http://ijaers.com/ Open Access international Journal to publish research paper en-us September Several factors affect the performance, manufacturing, and assembly of metallic profiles: equipment, welding parameters, and consumables. ASTM A36 steel profiles are widely used to obtain high-quality welded joints. Three factors in the welded joints need to remain nearly invariable and within predictable limits: distortion, corrosion, and mechanical properties. However, industries still have problems with welding steel profiles, such as warping misalignment, misfit, and poor mechanical properties. As a result, it is necessary a calibrated and affordable methodology for welding ASTM A36 steel profiles on the factory floor. Therefore, this study aims to analyse the mechanical performance of ASTM A36 steel profile welded joints using a robot welding machine. A GMAW (Metal Active Gas) welding process was applied to an ASTM A36 type U 100 x 50 profile, 3.0 mm thick, employing a Motoman UP6 robotic arm in butt joints, with and without dots. Two different rod electrode types were used (AWS ER70S-3 and ER70S-6), with a 75%Ar/25%CO2 shielding gas and current density welding set at 160.6 A and 20.5 V. A three-dimensional scanning methodology was adopted to investigate welded joint distortions. While salt spray accelerated corrosion test was used to analyse deterioration. The mechanical properties were analysed by macrography, microhardness, and chemical analyses in the Heat Affected Zone (HAZ). It was found a distortion displacement lower than 450 µm on the sample's surface, and a mass loss of 10.1 µm/year was detected in terms of corrosion resistance. There was also evidence of chemical heterogeneity between the base metal and weld, mainly in the manganese content with an average reduction of 13% in microhardness measurements when AWS ER70S-3 electrode was used. By using calibrated welding parameters and a welding robot, it was possible to obtain mechanically resistant high-quality standardised welds. This procedure can be further improved by using other profile types to implement new robotic welding procedures. http://ijaers.com/detail/analysis-of-distortion-corrosion-and-mechanical-properties-of-welded-astm-a36-steel-u-type-profiles/ Josemairon Prado Pereira, Bruno Agostinho Hernandez, Gilberto de Magalhães Bento Gonçalves, Edson Antonio Capello Sousa, Jonatas Martins Pereira http://ijaers.com/uploads/issue_files/1IJAERS-0820234-Analysis.pdf The purpose of this research is to analyze the influencing factors of household income from beef cattle business in the use of artificial insemination and natural mating and evaluate the impact of changes in various external factors on economic behavior, such as the added value of cattle, income from cattle and production costs, allocation of family labor, the income of food crop farming, family income, food consumption, and non-food consumption as well as farmer household savings in the use of artificial insemination and natural mating systems in beef cattle. Further, the measurement of insemination and natural mating employed the approach of inseminator and natural mating costs. This research was conducted using a case study method on 150 beef cattle farmers located in Tababo Selatan Village and Buku Selatan Village, Belang District and Molompar Village and Molompar I Village, Tombatu Timur District, Minahasa Tenggara Regency. Specifically, the study used a purposive random sampling method. Data were analyzed by simultaneous equations, using the two-stage least squares (2 SLS) method and simulated analysis, using the SAS statistical application program. The results show that artificial insemination and natural mating systems had a significant effect on the added value of cattle, increasing the family time allocation of the farmer to the cattle business, production costs, the value of manure production, the rent value of bulls, and the value of unsold cattle. The simulation model demonstrated that an increase in inseminator costs and natural mating costs by 20% could increase the added value of beef cattle, allocation of family working time in the cattle business, beef cattle income, family income of the farmers, and food and non-food consumption. http://ijaers.com/detail/beef-cattle-farmers-economic-behavior-in-the-minahasa-tenggara-regency-indonesia/ Erwin Wantasen, Sintya JK Umboh, Jein R Leke http://ijaers.com/uploads/issue_files/2IJAERS-0820235-BeefCattle.pdf Fraud is an unlawful act committed by individuals, both from within and outside an organization, with the aim of obtaining personal or group benefits that directly harm others. Regional autonomy, which leads to the central government delegating authority to district/city areas, can also transfer the potential for fraud from the center to the regions. One of the government's efforts in preventing and detecting fraud is through audits; however, the performance of fraud detection is highly influenced by professional skepticism, auditor experience, and the limited time provided. This study aims to: (1) Analyze professional skepticism as an antecedent in an auditor's fraud detection. (2) Analyze the level of auditor experience in handling fraud, as not all auditors with experience uncover fraudulent activities. (3) Analyze the moderating role of time pressure in fraud detection. Data were obtained through observation, in-depth interviews, surveys, documentation, and the use of questionnaires. This research is a causal associative study. The total sample collected was 45 individuals, selected using convenience sampling. The results of this study indicate that: 1) Work Experience has a positive influence on Auditor's Ability to Detect Fraud. 2) Professional Skepticism has a positive influence on Auditor's Ability to Detect Fraud. 3) Time Pressure has a negative influence on Auditor's Ability to Detect Fraud. 4) Work Experience, Professional Skepticism, and Time Pressure collectively influence Auditor's Ability to Detect Fraud. http://ijaers.com/detail/antecedents-of-professional-skepticism-auditor-experience-and-time-pressure-in-fraud-detection/ Seri Suriani, Herminawaty Abubakar, Indrayani Nur, Sugiarti Selamet, Abustan http://ijaers.com/uploads/issue_files/3IJAERS-0920231-Antecedents.pdf The achievement of specialist formation necessitates students to be highly determined in order to take part actively in the learning and honing of skills. This article investigates how Artificial Intelligence (AI) can help increase student commitment during their preparation for a specialized field. It is proposed that AI-powered technologies such as virtual assistants, intelligent tutoring systems, and algorithms are able to provide personalized feedbacks, adaptable evaluations, and individualized curriculums which address each learner's particular needs and preferences1. The paper surveys empirical studies as well as theoretical frameworks which present evidence on the advantageous effects of AI on motivation among students including autonomy, competency, and relatedness along with other factors. Moreover; it also delves into possible ethical issues associated with utilizing AI to boost student enthusiasm like data security or algorithmic bias – both must be taken into account carefully so that its integration into education can be done responsibly yet fruitfully. In conclusion; this abstract highlights the necessity for additional research alongside partnership between educators/ researchers/ developers who use AI technology if we want to make full use out of it while stimulating motivation amongst learners thus enabling successful realization of specialist formation objectives. http://ijaers.com/detail/revolutionizing-student-engagement-artificial-intelligence-s-impact-on-specialized-learning-motivation/ Samreen Rizvi http://ijaers.com/uploads/issue_files/4IJAERS-0920232-Revolutionizing.pdf Chagas disease is a chronic health condition with high morbidity and mortality. It has an impact on public health and social and economic aspects, and despite efforts and health surveillance measures, outbreaks of the disease still occur. Objective: To evaluate the epidemiological profile of patients affected by Chagas' disease in Belém between 2015 and 2018. Methodology: This is a cross-sectional, retrospective study based on data collected from the notification and disease system, with data collected on cases in the established period, with information such as schooling, age group and gender. Results: There was a higher prevalence of young patients aged between 20 and 59, with a predominance of males and no correct identification of schooling in the notifications. In addition, there was an increase in the number of cases in 2017, but within the expected level of endemicity. Conclusion: Despite the epidemiological transition and the general decrease in the number of cases, Chagas disease is still an important factor to be evaluated by public health, with preventive policies being maintained, as well as public hygiene and basic sanitation situations. http://ijaers.com/detail/assessing-the-clinical-and-epidemiological-profile-of-patients-affected-by-chagas-disease-in-belem-par-from-2015-to-2018/ Arthur Vinicius Alves Maciel, João Vitor Oliveira Moraes, João Vitor Rezende dos Santos Sabola, Luan Monte Pereira, Maria Eduarda Rendeiro Furtado, Pedro Raimundo Cunha Silva, Elaine de Oliveira e Silva, Maria Clara Almeida Sadala dos Santos, João Vitor Tavares da Costa, Edyane Oliveira e Silva, Emanuela Bandeira da Silva, Isabela Lacerda Avila, Juliane dos Santos Costa, Pedro Thiago Malcher de Amorim Dias, Lara Rosa Cardoso e Cardoso, Danielle Lima Barbosa, Manuella Ferraz de Souza Monteiro, Joely Lúcia de Souza Rodrigues, Enaile Dias Pontes, Vittória Marques Bigatão, Gabrielle de Freitas Nogueira, Gabriela Mutran dos Anjos, Valeria Pereira Rezende de Almeida, Silvia Kelly Jacques Sousa de Assis, Thais Costa Valente, João Lucas Barbosa Nery Marques, Daniel Rêgo Sousa, Lucas Stoessel Klautau Sadala, Dienyelle de Nazaré Costa Barbosa, Magno Ferreira da Silva, José Victor Silva Lima, Fabio Andres Ayala Neri, Edmilso Lopes Cabral, Naylane Sousa Pinheiro, Maria Helena Rodrigues de Mendonça http://ijaers.com/uploads/issue_files/5IJAERS-08202311-Assessing.pdf With the increasing increase in the world population there was a need for a greater supply of food for consumption. In order for farmers to have greater productivity, more profits and exports, they started to use pesticides on their plantations, making excessive use of this product. Knowing the damage that this product can cause, the objective of this work was to compare the research published to date on the possibility of the presence of pesticides in food and natural resources, in addition to their possible influences on the environment and the health of the population. The method used to develop this work was a bibliographical review on the topic of pesticides, the damage to the environment and human health due to their intensive use. The results obtained from the authors cited on the intensive use of pesticides are the risks of diseases in men such as cancer, infertility, impotence, miscarriages, among others. There is also a risk of contamination of breast milk and the birth of babies with autism. In the environment, there is contamination of soil, water, air, food and malformations and death of animals. In order to minimize the impacts of pesticides on the environment and human health, the correct use of this product is necessary, using them according to the leaflet, in the correct dosage, in addition to the correct disposal of packaging and aerial spraying at the limit according to the relevant law. This way you can have a better quality of life and thus preserve the environment for current and future generations. http://ijaers.com/detail/consequences-of-excessive-application-of-pesticides-and-impacts-on-the-environment-and-human-health/ Fernando Ernesto Ucker, Tarek Chaher Kalaoun, Renan Krupok Matias, Fábio Henrique Casarini Gerônimo, Leticia Chaves Fonseca Ucker, Dhiene Leão Silva http://ijaers.com/uploads/issue_files/6IJAERS-09202312-Consequences.pdf Global concern about climate change is present in different segments of society. These changes can also be measured by, for example, air quality standards in urban centers. The objective of this work is to monitor and analyze the amount of carbon monoxide of vehicular origin due to the burning of non-renewable fuels around the Vaca Brava Park, and to evaluate the consequences that this pollutant brings to the health of the population and to the environment. Park Vaca Brava is in the municipality of Goiânia, has an area of 79,890.63 m2. Samples were taken at three points in the Park, in the main busiest avenues in its surroundings, and the fourth sample was carried out inside the Park to compare the amount of carbon monoxide with the other points. These points were chosen because they present a large volume of people that pass in the place for the practice of physical exercises, and also for having a large agglomeration of vehicle in its surroundings, as a result of the commerce being quite busy in this region, due to this, the traffic vehicle is quite intense. In the period of study carried out in the park, there was a small change of this pollutant in November 2022, February, March and May 2023, in the other months no CO value was detected. It was also observed that the values of carbon monoxide in most of the months studied were not detected by the device. The green area of the park is quite important to regulate the air quality in this region and make it fresher and healthier for those who frequent the place. http://ijaers.com/detail/analysis-of-air-quality-in-parque-vaca-brava/ Fernando Ernesto Ucker, Tarek Chaher Kalaoun, Renan Krupok Matias, Fábio Henrique Casarini Gerônimo, Leticia Chaves Fonseca Ucker, Rosane de Paula Castro, Elisângela de Souza Silva http://ijaers.com/uploads/issue_files/7IJAERS-09202313-Analysis.pdf
