Abstract: A sluice gate includes: a hinge coupled to the top of the discharge port of a sidewall of the water reservoir unit; a flap gate coupled to the hinge unit and rotating up and down around the hinge unit, wherein the flap gate is rotated downward to close the discharge port when overlapped with the sidewall of the water reservoir unit and is rotated upward to open the discharge port; a fan-shaped pull string pulley coupled to an upwardly facing surface of the flap gate when the flap gate is horizontal; a pull string lifting means installed above the water reservoir unit; and a pull string having one end connected to the pull string lifting means and the other end coupled to the flap gate, wherein a portion of the pull string is wound around the outer periphery of the pull string pulley that moves the flap gate.

Abstract: A method of executing and controlling a workflow process includes a request-response control process for coordinating activities between a plurality of entities, whereby an entity creates and sends a message requesting execution of an activity and another entity receives, parses and responds to the request. The message includes activity-specific data and activity status data. The activity status data signifies, for example, whether a corresponding activity has been successfully performed (i.e., completed) or failed. Process information, including control logic for the workflow process, is specified in an at least one uncompiled document, which may include an extensible stylesheet and an extensible markup language document. A document type definition defines the structure of the document. The control logic may include serial, AND-parallel, OR-parallel, XOR-parallel, CON-parallel and iterative instructions and a definition of successful completion and/or failure for an activity according to the control logic.
