This paper presents a research proposal which has been developed as a doctoral thesis in the PhD program in Computer Systems Engineering at the Universidad del Norte since August 2015. This research focuses on the analysis of cell images of the human bronchial epithelium infected with the Respiratory Syncytial Virus in order to understand the mechanisms of entry of the virus into the human body. Due...
This work presents an analysis of some terms related to Big Data, Hadoop, and their architecture; in addition, it presents the results of the analysis of undergraduate enrollment information of the distance system of Universidad Tecnica Particular de Loja (UTPL), this information is extracted from academic system by using Hadoop framework as a big data processing platform; for that, a big data infrastructure...
The higher education through virtual environment is students centered oriented to the interactive learning, in situations to be closer to the real world; for that reason, teachers must have new communicative competences, nonverbal and with a learning innovative approach which allows to guide their students in the complex process of acquiring knowledge even more in a foreign language. In the same context,...
The impact of efficient Information System Strategy Plans has proven crucial to modern-day corporations. However, during the analysis phase for a technical solution to fulfil an identified need in an enterprise, many teams tend to focus on a very issue-specific analysis and overlook its underlying global corporate impacts. On the other hand, it is difficult and time-expensive for these teams to analyse...
Software evolution is a well-established research topic, but not in the web applications area. Web projects are normally more complex than other software development projects because they have both server and client code, encompass a variety of programming languages, and are multidisciplinary. We aim to produce a catalog of web smells to help mitigating quality problems in web apps implementation,...
Background: Code smells have long been catalogued with corresponding mitigating solutions called refactoring operations. However, while the latter are supported in several IDEs, code smells detection scaffolding still has many limitations. Another aspect deserving attention is code smells visualization, to increase software quality awareness, namely in large projects, where maintainability is often...
The multidisciplinary nature of information visualization is today fairly consensual in both professional and academic communities: data analysis, information design, storytelling, among other subjects, are common drivers in this field. The systematic study of this cross-fertilization, patent in the way the concept's definition varies according to the perspective being adopted, represents an important...
Older adults can suffer from neogogenerative diseases, which makes them dependent on trained personnel in geriatric centers. The main contribution of this paper is a conceptual model that seeks to delineate the implications for the design of a data visualization tool for older adults's care centers. The proposed model is created through grounded theory. The results obtained in the qualitative analysis...
Understanding the learning strategies conceived by self-directed learners has become a major challenge to be found in contexts supported by sub-domains of learning. For this objective to be achieved it is necessary to understand the different approaches that dimension the phenomenon, to explore the technologies created for this purpose and to discuss the results and limitations obtained through the...
This document proposes to make a contribution to the conceptualization and implementation of data recovery techniques through the abstraction of recovery methodologies and aspects that influence the process, relating human motivation to research needs, whether these are for the Auditing or computer science, allowing to generate classification of recovery techniques in the absence of the metadata provided...
The following article outlines the online activity and social presence of chosen world leading fast food restaurants: McDonald's, KFC, Burger King and Pizza Hut. The analysis was done to examine how these companies use social media as a mean of engaging with their customers and how successful they are in doing so. The results show social media create meaningful insights and benchmarks for businesses...
The increasing human longevity around the world calls for new attention models in which the primary caregiver plays a crucial role as a source of care supply. However, primary caregivers' lack of training, along with high levels of stress, depression and anxiety, can have a negative impact on both the caregiver's health and the development of caregiving duties. Hence, the objective of the present...
Adaptability in ubiquitous learning environments has been widely discussed in the literature and a challenging point is focused on the perception of users' profile and what strategies can be offered to keep them motivated to learn. Thus, it is necessary to identify interaction strategies based on the principles of ubiquitous learning (u-learning), especially those associated with learning situations...
This work is about an ongoing research that has the objective of developing a service that captures the informal learning activities from the PLE so it can aid the formative assessment process in formal collaborative environments, such as the LMS. This investigation counted on the participation of 49 apprentices of distance-learning courses from different institutions in Brazil. Through the results,...
The innovation applied to business management has become a key element in the valuation of organizations in the global society environment, as well as their own survival in the markets in which they interact and in which it plays an essential role in the relationship of those with their audiences, while transcending the classic approach to the product to cover other areas such as procedures, communication,...
Nowadays an important issue, for an organization is to be able to implement relevant anti-bribery risk management systems with mandatory laws. Managers strive to reach an equilibrium between a pure mandatory rule oriented organization and people freedom of choice to mitigate bribery on organization. The problem is how to develop and manage efficiently anti-bribery system in an organization without...
The big amount of data generated nowadays are being used by Big Data tools to generate knowledge and to facilitate the decision-making. However, this situation creates a new challenge: how to visualize all these data without losing mid/long term crucial information. The purpose of this article is to analyze the state of the art on massive data visualization, main problems and challenges of information...
Social networking websites are increasingly used as tools to communicate between people, whether these consumers or companies. Facebook is one of the most users platforms in the world and is also highly valued as a communication tool by companies. In this field, the present research establishes several factors of interest to contemplate in the creation of a communication strategy in Facebook, focusing...
The actual development of the IT sector generated software products that are now a significant part of any field. The increasing number of IT products led to changes in the project management of software development. If, in the beginnings, the project management tools were limited and included approaches such as: the waterfall model, the incremental spiral model, prototyping, and rapid application...
The objective of this study was to verify if a development model of Units of Learning (UoLs), supported by UoLs authoring tools, that meet the usability criteria and abstract advanced knowledge in programming language by the developers, effectively provides the use and implementation of such resources by teachers in all areas of high school (in this first phase of the research) with few skills with...
