The purpose of this study was to evaluate the foodservice management practices in child-care centers in order to provide basic information for the development of a model of a centralized food service information center. This approach was achieved using a variety of qualitative and quantitative information including general foodservice management practices and plate waste. A self-completed questionnaire survey of 651 child-care centers in Korea was undertaken and detailed information was carefully collected at 6 representative child-care centers. The results of the empirical survey were as follows: 1. Child-care centers categorized by location were in large cities (59.9%), medium cities (27.6%) and in provincial areas (12.5). 2. Private sector of child-care centers was 46.4% of the total followed by National/public (44.2%) and licensed home day-care programs (9.4%). 3. Total average number of children in child-care centers was $63.3{\pm}43.1$ with a very significant difference (p<0.001) in types of child-care centers. 4. The average space of kitchen and dining room was $5.0{\pm}3.8\;and\;10.8{\pm}11.0$ pyung ($1pyung=3.3058\;cm^2$). 5. The average cost of interim snack in morning and afternoon in child-care centers were $345.9{\pm}459.3$ won and $359.3{\pm}226.6$ won respectively. The average cost of lunch was $644.0{\pm}481.1$ won. There was a significant difference (p<0.001) by types of child-care centers with a highest cost of 863.9 won in licensed home day-care programs. 6. Only a limited number of dietitian were employed, therefore most of food service management practice was not conducted by professional personnel. 7. The result of nutritional analysis of the food revealed that the level of energy and nutrients contained in the food was below the recommeded level (RDA/3).

A survey of 113 children, aged 4 to 6 years, of the San Cheon a day care center, located in the upland, over populated, poor area of Seoul City, was conducted from July 28 to September 6, 1982, to investigate the dietary and nutritional status, and prevalence of parasitic inpection. House size was 10.1 Pyung; number of households per house, 3.1; number of family member per household, 4.8; and number of family members living together per room, 3.7; on the average. Only 49% of households possess own houses and the others live in the rented houses. About 40% of mothers were engaged income-producing activities within or outside of the home. Mean values of height, weight, arm circumference, girth of chest, and girth of head ranged from 98.4 to 102.2% of KIST mean. However, 13% of the subjects were assessed as undernutrition for 'weight for height'. Mean value of hemoglobin was $12.9{\pm}2.9\;g/dl$ and mean hematocrit value was $35.2{\pm}5.5%$; 17.9% of the subjects were proven to be anemic according to the criteria of the WHO. The positive prevalence of parasitic inpection was 3.3%, significantly lower than that observed in any other area, probably because of community parasitic control project. Intakes of energy and nutrients except thiamin and ascorbic acid were far below RDAs. Carbohydrates for energy provided 71. 2 to 73.8% of total energy intake; protein accounted 11.3 to 12.2%; fat provided 14.5 to 16.6%. Energy intake was divided among breakfast, lunch, evening meal and snack, on the average, in a percentage of 22.0; 23.4; 24.4; 30.2. There was significant correlation between pattern of food consumption and nutrient intakes. The nutrient intakes and quality of foods were highly correlated to the maternal factors, especially mother's educational level. The study suggested that development of nutrition guides for mother and children would be needed to improve nutritional status of those young children.

The purpose of this study was to compare weight control behaviour, eating habits and health-related life habits according to the obesity degree by body fat percentage (%Fat) among middle-aged women. The subjects were 170 middle-aged women who lived Gunsan City, and they were assigned to one of the following groups based on their %Fat; normal weight group (18% - < 28%), overweight group (28% - < 33%) and obesity group (over 33%). The height, body weight, %Fat, the circumference of waist and hip of them were measured. Eating habits and health-related life habits were evaluated based on questionnaires. The results were as follows. Their weight, %Fat, body mass index (BMI), relative body weight (RBW), waist, hip, and waist-hip ratio (WHR) were significantly higher in the obesity subjects when compared to the normal and overweight subjects. Self-perception for weight (p < 0.001), desire for weight control (p < 0.01), and reasons of weight control (p < 0.05) were different among three groups. The main skipped meal was breakfast (67.9%), reasons of skipping meals were different among three groups (p < 0.05), and main reasons were "lose one's appetite" and "have not enough time". Food habits score for each food was not significantly different among three groups, but eating the meal on thinking with food combination in normal group was higher than overweight and obesity group (p < 0.01). Correlation coefficients of food habits score and anthropometric measurements were that salty of food was negative and food habits scores were positive correlation for anthropometric measurements and obesity index (p < 0.05 - p < 0.001). Frequency of exercise and fitting exercise for body were different among three groups (p < 0.05). Obesity group was lower frequency of exercise than the other groups. Regular diet was positive correlation with food combination (p < 0.01), taking fish (p < 0.05), taking vegetables (p < 0.01), taking bean products (p < 0.01) and food habits score (p < 0.01), frequency of eating out and snacks were negative correlation with taking fruits and fishes. Therefore, proper nutritional education for middle-aged women in obesity group is recommended regular diet, good food habits and exercise. The middle-aged women must decrease the frequency of eating out, snack and the salty foods, and increase the fruits and vegetables. They must have healthy life styles for exercise, smoking, and drinking.

본 연구는 칼슘과 철 그리고 철과 아연의 상호작용과 신뢰성있는 영양정보를 제공하기 위해 영양강조표시제품 중 칼슘, 철, 아연의 함량을 분석하고 표시량과 분석값을 비교하였다. 칼슘, 철, 아연을 강조표시한 제품(시리얼, 과자, 두유, 초콜릿가공품, 기타코코아가공품, 당류가공품, 과줆채음료, 고형차) 총 42건을 수거하였으며 칼슘, 철, 아연은 무기성분의 건식분해법으로 전 처리한 후 Inductively Coupled Plasma Spectrometer (ICP)로 실험하였다. 칼슘이 강조표시된 제품 42건에 대한 표시량 비율은 87~176%이었으며, 철이 강조표시된 제품 13건에 대한 표시량 비율은 84~167%, 아연이 강조표시된 제품 6건에 대한 표시량 비율은 98~275%였다. 모든 분석값이 표시량 대비 80% 이상으로 식품 등의 표시기준을 충족하였다. 칼슘과 철의 상호작용은 한국인의 칼슘 섭취가 1일 권장량의 68.7% 수준으로 부족하므로 칼슘의 과다섭취로 인한 철의 흡수방해는 우려할 만한 상황은 아닌 것으로 보인다. 또한, 분석한 영양강조표시제품의 철과 아연의 함량 비율이 1.53:1이 최대였으므로 철의 과다섭취로 인한 아연의 흡수방해는 우려할 만한 상황은 아니었다. 그러나 업체에서는 칼슘, 철, 아연을 강조한제품을 생산할 시에 영양소의 상호작용을 고려하여 생산을 해야 할 것이고 소비자에게 정확한 영양정보를 제공하고 적정량의 영양섭취를 위해서는 지속적인 모니터링을 통해 식품표시에 대한 주기적인 관리가 필요할 것으로 생각된다.

BACKGROUND/OBJECTIVES: The Recaller app was developed to help individuals record their food intakes. This pilot study evaluated the usability of this new food picture application (app), which operates on a smartphone with an embedded camera and Internet capability. SUBJECTS/METHODS: Adults aged 19 to 28 years (23 males and 22 females) were assigned to use the Recaller app on six designated, nonconsecutive days in order to capture an image of each meal and snack before and after eating. The images were automatically time-stamped and uploaded by the app to the Recaller website. A trained nutritionist administered a 24-hour dietary recall interview 1 day after food images were taken. Participants' opinions of the Recaller app and its usability were determined by a follow-up survey. As an evaluation indicator of usability, the number of images taken was analyzed and multivariate Poisson regression used to model the factors determining the number of images sent. RESULTS: A total of 3,315 food images were uploaded throughout the study period. The median number of images taken per day was nine for males and 13 for females. The survey showed that the Recaller app was easy to use, and 50% of the participants would consider using the app daily. Predictors of a higher number of images were as follows: greater interval (hours) between the first and last food images sent, weekend, and female. CONCLUSIONS: The results of this pilot study provide valuable information for understanding the usability of the Recaller smartphone food picture app as well as other similarly designed apps. This study provides a model for assisting nutrition educators in their collection of food intake information by using tools available on smartphones. This innovative approach has the potential to improve recall of foods eaten and monitoring of dietary intake in nutritional studies.

The primary purpose of this research paper is to study the nutrition intake status of high school students and their physical growth and development. Further, it made an attempt to find and define nutritional problems and assist in their growth and development through proper nutritional management. One hundred students in both sexes, first year grade in senior high school were provided with questionnaires. For six days the respondents filled out the questionnaires. They were asked to keep record of what they ate each meal. Their nutritional intake were analyzed in accordance with what they ate. Findings, conducted on percentage, CR test, t test, and F test, were as follows: 1. For the living circumstance a) Average numbers of brother and sister in sampled family were four. b) Seventy to eighty percent of the students were brought up by mother's milk at their infants and approximately 40% of students were weaned at the age of 7 to 18 months. c) Fifty percent of the respondents revealed irregulity in their meal time. d) Monthly average expenditure for daily food reached $20{\sim}40%$ out of total income. e) The most favorite foods reflect as follows: The most favorite main dish is boiled rice and side dish beaf. Fruits. juice, milk, ice cream are more popular snack among whole students. 2. Nutrition survey a) Calory sad nutrients were found to be below the recommended level, especially in calcium, vitamins A, $B_2$ and C. b) The total calory intake were composed of 73% from carbohydrate, 14% from protein and 13% from fat in the case of boys. The girls were 65%, 14%, 21% respectively. c) Both boys and girls in their animal protein intake averaged about 33% out of total protein intake. d) Meat consumption of the majority respondents were proportionate in $10{\sim}20%$ in their total food consumption. 3. The result of statistical analysis were as follows: a) Statistical significant differences in the relationship between the calory intake and physical growth index were observed at the level of p<0.05. b) Statistical significant differences in the relationship between the protein intake and physical growth index were observed at the level of p<0.05. c) Statistical significant differences in the relationship between meal time and physical growth index were observed at the level of 0.02<0.05. d) No statistical significant differences in the relationship among calory, protein intake and school records as well as intelligence were found. The experiment indicated that there is a direct relationship between nutrition and the physical growth and development, whereas There seems to be an indirect relationship between nutrition and intelligence.

This study examined the eating habits and preferences of foods according to the age of children with autism spectrum disorders and identified the nutritional needs of parents to support their healthy eating habits and provide basic data for the development of educational programs. A survey of 100 parents of children with autism spectrum disorders was conducted on their children's snack intake, food preferences, and parents' nutrition education needs. As a result, there were four times more boys than girls, and the body mass index differed according to age (p<0.001). Most children ate snacks more than once a day, and parents found that they wanted to develop nutritious snacks that could replace high-protein, low-calorie meals with the minimal use of additives. For the food preference, there was a significant difference in grains and starches, vegetables/seafood and fruits, milk and dairy products (p<0.05), fats and sugars, and Korean fermented pastes (p<0.01) between the two age groups. Regarding whether nutrition education was required, many parents had a high demand for nutrition education (4.24±0.70), and the intention to participate was 3.62±1.09. The most important content to be dealt with in parent education was 'Inducing a change in bad eating habits and behaviors', which was the highest (63%), and mostly face-to-face education was preferred. In conclusion, young children require diet education, and older children need to focus on weight control and obesity.

Recently the rural Korea has been remarkedly changed of family and social value in accordance with the development of industry. The lower economic class made by social economic growth is widespread with increasing aged, specially odd pair family in rural. The purpose of this study was to investigate to help and keep improve health of rural lower economic class, family system by comparing and analyzing the dietary management, between pair and odd pair family, and to get the data helpful the right guidance for rural. The subjects 1870 collected in 9 provinces by sampling with probability proportional to size (PPS). Questionnaire about dietary habit, food cultivation, production and preservation survey was conducted by trained interviewers. The main results were as follows : 1) The characteristics of odd pair families, head of household was female(77%), over 65 years(84.9%), small family(1.76 persons) and lower education(male 7.5 years, female 3.1 years) status. 2) As the states of diets of odd pair family, having breakfast(87.1 %) but one or two kinds of side dishes(31.3 %) only possible to guess lower status of food intake balance. Nutritional supplements(21. 7 %) was lower than that of paired family. 3) The aspects of dietary habit of odd pair family, no instant foods(70.7%), no snack(38.4%) no dine out(69.2%) were common. 4) Dietary habit scores were 7.78 points of odd pair family compared 8.34 points of paired family. 5) Food purchase place of odd pair family was market(44.2%) but super-market(42.7%) of paired family. 6)In odd pair family, seldom traditional dish preparation(62.0%) but prepared winter kimchi(81.9%), comparing seldom traditional dish(38.6%) and winter kimchi(96.4%) in paired family. 7)The food cultivation state was surveyed, pepper( 42.2 %) and chinese cabbage( 43.9 %) were consumed after cultivation, but sesame(59.4%), bean sprout(90.2%), tofu(92.8%) and egg(93.3%) were consumed by purchase in odd pair family.8) Food cultivation score of odd pair family was 2.98/12points significantly lower than 4.50/12 points of paired family(p<0.01). 9) At the status of fermentation food production in odd pair family, Duenjang(72.1 %) and Gochujang(69.7%) Kanjang(68.3%) Kimchi(82.1 %) and Meju(68.3%) were high rate of production, but more frequently producted in pair family. 10) The score of fermentation food production of odd pair family was 8.57/12points but significantly lower than 10.24/12 points of pair family(p<0.0001). 11) Food preservation score 0.48/6 points in odd pair family was not significantly different than that of pair family(1.07/6points).

The purpose of this study was to find out how much they have several aspects of food related knowledge and eating behaviors of high school students in Sungnam area. The self-administrated questionnaire was used. The result were as follows: 1. The average height of boys and girls was $172.6{\pm}0.7$ cm and $156.3{\pm}1.5$ cm respectively. The average weights of them were $62.4{\pm}0.5$ kg (male) and $47.2{\pm}0.8$ kg (female). BMI (Body Mass Index) of them were $20.74{\pm}0.14$ (male), $18.82{\pm}0.28$ (female). The average age is 16.7 years old. 2. The 66.5% of the subjects were spent more than one-third of their pocket money in buying on light meals during three times a week. There were significant differences between income level of family. Boys spent more money on each meal than girls. And significant differences were also obserbed by their residence area and Bundang residences spent more in buying snacks. 3. The rate of skipping meals was 51.2% in boys compared with 68.0% in girls. The frequencies of buying snacks instead of main meal were high in girls. Time limits in eating may possibly be the main reason for skipping meals (59.8%), especially in the morning. Skipping a breakfast becomes general eating habits in high school students, because of pressure for time to go to school. 4. It is required that parents should be taught to prepare balanced lunch box for their children because the rate of students who prepared two lunch boxes are 49.4%. 5. The students took snacks once or twice a day. They usually bought snacks in school concessions (51.8%) and they selected items of snack instinctivly. The girls ate snacks during lunch break time (31.7%) and after dinner (23.6%). Boys ate snacks after dinner (29.1%). Preference of foods were different by sex. Boys preferred bread (31.7%), milk and otherdairy products (80.8%), cola and soda (42.0%) as their snacks between meals. Girls selected biscuit, chip, beverage, coffee as their snacks, frequently. 6. BMI value of the group who ate between meals more than three times a day was lower $(18.78{\pm}0.65)$ than that of the group who ate nothing between meals $(20.71{\pm}3.79)$. 7. As for the nutritional knowledge, the students generally had higher correct rate of answer about which nutritive components of food has (76.6%). But they had lower knowledge on questions of nutritive values in food (10.6%). There was a meaningful relation between favorite food and nutritional knowledge. In conclusion, there were some problems on nutritional knowledge and eating habits among the high school students. Therefore, it was required that girls should be learned to recognize the importance of breakfast and needed to select balanced meals and snacks. And it was required that the nutrition education should be complemented to motivate and improve practical eating behaviors.
