This study was carried out to investigate breakfast behaviors of female college students. 500 questionnaires were distributed and 417 were used for statistical analysis(SAS program). This survey was conducted from June, 2000 to October, 2000. 44.7% of the respondents considered lunch to be the most important meal. 51.6% students thought that people must eat breakfast. 41.6% of the students always eat breakfast but 22.1% do not eat breakfast. Conventional type of breakfast was found to be the most popular (67.6%). But ￦400,000 monthly allowance group(P<0.05) and self prepared breakfast group preferred Western style breakfast. The main reason for eating breakfast was for health(34.6%). The group of students with less monthly allowance were more likely to skip breakfast due to lack of time (p<0.01). Physical discomforts after skipping breakfast were: lack of strength(42.5%), stomach ache(36.3%), giddiness(9.1%), and recovered temper(12.1%). In conclusion, it is needed that a convenient and nutritional education should be developed for college students' health.

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 examined the hygiene practices of contract foodservice employees and investigated the influence of education and work environment on these hygienes practices. A questionnaire was distributed to 250 contract foodservice employees and a total of 232 responses were received and analyzed. The overall score for hygiene practices of contract foodservice employees was 3.89 based on a 5-point scale. Cross-contamination was prominent (highest score at 4.46) and the heating temperature was less prominent (lowest score at 3.49). The factors most affecting contract foodservice employees were their work period, the size of the contract foodservice management company, the number of meals served daily, the frequency of meal service per day and the frequency of hygiene education. Compared to small and medium-sized contract foodservice management companies, the major contract foodservice management companies showed higher scores for refrigerator/freezer control (P<0.001), vegetable/fruit disinfection (P<0.001), thawing (P<0.001), heating temperature (P<0.001), cleaning/disinfection (P<0.01), and personal hygiene (P<0.05). The frequency of hygiene education had a significant effect on the performance levels for refrigerator/freezer control (P<0.001), vegetable/fruit disinfection (P<0.001), thawing (P<0.001), heating temperature (P<0.001), cleaning/disinfection control (P<0.001), food supply control (P<0.05), and personal hygiene (P<0.05). From these results, to increase the sanitation quality of contract foodservice operations, hygiene practice levels need to increase and hygiene education systematically should be enforced for foodservice employees.

Objectives Meal and nutrition are important lifestyle factors that affect maintenance and promotion of health status and are also associated with chronic diseases. In Sasang constitutional medicine, dietary behavior according to the characteristics of Sasang constitution (SC) types is a key component in health management. The aim of this study was to evaluate the nutritional status and quality of meals according to the SC. Methods This was a cross-sectional study of 1,947 subjects surveyed in a community-based cohort called the Korean Medicine Daejeon Citizen Cohort study. Data were collected including demographic characteristics, Korea Sasang Constitutional Diagnostic Questionnaire, and nutrition quotient (NQ) for adults. We analyzed the differences in NQ grade and scores among three SC types: Taeeumin (TE), Soeumin (SE), and Soyangin (SY), by conducting chi-square and ANCOVA tests. Results The distribution of SC into TE, SE, and SY types was 43.1%, 25.2%, and 31.8%, respectively. The mean NQ score of all subjects was 53.4±8.6. There was a significant difference in the distribution of NQ grades and mean of NQ scores among SC types, including total and four sub-factors: balance, diversity, moderation, and dietary behavior. The TE type had the lowest score for the moderation factors in the crude model. The SE type showed lower NQ scores than the TE and SY types in all domains except moderation after adjusting for variables. Conclusions We found that dietary behaviors had to be distinct according to the SC types. These results elucidate why it is important to develop a customized dietary habit management program considering the SC types.

A study of eating behavior was conducted among 274 children of Nan Hyang elementary school, located in low income area of Seoul, where a school lunch program is not operated. During weekdays, 19.6% of children ate breakfast and 18.4% ate supper alone or with their siblings. The school provided boxed lunches for 10.5% of the children with governmental funds, who were chosen by the school based on their household income. But the percentage of the children skipping breakfast was 14.6%, lunch 10.3% and supper 8.0%. The results of nutritional analysis of the children who had three meals a day and those of children skipped one of the regular meals were compared. The group who had three meals consumed more nutrients except vitamin C than the group skipped meal (p<0.01). Most common meal pattern was consisted of cooked rice, Kimchi and side dishes. When the children didn't have afternoon classes, 10.0% of the children ate Ramen only at home without any side dishes. Among the protein sources, the beans and bean products were the most common items. When we studied the three different lunches such as A) the boxed lunches provided by school, B) the boxed lunches from home and C) the lunches ate at home, the A) lunches provided the most common items. When we studied the three different lunches such as A) the boxed lunches provided by school, B) the boxed lunches from home and C) the lunches ate at home, the A) lunches provided the milk products, fruits, ice cakes${\cdots}$etc. Their favorite foods were fruits, yoghurt, Chinese black noodle, and sweet potatoes whereas being not prefered foods, were aromatic vegetables. It seemed that the increasing rate of working mothers and the overflooding of instant foods have caused to neglect children's meal management. To solve these problems, nutrition education and extend of school lunch programs should be emphasized.

This study was to analyzed the quality of the meal and the level of nutritional intake in female college students according to the place of residence in female college students. This survey was conducted through questionnaire was given to 359 female students. The subjects were divided into two groups : one group was comprised of those the students who resided in a self-boarding house(SB group, n=245), and the other group comprised of was the student those who resided in the same house with their parents(HWP group, n=114). The mean age of the subjects were 21.6 years old(SB) and 20.6 years old(HWP)(p<0.05). The average height, weight and BMI were 161.8 cm, 57.9 kg, $20.3kg/m^2$ in the SB group and 161.9 cm, 53.4 kg, $20.3kg/m^2$ in HWP group, respectively. The SB group had significantly higher frequency of skipping breakfast and alcohol drinking consumption than the HWP group. There was no significant differences in the mean daily energy intakes between the SB and the HWP groups. However, the plant protein(p<0.01), carbohydrate (p<0.05), vitamin $B_1$(p<0.01), vitamin $B_2$(p<0.05), vitamin C(p<0.01), plant calcium(p<0.01) and potassium(p<0.05) intakes were significantly lower in the SB group were lower than the intakes in the HWP group significantly. And in addition, the cereals(p<0.05) and fruits(p<0.001) intakes in the SB group were significantly lower than the intakes in the HWP group. There was no significant differences in the KDDS and DVS between the two groups, but there was a decreasing trending downward. For that reason, the SB students seemed appeared to have more dietary problems than the HWP students. These results suggest that nutritional education for SB students are is needed in order to supply the lack of management capability on the proper help improve the diet of students living in independently life.

In Korea, changes in children's diet patterns accelerate their physical growth and development: frequent snacking has been presumed to be a major cause of increasing dental caries. The present study attempts to clarify the relationship between the physical development of growing children and their tooth decay. For this purpose, 632 six-grade children in 4 elementary school located in Urban(Seoul) and Rural(Po-gok, Yang-In) were classified into three groups based on the Weight Length Index(WLI), known to reflect the nutritional conditions of school-age children, and the relationship was analyzed between each group and the variables considered to be related with dental caries. The result is as follows: The average weight and height of the male is $44.88{\pm}10.89$ kg, $148.49{\pm}7.33$ cm and female is $43.35{\pm}9.60$ kg, $149.23{\pm}6.73$ cm, respectively, which are in the similar level with the Korean Physical Standard. The classification of the children by the WLI reveals a relatively high distribution of over-weighted child ren - 212 persons, 335% of the entire population. The DMFT Index was a little high in the rural area(3.15 teeth in urban and 3.31, in rural). Among the groups of children classified by the WLI, the over-weight group have the highest DMFT index(3.69 teeth). The relationship between the frequency of taking in basic nutrients and the DMFT index is also found: the relationship is not evident in case of the foods containing rich calcium, protein, as well as fruits and vegetables. But, in the protein-rich food, higher frequency of its intake means significantly lower DMFT index in the normal-weight group of the urban children. In case of carbohydrate, higher frequency of its intake means significantly higher DMFT index in all the groups of the rural children. The DMFT index has some correlations with the relevant variables: the index has a positive correlation with the frequency of snacking, and a negative correlation with the economic status. That is, the higher the frequency of snacking is, and the lower the economic status is, the higher the DMFT index may be. In the logistic multiple regression analysis conducted with the presence of DMFT as a dependent variable, only the frequency of tooth brushing is turned to be a variable affecting the presence of either decayed, missing, or filled teeth. Based on the above result, the variables affecting the DMFT index are a time spent on eating, frequency of intake of protein and carbohydrate for a week, frequency of snacking, regular dental check-ups, preventive behaviors for oral health(fluoride gargling, tooth brusing after each meal, proper tooth brushing method). These variables have a relationship with the DMFT index, but the degree is somewhat different between the groups classified either by the region or by the WLI. Therefore, appropriate nutrition management should be conducted according to the individual's nutritional conditions when the services like nutritional education are provided based on the closely-examined characteristics of each target group. And, at the same time, oral health education should be strengthened, and its importance should also be emphasized so that people can pay attention to their own oral health.

Nutrition during childhood is essential for growth and maintenance of health. Good food habits developed during the childhood will contribute both to the healthy growth and the prevention of the degenerative disease of later life. Both parents and the providers in child care centers play an important role for children's good eating behavior. Therefore all child care programs should achieve recommended standards for meeting children's nutritional and educational needs in a safe, sanitary, and supportive environment to promote the healthy growth and development of children. The purposes of this study were to evaluate the foodservice management practices and assess the needs for a Central Production Unit by contacting the child care center' providers. This approach was achieved using a variety of qualitative and quantitative information including the general foodservice management practices and the needs for a Central Production Unit. An indepth face-to-face interview with structured-questionnaires was undertaken at 32 representative child-care centers in Seoul. Statistical data analysis was done using the SAS program for descriptive analysis and ANOVA. The number of national/public and private sectors were 11 respectively, followed by 10 licensed home day-care centers. Total average number of children in child-care centers was 54.3 $\pm$48.5. The foodservice productivity index in child-care centers was 4.8 minutes per meal for public child care centers, 6.0 for private child-care centers, and 9.8 for home child care centers. Home child care centers were found to have the lowest productivity index which indicated inefficient foodservice practice. The important factors in group purchasing were menus(39.6%) or close distance(39.6%) > type of foodservice operation(32.8%) > total number of meals(19.9%) > food costs(16.2%) in order. Average score of the efficiency for central food production in child-care centers was 3.80 $\pm$0.84 out of 5.

This study was a qualitative investigation into hemodialysis patients' dietary practices. The purpose of this study was to explore the obstacles and requirements to maintain a recommended diet therapy in hemodialysis patients. Five patients undergoing hemodialysis in the renal chamber of the general hospital were interviewed individually. The interviews were based on an interview guide and analyzed by Giorgi's method of analysis. As a result of this study, five elemental factors and 12 subelemental factors were derived. Derived elements were "difficulty in dietary guidelines", "recognizing necessity of diet therapy", "awareness of importance of diet", "difficulty practicing diet therapy", and "looking for ways to practice diet therapy". Patients not only felt difficulties in practicing dietary guidelines but also recognized the need and importance of diet therapy. Patients seemed to have difficulty practicing meal therapy and eating with their families or others. They were also stressed by the limited selection of dietary components and rapid dietary changes before and after dialysis. However, patients showed a willingness to implement dietary management to improve their quality of life and to practice dietary therapy. In order to improve the practice of dietary management in hemodialysis patients, nutritional education should be focused on long-term dietary habits through continuous education and monitoring, not just one-off education. Moreover, patients should be educated that adherence to dietary control may be less burdensome on their families.
