The objective of this study is twofold: First, it aims at analyzing and interpreting Brazilian products exportation from 1997 to 2019. Second, it seeks to reduce the scope to the Alagoas state – one of the nation’s poorest states – to identify possible exportation growth opportunities. Thereby, the study was conducted by using the model Product Space, which can show us, through a network, if it is possible to industries produce new products from those already produced by them. After analyzing the Product Space, we concluded that Alagoas is not isolated in the network. Alagoas can grow its network by exporting more than 50 products, such as motor vehicles, chemical wood pulp, and passenger cars. Such growth can promote new public and private partnerships. Thus, new industries might be attracted and boost Alagoas economic growth.

Resumen Espectáculo
-
Vehicle networks have great capacity for the production and dissemination of content, however, the constant topological changes make it difficult to exchange information be- tween nodes and can invalidate the information, generating information losses, packet delays, improper disconnections, among other problems. In vehicular networks there are places where the content generated by the sensor nodes reaches a larger audience, these places which we call Anchorage Zones are used for exchanging relevant information with greater connectivity. The information disseminated in an anchor zone is known as Float- ing Content because it has local, temporal and spatial validity. We developed a study using metrics of complex networks such as, Betweenness and Degree together with flow measures, applied to data from real bases and simulation with the proposal to determine the best zones for exchanging information in a vehicular network. The results show that the methodology used is effective for characterizing anchor zones in vehicular networks, because the information extracted with the discretized time is better approximated to re- ality, eliminating edges that no longer exist between the nodes of the network, differently from the aggregate time that stores information for edges that no longer exist.

Resumen Espectáculo

This work presents an interdisciplinary assessment that looks in-depth the tracking of air quality in urban environments. This kind of application is well suited to be approached with the paradigm of wireless sensor networks in their overall variations. Therefore a robust and diverse set of solutions have been developed following the technology capabilities advance. The proposed experiment takes advantage of Vehicle Sensor Networks (VSN) by embedding sensor nodes to public transportation, addressing this study case with bus lines within such a way that the mobiles spread the sampling activity through a large number of different places visited during the route. Simultaneously, it alleviates restrictions of power management, packaging dimensions (size and weight), and overall maintenance issues. We perform environmental modeling based on real data considering a temporal and spatial multivariate behavior on observed phenomena. We define the city of São Paulo as reference for the case study and parsed the asserted data to create a multivariate map of samples, showing the behavior of five different air pollutants (CO, O3, PM10, NO2 and SO2) simultaneously while it also varies in time. The current development stage covers a set of handling processes over an input data that has unformatted or missing information due to being sourced from real sensors and the creation of the map mentioned above. Our methodology addresses 1) the mentioned environmental simulation, 2) deploying mobile sensor nodes and perform sensing process, 3) implement network activity and delivery of collected data, 4) predict a view of a monitored environment based on gathered data with the same strategy previously applied to create the initial field. Finally, we plan to evaluate system-level performance and operational constraints through an event-based simulation, taking into account a detailed description of roads, bus lines, vehicle itineraries, and overall traffic information.

Background: Obesity is a major public health concern worldwide. Studies suggest that gut microbiota has several functions related to host health. Administration of probiotic may affect the gut microbiota. This systematic review aims to evaluate the effects of oral supplementation with probiotics on the intestinal microbiota in obese people.
Methods: Our systematic review aimed to evaluate the results of Randomized Clinical Trials (RCTs) on intestinal microbial changes in obese people after the administration of probiotic supplements. We searched five literature databases (EMBASE, MEDLINE, ISI - Web of Science, Scopus and CENTRAL). The protocol this study was registered in PROSPERO (International prospective Register of Systematic Reviews).
Results: 2.425 records were identified during the literature search. After the review of the titles and abstracts, 29 publications were selected for a review of the full texts, of which only 9 met the selection criteria and three were includede to meta-analisys. 2 studies showed no significant difference in the bacterial phylum. 6 studies showed only significant changes in some genus. The comparison of studies shows the existence of changes in the intestinal microbiota of obese people after the use of probiotics.
Conclusions: The findings suggest that oral supplementation with probiotics may offer beneficial changes on gut microbiota. Based on the evidence in this review, some specific strains of probiotics alter the intestinal microbiota in obese individuals. However, some studies have reported that there have been no significant changes on gut microbiota diversity in obese people. It suggests that further studies are needed to determine the size effect of probiotic therapy.

This work proposes the implementation of a variation of Holland's genetic algorithm, to follow the evolution of a patient's posture through the analysis of exams performed by the patient himself with the help of a mobile device. The purpose of this system is to assist the patient in identifying the presence of changes in the spine called kyphosis and lordosis, at which time the patient will need to seek medical help. Therefore, the system should receive information about the limits of the spine angles considered normal, acceptable and critical for kyphosis and lordosis. Then, the system will request monthly self-diagnosis, generated from a profile photo of the patient taken by a mobile device, from which a set of information is extracted, which are recorded in a database, for analyzed by a genetic algorithm. The genetic algorithm generates several possibilities of evolution for the patient's column based on the information recorded in the database, if this information leads the genetic algorithm to find a situation considered critical for the patient in the coming months, the system will display a message on the screen cell phone informing the patient of the need to see a doctor to evaluate his spine. To validate the implementation of the referred system, simulations with images generated with photoshop were made. The results obtained with these simulations demonstrate the system's ability to anticipate changes in the patient's posture in advance that can lead to kyphosis or lordosis.

The incidence of diabetes mellitus has risen sharply and its prevalence poses a major threat to global health. The human gut microbiota refers to microbes that colonize the gut and participate in various functions that benefit the host. Studies suggest that probiotics can be administered in alterations of the diabetic microbiome to restore the composition of the intestinal microflora. This systematic review aims to assess the effectiveness of ad- ministering probiotics in people with type 2 diabetes mellitus. Methods: Systematic review was conducted with the aim of evaluating the results of Randomized Clinical Trials (RCTs) on intestinal microbial changes in people with type 2 diabetes mellitus after administration of probiotics. Five literature databases were considered (EMBASE, MEDLINE, ISI - Web of Science, Scopus and CENTRAL). The protocol that delimits this work was registered in PROS- PERO (International Prospective Register of Systematic Reviews). Results: 973 records were identified during the literature search. After reviewing the titles and abstracts, 58 publications were selected for the complete reading of the texts, of which only 4 met the selection criteria and were included for meta-analysis. The methodological quality analysis classified 2 studies as "high risk of bias", 1 as "some concerns" and 1 as "low risk of bias". The 4 studies showed changes in some genera of bacteria after intervention with probiotics. Conclusions: The results obtained from this systematic review and meta-analysis suggest that the effect of probiotic supplements on the intestinal microbiota of diabetic patients has been inconclusive and that a larger quantity of Randomized Clinical Trials is needed to expand the number of participants, with a longer time interval and to provide detailed information on the diversity of the gut microbiota to fully assess the size of the effect of this therapy in the treatment of type 2 diabetes mellitus.

Context: Endurance exercise is defined as that performed for a long period and at moderate intensities, and can be performed in different modalities. Studies suggest that the intestinal microbiota has several functions related to the health of the host. The practice of Endurance exercises can alter the intestinal microbiota. This systematic review aims to verify the effects of endurance exercises on the intestinal microbiota. Methods: A systematic review was conducted with the aim of evaluating the results of Randomized Clinical Trials (RCTs) and Non-Randomized Clinical Trials (NECR's) on intestinal microbial alterations in endurance exercise practitioners. Five literature databases were considered (EMBASE, MEDLINE, ISI - Web of Science, Scopus and CENTRAL). The protocol that delimits this work was registered in PROSPERO (International Prospective Register of Systematic Reviews). Results: 1965 records were identified during the bibliographic search. After reviewing the titles and abstracts, 27 publications were selected for the complete reading of the texts, of which only four met the selection criteria. No study failed to demonstrate a significant difference in the bacterial phylum, with some caveats. Four studies showed only significant changes in only a few genders. The comparison of studies demonstrates the existence of alterations in the intestinal microbiota of people who practice endurance exercises. Conclusions: The results of this review suggest that endurance exercise has the potential to offer beneficial changes in the gut microbiota. Based on the evidence from this review, some samples of the selected works had alterations in the intestinal microbiota. However, some studies reported that there were no
significant changes in the diversity of the gut microbiota of individuals engaged in endurance exercise. This situation suggests that further studies are needed to determine the size of the effect of endurance exercise.

Resumen Espectáculo

The search for increasingly efficient learning in online environments has encouraged the growing development of research. Learning is often perceived as a tedious activity, which intensifies the very high dropout rates. In recent years, several methods have been applied in order to keep the student engaged in the learning environment in such a way as to transform the tedious activity into a pleasurable and fun one. Computer games allow students to experience ways of learning that demonstrate immersion in a practice, supported by structures that lead to professional experiences and skills, thus, games are seen as a tool that facilitates and supports student learning. In this sense, Gamification uses game elements in non-game environments, with the aim of promoting student engagement, transforming the tedious activity into a pleasurable one. Although several works show positive results with the use of gamification, it is common not to get the student to awaken independence in the learning process. Self-regulation of learning is characterized as the student's ability to act in their learning environment, reflecting and making decisions about which path would be more convenient for better learning. In this way, the student acts in an active and constructive way in the process, in which they establish goals that will guide their learning. In this sense, the OLM (Open Learning Model) enables the opening of the student model, and thus, the student will be able to view information related to the learning process itself, allowing active participation in the learning process, being able to make decisions about which are the paths that generate more results for him in the online environment. Thus, the present work aimed to verify, through a controlled experiment, whether the use of gamification in an online environment with an open model would bring significant results in self-regulation and student learning. For this, two open model environments were compared, one with and the other without gamification, in which students (schools, institutes and public universities) would have to answer 15 questions in an application developed for android, the first 10 being common to all and the other 5 questions customized by them, regarding the level and content of the questions, and at this stage the student would have the version with or without gamification, randomly distributed after accessing the application. The results showed that there was no significant difference between versions with and without gamification, both with regard to self-regulation and learning.

Cataract is the leading cause of blindness in the world, despite being reversible with simple surgical treatment. In recent years, efforts have been made so that cataract surgery, in addition to treating blindness, would also correct pre-existing refractive defects through the choice of intraocular lenses with adequate convergence power. The choice of the power of the new lens is made through biometric formulas that have been developed over the last 50 years. Despite showing good results, there is room for improvement, especially in patients with atypical eyes. In this study, multiple computational models were developed in order to assist the ophthalmologist in preoperative decision-making, through predictive algorithms that assess whether the patient will likely obtain a good result with a given lens and biometric formula.

With the development of high violence games, such as: Mortal Combat, Carmageddon, Doom, GTA (Grand Theft Auto), these games are banned in Brazil and in several countries around the world due to their high violence, games in this category pass on the teaching of that to be successful in the game it is necessary to practice unethical attitudes such as: lack of respect, injustices, theft, lack of solidarity, illegal attitudes; emerges as an alternative the Solidary Educational Digital Games (JDES) which aim to place the player in environmental scenarios, catastrophes, having a chance to perform ethical or unethical attitudes being rewarded or punished according to their attitudes. For the development of solidary educational digital games, it is essential not to always start the creation from scratch, beginning, it is essential to use software reuse techniques. This work presents a Conceptual Framework whose purpose is to streamline and cheapen the development of JDES. The Conceptual Framework was divided into two stages, the first was developed through UML modeling (Unified Modeling Language) the Framework Digital Games Educational Solidarity (FJDES) and Auxiliary Classes that were used to create the Solidary Educational Digital Game Flood, in the second step was developed through Agile Modeling and Scrum Method the Scrum Framework Educational Solidarity Digital Games (FSJDES), where the Framework Educational Solidarity Digital Games and Auxiliary Classes already developed in the first step was reused for the creation of the Digital Educational Solidarity Game Earthquake, both games were implemented in Java. As a result, there was a three-month reduction in the development of Solidary Educational Digital Games, where the production of the first game took four months and the second game took a month.

The present work has as main objective to analyze what determines the student's confidence in the recommendations of online courses. The analysis will feature a systematic literature review to identify the articles that best define the relationship between trust and acceptance of pedagogical recommendations. The review will define the impact that recommendations have on user confidence, whether automatic, manual or the consistency of what was recommended. In addition, we will carry out an experiment with simulated data to measure students' perception of confidence in the recommendations suggested in the online environment in order to identify whether students prefer recommendations from a teacher or a machine, also measuring the transparency of the process choice as to whether or not to know who the recommendation comes from. We hope to contribute to the understanding of the dynamics of student confidence in online environments, as well as provide theoretical and empirical foundations for the improvement of pedagogical recommendations in distance learning environments.

Online learning environments were developed as an online way for students to interact with their teachers, colleagues and course content. These environments have pedagogical resources in quantity and diversity, allowing recommendations from these to students, based on their respective needs, in addition to the skills that should be developed. However, there are limitations in these recommendation systems in online learning environments, especially in relation to the quality of the recommendations, leading to problems regarding the acceptance of the recommendations by the students. One of the factors that can lead to non-acceptance of the recommendations received is the lack of confidence. A possible approach to this problem is to explain to students how this recommendation was created. For this, we intend to identify if there is a difference in relation to the students' confidence in the recommendations: (1) when the recommendation has an explanation coherent with the problem faced by the student; (2) When the recommendation has an explanation not consistent with the problem faced by the student and; (3) When the recommendation is not explained. To evaluate our proposal, we will use simulated data from student interactions in an online course to generate recommendations based on the interactions and needs of the students (simulated). Then, we will create the explanations for the recommendations created and evaluate, using a questionnaire, the effect of the explanation's coherence on the students' confidence in relation to the pedagogical recommendations. We hope with this proposal to contribute to an improvement in the quality of the recommendations and to increase students' confidence in relation to the pedagogical recommendations in online learning environments.

The use of Information and Communication Technologies is increasingly evident in educational environments. Online educational platforms can help students and teachers in the formative complexity of teaching and learning in different areas of knowledge. Among the e-learning platforms, the Intelligent Tutoring Systems - ITS allow an adaptive educational environment supported by automated resources of recommendations, carried out by artificial intelligence techniques, aiming at students' learning according to their user profiles. ITS revolutionizes how this information interacts with students and teachers by taking traditional teaching from the classroom to personalized online educational environments. Many researchers develop gamification techniques to increase motivation and avoid the adverse effects (boredom) of using these ITS. However, many issues may be considered to understand the effectiveness of teaching/learning in gamified STI environments; one of them is the active participation of the teacher in the authoring of the knowledge domain to be worked on in the gamified STI, as well as in the pedagogical monitoring students, in a simplified way. In this sense, researchers have become increasingly interested in providing teachers with strategies to monitor and adapt gamification design in the context of STIs to utilize teachers' inherently human capabilities to adjust gamification design according to student performance. This study will compare the results of using recommendations through missions in a simulated scenario of a gamified environment, automated by the STI, with and without the teacher's intervention, analyzing the data generated by the platform and suggesting missions according to the observations of the monitoring data. For comparison purposes, this dissertation will propose the evaluation of three simulated environments, where teachers will analyze one of three monitoring scenarios of an educational platform (manual, automated, and semi-automated). Each of the scenarios will be used in a randomized experiment, where participating teachers will assess through a form what is their perception of cognitive effort and time dedicated to creating recommendations for missions and monitoring students on the platform.

Early identification contributes to language development and other developmental milestones in children with hearing loss. After diagnosis, parents end up having to make several decisions regarding the treatment of their children. In the Brazilian literature, no instrument was found available to provide support for parents' decision process. To address this gap, this work aims to translate and culturally adapt a monitoring screening protocol for parents and professionals that targets children with hearing loss. For this, two studies were conducted. The first consisted of a systematic review of the literature and meta-analysis on the influence of the intervention on the oral language development of children with hearing loss. Fifteen studies were part of the qualitative synthesis and twelve of the quantitative synthesis. According to the summarized data, the age of identification and early intervention allowed children to achieve near-normal speech and language outcomes, both of which can be obtained by growth curves using standardized language scores. The second study consisted of the cultural adaptation and adaptation of 452 items of the Success from the Star protocol, corresponding to all principal areas of language development: communication, listening, listening, and vocalization. Judges evaluated 25% of the items on the following categories: 1) cultural suitability, 2) conceptual clarity, and 3) suitability to the target audience. We proposed a back-translation to consolidate the final items. Subsequently, the translated items were compared with the revised version of the instrument, which comprises 347 items in the two areas of development. A committee of experts qualitatively evaluated the instrument to validate its content. In addition to committee valuation, we conclude with some directions to effectiveness validation through its use by parents and professionals.
