Pulses are an annual leguminous crop yielding from one to twelve grains or seeds. This study was used eight pulses except for green beans. We evaluated the chemical characteristics of these raw pulses produced in Korea. The nutritional and functional contents such as moisture, carbohydrate, crude protein, crude lipid, ash, dietary fiber, minerals(Ca, P, Fe, Na, and K), vitamins (A, E, C, B groups, folic acid, and niacin), total polyphenol, carotenoid, and flavonoid containing isoflavone were investigated. As a results, all raw samples were shown the high levels of almost nutritional contents (especially, protein, fats, and fat-soluble vitamins). In addition, yellow soybeans, red bean, and kidney bean were high the contents of total polyphenol. Of the functional contents, three lands of the yellow soybeans were shown the high flavonoid. This study represent much to provide the fundamental nutrition and function data in pulses because they have significant nutritional and health advantages for humans.

This study examined the components and physicochemical properties of citrus peel as a natural health food source by measuring the general and antioxidative contents of citrus peel. Total contents of carbohydrates, crude protein, crude lipid, and ash were 72.1%, 6.6%, 1.3%, and 3.7% respectively. Caloric content of citrus peel was 334.5 kcal, while total dietary fiber was 32.1%. Regarding mineral contents, Ca was the most abundant mineral, followed by K, Mg, and P. Total phenol contents of the 70% ethanolic extracts of citrus peel was $66.4{\pm}8.74mg\;GAE/g$. Total flavonoid contents of the 70% ethanolic extracts were $14.4{\pm}3.28mg\;RE/g$. The antioxidative activities of citrus peel were significantly increasing in a dose dependent manner on DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging, ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) radical scavenging, FRAP(ferric reducing antioxidant power) activity and reducing power. Therefore, the general nutrients and other antioxidant bioactive materials in citrus peel proved that citrus peel possesses a high potential materials as a nutritious food.

The physicochemical characteristics of fresh noodles made with blends of low-protein wheat flour and barley byproduct (BBP, $250{\mu}m$) were investigated. The crude protein contents (PC) of flour from Goso and Backjoong cultivars were 7.91% and 7.67%, respectively. PC and ${\beta}$-glucan contents from the BBP were 14.10% and 3.11%, respectively, which were higher than those in wheat flour. The water-holding capacity (WHC) of various blends was increased as a function of BBP but not gluten contents. Goso flour had the highest starch content (78.68%), with peak and final viscosities of 3,099 and 3,563 cp, respectively. Peak and final viscosities, trough, breakdown, and setback of the blends were decreased with the addition of BBP. Noodles made with Backjoong had the highest thickness score, while the hardness of noodles made with blends of Goso or Backjoong and 20% BBP were similar to those made from wheat flour only. The WHC of the samples was strongly correlated with PC, crude fiber, and ${\beta}$-glucan. The PC was not correlated with final viscosity, setback, thickness, hardness, gumminess, or chewiness.

This study compares the major nutritional components of the leaf, flesh, and seed of dry loquat (Eriobotrya japonicaLindl.). Among proximate compositions, the crude fat, crude ash, and dietary fiber of the leaf exceeded those of the seed and flesh, whereas the carbohydrate content of the leaf was lower than that of the seed and flesh. The main component of free sugars in the leaf, flesh, and seed was fructose. Total amino acids of the leaf, flesh, and seed were 552.43, 63.00, and 260.29 mg%, respectively. Although the amino acid composition of the leaf, flesh, and seed varied, glutamic acid and ${\gamma}$-aminobutyric acid were the major amino acids in the leaf, flesh, and seed. Major fatty acids of total lipid were oleic acid and stearic acid in the leaf and seed, and the major acid was linoleic acid in the flesh. Major organic acids were oxalic acid in the leaf, maleic acid in the flesh, and citric acid in the seed. Vitamin C content was higher in the seed than in the leaf and flesh.

This study was designed to explore the effects of marbling on meat quality characteristics and intramuscular connective tissue of beef longissimus muscle. Chemical determinations, histological and mechanical measurements were performed on the raw and cooked meat at d 4 postmortem. The results showed that crude fat, collagen, fiber diameter and maximum transition temperature of intramuscular connective tissue increased (p<0.05) with the increase of marbling score. The cooking losses, collagen solubility, WBSF and perimysial thickness decreased (p<0.05) with the increasing marbling. WBSF correlated (p<0.05) with moisture, crude fat, collagen, cooking losses, sarcomere length and perimysial thickness. The development of marbling results in the decline in cooking losses, the avoidance of sarcomere shortening, and the disorganization of the perimysia, which accounts for the improvement of beef tenderness.

Effects of the addition of \beta-glucanase to barley-based layer diets were examined by feeding 200 Leghorn layers with corn-based (Control) and \beta-glucanase supplemented diets (Barley+ Enzyme). The results obtained are sumrrarized as follows. 1. There were no siginificant (P>0.05) differences in hen-day egg production(%) and average egg weight between two treatments, indicating that the \beta-glucanase supplemented barley could successfully replace the commonly used corn in the layer diets. 2. Although there was no statistical difference (P>0.05) between two treatments, the daily feed consumption was numerically high in layers fed the barly diet compared to the corn-based diet. 3. Availabilities of crude fat and crude fiber of the barley diet were significantly poor (P<0.05) as compared to corn diet. 4. The \beta-glucarase supplementation depressed the viscosity of barley diets and excreta from therm. 5. Both serum and egg yolk cholesterol were not significantly affected by the addition of \beta-glucarase in the barley based diet. Our data indicate that the barley grain supplemented with \beta-glucarase can be sucessfully used as an energy source of layer diet when there is a price advantage. Although some possibilities to produce low cholesterol egg were recognized in this study, further studies pertaining to long-term feeding experiment and elucidaton of the metabolic interrelationship between serum and yolk cholesterol, are required to confirm the result.

In this study, we selected supplementary vegetable resources to develpe nutritious supplementary model of korean formula for infants and children, purchased and analyzed it to use with a model. We also referred to an old book about Korean vegetable resources and searched a form of vegetable resources. There are a lot of vegetable resources of various kinds which lied scattered in mountains and fields of our country. As for these, a beyond compare menstruation activity component is becoming clear with a lot of things. It is thought that depth search and study of these vegetable resources and practical application to a infant and child supplemen is desirable. Therefore, we choosed vegetable resources ; a Capsella brusapastoris, a Codonopsis lanceolata, Dandelion, a wild plant, a Tractylis ovata(dried), a Tractylis ovata(native), a Pine plant, a burdock, a JanDae, a Plantain, a HollpDae, which gathered in our country, and we analyzied priximate aomposition of sample (moisture, ash, total carbohydrate, crude fat, crude protein, dietary fiber) and micronutrient contents of sample (calcium, Iron, flavonoids, vitamin A, vitamin C, vitamin E).

The more N fertilizer, the more grass proportion (58 8, 240 kg N/ha) and the less white clover (Trifolium repens) (6 %, 240 kg N) under grazing utilization. The proportion of white clover was maintained about 27 % at 60 kg N/ha/yr and weed proportion was reached 33 %. Under the condition of differentiated N rates, the proportion of white clover was ranged from 10 to 36 % at 20 kg N/ha/cut which was allocated after every grazing and it probably dependent on differentiated N rates rather than total amounts of N applied annually. 53-74 % of total dry matter yield were concentrated at 1st and 2nd growth under grazing system and there were no great differences in dry matter yield at 3rd, 4th, and 5th growth in comparison with the variations of N rates. There was very significant relationship between the proportions of white clover and the amounts of N uptaken by herbage upto 180 kg N/ha. About 138 kg N/ha were uptaken by herbage without N fertilizer but only with white clover (31 %) as a substitute of N. In the amounts of crude fiber and crude protein by differentiation of N fertilizer, there were no any great variations and liveweightgain during grazing periods was reached 1583 kg liveweightlha.

To find out the nutrient contents of temperate grasses on the south and north slope, a field experiment was conducted with five forage species of Dactylis glomerata, Festuca arundinacea, Phleum pratense, Agrostis gigantea and Trifolium repens. It was treated by randomized block design with 4 replications and lasted from September, 1983 to October, 1986 in Suweon. The results obtained are summarized as follows: 1. Mean chemical compositions except NFE and crude fiber of the forage species on the south slope were a little more contented than that of north. But all crude components were significant difference among the species on the south and north exposure. 2. Production of TDN (total digestible nutrient), StE (starch equivalent) ME (metabolizable energy) and NEL (net energy lactation) of different grass species on the north slope were much more increased by 5-30% per ha (Dactylis glomerata by 5-876, Festuca arundinacea by 5%, Phleum pratense by 24-26% and Agrostis gigantea by 25-30%) than that of same grasses on the south, however, those of Trifolium repens were much more increased by 4 1-42% per ha in the south. 3. Mineral contents, Ca/P ratio and K/ (Ca + Mg) equivalent ratio of the species were slightly different between the exposures. But considering the factors of occuring grass tetany, those of the forage species on the north slope were better than that of same species on the south.

To find out the optimum fertilizer level for high yielding variety, Velox, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage crop in Sunchon National University from Mar. 2000 to Aug. 2000. The effects of nitrogen fertilizer on plant growth were significant but increasing rate of application in potassium and phosphate fertilizers above 6 kg/a had negligible effects on plant growth. The optimum nitrogen application level of fertilizers turned out to be 16-6-6 kg/l0a of N-P$_2$O$_{5}$-K$_{5}$O. Content of crude protein was highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate of fertilizer application. Furthermore, IVDMD was high and dry matter yield were highest at the optimum raterate
