Material Properties and Application of Biomechanical Principles Provide Significant Motion Control Performance in Experimental Ankle Foot Orthosis-Footwear Combination

Hovorka, Christopher F., Kogler, Géza F., Chang, Young H., Gregor, Robert 01 February 2021 (has links)
Background: This study, the first of its kind, originated with the need for a brace (an ankle foot orthosis), to constrain ankle plantarflexion and dorsiflexion within a motion threshold of <5°. A conventional thermoplastic, solid brace failed during a quasi-static loading study, informing the investigation and development of an experimental carbon composite brace, maximizing stiffness and proximity of shank and foot cylindrical shells to provide the required degree of control. Methods: Two experiments were conducted: a quasi-static loading study, using cadaveric limbs (n = 2), and a gait study with healthy subjects (n = 14). Conditions tested were STOP, FREE, and CONTROL. Data for all studies were collected using six motion-capture cameras (Vicon, Oxford, UK; 120 Hz) tracking bone-anchored markers (cadaveric limbs) and skin-anchored markers (subjects). In the quasi-static loading study, loading conditions were congruent with the gait study. Study 1 involved a quasi-static loading analysis using cadaveric limbs, compared motion data from a conventional thermoplastic solid brace and the experimental brace. Study 2 involved quantifying ankle plantarflexion and dorsiflexion in subjects during treadmill walking, in brace STOP, FREE, and CONTROL conditions. Findings: The experimental brace in STOP condition consistently constrained ankle plantarflexion and dorsiflexion below the motion threshold of <5°, across all studies. Interpretation: Collectively, these findings demonstrate (1) that a conventional thermoplastic, solid brace was ineffective for clinical applications that required significant motion control, and (2) that ankle motion control is most effective when considered as a relationship between the brace, the ankle-foot complex, and the external forces that affect them both.

Footwear cues influencing perceived quality and consumer satisfaction amongst Generation Y consumers at River Square Mall, Vereeniging

Mbambonduna, Thobeka 04 1900 (has links)
M. Tech. (Department of Fashion, Faculty of Human Sciences), Vaal University of Technology. / The focus of this dissertation is to examine the relationship between footwear cues, perceived quality and consumer satisfaction amongst Generation Y at River Square mall in Vereeniging. This research considers the effects of these cues as important arrays of quality indicators that consumers utilise in their evaluation process when selecting products. This knowledge is important to managers in the footwear industry. The lack of these considerations may lead to the manufacturing of fashion footwear that may not meet the consumers expectation regarding quality of the product and hence their satisfaction or possibly dissatisfaction. Footwear is alleged to be indispensable for the development of fashion apparel. Thus, the study sought to investigate underlying variables that influence footwear for the purpose of identifying ways in which the fashion industry can improve performance and presentation of footwear. A conceptual model was developed, drawing from cue utilization theory (CU) and utility theory (UT). Generation Y consumers at River Square mall in Vereeniging formed the sample of the study. A survey was conducted and research data was collected from 550 consumers. Structural Equation Modelling (SEM) was used to analyse the data via Statistical Package for the Social Sciences (SPSS) 22 and Analysis of Moment Structures (AMOS) 22. The findings indicate that footwear cues have a strong influence on perceived quality and perceived quality has a strong influence on satisfaction amongst Generation Y consumers. This indicates that Generation Y consumers perceive quality of footwear through extrinsic and intrinsic cues hence their satisfaction. Consequently fashion footwear business should regard effective cues when trading footwear.

Dopad užívání různých typů bežecké obuvi na stabilitu a vznik zranění u vytrvalostních běžců / Influence of defferent kinds of running shoes on stability and risk of injury in long - distance runners

Krchová, Zuzana January 2014 (has links)
The main problems concerning birth of running injuries is their unclear ethiopathogenesis and high frequency. Injuries are often lined with forces affected on tread-down which have to be defused by running shoes. There are also opinions that currently used footwear can cause injuries on the contrary. This work explores impact of particular types of running shoes for influencing of stability. Methods: There are compared two groups of runners: minimalists and classic runners. Their stability is examined with help of posturography in three versions: barefoot, classic and minimalistic footwear. Thereafter there is analyzed relation among stability, used footwear, training usage and frequency of injuries. Results: Minimalists and classic runners have the same stability while they are barefoot. Usage of footwear does not cause significant deterioration of stability in any of groups. Nevertheless most of runners subjectively evaluate the variant of testing barefoot as the simplest. There is more frequent occurence of flat foot among classic runners in comparison with minimalists. Flat foot increases risk of formation injuries, on the contrary, regular compensation motion activity decreases this risk.

Almeida, Marina Stefani de 26 September 2008 (has links)
The aim of this study is to analyze how outsourcing manifests in the Francas footwear industry, interior of São Paulo, and to bring up the consequences of this process for the labor market in this area and for its workers. The research shows that outsourcing has increased segmentation of the labor market in this sector, which was present before, and has fragmented the footwear working class into innumerous atypical forms of work situations, among these the self-employment, domiciliary work, the providers micro-firms and the formal and informal outsourced workers. The outsourcing in Franca calls into question the predominance of the classic industrial work and promotes the dismantling of the workers rights through the flexibilization of the workforce management. The study focuses not only on the technical aspects of outsourcing but, mainly on the experience and subjectivity of the productive actors that experience this process, mentioning the everyday work and the labor relations established in these small productive units. The work uses semi structured interviews, as well as quantitative data about the sector, when they are available. / The aim of this study is to analyze how outsourcing manifests in the Francas footwear industry, interior of São Paulo, and to bring up the consequences of this process for the labor market in this area and for its workers.

Uma análise nos principais aspectos da construção calçadista para o desenvolvimento de um solado-protótipo feito a partir de fibra de coco / An analysis in the main aspects of the footwear construction for development of a prototype soloed made from coconut fibers.

Costa, Célia Regina da 02 April 2013 (has links)
Os calçados são essenciais na vida humana, eles possuem a função primordial de proteger os pés e interagem constantemente com o indivíduo. Além do aspecto funcional, se exige qualidade, conforto e estética em sua confecção. Os fatores antropométricos e biomecânicos contribuem nessa interface ao oferecer parâmetros científicos na sua forma ergonômica. Confeccionar um calçado que garanta a saúde para os pés necessita conhecer os fatores que estão direta ou indiretamente relacionados à sua história, ao processo de produção, a matéria-prima entre outros itens relacionados ao calçado, assim com um embasamento científico pode dar um melhor suporte ao processo de desenvolvimento do produto. Neste contexto, a dissertação teve por objetivo organizar estes conceitos de maneira que forneça informações essenciais para a construção de um calçado confortável, pois há uma dificuldade em encontrar uma gama de conhecimentos reunidos sobre calçados para o desenvolvimento de novos projetos. Neste sentido, o estudo investigou também as características da fibra de coco verde, dos frutos descartados na cidade de Francisco Morato - São Paulo, para verificar a viabilidade de aplicação dessas fibras na construção de partes do calçado. Para a realização deste trabalho foi fundamentado uma revisão teórica que apontou a evolução do calçado na história da humanidade, os fatores indispensáveis para oferecer o conforto, a análise do pé humano, conhecimento sobre a matéria-prima e algumas possibilidades de agregarem a fibra natural de coco verde para a fabricação de um protótipo para solado feito da fibra coco. A metodologia utilizada refere-se aos aspectos teóricos numa abordagem de conhecimentos para a confecção calçadista e, que possam ser empregados na etapa da produção do protótipo. Foi feita uma maceração biológica nas fibras e realizados testes de tração e microscopia óptica. As fibras foram extraídas do coco, analisadas em testes laboratoriais e posteriormente agregadas a uma resina (PVAc Poliacetato de Vinila) para formar o protótipo. Os resultados mostraram que as fibras de coco verde possuem potencial em relação a outras fibras naturais estudadas em literaturas, para serem aplicadas como reforços na construção de partes do calçado. Possuem a rigidez necessária aos materiais usados na fabricação do sapato e, uma proteção natural graças à presença de lignina. Porém, há necessidade de que as informações da cadeia produtiva sejam mais acessíveis e amplas a nível científico e, possibilitem a criação de alternativas mais eficazes e na melhoria das técnicas já existentes no mercado. Há uma grande possibilidade do emprego das fibras naturais em substituição das fibras sintéticas para serem empregadas na fabricação de partes dos calçados como, por exemplo, nos solados e palmilhas. / Shoes are essential mode of human life; they have the primary function of protecting the feet and constantly interact with the individual. Besides the functional aspect, if demands quality, comfort and aesthetics in its making. The anthropometric and biomechanical factors contribute to this interface and provide scientific parameters for its ergonomic design. Manufacturing a shoe that ensures the health of the human foot aims to know the factors that are directly or indirectly related to its history, production process, raw materials and other factors related to shoes, so with a scientific background can better support the process of product development. In this context, the dissertation aimed to organize these concepts in a way that provides essential information for the construction of comfortable shoes and can influence new ideas to use in the footwear sector, since there is a difficulty in finding a range of knowledge gathered over shoes, which are important for the development of new projects. In this sense, the study also investigated the characteristics of green coconut fiber, fruit discarded in the town of Francisco Morato - São Paulo, to verify the feasibility of these fibers in the construction of parts of footwear. For this work was based showed that a theoretical evolution of footwear in the history of mankind, the factors necessary to provide comfort, a study of foot, knowledge of the raw materials and some possibilities of aggregating the natural fiber coconut for manufacturing a prototype for soles made of coconut fiber. The methodology used refers to the theoretical approach knowledge for making footwear and which may be used in the production step of the prototype. We conducted a biological maceration into the fibers and performed tensile testing and optical microscopy. The fibers were extracted from coconut analyzed in laboratory tests and then aggregated to a resin (PVAc - Vinyl polyacetate) to form the prototype. The results showed that coconut fibers have potential in relation to other natural fibers studied in literatures, for use as reinforcements in building parts of the footwear. Have the necessary rigidity to the materials used in manufacturing the shoe, and a natural protection due to the presence of lignin. However, there is need for the information of the production chain are more accessible and wide-ranging scientific level and thus allow the creation of more effective alternatives and that the techniques could be improved. There is a great possibility of using natural fibers in place from synthetic for use in footwear, for instance, in the soloed and shoe insole.

Proposta de um modelo de gestão de resíduos industriais para o setor calçadista de Franca-SP com vistas à Política Nacional de Resíduos Sólidos / Proposal of a model of industrial waste management to the footwear industry in Franca-SP based on the Nacional Solid Waste Policy

Breda, Francisco de Assis 20 April 2016 (has links)
Criado inicialmente com a função básica de proteção aos pés, o calçado tornou-se um objeto de desejo e um acessório essencial de moda. Entre 1950 a 2015, estima-se que a produção mundial passe de 2,5 bilhões de pares produzidos para 25 bilhões de pares por ano, crescimento bem maior do que a população mundial. O couro, principal matéria-prima para a confecção de calçados, caracteriza-se por gerar grandes quantidades de resíduos ao longo de toda a cadeia produtiva. Especificamente na indústria coureiro-calçadista, o problema concentra-se nos elevados volumes de resíduos gerados na atividade produtiva, podendo causar desperdícios e grandes volumes de resíduos a serem descartados, envolvendo, principalmente, questões financeiras e ambientais. Países como Alemanha e Estados Unidos possuem legislação específica sobre a gestão de resíduos desde os anos 1970. No Brasil, depois de mais de 20 anos de tramitação no Congresso Nacional, em 2010, foi instituída a Política Nacional de Resíduos Sólidos, que reúne princípios, objetivos, instrumentos, diretrizes e metas, que deverão ser adotados pelos governos nas esferas federal, estadual e municipal, bem como pelas empresas com vistas à gestão integrada e ao gerenciamento ambientalmente adequado dos resíduos sólidos. Dessa forma, o objetivo desta tese foi desenvolver um modelo de gestão de resíduos industriais para o setor calçadista de Franca-SP com vistas à Política Nacional de Resíduos Sólidos. O desenvolvimento do modelo teve como ponto de partida um estudo bibliográfico sobre o assunto e, na sequência, por intermédio de uma pesquisa aplicada, conseguiu-se, em um primeiro momento, analisar a situação atual para compreender o modelo de gestão de resíduos vigente e realizar uma pesquisa de diagnóstico dos resíduos industriais do setor. Tal pesquisa possibilitou verificar que atualmente, esses resíduos, são enviados em sua totalidade para aterros sanitários, possibilitou também sua quantificação e cálculos dos custos envolvidos para transporte e destinação. Na sequência, realizaram-se estudos sobre a viabilidade técnica e financeira para tratamento térmico desses resíduos e a busca de benchmark no setor. O estudo também proporcionou uma contribuição de caráter mais prático e/ou gerencial ao recomendar diretrizes para a elaboração de um plano de gestão integrada de resíduos industriais para o setor, e uma proposta de gestão compartilhada dos resíduos industriais entre a entidade de classe e as indústrias calçadistas, com vistas à eliminação de envio desses resíduos para aterros. Dessa forma, contribuiu também para a elaboração do Plano Municipal de Gestão Integrada de Resíduos Sólidos do município em questão. Nesse sentido, após as análises e desdobramentos das etapas anteriores, foi possível propor um modelo de gestão de resíduos industriais, bem como demonstrar sua viabilidade técnica e financeira. Tal modelo foi denominado \"Modelo de Equiparação de Custos com Eficiência Ambiental\". / Initially created with the basic function of feet protection, the footwear became an object of desire and an essential fashion accessory. Between 1950 and 2015, it is estimated that the worldwide production expanded from 2,5 billions to 25 billions of pairs a year, an increase much higher than the worldwide population. The leather, the main feedstock for the footwear manufacture, is characterized by generating large amounts of waste throughout the production chain. Especially in the leather-footwear industry, the major problem is concentrated in the big volumes of waste generated in the productive activity, which can lead to wastage and big volumes of waste to be discarded, involving several financial and environmental issues. Countries such as Germany and United States of America have specific legislation concerning the waste management since 1970. In Brazil, after more than 20 years being analyzed by the National Congress, in 2010, the National Solid Waste Policy was established, gathering principles, instruments, guidelines and goals, which must be adopted by the federal, state and municipal levels of government, as well as by the companies, following the integrated and adequate environmental management of solid waste. Therefore, the goal of this thesis was to develop a model of industrial waste management to the footwear industry in Franca-SP, according to the National Solid Waste Policy. The starting point of the development of this model was a bibliographical study about the subject, followed by an applied research. In a first moment, it was possible to analyze the current situation to comprehend the current model of waste management and to perform a diagnostic research of the sector. This research enabled us to verify that currently, these wastes are entirely sent to landfills, and also allowed quantification and calculation of the costs involved for transport and disposal. Afterwards, studies were performed to investigate the technical and financial feasibility of the thermal treatment of this waste and to search the benchmarking of the sector. The study also provided a more practical contribution as it recommended a guideline to elaborate a plan of integrated management of industrial waste to the footwear sector and as it proposed a model to be shared between the industries and trade unions, with the aim of eliminating the landfills as a destination of this waste. Therefore, this thesis also contributed to elaborate the Municipal Plan of Integrated Management of Solid Waste in the aforementioned city. Accordingly, after the analysis and consequences of previous steps, it was possible to propose a model of industrial waste management, as well as to demonstrate its technical and financial feasibility. This model was nominated \"Model of Costs Equalisation with Environmental Eficiency\".

No. of bitstreams: 1 André Daudt dos Reisl_.pdf: 892854 bytes, checksum: bfdcabf865063fa082e791fdad02b209 (MD5) Previous issue date: 2018-04-25 / UNISINOS - Universidade do Vale do Rio dos Sinos / Este trabalho teve como objeto de pesquisa analisar os fatores que influenciam a internacionalização de operações de e-commerce do setor calçadista brasileiro para a América do Sul, mais especificamente para a Argentina, Chile e Colômbia. Este estudo também buscou identificar as principais barreiras para a internacionalização destas empresas, níveis de controle exigido por elas e a proposição do modo de entrada mais adequado. Para alcançar tais resultados, foi realizada uma pesquisa de campo qualitativa que obteve, durante o processo de coleta de dados, entrevistas com profissionais especialistas em comércio eletrônico para a América do Sul e executivos de indústrias calçadistas que trabalham com marca própria, possuem operações de e-commerce no Brasil, já exportam para os mercados em questão nesta monografia e que possuem interesse em internacionalizar seus negócios digitais. Os resultados encontrados foram de que os fatores externos como infraestrutura de logística e telecomunicações, serviços de apoio, formas de pagamento eletrônica e propensão do consumidor são similares aos padrões do mercado brasileiro. Entretanto, no âmbito de legislações locais há muita divergência, transformando este fator num entrave operacional. Aliado a isso, as empresas brasileiras exigem um nível de controle alto sobre gestão comercial e de marca, fazendo com que o modo de entrada mais adequado nesse cenário seja modos contratuais com controle compartilhado, numa modalidade de franquia ou licenciamento. / The research objective of this monography is to analyze the influence factors of the internationalization of e-commerce operations from the Brazilian footwear industry to South American countries, more specific to Argentina, Chile and Colombia. This study also seek to identify the main barriers for these companies internationalization, which are the control required by them and the more suitable entry mode proposal. To achieve these results, it was done a qualitative field research with a data collection composed by interviews with professionals specialized in electronic commerce in South America. Also, executives from the footwear industry, who work with their own branded products, have e-commerce operations in Brazil, are exporters to Argentina, Chile and Colombia and have interest in internationalize their e-commerce to those countries were interviewed. The results findings were that the external factors such as logistics and telecommunication infrastructure, related services, electronic payment options and consumer propensity were similar to the Brazilian standard. However, there were many discrepancies regarding local legislation, making it the main barrier for the internationalization of those companies. In addition, Brazilian companies demand a high-level control under the commercial and brand management, making the more suitable entry mode option the one with share control over the operation, like a licensing mode.

O design de calçados na (re)evolução digital. Proposta de uma metodologia para análise de desempenho de calçados femininos com foco no conforto do usuário, utilizando a modelagem virtual e a impressão 3D / The design of footwear in (digital) evolution. Proposal of a methodology for analyzing the performance of women\'s shoes focused on user comfort, using virtual modeling and 3D printing

Silva, Jose Augusto Marinho 28 June 2016 (has links)
O design de calçados femininos de salto alto frequentemente tem características de projeto com foco no styling ao invés de projeto centrado no usuário, uma vez que a estética prevalece em relação ao conforto. No presente trabalho, desenvolve-­-se uma abordagem metodológica para o projeto de calçados, focado na melhor adaptação aos pés dos usuários, representados pelo universo das mulheres, com a característica do \"sob medida\", visando principalmente o conforto. Como estudo de caso considera-­-se o calçado comercial, feminino e de salto alto. A metodologia consiste na uHlização de simulação virtual para análise do desempenho, podendo prever possíveis falhas antes da produção em escala, principalmente pelos estudos dos fenômenos relacionados com as deformações dos materiais sofridas por cargas aplicadas, ou seja, tensão x deformação. A elaboração do modelo de análise ocorreu pela obtenção de dados de pressão plantar realizados em ensaios de baropodometria, uHlizando palmilhas com sensores que medem as pressões instantâneas durante o passo. Os calçados selecionados foram cedidos por uma marca comercial conhecida e atuante no mercado brasileiro há mais de 30 anos, sendo modelos sociais, Hpo sandálias e scarpins, considerados produtos de luxo. Três alturas de salto foram usadas nas medições, e para o mais alto deles, uHlizou-­-se dois modelos, um de salto fino e outro de salto com base retangular. Essas medições são os dados de entrada para o so-ware de análise pelo método dos elementos finitos. As forças aplicadas em uma palmilha virtual simulam as regiões dos picos de pressão obHdas pela baropodometria, caracterizando a distribuição da pressão plantar. Essas análises podem auxiliar novos projetos de calçados, dando o suporte necessário para a idealização de soluções que proporcionem diminuir os picos de pressão, causando assim menor desconforto e maior adequação do projeto às caracterísHcas fisiológicas de cada usuário pela criação de palmilhas anatômicas e personalizadas, como sugere o resultado das análises. Uma vez que é uHlizada uma metodologia que consiga prever o desempenho de um calçado antes da sua fabricação, são inúmeras as vantagens que podem auxiliar na oHmização e melhoria dos calçados existentes, ao reduzir o tempo de desenvolvimento e os custos envolvidos, além de garanHr a qualidade do produto. Tanto o design de calçados comerciais quanto conceituais analisado pelo método dos elementos finitos pode ser inspirado pelos resultados de desempenho, influenciando as escolhas de soluções que auxiliem na definição do melhor projeto. Ao final do trabalho foi desenvolvido um protóHpo experimental de um calçado feminino de salto alto que reforçou a validação da pesquisa. / The design of women\'s high-heeled shoes often has design features with Focus on styling rather than user-centered design, since steHca prevails in Relation to comfort. In the present work, a methodological approach is developed for the Footwear design, focused on the best adaptation to the feet of the users, represented by the Women\'s universe, with the characteristic of \"tailor-made\", mainly aimed at comfort. As a case study it is considered the commercial footwear, feminine and high heels. The methodology Virtual simulation for performance analysis, and can predict possible Prior to scale production, mainly due to the studies of the phenomena related to With the deformations of the materials undergone by applied loads, that is, tension x deformation. A The model analysis was performed by obtaining plantar pressure data In baropodometry tests, using insoles that measure pressures During the step. The selected footwear was given by a trademark Known and active in the Brazilian market for more than 30 years, being social models, Hpo Sandals and scarpins, considered luxury products. Three heel heights were used in the Measurements, and for the highest of them, two models were tested, one with a Rectangular base. These measurements are the input data for the analysis software by the method Of finite elements. The forces applied in a virtual insole simulate the regions of the peaks Pressure obtained by baropodometry, characterizing the plantar pressure distribution. These analyzes can aid in new shoe designs, giving the necessary support for the Solutions that reduce pressure peaks, thus Discomfort and greater suitability of the design to the physiological characteristics of each user by the Creation of anatomical and customized insoles, as suggested by the analysis results. Once That a methodology is used to predict the performance of a footwear prior to its The advantages that can aid in the improvement and improvement of footwear. Reducing development time and costs involved, as well as product quality. Both the commercial and conceptual footwear design analyzed by the Finite element method can be inspired by the performance results, influencing the The choices of solutions that help in the definition of the best project. At the end of the study, Developed an experimental prototype of a high-heeled women\'s shoe that reinforced the Validation of the research.
