The glycosylation of glycoproteins from mammalian or plants can affect their efficacy, stability, solubility, and half-life. In the present study, we investigated plant glycosylation and their relative intensity (%) in a plant carbohydratebinding protein with the hemagglutination and antiproliferative activities. The hemagglutination activity on the deglycosylated protein was decreased as a 16-fold than that of intact glycoprotein. Using the HPLC with fluorescence detector and mass spectrometer, the major eight bi- or triantennary oligosaccharides containing xylose, fucose, mannose, galactose, and N-acetylglucosamine were identified and structurally characterized. The present results indicate that the oligosaccharides on this plant glycoprotein is necessary for their own property.

In this study, kinematic analysis and simulation of a linear-adjustment pipe-reproduction robot were performed. A straight adjustment pipe used in ships consists of two flanges and a straight pipe that connects the pipes of the ship at a precise angle. A robot that accurately reproduces a straight adjustment pipe is referred to as a reproduction robot. To accurately control a reproduction robot, the moving distance and rotation angle of the robot must be calculated accurately. For this purpose, the kinematics of a linear adjustment pipe reproduction robot were analyzed, and a simulation program was created based on the analysis results. The simulation results confirmed that the adjustment pipe on the drawing can be accurately reproduced using a reproduction robot. Therefore, the kinematic analysis and simulation results of the linear adjustment pipe reproduction robot performed in this study can be used to operate the reproduction robot.
