Obstruction of the extrahepatic bile ducts is the most common cause of conjugated hyperbilirubinemia in early infancy. More than 90% of such obstructive lesions are accounted for by extrahepatic biliary atresia. A rare lesion is obstruction of the common duct by impacted, thickened secretions and bile. Bile plug syndrome is defined as extrahepatic obstruction of the bile ducts by bile sludge in term infants without anatomic abnormalities, congenital chemical defects of bile, or hepatocellular lesions. Obstruction of extrahepatic ducts by plugs of biliary material apperas to be due to the inspissation and precipitation of bile and mucus within the lumen of the ducts. Cholestasis and precipitation of bile develop in association with abnormal composition of bile in cystic fibrosis, hepatocellular damage, prolonged erythroblastic jaundice, altered biliary dynamics with total parenteral nutrition, gut dysfunction, diuretic therapy, exchange transfusions and perinatal hemolysis. In those cases, the term inspissated bile syndrome is used. The clinical and laboratory findings in bile plug syndrome are identical to those observed in biliary atresia and choledochal cyst. The diagnosis can be suspected based on the findings of clinical and laboratory examinations together with hepatobiliary imaging, ultrasonography, radionuclide scan and liver biopsy. We experienced a case of spontaneous resolution of bile plug syndrome in a 4-year-old girl. We report this case with brief review related literatures.

This paper proposes a new control method for a swarm of mobile robots to formation patterns while avoiding collisions between them. The swarm formations are made without any external controls during the motions of the mobile robots. Each individual robot needs to go to its predetermined terminal target region while avoiding collisions with the other robots. This study assumes 2-D planar motions in forming multiple shapes. In order to form a easily recognizable shape when the robots finish their motions, it is proposed that the concept of velocity field is used, based on an artificial potential
에스테르 交換反應에 對한 醋酸鹽 觸媒의 影響에 關한 硏究

The transesterification reaction between dimethylphthalate and ethyleneglycol was kinetically investigated in the presence of various metal acetate catalysts at 185℃ The reaction was followed by the measurement of distilled methanol from the reaction vessel. The transesterification was found to obey thiry-order kinetics with respect to dime thylphthalate and ethyleneglycol and catalyst. From the examination of relationship between rate constants and reciprocal absolute temerature, the activation evergy has been calculate as 25.90 Kcal with cobalt acetate catalyst. The highest reactivities were found for the metal acetate catalysts with the electron egativity values between 1.4 and 1.7.
