OBJECTIVE The potential difficulty in doing initial dilation in the percutaneous dilational tracheostomy (PDT) with the Ciaglia Blue Rhino (CBR) technique has been reported by others and encountered in our clinical practice. To resolve this problem, we developed a modified CBR technique by using a guidewire dilating forceps (GWDF) to facilitate initial dilation. The present before-and-after com...

Carbonyl reductase (CBR) is a cytosolic NADPH-dependent oxidoreductase metabolizing prostaglandins, steroids, quinines, and anthracycline antibiotics. Many experimental studies have shown that CBR plays important roles in the regulation of tumor progression, but clinical significance of CBR status remains unclear. Thus, we conducted a retrospective study on CBR mRNA expression in lung cancer. T...

This tutorial article introduces the concepts and applications of Case-based Reasoning (CBR) systems. The first section briefly describes what is CBR, when to use CBR and why use CBR. The second section looks at the description and indexing of cases in CBR systems. The retrieval and adaptation processes for finding solutions are outlined in section three. Learning and maintenance of CBR, due to...

This work is the second part of a general similarity-based theory of case-based reasoning (CBR), which moves CBR towards a firm theoretical foundation based on similarity-based reasoning. This paper will first examine abductive CBR and deductive CBR and propose a knowledge-based model for integrating abductive CBR and deductive CBR. It then proposes similarity-based models for rule-based and fu...

In this paper, we proposed a hybrid system to combine the self-organizing map (SOM) of neural network with case-based reasoning (CBR) method, for sales forecast of new released books. CBR systems have been successfully used in several domains of artificial intelligence. In order to enhance efficiency and capability of CBR systems, we connected the SOM method to deal with cluster problems of CBR...
