Review article of International Journal of Communications and Networks TELEODONTOLOGY IN COVID-19 TIMES: WHY NOT? Priscylla Rejane Salviano Vieira dos Anjos1, Maria Luiza Vaz de Oliveira Cunha1, Camila Eduarda de França Câmara1, Cíntia Natali Pontes Dos Santos1, Maria Tereza Nascimento Filgueiras Andrade1, Aurora Karla de Lacerda Vidal1 1Universidade de Pernambuco, Hospital Universitário Oswaldo Cruz, Faculdade de Ciências Médicas, Recife, Pernambuco, Brasil. Objective: To verify in te literature what the articles refer to about teleodontology in Covid-19 times. Methods: This is a bibliographic study, critical Reading of a scientific article, like a narrative review carried out through research of scientific articles in the SCIELO, PUBMED and LILACS databases, based on the keywords: Covid-19; Dentistry; Teleodontology. Results: Teleodontology was approved in Brazil, by the Federal Council of Dentistry, in resolution CFO-226, of June 4, 2020, which regulates the practice of distance dentistry (CFO, 2020), however teleconsultations are prohibited (virtual diagnosis) and teleprescriptions. The literature is unanimous in recognizing that the new social, educational and assistance reality favors the use of teleodontology as a complemente to traditional teaching methods and resource capable of assistin patient care, contributing to the improvement and controlo f oral health, care integral and humanized mediated by technology. However, in Brazil, technology is still not available to everyone, which may result in limiting learning, assistance and aggravating existing social inequality. Conclusion: Teleodontology proved to be a valuable technological tool and can be excelente, allowing interaction and integration, in the teaching/learning process, as well as in teleassistance, provided that all actors have access to the internet and know how to use it.

Research article of International Journal of Communications and Networks FACT-CHECKING: AN IMPORTANT TOOL TO COMBAT FAKE NEWS ON HEALTH IN COVID-19 PANDEMIC Esther Gomes Muniz Rocha¹*, Josué Miguel de Oliveira¹, Kelly Cristina Pereira de Araújo¹, Maria Eduarda Santos Teperino Abreu¹, Mariana Rodrigues Sandes da Silva¹, Thais Ranielle Souza de Oliveira¹. ¹Centro Universitário Euro-Americano (UNIEURO) Objective: To demonstrate the importance of Fact-Checking tools in combating health fake news in the COVID-19 pandemic. Methods: Quantitative descriptive study, conducted during the Sars-Cov-2 pandemic. Fake news were accounted and identified through the website, registered in the Agência Lupo and Aos Fatos checking platforms, belonging to the International Fact-Checking Network, an international understanding with recognized news verification methodologies. The registered news originated from the social media/networks Facebook, Whatsapp, Instagram, Twitter, and websites. They were later classified according to content in Conspiracy Theory, Prevention/Treatment/Cure, Authorities/Agency Measures, Situation of a city, state and country, Causes, Symptoms, Public Figure and False Context. Results: 529 fake news about coronavirus were obtained, of these 306 were from the Agência Lupo platform, and 223 from the Aos Fatos platform.  A total of 99 (18.72%) fake news were about Conspiracy Theory 99 (18.72%) Authorities/Agency Measures and 98 (18.53%)  False Context. As for the origin of fake news 382 (72.21%) were from Facebook and 67 (12.66%) from Whatsapp. Conclusion: The Fact-Checking tools in combating misinformation on social networks are important because they deny false news, unlikely allegations, and no justification related to the Covid-19 pandemic.  These check sites alert social networks, policymakers, and the public to create measures that educate and protect the integrity and health of individuals and prevent them from falling victim to misinformation.

Traffic Evaluation Model of the Opening Road in Residential area based on VISSIM simulation

Research article of International Journal of Communications and Networks Traffic Evaluation Model of the Opening Road in Residential area based on VISSIM simulation Boying Lv1*, Guozhi Li1, Tianlong Wang2, Yishuai Tian1 1College of Hydraulic & Environmental Engineering, China Three Gorges University, Yichang 443002, China. 2College of Civil Engineering & Architecture, China Three Gorges University, Yichang, 443002, China. With the increasing urban road traffic pressure in closed residential areas, the problem of road patency in residential areas has become a hot topic. This paper established a traffic evaluation Model of the opening community based on VISSIM simulation. We constructed different types of residential areas, and compared the impact on traffic after opening different kinds of areas. With the analytic hierarchy process, we selected ten important indicators from three aspects. Then, the parameters of the road structure were put in the VISSIM simulation, and quantitatively analyze the impact of various types of residential areas opening. The results showed that changing the traffic rules at the intersection of the community has the greatest improvement in traffic capacity, reaching 89%. The influence of increasing the internal road and changing the external road structure of the city is more visible, reaching about 60%. The overall opening-up policy should be suitable for different localities. Keywords: Community opening; VISSIM; Traffic network; AHP ...

A Comparative Analysis of Four Path Optimization Algorithms

Review article of International Journal of Communications and Networks A Comparative Analysis of Four Path Optimization Algorithms Charles OKONJI *; Olawale J. OMOTOSHO; OGBONNA, A. C. Department of Computer Science, Babcock University Path / route optimization for promptly moving equipment and personnel from base to disaster location has remained a nagging challenges for effective emergency response particularly within the context of developing countries. Bad road networks, poor and outdated navigation systems, faulty transportation vehicles, and traffic congestion remain among the top challenges militating against effective emergency response, and this has resulted in mounting statistics of losses for lives and properties within such jurisdictions. The pressing question has been: how can emergency response itinerary be planned and scheduled most optimally and reliably in the face of these challenges? This research paper compares four of the more popular path / route optimization algorithms (the Ant Colony Optimization Algorithm, Dijkstra’s Algorithm, Bellman Ford’s Algorithm, and Suurballe’s Algorithm), in order to determine the trade-offs and advantages that they present with respect to each other, and propose actionable recommendations for implementation. The findings of this research would prove useful for emergency response planning, particularly within the context of developing countries where these challenges are commonplace.
