Analysis and improvement of the usability of a tele-rehabilitation platform for hip surgery patients

2019 , Pilco H. , Sanchez-Gordon S. , Calle-Jimenez T. , Rybarczyk Y. , Jadán Guerrero, Janio , Villarreal S. , Esparza W. , Acosta-Vargas P. , Guevara C. , Nunes I.L.

The Tele-Rehabilitation platform for hip surgery allows patients to carry out part of their rehabilitation at home, without the need to travel long distances to a rehabilitation centre. A lack of usability that may prevent effectiveness, efficiency, and the satisfaction of patients, may lead to problems of confusion, error and delay, or even abandonment of the physical therapy. To perform the usability analysis, a set of heuristics were selected relating to aspects such as navigation, visual clarity, coherence, prevention of errors, user guidance, online help and user control. A cognitive walkthrough technique was also applied. With the results of the analysis, the design and implementation of improvements were performed. The web interfaces of the Tele-Rehabilitation platform were evaluated once again and compared with the baseline to ensure there was an improvement in usability. © Springer International Publishing AG, part of Springer Nature 2019.

2018 , Ramos Galarza, Carlos , Acosta-Rodas P. , Jadán Guerrero, Janio , Guevara-Maldonado C.B. , Zapata-Rodríguez M. , Apolo-Buenaño D.

Introduction: The symbol digit modality test is a reactive which provides great support in neuropsychological evaluation. Its execution permits to evaluate brain functions such as visual perception, stimuli recognition, attention (focal, selective and sustained), task supervision, interference control among others. Object: The purpose of the current research study was to analyze the normative percentiles of the execution of the test, to identify the performance activity of the reactive according to age group and gender; applying the test in a sample of college students. Method: The sample included 250 university students,142 (56.8%) males and 108 (43.2%) females. The age range of the participants was between 18 and 34 years old (M=21.53, DE=2.25). A transversal, non-experimental, quantitative research model with a correlational scope was used. Results: The correct answer average for the test was 52.83 (DE=13,60) and for percentile P5 31,55 right answers were found; for percentile P75 60,00 right answers, P25 had 46,00 right answers, and for P95 74,45 right answers were found. No significant differences were found for the mean of errors in the test in terms of age group f(3, 246)=0,67, p=0,57 and gender t(248)=0,68, p=0,49 of the participants as comparison factor. Conclusions: Results were discussed based on prior research pointing out the importance of counting with a first statistical parameter of the test as ground for neuropsychological clinical practice in Ecuador. © 2018 Fundacion para la difusion neurologica en Ecuador - FUNDINE.

Fostering Business Education Using Playful and STEAM Pedagogy

2022 , Sigcho N. , Jadán Guerrero, Janio

STEAM educates children in science, technology, engineering, art, and mathematics fields with an interdisciplinary approach, leading from an early age to adapt to an ever-changing world. This research proposes the use of recyclable materials that exist at home to create domestic laboratories for the development of scientific thinking that support the resolution of problems in daily life. The research methodology was based on data collection from 9 teachers and 130 eighth-year high school students. For data collection, a questionnaire on logical reasoning was applied, which evaluated the ability of students to respond to everyday situations and teachers were surveyed to find out if they use technological educational resources in classrooms. With the results obtained, it is proposed to develop: “Instruments for domestic laboratories.” The results aroused great interest in teachers and students when conducting a satisfaction survey, in which a high degree of motivation and interaction with the resources developed was obtained. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

A Case Study: Developing reusable Learning Objects

2021 , Santorum M. , Carrion-Toro M. , Guacapina M.-B. , Acosta-Vargas P. , Jadán Guerrero, Janio

Information and Communication Technologies (ICT) offer the possibility of creating a massive resource and knowledge base in the educational field. Learning Objects (LOs) are digital instructional elements that help users' complete tasks. This diversity has made it difficult to easily integrate them into educational software solutions, which is why this document presents a study of the characteristics, standards, and tools for creating and reusing OAs. For this purpose, a systematic literature review of 1023 scientific articles were carried out. With the results of 42 selected articles, a website was developed based on the SCRUM methodology, which integrates OAs oriented to the use of ICT tools to contribute to virtual education generated by the global crisis of the pandemic by the COVID-19. This study can serve as an input in future studies related to SCRUM-based learning objects. © 2021 IEEE.

Improve Accessibility and Visibility of Selected University Websites

2020 , Acosta-Vargas P. , Ramos Galarza, Carlos , Salvador-Ullauri L. , Chanchí G.E. , Jadán Guerrero, Janio

Currently, there are millions of websites, but not all of them are accessible and visible in search engines, and in the different devices and technologies used. The purpose of this research is to 1) suggest an accessibility evaluation model according to the Web Content Accessibility Guidelines 2.1 standards; 2) correlate Webometrics and SCImago rankings to improve visibility, and 3) determine whether an accessible website can improve visibility. As a case study, the authors applied to 30 web pages from Latin American universities. The results indicate that although an educational institution is in the first rankings of the Webometrics and SCImago classification, they do not necessarily satisfy web accessibility requirements. This study can be a guide for the definition of institutional efforts to improve accessibility and visibility in the design of more inclusive and visible websites. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.

3D Object Reconstruction Using Concatenated Matrices with MS Kinect: A Contribution to Interiors Architecture

2020 , Buele, Jorge , Varela Aldas, José , Castellanos E.X. , Jadán Guerrero, Janio , Barberán J.

Interior architecture is part of the individual, social and business life of the human being; it allows structuring the spaces to inhabit, study or work. This document presents the design and implementation of a system that allows the three-dimensional reconstruction of objects with a reduced economic investment. The image acquisition process and treatment of the information with mathematical support that it entails are described. The system involves an MS Kinect as a tool to create a radar that operates with the structured light principle to capture objects at a distance of less than 2 meters. The development of the scripts is done in the MATLAB software and in the same way the graphical interface that is presented to the user. As part of the initial tests of this prototype, the digitization of geometric shape structures has been performed with an accuracy of over 98%. This validates its efficient operation, which serves as the basis for the development of modeling in interior architecture for future work. © 2020, Springer Nature Switzerland AG.

Nowadays, there is a rapid technological progress around the world that has enabled realities long ago unimaginable. We live in a technological era that represents new possibilities and challenges for society, and for the educational models in each country [1]. Research on smart education, which has forced the educational community to rethink on new ways of learning and teaching has been developed globally. Due to the advent of artificial intelligence (AI), the educational model for both, teachers and students will change. Nevertheless, to transform educational systems, it is necessary to update and train students, educators, and administrators effectively [2]. This research aims to describe the possible applications of AI in education from: 1) the automation of administrative tasks; 2) collection and analysis of information [3] to create smart content; 3) the implementation of virtual assistants in the teaching-learning process; 4) the potential delivery of lectures by humanoid robots with AI. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

2022 , Santos-Tiberio H. , Vinueza A. , Jadán Guerrero, Janio

This new era of software development began to generate changes in the way software development teams are organized, new roles and functions are established in project management. In many cases this role does not exist and a similar role must be chosen and the project manager must adapt. This research seeks to know the changes made by software project managers in private companies in Guatemala City. The research hypothesizes that the implementation of agile methodologies produces an update in the functions and roles in the area of project management in private institutions. For this purpose, a four-phase study was carried out: Design of the instrument, Distribution of the instrument, Processing of the information and Analysis of the information. A sample of 35 private companies was worked with the participation of software development team leaders. The results obtained from an online survey allowed us to discover that there are considerable changes in the roles and responsibilities of project leaders in organizations that migrate from traditional methodology to agile methodology. © 2022 IEEE.

2016 , Jadán Guerrero, Janio , Guerrerob L.A. , Sharmac T.

Interactive systems aimed at educational environments are becoming increasingly important in students learning. This paper focuses on the application of Radio Frequency (RFID) technology in early literacy process of Down syndrome students. An experimental study was carried out in Costa Rica among four special education teachers and six Down syndrome students of a Special Education School. The research aimed to measure the interaction between participants and three user interfaces: traditional interface based on cardboard cards, Graphic User Interface (GUI) based on digital cards and Tangible User Interface (TUI) based on 3D letters and low cost toys with RFID tags. The method consisted of the registration of occurrences in the behavior of participants. The results obtained from the application of the Friedman test confirmed the exploratory findings carried out in a qualitative previous work, in which TUI improves the interaction in early literacy process of Down syndrome students. © 2016 IEEE.
