Introduction/purpose: All data exchanged over the Internet as well as other computer networks should be considered exposed to various types of security threats. In light of this, the transmission of voice over applications that do not use any type of crypto-protection allows anyone to discern the content of communication. Since voice transmission requires as little delay as possible, various protocols are used to enable crypto protected real-time communication. This paper presents one solution in a desktop application variant. Methods: The essence in voice exchange systems as well as in other systems where real-time communication is necessary is the establishment of a crypto-protected session which is a virtual secure channel for communication to which only the communicating parties have access. Voice sessions in the application are established with the SIP (Session Initiation Protocol) protocol. The sessions are further protected using the ZRTP (Zimmerman Real-time Transport Protocol) protocol. FusionPBX was used as the SIP server (registrar) for testing purpouses. The application is developed in C++ language using the Qt framework. Results: The final version of the application demostrates that ZRTP and SIP protocols are well suited for establishing crypto protected voice communications with low delay. Conclusion: This solution provides cryptographic functions for data secrecy and the management of cryptographic keys. Improving the solution with digital signatures and certificates will result in additional cryptographic functions: data integrity and personal identification. With this improvement, this solution will be able to withstand modern security threats with low delay [ABSTRACT FROM AUTHOR]

editorial ,comunicaciones ,Communication. Mass media ,P87-96 - Abstract
La agenda de investigación de las comunicaciones es probablemente una de las más desafiadas por los vertiginosos cambios del espacio mediático, especialmente en el campo digital, en el que las nuevas interacciones y agencias ocurren en el marco de la globalización tecnológica y de la economía de la información algorítmica. En camino al fenómeno de lo que Casilli y Posada (2019) denominan la plataformización del trabajo y de la sociedad, con resultados aún inciertos, en octubre de 2022 se efectuó la compra de Twitter por 44.000 millones de dólares (Conger & Hirsch, 2022). Hasta entonces, esta plataforma de microblogging de acceso abierto era usada en gran medida como un instrumento de información esencial por distintos medios y, como afirma Vergeer (2015), era un recurso relevante de comunicación política.

Access to information is a right that should not be limited because of being a member of a linguistic minority. The Deaf Community, which has its own language and culture, faces limitations in access to the media, such as open-signal television, unlike hearing people. This phenomenon was investigated from the point of view of people from the Deaf Community in order to be able to raise coherent proposals to meet their needs. The objective was to know the perception of members of the Peruvian Deaf Community about the interpretation in Peruvian Sign Language (PSL) in open signal television channels in Peru. It was a qualitative study of phenomenological design in which a group of people representing the Deaf Community of Lima, Peru participated. Group interviews were conducted with the presence of an interpreter known by all the interviewees. The results show that the Deaf Community interviewed perceives that there are deficiencies in terms of the number of interpreters and the space assigned to them on screen. The people interviewed stated that the Deaf Community experiences a feeling of isolation and mockery due to the small number of programs that are interpreted and the appointment of interpreters who do not adequately convey the information. In addition, they consider that there is a need for better training of interpreters in aspects such as linguistic diversity and the use of classifiers and spacing. Based on the findings and their interpretation, the researchers make some final considerations to promote good practices aimed at reducing the gap in access to information for the Deaf Community in Lima, based on inclusion and equity.

This article examines how people gathered and transmitted political information in Colombia during the second half of the nineteenth century. Existing scholarship has predominantly focused on the study of the press in Colombia and Latin America. However, few historians have explored other forms of information, such as telegrams, rumours and letters, or how Colombians combined these. By focusing on how various forms of information circulated through political, familial and commercial networks, this study offers a new dimension to our understanding of communications in Colombia. It argues that this was a period of increasing circulation of information due to social, political and economic change, as well as new links between oral and written practices. Thus, this article illuminates how Colombians circulated political information in a society of restricted literacy in post-colonial Latin America, offering new insights into politics, communications and the interplay between written and oral culture.

Esta investigación implementa el uso de herramientas computacionales para el Sistema Información Geográfica “SIG” por medio de “ArcGIS”. De acuerdo con el Ministerio de las TIC de Colombia, hasta el 2018 aproximadamente el 50% de las regiones de Colombia contaban con conectividad limitada y las poblaciones más vulnerables tenían acceso del 20% al 40% de los servicios TIC (MinTIC, 2018). De esta forma, se hace necesario incrementar el porcentaje de accesibilidad a los servicios TIC en la población, en búsqueda de mejoras en las condiciones de vida. Usando la metodología del análisis espacial y con el objetivo de evaluar e identificar las áreas que presentan la mayor idoneidad para la instalación de sistemas de telecomunicaciones para la transmisión de señales radioeléctricas, se realiza la implementación de herramientas “SIG” por medio de “ArcGIS”. Este estudio se desarrolla sobre el área del municipio de San Antonio del Tequendama en Cundinamarca Colombia como estudio de caso.

El objetivo es precisar la consolidación legal y regulatoria de las comunicaciones en Colombia como servicio público entre los años 1847-2020. La metodología se basa en un enfoque mixto -información primaria y secundaria. Los resultados evidencian que la estructura legal y regulatoria del servicio público de las comunicaciones en Colombia entre los años 1847 y 2020, a pesar de las diferentes ideologías y toma decisiones, responden a la premisa de aprendizaje institucional con alianzas y transferencia de conocimiento técnico por parte de actores internacionales y privados. La conclusión está enmarcada en un sector dinámico y progresivo, que a pesar que se regule como servicio público es muy diverso y complejo por la incidencia de la regulación internacional.

Given the essential role of communications within a space exploration mission, it is important to accurately plan communications systems around the environmental parameters they will meet with on mission location. Mars is the expected goal of many future missions, and as such requires an accurate model of radio propagation within its environment. Extant models with this goal tend to be highly localized. In this study, a global scale GIS model of the Martian communications environment is built using existing raster and vector data implemented in the QGIS program. Overlaying these properties created a map depicting favorable and unfavorable communication conditions across the Martian globe. The global scale and multilayered nature of this depiction can help mission planners understand and prepare for large scale environmental patterns affecting communications on Mars.

This work aims to identify, classify, and categorize relevant activities regarding professional journalistic work in major disaster coverage, and develop a conceptual model that organizes them theoretically. We conducted a series of empirical data collection stages (background gathering through in-depth interviews and content analysis) and later applied the theory-building block approach that uses concepts to create and operationalize constructs. The main result is a six-dimension model based on the traditional questions of the journalistic process: How, why, who, when, what, and where. It comprehensively addresses the multiple aspects involved in disaster coverage: emotional, logistic, professional, and ethical challenges, as well as timing, key actors/roles, and their needs and demands according to the disaster type and stage they face. The model also brings together a group of potential activities journalists must confront and carry out when covering major disasters or highly significant social crises. Its main contribution is to make a useful theoretical tool available to academia and the media, striving for a versatile matrix management approach. [ABSTRACT FROM AUTHOR]

En un mundo globalizado, regido por las tecnologías y comunicaciones, la realidad para la educación física es adversa, pues existe una gran brecha de desigualdad que ha dificultado su reinvención equilibrada e inclusiva en el ámbito virtual, a diferencia de lo ocurrido en otras áreas. Asimismo, en algunas instituciones ha desaparecido, en un momento en el que la mejora de los programas de educación física jugaría un papel importante en la prevención de trastornos mentales, el incremento de la salud física y la resiliencia en estudiantes, como lo afirma la Unesco (2019). También, en el Perú, en colegios con Bachillerato Internacional y particulares de elevado costo, las horas de educación física aumentaron, lo que evidencia el reconocimiento de su importancia para menguar el estrés, la ansiedad y el sedentarismo a mediano y largo plazos. Por tanto, se debe evaluar la situación mundial y peruana abordando el aspecto socioeconómico y la enseñanza de la educación física en el contexto de la pandemia y la globalización.

NUCLEAR energy , *EDUCATIONAL planning , *KNOWLEDGE management , *APPLIED sciences , *INFORMATION sharing - Abstract
Special attention to activities related to the preservation of nuclear knowledge and its transfer to new generations has given the International Atomic Energy Agency. In order to achieve a better nuclear knowledge management within the framework of the national actions foreseen within the regional project RLA 0057, the Cuban Youth Nuclear Network was created. Since its conception, it aims to provide a space for the exchange of knowledge for the dissemination and development of nuclear technologies for peaceful purposes. This work presents an educational strategy designed with the collaboration of the Higher Institute of Technologies and Applied Sciences of the University of Havana and the Agency for Nuclear Energy and Advanced Technologies, whose impact will result in an increase in the participation of young students and professionals in the sector in the promotion and development of nuclear technologies. As part of this strategy, an action plan was executed in the 2019-2020 biennium, the results of which are shown. The strategy described and the actions developed to execute it had a direct impact on the more active participation of young students and professionals in the sector in the promotion and development of nuclear applications. Likewise, the results of the application of the proposed action plan demonstrated the relevance of said strategy to achieve the objectives set by the network. [ABSTRACT FROM AUTHOR]

The article considers the types of needs of the individual in the field of culture and art as a communicative component of modern society, namely, the cultural and aesthetic needs, which are based on the dissemination of social information. Social information in society is the most important condition for maintaining the activities of individual and collective entities at the level of modern requirements, goals and objectives of the individual. In the modern world, the interaction of cultures is the basis of social development and is of paramount importance, occupying a leading place in the value orientations of people. The information space creates a favorable field for the formation of personality, but also becomes an area of actual reality in which targeted influence and management of human interests, needs, beliefs and views are conducted. The basic needs of people in the field of culture and art can be considered as a way classification of their communicative activity. Developed cultural and aesthetic information needs absorb many of the highest human needs: in building a universal picture of the world and knowing those sides and phenomena that most interest a person in self-knowledge, self-education; in discussing the crucial issues of human being; in communication and self-expression in the development of their human forces and abilities.

La seguridad en los sistemas de gestión de Edificios (SGE) es de gran importancia, la falsa creencia de que no es un blanco de interés para hackers, o incluso para usuarios o empleados, puede llevar a ingratas sorpresas, que varían desde una consecuencia incómoda, a un verdadero riesgo empresarial. Se debe proteger tanto de amenazas externas como internas. Los estándares de comunicación de SGE como KNX han comenzado en forma reactiva a implementar niveles de seguridad en sus sistemas. En el trabajo, se propone una metodología que permita implementar medidas para brindar seguridad en las comunicaciones de un SGE automatizado con KNX; y que clasifica las amenazas y los sectores vulnerables, implementa mecanismos para contrarrestar o evitar ataques y describe una arquitectura de red segura. La metodología puede ser utilizada también en SGE basados en otros estándares de comunicación diferentes a KNX.

The content of the 847 papers presented by authors from Spanish universities at the six conferences of the Spanish Association for Communication Research (AE-IC) is analyzed. The six conferences were held in Santiago de Compostela (2008), Malaga (2010), Tarragona (2012), Bilbao (2014), Madrid (2016), and Salamanca (2018). The research variables of study are: author's profiles, geographic location, gender, home university, most commonly studied topics, and considered media. The results confirm that the gender divide no longer exist: in fact, there are more female than male authors. Universidad Complutense de Madrid and Universitat Autònoma de Barcelona exhibit the highest rates of participation, and Madrid and Catalonia are the most active regions, followed by Andalusia and Valencia. The topics treated are quite diverse, with the study of media content standing out, mainly those focused on political communication. Other common topics are the impact of the digital age, and audiovisual media structure. [ABSTRACT FROM AUTHOR]

The set of investigations and operations that under the name Operação Lava Jato (Operation Car Wash) carried out in Brazil in recent years, culminated in the imprisonment of former President Luiz Inácio Lula da Silva. The political situation created, with the impeachment of President Dilma Rouseff, and the appointment of her Vice-President Michel Temer as President, set the stage for the triumph of President Jair Bolsonaro. Based on the assumptions about the systemic code "power-not power", and the autonomy of the powers (Executive, Legislative, Judicial), the objective of this work is to describe and identify these processes in the analysis plane of communications between the political-administrative and legal systems. As conclusions, we formulate the hypothesis about the limited autonomy between the powers and the porous limits between them, as a cause that stops an effective fight against corruption.

- Abstract
The study seeks to identify the discussion topics and establish the sentiment of Twitter texts related to entrepreneurship and entrepreneurs during a crisis period. The data was collected from 163,843 tweets between May and June 2020. A group of popular hashtags about entrepreneurship and business was identified. The extensive data process was carried out using the term association technique and text sentiment analysis. The results indicate that crisis communications in businesses and by entrepreneurs had two objectives, to communicate the crisis inside the business due to the pandemic and communicate the elements of crisis solution by highlighting the skills, knowledge, means, and critical issues to overcome. The study contributes to the situational crisis communication literature by understanding the characteristics of crisis communication during a crisis period in popular entrepreneurship hashtags., El estudio busca identificar los temas de discusión y establecer el sentimiento de los textos en las comunicaciones de crisis de Twitter relacionadas con el emprendimiento y los emprendedores durante períodos de crisis. Los datos se recopilaron de 163.843tuits entre mayo y junio de 2020. Se identificó un grupo de hashtags populares sobre emprendimiento y negocios. El proceso de big data se llevó a cabo utilizando la técnica de asociación de términos y análisis de sentimiento de texto. Los resultados indicanque la comunicación de crisis realizada en las empresas y por los empresarios tuvo dos objetivos, comunicar la crisis al interior de las empresas por la pandemia y comunicar los elementos de solución de crisis mencionando las habilidades, conocimientos, mediosy cuestiones necesarias a superar. El estudio contribuye a la literatura de comunicación de crisis situacional con el conocimiento de las características de la comunicación de crisis durante periodos de crisis en los hashtags de emprendimiento popular.

- Abstract
In this era, where overproduction is a common reality in developed countries, Internet of Things (IoT) devices are no exception to this trend. Their low price and high-speed manufacturing make them even more disposable when they run out of battery. As a result, they are often left in their original location without a second thought. The main purpose of this project is to localize these devices by utilizing the old signals they sent to their re- spective concentrators. The techniques employed throughout the study must consider external factors, such as noise and environmental effects. Obtaining these positions can contribute to enhancing reuse and recycling efforts., En la época actual, donde la sobreproducción es una realidad común en los países desarrollados, los dispositivos de Internet de las cosas (IoT) no son una excepción a esta tendencia. Su bajo precio y su alta velocidad de fabricación los hacen aún más desechables cuando se quedan sin batería. Como resultado, a menudo se dejan en su ubicación original sin pensárselo dos veces. El objetivo principal de este proyecto es localizar estos dispositivos utilizando las señales antiguas que enviaban a sus respectivos concentradores. Las técnicas utilizadas a lo largo del estudio deben tener en cuenta factores externos, como el ruido y los efectos ambientales. La obtención de estas posiciones puede contribuir a mejorar los esfuerzos de reutilización y reciclaje., En l'època actual, on la sobreproducció és una realitat comuna als països desenvolupats, els dispositius d'Internet de les coses (IoT) no són una excepció a aquesta tendència. El seu baix preu i la seva alta velocitat de fabricació els fan encara més d'un sol ús quan es queden sense bateria. Com a resultat, sovint es deixen a la seva ubicació original sense pensar-s'ho dues vegades. L'objectiu principal d'aquest projecte és localitzar aquests dispositius utilitzant els senyals antics que enviaven als seus respectius concentradors. Les tècniques emprades al llarg de l'estudi han de tenir en compte factors externs, com ara el soroll i els efectes ambientals. L'obtenció d'aquestes posicions pot contribuir a millorar els esforços de reutilització i reciclatge.

[Resumen] En este artículo se presenta el modelado y control de un robot de dos grados de libertad mediante diferentes metodologías como el regulador Proporcional-Integral-Derivativo (PID) y la linealización por realimentación mediante matemática lagrangiana. El objetivo de este estudio es el análisis del comportamiento del modelo y las diferentes técnicas de regulación ante situaciones realistas de control en tiempo real. Para ello, se han introducido retrasos que simulan el tiempo que pueden tardar las tramas de información en llegar a su destino. Esto ha permitido vislumbrar la robustez de sendas técnicas y comprobar si una predicción de la posición mejora la calidad del control. Para hacer esto, se ha modelado el robot en el entorno de Matlab/Simulink. Con la extensión de Simscape se definieron en primera instancia sus características físicas y dinámicas. Posteriormente, se utilizaron técnicas de sintonización para optimizar el rendimiento de los PIDs en términos de estabilidad y seguimientos de trayectorias. Más tarde, se diseñó el modelo matemático del robot mediante las leyes de Lagrange con el objetivo de construir un controlador multiarticular. Por último, se expuso el modelo a un entorno realista de control y se construyó un predictor lineal de posición., [Abstract] This article presents the modeling and control of a robot with two degrees of freedom using different methodologies such as the Proportional-Integral-Derivative (PID) regulator and Feedback linearization using Lagrangian equations. The objective of this study is the analysis of the behavior of the model and the different control techniques in real time. To do this, delays have been introduced that simulate the time that information frames take to reach their destination. This has allowed us to check the robustness of the communication paths and see if position prediction improves the quality of the control. The robot has been modeled with Matlab/Simulink. With the Simscape extension, its physical and dynamic characteristics were first defined. Subsequently, tuning techniques were used to optimize the performance of the PIDs in terms of stability and trajectory tracking. Later, the mathematical model of the robot was obtained using Lagrange's laws with the aim of building a multi-joint controller. Finally, the model was exposed to a realistic control environment and a linear position predictor was implemented.

- Abstract
The objective of this document is to study and verify the development and improvements in Unmanned Aircraft Systems (UAS) for difficult access environments since this matter is a critical area of research and innovation. As the use of UAS in various applications continues to expand, the need for these systems to operate in challenging environments such as mountainous terrain, dense forests, or urban areas with high-rise structures is increasing. The main motivation to start developing this project was the challenge exposed in the Xprize Rainforest Competition. The $10M XPRIZE Rainforest is a five-year competition to enhance the understanding of the rainforest ecosystem. I am part of the semifinalist team, Providence Plus, a multidisciplinary team composed by scientists from UPC, CSIC, MIT, and TUDelf. The purpose of this challenge is to obtain the maximum amount of information on biodiversity in the rainforest, using drone technology in this type of environment, with all the difficulties inherent in this environment that must be overcome and that are also the subject of analysis in this work, to propose and compare the different solutions and technologies to achieve the objectives of said challenge. As resources for competing in Xprize Challenge are limited and the final solution shall be scalable, the technologies evaluated must be cost efficient and practical. The first difficulty in this kind of environments is the signal strength and signal quality, not only for the drone commands but for the video and telemetry data. In this work, different solutions will be compared since analogic to digital technology. The second difficulty is autonomy, in terms of energetic supply. Taking into account the Rainforest environment and environmental policies, the most suitable technology available is batteries. There are several types of batteries that are suitable for drones, depending on the size, weight, and specifications of the drone. There will be a comparison between the, Objectius de Desenvolupament Sostenible::15 - Vida d'Ecosistemes Terrestres, Objectius de Desenvolupament Sostenible::13 - Acció per al Clima
