Laparoscopic surgical skills evaluation of surgery residents is usually a subjective process, carried out in the operating room by senior surgeons. By its nature, this process is performed using fuzzy criteria. The objective of the current study was to develop and assess an objective laparoscopic surgical skill scale using Hidden Markov Models (HMM) based on haptic information, tool/tissue inte...

BACKGROUND Studies demonstrate that both doctors and patients may use adrenaline auto-injector improperly and the usage skills are improved by training. In this study, we aimed to determine the appropriate frequency of training to maintain skills for adrenaline auto-injector use. METHODS We invited all interns of 2011-2012 training period. At baseline, all participants were given theoretical ...

Individual differences in skill acquisition are influenced by several architectural factors. According to Ackerman’s theory, general intelligence, speed of proceduralization and psychomotor speed influence different stages of skill acquisition. The ACT-R cognitive architecture allows for direct testing of this theory by manipulating parameters that correspond to these factors. The present study...

OBJECTIVES Basic surgical skills are frequently taught to surgical interns in simulation centers. Faculty recruitment for teaching of these sessions can be difficult. The goal of this study was to determine whether senior surgical residents can effectively teach basic surgical skills to provide an alternative to faculty-led instruction. DESIGN, SETTING, AND PARTICIPANTS Academic medical cente...

Inherent difficulties in evaluating clinical competence of physicians has lead to the widespread use of subjective skill assessment techniques. Inspired by an analogy between medical procedure and spoken language, proven modeling methods in the field of speech recognition were adapted for use as objective skill assessment techniques. A generalized methodology using Markov Models (MM) was develo...

INTRODUCTION The ability to mentally rotate an object in 3 dimensions has been shown with an individual's score on the Vandenberg and Kuse Mental Rotations Test. The was to determine whether this Mental Rotations Test could be used to predict performance complex surgical skill - the tying of a 1-handed surgical reef knot. In addition, we learning a spatially complex surgical skill could be achi...

This is a presentation of sharing endeavors at modifying and standardizing surgical procedures as well as establishing endoscopic surgical skill qualification in the field of pediatric surgery in Japan.

We introduce skill chaining, a skill discovery method for reinforcement learning agents in continuous domains. Skill chaining produces chains of skills leading to an end-of-task reward. We demonstrate experimentally that skill chaining is able to create appropriate skills in a challenging continuous domain and that doing so results in performance gains.

Current concerns over reforming engineering education have focused attention on helping students develop skills and an adaptive expertise. Phenomenological guidelines for instruction along these lines can be understood as arising out of an emerging theory of thinking and learning built on results in the neural, cognitive, and behavioral sciences. We outline this framework and consider some of i...

OBJECTIVE The use of stereoscopic imaging can provide additional depth cues that may increase trainee performance on surgical tasks, but it has yet to be evaluated using a validated surgical skill system. This study examines the influence of monoscopic vs stereoscopic visualization in novice trainees performing the McGill Inanimate System for Training and Evaluation of Laparoscopic Skill (MISTE...
