This study conducted with 268 female elderly who visited welfare center and senior citizen center in Changwon city to identify the dietary status according to social frailty stage using nutrition quotient for elderly (NQ-E). As a result of the survey, 75.0% of the elderly had no nutrition education. The elderly in social frailty stage was 43.7%, pre-frail was 35.1%, and robust was 21.2%. The scores of NQ-E (61.65), balance (47.78), moderation (86.18), and dietary behavior (55.23) were within the medium-high grade, while diversity (48.37) was within the medium-low grade. Among the balance factor item, there was a significant difference only in the frequency of fruit intake according to social frailty stage (p<0.05). Among the diversity factor item, there were significant differences in vegetable intake (p<0.05) and the rate of eating alone (p<0.001) according to social frailty stage. Among the dietary behavior factor item, there were significant differences in whether to strive for a healthy diet (p<0.05), exercise time and depression (p<0.001), and subjective recognition rate of health (p<0.01) according to social frailty stage. Based on these results, education focusing on various food intake is needed, and continuous support from the government and local governments is needed to connect the social support network of the elderly and support programs to prevent them from going to social frailty stage.

This study was performed to assess diet qualities by sexes and ages of adults over thirty years old in Jeon-ju area. Diet survey with one day 24-recall method was used done for 382 subjects(129 males & 253 females). Survey sample was divided into six groups by sex and age groups: male 30-49, male 50-64, male 50-64, male 65-79, female 30-49, female 50-64 and female 65-79 years. Diet quality was assessed by NAR(Nutrient Adequacy Ratio), MAR(Mean Adequacy Ratio), INQ(Index of nutrition quality), KDDS(Koreans Dietary Diversity Score), Meal Balance, DVS(Dietary Variety Score), DQI(Diet Quality Index). The 5-point DQI assessed the important dietary guidelines for Koreans. The averages of energy, protein, P, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than 70% of RDA. The averages intakes of Ca and vitamin A were very lower than RDA all groups. The averages of MAR were 0.78, 0.81, 0.83 in male 30-49, 50-64, 64-79 years, 0.73, 0.77, 0.71 and in female 30-49, 50-64, 65-79 years, respectively. The averages of MAR in female 30-49 years and female 65-79 years were significantly lower than the averages MAR of male 65-79 years. The averages of Sugars and Beverages intakes were significantly higher in male 30-49 years than others. Animal food intake ratio(% total food intake) in the male 65-79 years(16%) was significantly higher than male 30-49 years(11%). The averages of Nutrition intakes were higher in male compared to female. The subjects who consumed all of the major five food groups were 5% in male 30-49, 17.8% in male 50-64, 25.0% in male 65-79 years, 18.9% in female 30-49, 23.7% in female 50-64, 11.5% in female 65-79 years. The averages of KDDS were 3.5, 3.9, 3.9, 3.8, 3.8, 3.5, respectively. The averages of Meal Balance were 8.6, 9.1, 9.1, 8.3, 8.4, 7.8, respectively. The averages of DVS 20.1, 19.9, 19.9, 20.5, 19.0, 17.2, respectively. The averages of DQI were 1.7, 2.2, 2.1, 2.0, 2.1, 1.7, respectively. 81.8% of the subjects had KDDS scores of 2 to 4 and 87.3% of the subjects has Meal Balance scores 4 to 10. In contrast, 89.8% of the subjects had DQI scores of 0 to 3. In view of these facts there are few who observed the five dietary guidelines for Koreans. There findings suggest that dietary qualities were associated with nutrient intake the relation factors may vary by sex and age of adults over thirty years old in Jeon-ju area. Common problems were lack of Ca, vitamin A and dairy products intakes. Therefore adults over thirty years old in Jeon-ju area need the important nutrient management such as Ca, vitamin A.

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.

This study was designed to determine the effects of protein sources on the curation of gastric ulceration, protein metabolism, and nitrogen balance in rats with gastric ulcer induce by restraint and water immersion stress. After the rats were fed 10% casein diet for 3 weeks, four groups of the rats were forced in 5$\times$5$\times$15cm plexiglass cage. The restraint and water immersion stress was carried at 20$\pm$2$^{\circ}C$ for 8-hour. The other one group(control group) was not exposed to stress. After stress 4 kinds of different diets containing 20% protein were given for 5 days. The protein sources were casein, whey protein, soy protein, gluten. The control group was fed to 10% casein diet. The results were as follows ; the weights of rats were not different among the diet groups During the experiment period follows ; the weights of rats were not different among the diet groups during the experiment period (for 5 days). The ulcer index of rats fed 10% gluten and soy protein diet was significantly higher than those of casein and whey protein diet groups(p<0.05). The level of serum albumin was not significantly different among diet groups. But hematocrit and the level of $\alpha$-amino-N, BU and UUN of plant protein diet groups were higher than animal diet groups, the urinary hydroxyproline of soy protein group was the highest and the whey protein was the lowest. The digestibility and BV of nitrogen of gluten diet group were significantly higher than those of casein and whey protein diet groups(p<0.05). The animal proteins had more curative effects of ulcer than plant animals. The results of this study provide useful information concerning diet therapy for the patients with gastrointestinal diseases and the field of enteral diet materials.

The effects of different dietary electrolyte balance (DEB) on growth performance, nitrogen (N) metabolism and some blood biochemical parameters were investigated in 2 to 3 months old growing rabbits. A total of 150 growing rabbits of 2 months age were randomly divided into five groups according to average body weight, with 30 rabbits in each group. The DEB levels of the five experimental diets were -154, -3.16, +201, +347, and +500 meq/kg of dry matter (DM), respectively. There was a 7-d adaptation period and a 23-d experimental period. The results showed that the DEB levels had a quadratic affect on the average daily feed intake (ADFI) (p<0.001). The greatest ADFI was achieved when the DEB level was +201 meq/kg DM. Fecal N (FN) content linearly decreased (0.047), while digestible N (DN), retained N (RN), efficiency of intake N converted into digestible N (DN/IN) and the efficiency of intake N converted into retained N (RN/IN) linearly increased with the DEB increase (0.020, 0.004, 0.021, and 0.049, respectively). Serum phosphorus (P) ion content linearly increased with the DEB increase (p = 0.036). The DEB had a quadratic relationship with serum anion gap (AG) (p = 0.002) and serum parathyroid hormone (PTH) content (p = 0.016). The DEB levels quadratically affected base excess (BE) in the plasma (p<0.001). In conclusion, the DEB unaffected growth performance but affected feed intake, N metabolism and some blood biochemical parameters of growing rabbits.

Objectives: This study was conducted to investigate the associations between obesity and the children's Nutrition Quotient (NQ) and to further examine the relationships between NQ and mini dietary assessment (MDA) of their parents. Methods: The subjects were 355 children aged 3 to 5 years and their parents in Dongducheon. We collected parental-reported NQ questionnaires for children and MDA of parents. Anthropometric measurements, height, weight and BMI by BIA were measured in children. Overweight and obesity were determined according to age- and sex-specific BMI percentile from the 2007 Korean national growth chart. Statistical analyses consisted of the chi-squared test, ANOVA, partial correlations and logistic regression analysis adjustments for parents BMI. Results: Approximately 20.8% of preschool children were classified as overweight or obese. Underweight children showed a significantly higher score for balance than overweight children. The NQ of the children was $61.9{\pm}11.6$, and NQ scores and their parents' MDA did not exhibit any significant differences according to degree of obesity. After adjusting for parent's BMI, children's BMI was significantly correlated with balance and moderation among NQ factors. Parent's MDA showed significant correlation with their children's NQ, balance, diversity, moderation, regularity, practice and NQ grade, except for diversity of father. Additionally, NQ grade had a significantly increased (150.1%) odds ratio (OR) of being overweight (95% CI 1.008-2.234). Conclusions: These results show that NQ for children is influenced by their parents' MDA and BMI. Furthermore, our findings support the association between overweight prevention and improvement of NQ grade among preschool children.

Objective: This trial was performed to examine the effects of ruminally degradable starch (RDS) levels in total mixed ration (TMR) with low corn-based starch on the milk production, whole-tract nutrient digestibility and nitrogen balance in dairy cows. Methods: Eight multiparous Holstein cows (body weight [BW]: $717{\pm}63kg$; days in milk [DIM]: $169{\pm}29$) were assigned to a crossover design with two dietary treatments: a diet containing 62.3% ruminally degradable starch (% of total starch, low RDS) or 72.1% ruminally degradable starch (% of total starch, high RDS). Changes to the ruminally degradable levels were conducted by using either finely ground corn or steam-flaked corn as the starch component. Results: The results showed that dry matter intake, milk yield and composition in dairy cows were not affected by dietary treatments. The concentration of milk urea nitrogen was lower for cows fed high RDS TMR than low RDS TMR. The whole-tract apparent digestibility of neutral detergent fiber, acid detergent fiber and crude protein decreased, and that of starch increased for cows fed high RDS TMR over those fed low RDS TMR, with no dietary effect on the whole-tract apparent digestibility of dry matter and organic matter. The proportion of urinary N excretion in N intake was lower and that of fecal N excretion in N intake was higher for cows fed high RDS TMR than those fed low RDS TMR. The N secretion in milk and the retention of N were not influenced by the dietary treatments. Total purine derivative was similar in cows fed high RDS TMR and low RDS TMR. Consequently, estimated microbial N flow to the duodenum was similar in cows fed high RDS TMR and low RDS TMR. Conclusion: Results of this study show that ruminally degradable starch levels can influence whole-tract nutrient digestibility and nitrogen balance in dairy cows fed low corn-based starch diets, with no influence on performance.

People usually try to take in nutrition component which is necessary for physical growth, developing and maintaining the health through usually balanced dietary life. However in looking over the results of recent national nutrition survey, even if the nation’s average taking in nutrition condition is fairly good, considering the individual cases there has happened a problem about the balance of taking in nutrition due to the wrong dietary life.
