Eosi: um modelo para desenvolvimento de sistemas embarcados tolerantes a falhas

The semiconductor technologies evolutions leads devices to be developed with higher processing capability. Thus, those components have been used widely in more fields. Many industrial environment such as: oils, mines, automotives and hospitals are frequently using those devices on theirs process. Those industries activities are direct related to environment and health safe. So, it is quite important that those systems have extra safe features yield more reliability, safe and availability. The reference model eOSI that will be presented by this work is aimed to allow the development of systems under a new view perspective which can improve and make simpler the choice of strategies for fault tolerant. As a way to validate the model na architecture FPGA-based was developed.

Um estudo da aplicação do conceito de risco na conscientização e conhecimento de estudantes de ensino técnico sobre riscos de segurança e saúde ocupacional em laboratório de soldagem

This dissertation presents a discussion on the level of risk awareness of students who have welding practice in the laboratories at CEFET/PI, both in Teresina and Floriano. Its main goal is to investigate risk factors involving students, teachers and employees that work in these laboratories. It s an empirical survey, held among a certain amount of students from the course in Mechanic Technology. For data analysis, the concept of risk was compared to the students direct measure of perception. The main results suggest the students must be better informed, more risk aware and more competent, in order to avoid accidents. They also point to a strong need for a more formal and effective performance to assure full consciousness about the risks involving the welding practice.

Segurança Alimentar e Controle de Qualidade: um estudo da implantação do Programa Alimentos Seguros em supermercados de bairro

This study aimed to analyze the percentage of compliance, related to the requirements of Practice, achieved by 23 supermarkets in neighborhood after the deployment of Food Insurance Program. For its development research methodology adopted was the application start and end of a check-list (tool-specific SBP) in 23 supermarkets, target of this study. After the deployment of PAS was made a comparative study where it was possible to see that these companies need to improve conditions related to food safety, because according to the study, none of the 23 supermarkets evaluated met the criteria recommended by the SBP to 100% of compliance for the items critical of the check-list. Only 04 of the 23 supermarkets were in the range of 80 to 90% of the overall percentage of compliance, representing only 17.3% of the sample. Most of the sample submitted in a regular situation, according to the methodology of Cardoso (2001). Of the 23 supermarkets studied, 03 supermarkets were classified as poor (13.04%), 13 as scheduled (56.52%) as good and 07 (30.43%). You can see improvements in a small part of the sample, but the decline in the percentage of compliance of 02 companies after working for the implementation of the program, showing lack of responsibility and commitment of companies which should have as its top priority to food safety that market

Melhoria da segurança pública: uma proposta para alocação de unidades policiais utilizando o modelo das p-medianas e do caixeiro viajante

The decrease in crime is one of the core issues that cause concern in society today. This study aims to propose improvements to public safety from the choice of points to the location of police units, ie the points which support the car and the police. For this, three models were developed in order to assist decision making regarding the best placement of these bases. The Model of Police Units Routing has the intention to analyze the current configuration of a given region and develop optimal routes for round preventative. The Model of Allocation and Routing for New Police Units (MARNUP) used the model of facility location called p-median weighted and traveling salesman problem (TSP) combined aiming an ideal setting for regions that do not yet have support points or to assess how far the distribution is present in relation to that found in solution. The Model Redefinition and Routing Unit Police (MRRUP) seek to change the current positioning taking into account the budgetary constraints of the decision maker. To verify the applicability of these models we used data from 602 points to instances of police command that is responsible for the capital city of Natal. The city currently has 31 police units for 36 of these 19 districts and police have some assistance. This reality can lead to higher costs and higher response times for answering emergency calls. The results of the models showed that in an ideal situation it is possible to define a distance of 500 km/round, whereas in this 900 km are covered by approximately round. However, a change from three-point lead reduced to 700 km / round which represents a decrease of 22% in the route. This reduction should help improve response time to emergency care, improving the level of service provided by the increase of solved cases, reducing police shifts and routing preventive patrols

Um estudo do perfil de formação dos técnicos de segurança do trabalho no Brasil na perspectiva de sistemas de gestão de segurança e saúde ocupacional

This work provides great contribution to the documental study of the Work Safety courses offered by CEFETs in Brazil, under the perspective of safety management and occupational health, using as a referential the specification OHSAS 18001 (BSI, 1999), as well as directions provided by OIT (ILO, 2001). The theoretical research compares technical and managing competences of the projects of Work Safety courses at CEFETs with the international legislation mentioned above. For field research, questionnaires containing open and close questions were answered by teachers and students aiming at identifying the importance of technical and managing competences for the formation of Work Safety technicians, besides trying to identify which level of minimal formal knowledge should be required to perform managing activities in the area of Work Safety Management Systems and Occupational Health (SGSSO, in Portuguese). The results of the theoretical research point out differences between the projects of the Work Safety technical courses at CEFETs under the perspective of SGSSO. The field research shows that students and teachers opinions converge about most technical and managing competences. In relation to academic formation, the research suggests divergences to the criterion stated by the norm ISO 19011(ABNT, 2002)

Modelagem de arranjos institucionais para implementação da diretriz de sistema de gestão de segurança e saúde ocupacional da organização internacional do trabalho ILO/OSH 2001 no brasil

The commitment assumed by Brazil to ILO in order to pursue actions toward the ILO/OSH-2001 adoption in the country poses the issue of modeling the institutional arrangement the set roles and relationship between government, standards organizations, health and safety organizations, professionals and other institutions to deploy the ILO/OSH-2001. This Thesis develop institutional arrangement models based on the current model and also in the ISO 9000 scheme and others. It is studied the US case with OSHA and VPP, the OHSAS 18001 and ANSI/AIHA Z-10, in addition to actual context of the regulating norms NR s. The scenarios developed are put to evaluation on feasibility, potential changes and effects on current MTE auditors work scheme. The main results are five scenarios developed and that the MTE auditors tend to be reactive to the change toward the ILO/OSH-2001.

Uma contribuição à reformulação da norma regulamentadora 13 (NR-13) na perspectiva da adoção de sistema de gestão de segurança e saúde ocupacional

This Master s Thesis deals with an analysis of the Regulatory Standards NR-9 e NR-13 on the perspective of occupational health and safety management systems (OHSMS) such as ILO deployed ILO/OSH-2001. Since the revamped OHSAS 18001:2007 complies with the ILO/OSH-2001 model it is used as benchmark to compare against the NR-9 and NR-13. The analysis suggests that the NR-9 has some important features present on the OHSAS 18001:2007 but lacks important others. The NR-13 turns out to be far from a modern model of OHSMS such as OHSAS 18001:2007 and a deep reformulation should be done in order to achieve the Brazil commitment with ILO to adopt OHSMS. Also, a small survey with companies with ISO 9000 certificates suggests that a NR-13 revised toward OHSMS would be welcome, but also that some more advanced issues present in ILO/OSH-2001 should be imposed by law in order to be achieved

Fatores influenciadores da implementação de ações de gestão de segurança da informação :um estudo com executivos e gerentes de tecnologia da informação das empresas do Rio Grande do Norte

Information is one of the most valuable organization s assets, mainly on a global and highly competitive world. On this scenery there are two antagonists forces: on one side, organizations struggle for keeping protected its information, specially those considered as strategic, on the other side, the invaders, leaded by innumerous reasons - such as hobby, challenge or one single protest with the intention of capturing and corrupting the information of other organizations. This thesis presents the descriptive results of one research that had as its main objective to identify which variables influence the Executives´ and CIOs´ perceptions toward Information Security. In addition, the research also identified the profile of Rio Grande do Norte s organizations and its Executives/CIOs concerning Information Security, computed the level of agreement of the respondents according to NBR ISO/IEC 17799 (Information technology Code of practice for information security management) on its dimension Access Control. The research was based on a model, which took into account the following variables: origin of the organization s capital, sector of production, number of PCs networked, number of employees with rights to network, number of attacks suffered by the organizations, respondent´s positions, education level, literacy on Information Technology and specific training on network. In the goal´s point of view, the research was classified as exploratory and descriptive, and, in relation of the approach, quantitative. One questionnaire was applied on 33 Executives and CIOs of the 50 Rio Grande do Norte s organizations that collected the highest taxes of ICMS - Imposto sobre Circulação de Mercadorias on 2000. After the data collecting, cluster analysis and chi-square statistical tools were used for data analysis. The research made clear that the Executives and CIOs of Rio Grande do Norte s organizations have low level of agreement concerning the rules of the NBR ISO/IEC 17799. It also made evident that the Executives and CIOs have its perception toward Information Security influenced by the number of PCs networked and by the number of attacks suffered by the organizations

Segurança da informação no correio eletrônico com base na ISO/IEC 17799 :um estudo de caso em uma instituição superior com foco no treinamento

The electronic mail service is one of the most Internet services that grow in the corporate environment. This evolution is bringing several problems for the organizations, especially to information that circulates inside of the corporate net. The lack of correct orientation to the people, about the usage and the security importance of these resources, is leaving breaches and causing misusage and overuse of service, for example. In recent literature, it starts to coming out several ideas, which has helped to rganizations how to plain and how to implement the information security system to the electronic mail in computer environment. However, these ideas are still not placed in practice in many companies, public or private. This dissertation tries to demonstrate the results of a research that has like goal, identify the importance that user training has over the information security policy, through a case study inside of private superior education institute in this state. Besides, this work had by basic orientation the ISO/IEC 17799, which talk about People Security. This study was developed over a proposed model to this research, which looked for offer conditions to guide the institution studied, how to plan better a information security policy to the electronic mail. Also, this research has an exploratory and descreptive nature and your type, qualitative. Firstly, it was applied na questionary to the information technology manager, as better way to get some general data and to deepen the contact which still then, it was being kept through e-mail. Thereupon this first contact, eleven interviews were done with the same manager, beside one interview with twenty-four users, among employees e students. After that to collect and transcript the interviews, were review with the manager all informations given, to correct any mistakes and to update that informations, to then, start the data analyze. The research suggests that the institution has a pro attitude about the information security policy and the electronic mail usage. However, it was clear that answers have their perception about information security under a very inexperient way, derived of a planning lack in relation to training program capable to solve the problem
