  • This study was designed to investigate the nutritional effect of mugowrt powder supple mentation to rice diets with different protein levels. Thirty female albino rats weighing 39-43g were adopted for the feeding trial for 4 weeks. The different 5 kind of experimental diets were performed . Control diet was commercially available forage for rats, experimental diet (I-C) highly milled rice, (Ⅰ) highly milled rice 95% and mugwort powder 5%, (Ⅱ-C)highly milled rice 95% and milk casein 5%, and (Ⅱ) highly milled rice 90%, milk casein 5 % and mugwort powder 5%. Growth rate was remarkably high in the dietary group fed on highly milled rice supplemented with 5% mugwort powder (protein 8%) (P<0.05), but it showed the tendency to be rather low in the group fed on highly milled rice supplemented with 5% casein and 5% mugwort powder (protein 12%). Food efficiency as well as protein efficiency appeared similar to the growth rate. Hematodcrit level demonstrated the same tendency as growth rate, but hemoglobin content was observed to increase by diets supplemented with increasing amount of mugwort regardless of protein level. Each nutrient intake was increased by adding mugwort powder to diets after a week's feeding, but it was increased by 8% protein diet, and decreased by 12% protein diet in 3 weeks as well as 4 weeks after feeding . The absorption rate of carbohydrate and protein decreased by feeding mugwort supplemented diets regardless of protein level and feeding period, and that of lipid increased with 12% protein diet.

  • The west coast of Northern Borneo is strongly influenced by Asian monsoon. Present research using the satellite ocean color (OC) remote sensing has identified some interesting oceanographic phenomena in this area that could be related to the harmful algal blooms (HAB). Occurrence of seasonal upwelling event was noticed off the northern tip of Borneo Island that could be related to the northeast monsoon wind. Harmful algal blooms by Pyrodinium bahamense var. compressum occurred since 1976. Subsequently, during December 2003, there was a report of new HAB by Cochlodinium polykrikoides in Northern Borneo. Analysis of OC images revealed that the Cochlodinium bloom had very high chlorophyll a signal and strong absorption characteristics. Results showed that the Baram River plume and upwelling at Northern Borneo were the source of nutrient for the Cochlodinium bloom in the offshore region. Ocean color images of 2004 showed that the bloom from Northern Borneo had crossed the Balabac Straits, reaching Palawan Island in Philippine. Due to the possibility of transboundary HAB problem, we propose a regional HAB monitoring network for an effective HAB management.

  • It has been suggested that people who suffer from impaired masticatory function may adapt food consistency to their oral status (which may lead to deficient nutrient intake) or rely on the digestive system to compensate for the lack of oral preparation of food (which may increase the likelihood of digestive diseases and decrease gut absorption). Masticatory deficiency thus may be detrimental to health. This article reviews evidence of the effects of masticatory deficiency on nutrition. The selection of relevant literature was based on Medline queries using the following key words: mastication, nutrition, digestion, diet, and disease risk. Earlier work not listed in Medline but related to the subject also was reviewed. Only publications available in English were selected for inclusion. It is difficult to draw conclusions from many of the reviewed studies due to issues related to study design, confounding variables, and the subjective nature of the measurements. In particular, data supporting a link between masticatory function and deficient dietary intake often are based on relatively weak correlations and cannot confer a causal relationship.

  • A potato (Solanum tuberosum L. cv. Superior) cultivar was grown in aeroponic cultivation system to investigate the effect of root zone cooling in summer. Based on their nutrient uptake, growth responses, and tuberization, the possibilities for potato seed production were determined. Although shoot growth and early tuberization increased in the conventional non-cooling root zone system (root zone temperature of $25\pm2^{\circ}C$), stolen growth, photosynthesis, transpiration rate and number of tubers produced were higher in the cooling root zone system ($20\pm2^{\circ}C$) than in the non-cooling system. Increasing root zone temperature above $25^{\circ}C$ stimulated absorption of K more than T-N, P, Ca, Fe and Mn. On the other hand, root zone temperatures in the range of $20^{\circ}C$ to $25^{\circ}C$ did not affect Mg contents. The lower uptake and supply to leaves of T-N, Fe and Mn at the high root zone temperature promoted early tuberization and advanced haulm senescence. The results stress the importance of keeping root zone temperature to as low as below 20, particularly in summer under temperate Bone.

  • Experiment was conducted to study the effect of sources of dietary fiber on the intestinal morphology of geese. Sixty white Roman geese of two-week-old were divided randomly into six groups and were fed with isoenergetic and isonitrogenous diets which contain alfalfa meal, barley hull, rice hull, purified cellulose, lignin, or pectin as the major dietary source of fiber. Different sources of dietary fiber significantly influenced the villi height and the crypt depth in the duodenum, and the villi height and the muscle layer thickness in the ileum (p < 0.05). The duodenal villus in the geese that fed diets with alfalfa meal, rice hull or pectin supplemented were significantly longest ($968.5{\mu}m$), whereas the lignin group was significantly shortest villus and deepest crypt depth (p < 0.05). The thicknesses of the ileal and caecal muscle layer were significantly thicker in the geese fed with cellulose supplemented diets than in those fed with the other treatment diets. The caecum of the barley bran fed geese possessed significantly longest villi and the most thick muscle layers (p < 0.05). From scanning electronic microscopic observation, the leafy and plate-like in the duodenal villi morphology of geese represented a more effective nutrient absorption in the small intestine. The morphology of ileal villi in geese was similar from herbivorous rabbit and from the African Green monkey.

  • Arbuscular Mycorrhizal Fungi(AMF) is widespread symbiont forming mutualistic relationship with plant root in terrestrial forest in ecosystem. They provide improved absorption of nutrient and water, and enhance the resistance against plant pathogen or polluted soil, therefore AM fungi are important for survival and maintaining of individual or community of plant. For last decade, many studies about the functional variation of AM fungi on host plant growth response were showed that different geographic isolates, even same species, have different effect on host plant. However, little was known about functional variation of AM fungal isolates originated single population, which provide important insight about intraspecific diversity of AMF and their role in forest ecosystem. In this study, four AM fungal isolates of Rhizophagus clarus were cultured in vitro using transformed carrot (Daucus carota) root and they showed the difference between isolates in ontogenic characteristics such as spore density and hyphal length. The plant growth response by mycorrhizas were measured also. After 20 weeks from inoculation of these isolates to host plants, dry weight, Root:Shoot ratio, colonization rates and N, P concentration of host plant showed host plant was affected differently by AM fungal isolates. This results suggest that AM fungi have high diversity in their functionality in intraspecific level, even in same population.

  • Arbuscular mycorrhizal fungi (AMF) are one of the most widespread symbionts globally. Owing to their enhanced nutrient absorption capacity, AMF significantly contribute to the survival of individual plants and the ecosystem functioning. Community structures of AMF are affected by many environmental factors Inland wetlands have a different environment from common forest soils, therefore, plants inhabiting wetlands may have characteristic AMF communities. The purpose of this study was to compare the AMF communities in wetlands, among the species of host plants. We sampled the roots of 3 host plant species, Phragmites communis, Miscanthus sacchariflorus, and Trisetum bifidum with rhizospheres from 3 isolated areas in Upo wetland, Korea. We extracted DNA from AMF spores in rhizospheres and the roots of 3 plant species. We amplified 18S rDNA of AMF using AMF specific primer. As a result, we confirmed 9 species from 5 genera in AMF spores, and 5 species from 3 genera in plant roots. Funneliformis caledonium was the most dominant species in field soils, on the other hand, Diversispora aurantia was the most dominant species in plant roots. We confirmed that species diversity and abundance of AMF communities were different among host plant species. These results showed that the AMF community had specific to host plants in the inland wetland.

  • In many countries, goat milk is an excellent nutrient source and is less allergenic for children and the elderly. The casein composition of goat milk consists largely of ${\beta}$-casein and lower amounts of ${\alpha}_{s1}$-casein, which may interfere with digestion by forming solid curds in the human stomach. Goat milk contains small fat globules and large amounts of medium chain fatty acids for, better digestibility, as well as abundant minerals and vitamins with high absorption rates. Recently, the medical benefits of goat milk in different human disorders have been recognized, leading to an increased interest in developing functional foods with goat milk, particularly for individuals with malabsorption syndrome. However, the physiological and biochemical properties of goat milk are largely unknown. We review the importance of goat milk as a potential functional food by providing scientific evidence confirming its health benefits.

  • The elderly often experience difficulty while eating; this can include physical problems, such as chewing and swallowing. Furthermore, their salt intake can be high due to a diminished sense of taste and smell. This can result in a reduction in calorie intake and subsequent malnourishment. Currently, the number of food products available in the market that are targeted specifically at the older population is very low. Development of nutritional supplement-based foods for the elderly is expected to reduce these dietary problems and therefore prevent nutritional deficiencies within this population. Milk and other dairy products are excellent sources of nutrition in terms of both nutrient content and absorption rates. Dairy products have been consumed around the world for centuries, and therefore represent an excellent food source for the elderly. In addition, use of milk-derived ingredients, such as casein and calcium, will enable the development of a variety of food products and supplements targeted at this specific age group. In the future, it is expected that milk and other dairy products will be used to develop a variety of nutritious food items for the elderly in the domestic food market.
