This article presents a simple guide that supports the pedagogical planning process. Besides the knowledge that will be shared, structuring an learning unit or a course demands reflection and effort in the teaching/learning development. The work described in this paper proposes a guide that speeds the process of defining online learning strategies by crossing cognitive objectives, pedagogical models, techniques and free web tools. The usefulness of the results obtained can be viewed on the perspectives of both student and teacher, thus it is a mediation instrument among all the players in the learning process. At the same time, it helps the bureaucratic procedures that are usually associated. We conclude this paper by presenting a set of recommendations obtained by the application of the pedagogic planning suggested in an implementation of an online course.

Excessive electric energy consumption results in high costs for consumers, and often on using non-renewable resources. Additionally, in many cases, it is difficult for the consumer or for the energy provider to determine if one or more equipment is being used efficiently. Therefore, the main objective of this work is to promote awareness about energy consumption. For that purpose, a mobile application with a gamification approach was designed to identify users' behaviors towards the use of energy and, based on the user's answers, offer advices to save energy and promote ecological awareness. The outcome of using gamification on a mobile application with such goals results in a streamlined data collection application that combines information and entertainment. The collected information is being gathered to potentially create consumer profiles that better reflect the user's energy consumption.

The hospital area is constantly in need of care and attention. Because of its urgencies, it has vulnerabilities and risks that hinder the quality of hospital management. Technological management tools are effective in improving processes and strategic administration because they provide information reliability. The aim of this work is to propose to the Brazilian Federal University Hospitals (FUH's) the use of an open source Business Intelligence (BI) tool, Pentaho, to analyze the Hospital Occupancy Rate (HOR) and support clinical decision making. This paper describes BI and Pentaho, as well as the main points of the E-EFI-01 efficiency documentation established by the National Agency of Supplementary Health (NASH), with emphasis on the hospital indicator Occupancy Rate. Through Pentaho, is made the data extraction and the transformation, as well as loading them into the Data Warehouse (DW), all based on a relational database of the Brazilian Hospital Services Company (BHSC). After that, dimensional cubes are created for the generation of graphic panels in dashboards. It can be seen that most BHSC hospitals are not yet adequately using their operational beds, being outside the goal established by NASH. Several steps are taken to achieve efficient hospital administration, but the joint working of Information and Communication Technology (ICT) solutions with the health area and its standards, provides a major step towards efficient hospital management.

In the last years, the appearance of new and revolutionary technologies has changed the society in all its aspects (economy, feeding, personal relationships…). Education is not foreign to these changes. Genuine concepts such as collaborative learning, massive courses (MOOC) or flipped classrooms have been incorporated at every educational level, although the maturity of students allows a greater capacity for innovation at higher education. Together with these concepts, new technological tools have been employed with educational purposes. In particular, wikis have been reported as ideally suited for collaborative learning. Thus, nowadays, several Universities around the world are running projects and events about the use of wikis in higher education. Therefore, in this paper we explore the use of wikis in the higher educational institutions, being focused on a special case: Wikipedia. Wikipedia presents special characteristics which make it perfect to reach not only the specific learning objectives of a certain particular subject, but also the transversal abilities so demanded today (such as teamwork or social responsibility). The research methodology followed is based on a review and update of the collaboration between the University and the Wikipedia. In particular, we analyze the collaboration of the Spanish and Hispanic American Universities in its different manifestations. In this work, we explain the most interesting results about this collaboration. We observe one increasingly activity over this collaboration due to the greater number of universities that are incorporated, especially in the last five years. Finally, we analyze more deeply the experiences about the use of Wikipedia conducted in the Technical University of Madrid and we present the obtained results.

The problems commonly associated with virtual education and the academic objectives that support higher education have not been unified in the specialized literature yet. How to achieve this unification? Through motivational strategies which achieve the success of virtual courses. These strategies must be totally different from those applied in face-to-face courses, since motivational factors in virtual education and face-to-face education are evidently different. Therefore, in this paper we propose two strategies to be used in motivating the undergraduate students, in order to improve performance in the subject of Programming Fundamentals in virtual mode. It is proved that fail rates of students decreased in groups were the motivational strategies were applied.

Organizations felt the need to quickly process information in an efficient way in order to support decision-making, thus leading to the emergence of Business Intelligence systems. Their use in organizations has become crucial in the treatment of large data volumes, and providing relevant information, in order to assertively support decision-making. This article presents the design of a data mart for the financial resources of a public organism with the objective of responding to the data visualization and processing needs of the respective organism. Posteriorly a prototype was developed with the objective of evaluating, through the TAM model, the usability, utility and easiness of use. The sample chosen to evaluate this data mart and the respective data processing was made up of university students who attended the curricular unit of Business Intelligence II and who had the knowledge to do this evaluation.

Electrical Grid we have is more than 50 years old. The integration of information technology to the electric grid system is expected to address many shortcomings of the current and traditional electrical grids that have resulted in Smart Grid which is gaining lot of interest and momentum. In Smart Grid, Power Distribution is one part which requires monitoring and control. Lot of technologies and have been applied in Smart grid towards sensing and action. Supervisory Control and Data Acquisition (SCADA) system is very well proven within the substation region. There has been very less monitoring done on the distribution side due to the geographical distribution. Currently, Internet of Things has paved way for connecting huge number of devices to the Internet which would be very much effective and beneficial for power distribution and Automation. So accordingly, an IoT based SCADA integrated with Fog for Distribution Automation system has been proposed which takes care of the consumer utilization, outage management, power quality control and pole transformer health. This is supported by fog computing which does real-time streaming analytics. This helps in reducing the internet bandwidth and latency for immediate control action.

Education professionals are always searching for new ways of promoting learning, either by modifying the pedagogical project of courses or by the adoption of new learning strategies. In particular, this paper presents the results of an effort in order to bridge the knowledge acquired by students within classroom in face-to-face classes with technical skills required in real life situations. The contribution presented in this paper is the result of an assignment applied within an undergraduate Data Network Infrastructure Design course in a Brazilian university using an adapted Problem-Based Learning methodology (PBL), as a motivational tool. This paper also presents and discusses the resulting data related to the learning assessment.

Open access scientific journals allow scientific information to be published on the Web. Open access is immediate access, without registration, subscription or payment requirements to online digital material free of most of the restrictions imposed by traditional copyright. When talking about open access, it is often indicated that it is "barrier-free" access. However, the access barriers faced by people with disabilities often persist. Open access is access free of technical, legal or financial restrictions. Websites that provide open access must meet web accessibility standards in order to minimize the barriers that impede access to information for people with disabilities. However, web developers often do not have the knowledge to meet web accessibility standards. Several evaluation tools have been developed to verify that a website complies with web accessibility standards. In this article we present the results of an analysis of the web accessibility of 101 websites of scientific journals with open access in Latin America. EXaminator has been used as an automatic evaluation tool to detect the most important problems of web accessibility. The results show that most of the top page of the websites analyzed do not meet web accessibility standards. Finally, based on the results obtained, some recommendations are offered to help improve the accessibility of this type of websites.

This research work is aimed at the estimated two regression models, with which it is intended to measure the fragility of Ecuadorian companies. Development and scope of the proposed objective, the information in the financial statements of 34.575 both large companies are used, medium, small and micro enterprises that are controlled and monitored by the Superintendency of Companies in 2013, plus a selection of be held companies for the development of this work because the account information is limited for some companies in the total sample used in this study is of 22,854 companies. The methodology used in this work is to estimate two models of discrete selection: Logit and Probit. With the information available balance sheet financial indicators were useful as explanatory variables in the models posed regression, from which relevant financial ratios such as ROA, ROE and liquidity are identified were built, use is also made of financial gaps of patrimonio-debt and cash for measuring the fragility of companies. The results show a negative influence Slacks used, as in this case increase the fragility of Ecuadorian companies into bankruptcy, a positive value of ROA equally evidence the probability of default on payment obligations as they thus it reduces profitability increases the fragility of a company into bankruptcy, while a positive value of ROE reduces the brittleness of the company.
