The present work has an objective of investigate the acceptability of consumption of the goat meat and studies the perception of university students on the productive sector of goats in the Northeast. The habit to eat goat meat has strong regional traditions and has been suffering the demographic, cultural, economic and personal influences. Currently, a new habit in the food consumers is observed and has been configuring itself a trend that concern with the health and welfare in general, in countries mainly developed. This fact comes directly contributing for the modernization of the production models, including the ambient conscience. The methodology applied includes bibliographical research, data-collecting through questionnaires applied in the UFRN (Federal University of Rio Grande do Norte ) and analysis of the data using statistic techniques assisted for software Statistica V6. It is concluded that the rate of consumption of goat meat is low in the population studied. The frequency of consumption is higher in times of leisure or to visit relatives. The descriptive analysis of the responses of interviewees shows ignorance of the production of goat meat and its importance to the state of Rio Grande do Norte.

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.

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

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)

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.

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

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

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

Com o objetivo de estudar o efeito da restrição alimentar sobre as características da carcaça de caprinos leiteiros, realizou-se um experimento utilizando 27 cabritos castrados da raça Saanen. Os animais (PV inicial de 20 kg) foram distribuídos nos tratamentos alimentação à vontade e 30 e 60% de restrição, sendo abatidos aos 35 kg de PV. Foram avaliados o rendimento comercial e biológico, os cortes comerciais, a área de olho-de-lombo e a composição tecidual da perna. O rendimento biológico não foi afetado pela restrição alimentar, mas o comercial diminuiu com o aumento da restrição. A elevação no nível de restrição alimentar promoveu diminuição do lombo e da 6ª a 13ª costelas e aumento da paleta e do pescoço, proporcionalmente à meia-carcaça. A proporção de ossos aumentou e a de gordura total diminuiu com o aumento da restrição. O tecido muscular não foi afetado pela restrição. A restrição alimentar de até 30% não prejudicou a qualidade da carcaça de caprinos leiteiros.

Foram utilizados 60 suínos machos castrados (89,1 ± 4,2 kg) para avaliar o uso de níveis (0, 5, 10, 15 e 20%) de restrição qualitativa, resultando em valores de 3.407, 3.240, 3.060, 2.890 e 2.720 kcal de energia digestível por quilo de ração. Dez animais foram abatidos no início do experimento para determinação da composição corporal inicial, enquanto os demais foram alimentados com as dietas experimentais até atingirem 128 kg. Utilizou-se o delineamento em blocos casualizados para controle das diferenças de peso inicial, com dez blocos, cinco tratamentos (dietas experimentais) e um animal por unidade experimental. Dados de características de desempenho, de carcaça e parâmetros séricos dos animais foram submetidos à análise de variância com posterior desdobramento em regressão em função dos níveis de restrição qualitativa das dietas. O aumento nos níveis de restrição qualitativa não alterou o consumo diário de ração, mas reduziu linearmente o consumo diário de energia digestível e o ganho diário de peso, piorando a conversão alimentar e melhorando a eficiência de utilização de energia pelos animais. Os níveis de restrição qualitativa provocaram redução linear dos níveis séricos de triacilgliceróis e da espessura de toucinho e aumento da porcentagem e quantidade de carne magra e do índice de bonificação das carcaças, mas não alteraram o ganho diário de carne magra. A utilização de restrição qualitativa é eficiente para reduzir a ingestão energética e a deposição de gordura em suínos não reduz a capacidade de produção de carne magra.

Objetivou-se com este trabalho avaliar o efeito da restrição alimentar nas características de carcaça de cabritos F1 Boer x Saanen. Foram utilizados 21 cabritos, pesando 15 kg de PV, distribuídos em três tratamentos (0, 30 e 60% de restrição). O consumo dos animais do tratamento 0% de restrição determinavam o consumo dos animais dos tratamentos 30 e 60% de restrição. Quando os animais do nível de restrição 0% atingiam 25 kg, estes juntamente com seus pares foram submetidos a jejum de sólido de 24 h e de líquido de 16 h. O abate ocorreu mediante descarga elétrica, seguido de sangria e retirada dos órgãos. Os ganhos de peso foram de 211,03, 126,15 e 11,71g/dia; a eficiência alimentar de 0,20, 0,18 e de 0,03; os pesos de abate de 25,44, 20,91 e 15,82kg para os tratamentos 0, 30 e 60% de restrição, respectivamente. O rendimento de carcaça quente, de carcaça fria e biológico não foram influenciados pela restrição alimentar. Somente a proporção da paleta e a do lombo foram influenciados pela restrição alimentar, com aumento linear do rendimento da paleta e decréscimo linear do rendimento do lombo. Houve efeito da restrição na redução do rendimento de gordura e aumento da proporção de osso. A restrição alimentar em níveis moderados, permitiu a obtenção de carcaças de boa qualidade, com bom rendimento, elevada proporção de músculo e baixa participação de gordura e, dependendo da relação custo:benefício, pode tornar-se boa alternativa para o produtor.

O objetivo neste trabalho foi avaliar economicamente o uso da restrição alimentar qualitativa para suínos machos castrados em terminação sobre o desempenho e as características de carcaça de 60 animais. Dez suínos foram abatidos no início da fase experimental (89,0 ± 4,2 kg) e os demais, alimentados com rações contendo cinco níveis de restrição nutricional qualitativa (0, 5, 10, 15 e 20%), obtidas pela inclusão de casca de arroz finamente moída, até o final do experimento (127,8 ± 2,9 kg). Foram calculados os custos com alimentação durante o período experimental (R$alimento) e estimados os valores de receita bruta de cada carcaça de animais abatidos aos 128 kg (RBsuíno128kg) ou no início do experimento (RBmédia_suíno89kg). A partir destes três dados, foi calculado o resultado líquido (RL) do uso das dietas experimentais (RL = RBsuíno128kg - RBmédia_suíno89kg - R$alimento). Também foram analisadas as variações mensais dos preços do milho, do farelo de soja e do suíno, sendo determinado o preço do milho como o fator de maior impacto sobre a lucratividade do uso da restrição qualitativa. A equação de predição da probabilidade de aumento linear do resultado líquido pelo uso da restrição qualitativa foi determinada em função dos diferentes preços do milho - PM (valor de P RL = 0,392 - 0,625PM, R² = 0,73). Efeito significativo foi observado para preços do milho de cerca de quatro vezes ou mais acima do custo da casca de arroz. Assim, conclui-se que a viabilidade do uso da restrição qualitativa, até o nível de 20%, depende do cenário econômico, mas sobretudo do preço do milho, o principal ingrediente substituído nas rações ao empregar-se a restrição qualitativa, e de sua relação com o custo do resíduo utilizado para diluição energética.

Previous works have studied the characteristics and peculiarities of P2P networks, especially security information aspects. Most works, in some way, deal with the sharing of resources and, in particular, the storage of files. This work complements previous studies and adds new definitions relating to this kind of systems. A system for safe storage of files (SAS-P2P) was specified and built, based on P2P technology, using the JXTA platform. This system uses standard X.509 and PKCS # 12 digital certificates, issued and managed by a public key infrastructure, which was also specified and developed based on P2P technology (PKIX-P2P). The information is stored in a special file with XML format which is especially prepared, facilitating handling and interoperability among applications. The intention of developing the SAS-P2P system was to offer a complementary service for Giga Natal network users, through which the participants in this network can collaboratively build a shared storage area, with important security features such as availability, confidentiality, authenticity and fault tolerance. Besides the specification, development of prototypes and testing of the SAS-P2P system, tests of the PKIX-P2P Manager module were also performed, in order to determine its fault tolerance and the effective calculation of the reputation of the certifying authorities participating in the system
