Cystic disease of the liver is observed with increasing frequency because of the common use of computed tomography and ultrasonography. Hepatic cyst does not present particular symptoms. However, depending on its size and location, symptoms like abdominal distension, or pressure effects on adjacent organs including bile ducts causing intermittent jaundice could appear. Patients with hepatic cyst usually show no elevation of liver enzyme, bilirubin, or liver function tests. Jaundice usually can occur in the patients when the cyst becomes large enough to cause exrtahepatic blocking of bile duct. We receotly experienced a 57-year old female complaining of generalized pruritus, which was diagnosed as non-parasitic liver cyst with obstructive jaundice. The diagnosis was confirmed by abdominal US, CT, ERCP and operation. Unroofing of hepatic cyst was performed, and 3 months later, she was asyrnptomatic and total bilirubin was normalized. We report this case with a review of the relevant literatures.

Transformation efficiency, virus multiplication and foreign gene expression were characterized in the insect cells transformed with Autographa californica nuclear polyhedrosis virus (AcNPV) immediate early 1 gene (lE1). Transformation efficiency of insect cells by AcNPV IE1 gene vector horboring foreign gene was approximately 8-fold higher in the Sf9 cells transformed previously with AcNPV IE1 gene than in the normal Sf9 cells. Virus multiplication and foreign gene expression of recombinant baculovirus in the Sf9 cells transformed with AcNPV IE1 gene were similar to those of the normal Sf9 cells. These results suggest that transformed cells displaying foreign gene product by using AcNPV IE1 gene promoter will be useful for the diverse applications of insect cells.

System engineering(SE) management techniques applied for space launch system development are introduced to assess the current status and address the effwctiveness of these techniques. Management plans and guides are prepared for the work breakdown structure , data, comfiguration, interface control, Quality assurance, procurement, reliability, risk and verification/validation . Further improvement is required for the system engineering management plan(SEMP) to merge the international cooperation into current engineering managment system.

In this study, a shape optimization of stiffener was conducted to increase buckling load or failure load in each case with a different design value and a different objective function for stiffened laminated composite panel of I-type under compression loading. Regarding each of buckling load or failure load as objective function, optimum design was carried out. In respect of optimum design, the effects of relative length of web and cab of stiffener on buckling load or failure load of postbuckling were investigated.
