En la actividad hospitalaria tal y como se indica en el artículo “Aspectos médicos-legales de la historia clínica” (Rio, 1999), las historias clínicas son un elemento muy importante en la asistencia médica de un individuo, así también en lo concerniente a la medicina de forma colectiva o institucional; y debe encontrase regulada bajo estándares de calidad óptimas para preservar el derecho a la salud del paciente, así como el derecho a la privacidad. También se menciona la disciplina que recae sobre los tratantes (médicos/as, enfermeros/as, otros), para no caer en incumplimientos. Otro punto importante tiene que ver con lo que contienen los historiales médicos en cuando la exploración personal, pruebas diagnósticas primarias o complementarias, juicios sobre los diagnósticos y tratamientos, así como los detalles sobre la evolución de los pacientes. Por mucho tiempo se...

The study of Neuroscience and The seven Learnings introduce Neuroscience as the new paradigm that enables to analyze and explain the intelligent human behavior. The discoveries found in this field have been shown not only in the theory but in the pedagogical practice as well. In the first case, one of the most recent theories about intelligent behavior has been conceived from the perspective of neuroscience (science that studies HUMAN BRAIN). (Beauport and Diaz, 1994) This study has given more relevance to the relation between the function of the brain and human behavior as well as the conditions that lead to an efficient teaching – learning process. In this context, we introduce The seven Learnings, described by Edgar Morin that state central problems which have been ignored and that are necessary in order to reach a successful teachinglearning process in this century. These seven Lea...

There is a theoretical need for the pedagogical analysis, the presence and use of the New Information and Communication Technologies in the educational processes, this article proposes to recognize, from a sociocultural perspective, the Virtual Environments of Learning as an instrument of mediation. This means, as a component adding to the educational activity two orientations: as structure of external action and as a source for internal representation. Formulated in this way, a virtual learning environment orients itself towards proper ways of technological performance in the educational process. Simultaneously this triggers in students, new forms of cognitive regulation that offer new opportunities and strategies as a condition of learning. This perspective is part of the pedagogic dimension necessary for a pertinent application and orientation of learning in virtual trainning.

In the present study, the collection of machine learning algorithms of the Weka program was used to predict the bubble pressure of 36 oil samples, determining the accuracy of their results with the 10-fold cross-validation test method. Subsequently, for comparison purposes, the bubble pressures were calculated with the correlation generated in the work from which the samples were taken and their results were more precise than those obtained by the algorithms in 4 of the 7 performance metrics used. Due to this situation, and considering that the correlation was evaluated with the same data with which it was generated, the test method was changed to validation with the training data and the bubble pressures were predicted again. Other things being equal, machine learning was more accurate than correlation on all performance metrics.

In this research, the objective was to describe the perceptions that university students manifest of their formative process when moving from a face-to-face modality to a virtual one in the time of the SARS-CoV2 pandemic. The object of study was constructed from a sociological perspective that associated objective conditions and the corresponding production of subjectivities. Methodologically, three moments were recovered: 1) determination of social and technological capital; 2) construction of social classes from the determination of the volume and structure of capital; and 3) detection of student perceptions. The results (Cronbach's alpha of 0.913) establish that the lower the volume and structure of the students, the lower the academic performance, the less proclivity to an online work, the greater the need for academic accompaniment and the lower the institutional follow-up. By way o...

The 21st century requires people to make good decisions based on thoughtful and reasoned thinking. It is the task of the university teacher to provide the necessary conditions to develop critical thinking by using strategies that place the student as the basis of teaching work. The objective of the research was to determine the relationship between the level of critical thinking and the level of learning of mathematics of students entering university. The research is based on the quantitative correlational scope approach with transectional, correlational design. The sample was 115 students belonging to two universities, one private and the other public, located in Lima, Peru. For data collection, two tests were administered: one to assess the level of critical thinking, and the other to assess the level of learning in mathematics. The results show that critical thinking and learning of m...

The main objective of this research is to deepen our understanding of the concept of cooperative interaction under conditions of asynchronous mediation in virtual learning. The study starts with the basic assumption that technology is not a neutral component in an interaction (Person–Machine–Person). It follows; therefore, that a change in the way of perceiving interaction may be created by the way manoeuvrability is facilitated via the internet and the framework of virtuality. The research methodology examines the cooperative asynchronous interaction as two different but complementary processes. The initial, theoretical exploration is designed to understand the psychological, pedagogical and technological factors under which cooperation in virtual learning is generated. The subsequent, empirical exploration is designed to observe –via a triangulation of the data– how the coopera...

In the process of educational inclusion, various ways have been tried to take advantage of the conditions in which basic education is developed, allowing the student with disabilities to learn with quality. Therefore, the purpose is to describe the design of strategies in inclusive education to improve the learning process in regular classrooms in the Peruvian Amazon. It is the product of a non-experimental descriptive study, with a sample of 183 teachers. It was found that the teachers of the regular institutions consider the use of basic techniques for the social development of the included child deficient, little use of multiple intelligences and active participation. For their part, teachers in inclusive classrooms indicate that techniques for resolving conflicts and decision-making techniques have not been incorporated. The teachers of the special center consider that importance has...
