Cvrriculum program: benefits and challenges of embedding virtual reality as an educational medium in undergraduate curricula
Get PDFSince the release of more affordable, portable, and easy-to-use virtual reality (VR) systems in 2014, there has been renewed interest in using this technology in education, as an alternative to traditional learning, because it creates more opportunities for experiential education. Despite the many benefits and affordances of VR, widespread adoption in post-secondary education has been limited, and gaps remain in the provisioning of detailed guidelines for implementing this technology in curricula. Our team developed the CVRRICULUM (CVR) initiative: a pilot program that recruited instructors to adapt a traditional written assignment into a VR format. A mixed-methods approach was used to collect data from five instructor and 18 student participants. In this manuscript we describe the implementation process, report the identified challenges, and provide suggestions that should improve subsequent offerings. Our team addressed raised challenges by creating a set of resources available on the CVR website
Ozonized and natural compounds for in vitro Acinetobacter Baumannii treatment
Get PDFAcinetobacter baumannii stands out as an opportunistic pathogen responsible for Healthcare-Related Infections. This study aimed to evaluate the efficacy of natural oils in natura and ozonated on A. baumannii mortality. The randomized experiment used the A. baumannii strain and natural oils (palm, canola, and coconut) ozonized and in natura (control group). Minimum inhibitory and bactericidal concentrations and chromatography were employed in the study. Through the ozonized and fresh oils antimicrobial action, the natural oils\u27 effectiveness and the bacteria mortality were evaluated. The data was submitted to the Mann-Whitney and Kruskal-Wallis tests. When comparing the natural oils, ozonized canola oil stood out as the most efficient in destroying the bacteria. The other ozonized oils showed a 90% reduction in the microbial load in the first ten minutes of treatment. For use in natura, palm oil stood out with 85.9% microbial load reduction. According to the results obtained, the antibacterial activity of natural oils is remarkable, showing that they were expressively effective in inhibiting the A. baumannii growth, presenting themselves as a new adjuvant therapy antibacterial drug. The study concluded that the ozonized oils are more efficient in both MIC and MBC when compared between the ozonized and the untreated groups. The bacteria are sensitive to the ozonized oils

From the results obtained, it is accepted that these activities are divided into synchronous and asynchronous rooms, and that is still in the adaptation phase; also through the experience report suggested to improve communication, the increase in feedback from teachers to students of activities and from students to management on the development of APNPs and difficulties encountered, to promote their effective improvement
Perception index of environmental education in fundamental education schools in a city on the Brazil / Bolivia frontier
Get PDFObjective: to analyze the Environmental Education Perception Index in the light of national curricular parameters (PCN’s) within the scope of elementary education in state schools in the city of Guajará-Mirim, Rondônia, on the Brazil / Bolivia border. Method: for this study, factor analysis was used as a mechanism for building performance indices for each parameter studied. The Statistical Package for the Social Sciences - SPSS [30] tool was used to determine the proposed indexes that followed the scale advocated by Hair et al [21]. Results: the results presented by the teachers of the 4 schools correspond to the perception index considered “good” with an average index of 0.699. The average perception index of school technicians and managers was 0.591, considered a “regular” index. The students had an average performance of 0.537, considered a “regular” performance index. The general IPEA among all schools surveyed was considered “regular” with a performance index of 0.597. Conclusion: the fact that Guajará-Mirim has 92% of its territory occupied by Conservation Units and Indigenous Lands and a strong environmental policy does not correspond to the level of abstraction applied by formal Environmental Education. Environmental Education given in Guajará-Mirim elementary schools imposes considerable risks on the environmental conscience of future generations, as it presents certain deficiencies in fulfilling its institutional role as a social transformer, configuring itself as a limiter of sustainable development and awareness environmental
The Use of Open-Ended Student Worksheet to Improve Mathematics Communication Skills in Algebra
Get PDFCommunication is the foundation of every learning activity. Mathematical communication is a skill to represent ideas in mathematical language so that it is understood by others who are used in problem-solving activities. This study aims to improve mathematical communication skills by using open-ended student worksheets in algebra. The research sample involved 6 junior high schools in Purworejo Regency, Indonesia which is divided into 2 groups, the experimental group consists of 91 students and the control group consists of 96 students. The study design used a randomized static group comparison design. The research instrument used 5 item essay tests that contained non-routine problems. The data analysis technique used an independent sample T-test. The results showed that the communication skills of students who were subjected to learning using open-ended student worksheets were better than the communication skills of students who were subjected to learning using student worksheets that are commonly used by teachers. These results provide an important impact that teachers should always integrate the presentation of non-routine problems in the form of worksheets as an integral part of mathematics learning

Violence, trafficking and drug use in public schools in Belém -Pará - Brazil
Get PDFThe research shows how violence, trafficking and drug use has been recurrent within schools, causing directions that are difficult to contour by Brazilian government officials. The research had a qualitative and quantitative character. The method used was interviews with teachers and the use of questionnaires with a group of one hundred and seventy students and sixteen teachers. Among all the problems, misery; the use of drugs; the arrival of adolescence; the insertion of the researched group in risk areas belonging to Perverse Territorialization; the lack of definition of a full and adequate curriculum for our social problems; the lack of adequate punishment; the influence of family habitus has contributed to the spread of violence, stimulating parallel activities with the predominance of drug trafficking and organized crime where it presents a growing approximation with the local community in need of all types of services and improvements not provided by the State, causing the increase in all crime rates, the increase in drug trafficking as well as the increase in cases of psychological disorders. Among these reasons, violence in the school environment has increased. The actions necessary to reduce school violence are pointed out in this article, knowing that for its consolidation, the support of the school community and the creation of internal codes of conduct essential to living in the school environment are necessary

Artificial neural networks for predicting the generation of acetaldehyde in pet resin in the process of injection of plastic packages
Get PDFThe industrial production of preforms for the manufacture of PET bottles, during the plastic injection process, is essential to regulate the drying temperature of the PET resin, to control the generation of Acetaldehyde (ACH), which alters the flavor of carbonated or non-carbonated drinks, giving the drink a citrus flavor and putting in doubt the quality of packaged products. In this work, an Artificial Neural Network (ANN) of the Backpropagation type (Cascadeforwardnet) is specified to support the decision-making process in controlling the ideal drying temperature of the PET resin, allowing specialists to make the necessary temperature regulation decisions for the best performance by decreasing ACH levels. The materials and methods were applied according to the manufacturer\u27s characteristics on the moisture in the PET resin grain, which may contain between 50 ppm and 100 ppm of ACH. Data were collected for the method analysis, according to temperatures and residence times used in the blow injection process in the manufacture of the bottle preform, the generation of ACH from the PET bottle after solid post-condensation stage reached residual ACH levels below (3-4) ppm, according to the desired specification, reaching levels below 1 ppm. The results found through the Computational Intelligence (IC) techniques applied by the ANNs, where they allowed the prediction of the ACH levels generated in the plastic injection process of the bottle packaging preform, allowing an effective management of the parameters of production, assisting in strategic decision making regarding the use of temperature control during the drying process of PET resin
The Brazilian Economy in the 1980s: The Lost Decade or wins? The consequences of the external debt crisis, inflation and the state crisis
Get PDFKnown as a lost decade, the 1980s marked several events in Brazil and other Latin American countries. Such events had a profound impact not only on the economy but also on Brazilian democracy. The Brazilian economy in the 1980s went through one of the most serious crises in its history, which resulted in the stagnation of gross domestic product and unprecedented inflation rates. Despite this critical economic situation, social indicators showed positive evolution. It was shown that, although Brazilian families adopted as a strategy to face this crisis the overuse of family work force in the labor market, the evolution of income and poverty in this period was unfavorable
