Development of Ontology Aware of Information Quality for the Improvement of Situational Awareness in the Field of Emergency Management

Artigo apresentado no I Workshop de Informação, Dados e Tecnologia, realizado entre nos dias 04 e 06 de setembro de 2017, na cidade de Florianópolis (SC), no Auditório do Espaço Físico Integrado (EFI) da Universidade Federal de Santa Catarina (UFSC).Uma questão desafiadora na comunidade da Avaliação da Situação é determinar como o processo de avaliação pode ser redesenhado para o aprimoramento da Consciência da Situação (SAW), que pode ser severamente degradada se dados de baixa qualidade propagarem pelo processo comprometendo assim a tomada de decisões. Em sistemas de gerenciamento de emergências o grande desafio de adquirir e manter a SAW em operadores humano, é o consumo em excesso de dados em um ambiente dinâmico. O presente trabalho tem por objetivo o desenvolvimento de uma ontologia de domínio para o gerenciamento de emergências mais especificamente sobre incêndios florestais visando contribuir para a representação de informações, contribuindo assim com processos de avaliação de situações de fogo. Para tal, foram desenvolvidas entrevistas com especialistas, modelagem conceitual das tarefas e objetivos e o emprego de ferramentas e metodologias para a construção da ontologia que ao final será incorporada ao sistema “Distrito Federal Sem Fogo” (DF100Fogo).A challenging issue in the Situation Assessment community is to determine how the assessment process can be redesigned to improve Situation Awareness (SAW), which can be severely degraded if poor quality data propagate through the process, thereby compromising decision-making. In emergency management systems, the great challenge of acquiring and maintaining SAW in human operators is consuming too much data in a dynamic environment. The present work has the objective of developing a domain ontology for the emergencies management, more specifically about forest fires, aiming to contribute to the representation of information in this domain, thus contributing to fire assessment processes. To this end, interviews with specialists, conceptual modeling of tasks and objectives and the use of tools and methodologies for the construction of the ontology were developed, which in the end will be incorporated into the Distrito Federal Sem Fogo (DF100Fogo) system

Os cariótipos de Trinomys moojeni (Pessôa, Oliveira & Reis, 1992) e de Trinomys setosus elegans (Lund, 1841) (Rodentia, Echimyidae) de Minas Gerais, leste do Brasil

Two new karyotypes of species in the genus Trinomys are described from specimens collected recently in Morro do Pilar and Santa Bárbara, Minas Gerais State (MG), Brazil. Trinomys moojeni from Morro do Pilar had 2n=56 and FN=106 and T. setosus elegans from Santa Bárbara had 2n=56 and FN=104. Besides the differences in FN, different morphologies in the sex chromosomes also had been detected. These results at chromosomal level corroborate findings from the mitochondrial genome that suggest that T. s. elegans belongs to a clade composed by T. s. setosus and T. s. denigratus. The chromosomal data corroborated the inclusion of T. moojeni in this clade, as previously suggested on the basis of cranial morphology evidence.Dois novos cariótipos são descritos para espécies do gênero Trinomys com base em coletas recentes nos municípios de Morro do Pilar e Santa Bárbara no Estado de Minas Gerais (MG). Trinomys moojeni de Morro do Pilar apresentou o cariótipo com número diplóide (2n) igual a 56 e número fundamental (NF) igual a 106 e T. setosus elegans de Santa Bárbara apresentou 2n=56 e NF=104. Além da diferença nos valores de NF, diferenças na morfologia cromossômica do par sexual também foram detectadas. Os resultados no nível cromossômico corroboram aqueles encontrados com base no genoma mitocondrial, que evidenciou que T. s. elegans pertence a um clado composto por T. setosus setosus e T. s. denigratus. Os dados cromossômicos corroboraram a inclusão de T. moojeni neste clado, como previamente sugerido com base em evidências da morfologia craniana

Meningoencefalite chagásica: relato de caso de doença recentemente incluida como indicativa de AIDS no Brasil

Recently, reactivation of Chagas disease (meningoencephalitis and/or myocarditis) was included in the list of AIDS-defining illnesses in Brazil. We report a case of a 52-year-old patient with no history of previous disease who presented acute meningoencephalitis. Direct examination of blood and cerebrospinal fluid (CSF) showed Trypanosoma cruzi. CSF culture confirmed the diagnosis. Serological assays for T. cruzi and human immunodeficiency virus (HIV) were positive. Despite treatment with benznidazol and supportive measures, the patient died 24 hours after hospital admission. In endemic areas, reactivation of Chagas disease should always be considered in the differential diagnosis of meningoencephalitis among HIV-infected patients, and its presence is indicative of AIDS.Recentemente, a reagudização da doença de Chagas (meningoencefalite e/ou miocardite) foi incluída na lista de doenças indicativas de aids no Brasil. Os autores relatam o caso de um paciente de 52 anos de idade, natural de área rural da Bahia e procedente de uma área urbana de São Paulo, sem história de doenças prévias e que apresentou meningoencefalite aguda. As sorologias e pesquisas parasitológicas diretas no sangue e no liquido cefalorraquideano (LCR) demonstraram presença de Trypanosoma cruzi, confirmando-se o diagnóstico mediante cultura do LCR. O teste rápido assim como os ELISA e Western Blot diagnosticaram infecção pelo vírus da imunodeficiência humana (HIV). Apesar do tratamento com benzonidazole e as medidas de suporte, o paciente faleceu 24 horas depois da admissão hospitalar. Em áreas endêmicas, a reagudização da doença de Chagas deve ser sempre considerada no diagnóstico diferencial das meningoencefalites e sua presença em pacientes com infecção pelo HIV é indicativa de aids

Four new coordination polymers involving transition metals with 1,2,4,5-benzenetetracarboxylate and pyridyl-donor ligand di(4-pyridyl) sulfide

AbstractFour new coordination polymers namely {[Mn2(BT)(DPS)2(H2O)6]·10H2O}n (MnBTDPS), {[Co2(BT)(DPS)2(H2O)6]·10H2O}n (CoBTDPS), {[Cu2(BT)(DPS)(H2O)4]·5H2O}n (CuBTDPS) and {[Zn2(BT)(DPS)2]·6H2O}n (ZnBTDPS), where BT=1,2,4,5-benzenetetracarboxylate and DPS=di(4-pyridyl) sulfide, were synthesized and characterized by thermal analysis, vibrational spectroscopy (Raman and infrared) and single crystal X-ray diffraction analysis. In all compounds, the DPS ligands are coordinated to metal sites in a bridging mode and the carboxylate moiety of BT ligands adopts a monodentate coordination mode, as indicated by the Raman spectra data through the Δν (νasym(COO)−ν sym(COO)) value. According to X-ray diffraction analysis, MnBTDPS and CoBTDPS are isostructural and in these cases, the metal centers exhibit a distorted octahedral geometry. In CuBTBPP, the Cu2+ centers geometries are best described as square-pyramids, according to the trigonality index τ=0.14 for Cu1 and τ=0.10 for Cu2. On the other hand, in ZnBTDPS, the Zn2+ sites adopt a tetrahedral geometry. Finally, the four compounds formed two-dimensional sheets that are connected to each other through hydrogen bonding giving rise to three-dimensional supramolecular arrays

Soybean (Glycine max) as a versatile biocatalyst for organic synthesis

A series of aliphatic and aromatic aldehydes and ketones were reduced using plant cell preparations of Glycine max seeds (soybean). The biotransformation of five aromatic aldehydes in water, at room temperature afforded the corresponding alcohols in excellent yields varying from 89 to 100%. Two prochiral aromatic ketones yielded the alcohol in very low conversion, 1% and to 4%; however with good enantiomeric excess (ee) of 99 and 79%, respectively. Additionally, three prochiral and one cyclic aliphatic ketones produced the corresponding alcohols in moderate yields varying from 10 to 58% and ee varying from 73 to 99%. Hydrolysis of two aromatic esters yielded the expected carboxylic acids in 49 and 66%. Most of the obtained alcohols have commercial value as cosmetic fragrances. Although, the enzymes present in soybean (reductase/lipase) has not been defined, the reaction is an important route for the preparation of pure alcohols and carboxylic acid, with low cost and environmental impact.Keywords: Glycine max, biocatalysis, bioreduction, aldehydes and ketones, ester hydrolysi

Use and traditional management of Anadenanthera colubrina (Vell.) Brenan in the semi-arid region of northeastern Brazil

The use and management of "angico" (Anadenanthera colubrina (Vell.) Brenan) by a rural community in northeastern Brazil was examined. By employing different techniques of data collection and population structure analysis, it was determined that this species had multiple uses within the local community (especially as timber and for other wood products), and that local management of this species is based on simple maintenance and harvesting of individuals in agroforest homegardens. The study of the population structure of this tree species indicated that management and conservation strategies must include the participation of the local community

Electrochemical feasibility study of methyl parathion determination on graphite-modified basal plane pyrolytic graphite electrode

A low-cost electrochemical method was developed for the determination of trace-level of methyl parathion (MP) based on the properties of graphite-modified basal plane pyrolytic graphite electrode (graphite-bppg). A combination of graphite-bppg with square-wave voltammetric (SWV) analysis resulted in an original, sensitive and selective electrochemical method for determination of MP pesticide in drinking water. The electrode was constructed and the electrochemical behavior of MP was studied. Immobilization is achieved via film modification from dispersing graphite powder in deionized water and through pipeting a small volume onto the electrode surface allowing the solvent to volatilize. The strong affinity of the graphite modifier for the phosphorous group of the MP allowed the deposition of a significant amount of MP in less than 60 seconds. The cyclic voltammetric results indicate that the graphite-bppg electrode can enhance sensitivity in current intensity towards the quasi-reversible redox peaks of the products of the cathodic reduction of the nitro group at negative potential (peak I = 0.077 V and peak II = -0.062 V) and that the cathodic irreversible peak (peak III = -0.586 V) in comparison with bare bppg electrode and is also adsorption controlled process. Under optimized conditions, the concentration range and detection limit for MP pesticide are respectively 79.0 to 263.3 μmol L-1 and 3.00 μmol L-1. The proposed method was successfully applied to MP determination in drinking water and the performance of this electrochemical sensor has been evaluated in terms of analytical figures of merit.Um método eletroquímico de baixo custo foi desenvolvido para a determinação de traços de metil paration (MP) baseado nas propriedades do eletrodo de grafite pirolítico de plano basal modificado com grafite (grafite-bppg). A combinação do grafite-bppg com voltametria de onda quadrada (VOQ) resultou em um método eletroquímico seletivo, sensível e original para a determinação do pesticida MP em água potável. O eletrodo foi construído e o comportamento eletroquímico do MP foi estudado. A imobilização foi feita através de modificação por formação de filme a partir da dispersão de pó de grafite em água destilada e através de pipetagem de um volume pequeno sobre a superfície do eletrodo, permitindo que o solvente volatilizasse. A forte afinidade do modificador grafite com o grupo fósforo do MP permitiu o depósito de uma quantidade significativa de MP em menos de 60 segundos. Os resultados de voltametria cíclica mostraram que o eletrodo de grafite-bppg pode aumentar a sensibilidade na intensidade de corrente para os picos redox quasi-reversíveis dos produtos da redução catódica do grupo nitro em potencial negativo (pico I = 0,077 V e o pico II = -0,062 V) e para o pico catódico irreversível (pico III = -0,586 V) em comparação com o eletrodo não modificado bppg e que o processo é também controlado por adsorção. Sob condições otimizadas, o intervalo de concentração e limite de detecção para o pesticida MP são 79,0 a 263,3 μmol L-1 e 3,00 μmol L-1, respectivamente. O método proposto foi aplicado com sucesso → determinação do MP em água potável e o desempenho deste sensor eletroquímico foi avaliado em termos de figuras de mérito analíticas
