A method for entrapping migratory antigen presenting cells and particularly Langerhans cells in vivo is provided. A singlecrystal silicon substrate is bonded through an SiO2 film to a singlecrystal silicon substrate, and the singlecrystal silicon substrate is made into a thin film. The method also involves accessing evidence data, and deriving information about the behavior of the target system for the evidence data based on the tree-structured belief network. Each of the text bitmaps are composited with an image bitmap of a source image, wherein the composited image bitmap comprises a rendering of the block of text onto the source image. Each of the block design files corresponds to an implementation of its corresponding block. In the gland packing 4, ends 1a, 1b in the width direction of each of the braiding yarns 3A to 3H constituting the gland packing are directed to the inner side in the width direction, and the reinforcing fibers 2A to 2H protruding from the ends 1a, 1b are confined to the inner side of the braiding yarns 3A to 3H.
