This invention relates to the field of therapy and diagnostic methods for ulcerative colitis. Two detachable rolls separated by a roll gap are driven in opposite directions and mounted on shafts to rotate in a machine frame. An activation time can be computed for each of the plurality of points as a function of corresponding local activation vectors. A transcoding server may communicate with a web browser via HTTP and communicate with a remote machine via a remote desktop display protocol. In a case where the conversion candidate character strings do not fit within the row or column, the conversion candidate display unit causes the conversion candidate character strings to scroll within the row or column upon receiving a flick operation. The delta information for the web page and a reference to the template can be separately sent to the client.
