  • 최근 360 및 VR(Virtual Reality) 영상의 구성 및 전송을 위해 Facebook이 기존 메르카토르도법을 사용하는 것 대신 "Transform"의 방법을 제시하여 큐브 및 피라미드 형태로의 이미지 전송하는 방식을 발표했다. 본 논문은 이 변형기법을 기반으로, 6개의 카메라로 360VR영상을 촬영할 경우 "Transform"이 가지는 큐브 형태를 이용 기존보다 효과적이고 가벼워 실시간 스트리밍에 적합한 360VR이미지 변형법을 제안한다.

  • Subacute toxicity of Hantabax, epidemic hemorrhagic fever vaccine, was investigated in Sprague-Dawley rats with subcutaneous injection. Any significant toxic clinical symptom was not observed in the treated rats during the experimental period. Macroscopic examination on the organs of tested animals showed no abnormal findings. On autopsy, no significant changes were found in organs examined.

  • From methanol extract of Acanthopnanax senticosus, six platelet anti-aggregating compounds, chiisanogenin (1), chiisanoside (2), ursolic acid (3), oleanolic acid (4), b-sitosterol (5) and daucosterol (6) were isolated. All of the isolated compounds showed dose-dependent inhibitory activities to rat platelet aggregation induced by all the agonist employed. Compound 1 showed about 50 folds higher potency than acetylsalicylic acid (ASA) on U46619 induced platelet aggregation (IC$\sub$50/ : 6.21 ${\mu}$M) and 10 ∼ 20 folds higher effect than ASA on epinephrine and arachidonic acid (AA) induced aggregation (IC$\sub$50/ ; 2.50 and 4.81 ${\mu}$M, respectively).
