We analyzed ERCP findings of 15 patients with clonorchiasis, that were confirmed by stool examination and operation from May, 1976 to September, 1980. The results were as follows. 1) Filling defects due to adult worm of clonorchis sinensis were significant direct findings of clonorchiasis. 2) Irregular stenosis, fuzziness, raggedness, peripheral dilation and disturbance of peripheral filling of intrahepatic bile ducts were significant indirect findings of clonorchiasis. 3) ERCP was excellent method to evaluate biliary tree in patients with clonorchiasis, who showed obstructive jaundice.
Synthesis of nanocrystalline SnO2 by a selective dissolution of copper alloy dross

In this report, preliminary study on concentration and separation of tin (Sn) from copper alloy dross using selective dissolution method was performed. The tin in the copper alloy dross did not dissolve in an aqueous nitric acid solution which could allow the concentration/separation of tin from the copper alloy dross. Precipitation of tin as H2SnO3 (metastannic acid) occurred in the solution and transformed to nanocrystalline tin dioxide (SnO2) after drying process. The dried sample was heat-treated at low temperature and its phase characteristics, surface morphology and chemical composition were investigated.

Development of the economy and the growing income of people interested in the leisure and health has been focused.

In this study, focusing on electrical energy using a water cooler to understand the structure and principles of fire, the fire revealed the mechanism is vulnerable to the consideration of factors, the exact cause of the fire investigation and the Assistant, manufacturing defects, and to contribute to fire prevention review should.

Cultural assets of the country's history and cherish the living conditions of the people, conscious and cohesive crystals, and the pride of the hearts of the people as a haven. In the country worth preserving national treasure, bomulgeup, local cultural heritage as a major cultural property protection are.

The national cultural assets, such as the many temples, vows to fire one if the loss of a centuries-old cultural property is a big loss of national posterity to great shame is not. Still cultural assets and a large number of visitors have flocked temples. All of us to keep the look and feel of the cultural assets pleasure to conserve cultural assets preserved to ensure that fire prevention is always unmistakably bear in mind that sees.
