Objective: The present study investigated the litter performance of multiparous sows fed 3% and 6% densified diets at farrowing to weaning during summer with mean maximum room temperature of $30.5^{\circ}C$. Methods: A total of 60 crossbred multiparous sows were allotted to one of three treatments based on body weight according to a completely randomized design. Three different nutrient levels based on NRC were applied as standard diet (ST; metabolizable energy, 3,300 kcal/kg), high nutrient level 1 (HE1; ST+3% higher energy and 16.59% protein) and high nutrient level 2 (HE2; ST+6% higher energy and 17.04% protein). Results: There was no variation in the body weight change. However, backfat thickness change tended to reduce in HE1 in comparison to ST treatment. Dietary treatments had no effects on feed intake, daily energy intake and weaning-to-estrus interval in lactating sows. Litter size, litter weight at weaning and average daily gain of piglets were significantly greater in sows in HE1 compared with ST, however, no difference was observed between HE2 and ST. Increasing the nutrient levels had no effects on the blood urea nitrogen, glucose, triglyceride, and creatinine at post-farrowing and weaning time. The concentration of follicle stimulating hormone, cortisol and insulin were not affected by dietary treatments either in post-farrowing or weaning time. The concentration of blood luteinizing hormone of sows in ST treatment was numerically less than sows in HE2 treatment at weaning. Milk and colostrum compositions such as protein, fat and lactose were not affected by the treatments. Conclusion: An energy level of 3,400 kcal/kg (14.23 MJ/kg) with 166 g/kg crude protein is suggested as the optimal level of dietary nutrients for heat stressed lactating sows with significant beneficial effects on litter size.

The purpose of this study was to propose the appropriate sizes and dish combination for nutritional-balanced lunch boxes delivered to children under the government-funded meal service program in Korea. The study was based on the 3 : 1 : 2 Meal Box Magic, a nutrition education method developed in Japan. A total of 290 lunch menus, comprising of 10 day menus from 29 organizations having delivered lunch boxes to children during summer vacation of 2008, were analyzed and used as the base data for lunch box combination. Dishes of the menus were classified into 6 groups: Rice group, Protein side dish group (including meat, fish, egg, and bean dishes), Vegetable side dish group, Kimchi group (including kimchi and jangajji), Soup stew group, and the other group. Nutrient analysis was conducted for 100 ml of these dishes by CAN Pro 3.0 utilizing volume and weight conversion data used for analysis of the Korea Health and Nutrition Examination Survey and those from the Nutrient Composition of Food for Consumers. All the possible combinations of 5 dishes, comprising of 3 dishes from Rice group, Protein side dish group, and Kimchi group, respectively, and 2 dishes from Vegetable side dish group, were made using the frequently served dishes from the respective dish group. Nutrient analysis of each combination was conducted based on the assumption that a lunch box was 600 ml and filled up to 80% by dishes using the volume ratio of 3 : 1 : 1.5 : 0.5 for Rice group : Protein side dish group : Vegetable side dish group : Kimchi group. The mean and standard deviation of energy and nutrients of all combinations calculated by weighting the serving frequency of each dish selected for the combinations were $621\pm81$ kcal for Energy, $22.1\pm5.0$ g for Protein, $120\pm45$ mg for Calcium, $4.1\pm1.1$ mg for Iron, $201\pm130\;{\mu}g$ RE for Vitamin A, $0.34\pm0.10$ mg for Thiamin, $0.27\pm0.10$ mg for Riboflavin, and $24.3\pm9.6$ mg for Vitamin C. The energy percentages from Carbohydrate, Protein and Fat were 66%, 14% and 20%. The analysis results met the nutrition standard of lunch boxes for male elementary students in grades 4 through 6 under the government-funded meal service program regarding calories, nutrients except calcium and riboflavin, and macronutrient distribution ranges. Accordingly appropriate box sizes were suggested for different age and sex groups to meet the respective nutrition standards. In addition, milk or dairy products were suggested to accompany lunch boxes to supplement calcium and riboflavin intake. The method of selecting box sizes and making dish combination suggested in this study could be useful for the organizations preparing lunch boxes under the government-funded children's meal service program where nutrition professionals are not available.

The adequate intake of energy and lysine for primiparous sows are necessary for maternal growth of sows and growth of their progeny. This study was conducted to evaluate the effects of dietary energy and lysine levels on primiparous sows and their progeny. A total of 48 gilts (Yorkshire × Landrace), with an initial body weight (BW) of 168.1 ± 9.71 kg and at day 35 of gestation, were allotted to eight treatment groups with a 2 × 4 factorial arrangement. The first factor was metabolizable energy levels in diet (3,265 or 3,365 kcal of ME/kg), and the second factor was lysine levels in diet (gestation 0.55%, 0.65%, 0.75%, 0.85%, lactation 0.70%, 0.85%, 1.00%, 1.15%). The BW gain (p = 0.07) and backfat thickness (p = 0.09) in the gestation period showed a tendency to be increased in sows fed the high-energy diets. In the lactation period, sows fed the high-energy diets tended to be greater BW (p = 0.09) and less BW loss (p = 0.05) than those of sows fed the low-energy diets. Sows fed high-energy diets had a tendency of greater piglet weight at day 21 of lactation and greater piglet weight gain (p = 0.08 and p = 0.08, respectively). Although the blood urea nitrogen (BUN) was increased linearly as dietary lysine level increased at day 110 of gestation (Linear, p = 0.03), the BUN was decreased linearly as dietary lysine level increase at day 21 of lactation (Linear, p < 0.01). In the composition of colostrum, sows fed high-energy diets had greater casein, protein, total solid, solid not fat, and free fatty acid concentrations than those of sows fed low-energy diets (p < 0.05). Supplementation of total lysine 0.75% for gestation and 1.00% for lactation with 3,365 kcal of ME/kg energy level could be applied to the primiparous sows' diet to improve performance of sows and growth of their progeny.

This research was designed to develop a computer program and evaluate the nutritional balances especially the balance of fatty acids, amino acids and antioxidant vitamins for convenience foods. The Korean convenience food, Kimbab purchased from markets was evaluated by using the self-developed computer program. Contents of calories, protein and calcium were lower$(1/3^{\circ}{\neq}1/2)$ than the recommended levels of Korean adult woman, and the carbohydrate/ protein/ fat(CPF) energy ratio was 70: 13: 17. The mean P/ M/ S ratio was 2.2/ 1.4/ 1 and that of ${\omega}6/\;{\omega}3$ fatty acids was 17.9/ 1, which was higher than the desirable ratio of $4{\sim}8/\;1$. Average essential amino acid balance of market-Kimbab samples was within the desirable range even though the absolute amount of protein was lower than the recommended level. Contents of antioxidant vitamins (A, C &E) were lower than recommended levels. Two kinds of nutritionally adjusted Kimbab menu were established by self-developed computer program. Some of major changes was adding food ingredients such as tuna fish and perilla leaf cooked with sesame oil and soybean oil to increase ${\omega}3$ series fatty acids. Some fruits and milk were also added to the menu. The adjusted CPF ratios was 63: 15: 22 and the new values for P/ M/ S and ${\omega}6/\;{\omega}3$ fatty acids ratios were 1.0/ 1.2/ 1/0 and 6.1/ 1 respectively. In sensory evaluation of two kinds of adjusted Kimbab, the taste and overall estimation scores were higher than unadjusted Kimbab. The computer program developed in this study might be used as a tool for the evaluation of nutritional balance of other convenience foods and menu planning.

The purpose of this study was to examine the comparison of growth development, bone mineral density and nutrient intakes between double income families' preschool children(DIFPC) and full-time housewives' preschool children(FHPC). Subjects were 111 preschool children. Anthropometric characteristics and bone mineral density in right forearm were measured. The questionnaire was composed of health status, life style, dietary behaviors, and dietary intakes and was completed by the children's mothers. The average age of the DIFPC(n=60) was 53.02 months and that of the FHPC(n=51) was 54.80 months. The birth height and weight of the subjects were 50.47㎝ and 3.27㎏ for DIFPC and 50.85㎝ and 3.36㎏ for FHPC, respectively. The average height, weight, % body fat, and obesity index were 108.50㎝, 18.35㎏, 15.35%, 96.71% in DIFPC and 111.46㎝, 19.64㎏, 16.80%, 97.31% in FHPC, respectively. The bone mineral density in forearm of two groups were 0.24g/㎠ in all. The infant feeding method was significantly different between DIFPC and FHPC; 58.9% of DIFPC was fed formula, while 44.4% of FHPC was fed breast milk(p<0.05). Proportions of children for their regular meal were 59.4%, 89.6%, and 61.0% for breakfast, lunch, and dinner, respectively. The major reasons for irregular meal were lack of time and poor appetite for breakfast and snacks for lunch and dinner. Most of the children answered they have snack over once a day, and 60.0% have unbalanced diet. The intakes of energy, calcium, iron, zinc, vitamin A, vitamin B1, niacin, and vitamin C did not meet the Korean RDAs. The intakes of K and vitamin A for DIFPC were significantly higher than those of FHPC(p<0.05, p<0.05). In conclusion, double income families' preschool children more have a low frequency of breast feeding and low intakes of micro nutrients, such as K and vitamin A than full-time housewives' ones.

This study was performed to compare nutrient intakes, diet quality and serum indices (TG, Total cholesterol, LDL-cholesterol, HDL-cholesterol, RBC, Hb, Hct, Serum iron, ferritin, MCV) of obese and normal weight children. The subjects were 149 children living in the Seoul and Gyeonggi areas. Each subject was assigned to one of such as normal weight group ($15th{\le}BMI$ percentile < 85th, n = 82) or obese children ($85th{\le}BMI$ percentile, n = 67) according to their percentile of BMI by The Korean Pediatric Society. Data on dietary intakes, body composition and serum indices were obtained. Differences of all the above variables were assessed. Energy, carbohydrate, fat, cholesterol, total fatty acid, SFA, MUFA, PUFA, phosphate, potassium, zinc, vitamin $B_1$ and vitamin $B_6$ intakes of girls in the obese group were higher than those of the normal weight group (p<0.05). The intake of fiber was as insufficient as below 50% of KDRIs in both groups. Nutrient adequacy ratio of calcium, iron, phosphate, zinc and folate in obese boys were lower than those of normal weight boys (p<0.05). Energy intakes of grain and milk and dairy food in the obese girl group ($905.9{\pm}344.5kcal,\;210.9{\pm}166.4kcal$) were higher than those of normal weight girls ($671.2{\pm}360.7kcal,\;184.0{\pm}103.5kcal$) (p<0.05). HDL-cholesterol level of obese boys ($52.7{\pm}6.3mg/dL$) was significantly lower than that of normal weight boys ($65.3{\pm}15.6mg/dL$). Serum iron level of obese boys and girls (boys: $79.4{\pm}32.6mg/dL$, girls: $98.3{\pm}16.2mg/dL$) was significantly lower than those of normal weight children (boys: $104.8{\pm}38.6mg/dL$, girls: $106.7{\pm}28.9mg/dL$) (p<0.05). These results suggest that there should be sensible food selection and more intakes of fruit and vegetable are needed to improve the nutritional status in obese children.

This study compared the college students' dietary behavior for processed foods, who will be the main consumers in the future and looked for the measures to understand and establish the right food labeling system by surveying the level of understanding and utilization of food labeling. The data was analysed by SPSS win 17.0 program, and the results are as follows. For the standard of selecting processed foods, the group with high nutrition knowledge considered the reliability of foods as important and the group with low nutrition knowledge considered the products introduced in TV commercial as important. When purchasing processed foods, the group with high nutrition knowledge considered nutrition, taste, price, appearance(shape), and the consumable period more than the group with low nutrition knowledge. For trans fat, the group with high nutrition knowledge learned more about it than the group with low nutrition knowledge. The ratio of confirming food nutrition label was higher in the group with high nutrition knowledge. Regarding the level of confirming individual food labels, the highest level was for milk and dairy products. And there was significant difference for the processed products of meat, cookies, bread and noodles. It was found that the level of confirmation was higher in the group with high nutrition knowledge. And the most important indication for individual food product was the consumable period. To preserve the purchased foods, the group with high nutrition knowledge preserve the foods in line with the description written on the food cover sheet, and this group used to return or exchange the products when they found them spoiled or purchased by mistake. The group with high nutrition knowledge knew more about the nutrition indication than the group with low nutrition knowledge. The necessity of nutrition indication for processed foods and the need of education and PR(Public Relation) were acknowledged higher in the group with high nutrition knowledge. For the effect of nutrition indication, it showed that the group with high nutrition knowledge thought it would improve the quality and the group with low nutrition knowledge thought it would be helpful when comparing the product with others. The group with high nutrition knowledge showed higher understanding level about nutrition indication than the group with low nutrition knowledge.
