This work presents an analysis of the method of intervention used in the craft of design by SEBRAE in Rio Grande do Norte under the viewpoint of the actors involved, especially the craftsmen and design consultants. The research methodology used was based on the ergonomic work analysis - AET, applying observational techniques and interactive. Data tabulated from the matrix to include comments were analyzed in order to allow the generation of qualitative and quantitative information. The results of this research allow us to affirm that for the process of innovation through the design of intervention are satisfactory for all involved, it is necessary that the bonds of interaction are established and the joint actions in the innovation process to bear fruit in favor sustainability of artisan groups

The necessity of adapting the standardized fan models to conditions of higher temperature has emerged due to the growth of concerning referring to the consequences of the gas expelling after the Mont Blanc tunnel accident in Italy and France, where even though, with 100 fans in operation, 41 people died. However, since then, the defied solutions have pointed to aerodynamic disadvantages or have seemed nonappropriate in these conditions. The objective of this work is to present an alternative to the market standard fans considering a new technology in constructing blades. This new technology introduces the use of the stainless steel AISI 409 due to its good adaptation to temperatures higher than 400°C, particularly exposed to temperatures of gas exhaust from tunnels in fire situation. Furthermore, it presents a very good resistance to corrosion and posterior welding and pressing, due to its alloyed elements. The innovation is centered in the process of a deep drawing of metallic shells and posterior welding, in order to keep the ideal aerodynamic superficies for the fan ideal performance. On the other hand, the finite element method, through the elasto-plastic software COSMOS permitted the verification of the thickness and structural stability of the blade in relation to the aerodynamic efforts established in the project. In addition, it is not advisable the fabrication of blades with variable localized thickness not even, non-uniform ones, due to the verified concentration of tensions and the difficulties observed in the forming. In this way, this study recommends the construction of blades with uniform variations of thickness. © 2007 Springer.

The purpose of this paper is to propose a definition of the term “green/environmental innovation”, based on a systematic literature review. Design/methodology/approach– The literature review conducted in this research was based on papers published in ISI Web of Science and Scopus databases. Findings– Environmental innovations are organizational implementations and changes focusing on the environment, with implications for companies’ products, manufacturing processes and marketing, with different degrees of novelty. They can be merely incremental improvements that intensify the performance of something that already exists, or radical ones that promote something completely unprecedented, where the main objective is to reduce the company's environmental impacts. In addition, environmental innovation has a bilateral relationship with the level of proactive environmental management adopted by companies. Increasing of environmental innovation tends to come up against many barriers.

After crossing several generations and countries, broader functions are being incorporated to origami than simply making art objects: the fold initiates a series of new buildings within the design and creation. Under the new repre- sentations and performances that the art of paper folding keeps, this article aims to investigate how the origami is configured nowadays and how it behaves while contemporary language applied to projective processes of diverse natures. To better understand the actual origami, relations are used inside branch of math, conceptual and projectual. Relating theorists, artists, designers, etc., can point out the relevance of each of these areas in the configuration of cientific and projectual origami. The modularity, the collective, the conscious build, the contemporary and the inno- vation are relationships intrinsic to the praxis projectual that shape a landscape adjacent and subordinate to the main structure governing. It bets on the essence of origami as a tangible functionality for creative thinking.

Purpose – The purpose of this paper is to show results from the relationship between green/environmental training and the development of three projects of low-carbon eco-innovations in top Brazilian companies. Design/methodology/approach – This study includes three organizational projects for low-carbon eco-innovations in products (A, B and C) with the objective of reducing their impact on GHG emissions, the so-called low-carbon products. Data were collected from several sources of evidence, including in-depth interviews, document analyses and direct observations. Findings – The authors verified that the environmental training interface for mitigating climate change is relevant for the systematic development of low-carbon products in most of the cases studied. Originality/value – Low-carbon eco-innovations are a trend in the corporate world; however, there is not enough literature and practical evidence on this subject. Thus, this paper adds new evidence to the literature.

This work discusses the theories of TRIZ and Design Thinking, as well as the association of the two theories by a tool for the application of TRIZ in a Design Thinking environment. This work proposes the association of the theories by an easy and systematic method constituted by a step by step process. The objective of this work is to create a method that facilitates the application of the two innovation theories helping the inventors to develop new products without the necessity of being creative people. By the end of the work is shown the research case accomplished as an empirical analysis of this tool that can be a fast and efficient method to solve inventive problems focused in the expectations and necessities of the clients

The ALRED construction is a lightweight strategy for constructing message authentication algorithms from an underlying iterated block cipher. Even though this construction's original analyses show that it is secure against some attacks, the absence of formal security proofs in a strong security model still brings uncertainty on its robustness. In this paper, aiming to give a better understanding of the security level provided by different authentication algorithms based on this design strategy, we formally analyze two ALRED variants-the MARVIN message authentication code and the LETTERSOUP authenticated-encryption scheme,-bounding their security as a function of the attacker's resources and of the underlying cipher's characteristics.
