    Mobile instant messaging (MIM) is one of the most influential technologies in society today due to its wide penetration in the world’s population. The present study aims to establish whether two consumer traits, extraversion and novelty seeking, have the potential to explain the intensity of MIM usage by consumers considering its good performance in explaining other consumer behaviors. The present study is based on a survey of 682 adults in Quito, the capital of Ecuador, which is a South American developing country. The data obtained are analyzed with structural equation modeling and establish that while extraversion is not related to the intensity of MIM use, novelty seeking does have a direct and positive effect. This study makes recommendations for business theory and practice. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

    The doctrine of the lifting of the corporate veil was created precisely to prevent abuses in the use of legal status, and consti-tutes a way that allows creditors to penetrate the patrimony of the partner or shareholder. The objective of this research is: To establish a reflective, critical and legal analysis of the legislation applicable to the lifting of the corporate veil for the execution of work-related sentences in Ecuador. The methodology that was applied was Historical-Legal-descriptive, because it allowed the historical monitoring of the subject of study and through the application of the analytical method. An important fin-ding of this work has been the analysis of cases, where the rights of workers, despite being recognized under a court ruling, cannot be fully enforced, due to having preceded fraudulent maneuvers by members of the legal entity that have simulated legal acts, to hide the assets of the companies and leave the workers unprotected. As a conclusion of the breaking of the hermeticism of the legal entity, it seeks to protect the rights of creditors, with the application of procedural actions regulated by law, and to link unpaid obligations to the assets of natural persons behind the corporate facade. © 2021, University of Cienfuegos, Carlos Rafael Rodriguez.

    The research develops an industrial software application called FAPS System for the planning and scheduling manufacturing. It contains three modules used for planning and programming of resources, process management and Andon module focused on the use of lean manufacturing techniques for the notification, emission and display of contingencies presented during the production in real time. A case study is described in Ecuadorian footwear companies for the execution of experimental prototype efficiency tests. Through the unified modeling language diagrams, the requirements and functionalities of the software developed based on private and free technologies are defined. The planning module has a scheduling algorithm of days based on weighted standards that allows to estimate the delivery date of a production order, reprogram it and compare the planned quantity with respect to the capacity used. The Andon module is an Android application that consumes the information managed in the planning and process modules, thereby monitoring in real time the state of the plant and the production progress. The experimental results show that the system is adaptable to multiproduct orders and the scheduling allows to increase 6% the utilization percentage of the production processes.

    For several years now, several computational processes have been investigated in conjunction with the new techniques of artificial intelligence, data mining and the use of algorithms that are in line with the classification of data that they have contributed in other contexts such as The case in the areas of medicine especially in neurological diseases such as Alzheimer's, Parkinson's and Huntington's for this case was the study of Alzheimer's disease that affects the elderly in their cognitive and behavioral functions, the objective of this research is oriented to manipulate existing data of the disease supported by the use of the negative selection algorithm that is part of a classification of the context of genetic algorithms, classification techniques use decision trees, Naive Bayes, System Networks Neuronal Supervised Classifier and, the decision trees represent the decisions of the In the data, naive bayes is exclusive of a probabilistic context, the neural network that is based on an environment of the biological model, UCS is identified in a type of rules of a condition and action. The results have been from the origin of data from a patient population of 499 original instances and 1001 generated by means of the negative selection algorithm, the detection rate and the false alarm rate after the mathematical process justifies the validity of the data evidencing the way in which the data have been properly manipulated and verified, finally it is concluded that this type of algorithms is the case of negative selection and also in applications with conditions similar to neurological contexts as in the case of this investigation. It can also be stated that the classification techniques and their applicability make it possible to determine the use of metaclassifiers that are subject to the identification and verification of the results of the research carried out. © 2018 AISTI.

    This work presents the kinematic and dynamic modeling of a humanwheelchair system where it is considered that its mass center is not located at the wheels’ axis center of the wheelchair. Furthermore, it is presents a new motion controller for human-wheelchair system that is capable of performing positioning and path-following tasks. The proposed controller has the advantage of simultaneously performing the approximation of the robot to the proposed path by the shortest route and limiting its velocity. This controller design is based on two cascaded subsystems: a kinematic controller with command saturation, and a dynamic controller that compensates the dynamics of the robot. © Springer International Publishing Switzerland 2015.

    This qualitative work aimed to understand the social construction of violence in adolescents victims of trafficking for criminal purposes. Four life histories were made, which were analyzed through the dialectical hermeneutic method. The results show three main categories related to social history, family history and personal history. Adolescents have been participants in a violent social and family context, child labor, family violence, socioeconomic precariousness and gender violence, so that the social construction of violence is a determining factor in vulnerability to trafficking. © 2017, Universidad del Zulia.

    Q’inqu: Inclusive Board Game for the Integration of People with Disabilities
    The educational inclusion of people with disabilities continues to be a great challenge for society. Due to the field’s diversity and complexity, people with disabilities have few opportunities to be integrated into educational activities or even entertainment. This article describes a novel educational resource developed within the field of applied technologies. Q’inqu is an inclusive board game that encourages the family and educational inclusion of people with disabilities. Q’inqu is a Quechua word meaning “Labyrinth”. This is a metaphor for the challenges faced by families living with a person with disabilities, and it also reflects its narrative structure based on the “Legend of the Incas’ treasure”. Q’inqu has the general theme of a traditional board game where turns are taken until the treasure is found. What makes it different is the integration of inclusive elements through the use of technology. There are cards with a braille code, a rectangular board with high relief, and a circular board with textures. An App reads QR codes and also patterns, which present additional information based on augmented reality. These features provide support to blind players and to those who are unable to read, making the game both entertaining and educational. Q’inqu was developed and tested by a multidisciplinary team of 80 people, which included students and professionals from design, education and pedagogy. The most relevant result was that out of 367 ideas that were presented, it was awarded first prize in the category Toys for children with disabilities in the CMA contest held in Ecuador. © 2020, Springer Nature Switzerland AG.

    The educational disorders that children present at an early age can cause them to not fully develop throughout their lives. In this research work a 3D virtual system that allows the child who has been diagnosed with dyslexia to complement the exercises performed in a conventional therapy is described. To achieve this an application was developed, the app consists of two games (each with three levels of difficulty), and that are part of the rehabilitation program. In each of these games virtual objects are combined with auditory messages to provide the user with an immersive experience, and to train more than one sense at a time. In the first game task, the activity asks the children to correctly locate the syllables that compose a word and for the second activity the children will listen to a word, after the games asks the children to select the correct word. This tool has been tested by a group of children (eight), with ages ranging from 8 to 12 years old, whose development can be supervised at home by their parents, since it is an intuitive and easy to use interface. The results obtained are stored in a database and in this way the medical specialist can monitor the progress of the child throughout his treatment. For the validation of this proposal the SUS usability test was used. © Springer Nature Switzerland AG 2020.

    In the last decade, education in Ecuador has improved due to the effectiveness of public policies. University legislation has implemented profound changes in the search for quality at all levels, which represents a challenge for the training of teachers. In this sense, the objectives of this study were to identify the research skills that are most difficult to acquire for students in master's education programs in Ecuador, and to explain the role of critical reading in their development. An exploratory study was carried out, using comparative analysis to examine the qualitative data derived from the monographs written by these students; evaluating your performance in presenting such results; likewise, two discussion groups were formed with the same students. The results of this first phase revealed weaknesses in research capacity, which are attributed to deficiencies in a sufficient critical reading to achieve the expected objectives. It is concluded that the use of critical reading is an indispensable precedent for the achievement of complex competences such as research, therefore, it requires an interdisciplinary, methodological, systematic and unified work in the teaching of all the modules that the program covers. © 2020.

    Classifiers are tools widely used nowadays to process data and obtain prediction models that are trained through supervised learning techniques; there is a wide variety of sensors that acquire the data to be processed, such as the voltammetric electronic tongue, as a device employed to analyze food compounds. This paper presents a normal and decaffeinated coffee beverage classifier using a Support Vector Machine with a linear separation function, detailing the classification function and the model optimization method; to train the model, the data measured by 4 electrodes of a voltammetric tongue that is excited by a predetermined sequence of positive pulses is used. In addition, the results graphically show the measurements obtained, the support vectors and the evaluation data, the values of the classifier parameters are also presented. Finally, the conclusions establish an acceptable error in the classification of coffee drinks according to caffeine presence at the sample analyzed. © Springer Nature Switzerland AG 2020.
