Objective: The objective of this study was to investigate the effects of decreasing dietary crude protein content on rumen fermentation, mictobiota, and metabolites in goats. Methods: In an 84-day feeding trial, a total of twelve male Anhui white goat kids with initial body weight 15.9±1.13 kg were selected and randomly classified into two groups, feeding a normal crude protein diet (14.8% CP, NCP) or a low crude protein diet (12.0% CP, LCP). At the end of the experimental trial (on day 84), six animals were randomly selected from each group and were slaughtered to collect rumen fluid samples for the analysis of rumen fermentation parameters, microbiome, and metabolome. Results: The concentrations of ammonia-nitrogen, total volatile fatty acid, acetate, and propionate were decreased (p<0.05) in the LCP group in comparison with those in the NCP group. The abundances of genera Prevotella, Campylobacter, Synergistetes, and TG5, which were associated with nitrogen metabolism, were lower (p<0.05) in the LCP group compared with those in the NCP group. The levels of 78 metabolites (74 decreased, 4 increased) in the rumen fluid were altered (p<0.05) by the treatment. Most of the ruminal metabolites that showed decreased levels in the LCP group were substrates for microbial protein synthesis. Metabolic pathway analysis showed that vitamin B6 metabolism was significantly different (p<0.05) in rumen fluid between the two treatments. Conclusion: Decreased dietary protein level inhibited rumen fermentation through microbiome and metabolome shifts in goat kids. These results enhance our understanding of ruminal bacteria and metabolites of goat fed a low protein diet.

The objective was to evaluate the factors influencing on the growth of children aged 3 - 6 years by mini dietary assessment and anthropometric indices in 556 children and by analyzing mineral contents of hair from 273 children by inductively coupled plasma mass spectrometry (ICP-MS). The mean concentration of zinc (Zn) in hair was 68.9 $\pm$ 31.1 ppm and the zinc level of 91 ％ children was less than 60％ of the reference value of 180 ppm. The mean content of lead (Pb) in hair was 1.76 $\pm$ 1.20 ppm, but only 67％ of 273 children was within the reference value of 2 ppm and the lead level of 33％ of children was 2 - 4 times higher than the reference value. The level of Zn was negatively correlated with Pb content (r = -0.305, p 〈 0.01). Hair Zn content, regardless of age, was significantly positively correlated with height (r = 0.214) and body weight (r = 0.159). The height of 95.3％ children was belonged to the normal range of 90 - 109.9％ of standard value and the body weight of 49.8％ children was in the range of 90 - 109.9％ of standard value. However, 8.1 ％ children was overweighted (110 - 119.9％ of standard) and 9.4％ children was obese (120 - 149.9％ of standard) and 0.9％ children was severe obese (〉 150％) which resulted in total 10.3％ obese. Contrary to our expectation, 32.8％ children was underweight (70 - 89.9％ of standard) and 36％ of the underweight children showed the low content of zinc (10 - 49 ppm) in hair. There was no significant correlation between dietary intake of Zn and hair Zn content. Hair Zn content was low even though children consumed greater than 75％ of their requirement for zinc. Regardless of dietary intake of Zn, hair Zn level was rather negatively correlated to the content of Pb in hair. 38.8％ children had an unbalanced diet which resulted in lower intake of calorie, Ca, Zn, vitamin B$_2$ compared with those consuming variety of foods. Therefore, it would be needed that new approach for nutrition education to improve eating habit having the unbalanced diet in preschool children. It might be also suggested to develop new food products to complement the nutrients of Zn, Ca, Fe as snacks or dietary supplement for Korean preschool children.

I. Subject of the study A study on the nutritive value and utilization of powdered seaweeds. II. Purpose and Importance of the study A. In Korea the shortage of food will be inevitable by the rapidly growing population. It will be very important study to develop a new food from the seaweeds which were not used hitherto for human consumption. B. The several kinds of seaweeds have been used by man in Korea mainly as side-dishes. However, a properly powdered seaweed will enable itself to be a good supplement or mixture to certain cereal flours. C. By adding the powdered seaweed to any cereals which have long been staple foods in this country the two fold benefits; saving of cereals and change of dietary pattern, will be secured. III. Objects and scope of the study A. Objects of the study The objects will come under four items. 1. To develop a powdered seaweed as a new food from the seaweeds which have been not used for human consumption. 2. To evaluate the nutritional quality of the products the analysis for chemical composition and animal feeding experiment will be conducted. 3. Experimental cocking and accepability test will be conducted for the powdered products to evaluate the value as food stuff. 4. Sanitary test and also economical analysis will be conducted for the powdered products. B. Scope of the study 1. Production of seaweed powders Sargassum fulvellum growing in eastern coast and Sargassum patens C.A. in southern coast were used as the material for the powders. These algae, which have been not used for human consumption, were pulverized through the processes of washing, drying, pulverization, etc. 2. Nutritional experiments a. Chemical composition Proximate components (water, protein, fat, cellulose, sugar, ash, salt), minerals (calcium, phosphorus, iron, iodine), vitamins (A, $B_1,\;B_2$ niacin, C) and amino acids were analyzed for the seaweed powders. b. Animal feeding experiment Weaning 160 rats (80 male and 80 female rats) were used as experimental animals, dividing them into 16 groups, 10 rats each group. Each group was fed for 12 weeks on cereal diet (Wheat flour, rice powder, barley powder, potato powder, corn flour) with the supplementary levels of 5%, 10%, 15%, 20% and 30% of the seaweed powder. After the feeding the growth, feed efficiency ratio, protain efficiency ratio and ,organs weights were checked and urine analysis, feces analysis and serum analysis were also conducted. 3. Experimental cooking and acceptability test a. Several basic studies were conducted to find the characteristics of the seaweed powder. b. 17 kinds of Korean dishes and 9 kinds of foreign dishes were prepared with cereal flours (wheat, rice, barley, potato, corn) with the supplementary levels of 5%, 10%, 15%, 20% and 30% of the seaweed powder. c. Acceptability test for the dishes was conducted according to plank's Form. 4. Sanitary test The heavy metals (Cd, Pb, As, Hg) in the seaweed powders were determined. 5. Economical analysis The retail price of the seaweed powder was compared with those of other cereals in the market. And also economical analysis was made from the nutritional point of view, calculating the body weight gained in grams per unit price of each feeding diet. IV. Results of the study and the suggestion for application A. Chemical composition 1. There is no any big difference in proximate components between powders of Sargassum fulvellum in eastern coast and Sargassum patens C.A. in southern coast. Seasonal difference is also not significant. Higher levels of protein, cellulose, ash and salt were found in the powders compared with common cereal foods. 2. The levels of calcium (Ca) and iron (Fe) in the powders were significantly higher than common cereal foods and also rich in iodine (I). Existence of vitamin A and vitamin C in the Powders is different point from cereal foods. Vitamin $B_1\;and\;B_2$ are also relatively rich in the powders.'Vitamin A in ·Sargassum fulvellum is high and the levels of some minerals and vitamins are seemed4 to be some influenced by seasons. 3. In the amino acid composition methionine, isoleucine, Iysine and valine are limiting amino acids. The protein qualities of Sargassum fulvellum and Sargassum patens C.A. are seemed to be .almost same and generally ·good. Seasonal difference in amino acid composition was found. B. Animal feeding experiment 1. The best growth was found at.10% supplemental level of the seaweed Powder and lower growth rate was shown at 30% level. 2. It was shown that 15% supplemental level of the Seaweed powder seems to fulfil, to some extent the mineral requirement of the animals. 3. No any changes were found in organs development except that, in kidney, there found decreasing in weight by increasing the supplemental level of the seaweed powder. 4. There is no any significant changes in nitrogen retention, serum cholesterol, serum calcium and urinary calcium in each supplemental level of the seaweed powder. 5. In animal feeding experiment it was concluded that $5%{\sim}15%$ levels supplementation of the seaweed powder are possible. C. Experimental cooking and acceptability test 1. The seaweed powder showed to be utilized more excellently in foreign cookings than in Korean cookings. Higher supplemental level of seaweed was passible in foreign cookings. 2. Hae-Jo-Kang and Jeon-Byung were more excellent than Song-Pyun, wheat cake, Soo-Je-Bee and wheat noodle. Hae-Je-Kang was excellent in its quality even as high as 5% supplemental level. 3. The higher levels of supplementation were used the more sticky cooking products were obtained. Song-Pyun and wheat cake were palatable and lustrous in 2% supplementation level. 4. In drop cookie the higher levels of supplementation, the more crisp product was obtained, compared with other cookies. 5. Corn cake, thin rice gruel, rice gruel and potato Jeon-Byung were more excellent in their quality than potato Man-Doo and potato noodle. Corn cake, thin rice gruel and rice gruel were excellent even as high as 5% supplementation level. 6. In several cooking Porducts some seaweed-oder was perceived in case of 3% or more levels of supplementation. This may be much diminished by the use of proper condiments. D. Sanitary test It seems that there is no any heavy metals (Cd, Pb, As, Hg) problem in these seaweed Powders in case these Powders are used as supplements to any cereal flours E. Economical analysis The price of the seaweed powder is lower than those of other cereals and that may be more lowered when mass production of the seaweed powder is made in future. The supplement of the seaweed powder to any cereals is also economical with the criterion of animal growth rate. F. It is recommended that these seaweed powders should be developed and used as supplement to any cereal flours or used as other food material. By doing so, both saving of cereals and improvement of individual's nutrition will greatly be achieved. It is also recommended that the feeding experiment for men would be conducted in future.

To determine food preferences and nutrients intake of nursery school children, 199 children, ages 1 to 6 years, were assessed with a structured questionnaire completed by their mothers. The questionnaire included questions related to dietary habits, mother's interest in the child's health, family history of diseases, etc. The nutrients intake was measured by 24-hour recall method. Children's weight and height were measured by trained investigators on the same day. For analysis purposes, the subjects were grouped into underweight, normal and overweight groups based on the z-score of weight for height. Only 58.3% of the subjects were grouped into the normal weight group. On the other hand, 19.1% were in the underweight group and 22.6% were in the overweight group. Forty four percent of them showed unbalanced dietary habits such as preference for picky foods, 40.0% of them disliked vegetables, and 46.7% disliked minor grains other than rice. Children in the underweight group showed a higher score of inappropriate dietary habits compared to those of normal or obese groups. The level of nutrients intake of the subjects was higher than the Korean RDA value in general, except for Ca, calories, and Zn. However, 87.4% of the children showed a higher intake level than 125% of KRDA in protein, and 18.2% and 41.4% of them showed a lower intake level than 75% of KRDA in Fe and Ca, respectively. Children in the underweight group showed a higher percentage of eating less than 75% KRDA in niacin compared to those of the normal or overweight group (p<0.05) and we found a similar tendency in Fe, Zn and Vitamin $B_1$ intake.

The paper examines the effect of physical exercise on blood lipid with young male students. Our analysis is based on the body measurement, food intake and blood lipid component for 70 male students of Kongju National University who either major in physical exercise (group A) or do not major in physical exercise (group B). The average weight of group A is 71.97 $\pm$ 10.79 kg while that of group B is 67.57 $\pm$ 8.66 kg. The former is significantly higher (p<0.05) than the latter. The SBP of group A (128.20 $\pm$ 11.40 mmHg) is significantly (p<0.001) higher than that of group B (136.27 $\pm$ 13.18 mmHg). In terms of the intake of total kcal, group A marks significantly higher than group B; group A goes with 2190.26 $\pm$ 581.96 kcal and group B goes with 2392.94 $\pm$ 769.03 kcal. The comparative analysis of the three nutrient intake shows that the intake proportions for group A are carbohydrate 55.08 $\pm$ 6.03%, protein 15.58 $\pm$ 2.75%, and lipid 29.34 $\pm$ 5.16% while the intake proportions for group B are carbohydrate 57.29 $\pm$ 8.09%, protein 15.62 $\pm$ 3.26%, and lipid 27.10 $\pm$ 6.90%. For group A, the vitamin B$_1$ intake amounts to 1.50 $\pm$ 0.5 mg which fulfills 100% of RDA, and the niacin intake amounts to 16.57 $\pm$ 5.54 mg N.E which is less than RDA. In contrast, both intakes for group B are more than the RDA. In the case with minerals except calcium, both group A and B mark more intake than RDA. Group A's calcium intake is 517.12 $\pm$ 200.63 mg and group B's is 409.56 mg. The total cholesterol intake for group A is 447.00 $\pm$ 245.08 mg which is significantly (p<0.05) higher than for group B with 352.35 $\pm$ 200.25 mg. The total cholesterol in the lipid of serum is 151.30 $\pm$ 12.92 mg/dl for group A and 182.30 mg/dl for group B, where the dominance of group B over group A is true at the level of significance 0.01. In the case with triglyceride, group A is 107.57 $\pm$ 31.60 mg/dl and group B is 108.07 $\pm$ 33.93 mg/dl so that the group difference is non-significant. The HDL-cholesterol for group A is 54.67 $\pm$ 6.49 mg/dl which is significantly higher (p<0.001) than for group B with 36.13 $\pm$ 4.64 mg/dl. We conclude that regular exercise may have an effect on blood lipid metabolism among young males.

본 연구는 알코올중독자의 영양지식과 식습관 및 영양섭취상태의 특성을 알아보고, 영양교육이 이들 특성에 미치는 효과를 알아보고자 수행되었다. 알코올중독으로 병원에 입원한 37명 환자를 연구대상자로 하였으며, 이들의 영양지식과 식습관은 설문지를 이용하여 조사하였고, 영양교육은 80분짜리 5차시 분량의 프로그램을 제작해 실시하였다. 본 연구대상자는 40대 중반의 남성이었으며, 정상 체위를 지녔고, 병원에 입원하기 전 음주 빈도가 높고, 음주량이 많으며, 소주를 선호하는 음주습관을 지니고 있었다. 이들은 저 학력, 중 하류층 직업, 독거 비율이 높은 가족형태 등 사회경제적 수준이 열악한 편이었고, 자신의 건상상태에 대한 인식은 낮은 경향이었으며, 간 질환을 비롯한 질병 보유율이 높아, 삶의 질이 취약한 편이었다. 영양교육 실시 전 이들의 영양지식은 1점 만점에 0.52점으로 비교적 낮은 수준이었고, 식습관은 3점 만점에 1.70점으로 바람직하지 않은 경향이었다. 영양섭취상태도 에너지와 식이섬유를 비롯해 본 연구에서 조사한 8종의 비타민 중에 비타민 C, 티아민, 리보플라빈 및 엽산이 영양섭취기준을 충족하지 못했고, 6종의 무기질 중에서는 칼슘과 칼륨은 영양섭취기준에 미치지 못한 반면에 나트륨 섭취는 과다한 문제점을 보였다. 그러나 영양교육을 받은 후 본 연구대상자의 영양지식이 0.81점으로 유의하게 향상되었고, 식습관은 2.13점으로 유의성 있게 개선되었으며, 영양섭취상태도 다음과 같이 유의적으로 향상되었다. 즉 에너지, 탄수화물, 식이섬유, 비타민 E를 제외한 비타민 A, 비타민 C, 비타민 $B_6$, 티아민, 리보플라빈, 엽산 및 니아신, 칼슘, 인, 칼륨, 철분, 아연 모두 섭취가 증가했다. 반면에 나트륨 섭취는 감소했으나 여전히 목표섭취량의 256%에 달하였지만, 감소했으며, 이러한 결과 Na/K 섭취 비율이 저하되었다. 이와 같은 본 연구결과는, 비록 연구대상자가 광주광역시에 소재한 G병원에 입원 중인 소수의 성인남자 환자였다는 제한점은 있으나, 알코올중독 입원환자의 경우 영양지식 정도가 낮고, 식습관이 좋지 않으며, 영양섭취상태가 불량한 편이지만 이들에게 비교적 단기간의 영양교육을 실시함으로써 이러한 문제점들을 긍정적으로 변화시킬 수 있다는 점을 확인해 주었다. 그러므로 알코올중독전문병원 등 알코올중독자의 재활을 돕는 현장에서 영양교육의 필요성을 인식하고 영양교육을 적극 실시하여야 할 것으로 사료된다.

Dietary and other factors affecting bone density of 32 Korean healthy college women aged 19-23 years were assessed. Data for food and nutrient intake was obtained by a semiquantitiative food frequency questionnaire. Serum samples were anlayzed for total Ca, P, Ca++, PTH, calcitonin and 25-hydroxycholecalciferol , (25-OH-Vit D3) and BMDs of lumbar spine(L2-L4), femoral neck(FN), ward's triangle (WT) and trochanter(TR) were measured by an XR-series X-ray bone densitometer. Relationships between the factors and BMDs were analyzed by stepwise multiple regression analysis and Pearson's correlation coefficient(r). The results are summarized as follows. Mean daily intake of energy(86.1%), Ca(74.3%), vitamin A (53.75), Fe(49.75) and vitamin B$_2$(86.6%) were lower while other notrients incuding P(126%) were higher than the Korean RDA. The BMDs of lumbar spines and femurs ranged from 0.73g/$\textrm{cm}^2$ to 1.23g/$\textrm{cm}^2$and 0.48g/$\textrm{cm}^2$ to 1.04g/$\textrm{cm}^2$, respectively. Both protein and P intakes were inversely associated with serum total Ca. Furthermore, Ca intake as well as Ca/P ratio (Ca/P) were inversely associated with serum ionized Ca(Ca++) concentration. The intakes of protein P and Ca , however, were not significantly associated with the BMDs measured in this study. There were little association between BMDs and alcoholic beverage or caffeine consumption. The only significant association detected was a positive relationship between caffeine consumption and BMD of WT. It seemed to be noticeable that BMDs of L2-L$_4$, FN and WT were significantly inversely associated with serum P concentration. However, there was no significant association between BMDs and the levels of total Ca to Ca++ in serum. Body weight was positively associated with BMD of lumbar spine and BMI was also positively associated with BMDs of FN and WT. The subjects who had an early menarche appeared to have higher BMDs than those who had had a late mearche. According to stepwise multiple regression analysis. Menarche and BMI were stronger determinants of BMDs in the young women than was diet. P intake appeared to be a more potent dietary determinant than Ca intake. The three factors, menarche, BMI , and P intake , additionally accounted for 24% and 378% of the variance in BMDs of FN and L$_2$-L$_4$, respectively. Further investigation is necessary to determine the factors needed to increase serum P level which negatively affects. BMD in young Korean college women.
