No treinamento de estudantes universitários, o efeito do uso do software Matlab no desempenho acadêmico foi avaliado em um grupo de estudantes repetitivos de matemática básica, uma pesquisa quase-experimental, quantitativa com um projeto de pesquisa pré-experimental de pré-teste - pós-teste com um único grupo; Uma amostra de 48 alunos repetidos distribuídos em um único grupo foi utilizada para avaliar o desempenho acadêmico individual em uma escala de 0 a 20; conclui-se que o uso do software matemático Matlab tem uma influência positiva no desempenho acadêmico de um grupo de alunos repetidos

The purpose of this research was to determine the effectivity of applying artificial vision on patterns recognition for the fruits classification in agrobusiness, for this purpose we has used a database with 50 records of 6 fruit varieties with 4 characteristics that are considered for each fruit and a sample of 20 fruits, likewise has been used the automatic pattern recognition technique through the Bayesian classifier implemented in Octave, in the experiment it was recognized to the fruits up to 93.33% and erring in other cases 6.67%. Concluding that is effective to apply artificial vision in the pattern recognition classify fruits.

If once when you were a child, you climbed a ladder and fell, this episode probably put off any interest in trying as an infant in your life. You may have thought in your mind that the stairs were too high or short, big or ugly, and even bad. In materialistic terms it can be argued that all these series of characteristics associated with the ladder are thought from a subjective level, an idealistic and emotional notion that is engrossed in what feels like fear due to trauma. In contrast, a more objectivist vision would have to accept that the stairs are inanimate beings, useful objects for knowledge, but that they do not intentionally participate in the subject's sensitive experience. This last analysis is based on a philosophical trend called realism.

The government on duty assesses the need for scientific productions in its most complex state sector, education. In this line, it is encouraging incentives for academic research, especially in public universities nationwide, after having cleared with a licensing process all universities in Peru. One of the indispensable prerogatives is the publication of articles in indexed journals, having published books, having developed full papers in scientific events, leading research projects among other conditions as a requirement to be immersed as research teachers.

O objetivo da pesquisa era determinar a caracterização e as oportunidades de melhoria dos resíduos sólidos na instituição de ensino. A pesquisa foi não-experimental, com um desenho transversal e descritivo. A população e a amostra consistiu nos resíduos gerados pelos estudantes, pessoal docente e administrativo da instituição educacional San José, no distrito de La Esperanza, província de Trujillo, região de La Libertad, que representa um total de 1551 pessoas. A medição e caracterização dos resíduos foi realizada levando em conta o guia para a caracterização dos resíduos sólidos domésticos, formulado por Kunitoshi Sakurai (1982).  As oportunidades de melhoria foram elaboradas através de um grupo de foco e armazenamento de cérebros com a participação de membros da comunidade educacional e depois mostradas através de uma matriz de dupla entrada. A caracterização dos resíduos sólidos foi determinada e foram estabelecidas oportunidades de melhoria para contribuir para a gestão adequada dos resíduos sólidos na escola "San José, La Esperanza - La Libertad region". Os resíduos sólidos foram caracterizados, com a maior porcentagem de resíduos sólidos sendo papel com 25,56%, plástico com 16,33% e resíduos de frutas com 15,69%, enquanto a menor porcentagem de resíduos foi de metal com 2,08%, papelão com 5,26% e madeira com 5,26%. A produção per capita mostra que cada pessoa pode gerar 65 gramas de resíduos sólidos para cada membro da comunidade educacional. Foi elaborada uma matriz que mostra as oportunidades de melhoria a fim de reduzir e gerenciar adequadamente os resíduos sólidos gerados na instituição de ensino, La Esperanza - La Libertad, destacando a política de gestão ambiental, a implementação de uma usina de compostagem, um programa de treinamento e uma reciclagem, para os quais foram determinadas responsabilidades e tempos estabelecidos.

The cultivation of the potato is a food of the first order in the human diet that for its cultivation a series of factors intervene such as soil and water, especially the latter of vital importance, for which there is even a worldwide mentioned phrase "without water there is no life ”, so it is necessary to dose the amount of water that the crop needs for its development and normal performance, in order to do so, it was proposed to carry out the present research work in order to determine the total water demand for this culture. The work was carried out in the fields of the training demonstration center of the “La huaycha” irrigation project in the Orcotuna district of the Concepción province, Junín department - Peru, in two agricultural campaigns. The main objective was to determine the coefficients of consumptive use (Kc) for the cultivation of potatoes in conditions of the Mantaro valley for a better management of irrigation water.

Este artigo mostra uma comparação de casos confirmados e mortes por Coronavirus (COVID-19) entre países sul-americanos, considerando casos por milhão de habitantes e padronizando o tempo de infecção a partir do dia da confirmação do caso zero para cada país. O objetivo é avaliar a propagação deste vírus de uma maneira mais uniforme e assim avaliar o resultado das medidas tomadas pelos governos contra a COVID-19, já que vários centros de pesquisa mostram comparações sem levar em conta a proporção de habitantes, nem o tempo (dias) de infecção entre países. Além disso, fornecemos previsões de curto prazo e uma estimativa do fim dos casos confirmados nos países mais afetados.

The present research work was carried out with the objective of determining the influence of interactive strategies on the understanding of philosophical readings of university students from San Cristóbal de Huamanga, Ayacucho. To this end, we are guided by the positivist paradigm and its quantitative approach in quasi-experimental design. The study area was made up of university students. The sample consisted of 30 students from the Professional School of Obstetrics that made up the experimental group and 30 students from the Professional School of Nursing that made up the control group, both groups from the Faculty of Health Sciences. To compare the qualifications of the groups, a comprehension test of philosophical readings was applied. To test the hypothesis, the Wilcoxon statistical test was used. The results of the investigation determined that 70.0% of the students in the experimental group, with the application of interactive strategies, were within the good average and 30.0% were within the excellent average compared to the control group that did not reach these averages. . In conclusion, with a confidence level of 95% and a significance level of 5%, when obtaining a p value <0.05 (0.000), it is stated that the application of interactive strategies significantly influence the understanding of philosophical readings of the University students from the National University of San Cristóbal de Huamanga, Ayacucho-Peru.

The objective was to establish the relationship between school violence and the levels of learning achievement of students in the fifth cycle of a public educational institution in Puerto Maldonado. The research approach was quantitative, the design non-experimental and the relational level. The data collection instruments were the AVE Test and the Consolidated Assessment Certificate. The results indicate that there is an inverse and significant relationship between school violence and levels of learning achievement (rs = -0.297; p = 0.021 <0.05). It was concluded that high levels of school violence are related to low levels of learning achievement.

Through this text, you can see antithetical opinions of the term leisure or its equivalents that have implications in knowledge, daily life, science and philosophy. The two senses that the term leisure has had over time are the negative and the positive. It is summarized, on the one hand, the negative sense given by ordinary people, Hesiod, Seneca, Michel de Montaigne, Francis Bacon, Immanuel Kant and Frederick W. Taylor, while, on the other hand, you can estimate the positive sense of the concept in Plato, Aristotle and Cicero.
