Development of cryptogames with Unity on an Ethereum Blockchain Test Network: Case Study and Challenges

The development of software aligned with Web3 innovations is essential to stimulate discussions on the application of these technologies in the scientific realm. This study presents the development of a 'cryptogame,' a game that integrates blockchain technology to incorporate Non-Fungible Tokens (NFTs) into its functionalities. The paper explores fundamental Web3 concepts, with references to relevant literature, and details the development process, including the methodologies and models adopted. As a result, a puzzle game was created that utilizes NFTs as playable characters, allowing for the transfer of these assets between digital wallets. Furthermore, the study investigates the application of these concepts in adapting a traditional mobile game for the use of NFTs, demonstrating the necessary changes in user interface and game mechanics to support the integration with digital assets

Uma aplicação de voz sobre IP baseada no Session Initiation Protocol

Neste trabalho é implementada uma aplicação de Voz Sobre IP utilizando o Session Initiation Protocol (SIP) como protocolo de sinalização. Para alcançar este objetivo, são analisadas algumas tecnologias importantes, como os protocolos da Internet Engineering Task Force (IETF) para Telefonia IP, codificadores de voz, e a utilização da aplicação para verificação de atrasos, jitter e perda de pacotes. A aplicação foi desenvolvida em Java e pode facilmente ser modificada para adequar novos codificadores de voz e características mais recentes que novas especificações do SIP possam implementa

Validity of the TBApp mobile application for self-care management for people with tuberculosis

ABSTRACT Objectives: to describe the validity process of the TBApp mobile application for self-care management for people with tuberculosis linked to Primary Health Care. Methods: methodological research developed with ten expert judges, carried out virtually. The application was assessed in relation to content and technology quality in seven domains (objectivity; structure and appearance; relevance; functionality; reliability; usability; and efficiency), using an instrument with a Likert scale. Results: TBApp was considered valid, relevant, functional, reliable and effective by expert judges. The objectives, structure and presentation and relevance domains presented an overall Content Validity Index of 0.93, and the functionality, reliability, usability and efficiency domains presented characteristics and sub-characteristics values greater than 0.80. Conclusions: TBApp is a creative and innovative tool that can be used by people with TB and disseminated in the scientific community
