However, in LEACH protocol the criteria for clustering and selecting cluster heads (CHs) nodes were not mentioned. In this paper, we propose to improve the LEACH protocol by combining the use of K-means algorithm for clustering and bat algorithm (BA) to select nodes as CHs. The proposed routing algorithm, called BA-LEACH, is superior to other algorithms, namely PSO-LEACH, which using particle swarm optimization (PSO) to improve LEACH. Simulation analysis shows that the BA-LEACH can obviously reduce network energy consumption and optimize the lifetime of WSNs. http://ijaers.com/detail/improvement-of-leach-based-on-k-means-and-bat-algorithm/ Trang Pham Thi Quynh, Tuyen Nguyen Viet http://ijaers.com/uploads/issue_files/6IJAERS-01202145-Improvement.pdf Poor conditions at sugar and other plantations in the Pacific Oceans as study territory or area tells, led to the outbreaks of disease and deaths in massive rate or amount.

Chlorhexidine has been used in endodontics due to the wide spectrum of action. However, associated with other irrigation solutions can form Parachloroaniline (PCA), a possible carcinogen for humans, according to the IARC (International Agency for Research on Cancer). The aim of this study is to analyze the formation of PCA through protocols that associate irrigation solutions in chemical-mechanical preparation. Fifty lower premolars teeth extracted from humans were selected, then separated into 5 groups (n=10) for 5 different irrigation protocols and at the end were microscopically analyzed. According to the results obtained only the irrigation protocol of group 5 had the formation of PCA in the three thirds of the root. http://ijaers.com/detail/analysis-of-parachloroaniline-formation-through-protocols-of-associations-between-irrigating-solutions-during-chemical-mechanical-preparation/ Glaucejane Oliveira da Silva, Eduardo Fernandes Marques http://ijaers.com/uploads/issue_files/8IJAERS-01202115-Analysis.pdf Abstract: Basic education is going through a transformation moment, in some states in Brazil schools are already implementing a new curriculum. Discussions of the new National Common Curricular Base are part of the teaching routine and in the case of federal institutes, the reformulations of pedagogical course projects are taking place on the various campuses. However, regardless of the result of the work of the commissions, the institutional pillars will be observed: the integration of teaching, research and extension. And it is in this scenario that we sought to analyze the teaching and student perceptions regarding the contributions of extracurricular activities in the integral formation and the protagonism of the IFRO Campus Porto Velho Calama student. Methodologically, a qualitative research was developed, based on a bibliographic study and field research using a semi-structured interview with 26 professors and 118 students. The results incited multiple perspectives regarding this relationship between extracurricular activities and income. http://ijaers.com/detail/extracurricular-activity-and-vocational-technical-training-meetings-and-meanings-in-integrated-technical-teaching/ Iranira Geminiano de Melo, Elizângela de Souza Bernaldino, Clarides Henrich de Barba http://ijaers.com/uploads/issue_files/9IJAERS-01202133-Extracurricular.pdf As 20 January 2021, there have been 94,963,847 confirmed cases of COVID-19, including 2,050,857 deaths, reported to World Health Organization (WHO). The outbreak of coronavirus disease (COVID-19) creates significant impact to economy activities in worldwide. Most economic sectors including tourism industry facing with difficulties during the outbreak of COVID-19. The COVID-19 outbreak creates negative effect and slow down all economic activities in worldwide. This disease spread easily that transmitted through droplets generated when an infected person coughs, sneezes, or exhales. Therefore, in surviving for global economy, a few pharmaceutical companies developing vaccine to cure the disease. Vaccines function by training and preparing the immune system of human body, to recognize and fight off the target viruses and bacteria. If the body is exposed to those disease-causing germs later, the body is immediately ready to destroy them, preventing illness. This paper analyzed the demand-supply of COVID-19 vaccine towards price and quantity. Result shows the increments in demand for vaccine, creates increments in price of vaccine.

Although the solar modules are located on roofs and lightning strikes can damage all components of PV System (PVS). The Lightning Protection Systems (LPS) associated with Surge Protection Device (SPD) are the effective protection against electromagnetic effects. This study estimated the values of overvoltage and overcurrent induced by lightning in 2.65 kW PVS under different configurations, with or without LPS, by Faraday's Law of Induction. The estimation of the difference of potential on soil is according to the Law of Ohm and Maxwell equation. Thus, the purpose of this publication is to support the LPS design and SPD specification for PVS. The simulation considered the DC wiring design, distances from LPS and tilt angle of solar modules. The results pointed out that impulse rate of 200 kA/µs induces peaks up to 201,6 kV and 28,3 kA in DC circuits by lightning strikes and up to 82 kV in AC terminals of DC/AC converter transferred from soil by grounding systems. In conclusion, the main protection system against lightning damages is LPS associated with SPD that can protection against abnormal values of induced voltage and current. In addition, equipotentialization is necessary to complement the effective protection using a unique grounding system in accordance with the guidelines of the international standards IEC and ABNT. http://ijaers.com/detail/lightning-protection-of-rooftop-photovoltaic-systems-a-scientific-approach/ Swytz Jose Silva Tavares, Francisco Hedler Barreto de Lima Morais, Caike Damiao Nascimento Silva, Ricardo de Castro Gomes, Lya Serpa Claudio dos Santos, Francisco Geraldo de Melo Pinheiro, Lutero Carmo de Lima http://ijaers.com/uploads/issue_files/11IJAERS-02202111-Lightning.pdf The advent of digital transformation, also known as Industry 4.0, has brought considerable challenges to organizations from various industries. The effects of its relevance and intensity can be observed in the relations between organizations, between individuals and the first and governments with these two entities. By encompassing the intense use of information and communication technologies (ICTs), it raises the need for careful evaluation and selection of projects aimed at digitally transforming, business processes, business models and customer experience to interact with the first two. In this sense, portfolio management which includes the evaluation and selection of projects, has numerous methods of analysis ranging from financial tools to strategic approaches. Therefore, selection of the method directly influences the quality of the decision made, as well as obtaining the optimal portfolio of projects. This study is dedicated to exploring the use of scenarios to support the analysis and selection of digital transformation projects. This research is qualitative, exploratory, descriptive in nature and is structured through ground theory method (GTM) applied in 7 (seven) Brazilian telecommunications operators. The main contribution of this study is the proposition of a framework that integrates prospective scenarios of evaluation and selection of projects in organizations in a structured manner helping them to conduct their digital transformation, through the creation of digital capabilities. http://ijaers.com/detail/evaluation-and-selection-of-scenario-based-digital-transformation-projects/ Alexandre Caramelo Pinto, Alexandre Acácio de Andrade, Julio Francisco Blumetti Facó, Jadir Perpétuo dos Santos http://ijaers.com/uploads/issue_files/12IJAERS-0220213-Evaluationand.pdf The evolution of space missions and related systems has been promoting innovation and creation of ideas for new technologies for decades.

Isolators are very influential on environmental conditions such as temperature, humidity and other pollutants. A suitable testing condition is needed to ensure the insulator will do properly. Therefore, it is necessary to test the insulator at a similar actual environment. This test is carried out using a chamber with temperature and humidity settings to determine the characteristics of the leakage current in the insulator.In this paper, a PID Controller is implemented to control the temperature in the chamber. The PID controller is applied in the Arduino R3 microcontroller using a DHT22 sensor and a thermoelectric cooling actuator (TEC12706.) Experimental results show that the PID controller can maintain the chamber temperature at the desired setpoint with Kp = 200, Ki = 10, Kd = 5. The system can reduce the temperature up to 23.6 °C with a rise time of 198 seconds with a peak time of 218 seconds at a temperature of 24.8 °C.The system can reach at apreset temperature value with a response time of 32 seconds. http://ijaers.com/detail/pid-controller-implementation-for-temperature-control-in-leakage-current-test-chamber-20kv-insulator/ Agung Nugroho, Trias Andromeda, Munawar Agus Riyadi http://ijaers.com/uploads/issue_files/14IJAERS-01202140-PIDController.pdf The institutional theory provides a greater understanding of organizational phenomena, especially in relation to the reaction of organizations to the pressures of the environment in which they operate. These pressures, which can be mimetic, coercive, and normative, force companies to become increasingly homogeneous, through isomorphic mechanisms, and can even influence the search for exploratory and exploitative knowledge. This study was carried out with the intention of verifying how the pressures exerted by organizational isomorphism affect the search for knowledge. The study was conducted in the underwear companies of APL Taquaral in the state of Goiás Brazil. The results revealed that the organizational isomorphism does exert some pressure on the companies of APL in its three forms. As to whether it influences the search for knowledge, it was demonstrated that the influence of exploitative knowledge is quite noticeable and the exploratory knowledge practically does not occur. The companies demonstrated technical and or financial inability to invest in R&D, which occurs because of the characteristics of the companies of the pole, in addition to the evident lack of public policies. http://ijaers.com/detail/institutional-theory-and-the-isomorphic-pressures-in-the-search-for-knowledge-a-study-in-an-apl-of-goi-s-brazil/ Vailson Batista de Freitas, Marco Antonio Pinheiro da Silveira http://ijaers.com/uploads/issue_files/15IJAERS-0220217-Institutional.pdf A fast cooling process is needed to maintain the quality of the fish caught. In this research, the chilling system insulated hatch using refrigerant with a capacity of 80-100 kg for a 3 GT sized vessels. The insulation hatch is bolted from fiber material where the walls are cast with polyurethane material. Polyurethane consists of 2 (two) types, namely A and B, where when the two materials are mixed it will expand and form insulation. This hatch making research uses a trial and learn system. To be able to draw heat from the cooling room, the evaporator with a coil length of 30 meters is specially designed, that is, it is wrapped around the shape of the hatch and attached to the aluminum plate. The length of the capillary pipe used is 3.00 cm with a diameter of 0.26 to produce a load temperature of 20C - 4.40C. The test of the chilling system insulation using refrigerant was carried out at the cooling workshop SUPM Waiheru Ambon. The test materials used were sea water as much as 84 kg / L and whole tuna fish with a size of 28 kilograms.

So, the objective of this paper is to jointly discuss project management, megaprojects and the challenges of managing this kind of project. First, we review the project management concepts and standards; then we define megaprojects, considering that a narrow definition is not the best alternative and then we present the current discussions about managing megaprojects. As a conclusion, we suggest unfolding the emerging topics for managing megaprojects in specific process, documents, tools and templates, to create a new standard, otherwise project managers will keep unsuccessfully trying to adapt the traditional methodologies to their megaprojects.

In this context, this work seeks to discuss the changes at Nº. 12,651/2012 law, brought to the small rural producer, showing the APPs, the Legal Reserve areas and the Registration with the CAR. The research methodology was developed through critical bibliographic analysis of legislation, periodicals, doctrines, and books. As a result, it was demonstrated that the forestry legislation recognized the importance of small family farmers, granting different treatment. It is noticed that the Brazilian Forest Code Legislation was instituted to apply the reality experienced by small producers in land use, which must make development compatible with the preservation of biodiversity. http://ijaers.com/detail/the-repercussion-of-the-brazilian-forest-code-in-the-small-property-of-family-agriculture/ Lizziane Coelho Carvalho May, Rildo Mourão Ferreira, Alberto Barella Neto, Elza Soares Batista Mourão http://ijaers.com/uploads/issue_files/20IJAERS-02202115-TheRepercussion.pdf The objective of this work was to investigate the treatment of the theme Environmental education in a transversal way with the students of the 1st periods of the courses of Buildings and Integrated Sanitation of the IFPE (Federal Institute of Education, Science and Technology of Pernambuco) - Campus Recife, under the perspective of awareness of these students, with mathematics as an important aid tool. The survey took place in July and August 2020, where questionnaires were applied through Google Forms to 80 students. In a second step, another form was sent to the teaching segment, in a total of 50 questionnaires. The questions addressed in the questionnaires to students led to points such as the perception of the existence of environmental problems, also seeking to analyze the degree of understanding of students in relation to mathematics as a support to environmental education. Subsequently, tabulation, statistical treatment and analysis of the data obtained through descriptive statistics were performed. The results revealed that a significant portion of the students came to understand that the environmental issue is not only a matter of nature, but also of society. Although, it should be noted that some of them can better understand what an environmental problem is than fully understand what the environment is. As for the professors, they demonstrated to relate to the current reality of the planet, however, a portion of this segment suggests that the structure of work to approach the theme is not so adequate. http://ijaers.com/detail/diagnosis-of-the-knowledge-of-students-and-professors-about-environmental-education-case-study/ Luiz Henrique de Souza Silva, Daniele de Castro Pessoa de Melo, Eduardo Antonio Maia Lins, Luís Filipe Alves Cordeiro, Wanderson dos Santos Sousa http://ijaers.com/uploads/issue_files/21IJAERS-02202117-Diagnosis.pdf Objective: to report the experience of applying nursing care systematization to a Newborn with congenital malformation.

The CO2 geological storage, inherent to Carbon Capture and Storage (CCS) activities, is characterized as an effective mitigation option to reduce the levels of this gas in the environment. The risk assessment allows the identification of the most significant risks and impacts, respecting the facilities characteristics, the geological conditions of the basin and the associated natural processes, assisting to propose measures that reduce the probability or the magnitude of their occurrence. Then, this analysis requires an understanding of the stages of the frameworks for Risk Assessment of CO2 storage streams in geological formations of the main international organizations, based on studies of the literature reviewed for these purposes.

The results obtained were the verification of the scarcity of works aimed at the adult phase of human development, and numerous references about the social representations of sexuality in the elderly, showing the sexual repressions suffered by them by society, which we could also see In the interviewees' discourse, such as: prejudices, guilt, changes, needs, wants, fears, etc. Our intention to know the representations of the sexuality of this public and the possible changes in sexual practice was limited, mainly due to the scarcity with regard to scientific articles aimed at adult and elderly life from the perspective of the Freudian genital phase, due also to little knowledge that the public had on the subject of sexuality, it became evident that there is confusion between sexuality and sex itself, impairing the evaluation of responses, and also due to the number of participants who joined the survey, even so, this points to the importance to open research on this topic. http://ijaers.com/detail/human-sexuality-in-the-life-of-adults-and-the-elderlys-report-of-a-field-study-in-porto-velho-rond-nia-brazil/ Leonardo Severo da Luz Neto, Carlos Alberto Paraguassu-Chaves, Luiz Carlos Cavalcanti de Albuquerque, José Arilson de Souza, Jasmine Paz Cruz, Ana Paula Farias, Janaína Gianne Araújo Medeiros, Jéssica Oliveira Santana, Mariana Oliveira Silva http://ijaers.com/uploads/issue_files/25IJAERS-02202114-HumanSexuality.pdf Despite advancements in recent years concerning the universalization of access to Basic Education, when dealing specifically with students with a disability, one notes that the effective inclusion of such students is still a great challenge. The inclusion of deaf students in physical education classes, for example, is a growing trend, yet there is still a glimpse of a sensitive gap in the promotion of equal and qualified inclusion due to the difficulties and problems that constantly appear in the process of teaching and learning. The methodology adopted in this research is based on a qualitative approach, configured in terms of basic research with an exploratory objective. Data collection procedures were carried out via bibliographic and patent research. We identified a total of 164 records on the subject (11 references, 16 rare periodicals and 137 general works). However, none of these records are related to sports or to the theme of the project in question (glossary in Libras of technical gestures for handball teaching). In the patent bases, no occurrence was identified for a product similar to the one proposed to be researched. The creation of a technical manual in Libras with technical gestures of handball would minimize these language barriers between physical education teachers and deaf students. As previously explained, the main objective of this research was to analyze the relevance of using educational resources in Libras for technical gestures, equipment and specific terms of handball as a tool to assist in teaching this sport to the student community with hearing-impairment. http://ijaers.com/detail/accessibility-of-hearing-impaired-people-at-ifpb-through-an-educational-resource-in-libras-for-the-practice-of-handball-sportive/ Emmanuel da Paixão Neto, João Ricardo Freire de Melo http://ijaers.com/uploads/issue_files/26IJAERS-02202119-Accessibility.pdf Using strategic management aspects can be very beneficial specially in decision making process.

The finite elements analysis and the strain gauge methodologies were used for the numerical analysis of the generated stress and the microstrain around the implants and their connections. Two implant models with the same length (13 x 3.75 mm) were analyzed according to the prosthetic connection: external hexagon or morse Taper. Both abutments received screw-retained metallic crowns in chromium-cobalt. The peri-implant tissue was simulated using polyurethane resin in two different heights (bone level and 5 mm of bone loss). A load of 300 N was applied on the occlusal surface. The results were analyzed in terms of von-Mises stress and micro strain. Samples identical to the numerical models were made for the Strain Gauge (SG) analysis; four SGs were bonded around the implant to obtain micro strain results. Finite element analysis and strain gauge corroborated in terms of similar mechanical response. Thus, there is no difference regarding the prosthetic connection for the generated stress and strain under axial load. However, bone loss increased the stress and strain magnitude for both prosthetic connections. In conclusion, both evaluated implant connections present similar biomechanical behavior regardless the bone height. http://ijaers.com/detail/the-effect-of-different-bone-level-and-prosthetic-connection-on-the-biomechanical-response-of-unitary-implants-strain-gauge-and-finite-element-analyses/ Carlos Eduardo Datte, Vinícius Anéas Rodrigues, Fabiana Barbi Datte, Guilherme da Rocha Scalzer Lopes, Alexandre Luiz Souto Borges, Renato Sussumu Nishioka http://ijaers.com/uploads/issue_files/28IJAERS-02202125-Theeffect.pdf The esthetic demands have increased considerably over the years in the routine dental practice. Facial harmony is directly related to the smile, which is formed by the combination of three components: teeth, gingiva and lips. The excess gingival exposure, commonly described as "gingival smile", has received greater emphasis in Dentistry in the last years and has been the complaint of many patients, because this situation can influence the self-esteem and social relationships. It is fundamental to establish the correct diagnosis of gingival smile to allow a specific therapy for the patient. This paper presents, by a case report, the esthetic and functional scope by a multidisciplinary approach with association of correction of gingival smile and placement of esthetic ceramic crowns. The interaction between Periodontology and Prosthodontics proved to be essential to achieve health and harmony between dental and periodontal tissues, allowing to meet the patient's expectations, optimizing the esthetic and functional result, besides providing longevity. http://ijaers.com/detail/esthetic-functional-multidisciplinary-rehabilitation-case-report/ Gleicy Kelly Campoy, Jocarla Alves dos Santos, Rachel Gomes Eleutério, Fernando Accetturi, Marcílio Félix, Daniele Raineri Mesquita Serva Spressão, Daniela Vieira Buchaim, Rogério Leone Buchaim, Eliana de Souza Bastos Mazuqueli Pereira http://ijaers.com/uploads/issue_files/29IJAERS-02202122-Esthetic.pdf Big Data is a crucial component not only to support business decisions, but to gain competitive advantage in an increasingly globalized world, where those who have more information are one step ahead, in this concept companies like technology companies like Facebook, Google and traditional manufacturing companies are making high investments in Big Data and Advanced Analytics with the challenge of translating this huge volume of data. This research effort aims to map the challenges that traditional Manufacturing Industry companies must take advantage of the potential of Big Data and Advanced Analysis to generate real value for the Business through a case study of a global technology company. We found that despite the professionals working on technological development, they understand that the generation of value and the lack of strong evidence of how much Big Data is adding to the current scenario of the Manufacturing Industry was one of the biggest motivations behind this research, which after the case study carried out gave a clear understanding that the manufacturing industry is not prepared to make the most of this new era of Analytics. Another important fact revealed by the surveys is the common concern about the need to invest in improving the competence of the resource in any organization to explore the Big Data environment. http://ijaers.com/detail/the-manufacturing-industry-and-the-big-data-challenges-the-case-study-of-the-global-tech-company/ Cezar Honorato, Francisco Cristóvão Lourenço de Melo, Reinaldo Cesar de Morais http://ijaers.com/uploads/issue_files/30IJAERS-02202131-TheManufacturing.pdf In this work we aim to develop a Potentially Meaningful Teaching Unit (PMTU), capable of satisfying the interests and theories of meaningful learning. Using interdisciplinarity to make classes more attractive and a better transfer of information in order to form the concepts of teaching energy. Methodologically the research has a qualitative approach. Focused on the formation of the PMTU, before discussing the concepts of Physics and Mathematics, students are worked on a conceptual map produced by them, from the topic Energy Generators, making it possible for the teacher to observe the previous knowledge of each student regarding the theme. After all the content has been worked on, the proposal is to create a new conceptual map using the same theme of analysis, so that the teacher can observe whether the student has incorporated the fundamental concepts in his knowledge and for himself to evaluate his classes. http://ijaers.com/detail/potentially-meaningful-teaching-unit-building-mathematical-problems-involving-power/ Antonio Vanderlei dos Santos, Marcelo Paulo Stracke, Graciela Paz Meggiolaro Dal Molin, Carlos R.

According to a philosophical context about environmental problems and the evolution of norms that protect nature, due to the ineffectiveness of environmental penal alternatives, it is possible to understand that a punitive measure of an educational and socially useful character is necessary, since everything that involves man and the environment must be seen according to a metaphysical-ontological construction, since they cannot be separated, due to the fact that it composes nature itself. Thus, it concludes that it is possible to include the Reflective Groups as a more viable criminal alternative to the educational context when committing environmental crimes, whether by individuals or legal entities. Although not included in specific legislation, it is certain that this is the most viable alternative because it provides the person in prison with the opportunity to promote environmental awareness and education. http://ijaers.com/detail/reflective-groups-viable-and-necessary-environmental-penal-alternative/ Angela Issa Haonat, Angelo Ricardo Balduino, Silvânia Gonçalves de Carvalho, Oseias Costa Rego http://ijaers.com/uploads/issue_files/34IJAERS-02202138-Reflective.pdf The paper aims to present the results of an assessment of adherence to the Deep Q-learning algorithm, applied to a vehicular navigation robot.

Thus, learning science at school today is of fundamental importance for students to be able to understand its concepts, as well as to apply them. However, due to the lack of methodologies as regards Teaching Chemistry to deaf alumni and the scarcity of scientific terminologies in this area, which impact on the learning of this science, many authors point out the need for research involving chemical signs in Libras. In this sense, this article aims to make a mapping to know if there are Signs in Libras for inorganic compounds in audiovisual format, as material to aid the translation of scientific concepts. The methodology was based upon a qualitative approach of exploratory nature, with data collection via bibliographical research. The prospecting was accomplished on CAPES portal, Google Scholar and SciELO, there resulting in 6,476 documents. After filtering strategies, we found that none was identical to the desired product. We therefore identified that there are no articles, dissertations and theses, up to this research date, addressing to the theme of Libras for inorganic compounds and that their creation is of fundamental need for understanding the chemical concepts and, consequently, as a tool to support the chemistry teaching-learning process. http://ijaers.com/detail/signs-in-libras-for-inorganic-compounds-as-a-translator-of-scientific-concepts-a-prospection-in-bibliographic-databases/ Maria da Conceição Silva de Melo Caracol, João Ricardo Freire de Melo, Frederico Campos Pereira http://ijaers.com/uploads/issue_files/37IJAERS-02202136-Signsin.pdf The operation of the Jirau hydroelectric plant, in the Madeira River near Porto Velho, Brazil started in 2013. Increased flooding areas near Jirau dam periodically reach communities with poor sanitation and can result in health problems, as the propagation of tropical diseases transmitted by aquatic vectors. Thus, we investigated the relationship between flooded areas and cases of malaria in Jirau´s Administrative Regions between 1994 and 2015. The flooded area was determined through spectral data (Landsat-5 and Landsat-8 satellite) and the numbers of malaria cases were extracted from the Epidemiological Surveillance Information System database of the Brazilian Ministry of Health. We verified an average flooded area of 770.3 km² before the dam (1994-2013) and 1370 km² after its operation (2014-2015). With linear regression between malaria cases and flooded areas, we verified a negative correlation during the study interval. Despite greater average flooded area after dam operation, the reduction of cases may be a result of several factors such as the imbalance of the parasitic relationship due to microclimatic changes, application of new substances for biological control (like artemisinin derivatives), little time for vector adaptation into new breeding sites, presence of plasmodium asymptomatic carriers, or even gaps or lack of case records in epidemiological databases. We highlight the importance of continuous monitoring of these variables and social control actions coverage expansion to prevent the risk of epidemic cycle occurrence and guarantee health security concerning this tropical disease and its socio-economic consequences. http://ijaers.com/detail/relationship-between-the-flooded-area-and-cases-of-malaria-disease-before-and-after-construction-of-jirau-hydroelectric-plant-madeira-river-brazil/ Johnatan Almeida de Sousa, Christiano Luna Arraes, Bruno Ferezim Morales http://ijaers.com/uploads/issue_files/38IJAERS-02202137-Relationship.pdf Lean Manufacturing (LM) is a philosophy that allows companies to be elevated using their tools and contribute to the improvement of sectors. Therefore, it is necessary to adopt this system in order to continuously improve it, therefore, the general objective of this research was to analyze the feasibility of implementing the lean manufacturing tool in a valve spring inspection and packaging cell. To do this, specify the following specific objective, determine a method capable of increasing production capacity through LM, in order to increase competitiveness and profitability and evaluate the time results provided by LM. An action research was carried out to understand the benefits of applying this study in an inspection and packaging cell through the use of practical activities in company X. The results show that using tools such as the Ishikawa Diagram it is possible to use the cause root of the problems, thus allowing to develop actions to solve the problems. Thus, it was possible to verify that, when discovering the problems, it can increase by about 15% in area 1 and 9% in area 2. http://ijaers.com/detail/application-of-lean-manufacturing-to-reduce-unproductive-times-in-a-valve-spring-inspection-and-packaging-cell/ Cleginaldo Pereira de Carvalho, Luiz Edvaldo Leite http://ijaers.com/uploads/issue_files/39IJAERS-02202121-Applicationof.pdf Systemic arterial hypertension or high blood pressure is a disease that affects many people in the world and is considered a relevant factor in establishing the cause of death. Arterial hypertension is when the pressure that the blood exerts on the walls of the arteries to move is very strong, being above the values considered normal. In addition, this disease involves hardening of the vascular walls, which makes it difficult for blood flow to pass. Therefore, the general objective of this work is to evaluate the existing literature, in order to verify dental care for hypertensive patients. The methodology used was a review of the integrative literature, which searched material databases that supported the theme addressed here. After this survey, 13 articles made up the research results. It is concluded that in the case of diagnosed and treated hypertension, the dentist should consult the patient's doctor, when starting the treatment plan, to make possible the integration of the medical and dental treatments. These patients can be submitted to non-surgical treatments using normal methods, and in case of simple surgical procedures, complementary sedation should be used. http://ijaers.com/detail/dental-management-in-hypertensive-patients/ Ana Cristina Silva de Souza, Maria Luiza de Freitas Pereira, Gabriela Meira http://ijaers.com/uploads/issue_files/40IJAERS-0220214-Dental.pdf Introduction: The disease SARS-CoV-2, named COVID-19, was officially declared a pandemic by the World Health Organization on March 11th, 2020. SARS-CoV-2 contains a single-stranded, positive-sense RNA genome surrounded by an extracellular membrane containing a series of spike glycoproteins resembling a crown. Neuropsychiatric manifestations are common during viral pandemics but are not effectively addressed. Case Report: We report the case of a man, 42 years old, who after the infection by SARS-COV2, presented dysnomy, cognitive easing and errors in motor processing. Results and Discussion: Studies have shown the neuroinvasive capability of SARS-COV2, resulting in neurological complications. Common neurological symptoms are headache, dizziness, anosmia, dysgeusia, mental confusion, and muscle weakening, progressing toward severe complications like cerebrovascular disease, seizures, muscle pain, and Guillain-Barre syndrome. The patient in the present case, about seven days after the initial infection, began to have difficulties in naming basic objects and "cognitive" slowness in the performance of basic and instrumental activities of daily life, especially those that required mutual tasks and that required concentration. Patients may be at higher risk of developing cognitive decline after overcoming the primary COVID-19 infection. Neuroinvasive capacities and neuroinflammatory events that may lead to the same short- and long-term neuropathologies that SARS-CoV had shown in human and animal models. The presence of dementia, minimal cognitive impairment and problems with motor planning and execution has been described. Conclusion: A structured prospective evaluation should analyze the likelihood, time course, and severity of cognitive impairment following the COVID-19 pandemic. http://ijaers.com/detail/dysnomy-and-executive-processing-errors-of-sars-cov-2-post-infection/ Marco Orsini, Jacqueline F.do Nascimento, Nicolle Nunes, Antonio Marcos da S.

However, with the potential of this class threatened by excessive and unnecessary use, associated and emerging infectious diseases arose due to the ineffectiveness of antibiotics. Bacterial resistance has become a public health problem. This paper aims to track a health care unit profile focused on medical care in a BHU in Salvador-BA, Brazil, through a descriptive exploratory study. Identifying the main antibiotics in use, if there are interactions with continuous use drugs, analyzing the factors that contribute to bacterial resistance and discussing the importance of the pharmacist in guiding the use of this class. A literature review conducted from Scielo, Journal of Public Health, WHO, ANVISA support the elaboration of a questionnaire applied to 150 participants from the community covered by the study in health unit after consent by signing the Informed Consent Form. The participants cited eight types of antibiotics, among which there was a prevalence of beta-lactams, and five types of antihypertensive drugs associated with antibiotic use. The analysis of the results identified some drug interactions. Thus, it is necessary to strengthen health education strategies, since the drug dispensing involves until the instructions given to the patient, to minimize the consequences of misuse of this class and avoid cases of bacterial resistance. http://ijaers.com/detail/the-use-of-antibiotics-and-the-contribution-to-the-increase-in-bacterial-resistance-a-perspective-from-a-research-in-a-health-unit-in-salvador/ Thaís Sento Sé Brandão de Oliveira, Bruna Oliveira do Nascimento, Isleide da Silva Santos, Juliana Azevedo da Paixão http://ijaers.com/uploads/issue_files/42IJAERS-02202144-Theuse.pdf This article makes a brief analysis of the discursive resources used as scientific dissemination strategies through journalism in the institutional newsletter Jornal do Semi-Árido, conceived, produced and edited by EmbrapaSemiárido's press office.
