In order to estimate the nutritive value of roasted full-fat soybean (FFS) in carp diet, growth performance and excretion of protein and phosphorus were examined using carps having mean body weight of 111 g. Growth trial was conducted for 4 weeks using the fishes fed 5 diets (Control, $F_{24}S_{13}$, $F_{16}S_{27}$, $F_8S_{40}$ and $F_0S_{56}$) containing 32%, 24%, 16%, 8% and 0% of fish meal (F) and 0%, 13%, 27%, 40% and 56% of full-fat soybean, respectively. A total of 800 fishes were allotted randomly by groups of 40 to 5 treatments with 4 replicates per treatment. Fishes were fed to station eight times daily. Feeding trial was conducted for 4 weeks. As dietary FFS increased from 0% to 56%, weight gain of fish decreased from 91 g to 39 g and feed conversion ratio increased from 1.06 to 1.95. Protein efficiency ratio (PER) was highest (2.35) in control group which had the highest protein intake, while PER significantly decreased with decrease in protein intake as dietary FFS level increased. Although dietary protein and energy levels were maintained constant, protein excretion per kg weight gain varied from 273 g to 579 g for the groups control and $F_0S_{56}$, respectively. However, the value for control group was not significantly different to those for the groups $F_{24}S_{13}$ and $F_{16}S_{27}$. On the other hand, the highest protein retention efficiency was found in group fed the diet $F_{24}S_{13}$. Fish fed the diet $F_8S_{40}$ excreted the lowest phosphorus (P) based on kg weight gain showing the highest P retention efficiency of 62%. P excretion per kg feed intake was in the range of 5 g to 10 g for the groups $F_8S_{40}$ and $F_{24}S_{13}$, respectively. The present results indicated that as dietary FFS level increased, growth performance and feed utilization decreased while excretion of protein and phosphorus increased. Therefore, it was concluded that more than 25% substitution by FFS for fish meal could exert negative effects on growth and feed utilization of carp.
This study investigated the nutritional status of 33 hemodialysis patients. Their weight, height, triceps and mid-arm circumference were measured and their dietary intake and blood profiles evaluated. The subjects were 57.1$\pm$11.9 years old. The energy intakes of men and women were 61% and 68% of RDA, respectively. The men and women's intake of protein was 0.93g/IBWkg/d and 0.99g/IBWkg/d, respectively. According to the distribution of BMI, 22.2% of the men and 73.3% of the women were underweight. A total of 5.6% of the men were overweight, versus none of the women. The serum albumin levels of the men and women were 3.56 and 3.52g/dl, respectively. The serum cholesterol levels of the men and women were 134.1 and 148.5mg/dl, respectively. The subjects were divided into three groups according to the level of albumin, and their intakes of nutrients were compared with one another. The group with high levels of albumin did not show higher energy and protein intake than the other groups but the serum total protein level was significantly higher. When the nutritional status of the patients was evaluated by weight and serum albumin level, 6.0% of them showed kwashiorkor-type malnutrition and 75.8% of them showed mild malnutrition.

This study was conducted to assess dietary intake and quality obtained by 24-hour recall method between Korean-Chinese in Yanbian, China(Korean-Chinese) and Koreans in Kuri, Korea(Koreans). The subjects consisted of 730 Korean-Chinese and 696 Koreans. Mean daily energy intake of Korean-Chinese was 1,788kcal and that of Korean was 1,844kcal. Proportions of energy intake from carbohydrate, fat, and protein were 62.6: 16.9: 14.2 for Korean-Chinese and 65.4: 16.3: 14.4 for Koreans. Nutrient intake levels of Koreans were higher than those of Korean-chinese in most nutrients. Calcium and vitamin $B_2$ intakes as percent of Korean RDA were less than 60% in Korean-Chinese. Koreans consumed calcium and vitamin A in the level less than 80% of Korean RDA. Iron intake level of Korean females was less than 75% of Korean RDA. Korean-Chinese consumed 90.4% of food from plant origin, and Koreans consumed 82.5% of food from plant origin. Mean dietary diversity score(DDS) of Korean-Chinese, $3.00{\pm}0.39$, was significantly lower than that of Koreans, $3.73{\pm}0.76(p<0.05)$. Mean dietary variety score(DVS) of Korean-Chinese, 13.6, was significantly lower than that of Koreans, 20.1(p<0.001). According to these results, some adults in the both Korean-Chinese and Koreans did not consume enough nutrients, especially calcium and vitamin $B_2$ intake for Korean-Chinese and calcium and vitamin A intake for Koreans. Dietary qualities of Korean-Chinese subjects and Korean females were not adequate. In the future, further research to promote dietary quality of Koreans including Korean-Chinese must consider the results of this study.
The purpose of present study was to assess the change of bone mineral density (BMD) by age and the dietary factors influcencing on BMD in Korean women in Taegu. The subjects were 242 healthy female in the range of 7-67 years old, and were divided into 4 age groups. BMD of lumbar of lumbar spine, femur(neck, ward's triangle, trochanter)and total body was measured by dual energy X-ray absorptionmetry. The nutrient intake measured by convenient method was similar to or more than the level of RDA. The significant relationship between nutrient intake and BMD was observed. Particularly for lumbar spine and total body in group 4 (50-60yr), such as energy, carbohyrate, protein, fat, Ca, animal Ca, meat Ca, Fe, thiamin and niacin were found significantly positive correlations. By analysis of multiple regression, significant relationships were shown between protein and lumbar spine and total body BMD in group 4, between ascorbic acid and total body BMD in group 2(17-34 yr). Energy expenditure showed better corrlations with BMD rather than nutrient intake. BMD was significantly greater in subjects consuming a mean dietary Ca intake more than 125% of RDA compared with less than 75% of RDA. In high Ca intake group ($\geq$125% of RDA), there were the significantly negative correlations between animal (meat) Ca and BMD in each bone of 7-9 years. The excessive intake of animal protein in this age group was found. And the correlations between BMD and past milk consumptin were significant in all skeletal sites of group 1(7-16 yr). This study confirms that the most effective way of preventing osteoporosis and the fractures is to maximize peak bone mass in early life and to minimize bone loss through the balanced adequate intake of Ca and other nutrients and regular physical activity.

Two trials were conducted to investigate the effect of decreasing the crude protein (CP) content of diets for finishing pigs containing two levels of available lysine on nutrient digestibility, nitrogen (N) balance and production performance. Ten finishing diets containing five levels of CP (on average 144, 155, 168, 182 and 193 g/kg fresh basis) and two levels of available lysine (6.9 and 8.2 g/kg fresh basis) were formulated. The diets were offered to pigs on a performance trial (n = 800 Large White (LW)${\times}$Landrace (LR) pigs) from 10 wk of age until finish at 21 wks+5 d of age. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were calculated. In addition, a digestibility/N balance trial was conducted using pigs (n = 80 $LW{\times}LR$) housed in metabolism crates. Digestibility of dry matter (DM), CP, oil, fibre and energy was determined. N balance values were determined through analysis of N content of urine and faeces ('as determined'). N balance values were also calculated using ADG values and assuming that 16% of growth is protein deposition ("as calculated"). Pig performance was poor between 10 and 13 wk of age which indicated that the dietary treatments were nutritionally inadequate for pigs less than 40 kg. There was a significant (p<0.01) quadratic effect of increasing CP level on feed intake, ADG and FCR from 10 to 13 wk which indicated that the lower CP levels did not supply adequate levels of essential or non-essential amino acids. There was no effect of increasing available lysine level throughout the early period, which in conjunction with the response in older pigs, suggested that both 8.2 and 6.9 g/kg available lysine were insufficient to drive optimum growth. There was a positive response (p<0.05) to increasing available lysine level from 13 wk to finish which indicated that 6.9 g/kg available lysine was not adequate for finishing pigs. Energy digestibility decreased with decreasing CP level of diets containing 6.9 g/kg available lysine which may be attributed to the higher fibre content of the lower CP diets. Nitrogen excretion (g/d) was lowered when dietary CP was reduced regardless of whether the values were determined through balance or calculated using ADG. Calculated N excretion decreased linearly (p<0.001) and quadratically (p<0.001) with decreasing dietary CP content. When the N balance figures calculated in this study were compared with those quoted in the Northern Ireland and English Nitrates Directive Action Programmes, N excretion was less per pig (wean to finish) offered a 169 g/kg CP, 8.2 g/kg available lysine diet (2.39 kg vs 3.41 kg (Northern Ireland) and 2.93 kg (England)).
Critically ill patients admitted in ICU and NCU were studied with respect to their nutritional status and support to them at initial period, and the effect of nutritional support after 3 weeks. The nutritional support was supplied to these patients with the enteral and parenteral nutrition. The results of biochemical test and status of nutritional support on 52(29 males, 23 females) critically ill patients were based on medical records and the anthropometry was measured on 28 patients. The subjects were in mild malnutrition. Their initial calorie intakes were 85% of BEE, 57% of total energy requirements and 49% of protein requirement were provided. Two groups, one group of serum albumin level more than 3.5g/dl and the other group of serum albumin level less than 3.5g/dl, were significant different in total calorie and protein intakes. After 3 weeks, inappropriate nutritional support in the group of normal nutrition results in significant decreasing of serum albumin level but, there were no changes in the group of malnutrition. Nutritional support is one of the mainstays in the management of these critically ill patients and is aimed at preventing malnutrition. Therefore, timely nutritional support is heavily required in cases of critically ill patients whether their initial nutritional status is normal or not.

The study evaluated the effects of dietary fiber and energy levels administered during two growing periods (d 0-28 and d 29-56) for pigs exposed to a high temperature. A total of 96 growing pigs were used in six treatments as: Two treatments in thermoneutral temperature (21℃-24℃) with dietary energy of 3,300 and the inclusion of high or low fiber, two treatments in heat stress (30℃-34℃) with dietary energy of 3,300 and the inclusion of high or low fiber, and two treatments in heat stress with dietary energy of 3,450 and the inclusion of high or low fiber. Among standard energy level treatments, heat-stressed pigs showed lower average daily gain (ADG), feed intake, digestibility of dry matter, gross energy, crude protein, and crude fiber in phases 1 and 2. Moreover, higher concentrations of acetate, propionate, butyrate, and total short-chain fatty acid (SCFA) in feces were shown in pigs fed high fiber diets. There was a negative interaction between dietary fiber and energy for the fecal concentration of isobutyrate in phase 1 and valerate in phase 2. Pigs in heat stress treatments showed a higher rectal temperature, respiratory rate, hair cortisol, plasma zonulin, and fecal lipocalin-2. Among heat stress treatments, the overall ADG was increased in pigs fed high fiber. Pigs fed high dietary fiber showed a greater concentration of acetate, propionate, butyrate, and total SCFA. High fiber treatments decreased plasma zonulin. In conclusion, the inclusion of beet pulp, soluble fiber, at the level of 4% looks necessary in pigs diet during heat stress.

In this study, we investigated the effects of feeding diets with different levels of energy and nutrient density on the egg quality of laying hens during the pre-peak and peak periods. A total of 192 (Hy-line brown) laying hens were used in a 15-week trial. The hens were randomly allotted to one of four treatments, each with four replicates (12 hens per replication). We assessed the effects of four level of dietary energy (2,710, 2,850, 2,870 and 2,890 kcal/kg) and three levels of nutrient density (Methionine + Cysteine: 0.56%, 0.85%, 0.80% and Crude Protein: 14.5%, 19%, 18%). Differences in the energy and nutrient density contents of diets showed no significant effect (P>0.05) on the average daily gain, average daily feed intake, feed conversion ratio, egg weight, or egg production of hens during the pre-peak and peak periods. However, hens subjected to 2,890 kcal/kg during the pre-peak period were found to lay eggs with significantly thicker shells, and yolk color was found to be significant enhanced in hens fed this diet during the pre-and peak periods. In contrast, we detected no significant effects of dietary energy or nutrient density on the Haugh unit or eggshell strength. In summary, increasing the energy level of diets from 2,710 to 2,890 kcal/kg was found to have positive effects on the shell thickness and yolk color of eggs produced by laying hens.
The bone mineral density(vertebrae Ll-4, femoral neck, Ward's triangle and trochanter) of 160 healthy adult women aged 29-45 was measured and general characteristics, anthropomentric measurements, and dietary intake were also studied to determine the main factors affecting the bone mineral density(BMD) of adult women. The nutrient intake of the subjects was adequate to RDA level except energy, Ca, Fe, and vit A. The BMD of vertebrae L24 showed significant positive association with nutrient intake such as animal protein, P, Ca(animal) and Fe(animal). The BMD of the femoral neck correlated significantly with anthropometric measurements such as height, weight, waist circumference, hip circumference, body fat and body mass index. The BMD of both sites(vertebrae L24 and femoral neck) were significantly related to vertebrae L24 was daily Ca intake and that of femoral neck was daily energy expenditure. In conclusion, adequate nutrient intake, especially protein, P, Ca and Fe as well as increases in physical activity were suggested to prevent the loss of bone mineral density in adult women.
This study was aimed at evaluating the lipid status of 122 pregnant women, who were attending peripheral community clinics in low-income areas and were vulnerable in terms of public health, by anthropometric measurements, estimating dietary intakes and analyzing serum lipids content and fatty acids composition. Regarding the skinfold thickness, it has increased more significantly in suprailliac than in triceps, biceps, subscapular, which means body fat has been accumulated in central parts more than in distal parts of the pregnants. It is found that intakes of energy, protein, lipid and carbohydrate are desirable while calcium, zinc and copper are low and sodium is excessive. Regarding dietary fat intake, the energy $\%$ of fat was within the same range as RDA(20%) for adults, but energy $\%$ intake from each fatty acid was usually low, especially energy % of monoun-saturated fatty acid intake was below RDA for adult women. And intake ratio of $\omega$6$\omega$3 fatty acids was desirable. Accordingly, it is thought that dietary fat intake was balanced in quality. Serum lipids concentrations were increased with the length of pregnancy and were higher as compared with non-pregnant women. Polyunsaturated fatty acids, especially $\omega$6 fatty acids, have gradually decreased with the length of pregnancy. Serum lipids content and fatty acids composition were not greatly influenced by dietary fat but serum free fatty acid level was negatively related to energy, carbohydrate, fatty acids and cholesterol intake. On the basis of the above results, it can be predicted that lipid metabolism for mother and fetus is changed by pregnant status and multilateral research on maternal nutrition in terms of areas and income levels will have to be made.
