Este é um relatório submetido como requisito parcial, para obtenção de grau de mestre em Engenharia Informática pela universidade da Madeira, em parceria com o Miti (Madeira Interactive Technologies Institute) e teve como base, o desenvolvimento de uma aplicação para equipamentos móveis com sistema operativo android. O objetivo principal foi, criar uma aplicação alternativa aos atuais sistemas existentes, para gestão e controlo de inspeções de segurança, efetuadas por funcionários de empresas de segurança privada (vigilantes) a instalações de clientes, atividade denominada por rondas. O principal problema encontrado e para o qual pretendia ser encontrada uma solução, não foi a falta de um sistema deste tipo, pois existem vários no mercado, mas sim, o elevado custo de aquisição dos atuais sistemas, aliado ao facto das suas limitações em termos de funcionalidades disponibilizadas tendo em conta esse elevado custo, e ainda a utilização de um equipamento dedicado e limitado exclusivamente a essa função. Conseguiu ser encontrada uma alternativa viável, versátil e prática, que para além de ser mais users friendly (termo utilizado para aplicações desenvolvidas tendo como foco o seu utilizador), disponibiliza aos seus utilizadores uma variedade de novas funcionalidades. Trata-se de uma alternativa muito mais económica mas igualmente eficaz, cumprindo assim o seu objetivo principal. Dadas as restrições temporais para o desenvolvimento deste projeto, são dadas no final deste documento, algumas ideias para uma possível evolução deste sistema, no sentido de o tornar ainda mais inovador.

This survey has to general objective to evaluate the Food Safety Policy implemented by Restaurantes Populares do Rio Grande do Norte. The survey is qualitative of type exploratory and descriptive. The universe of survey is all Units of Food and Nutrition (UAN) of the Restaurantes Populares do Rio Grande do Norte. To collects of data were used two instruments: interview and form. The interviews were intended to analyze the four axes of the Food Safety: access, food quality, production and marketing of food and organizational arrangement. The form was used to check the quality of nutrition and sanitary-hygienic food served. We used two types of forms: a spreadsheet with the weekly menu and the portions served to verify that the meals serve the nutritional needs proposed by the program; and the check-list of ANVISA to verify the sanitary-hygienic conditions in each unit. Through the survey data and analyses made observe that the access category have some problems such as lack of registration, lack of advertising of Restaurants and wastage of public resources, making policy that should be of included in a policy of exclusion. In the nutritional aspect there is neglect on the daily nutritional goal, because it is not accomplished nutritional analysis of menu offered, the nutritionists do not know what should be the nutritional value of meals served; in the hygienic-health aspect trough the problems identified is concludes that there is no guarantee of food quality hygienic-sanitary, committing the program as a Food Safety Program. About the production and marketing of food is observed some problems as: the goal of sale of meals is not achieved in full, the purchase of genres does not stimulate the local economy, nor generates jobs and income, and inefficient performance of the MEIOS's supervision. In the analysis of organizational arrangement is concluded that the partnerships are beneficial, despite some negative points, therefore, are these partnerships the problems of non-compliance, as both the MEIOS and Nutriti of important criteria established in the partnership. Therefore, it is understood that the Programa Restaurantes Populares in its original formulation is proposed to be a food safety policy, but has some problems that impossible to meet its goal, making it unprofitable like Food Safety Policy

This study examines the factors that influence public managers in the adoption of advanced practices related to Information Security Management. This research used, as the basis of assertions, Security Standard ISO 27001:2005 and theoretical model based on TAM (Technology Acceptance Model) from Venkatesh and Davis (2000). The method adopted was field research of national scope with participation of eighty public administrators from states of Brazil, all of them managers and planners of state governments. The approach was quantitative and research methods were descriptive statistics, factor analysis and multiple linear regression for data analysis. The survey results showed correlation between the constructs of the TAM model (ease of use, perceptions of value, attitude and intention to use) and agreement with the assertions made in accordance with ISO 27001, showing that these factors influence the managers in adoption of such practices. On the other independent variables of the model (organizational profile, demographic profile and managers behavior) no significant correlation was identified with the assertions of the same standard, witch means the need for expansion researches using such constructs. It is hoped that this study may contribute positively to the progress on discussions about Information Security Management, Adoption of Safety Standards and Technology Acceptance Model

The evaluation of public policies that promote Food Security and Nutrition (FSN) it s a multidisciplinary activity extremely relevant to the effectiveness of actions to legitimize the Human Right to Adequate Food (HRAF). This study aimed at assessing the effectiveness of the unit project Natal-RN Café do Trabalhador in promoting SAN to its users. The theoretical framework is based on the public and political and on the dimensions of the concept of FSN (quantity and quality-regularity). Through a qualitative approach, methodologically this was the work of an evaluation of efficiency of the unit Natal-RN of Café do Trabalhador project in light of the assumptions of the concept of SAN. Data collection was conducted through retrospective archival research in official documents of the project, semi-structured interviews with managers involved in its implementation (representative of the Secretary of State for Employment, Housing and Care of RN SETHAS and third party), socioeconomic questionnaire applied to the users of the unit, check the amount, regularity and quality of meals offered for 15 days (menu routine) using the descriptive form menu and form filling type checklist for verification of compliance with good practices . Methods of analysis, we used content analysis, descriptive statistics and compared to previously established parameters for the project. As categories of analysis were defined organizational arrangement, access, user, food quantity-regularity and food quality. The results show that, it was found in the category arrangement that will implement the project dismissed technical criteria for choosing the districts and the quantitative distribution of meals for each location. It was found that the valuation of the shares of the company outsources technical SETHA has not been performed. We observed in the access category, the unit has a strategic location, but lack of space in the refectory. The main obstacle to economic access for users is the lack of a register for the beneficiaries. In the category of users, it was identified that the clientele of the project it is predominantly men, with more than 51 years, low education, earning wages less 1 obtained through informal employment, which they move up through the unit transport collective, go to all days of operation due primarily to price. About the meals category quantity-regularity of food showed that the menu serves 95% of the desired needs, and that holidays and weekends are periods of disrupting the regularity of supply of meals. Regarding the category of food quality, it was found that the nutritional aspect on the menu are food sources rich in sodium, nitrates and low in fiber. In the aspect of hygiene and sanitation are the main limitations related to waste management, lack of exposure controls of food prepared and inadequacies of the physical structure. The results showed that in general and the institutional arrangement of the organs attached to the project should establish a systematic evaluation project is to establish as a promoter of and FSN overcome these obstacles

The research aimed to understand the challenges for the implementation of the proposed integration between the Civil Police and the Military Police in Rio Grande do Norte to the proposals of the SUSP. This study aimed to explore the gap with regard to the deepening of the possible causes that may hinder the implementation of integrated working between the police in public security, through a specific analysis on the state of Rio Grande do Norte. Was based on a theoretical framework that includes policies: general concepts, the steps of a public policy, the implementation stage , public security : conceptual definitions, policies on security in Brazil, the structure of public security in Brazil and systems police, Military Police x Civil Police: Roles and conflicts , integrating public security: the challenges to be overcome, the Unified public Safety (SUSP) and the main difficulties in the integration of the police. Being classified as to the purposes as an exploratory research on how to approach ranks as qualitative. The research unit was the Center for Integrated Operations Public Safety (CIOSP) through three subjects who were the chief CIOSP, the representative of the military police acting with the CIOSP, and representative civil police also active with the CIOSP. These subjects were chosen because of the understanding that individuals occupying senior positions would have more ability to respond to questions that guide the research problem. Data were collected through a set of interviews, qualitative data analysis was performed based content analysis, based on the definition of categories of analysis, gated time cross. With the results, it was revealed that the main problems of integration between the state police are treatment protocols, lack of political will and lack of infrastructure. The relationship between the Military Police and Civil Police in Rio Grande do Norte has differing cultural aspect, but can be considered as good value, professionalism and integrated operations. The implementation of CIOSP-RN followed the characteristics of the top-down model, the main difficulties in implementing the proposals of the SUSP, lack of own resources, the lack of standardization in public safety and the lack of professional training of public safety. It was concluded that with respect to the challenges to the implementation of the proposed integration between the Civil Police and the Military Police in Rio Grande do Norte to the proposals of the SUSP, the actions follow the characteristics of the top-down model, with no autonomy of administrators public to say in decisions, which restricts the view of the public safety of the state

João Pessoa, the capital city of the state of Paraíba (Northeast Brazil), is reputed throughout the country as a quiet place, although it has been acquiring, over the past years, an urban character with social implications similar to those of major metropolitan Brazilian areas. The new situation is evident by the social inequalities, with the creation of confined spaces, which segregate and cause enclosure of the inhabitants, leading to death the public space. This study correlates accessibility in spatial structure with two types of crime data, burglary and robbery, recorded in 2008 and 2009, by the Secretaria de Segurança da Paraíba (The government agency public in charge of safety), in the district of Manaíra, an upper middle class neighborhood, which has, in recent times, been considered one of the most violent areas in João Pessoa. Sought to understand connections between these events and morpho-social aspects of the built environment, where examined the spatial properties, such as accessibility of the urban net, the presence of control measures, the safety of buildings and their uses. Spatial properties were also validated by the observation of pedestrian flows at strategic points of the study area. It was concluded that the presence of intense flows helps to attract potential thieves, physical security and control offers little protection

In the operational context of industrial processes, alarm, by definition, is a warning to the operator that an action with limited time to run is required, while the event is a change of state information, which does not require action by the operator, therefore should not be advertised, and only stored for analysis of maintenance, incidents and used for signaling / monitoring (EEMUA, 2007). However, alarms and events are often confused and improperly configured similarly by developers of automation systems. This practice results in a high amount of pseudo-alarms during the operation of industrial processes. The high number of alarms is a major obstacle to improving operational efficiency, making it difficult to identify problems and increasing the time to respond to abnormalities. The main consequences of this scenario are the increased risk to personal safety, facilities, environment deterioration and loss of production. The aim of this paper is to present a philosophy for setting up a system of supervision and control, developed with the aim of reducing the amount of pseudo-alarms and increase reliability of the information that the system provides. A real case study was conducted in the automation system of the offshore production of hydrocarbons from Petrobras in Rio Grande do Norte, in order to validate the application of this new methodology. The work followed the premises of the tool presented in ISA SP18.2. 2009, called "life cycle alarm . After the implementation of methodology there was a significant reduction in the number of alarms

This dissertation aims to understand the importance of the National School Feeding as a strategy for ensuring the promotion of food and nutrition security in the municipality of Macaíba / RN, taking into account the implementation of the Law School Feeding, 11,947, 2009. The program was extended to all public basic education, youth and adults, in addition to ensuring that 30% of transfers from FNDE, were intended for the purchase of products from family farms. The survey was conducted with 160 students from public schools and farmers nesting Quilombo dos Palmares II, who produce on their land vegetables, fruits and cereals for their own consumption, for sale in local markets, in addition to providing for PNAE. The reciprocity between neighbors, such as mutual aid and sharing of common goods was noticeable in this group of farmers, since it was necessary to meet weekly deliveries of products to schools. As students, we applied a test of acceptability in two schools located in rural and in urban areas, to learn the opinion of ourselves in relation to school food consumed. It was concluded that to be most effective program in the region, there must be a better match in school menus, so that it can be attractive to students and to ensure greater use of fresh food, the main ingredient of same, practice of nutrition education in schools, to teach students the importance of food to health. In relation to local management, noted the need for adjustments bureaucratic as hiring staff for the departments, in order to be more agile in releasing payments to farmers, in addition to hiring assistants general services for schools, one Since the cooks exert dual role, the cooking while being responsible for cleaning the entire school environment. Government investments in the rural sector would be extremely valuable for farmers, since they need financial resources to purchase inputs, irrigation projects for gardens, availability of land for planting, transportation to facilitate the delivery of its products to schools and technical assistance more frequently

It is been a great deal of interest the studying of the operational performance of tractors and its machinery especially in work conditions. The present study had as objective to evaluate the operational performance of an Aerossolo prototype tracked with a Valtra BM100 4x2 TDA, with the engine power of 73.6 kW (100 cv). The prototype equipment is a drag type, hydraulically commanded, with telescopic heading for longitudinal adjustment, two lateral sections with 28 knifes in each one of them, concrete ballasts, wheels of transport and aggregate breaker coil. The work was conducted in the Department of Agricultural Engineering of the UNESP, Jaboticabal Campus, in a randomized blocks design, factorial 3 x 3, with four repetitions. The nine studied treatments were a combination for three ballast conditions (0; 960 and 1,307 kg) and three angles of the sections (0 degrees; 7 degrees and 14 degrees). The results indicate an increase in operational consumption (liters per hectare) of 32.4% in relation to the concrete ballast addition, and a 26.8% in relation to the angle variation between sections. The working depth, traction force and power demands were higher with the increases in the concrete ballast and the angle variation between sections.

O tema proposto nesta tese vai ao encontro do atual debate em curso no Brasil e no mundo acerca de duas dimensões da cadeia agroalimentar: produção e consumo. Desse modo, as questões de como se dá essa relação frente às estratégias locais por diferentes atores, terá ênfase. Para isso, como campo empírico foram escolhidos três municípios localizados no território Centro-Sul do estado do Paraná: Irati, Inácio Martins e Fernandes Pinheiro que desde 2004 estão inseridos no Programa de Aquisição de Alimentos (PAA), mais especificamente na modalidade Compra com Doação Simultânea (CDS). A hipótese que embasa este estudo é de que o PAA poderá ser capaz de assumir um caráter estruturante - a partir do seu viés pedagógico, capacidade organizativa de produção, manutenção da diversidade ou resgate da policultura (e aqui se privilegia a agroecologia), bem como uma alternativa viável de acesso a um tipo de mercado (mercado institucional) -, não por altruísmo dos atores, mas por ser mais vantajoso ser parte integrante, do que estar à parte do processo, aliando a isso melhorias nas condições alimentares tanto das suas famílias, quanto das entidades receptoras. O objetivo principal foi analisar as relações sociais e as práticas alimentares de um grupo de agricultores(as) agroecológicos entre as responsáveis pelo recebimento dos alimentos doados buscando compreender se o PAA possibilita a Soberania e Segurança Alimentar e Nutricional (SSAN) de grupos sociais (como das famílias rurais) e das pessoas atendidas por estas entidades. A metodologia utilizada foi a de estudo de caso. Como procedimentos foram empregados entrevistas semi-estruturadas e aplicação de questionários como: Escala Brasileira de Insegurança Alimentar(EBIA) e Questionário de Frequência de Consumo Alimentar(QFCA). A amostra foi composta por agricultores(as)/ fornecedores(as) do PAA, nutricionistas e, coordenadora de uma das entidade dos seus produtos é, de fato, o que os mobiliza a continuar produzindo em maior diversidade e quantidade. Após a vivência dos(as) agricultores(as) /fornecedores de estarem inseridos no Programa foi possível para estes atores se sentirem parte do processo e, assim, repensar suas práticas de produção de alimentos, seja ela destinada ao autoconsumo, seja voltada à comercialização. Para além da discussão acerca da produção destinada ao autoconsumo, ficou claro o processo de recampesinização entre as famílias de agricultores(as). O processo de (re)conexão se apresenta de forma frágil, considerando, sobretudo, as considerações feitas pelas mediadoras. Trazer à tona o debate acerca da produção-consumo de alimentos, tanto na perspectiva de quem produz, como na de quem consome, e tomando por referência a operacionalização de políticas públicas, viabiliza a ampliação de debates e a concretização de ações mais contundentes numa perspectiva de minorar a situação de vulnerabilidade (social e alimentar) e de pobreza rural

The subject of public safety is part of the academic and popular discussions, due to several factors that act in society culminating in an increasing criminality. The importance of the evaluation of public policies in this context consists in a possible control tool, monitoring and necessary adjustments to the government to make the necessary changes. Given this reality, it is thought the research problem: how Mossoró (RN) city has implemented his public security policy? In general guideline of the research, we work with the following hypothesis: the own formulation of the National Policy of Public Safety there are elements that hinder the implementation of a public policy of municipal security in Mossoró. The objective of this research is to evaluate the existing security public policy in the city of Mossoró, by the elements that facilitate and/or hamper its implementation, through the actions of municipal government in the activities of the Mossoro Civil Guard (GCM). For this, a review of the implementation process was conducted, specifically its subprocesses of selection, training, and logistical or operational. Was used bibliographical research, documental primary and secondary, and field research, with conducting of interviews. It was found that with a staff of 197 guards, and with five years of creation, the actions developed by this institution refer to an early implementation of the municipal security policy. The guard has the basic pattern selection, part of function relocation and part of public tender. The formation occurs in an introductory way, however, not complete and specific, for the function performance. Its operability is limited by the number of existing effective and by the physical structure that has not matching the demand yet, which touches on the municipal budgetary reality of direct resource intended to safety. It was found the absence of a municipal plan of public security with principles, guidelines and goals that could direct the actions of the guard. It is concluded that despite of the implementation of the GCM Mossoró have not achieved, within the parameters of efficiency, efficacy and effectiveness have played their actions, projects and programs, it could trigger a process of opening for construction of a municipal security policy. As well as break with the paradigm of municipal actions just meant for surveillance of public property, interaction affirmative for the prevention of violence and crime

Os objetivos deste trabalho foram quantificar as exposições dérmicas (EDs) e respiratórias (ERs) proporcionadas ao piloto e ao seu ajudante nas aplicações de herbicidas para o controle de plantas daninhas aquáticas com aerobarco; classificar essas condições de trabalho em seguras ou inseguras; e calcular a necessidade de controle das exposições (NCE) e o tempo de trabalho seguro (TTS). O aerobarco utilizado tinha casco de alumínio (4,85 x 2,42 m) e acionamento por hélice acoplada a motor a gasolina de 350 HP. O equipamento de pulverização era composto por bomba de diafragma com fluxo máximo de 49,69 L min-1, pressão máxima de 25 kg cm-2, acionada por motor a gasolina de 4 HP, e tanque de calda de 189 L. A barra de pulverização de alumínio era composta de duas seções laterais de 3 m, posicionadas na linha entre o encosto do banco do piloto e o início da estrutura protetora da hélice. Cada seção da barra tinha seis bicos com pontas de jato plano com indução de ar AI 100 03, espaçados de 0,5 m, e uma ponta OC 20 fixada em cada extremidade. O conjunto de pontas pulverizava faixas de 6 m de largura e aplicava o volume de calda de 200 L ha-1. O sistema tinha gerenciador de fluxo, controlado por central eletrônica acoplada a DGPS (com precisão submétrica), para corrigir automaticamente a vazão em função de alterações na velocidade real da embarcação. As EDs e ERs aos herbicidas foram calculadas com os dados substitutos das exposições às caldas, avaliadas com os traçadores cobre e manganês adicionados às caldas. As exposições foram extrapoladas para uma jornada de trabalho de seis horas. A segurança das condições de trabalho foi determinada com o cálculo da margem de segurança (MS), utilizando-se a fórmula MS = (NOEL x 70)/(QAE x 10), em que QAE = quantidade absorvível da exposição. As condições de trabalho foram classificadas em seguras, se MS>1, ou inseguras, se MS<1. As exposições proporcionadas pelas condições de trabalho foram de 10,65 mL de calda por dia para o piloto e de 16,80 mL por dia para o ajudante, que fica sentado em uma cadeira a 2,0 m à frente do piloto e da barra de pulverização. Classificaram-se como seguras as aplicações dos herbicidas glyphosate (Rodeo, 6 L ha-1), 2,4D (DMA 806 BR, 8 L ha-1) e fluridone (Sonar AQ, 0,4 L ha-1), para o piloto e o seu ajudante. Classificou-se como insegura a aplicação do herbicida diquat (Reward, 4,0 L ha-1) para as duas condições de trabalho, cujas necessidades de controle das exposições calculadas foram de 65% para o piloto e de 78% para o ajudante do piloto.

O objetivo deste trabalho foi avaliar os efeitos do período e volume de aplicação na segurança da atividade de tratoristas aplicando herbicidas na cultura de cana-de-açúcar com o pulverizador de barra montado em trator e a eficiência de equipamentos de proteção individual (EPIs) e de uma cabina acoplada ao trator. As exposições dérmicas de 13 condições de trabalho foram avaliadas e analisadas estatisticamente por meio do delineamento inteiramente ao acaso e do esquema fatorial 3 x 2 x 2 + 1. O fator A foi a condição de exposição: 1) exposição dérmica potencial (EDP) - sem nenhuma medida de segurança; 2) exposição com cabina no trator (Cabina); e 3) exposição com as vestimentas (EPI). O fator B foi o volume de aplicação: 1) 200 L ha-1 e 2) 100 L ha-1; e o fator C foi o período de aplicação: 1) diurno e 2) noturno. Como testemunha foi avaliada a EDP do tratorista aplicando na atividade usual de 300 L de calda ha-1, no período diurno. As exposições dérmicas (EDs) aos herbicidas considerados nessas condições de trabalho foram estimadas por meio de dados substitutos das EDs avaliadas ao cátion Cu+2 adicionado como traçador nas caldas aplicadas. O pulverizador utilizado foi do modelo PJ 600, com barra de 12 m de comprimento e 24 bicos de jato plano TT 110 04 ou TT 110 02. As 13 condições de trabalho avaliadas foram classificadas como seguras (MS>1) para o tratorista aplicando os herbicidas glyphosate (48% i.a.), MSMA (48%), diuron (46,8%) + hexazinone (13,2%), clomazone (50%), sulfentrazone (50%), ametryne (50%), diuron (50%), isoxaflutole (75%), metribuzin (48%), 2,4-D (80,6%), ametryne (30%) + clomazone (20%), ametryne (73,25%) + trifloxysulfuron (1,85%) e tebuthiuron (80 %) e inseguras para o herbicida atrazine (50%), nos dois períodos e nos três volumes de aplicação, e ametryne (50%), na aplicação diurna e 100 L de calda ha-1. As aplicações noturnas e os volumes de aplicação reduzidos tornaram as condições de trabalho mais seguras, exceto para o atrazine. A eficiência dos EPIs para a aplicação de 300 L ha-1 variou de 69,5 a 89,3%, e a da cabina do trator variou entre 76,4 e 83,3%, em relação aos volumes reduzidos de 100 e 200 L ha-1.
