Privacy has become an important aspect when modeling computational systems that have personal information and actions that deal with them. Control access models are used to provide security of such information. Some of these models, altough, are just applied to specific domains. It is proposed an access control model simple yet generic enough to comply with the security and privacy aspects of a system. The proposed model uses an adaptive automaton to perform the access control, and has a set of privacy commands, coded from a legislation or policy. These commands verify if a certain action in the systen may be characterized as a privacy violation. Moreover, the model may be used with auditing mechanisms to register actions in the system and guarantee the privacy.

Plastics materials produced from petrochemicals are widely used due to their versatility, mechanical properties and low cost, but they cause environmental impact as a consequence of the accumulation of great amount of these conventional synthetic polymers. The problems caused by the waste disposal of these petrochemicals plastics impel the development, production and application of biodegradable polymers, however these polymers have high costs and nonsuitable mechanical and physical properties. Therefore, a study of polymeric blends and systems made of poly(hydroxyburyrate-co-valerate) PHBV, poly(butylyneadiapate-therefhtalate) Ecoflex® and corn starch, waxy corn starch and manioc starch has been done. These polymeric blends and systems were evaluated using the Melt Flow Index (MFI), Differential Scanning Calorimetry (DSC), Thermogravimetry (TG), Heat Deflection Temperature (HDT), Mechanical Tensile and Impact tests, Scanning Electron Microscopy (SEM) and biodegradation test. The results obtained indicate transesterification reactions verified by DSC and TGA, lack of adhesion between corn starch and PHBV as indicate by mechanical tests and SEM, disagreement between the values obtained in this study and the values indicated by the manufacturer concern to the Ecoflex® and good biodegradation results. This study therefore indicates that it is possible to obtain materials viable for short-term applications, with adequate physical and mechanical properties and biodegradation.

The cyanobacterium Anabaena spiroides, a cosmopolitan species occurring in eutrophic environments as in Barra Bonita reservoir, is covered by a thick polysaccharide capsule that provides a microenvironment for association of bacterial communities. The aims of this study were: to identify bacteria attached to A. spiroides capsule to evaluate interspecific relationships among bacteria communities and A. spiroides, considering bacteria selectivity and succession dynamics of attached bacteria; as well as the effect of bacterial inoculum (1.2 µm filtered water from Barra Bonita reservoir) on cyanobacterial growth. For this purpose, density, production, biomass and diversity of bacteria attached to cyanobacteria capsules and free-living bacteria were determined in two replicate cultures of A. spiroides inoculated with bacteria from Barra Bonita reservoir. The diversity was verified by the number of bands obtained through separation of PCR amplification products of 16S rDNA from free-living and attached bacterial communities using Denaturing Gradient Gel Electrophoresis (DGGE). Bacteria attached to the capsule were identified by sequencing the fragment of 16S rDNA. A set of cultures were performed to evaluate cyanobacterial growth as affected by Barra Bonita filtered water. A. spiroides cultures without Barra Bonita inoculum were used as control. The results showed that bacterial density, biomass and total production were higher for free-living bacteria, but no significant difference was obtained between attached and free-living bacteria regarding production per cell. The diversity was lower for the attached bacteria than free-living ones. Three strains of attached bacteria present in A. spiroides inoculum, identified as one Acidobacteria and two Alphaproteobacteria, remained up to the beginning of exponential growth phase. At the senescence phase these bacteria were replaced by four strains identified as one Deltaproteobacteria, one Betaproteobacteria, one Bacilli (Firmicutes) and one unidentified strain. This research demonstrated that there were selectivity and succession in the bacterial community attached to A. spiroides, and that the addition of the filtered water from Barra Bonita inoculum accelerates the death of cyanobacterium cultures

The capability to use the language is essential for the acquisition of the symbolic systems and to improve the interpersonal relationships; his/her full development depends on the cognitive abilities and social adaptative skills. When an implication happens in this natural course, it is common to appear alterations in the communicative process. The speech pathologist s intervention in group, when using Augmentative and Alternative Communication as an intervention procedure, makes possible the complete use of the social interactions in the development of the language abilities. The objective of the present study was to plan, to apply and to evaluate an intervention program about Augmentative and Alternative Communication in a group inserted on a naturalistic model in one Special Education School. The ten students who participated in the research had a diagnosis of intellectual disabilities. Three of them were the target subjects. In order to be the target, they had to be non verbal. In the group of seven children there were some who were verbal and others nonverbal ones. All of the ten participants were capable to accomplish voluntary motor actions and they did not participate in other intervention group that used Augmentative and Alternative Communication. The chronological age of the group varied between 6 and 14 years old. To verify the effects of the intervention Program on Augmentative and Alternative Communication in the participants communicative behavior, a Multiple Baseline design across subjects was used. The sub-test Pragmatic from Test of Infantile Language ABFW and the Test of Receptive and Expressive Language were also used. The Results demonstrated that during the Baseline, none of the participants obtained success in relation to the use of the communication pictures. However, when the intervention process was started, the children presented increase in the use of pictures as an alternative to communicate their needs. At the end of the data collection all children were able to use the picture exchanging program. The Pre and Post results related to the Pragmatics Evaluation revealed that all the participants from each group improved their communicative abilities. It is important to emphasize that some of them improved their verbal behaviors and the ones who did not have conditions to improve their oral communication, started to use the pictures to communicate their needs associated with gestures and vocalizations. The application of Pre and Post Test on Receptive and Expressive Language Test, evidenced changes when the expressive language is analyzed. Some participants acquired abilities related to language verbal expression, even thought this was not the study main focus. We concluded that when the System of Augmentative and Alternative Communication was employed, the development of the communicative abilities occurred, improving the participants' communication performance during the interactions. Therefore, it is evident the importance of the speech pathologist s intervention in group situations and the use of the Communicative Alternative and Augmentative Systems to develop communication skills in children with intellectual disabilities.

The study on data integration is not new but neither is exhausted. Its need is increasingly clear due to the search for information in a general environment with increasing availability of data proceeding from distributed and heterogeneous sources. An approach used successfully, especially to solve the problems of heterogeneity of sources, is the use of ontology, as the basis for the data integration systems. In order to employ this concept, this work describes the development of a data integration system based on ontology, DISFOQuE, which has its use as a motivation in the field of watersheds analysis.

To prepare quality learning material that can provide meaningful learning, considering the students previous knowledge, the place where they live in and the culture they acquire along their lives, i.e. their common sense, is still a great challenge for learning process. Considering the context of e-learning, focusing on Distance Learning (DL), this challenge is even bigger, because teachers and students are separated physically and/or temporally. Teachers have to deal with using computer and Internet in order to edit Web content, guaranteeing support for students meaningful learning. Organizations dedicated to DL and universities have created the concept of Learning Objects (LO), a format for organizing and structuring any digital material focused on education. For teachers to use common sense knowledge in LO edition, two module supported by common sense knowledge was integrated into Cognitor, a computational framework to edit Web-like learning material. One of the modules gives access to the Open Mind Common Sense (OMCS-Br) knowledge base and, given a concept on which teachers wish to work on, other related concepts are retrieved from the common sense knowledge base and presented to teachers who can insert them into the structure of the hyper document in order to elaborate related contend for that concept afterwards. In the case studies developed in this project, a verification was performed on the common sense support for helping teachers to structure LO with better quality by using the Knowledge View assistant available in Cognitor, which is based on Novak s Conceptual Map Theory, applying the patterns of CogLearn, a HCI and Pedagogical Pattern Language developed at the Advanced Interaction Laboratory (LIA). Besides of that, the potential use of such kind of knowledge for fulfilling LO metadata, making easier their reuse, is approached in a second module available on Cognitor.

Computer simulation can be used to assess future risks and to support decision making and can be modeled either for quick runs to predict the state of a real-world system or for indeterminate runtime to allow human interaction in a virtual environment for training. To facilitate the modeling and implementation of those simulations, many commercial software suites are available, but proprietary technologies are limited when there is the need to reuse a particular implementation together with other solutions. Faced with the need for interoperability, the High Level Architecture (HLA) standard defines a communication infrastructure for data sharing and synchronization among distributed simulation models. Using the HLA as its basis, this work defines a framework to generate an application for simulation control and management using tridimensional graphics for visualization through the Extensible 3D (X3D) standard. The X3D specifies a runtime environment for 3D content presentation and defines a language and a set of components to describe that content. By using the HLA and X3D standards integrated into technologies such as Web services, this framework provides a solution to visualization and control of distributed simulations in different software and hardware platforms.

Due to the fact that governmental decisions centralize local sustainability as a basis for reaching global sustainability, planning and establishing directives for municipal territories are growingly important. Therefore, the objective of the present study was to characterize, analyze and elaborate a conceptual proposal for ecological-economical zoning in the city of Santa Cruz da Conceição, state of São Paulo, Brazil, using Geographical Information Systems GIS in order to create a digital georeferenced database that would enable the understanding of the structure and functioning of natural systems for the sustainable use of natural municipal resources. Characterization and zoning were based on topographical charts and aerial photographs. Results led to the construction of maps of structural elements in the landscape, analysis of erosion risks, and definition of zones of environmental fragility. For each zone, the problems, limitations and potentials were determined. Besides, tendency and directions were projected in order to determine general and specific directives for the preservation of natural characteristics and prioritization of the potentialities in each area. The municipal territory was divided into four zones that showed distinct levels of environmental fragility: zone of major relative environmental fragility (ZMAF), zone of medium relative environmental fragility (ZMEF), zone of major relative environmental stability (ZMAE) and urban zone (ZURB). ZMAF and ZMEF were predominant in the landscape of the city with 37.54% and 41.62% of the area, respectively. Results obtained evidenced the need to determine legal public, technical and financial tools for the social control of existing environmental impacts, to substitute and diversify socialeconomical matrices and to adequate the use of natural resources to local environmental fragilities.

High rubber content acrylonitrile-butadiene-styrene terpolymer (ABS) has been used to tough PBT. As a result, super tough PBT/ABS blends under notched Izod impact have been obtained. However, there has been a significant reduction in the PBT/ABS Young modulus. The development of an optimum stiffness-toughness balance in PBT/ABS blends can be achieved by addition of short glass fibers to the composite blends. The composite performance is strongly dependent on the matrix-fiber interface and consequently the surface treatment of the fiber is a key factor to be considered. In the present work, the effect of two kinds of glass fibers treatment on the mechanical properties of PBT/ABS blends is investigated and the results discussed in terms of the changes of the fiber wettability and interfacial adhesion strength of the fiber to the resin. The processing conditions used to prepare glass fiber reinforced tough PBT/ABS blends were studied to observe the best conditions to maintain the toughness and stiffness of the blend as high as possible. A twin screw extrusion was used to prepare the reinforced PBT/ABS blends. Tensile, impact and essential work of fracture (EWF) testing was carried out to evaluate the mechanical properties for stiffness and toughness of the reinforced blends, respectively. The results have shown a strong dependence of the mechanical properties on the surface treatment of the fibers and these results are corroborated by electron microscopy micrographs that clearly illustrate the changes in the composite fiber/matrix interface in the presence of differences in surface treatments of the fiber. The development of an optimum stiffness-toughness balance in PBT/ABS blends was achieved and EWF has been successfully applied to evaluate the toughness for PBT/ABS blends.

The aim of this work is to analyze the NUPES academic production, specifically 23 serial researches of Work Documents periodic from 1989 to 2005. The principal objective is to investigate if NUPES academic production was antecipated, in scientific means, to political process and educational laws development process since 90´s decade, keeping in mind Brazilian superior educational official changes. Our specific aim is to identify the concept of scientific publication autonomie of this section, and this concept evolution also. We tried to reflect how political aspirations, vizualazed and projected by NUPES for almost two decades are been incorporeted by educational law arcabouço and based on science and tecnologie Conselho Nacional de Desenvolvimento Científico e Tecnológico-CNPq, analized here by the editais from 2003-2004. The research point out evidences that NUPES proposal Project after 16 years turned them not only a protagonist but na important part of thematic, theorical and methodological field of superior educational reform process. Their researchs, publications, discussions abreviated politics that are incorporate to life by laws, decrees, and measures. The politics point out that the State is suffering a new political orientation, that had been done by NUPES from two decades in BRazil. These orientations focusing on public universities has been materializing under political forms stimulating the management switc, employes hire, its spend, and the new function that demands to the university. All the analysis bring us to a commun place, indicating a academic culture, professor-researcher profile (now a entrepreneur) and flexibility that this politics demands, are changing movements into the university, indicating less scientific autonomie power in academic university space. All this movement bring us to a new State politics, that uses public means to invest in politics direct from productiv section, providing a new knowedlege dimension, not meeting politic and academic time neither social comportament, breaching the three pilars of the university: scientific, financial and didactic autonomy.

The collection and maintenance of the material used in this paper were financed by the Biota/ FAPESP project (process 1998/05083-0). The main objective of this study is to come to know the Stiropius Cameron, 1911 (Hymenoptera: Braconidae: Rogadinae) fauna in 8 localities in the Atlantic Rain Forest distributed by the Southeastern part of Brazil, aiming to amplify the taxonomic knowledge of the group mentioned before. The genus includes 18 described species, only one from Brazil. Using Malaise and Moericke traps and sweeping of the vegetation 44 units of the genus Stiropius were collected and identified as 31 different species: 5 were already described by ACHTERBERG (1995) in Central America and 26 new species: 7 in Sao Paulo State, 12 in Rio de Janeiro State and 7 in Espirito Santo State. The richness of species is significant when compared to the number of samples that were found, suggesting that the genus Stiropius constitutes a diverse group in the Atlantic Rain Forest and indicates the shortage and viability of new studies with the genus Stiropius, approaching the Rain Forest biome and the south-American continent in general, since reviews of the genus before this paper were carried only for North and Central America.

The use of computer games for education is getting more and more common, since they are considered a potential tool for facilitating the learning process, making it more comfortable and natural for students. However, the majority of the existent educational games neither allows content personalization nor offers any support for teachers to contextualize the game content to the socio-cultural reality of a certain group of students. The environment What is it? developed in this project allows teachers to co-author card-based quiz games and offers common sense support from a common sense knowledge base previously filtered by teachers, according to the desired student profile, making possible fit the content for the students needs. The environment is divided into three modules: (I) the editor s module, where teachers can create a game instance; (II) learner s module which is used by players to guess the secret word of a game card (for instance, AIDS), which is related to a topic (STD Sexually Transmitted Disease, for example) that is referred to one of the transversal themes proposed by SEF/MEC (for example, Sexual Education), inferring the word from the clues that are presented one by one; and (III) the evaluation module for teachers to analyze the performance of each student in playing the game and to make their conclusions. The environment also proposes a new way for collecting common sense knowledge through which mechanisms on the editor s and player s modules store all the interaction of teachers and students with the system, mapping the data gotten from the interaction in relations stored in the Open Mind Common Sense (OMCS-Br) knowledge base, which currently collects common sense knowledge in the form of natural language statements through voluntary contributions in the site of the project (http://www.sensocomum.ufscar.br). For assessing the environment, a case study was performed in two state schools one in São Carlos/SP and another in Foz do Iguaçu/PR that allowed to certify the interest of teachers and students in using this kind of educational tool and to collect opinions from teachers about using common sense knowledge for contextualizing the generated content. Moreover the potential for collecting new common sense statements through the game, contributing towards making the OMCS-Br common sense knowledge base grow faster, is demonstrated.

The early years of professional activity are the period in which new graduates face the challenge of completing their transition from students to teachers. Research has shown that this phase is characterized by intense learning and significant stress, often in unfamiliar contexts where the beginners are required to attain professional skills while maintaining a certain level of personal balance (Marcelo, 1998). Many interfering factors will affect the daily routine of beginning teachers, frequently leading to a number of obstacles to overcome. This work applies a qualitative approach in the detection and resolution of such difficulties from a collaborative perspective, using workgroup cooperation as a central strategy. It also investigates the contribution of workgroup strategy to the development of beginning teachers, and to the beginners ability to face and overcome arising problems. Theoretical references were taken from previous studies on the recent trends in teacher development, the knowledge basis of teaching and the processes of pedagogic reasoning. Collaborative research was performed with a group of four beginning elementary school teachers who attended weekly meetings over a one-year period. The full-length transcripts of all meetings served as the main source of pertinent data, supplemented by several written accounts produced by the participants themselves. Results show that, among the several challenges encountered by teachers in their day-to-day activities, classroom management issues can be considered as the primary source of difficulties. The group was effective in proposing solutions to reported problems and in contributing to the professional development of beginners. Works of this nature, however, can be limited by a number of factors, such as the time span between the establishment of a group and the moment it becomes truly collaborative (Grossman et al, 2001). Despite that fact, the group used in this study rendered meaningful results and showed that the theorization of day-to-day classroom experiences can constitute a powerful instrument for the professional development of teachers.

A summary of the state of the art relative to regression models for binary response variable and panel data is presented in this work. Those models may include efects from several sources: specific variables of interest, heterogeneity between individuals and lagged values of the response variable. The original contributions of the author are simulation studies to compare two diferent approaches to maximum likelihood estimation of parameters of dynamic models with all three kinds of efects, and also a study of properties of such estimators in group sequential analysis, using the bootstrap methodology. Original codes were developed in R for implementation of simulation studies. The relevance of the subject and the non availability of appropriate codes in commercial software for fitting dynamic models for binary response justify the choice of the theme.

For the most part of modelings in the credit risk area, the most widely used model is the credit scoring, and as the main statistical technique, the binary logistic regression, used to determine whether a customer is a good or bad payer. In this academic work an alternative methodology is proposed, where the estimative is formed based on the scores obtained by customers; this means the response follows a binomial distribution. In this modeling the combined estimate of scores of various products used by customers is included, considering the correlation between these scores.

In medical and biological researches we often .nd count data. For longitudinal count data, usual Poisson regression models, assuming independence among observations, are not applicable because of the correlation of these measures. This work presents hierarchical Bayesian models considering random e¤ects to analyze longitudinal count data. A Normal and a Gamma distribution are considered to these e¤ects besides the mixture of Normal distributions. We also present zero in.ated Poisson (ZIP) regression models for repeated measures. Markov Chain Monte Carlo (MCMC) is used to estimate the parameters. Keywords: Longitudinal Count Data; Poisson Regression Model; Zero In.ated Model; Hierarchical Model; Bayesian Analysis; MCMC Methods.

This research searched to identify and to analyze the main factors that influence the expression and development of the ethics in an organization of the state public sector Secretaria da Fazenda do Estado de São Paulo - SEFAZ, addressing the space occupied by Agentes Fiscais de Rendas - AFRs. The concern with the issue of ethical values is increasingly present in the public sector. Several fronts seems to announce the return of ethical philosophy: the development of new schools of thought, the renaissance of the ethical debate and the multiplication of the discussions. The structuring of the work stems from the history and unique position of the author, Production Engineer and AFR in the organization studied. Based on the multidisciplinary profile that characterizes Production Engineering, we sought to undertake an exchange to enable a fruitful discussion between the two fields. The first part of the work consisted of pointing out the problem of research against a broader background and theoretical reference chosen for it. Then the studied organization was presented and described their history together with the morphology of its population, composed of inspectors and other categories of servers. We show how the concepts relevant in this field: inspectors, taxes,internal mechanisms of control, ethics are constructed objects, resulting in a continuous process of evolution of the organization. The instruments for the control of conduct relating to the inspectors were identified and presented following a time sequence trying to define the rationale, motivation and support that had created the conditions for the formation of the instruments of the organization. We note that the process of building mechanisms of control surpasses the limits of the organization, coming to receive the influence of players as far away as: national and international civil organizations, media, academia, business and other public agencies. There is a dynamic process of export-import of theoretical models in the process of deploying the mechanisms of control. The rationality that these models praise, as the increase of emphasis in efficiency or visibility of the organization, dispute space with the civic ideal underlying the relationship between the public service and citizens. The existence of multiple rationalities in the mechanisms of control can be a factor of uncertainty in the form of public officials to give accounts. On the other hand, it also indicates that the public service and its servers are not indifferent to the yearnings of the society in the fight against the corruption, meeting agents worried in interpreting and taking care of the yearnings of ethics emanated by the society.

The new product development (NPD) is essential for the competitiveness, mainly for small and medium sized Technology-based Companies (TBCs), which innovation can be considered one of its main business process. The objective of this thesis is characterizing and proposing a reference model to the NPD in small and medium sized TBCs from the process control automation (PCA) and medical-hospital equipment (HME) sectors. The specifications to develop the reference model were done according to a practical research, which considered both quantitative and qualitative research method. Firstly, a survey was done based on a sample of 62 TBCs in order to characterize practices used in the NPD management. Elucidation of the results generated from the statistical procedures enabled to find a set of factors (practices) that affect the success of product development in these companies. Management factors related to the pre-development activities, the role played by the leader in the NPD project and the proficiency in executing the activities of technical development were indicated as a determinant factor of success. After this process, a qualitative research was done in four TBCs in order to analyse better the PDP of these companies. After the empirical evidence in the analysis and considering the theoretical reference about the NPD, it was possible to formalize a number of proposals which enabled a reference model to manage the NPD in small and medium sized TBC from PCA and HME sectors. The model has five dimensions: strategic orientation; process; organization and leadership, evaluation and performance and resources. The research enabled to characterize the NPD management in such a specific companies and to provide a reference model, which can be used as a diagnostic and support to the organization of the NPD management in small and medium sized TBCs.

This paper is all about spatial perception in order to be used at participative process of urban planning. The spatial perception to deal with the relationship between human being and space to identify needs, desires, opinions, appropriation level, to have a basic grasp of citizen and so on. The urban process has taken the human being to adapt to transformed space, instead of to adapt to space to human being, to take for granted the consequences of life quality.
