웹을 기반으로 한 협동학습 시스템의 경우 학습자 모두가 공동의 학습 목표를 가지 고 원활한 사회적 활동을 통해 학습 과제를 해결 할 수 있는 학습 환경을 조성해 주는 것이 중요하다. 그러나 시간과 공간의 제약을 극복하여 학습 컨텐츠에 접근할 수 있는 장점을 가지고 있지만 이를 지원하고 적용하기 위한 적절한 상호작용 도구가 부족할 뿐 만 아니라 기존에 개발된 협동학습 시스템의 경우 대화방의 형태가 대부분이어서 학습 자간의 상호작용이 원할 하지 못한 실정이다. 따라서 본 연구에서는 웹기반에서 다양한 상호작용을...

The success of immunological control methods is dependent upon the use of potential key antigens as tick vaccine candidates. Previously, we cloned a gene encoding 27 kDa and 30 kDa proteins (P27/30) of Haemaphysalis longicornis, and identified the P27/30 is a troponin I-like protein. In this study, the recombinant P27/30 (rP27/30) expressed in Escherichia coli was used to immunize mice and the mice were challenge-infested with ticks at different developmental stages of the same species. The...

Black Bengal bucks (Capra hircus) were supplemented with 0, 0.2 or 0.4 mg elemental chromium (Cr) as chromium chloride hexahydrate per day for 70 days. Intake of dry matter (p <0.001), crude protein (p < 0.001) and neutral detergent fiber (p <0.01) increased due to Cr supplementation. The apparent total tract digestibility of dry matter (p <0.01), organic matter (p <0.05), crude protein (p <0.001) and acid detergent fiber (p <0.01) improved and the total body weight gain and the live weight gain...

Escherichia coli O157:H7 is recognized as a significant food-borne pathogen, so rapid identification is important for food hygiene management and prompt epidemiological investigations. The limited prevalence data on Shiga toxin-producing E. coli (STEC) and E. coli O157:H7 in foods and animals in Korea made an assessment of the risks difficult, and the options for management and control unclear. The prevalence of the organisms was examined by newly developed kit-E. coli O157:H7 Rapid kit. For the...

Tea is a popular beverage. Recently, green tea was reported to increase the number of peroxisomes in rats. In this study, to find out whether the green tea-induced proliferation of peroxisomes is mediated by PPARalpha , a transient transfection assay was carried out to investigate the interactions of tea extracts (green tea, black tea,oolong tea and doongule tea) and tea components (epigallocatechin gallate, epigallocatechin, epicatechin gallate, epicatechin and gallic acid), with mouse cloned...

The hatchability of sheep gastrointestinal nematode eggs exposed to ultraviolet (UV) radiation and the activity of the hatched larvae were examined. Hatchability decreased with increasing exposure to radiation. The difference in hatchabilityof eggs irradiated for 15,30 and 60 minutes were highly significant (p < 0.01 dα = 3.07, 3.24 and 3.75) compared with the hatchability of the nonirradiated eggs. The life span of irradiated larvae was shortened, only 20% of those expose to UV...

The immunomodulatory and antitumor effects of lactic acid bacteria (LABs) were investigated. Cytoplasmic fraction of Lactobacillus acidophilus, Lactobacillus casei and Bifidobacterium longum were tested for the antiproliferative activity in vitro to SNUC2A, SNU1, NIH/3T3 and Jurkat cell lines by crystal violet assay. All cytoplasmic fraction suppressed proliferation of tumor cells, though L. casei and B. longum were more effective. From these results, cytoplasmic fraction of L. casei and B....

Pharmacokinetics of cefotaxime (50mg/kg, i.m.) were studied in both healthy and kidney damaged female black Bengal goats. Uranyl nitrate (0.75mg/kg) was administered intravenously, once daily for five consecutive days to induce kidney damage. The pharmacokinetic variables were calculated in both cases. Kidney damage caused several changes in the determined variables. The Cmax and Cmin of cefotaxime observed at 0.50 and 5 h in normal goats were 24.91 ± 1.51 and 1.22 ± 0.07 μg/ml, respectively,...
