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.

Abstract: The present invention discloses a system and method for creating a personalized template which enable a person who monitors workflows to selectively set up search objects, analysis conditions and presentation conditions and create and manage an appropriate template.

Abstract: The present invention discloses a workflow system for managing versions of a document, which can manage a variation history of the document and minimize the stored data of the document, and a method for managing versions of a document using the same. The workflow system includes the workflow engine, which consists of a flow control module for generating a control command according to a command from a client computer or self operation, a DB storage module for storing process definition defined in the client computer and information on a document file stored in an EDMS server in a database, and a file management module for calling a function for managing the document file from the EDMS server, and the adapter module for interface between the workflow engine and the EDMS server.

Abstract: A method for modeling an internal object of a human body includes the step of obtaining the original three-dimensional volume data of the internal object of a human body utilizing an ultrasonic imaging device. Thereafter, a desired area of the obtained original three-dimensional volume data is selected and the image quality of the desired area is enhanced. The desired area of the three-dimensional volume data is transformed into a fair shape data. The fair shape data is decimated while a modeled shape is maintained. Finally, a three-dimensional model is shaped using decimated shape data.

Abstract: A ferroelectric liquid crystal display is supplied with voltages by STN driving IC's, and a bias voltage circuit for generating voltages supplied to bias pins of driving IC's is provided. The two composite voltages are supplied to liquid crystal cells during the pixel period and the kinds of composite voltage is five or six. In order to supply these composite voltages to the liquid crystal cells, control signal pins of STN driving IC's are supplied with a signal which is "high" during the first half of pixel period and "low" during the latter half of pixel period, and bias voltage pins are supplied with voltages which should be applied to common electrodes and segment electrodes. The circuit for generating bias voltages such voltages includes a plurality of resistors and two power supplies. Thus, the ferroelectric liquid crystal displays can be economically driven, and the flickering of a picture is decreased.
