defines the access to information as a crucial right of the citizen and the Law on Access to Public Information, which regulates this right. Accordingly, the Fiscal Responsibility Act, 2000, amended in 2009 by the “Law of Transparency”, began demanding a wider disclosure of public accounts for the society, including electronic media for public access. Thus, public entities began to create "Transparency Portals," which aim to gather a diversity of data and information. However, this information, in general, is still published in formats that do not simplify understanding of the data by citizens and that could be better especially available for audit purposes. In this context, a proposal of ontology about Brazilian Transparency Portal can play a key role in how these data will be better available. This study aims to identify and implement in ontology, the data model about Transparency Portal ecosystem, with emphasis in activities that use these data for some applications, like audits, press activities, social government control, and others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audit" title="audit">audit</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20transparency" title=" government transparency"> government transparency</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sector" title=" public sector"> public sector</a> </p> <a href="https://publications.waset.org/abstracts/14657/a-proposal-of-ontology-about-brazilian-government-transparency-portal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14657.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">506</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">6</span> Quality of Life of Health Professionals during the COVID-19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elucir%20Gir">Elucir Gir</a>, <a href="https://publications.waset.org/abstracts/search?q=Myllena%20Nilce%20de%20Freitas%20Surmano"> Myllena Nilce de Freitas Surmano</a>, <a href="https://publications.waset.org/abstracts/search?q=Laelson%20Rochelle%20Milan%C3%AAs%20Sousa"> Laelson Rochelle Milanês Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayra%20Gon%C3%A7alves%20Menegueti"> Mayra Gonçalves Menegueti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Cristina%20de%20Oliveira%20E%20Silva"> Ana Cristina de Oliveira E Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Renata%20Karina%20Reis"> Renata Karina Reis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To analyze the factors associated with the worsening of the quality of life of health professionals in the Southeast region of Brazil during the COVID-19 pandemic and its associated factors. Method: Analytical cross-sectional study carried out with health professionals from the southeastern region of Brazil. Data collection took place through an online survey with a form stored on the Survey Monkey platform. Bivariate analysis was used, and the chi-square test was adopted, followed by the multiple binary logistic regression model based on the stepwise method. Results: 3,493 health professionals participated in the study. Factors associated with worsening quality of life were: Professional Category (Nursing assistant) [OR 1.851 (95%CI 1.035-3.311) p= 0.038]; types of people who provided care (people in general) [OR 1.445 (95%CI 1.072-1.945) p=0.015]; Supply of good quality PPE by the institution where he works (no) [OR 1.595 (CI 95% 1.144-2.223) p= 0.006] and Supply of good quality PPE by the institution where he works (in part) [OR 1.563 (CI 95% 1.257-1.943) p < 0.001]. Conclusion: The factors associated with the worsening of the quality of life of health professionals during the COVID-19 pandemic were: Professional Category (Nursing assistant); types of people who provided assistance (people in general); Supply of sufficient PPE by the institution where you work (no) and Supply of good quality PPE by the institution where you work (in part). Future studies should investigate to what extent QoL can be improved based on modifiable factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20professionals" title=" health professionals"> health professionals</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20infections" title=" respiratory infections"> respiratory infections</a> </p> <a href="https://publications.waset.org/abstracts/165013/quality-of-life-of-health-professionals-during-the-covid-19-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165013.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">91</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">5</span> Factors Associated with Skin Injuries Due to the Use of N95 Masks among Brazilian Nursing Professionals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elucir%20Gir">Elucir Gir</a>, <a href="https://publications.waset.org/abstracts/search?q=Laelson%20Rochelle%20Milan%C3%AAs%20Sousa"> Laelson Rochelle Milanês Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Renata%20Karina%20Reis"> Renata Karina Reis</a>, <a href="https://publications.waset.org/abstracts/search?q=Soraia%20Assad%20Nasbine%20Rabeh"> Soraia Assad Nasbine Rabeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayra%20Gon%C3%A7alves%20Menegueti"> Mayra Gonçalves Menegueti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Cristina%20de%20Oliveira%20e%20Silva"> Ana Cristina de Oliveira e Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheila%20Ara%C3%BAjo%20Teles"> Sheila Araújo Teles</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Context and significance: Nursing team professionals faced challenges in combating the COVID-19 pandemic around the world. They were subjected to exhausting workloads and prolonged use of Personal Protective Equipment. Using N95 masks for long periods of time can cause skin changes. In this context, health professionals who worked on the front lines of fighting the pandemic were more exposed to possible physical and psychological changes. Objective: The aim of the study was to analyze the factors associated with skin lesions resulting from the use of N95 masks among nursing team professionals. Method: The study was carried out in all regions of Brazil from October to December 2020, with professionals from the nursing team who worked in health care during the COVID-19 pandemic. Participants were recruited via social media, and information was collected electronically and stored on the Survey Monkey platform. Descriptive statistics were used to characterize the sample, association tests (Chi-square), with a statistical significance level of p < 0.05. Factors associated with skin lesions resulting from the use of an N95 mask were determined by Binary Logistic Regression, with a significance level of 5% (α = 0.05). Results: 8,405 nursing professionals participated in the study, 5,492 nurses (65.3%), 2,747 nursing technicians (32.7%), and 7,084 females (84.3%). Female nursing team professionals were 1.4 times more likely to develop skin lesions due to the use of N95 masks when compared to males (OR 1.4 [CI95% 1.22 – 1.59] p < 0.001). The following protective factors were identified: nursing technician (ORA 0.608 [CI95% 0.43 – 0.86] p = 0.005) and not having provided assistance in field hospitals for COVID-19 (0.73 [CI95% 0.65-0.81] p<0.000). Conclusion: It was concluded that female nursing team professionals were more likely to have skin changes related to the use of N95 masks. The need for intervention studies is emphasized in order to explore measures to prevent these types of injuries.

To improve its properties, fortification of chocolate with polyphenols, anthocyanins, soy milk powder and other compounds has been evaluated in several studies. However, to our best knowledge, the addition of carotenes to chocolate has not been tested. Carotenoids, especially ß-carotene and lutein, are widely distributed in fruits and vegetables so that they could be extracted from agro-industrial waste, such as fruit processing. On the other hand, limonene produces crystalline changes of cocoa butter and improves its consistency and viscosity. This study aimed to evaluate the production of dark chocolate with the addition of carotenes extracted from an agro industrial waste and to improve its rheological properties and crystallization, with orange essential oil. The dried and fermented cocoa beans were purchased in Puerto Quito, Ecuador, and had a fat content of 51%. Six types of chocolates were formulated, and two formulations were chosen, one at 65% cocoa and other at 70% cocoa, both with a solid: fat ratio of 1.4:1. With the formulations selected, the influence of the addition of 0.75% and 1.5% orange essential oil was evaluated, and analysis to measure the viscosity, crystallization and sensory analysis were done. It was found that essential oil does not generate significant changes in the properties of chocolate, but has an important effect on aroma and coloration, which changed from auburn to brown. The best scores on sensory analysis were obtained for the samples formulated with 0.75% essential oil. Prior to the formulation with carotenes, the extraction of these compounds from pineapple peels were performed. The process was done with and without a previous enzymatic treatment, with three solid-solvent ratios. The best treatment was using enzymes in a solids-solvent ratio of 1:12.5; the extract obtained under these conditions had 4.503 ± 0.214 μg Eq. β-carotene/mL. This extract was encapsulated with gum arabic and maltodextrin, and the solution was dried using a freeze dryer. The encapsulated carotenes were added to the chocolate in an amount of 1.7% however 60,8 % of them were lost in the final product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cocoa" title="cocoa">cocoa</a>, <a href="https://publications.waset.org/abstracts/search?q=fat%20crystallization" title=" fat crystallization"> fat crystallization</a>, <a href="https://publications.waset.org/abstracts/search?q=limonene" title=" limonene"> limonene</a>, <a href="https://publications.waset.org/abstracts/search?q=carotenoids" title=" carotenoids"> carotenoids</a>, <a href="https://publications.waset.org/abstracts/search?q=pineapple%20peels" title=" pineapple peels"> pineapple peels</a> </p> <a href="https://publications.waset.org/abstracts/85362/rheological-and-crystallization-properties-of-dark-chocolate-formulated-with-essential-oil-of-orange-and-carotene-extracted-from-pineapple-peels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85362.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">3</span> Sediment Transport Monitoring in the Port of Veracruz Expansion Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Lia%C3%B1o-Carrera">Francisco Liaño-Carrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Isaac%20Ram%C3%ADrez-Mac%C3%ADas"> José Isaac Ramírez-Macías</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Salas-Monreal"> David Salas-Monreal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayra%20Lorena%20Riveron-Enzastiga"> Mayra Lorena Riveron-Enzastiga</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcos%20Rangel-Avalos"> Marcos Rangel-Avalos</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Andrea%20Rold%C3%A1n-Ubando"> Adriana Andrea Roldán-Ubando</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction of most coastal infrastructure developments around the world are usually made considering wave height, current velocities and river discharges; however, little effort has been paid to surveying sediment transport during dredging or the modification to currents outside the ports or marinas during and after the construction. This study shows a complete survey during the construction of one of the largest ports of the Gulf of Mexico. An anchored Acoustic Doppler Current Velocity profiler (ADCP), a towed ADCP and a combination of model outputs were used at the Veracruz port construction in order to describe the hourly sediment transport and current modifications in and out of the new port. Owing to the stability of the system the new port was construction inside Vergara Bay, a low wave energy system with a tidal range of up to 0.40 m. The results show a two-current system pattern within the bay. The north side of the bay has an anticyclonic gyre, while the southern part of the bay shows a cyclonic gyre. Sediment transport trajectories were made every hour using the anchored ADCP, a numerical model and the weekly data obtained from the towed ADCP within the entire bay. The sediment transport trajectories were carefully tracked since the bay is surrounded by coral reef structures which are sensitive to sedimentation rate and water turbidity. The survey shows that during dredging and rock input used to build the wave breaker sediments were locally added (< 2500 m<sup>2</sup>) and local currents disperse it in less than 4 h. While the river input located in the middle of the bay and the sewer system plant may add more than 10 times this amount during a rainy day or during the tourist season. Finally, the coastal line obtained seasonally with a drone suggests that the southern part of the bay has not been modified by the construction of the new port located in the northern part of the bay, owing to the two subsystem division of the bay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Acoustic%20Doppler%20Current%20Profiler" title="Acoustic Doppler Current Profiler">Acoustic Doppler Current Profiler</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20around%20coral%20reefs" title="construction around coral reefs">construction around coral reefs</a>, <a href="https://publications.waset.org/abstracts/search?q=dredging" title=" dredging"> dredging</a>, <a href="https://publications.waset.org/abstracts/search?q=port%20construction" title=" port construction"> port construction</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20transport%20monitoring" title=" sediment transport monitoring"> sediment transport monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/56628/sediment-transport-monitoring-in-the-port-of-veracruz-expansion-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56628.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">227</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">2</span> Topographic Coast Monitoring Using UAV Photogrammetry: A Case Study in Port of Veracruz Expansion Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Lia%C3%B1o-Carrera">Francisco Liaño-Carrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Enrique%20Ba%C3%B1os-Illana"> Jorge Enrique Baños-Illana</a>, <a href="https://publications.waset.org/abstracts/search?q=Arturo%20G%C3%B3mez-Barrero"> Arturo Gómez-Barrero</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Isaac%20Ram%C3%ADrez-Mac%C3%ADas"> José Isaac Ramírez-Macías</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Omar%20Paredes-Ju%C3%A1Rez"> Erik Omar Paredes-JuáRez</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Salas-Monreal"> David Salas-Monreal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayra%20Lorena%20Riveron-Enzastiga"> Mayra Lorena Riveron-Enzastiga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Topographical changes in coastal areas are usually assessed with airborne LIDAR and conventional photogrammetry. In recent times Unmanned Aerial Vehicles (UAV) have been used several in photogrammetric applications including coastline evolution. However, its use goes further by using the points cloud associated to generate beach Digital Elevation Models (DEM). We present a methodology for monitoring coastal topographic changes along a 50 km coastline in Veracruz, Mexico using high-resolution images (less than 10 cm ground resolution) and dense points cloud captured with an UAV. This monitoring develops in the context of the port of Veracruz expansion project which construction began in 2015 and intends to characterize coast evolution and prevent and mitigate project impacts on coastal environments. The monitoring began with a historical coastline reconstruction since 1979 to 2015 using aerial photography and Landsat imagery. We could define some patterns: the northern part of the study area showed accretion while the southern part of the study area showed erosion. Since the study area is located off the port of Veracruz, a touristic and economical Mexican urban city, where coastal development structures have been built since 1979 in a continuous way, the local beaches of the touristic area are been refilled constantly. Those areas were not described as accretion since every month sand-filled trucks refill the sand beaches located in front of the hotel area. The construction of marinas and the comitial port of Veracruz, the old and the new expansion were made in the erosion part of the area. Northward from the City of Veracruz the beaches were described as accretion areas while southward from the city, the beaches were described as erosion areas. One of the problems is the expansion of the new development in the southern area of the city using the beach view as an incentive to buy front beach houses. We assessed coastal changes between seasons using high-resolution images and also points clouds during 2016 and preliminary results confirm that UAVs can be used in permanent coast monitoring programs with excellent performance and detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20elevation%20model" title="digital elevation model">digital elevation model</a>, <a href="https://publications.waset.org/abstracts/search?q=high-resolution%20images" title=" high-resolution images"> high-resolution images</a>, <a href="https://publications.waset.org/abstracts/search?q=topographic%20coast%20monitoring" title=" topographic coast monitoring"> topographic coast monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicle" title=" unmanned aerial vehicle"> unmanned aerial vehicle</a> </p> <a href="https://publications.waset.org/abstracts/56681/topographic-coast-monitoring-using-uav-photogrammetry-a-case-study-in-port-of-veracruz-expansion-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56681.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">270</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">1</span> Phage Display-Derived Vaccine Candidates for Control of Bovine Anaplasmosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Itzel%20Amaro-Estrada">Itzel Amaro-Estrada</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Vergara-Rivera"> Eduardo Vergara-Rivera</a>, <a href="https://publications.waset.org/abstracts/search?q=Virginia%20Juarez-Flores"> Virginia Juarez-Flores</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayra%20Cobaxin-Cardenas"> Mayra Cobaxin-Cardenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosa%20Estela%20Quiroz"> Rosa Estela Quiroz</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesus%20F.%20Preciado"> Jesus F.

Sick bovine can recover when antibiotics are administered; however, it usually remains as carrier for life, being a risk of infection for susceptible cattle. Anaplasma marginale is an obligate intracellular Gram-negative bacterium with genetic composition highly diverse among geographical isolates. There are currently no vaccines fully effective against bovine anaplasmosis; therefore, the economic losses due to disease are present. Vaccine formulation became a hard task for several pathogens as Anaplasma marginale, but peptide-based vaccines are an interesting proposal way to induce specific responses. Phage-displayed peptide libraries have been proved one of the most powerful technologies for identifying specific ligands. Screening of these peptides libraries is also a tool for studying interactions between proteins or peptides. Thus, it has allowed the identification of ligands recognized by polyclonal antiserums, and it has been successful for the identification of relevant epitopes in chronic diseases and toxicological conditions. Protective immune response to bovine anaplasmosis includes high levels of immunoglobulins subclass G2 (IgG2) but not subclass IgG1. Therefore, IgG2 from the serum of protected bovine can be useful to identify ligands, which can be part of an immunogen for cattle. In this work, phage display random peptide library Ph.D. ™ -12 was incubating with IgG2 or blood sera of immunized bovines against A. marginale as targets. After three rounds of biopanning, several candidates were selected for additional analysis. Subsequently, their reactivity with sera immunized against A. marginale, as well as with positive and negative sera to A. marginale was evaluated by immunoassays. A collection of recognized peptides tested by ELISA was generated. More than three hundred phage-peptides were separately evaluated against molecules which were used during panning. At least ten different peptides sequences were determined from their nucleotide composition. In this approach, three phage-peptides were selected by their binding and affinity properties. In the case of the development of vaccines or diagnostic reagents, it is important to evaluate the immunogenic and antigenic properties of the peptides. Immunogenic in vitro and in vivo behavior of peptides will be assayed as synthetic and as phage-peptide for to determinate their vaccine potential.
