background: video-based instruction has been stated as an effective method of teaching and its potentials have encouraged instructors learners to opt this method purpose: the current study has compared the students' cognitive learning in the two approaches of lecture- based and video-based teaching. methods: this quasi-experimental study was conducted on 88 senior nursing students who were rand...

BACKGROUND Discrimination between neoplastic and non-neoplastic lesions is crucial in colorectal cancer screening. Application of narrow-band imaging (NBI) in colonoscopy visualises mucosal vascular networks in neoplastic lesions and may improve diagnostic accuracy. AIM To compare the diagnostic efficacy of NBI in differentiating neoplastic from non-neoplastic colorectal lesions with diagnost...

The extension of Phase-based Video Motion Magnification into three-dimensions is presented in this work. technique uses a 3D complex steerable pyramid to decompose volumetric frames 4D dataset. resulting decomposition can be processed filter, amplify, or attenuate subtle motions occurring locally within the data, before inversion transform performed recreate images. Recent research has used Pha...

Background: Loupes represent a type of magnification and their use can promote higher quality on dental treatment. Besides those advantages magnification can be beneficial for musculoskeletal health maintenance on dental professionals. Aim: This study intends to review the literature in order to verify what has been studied regarding the influence of magnification on work posture of dentists. M...

We describe a method for deriving the linear cortical magnification factor from positional error across the visual field. We compared magnification obtained from this method between normally sighted individuals and amblyopic individuals, who receive atypical visual input during development. The cortical magnification factor was derived for each subject from positional error at 32 locations in t...
