Furthermore, resilience can be described as the ability which allows an individual or group to hold up well before unfavorable situations. This study aimed to identify nursing workers’ resilience at a psychiatric hospital in Brazil. This is an exploratory research with quantitative data approach. The sample consisted of 56 workers, using the Resilience Scale. Of the 56 subjects, 45 (80.4%) were women; 22 (39.2%) were 20- to 40-years-old and 30 (53.6%) were 41- to 60-years-old; 11 (19.6%) were nurses and 45 (80.4%) were technicians or nursing assistants. The results also showed that 50% of subjects showed a high resilience degree and 42.9% an average resilience degree. Thus, it was found that workers seek to develop protective factors in coping with a work environment that does not value the individual subjectivity and does not allow professional development, discouraging workers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20promotion" title="health promotion">health promotion</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing" title=" nursing"> nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20health" title=" occupational health"> occupational health</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a> </p> <a href="https://publications.waset.org/abstracts/26323/nursing-workers-capacity-of-resilience-at-a-psychiatric-hospital-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26323.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">518</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">205</span> Hydroxyapatite-Chitosan Composites for Tissue Engineering Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georgeta%20Voicu">Georgeta Voicu</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Daniela%20Ghitulica"> Cristina Daniela Ghitulica</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreia%20Cucuruz"> Andreia Cucuruz</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Busuioc"> Cristina Busuioc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the field of tissue engineering, the compositional and microstructural features of the employed materials play an important role, with implications on the mechanical and biological behaviour of the medical devices. In this context, the development of apatite - natural biopolymer composites represents a choice of many scientific groups. Thus, hydroxyapatite powders were synthesized by a wet method, namely co-precipitation, starting from high purity reagents (CaO, MgO, and H3PO4). Moreover, the substitution of calcium with magnesium have been approached, in the 5 - 10 wt.% range. Afterward, the phosphate powders were integrated in two types of composites with chitosan, different from morphological point of view. First, 3D porous scaffolds were obtained by a freeze-drying procedure. Second, uniform, compact films were achieved by film casting. The influence of chitosan molecular weight (low, medium and high), as well as apatite powder to polymer ratio (1:1 and 1:2) on the morphological properties, were analysed in detail. In conclusion, the reported biocomposites, prepared by a straightforward route are suitable for bone substitution or repairing applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20reconstruction" title="bone reconstruction">bone reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20scaffolds" title=" composite scaffolds"> composite scaffolds</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxyapatite" title=" hydroxyapatite"> hydroxyapatite</a> </p> <a href="https://publications.waset.org/abstracts/62705/hydroxyapatite-chitosan-composites-for-tissue-engineering-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62705.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">204</span> A Qualitative Study Identifying the Complexities of Early Childhood Professionals' Use and Production of Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Bonetti">Sara Bonetti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of quantitative data to support policies and justify investments has become imperative in many fields including the field of education. However, the topic of data literacy has only marginally touched the early care and education (ECE) field. In California, within the ECE workforce, there is a group of professionals working in policy and advocacy that use quantitative data regularly and whose educational and professional experiences have been neglected by existing research. This study aimed at analyzing these experiences in accessing, using, and producing quantitative data. This study utilized semi-structured interviews to capture the differences in educational and professional backgrounds, policy contexts, and power relations. The participants were three key professionals from county-level organizations and one working at a State Department to allow for a broader perspective at systems level. The study followed Núñez’s multilevel model of intersectionality. The key in Núñez’s model is the intersection of multiple levels of analysis and influence, from the individual to the system level, and the identification of institutional power dynamics that perpetuate the marginalization of certain groups within society. In a similar manner, this study looked at the dynamic interaction of different influences at individual, organizational, and system levels that might intersect and affect ECE professionals’ experiences with quantitative data. At the individual level, an important element identified was the participants’ educational background, as it was possible to observe a relationship between that and their positionality, both with respect to working with data and also with respect to their power within an organization and at the policy table. For example, those with a background in child development were aware of how their formal education failed to train them in the skills that are necessary to work in policy and advocacy, and especially to work with quantitative data, compared to those with a background in administration and/or business. At the organizational level, the interviews showed a connection between the participants’ position within the organization and their organization’s position with respect to others and their degree of access to quantitative data. This in turn affected their sense of empowerment and agency in dealing with data, such as shaping what data is collected and available. These differences reflected on the interviewees’ perceptions and expectations for the ECE workforce. For example, one of the interviewees pointed out that many ECE professionals happen to use data out of the necessity of the moment. This lack of intentionality is a cause for, and at the same time translates into missed training opportunities. Another interviewee pointed out issues related to the professionalism of the ECE workforce by remarking the inadequacy of ECE students’ training in working with data. In conclusion, Núñez’s model helped understand the different elements that affect ECE professionals’ experiences with quantitative data. In particular, what was clear is that these professionals are not being provided with the necessary support and that we are not being intentional in creating data literacy skills for them, despite what is asked of them and their work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20literacy" title="data literacy">data literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20childhood%20professionals" title=" early childhood professionals"> early childhood professionals</a>, <a href="https://publications.waset.org/abstracts/search?q=intersectionality" title=" intersectionality"> intersectionality</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20data" title=" quantitative data"> quantitative data</a> </p> <a href="https://publications.waset.org/abstracts/54181/a-qualitative-study-identifying-the-complexities-of-early-childhood-professionals-use-and-production-of-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54181.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">252</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">203</span> Design of a 4-DOF Robot Manipulator with Optimized Algorithm for Inverse Kinematics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20G%C3%B3mez">S.

This study aims the preparation and characterization of ceramic materials on the basis of TCP (Ca₃(PO₄)₂), within which calcium ions are substituted by magnesium ions (Mg²⁺) in order to improve the regenerative properties of these materials. TCP-Mg material was synthesized by chemical precipitation method using calcium oxide (CaO) and phosphoric acid (H₃PO₄) as precursors. The objective was to obtain powders with different concentrations of Mg in order to analyze the effect of magnesium ions on the physicochemical properties of phosphate ceramics and in vitro degradation in simulated biological fluid (SBF). Ceramic powders were characterized in vitro but also from the compositional and microstructural point of view. TCP_Mg powders were prepared through wet chemical method from calcium oxide (CaO), magnesium oxide nanopowder (MgO < 50 nm particle size (BET) Sigma Aldrich), phosphoric acid (H₃PO₄ - 85 wt.% in H₂O, 99.99% trace metals basis - Sigma Aldrich). In order to determine the quantities of raw materials, calculations were performed to obtain HAp with Ca/P ratio of 1.5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20regeneration" title="bone regeneration">bone regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20substitution" title=" magnesium substitution"> magnesium substitution</a>, <a href="https://publications.waset.org/abstracts/search?q=tricalcium%20phosphate" title=" tricalcium phosphate"> tricalcium phosphate</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title=" tissue engineering"> tissue engineering</a> </p> <a href="https://publications.waset.org/abstracts/62756/synthesis-of-tricalcium-phosphate-substituted-with-magnesium-ions-for-bone-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62756.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">201</span> Ecosystem Model for Environmental Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Schreiner">Cristina Schreiner</a>, <a href="https://publications.waset.org/abstracts/search?q=Romeo%20Ciobanu"> Romeo Ciobanu</a>, <a href="https://publications.waset.org/abstracts/search?q=Marius%20Pislaru"> Marius Pislaru</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to build a system based on fuzzy models that can be implemented in the assessment of ecological systems, to determine appropriate methods of action for reducing adverse effects on environmental and implicit the population.

Nowadays, psychoanalytic theory is applied to numerous fields. One of them is literature. Literary criticism has put into practice the basis of Freud’s idea to analyze literary works. This essay is about the analysis of Edgar A. Poe’s short story ‘The Tell-Tale Heart,’ under the lens of Freud’s psychoanalytical perspective. In 1919, it was published ‘Das Unheimliche’ (The Uncanny) by Freud. On this article, the famous Austrian psychoanalyst showed his explanations about what he called ‘the uncanny,’ and its relation to the human unconscious. In this paper, Freud’s famous article has been used to analyze Poe’s short story ‘The Tell-Tale Heart,’ and to find the analogies that exist between Poe’s macabre short story and Freud’s theory of ‘the uncanny.’ <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=psychoanalysis" title="psychoanalysis">psychoanalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=theory%20of%20the%20unconscious" title=" theory of the unconscious"> theory of the unconscious</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20uncanny" title=" the uncanny"> the uncanny</a>, <a href="https://publications.waset.org/abstracts/search?q=unheimlich" title=" unheimlich"> unheimlich</a> </p> <a href="https://publications.waset.org/abstracts/71692/a-psychoanalytical-approach-to-edgar-a-poes-short-story-the-tell-tale-heart" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71692.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">644</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">198</span> Neuron Dynamics of Single-Compartment Traub Model for Hardware Implementations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20C.%20Moctezuma">J.

The diagnosis is related to the interpretation of the data, findings and the relevant information, to determine problems, causes, or the simple state and behavior of a process, without including a solution to the problems detected. The objective of this work is to identify the necessary stages to diagnose the logistic processes in a metalworking company, from the literary revision of different disciplines. A total of 62 articles were chosen to identify, through bibliometric analysis, the most cited articles, as well as the most frequent authors and journals. The results allowed to identify the two fundamental stages in the diagnostic process: a primary phase (general) based on the logical subjectivity of the knowledge of the person who evaluates, and the secondary phase (specific), related to the interpretation of the results, findings or data. Also, two phases were identified, one related to the definition of the scope of the actions to be developed and the other, as an initial description of what was observed in the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business" title="business">business</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnostic" title=" diagnostic"> diagnostic</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a> </p> <a href="https://publications.waset.org/abstracts/99714/diagnosis-of-logistics-processes-bibliometric-review-and-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99714.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">195</span> Phytoplankton Community Composition in Laguna de Terminos, Mexico, and Its Relationship to Environmental Variables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Nunez%20L.">Enrique Nunez L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20%20Cortes%20L."> Maria Cortes L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Laffon%20L."> Sandra Laffon L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20M.%20Cupul%20V."> Ana M.

Six sites inside the tropical Terminos Lagoon were sampled in order to determine abundances and ecological indexes for phytoplankton from May to December 2017. Water samples were also collected to determine the values of pigments, nutrients, and water solids. Results showed that the composition and abundance of the phytoplankton community were influenced by physicochemical factors, nutrients, water solids, and climate seasons. Sixty-six species were identified as potential HAB producers (44.29% from total). However, abundances were not related to the occurrence of HAB during the study. Multidimensional ANOVA indicated no significant differences between sites while some months revealed significant differences. The canonical analysis suggested that environmental variables explained 49% of community variation of potential phytoplankton species producers of HAB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phytoplankton" title="phytoplankton">phytoplankton</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=lagoon" title=" lagoon"> lagoon</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a> </p> <a href="https://publications.waset.org/abstracts/122868/phytoplankton-community-composition-in-laguna-de-terminos-mexico-and-its-relationship-to-environmental-variables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122868.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">194</span> Main Cause of Children's Deaths in Indigenous Wayuu Community from Department of La Guajira: A Research Developed through Data Mining Use</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isaura%20Esther%20Solano%20N%C3%BA%C3%B1ez">Isaura Esther Solano Núñez</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Suarez"> David Suarez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this research is to discover what causes death in children of the Wayuu community, and deeply analyze those results in order to take corrective measures to properly control infant mortality. We consider important to determine the reasons that are producing early death in this specific type of population, since they are the most vulnerable to high risk environmental conditions. In this way, the government, through competent authorities, may develop prevention policies and the right measures to avoid an increase of this tragic fact. The methodology used to develop this investigation is data mining, which consists in gaining and examining large amounts of data to produce new and valuable information. Through this technique it has been possible to determine that the child population is dying mostly from malnutrition. In short, this technique has been very useful to develop this study; it has allowed us to transform large amounts of information into a conclusive and important statement, which has made it easier to take appropriate steps to resolve a particular situation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=malnutrition" title="malnutrition">malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical" title=" analytical"> analytical</a>, <a href="https://publications.waset.org/abstracts/search?q=descriptive" title=" descriptive"> descriptive</a>, <a href="https://publications.waset.org/abstracts/search?q=population" title=" population"> population</a>, <a href="https://publications.waset.org/abstracts/search?q=Wayuu" title=" Wayuu"> Wayuu</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous" title=" indigenous"> indigenous</a> </p> <a href="https://publications.waset.org/abstracts/86076/main-cause-of-childrens-deaths-in-indigenous-wayuu-community-from-department-of-la-guajira-a-research-developed-through-data-mining-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86076.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">193</span> Competences for Learning beyond the Academic Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Galv%C3%A1n-Fern%C3%A1ndez">Cristina Galván-Fernández </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Students differentiate the different contexts of their lives as well as employment, hobbies or studies.

This article analyzes the production process of a hot asphalt manufacturing company from an administrative and technical perspective. Three main phases were analyzed, the first phase was related to the determination of the risk priority number of the main operations in asphalt mix production process by an FMEA (Failure Mode Effects Analysis), in the second phase the Value Stream Mapping (VSM) of the production line was performed and in the third phase a SWOT (Strengths, Weaknesses Opportunities, Threats) matrix was constructed. Among the most valued failure modes were the lack training of workers in occupational safety and health issues, the lack of signaling and classification of granulated material, and the overweight of vehicles loaded. The analysis of the results in the three phases agree on the importance of training operational workers, improve communication with external actors in order to minimize delays in material orders and strengthen control suppliers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphalt" title="asphalt">asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title=" lean manufacturing"> lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a> </p> <a href="https://publications.waset.org/abstracts/99710/application-of-lean-manufacturing-tools-in-hot-asphalt-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99710.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">191</span> Argumentative and Enunciative Analysis of Spanish Political Discourse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Diez">Cristina Diez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most important challenges of discourse analysis is to find the linguistic mechanisms of subjectivity. The present article aims to raise the need for an argumentative and enunciative analysis to reach the subjective tissue of language. The intention is to prove that the instructions inscribed in the own language are those that indicate how a statement is to be interpreted and that the argumentative value is implied at the semantic level. For that, the theory of argumentation from Ducrot and Anscombre will be implemented. First, a reflection on the study about subjectivity and enunciation in language will be exposed, followed by concrete proposals on the linguistic mechanisms that speakers use either consciously or unconsciously, to finally focus on those argumentative tools that political discourse uses in order to influence the audience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=argumentation" title="argumentation">argumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=enunciation" title=" enunciation"> enunciation</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse%20analysis" title=" discourse analysis"> discourse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=subjectivity" title=" subjectivity"> subjectivity</a> </p> <a href="https://publications.waset.org/abstracts/81219/argumentative-and-enunciative-analysis-of-spanish-political-discourse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81219.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">190</span> D6tions: A Serious Game to Learn Software Engineering Process and Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hector%20G.%20Perez-Gonzalez">Hector G.

To improve this process, researchers have proposed merely illustrative techniques in the classroom, such as topic presentations and dynamics between students on one side or attempts to involve students in real projects with companies and institutions to bring them to a real software development problem on the other hand. Simulators and serious games have been used as auxiliary tools to introduce students to topics that are too abstract when these are presented in the traditional way. Most of these tools cover a limited area of the huge software engineering scope. To address this problem, we have developed D6tions, an educational serious game that simulates the software engineering process and is designed to experiment the different stages a software engineer (playing roles as project leader or as a developer or designer) goes through, while participating in a software project.

ERPs were recorded while seventeen HMA and seventeen LMA individuals performed the verification task. Groups did not differ in trait anxiety or gender distribution. Participants were presented with two-digit additions and were asked to decide whether the proposed solution was correct or incorrect. Behavioral data showed a significant Carrying x Proposed solution x Group interaction for accuracy, showing that carrying additions were more error prone than non-carrying ones for both groups, although the difference non-carrying minus carrying was larger for the HMA group. As for ERPs, a P2 component larger in HMA individuals than in their LMA peers was found both for carrying and non-carrying additions. The P2 was followed by a sustained negative slow wave at parietal positions. Because the negative slow waves are thought to reflect the updating of working memory, these results give support to the relationship among working memory, math performance and math anxiety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=math%20anxiety" title="math anxiety">math anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=carrying" title=" carrying"> carrying</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20memory" title=" working memory"> working memory</a>, <a href="https://publications.waset.org/abstracts/search?q=P2" title=" P2 "> P2 </a> </p> <a href="https://publications.waset.org/abstracts/25642/math-anxiety-effects-on-complex-addition-an-erp-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25642.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">447</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">187</span> Modular Probe for Basic Monitoring of Water and Air Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20Calvillo%20T%C3%A9llez">Andrés Calvillo Téllez</a>, <a href="https://publications.waset.org/abstracts/search?q=Marianne%20Mart%C3%ADnez%20Zanzarric"> Marianne Martínez Zanzarric</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Cruz%20N%C3%BA%C3%B1ez%20P%C3%A9rez"> José Cruz Núñez Pérez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A modular system that performs basic monitoring of both water and air quality is presented. Monitoring is essential for environmental, aquaculture, and agricultural disciplines, where this type of instrumentation is necessary for data collection. The system uses low-cost components, which allows readings close to those with high-cost probes. The probe collects readings such as the coordinates of the geographical position, as well as the time it records the target parameters of the monitored. The modules or subsystems that make up the probe are the global positioning (GPS), which shows the altitude, latitude, and longitude data of the point where the reading will be recorded, a real-time clock stage, the date marking the time, the module SD memory continuously stores data, data acquisition system, central processing unit, and energy. The system acquires parameters to measure water quality, conductivity, pressure, and temperature, and for air, three types of ammonia, dioxide, and carbon monoxide gases were censored. The information obtained allowed us to identify the schedule of modification of the parameters and the identification of the ideal conditions for the growth of microorganisms in the water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calibration" title="calibration">calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=conductivity" title=" conductivity"> conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=datalogger" title=" datalogger"> datalogger</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20clock" title=" real time clock"> real time clock</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/145653/modular-probe-for-basic-monitoring-of-water-and-air-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145653.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">103</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">186</span> Formative Assessment in an Introductory Python Programming Course</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Jos%C3%A9%20N%C3%BA%C3%B1ez-Ruiz">María José Núñez-Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20%C3%81lvarez-Gonz%C3%A1lez"> Luis Álvarez-González</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristian%20Olivares-Rodriguez"> Cristian Olivares-Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Lazo-Letelier"> Benjamin Lazo-Letelier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper begins with some concept of formative assessment and the relationship with learning objective: contents objectives, processes objectives, and metacognitive objectives. Two methodologies are describes Evidence-Based teaching and Question Drive Instruction. To do formative assessments in larges classes a Classroom Response System (CRS) is needed. But most of CRS use only Multiple Choice Questions (MCQ), True/False question, or text entry; however, this is insufficient to formative assessment. To do that a new CRS, call FAMA was developed. FAMA support six types of questions: Choice, Order, Inline choice, Text entry, Associated, and Slider. An experiment participated in 149 students from four engineering careers. For results, Kendall's Range Correlation Analysis and descriptive analysis was done. In conclusion, there is a strong relation between contents question, process questions (ask in formative assessment without a score) and metacognitive questions, asked in summative assessment. As future work, the lecturer can do personalized teaching, because knows the behavior of all students in each formative assessment <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Python%20language" title="Python language">Python language</a>, <a href="https://publications.waset.org/abstracts/search?q=formative%20assessment" title=" formative assessment"> formative assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=classroom%20response%20systems" title=" classroom response systems"> classroom response systems</a>, <a href="https://publications.waset.org/abstracts/search?q=evidence-Based%20teaching" title=" evidence-Based teaching"> evidence-Based teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=question%20drive%20instruction" title=" question drive instruction"> question drive instruction</a> </p> <a href="https://publications.waset.org/abstracts/120270/formative-assessment-in-an-introductory-python-programming-course" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120270.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">185</span> Bowen Ratio in Western São Paulo State, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elaine%20Cristina%20Barboza">Elaine Cristina Barboza</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Jaschke%20Machado"> Antonio Jaschke Machado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses micrometeorological aspects of the urban climate in three cities in Western São Paulo State: Presidente Prudente, Assis, and Iepê.

Estimates of convective fluxes showed that the Bowen ratio was an indicator of the local climate and that its magnitude varied between 0.3 and 0.7. Maximum values for the Bowen ratio occurred earlier in Iepê (11:00 am) than in Presidente Prudente (4:00 pm).

The objective of this study was to find out if there are differences in receptive vocabulary between adolescence and adulthood. In this research, 30 people with DS between 11 and 40 years old, divided into two age ranges (11-18; 19 - 30) and matched in mental age, were evaluated through the Peabody Vocabulary Test. The results show significant differences between both groups in favor of the group with the oldest chronological age and a direct correlation between chronological age and receptive vocabulary development, regardless of mental age. These data support the natural evolution of the passive lexicon in people with DS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=down%20syndrome" title="down syndrome">down syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=language" title=" language"> language</a>, <a href="https://publications.waset.org/abstracts/search?q=receptive%20vocabulary" title=" receptive vocabulary"> receptive vocabulary</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=adults" title=" adults"> adults</a> </p> <a href="https://publications.waset.org/abstracts/141514/receptive-vocabulary-development-in-adolescents-and-adults-with-down-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">183</span> Fractional Order Controller Design for Vibration Attenuation in an Airplane Wing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Birs%20Isabela">Birs Isabela</a>, <a href="https://publications.waset.org/abstracts/search?q=Muresan%20Cristina"> Muresan Cristina</a>, <a href="https://publications.waset.org/abstracts/search?q=Folea%20Silviu"> Folea Silviu</a>, <a href="https://publications.waset.org/abstracts/search?q=Prodan%20Ovidiu"> Prodan Ovidiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p class="Abstract" style="text-indent:10.2pt;line-height:normal"><span lang="EN-US">The wing is one of the most important parts of an airplane because it ensures stability, sustenance and maneuverability of the airplane.

Thus, there is a need of models for assessing the quality of airport services. Because of this, the main objective of this work is to propose a model for the evaluation of quality attributes in airport services. To this end, we used the method composed by literature review and interview. Structured a working method composed by 5 steps, which resulted in a model to evaluate the quality of airport services, consisting of 8 dimensions and 45 attributes. Was used as base for model definition the process mapping of boarding and landing processes of passengers and luggage. As a contribution of this work is the integration of management process with structuring models to assess the quality of services in airport environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20airport%20services" title="quality airport services">quality airport services</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20for%20identification%20of%20attributes%20quality" title=" model for identification of attributes quality"> model for identification of attributes quality</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20transport" title=" air transport"> air transport</a>, <a href="https://publications.waset.org/abstracts/search?q=passenger" title=" passenger"> passenger</a> </p> <a href="https://publications.waset.org/abstracts/24893/model-for-assessment-of-quality-airport-services" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24893.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">535</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">180</span> Assessing the Antimicrobial Activity of Chitosan Nanoparticles by Fluorescence-Labeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laidson%20P.%20Gomes">Laidson P.

Confocal laser scanning micrographs (CLSM) were used to observe the interaction between <em>E. coli </em>suspensions mixed with FITC-labeled chitosan polymers and nanoparticles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chitosan%20nanoparticles" title="chitosan nanoparticles">chitosan nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20light%20scattering" title=" dynamic light scattering"> dynamic light scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=zeta%20potential" title=" zeta potential"> zeta potential</a>, <a href="https://publications.waset.org/abstracts/search?q=confocal%20microscopy" title=" confocal microscopy"> confocal microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title=" antibacterial activity"> antibacterial activity</a> </p> <a href="https://publications.waset.org/abstracts/84752/assessing-the-antimicrobial-activity-of-chitosan-nanoparticles-by-fluorescence-labeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84752.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">501</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">179</span> Key Factors for a Smart City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Christina%20Suciu">Marta Christina Suciu</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Andreea%20Florea"> Cristina Andreea Florea</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to highlight the relevance of building smart cities in the context of regional development and to analyze the important factors that make a city smart. These cities could be analyzed through the perspective of environment quality, the socio-cultural condition, technological applications and innovations, the vitality of the economic environment and public policies. Starting with these five sustainability domains, we will demonstrate the hypothesis that smart cities are the engine of the regional development. The aim of this paper is to assess the implications of smart cities, in the context of sustainable development, analyzing the benefits of developing creative and innovative cities. Regarding the methodology, it is used the systemic, logical and comparative analysis of important literature and data, also descriptive statistics and correlation analysis. In conclusion, we will define a direction on the regional development and competitiveness increasing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creativity" title="creativity">creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20development" title=" regional development"> regional development</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=triple%20helix" title=" triple helix "> triple helix </a> </p> <a href="https://publications.waset.org/abstracts/35665/key-factors-for-a-smart-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35665.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">489</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">178</span> Comparison of Two Transcranial Magnetic Stimulation Protocols on Spasticity in Multiple Sclerosis - Pilot Study of a Randomized and Blind Cross-over Clinical Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Cristina%20da%20Silva%20Reis">Amanda Cristina da Silva Reis</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Paulino%20Ven%C3%A2ncio"> Bruno Paulino Venâncio</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Theada%20Ferreira"> Cristina Theada Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Fialho%20do%20Prado"> Andrea Fialho do Prado</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucimara%20Guedes%20dos%20Santos"> Lucimara Guedes dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Aline%20de%20Souza%20Gravat%C3%A1"> Aline de Souza Gravatá</a>, <a href="https://publications.waset.org/abstracts/search?q=Larissa%20Lima%20Gon%C3%A7alves"> Larissa Lima Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabella%20Aparecida%20Ferreira%20Moretto"> Isabella Aparecida Ferreira Moretto</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Carlos%20Ferrari%20Corr%C3%AAa"> João Carlos Ferrari Corrêa</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernanda%20Ishida%20Corr%C3%AAa"> Fernanda Ishida Corrêa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To compare two protocols of Transcranial Magnetic Stimulation (TMS) on quadriceps muscle spasticity in individuals diagnosed with Multiple Sclerosis (MS). Method: Clinical, crossover study, in which six adult individuals diagnosed with MS and spasticity in the lower limbs were randomized to receive one session of high-frequency (≥5Hz) and low-frequency (≤ 1Hz) TMS on motor cortex (M1) hotspot for quadriceps muscle, with a one-week interval between the sessions. To assess the spasticity was applied the Ashworth scale and were analyzed the latency time (ms) of the motor evoked potential (MEP) and the central motor conduction time (CMCT) of the bilateral quadriceps muscle. Assessments were performed before and after each intervention. The difference between groups was analyzed using the Friedman test, with a significance level of 0.05 adopted. Results: All statistical analyzes were performed using the SPSS Statistic version 26 programs, with a significance level established for the analyzes at p<0.05. Shapiro Wilk normality test. Parametric data were represented as mean and standard deviation for non-parametric variables, median and interquartile range, and frequency and percentage for categorical variables. There was no clinical change in quadriceps spasticity assessed using the Ashworth scale for the 1 Hz (p=0.813) and 5 Hz (p= 0.232) protocols for both limbs. Motor Evoked Potential latency time: in the 5hz protocol, there was no significant change for the contralateral side from pre to post-treatment (p>0.05), and for the ipsilateral side, there was a decrease in latency time of 0.07 seconds (p<0.05 ); for the 1Hz protocol there was an increase of 0.04 seconds in the latency time (p<0.05) for the contralateral side to the stimulus, and for the ipsilateral side there was a decrease in the latency time of 0.04 seconds (p=<0.05), with a significant difference between the contralateral (p=0.007) and ipsilateral (p=0.014) groups. Central motor conduction time in the 1Hz protocol, there was no change for the contralateral side (p>0.05) and for the ipsilateral side (p>0.05). In the 5Hz protocol for the contralateral side, there was a small decrease in latency time (p<0.05) and for the ipsilateral side, there was a decrease of 0.6 seconds in the latency time (p<0.05) with a significant difference between groups (p=0.019). Conclusion: A high or low-frequency session does not change spasticity, but it is observed that when the low-frequency protocol was performed, there was an increase in latency time on the stimulated side, and a decrease in latency time on the non-stimulated side, considering then that inhibiting the motor cortex increases cortical excitability on the opposite side. <p
