(Springer Science and Business Media Deutschland GmbH, 2020) Cedillo Orellana, Irene Priscila; Valdez Solis, Wilson Fernando; Cárdenas Delgado, Paúl; Prado Cabrera, Katerine Daniela
Internet of Things (IoT) applications nowadays generate a large amount of data, which are continually requiring adequate treatment and services on the Cloud to be available to stakeholders. Healthcare applications manage critical data from different sources as patient charts, Electronic Health Record (EHR), and devices which need security levels, data formatting, and quality of data due to their importance and sensitivity. Data as a Service (DaaS) is a data management framework provided though services on Cloud to bring data storage, integration, processing, analysis services, security, availability, elasticity, and quality characteristics to the data concerning the stakeholders. In this context, this paper proposes a data management solution deployed as DaaS for the healthcare domain presented through a metamodel focused on the federation pattern of data based on an Extract-Transform-Load (ETL) model for data classification; and considering a brief analysis of the non-functional characteristics proper of the DaaS domain as the security, confidentiality, priority, and availability. The metamodel is validated through an instantiation process using the MOntreal Cognitive Assessment (MOCA) test as the entry. Finally, it is presented a discussion from four stakeholder perspectives (e.g., data engineer, IoT solution developer, data quality analyst, health professional) about the solution.

(Institute of Electrical and Electronics Engineers Inc., 2019) Valdez Solis, Wilson Fernando; Cedillo Orellana, Irene Priscila; Trujillo Orellana, Andrea Alexandra; Orellana Cordero, Marcos Patricio
The Internet of Things (IoT) is a current paradigm which can be part of several fields of application, and Healthcare is one of the most important. Ambient Assisted Living (AAL) is an important subfield in Healthcare. Also, services demand and network requirements of IoT systems due to the increase of connected devices and data flow overcharges Cloud. Fog Computing represents a new paradigm that lightens the network. Some applications use Fog Computing in order to reduce costs and improve performance of IoT applications. Healthcare is one of them and the implementation of Fog Computing architectures inside those systems is a new trend nowadays. The importance of having a data infrastructure in this kind of IoT systems is evident because of the relevance of the data. In this paper is presented a Data Infrastructure for Managing Information Obtained from Ambient Assisted Living. The model provides the data flow starting in the data reading in the IoT devices and ending in the Cloud by crossing Fog Computing Layer. The model considers communication protocols, security features and relationship between elements which take part in an AAL system. Moreover, the model was developed using Eclipse Modeling Tool and validated in the same tool by using an instantiation of the main classes of the model.

(Springer, 2020) Cedillo Orellana, Irene Priscila; Valdez Solis, Wilson Fernando; Córdova Cuenca, Andrés Fabricio
Accidents during elderly are one of the greatest geriatric syndromes due to the frequency with which they appear between patients. There are incidents that mark a milestone for acute and chronic deterioration in the health during old age. Among the instruments explored over time by the medical area in order to know the factors that lead to falls in elderly people, the Tinetti test is the most complete and validated measurement instrument. Tinetti is an observational scale that allows the evaluation by means of two sub-scales (i) the march (9 items) and (ii) the balance (13 items) in static position and when the patient is moving. Generally, this test is performed by specialized medical personnel (doctors or physiotherapists) and the acquisition of data used in each one of the items in this test is recorded manually. This paper presents the design and construction of an Assistive Technology Device, which supports medical personnel during the application of the balance sub-scale in the Tinetti test. This solution will consist of a carpet equipped with sensors that allows to know the position of the patient through heat maps and the body weight that is distributed in each area during the performance of the Tinetti test. In addition, it will allow the acquisition of data in a digital form, and since it is an object of the Internet of Things, it will allow the monitoring of the information coming from the test locally and remotely, as well as registering the information and making it available on the cloud. © Springer Nature Switzerland AG 2020

Assistive Technology (AT) maintains and improves the individual’s functioning and independence, thereby promoting their well-being. But today only 1 from each 10 people in need have access to AT due to high costs and a lack of awareness, availability, personal training, policy and financing. By 2050, more than 2 billion people will need at least 1 assistive product with many elderly needing 2 or more. Elderly make important contributions to the society. Though some people aged well, other become frail, with a high risk of disease. In this paper, we propose a first approach related the design of AT device. This uses open source technologies and gives a new choice in taking medication dosages. “The Intelligent PillBox” allows the organization of several medication schedules that health disorders presented in elderly need basically. Arduino Mega 2560 was took as the principal controller. This prototype contains; a programmable alarm system with an automatic opening and closing system, an interactive user interface and a notification system through GSM network. The development of this device is focused in the support of elderly people and other vulnerable groups that may need for an assisted care.

(Institute of Electrical and Electronics Engineers, 2021) Santos León, David Enrique; Maxi Jara, Kevin Alexander; Prado Cabrera, Katerine Daniela; Mora Aguirre, Brian Oswaldo; Valdez Solis, Wilson Fernando; Cedillo Orellana, Irene Priscila
To address problems related to people's memory, several techniques have been developed; one of them consists of cognitive training that seeks to maintain and improve the brain's essential executive functions. Today this technique has made use of software applications to provide such training. One way to support these applications' development is through Domain-Specific Languages (DSLs), which has reduced focus but produces an efficient solution. However, the applications' growth and complexity have generated systematic and specific approaches to evaluating the products developed. This study proposes to assess DSLs aimed at creating interactions for cognitive training. A quality model based on the ISO 25010 standard is presented with an evaluation method that references the ISO 25040 standard. The quality model focuses on Functional Suitability, while the evaluation method focuses on the Running the Assessment phase. The inputs generated were tested in an experimental environment. The results show that an effective, efficient, and satisfactory evaluation of DSLs within the domain can be developed from the generated quality and evaluation methods.
Evaluating the usability in domain-specific languages
(Universitat Politècnica de València, 2021) Moreira Jara, Christian Alexander; Cedillo Orellana, Irene Priscila; Sánchez Zhunio, Bertha Cristina; Valdez Solis, Wilson Fernando; Cobos Quinde, Juan Manuel
Domain-Specific Languages (DSL) represent software abstractions that provide semantic to a specific class or domain. DSLs use the concepts and rules from the field or domain to strengthen ties between the domain expert and the technology. Although several DSLs are modeled by considering quality features, most do not have high-quality characteristics related to their usability or do not address them. However, this characteristic constitutes a key aspect for software engineers and domain experts while designing their solutions. Therefore, this paper presents a usability quality model for DSLs aligned to the ISO / IEC 25010 standard and an evaluation model based on the ISO / IEC 25040 standard. Finally, the evaluation method was applied in order to show its feasibility by a case study that addresses the use of two DSLs (related to Ambient Assisted Living and Cloud Computing domain) and assesses their usability.

Math-odology: methodology for teaching mathematics and tools for the implementation of virtual classes
(2021) Bermeo Arpi, Alexandra Elizabeth; Cedillo Orellana, Irene Priscila; Valdez Solis, Wilson Fernando; Prado Cabrera, Katerine Daniela
Due to the COVID-19 pandemic that is affecting worldwide, the educational centers have been forced to change its regular classroom classes approach towards a virtual environment. This change has brought challenges and difficulties for teachers and students since this is a learning style that has not been used before for most of them. The area of Mathematics is a clear example of these challenges, since it is usually considered one of the most challenging subjects, and one that conventionally requires a classroom environment to be taught appropriately and pedagogically. Therefore, it is important to create a methodology for implementing virtual classes in Mathematics and also, search for tools to improve and enhance the learning process, while making it adaptable for the continuously changing learning environments. The proposed methodology is based on the study of pedagogical techniques, different Learning Management Systems (LMS), and online resources involved with the virtual teaching of Mathematics. To develop it, the Analysis Design Development Implementation Evaluation (ADDIE) method has been applied, while the illustration has been made using the Software Process Engineering Metamodel (SPEM), which allows developers and group members to adopt processes in a common language. This methodology was evaluated through a study case where a group of Mathematics university instructors were asked to apply the methodology in a class, while, another group was asked to impart a virtual class without it. Then, a questionnaire about their perceptions and expectations was applied to the students; and to the instructors about perceptions. Finally, after comparing the results it was concluded that Math-odology is highly applicable to adapt a mathematics class to a virtual environment. Also, it is necessary to link each activity with the right tools that contribute positively to the teaching-learning process.

(Springer Science and Business Media Deutschland GmbH, 2021) Cedillo Orellana, Irene Priscila; Galan Galan, Jorge Esteban
The devices are crucial elements in the Internet of Things (IoT) applications. The correct selection of these elements influences the quality, cost, and adequate addressing of the application depending on the needs in each of the IoT verticals. In this sense, the need for methodologies for selecting IoT devices is an exciting field to explore in research. Therefore, this paper presents a Systematic Literature Review (SLR) based on the Kitchenham and Charters methodology, as the first step for designing a methodology for the selection and acquisition of IoT devices oriented to older people. The presented SLR describes the existing methods, technical criteria, context criteria (e.g., contracts, government restrictions), and other elements considered for selecting IoT devices from 2010 to 2021 year; this from the review in digital libraries, conferences, and journals. Sixteen articles were found following the methodology of systematics review. The obtained results are made up of studies for the selection of IoT devices, or criteria for the selection of technology related to IoT, such as IoT services, IoT platforms, sensors for IoT devices, among others. Most of the found studies are not directed to a specific domain, except for a few directed to people in general or companies. Overall, the study evidences a gap in the selection methodologies for IoT devices in applications-oriented to the elderly and the presence of some context-related selection methods.

(IEEE, 2021) Galan Galan, Jorge Esteban; Cedillo Orellana, Irene Priscila; Valdez Solis, Wilson Fernando
uring old age, there is a deterioration of cognitive or physical functions that reduce the elderly's independence. At this stage, the person may need help with activities of daily living. Many products and several lines of research based on the Internet of Things (IoT) have been opened to improve or preserve the physical and cognitive condition of the elderly, which leads to the prolongation of their independence. Regarding selecting these devices, methods are needed to guide the solution architect so that, based on physical, medical, technical, and economic specifications and additional considerations related to the needs and possibilities of the person or their environment, they select the more suitable IoT solution. In this context, this study proposes a methodology for the selection and acquisition of IoT devices that intervene in environments to improve the quality of life of the elderly, based on the previously identified requirements that IoT devices must meet and the restrictions of the environment. The proposed methodology is based on the multi-criteria decision-making technique called the Analytical Hierarchy Process (AHP). Finally, a case study has been performed to demonstrate the feasibility of applying this solution.
Towards the Evaluation of the Performance Efficiency of Fog Computing Applications
(Springer, 2021) Barzallo Sagbay, Ana Lucia
Nowadays, Cloud Computing represents an effective solution for organizations that need to adopt a model of elastic computing services and pay-as-you-go. However, in new domains, such as Cyber-Physical Systems and the Internet of Things (IoT), which manage large volumes of data, the time of latency in communication between the Cloud server and users, as well as data processing costs, can be a limitation. Therefore, it is proposed the Fog Computing architecture, which is used as a mediator among IoT devices that generate and demand data (e.g., cellphones, video cameras, sensors) and Cloud infrastructure. The purpose of Fog Computing is to relieve the Cloud server load and to delegate it to intermediate devices. In this context, it is essential to measure the performance to evaluate the solution and exploit all the advantages provided by Fog nodes. This paper presents a performance efficiency quality model for Fog Computing applications. The model breaks down in sub-characteristics and attributes with defined metrics and thresholds that should be used to evaluate these kinds of applications to understand how efficient is the use of computational resources (i.e., time, processing, memory). Also, it is offered an evaluation method that is supported by the quality model to assess the software development process for Fog Computing applications. The evaluation method is aligned with the ISO/IEC 25040 standard and indicates the developer steps towards a good quality Fog Computing solution.
