Sistema de gestão de rondas: aplicação android para empresas de segurança privada

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.

Aspectos do gerenciamento de riscos de tecnologia da informação nas empresas: um estudo de caso múltiplos

The information technology - IT- benefits have been more perceived during the last decades. Both IT and business managers are dealing with subjects like governance, IT-Business alignment, information security and others on their top priorities. Talking about governance, specifically, managers are facing it with a technical approach, that gives emphasis on protection against invasions, antivirus systems, access controls and others technical issues. The IT risk management, commonly, is faced under this approach, that means, has its importance reduced and delegated to IT Departments. On the last two decades, a new IT risk management perspective raised, bringing an holistic view of IT risk to the organization. According to this new perspective, the strategies formulation process should take into account the IT risks. With the growing of IT dependence on most of organizations, the necessity of a better comprehension about the subject becomes more clear. This work shows a study in three public organizations of the Pernambuco State that investigates how those organizations manage their IT risks. Structured interviews were made with IT managers, and later, analyzed and compared with conceptual categories found in the literature. The results shows that the IT risks culture and IT governance are weakly understood and implemented on those organizations, where there are not such an IT risk methodology formally defined, neither executed. In addition, most of practices suggested in the literature were found, even without an alignment with an IT risks management process

Estudo sobre a mortalidade e sobrevivência de micro e pequenas empresas natalenses e seus impactos nas políticas públicas pró-empreendedorismo

The principal purpose of this research was to investigate discriminant factors of survival and failure of micro and small businesses, and the impacts of these factors in the public politics for entrepreneurship in the State of Rio Grande do Norte. The data were ceded by SEBRAE/RN and the Commercial Committee of the Rio Grande do Norte State and it included the businesses that were registered in 2000, 2001 and 2002. According to the theoretical framework 3 groups of factors were defined Business Financial Structure, Entrepreneurial Preparation and Entrepreneurial Behavior , and the factors were studied in order to determine whether they are discriminant or not of the survival and business failure. A quantitative research was applied and advanced statistical techniques were used multivariate data analysis , beginning with the factorial analysis and after using the discriminant analysis. As a result, canonical discriminant functions were found and they partially explained the survival and business failure in terms of the factors and groups of factors. The analysis also permitted the evaluation of the public politics for entrepreneurship and it was verified, according to the view of the entrepreneurs, that these politics were weakly effective to avoid business failure. Some changes in the referred politics were suggested based on the most significant factors found.

Relações entre mecanismos de coordenação e controle com desempenho organizacional: um estudo nas instituições públicas de ensino médio de Natal

This research aimed at relating coordination and control forms to organizational performance. The multicase study was applied in two public high schools: Centro Federal de Educação Tecnológica do Rio Grande do Norte and Floriano Cavalcanti. In order to accomplish these objectives, it was developed a qualitative analysis and considered coordination and control forms of several authors. Also was considered Sander´s (1984) model of organizational performance. The mentioned model considers two criteria to analyze organizational performance: one instrumental (efficiency and efficacy) and other substantive (effectiveness e relevance). The research attempts to show the importance of balancing these criteria in a way that effectiveness and relevance becomes more important at schools. It was proven that the use of bureaucratic coordination forms has the power to influence the evaluation on the instrumental technique. At the same time, it was observed that the use of mechanisms based on the autonomy of the school is related to efficiency and efficacy. The object of this research can be considered successful
