  • To determine optimal plant density of forage rye in southern areas of Korea, forage rye cv. Paldanghomil, the highest yielding variety among experimental varieties of forage rye, was grown under five different plant density. Yield components such as plant height, and number of leaves were highest at the broad casting. Plants sown at broadcasting also showed highest fresh and dry matter yield. When plants were grown of the broad casting, they showed higher values in content of crude protein and lower values in contents of crude fiber such as neutral detergent fiber(NDF), acid detergent fiber(ADF), cellulose and lignin. There was no relationship between variation of in vitro dry matter digestibility(IVDMD) and plant density. Plants sown at the broad casting showed highest digestible dry matter yields.

  • In order to find out nutritional effects of Korean edible mushrooms on the multiplication of tissue cells, the alcohol extracts and acid bydrolysates of eleven species of mushrooms were added to Earle's ESS. A comparison of the respective multiplications of HeLa cells in this solution and in control solution of TC=199. Yielded the following result: The alcohol extracts and acid hydrolysates of a Coprinus comatur, Agaricus campestris, Agaricus bisporus, Lentinus edodes, Tricholoma matsutake, Pleurotus ostretus, Ramaria botrytis and Pholiota nameko influenced favorably the maintenance of the normal form and monolayer of HeLa cells. The growth curves of HeLa cells in the cultures containing, respectively, the alcohol extracts and acid hydrolysates of these eight mushrooms showed that five species, i.e., Coprinus comatus, Agaricus compestris, Agaricus bisporus, Lentinus edodes and Tricholoma matsutake effected an excellent multiplication and that the other three species were less effective than those five species. As to the effects on the cell multiplication, no marked difference was observed between the alcohol extracts and the acid hydrolysates of the mushrooms tested.

  • This paper describes a methodology for conducting Community Nutrition research with rather than on people in a community to generate grounded theory. This collaborative grounded theory methodology incorporates local knowledge and wisdom and builds community leadership capacity through engaging community-based professionals and para-professionals in the research process. In addition to building capacity for participation and leadership in research, education and action, this approach can increase the validity and value of the research and facilitate its application in community led programs. The methodology has five components: background, study design, data gathering, data analysis and interpretation, and application of findings in community programming. Three stages of the data analysis component focus sequentially on each interview independently, comparing across interviews, and systematically testing theory developed in the first two.

  • In batch cultures of Lactobacillus delbrueckii, cell growth and lactic acid production were affected by two main factors, inhibition by lactic acid and limitation by nutritional components. In order to increase th productivity significantly, a continuous stirred tank reactor with cell recycle was employed. A cell desnity of 145g dry weight/l and a volumetric productivity of 73 g/l$\cdot $h were obtained with an effluent concentration of 85 g/l lactic acid. The productivity achieved by this system was 23-fold higher than those obtained by the corresponding batch cultivations. Once the lactic acid concentration reached the steady steady state, lowering the yeast extract concentration caused the reduction of the lactic acid concentration without affection the biomass concentration. Finally, the formation of D-lactate was investgated. During the various cultures, a small amount of D-lactate always formed, even thought a majority of lactate was L-isomer, It was supposed that the relative amount of the D-lactate was affected by glucose limitation, and there seems to exist a certain relationship between the concentration of D-lactate and acetate.

  • Cholestasis results from impairment in the excretion of bile, which may be due to mechanical obstruction of bile flow or impairment of excretion of bile components into the bile canaliculus. When present, cholestasis warrants prompt diagnosis and treatment. The differential diagnosis of cholestasis beyond the neonatal period is broad and includes congenital and acquired etiologies. It is imperative that the clinician differentiates between intrahepatic and extrahepatic origin of cholestasis. Treatment may be supportive or curative and depends on the etiology. Recent literature shows that optimal nutritional and medical support also plays an integral role in the management of pediatric patients with chronic cholestasis. This review will provide a broad overview of the pathophysiology, diagnostic approach, and management of cholestasis beyond the neonatal and infancy periods.

  • Television food advertisement is the most effective way to reach to consumers with food and nutritional informations and affect their eating behavior. Therefore, 218 food commercials were reviewed using video tapes and copies to know the present food product trends, food messages they transmit and define misleading food commercials. Messages were focused on the benefit of health promoting substances they contain, especially for functional food components, fortified nutrients, food safety focused on food additives, convenience and differentiation with other products. Overnutrition on specific nutrients could be expected due to nutrient fortified products and misleading of food commercials were also noted. Regarding trends, guidelines provided by television broadcasting company shoud be fortified in the connection of Food Hygine Law and supervision committe should reinforce the food company to summit data for the approval of their advertisement claims. Nutrition educational spot program shoud be produced and broadcasted for the public to protect the consumer from food faddism in near future.

  • To measure nutritional components and physical quality of Wanja-jeon(Korean pan fried meat balls)was investigated during storage in a simulated hospital cook/chill foodservice system. The Wanja-jeon was cooked and stored for 4 weeks in chill conditions of 2 and 7$^{\circ}C$ and then reheated in the microwave oven. Moisture, protein, and fat contents were decreased little during 4 weeks storage at 2 and 7$^{\circ}C$. Total unsaturated fatty acids(TUFA) and polyunsaturated fatty acids(PUFA) increased slightly at 7$^{\circ}C$ storage. Total free amino acid contents were reduced after 4 weeks of storage, while total amino acids were affected little during chilled storage. However, volatile basic nitrogen(VBN) increased during the 4 weeks storage from 11.2mg%, immediately after cooking, to 14.1~14.2mg%. After reheating, thiobarbituric acid(TBA) value increased more significantly to 0.19 and 0.20.

  • Hepatic fibrosis is a common chronic liver diseases, characterized by the excessive deposition of extracellular matrix (ECM). Activation of hepatic stellate cells (HSC) is proliferative and fibrogenic and accumulating ECM. Transforming growth factor $(TGF)-{\beta}1$ is a critical mediator of HSC activation and ECM accumulation leading to fibrosis. Tenebrio molitor (TM), known as yellow mealworms, is reported in many countries as the nutritional value of foods. Our study has aims of finding liver function improvement effect of S. cerevisiae fermented Tenebrio molitor (SCTM) in vitro model. SCTM regulates $TGF-{\beta}1$ induced hepatic fibrosis via regulation of the $TGF-{\beta}1/Smad$ signaling. Also, we compared the components increased by yeast fermentation. It is possible to make a useful insect-derived alternative food in the improvement of hepatic liver disease.
