This study was designed to identify how customers considered menu selection attributes on menu choice, and so the instrument for measuring that question was developed and menu selection behavior types were analyzed by customers' characteristics. Cronbach's alpha to assess the internal reliability of the developed scales was 0.8361, which indicated to be highly reliable. Construct validity was assessed by principal components factor analysis with a Varimax rotation to identify underlying dimensions of menu selection and then four factors explaining 55.618% of the total variance were found. These factors were labeled as 'quality of meals', 'attractiveness of meals', 'healthfulness of meals' and 'variety of meals', respectively. As a result of analysis on menu selection factors, 'quality of meals'(3.82 out of 5) was the highest consideration followed by 'variety of meals'(3.51), 'healthfulness of meals'(3.49) and 'attractiveness of meals'(3.34), so that menu marketing approaches in the perspective of quality of meals would do lead customers' selection rates, customer satisfaction and then sales highly. Frequent visitor selected menu indifferently but customers who were interested in food and menu highly, who perceived meals' quality highly, and who were satisfied with overall foodservice did with concern. On the basis of these results of study for the target of food court-style B ＆ I foodservice operation, which was introduced as an ideal model in future foodservice market by the concept of 'customer's selection right', the following study related with customers' meal patterns and perception of foodservice by menu selection attributes would be able to predict the chances for success of food court-style foodservice operations.

In the past few decades, great progress has been made on understanding the interaction between nutrition and health status. But despite this wealth of knowledge, health problems related to nutrition continue to increase. This leads us to postulate that the continuing trend may result from a lack of consideration for intra-individual biological variation on dietary responses. Precision nutrition utilizes personal information such as age, gender, lifestyle, diet intake, environmental exposure, genetic variants, microbiome, and epigenetics to provide better dietary advices and interventions. Recent technological advances in the artificial intelligence, big data analytics, cloud computing, and machine learning, have made it possible to process data on a scale and in ways that were previously impossible. A big data platform is built by collecting numerous parameters such as meal features, medical metadata, lifestyle variation, genome diversity and microbiome composition. Sophisticated techniques based on machine learning algorithm can be used to integrate and interpret multiple factors and provide dietary guidance at a personalized or stratified level. The development of a suitable machine learning algorithm would make it possible to suggest a personalized diet or functional food based on analysis of intra-individual metabolic variation. This novel precision nutrition might become one of the most exciting and promising approaches of improving health conditions, especially in the context of non-communicable disease prevention.

This study was done to determine the factors associated with childhood overweight in 721 sixth grade elementary school students, in Busan. The students' heights, weights, waist circumferences and triceps-skinfold thicknesses were measured using standard techniques. Other data were collected using a questionnaire that included information about physical activity, television watching, and the amount of exorcise taken during leisure times, family history of diseases related to obesity: social data including family income, parents'education and occupations, eating behaviors; parental weights and heights; and parental activity levels. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex. The prevalence of overweight revealed no significant difference between sexes, (24.2% in boys and 22.03% in girls). The risk of childhood overweight was significantly greater if either the mother or the father were overweight. The odds ratio for childhood overweight associated with maternal overweight was 5.045 (94% CI : 3.262-7.801), and 2.727 (95% CI : 1.764-4.218) was the case for parental overweight. Children having a history of hear diseases had higher odds ratios than those who did not. The odds ratios for overweight associated with income were not different. However, a higher odds ratio for overweight was observed in children whose fathers had only an elementary or middle school education than those whore fathers had a high school or college education. Children whose fathers' occupations were service workers or shopkeepers (OR : 3.314, 95% C = 1.851-5.934) or had no occupation (OR = 3.756, 95% CI : 1.898-7.430) had a treater risk of overweight than those whose fathers'were professionals or once workers. The risk of overweight increased in children having more irregular meal times and faster eating times, rather than those having an intake pattern of high energy and sugar containing floods. The amount of exercise taken during leisure times, and daily physical activity showed no difference between overweight and non-overweight children. However, television watching time, especially on weekends, was greater in overweight children than in non-overweight children. Television watching time was positively correlated with BMI, triceps-skin(31d thickness, waist circumference and waist/height ratio. Therefore, television watching was found to be a useful predictor of overweight in children. Television watching in children was negatively related to paternal activity levels, and positively related to parental television watching time. In fact, fathers whose children were overweight were physically less active than fathers whose children were non-overweight. Parents appeared to be a strong influence on their children's physical activity levels. In conclusion, a low family social class, defined on the basis of the father's occupation or education, parental overweight, increased television watching, and unhealthy physical activity levels in parents were all considered risk factors for childhood overweight. Among these, television watching time and lack of physical activity were considered to be the most important risk factors that could be easily modified for the prevention of and intervention in, overweight in children.

The objectives of this study were to assess food intake frequency and food behavior of infants and toddlers by using the Nutrition Quotient (NQ). A total of 368 subjects (infants 111, toddlers 257) in Ganghwa county were analyzed in this study. The NQ was examined using an NQ questionnaire, which consisted of 19 food behavior checklist items. The items were grouped into five categories: balance, diversity, moderation, regularity, and practice. All data were statistically analyzed by SPSS 20, and significant difference was evaluated by Student's t-test and $x^2-test$. The BMIs of infants and toddlers were $16.54kg/m^2$ and $16.01kg/m^2$, respectively. The frequencies of consumption of vegetables and fruits were higher (p<0.001) in girls and toddlers compared to boys and infants, respectively. Food behavior of meal regularity (p<0.001), breakfast eating (p<0.001), and chewing well (p<0.001) were also higher in toddlers compared to infants. Total NQ score of infants and toddlers were 62.05 and 64.91, respectively, which were within medium grade. The NQ score of toddlers was higher than that of infants (p<0.0.5). NQ score was positively correlated with parent's education, monthly income, age, and exercise. Therefore, children and their parents need proper nutrition education and counseling to correct their eating habits and improve their nutritional status.

This study aimed to evaluate dietary behaviors and food allergy status of preschool children in Gwangsan-gu, Gwangju Metropolitan city. The survey included 592 preschool children aged 1-5 years old in 31 childcare facilities. General characteristics, feeding type, complementary feeding, food allergy, dietary behaviors based on the NQ-P questionnaire, and dietary habits of their family were considered. Exclusively breast-fed children was 32.2% of the subjects and the breast feeding duration was 6.5 months. Subjects who had complementary feeding within 6 months was 77.2% and starting time of complementary feeding was 6.1 months. Fifteen percent of the subjects had food allergies and foods that induced allergy were instant foods, eggs, milk and dairy products, nuts, seafood. Food allergy was not related to breast feeding nor complementary feeding. The NQ-P score and its 3 factors including 'balance', 'moderation', and 'environment' were 59.9, 61.1, 56.0, 62.6, respectively. There were positive relations between children's dietary behaviors and family dietary habits such as breakfast eating frequency and meal regularity. As age of children increased, instant food intake increased and breakfast eating frequency decreased. Proper nutrition education is needed to children, their parents, and their care givers at childcare facilities to improve children's dietary behavior and health.
