We made a survey of the pattern of dietary life, the taste and the intake-frequency for Kwamaegi in Kyungbuk province. And the results were summarized as follows : 1. Flavor(65.2%), nutritive value(14.6%), cleanliness(14.3%), price(4.3%) and calorie(0.7%) were considered to select food in that order. 2. The younger, the more they preferred foreign food to Korean food and the older, the more they preferred Korea food to foreign food. 3. Most of people(91.4%) answered positively to Kwamaegi and had a high preference of Kwamaegi. On most occasions, they were inclined to eat Kwamaegi as the side-dish(71.1%) served with drink. 4. Most of men(61.1%) have eaten 3∼10 Kwamaegis at a table, but most of women(53.7%) have eaten 1∼2 Kwamaegis at a table.

The purpose of this study was to determine the optimal mixing ratio of Agaricus blazei Murill powder and butter in the preparation of cookies. The experimental design utilized herein was based on central composite design for response surface methodology, which included 10 experimental points, including 2 replicates for Agaricus blazei Murill and butter. The physical, mechanical, and sensory properties of the test were measured, and these values were applied to the mathematical models. A canonical form and perturbation plot showed the influence of each ingredient on the final mixed product. The spread ratio increased significantly with an increase in Agaricus blazei Murill powder and butter (p<0.05). The response surface methodology was applied to evaluate the effect of Agaricus blazei Murill powder and butter on cookie moisture and color (L, a) (p<0.001). Sensory evaluation showed significant values for color (p<0.05), flavor (p<0.05), texture (p<0.05) and overall quality (p<0.01) in the predicted model. The optimum formulation by numerical and graphical methods was calculated as follows: Agaricus blazei Murill powder 3.63 g, butter 55.37 g.

We measured volume of daily urinary excretion. daily excretion of $Na^+$ and $K^+$, creatinine clearance, blood $Na^+$ and $K^+$ concentration on 34 subjects(12 men. 21 wenen) who live in Hanlim sub-county. Kimhae county. Kyongnam, Korea in December 1990. The data were compared to the data in 9 urban residents(4 men, 5 wemen). Results were as follows. I) Daily mean urinary $Na^+$ excretion of rural residents was $255{\pm}95.6$mEq/day. It is much lower than that of in 1960 but higher than that of students living in urban area(1975) or that of occidentals. 2) Daily mean urinary $K^+$ excretion of rural residents was $45{\pm}15.1$mEq/day. 3) $K^+$ excretion of rural residents was similar to that of urban residents but because of the relatively high $Na^+$ excretion, $K^+/Na^+$ ratio was significantly lower than that of urban residents. In conclusion. salt intake and excretion of rural residents tends to have been decreased progressively and it is thought to be the result of the improvement in dietary life especially increased intake of animal protein.

Three experiments were conducted to investigate the interaction of breed-by-chitosan supplementation on the major economic traits in broiler chickens. In experiment 1, one-day-old broiler chicks were fed ad libitum on a basal diet (CON-group) or basal diet containing chitosan at an inclusion level of 10.5 mg/bird/day (EXP-group). The EXP-group birds in experiments 2 and 3 were supplemented from 15 day-old by the same amount of chitosan used in experiment 1. In experiment 1, the mean body weight of the EXP-group chickens was significantly (p<0.05) heavier in comparison with those of CON-group birds from day 21 of the experiment. Especially in 35 day-old mean body weight, the EXP-group birds of Arbor Acres, Peterson, and Ross were significantly (p<0.05) heavier by 121.8 g, 118.5 g, and 242.8 g than the CON-group birds, respectively. However, the mean body weights in experiments 2 and 3 did not significantly differ between the CON-group birds and the EXP-group birds fed with chitosan supplementation from day 15 post birth. In the comparisons among breeds on the mean body weight at 35 day-old, the birds of Arbor Acres were significantly (p<0.05) heavier than ones of Peterson or Ross; however, there were no significant differences between Peterson and Ross or Cobb and Ross birds in overall in the experiments. The mean 15-35 d FCR of the EXP-group birds in experiment 1 were significantly (p<0.05) lower at least in two of the three breeds (Arbor Acres and Ross breeds) than that of the CON-group birds. None of the mean 15-35 d FCR in either experiment 2 or 3 showed significant differences between groups within a breed. In all three experiments, the differences amongst breeds in the mean 15-35 d FCR were not great either. Significant differences were not generally shown in the mean percentage of abdominal fat deposition between groups within a breed in overall experiments except in the Cobb breed in experiment 3. The mean percentages of abdominal fat deposition were significantly (p<0.05) lower in Ross birds than in Arbor Acres or Peterson birds and in Cobb birds than in Ross birds. By the results of the analysis of variance, the interaction of breed-by-diet (chitosan) supplementation on any of the major economic traits including mean percentage of abdominal fat deposition was not significant in overall experiments. Results of these experiments indicate that dietary supplementation with chitosan for the improvement of growth or feed conversion ratio in broilers has an efficacy when the supplementation begins from day-old.

The effect of a chronic inflammation (cell-mediated immune response) on energy metabolism and growth performance was assessed in weanling piglets. Twenty four barrows of 4 wk of age were assigned to one of two immunization treatments : Control group [CON: immunized with Incomplete Freund's Adjuvant (lFA)] or Immunization group [IMMU: immunized with Complete Freund's Adjuvant (CFA)]. On d0, piglets were weaned and subcutaneously immunized at the medial side of the femur with 2 ml of IFA or CFA, respectively. Energy and nitrogen balances were measured per group during 13-d balance period, and total $(HP_{tot})$, activity-related ($(HP_{act})$) and non-activity-related $(HP_{cor})$ heat production were determined every 9-min by indirect calorimetry. Ig total titers to Mycobacterium butyricum, which is present in CFA, were higher (p<0.01) in IMMU than in CON on d13 (2.5 vs 1.8) and d20 (2.9 vs 1.8) after immunization. There were no differences (p>0.10) between treatments in rectal temperature, performance, feed intake, and availability and partitioning of energy during the balance period. Average daily feed intake was numerically higher in IMMU than in CON (0.34 vs 0.32 kg/d), but there was no difference (p>0.10) in metabolizability of the dietary energy between treatments. $HP_{act}/HP_{tot}$ was 16.24 and 16.89%, and retained energy was 251 and 268 $268\;kJ{\cdot}kg^{0.75}{\cdot}d^{-1}$ for CON and IMMU, respectively. Numerically, maintenance requirement of IMMU was even lower than that of CON $(419\;vs\;427\;kJ{\cdot}kg^{0.75}{\cdot}d^{-1})$. The present study suggests that a chronic inflammation has no effect on energy metabolism and growth performance, in spite of the difference in systemic antibody responses. The reason was considered to be due to locally induced immune response, resulting from the possible encapsulation at the site of injection, and/or to a low systemic immune stress which is within a functionally acceptable physiological range for the piglets.

Corn distiller's dried grains with solubles (DDGS) is a completely new feed ingredient in the Korean feed market. There is an ever increasing need for the Korean feed industry to import and make the best of it as a high protein and high energy feed ingredient. A layer feeding trial was conducted for 10 weeks to investigate the effects of addition of light-colored DDGS to layer diets on laying performance, egg qualities and yolk fatty acid composition. Also, the economics of using DDGS in the Korean situation was analyzed. Nine hundred Hy-line Brown layers, 24 weeks of age, were employed in a feeding trial consisting of four dietary treatments (0, 10, 15, and 20% DDGS), and five replicates per treatment. All experimental diets were prepared as iso-protein (17%) and iso-calorie (TMEn 2,780 kcal/kg). The use of DDGS up to 20% in layer diets did not exert any influence on feed intake, laying rate, total egg mass, mean egg weight and feed conversion ratio (p>0.05). The color and breaking strength of eggshell, as well as the albumin height and Haugh unit were not affected by the addition of DDGS up to 20% in the diet. The yolk color was significantly increased by DDGS supplementation (p<0.05). As the DDGS level increased, the oleic acid content decreased, and the linoleic acid increased (p<0.05) in egg yolk. The degree of saturation of yolk fatty acids was not affected by DDGS supplementation. The inclusion of light-colored DDGS up to 20% in layer diets resulted in a decrease of feed cost per kg without any undesirable effect on laying performance. In conclusion, the light-colored DDGS (L* 56.65) could be used up to 20% in layer diets without any harmful effect on laying performance, and possibly provide economic benefits to the Korean poultry industry.

In this study, we investigated the chemical and enzymatic properties of unmarketable cultured bastard halibut (UCBH) Paralichthys olivaceus harvested at different times (March, May, July, September, November, and January), and we examined the physical properties of surimi gel from UCBH as a potential source of surimi and surimi gel. The moisture and crude protein contents of UCBH harvested in July and January were >78% and <19%, respectively, which is greater than the moisture content in UCBH harvested in May, March, and September, but lower than the crude protein content. Regardless of the month of harvest, the UCBH had a higher crude protein content than Alaska pollock, which is the largest fishery biomass used for surimi and surimi gel, but a lower moisture content. Regardless of the month of harvest, the enzymatic activity in crude extracts of UCBH muscle ranged from 0.31-0.59 U/mg for casein (pH 6.0 and 9.0) and 11.7-12.7 U/mg for LeuPNA. These findings suggest that autolytic enzymes were unaffected by gel formation. Gel strength was highest in the surimi gel prepared from UCBH harvested in September, November, and January; second highest in that prepared from UCBH harvested in March and May; and lowest in that prepared from UCBH harvested in July. Compared to the gel strength of surimi gel from grade SA commercial Alaska pollock surimi, the strength of the surimi gels prepared from UCBH harvested in March, May, September, November, and January were superior, whereas that of the surimi gel prepared from UCBH harvested in July was similar.

Purpose: The purpose of this study was to measure accessibility and to examine distribution of restaurants in the local community. Methods: The target area of this study was two urban areas and a rural area in a city. We collected location information on all restaurants in target areas and classified all restaurants according to Korean food restaurants and Non-Korean food restaurants. We measured restaurant density per 100 m from the residences of the study population and calculated the distance of the nearest restaurant from the residences of the subjects using the Geographic Information System (GIS) analysis method. We compared the accessibility and distribution of restaurants in urban areas with that of the rural area, and compared the accessibility and distribution of Korean restaurants with that of Non-Korean restaurants. Results: Restaurants in urban areas were more dense than those in the rural area, and, in urban areas, restaurants were intensively distributed around the subjects' residence. Also, there were more Non-Korean food restaurants than Korean food restaurants in urban areas, and it was opposite in the rural area. Conclusion: It is important that we understood the current state of the restaurant environment in the local community using GIS analysis for the first time in the field of food environment. Further research is necessary on the association of restaurant environments and the dietary life of the population.

The effects of cheonggukjang (traditional fermented soybean food, CK) and cheonggukjang added Phellinus linteus (CKP) on lipid metabolism were investigated in adult male rats. Twenty weeks old Sprague-Dawley rats were fed a purified hyperlipidemic diet (control diet: 0.5% cholesterol, 10% fat, 18% casein) for 4 weeks. The rats were randomly assigned to each treatment group control, two kinds of CK or CKP (powders of CK or CKP as dietary protein sources) After 5 weeks of CK or CKP diets consumption, the body weights, the hepatic and epididymal fat pad weights of the CK or CKP diets groups were significantly decreased than those of the control group. The liver cholesterol and triglyceride levels were significantly lower in both the CK and CKP diets groups than those in the control group. The concentrations in serum triglyceride, total cholesterol, LDL-cholesterol, and atherogenic index ratios were significantly decreased in the CK and CKP diets groups compared with those in the control group. The HDL-cholesterol/total-cholesterol ratios were significantly increased in the CK and CKP diets groups compared with those in the control group. Fecal cholesterol and triglyceride excretion of the CK and CKP diets groups were significantly increased than those of the control group. These results showed that both the feeding of cheonggukjang and cheonggukjang added Pheilinus linteus decreased the triglyceride, total cholesterol and LDL-cholesterol in serum as well as the triglyceride and cholesterol in liver, and increased the HDL-cholesterol/total-cholesterol ratio in serum of the rats.

Objectives: The objectives of the study were to assess body composition, physical activity level (PAL), basal metabolic rate (BMR), and daily energy expenditure (DEE) and to examine associations between PAL and body composition, BMR, and DEE of elderly in Busan. Methods: A cross-sectional study was conducted among 226 elderly aged 65-93 years. Body composition was measured by Inbody 720. PAL was calculated by daily activity diary. BMR was calculated by Harris-Benedict (H-B) formula, Dietary Reference Intakes (DRI) formula, and Inbody 720 measurement. DEE was calculated by H-B formula, DRI formula, Inbody 720 measurement, and estimated energy requirements (EER) formula. Results: The mean fat free mass (FFM) in elderly men was significantly higher than that in elderly women (p<0.001). The mean percent body fat and fat mass (FM) in elderly women were significantly greater than those in elderly men (p<0.001, p<0.001). The mean PAL in elderly men (1.59) was significantly higher than that in elderly women (1.53) (p<0.001). The mean DEEs calculated by 3 methods except for H-B formula in elderly men were higher than EER for elderly men (2000kcal). The mean DEEs calculated by 4 different methods in elderly women were higher than EER for elderly women (1600kcal). Age showed significantly negative correlations with height (p<0.001, p<0.001), FFM (p<0.001, p<0.001), BMRs calculated by H-B formula (p<0.001, p<0.001), DRI formula (p<0.001, p<0.001) and Inbody 720 measurement (p<0.05 p<0.01) and DEEs calculated by H-B formula (p<0.001, p<0.001), DRI formula (p<0.001, p<0.001), Inbody 720 measurement (p<0.05, p<0.05), and EER formula (p<0.001, p<0.001) in elderly men and elderly women. PAL showed significantly positive correlations with FFM (p<0.05), BMR by Inbody 720 measurement (p<0.05) in elderly men and negative correlations with FM (p<0.05) in elderly women. Conclusions: Based on the results, PAL was associated with greater FFM in elderly men and lesser FM in elderly women. Therefore, nutritional education to increase physical activity for health promotion in late life is needed in the elderly.
