http://ijaers.com/ Open Access international Journal to publish research paper en-us April We aim to identify aspects of public transparency in the literature and its influence on the efficiency of public management. For this purpose, a bibliometric study of works published in scientific journals available in the Scopus database was carried out. Initially, 74 academic works were identified using the keywords "transparency", "public governance" and "efficient institutions" after this first filtering, it was restricted only to scientific articles aligned with the theme, generating the final base of 27 articles that were analyzed. quantitatively and qualitatively using the frequency count of the data, finally a word cloud and similarity analysis was carried out with the support of the Iramuteq textual analysis software. Among the main contributions of this article, the understanding of how the works of different origins, years and authors came together in an academic collection that allows us to understand how the authors see public governance and transparency in the construction of efficient institutions. http://ijaers.com/detail/transparency-as-a-tool-in-building-efficient-public-institutions-a-bibliometric-study/ Josué de Lima Carvalho, Tânia Suely Azevedo Brasileiro http://ijaers.com/uploads/issue_files/1IJAERS-03202220-Transparency.pdf The stabilization pond system this which is efficient in removing organic pollutants but can present operational problems such as sediment accumulation due to lack of maintenance or operational errors, negatively influencing the efficiency of the treatment. Based on these considerations, this work evaluated the hydrodynamic behavior of an facultative pond. The hydrodynamic evaluation was carried out through the computational dynamics of the fluids, from which the main operational problems and areas of occurrence were identified. Five main regions were verified in the pond bed, with the effects of recirculation, dead zone, and short circuit zone occurring in these places. It was concluded with this study that the irregular accumulation of sediments in the pond beder and the irregular shape of the pond geometry, which contributes to the fluid is associated with the velocity of entry of the wastewater not flowing in an orderly way throughout the bed. http://ijaers.com/detail/modeling-the-hydrodynamic-behavior-of-facultative-pond-using-computational-fluidodynamic-tool-2/ Leandro Conti Garcia, Flávia Aparecida Reitz Cardoso, Flávia Vieira da Silva Medeiros, Thiago Morais de Castro, Eudes José Arantes http://ijaers.com/uploads/issue_files/2IJAERS-03202243-Modeling.pdf Treatment of structurally compromised endodontically treated teeth (ETT) is still a controversial topic faced daily in clinical practice. A correct diagnosis and treatment planning is mandatory to accomplish success and survival of the restoration, but most importantly, to stop the cycle of death of the tooth. This 1-year follow-up case report presents a no post/no crown fiber-reinforced restoration of a structurally compromised endodontically treated tooth. A 65-year-old female sought treatment for her upper left first premolar that had had endodontic treatment and an old MOD amalgam filling from a long time ago before it broke down. The buccal cusp was fractured, leaving less than 50% of the coronal tooth structure. While a conventional approach would require a cast metal or fiber post and a full-coverage crown, a biomimetic approach was chosen for this case. Therefore, a biobase was used for dentin replacement, and a ceramic restoration replaced the enamel. The biobase was reinforced with polyethylene fiber at its base to reduce the stress generated in the hybrid layer. Reconstruction of the dentin core was carried out with a short fiber-reinforced composite resin, which has mechanical properties similar to dentin. The palatal cusp was maintained, and a vonlay preparation was made, covering the remaining cusp. For enamel replacement, a lithium disilicate ceramic was used. The follow-up of this clinical report presents success and survival for 1 year. http://ijaers.com/detail/modeling-the-hydrodynamic-behavior-of-facultative-pond-using-computational-fluidodynamic-tool/ José Antonio Castro Klenner, Priscilla Cardoso Lazari-Carvalho, Tomás Felipe Labarca Galecio, Marco Aurélio de Carvalho http://ijaers.com/uploads/issue_files/3IJAERS-03202245-A1-year.pdf In the current industry the search for process optimization has been more and more constant, however many times this practice proves to be quite complex given the number of variables involved, an example of this is the case where from a heterogeneous group of workers want to define the best set of work pairs so that the collective productivity is as high as possible. In situations like this, the use of the metaheuristic genetic algorithm becomes quite attractive, since in the literature there are many examples of its use in the optimization of non-linear problems, with continuous and discrete characteristics of the control variables and with an exponential increase in the number possible solutions, in addition to the flexibility to incorporate the real problem constraints into the solution. In this context, this study codified a problem of real case for the definition of work teams in a mining wagon maintenance workshop. In the theoretical simulation stage, using historical team performance data, the genetic algorithm indicated a 22 percent better solution when compared to the random choice of work teams. Finally, the solution suggested by the genetic algorithm was implemented in the field, resulting in a performance increase of 7.9percent. http://ijaers.com/detail/productivity-optimization-by-optimal-allocation-of-human-resources-with-application-in-real-case-at-the-wagons-maintenance-of-iron-ore-rail-transport/ Clóvis Bôsco Mendonça Oliveira, Jonas Fontes de Carvalho, Antônio José Silva Oliveira http://ijaers.com/uploads/issue_files/4IJAERS-03202248-Productivity.pdf In this work, an online and real-time monitoring system was developed in order to perform Condition-Based Maintenance (CBM). The proposed system named HC 4.0 uses low-cost hardware components such as an Arduino microcontroller and the graphical user interface was designed with the Grafana software, an open-source platform, to measure temperature, relative humidity, compressors currents and motor fan currents in a central air conditioning unit installed at a Brazilian Clinical Hospital named “Hospital das Clínicas da UFG/EBSERH” (HC-UFG/EBSERH). The HC 4.0 solution presents as a result useful information for the maintenance team indicating how to act in a faster, more assertive and effective way regarding the inherent failure modes that are dealt with in a usual work routine. A long-time experiment was conducted for 30 days while the Hospital was operating normally and prominent results were obtained. A designed dashboard through Grafana is used to evaluate the conditions required in order to make an early intervention in the equipment. Furthermore, the system is able to send alerts to the maintainer’s cellphones by using a message app such as Telegram, when some parameter goes beyond the pre-defined limits. Additionally, a Failure Mode and Effect Analysis (FMEA) for the central air conditioning unit of the hospital is presented alongside the recommendations to each situation for the maintainer. The results encourage the use and further development of the HC 4.0 approach in order to implement low-cost CBM of Hospital equipment’s such as the central air conditioning unit focused on this work. http://ijaers.com/detail/implementation-of-condition-based-maintenance-cbm-in-a-central-air-conditioning-unit-by-using-microcontroller-and-open-source-monitoring-platforms/ Danilo Augusto Santana de Souza, Matheus Damaceno Artur, Diogo de Souza Rabelo, Fernando Nunes Belchior http://ijaers.com/uploads/issue_files/5IJAERS-03202250-Implementation.pdf Some of the main agro-industrial residues available in the cerrado region in the south of the state of Tocantins were evaluated for the cultivation of the Pleurotus ostreatus mushroom. The following substrates, hay and andropogon grass, enriched with barley, organic compost, and corn cob, were tested. All substrates received 2% inoculant (Cal) and were incubated at 24°C. After colonization, the spawn were kept in an air-conditioned environment for 24 hours and humidity at 80%. The substrate andropogon grass increased with corn cob added with 2% lime showed the best result in mushroom production, with a biological efficiency of 39.08% and an average production of 381.07 g/Kg substrate in 25 days of follow-up. http://ijaers.com/detail/pleurotus-ostreatus-mushroom-productivity-in-different-substrates-of-agro-industrial-residues-generated-in-the-southern-region-of-tocantins-brazil/ Ana Luiza Santiago Pereira, Aloisio Freitas Chagas Junior, Marcos Giongo, Gessiel Newton Scheidt, Jader Nunes Cachoeira, Augustus Caeser Franke Portella http://ijaers.com/uploads/issue_files/6IJAERS-0420223-Pleurotus.pdf The production of specialty coffees is an important activity for farm incomes and should be encouraged. However, it is necessary that this process may respect the principles based on the economic, environmental, and social axes of sustainability. This research was carried out aiming to generate the initial benchmark of the sustainability of four farms in the municipality of Afonso Cláudio, State of Espírito Santo, Brazil. The System for Assessing Sustainability Standards for Coffee Growing in Espírito Santo, a tool in the format of an electronic spreadsheet, was used in order to quantify the scores of the different standards. The results showed a gap in the three axes with intervention needs mainly related to economical standards, followed by environmental, and social ones. The main interferences have been related to the quality of coffee beans management, costs and incomes of the farms, improvement in harvest and post-harvest processes, training in the use of manual machines, and the correct use of pesticides. Different intervention techniques will be offered to coffee-growers for intervention in the farms aiming to improve the level of their adequacy regarding the sustainability standards. However, the owner's family values, as well as their cultural and economic restrictions, must be respected. Thus, the results of farm adjustments must be achieved in different ways and at different times. http://ijaers.com/detail/establishing-the-initial-benchmark-for-the-sustainability-of-arabica-coffee-growing-householders-in-a-highland-region-brazil/ David Brunelli Viçosi, Cecília Uliana Zandonadi, Victor dos Santos Rossi, Wesley Zambom da Silva, Fabiano Tristão Alixandre, Cesar Abel Krohling, Cleber Cássio Ferreira, Evaldo de Paula, Marx Bussular Martinuzzo, Douglas Gonzaga de Souza, Maurício Lorenção Fornazier, Lúcio Herzog De Muner, Ricardo Dias Alixandre, Higor Alixandre Macette, David dos Santos Martins, Luiz Fernando Favarato, Maurício José Fornazier, Rogério Carvalho Guarçoni http://ijaers.com/uploads/issue_files/7IJAERS-03202246-Establishing.pdf Objective:To evaluate the relationship between clinical aspects and neurodevelopment in premature children with mild PIVH aged 6 to 24 months. The data were compared with that of children without PIVH. The parents' perception and adherence to the physiotherapy treatment was evaluated. Methods: Clinical aspects were related to data in the Denver II Test of premature children with mild PIVH and without PIVH, with statistical tests and p 7 days, and physiotherapy. Conclusion: Premature children with mild PIVH had a worse neuropsychomotor outcome when compared to children without PIVH. Developmental delay was associated with the presence of PIVH and the use of mechanical ventilation. The parents’ perception of neuropsychomotor delay was low and was associated to the low adherence to treatment. http://ijaers.com/detail/mild-peri-intraventricular-hemorrhage-pivh-factors-associated-with-neurodevelopment-and-the-parents-perception/ Luara Fernandes Argenton Duarte, Gloria M.

Data collection in this study used tests and questionnaires, the test consisted of the van Hiele test consist of 25 multiple choice questions and 2 geometric questions designed based on indicators of creative thinking, namely fluency, flexibility, originally, and ellaborasy. 1) Students at the visualization level in solving geometry problems are students who are able to meet the fluency indicators, while for the indicators of flexibility, authenticity, and details students cannot fulfill them because the answer sheets are still not visible. In addition, at the time of the interview, the students were also unable to give. 2) Students at the analytical level in solving geometry problems are students able to meet all indicators of creative thinking, namely fluency, flexibility, originality and detail. 3) Informal deduction level students in solving geometry problems are students able to meet the indicators of fluency, flexibility and detail, while the informal deduction level students' authenticity indicators have not been able to fulfill them. http://ijaers.com/detail/profile-of-creative-thinking-ability-in-junior-high-school-in-solving-flat-building-geometry-problems-in-term-of-van-hiele-s-level-and-students-visual-learning-styles/ P Maharani, Susanto, N Yuliati, M A Kusuma http://ijaers.com/uploads/issue_files/9IJAERS-0420227-Profile.pdf The main operational problems found in facultative ponds are the dead zones, short circuit zones of recirculation zones, caused mainly by the accumulation of solids in the bed. The use of baffles is one way of mitigating these problems. Thus, the objective of this work is to compare four baffle installation formats in an optional pond using computational fluid dynamics, and subsequently to identify the occurrence of the main operational problems in each model. For the development of the study, the software Ansys 14.5®was used, where the geometry of the analyzed pond was replicated, including in each model a different layout of the baffles. The use of deflectors allowed the mitigation of the main problems, such as the accumulation of sediments, and it was able to increase the flow velocity in all scenarios, as well as bringing the hydraulic retention time closer to that of the project. According to the data obtained, and the visual analysis of the simulations, it is possible to affirm that the baffle layouts assessed in scenario four would be more adequate to mitigate the operational problems found in the studied pond, as this arrangement conditions the flow of the piston type, which provides less sediment accumulation and the development of dead zones and short circuit zones in the bed. It was concluded that the installation of baffles could mitigate the operational problems of stabilization ponds by directing the flow. Likewise, there was a need for continuous studies to improve wastewater treatment systems. http://ijaers.com/detail/hydrodynamic-analysis-of-different-baffle-layouts-in-a-facultative-pond-to-mitigate-operational-problems-through-computational-fluidodynamics/ Leandro Conti Garcia, Flávia Aparecida Reitz Cardoso, Flávia Vieira da Silva Medeiros, Thiago Morais de Castro and Eudes José Arantes http://ijaers.com/uploads/issue_files/10IJAERS-0420226-Hydrodynamic.pdf Events not directly related to the operation of companies, such as elections and changes in laws, can influence the value of shares and impact the stock market as a whole. Considering the proximity of the Brazilian presidential election in 2022, and aiming to assess trends in the value of some shares and the Brazilian stock market, in this paper it is presented the analysis of the Accumulated Abnormal Returns on the value of common shares of large Brazilian companies after presidential elections. It is also presented the immediate reaction of the Brazilian Stock Market (B3). Eight companies were selected for the study, they are: Petrobras, Banco do Brasil, Vale, Itaúsa, Eletrobrás, Itaú Unibanco Holding and JBS. The criterion for this selection was based on the Forbes Global 2000 ranking published from 2008 to 2021, as will be detailed in the methodology. An Event Study was conducted to calculate the Accumulated Abnormal Returns (RAA) on the value of shares after the first round (event 1) and second round (event 2) of the presidential elections of 2002, 2006, 2010, 2014 and 2018. It was concluded that there were abnormal returns arising from the results of the presidential elections and some common shares were more impacted than others. In the joint view (first and second rounds of each election), Petrobras common shares were the only ones that presented a negative joint Accumulated Abnormal Return (RAAc) after all presidential elections, in addition to obtaining the highest negative RAAc. About the market reaction, captured through the analysis of the Ibovespa, it was observed that the result was negative in the first victory of Lula (2002), however, in his reelection (2006), it was obtained the highest positive result. Regarding the Bolsonaro election (2018), the Ibovespa ROAc was 6.6%, being the most optimistic compared to the first election of Lula (2002) and Dilma (2010). http://ijaers.com/detail/from-lula-to-bolsonaro-the-immediate-impacts-of-elections-on-abnormal-returns-in-b3-listed-companies/ Alysson Vasconcelos Gomes de Menezes, Maycon Peter da Rosa, Roberto Pires Soares Júnior, Nelson Hein, Adriana Kroenke Hein http://ijaers.com/uploads/issue_files/11IJAERS-04202214-From.pdf Syphilis is a Sexually Transmitted Infection caused by the bacterium Treponema pallidum, with various forms of clinical presentations and different stages. When not diagnosed and treated early, it can cause harm to the pregnant woman and fetus. The present study aimed to identify the characteristics of the epidemiological profile of pregnant women affected by syphilis in the city of Cacoal between 2016 and 2020. Descriptive, retrospective and quantitative documentary research, where the initial sample consisted of 95 pregnant women who were registered in the database SINAN data with a diagnosis of Gestational Syphilis. The collected data were distributed and presented by means of statistics through tables and/or graphs elaborated after the analysis. The study complies with CONEP Resolution No. 466/2012 and was developed after approval by the CEP under Opinion 5,060,962. As a result of the research, it was identified that the year with the highest notification rate was in 2020, totaling 26% of cases, the predominance of the diagnosis was stopped in the first gestational trimester with 53%, in relation to age there was a variation between 14 and 41 years. of age, with an average age of 23 years and greater involvement in the young population, from 21 to 30 years of age, comprising 45% of the sample, 33% have completed high school and only 2% have completed higher education. Regarding the clinical classification, 76% of the cases were diagnosed as tertiary syphilis, the rapid test was performed in 84% of the pregnant women and the VDRL in 94%, in both with a predominant reagent result rate, without the occurrence of concomitant non-performance of the tests, it was observed that the titration 8 of VDRL/RPR was predominant, totaling 18% of the cases studied. It is concluded that the increase in the number of cases, the predominance in the young population with complete secondary education, the diagnosis in the first trimester, however prevalently in the tertiary phase, and the failure to perform the rapid test in part of the cases, although the Ministry of Health recommends, highlight the need for improvements in the effectiveness of prenatal care and to outline strategies for prevention, promotion and health awareness. http://ijaers.com/detail/epidemiological-profile-of-gestational-syphilis-in-the-municipality-of-cacoal-between-2016-and-2020/ Gabriely Karyse Bonfim Gera, Vinicius Gabriel Dumer Bressa, Maria Samara da Silva Fernandes, Gleison Faria, Iuri Santana de Jesus, Francisco Leandro Soares de Souza, Gilvan Salvador Junior, Gesnaquele Souza da Cruz, Valérian Santos Souza Semczyszym, Taís Loutarte Oliveira, Karolayne Soares Cavalcanti, Gean Carlos da Silva Saar, Dhieniffer Naiara da Silva, Ana Karolina Monge Silva Romano Mendonça, Elida Will, Vanessa Cardoso da Silva, Gislaine da Silva Santos, Pedro Washington Moreira Antunes, Francielly Maira Bordon, Davit Matuchaki dos Santos, Amanda Carolina Mendes Araujo, Wellington Ferreira de Souza, Giselen Maleski Cargnin, Vanessa Botoni da Silva Nogueira, Marco Rogério da Silva http://ijaers.com/uploads/issue_files/12IJAERS-0420222-Epidemiological.pdf To review the literature on the association between cannabis use as a triggering factor for schizophrenia in individuals with a predisposition to psychosis who used cannabis and to verify the relationship with the pathogenesis. http://ijaers.com/detail/marijuana-use-and-the-risk-of-schizophrenia/ Jade Ferreira Geraldes Iglesias, Jhonas Geraldo Peixoto Flauzino, Ana Luísa Carreira da Silveira, Ana Paula Dupuy Hermes, Dilter José Picin Correa de Oliveira, Enzo Masgrau de Oliveira Sanchotene, Gabriela Póvoas Pinto Ambar, Gabriel Ramos Canato, Isadora Ribeiro Rossi, Marcela Curvêllo Beltrão, Monaí Barbosa Oliveira, Natalia Maria Schincariol, Pedro Pompeo Boechat Araujo http://ijaers.com/uploads/issue_files/13IJAERS-04202237-Marijuana.pdf The pandemic due to COVID-19 has been shaping the healthcare landscape, mainly due to the amount of Health Service Waste (RSS) that is being produced. Understanding how these SSR are managed and how health professionals are involved in this process can provide a better understanding of how this knowledge directly impacts the better management of the SSR itself, as well as the reduction of environmental impacts from this flow. The objective of the study is to evaluate the knowledge of health professionals on waste management in time of COVID-19. An exploratory, descriptive, cross-sectional, observational study was conducted with 55 health professionals, working in a public hospital in Manaus – Amazonas - Brazil. Were included subjects over 18 years old, working in an institution that dealt with confirmed cases of COVID-19. The instruments used in the data collection were: Questionnaire defining the profile of the participants; Questionnaire evaluating basic knowledge about waste management of health services. The results indicated that the institution of interest has a protocol for the management of residues contaminated by COVID-19 as reported by 50 participants (90.9%), but most do not know what the Health Services Waste Management Plan (56.4%) is, not received training on SRHS (69.1%), not knowing how to classify without difficulty which are the Health Service Residues (54.5%), even performing invasive procedures (87.3%).

This study aims to overcome the issue by developing a learning media with Project-based learning STEM on projectile motion. The media which accommodated the catapult project was developed for secondary schools on google sites. In this research, the media was developed by conducting the Research and Development (RnD) method with the ADDIE model, consisting of five steps: analyze, design, develop, implement, and evaluate. Furthermore, the media was validated by experts and then implemented to the students. Finally, the validation and implementation results were analyzed with four points of the Likert scale. The validation results showed that the average score of the material aspect was 3.8. Meanwhile, the media aspect was 3.3. After the revision, the media was implemented to the students. The average of implementation cores showed that the material aspect was 3.6, the media aspect was 3.6, and the benefit aspect was 3.5. Both validation and implementation results showed that the media was excellent. Therefore, the project-based learning STEM with a catapult project can be applied as a supplemented media for the projectile motion learning process and applied in online learning during the covid-19 pandemic. http://ijaers.com/detail/project-based-learning-stem-to-enhance-secondary-school-students-comprehension-on-projectile-motion/ Mutia Delina, B H Iswanto, S Ditania http://ijaers.com/uploads/issue_files/15IJAERS-0420228-Projectbased.pdf The intestinal microbiota influences important local and systemic processes for the organism, having in its composition probiotic bacteria that assist in the beneficial processes and common bacteria, which often cause infections.

Probiotic supplementation is able to provide benefits on both qualitative and quantitative mental health parameters in anxiety and mood. Even with the limitation of studies regarding the use of probiotics in improving anxiety and depression in humans, most studies have identified positive results, in healthy or unhealthy people. One of the most commonly used probiotics is the genus Bifidobacterium. It has been shown to be efficient in inflammatory disorders, and it has been suggested that this probiotic may have antidepressant properties, since the balance between anti- and pro-inflammatory cytokines plays a relevant role in depression. http://ijaers.com/detail/intestinal-microbiota-in-anxiety-and-depression/ Caroline Krabbe Erthal, Jhonas Geraldo Peixoto Flauzino, Alexia Allis Rocha Lima, Ana Paula Dupuy Hermes, Ana Luiza Alves Fonseca Pellissaro, Beatriz Ramos Canato, Catarina Castro dos Santos, Enzo Masgrau de Oliveira Sanchotene, Giovanna Biângulo Lacerda Chaves, Kamila Giovana Lacerda Villas Bôas Dechichi, Marcela Lara Albuquerque Ranulfo, Natalia Maria Schincariol, Pedro Pompeo Boechat Araujo, Susana Gfoni da Silveira, Victor Ryan Ferrão Chaves http://ijaers.com/uploads/issue_files/17IJAERS-04202244-Intestinal.pdf Guarana is a plant native to the state of Amazonas that found favorable soil and climate conditions for its development in southern Bahia. It is recognized worldwide for its medicinal and stimulant properties from the presence of alkaloids from the methylxanthine group, such as caffeine. The caffeine content in guarana can reach 6%, a content four times higher than arabica coffee, which makes it a useful raw material for the caffeine extraction process. Among the caffeine extraction processes, there is the method of extraction by chemical solvents, which, in addition to being expensive, are very harmful to the environment, so an alternative is the use of water as a solvent, which also has a good affinity in the process. extraction and does not harm the environment like chemical solvents. The objective of this project is to optimize the process of extracting caffeine from guarana seeds, using water as a solvent, through an experimental design. Chromatographic and microbiological analyzes will be carried out and the concentration of the extract will be performed with the highest yield by the spray drying method. Data evaluation will be performed using the Statistica software version 10, for analysis of variance with a 95% confidence interval.

This study aimed to evaluate the epidemiological outcomes in patients with SAH from 2006 to 2018 through a predictive equation, considering the following variables: risk factors, early manifestations, complementary needs, neurological and systemic complications. The subjects of this study were hospitalized patients with a proven diagnosis of SAH, evaluated by the Hunt-Hess and Fisher scales and classified by the modified Rankin scale (mRS). To reach this objective, binary logistic regression was applied, with risk factors as independent variables and epidemiological outcomes as dependent. A total of 148 patients were documented, 65% female and 35% male, with a mean age of 53.7 years. Heart disease was an important predictor for the severe disability outcome, the combination of sensory impairment and syncope explained cases of death by 75.7%. Among neurological complications, hydrocephalus and vasospasm explained the severe cases and ischemic injury and rebleeding explained the death. For systemic complications, hyperglycemia and aspiration pneumonia together represented predictors for severe cases and death events, which can be explained by the presence of sepsis and fever. There is a need to intensify health prevention programs for chronic diseases and women’s health, as well as implement hospital assessment protocols. http://ijaers.com/detail/predictive-models-of-epidemiological-outcomes-for-patients-with-subarachnoid-hemorrhage/ Jarbas Galvão, Daniela Delwing de Lima, Leandro José Haas, Eduardo Manoel Pereira http://ijaers.com/uploads/issue_files/20IJAERS-04202216-Predictivemodels.pdf The performance of small photovoltaic (PV) systems connected to the grid in the state of Ceará is analyzed in this study.

Services to meet the demand for electrical stability require improvement in determining transformer trouble points not proportional to the number of State Electricity Company officers available dealing with the measurement of the transformer peak load that keeps changing due to the large number of new customers or those adding electrical power load. The development of the constantly increased electrical power load cannot be monitored properly anymore, and there is not yet appropriate technology applied for monitoring it. Therefore a new device is required so as to function facilitating officers in the distribution transformer load monitoring across various places in real time 24 hours, and the data can also be retrieved in real time as desired. The output of this device is in the form of visual data. If the transformer is overloaded, it can be designed using a visual basic interface, and in the system there is a microcontroller able to provide information for the officers quickly, to reduce investment in purchasing new transformers. http://ijaers.com/detail/prototype-of-distribution-transformer-load-reliability-system-based-using-visual-basic-interface/ Firman Yudianto, Fajar Annas Susanto, Teguh Herlambang http://ijaers.com/uploads/issue_files/23IJAERS-04202231-Prototype.pdf This paper aims to analyze how the induction factors of the built environment from the revitalization works of Marquês do Paraná Avenue, in the central area of the municipality of Niteroi/RJ- Brazil. Moreover, their relations with the advances brought by the Sustainable Urban Mobility Plan (PMUS) released in 2019, which influenced the transformations of the mobility paradigm along the avenue and in its nearby neighborhoods, were also objects of evaluation. It was applied an analytical and exploratory methodology of the attributes executed in the Nova Marquês do Paraná Project, evaluating the improvements of mobility noticed on the street when compared to the urban planning of this avenue in the past. It was possible to contrast the current induction factors of the built environment to sustainable mobility with the mobility attributes historically prevalent in the avenue that characterized it as a street axis of passage, inviting only motorized traffic. It was observed that these induction factors acquired the potential to transform local dynamics of displacement and permanence, induced the choice of active modes of travel integrated to public transport and enhance social, economic and leisure activities at the adjacent public spaces of the avenue. This research concluded that the new induction factors are means that can incorporate the human scale on the avenue, promote integrated management of public transport and land use and become reference practices for future masterplans and urban projects in Niterói and similar cities. http://ijaers.com/detail/induction-factors-of-the-built-environment-to-sustainable-mobility-the-case-of-the-nova-marqu-s-do-paran-project-in-the-downtown-area-of-niter-i-rj-brazil/ Bernardo Granville de Paula Cople, Giovani Manso Ávila http://ijaers.com/uploads/issue_files/24IJAERS-04202235-InductionFactors.pdf This study aimed to obtain information needs (need assessment).

The results of the science process skills hypothesis test of students in the experimental class and the control class had a significance value of less than 0.05, so it can be concluded that the learning model based on science discovery technology that integrated religious values had a significant effect on students' science process skills. http://ijaers.com/detail/analysis-of-students-science-process-skills-by-developing-a-science-technology-society-sts-model-that-integrated-religious-values-at-al-hasan-senior-high-school-jember/ Widiet Nurcahyo Ramadhana, Suratno, and Yushardi http://ijaers.com/uploads/issue_files/25IJAERS-0420229-Analysisof.pdf Coffee production has a great socioeconomic importance for Brazil. It generates direct and indirect jobs, and foreign exchange, with Brazilian Arabica coffee production estimated between 42 - 46 million bags (60 kg) in 2020. It is the main agribusiness activity in the State of Espírito Santo, Brazil with expected production between 13 - 15 million bags, and around 30% of this production is Arabica coffee. Technologies are recommended to coffee growers to increase yield, and production of specialty coffees on sustainable properties. Among the principles of integrated management is the monitoring of pests and diseases to determine the level of pest control. The estimate of the number of leaves to be sampled in the monitoring becomes an important tool to increase the accuracy of the obtained information. This research was carried out aiming to determine the minimum number of leaves necessary to evaluate the infestation of brown eye spot (BES) of coffee in Arabica coffee (Coffea arabica L.) without affecting the accuracy of the collection method. It was observed that the estimate of the minimum number for sampling was 46 leaves for the characteristics of incidence, and severity of BES in Arabica coffee. The modeling applied in this study allows to conclude that it is possible to recommend an optimum number of Arabica coffee leaves for these edaphoclimatic conditions, and variety, and it can serve as a basis for monitoring in an integrated pest and disease management program in Arabica coffee. http://ijaers.com/detail/modeling-the-brown-eye-spot-sampling-in-arabica-coffee/ José Salazar Zanuncio Junior, Hélcio Costa, Raíza Rainha Dorzenoni, Rogério Carvalho Guarçoni, Maurício Lorenção Fornazier, Suiane Reinaldo Sossai, Luciana Aparecida Botacim, Elaine Manelli Riva Souza, Maria Amélia Gava Ferrão, David dos Santos Martins, Luiz Fernando Favarato, Maurício José Fornazier http://ijaers.com/uploads/issue_files/26IJAERS-04202224-Modelingthe.pdf Objectives: To assess factors associated with self-perception of health in older adults submitted to oral prosthetic rehabilitation in order to contribute to a more contextualized planning of public policies, actions and health services aimed at healthy aging. Design: Analytical cross-sectional study. Setting: Dental specialty centers. Participants: 244 people aged 60 years and older enrolled for oral prosthetic rehabilitation. Intervention: Interviews, oral examination and anthropometric measurements. Measurements: A questionnaire assessed demographic and economic data, general health and oral health and self-perception of oral health-related quality of life was measured by the Geriatric Oral Health Assessment Index (GOHAI). Performance in instrumental activities of daily living was assessed by the Lawton and Brody scale, mood was assessed by the Geriatric Depression Scale and nutritional status was assessed by the Mini Nutritional Assessment. Results: The multivariate analysis showed that factors such as hospitalization in the previous year, diabetes and risk of malnutrition determined the negative self-perception of general health and current health status compared with 12 months ago. Needing assistance to perform AIDL significantly influenced self-perception of general health while income and vision problems interfered with older adults’ perception of their current health status compared with 12 months ago. Conclusion: Older adults who needed oral prosthetic rehabilitation exhibited a predominantly negative self-perception of oral health. http://ijaers.com/detail/factors-associated-with-self-rated-health-in-older-adults-receiving-oral-prosthetic-rehabilitation/ Lucianna Leite Pequeno, Paulo Leonardo Ponte Marques, Maria Vieira de Lima Saintrain, Ilana Nogueira Bezerra, Anya Pimentel Gomes Fernandes Vieira-Meyer, Sandy Kaena Soares de Freitas, José Manuel Peixoto Caldas http://ijaers.com/uploads/issue_files/27IJAERS-04202225-Factorsassociated.pdf Human resilience can be understood as resilience, positive adaptation and overcoming hostile, adverse and/or traumatic situations. This competence is increasingly required of university teachers who are faced with challenges of great magnitude in the workplace. The present study seeks to assess differential manifestations of the resilience of Brazilian university professors. 189 university professors from a private health university in Ceará, Brazil, who answered the Wagnild and Young resilience questionnaire, participated in this research. Results indicate gender differences in assessing self-esteem and personal competence in favor of women; differences in age and seniority indicate that teachers aged fifty-six and over and with eleven or more years of teaching service have higher levels of self-esteem and acceptance of life than younger professors and less experienced; differences in training favor postdoctoral teachers. The results are relevant to the knowledge of this professional group and may contribute to the design of a future cognitive and behavioral training program aimed at promoting resilience in university teachers. http://ijaers.com/detail/differential-manifestations-of-resilience-in-brazilian-university-professors-in-the-health-area/ Maria Regina Teixeira Ferreira Capelo, Christina César Praça Brasil, António José de Olim Marote Quintal, Noémi Serrano-Díaz, Raimunda Magalhães Silva, Elci Alcione Almeida Santos, Mirna Albuquerque Frota http://ijaers.com/uploads/issue_files/28IJAERS-04202239-Differential.pdf This study employed spatial pattern analysis of a prospective dengue epidemic in one of the cities in Nueva Ecija Philippines – Cabanatuan City. It aims to give strategic information for the dengue management effort in the face of constrained capacity. The researchers examined the demographic pattern of dengue cases to add to the knowledge needed for successful policy-making. Weekly records of dengue cases from multiple Disease Reporting Units (DRU) in Cabanatuan City were gathered as the database. This includes barangay, sex, age, and DRU types from January 2014 to December 2018. Each recorded dengue fever patient’s barangay was geocoded to map and clustered. This research found a substantial correlation between reported incidents and particular demographic groupings among male, age 10-14, mostly admitted in a government hospitals and weeks 28 to 42 where the virus transmission is high. Furthermore, the dynamic growth of the aggregation of disease incidence (hotspots) for dengue patients in Cabanatuan City was displayed using spatial analysis utilizing geographic information system (GIS). It is hoped that the research results shall provide strategic information for dengue control program planning and design. http://ijaers.com/detail/spatial-analysis-of-hospitalized-dengue-patients-in-cabanatuan-city-demographics-and-risk/ Ronald S.

A survey of the main Unconventional Food Plants (PANC) used by the peasant community was carried out. Data were obtained using a quali-quantitative approach, taking into account the quantity and variety of unconventional plants that participants indicated they knew and used, and which had potential for food use. The main species indicated by the community, with food potential, were duly identified. Gastronomic workshops were also held, seeking to encourage the use of Non-Conventional Food Plants (PANC-portuguese) and strengthen the sovereignty and food security of peasant families. The main objective was to investigate the factor(s) that lead some people to not use certain plants in their diet, even though they may be suffering from food deprivation and having with the knowledge the feed potential of these plants. http://ijaers.com/detail/agrobiodiversity-and-food-sovereignty-among-peasant-families-in-two-municipalities-in-the-south-of-bahia-brazil/ Alessandra Quirino Bertoso dos Santos Jardim, Angelo Giuseppe Chaves Alves, Paulo Rogério Lopes http://ijaers.com/uploads/issue_files/32IJAERS-04202236-Agrobiodiversity.pdf It is easy to see how animals have been treated over the years by humans, like property, without rationality, objects.

The choice of this topic is justified by the constant violation of the demarcation rights of indigenous lands, the lag in administrative processes, or judicial decisions and bills that do not acknowledge or hamper these rights, as well as the effects of this oversight on the life and demise of indigenous peoples and on nature. The method used was bibliographical-investigative through the use of data from the Social-environmental Institute, the Indigenous Missionary Council, national and international court of laws and current legislation. First, a reflection on the identitary and personal construction of Amerindians is carried out; followed by an analysis of the development of colonialism in Brazil through its effect on traditional territories and peoples; and, finally, numbers and consequences regarding the life and demise of indigenous peoples and the environment are discussed. State negligence concerning the demarcation of these lands is confirmed, as well as the occurrence of violations and violence towards native peoples, along with scarce environmental protection. There is a need for the evolution and reconstruction of concepts and of the legal framework within a decolonial perspective, in order for the full-fledged recognition of indigenous peoples’ rights to take place. http://ijaers.com/detail/human-rights-native-lands-and-environmental-issues-the-demise-of-mother-nature-and-of-the-indigenous-peoples-of-brazil/ Marlei Angela Ribeiro dos Santos, Thais Janaina Wenczenovicz, Émelyn Linhares http://ijaers.com/uploads/issue_files/34IJAERS-04202242-HumanRights.pdf Hydrocephalus is a pathology characterized by the accumulation of cerebrospinal fluid (CSF) in the cerebral ventricles (intercommunicating cavities located in areas of the brain) and in the subarachnoid space between the arachnoid and pia mater membranes of the meninges. The aim of this study was to present a review of the literature, with a contemporary character, on Hydrocephalus and its implications on the central nervous system.

And so, reinforced concrete slabs are no exception to the rule. Still, the usual analysis models for this structural element are verified in the elastic regime when the concrete tensile strength is considered. This model is acceptable for the service limit states but not the ultimate limit state. These aspects associated with the great difference in the behavior of concrete when subjected to tension or compression make it necessary to study a nonlinear mathematical model that can represent a reinforced concrete slab subjected to bending, from the beginning of loading until its failure, as accurately as possible. With this, the ANSYS software, from its version 18, made available in its library the Drucker-Prager-Rankine model arranged with two distinct rupture surfaces. A Drucker-Prager criterion for the concrete subjected to compression and a Rankine criterion for concrete in tension. In addition, the software is based on the finite element method, giving the possibility of precise and nonlinear analysis through load and deformation increments, taking into account both elastic and plastic deformations after concrete cracking. Thus, this work aims to present the modeling of reinforced concrete slabs through the Drucker-Prager-Rankine surface, validating the model by comparing it with several experimental tests. The model results were coherent and acceptable, presenting a good approximation of the results of the tests. http://ijaers.com/detail/nonlinear-analysis-of-reinforced-concrete-slabs-through-the-finite-element-method/ Carlos Henrique Hernandorena Viegas, Mauro de Vasconcelos Real, Eduardo Pagnussat Titello http://ijaers.com/uploads/issue_files/36IJAERS-04202229-Nonlinear.pdf The construction of a construction project often happens something that is not desirable such as the occurrence of delays in work on the project. Many factors cause delays, one way to anticipate it is by accelerating. In accelerating, the cost and quality factors must be considered, so that the optimum cost and quality are obtained according to the desired standard. The construction of the Iain Ambon Library Rehabilitation and Renovation Project was chosen for a research study due to delays in its implementation. The Critical Path Method can be used to schedule project execution time with the consideration that this method is more effective and efficient. The optimization of time and cost is obtained from the Crash Program with the Network Planning system with the Crashing method by adding accelerated working hours for each job. The acceleration is carried out on the work on the critical path with the lowest cost slope. The results of the analysis show that the total project budget under normal conditions is IDR 1,456,082,119 with a duration of 70 days, in the post-crashing condition with the alternative of adding two hours of working hours, it is IDR 2,246,877,528 or more expensive than the total project cost budget under normal conditions. and the duration of the project implementation is 51 working days or faster than the normal duration http://ijaers.com/detail/analysis-of-project-acceleration-with-crashing-method-on-the-rehability-and-renovation-project-work-of-iain-ambon-library/ Ismit Nukuhaly, Rudi Serang http://ijaers.com/uploads/issue_files/37IJAERS-04202220-Analysisof.pdf The analysis of air quality is directly related to the health preservation of individuals who attend closed environments, climatized or not, and this factor can be linked to the place (un)salubrity. Certain polluting factors are potentiated by the lack of natural ventilation; in other cases, depending on the region, the natural circulation of wind is what brings pollution to the place. Considering that all environments can be affected by a sanitary decrease promoted by low air quality, the present work aims to analyze the air contamination indices of the Forum Lourenço José Ribeiro, located in the municipality of Olinda/PE. The methodology uses exploratory research in a case study to be carried out by obtaining quantitative data on carbon dioxide (CO2) indices, internal temperature and relative air humidity that were measured between february and june/2021, in the morning shift of the aforementioned building. The present work is limited to the breadth of the data to be researched, and it should also be considered that the researched period faced the limitation of face-to-face activities motivated by the Coronavirus pandemic, which substantially reduced the amount of exposed and polluting people in the premises Results obtained indicate a good indoor air quality in the evaluated rooms, both for users, servers and occupants of sealed and artificially air-conditioned spaces, with good air renewal.

In this sense, the general objective of the present work is based on evaluating the thematic pertinence of the adequacy of the network implementation for the reuse of water from the dripping of the Forum Lourenço José Ribeiro (Fórum de Olinda) air conditioners, an organ that is part of the Tribunal of Justice of Pernambuco, located in the city of Olinda/PE. The case study is shown as a sufficient methodological apparatus to obtain results, which were evaluated through qualitative and quantitative techniques, intending to achieve a correct understanding of the cost savings with the implementation of drip water treatment of air conditioners in this building that is part of the Pernambuco Court of Justice. Results obtained indicate that the alkalinity of the water from the air condensers could not be used for human consumption, but it is suitable for use in non-noble purposes, such as washing the Forum patios. With this, the reuse of water resources resulting from the dripping of air conditioners is efficient to promote the yield of a natural asset that needs to be used within its maximum capacity, through the appropriate treatment that allows the reuse of the hydric matrix. http://ijaers.com/detail/analyze-condensed-water-quality-a-case-study-in-a-public-building/ Pauline De Albuquerque Gulde, Luiz Filipe Alves Cordeiro, Liliana Andrea Santos, Rafael Rodrigues da Silva http://ijaers.com/uploads/issue_files/39IJAERS-04202246-Analyze.pdf This paper presents the results the study nonlinear vibrations of the three-phase composite shallow cylindrical shell.

The performance level of the plants in the study has been categorized into three main groups. The first group includes the plants which have unit efficiency on CRS, VRS and scale efficiency scores, the second group includes the plants with optimal VRS efficiency but lower scale efficiency, and third group includes the plants with less than unit VRS and scale efficiency. The study observed 7 to 8 plants in first group, 21 to 24 in second in second group, and rest in third group. The mean technical efficiency for the period under study varied from 66.1% to 100% under CRS, VRS and Scale efficiency. The study also revealed the differences in plant level performance both at operator and regional level. The mean technical efficiency has remained more or less same with minor fluctuations but the number of thermal power plants with technical efficiency above the mean technical efficiency shows an increasing trend. http://ijaers.com/detail/plant-level-performance-of-coal-fired-public-sector-thermal-power-generation-in-india/ Satvir Singh http://ijaers.com/uploads/issue_files/41IJAERS-0420228-PlantLevel.pdf
