The purpose of this study was to provide basic data regarding the perceptions of medicated diets among chefs. The subjects were 22 exemplary restaurant chefs in the Danyang area. The results showed that 40.9% of the chefs regarded the taste of medicated diets as good. Conversely, 22.7% of the subjects answered that they didn't know about medicated diets. Mass media and education from relevant institutions were the means of acquiring information about medicated diets. The chefs recognized that varieties of sauce could make medicated diets popular because of special flavor. Female chefs were generally more familiar with herbs than male chefs. Overall, the chefs were not familiar with Menthae Herba, Atractylodis Japonica, Adenophorae radix, Caryophylli Flos, or Carthami Flos. However, they were familiar with Glycyrrhizae Radix, Cassiae Semen, Cinnamomi Cortex, Polygonati Rhizoma, Mume Fructus, and Ginseng Radix, even though they didn't like the tastes pertaining to medicated diets. Ginseng Radix was the most well-known oriental herb, and Mume Fructus and Rubi Fructus were also popular. The most popular cooking methods for medicated diets were, in order, boiling rice, roasting items, and preparing the herbs as beverages.

A survey of ecological aspects of food, focused on breakfast of 1,526 adults with various professional occupations such as professors, teachers, employees of government, bank and company, and 1,928 students of various levels in the urban areas, was conducted from March, 1984 to February, 1985. The results were shown as follows: Significancy was found between appetite at breakfast, and bed time, status of sleep, eating outside the home on the previous evening, meal or snack of the previous late evening, and exercise before breakfast. The study showed that only 15.2% of the subjects had a good appetite at breakfast; 28.1% had a poor appetite; others had indifferences. About 45% of the subjects had their evening meal between 7pm. and 8pm.; bank employees had breakfast further later than 9pm.. Surprisingly, 31.3% of the subjects had snacks later than 10pm..Nearly one-fourth of subjects, in general, and 34.4% of the subjects in Seoul, had breakfast by themselves due to different schedules of family members. Breakfast patterns of the subjects during a period of 7 days were distributed as follows: 5.5 times for rice-oriented Korean meal; 0.6 times for bread type meal; 0.9 times for the omission of meal. The study described that the subjects who had bread type breakfast consumed only 3.7 items of food, whereas the subjects who had Korean breakfast consumed 7.1 items, on the average. Better breakfast eating habits for an adequate daily diet should be emphasized through nutrition education for adolescents and at the worksite.

This study was conducted to investigate the uses of Aster scaber. The survey methodology employed was a questionnaire, which was used to interview 272 (37.8%) males and 448(62.2%) females from the Seoul and Kyunggido areas. The main results are as follows: 40-50 years old like and eat Aster scaber more frequently than 10-30 years old. The most popular reason provided for the preferance of Aster scaber was good health benefits. People indicating a dislike for Aster scaber had generally fewer previous experiences of eating this plant. Respondents who regularly ate healthy foods preferred prepared Aster scaber to others foods(p < .001). The main purchasing place was traditional markets and supermarkets. The main cooking method was boiling with addition of seasoning. Aster scaber was purported as having the following characteristics "low calories and thus great as diet food'(4.03), 'ability to prevent adult disease'(3.95), 'high in vitamins and minerals'(3.89), and 'high fiber content which prevented constipation'(3.85). However, it was not associated with 'astringent taste'(3.51) and was regarded as 'fat accumulation restrainer and remover of heavy metal'(3.53). Recognition and eating experience was low for Aster scaber kimchi and rice bread, bread, sauce and Aster scaber added health drinks. However opinion of its taste was regarded highly.

Recent epidemological observations suggested beneficial effects of dietary fiber on man's health. With the increased emphasis placed on the requirement for dietary fiber in the diet, there has been greater interest in successfully incorporating dietary fiber into food products. Hence, in this study, several dietary fibers such as cellulose, pectin, rice bran, barley bran and job's tears bran were incorporated into julpyun to determine their effects on some physical properties and sensory characteristics. Difference of water binding capacity(WBC) was found among dietary fiber sources. The WBC of pectin was highest and that of job's tears bran was lowest. The moisture contents of julpyun were increased as WBC of added dietary fiber sources was higher. In the rheometer measurement for julpyun added with dietary fiber, hardness of julpyuns added with cellulose and pectin was low. But, hardness of julpyun added cellulose was increased rapidly during storage at 4$^{\circ}C$. Springiness and gumminess wereshowed similar aspects to hardness. In the retrogradation speed by Avrami equation, the rate constant of julpyun added barley bran was low ao retrogradation occurred slowly. The results of sensory evaluation, julpyun added no dietary fiber showed good overall preference. Overall preference in sensory evaluation showed positive correlation with the after-swallowing and color.

This study was performed to investigate the influence of dietary fibers from the whole foods on the serum lipid level and bowel function in rats. The fiber sources of experimental diets were prepared by drying and milling of cereal(rice bran), vegetables(Korean cabbage, radish), fruit(apple), and sea weeds(laver, sea tangle). Each of fiber sources was mixed into the diet to make the 5% level of total dietary fiber. Male rats of Sprague-Dawley strain were blocked into 8 groups : FF, CC, CE, V1, V2, ER, S1, and S2. The animals were fed ad libitum each of experimental diets for 4 weeks. Serum triglyceride level was not significantly different among groups. The laver group showed the lowest level in the serum total cholesterol. The Korean cabbage group showed the highest level in the serum HDL cholesterol. The longest transit time was observed in the fiber free group and the shortest transit time was observed in the sea tangle group. Absorption rates of calcium were especially lower in the Korean cabbage and the sea tangle groups than the other groups. Magnesium and phosphorus absorption rates were influenced by SDF(Soluble Dietary Fiber) intake and TDF(Total Dietary Fiber) intake, respectively. Mucosa weight in the small intestine showed the tendency to increase by increasing of IDF (Insoluble Dietary Fiber) intake. especially the Korean cabbage group was the heaviest. The activity of maltase in the mucosa of small intestine was the lowest in the radish group.

Estrogen deficiency is associated with increased body weight and fat mass, resulting in obesity-associated complications such as insulin resistance, cardiovascular disease, and type-2 diabetes. The present study was performed to investigate the effect of black rice (Oryza sativa L.) extracts (BRE) on body weight and fat mass in ovariectomized rats. Ovariectomized (or sham-operated) rats were randomly blocked into three groups (n=8~10 per group): sham operated group (S), ovariectomized control group (OVX), and ovariectomized group with BRE 30 mg/kg B.W. (BRE). High fat diet (fat calories 45%) was fed to all experimental rats for 12 weeks. Final body weight, weight gain, and body fat weight showed significant increases in the OVX group, whereas they were reduced by BRE supplementation. Serum TAG, T-chol level, and adipocyte size were not significantly different among the three groups. However, ovariectomy-induced hepatic steatosis was improved in BRE-treated group. Moreover, in the BRE group, serum leptin levels was significantly lower and fecal total lipid concentrations was significantly higher compared to the OVX group. The gathered data suggest that BRE is a potentially useful ingredient to protect against estrogen deficiency-related obesity and its related diseases.

In this study, two experiments were conducted to evaluate the total mixed ration with fermented feed (TMRF) and total mixed ration (TMR) by rumen in vitro fermentation and their effects on the growth performance and blood characteristics of Hanwoo steers. In experiment 1, three Hanwoo steers ($600{\pm}47$ kg), each permanently fitted with a ruminal cannula were used. In this experiment, three diets designated as T1, TMRF (18.4% fermented feed, tall fescue, mammoth wild rye forage and whole crop barley); T2, TMRF (17.7% fermented feed, rice straw and whole crop barley); and T3, TMR (rice straw, whole crop barley and probiotics, but no fermented feed), which were subjected to rumen in vitro fermentation for 48 h. The results demonstrated that DM disappearance rate gradually increased with advancing fermentation time, but T1 and T2 were higher than the T3 (p<0.05) from 3 h to 12 h, but insignificant (p>0.05) at 24 and 48 h. None of the specific VFAs were affected except for acetic and non volatile lactic acids, which were produced more in T2 than in T1 and T3 at 24 h and 48 h of incubation. A/P was lower in T1 and T2 than inT3 at 24 h (p<0.05) and 48 h (p>0.05) of incubation. These results confirmed that TMRF-related treatment shows a superior performance to that of TMR during the ruminal fermentation period. In experiment 2, the three diets in experiment 1 plus 1 more control diet (concentrates, probiotics and 2% rice straw of body weight) were fed to the 48 Hanwoo steers ($160{\pm}10$ kg) for a period of 168 d. The results demonstrated that the daily and total live weight gain and feed efficiency were higher (p<0.05) in the TMRF and TMR groups than in the control group. SGOT, SGPT and BUN (p<0.05) were reduced in TMRF relative to the control and TMR groups by 168 d which confirmed that TMRF shows better blood profiles than the TMR and control groups. Overall, these results appear to show that TMRF has better in vitro ruminal characteristics than those of TMR; growth performance and blood profiles were also found to be superior in TMRF than in the TMR and control groups. Thus, our findings suggest that TMRF-based feed supplies are favorable for Hanwoo cattle.

Two experiments were conducted to determine the effects of Leucaena leucocephala (leucaena) and Gliricidia sepium (gliricidia) supplementation on intake, digestion, outflow rates, microbial protein yield and live-weight changes in sheep fed with ammoniated rice straw (ARS). In experiment 1, three rumen cannulated Japanese Corriedale wether (mean body weight of 35.6 kg) in $3{\times}3$ Latin Square Design were used. Animals were fed ad libitum ARS alone, or supplemented with 200 g of either leucaena or gliricidia. In experiment 2, twenty-four growing native Philippine sheep with average body weight of $13.5{\pm}0.25kg$ were used in a completely randomized design (CRD) and offered similar diets to those of experiment 1. Supplementation increased total dry matter intake and nutrient digestibility except for fiber (p<0.05) without affecting ARS consumption. Nitrogen balance revealed that absorbed and retained N was significantly higher in leucaena and gliricidia. The significant improvement in N utilization and more digestible OM intake brought about by the inclusion of leucaena and gliricidia to ARS resulted in increased (p<0.05) microbial N yield. Efficiency of microbial N supply in supplemented group was not significantly different, but higher (p<0.05) than the 24.92 g N/kg DOMR for ARS group. Liquid outflow rate was 7.8 and 6.8 %/h, while the solid phase of rumen digesta was 4.4 and 3.8 %/h for the leucaena and gliricidia group respectively, which were significantly higher than 5.30 and 2.50 %/h in the control diet. The increase in total DMI resulted to higher (p<0.01) growth performance and efficient feed utilization. Average daily gain (ADG) was 19.3, 34.6 and 33.9 g/d for the ARS, leucaena and gliricidia respectively. It is therefore concluded that addition of leucaena and gliricidia to ARS in could increase nutrient intake and digestibility, subsequently improving N utilization and livestock performance.

Two experiments were conducted to evaluate the nutritive values of defatted rice bran (DRB) and examine the effects of its dietary supplementation on broiler performances. In Experiment 1, to measure true metabolizable energy (TME), nitrogen corrected true metabolizable energy (TMEn), and true amino acid availability (TAAA), 30g of DRB sample was forced-fed to each of 16 ISA-Brown roosters followed by a 48h collection of excreta. The TME and TMEn values for DRB were 2.19 kcal/g and 2.05 kcal/g, respectively. The mean value of TAAA of the 15 amino acids in DRB was 77.29%. In Experiment 2, a total of 72 Avian broiler chicks were divided into 4 groups with 3 replicates of 6 birds per replicate, and fed one of the experimental diets containing 0, 5, 10 or 15% of DRB. Feed intake, weight gain, feed conversion rate, and body composition were measured for 3 weeks. Although there were no significant differences (P$\geq$0.05), body weight gain and feed intake of chickens fed a diet containing 15% DRB were slightly higher than those of the other groups. From these results, it can be concluded that feed formulation using TMEn and TAAA of DRB is an effective method for assuring feed quality and DRB can be supplemented to broiler rations up to 15% level.

The purpose of this study was to investigate food habits of boy students and to know the difference in food habits between boy and girl students. A previous study had been conducted to girl students in 1998 and this study was carried to boy students in Oct. 2000 using the questionnaires. The subjects were 783 boy students in middle school, high school and university students living in Jeonbuk region. The average score of food habits was $4.09{\pm}1.72$ out of a possible 10(middle school students were $4.96{\pm}1.85$, high school students were $4.17{\pm}1.61$ and university students were $3.15{\pm}1.70$). The average is similar $4.11{\pm}1.63$ to girl students in 1998. The correlation coefficient between the score of food habits and standard of living, present residence, taking nutritional supplements, and sort of school was positive. As a staple food, cooked rice was preferred 95.9% of subjects and this result is similar to girl students of previous study. The most preferred side-dishes was different between girl and boy students. Boy students liked stew the best, but girl students liked Kimchi the best. The most preferred snacks was fruits and fruit juice. The portion of eating cooked rice in boy students (87.8%) was decreased than girl students(90.6%) at breakfast. The main meal to have soup & stew was supper and the most delicious meal was also supper, but primary meal skipped was breakfast. The reasons for skipping breakfast were lack of time(38.7%) and no appetite(17.6%), skipping lunch was missing a time to eat(8.4%), and skipping supper was no appetite(10.5%). Substitution food on no preparation of lunch basket was difference between middle and high school students and university students. Middle and high school students ate noodles and university student ate cooked rice. The preference of snack was that chicken(20.3%) was the best. The time of eating snacks was that anytime(38.6%) was the first, after supper(13.7%) was next. In order to improve the nutritional status of boy students, they must establish good food habits by eating three regular meals per day and balancing their diet. Especially university student must build their regular life style, so they would have three regular meals.
