SARS-CoV-2 (COVID-19) pandemic was identified in January 2020 in China, in the city of Wuhan. The increase in the number of cases over the following months was responsible for the restructuring of hospitals and departments in order to accommodate admissions related to COVID-19. Essential services, such as trauma, had to readapt to maintain their functionality and thus guarantee quick and safe access in case of an emergency. Objectives: This study describes the impact of COVID-19 on a Level III Trauma Center and particularly on the clinical management of hospitalized patients with spine injuries. Study Design & Methods: This is a retrospective cohort study whose results were obtained through the medical records of patients with spine injuries who underwent surgical intervention in the years 2019 and 2020 (period from March 1st to December 31st). A comparison between the two groups was made. In the study patients with injuries in the context of trauma were included who underwent surgery in the periods previously described. Patients hospitalized with a spine injury in a non-traumatic context and/or were not surgically treated were excluded. Results: In total, 137 patients underwent trauma spine surgery of which 71 in 2019 (51.8%) were without significant differences in intergroup comparisons. The most frequent injury mechanism in 2019 was motor vehicle crash (47.9%) compared to 2020 which was of a person falling from a height between 2-4 meters (37.9%). Cervical trauma was reported to be the most frequent spine injury in both years. There was a significant decrease in the need for intensive care in 2020, 51.4% vs 30.3%, p = .015 and the number of complications was also lower in 2020 (1.35% vs 0.98%), including the number of deaths, being the difference marginally significant. There were no significant differences regarding time for presentation to surgery or in the total days of hospitalization. Conclusions: The restructuring made in the trauma unit at a Level III Trauma Center in the context of the current COVID-19 pandemic was effective, with no significant differences between the years of 2019 vs 2020 when compared with the time for presentation to surgery or the number of days of hospitalization. It was also found that lockdown rules in 2020 were probably responsible for the decrease in the number of road traffic accidents, which justifies a significant decrease in the need for intensive care as well as in the number of complications in patients hospitalized in the context of spine trauma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trauma" title="trauma">trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=spine" title=" spine"> spine</a>, <a href="https://publications.waset.org/abstracts/search?q=impact" title=" impact"> impact</a>, <a href="https://publications.waset.org/abstracts/search?q=covid-19" title=" covid-19"> covid-19</a> </p> <a href="https://publications.waset.org/abstracts/138436/the-covid-pandemic-at-a-level-iii-trauma-center-challenges-in-the-management-of-the-spine-trauma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138436.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">256</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">119</span> The Importance of Mental Health Literacy: Interventions in a Psychiatry Service of Hospital José Joaquim Fernandes, Portugal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Mangas">Mariana Mangas</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaroslava%20Martins"> Yaroslava Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Charraz"> Ana Charraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Matos%20Pires"> Ana Matos Pires</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Health literacy empowers people of knowledge, motivation and skills to access, understand, evaluate and mobilize information relating to health. Although the benefits of public knowledge of physical disease are widely accepted, knowledge about mental disorder has been compatibly neglected. Nowadays there is considerably evidence that literacy is of great importance for the promotion of health and prevention of mental illness. Objective: Disclosure the concept and importance of mental health literacy and introduce the literacy program of Psychiatry Service of Hospital José Joaquim Fernandes. Methodology: A search was conducted on PubMed, using keywords “literacy” and “mental health”. A description of mental health literacy interventions implemented on Psychiatry Service of Hospital José Joaquim Fernandes was performed, namely, psychoeducation programs for depression and bipolar disorder. Results and discussion: Health literacy enables patient to be able to actively participate in his treatment. The improving of mental health literacy can promote early identification of mental disorders, improve treatment results, increase the use of health services and allow the community to take action to achieve better mental health. Psychoeducation is very useful in improving the course of disease and in reducing the number of episodes and hospitalizations. Bipolar patients who received psychoeducation and pharmacotherapy have no relapses during the program and last year. Conclusion: Mental health literacy is not simply a matter of having knowledge, rather, it is knowledge linked to action which can benefit mental health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title="mental health">mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=literacy" title=" literacy"> literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoeducation" title=" psychoeducation"> psychoeducation</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=empowerment" title=" empowerment"> empowerment</a> </p> <a href="https://publications.waset.org/abstracts/58750/the-importance-of-mental-health-literacy-interventions-in-a-psychiatry-service-of-hospital-jose-joaquim-fernandes-portugal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58750.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">547</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">118</span> Melancholia, Nostalgia: Bernardo Soares after Fernando Pessoa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20de%20F%C3%A1tima%20Lambert">Maria de Fátima Lambert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bernardo Soares is one of Fernando Pessoa' several heteronyms (and "half-heteronyms"). Perhaps the one that brought together the majority of his qualities and characters of self-identity within the famous inner-persona-alter-diversity. The Book of Disquiet by Bernardo Soares was released in 1983, consisting of ontological remarks caught by an obsessive inquiring about self-existence. The book became a highly valuable substance when focusing upon the philosophical grounds of Pessoa's aesthetics. For sure, we cannot consider a single aesthetic, admitting that each heteronym has its own particular one, developed after different principles and convictions. Regarding Bernardo Soares, his thought arises from sequenced self-clues expressing peculiar existential doubtless presented as certainties -and vice-versa. His written self-search-images are reported, molding the painful awareness of existence through the discredited tolerance of any conclusive dialogue with others. Given the nature of Soares’ [maybe] unfinished writings, it is obvious that he headed far from his self-insurance-capsule: the office, bedroom, or even the walkscapes through Lisbon. The idea of travel/journey is one of the most relevant when recognizing his profound - although undercover - anguish as melancholy and nostalgia. In Bernardo Soares, Aesthetics is taken agonizingly, grounded upon discreet poetic phraseology and terms. His poetical awareness developed compulsive titles such "Aesthetics of Indifference", "Aesthetics of Discouragement". Soares' Aesthetics emerges directly from oneself, understanding art as inner acts and living experienced issues. Art is not freed from the intellectual expression of oneself emotions. The Disquiet Book is an existential nightmare nourished by everyday life, single written thoughts, balanced by melancholia, nostalgia, and distress. One might wonder if it was dreams that guided his fictional literary persona or the narrow facts of life itself. Along with his endless disquiet writing, Pessoa’s semi-heteronymous traveled without physically going anywhere. The complexity of inner existence is fulfilled by lonely mental walks and travels, as in two texts titled The Never Accomplished Journey. Although we also can consider other fragments, these are the deepest reflections about travelling. Let’s recall that Fernando Pessoa’s ortonyms writings -poems and essays- also addressed this issue from a philosophical perspective. We believe that this theme is one of the meaningful concepts for featuring the main principles of his aesthetics. As we know, Fernando Pessoa did not travel to foreign countries (or in Portugal), except for the journey, with his family, from Lisbon to South Africa (as a child) and, some years later, the return back to Lisbon. One may wonder why the poet never undertook other journeys. Maybe due to a disbelief in moving away from his comfort zone or due to the fear of becoming addicted to endless travels and the loss of his convenient self-closeness. In The Book of Disquiet, the poet shared his internal visions of the outer world but mainly visualizing his deepest enigmas and experiences -so strongly incorporated into reality and fiction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aesthetic%20principles" title="aesthetic principles">aesthetic principles</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernardo%20Soares" title=" Bernardo Soares"> Bernardo Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Pessoa" title=" Fernando Pessoa "> Fernando Pessoa </a>, <a href="https://publications.waset.org/abstracts/search?q=melancholia" title=" melancholia"> melancholia</a>, <a href="https://publications.waset.org/abstracts/search?q=nostalgia" title=" nostalgia"> nostalgia</a>, <a href="https://publications.waset.org/abstracts/search?q=non-accomplished%20travel" title=" non-accomplished travel"> non-accomplished travel</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Book%20of%20Disquiet" title=" The Book of Disquiet"> The Book of Disquiet</a> </p> <a href="https://publications.waset.org/abstracts/138528/melancholia-nostalgia-bernardo-soares-after-fernando-pessoa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138528.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">130</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">117</span> Low-Power Digital Filters Design Using a Bypassing Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Brito%20Bezerra">Thiago Brito Bezerra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a novel approach to reduce power consumption of digital filters based on dynamic bypassing of partial products in their multipliers.

Alkaline leaching of lithium concentrates allows the establishment of a production diagram avoiding most of the environmental drawbacks that are associated with the usage of acid reagents. The tested processes involve a pretreatment by digestion at high temperatures with additives, followed by leaching at hot atmospheric pressure. The solutions obtained must be compatible with solutions from the leaching of spodumene concentrates, allowing the development of a common treatment diagram, an important accomplishment for the feasible exploitation of Portuguese resources.

In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addition of the traditional mordanting agents and then submitted to wash fastness analysis. The resulting dyed fabrics were evaluated for color fastness. It was found that wash fastness of dyed fabrics was very good to cotton and excellent to nylon and wool. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eucalyptus" title="eucalyptus">eucalyptus</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20dye" title=" natural dye"> natural dye</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20fibers" title=" textile fibers"> textile fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=wash%20fastness" title=" wash fastness"> wash fastness</a> </p> <a href="https://publications.waset.org/abstracts/25681/wash-fastness-of-textile-fibers-dyed-with-natural-dye-from-eucalyptus-wood-steaming-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25681.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">614</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">112</span> Enhanced Kinetic Solubility Profile of Epiisopiloturine Solid Solution in Hipromellose Phthalate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanda%20C.%20Q.%20M.%20Vieira">Amanda C.

EPI has demonstrated promising schistosomicidal, leishmanicide, anti-inflammatory and antinociceptive activities, according to in vitro studies that have been carried out since 2009. However, this molecule shows poor aqueous solubility, which represents a problem for the release of the drug candidate and its absorption by the organism. The purpose of the present study is to investigate the extent of enhancement of kinetic solubility of a solid solution (SS) of EPI in hipromellose phthalate HP-55 (HPMCP), an enteric polymer carrier. SS was obtained by the solvent evaporation methodology, using acetone/methanol (60:40) as solvent system. Both EPI and polymer (drug loading 10%) were dissolved in this solvent until a clear solution was obtained, and then dried in oven at 60ºC during 12 hours, followed by drying in a vacuum oven for 4 h. The results show a considerable modification in the crystalline structure of the drug candidate. For instance, X-ray diffraction (XRD) shows a crystalline behavior for the EPI, which becomes amorphous for the SS. Polarized light microscopy, a more sensitive technique than XRD, also shows completely absence of crystals in SS sample. Differential Scanning Calorimetric (DSC) curves show no signal of EPI melting point in SS curve, indicating, once more, no presence of crystal in this system. Interaction between the drug candidate and the polymer were found in Infrared microscopy, which shows a carbonyl 43.3 cm-1 band shift, indicating a moderate-strong interaction between them, probably one of the reasons to the SS formation. Under sink conditions (pH 6.8), EPI SS had its dissolution performance increased in 2.8 times when compared with the isolated drug candidate. EPI SS sample provided a release of more than 95% of the drug candidate in 15 min, whereas only 45% of EPI (alone) could be dissolved in 15 min and 70% in 90 min. Thus, HPMCP demonstrates to have a good potential to enhance the kinetic solubility profile of EPI. Future studies to evaluate the stability of SS are required to conclude the benefits of this system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epiisopiloturine" title="epiisopiloturine">epiisopiloturine</a>, <a href="https://publications.waset.org/abstracts/search?q=hipromellose%20phthalate%20HP-55" title=" hipromellose phthalate HP-55"> hipromellose phthalate HP-55</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceuticaltechnology" title=" pharmaceuticaltechnology"> pharmaceuticaltechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility" title=" solubility"> solubility</a> </p> <a href="https://publications.waset.org/abstracts/25673/enhanced-kinetic-solubility-profile-of-epiisopiloturine-solid-solution-in-hipromellose-phthalate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25673.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">607</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">111</span> Sustainable Solutions for Urban Problems: Industrial Container Housing for Endangered Communities in Maranhao, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helida%20Thays%20Gomes%20Soares">Helida Thays Gomes Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Conceicao%20De%20Maria%20Pinheiro%20Correia"> Conceicao De Maria Pinheiro Correia</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiano%20Maciel%20Soares"> Fabiano Maciel Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Kleymer%20Silva"> Kleymer Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is great discussion around populational increase in urban areas of the global south, and, consequently, the growth of inappropriate housing and the different ways humans have found to solve housing problems around the world. Sao Luís, the capital of the state of Maranhao is a good example. The 1.6 million inhabitant metropole is a colonial tropical city that shelters 22% of the population of Maranhão, brazilian state that still carries the scars of slavery in past centuries. In 2016, Brazilian Institute of Geography and Statistic found that 20% of Maranhão’s inhabitants were living in houses with external walls made of non-durable materials, like recycled wood, cardboard or soil. Out of this problematic, this study aims to propose interventions not only in the physical structure of irregular housing, but also to serve as a guide to intervene in the way eco-friendly, communitarian housing is seen by extreme poor zones inside metropolitan regions around big cities in the global south. The adaptation and reuse of industrial containers from the Harbor of Itaqui for housing is also an aim of the project. The great volume of discarded industrial containers may be an opportunity to solve housing deficit in the city. That way, through field research in São Luís’ neighborhoods mostly occupied by inappropriate housing, the study intends to raise ethnographical and physical values that help to shape new uses of industrial containers and recycled building materials, bringing the community into the process of shaping new-housing for local housing programs, changing the mindset of a concrete/brick model of building. The study used a general feasibility analysis of local engineers regarding strength of the locally used container for construction purposes, and also researched in-loco the current impressions of risky areas inhabitants of housing, traditional housing and the role they played as city shapers, evaluating their perceptions of what means to live and how their houses represent their personality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=container%20housing" title="container housing">container housing</a>, <a href="https://publications.waset.org/abstracts/search?q=civil%20construction" title=" civil construction"> civil construction</a>, <a href="https://publications.waset.org/abstracts/search?q=housing%20deficit" title=" housing deficit"> housing deficit</a>, <a href="https://publications.waset.org/abstracts/search?q=participatory%20design" title=" participatory design"> participatory design</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/105723/sustainable-solutions-for-urban-problems-industrial-container-housing-for-endangered-communities-in-maranhao-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105723.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">191</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">110</span> Proposal of Innovative Risk Assessment of Ergonomic Factors in the Production of Jet Engines Using AHP (Analytic Hierarchy Process)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Cristiano%20Pereira">Jose Cristiano Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilson%20Brito%20Alves%20Lima"> Gilson Brito Alves Lima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ergonomics is a key factor affecting the operational safety and quality in the aircraft engine manufacturing industry and evidence shows that the lack of attention to it can increase the risk of accidents.

Market-based and labor environment explanations have received particular attention, both to explain the reasons for a growth in this compensation and to indicate that they may increase agency problems rather than mitigate them. In this sense, labor forces, especially related to the market for executives, contribute to defining the terms of compensation packages and represent a significant external control mechanism to moderate agency problems, but may be of little effect if the executives are entrenched and concentrate enough power to have a say in his/her compensation. Based on a five-year data panel related to executive compensation in 250 listed companies in Brazil, we examine whether the economic recession in the last two years produced any impact in this compensation, controlling for the sector and level of governance of the company. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agency%20problems" title="agency problems">agency problems</a>, <a href="https://publications.waset.org/abstracts/search?q=executive%20compensation" title=" executive compensation"> executive compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20mechanisms" title=" control mechanisms"> control mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title=" corporate governance"> corporate governance</a> </p> <a href="https://publications.waset.org/abstracts/81769/effects-of-an-economic-recession-on-executive-compensation-a-panel-analysis-of-listed-companies-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81769.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">445</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">108</span> Computational Tool for Surface Electromyography Analysis; an Easy Way for Non-Engineers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabiano%20Araujo%20Soares">Fabiano Araujo Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Sauro%20Emerick%20Salomoni"> Sauro Emerick Salomoni</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Paulo%20Lima%20da%20Silva"> Joao Paulo Lima da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Luiz%20Moura"> Igor Luiz Moura</a>, <a href="https://publications.waset.org/abstracts/search?q=Adson%20Ferreira%20da%20Rocha"> Adson Ferreira da Rocha </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a tool developed in the Matlab platform.

Maternal sleep deprivation can trigger or aggravate psychosomatic problems such as depression, anxiety and stress that can directly influence maternal safety, with consequences for the baby's and mother's sleep. Such conditions can affect the family's quality of life and child development. Objective: To correlate maternal security with maternal state anxiety scores and the mother's and baby's total sleep time. Method: Cross-sectional study carried out with 96 mothers of babies aged 10 to 24 months, accompanied by nursing professionals linked to a Federal University in Northeast Brazil. Study variables were maternal security, maternal state anxiety scores, infant latency and sleep time, and total nocturnal sleep time of mother and infant. Maternal safety was calculated using a four-point Likert scale (1=not at all safe, 2=somewhat safe, 3=very safe, 4=completely safe). Maternal anxiety was measured by State-Trait Anxiety Inventory, state-anxiety subscale whose scores vary from 20 to 80 points, and the higher the score, the higher the anxiety levels. Scores below 33 are considered mild; from 33 to 49, moderate and above 49, high. As for the total nocturnal sleep time, values between 7-9 hours of sleep were considered adequate for mothers, and values between 9-12 hours for the baby, according to the guidelines of the National Sleep Foundation. For the sleep latency time, a time equal to or less than 20 min was considered adequate. It is noteworthy that the latency time and the time of night sleep of the mother and the baby were obtained by the mother's subjective report. To correlate the data, Spearman's correlation was used in the statistical package R version 3.6.3. Results: 96 women and babies participated, aged 22 to 38 years (mean 30.8) and 10 to 24 months (mean 14.7), respectively. The average of maternal security was 2.89 (unsafe); Mean maternal state anxiety scores were 43.75 (moderate anxiety). The babies' average sleep latency time was 39.6 min (>20 min). The mean sleep times of the mother and baby were, respectively, 6h and 42min and 8h and 19min, both less than the recommended nocturnal sleep time. Maternal security was positively correlated with maternal state anxiety scores (rh=266, p=0.009) and negatively correlated with infant sleep latency (rh= -0.30. P=0.003). Baby sleep time was positively correlated with maternal sleep time. (rh 0.46, p<0.001). Conclusion: The more secure the mothers considered themselves, the higher the anxiety scores and the shorter the baby's sleep latency. Also, the longer the baby sleeps, the longer the mother sleeps.

These compounds act at the solid-liquid interface of colloidal suspensions of cement pastes, preventing agglomeration of the particles. Although the use in the concrete industry is wide, the mechanisms of dispersion of concrete admixtures composed of polycarboxylate in cement with supplementary cementitious materials have ample opportunity to be investigated, providing the attainment of increasingly compatible and efficient cement-addition-additive systems. The cements used in the research are Portland Cement CPV and two cements Portland Cement Composite (CPIV) with calcined clay contents of 20% and 28% and three commercial additives based on polycarboxylate. The performance of the additives and obtaining the optimal content was determined by the Marsh Cone test and spread by Mini-Slump. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcined%20clay" title="calcined clay">calcined clay</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20cements" title=" composite cements"> composite cements</a>, <a href="https://publications.waset.org/abstracts/search?q=superplasticizer%20additives" title=" superplasticizer additives"> superplasticizer additives</a>, <a href="https://publications.waset.org/abstracts/search?q=polycarboxylate" title=" polycarboxylate"> polycarboxylate</a> </p> <a href="https://publications.waset.org/abstracts/159324/determination-of-the-optimal-content-of-commercial-superplasticizer-additives-in-cements-with-calcined-clay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159324.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">106</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">98</span> Students’ Perceptions of Communication Design in Media: Case Study of Portuguese and Spanish Communication Students </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F%C3%A1tima%20Gon%C3%A7alves">Fátima Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Joaquim%20Brigas"> Joaquim Brigas</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Gon%C3%A7alves"> Jorge Gonçalves</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The proliferation of mobile devices in society enables the media to disseminate information and knowledge more rapidly.

The biological function of all proteins majorly relies on the shape of their three-dimensional conformational structure, but less than 1% of all known proteins in the world have their structure solved. This work proposes a deep learning model to address this problem, attempting to predict some aspects of the protein conformations. Throughout a process of multiobjective dominance, a recurrent neural network was trained to abstract the particular bias of each individual multiobjective algorithm, generating a heuristic that could be useful to predict some of the relevant aspects of the three-dimensional conformation process formation, known as protein folding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ab%20initio%20heuristic%20modeling" title="Ab initio heuristic modeling">Ab initio heuristic modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=multiobjective%20optimization" title=" multiobjective optimization"> multiobjective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20structure%20prediction" title=" protein structure prediction"> protein structure prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20neural%20network" title=" recurrent neural network"> recurrent neural network</a> </p> <a href="https://publications.waset.org/abstracts/141565/protein-tertiary-structure-prediction-by-a-multiobjective-optimization-and-neural-network-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141565.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">205</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">96</span> Modeling and Simulation of a Hybrid System Solar Panel and Wind Turbine in the Quingeo Heritage Center in Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Portoviejo%20Brito">Juan Portoviejo Brito</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Icaza%20Alvarez"> Daniel Icaza Alvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Castro%20Samaniego"> Christian Castro Samaniego</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we present the modeling, simulations, and energy conversion analysis of the solar-wind system for the Quingeo Heritage Center in Ecuador.

An analysis of the Transformative Leadership Theory, the Technology Acceptance Model, and the Diffusion of Innovation Process provide the support for a solid understanding of this issue and address recommendations for future technology implementation projects in higher education institutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diffusion%20of%20innovation%20process" title="diffusion of innovation process">diffusion of innovation process</a>, <a href="https://publications.waset.org/abstracts/search?q=instructional%20design" title=" instructional design"> instructional design</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20management%20systems" title=" learning management systems"> learning management systems</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20learning" title=" online learning"> online learning</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20acceptance%20model" title=" technology acceptance model"> technology acceptance model</a>, <a href="https://publications.waset.org/abstracts/search?q=transformative%20leadership%20theory" title=" transformative leadership theory"> transformative leadership theory</a> </p> <a href="https://publications.waset.org/abstracts/61023/transformative-leadership-and-learning-management-systems-implementation-leadership-practices-in-instructional-design-for-online-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61023.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">329</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">94</span> An Attempt to Improve Student´s Understanding on Thermal Conductivity Using Thermal Cameras</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Faria%20Brito%20Francisquini">Mariana Faria Brito Francisquini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many thermal phenomena are present and play a substantial role in our daily lives. This presence makes the study of this area at both High School and University levels a very widely explored topic in the literature. However, a lot of important concepts to a meaningful understanding of the world are neglected at the expense of a traditional approach with senseless algebraic problems. In this work, we intend to show how the introduction of new technologies in the classroom, namely thermal cameras, can work in our favor to make a clearer understanding of many of these concepts, such as thermal conductivity. The use of thermal cameras in the classroom tends to diminish the everlasting abstractness in thermal phenomena as they enable us to visualize something that happens right before our eyes, yet we cannot see it. In our study, we will provide the same amount of heat to metallic cylindrical rods of the same length, but different materials in order to study the thermal conductivity of each one. In this sense, the thermal camera allows us to visualize the increase in temperature along each rod in real time enabling us to infer how heat is being transferred from one part of the rod to another. Therefore, we intend to show how this approach can contribute to the exposure of students to more enriching, intellectually prolific, scenarios than those provided by traditional approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teaching%20physics" title="teaching physics">teaching physics</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20cameras" title=" thermal cameras"> thermal cameras</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20physics" title=" thermal physics"> thermal physics</a> </p> <a href="https://publications.waset.org/abstracts/52305/an-attempt-to-improve-students-understanding-on-thermal-conductivity-using-thermal-cameras" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52305.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">282</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">93</span> Multidisciplinary Rehabilitation Algorithm after Mandibular Resection for Ameloblastoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joaquim%20de%20Almeida%20Dultra">Joaquim de Almeida Dultra</a>, <a href="https://publications.waset.org/abstracts/search?q=Daiana%20Cristina%20Pereira%20Santana"> Daiana Cristina Pereira Santana</a>, <a href="https://publications.waset.org/abstracts/search?q=F%C3%A1tima%20Karoline%20Alves%20Ara%C3%BAjo%20Dultra"> Fátima Karoline Alves Araújo Dultra</a>, <a href="https://publications.waset.org/abstracts/search?q=Liliane%20Akemi%20Kawano%20Shibasaki"> Liliane Akemi Kawano Shibasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Machado%20Mendes%20de%20Carvalho"> Mariana Machado Mendes de Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Ieda%20Margarida%20Cruso%C3%A9%20Rocha%20Rebello"> Ieda Margarida Crusoé Rocha Rebello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Defects originating from mandibular resections can cause significant functional impairment and facial disharmony, and they have complex rehabilitation. The aim of this report is to demonstrate the authors' experience facing challenging rehabilitation after mandibular resection in a patient with ameloblastoma. Clinical and surgical steps are described simultaneously, highlighting the adaptation of the final fixed prosthesis, reported in an unprecedented way in the literature. A 37-year-old male patient was seen after a sports accident, where a pathological fracture in the symphysis and left mandibular body was identified, where a large radiolucent lesion was found. The patient underwent resection, bone graft, distraction osteogenesis, rehabilitation with dental implants, prosthesis, and finally, orofacial harmonization, in an interval of six years. Rehabilitation should consider the patient's needs individually and should have as the main objective to provide similar aesthetics and function to that present before the disease. We also emphasize the importance of interdisciplinary work during the course of rehabilitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ameloblastoma" title="ameloblastoma">ameloblastoma</a>, <a href="https://publications.waset.org/abstracts/search?q=mandibular%20reconstruction" title=" mandibular reconstruction"> mandibular reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=distraction%20osteogenesis" title=" distraction osteogenesis"> distraction osteogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20implants.%20dental%20prosthesis" title=" dental implants. dental prosthesis"> dental implants. dental prosthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=implant-supported" title=" implant-supported"> implant-supported</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20outcome" title=" treatment outcome"> treatment outcome</a> </p> <a href="https://publications.waset.org/abstracts/152841/multidisciplinary-rehabilitation-algorithm-after-mandibular-resection-for-ameloblastoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152841.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">111</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">92</span> Low Cost Surface Electromyographic Signal Amplifier Based on Arduino Microcontroller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igor%20Luiz%20Bernardes%20de%20Moura">Igor Luiz Bernardes de Moura</a>, <a href="https://publications.waset.org/abstracts/search?q=Luan%20Carlos%20de%20Sena%20Monteiro%20Ozelim"> Luan Carlos de Sena Monteiro Ozelim</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiano%20Araujo%20Soares"> Fabiano Araujo Soares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of a low cost acquisition system of S-EMG signals which are reliable, comfortable for the user and with high mobility shows to be a relevant proposition in modern biomedical engineering scenario. In the study, the sampling capacity of the Arduino microcontroller Atmel Atmega328 with an A/D converter with 10-bit resolution and its reconstructing capability of a signal of surface electromyography are analyzed. An electronic circuit to capture the signal through two differential channels was designed, signals from Biceps Brachialis of a healthy man of 21 years was acquired to test the system prototype. ARV, MDF, MNF and RMS estimators were used to compare de acquired signals with physiological values. The Arduino was configured with a sampling frequency of 1.5 kHz for each channel, and the tests with the circuit designed offered a SNR of 20.57dB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromyography" title="electromyography">electromyography</a>, <a href="https://publications.waset.org/abstracts/search?q=Arduino" title=" Arduino"> Arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost" title=" low-cost"> low-cost</a>, <a href="https://publications.waset.org/abstracts/search?q=atmel%20atmega328%20microcontroller" title=" atmel atmega328 microcontroller"> atmel atmega328 microcontroller</a> </p> <a href="https://publications.waset.org/abstracts/5919/low-cost-surface-electromyographic-signal-amplifier-based-on-arduino-microcontroller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5919.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">366</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">91</span> Models Development of Graphical Human Interface Using Fuzzy Logic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%89rick%20Arag%C3%A3o%20Ribeiro">Érick Aragão Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Andr%C3%A9%20Pereira%20Th%C3%A9"> George André Pereira Thé</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Marques%20Soares"> José Marques Soares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Graphical Human Interface, also known as supervision software, are increasingly present in industrial processes supported by Supervisory Control and Data Acquisition (SCADA) systems and so it is evident the need for qualified developers. In order to make engineering students able to produce high quality supervision software, method for the development must be created. In this paper we propose model, based on the international standards ISO/IEC 25010 and ISO/IEC 25040, for the development of graphical human interface. When compared with to other methods through experiments, the model here presented leads to improved quality indexes, therefore help guiding the decisions of programmers. Results show the efficiency of the models and the contribution to student learning. Students assessed the training they have received and considered it satisfactory. <p class="card-text"><strong>Keywords:</strong> <a
