In the Cuban educational field, it is understood that, in order to advance in the educational research paradigm, teachers must be aware of the advances that occur in current pedagogical sciences, with the intention of being able to provide efficient and effective responses to the demands of learners with special educational needs. The objective of this work is to reflect critically on some relevant aspects that intervene in the preparation of teachers to educate and stimulate the socialization of students with Autism Spectrum Disorder in conditions of educational inclusion. This work can contribute to enrich the discussions that take place in contemporary educational sciences and, therefore, can serve as support and information for those who make political decisions in inclusive educational contexts, especially for teachers with social responsibility. educate and socialize students with autism spectrum disorders.

The article Remote teaching: theoretical approach to teacher training and practice aims to reflect: on the formation and construction of teaching at the university, on the importance of theoretical and practical knowledge, on the need for this construction to have the school routine as a reference locus and contextualize remote teaching as a teaching methodology in times of pandemic. The reflection on remote teaching is important in the training process since contemporary education requires new and different skills from this education professional in addition to the skills required in the classroom environment. For the idea of ​​this writing, the terms remote education, distance education, online education and virtual education are considered as similar since they are expressions used in the teaching model that has been structured in public education policies. Training in undergraduate courses undertaken so far does not include training teachers for virtual, online, remote education. In addition, training can be questioned, since training difficulties are not defined only in the appropriation of technologies for remote teaching, but in reflecting and developing new strategies to minimize the negative impacts on learning in the virtual environment.

The purpose of this work is to carry out a theoretical and reflective essay on relevant issues in the current world pandemic situation regarding the role of inclusive education and of educational centers around social justice, showing the importance of the real involvement of families as the axis of the educational triangle: inclusive education-family-school. One of the pillars of inclusive education is removing barriers to learning and participation for all and helping to establish the change to work on in later moments. Currently, we can verify that the pandemic has sharpened the gap between social groups, making families more vulnerable in relation to the education of their children, forced to carry out educational tasks in the family environment. So we consider the situation facing education at this time without exclusions.

In the development of this work, we will begin with the investigation of information on macro-skills, citing sources from different authors with their opinions on said topic and in the last part an innovative pedagogical proposal will be made developing said topic in an ELE classroom with the completion of a project. After carrying out this search, we have concluded that technologies act in a favorable way in the teaching-learning process of students studying a foreign language. The purpose is to know the importance of macro skills in the achievement of Spanish as a foreign language. Therefore, it will be carried out with a practical proposal that is the innovation project in which the students achieve significant learning through motivation. Also highlight the importance of knowing the Spanish culture for learning its language.

The main objective of this article is to make the teacher of Spanish as a Foreign Language (ELE) see that macro-skills or linguistic abilities must be integrated and developed in the classroom.To do this, key concepts are based first, such as macro skills or linguistic skills, to then do a theoretical search based on various authors on oral and written comprehension and expression.This article is due to the relevance of communication throughout the world. Oral and written communication are unquestionable paths in our lives that allow us to communicate with the outside world. That is why one of the objectives of this article is to provide useful tools for ELE students, so that they find themselves with a communication deficit.

In this work, a novel stack of well-known technologies is presented to determine an automatic method to segment the heart sounds in a phonocardiogram (PCG). We will show a deep recurrent neural network (DRNN) capable of segmenting a PCG into their main components and a very specific way of extracting instantaneous frequency that will play an important role in the training and testing of the proposed model. More specifically, it involves an Long Short-Term Memory (LSTM) neural network accompanied by the Fourier Synchrosqueezed Transform (FSST) used to extract instantaneous time-frequency features from a PCG. The present approach was tested on heart sound signals longer than 5 seconds and shorter than 35 seconds from freely-available databases. This approach proved that, with a relatively small architecture, a small set of data and the right features, this method achieved an almost state-of-the-art performance, showing an average sensitivity of 89.5%, an average positive predictive value of 89.3% and an average accuracy of 91.3%.

Optical immunoassays require measurement systems capable of distinguishing the light from the laser source, used to illuminate the assay, from the light generated by the particles contained within the assay itself (fluorescence). The main challenge is that the light used to excite the sample is several orders of magnitude more intense than that generated by fluorescence. Usually, single junction photodiodes and optical filters are used. The sensitivity of these schemes is limited by the filter performance. In this work, the design of a CMOS integrated circuit including buried double junction photodiodes (BDJ) is presented. This approach allows the measurement of both light sources simultaneously. From simulations, it is shown that this integrated circuit with BDJ would achieve a better detection limit than the scheme based on single-junction photodiodes of equivalent silicon area.  Furthermore, integrating the photodetectors and the reading circuit on the same chip would make the system suitable to be used in biomedical applications such as Point-of-Care (POC) devices.

In this work we present the study, development and characterization of a cylindrical focused ultrasonic sensor based on a piezoelectric polymeric material. For the design and implementation of the transducer, we carried out simulations using the commercial tool k-Wave and we used a construction method with great repeatability and low cost. For the characterization of the detection system (sensor + amplifier), we made electrical and acoustic measurements that allowed to determine its sensitivity and equivalent pressure noise. The results of this work show that the implemented sensor is suitable for optoacoustic tomography.

A method for high power pulse transformer design is presented based on analytical assumptions that lead to sizing equations allowing one step design which may then be improved by iteration. An example of a transformer design procedure used in a pulse generator for electroporation is included.

The global market for smart parking solutions is booming. Nowadays, this market is highly competitive due mainly to the increase in car ownership and the number of vehicles circulating the roads. However, there is a technological gap between Argentina and other countries. This work presents the Automated LPR Parking System for Argentinian Plates SAE (in Spanish, Sistema Automatizado de Estacionamiento) designed and developed in its prototype version for a private company, to control and manage the entry, stay and exit of vehicles in parking lots. The system is composed by two main modules: the automatic license plate recognition system and the Principal System Board. This board allows the connection of the central unit with peripherals such as magnetic field sensors, access barriers and infrared barriers. In addition, the system manages a database that stores the necessary information for the parking management. Registered users that pay monthly and ocasinal users are considered. Furthermore, the system implements a mechanism for vehicle size detection to determine the value of the parking fees. SAE handles both hardware and system failures and exceptional situations. In addition, the entry and exit of vehicles are handled simultaneously.
