BACKGROUND/OBJECTIVES: The intake of sugar has increased worldwide, and it is well established that childhood experiences and food preferences affect lifelong eating habits. To discourage sugar intake, nutrition education was imparted, and the effectiveness of the nutrition education program was investigated by considering the nutrient density and major dietary sources of sugar intake. SUBJECTS/METHODS: Twenty four-hour dietary recall and sugar intake frequency of 96 pre-school children (educated n = 47; non-educated n = 49) were collected on 3 consecutive days (1 weekend day, 2 weekdays) after 11 weeks of imparting nutrition education. Dietary intake of nutrients and total sugar were analyzed, and the intake frequency of sugar source foods were identified. All nutrition education programs were focused on a hands-on education program, and consisted of cooking lab, play, activity, animation, and visual materials. The difference between the two groups was verified by the Chi-square test or t-test. All statistical analysis was performed with significance level at P < 0.05. RESULTS: Compared to the non-educated group, the intakes of protein (P < 0.001), fiber (P < 0.01), potassium (P < 0.05), iron (P < 0.05), zinc (P < 0.05), and iodine (P < 0.001) were significantly higher, and the intakes of carbohydrate (P < 0.01) and total sugar (P < 0.05) were significantly lower in the educated group. The cumulative percent of sugar intake of top 20 sugar source foods in the educated group (82.80%) was lower than that of the non-educated group (85.75%). The contribution of beverages on total sugar intake was lower in the educated group. The average frequency of consuming sugary foods was significantly lower in the educated group (P < 0.05). CONCLUSIONS: Our results indicate that nutrition education on discouraging sugar intake is effective in reducing the amount of total sugar consumed, resulting higher nutrient density in the diets of pre-school children.

This study examined nutrient intake of long-lived men and women living in Jeollanam-do (Gangjin, Goksung, Gurye, Damyang, Boseong, Suncheon, Jangheung) which is known as representative Korean longevity area. Using the 24 hr recall method, dietary nutrient intake data were collected from 134 subjects (67 for 80~89 years old, 67 for more than 90 years old) in spring and fall 2012. Nutrient for each subject were calculated using CAN-pro. Subjects' daily mean intake levels of macronutrients, vitamins and minerals were higher in fall than in spring. Compared to KDRIs, subjects less than recommend (RNI/AI). East consumed nutrients compared to KDRIs were folate, potassium, calcium, vitamin $B_1$, vitamin $B_2$ and vitamin E. Subjects 232.8~363.1% of recommended intake level for natrium. The nutrient adequacy ratio (NAR) was 0.87 for subjects in their 80s and 0.79 for than 90 years old. The average NAR of all subjects was 0.83. The index of nutritional quality (INQ) exceeded 1 for most nutrients except for Ca (0.87), K (0.77), vitamin $B_1$ (0.84), vitamin $B_2$ (0.70) and folate (0.68). The average INQ was 1.31. This study concluded that even though long-lived men and women living in Jeollanam-do consumed less than RNIs, nutrition consumption quality was relatively fine based on NAR and INQ results.

This survey was carried out to Investigate the effects of dietary attitude on the nutrition knowledge, food habits, the daily average nutrient Intakes and the intake of Instant food, convenience food & fast food between college women and their mothers. Questionnaires were completed by 214 college nutrition majors and also by their mothers numbering at 173. College women's mothers showed a better average in meal time regularities per week than that of. college women. Also it is the fact that the college women had a higher frequency rate of instant food and fast food than their mothers. In the case of both college women and mothers if they eat at regular meal times they had a higher score in food habits. But the daily average nutrient intakes was not significant because of the fact that the meal time regularity and nutrient intakes 414 not concise. The higher frequency of instant food intake had a lower score in food habits and nutrition knowledge. The higher frequency of fast food Intake had a higher food habits score but it also had a lower score in nutrition knowledge. As in the intake of instant food and convenience food the college women had a higher Intake frequency. In the dietary pattern the college women they liked to eat (lour foods. But their mothers liked to eat Korean foods. The selective motive and the degree of satisfaction of food service industry product was for convenience and time saving. The food service industry products were found to be unsatisfactory in nutrition and sanitation. Therefore we must be more aware of preventing the disappearance of Korean traditional foods. For the continuing development of our dietary culture we need to have the food service industry to develop more suitable diet for Korean.

The Purposes of this study were to assess high school students' nutrient consumption at the ordinary time and to analyze nutrient contents and nutrition consumption of lunch. The questionnaires for self-reported food consumption were distributed to 210 students enrolled in a boy's high school and a girl's high school located in Seoul area. A final response rate was 87.1%, excluding responses that had significant missing data. Data of self-reported food consumption and BMI(Body Mass Index) were analyzed with descriptive analysis and t-test using SPSS Win(ver. 12.0). To measure the serving size and the waste amount, data were collected for three meals in a three day period at each school. A weighed plate method was employed to measure plate wastes and consumption of the menus served. Nutrient analyses for the served and consumed menus were performed using CAN-PRO. The result of nutrient intake determined by self-reported food consumption demonstrated 74.2% of boys and 70.0% of the girls did not meet EAR(Estimated Average Requirement) for calcium. In addition, the data collection showed that 60.2% boys and 26.7% girls did not consume EAR for Vitamin B$_1$. Nutrient analyses of the served and consumed menus at school lunch were compared with 1/3 of the Dietary Reference Intakes(DRIs) for this age group. The served menus did not meet 1/3 of the Recommended Intake(RI) for calcium, iron, and vitamin B$_2$. In contrast, the menu provided to students exceeded almost five times(490%) more than the sodium needed for 1/3 of the Adequate Intake(AI). Considering the amount of the students' plate waste, intake of vitamin A and vitamin C were below 1/3 of the RI, and calcium, iron, and vitamin B$_2$ intake were also reduced. Students' sodium consumption still exceeded 1/3 of the AI at 340.0%.

The daily food intake for dairy cows has to be effectively controlled to breed a sound group of cows as well as to enhance the productivity of the cows. But, feed stuffs are fed in the common bulk for a group of cows in most cases despite that the individual food intake has to be varied. To obtain the feed for each cow, both the nutrient requirements and the nutrient composition of fred have to be provided in advance, which are based on the status of cows such as weigh marginal weight amount of milk, fat concentration in milk, growth and milking stages, and rough feed ratio, etc. Then, the mixed ration fur diet would be computed by the nutrient requirements constraints. However, when TMR (Total Mixed Ration) is conventionally supplied for a group of cows, it is almost impossible to get an optimal feed mixed ration meeting the nutrient requirements of each individual cow since the constraints are usually conflicting and over-constrained although they are linear. Hence, addressed in this paper is a simulated annealing (SA) technique to find the food intake for dairy cows, considering the characteristics of individual or grouped cows. Appropriate parameters fur the successful working of SA are determined through preliminary experiments. The parameters include initial temperature, epoch length. cooling scheduling, and stopping criteria. In addition, a neighborhood solution generation method for the effective improvement of solutions is presented. Experimental results show that the final solution for the mixture of feed fits the rough feed ratio and some other nutrient requirements such as rough fiber, acid detergent fiber, and neutral detergent fiber, with 100 percent, while fulfilling net energy for lactating, metabolic energy, total digestible nutrients, crude protein, and undegraded intake protein within average five percent.

Sweeteners are beneficial for weaning pigs as they contribute to improved palatability, increased feed intake, energy provision, gut health support, and alleviation of post-weaning stress. This study was conducted to evaluate the effects of saccharin on growth performance, nutrient digestibility, fecal microbial, and fecal score of weaning pigs. A total of 80 (21 days old) crossbred ([Yorkshire × Duroc] × Landrace) healthy weaned piglets with an initial body weight (BW) of 6.85 ± 1.36 kg were randomly allotted to one of two nutritive treatments with 8 repetitions and five pigs (2 female and 3 male) per pen. The dietary treatments consisted of control (CON): basal diet; treatment (TRT): basal diet + 0.03% saccharin. The result showed that average daily gain (ADG) and average daily feed intake (ADFI) were increased (p < 0.05) in weaning fed saccharin supplemented diets compared with control diet. However, there was no significant difference in nutrient digestibility, fecal microbial, and fecal score among dietary treatments (p > 0.05). In summary, the sweetener supplementation with diet had a significant effect on ADG and ADFI without compromising nutrient digestibility, fecal microbial, and fecal score in the weaning pigs.

The purposes of this study were to investigate the effects of the popularity of menu items in nutrient consumption of school-aged children participating in a School Breakfast Program. The weighed plate waste method was used to determine the nutrient intake of students. The nutrient intake was evaluated based on the popularity of the menu item, gender, and grades. The average intakes of all nutrients except energy, fiber, and sodium were well within the goals. Actual nutrient intake varied based upon the popularity of $entr{\acute{e}}es$ and the popularity of menu items was a main effect in nutrient content of meals. When the most popular $entr{\acute{e}}es$ were served, school-aged children's energy intake and School Breakfast Program participation rate increased. Saturated fat and sodium intakes also were higher than the goal when the most popular $entr{\acute{e}}es$ were served. The significant main effect was grades for total fat (p < 0.05) and calcium (p < 0.05), which was qualified by the two-way interaction between gender and grades for saturated fat (p < 0.05), protein (p<0.1), iron (p<0.01), vitamin C (p<0.01) and carbohydrates (p<0.001). Gender itself was not a significant main effect. Based on the findings, the suggestions for educating school-aged children on more healthful breakfast food choices and reformulating recipes for the popular $entr{\acute{e}}es$ are made.

The purpose of this study was to investigate the dietary-intake and that of health by mean of questionarie and interview for male and female old persons living in Seoul area. The contents of study included general aspects, physical status and health, nutrient intake, and food intake frequency. The results from the above survey are summarized as follows ; 1. The age group in the range of 60 to 79 years old was 71%, and the average number of family was 4.9. The educational level was 56% of elderly persons were elementary or middle school graduates . 42.8% of elderly persons had an average monthly income of \490,000 to 300,000. 2. The aged average height, weight, and physical index were 164.9cm, 55.8kg and 20.4 in male, 152.7cm, 46.0kg and 20.3 in female which were lower than the Korean average standard. (male; 167.0cm, 61.0kg, female; 156.0cm, 55.0kg) In the degree of health self-consciousness, percentage distribution of poor and very poor was 29% in male, 59% in female. Among the condition of disease, neuralgia was 23.8%, hypertension was 17.2%, diabetes was 5.4%. 3. Average daily calorie intake was $63.9{\sim}70.4%$ for male and $76.4{\sim}83.9%$ for female which were lower than the Recommended Dietary Allowances for Koreans. Protein intake was $42.9{\sim}57.3g$ (which was $72.8{\sim}82.6%$ RDA) for elderly person, the proportion of animal protein to total protein intake were $24.3{\sim}28.2%$($12.9{\sim}16.2g$). Iron, Vitamin $B_1$, $B_2$ Niacin intake exceeded the RDA, but the intake of Calcium, Vitamin C were far less than that of RDA. 4. In the correlations between nutritional intakes and environmental factors and health, economic living situations and educational level as the factors which might influence the condition of nutritional intake was significant(P<0.01). 5. Food intake frequency of meats, fishes, eggs, for average of $1{\sim}2$ days per week were $44.8{\sim}50.5%$, that of milk and milk products for scarecely week were 42.9.% Correlation of food intake frequency was divided three levels-good, fair, poor. Food intake frequency as the factors which might influence the condition of nutritional intake was significant(P<0.01). The results of the survey reveal that many of elderly show evidence of general nutrient intake deficiency, it requires first of all importance of nutrition to improve nutritional level through to promotion of elderly health.

Accurate assessment of nutrient adequacy of a population should be based on usual intake distribution of that population. This study was conducted to adjust usual nutrient intake distributions of a single 24-hour recall in 2001 Korean National Health and Nutrition Surveys (KNHNS) in order to determine the magnitude of limitations inherent to a single 24-hour recall in assessing nutrient intakes of a population. Of 9,960 individuals who provided one 24-hour recall in 2001 KNHNS, 3,976 subjects provided an additional one-day 24-hour recall in 2002 Korean National Nutrition Survey by Season (KNNSS). To adjust for usual intake distribution, we estimated within-individual variations derived from 2001 KNHNS and 2002 KNNSS using the Iowa State University method. Nutritionally at risk population was assessed in reference to the Dietary Reference Intakes for Koreans (KDRIs). The Korean Estimated Average Requirement (Korean EAR) cut-point was applied to estimate the prevalence of inadequate nutrient intakes except for iron intakes, which were assessed using the probability approach. The estimated proportions below Korean EAR for calcium, riboflavin, and iron were 73%, 41%, and 24% from usual intake distribution and 70%, 51%, and 39% from one-day intake distribution, respectively. The estimated proportion of sodium intakes over the Intake Goal of 2,000 mg/day was 100% of the population after adjustment. The energy proportion from protein was within Korean Acceptable Macronutrient Distribution Ranges (Korean AMDR), whereas that of carbohydrate was higher than the upper limit and that of fat was below the lower limit in the subjects aged 30 years or older. According to these results, the prevalence of nutritional inadequacy and excess intake is over-estimated in Korea unless usual intake distributions are adjusted for one-day intakes of most nutrients.
