An Anomaly-based Intrusion Detection System in Presence of Benign Outliers with Visualization Capabilities

Abnormal network traffic analysis through Intrusion Detection Systems (IDSs) and visualization techniques has considerably become an important research topic to protect computer networks from intruders. It has been still challenging to design an accurate and a robust IDS with visualization capabilities to discover security threats due to the high volume of network traffic. This research work introduces and describes a novel anomaly-based intrusion detection system in presence of long-range independence data called benign outliers, using a neural projection architecture by a modified Self-Organizing Map (SOM) to not only detect attacks and anomalies accurately, but also provide visualized information and insights to end users. The proposed approach enables better analysis by merging the large amount of network traffic into an easy-to-understand 2D format and a simple user interaction. To show the performance and validate the proposed visualization-based IDS, it has been trained and tested over synthetic and real benchmarking datasets (NSL-KDD, UNSW-NB15, AAGM and VPN-nonVPN) that are widely applied in this domain. The results of the conducted experimental study confirm the advantages and effectiveness of the proposed approach

Hepatitis B virus DNA in sera of blood donors and of patients infected with hepatitis C virus and human immunodeficiency virus

With the use of PCR, we searched for hepatitis B virus (HBV) DNA in serum samples from 415 HBsAg-negative, anti-HBc-positive patients: 150 were blood donors, 106 had only hepatitis C virus (HCV) infection, and 159 had human immunodeficiency virus (HIV) infection (of which 88 were HCV positive and 71 were HCV negative). HBV DNA was detected in 4% of blood donors, 3.4% of HIV- and HCV-positive patients, and 24% of HCV-positive patients.10471872

High prevalence of GB virus C in Brazil and molecular evidence for intrafamilial transmission

The prevalence of GB virus C (GBV-C) in candidate Brazilian blood donors with normal and elevated alanine aminotransferase levels was found to be 5.2% (5 of 95) and 6.5% (5 of 76), respectively. Among Brazilian patients, GBV-C was Found in 9.5% (13 of 137) of cases of hepatitis not caused by hepatitis A,virus (HAV), HBV, HCV, HDV, or HEV (non-A-E hepatitis) and in 18.2% (8 of 44) of individuals infected with HCV. Molecular characterization of GBV-C by partial sequencing of the NS3 region showed clustering between members of a single family, implying intrafamilial transmission. In conclusion, these results together suggest that contagion mechanisms which facilitate intrafamiliar transmission of GBV-C may partially explain the high prevalence of viremic carriers worldwide.3751634163

Utilização de serviços de reabilitação pelas crianças e adolescentes dependentes de tecnologia de um hospital materno-infantil no Rio de Janeiro, Brasil Use of rehabilitation services by technology-dependent children and adolescents in a maternal and child hospital in Rio de Janeiro, Brazil

O objetivo deste estudo é caracterizar descritivamente a dependência tecnológica e a utilização de serviços de reabilitação pela população de crianças e adolescentes de um hospital materno-infantil do Rio de Janeiro, Brasil. O estudo transversal descreveu as características demográficas da criança e sócio-econômicas do cuidador e família, como também o tipo de dependência tecnológica e a utilização de serviços de reabilitação. A população do estudo é composta de pré-escolares (56,3%), do sexo masculino (58,3%), residentes na região metropolitana do Estado do Rio de Janeiro (89,6%). São oriundos de famílias com rendimentos mensais até dois salários mínimos (70,9%), cuidados sobretudo por suas mãe (93,8%), que possuem escolaridade menor ou igual ao ensino fundamental (54,2%) e não trabalham (89,6%). Dos entrevistados, um total de 22,9% depende de três tipos diferentes de tecnologias, sendo o suporte medicamentoso (87,5%) a mais utilizada. O tratamento de reabilitação é financiado preponderantemente pelo Sistema Único de Saúde (SUS) e instituições filantrópicas, sendo o fisioterapeuta motor (60,4%) o profissional de maior demanda nesse tratamento. O hospital estudado concentra todos os atendimentos médicos especializados e a maior parte dos tratamentos em reabilitação.<br>The objective of this study was to describe the dependence on technology and use of rehabilitation services by children and adolescents in a maternal and child hospital in Rio de Janeiro, Brazil. Using a cross-sectional design, the following variables were analyzed: gender and age of the children and adolescents, socioeconomic characteristics of the family, technology dependence, and use of rehabilitation services. The majority of the study population consisted of preschoolers (56.3%), boys (58.3%), residing in Greater Metropolitan Rio de Janeiro (89.3%), from low-income families (70.9%), and cared for mainly by their mothers (93.8%), who in turn have low schooling (54.2%) and are unemployed (89.6%). Of the entire study population, 22.9% were dependent on more than three different technologies, with medication as the most prevalent. Government and nonprofit institutions fund the rehabilitation, and physical therapists are the most widely used health professionals during treatment (60.4%). The target hospital provides all of the specialized medical treatment and most of the rehabilitation
