RESUMO

Protecting sensitive patient data, such as electrocardiogram (ECG) signals, during RF wireless transmission is essential due to the increasing demand for secure telemedicine communications. This paper presents an innovative chaotic-based encryption system designed to enhance the security and integrity of telemedicine data transmission. The proposed system utilizes a multi-scroll chaotic system for ECG signal encryption based on master-slave synchronization. The ECG signal is encrypted by a master system and securely transmitted to a remote location, where it is decrypted by a slave system using an extended state observer. Synchronization between the master and slave is achieved through the Lyapunov criteria, which ensures system stability. The system also supports Orthogonal Frequency Division Multiplexing (OFDM) and adaptive n-quadrature amplitude modulation (n-QAM) schemes to optimize signal discretization. Experimental validations with a custom transceiver scheme confirmed the system's effectiveness in preventing channel overlap during 2.5 GHz transmissions. Additionally, a commercial RF Power Amplifier (RF-PA) for LTE applications and a development board were integrated to monitor transmission quality. The proposed encryption system ensures robust and efficient RF transmission of ECG data, addressing critical challenges in the wireless communication of sensitive medical information. This approach demonstrates the potential for broader applications in modern telemedicine environments, providing a reliable and efficient solution for the secure transmission of healthcare data.

RESUMO

The COVID-19 pandemic was a challenging period for young people in Mexico, particularly those already contending with social and structural inequality. In March 2021, the Colectivo Frontera, a research collective based in Mexico City, Mexico, which works on advancing equity and psychosocial wellbeing among marginalized communities, carried out an 8-week, online project to provide psychosocial support and promote resilience for marginalized young people from different locations in Mexico. The project entailed weekly journaling with the Pandemic Journaling Project (PJP), as well as weekly phone sessions with a mental health specialist who provided emotional support (acompañamiento emocional) through practices of active listening. The project culminated in the Escucha (Listen) Podcast for which each youth participant created an episode about their experiences during the pandemic. Many also submitted a photo to accompany their recording; one produced a song. Participant episodes were compiled into a series of five chapters. Each chapter of the podcast centers on a common theme, including reflections on loved ones lost to COVID-19, social fragmentation, gender-based constraints on expressing emotions, and the experiences and perspectives of children. The project provides a compelling example of a low-cost approach to providing support for the mental health and wellbeing of marginalized young people. It also demonstrates the importance of creating projects that help young people make meaningful connections and that leverage their creativity to foster resilience, improve social cohesion, and elevate their perspectives and voices.

RESUMO

BACKGROUND: Stunting and micronutrient deficiencies have persistently affected children in the Brazilian Amazon for decades. However, in recent years, a notable increase in childhood overweight prevalence has been observed, particularly in the context of heightened food insecurity exacerbated by the COVID-19 pandemic. Despite the limited number of effective solutions proposed to tackle this problem, digital interventions have shown great promise worldwide in preventing obesity and promoting healthy diets. OBJECTIVE: This study aims to describe the protocol of a family-based WhatsApp intervention, specifically designed to investigate the efficacy of multimedia messaging in preventing excessive weight gain and improving healthy eating practices among school-aged children in the Amazon region. METHODS: This study protocol outlines a theory-driven randomized controlled trial based on the cognitive theory of multimedia learning and the social cognitive theory. A total of 240 parents or caregivers of children enrolled in the Maternal and Child Health and Nutrition Cohort Study in Acre (MINA-Brazil) will be recruited by phone and social media. The intervention group will receive persuasive multimedia messages through WhatsApp over 19 weeks, while the waitlist control group will remain in the usual care. The primary outcome is a change in children's BMI in z score. Secondary outcomes are changes in dietary intake and biochemical indicators of the children. Outcome measures will be assessed at baseline and 5 months after randomization in comparison to usual care. The analysis will use an intent-to-treat approach and will be conducted using the statistical package Stata (version 18.0), with a significance level set at P<.05. Paired and unpaired 2-tailed t tests will be applied to compare mean changes in the outcomes. RESULTS: Data collection started in June 2023, and final measurements are scheduled to be completed in December 2023. The results of the main analysis are expected to be available in 2024. CONCLUSIONS: This innovative multimedia message intervention holds significant potential for fostering behavioral changes among Amazonian children.

ABSTRACT Introduction: Villa Clara is the oldest province in the country, since middle-aged adults occupy a high percentage of its population. During this stage of life, although some physiological changes are due to individuals' genetic and biological factors, it is also important to consider the influence of lifestyle, experienced in the current quality of life in middle-aged adults, which can be improved with physical activity. Objective: to design a multimedia, at the Faculty of Health Technology and Nursing in the University of Medical Sciences of Villa Clara, as an educational and instructive tool to improve the quality of life in middle-aged adults. Methods: a technological innovation study was carried out from September 2018 to September 2019. The universe of study consisted of 397 teachers, who constituted the total number of full-time teachers; the sample was 40 teachers. Those who were not in the age range corresponding to middle-aged adults were considered as an exclusion criterion. Age, weight, height, gender, physical exercises, non-communicable chronic diseases and type of diet were among the variables studied. Theoretical, empirical and mathematical-statistical methods were used. Results: the final product provided benefits, since middle-aged adults were motivated towards the development of skills and abilities, allowing them to make correct decisions in order to improve their quality of life. Conclusions: educational multimedia is a novel and motivating way to influence the quality of life in middle-aged adults.

RESUMO

Resumo Objetivo: Identificar o perfil de utilização dos recursos didáticos pelos médicos radiologistas e residentes em radiologia e diagnóstico por imagem brasileiros. Materiais e Métodos: Estudo observacional, transversal e descritivo, realizado por meio de questionário eletrônico contendo perguntas referentes ao perfil do médico, formação, local de atuação, perfil de acesso a recursos educacionais e tipos de recursos mais utilizados. Resultados: Responderam ao questionário 265 médicos com idade média de 38,2 anos, sendo a maioria radiologistas formados (170; 64,2%), do sexo masculino (166; 62,6%), trabalhando em instituições privadas (174; 65,7%), sem vínculo acadêmico (167; 63,0%), atuando principalmente nas áreas de ultrassonografia (212; 80,0%) e tomografia computadorizada (206; 77,7%). A carga horária média de estudo semanal foi de 9,6 horas (mediana: 6 horas), sendo maior no grupo dos médicos que estão em formação e nos que atuam em instituições públicas e acadêmicas. Quanto ao recurso para o acesso do material de estudo, observou-se uma tendência pela maior utilização do computador (65,3%). A maioria dos respondentes optou por acessar materiais didáticos sem custo (61,9%), sendo os sites da web, livros e revistas eletrônicas os mais pesquisados. Conclusão: Os radiologistas brasileiros utilizam recursos eletrônicos e digitais como principais materiais didáticos, sendo os sites da web, livros e revistas eletrônicas as fontes mais utilizadas.

RESUMO

Video streaming currently dominates global Internet traffic. Live streaming broadcasts events in real-time, with very different characteristics compared to video-on-demand (VoD), being more sensitive to variations in delay, jitter, and packet loss. The use of adaptive streaming techniques over HTTP is massively deployed on the Internet, adapting the video quality to instantaneous condition of the network. Dynamic Adaptive Streaming over HTTP (DASH) is the most popular adaptive streaming technology. In DASH, the client probes the network quality and adjusts the quality of requested video segment according to the bandwidth fluctuations. Therefore, DASH is an over-the-top application using unmanaged networks to distribute content in the best possible quality. In order to maintain a seamless playback, VoD applications commonly use a large reception buffer. However, in live streaming, the use of large buffers is not allowed because of the induced delay. Active Queue Management (AQM) arises as an alternative to control the congestion in router's queue, pressing the traffic sources to reduce their transmission rate when it detects incipient congestion. In this article, we evaluate the performance of recent AQM strategies for real-time adaptive video streaming. Furthermore, we propose a new AQM algorithm to improve the user-perceived video quality. The results show that the proposed method achieves better performance than competing AQM algorithms and improves the video quality in terms of average peak signal-to-noise ratio while keeping the fairness among concurrent flows.
