This research aimed to study the activity of the HLB's scouts, workers whose function is to identify symptomatic plants, in order to understand the physical constraints, cognitive and organizational involved in accomplishing the task, characterizing the operative approach used to identify diseased plants, and to elucidate what aspects hinder the identification of symptoms. The method adopted for the research was the Ergonomic Analysis of Work EAW (Güérin et al., 2001). The results, after validation with the operators and management, allowed understanding the complex relationships between the physical, cognitive and organizational aspects present on activity. Major difficulties were observed mainly in relation to the disposal of the scouts on the platforms and in relation to working hours, at the beginning and end of the journey. Important findings have highlighted strategies, unknown by the organization, used by scouts to locate candidates‟ trees to the fine analysis of investigation of symptoms. In conclusion, the analysis enable to understand the constraints and find technical and organizational solutions to the survey work on citrus groves as well as it showed signs and symptoms not investigated yet or rarely considered by researchers involved on searches aimed at increasing the ability to diagnose the disease in the field.

The Product Development Process (PDP) is a critical process because it is subject to innovation and competitive strategy of companies. The furniture industry of the micro-region of Votuporanga, consisting primarily of micro, small and medium sized companies is relatively new, and has a significant weight in the local economy, generating jobs and income. This research studies the PDP in the furniture sector of the micro-region of Votuporanga, placed in a cluster with the aim to identify the essential properties of this business process in order to establish its dynamic, technological and managerial vulnerabilities and strengths as well as the future prospects of the sector for meeting the challenges of competitiveness and innovation policy. From the scientific point of view, it draws a parallel between the theory and practice of product development in companies with limited manpower and financial resources. Thus, it considers the activity of the product development process in the context of the furniture industry as a study to attempt to confirm or refute hypotheses about the characteristics of PDP in small Brazilian companies. The descriptive and exploratory survey method was applied by a structured questionnaire with closed questions. The research instrument was developed and validated in a pilot study of ten companies. Statistical techniques were used to select the sample and analyze the data due to the large number of variables studied, so the statistical tools recommended and used were the descriptive and multivariate techniques. It was possible to confirm the weakness of the organizational structure of SMEs from the analysis and the constructs examined, wich generally adopt non-formal and imitative strategies with centralized administration based on owner s control. The success of the new product introductions depends on the tacit experience of those involved in product development.

Marketing and Logistics have a high need for integration because they compose contact points that influence the synchrony of operations with market needs. The literature in this area predominantly focuses on the elements that generate integration, and the correlation of those elements with functional and organizational results. However, there is a theoretical gap related to the characterization of the inter-functional integration dynamics between Marketing and Logistics and the integration elements. This research aimed to characterize the interfunctional integration dynamics between Marketing and Logistics. The elements that compose the integration dynamics are identified and characterized. The key elements related to inter-functional integration dynamics that were identified in the literature include contact points, integration factors, integration level, formality/informality of integration processes, and integration impacts. In order to better characterize these elements, five case studies were conducted in manufacturing companies, from different industries: Chassis and Wheels, Agriculture Chemicals, Beverages, Soybean Oil and derivates, Oral Care Products. The indepth interviews considered both Marketing and Logistics perspectives. The analysis identified similarities and differences in the characteristics of the Marketing and Logistics inter-functional integration dynamics. Practical definitions were established for contact points, integration factors, integration levels, integration formality/informality, and impacts generated by integration. The investigation of these elements within organizations may facilitate integration efforts between Marketing and Logistics, reducing conflicts and improving the companies' performance.

The growth of passengers air transport as well as the competitiveness of the aviation industry have made the comfort a noticeable item to be taken into account, which is characterized as a key variable for the cabin project and also for the differentiation in the market, once it is related to the passengers satisfaction and acceptance when it comes to this transportation modality. In this context, the in-flight entertainment has been considered one of the most relevant requisite in order to improve the comfort while in the cabin in a way that it enhances values of the airline companies, contributing for a more pleasant and also a rather positive air travel experience. Thereby the aim of this study is to understand the aspects of either comfort or discomfort in airplane cabins, exchanging views on the importance of entertainment activities on board as well as their influence on comfort and discomfort in the cabin. Firstly, based on the literature review it made possible to clearly understand the concepts of comfort and discomfort including the current possibilities of in-flight entertainment. Considering comfort as an outstanding and suitable point to be applied in the cabin, this study is grounded in the approach of the analysis of the activity. As such, the data collection was implemented in two contexts: survey of Brazilian commercial aviation (airports and domestic flights) and interviews with companies connected with the entertainment industry and air transport sector. The procedures adopted have permitted to identify the active travellers preferences and expectations when it comes to in-flight entertainment, what is more, the constraints during the activities occurred in the cabin and tendency of the industry in question. Some recommendations for the project were made, highlighting, mainly, the importance of the amenities in the aircraft cabin for the travelers to use their own devices during the flight.

In this research, we study lot sizing problems with decisions on product distribution and, also, problems that integrate lot sizing decisions and product packing in the vehicles (bins). In general, these problems involve a trade-off among production costs, holding costs and distribution costs. The lot sizing problems consider limitations in the production capacity and demand delivery deadline. The distribution decisions are related to the product loading into the unit load device (pallets, containers or trucks). The packing problems may involve one, two or three dimensions relevant to the product loading. The problems are modeled by mathematical programming and solved by the branch-and-cut method of an optimization package, and then, the performance and the results obtained are analyzed. Furthermore, heuristic methods are specifically developed in order to provide an approximate solution for these problems. The heuristic methods are built according to the lagrangian relaxation and ant colony optimization. All the methods are tested and evaluated, regarding the solutions found by the optimization package for the proposed models.

Stainless steel has been the subject of numerous studies due to technological and economic importance. Features such as durability, corrosion and high temperatures resistances confer to the steel relevant applications in several industrial sectors. Thus, the study of methodologies for chemical and electrochemical polishing, instead of mechanical polishing, has been increasing due to improved surface quality of these steels by not introducing contaminants and/or tension in the superficial layers of the metal, making them microscopically smooth, passive and anticorrosive. Therefore, in this work, the process of electrochemical polishing of AISI 304 stainless steel in solutions of concentrated sulfuric acid (H2SO4 also used in the coloring process of these steels) and phosphoric-sulfuric mixed acids (H3PO4 and H2SO4 2:1) containing glycerol was studied using the galvanostatic method (constant current). Factorial design was used to optimize the main process parameters such as concentration of the acid solution, current density, temperature, electrolysis time and additive content. The surface quality of steel samples was evaluated by spectral reflectance. Some steel samples electropolished or not (steel samples as received) were also characterized by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The statistical model generated for the electropolishing process of steel in solution of H2SO4 did not fit well (R2 = 0.75) to the experimental results. Among all the electrolysis, the one that produced a steel surface with the highest percentage value of reflectance (R = 71%) was performed in the following experimental conditions: [H2SO4] = 9 mol L-1, i = 0.6 A cm-2, θ = 55 ° C and t = 7.5 min. In these conditions the corrosion rate of steel samples was 0.33 mm h-1 and the process energy consumption was 3.0 kW h m-2 for an average cell potential of 4.0 V. On the other hand, the statistical model generated for the electropolishing process of steel in solution of H3PO4 and H2SO4 2:1 containing glycerol fitted reasonable (R2 = 0.93) to the experimental results. The punctual optimal conditions were: H2SO4 and H3PO4 2:1 containing 25% glycerol and kept at 30 ° C, i = 1.0 A cm-2 and t = 8 min. In these conditions, the surfaces of the steel samples showed R values of 70 %. The corrosion rate of steel samples was 0.19 mm h-1 and the process energy consumption was 23 kW h m-2 for an average cell potential of 17 V. From AFM images, the calculated values of average surface roughness factor (Ra) were 139 ± 20 nm for steel samples as received (R = 58%) and between 20 and 75 nm for steel samples electropolished. The SEM images for these latter samples revealed the different crystallographic orientations of the AISI 304 austenitic stainless steel.

The influence of subsurface dams in semi-arid agro-ecosystem sustainability must be studied from a systemic perspective to evaluate the dynamic sociopolitical, cultural, economic and environmental involving farmers as actors in the research. The farmers also perform the non-agricultural activities seeking to generate more income for the family, and thus enable social reproduction, economic and environmental, not taking away its rural identity. We used qualitative methods based on participation facilitated by the tools of methods Participatory Rural Appraisal - PRA and the Evaluating the sustainability of Integrated Peasantry Systems MESMIS Framework, in order to assess the sustainability of two properties with subsurface dams in semiarid region of Paraíba State, Brazil. It was found from the perception of families, the 01 Property, Family Santos, got a reasonable level of sustainability (3.1), from the average 3.4, 2.8, and 3.0 obtained for the dimensions environmental, social and economic, respectively. While 02 Property, Family Lira reached a good level, with overall mean 4.1, obtained through the medium, 4.1, 4.2 and 4.3, for environmental, social and economic, respectively. Quantitative indicators for the assessment of physical, chemical and biological soil proved to be efficient in comparison with subsurface dam environments (BS) under the conventional system and native, were observed higher levels of OM accumulation in the area of the BS and increased microbial activity in the native forest. The families participating in the study, although they are soon in the process of agroecological transition, progress toward a more sustainable agroecosystem, and the subsurface dam as a potential technology to improve and balance the ecological processes of the production system of family farming semiarid.

This doctoral thesis has been developed in order to identify the ethical aspects of research in education, considering the 196/96 National Health referred to the guidelines and standards regulated research involving humans. To make it possible to perform this task and establish the theoretical research we used the reflection on the concept of ethics and ethics in life science research. The methodological approach was based on bibliometrics that were used to analyze the scientific production of 73 theses and dissertations in the Graduate Program in Education (PPGE) of the Federal University of São Carlos (UFSCar), between January 2009 and December 2010. This historical period was chosen because of the concern in describe and discuss the ethical aspects of research produced in the first decade of this century, and questionnaires, with a former student and three teachers linked to the Program. The results of bibliometric analysis allowed to verify that participants were 2606 of these dissertations and theses and that 74% of the studies analyzed (21 theses and dissertations 33) were not submitted to the Ethics Committee. Analysis of the questionnaires revealed that participants are aware of the demands of ethical commitment in conducting research, but in different degrees of depth, particularly with respect to the contents of Resolution CNS 196/96. Participants also agreed on the need for further clarification on the ethics of research to graduate students, and emphasized that the bureaucratic aspects surrounding the submission of research to the Research Ethics Committees, often away from the researchers. Finally, it was observed that the participants consider that studies performed in this field of knowledge does not pose risks to the participants surveyed, which points to the importance of building a culture of bioethics needed for academic and professional researchers in education, because all intervention research entails risk to the participant, and for small or rare they are, must be provided.

The taxonomic classification system of all organisms has been traditionally based in the comparative analysis of a wide range of morphological structures. In the last decades, the potential of physiological, cellular and molecular characteristics have been recognized in taxonomy, including phylogenetic and biogeographic aspects. This study focuses on the structural and evolutionary characterization of a region encompassing the 3 end of the mtDNA gene COI from sarcophagids and analyzed the contribution of this information for species identification, increasing the knowledge related to this family in the neotropical region. The Sarcophagidae family has approximately 2,600 species and their phylogenetic relationships are not well established for most genera and sub-genera. In this scenario, the characterization of nucleotide sequences for species identification in Sarcophagidae is a strategic approach that contributes for inferring phylogenetic relationships in this family. In this study, a 470 bp region from the COI gene was sequenced and characterized by structural and evolutionary analyses for five species: Peckia anguilla, Peckia collusor, Peckia ingens, Oxysarcodexia admixta e Oxysarcodexia paulistanensis. For comparative analyses we included ortholog sequences from three other sarcophagid species (P. intermutans, O. ventricosa e S. carnaria) and from the species C. hominivorax (Calliphoridae) e Haematobia irritans (Muscidae) available in GenBank. The intraspecific variation showed values between 0 e 0,01 and the interspecific variation varied from 0,07 - 0,151. Similarly to other Diptera families, the nucleotide composition of this region showed a high content of A and T (on average: A = 30.2%; T = 38.7%; C = 17.3% and G = 13.8%). The aminoacid composition presents higher abundance of Leucine, Phenylalanine and Tyrosine. Only eight divergent aminoacid positions were identified in comparative analysis of sarcophagid species, in addition to 3 positions that diverges from the insect COI protein structural model. Neighbor-joining analysis using Kimura-2P, an usual procedure in DNA barcodes analysis, distributed all species in monophyletic clusters, however the utility of this approach for resolving taxonomical conflicts requires additional sampling of specimens/species including a wide geographical coverage in order to provide a better characterization of intraspecific variation in these species.

Middleware for interactive digital TV systems are designed to provide convenient abstractions to overcome differences of hardware/software in order to improve the portability of applications. The development of a middleware implementation from scratch is a complex and costly task. To minimize this effort, software assets of existing implementations of these middleware can be reused through software reuse techniques. A refactoring process can be applied to existing middleware implementations to improve some software requirements such as modularity and reusability, in order to facilitate reuse of the middleware. This work presents an approach of refactoring focused on portability as a reuse strategy for the development of new instances of a digital TV middleware for new hardware platforms. The proposed approach is based on software portability concepts and construction characteristics of digital TV middleware. To evaluate the work, we present a case study with our experience of refactoring an implementation of the Brazilian digital TV system s middleware.

The present work is aimed at exploiting the relationship between city and work, from the study of two democratic experiences: a self-managed joint effort (mutirão) and a community bank in the city of Sao Paulo. These two experiences show us that the social movements constantly need new ways of carrying out their actions in order to renew participation and strengthen the social organization towards the creation of a political community. Both the community bank, that broadens the range of the discussion on the endogenous circulation of money and on the possibility of higher consumption in the area, and the self-managed joint effort (mutirão), which intensifies the access to rights and to participation, are, however, experiences that struggle with huge difficulties and are perhaps weak as alternatives to the capitalist processes of sociability. In spite of that, they show themselves to be, in the very core of the system, capable of transforming previously precarious realities.

The literature points that the identification of problems related to infant mental health and the processes involved in its occurrence is important because it enables a better understanding of this population s reality regarding this special condition, as well as it supplies elements for reflections, planning and implementing public health policies, education, and social assistance which aim infant mental health promotion and can supply the presented demand in a more effective way. Additionally, studies have indicated that the risk factors present in the environment in which the child lives at, as well as the family s social-economical situation, family s structure, parents mental health, parenting styles, among others, are the most influential in the development of problems related to infant mental health. In this direction, the present study has as objective to assess the prevalence of mental health problems in students of the first cycle of the primary education, and the risk and protection factors represented by the variables social support of the responsible person, parenting practices and styles, mental health of the responsible person, and variables related to the family s structure and the context associated to them. There have been 321 participants who were responsible for children studying from the first to the fifth grade of elementary schools of the municipal network of the city of São Carlos. The measuring instruments were: Activities of Daily Living Questionnaire (ADLQ); Brazil Economic Classification criteria (CCEB); Strengths and Difficulties Questionnaire (SDQ); Social Support Questionnaire (SSQ); Parenting Styles Inventory (PSI) and Mini International Neuropsychiatric Interview (MINI). The collected data was analyzed from the spreadsheets of each instrument and the descriptive, comparative and correlational statistical studies. The results found indicated a rate of infant mental health prevalence of 43%, and that 63% of the responsible people have at least one mental disorder assessed by the MINI. Regarding the potential risk factors identified in the present study, it has been observed that infant mental health has been significantly related to the variables: risk practices and styles, responsible person presenting at least one mental disorder, and the existence of fights within the family. Regarding the protection factors, the variable existence, in the family, of responsibilities and rules that all members acknowledge and comply has been associated to the pro-social behavior of the SDQ in the general sample. Besides that, in the family groups that experience two or three risk factors identified in this study, the satisfaction of the responsible person with the perceived social service has been identified as a potential factor of protection for the children s mental health. The results were discussed under the light of the factors theory and mechanisms of risk and protection of infant mental health. It is pointed out that the findings of this investigation contribute for a better understanding of the mental health situation of school-age children, as well as it signals factors of risk and protection, indicating important matters to be considered by the public policies of health, education, social assistance, and other ones which can deal in a more effective way with this reality.

With the increased interest in growing native fish species the tetra has been highlighted nationally in the marketing of fish facing the two niche markets: as a snack in bars and restaurants and other natural bait for sport fishing. Therefore, studies on the stocking density are needed for better understanding in response to performance than can affect the growth, nutrition and animal behavior. This study aimed to evaluate the economic viability and growth performance of the tetra (Astyanax altiparanae) in cages, subjected to different stocking rates. The experiment was conducted on the premises of the UPD Pirassununga, APTA Pole Central East, in cages of 1m3, villages in densities: 250,450 and 600 fish per tank with 4 repetitions. The temperature, water clarity, dissolved oxygen an pH were daily measured. The tetra were fed extruded commercial diet containing 36%of protein. The experiment lasted 57 days and monthly samples were collected to evaluate the development and adjust amount of feed. To verify the significance between treatment means was used Tukey s test at 5% probability. The results showed increasing linear effect for variable total biomass (p<0,05) as opposed to the linear effect (p<0,05) for average consumption of feed as well as weight gain, average final length and final weight medium according to the increase of stocking density. The physic-chemical parameters remained at adequate levels. It is concluded that stocking density affects the development of juveniles of tetra and the density of persons over fishes/m³. Can still be used in the cultivation of 600 fishes/m³ tetra juveniles in cages, resulting in higher total biomass, although they result in smaller populations.

Embedded systems (ES) has become more important to everyday life due to technology advance and increasing application field. Engineers start ES development using tools like Matlab/Simulink. Usually, Simulink models are low level abstraction models following an ad-hoc design, which difficult the model comprehension. Hence, new trends start to apply software engineering to support ES design. Goal: This work was developed in a research group that is defining a development process to support ES development from initial phases to Simulink models implementation. Particularly, this works goal is to explore UML Statchart technique to depict Simulink models in a high level abstraction view, and become the group s desired component part of the process. Method: The investigation process was conducted in three actions exploring UML Statchart based in the Research Action methodology: (i) a reengineering activity starting from Simulink model; (ii) a forward engineering starting from a requirement document; and (iii) a survey investigating the use of UML Statechart by ES developers. Outcomes: The first and second action showed that UML Statechart is an appropriated technique to depict the application behavior, contributing to implement Simulink models. It also organizes Simulink models and facilitates the system comprehension as a whole. Conclusion: Due to the conducted actions outcomes, UML Statechart can be considered as a candidate to compose one of the artifacts to be implemented during the process that is being defined by the research group. However, this work conducted investigations are limited to two system applications, needing to accomplish more complement studies, we can say that Simulink models implemented with support of UML Statechart, are better structured and more comprehensive. This features an increasing quality in ES design.

Locus coeruleus (LC) is considered as a chemosensitive region to CO2/pH in mammals and amphibians, mainly its noradrenergic neurons. The LC purinergic neuromodulation is of particular interest since adenosine 5′-triphosphate (ATP) acts as a neuromodulator in many brainstem areas involved in cardiovascular and respiratory regulation, which includes Locus coeruleus (LC). ATP acting on LC P2 receptors influences the release of noradrenaline (NE) and the LC noradrenergic neurons are involved in the CO2-drive to breathing. Thus, the goal of the present study was to investigate the role of purinergic neuromodulation in the LC in the ventilatory, thermal and cardiovascular responses during normocapnia and hypercapnia in Wistar male unanesthetized rats. We assessed the purinergic modulation of cardiorespiratory and thermal responses by microinjecting ATP P2X receptor agonist (α,β-MeATP, 0.5 nmoL/40 nL and 1 nmoL/40 nL) and P2 receptor non selective antagonists (PPADS 0.5 nmoL/40 nL and 1 nmoL/40 nL; suramin, 1 nmoL/40 nL) into the LC. Pulmonary ventilation (VE, plethysmography), mean arterial pressure (MAP), heart rate (HR) and body core temperature (Tb, dataloggers) were measured before and after unilateral microinjection (40 nL) of α,β-MeATP, PPADS, suramin or 0.9% saline (vehicle) into the LC during 60 min normocapnia or 30 min period of 7% CO2 exposure followed by 30 min of normocapnia. Under normocapnic conditions, α,β-MeATP did not affect any parameter, whereas PPADS decreased respiratory frequency (f), increased MAP and HR and suramin increased Tb, MAP and HR and did not change ventilation. Hypercapnia induced an increase in ventilation, a fall in HR and did not change Tb in all groups. During hypercapnia, α,β-MeATP produced a further increase in ventilation and did not cause changes in cardiovascular and thermal parameters, PPADS caused an increase in MAP, did not alter ventilation and Tb and suramin elicited increases in ventilation, MAP and bradycardia and did not change Tb. Thus, our data suggest that purinergic neuromodulation in the LC plays an important role in the cardiorespiratory control during hypercapnia and modulates cardiorrespiratory and thermal control during normocapnic conditions in unanesthetized animals.

The influence and status that the purchasing function has gained in manufacturing companies are not reflected in the literature related to aircraft manufacturers. There are few studies that adopt, in this environment, the analysis of the purchasing function as the central theme of research. Particularly, there is a lack of studies on the challenges and problems it faces. In order to provide a contribution to this theme, an exploratory case study (single) in an aircraft manufacturer (Embraer) has been carried out aiming to identify the challenges and problems generated in its purchasing function due to the influence of the supply chain, the product (aircraft) and the dynamic environment in which the aerospace industry operates, and to analyze how they should be faced, considering the Supply Chain Management (SCM) approach and the supply chain flexibility concept. The following challenges and problems were identified: changes in customer purchase orders and in the aircraft manufacturer production plan; risks of harmed relationships with suppliers and lack of suppliers confidence on demand information; product changes; customization; late configuration; geographical dispersion and physical distance from suppliers; material acquisition lead-times; increase in production rate; disputes among customers for suppliers limited resources; bargaining power of suppliers; some potential sources of material shortage. The strategies to face them were defined based on the SCM elements (supply chain overall operational efficiency, process integration, information sharing, strategic alignment, and relationship among companies) and the supply chain flexibility dimensions (organizational, supply, market, logistics, information systems, and operations). The results reveal the importance of SCM and supply chain flexibility for the purchasing function and, by extension, for an aircraft manufacturer and the aerospace industry. They also show that SCM and supply chain flexibility can be used in a complementary and convergent way. Although the purchasing function stands at a privileged position regarding the potential of influence over business competitiveness, in the case of an aircraft manufacturer that position is also very challenging. As the aircraft manufacturers are driving their focus to some specific competencies, the challenges and problems analyzed in this research drive the purchasing function to prioritize competences related to the design and management of the supply chain.

The debate about the youth in the last decades has increasingly boosted the inclusion of this topic in the country political agenda as well as it has reinforced the need of understanding that the Brazilian youth is not homogeneous and it lacks further development in the social, cultural, and economic sectors of specific policies to that category. In that context, the Brazilian rural youth present themselves as a distant and invisible category from the urban youth. Besides the invisibility of the agrarian reform subjects, concerning the concrete needs and problems that involve them, there is also a distancing from the public policies in the agrarian reform settlements. Thus, the present research aimed to identify the public policies formulated to the rural youth within the State, and understand the impacts of their deployment in the youngsters lives in Sepé Tiarajú settlement, which is located in Serra Azul/SP. Based on conducting a bibliographical research, semi-structured interviews, and direct observations, it was possible to notice that the youth in the settlement are invisible to those involved in the organizational process, as well as the existing public policies are distanced from the reality of the settlement. Although the settlements are near the cities, the reality of rural settlements has its own peculiarities regarding its organization and relationship to the existing social movements in those spaces. Education, work, and leisure-time activities are among the issues that most concern the youth and their families.
