For the planning and environmental monitoring aiming at the conservation, the arthropods are appropriated as indicating species due to its great abundance, morphologic, taxonomic and functional diversities. Despite the potential for the use of Insecta as bioindicators, little attention has been spent to them by biologists, ecologists and taxonomists, not only in the current knowledge application, but also for new methodologies development. For this reason, this study proposal was to evaluate the potential use of the family Braconidae (Hymenoptera: Ichneumonoidea) as terrestrial biodiversity indicator in the State Park of Jaraguá, São Paulo state, Brazil. A multimetric characterization involving the environmental variables (temperature, luminosity and humidity) and biotic variables (vegetation, hosts and parasitoids) were applied in order to characterize the selected microenvironments. The samples of the organisms were obtained in a condensed way in four periods of ten days corresponding to the dry season (November of 1999 and July of 2000) and to the rainy one (March and December of 2000). In order to sample a large local faunistic diversity, three backing techniques of insects collection were used: Malaise traps, Yellow Pan Traps and Sweeping of the Vegetation. The clustering analysis method was applied to evidence the similarity among sampling sites in the dried and rainy periods. Many fast techniques of environment evaluation of quality adopt a multimetric boarding using a set of metric in order to evaluate the environment degradation. In this study we use as metric four categories of variables: variables of parasitoids community structure, ecological parasitoids variables, environmental variables and variables of the floristic composition. The Principal Components Analysis (PCA) was used aiming at evidencing possible standards in the sites of sampling in the different seasons in relation to the metric ones. Were captured 2449 specimens of Braconidae, in which the more collected subfamilies were Alysiinae, Doryctinae and Microgastrinae with approximately 74% of the total sample. The analysis allowed us to verify two groups of habitats, one formed by Sopé and Silêncio and another formed by Zé, Pico and Aloja. The results indicate a difference in the structure of the community, mainly in relation to the sites sampled, suggesting that the different uses of the ground can influence the biotic variables (Alysiinae, Microgastrinae, etc.) and the abiotic variables (luminosity, humidity, etc.). Moreover, this study indicates the potential use of some metric to the evaluation of environmental quality, considering the Braconidae as bioindicators.

This work presents a new concept in Production Management field: Manufacturing Management Strategical Paradigms (MaMSPs). The main MaMSPs are identified: Modern Mass Production (MMP), Lean Manufaturing (LM), Responsive Manufacturing (RM), Mass Customization (MC) and Agile Manufacturing (AM). Relationships between these paradigms and manufacturing strategic goals and between the paradigms and important aspects o Production Control are proposed, providing a strategic approach to Production Management. Regarding each specific paradigm, this work reaches some important goals: it shows that Mass Production is still used in brazilian shoe industry, with some differences regarding Fordism. Relating LM, a literature review on this matter is structured according to four key elements of all MaMSP. Regarding RM, we propose a new methodology for design and implementation of RM. This methodology focuses on Production Control activities, which we consider the key to reach responsiveness. Regarding MC and AM we differentiate these paradigms. This differentiation contributes to diminish some concepts confusion about these paradigms. In this work we also propose two other methodologies: i) to identify the MaMSP used for a company; ii) to identify the most suitable MaMSP for a company. Both methodologies are illustrated in six case studies on brazilian shoe industry. Using both methodologies in a coordinated way provides a correct strategic position for companies. Finally, we conclude that this work contributes with Production Management field through the proposition of some methodologies regarding Manufacturing Strategy and Production Planning and Control.

Nowadays, there is a wide information bulk in accelerated increase that needs high efficiency of analysis to the decision maker. Databases spreading become more important the production of indicators to technological forecasting by using automated bibliometric analysis. Although, the most databases aren t structured for this goal. In this way, it becomes fundamental the data preparation considering the technologies studied, the features of database used and of information retrieved, besides of the programming technologies. In this work, it was developed solutions to increase the efficiency of bibliometric analysis from essential databases in materials science and technology. New solution was developed to the Metadex database that allowed automatic grouping of processes, properties, factors that can influence properties and processes and shape of materials. Also, it was created a new database contained more than 30 millions of restructured records from Web of Science, inserting all the cited authors besides the first (the only one available), classification inserting, improvement of data retrieval and others. Study complementary was developed to improve the Derwent Innovation Index that improved the technological study of different countries. The methods were applied to the forecasting study of hermetic compressor surface treatments. It was possible to create and analyze indicators of the main surface treatment technologies to decrease wear, relations between applications and coatings types, among R&D fields, countries, institutions, companies and renowned researches. Also, the developed methods can be adaptable to as other databases as other technological forecasting studies like materials field or other technological and scientific knowledge fields.

The present thesis investigated the role of coordination and management supply chain in face of identifies no-GM crops and the need to preserve the identity of grains. This change traverses the entire productive chain, from the seeds industry to the final consumer, ever more demanding in terms of issues related to food safety. A new arrangement in the system (Strictly Co-ordination) will be linked to the capacity of the various agents of the agroindustrial systems to coordinate and manage these relationships, mainly by means of the development of mechanisms of incentives and control, including efficient forms of identity preservation (IP), traceability and certification of the product throughout the chain. The latter will play a fundamental role in diminishing the information asymmetry between producers and consumers and valuated agri-food products. The theoretic framework utilized was Transaction Cost Economics, which allowed the foundation and systematization of the analysis, validated by case studies that involved situations of Identity Preservation in Brazil. Thus, four firms that work with non-GM soybeans and utilized segregation systems, incentives and monitoring of crops production were analyzed. It was verified that, indeed, the trend toward product segregation involves the need for adaptations and alteration in the predominating governance form. Identity preservation also involves increased costs, which permeate all phases of the productive chain. These costs are identifiable and have a strong relationship to the characteristics of the transactions and to the attributes of the product one wishes to segregate. The thesis also identified that incentive and monitoring strategies are fundamental for the success of the identity preserved (IP) system. The other relevant aspect was about reputation of the certificated entity.

The fast growing of regional jets market has required from airframe manufacturers a prompt attending to market demands and the primary parts fabrication at a planned quality, quantity, and time at low costs. In order to achieve this, the process robustness is a key concept to be kept in mind, it means that the manufactured parts shall be conform to engineering specifications and geometric tolerances as well, regardless the raw material source used in machining process. Warping or machining distortion is one of the main problems identified during machining process. The corrective action for warping impacts the manufacturing lead-time, production costs, and production plan accomplishment. The influence of raw material on machining process performance is one of the main variables, is an assumption of this work. Recently, studies related to this approach have started and little technical literature is available. Otherwise, the availability of technical literature related to machining parameters, and cutting tools has been exhaustively explored. The aim of this work is to study the influence of material, in specific, the residual stress originated during thermo-mechanical processing of 7XXX series aluminum alloy plates, on warping of primary parts manufactured through milling machining. The layer removal method was the experimental technique chosen to measure the residual stress. Through this method is possible to determine the through thickness residual stress profile, the more suitable information for this study. In addition to this, the W parameter, which gives the average residual stress level per volume unit of plate and is a function of existing residual stress profile was also derived. It was correlated to warping level of machined from plates with several W parameter values. Parts machined from low W parameter values (lower than 1,0 kJ/m3) plates presented warping measurements remarkably lower than measurements made with parts machined from plates with W parameters values higher than 2,0 kJ/m3. This trend agrees with data available in literature and demonstrates the layer removal method results dependability, and its suitability to be applied for suppliers qualification purposes.

This work presents a strategy for transformation of legacies systems write in Procedural DataFlex (DFP), for systems in Objects Oriented Visual DataFlex (VDFOO) reusing a Framework, denominated DataFlex Application Framework (DAF), with architecture in three layers: interface, business rules and database. The transformation is accomplished in three steps: To "Organize Legacy Code", when it happens the organization of the legacy code in DFP; "Reemployments Organized Code" DFP, when the reemployment of the Organized Code DFP for VDFOO; and to Execute the VDFOO Code , when the code is executed in VDFOO with the same functionalities of the legacy code in DFP. The technologies used for the elaboration of this work are presented, involving Techniques for Reengineer, Transformations Systems, Languages Procedural DataFlex (DFP) and Objects Oriented Visual DataFlex (VDFOO) and DataFlex Application Framework (DAF). The Draco-PUC Transformation System is the main mechanism for automation of the transformations. To aid in the definition of the domains in Draco-PUC an editor of denominated domains it was built Draco Domain Editor (DDE), besides the parser and prettyprinter DFP and VDFOO. To automate the step "Organize Legacy Code", the Transformer of DFP was built for Organized DFP, and for the step "Reemployments Organized Code" DFP, the Transformer of Organized DFP was built for VDFOO. DDE is also used to define the script of execution of the transformers. The Transformation of DFP for VDFOO reuse a Framework in three layers: interface, business rules and database. The transformations of two systems are presented: Control of Orders, with about 20 thousand lines of legacy code; and the Integrated System for stores of sale s of cars (SIRC-X), with 5.3 million code lines.

A quali-quantitative survey was carried out in two seasonal semideciduous forest fragments (75 and 100 ha) of interior of São Paulo state. The purpose was to characterize their bird communities concerning richness, abundance and species occurrence in these areas. The qualitative survey showed 145 species at Estação Ecológica de São Carlos-EESCar (Brotas) and 173 at Fazenda Santa Cecília-FSC (Patrocínio Paulista), whereas the quantitative survey revealed the presence of 60 and 72 species at EESCar and FSC, respectively. Only 4,14% of species in EESCar e 20,24% in FSC had specific frequency of occurrence over 75%. Analysing the abundance index values (IPA), we observed that number of species with low IPA was high at EESCar and at FSC. The small size and the isolation at EESCar might be responsible for its low species number IPA. In the FSC was also observed a bigger occurrence of endangered species for São Paulo state. The analysis of guildes is important to indicate the ecological conditions of one fragment. Apparently, the fragment at FSC has a better environmental quality to shelter more species, including the endangered. The study of this bird community is important for the elaboration of the conservation management plan of the natural areas.

A survey of the Braconidae (Hymenoptera: Ichneumonoidea) fauna on northwest São Paulo State fragmentary natural environments was conducted using Malaise traps in five sites of Environmental Protected Area of Descalvado, SP, Brazil. A total of 2262 specimens, representing 22 subfamilies and 94 genera, was recovered throughout a period of sixteen months from may 1999 to august 2000. Biological data were obtained from current literature and behavior patterns of host utilization for the studied fauna, in special the Braconidae which have been successful in control of agricultural insect pest. Statistical analyses indicated that the asymptote of current genera richness has been approached using this sampling method. This is the most complete survey available from natural fragmentary areas of the Descalvado Braconidae fauna. Patterns of distribution and richness of the genera of the Braconidae were recovered. Cluster Analysis was adopted taking as attribute the number of Braconidae genera. The flight phenology of these 22 subfamilies of Braconidae was studied and the trap catch for koinobionts peak was in August, 1999 a month before of the idiobionts peak and in June, 2000 both peaks were simultaneous. The phenological peaks of dominant koinobiont taxa (Microgastrinae) were similar to all koinobionts, and the peaks of dominant idiobiont taxa (Doryctinae) were similar to all idiobionts, as well. February, 2000, was the richer month in number of subfamilies (N= 18), corresponding to the same period when the subfamilies wich potencially attack Lepidoptera where collected. The number of females was superior to the number of males and this relation was more accentuated in koinobionts. The peaks of both females and males were similar to dominant koinobiont and idiobiont taxa. Eight new species of the genus Pseudognaptodon Fischer, 1965 (Hymenoptera: Braconidae: Gnamptodontinae) collected in this study were described andillustrated. These information were used to produce the pedagogic material (CD-ROM) which will be distributed in the schools of Descalvado, SP, Brazil, after the training of the teachers.

Macrophytes have a fundamental role in the functioning of aquatic ecosystems due to their high primary productivity, participation in the nutrient cycling, and interactions with many other components of the system. Many species of macrophytes can be bioindicator of the trophic state or succession stage of the system. In the present work the macrophyte communities of twelve lakes in the Middle Rio Doce (MG) and a cascade of six reservoirs (SP) were analysed, comparing systems naturally and artificially fragmented. Four sampling expeditions to the Rio Doce system and three to the Tietê were performed during the 2001 2002 period. The macrophyte species present were recorded, photographed and collected for herborization. The community was analysed in relation to the species richness, dominant species, the frequence of occurrence and the species composition similarity, intra and inter lake and reservoir systems. The relationship between species richness and lake morphometry was also analised. Macrophyte biomass was determined for selected stands, in order to verify the existence of temporal variations. In the lakes of Middle Rio Doce system a total of 53 species were registered, belonging to 25 genera and 23 families. The occurrence of Habenaria fastor Hoene (Orchidaceae) in this system of lakes was recorded for the first time. The highest richness occurred in the lakes Barra and Verde. Species composition varied considerably among lakes and between periods. No statistically significant relationships were found between species richness and variables related to lake morphometry, although a tendency of increase in the species richness as a function of the increase in the area and perimeter of the lakes was observed. In Tietê reservoirs a total of 48 species were found, belonging to 26 genus and 22 families. The species composition in the first three reservoirs (Middle Tietê) differed from that on the last three reservoirs (Low Tietê). The relationship among the species richness and reservoir morphometry was not statistically significant, however there was a tendency of decreasing richness as the reservoir area or perimeter increased. Twenty three species were shared among both systems; 23 exclusively on lakes of Middle Rio Doce and 18 exclusively in on Tietê reservoirs. The families Cyperaceae and Onagraceae were the ones represented by the highest number of species in both systems. Marked differences were found between the studied systems. The macrophyte species richness was higher in the Middle Rio Doce lakes than in the Tietê reservoirs. In the lakes the increase in the area and perimeter were factors directly related to the increase in species richness whereas in the reservoirs this relationship was inverse. Biomass of macrophytes in selected stands varied greatly between periods, however total biomass per areal unity was similar, although the highest values were recorded in Nova Avanhandava and Ibitinga reservoirs. The results of this study have indicated that the lakes of Middle Rio Doce being a naturally fragmented system, ancient and stable, have a higher macrophyte diversity, whereas the Tietê reservoirs, recently and artificially fragmented and also with greater instability have a lower diversity. Also, the species richness in the reservoirs appeared to be not directly related to the area and perimeter, variables which are representative of their most propitious habitats in natural systems.

The life follows on by the frontier independently from the actions of the State, however its presence is merely to guarantee certain basic conditions of the workers who, voluptuaries or stimulated by the official programs of settling, use to go disclosing the forest and affirming, "unconsciously" the condition of the Brazilian State. The Present work has as object to study the actions undertaken by the Organized Association for Mutual Aid - AJOPAM - in the northwest of Mato Grosso according to what refers to the developed organizational and pedagogical process from 1986, more specifically around those that agglutinated the formation and professional qualification of the agricultural workers, configured as the School of Agriculturists Technician that started working in the 1997. Giving more importance for the professional preparation of the workers, installing some new conceptions and relation between the men and the nature, after all when they transform the landscape imagining that the natural resources will be forever abundant. It has passed less than twenty years of the occupation that was stimulated by the State in the region and what we see is the indifference of the public politics, principally related to the environment which makes us to incorporate it in a different pedagogy of the land, not because of the tendencies of the moment, that could be pos modern, but as a possibility for the future generations to have survival conditions. In this way, the fights of the agricultural workers, women or men, are not established in the contradiction of the way of working but on the forms that it is organized there and that they are results of the workers actions and their social movements like the AJOPAM that shows their new perspectives of working, dreaming, utopias, frustrations and desires to see, in a brief future, better conditions of education, culture, health, transport and social providence.

The emergent technology of software agents is becoming popular in the last years, due to the increasing of Internet applications. Software Agents were initially used to filter information, find people with similar interests and to automate repetitive processes. Nowadays, they are being used in e-commerce applications, making a revolution in the way of leading the negotiations between people and companies. This technology automates several traditional steps of the purchase and sale process for Internet, reducing the costs and eliminating geographical barriers. This research presents a proposal for the development of an E-Commerce Framework, via Mobile Internet, mediated by Software Agents (FCEMAS). The framework is based on project patterns and Mobile Internet solutions using WAP (Wireless Application Protocol).

The current context of the world economy heading for the globalization of markets leads to new approaches of the discussion on the role of the university as an essential agent to the progress of Science and Technology. The discussions have been pointing to the latent potential in the relationship between universities and industries as responsible, in great part, for the technological development of several knowledge areas on behalf of the society and, recently, the public universities are implementing actions that draw more attention to its social role. The objective of this study is to contribute for a better understanding of the matter involving the relationship between the university and the industry in Brazil, through a research accomplished in the Federal University of São Carlos (UFSCar). The choice of this university is justified by the important role that it has been carrying out in the regional context, consolidating, together with the University of São Paulo campus São Carlos, the local Pole of High Technology. Taking as study object the universe of 700 contracts managed by the Foundation of Institutional Support to the Scientific and Technological Development (FAI-UFSCar), it was possible to trace a prospect of the cooperation of UFSCar with its external partners for the period 1992-2000.

In the semi-arid North-east region of Brazil occurs the second highest density of dams in the world (or açudes , as they are locally known) which supply water to ca. 40 millions inhabitants, mainly during the dry period, a catastrophic and frequent event in that Brazilian region. The limnological functioning of such water system in the Taperoá II dam (07o11 44 S and 07o13 44 S, 36o52 03 W and 36o50 09 W) was investigated through sampling carried out between September/1998 and September/2000. Sampling was performed at four collecting stations: three of them at the pond margins and one in its pelagic zone, where four depths were selected: surface, 50% and 1% light penetration, and at 4.0m depth. Climatological characteristics of the region (air temperature, evaporation, winds, and rainfall) were analysed, as well as the physical and chemical properties of the water (temperature, dissolved oxygen, pH, electric conductivity, alkalinity, turbidity, transparency, total dissolved inorganic carbon, ammonia, nitrite, nitrate, total phosphorus, orthophosphate, and silicate). Climatic variations due to El Niño event (1997-1998) caused, between September/98 and January/99, a drastic reduction of the available stock of water in the pond, which determined a strong concentration of dissolved salts, an alkaline pH, high electric conductivity and high inorganic nutrient contents. The diluter effect of the increased rainfall in February and March/1999 exerted a reduction of oxygen, conductivity, and dissolved nutrients and caused water acidity. The recovery of the pond hydrometric volume and its stability, maintained the limnological variables almost unchanged up to the next rainy period. A relative thermal stratification occurred between February and April/2000 simultaneously to a chemical stratification. The Principal Components analysis allowed to distinguish the system based on the highest limnological variables here studied and the water volume fluctuation, showing that the interaction of extreme dry season and rainfall in a short period, are the strongest determinants of the high interannual variability of the sampled variables and of the reduced spatial oscillations of the horizontal and vertical axes of the dam.

This work has as starting point the question: How do female teachers of first graders at Elementary Schools perceive the construction of their conceptions and experiences concerning, specifically, their work with sexuality and gender relations that are present in classrooms and other school premises ? Its objectives were to identify through interviews with female teachers: a)the perceptions about the course of their professional formation; b) their perceptions about sexuality and gender relations present in the interpersonal relations in the classroom; c) perceptions of ways in which they themselves deal with questions related to gender and sexuality; d) conceptions that enter their perceptions (or their absence) about sexuality and gender relations of their male and female pupils; e) their personal conceptions of sexuality and gender relations that influence their perceptions and conceptions of sexuality in infancy and gender relations; f) how their conception interferes with the relations that they establish with their male and female pupils and which they let these establish with them. To collect data two female teachers of local State schools in São Carlos, State of São Paulo, Brazil, were interviewed. Analyzing their testimony resulted in three thematic focos, which are: the formation and the pedagogical experience; b) the male and female pupils and the female teacher: perception of gender relations present at school; c) sexuality present at school. The results of the research confirmed that the school provides its pupils with Sexual Education, ruled by sexist stereotypes and by hiding the infantile sexuality, as already disclosed by extensive literary work about this subject.. Analyzing the interviews of the female teachers also demonstrated that they perceive that their conceptions originate , to a large extent, in multiple factors, among others, the home education, which they received during infancy, and which was heavily influenced by Christianism, predominantly Catholicism. The media, represented by television, but mainly by magazines for adolescents, also took part in this construction, giving information nor always available through family or friends. The data also revealed that the teachers training courses only superficially approach the human sexuality question without special attention to the infantile sexuality. Moreover, the interviews disclosed that the school educators visualized very little, and in an intuitive and spontaneous way, the sexuality of their male and female pupils, as well as their manifestations. Finally, these female teachers said to believe in the importance and in the necessity of a formal Sexual Education in the school curriculum with teachers specially prepared for this task.

Stomatal density and leaf porosity of twenty woody species of cerrado vegetation. In this work was characterized the size, and density of stomata and leaf porosity of twenty woody species found in a cerrado vegetation located in the forest reserve of the Federal University of São Carlos SP. It was used paradermic cuts of mature leaf without tricomes. These cuts were observed in a microscopic acoplated a personal computer and stomata was counted and sized for the Image Plus program. The Casearia sylvestris presented the highest estomatal density: 602/mm2 in inferior surface and 316 /mm2 in the upper surface, however it presented the lesser average area of the stomatal porosity around 18.7 µm2 and 1.29% of total leaf porosity. The Kyelmeiera coriacea was placed in the other extremity of the stomatal density with 80/mm2 in the inferior surface of leaf and 43/mm2 in the upper surface. This species presented an high average of area pore, around 102 µm2 and total leaf porosity of 1.09%. The total leaf porosity for the studied species are distributed between 0.75 and 2.63% of the leaf surface. The Rapanea umbellata presented the biggest total leaf porosity for the group of twenty analyzed species, being around 2.63%, 230/mm2 for stomatal density and with 114µm2 of total area of pores. In the other extremity the Rapanea lancifolia presented the lesser leaf porosity, around 0.75% , 252/mm2 of stomatal density and 29.7µm of total area of pore. The results were analyzed in function of strategic adaptation of species to the hydric deficiency of cerrado biome.

The present work consisted in the application of a method for environmental sustainability analysis for land use and soil occupation of Ilha Comprida city, located in the southern state of São Paulo, the estuarine-lagoon complex Iguape-Cananéia- Paranaguá, region of Vale do Ribeira de Iguape. Land use and soil occupation of Ilha Comprida and the concept of sustainability as a theoretical, technical and empirical supporting body were studied. This work used a methodology based on a Method developed by a Study Group from UFSCar (Federal University of São Carlos) called Strategic Planning and Sustainable Urban Environment (PESMU), which incorporates the sustainability issue in the analysis and evaluation of urban context projects. Therefore, the methodology makes use of flow charts, interaction matrices, characterization sheets, used together, directing the analysis of environmental sustainability in the city, pointing favorable, neutral or unfavorable trends to environmental sustainability. Practical applications of the method in different areas of the city were carried out, showing the land use and soil occupation as the action variable (street construction layout, plot, deployment of building plots, urban uses and buildings geometries) and environmental issues as control variables. Comprising an easy applicability methodology, it proved to be feasible, and can be added other possible information and more complex analysis tools to enable the expansion of its applicability.
