Diagnóstico de la situación actual de la tecnología 5G: Suramérica

This paper presents an analysis of the current state of 5G technology deployment in South American countries. The research is carried out employing an informal survey of the current regulations in mobile technologies, to later carry out a general overview of the most relevant aspects in the 13 South American countries and French Guiana. The commercial launches of 5G in the countries of Uruguay, Surinam, and Brazil are highlighted. The 3.5 GHz and 28 GHz spectrum bands are identified as potential for 5G development, used in a total of 26 tests distributed in 9 countries, except for Guiana, Paraguay, Venezuela, and French Guiana. Likewise, the countries with the highest spectrum release rate are Brazil with 609 MHz and Peru with 554.4 MHz, while Ecuador and Bolivia are the last ones in this aspect with 290 MHz and 284 MHz respectively, except for Argentina, the telecommunications sector in South America is decentralized, which means that there are several regulatory bodies. This study was conducted to review the current state of mobile technology in South America and obtain an overview of the actions carried out in the region for the implementation of 5G technology.Este trabajo presenta un análisis del estado actual del despliegue de tecnología 5G de los países de Suramérica. La investigación se realiza por medio de un levantamiento de información de la normativa vigente en tecnologías móviles para posteriormente realizar una visión general de los aspectos más relevantes en Suramérica. Se destacan los lanzamientos comerciales del 5G de los países de Uruguay, Surinam y Brasil. Se identifican las bandas del espectro de 3,5 GHz y 28 GHz como potenciales para el desarrollo 5G, utilizadas en un total de 26 pruebas distribuidas en 9 países, exceptuando a la Guyana, Paraguay, Venezuela y la Guyana Francesa, así mismo, los países que cuentan con un mayor índice de liberación de espectro son Brasil con 609 MHz y Perú con 554,4 MHz mientras que Ecuador y Bolivia son los últimos en este aspecto con  290 MHz y 284 MHz respectivamente, a excepción de Argentina el sector de las telecomunicaciones en Suramérica es descentralizado esto quiere decir que existen varios organismos reguladores. Este estudio fue realizado con la finalidad de revisar el estado actual de la tecnología móvil en Suramérica y obtener una visión general de las acciones llevadas a cabo en la región para la implementación de la tecnología 5G

Validity of the Spanish Version of the Vaccination Attitudes Examination Scale

Individuals vary in the extent to which they have unfavorable attitudes towards vaccines. The Vaccination Attitudes Examination (VAX) Scale is a recently developed brief 12-item questionnaire created to better understand general vaccination attitudes. The current research aimed at providing a Spanish adaptation of the VAX Scale. After conducting an initial pilot study, Exploratory and Confirmatory Factor Analysis showed that the Spanish version of the scale had good internal consistency and factor structure (Study 1), discriminant validity from other individual differences measures (such as the Beliefs about Medicine Questionnaire and the Medical Mistrust Index) as well as good predictive validity of relevant vaccination-related outcomes (Study 2). In conclusion, in the present research, the Spanish version of the VAX scale proved to have a high internal consistency, showed convergent validity with other conceptually similar constructs, and successfully predicted vaccination intentions and vaccination decisions. Having this scale available in Spanish will allow researchers to analyze vaccination processes and vaccine hesitancy over a great number of people
