Objective: The present experiment aimed to determine standardized ileal digestible (SID) lysine (Lys) requirements for pregnant sows individually housed under commercial farm conditions. Methods: Two hundred multiparous sows (parity = 5.1±2.0) on day 42 of gestation were randomly allocated to five dietary treatments with a balanced parity. Experimental diets were formulated to contain 0.22%, 0.32%, 0.42%, 0.52%, and 0.62% of SID Lys for the mid-gestation period (days 42 to 76) and 0.36%, 0.46%, 0.56%, 0.66%, and 0.76% of SID Lys for the late gestation period (days 77 to 103). All indispensable amino acids except Lys were provided at 110% of their requirement estimates. Daily feed allowance per sow was determined based on the back-fat thickness and body condition score at the second pregnancy check and on day 90 of gestation. Three different statistical models were used to estimate the SID Lys requirement. Results: Total born piglets alive per litter increased linearly and quadratically (p<0.001) as dietary SID Lys increased. For total born piglets alive per litter, the SID Lys requirement estimates ranged from 9.69 to 12.4 g/d for the mid-gestation period (1.19 to 1.52 g/Mcal metabolizable energy; 0.39% to 0.49%) and 14.6 to 17.4 g/d for the late gestation period (1.62 to 1.93 g/Mcal metabolizable energy; 0.52% to 0.62%). Conclusion: The mean values of the SID Lys requirement for the mid-gestation period and the late gestation period are 11.1 and 16.1 g/d (1.36 and 1.79 g/Mcal metabolizable energy; 0.44% and 0.58%), respectively, for maximal total born piglets alive per litter.

This study was conducted to assess blood components caused by metabolic syndrome increasing in postmenopausal elderly women. The blood samples of these subjects were analyzed to investigate the correlation of plasma taurine levels and plasma homocysteine levels, and serum lipid profiles. The subjects were 33 elderly women($72.8{\pm}4.4$ years). Their mean height, weight and BMI were $150.5{\pm}5.7\;cm$, $57.5{\pm}6.3\;kg$ and $25.4{\pm}2.5\;kg/m^2$. 16 women of this study subjects have been chronic diseases such as hypertension or diabetes. Their fasting blood glucose was $98.2{\pm}24.0\;mg/d{\ell}$, and their plasma total cholesterol (TC), HDL-C, LDL-C, triglyceride(TG) were $216.5{\pm}29.9$, $52.1{\pm}10.7$, $145.7{\pm}27.9$ and $141.2{\pm}59.6\;mg/d{\ell}$, respectively. Their blood lipid profiles were higher than the standard levels of metabolic syndrome, thus these levels of lipid profiles may play a role as risk factors on the elderly person. Plasma taurine level of the subjects was $278.5{\pm}48.1\;{\mu}mol/{\ell}$, and their plasma homocysteine level was $12.8{\pm}2.9\;{\mu}mol/{\ell}$. The concentration of plasma vitamin $B_{12}$ was significantly decreased by aging(p<0.05). The correlation of plasma homocysteine and plasma folate showed significantly negative(p<0.05). Thus, the decreased levels of plasma vitamin $B_{12}$ and folate by aging might affect on the plasma homocyteine concentration acting as a risk factor of cardiovascular diseases for elderly person. The correlation of plasma taurine and hemoglobin, and their platelet showed significantly positive(p<0.05). In conclusion, the diet on the elderly person is one of the important factors to prevent their health from chronic diseases. This study recommends that well balanced diets are needed for elderly person to keep their health and prevent from metabolic syndrome.

The purpose of this study was to compare dietary attitudes, dietary behaviors and diet qualities of Food and Nutrition major and non-major female student at a university located in Inchon. The subjects included 74 female Food and Nutrition and majors and 45 non-Food and Nutrition major female university students. This cross-sectional survey was conducted using a self-administered questionnaire, and the data were analyzed by a SPSS 10.0 program. The nutrient intake data collected from Three-day recalls were analysed by the Computer Aided Nutritional Analysis Program and then the diet quality was estimated using the Mean Adequacy Ratio (MAR), the Nutrient Adequacy patio (NAR) and the Index of Nutritional Quality (INQ). There was no significant difference in dietary behaviors between Food and Nutrition majors and non-majors. However, most of the female university students had poor eating habits, such as overeating, unbalanced meals, and skipping of meals. In particular, more than 50% of the female university students skipped breakfast. As for weighing themselves once a week, changing dietary lifestyles, calculating food calories and having interest in information on nutrition on health, the ratio of Food and Nutrition majors was significantly higher as compared to that of the non-majors. There was a significant difference in food consumption frequency except for mick and milk products, and iron-rich foods between the Food and Nutrition majors and non-majors. However, there was a significant difference in the frequency scores of iron-rich floods between the Food and Nutrition majors and non-majors. The MAR of Food and Nutrition majors and non-majors were 0.80$\pm$0.13, 0.79$\pm$0.13, respectively. However, in the Food and Nutrition majors and non-majors, the NARs of calcium were 0.61$\pm$0.21 and 0.59 $\pm$ 0.20, and that of iron were 0.61$\pm$0.21 and 0.59$\pm$0.16, respectively, which was extremely low when compared to that of the other nutrients. This result was similar to that of the INQ. Therefore, nutritional education is necessary if female university students are to practice optimal nutrition, including well-balanced diets and eating foods of high nutritional quality.

This study was carried out to investigate effects of crude protein (CP) levels in total mixed rations (TMR) on growth performance and meat quality in growing Korean black goats. Thirty-six 6-month-old growing black male goats (initial body weight =17.95${\pm}$0.13 kg) were used. The goats were randomly divided into four treatments and 9 animals were allotted to each treatment. In terms of treatments, CP levels in TMR were 14, 16, 18, and 20% of dry matter (DM) and all diets were isocaloric (2.4 Mcal ME/kg DM). The experiment lasted for 20 weeks with a 15-day adaptation period. After the end of the trial, five goats from each treatment were slaughtered to measure carcass characteristics and meat quality. Average daily gain (ADG) significantly (p<0.05) increased as dietary CP levels increased, but the highest ADG was found on the 18% CP treatment. The higher CP levels in TMR significantly (p<0.05) decreased feed conversion ratio, but the lowest ratio was on the 18% CP treatment, suggesting a higher bioavailability of nutrients by balanced energy and protein levels on this treatment. There was no significant difference in dressing percentage among treatments, but there was a tendency for levels more than 16% CP in TMR to have a comparatively higher dressing percentage than the 14% treatment. The percentages of meat, fat and bone were not significantly influenced by dietary CP levels. Dietary CP levels did not influence chemical composition of goat meat. Furthermore, there was no significant difference among treatments in any of the sensory parameters except for tenderness. Tenderness was similar for 18 and 20% treatments, which were significantly (p<0.05) higher than the 14% treatment. The results from this study suggested that an adequate CP level in TMR for achieving optimal growth performance and meat quality of growing Korean black goats might be 18% of DM, and that dietary CP level above 18% seemed not to further increase growth performance and meat quality.

4주간의 고지혈 유도식이를 섭취시킨 후 고지혈증 유도가 이루어진 실험 동물을 이용하여 생식 섭취로 인한 고지혈증 개선 효과를 확인하고자 하였다. 고지혈 유도가 확인된 실험 동물에게 고지혈사료에 30% 생식을 혼합한 식이를 투여하였을 경우 혈중 콜레스테롤량을 약 37% 정도 감소시킨 것으로 나타났으며, 간조직중의 콜레스테롤 역시 약 28% 감소한 것으로 나타나 생식의 섭취가 체내의 콜레스테롤 농도를 낮추어 주는 효과가 있는 것으로 확인되었다. 또한, 체내 콜레스테롤 구성에 있어서도 관상동맥 질환을 억제하는 것으로 알려진 HDL-C의 함량은 대조군에 대비하여 생식 섭취군이 약 28%정도 증가되었으며, 동맥벽에 축적되어 관상동맥질환 발병과 연관관계가 높은 것으로 알려진 LDL-C의 함량을 약 39%정도 감소시킨 것으로 나타나 체내 콜레스테롤 수치의 저하와 더불어 콜레스테롤의 구성 양상에도 이로운 점을 제공한 것으로 나타났다. 이러한 결과로부터 순환기계 질환 발병율을 나타내는 지표로 널리 이용되는 동맥경화지수와 심혈관위험지수를 산출한 결과 생식 섭취군은 대조군에 대비하여 동맥경화지수의 약 60%를 저하시켰으며, 심혈관위험지수 역시 약 56% 정도 저하시킨 것으로 나타났다. 이상의 결과를 종합하여 볼 때 생식 섭취는 체내 콜레스테롤의 농도를 저하시킴으로서 순환기계 질환의 위험도를 낮추는데 효과가 있는 것으로 생각된다.

This study compared the food habits and attitudes towards dietary life culture in types of feeding management, gender and grade. The subjects were 352 elementary school students who lived in Seocheon, Chungnam. The independently managed school students were better than jointly managed school students in food habits (p<0.05). In skipping school meals, upper grade students were skipped more than lower grade students (p<0.05). In rate of eating school meals, boys were faster than girls (p<0.001). The independently managed school students and the jointly managed school students were different on distasteful food. Boys disliked vegetables and girls disliked cereals and beans (p<0.05). Upper grade students ate more well-balanced meals than lower grade students (p<0.05). As for the question 'what you will do if the distasteful foods are provided through school meals', they responded. the highest percent of students, 'I will try once or twice'. And the response 'I have them for health' was higher independently in managed school students than the jointly managed school students (p<0.05), girls than boy (p<0.05), and the lower grades than the upper grades (p<0.05). As for the question 'what you will do if the distasteful foods are provided, after the guide for school meals was performed', the response, 'I will make an effort to have it' accounted for the highest percents, and there were differences in lower grade students who were high percents than upper grade students (p<0.01). As for the recognition for unbalanced diets, most of the students recognized that it is a 'bad habit'; the girl students accounted for more percentage than boys (p<0.05). The criterion of food choice were different in gender and grade (p<0.01). As for the factor of influences for the food habits formation, lower grade students were 'school education' and upper grade students were 'parents' (p<0.05). Thus, the systematic guide for proper intakes of nutrition should be performed. Also, the time when students can be educated by an expert of nutritional education, which is connected with school meals and students can grow healthily.

The purpose of this study was to investigate the fluid balance of the patients who were either on soft fluid diet or total parenteral nutrition. We studied 19 patients with neurologic disorders and 22 patients with oromaxillary surgery who were admitted to either D university hospital in Choognam or S general hospital in Seoul between May and November 1995. The mean age for the patients who had oromaxillary surgery was 24 years and their average hospital stay was 9 days. The mean age of the patients with neurologic disorders was 54 years and they were bedridden for average of 71 days. For the maxillary bone surgery patients we did not limit the range of their activities in the ward during data collection period. The patients with neurological disorders were bedridden and did not move around the ward. They were all either on soft fluid diet, or total parenteral nutrition. The findings of this study are as follows ; 1) The difference of the triceps skinfold thickness between the baseline and the final measurement was 0.4cm for neurologic patient group and 0.5cm for oromaxillary surgery patient group. The difference was not statistically significant in each group. 2) In the oromaxillary surgery patient group, the daily intake of fluid in the form of pure water, other beverages, fluid diet as well as IV fluid was 4581m1 while urine output was 2979ml. The difference between fluid intake and output was statistically significant, indicating that fluid intake was far more than urine output. In neurologic patient group, the daily intake of fluid including water from fluid diet and IV fluid was 2701m1 whereas urine output was 2253m1 and they were statistically significant. 3) For a more accurate assessment we adjusted the fluid balance based on weight changes during data collection period. In the oromaxillary surgery patient group. the difference between fluid intake and output was 1238m1 after weight changes being adjusted. The difference was statistically significant, suggesting fluid overload in this patient group. In neurologic patient group, the difference between fluid intake and output considering weight changes was 124ml. The difference was not statistically significant, suggesting that the fluid intake and output was well balanced in this patient group.
