Augmented Reality, Virtual Reality and Mixed Reality in Medical Education: A Comparative Web of Science Scoping Review

Background: Since the advent of virtual reality (VR), it has been used in medical education for surgical training and anatomy teaching. Recently, other modalities of extended reality (XR) such as augmented reality (AR) and mixed reality (MR) has also made its way into medical education. Although there has been research validating XR’s use in medical education, there have been few studies on the research trends of the different XR modalities. The paper aims to compare the research trends of the XR modalities in general and in terms of the medical fields studied and outcomes measured. Methods: Web of Science was searched, and preliminary data was extracted to analyze the general trend. Inclusion and exclusion criteria were then applied, and finalized articles were analyzed and grouped based on the medical field studied and outcomes measured. Results: 31 articles on VR, eight on AR and one on MR were included in the final analysis. We found that there is increasing research in VR since 1990 and AR since 2008. The research in MR is constant. Most of the papers on VR studied endoscopic surgery and anatomy whereas AR studied mostly anatomy and endovascular procedures. Using Miller’s prism of clinical competence, the competency measured most for VR and AR is “show”. Discussion and conclusion: Advancement in computing, communication and display technologies since 1990 may contribute to the increase in research on VR whereas the ubiquity of smartphone since 2008 may explain the increase in research on AR. Although both VR and AR are used in surgical training and anatomy teaching, we found possible strengths of VR in counseling and AR in practical skills. The competency "show" was measured most as most of the papers were on surgery, and the XR simulators used can capture surgical parameters
La medida de la dosis de diálisis mediante Kt por dialisancia iónica revela una menor adecuación que la medida por Kt/VUREA en la insificiencia renal aguda de pacientes críticos

Introduccion: La medida de la dosis de hemodialisis basada en la cinetica de la urea (Kt/VUREA) adolece de problemas de aplicabilidad en el paciente critico con insuficiencia renal aguda (IRA). No obstante, las recomendaciones de consenso sobre la dosis se basan en el Kt/VUREA. Objetivo: Evaluar la utilidad de la medida en tiempo real de la dosis de dialisis suministrada (Kt) mediante dialisancia ionica (KtDI) en el paciente critico y el grado de adecuacion de la dosis en comparacion con la medida estandar del Kt/VUREA. Material y metodos: Estudio prospectivo observacional de medida de dosis en 17 pacientes criticos con IRA sometidos a 3 sesiones de dialisis intermitente con prescripcion predefinida para este estudio (en total 51 medidas). Resultados: El Kt/VUREA medio suministrado por sesion fue de 1,19 ± 0,14, con un 59% de sesiones consideradas adecuadas por lo recomendado por la ADQI. Por el contrario, la media de KtDI obtenida fue de 37,6 ± 1 l, con solo un 29,4% igual o por encima del valor minimo recomendado. Conclusiones: La monitorizacion de la dosis mediante KtDIrevela un menor grado de adecuacion en comparacion con el Kt/VUREA. El caracter dinamico de la medida de KtDI puede permitir la adaptacion de cada sesion de dialisis («K» y/o «t») con el fin de lograr el objetivo de dosis minima.
Height model generation, automatic geocoding and a mosaicing using airborne AeS-1 InSAR data

The goal of this paper is to present the generation of high resolution digital surface models using airborne AeS-1 interferometric SAR data, their automatic geocoding and mosaicing. In order to be able to carry out these steps, high precision differential Global Positioning System data, high frequency attitude data of the platform, exact time synchronization and range delay of the system must be known. Since in the airborne case motion instabilities are large, due to dynamic properties of the aircraft and atmospheric turbulences, precise motion measurements of the platform are extracted and considered during the SAR processing. Once that all these basic requirements are fulfilled, one is able, using the processing reference tracks, and exploiting a forward-backward geocoding, to convert the phase differences to elevation data and to geolocate them by taking into account all geodetic and cartographic transforms. Results based on 400 MHz X-band InSAR data show that the derived surface model has a positioning accuracy in the order of 0.5 m and a height accuracy better than 0.3 m.

A Framework for the Acquisition, Processing and Interactive Display of High Quality 3D Models

This tutorial highlights some recent results on the acquisition and interactive display of high quality 3D models. For further use in photorealistic rendering or object recognition, a high quality representation must capture two different things: the shape of the model represented as a geometric description of its surface and on the other hand the appearance of the material or materials it is made of, e.g. the object’s color, texture, or reflection properties. The tutorial shows how computer vision and computer graphics techniques can be seamlessly integrated into a single framework for the acquisition, processing, and interactive display of high quality 3D models.
Heuristic evaluation of e‐learning courses: a comparative analysis of two e‐learning heuristic sets

Purpose – The purpose of this paper is to discuss heuristic evaluation as a method for evaluating e‐learning courses and applications and more specifically to investigate the applicability and empirical use of two customized e‐learning heuristic protocols.Design/methodology/approach – Two representative e‐learning heuristic protocols were chosen for the comparative analysis. These protocols augment the “traditional” heuristic sets so as to cover technology‐enhanced learning properties. Two reviewers that have considerable experience in usability evaluation as well as in e‐learning were involved in this comparative analysis. Coverage, distribution and redundancy were employed as three basic criteria for conducting the evaluationFindings – The main results of the study indicate that both heuristic protocols exhibit wide coverage of potential usability problems. The distribution of usability problems is uneven to a large number of heuristics for both heuristic sets, which reveals that some heuristics are mor.

Resolving depth-measurement ambiguity with commercially available range imaging cameras

Time-of-flight range imaging is typically performed with the amplitude modulated continuous wave method. This involves illuminating a scene with amplitude modulated light. Reflected light from the scene is received by the sensor with the range to the scene encoded as a phase delay of the modulation envelope. Due to the cyclic nature of phase, an ambiguity in the measured range occurs every half wavelength in distance, thereby limiting the maximum useable range of the camera. This paper proposes a procedure to resolve depth ambiguity using software post processing. First, the range data is processed to segment the scene into separate objects. The average intensity of each object can then be used to determine which pixels are beyond the non-ambiguous range. The results demonstrate that depth ambiguity can be resolved for various scenes using only the available depth and intensity information. This proposed method reduces the sensitivity to objects with very high and very low reflectance, normally a key problem with basic threshold approaches. This approach is very flexible as it can be used with any range imaging camera. Furthermore, capture time is not extended, keeping the artifacts caused by moving objects at a minimum. This makes it suitable for applications such as robot vision where the camera may be moving during captures. The key limitation of the method is its inability to distinguish between two overlapping objects that are separated by a distance of exactly one non-ambiguous range. Overall the reliability of this method is higher than the basic threshold approach, but not as high as the multiple frequency method of resolving ambiguity.
Convention e-Brief Speech Intelligibility Advantages using an Acoustic Beamformer Display

A speech intelligibility test conforming to the Modified Rhyme Test of ANSI S3.2 "Method for Measuring the Intelligibility of Speech Over Communication Systems" was conducted using a prototype 12-channel acoustic beamformer system. The target speech material (signal) was identified against speech babble (noise), with calculated signal-noise ratios of 0, 5 and 10 dB. The signal was delivered at a fixed beam orientation of 135 deg (re 90 deg as the frontal direction of the array) and the noise at 135 deg (co-located) and 0 deg (separated). A significant improvement in intelligibility from 57% to 73% was found for spatial separation for the same signal-noise ratio (0 dB). Significant effects for improved intelligibility due to spatial separation were also found for higher signal-noise ratios (5 and 10 dB).
Compromis performance/sécurité des passerelles très haut débit pour Internet. (Performance/security trade-off for high-bandwidth Internet VPN gateways.)

Dans cette these nous abordons le probleme de la conception de passerelle IPsec tres haut debit pour la securisation des communications entre reseaux locaux. Pour cela, nous proposons deux architectures : une passerelle purement logicielle sur un unique serveur, dite integree, et une passerelle utilisant plusieurs serveurs et un module materiel cryptographique, dite en rupture. La premiere partie de nos travaux etudie l'aspect performance des deux architectures proposees. Nous commencons par montrer qu'un serveur sur etagere est limite par sa puissance de calcul pour atteindre l'objectif de chiffrement et communication a 10 Gb/s. De plus, les nouvelles cartes graphiques, bien que prometteuses en terme de puissance, ne sont pas adaptees au probleme du chiffrement de paquets reseau (a cause de leur faible taille). Nous mettons alors en place une pile reseau repartie sur plusieurs machines et procedons a sa parallelisation dans le cadre de l'architecture en rupture. Dans un second temps, nous analysons l'integration d'une passerelle dans un reseau, notamment l'interaction du protocole de controle ICMP avec IPsec. ICMP est particulierement important pour atteindre de haut debit par son implication dans le mecanisme d'optimisation de la taille des paquets. Pour cela, nous avons developpe IBTrack, un logiciel d'etude du comportement des routeurs, par rapport a ICMP, le long d'un chemin. Nous montrons ensuite qu'ICMP est un vecteur d'attaque contre IPsec en exploitant un defaut fondamental des normes IP et IPsec : le surcout des paquets IP cree par le mode tunnel entre en conflit avec le minimum de la taille maximale prevue par IP.
School-based emergency intervention following an Adolescent's suicide

Abstract This paper describes a brief (3 days) school-based intervention following a student's suicide. Primary and first-aid crisis intervention was aimed at (a) organizational guidelines for the school administration in response to the immediate emergency and (b) principal steps for dealing with the stress reaction of the deceased's peers. Preliminary data were obtained on 10th graders' (classmates and another class) frequencies of stress reaction a day following the suicide.
Textile Performance Assessment for Smart T-Shirt Development

This paper discusses a methodological approach for the metrological characterization of features in conductive textile. One of the outcomes of this paper is an integrated testing protocol aiming to assess the mechanical and electrical specification of conductive fabric. The protocol has been developed focusing on smart garments; this allows for evaluating the conductive features over elasticity, moisture, temperature and washing. The fine characterization of the fabrics allows to use them both as electrodes, sensors or wired connections. In particular, the paper studies the metrological aspects of conductive textile in order to optimize and verify their usage in sensorized t-shirt (as ECGElectro-CardioGram electrodes, strain gauge, etc.) for continuous non-invasive monitoring in hospital settings, activity of daily living (ADL), sports and fitness. This study looks at optimizing the conductivity of the yarn that follows in minimizing the movement artifacts; this could increase the general performances and reliability of smart garments. Keywords-component; conductive yarn characterization, textile sensors, smart t-shirt.
Essential Tremor: A Comprehensive Overview

Essential tremor is the most prevalent form of movement disorders in the world and is 10 times more prevalent than that of Parkinson’s disease. Even though it is traditionally considered as a benign disease all the patients of essential tremor have tremor induced disabilities. Essential tremor which shows kinetic, postural and resting is tremor mimicker of all tremor associated disease so often misdiagnosed and mismanaged. This article is authors’ endeavor to summarize the facts in different publications on essential tremor. Electronic databases like MEDLINE/Pub Med, Google Scholar, IMSEAR (Index Medicus for South-East Asia Region) and Scopemed were extensively searched with MeSH (Medical Subject Headings) terms “essential tremor”, “clinical features” “pathophysiology” and “treatment” from the earliest possible date of 1966 to Feb 2017. Articles in any languages especially those published in recent years were given preference. This review deals mostly with the clinical features and evidence-based management of essential tremor.
A Novel Multi-keyword Ranked Search System In encrypted and Synonym Queries supported Cloud

an enhancement we enhance the existing system and we propose the effective approach to solve the problem of multi keyword ranked search over encrypted cloud data synonym queries. The main contribution of summarized in two aspects: multi-keyword ranked search to achieve more accurate search results and synonym-based search to the support synonym queries. Meanwhile, existing search approaches over encrypted cloud data support only exact the fuzzy keyword ranked search, therefore, how to enable an effective searchable system with support of ranked search remains a very challenging the problem, but not semantics-based multi-keyword ranked search.
Effect of Interferon-α2b Therapy on St. Louis Viral Meningoencephalitis: Clinical and Laboratory Results of a Pilot Study

The safety and potential efficacy of interferon (IFN)-alpha2b were determined for 15 patients during an outbreak of meningoencephalitis due to St. Louis encephalitis (SLE) virus. Clinical and laboratory results were compared with those of 17 untreated patients who were admitted to the same hospital during this nonrandomized preliminary trial. Quadriplegia, quadriparesis, or respiratory insufficiency persisted after the first week of hospitalization, for 11 of 17 untreated patients and for only 2 of 15 treated patients. These complications existed after the second week of hospitalization for 5 of the 17 untreated patients and for 1 of the 15 treated patients. Transient neutropenia and/or mild hepatitis occurred in 11 treated patients. Early initiation of IFN-alpha2b therapy may reduce the severity and duration of complications due to previously untreatable flavivirus meningoencephalitis. A prospective randomized controlled trial is warranted.

Higher order aberrations and age-related cataract: a pre- and post- operative study

The outcome of higher order aberrations (HOAs) prior to, and following, age-related cataract extraction and intra-ocular lens (IOL) implantation was explored using placido disc skiaoscopy aberrometry. Ninety-nine individuals (median age 73.0, IQR 67.0, 80.5) underwent comprehensive ophthalmic examination including contrast sensitivity, endothelial cell imaging and aberrometry (Nidek OPD ARK-10000) at approximately 4 weeks pre-operatively (median 3.9, IQR 2.9, 4.8) 10 weeks (median 7.1, IQR 5.64, 11.71) (67 individuals) and 80 weeks (median 85.1, IQR 80.0, 89.6) (41 individuals) post-operatively. Linear relationships between thirteen demographical, functional and structural variables and each of three components, Total (TC), Corneal (CC) and Internal (IC), for each of eight HOAs, were separately explored, using Analysis of Variance, for each examination and for the pre- and post-operative differences, respectively. The TC and IC of all HOAs decreased post-operatively (p≤68%). Preoperatively, the TC and IC of the Total HOA decreased as the spherical equivalent (SE) became less negative (both p<0.001, R2=0.56 and 0.53). Both components of the Total HOA also decreased as the difference in SE between baseline and each follow-up became less negative (all p≤0.008, R2=0.45-0.61); the magnitude of the reduction varied between IOL type (p≤0.008). The IC of the Tilt, T.Sph and HiAstig HOAs increased with increase in severity of posterior subcapsular (p=0.018), of cortical (p=0.013) and of combined nuclear colour and cortical cataract (p=0.003), respectively. The relationship between cataract type and severity and reduction in post-operative HOA was not statistically significant at either follow-up examination. Slight associations, presumably due to post-operative corneal oedema, were present between increase in CCs of five HOAs and decreasing endothelial cell density at the first follow-up, only, (all p≤0.030, R2=0.09-0.14). Pre-operative TCs and ICs were larger, respectively, than those of 22 individuals with ‘less severe’ cataract and post-operatively than those of 49 individuals with clear media, obtained from retrospective data.

Meat is either consumed as a component of kitchen-style food preparations or as processed meat products. Processed meat products, although in some regions still in their infancy, are globally gaining ground in popularity and consumption volume. Meat processing has always been part of FAO's livestock programmes, not only because of the possibility of fabricating nutrient-rich products for human food, but also owing to the fact that meat processing can be a tool for fully utilizing edible carcass parts and for supplying shelf-stable meat products to areas where no cold chain exists. Moreover, small-scale meat processing can also be a source of income for rural populations. In the mid eighties to early nineties of the last century, FAO published two books on meat processing (Animal Production and Health Series No. 52 and 91) in order to familiarize food processors in developing countries with meat processing technologies. However, due to the time elapsed since then they no longer fully reflect current techniques and processing procedures used in the meat sector. FAO initiated two major projects in this sector. In the mid nineties and in early 2000, in cooperation with the Common Fund for Commodities (CFC) and the German Development Agency GTZ/CIM, FAO ran two comprehensive regional training and development projects on meat processing technology, the first one in sub-Saharan Africa and the second one in Asia. The experience gained in these two meat processing projects led to the decision that an updated manual on meat processing technology should …
An Algorithm on Web Article Automatic Extraction Based on DOM Structure

By analyzing a large number of web pages, we proposed a page segment algorithm which is based on DOM tree structural features and visual features. The algorithm segments the pages to the small particles. It produces basic processing units for recognition algorithms. After segmenting the pages, we extracted the structural and visual features of the pages, and proposed a method to identify the body of the web article. The method uses clustering algorithm and heuristic rules to produce an automatic wrapper. A testing experiment demonstrated the efficacy of the algorithm.
