As people need the lifelong education in the 21st century, our society launched cyber education as a new education paradigm two years ago. This study attempted to evaluate the operation system of five cyber demonstration universities in Korea. Research finding indicate that there leave room for improvement ion several aspects. This study suggests that cyber education in the future need to consolidate the 'humanware', 'hardware', 'software' and ' baseware' to function effectively as well as to solve the problems that have been appeared during the last two-year demonstration period.

Lactic acid bacteria (LAB) are probiotics that provide numerous beneficial effects on the host body, especially on the intestine. Combining several strains of LAB, we prepared a formulation containing four different LAB and studied its anti-inflammatory activity both in vitro and in vivo. The formulation significantly reduced NO production from RAW 264.7 cells treated with bacterial lipopolysaccharide, indicating that the formulation might include antiinflammatory activity. The formulation also suppressed inflammatory change induced by trinitrobenzene sulfonic acid (TNBS) in mice, where oral or rectal administration of the formulation protected the colon tissue from the damage by TNBS. Expressions of the IL-6 and FasL genes appeared to be down-regulated by the formulation in TNBS-treated colon tissues, suggesting that the suppression of those genes may be involved in the anti-inflammatory activity of the formulation.

Objectives: To evaluate the clinical characteristics and outcomes of nonradiographic axial spondyloarthritis (nr-axSpA) in Korean patients. Methods: A retrospective analysis evaluated 155 patients with nr-axSpA at a single tertiary hospital between January 2001 and January 2011. Baseline characteristics and clinical courses were reviewed and compared with those of patients with ankylosing spondylitis (AS). Results: The mean age at disease onset was 29. 5 ± 10. 8 years, and 52 (33. 5%) patients were female. The mean age at symptom onset was older (29. 5 ± 10. 8 vs. 25. 9 ± 9. 2, respectively, p < 0. 001) and the male to female ratio was lower (2:1 vs. 5:1, respectively, p = 0. 001) in patients with nr-axSpA compared with patients with AS. The proportion of females was higher among patients with late onset-SpA than early- onset nr-axSpA (55. 0 vs. 30. 1%, respectively, p = 0. 029). Among 74 patients with nr-axSpA, whose follow-up duration was more than 1. 5 years, 29 (39. 2%) patients progressed to AS during the follow-up period. The proportion of females was lower in progressors that that of non-progressors (13. 8 vs. 44. 4%, respectively, p = 0. 010). Presence of syndesmophyte and minimal X-ray changes at baseline were frequently observed in progressors compared with non-progressors (26. 7 vs. 0. 0 %, p = 0. 006 and 69. 0 vs. 35. 6%, p = 0. 005, respectively). Conclusions: The predominance of male patients is more prominent among Korean patients with SpA compared with Caucasians. Female nr-axSpA patients had late symptom onset and less progression to AS. X-ray changes at baseline were associated with radiographic progression.

An extract obtained from germinated brown rice was evaluated for protective effects against the adverse effects of a chronic high fat diet. C57BL6/J mice were divided into three groups; normal diet+water group (ND), high fat diet+water group (HD), high fat diet+brown rice water extract group (HD+BE) and fed for 8 weeks (6 day/week). The ND group diet was 11 kcal fat %. The HD group and HD+BE group diet were 42 kcal fat %. Weight gains were not significantly different between groups. However, abdominal fat % was 1.6-fold higher in the HD group than HD+BE group. Feed consumption was significantly higher in the ND group than HD group. Serum triglyceride, total cholesterol and LDL-cholesterol increased with a high fat diet, but decreased by brown rice water extract administration to the high fat diet group. Serum HDL-cholesterol decreased by the high fat diet, but increased by the brown rice water extract administration. Also, serum HDL-cholesterol/total cholesterol ratio was 2.3-fold higher in the HD+BE than the HD. Liver triglyceride and total cholesterol were not significantly different among groups. These data suggest that brown rice water extract administration improves the serum lipid profiles of C57BL/6J mice.

This study was designed to compare true digestible amino acid values for broiler offal meal with available amino acid values. Broiler offal meal was each force-fed to 6 intact and 6 caecectomised adult cockerels For each test, Cockerels were starved of food for 24 h, fed, and then excreta collected for 48 h. Crude protein, ether extract and ash of broiler offal meal were 50.5%, 16.7%, and 11.7%, respectively. True digestibilities of all seventeen measured amino acids were lower for caecectomised than intact cockerels, with the average difference being approximately 0. 10. True available amino acid of broiler offa meal was higher values for cystine and aspartic acid in intact than in caecetomised cockerels. Generally leucine, isoleucine and glutamic-acid were among the most available amino acids, while cystine, aspartic acid and threonine were among the least available amino acids in broiler offal meal for caecectomised cockerels.
