Metodologia kansei no desenvolvimento de novos produtos

Mestrado em Engenharia Mecânica de ProduçãoEste trabalho apresenta a problemática preocupação na conceção, qualidade e desenvolvimento de produtos, objetivando utilizar técnicas de projeto, em particular da metodologia Kansei na compreensão e vasta aplicação do tema. O Kansei detém grande utilidade no apoio aos profissionais de engenharia e design em tomadas de decisões com alto grau de incerteza e complexidade na criação de novos produtos. O estudo realizado propôs uma metodologia, abordando técnicas da Engenharia Kansei em simultâneo com QFD, introduzindo na metodologia ferramentas estratégicas de captação de informações para o enquadramento metodológico. O método utiliza uma pesquisa bibliográfica, livros, artigos científicos e aplicações práticas, procurando entender sucintamente a compreensão dos requisitos que envolvem o conteúdo da metodologia proposta. A metodologia enquadra-se em três fases, identificando e compreendendo as Necessidades dos Clientes, Processamento das informações e Desenvolvimento e Validação do produto na terceira fase. Na análise metodológica observou-se uma dificuldade de interações metodológicas existentes. Os resultados do trabalho possibilita uma aplicação futura no desenvolvimento de produto que represente a intensão da metodologia. Em, conclusão, o Kansei é uma metodologia com forte desenvolvimento e seu estudo é necessário, compreendendo suas técnicas desenvolvidas na melhoria contínua em produtos, contribuindo para ás necessidades do utilizador e auxílio das empresas

Influence of Heavy Metals on the Nitrogen Metabolism in Plants

As an essential element, Nitrogen is needed in large quantities for being an important component of cellular constituents and for plant metabolism, and its deficiency is one of the most common limitations for plant development. The study of the toxic effects of metal in plants involves a complex system of reactions that can be better determined once having a large attention of the different backgrounds of occurence to determinate how to proceed. The objective of this review is to add scientific knowledge, addressing the main functionalities and characteristics of this relation heavy metals – nitrogen metabolism in plant. Increasing industrialization and urbanization had anthropogenic contribution of heavy metals in biosphere and had largest availability in ecosystems. This toxicity in plants varies with plant species, specific metal, concentration, soil composition, as many heavy metals are considered to be essential for plant growth. Were provided data and reviews regarding the effect of heavy metals on nitrogen metabolism of plants and the responses of plants and the cross-talk of heavy metals and various stressors factors. Is clear to understand the relation between metals amount and the benefit or harm caused on plants, determining then, which mechanism should be activated to protect your physiological system

VIOLÊNCIA CONTRA CRIANÇA E ADOLESCENTE: ROMPENDO O SILÊNCIO

Se trata de una investigación descriptiva, exploratoria, de planteo cualitativo, con el objetivo de identificar situaciones de violencia vividas por niños y adolescentes de una escuela pública en la comunidad Santo Amaro, Recife-PE. Participaron 58 niños y adolescentes de enseñanza primaria. Se aplicó un impreso de entrevista con registro de las declaraciones, permi- tiendo la construcción de las siguientes categorías: 1- Situaciones que los niños y adolescentes preferirían no haber vivido; 2- Expectativas y deseos de los niños y adolescentes en relación al futuro. Entre las situaciones que los niños y adolescentes preferirían no haber vivido fueron identificadas: Violencia interna familiar; Situaciones de exclusión; Violencia interper- sonal y muerte; Precocidad en la iniciación sexual y Violencia sexual. Cuanto a las expectativas y deseos de los mismos en relación al futuro se evidenció el deseo de un futuro con cambios, en su barrio con disminución de la violencia, de obtener una titulación profesional que represente una posición social desprovista de la imagen de marginalidad que constituye el cotidiano de la periferia

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial

Background: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. Methods: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. Results: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P <.01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P =.15). Secondary end points did not differ between groups after follow-up. Conclusions: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death. © 2019 The Author
