BACKGROUND The learning curve cumulative sum (LC-CUSUM) test is an innovative tool that allows quantitative monitoring of individual medical performance during the learning process by determining when a predefined acceptable level of performance is reached. This study used the LC-CUSUM test to monitor the learning process and failure rate of anesthesia residents training for specific subspecial...

BACKGROUND Single balloon enteroscopy (SBE) is a recently developed diagnostic modality to assess small bowel mucosa. The data on learning curve of SBE is scanty. We aimed to assess the learning curve, diagnostic yield and safety of SBE. METHODS All patients who underwent SBE at our centre from December 2007 to December 2010 were included retrospectively. The clinical details, enteroscopy fin...

so far various methods for optimization presented and one of most popular of them are optimization algorithms based on swarm intelligence and also one of most successful of them is particle swarm optimization (pso). prior some efforts by applying fuzzy logic for improving defects of pso such as trapping in local optimums and early convergence has been done. moreover to overcome the problem of i...

Computerized dynamic assessment has been proposed as a solution to the practicality issues involved in ordinary dynamic assessment procedures. However, most of computerized dynamic assessment studies have addressed receptive skills (i.e., reading and listening). Responding to the scarcity of CDA studies of productive skills, the present study was an attempt to design and implement a computerize...

INTRODUCTION Surgeons gain expertise as they repeatedly conduct a procedure. Such learning is widely acknowledged to pose a challenge to evaluating new surgical procedures. Most surgical trials report little if any information on learning. We elicited surgeons' belief regarding learning within the context of a randomised trial which assessed two surgical procedures. MATERIALS AND METHODS Surg...

In [Bus87] and [BP90] some ‘discovery procedures’ for classical categorial grammars were defined. These procedures take a set of structures (strings labeled with derivational information) as input and yield a set of hypotheses in the form of grammars. In [Kan98] learning functions based on these discovery procedures were studied, and it was shown that some of the classes associated with these f...

There are few demonstrations of basic associative learning phenomena using appetitive procedures in mice. This article describes procedures for obtaining four associative learning phenomena in mice, using an appetitive conditioning procedure in which the reinforcer was delivery of a sucrose pellet, and the conditioned response head entry into the food tray. Experiment 1 demonstrated latent inhi...
