Only blood transfusion of the wrong ABO group will be expected to produce an immediate interference with renal blood flow except very few exceptions. But, very occasionally, despite apparent compatibility in vitro, transfused red cells are destroyed ed sufficiently rapidly idly to produce a hemolytic transfusion reaction. On the other hand, there are some cases in which severe reactions occurred following the transfusion of apparently compatible blood in these cases a blood group antibody was demonstrated in the patient's serum after transfusion although it could not be demonstrated in the pre transfusion serum. We present here very similar two cases. Acute renal insufficiency after ABO group and Rh-D compatible blood transfusion in our cases may be due to. 1. Rapid destruction of transfused red cells without demonstrable antibody. 2. Hemolysis due to blood group antibody only temporarily absent. 3. Hemolysis due to high temperature or unknown factor. 4. Hemolysis due to inadequate container within blood collecting bottles.

원래 신호의 spectral magnitude정보를 모르고 phase 정보만을 가지고 그 신호를 복원하는 magnitude retrieval problem을 본 논문에서 시도하였다. 본 반복법에서는 원래 신호와는 전혀 다른 초기 신호의 spectral magnitude로 일정 함수를 취하는 기존의 방법 대신에 지수함수를 도입하여 수렴 속도를 개선하였다. It is an important fact that the original signal can be reconstructed from a partial information, only spectral magnitude or phase, of the signal by an iterative method. In this paper, a faster algorithm was developed to increase convergence rate to the reconstructed solution using the exponential function instead of constant function of the spectral magnitude of the given signal.

The objective of this study is to investigate effects of prebuckling on the buckling of laminated compostie cylindrical shells. Both axial compression and lateral pressure are considered for laminated composite cylindrical shells with length to radius ratios. The shell walls are made of a laminate with several symmetric ply orientations. The study was made using finite difference energy method, utilizing the nonlinear bifurcation branch with nonlinear prebuckling displacements. The results are compared to the buckling loads determined when membrane prebuckling displacements are considered.
