Inventory Automation Using RFID Technology in Romaster Engenharia
No full textThe inventory of assets is something common and very common in companies annually or even every semester, it is an essential factor for a large and medium-sized company. The large number and degree of complexity of the assets that a company has directly affects the difficulty of managing these assets and, of course, the definition of an accurate inventory. We are talking about a large amount of assets, not just to be on paper and registering one at a time takes a long time, so the idea of our article was to automate all the company's assets (Romaster) by tags, and install antennas at points strategic to make an accurate reading of the company's assets, thus optimizing the inventory time. This technology has existed since the last century, used for the most diverse purposes, but now inserted in the inventory management of the Romaster company
A comparison of the Normal and Laplace distributions in the models of fuzzy probability distribution for portfolio selection
No full textThe propose of this work is applied the fuzzy Laplace distribution on a possibilistic mean-variance model presented by Li et al which appliehe fuzzy normal distribution. The theorem necessary to introduce the Laplace distribution in the model was demonstrated. It was made an analysis of the behavior of the fuzzy normal and fuzzy Laplace distributions on the portfolio selection with VaR constraint and risk-free investment considering real data. The results showns that were not difference in assets selection and in return rate, however, There was a change in the risk rate, which was higher in the Laplace distribution than in the normal distribution
A Comparison of Quarterly Performance in Science of Grade 7 Students in Public School
No full textIn a typical science curriculum with different scientific disciplines (Chemistry, Biology, Physics and Earth Sciences) taught in every quarter, it is important to determine the difference in the performance of students under each discipline. In this study, the comparison of quarterly performance in Science of Grade 7 Students was examined. Wherein, the consolidated quarterly grades in science from the previous school year (June 2018 - April 2019) from five sections with a total of 272 male and female grade 7 students were used as data. It employed a quantitative research design using a One-way Analysis of Variance ( ANOVA) to determine the significant difference in the mean grades per quarter. Additionally, an interview with the science teachers who handled the samples was conducted to gather qualitative data to further explain the results. The results of this study revealed a mean of 83.50 from the combined grades in the second quarter which is the lowest among the four quarters. However, the results from ANOVA generated a significance of .123 (p≥.05) which means that there is no significant difference between the grades in the first, second, third and fourth quarter
VISIBILITY OF HOSPITALIZED CHILDREN: RIGHT TO LEARNING
No full textThe article results from a research developed in the Postgraduate Program in Health and Development of the Midwest Region, at the Federal University of Mato Grosso do Sul, carried out in the hospital classes of two public hospitals in Campo Grande / MS, between 2014 - 2016. We carried out a bibliographic survey on the topic, allowing us to reflect and discuss the visibility of hospitalized children. We verify how the children's learning process takes place in the hospital environment. The right to basic education belongs to all children, including those who are away from school due to illness. It is necessary to think about the locus of pediatric hospitals in order to develop activities in which the hospitalized child feels productive, in development, and with activities similar to other children of his age. The child must participate in activities that allow him to live on equal terms with other children and have the opportunity to be included in the knowledge acquisition process. Ceccim et al. (1997) affirm that the hospitalized child cannot be doubly penalized: to be sick and to be away from school, friends, games and organizations of space and time. Education is a right for all and a duty of the State and the family and is expressed as a right to learning and schooling. These rights are consolidated in article 214 of the Federal Constitution when expressing that the actions of Public Policies should lead to the universalization of specialized school attendance and in the Law of Guidelines and Bases of National Education in art. 5, by ensuring that the Public Power will create alternative forms of access to different levels of education. This service is characterized as Special Education for serving children considered to have special educational needs as a result of having curricular difficulties due to conditions of specific health limitations recovering the child in an inclusion process offering learning conditions
Ecological panels as an alternative for waste from mechanical processing of Amazonian species
No full textThe wood residues resulting from the operational phases in companies in the forestry market are normally considered by-products and, therefore, are discarded or reused for energy production, however, this material has a greater potential, such as the generation of new products through agglutination, which may generate a new segment in the wood industry, causing competition between products of native and planted species. This research aimed to develop agglomerated panels using residues of two tree species from the Amazon (Dinizia excelsa Ducke and Manilkara huberi (Ducke) Chevalier) and a mixture of commercial Amazonian species of high density, with the purpose of greater added value and a possible solution to reduce the negative environmental impacts of carbon emissions. The experimental design consisted of three treatments with five repetitions in each. Experimental panels were produced with a nominal density of 0.80 g/cm³, using castor oil-based resin with 10% percentages. The panels were pressed with a pressure of 10 MPa, temperature of 100ºC and with a pressing time of 10 minutes. The evaluations of the results obtained were compared with the ANSI A208.1 / 2009 standard and with the literature on agglomerated panels of tropical species. In physical properties, the panels showed compliance with the values found in the literature, however, they are outside the standard of the norm. Regarding the mechanical properties, the MOR values classify the panels in the medium to high density standard in accordance with the standard. The results of the MOE are superior to those of the existing literature, with emphasis on the perpendicular traction that presents values consistent with the literature. The machining evaluations carried out according to ASTM D 1666-11 / 2011, show a good quality in the finish. In general analysis and in compliance with the regulations, all panels have economic viability and potential for industrialization

Epidemiological and sociodemographic characterization of women and men with cancer in a State in the Brazilian Amazon
No full textObjective: Objective: Analyzes the epidemiological and sociodemographic characterization of women and men with cancer in the State of Rondônia, Western Amazon (Brazil), diagnosed over a period of 2 (two) years. Materials and Methods: It is a documentary, cross-sectional and descriptive study, with the systematization of primary data, according to the methodological model recommended by Paraguassú-Chaves et al [25]. We used an instrument developde by Paraguassu-Chaves et al [26], semi-structured, divided into two blocks: (a) Block I – sociodemographic profile and (b) Block II – epidemiological profile. The Ethics Committee on Human Research at the reference hospital was asked to waive the Informed Consent Form. The research project is in accordance with Resolution 196/96 of the National Health Council of Brazil. Results: Of the 3.333 new cases of cancer, 53.4% were female and 46.5% male. The 10 (ten) most common types of cancer among men and women in Rondônia over a 2-year period were non-melanoma skin (C44), breast (C50), prostate (C61), cervix (C53), stomach (C16), thyroid gland (C73), bronchi and lungs (C33-C34), colon (C18), reticuloendothelial hematopoietic system (C42) and rectal cancer (C20). An age range of 50 to 69 years was predominant in both sexes and patients with low educational level. The highest frequency was for married patients. There was a predominance of brown skin, patients born in the State of Rondônia (22.6%) and agricultural workers. The Unified Health System - SUS was responsible for the entry for treatment of 99.5% of patients. Most patients underwent “other isolated therapeutic procedures” and with the disease in advanced stages. Conclusions: The estimate of new cancer cases in Rondônia follows an increasing trend. The scenarios selected from the variables of the sociodemographic and epidemiological indicators of the research require the public health authorities of Rondônia, urgent redirection of actions and strategies for the prevention, control, assistance and treatment of cancer in women and men in Rondônia

No full textThis paper aims to analyze the student dropout from a higher education course, in the city of Guarapari, Espírito Santo, Brazil, through the use of the computational tool known as data mining. The objective was to investigate the possible scenarios for the early identification of students with higher risk of dropping out by analyzing socioeconomic data from business school graduates between 2014 and 2018 with the use of information extracted from the academic system. The methodology used was the experimental research, from a quantitative approach through a comparative analysis of data resulting from the processing of computational algorithms. After the analysis, it was concluded that computational techniques can be used to help administrators to plan pedagogical and administrative actions and that the combination of socioeconomic data with school performance information, using the tool, can yield advantageous results, allowing the fight against evasion to be seen as an early and continuous practice
Personal Financial Literacy among University Students studying Engineering
No full textNowadays financial literacy is essential as in a society much of the financial responsibility has shifted from governments to the individual. The findings of earlier studies show that university students are not knowledgeable about personal finance and their financial skills needs improvement. This study analyzed the survey results of 536 university students to assess the financial literacy, the impact of educational and demo-graphical characteristics to the participants' financial literacy, and the students' financial opinions and choices. Results of regression analyze showed that statistically significant impact to the financial literacy had factors: academic discipline, level of education, gender, nationality, age and the choices to have a current account, a debit card, and investment services. Students studied in the Faculty of Civil Engineering compared to others, had higher knowledge in finance, especially female students.
These results of study give the direction for future research and enable to enhance financial education.
Changes in Soil Acidity Attributes in Areas of Municipal Organic Waste Composting, Santa Catarina, Brazil
No full textComposting is an alternative for treating and recycling municipal solid waste. Composting directly on the soil changes the attributes related to soil acidity. The study aimed to evaluate the influence of municipal solid waste composting in a small scale system on the attributes related to the acidity of soils used for making compost piles. Soil samples were collected at depths of 0-5, 5-10, 10-20, 20-30 and 30-40 cm in four areas under composting (1C, 2C, 3C and 4C) and four adjacent reference areas with no history of composting (1R, 2R, 3R and 4R). The soil was submitted to evaluation of pH in water, total organic carbon (TOC), potential acidity (H+Al), aluminum saturation and base saturation. We found the composting in a small scale system with piles directly on the soil promoted the increase of soil pH values, TOC contents and base saturation up to 40 cm, regardless of the time of use. This shows the potential of the leachate to reduce acidity and aluminum saturation in the subsoil
