NURSES AND THE ASSESSMENT IN HEALTH SYSTEM MANAGEMENT

The objective of this study was to undertake a critical reflection regarding assessment as a managerial tool that promotes the inclusion of nurses in the health system management process. Nurses, because of their education and training, which encompasses knowledge in both the clinical and managerial fields and is centered on care, have the potential to assume a differentiated attitude in management, making decisions and proposing health policies. Nevertheless, it is necessary to first create and consolidate an expressive inclusion in decisive levels of management. Assessment is a component of management, the results of which may contribute to making decisions that are more objective and allow for improving healthcare interventions and reorganizing health practice within a political, economic, social and professional context; it is also an area for the application of knowledge that has the potential to change the current panorama of including nurses in management.

Optimization of Large-Scale Hydrothermal System Operation

This paper presents the development of a mathematical model to optimize the management and operation of the Brazilian hydrothermal system. The system consists of a large set of individual hydropower plants and a set of aggregated thermal plants. The energy generated in the system is interconnected by a transmission network so it can be transmitted to centers of consumption throughout the country. The optimization model offered is capable of handling different types of constraints, such as interbasin water transfers, water supply for various purposes, and environmental requirements. Its overall objective is to produce energy to meet the country's demand at a minimum cost. Called HIDROTERM, the model integrates a database with basic hydrological and technical information to run the optimization model, and provides an interface to manage the input and output data. The optimization model uses the General Algebraic Modeling System (GAMS) package and can invoke different linear as well as nonlinear programming solvers. The optimization model was applied to the Brazilian hydrothermal system, one of the largest in the world. The system is divided into four subsystems with 127 active hydropower plants. Preliminary results under different scenarios of inflow, demand, and installed capacity demonstrate the efficiency and utility of the model. From this and other case studies in Brazil, the results indicate that the methodology developed is suitable to different applications, such as planning operation, capacity expansion, and operational rule studies, and trade-off analysis among multiple water users.

The 3C cooperation model applied to the classical requirement analysis

Aspects related to the users' cooperative work are not considered in the traditional approach of software engineering, since the user is viewed independently of his/her workplace environment or group, with the individual model generalized to the study of collective behavior of all users. This work proposes a process for software requirements to address issues involving cooperative work in information systems that provide distributed coordination in the users' actions and the communication among them occurs indirectly through the data entered while using the software. To achieve this goal, this research uses ergonomics, the 3C cooperation model, awareness and software engineering concepts. Action-research is used as a research methodology applied in three cycles during the development of a corporate workflow system in a technological research company. This article discusses the third cycle, which corresponds to the process that deals with the refinement of the cooperative work requirements with the software in actual use in the workplace, where the inclusion of a computer system changes the users' workplace, from the face to face interaction to the interaction mediated by the software. The results showed that the highest degree of users' awareness about their activities and other system users contribute to a decrease in their errors and in the inappropriate use of the system.

Facial symmetry evaluation after experimentally displaced condylar process fracture in methotrexate treated rats

PURPOSE: To investigate the facial symmetry of high and low dose methotrexate (MTX) treated rats submitted to experimentally displaced mandibular condyle fracture through the recording of cephalometric measurements. METHODS: One hundred male Wistar rats underwent surgery using an experimental model of right condylar fracture. Animals were divided into four groups: A - saline solution (1mL/week); B - dexamethasone (DEX) (0,15mg/Kg); C - MTX low dose (3 mg/Kg/week); D - MTX high dose (30 mg/Kg). Animals were sacrificed at 1, 7, 15, 30 and 90 days postoperatively (n=5). Body weight was recorded. Specimens were submitted to axial radiographic incidence, and cephalometric mensurations were made using a computer system. Linear measurements of skull and mandible, as well as angular measurements of mandibular deviation were taken. Data were subjected to statistical analyses among the groups, periods of sacrifice and between the sides in each group (alpha=0.05). RESULTS: Animals regained body weight over time, except in group D. There was reduction in the mandibular length and also changes in the maxilla as well as progressive deviation in the mandible in relation to the skull basis in group D. CONCLUSION: Treatment with high dose methotrexate had deleterious effect on facial symmetry of rats submitted to experimentally displaced condylar process fracture.

A Systematic Mapping on the Role-Permission Relationship in Role Based Access Control Models

Access control is a key component of security in any computer system. In the last two decades, the research on Role Basead Access Control Models was intense. One of the most important components of a Role Based Model is the Role-Permission Relationship. In this paper, the technique of systematic mapping is used to identify, extract and analyze many approaches applied to establish the Role-Permission Relationship. The main goal of this mapping is pointing directions of significant research in the area of Role Based Access Control Models.

Plano de inovação para o Vocabulário Controlado do SIBIUSP: relato de experiência

Controlled vocabularies are tools of representation of information necessary to standardize the content description and classification of information, making information systems consistent and also minimizing the dispersion of information. One of the most critical points of controlled vocabularies is the need to constantly update, in terminology and the computer system. The purpose of this paper is to share the experience of the Sistema Integrado de Bibliotecas da Universidade de São Paulo - (SIBiUSP) in planning and developing an innovation plan for your Controlled Vocabulary, reporting their goals and actions. Such actions are in different stages of referral, so there are provisional results. The article also brings the description of his movements and the difficulties encountered as collaboration and knowledge for professionals that working and researching with the theme controlled vocabularies

O enfermeiro e a avaliação na gestão de Sistemas de Saúde

Este artigo teve como objetivo refletir criticamente acerca da avaliação, enquanto ferramenta gerencial que favorece a inserção do enfermeiro no processo de gestão de sistemas de saúde. Em decorrência de sua formação, que engloba conhecimentos da área assistencial e gerencial, tendo como centralidade o cuidado, o enfermeiro tem potencial para assumir postura diferenciada na gestão e condições de tomar posições decisórias e de proposição de políticas de saúde. Entretanto, ainda há que se construir e consolidar inserção expressiva em níveis decisórios nos espaços de gestão. A avaliação é um componente da gestão, cujos resultados podem contribuir para tomada de decisão mais objetiva que possibilite a melhoria das intervenções de saúde e a reorganização das práticas de saúde, dentro de um contexto político, econômico, social e profissional; é também uma área de aplicação de conhecimentos que tem potência para mudar o panorama atual da inserção do enfermeiro na gestão.
