2020 , Varela Aldas, José , Castillo Salazar, David Ricardo , Borja Galeas, Carlos , Guevara Maldonado, César Byron , Arias Flores, Hugo Patricio , Fierro-Saltos, W. , Rivera, R. , Hidalgo-Guijarro, J. , Yandún-Velasteguí, M.

Patients who lack upper and lower extremities have difficulties in carrying out their daily activities. The new technological advances have allowed the development of robotic applications to support people with disabilities, also, portable electroencephalographic (EEG) sensors are increasingly accessible and allow the development of new proposals which involve the mental control of electronic systems. This work presents the control by mental orders of an arm-hand prosthesis using low-cost devices, the objective is to command the arm using the user’s attention and blinking, where the components are a brain signal sensor, a prosthesis, an Arduino board, six servomotors, and a computer. The developed program in Matlab allows controlling the arm by means of an attention level y blinking. The results show the functioning of the system through experimental tests and a usability test is applied, finally, the conclusions establish adequate coordination in the movements of the prosthesis and the patient indicate satisfaction with the proposal. © Springer Nature Switzerland AG 2020.

2020 , Guevara Maldonado, César Byron , Hidalgo, J. , Yandún, M. , Arias Flores, Hugo Patricio , Zapata-Saavedra, L. , Ramirez-Morales, I. , Aguilar-Galvez, F. , Chalco-Torres, L. , Ortiz, D.P.

Cybersecurity in networks and computer systems is a very important research area for companies and institutions around the world. Therefore, safeguarding information is a fundamental objective, because data is the most valuable asset of a person or company. Users interacting with multiple systems generate a unique behavioral pattern for each person (called digital fingerprint). This behavior is compiled with the interactions between the user and the applications, websites, communication equipment (PCs, mobile phones, tablets, etc.). In this paper the analysis of eight users with computers with a UNIX operating system, who have performed their tasks in a period of 2 years, is detailed. This data is the history of use in Shell sessions, which are sorted by date and token. With this information a mathematical model of intrusion detection based on time series behaviors is generated. To generate this model a data pre-processing is necessary, which it generates user sessions (Equation presented), where u identifies the user and m the number of sessions the user u has made. Each session (Equation presented) contains a sequence of execution of commands (Equation presented), that is (Equation presented), where n is the position in wich the C command was executed. Only 17 commands have been selected, which are the most used by each user u. In the creation of the mathematical model we apply the page Rank algorithm [1], the same that within a command execution session (Equation presented), determines which command (Equation presented) calls another command (Equation presented), and determines which command is the most executed. For this study we will perform a model with sb subsequences of two commands, (Equation presented), where the algorithm is applied and we obtain a probability of execution per command defined by (Equation presented). Finally, a profile is generated for each of the users as a signal in time series, where maximum and minimum normal behavior is obtained. If any behavior is outside those ranges, it is determined as intrusive behavior, with a detection probability value. Otherwise, it is determined that the behavior is normal and can continue executing commands in a normal way. The results obtained in this model have shown that the proposal is quite effective in the testing phase, with an accuracy rate greater than 90% and a false positive rate of less than 4%. This shows that our model is effective and adaptable to the dynamic behavior of the user. On the other hand, a variability in the execution of user commands has been found to be quite high in periods of short time, but the proposed algorithm tends to adapt quite optimally. © Springer Nature Switzerland AG 2020.

Profiling of E-Learning Users with Accessibility Needs

2021 , Calle-Jimenez T. , Sanchez-Gordon S. , Arias Flores, Hugo Patricio

Currently, there are millions of people who are studying professional training using e-Learning environments. A trend that has been exacerbated by the global health crisis caused by the COVID-19 virus pandemic. This circumstance has forced students around the world to switch to an emerging online modality in 2020. E-Learning environments has become an important option, maybe the only one, to keep studying, as long as these environments and the educational resources they host are accessible. In this context, it is relevant to have a mechanism to describe the accessibility preferences and need of students through the management of personal profiles. In this study, authors carried out a literature review regarding models designed to enable the creation of profiles in the Massive Open Online Courses (MOOCs) and presents an analysis of scientific research published by other researchers and shows the current state of the art of the research area of profiling of students with disabilities in MOOC platforms. This literature review will serve as input to propose a model that allows covering the lack of profiling of students with disabilities within e-Learning platforms to meet the needs of students who have disabilities. As far as we know, this is the first literature review of this kind. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Adoption of Technological Products and Services in an Ecuadorian University for External Consumers

2021 , Palacio-Fierro A. , Arias Flores, Hugo Patricio

This article describes the experiences, initiatives and advances in disability issues for external consumers at a university in Ecuador, which has promoted collaboration agreements with various institutions. This synergy has allowed technological solutions to be developed in the field of disability. These include software for blind students, an augmentative communication board app for people with hearing disabilities, a telerehabilitation platform using the Kinect sensor for those with physical disabilities, a literacy kit with tangible interfaces and RFID sensors. Also, an inclusive board for people with intellectual disabilities which integrates Braille code, QR codes and augmented reality. These technologies have transcended academic frontiers and today, thanks to projects of connection with society, they support a vulnerable and traditionally forgotten population. In terms of educational inclusion, figures and initiatives that the university carries out through its Academic Department and Research Institute are presented. In the workplace, the institution developed a MOOC platform to raise awareness on the treatment of people with disabilities, through which nearly 800,000 public sector workers have been trained. Thanks to all these technological initiatives, a teleworking proposal was generated, which is still in development to connect people with disabilities and companies in carrying out intellectual tasks through a technological platform. The result of all these initiatives has left gratifying experiences and increasingly higher challenges in favor of educational and labor inclusion, especially of people with disabilities where there are more barriers in society than due to their abilities. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Value Proposal: A Participatory Brand Construction Model

2023 , Borja Galeas, Carlos , Arias Flores, Hugo Patricio

The brand is not only from the Unagotion, goes further, it is as if the consumer inner-Izara the product or service. It is searching from consistency, preubey, pursuit, trust, content, and reaching the client, and these elements are the way for the construction of the brand. The corporate image is created from a cultural internalization of management and will be reflected in the identity that will be reflected toward the whole world, and this design is born from the participation of the designer and the senior executives, who transform the ideas through the use of tools innovative The objective of this research is to generate a model that integrates the use of the business model canvas and participatory design, identifying the value proposition of the company. By using a heuristic matrix, which plasma the differentiating elements of the company, iconic elements represent them, together with the colors and typographies that together build the brand with its components: (1) morphology, (2) color, and (3) typography. The participatory design of the actors at each stage accelerates the brand construction, the results are integrated into the best corporate identity, and resistors are avoided in their adoption. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Autonomous Learning Mediated by Digital Technology Processes in Higher Education: A Systematic Review

2020 , Fierro-Saltos W. , Sanz C. , Zangara A. , Guevara Maldonado, César Byron , Arias Flores, Hugo Patricio , Castillo Salazar, David Ricardo , Varela Aldas, José , Borja Galeas, Carlos , Rivera R. , Hidalgo-Guijarro J. , Yandún-Velasteguí M.

The concept of autonomous learning has been resignified in recent years as a result of the expansion of the different types of study. Online education in higher education institutions has become an effective option to increase and diversify opportunities for access and learning, however, high rates of dropout, reprisal and low averages still persist. academic performance. Recent research shows that the problem is accentuated because most students have difficulty self-regulating their own learning process autonomously. From this perspective, the purpose of the study was to examine and analyze, through a systematic review of the literature, on autonomous/self-regulated learning, theoretical models and determine which variables influence a learning process mediated by technology processes in the higher education. The findings indicate that: (1) autonomous learning is a synonym of self-regulation; (2) Pintrich’s self-regulatory model is the most used in digital contexts; and (3) the self-regulatory variables identified are wide and varied. © Springer Nature Switzerland AG 2020.

Digital Resources and Children’s Learning: Parental Perception During the Pandemic

2021 , Alvites-Huamaní C. , Arias Flores, Hugo Patricio , Jadán Guerrero, Janio , Acosta-Vargas P.

The coronavirus disease (COVID-19) pandemic has disrupted family life around the world. Families had to adapt to teleworking and online learning to maintain young children’s learning at home. During quarantine and nationwide school closures, parents of young children and children with disabilities had to act as teachers, therapists and caregivers. The role of parents gained relevance and it was needed to be able to guide their children to use technology during online learning. Digital resources provided an opportunity for children to keep learning, take part in games and keep in touch with their friends and teachers. But it increased access online brings heightened risks for children’s safety, protection and privacy, so it is necessary that parents observe their children and support them. In this context, this paper presents the perception from parents about on the use of digital resources and techno-logical tools that teachers applied before and during pandemic. This study surveyed 773 Peruvian parents to know which of the resources used by teachers helped their children to understand the content of the course and which of tools allowed a better interaction with their classmates and teachers. According to the results of the survey, the most used resource before pandemic has been WhatsApp (32.1%), followed by office tools (Word or Excel 20.3%) and email (8.7%). However, for carrying out online activities during the pandemic the most digital used resource by the teachers has been WhatsApp (29.9%), then YouTube (17.6%), Google Drive (16.7%) and Google Docs. (7.9%). Regarding to a good interaction to increase a better interaction between their classmates and teacher were Zoom (61.7%), Google Meet (25.1%) and WhatsApp (11.6%). These results suggested that the use of digital resources and technological tools during the pandemic has been problematic and challenging for families. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
