The action of the Human Being about the environment has promoted alterations in the natural characteristics which resulted in the resources degradation and a problem related to the quality of the present and future life in the city. The pressure of the growth of urban population and the difficulty of the city to supply, in the same velocity, the substructure demand, have created a disqualification of some urban spaces, and even an implication to the natural environment. On the other hand, in the last decades has appeared the sustentability concept that brings a perspective of a human action more responsible, concerning to the natural environment and to the future generations. Under these points, the propose is to analyse the tendency of the ecological sustentability in urbanistic undertakings projects of São Carlos City / SP, with the objective in helping with the definition and the development of Public Municipal Politics, mainly in small and medium ones. The analysis has been done since the collected data in iconographic material like maps and photos, visits in loco and investigation in some Public Organizations Processes. Besides, historical, cultural and spatial approaches have been done. In order to analyze the sustentability of the select undertakings, specific variables related to environmental aspects were adopted. In this way, a lot of causes of disadvantageous tendencies were detected and it results from the lack or inappropriation of the projects of different parts of the undertakings, and even more, the incorrect use of them, and besides that, because of the necessity of incorporation of sustentability principles in the society action. In this investigation were possible to compare the undertakings, to evaluate the grade and difficulty of use, the behaviour of the used subcomponents, and do some suggestions.

Considering the highest increasing of the elderly population in our country and simultaneously the increasing of morbidity rate of chronic-degenerative disease, in general, there are people seeking to be in attendance, at day centre or hospital; these people are dependents on and when come back home, need familial caregivers. The caregivers are the fundamental importance to keep the patient in his community, to prevent and treat the problems caused by the stress factors among them must contribute to reduce or to postpone the hospitalization of caregivers. Besides, the improvement on quality of life could give the caregivers do better help to patients by influencing positively on the chronic disease course. So, this research try to undestand the reality of the caregivers lifes who s relatives are chronic illnesses pacientes. With this knowlege, implement and evaluate the effectiveness of an intervention proposal with caregivers. The objective of this intervention is to attenuate the happened stress conditions of the care activities. The research will use interview with caregivers at USE, at Federal University at S.Carlos; this interview will be taped and latter, a transcription to analyze the content of answers and to elaborate the intervention plan, in that case, a course. The course will consist of informative aspect about disease and daily life activities, as well as, formative aspect about self knowledge. A quality of life instrument named Caregiver Burden Scale will be given to caregivers. After the intervention (course) the Scale will be give once more to verify the date and to check the efficacy of intervention.

Privatization policy spread out worldwide in the last decades on the 20th century. The process that was initiated in the 1970s during the Thatcher Government in Britain grew rapidly. In Brazil, between 1991 and 2000, over 130 public companies were sold to the private sector resulting in US$ 87,2 billion revenue. This dissertation intends to discuss and evaluate in a quantitative way how phenomena which were considered exogenous to the ownership exchange influenced the financial performance of the privatized companies at the manufacturing phase of the Brazilian Privatization Program. One of the most frequent arguments in favor of private ownership is the increase in profits. In Brazil, most companies sold at the manufacturing phase of the Brazilian Privatization Program experienced expressive improvement in their financial performance in the 1990s. Several authors attribute the positive results that privatized companies achieved to the increase in their internal efficiency associated with new management pattern. This work shows that apart from these elements, other events exogenous to the exchange in the ownership highly contributed to improvement on their economical performance. This work focus on the main companies privatized at the manufacturing phase. This selection is important and necessary. It is important because it refers to companies that play relevant roles in the national industrial complex in terms of production, as well as in revenue and assets. On the other hand, this selection is necessary because it assures a homogenous sample. All of them present the same manufacturing characteristics and faced a rather fast exchange ownership process under similar institutional apparatus. The results indicate that around 73% of the profits increas were due to exogenous factors for the analyzed companies. The steel industry was the sector that relied on the largest share in this type of events, scoring 80% of participation on the total variation of the operational cashflow between 1990 and 1994, followed by oil sector for which exogenous factors represent almost 36% of the explained total of variation in operational cashflow between 1991 and 1995. The aeronautic material sector presented values around 16% of share in exogenous events in the results between 1993 and 1998.

Kant with Sade represents an important moment of Lacan s theoretical trajectory and the way he understood the relevance of psychoanalysis as a discipline of modernity. According to Lacan, Freud promoted the foundation of a pioneer way to the problem of subjectivity, which, as it included the concept of unconscious, revolutionized all the approaches to ethics until that moment. It would not be possible, after Freud, to understand ethics without the imaginary dimension of fantasy. On the other hand, Kant with Sade is revealed as the symptom of an important impasse at Lacan s theoretical trajectory, especially concerning the relations among law, jouissance, and desire. This work intends to indicate the antecedents of the problem of ethics in Lacan s work that culminates in the production of the article in 1962.

To choose the right projects, to develop them fast, achieving high quality patterns, and respecting the costs pressures. These are no questionable demands in the actual market conditions. The utilization of Product Development Processes and Portfolio Management are some of the main manners to achieve these goals. The Product Development Process adopted in a specific organization should be essentially aligned with the product-life-cycle. In addition, companies need to evaluate and make decisions on the products / projects based in an overall view provided by the Portfolio Management systematics and tools. This research focuses in these issues. The main objective is to analyze the integration between the Product Development Process and the Portfolio Management in a company from the automotive industry aimed at identifying the best practices and improving opportunities. The research methodology is the realization of a literature review followed by a case-study. The main result is the proposal of a Portfolio decision model, and the realization of a case-study based on this model proposal. The main contribution is to detail the Portfolio decisions, based in a PDP model, along the product-life-cycle.

This work presents a layer for the manipulation of media based on the multimedia content description interface, MPEG-7. This layer realizes some parts of the MPEG-7 MDS (Multimedia Description Schemes), and being built by components, makes a base for the implementation of any application that has media manipulation requisites that range from the simplest ones to a database multimedia system. In this last case, it can be a system that have many operations being executed in a database, like multimedia data mining and indexing by low level features, all supported by MPEG-7. This layer was built to unify the necessities on manipulating media of many applications, integrating them and acting as a mediator. It provides interfaces so that the insertion of media together with their semantic annotation is possible, along with queries based on these semantic metadata derived from these annotations. A simplified model for the semantic annotation and queries for the ease of use of these interfaces was proposed, being the annotations and queries made in a similar manner. Finally, this layer allows the exporting of the query metadata on the format used by MPEG-7 for interchange between systems.

The present work approaches the subject of the social responsibility of businesses, considering the implications that the institutional environment exerts on business practices. The business world has increasingly emitted signals acknowledging its social duties, and with regards to Brazil, this has mainly occurred during the last decade of twentieth century. During this period, while taking the shoe industry of Franca as an object of study, the factories social responsibility is manifested in the creation of the Pro-Child Institute as a reaction taken by the local entrepreneurs against allegations of the use of child labor in the productive chain. The transformations verified in the national institutional environment are analyzed in the space of the four classic dimensions of the business social responsibility (economic, legal, ethical and philanthropic), aiming to understand the determining institutions for the phenomenon studied from the point of view of the actors. The perception of the footwear manufacturers associated with the Pro-Child Institute is obtained by means of interviews and survey of the historical declarations registered by the media. The content analysis is made by use of a matrix of thematic categories compatible with the treatment given to the subject of business social responsibility according to the influence of the institutions. The results reveal the preponderant force of economic interests associated with the international market, and the national fragility in the application of the legal measures, in the field of external social obligations, as well as the moral complacency of the actors involved and the restricted contribution of the governing structures toward philanthropic action to transform the local values relative to the use of child labor. The legitimacy of the businesses intermix with the economic interests in the reduction in the costs of transactions and its social representation, as to the relative weight of the institutions that conform to the environment.

During the last few years is possible to observ an significant increase of real time applications, , mainly of multimedia applications (e.g. video and voice streamming). Factors such as the popularization of broadband (e.g. XDSL) and wireless (e.g. 802.11 familiy and 802.15 pattern) networks, associated to the appearance of better devices and the increase of user s communications need, have contributed. Currently, with the appearance of new concepts of communications like home networks, it is possible to predict that real time applications will be part of user s daily. Anticipating a solution to that predict, this work proposes a proxy architecture with priorities of services for real time remote procedure calls, that uses the earlier amount of tra_c to predict the future occupation network, and choose the most appropriate policy to adapt the proxy to the environment future states.

Wireless sensor networks are increasingly being deployed for fine-grain monitoring of physical environments subjected to critical conditions such as fire, leaking of toxic gases and explosions. A great challenge to these networks is to provide channels that satisfy the necessities of the applications for events propagation, even in the presence of emergency conditions that can lead to node failures and path disruption to the sink that receives those events. Quality of Service (QoS) mechanisms can be applied that meet application requirements such as: low latency and packet delivery reliability, fast path repair in the presence of faults and network longevity with uniform energy dissipation. This work presents QoS-based routing solutions, which aims to meet, simultaneously, the main requirements mentioned above. The proposed solutions were implemented and simulated in the NS-2 simulator. Important metrics, such as end-to-end delay, packet loss rate, control messages overhead and energy consumption, were evaluated. The results show that the proposed solutions can be a potential alternative to the supervision and control of physical environments subject to emergency situations

Building actions related to health and safety in small and medium enterprises are not easy tasks, since these enterprises need to deal with poor information, lack of available resources and methodologies developed according to big company characteristics. Based on Case Studies techniques, the present study investigated in four SME not only the way health and safety interventions are carried on, but the reasons why they are conducted that way as well. This investigation made us conclude that lack of available resources, poor information access, the firm culture and management model exert clear influence on the way Heath and Safety actions are conducted. Ergonomics, if conducted in the small firm, will be guided by perception and based on informality, either for changes or measures of the changes. We can conclude that some rules and laws, as well as ergonomic tools, should be developed according to the limitations and needs of the small and medium firms, and so be used to help improve health and safety into them.

Different forms of iron had been determined in the blood of animals with resistance and sensitivity to bovine s ticks. The determined variables were: Iron in total, plasma and serum blood, quantified by flame atomic absorption spectrometry (FAAS); Fe (II), and Fe (III), quantified by spectrophotometry by flow injection analyses; iron freedom through flow dialysis and quantification by g raphite furnace atomic absorption spectrometry (GFAAS); and hematocrit (packed cell volume). The used techniques and the developed methodologies are shown as complementary and adequate for the inquiry of the forms of iron founded in the blood. Blood digestion was not necessary for FAAS total iron determination, avoiding possible contaminations and decreasing the time spending to sample preparation. The Fe(II) and Fe(III) flow injection speciation presented good reproducibility and easy to implement in routine analysis. After freedom iron separation by dialysis membrane, GFAAS allowed the determination of small iron amounts. A statistical study was used for better comparison among the evaluated variables. The t test indicated differences between Canchim and Angus animals resistant and sensible to ticks related to iron amount in the blood s plasma, and in the Fe(III) amount between Angus resistant and sensible animals. In spite of no conclusives, the results indicated a possible tendency related to bovine ticks resistance and iron blood form. With the use of the methodologies defined in the present work, studies with a grater number of animals and small variables could be applied to confirm this hypothesis.

As availability of data from several areas of knowledge grows, it is even more necessary to develop effective techniques to retrieve the desired information, aiming to reduce irrelevant answers and ensure that relevant results are not ignored. Considering this context, we present the FOQuE system, developed to perform query expansion in order to retrieve semantically relevant and broad results. Based on fuzzy ontologies, this system is able to obtain approximate results that satisfy user requirements according to expansion parameters defined by the user. The additional answers retrieved by the FOQuE system are classified according to the semantic expansion performed and the relevance to the query, therefore it is possible to improve results that are presented to the user.

This research aimed to develop a set of sustainability indicators for water resources management (CISGRH) in the Tiete-Jacare Basin Committee ambit. The CISGRH development occurred by three main steps. The first step consisted on conceptual base structuring and empiric object characterization, and this phase had as main product a group of specific sustainability principles applied to water resources management. There were also studied National and International experiences for indicators proposition and use, which subsidized, on second phase, proposition a list of potential indicators. Three consultation processes were accomplished, seeking to identify principal problems related to water resources to a specific area and possible indicators to monitor them. The involved agents direct or indirectly with water resources management and the specific region, such as committee members, academic and technical specialists, were consulted. The results obtained by undertaken consultations based the third phase that consisted on the CISGRH structuring. The obtained indicators could previously be correlated with most of specific sustainability indicators principles identified. It was still looked for to characterize each one indicator, under aspects as: obtaining process or calculation, possible data sources, climbs determination, frequency and wanted tendency. From the CISGRH elaboration process could be observed that different actors' participation to indicators and aspects or problems selection, to be monitored, is very valuable, bringing benefits as to insert them in the context and larger their involvement. Although the set of indicators have been submitted to different actors and analyses, it is recommended that these indicators are reviewed and updated continually, with intention to assist for new demands that can appear in CBH-TJ.

In this work, we study the Artin braid group, B(n), and the confguration spaces (ordered and unordered) of a path connected manifold of dimension ¸ 2. The fundamental group of confguration space (unordered) of IR2 is identifed with the Artin braid group. This identifcation is used to conclude that the confguration space of IR2 is an Eilenberg-MacLane space of type K(B(n), 1). Therefore, it can be proved that the braid group B(n) contains no nontrivial element of the finite order. We use this fact to prove a generalization of a 2−dimensional version of the Borsuk-Ulam theorem presented by Connett [3].

The basic result of a soccer game is the final scoreboard, which can be seen as a bivariate random vector. Theoretically and based on existent literature we can argue that the number of marked gols by a team in a game obeys a (univariate) Poisson distribution. Thus, the Bivariate Poisson distributions are studied, in special for the class "of Holgate" (1964). Using as information the recent results of the teams, whose confrontation we want to model, several methods were used for parameters estimation of the Bivariate Poisson class "of Holgate". The idea is to use procedures that supply the probabilities of occurrence of placares, so that thus the probability of the occurrence of a certain result (team home´s victory, draw or defeat) can be calculated properly. The parameters of Bivariate Poisson distribution "of Holgate" are assumed to have a dependence factors, such as attack, defense and field, that possibly explain the numbers of goals.

Addressees the systematization of logistical and commercial aspects of São Paulo s sugar exports through Santos Port facilities. Local political and economical liberal transformations that took place by the beginning of 90 s had seen Estate assets being given to private investments (both in agricultural and port operations). As a result, this new institutional environment allowed the occurrence of hybrids corporate structures to coordinate logistical sugar and alcohol-ethanol exports from inland facilities to the Santos port. The main question is how this adaptation interferes on infrastructural and operational logistics management derived from new transactions within international sugar mayor traders. The main units of analysis are: i) São Paulo s state sugar producers (industrial plants) and port logistics providers; ii) port logistics providers and food trading companies. Results shall foster the comprehension on logistical process and relations amongst the three main actors across the sugar plantsport facilities chain. There are three goals to be achieved: i) identify the total extent of logistical domain across sugar s distributional channels via port of Santos; ii) how logistical assets and processes are developed or provided within those actors; iii) describe the difference among Santos port operations service providers, in relation value-added competitive basis. Theoretical framework blends logistics and supply chain management with foreign trade prospects as a guideline to collect data and empirical evidences. This works object is the São Paulo sugar plants-port of Santos facilities logistics chain.

Nowadays, the microorganisms are responsible for the production of several antibiotics, immunosuppressant and antitumors, furthermore they are extremely important in industrial process. This work describes the production process and the isolation of the citrinin (234,6 mg/L) and of the mycophenolic acid (371,2 mg/L) with high purity levels in the process of extraction of a fermentation of 8 and 12 days respectively of a cultivation in liquid in Czapek medium enriched with 0,2% of extract of yeast utilizing the fungi Penicillium Catl1.1 and Penicillium sp. Casp5, isolated of the Coffea arabica L. after asepsis, as well, the development of an analytical methodology to quantify this compounds using the NMR. Additionally, on this work, we describe the isolation and the structural elucidation of an new alkaloid from prodiginine class with modification on ring (C), from an extract produced by Streptomyces violaceusniger violaceusniger actinomycete, isolated as an endophyte from Zea mays L. leaves and identified by Costa (2005), which was able to inhibit the growing of phytopatogens with economic value (Pythium aphanidermatum, Rhizoctonia solani, Sclerotinia sclerotiorum, Phytophthora parasitica e Fusarium moniliforme). Therefore, Finally, due to the results obtained during the execution of this work, is able to conclude that the Nuclear Magnetic Resonance, beyond be presented like an efficient analytic technique in the quantification of the citrinin and of the mycophenolic acid in the extract fungi, was fundamental in the monitoring and optimization of the conditions of extraction during the period of 20 days of fermentation. Like this, to NMR is a technique that will be utilized in the process production and optimization of the substances produced by microorganisms in industrial scale.
