O governo federal tem realizado esforços e iniciativas a fim de modernizar e melhorar a eficiência da máquina publica. Dentre essas iniciativas está o incentivo do uso de sistemas de informação por meio do programa de governo eletrônico e o mais recente esforço o decreto nº 8.539, que dispõe sobre o uso do meio eletrônico para a realização do processo administrativo no âmbito dos órgãos e das entidades da administração pública federal. Neste sentido de modernização e melhoria foi desenvolvido um sistema de informação que permite controlar todo o processo de afastamento de servidores da Universidade Federal de Minas Gerais (UFMG). Porém de nada adianta investir em sistemas de informação sem o mesmo seja efetivamente utilizado e aceito pelos seus usuários. Este trabalho tem como objetivo analisar o uso do sistema de informação para controle de afastamentos da UFMG, por meio da integração dos modelos TAM e TTF, sob a percepção dos usuários que utilizam o sistema como parte de seu processo de trabalho. A pesquisa é classificada como quantitativa, descritiva e exploratória tendo como método de pesquisa o tipo survey e como população os funcionários dos setores que participam diretamente do processo de afastamento.

Estudos científicos têm demonstrado a existência de diversos fatores de influência sobre o processo de adoção de Tecnologia da Informação. Vários aspectos potencializadores das intenções de uso das tecnologias parecem estar presentes nas decisões sobre a adoção de tecnologia como, por exemplo, vantagens relativas obtidas pelo uso da tecnologia, conhecimento requerido para operação dos sistemas, facilidade e utilidade uso da tecnologia, entre outros. No entanto, há estudos que demonstram que o processo de adoção de tecnologia pode não ser explicado, somente, por aspectos financeiros e mercadológicos, mas englobar fatores endógenos que interferem nas decisões dos usuários sobre o uso de tecnologias de informação. Teorias e modelos de adoção de tecnologias conseguem explicar uma parcela dos motivos que levam os indivíduos a se comportarem de acordo com o uso de uma determinada tecnologia. Por exemplo: hábito individual, conectividade e conveniência podem influenciar as preferências de uso de uma determinada tecnologia de informação. De acordo com estas teorias, é possível analisar as influências que os indivíduos percebem e consideram nas decisões como justificativas sobre o uso de tecnologias de comunicação pessoal, além da busca exclusiva por resultados econômicos. Observa-se que um dos segmentos de tecnologia que apresenta condições de diferentes ofertas e múltiplas funcionalidades se refere ao segmento de tecnologias de comunicação de voz no qual o usuário pode se comunicar por meio de linhas telefônicas fixas, móveis, Internet, entre outras formas. Para a operacionalização de uma análise de adoção de tecnologia que englobe múltiplas interações de influências ao usuário, optou-se pela contextualização do estudo com foco na tecnologia de comunicação de voz pela Internet – VOIP, pois quando comparada com outras tecnologias de comunicação, adiciona-se que a gratuidade de ligações entre usuários de um mesmo sistema pode ser apresentada como um dos benefícios econômicos principais, aliada a outros benefícios provindos da telefonia em si. Os resultados obtidos por esta pesquisa confirmam a influência de diversos fatores posicionados em diferentes dimensões e proporcionam conclusões relevantes à adoção das tecnologias de comunicação de voz sobre Internet. Conclui-se que as percepções individuais sobre as características da tecnologia, a rede de contatos do usuário, hábito de uso e incentivos comerciais destinados ao uso de outras tecnologias de comunicação podem formar uma rede de influências à adoção da telefonia VOIP frente às percepções sobre os benefícios que podem ser obtidos com o uso desta aplicação.

O Programa de Triagem Neonatal de Minas Gerais (PTN-MG), cuja rede estadual é composta por mais de três mil Unidades Básica de Saúde (UBS), é uma estratégia de diagnóstico precoce do Sistema Único de Saúde (SUS) de extrema importância para a população. Para alinhar o sistema de informação do Programa à essa premissa, este estudo apresenta o seguinte problema: Quais são os fatores determinantes do uso de um sistema de informação do PTN-MG e quais são as relações entre eles? Buscou-se a partir de um estudo no âmbito do SUS em Minas Gerais, com a aplicação de um survey a todas as Unidades Básicas de Saúde do Estado que utilizam o sistema de informação, desenvolver um módulo de sistemas de informação inteligente para toda rede Estadual; avaliar as percepções dos usuários baseando-se na integração dos modelos TAM e TTF (KLOPPING; MCKINNEY, 2004) com variáveis de Índice de Desenvolvimento Humano dos municípios e a capacidade de coleta das UBS; analisar os fatores determinantes do uso do SI e suas respectivas relações. O modelo continha 16 hipóteses, sendo que 06 foram confirmadas a partir de um estudo realizado por modelagem de equações estruturais. Os principais resultados indicaram que a maioria dos usuários concordou que o sistema de informação é útil, fácil de usar e ajustável às suas tarefas. O estudo confirma também que os modelos TAM e TTF se completam, pois apresentam várias relações significativas entre os seus constructos. Outro achado importante, foi a relação inversa encontrada entre o IDHM do município e a percepção de utilidade do modelo TAM. Entende-se que o estudo cumpriu com o objetivo proposto e ainda gera novas expectativas futuras como: aplicação do modelo em outras realidades e a inclusão de outros constructos sociais para verificação de possíveis relações com o modelo TAM/TTF.

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

In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ²) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public.

En la investigación en e-Learning existe un interés especial en la adaptación de los objetos de aprendizaje al estudiante, que se puede realizar por distintos caminos: considerando el perfil del estudiante, los estilos de aprendizaje, estableciendo rutas de aprendizaje, a través de la tutoría individualizada o utilizando sistemas de recomendación. Aunque se han realizado avances en estas facetas de la adaptación, los enfoques existentes aportan soluciones para un entorno específico, sin que exista una orientación que resuelva la adaptación con una perspectiva más genérica, en el contexto de los objetos de aprendizaje y de la enseñanza. Esta tesis, con la propuesta de una “red multinivel de conocimiento certificado” aborda la adaptación a los perfiles de los estudiantes, asume la reutilización de los objetos de aprendizaje e introduce la certificación de los contenidos, sentando las bases de lo que podría ser una solución global al aprendizaje. La propuesta se basa en reestructurar los contenidos en forma de red, en establecer distintos niveles de detalle para los contenidos de cada nodo de la red, para facilitar la adaptación a los conocimientos previos del estudiante, y en certificar los contenidos con expertos. La “red multinivel” se implementa en una asignatura universitaria de grado, integrándola en los apuntes, y se aplica a la enseñanza. La validación de la propuesta se realiza desde cuatro perspectivas: en las dos primeras, se realiza un análisis estadístico para calcular la tasa de aceptación y se aplica un modelo TAM, extrayendo los datos para realizar el análisis de una encuesta que cumplimentan los alumnos; en las otras dos, se analizan las calificaciones académicas y las encuestas de opinión sobre la docencia. Se obtiene una tasa de aceptación del 81% y se confirman el 90% de las hipótesis del modelo TAM, se mejoran las calificaciones en un 21% y las encuestas de opinión en un 9%, lo que valida la propuesta y su aplicación a la enseñanza. ABSTRACT E-Learning research holds a special interest in the adaptation of learning objects to the student, which can be performed in different ways: taking into account the student profile or learning styles, by establishing learning paths, through individualized tutoring or using recommender systems. Although progress has been made in these types of adaptation, existing approaches provide solutions for a specific environment without an approach that addresses the adaptation from a more general perspective, that is, in the context of learning objects and teaching. This thesis, with the proposal of a “certified knowledge multilevel network”, focuses on adapting to the student profile, it is based on the reuse of learning objects and introduces the certification of the contents, laying the foundations for what could be a global solution to learning. The proposal is based on restructuring the contents on a network setting different levels of depth in the contents of each node of the network to facilitate adaptation to the student’s background, and certify the contents with experts. The multilevel network is implemented in a university degree course, integrating it into the notes, and applied to teaching. The validation of the proposal is made from four perspectives: the first two, a statistical analysis is performed to calculate the rate of acceptance and the TAM model is applied, extracting data for analysis of a questionnaire-based survey completed by the students; the other two, academic qualifications and surveys about teaching are analyzed. The acceptance rate is 81%, 90% of TAM model assumptions are confirmed, academic qualifications are improved 21% and opinion survey 9%, which validates the proposal and its application to teaching.

Esta pesquisa faz parte dos requisitos do Mestrado Profissional em Sistemas de Informação e Gestão do Conhecimento e tem como tema central aceitação de tecnologia e prontuário eletrônico de paciente (PEP). Diversas inovações tecnológicas foram incorporadas no setor de saúde e, em especial, no controle e gestão de informações e ainda quanto à gestão do histórico do paciente. A partir deste cenário, buscou-se contribuir na descrição e análise das variáveis percebidas como geradoras de utilidade e facilidade de uso da tecnologia de prontuário eletrônico a partir do modelo de aceitação de tecnologia. Buscando atender as premissas propostas pelo modelo TAM, no contexto específico de gestão hospitalar, surge o problema de pesquisa: Como usuários de prontuário eletrônico de paciente percebem a utilidade e facilidade desta tecnologia em seu cotidiano? Pretendeu-se desenvolver estudo descritivo onde o objetivo principal foi descrever e analisar as variáveis que influenciam na percepção da utilidade e facilidade de uso de prontuário eletrônico de pacientes sob o ponto de vista dos profissionais da área da saúde da região Metropolitana de Belo Horizonte. Especificamente, pretendeu-se: descrever a percepção de utilidade; descrever a percepção de facilidade de uso, e; analisar o perfil dos respondentes envolvidos com a tecnologia. Optou-se por utilizar o questionário original proposto por Davis Jr. (1989), somente sendo traduzido e contextualizado ao ambiente da pesquisa. O questionário adotado foi disponibilizado por meio da ferramenta Survey Monkey ® e os respondentes foram profissionais que atuam na área da saúde, sendo o critério de escolha dos mesmos, por meio da técnica de snow ball, a acessibilidade e disponibilidade. A partir das respostas dos profissionais pode-se perceber que a grande maioria relatou utilidade percebida com o uso da tecnologia, sendo que alguns profissionais indicaram que ocorre ainda algumas dificuldades de uso. Os resultados e discussões gerados nesta pesquisa, apesar das limitações, indicam a importância de novos estudos que envolvam a saúde e a importância da tecnologia para a sociedade.

El Consejo Superior de la Judicatura ha adelantado programas de modernización tecnológica, tanto de los despachos judiciales como de los entes de administración de la rama judicial, pero aún se puede constatar la generalización del atraso judicial y consecuentemente, la pérdida de credibilidad en el sistema. Objetivo: Determinar el impacto que tiene el uso de las tecnologías de información y las comunicaciones en la gestión judicial de la Dirección Seccional de Administración Judicial de Cúcuta. Métodos: Se utilizó un tipo de estudio descriptivo, aplicado a 25 jueces, 115 empleados de los diferentes despachos judiciales y a 5 magistrados quienes fueron actores clave para el estudio. Resultados: Los resultados indican que el impacto de las TIC en la gestión judicial de la Entidad es moderado basado en las limitaciones actuales del flujo de información con los usuarios y con las demás entidades de la rama judicial. Conclusión: No se ha integrado el sistema de información con todos los municipios de la región de Norte de Santander y Arauca. Adicionalmente, a pesar que se cuenta con herramientas tecnológicas para mantener interactividad con proveedores y usuarios del servicio judicial, el personal de la Entidad no los conoce completamente por la resistencia al cambio que supone realizar las tareas de diferente manera.
