Humor na propaganda brasileira : um panorama do cômico na criação publicitária nacional

Monografia (graduação)—Universidade de Brasília, Faculdade de Comunicação, Departamento de Audiovisuais e Publicidade, 2013.Pode-se considerar o humor um dos diferenciais da propaganda brasileira, possuindo seus diferentes tons aplicados a campanhas reconhecidas internacionalmente. Apesar de sua contribuição na propaganda nacional ao longo de décadas, não há estudos aprofundados acerca da utilização do humor como recurso persuasivo em campanhas publicitárias no Brasil, tampouco de seus resultados e modos de aplicação. A partir da percepção dessa possibilidade de pesquisa, realizou-se um trabalho monográfico que empregou pesquisas quantitativas e qualitativas para traçar um panorama da utilização do cômico na propaganda nacional. Por meio de pesquisas bibliográficas e, principalmente, análises de conteúdo foi possível identificar algumas campanhas que utilizaram aspectos humorísticos e se demonstraram representativas para elaboração de um estudo de caso sobre esse recurso persuasivo. Por fim, foi possível identificar tendências da utilização do humor na propaganda nacional a partir do panorama histórico construído, assim como sua aplicação na criação publicitária. ____________________________________________________________________________ ABSTRACTThe humor can be considered as one of the differentials of the Brazilian advertising, being its different types applied in recognized internationally campaigns. Although its contribution in the brazilian advertising throughout decades, there are no studies deepened concerning the use of the humor as persuasive resource in advertising campaigns in Brazil, neither of its results and ways of application. From the perception of this possibility of research, a monographic work was done that used quantitative and qualitative research to trace a panorama of the use of humor in the Brazilian advertising. By means of bibliographical research and, mainly, content analyses were possible to identify some campaigns that had used humorous aspects and if they had demonstrated representative for elaboration of a case study on this persuasive resource. Finally, it was possible to identify trends of the use of the humor in the Brazilian advertising from the constructed historical panorama, as well as tracing trends for application of this resource in the advertising creation

Análise da exposição à vibração de corpo inteiro em harvesters de esteiras e pneus na operação de desbaste

No Brasil, pouco são os estudos relacionados a exposição ocupacional à vibração de corpo inteiro em postos de trabalho de máquinas florestais e, quando consideradas operações de desbaste, não há estudos relacionados. Este estudo foi realizado na região de Bituruna-Pr, em povoamentos de pinus taeda com 10 anos de idade submetidos ao primeiro desbaste, objetivando quantificar os níveis de vibração a que estão expostos os operadores de dois tipos de harvester – esteiras e pneus – durante a jornada de trabalho. Utilizou-se um medidor integrador triaxial Bruel e kjaer modelo Type 4447 e os resultados analisados conforme os critérios estabelecidos pela NHO 09. O harvester de esteiras apresentou resultados de aren e VDVR equivalentes a 0,6 m/s² e 11,2 m/s1,75 respectivamente, enquanto o harvester de pneus apresentou valores médios de 0,4 m/s² e 9,3 m/s1,75. Os resultados indicaram diferenças significativas pelo teste t (

VISIBILITY AND POSTURE OF OPERATORS IN HARVESTERS WITH LATERAL AND FRONT COUPLING CRANES

In mechanized timber harvesting operations, it is possible to verify ergonomic inadequacies, such as poor visibility and inappropriate postures, which can cause risks to the safety and health of workers, with effects on the operational performance of the machines. In this context, the objective of this work was to evaluate the effects of the positioning of the coupling crane in harvesters concerning the visibility and postures of forestry operators. For this, the study was carried out in clear-cutting operations in eucalyptus stands, evaluating a harvester with a frontal coupling crane and another with lateral coupling, as well as operators per machine. To determine effective times and typical postures, filming and freezing of images were performed. Then, the Skogforsk and Rapid Upper-Limb Assessment (RULA) methods were used to assess visibility and posture, respectively. Angulation and posture data were compared between machines by the Student's t test. Front and side visibility remained within acceptable limits, but the side crane harvester required operators to have an average head tilt angle of 15º, 50% higher than with the front crane. Consequently, in the postural evaluation, the one with the lateral crane presented score 3 and action level 2 86% of the time, suggesting further investigations, while the other presented score 2 and action level 1 81% of the time, being acceptable if not maintained or repeated for long periods. Therefore, the positioning of the crane coupling on the machine requires a reorganization of the workstation, mainly the machine's display

Hybrid Algorithm based on Genetic Algorithm and Tabu Search for Reconfiguration Problem in Smart Grid Networks Using "R"

Reconfiguration of distribution networks aims to support the decision support, planning and/or real-time control of the operation of the electricity network. It is accomplished modifying the network structure of distribution feeders by changing the sectionalizing switches. Ensure higher levels of continuity and reliability to the electricity supply service are some of the requirements of consumers and electric power providers in the Smart Grid (SG) context. The goal of this paper is to propose a hybrid algorithm (Genetic and Tabu) for the reconfiguration problem based on " R " in order to better support the decision making process. Beyond that, " R " modeling of electricity networks improves the response time when handling issues of network reconfiguration using graph theory. The status of switches is decided according to graph theory subject to the radiality constraint of the distribution networks. The algorithm is presented and simulation results of IEEE 16-bus system, showing good results and computational efficiency

Photocatalytic foams for water treatment: A systematic review and meta-analysis

Photocatalysis has proven to be highly effective for the removal of recalcitrant organic micropollutants at the lab scale. However, drawbacks such as the need for downstream removal of nanoparticle slurries and low surface areas of immobilised catalyst have, so far, hindered large-scale application. Photocatalytic foams have the potential to address these issues and advance the field towards large scale deployment. This review offers the first comprehensive overview of the state-of-the-art in this growing research field while simultaneously addressing two key issues which are slowing down further progress: The lack of classification nomenclature for foams, particularly regarding pore size and production method, and the use of kinetics as the defining feature of a photocatalyst, when alternate figures of merit, such electrical and quantum efficiencies, may be more appropriate. These were particular evident from a semi-quantitative comparison of the literature reported here, which highlighted the need for standardisation of experimental methods within the field. Finally future perspectives and best practices are discussed and recommended

OPERATORS EXPOSURE TO WHOLE-BODY VIBRATION WHILE PERFORMING FOREST SOIL PREPARATION BY BULLDOZER AND HYDRAULIC EXCAVATORS

The levels of exposure whole-body vibration (WBV) while performing mechanized soil preparation operations are concerning due to the exposure time of operators at their work stations, adverse terrain topography, and types of wheels on the machines used. Thus, this study aimed to evaluate the exposure to WBV in bulldozers and hydraulic excavators in performing soil preparation for forest plantation in order to identify possible ergonomic problems and propose improvements in working conditions. The study was carried out in Paraná State, Brazil, in a Eucalyptus urophylla × Eucalyptus grandis stand hybrid, being registered with use of a vibration meter and triaxial accelerometer coupled to the seat of the machines, the resulting acceleration to normalized exposure (aren) and the resulting vibration dose (VDVR) for a period of 8 working hours, following the Occupational Hygiene Standard 09. The results showed aren and VDVR values of 1.0 m s-2 and 18.3 m s-1.75 in the bulldozer, while in the hydraulic excavator it was 0.7 m s-2 and 13.5 m s-1.75, respectively, with a statistically significant difference between the machines by the Wilcoxon test for independent samples (α ≤ 0.05). The WBV levels were above the action level and below the exposure limit in both machines, with the bulldozer showing values above the uncertainty level. Therefore, substituting machines specifically designed for soil preparation and improvements in work organization are measures indicated to reduce ergonomic problems

QUALIDADE DA ÁGUA DO ARROIO OLARIAS E SEU IMPACTO NA REPRESA PROJETADA

In Ponta Grossa city, in the attempt of revitalization of some spaces, start the construction of dikes in brooks, like what projected for the Olarias area. The aim oh this work, was to appraise and to monitor the quality oh water this brook, since the first mark the open sky until the local of possible dike, behind the determination the ions Cl-, PO43-, K+, NO3-, NH4+ and yet dissolved oxygen (DO), biochemical oxygen demand (BOD), consumed oxygen (CO), total and fecal coliforms. The analysis results, show that the brook contamination to domestic drain there is found mainly in the first levy mark; showing to be derived from downtown and that happen a gradual recovery of the brook, what indicate the addiction oh drain over it´s curse is less intense, but, his water arrives into the dike area, in similar conditions there is some that is founded in many lakes, whose water are eutrophizades.Em Ponta Grossa-PR, na tentativa de revitalização de determinados espaços, iniciou-se a construção de parques, onde arroios foram ou serão represados para a formação de lagos, com o projetado para a região de Olarias. O objetivo deste trabalho, foi de avaliar e monitorar a qualidade da água do arroio de Olarias, desde o primeiro ponto em que está exposto, isto é, próximo a região central da cidade, até o local da possível represa, através da determinação dos íons Cl-, PO43-, K+, NO3-, NH4+, e ainda oxigênio dissolvido (OD), demanda bioquímica de oxigênio (DBO), oxigênio consumido (OC), coliformes fecais e totais. Os resultados das análises demonstraram, que a contaminação do arroio por esgoto doméstico é mais intenso no primeiro ponto de coleta, e que ocorre uma recuperação gradativa a medida em que ele se desloca em direção a periferia, mas, suas águas, chegam na região da represa, em condições semelhantes a aquelas encontradas em muitos lagos que estão eutrofizados
