The Evolution of Blockchain Virtual Machine Architecture Towards an Enterprise Usage Perspective
2019
Virtualization in the context of blockchain systems represents an essential phase in the development and migration of services from public chains to enterprise logic. Most of the ongoing blockchain uses-cases are using the existing public ledgers, but for business products and services, there is a need for custom tailored solutions to ensure flexibility and security. The Ethereum Virtual Machine has opened new ways to solve problems that require a public proof by executing logic on a decentralized ecosystem. In a natural evolutive process, virtualization logic was shaped by numerous architectures and business requirements. Beside performance and scalability, enterprise virtual machines are …
File system scalability with highly decentralized metadata on independent storage devices
2016
This paper discusses using hard drives that integrate a key-value interface and network access in the actual drive hardware (Kinetic storage platform) to supply file system functionality in a large scale environment. Taking advantage of higher-level functionality to handle metadata on the drives themselves, a serverless system architecture is proposed. Skipping path component traversal during the lookup operation is the key technique discussed in this paper to avoid performance degradation with highly decentralized metadata. Scalability implications are reviewed based on a fuse file system implementation. Peer Reviewed
Pseudo-haptic Controls for Mid-air Finger-based Menu Interaction
2019
Virtual Reality (VR) is more accessible than ever these days. While topics like performance, motion sickness and presence are well investigated, basic topics as VR User Interfaces (UIs) for menu control are lagging far behind. A major issue is the absence of haptic feedback and naturalness, especially when considering mid-air finger-based interaction in VR, when "grabbable" controllers are not available. In this work, we present and compare the following two visual approaches to mid-air finger-based menu control in VR environments: a planar UI similar to common 2D desktop UIs, and a pseudo-haptic UI based on physical metaphors. The results show that the pseudo-haptic UI performs better in t…
Serious Games to Teach Nutrition Education to Children Between 9 to 12 Years Old. Pickit! and Cookit!
2016
The current trend of increase in children obesity is worrying governments around the world and urgent actions are requested. The promotion of Nutrition Education in early stages has shown to be a factor to prevent the gain of weight in children. A tool that is gaining popularity in teaching contents to children are the Serious Games. The objective of this paper is to describe two Serious Games, Pickit! and Cookit! that has as objective to teach Nutrition Education to children between 9 to 12 years old. These games form part of the Modifying Eating and Attitudes through Learning platform, a pedagogical tool created for nutritionists and primary school teachers to transfer nutritional knowled…

Uso de la Realidad Virtual en Educación: un análisis bibliométrico
2022
Virtual Reality includes different technologies through which a user can experience a virtual world created in 3 dimensions by computer. Although its adoption has been slow, since the devices required to access virtual reality were expensive, there have been experiences in education since the 1990s. The present study carries out a bibliometric study in which 1074 articles related to the use of virtual reality in education from 1990 to the beginning of 2021 have been analyzed. It has been studied, from a quantitative point of view, the evolution of the annual scientific production, collaboration and production of authors, nationalities and sources of the articles. An analysis of citations, c…
Simulación clínica en pediatría y neonatología: adaptación telemática del proyecto de innovación educativa
2021
[EN] Introduction: Framed within an educational innovation project in the nursing degree, we introduce the application of realistic scenarios, generated through the EDISON tool to deal with topics such as pediatric and neonatal CPR. Due to the COVID-19 pandemic, an adaptation of the project to the telematic modality was proposed. Methodology: Analytical exploratory study where the effectiveness of a training intervention in a confinement context was evaluated. It was based on the use of audiovisual materials created through EDISON that configured a VideoBook that was made available to students through the Virtual Platform, evaluating its effectiveness through the final exam of the subject. …
La motivación de las tareas digitales mediante “pseudo-ApS” en Biología Celular del grado de Medicina
2020
[ES] Los grupos tutorizados de la asignatura “Biología” de 1º de Medicina (Universitat de València) son un entorno estupendo en el que desarrollas actividades que aúnen el carácter formativo conceptual con el desarrollo competencial transversal. Para ello, en el curso 19-20, hemos implementado la vinculación de la cuenta institucional UV con Microsoft 365, gracias al convenio existente entre ambas entidades para facilitar la utilización de las Tecnologías de la Información y la Comunicación (TICs) en la gestión del tiempo y del intercambio de información. Se propone a los alumnos la elaboración de objetos de aprendizaje propios y originales, en formato animación, que serán utilizados durant…
Virtual learning environment and academic outcomes: Empirical evidence for the teaching of Management Accounting
2014
ResumenEl objetivo fundamental de este trabajo consiste en contrastar empíricamente si el uso de un entorno virtual de aprendizaje (EVA) afecta positivamente a los resultados académicos de los estudiantes. El EVA desarrollado ha sido aplicado en la asignatura Contabilidad de Gestión, del Grado en Finanzas y Contabilidad de la Universitad de València. Esta experiencia de innovación docente, fundamentada en la teoría constructivista, combina diversos objetos de aprendizaje en el contexto de la plataforma Moodle. Su diseño implica un incremento de la motivación, el interés y la autogestión del aprendizaje de los estudiantes, al mismo tiempo que proporciona al profesorado instrumentos para eval…
Actualización y adaptación a la docencia híbrida de la asignatura Documentación y Metodología Científica del Grado en Farmacia
2021
[EN] The concern of the teaching staff to improve the teaching quality of the Scientific Documentation and Methodology subject that is taught in the first year of the Degree in Pharmacy (and double degree in Pharmacy and Human Nutrition and Dietetics) at the University of Valencia has been permanent with the development of three innovation projects during three consecutive courses and the creation of the Manual Documentation and Methodology in Health Sciences. The innovation generated includes the reformulation of both the content and the teaching methodology of the subject, based on the Flipped Classroom modality and focusing the contents around the construction of a monographic work by th…
