101 care class managers using a self-administered questionnaire in Gyeonggi province were conducted. Results: In the focus group interview, purchased meals and snacks were evaluated as low quality by the care class managers. Frequent use of frozen or processed food and products with low prices were also reported as problems. Care class managers were in charge of meal and snack planning without any guidelines or expert advices. The results of the survey show that most schools serve purchased snacks and meals. The average unit costs of one meal and snack were 4,062 and 1,463 Won, respectively. The average unit costs of snacks during semester (p = 0.015) and vacation (p = 0.039) were significantly lower in rural than urban areas. The percentages of schools that prepared nutrition standards for meal and snack planning in elementary care classes were only 7.4% and 10.9%, respectively. The meal menus were mostly provided by catering service companies, and the snack menus were planned mostly by the care class managers. Menu planning by the care class managers was more usual in rural than urban areas (p = 0.054 for meal planning and p = 0.008 for snack planning). Just 33.7% of schools introduced safety standards for food service in elementary care classes, and more than half of the respondents (56.4%) did not do a regular medical check-up. Only 33.7% of the respondents received education for food safety. Conclusion: These results show the necessity for establishment of detailed guidelines for food service in elementary care classes and for the introduction of a food safety and nutrition education program customized for care class managers.

The purpose of this study was to evaluate microbiological contamination of knives and cutting boards in child-care centers. Materials used in this study were swabbed of cutting boards and knives (blade, handle of knife, and joint of handle and blade) in 129 child-care centers. Mean values of total aerobic bacteria of swabs of knives and cutting boards were 1.7±0.7 log cfu/100 ㎠ and 1.7±0.9 log cfu/100 ㎠, respectively. Contamination levels of coliform bacteria from knives and cutting boards were 1.5±0.6 log cfu/100 ㎠ and 1.7±0.8 log cfu/100 ㎠, respectively. Comparing microbiological contamination levels of knives and cutting boards according to type and size of child-care centers, there was no significant difference. Bacillus cereus was detected in knife handles and cutting boards. Diarrhea-type toxin gene (entFM) was detected in B. cereus isolates. Antibiotic resistance tests showed that B. cereus was resistant to β-lactam antibiotics. To reduce microbiological contamination levels of knives and cutting boards in child-care centers and prevent food poisoning from bacteria contamination, continuous education by children's food-service management center is needed for sterilization and disinfection of knives and cutting boards.

Purpose: The aim of this study was to evaluate the dietary behaviors of preschoolers in Daejeon using the Nutrition Quotient for Preschoolers (NQ-P). Methods: The study subjects were recruited from child-care centers and kindergartens located in Daedeok-gu, Daejeon between August and September 2018. A total of 411 preschoolers aged 3 ~ 6 years were included in the data analyses. A questionnaire of NQ-P, which consisted of 14 checklist items on dietary behaviors, was completed by the parents or guardians of the study subjects. The NQ-P scores and its three factors, including "balance", "moderation", and "environment" factors, were calculated according to sex, age, and weight status. Differences in the NQ-P scores and their factors according to sex, age, and weight status were tested using a student's t-test. Results: The mean NQ-P score of the total subjects was $58.5{\pm}9.2$, which was within the medium-low grade. The NQ-P score was $58.5{\pm}9.4$ in boys and $58.6{\pm}9.0$ in girls (p = 0.955). The NQ-P score was similar regardless of the age groups ($57.8{\pm}9.4$ in 3 ~ 4 years vs. $59.2{\pm}9.0$ in 5 ~ 6 years, p = 0.124), whereas subjects aged 5 ~ 6 years showed a significantly higher scores of environment factors than those aged 3 ~ 4 years ($67.9{\pm}16.8$ vs. $61.7{\pm}17.3$). The mean score of the moderation factor was lower in the overweight/obese children compared to the non-overweight/obese children ($46.6{\pm}13.3$ vs. $51.0{\pm}16.2$, p = 0.012). Compared to children aged 3 ~ 4 years, children aged 5 ~ 6 years had higher intakes of vegetable dishes and processed meat. The overweight/obese group showed a higher consumption of processed beverages than the non-overweight/obese group. Conclusion: The current study indicates that the dietary behaviors of preschoolers residing in Daejeon need to be improved. These findings suggest that nutrition education or health interventions targeting young children is necessary for improving their nutritional health status.

The purpose of this study was to evaluate the effectiveness of Centers for Child-care Foodservice Management (CCFSM)'s support on menu management in child-care centers and kindergartens by comparing two perspectives of pre-support vs. post-support and established vs. non-established. To evaluate dietary variety, we used methods that considered both Dietary Diversity Score (DDS) and Dietary Variety Score (DVS). For surveying pre-support and post-support state by CCFSM, we collected and analyzed menus of June and September, 2012, targeting 7 CCFSM supported institutions. Meanwhile, for surveying state in CCFSM established and non-established areas, we collected and analyzed menus of June, 2012, which were implemented in institutions in CCFSM established (181 places) and non-established (106 places) areas. The results of evaluation on the dietary support by CCFSM showed that post-supporting state by CCFSM (95.3%) was significantly higher than pre-supporting state (77.2%) (p < 0.001) and established areas (87.4%) were significantly higher than non-established ones (77.2%) (p < 0.05) on 'Meeting the DRI for infant'. Evaluation of dietary variety between pre- and post-support state by CCFSM showed that post-support state (total 77.3 point) was higher than pre-support state (total 76.4 point). Evaluation of dietary variety between established and non-established areas showed that established areas (total 81.1 point) were significantly higher than non-established ones (total 77.1 point) (p < 0.001). Therefore, it is considered that dietary support service conducted by CCFSM contributes to improve variety level of diet provided by child-care centers and kindergartens.

This study investigated the physicochemical properties and acceptability of yellow layer cake prepared using various levels of wet-milled rice flour (RF). RF was used to substitute 0% (control group), 15% (RF-15 group), 30% (RF-30 group) and 45% (RF-45 group) of wheat flour (WF) to manufacture yellow layer cakes. The substitution of WF with RF showed no significant effect on the pH but decreased the specific gravity and viscosity of the batter. Baking loss rates ranged from 4.65% to 5.03%, showing no significant difference among samples. In the color measurement, the experimental groups showed higher redness (a) and yellowness (b) than the control group (p<0.05). The experimental groups showed lower gumminess and chewiness than the control group. According to the results of intensity measurement of sensory properties, the RF-30 and RF-45 groups showed stronger intensities for darkness, sweetness, moistness and softness than the control group. The acceptance test found that the RF-45 group had significantly higher or similar results for all acceptance attributes than the control group. These results indicate that RF addition as a replacement of WF at a ratio of 45% is optimal for producing yellow layer cakes.

The purpose of this study was to analyze the differences between child-care facilities and kindergartens towards the need for foodservice support by Center for Child-Care Foodservice Management (CCFSM). For this study, questionnaires were sent out from August of 2008 to April of 2009 to directors of 1,478 child care facilities and 299 kindergartens in Seoul and Gyeonggi-do via postal service. A total of 267 questionnaires were usable with 203 (13.7%) of child-care facilities and 64 (21.4%) of kindergartens. Statistical data were analyzed by SPSS 15.0 for descriptive analysis and t-test. For political and administrative support, government funding for foodservice was the highest need and hiring nutritionists was significantly different by type of facility (p < 0.01). Both child-care facilities (4.29) and kindergartens (4.41) demanded the balanced menu from CCFSM. There were significant differences of "information about food material sanitation management" (p < 0.05), "hygiene safety management method according to working process" (p < 0.05), "hygiene safety management method of foodservice facilities and equipment" (p < 0.05). In education and training contents from center, "types and methods to manage foodservice facilities and equipment" for directors, "dietary education by age" for teachers, and "the rules of personal sanitation and working process" and "gas, electricity and fire prevention" for culinary workers had the highest mean score of requirements.

This study investigated the current status and needs of nutrition education to help reduce children's sugars intake, according to the annual budget of the Center for Children's Foodservice Management (CCFM). Through an online survey conducted in October 2015, the 115 CCFMs participated in this survey and they were divided into the following three groups according to the annual project budget: 1~2 million won (${\leq}2M$; n=25), 3~4 million won (3~4 M; n=60), and 5 million and over won (${\geq}5M$; n=30). A total of 8.0% of the ${\leq}2M$ group respondents provided nutrition education on the sugars intake to young children as a main topic, which was significantly lower than those of the 3~4 M(16.7%) and ${\geq}5M$ (16.7%) groups (p<0.05). The most common reasons given for not delivering nutrition education on sugars were "insufficient nutrition education information and materials" for the ${\leq}2M$ (47.1%), and "more urgent nutrition education topics than that" for the 3~4 M (66.7%) and ${\geq}5M$ (50.0%). The percentage of nutrition education on children's sugars intake provided to their parents was low, showing about 8% in the ${\leq}2M$ group, 28.3% in the 3~4 M group and 23.3% in the ${\geq}5M$ group (p<0.05). However, more than 90% of the respondents answered providing nutrition education on sugars intake reduction to children was needed regardless of the annual project budget. The results indicate a great need for the development and dissemination of standardized educational programs about children's sugars intake in order to provide a leveled education program regardless of the project budget, and to solve the difficulties of development and operation of nutrition educational programs due to a lack of budget and human resources of CCFMs with less annual project budget to manage the projects.

Objectives: This study examines the intake of food and nutrients of children according to the employment and working hours of their mothers. Methods: The married women in the source data from the 6th National Health and Nutrition Survey were classified into full-time working mothers, part-time working mothers and housewives according to the working type and the data on their children from 3 to 18 years old were analyzed using SAS 9.4. Results: The group from 3 to 5 years old was the smallest group with 682 children (20.2%), followed by the group from 6 to 11 years with 1,345 children (39.8%) and the group from 12 to 18 years old with 1,355 children (40.1%). The lowest rates for having no breakfast and dinner were observed in the group with housewives (p<0.05). The calcium and phosphorous intakes were the highest in the group with housewives at 61.9% and 126.8%, respectively, and the lowest in the group with full-time working mothers at 54.7% and 115.3%, respectively (p<0.05). The group with full-time working mothers had the highest rate in the calcium and iron intake less than the dietary reference intake at 74.9% and 30.0%, respectively. It indicated that the group with full-time working mothers did not have sufficient nutrients as compared to the other two groups. Moreover, the group with the part-time working mothers showed the high vitamin A intake ratio of 41.4% (p<0.05). Conclusions: This study found evidence of a negative association between mother's employment status and children's diet quality. The employment and economic activity of married women will continuously increase in the future. Therefore, a national nutrition policy is required to provide quality nutrition care for children in the households.

In this study we compared the cognitive function (Mini-Mental State Examination for Dementia Screening: MMSE-DS) and nutrient intake of elderly women with dementia in a long-term care facility (EW-LCF) and a day-time care facility (EW-DCF). This survey was conducted from July 2015 to May 2017 on 73 elderly women with dementia (47 women in LCF and 26 women in DCF) in the city of Incheon. The data obtained from interviews with the subjects and caregivers were analyzed using the SPSS 20.0. The total score of the MMSE-DS and intakes of most nutrients in the EW-LCF were significantly lower compared to the EW-DCF (p<0.05). The nutrient adequacy ratios (NAR) of protein, vitamin A, C, $B_6$, $B_{12}$, thiamin, riboflavin, niacin, folic acid, calcium and phosphorus in the EW-LCF were significantly lower compared to the EW-DCF (p<0.05). However, the indexes of nutritional quality (INQ) of vitamin C, $B_6$, thiamine, niacin, calcium, magnesium, and iron in the EW-LCF were significantly higher compared to the EW-DCF (p<0.05). As a result, the subjects showed an unbalanced and insufficient nutrition intake status regardless of the type of care facility. Most nutrient intakes of the EW-LCF with lower cognitive function were very significantly lower compared to the EW-DCF (p<0.001). Therefore, it is necessary to assess the cognitive function and nutritional status regularly at care facilities for the elderly women suffering with dementia and to provide specialized individual nutritional management.

Objectives: This study evaluated the nutritional status and prevalence of metabolic syndrome of the people who participated in the KNHANES according to the number of household members. They were assessed by using information from the 2013~2014 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 6,088 persons aged 19 years and over participated in 2013~2014 KNHANES, and they were classified into three groups according to the number of household members (single-person, two-person, three-person & over). The dietary behavior, nutritional status, health-related factors and the prevalence of metabolic syndrome of the subjects were investigated with using information from the survey questionnaires of KNHANES. The nutrient intake data of the subjects were obtained by the 24-hour recall method and this was analyzed for evaluating the nutrition adequacy ratio and the index of nutritional quality. The prevalence of metabolic syndrome among the subjects, and according to the study groups, was estimated using the blood and physical measurement data of the subjects. Results: As for EQ-5D index available for all the health states generated by the EQ-5D descriptive system, the single-person household member was the lowest among all the household types. The index of nutrition quality for protein, crude fiber, calcium, phosphorus, potassium, riboflavin and vitamin C in the single-person household was lower than that of the two-person or the three-person and over households (p<0.001). The mean adequacy ratio of single-person households was significantly decreased compared with that of the other types of households (p<0.001). The prevalence of metabolic syndrome was higher in the single-person households than that in the multiple-person households (p<0.001). Conclusions: These results showed that dietary behaviors, nutrition status and health status might be influenced by the number of household members. The results from this study would be useful for improving Korean people's dietary life and health status by implementing evidence-based, specialized intervention for the members of diverse types of households.
