Liver and serum β-D-mannosidase activities were determined in ethanol intoxicated rats with extrahepatic cholestasis induced by common bile duct ligation (CBD) to manifest the biochemical background of alcohol drinking hazard under the hepatobiliary disease. Liver β-D-mannosidase activity and its Vmax value in CBD ligated rats with chronic ethanol intoxication were found to be significantly decreased than that in CBD ligation alone. However, the difference of Km value on above hepatic enzyme was not found between the experimental groups. On the other hand, serum β-D-mannosidase activity in CBD ligated rats with chronic ethanol intoxication was increased more than that in CBD ligation alone. These results indicate that the biosynthesis of the hepatic β-D-mannosidase decreases and the serum β-D-mannosidase activity increases in cholestasis combined with chronic ehtanol intoxication, reflecting damage of aggravated hapatocytic membrane. Accordingly, the resulting data supported the fact that alcoholic drinks were enzymologically harmful to the hepatobiliary disease.

Developmental anomalies of the aortic arch, commonly known as vascular rings, are relatively rare congenital vascular anomalies which can compress the trachea and esophagus. One routine chest film of a patient who was checked and hepatoma-diagnosed in Internal Medicine, Chosun University Hospital left the room for doubt of mediastinal mass. But no subjective symptoms for the mass was told by the patient. This is to report our experience of a patient having right side aortic arch with aberrant left subclavian artery, as proved by diagnosis, but none of congenital heart disease. This right side aortic arch with aberrant left subclavian artery is the most frequent type among right aortic arch, the anomaly of which is usually detected from the incidental suspicion for mediastinal mass at routine chest film; because no symptoms are accompanied therewith.

This paper proposed a kinematic modeling methodlogy and feedback control system based on kinematics for 2 Degrees of freedom of 4-wheeled mobile robot. We assigned coordinate systems to specify the transformation matrix and write the kinematic equation of motion. We derived the actuated inverse and sensed forward solution for the calculation of actuator velocity and robot velocities. Orientation error, which is defined as the difference between the actual robot orientation and the desired robot orientation. It is the most significant error and has the largest impact on the motion accuracy. To calculate the WMR position in real time, we introduced the Dead-Reckoning algorithms and composed two feedback control system. The simulation result show that the proposed kinematic modeling and control system are useful. We will easily extend the proposed kinematic modeling to mobile robot of similar type.

Purpose: The total number of times a paper is cited, also known as the impact factor (IF) of a medical journal, is widely implied in evaluating the quality of a research paper. We evaluated the citation index data as an IF of Korean J Pediatr in Korean Medical Citation Index (KoMCI) and Journal Citation Index (JCI) of Web of Science. Methods: We calculated the IF of Korean J Pediatr at KoMCI supervised by Korean Association of Medical Journal Editors. And we estimated the IF of Korean J Pediatr by the JCI of Web of Science although it was never officially reported. Results: The IF of Korean J Pediatr on KoMCI has increased from 0.100 in the year 2000, to 0.205 in 2008, and 0.326 in 2009. Although the IF of Korean J Pediatr was 0.006 in 2005, 0.018 in 2006, 0.028 in 2008, 0.066 in 2009, and 0.018 in 2010 according to the JCI of Web of Science, the number of citations are steadily increasing. Conclusion: Understanding and realizing the current status will be a stepping stone for further improvement. The next objective of the Korean J Pediatr is to become registered in the SCI or SCIE. Increasing the IF according to the JCI of Web of Science is crucial in order to achieve this goal.
