Abstract: Disclosed is a medical care standard knowledge-based decision support system that provides clinical decision-making information to a user group including medical-care-related staff in the care of patients, the medical care standard knowledge-based decision support system comprises: a client database; a master knowledge-based relational database; a console; and a medical-care-knowledge-guidance-indicators-constructing-storing device. The medical-care-knowledge-guidance-indicators-constructing-storing device includes a guidance-indicator-list-generating unit, which is configured to receive option judgment results, a knowledge-database-inference-engine is used to generate a plurality of values of weighted ratio and then calculate data of weighted ratio to generate a new guidance-indicator list, the knowledge-database-inference-engine is selected from a Clinical Diagnostic Validity model and a Bayesian decision model.

Abstract: A fitting construction used for connection of pipes comprising a first pipe assembly having an inner pipe and an outer pipe separated by a wall flange, a corresponding second pipe having a threaded end, a slip-nut having internal threads on its wall part, and first and second gaskets. Either the inner pipe or the outer pipe of the first pipe assembly is provided threads thereon for threadedly engaging or connecting to the second pipe. The second gasket is shaped and sized to be placed on an end face of the second pipe and compressed between it and the wall flange. The outer pipe has an externally threaded end for threadedly engaging the slip-nut with the first gasket being compressed between a cap part of the slip-nut and an end face of the outer pipe.
