A method has been developed of preventing or limiting formation of adhesions by administering to a site in need thereof, in the absence of or after bleeding or leakage of fluid has been substantially stopped, a self-assembling material which forms a barrier to formation of adhesions. When correcting a shadow of the foreign substance of the moving image data using the acquired foreign substance information and playing back the corrected moving image data, a selection is made whether to perform processing for correcting the shadow of the foreign substance of a frame based on the data size of the frame of the moving image data to be played back. The housing has a mating surface and a soldering surface opposite to the mating surface. A RFID sensor chip is coupled with the glucose sensor strip and the antenna.
