Atribuição de causalidade e eventos acidentais e a tomada de risco

Esta pesquisa teve por objetivo avaliar possíveis relações existentes entre Atribuição de causalidade e Tomada de Risco com relação a eventos acidentes, assim como a influência de algumas variáveis sobre o processo de Tomada de Decisão em situações de risco de acidentes. Para isto foram construídos 4 instrumentos e aplicados a 59 sujeitos operários não especializados de uma indústria de conservas de pescado no Rio de Janeiro. Dentre a mostra, 30 sujeitos são do sexo feminino e 29 do sexo masculino. As variáveis consideradas foram: sexo dos sujeitos, vitimação, consequência da Tomada de Risco, situação sob julgamento e local de trabalho dos sujeitos. Os instrumentos - aplicados a cada sujeito - em número de 4, sendo que dois deles versam sobre situações no trânsito e dois sobre situações no trabalho. Os resultad08 revelaram uma influência significativa de fatores sócio-culturais e psicológicos no processo de Tomada de Decisão diante de eventos acidentais, baseados na vivência de grupos de trabalho com relação a acidentes. Os resultados mostraram que os grupos se estruturam cognitivamente no sentido de tender a padronizar a forma explicativa dos acidentes com base na realidade vivida pelo grupo.

A antinomia existente entre as Convenções de Varsóvia e Montreal e o Código de Defesa do Consumidor: a questão da limitação da responsabilidade do transportador aéreo

O presente trabalho objetiva analisar, sob o ponto de vista doutrinário e jurisprudencial, a discussão sobre a antinomia entre as Convenções de Varsóvia e Montreal, que estipulam um teto máximo de indenizatório às vítimas de acidentes aéreos, e o Código de Defesa do Consumidor que, ao promover a proteção do consumidor, estabelece a indenização integral pelos danos sofridos pelo fato do serviço. Inicialmente, analisa-se regulação internacional do transporte aéreo no tocante ao regime de responsabilidade, atentando-se para sua evolução e origem histórica. Em seguida, contextualiza-se a proteção do consumidor no ordenamento jurídico brasileiro, ressaltando o regime de responsabilidade pelo fato do serviço e o princípio da reparação integral dos danos. Por fim, passa-se para a análise da antinomia existente entre os diplomas, buscando-se a melhor solução diante da atual realidade da sociedade brasileira.

A percepção dos riscos na atividade pericial: um estudo de caso, considerando a cultura da organização com um breve olhar fenomenológico à gestão

A pesquisa objetivou analisar e compreender, considerando os aspectos culturais da organização, como os servidores do Instituto de Criminalística percebem os riscos em seus ambientes interno e externo. A integração das dimensões investigadas (cultura, risco, percepção e gestão) a última sob um breve olhar fenomenológico, possibilitou desvelar até que ponto os valores da organização policial interferem na percepção dos riscos, adicionando uma contribuição às escassas publicações sobre o tema. Em busca da cultura da organização policial, uma incursão histórica esquadrinhou a linhagem da polícia e da Criminalística. No caminho metodológico, deparou-se com raras publicações sobre o tema, demandando um desenho específico para o estudo de caso, considerando o seu contexto atual, em caráter exploratório sobre o foco investigado. Uma abordagem qualitativa, acompanhada de dados estatísticos obtidos na própria instituição, favoreceu a compreensão do problema, envolvendo valores e riscos. Foram desenhadas planilhas ajustadas à realidade da unidade e orientadas aos gestores das seções internas e externas, configurando um mapa de risco do Instituto, resultando em um documento, sem precedentes, tipológico dos riscos na atividade pericial. Levantamento bibliográfico, documental, entrevistas e questionários, garantiram integridade à pesquisa. Em termos práticos, as identificações dos riscos (incluindo o mapa) e os esclarecimentos sobre a cultura, favorecerão, aos administradores, a programação de ações de gestão, visando à redução de instabilidades e tensões que contribuem para a ocorrência de acidentes e perdas no âmbito da criminalística. Concluiu-se, que a percepção e a própria gestão dos riscos são sensíveis às influências de valores culturais, exigindo dos gestores e administrados, em ação participativa, a construção de um ambiente redutor de instabilidades e tensões com a relevância do humano cuja essencialidade representou a senda de partida, de chegada e para retomada, na gestão organizacional.

Segurança e gestão de riscos na atividade pericial

Os riscos fazem parte da vida das pessoas quaisquer que sejam suas profissões ou atividades. No caso dos policiais estes riscos são ampliados devido às situações as quais estão sujeitos e em particular no caso dos peritos criminais federais, que além dos relacionados às suas atividades policiais tem outras que são inerentes à perícia. Esta dissertação teve como objetivo identificar os principais riscos de segurança no ambiente de trabalho dos peritos criminais da Polícia Federal. A pesquisa, sob seu ponto de vista metodológico foi classificada quanto à sua natureza como aplicada; no tocante à abordagem do problema se classifica como qualitativa e quanto aos seus objetivos trata-se de pesquisa descritiva. A respeito dos procedimentos técnicos a pesquisa foi classificada como bibliográfica, pesquisa de levantamento e estudo de caso com aplicação na perícia criminal federal. Para tanto foram utilizados instrumentos de coleta de dados online os quais foram disponibilizados para peritos criminais de todas as áreas e unidades de federação. Os dados demonstraram que apesar de existirem diversos riscos relacionados com a atividade-fim pericial há outros com potencial para se transformarem em acidentes, principalmente os relacionados com questões policiais como abordagens, missões e operações. Os riscos foram mapeados por áreas da perícia utilizando-se como base a NR-5 que trata dos mapas de riscos. Com a pesquisa provocou-se a discussão a respeito dos riscos a que estão sujeitos os peritos e com isso criou-se uma conscientização da necessidade de tratamento dos mesmos. Com a participação dos peritos de todas as áreas de formação e unidades da federação, conseguiu-se numa perspectiva qualitativa identificar os principais riscos por grupos (físicos, químicos, biológicos, ergonômicos e de acidentes). Conclui-se que se faz necessário, em caráter de urgência, maior aprofundamento e discussões a respeitos dos riscos, bem como a criação de procedimentos mínimos a serem adotados para que os mesmos não se concretizem. A visão necessária para tratar estes riscos não pode ficar restrita a área pericial, mas precisa ser estendida para toda a Polícia Federal, e precisa ser inserida na filosofia, práticas e processos que permitam criar uma verdadeira cultura de gestão estratégica de riscos.

Microinsurance: income risk, social security and the demand for private onsurance by low-income families

Insurance provision against uncertainties is present in several dimensions of peoples´s lives, such as the provisions related to, inter alia, unemployment, diseases, accidents, robbery and death. Microinsurance improves the ability of low-income individuals to cope with these risks. Brazil has a fairly developed financial system but still not geared towards the poor, especially in what concerns the insurance industry. The evaluation of the microinsurance effects on well-being, and the demand for different types of microinsurance require an analysis of the dynamics of the individual income process and an assessment of substitutes and complementary institutions that condition their respective financial behavior. The evaluation of the microinsurance effects on well-being, and the demand for different types of microinsurance require an analysis of the dynamics of the individual income process and an assessment of substitutes and complementary institutions that condition their respective financial behavior. The Brazilian government provides a relatively developed social security system considering other countries of similar income level which crowds-out the demand for insurance and savings. On the other hand, this same public infrastructure may help to foster microfinance products supply. The objective of this paper is to analyze the demand for different types of private insurance by the low-income population using microdata from a National Expenditure Survey (POF/IBGE). The final objective is to help to understand the trade-offs faced for the development of an emerging industry of microinsurance in Brazil.

Qualidade dos empregos e a carcinicultura marinha nos laboratórios da praia de Barreta/RN

To present research had for objective to study the quality of the employment in the maturation Laboratories and larviculture of the Beach of Barreta/RN, adopting for so much the criteria used by Reinecke(1999) to characterize a quality employment: surrender, benefits non salary, regularity and work reliability and of the wage, contractual status, social protection, work day, intensity of the work, risk of accidents and of occupational diseases, involvement in linked decisions to the section work, possibility for the development of professional qualifications. Of the exam of the data it was verified that the generated employments are considered employments of good quality. However, this result should be analyzed to the light of a context of extreme informality and of precarization of the work. Therefore, the results should be relativized. He/she/you imports to retain that one of the limitations of the study resides in the impossibility of generalizing the data for the whole section of the sea carcinicultura. In spite of that fact, he/she is considered that the objectives of the research were assisted fully and that the characterization of the profile of the employment generated by the section of the shrimpculture it is extremely important for the drawing of public politics gone back to foment this activity.

Análise do transcriptoma das glândulas venenosas do escorpião Tityus stigmurus

In Brazil, accidents with scorpions are considered of medical importance, not only by the high incidence, but also for the potentiality of the venom from some species in determining severe clinical conditions. Tityus stigmurus is a widely distributed scorpion species in Northeastern Brazil and known to cause severe human envenomations, inducing pain, hyposthesia, edema, erythema, paresthesia, headaches and vomiting. The present study uses a transcriptomic approach to characterize the molecular repertoire from the non-stimulated venom gland of Tityus stigmurus scorpion. A cDNA library was constructed and 540 clones were sequenced and grouped into 37 clusters, with more than one EST (expressed sequence tag) and 116 singlets. Forty-one percent of ESTs belong to recognized toxin-coding sequences, with antimicrobial toxins (AMP-like) the most abundant transcripts, followed by alfa KTx- like, beta KTx-like, beta NaTx-like and alfa NaTx-like. Our analysis indicated that 34% include other possible venom molecules , whose transcripts correspond to anionic peptides, hypothetical secreted peptides, metalloproteinases, cystein-rich peptides and lectins. Fifteen percent of ESTs are similar to cellular transcripts. Sequences without good matches corresponded to 11%. This investigation provides the first global view of cDNAs from Tityus stigmurus. This approach enables characterization of a large number of venom gland component molecules, which belong either to known or atypical types of venom peptides and proteins from the Buthidae family

Contribuição ao desenvolvimento de ontologias para processos petroquímicos : estudo de caso em uma planta DEA

In the last decades, the oil, gas and petrochemical industries have registered a series of huge accidents. Influenced by this context, companies have felt the necessity of engaging themselves in processes to protect the external environment, which can be understood as an ecological concern. In the particular case of the nuclear industry, sustainable education and training, which depend too much on the quality and applicability of the knowledge base, have been considered key points on the safely application of this energy source. As a consequence, this research was motivated by the use of the ontology concept as a tool to improve the knowledge management in a refinery, through the representation of a fuel gas sweetening plant, mixing many pieces of information associated with its normal operation mode. In terms of methodology, this research can be classified as an applied and descriptive research, where many pieces of information were analysed, classified and interpreted to create the ontology of a real plant. The DEA plant modeling was performed according to its process flow diagram, piping and instrumentation diagrams, descriptive documents of its normal operation mode, and the list of all the alarms associated to the instruments, which were complemented by a non-structured interview with a specialist in that plant operation. The ontology was verified by comparing its descriptive diagrams with the original plant documents and discussing with other members of the researchers group. All the concepts applied in this research can be expanded to represent other plants in the same refinery or even in other kind of industry. An ontology can be considered a knowledge base that, because of its formal representation nature, can be applied as one of the elements to develop tools to navigate through the plant, simulate its behavior, diagnose faults, among other possibilities

Avaliação de HPA e BTEX no solo e água subterrânea, em postos de revenda de combustíveis: estudo de caso na cidade de Natal -RN

The retail fuel stations are partially or potentially polluters and generators of environmental accidents, potentially causing contamination of underground and surface water bodies, soil and air. Leaks in fuel retail stations´ underground storage systems are often detected in Brazil and around the world. Monoaromatic hydrocarbons, BTEX (benzene, toluene, ethylbenzene and xylenes) and polycyclic aromatic hydrocarbons (PAHs) are an indication of the presence of contamination due to its high toxicity. This paper presents a case study of contamination in a Fuel Retail Station by petroleum derivative products in the city of Natal. For identification and quantification of the hydrocarbons, EPA analytical methods were used. The values of benzene quantified by EPA method 8021b CG-PID/FID, ranged from 1.164 to 4.503 mg.Kg-1 in soil samples, and from 12.10 to 27,639 μg.L-1 in underground water samples. Among the PAHs, naphthalene and anthracene showed the most significant results in soil samples, 0.420 to 15.46 mg.Kg-1 and 0.110 to 0,970 mg.Kg-1, respectively. In underground water samples, the results for Naphthalene varied between 0.759 and 614.7 μg.L-1. PAHs were quantified by EPA Method 8270 for GCMS. All of the results for the chemical analysis were compared with the values for the CONAMA 420/2009 resolution. The results for benzene (27,639 μg.L-1) showed levels highly above the recommended by the CONAMA 420 resolution, wherein the maximum permissible for underground water is 5 μg.L-1. This is a worrying factor, since underground water makes up 70% of the city of Natal´s water supply

Semiparametric modeling of the spatial distribution of occupational accident risk in the casual labor market, Piracicaba, southeast Brazil

The objective of this study was to estimate the spatial distribution of work accident risk in the informal work market in the urban zone of an industrialized city in southeast Brazil and to examine concomitant effects of age, gender, and type of occupation after controlling for spatial risk variation. The basic methodology adopted was that of a population-based case-control study with particular interest focused on the spatial location of work. Cases were all casual workers in the city suffering work accidents during a one-year period; controls were selected from the source population of casual laborers by systematic random sampling of urban homes. The spatial distribution of work accidents was estimated via a semiparametric generalized additive model with a nonparametric bidimensional spline of the geographical coordinates of cases and controls as the nonlinear spatial component, and including age, gender, and occupation as linear predictive variables in the parametric component. We analyzed 1,918 cases and 2,245 controls between 1/11/2003 and 31/10/2004 in Piracicaba, Brazil. Areas of significantly high and low accident risk were identified in relation to mean risk in the study region (p < 0.01). Work accident risk for informal workers varied significantly in the study area. Significant age, gender, and occupational group effects on accident risk were identified after correcting for this spatial variation. A good understanding of high-risk groups and high-risk regions underpins the formulation of hypotheses concerning accident causality and the development of effective public accident prevention policies.

Representações sociais sobre o acidente de trabalho em saúde

The aim of the present study was to identify the representational elements of workrelated accidents in the health field, as well as investigate their most frequent occurrences at a university hospital, seeking to understand the cognitive, affective and social elements subjacent to the work process involved in health. The analysis focused on 470 middle and senior support staff of this hospital, based on the theoretical-methodological support of the Social Representations Theory. A combination of the following instruments was used for data collection: a free wordassociation test, a questionnaire, an interview and a field journal. Evoc 2000 software was used to identify representational structure. Chi-square and Mann-Whitney tests, at a significance level of 5%, were performed to verify the association between the independent variables and the occurrence of work accidents. In addition, thematic content analysis and lexicographic analysis by ALCESTE software program were used to understand textual content. It was observed that social representations of work-related accidents in the health area are centered in the contamination category, while the categories of prevention and professional unpreparedness are found peripherally. There was a significant association between the existence of multiple employment, the use of personal protective equipment (PPI) during work, job satisfaction and the occurrence of work accidents. The conclusions indicate that perforating-cutting occupational accidents predominated in the hospital and that the representations of the subjects intertwined, with a traditional discourse of work accidents strongly present in Occupational Health. It is therefore suggested that certain subjective aspects related to culture, in terms of controlling work accidents, such as: management, process, organization and the increasing precariousness

Alcoolemia em vítimas fatais de acidentes de trânsito no Rio Grande do Norte empregando cromatografia em fase gasosa - head space

Alcohol is one of the few psychotropic drugs that their consumption has admitted legally and sometimes encouraged by the society. Studies show alcohol as the highest consumption of drugs among young people and society in general, probably because of its availability and easy access. The abuse causes public health problems, which was closely related to the violence, socioeconomic problems and the high number of automobile accidents. Transit is one of the main sectors affected by the effects of alcohol, observing a high incidence in the studies. About half of automobile accidents occurs after the consumption of alcoholic beverage, and the vast majority of cases related to high concentrations of alcohol in the bloodstream. The relationship of drunk with traffic accidents is in fact evident everywhere in the world, including Brazil, where studies have shown a high relationship between alcohol consumption and traffic accidents. This study determined the alcohol in fatal victims of traffic accidents in the state of Rio Grande do Norte and established the profile of this population compared with those found in Brazil and other countries. Samples of blood of ethanol added to fulfillment of the standardization of chromatographic conditions and procedures for the analysis, being employed in the determination of alcohol in blood samples of 277 victims of traffic accidents, collected at the Institute of Scientific Technical Police of Rio Grande do North (ITEP) in the year 2007. The blood alcohol level was determined in these samples correlated with the sex, age and marital status of the victim and the location, day of week and month when the accident occurred, is doing a statistical analysis and outlining a profile of the victims of an accident at transit in the state of Rio Grande do Norte. The parameters of standardization studied ensured the quality of the analytical method and, consequently, to obtain reliable laboratory results. Being given the best temperature for injector (150 ºC), detector (250 ºC) and column (50 ºC) with a flow of gas in the column of 2mL/minutos and analysis of time of 12 minutes. The method was linear in the range of 0.01 to 3.2 g / L (r2 = 0.9989) with average recovery of 100.2% and precision with coefficient of variation less than 15%. The analysis carried out on victims of fatal road traffic accidents, ethanol detected in the blood in 66.43% of the victims and these, 96% showed concentration ≥ 0.2 g / L, 87.73% of victims were male, while 12.27% female. The younger age group (1535 years) was the most involved (52,35%) and most single (55.60%). The accidents occurred with greater prevalence in the day on Monday (27%) followed by Sunday (24,19%) and Saturday (15,52%) and it was found that the prevalence of injuries varied between the different months of the year, and in February (14.4%) and April (10.47%) the months that had a higher number of accidents, however this oscillation showed no statistically significant difference. Also no significant difference was observed between the tracks of concentration found in men and women. The standardized method showed to be efficient, given satisfactorily to the goals of this work, and the high levels of alcohol found in victims of fatal road traffic accidents are consistent with several studies of literature, and the profile of the victim also supported by presenting in its most young adults, male and single

Aplicação de nanopartículas de quitosana com potencial de adjuvante na produção de soro contra o venneno do escorpião Tityus serrulatus

In Brazil, several species of scorpions are known to cause accidents which can lead to death, which are mainly belonging to the genus Tityus. The scorpion Tityus serrulatus is the main responsible for more severe cases. Anti-scorpion serums are routinely produced by various institutions, despite their effectiveness, quality and action depends on how quickly treatment is started. Studies have been developed in the search for appropriate technologies to encapsulate and release recombinant or natives proteins capable of inducing antibody production. In this context, chitosan copolymer which can be obtained from the partial deacetylation of chitin or in some microorganisms and it is biocompatible and biodegradable has been widely used for this purpose. This study aimed to search for a system release from chitosan nanoparticles for peptide / protein of the venom of the scorpion T. serrulatus, able to provide a new model of immunization in animals, in order to obtain a potential novel polyclonal serum, anti-venom T. serrulatus. The chitosan nanoparticles were prepared by ionic gelation with polyanion tripolyphosphate (TPP). After standardizing the concentrations of TPP and chitosan was evaluated the efficiency of incorporation of bovine serum albumin (BSA) and scorpion venom, showed particle size compatible with the intended purpose. The particles showed adequate size around 200nm. The crosslinking was confirmed by absorption spectroscopy in the infrared. After verified the high encapsulation efficiency (EE) for acid bicinconínico method (BCA) protein assay and the particle size distribution, the success of the technique was proven and the potential for in vivo application of nanoparticles. The experimental animals were vaccinated and the antibodies measured by ELISA

Folha de São Paulo: o diário oficial do grande irmão

This project wants to analyze the newspaper like a collective organic intellectual thing, and its action like a conservator integral journalism, it makes it looks like a politics block. In this case, the newspaper inserts itself in a process to support the dominated fundamental class. In the same time, it searches to disqualify politically, using the news and the opinion, the sprouting of against-hegemony even untimely and distant in the historical time. Facing this proposal we take as study object the FOLHA DE S. PAULO, nowadays the most representative agency of the great conservative press. Our theoretical reference takes as base the Gramsci organic intellectual formularizations, hegemony, position´s war, integral journalism and private device of hegemony. We allow ourselves, in a subsidiary way to the Gramsci basement, using the novel 1984 written by George Orwell, as a method to explicit, in a comparative way, the manipulation of the reality by the newspaper in its activity of collective organic intellectual. The ideology is the heuristic connection point to make convergence between reality and fiction. For the intended evidences we develop analysis of the daily covering about two great accidents occurred in 2007: The landslide of part of the workmanships of the tunnel of the Companhia do Metropolitano de São Paulo-Metrô (line yellow 4). And the flying disaster involving the airbus of Transportes Aéreos Meridionais-TAM, flight 3054, also in that state. In the first accident we find endorsement of the newspaper to the São Paulo´s government, in the person of the politician actor José Serra (PSDB), representative of the conservative forces and responsible for the workmanships of the Subway, to who it tried to distance politically of the fact. In the second event, the opposition to the politician actor Luis Inácio Luis Lula da Silva and his politics block, the PT, as a possibility against-hegemonic contested, being the mentioned actor appointed as responsible for the occurrence. However, the newspaper says that it is independent and direct, and this direct action comes from the environment. In this environment, the diversity of conceptions of world would guide the publishing work, making the FOLHA DE S. PAULO to take it as a reference for the intended objective, hiding the politics block militancy

Avaliação da gravidade do trauma em condutores de motocicleta vítimas de acidentes de trânsito no Rio Grande do Norte

Descriptive exploratory study, prospective, with quantitative approach, performed on the Monsenhor Walfredo Gurgel Hospital Complex (MWGHC), in Natal/RN, aiming to identify injuries by body area and wound severity on drivers who suffered motorcycle accidents, evaluate the severity of injuries and trauma on these drivers and identify the existence of association between wound and trauma severity and some of the accident s characteristics. The population comprised 371 motorcycle drivers, with data collected between October and December 2007. We used as instruments the Abberviated Injury Scale (AIS), Injury Severity Score (ISS) and the Glasgow Coma Scale (GCE1). The results show that, concerning characterization, there was a predominance of the male gender (88.4%), aged between 18 and 24 years (39.90%), originating from the Natal metropolitan region (55.79%), with fundamental-level instruction (51.48%), catholic (75.78%), married (47.98%). 23.18% work on commerce-related activities and 75.20% have income of up to 2 minimum wages. As for the accident s characteristics, the predominant shift was the afternoon (46.36%), received up to one hour after the event (50.67%), transported by countryside ambulances colleagues and relatives (51.21%), 25.34% had the accident on Sunday; 53.91% suffered falls and vehicle rolls; among the collisions there was a predominance of the motorcycle-automoblie type (28.03%); 52,6% were licensed and among these 50.76% had up to one year of license; 65.50% declared not having suffered previous accidents; 65.77% declared waring helmets in the time of the accident; 57.41% said not to have used drugs, and among those who used, alcohol was the most consumed (98.10%). The lowest score evaluated by GCS1 (3 to 8) was linked to drivers who suffered accidents on Saturday (10.3%), those who were not wearing helmets (14.29%) and the victims of motorcycle-pedestrian/animal crashes (13.33%). The body areas most affected had AIS between 1 and 3 (95.76%) and were: external surface (39.90%) and head/neck (33.20%). As for trauma severity, the highest scores (ISS>25) belonged to those who consumed alcohol (30.73%), suffered falls or vehicle rolls (48.9%) and those attended to 3 hours or longer after the accident (50%). We conclude that for motorcycle drivers who suffered accidents, age, gender, weekday, type of accident, use of drugs and the absence of helmet use signal both to the risk of occurrence of these events, as well as for the greater severity of injuries and trauma.
