(Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia, 2013-06-01) Silva, Luciana C. C. B.; Oliveira, Ana B.; Silva, Danilo C.; Paschoarelli, Luis Carlos [UNESP]; Coury, Helenice J. C. G.; Universidade Federal de São Carlos (UFSCar); Universidade Estadual Paulista (Unesp)
CONTEXTUALIZAÇÃO:O manuseio de materiais está ainda presente nos setores industriais e é associado a lesões na coluna lombar e membros superiores. A inserção de alças em caixas industriais é uma forma de reduzir os riscos relacionados à tarefa, porém a posição e a angulação das alças, que são fatores importantes para o conforto e segurança durante o manuseio, são ainda pouco investigadas objetivamente.OBJETIVOS:Comparar o manuseio de uma caixa comercial e de protótipos com alças e avaliar seus efeitos na postura de membros superiores, atividade elétrica muscular e percepção de agradabilidade em diferentes empunhaduras durante manuseio entre diferentes alturas.MÉTODO:Trinta e sete voluntários saudáveis avaliaram as alças dos protótipos que possibilitavam mudança nas posições (superior e inferior) e angulações (0°, 15° e 30º). Os movimentos dos punhos, cotovelos e ombros foram avaliados por meio da eletrogoniometria e inclinometria. A atividade elétrica muscular dos extensores do punho, bíceps braquial e porção superior do trapézio foi avaliada por um eletromiógrafo portátil. Os registros de movimento e atividade elétrica muscular foram sincronizados. Aspectos subjetivos de agradabilidade foram avaliados por meio de uma escala visual analógica.RESULTADOS E CONCLUSÕES:Os protótipos com alças inclinadas em 30° apresentaram as melhores avaliações de agradabilidade, posturas mais neutras de punho, menores níveis de atividade eletromiográfica do trapézio superior e menores ângulos de elevação dos braços. Os diferentes métodos de medida se mostraram complementares para a avaliação dos membros superiores durante as tarefas de manuseio.

Accessibility and usability of health care equipment for obese patients: A case study in a Brazilian public hospital
(2008-12-01) Do Carmo Lucio, Cristina; Paschoarelli, Luis Carlos [UNESP]; Razza, Bruno Montanari; State University
Obesity is a chronic illness that has been considerably discussed because of its alarming increase. Obese individuals, besides the risk of developing several health and psychosocial problems, have restricted access many products, especially due to problems of size and resistance to weight. Medical and hospital equipment deserves special attention because it demands greater efficiency in promoting patient rehabilitation. This study aimed to analyze if the equipment available in a Brazilian public hospital was satisfactory for obese patients. The research procedure consisted of interviews with professionals and patients, systematic observation of the environment of the study, and metric and descriptive analysis of the equipment. The results indicated that most of the equipment served the majority of the obese patients, even though the equipment was in a bad state of repair. Other products, however, would require immediate intervention to help obese patients.

This paper reports a preliminary study evaluating accessibility and usability of a Brazilian government website - the national digital catalogue of assistive technology (CNPTA). Although since 2004 e-government information should be broadly accessible, several studies indicate that web accessibility has not been accomplished in many government websites. This study is part of a research project that analyses whether this negative outcome replicates on government websites intended for people with disabilities. The website was assessed by automated testing and the results were compared to the outcomes from user testing. The paper discusses the findings compared with past studies and not only proposes specific aspects to enhance the website, but also it outlines several points to be considered in the next steps of the research project, as well as in other research that considers web accessibility and usability for blind people.
Ações de relações públicas aplicadas a projetos de extenção: análise das exposições do laboratório de design solidário
(2011) Mengatti, Lara Bichiato [UNESP]; Goya, Cláudio Roberto y [UNESP]; Silva, Marcelo Formigoni da [UNESP]; Universidade Estadual Paulista (Unesp)
Introdução: O Laboratório de Design Solidário (Labsol) é um projeto de extensão criado em 2007 que tem como objetivo aperfeiçoar e revitalizar objetos artesanais e arranjos produtivos locais, baseando suas atividades no tripé conceitual: ecodesign, sustentabilidade e economia solidária. O LabSol visita grupos de artesãos, analisa seus produtos, métodos de produção e matérias primas e a partir daí, cria-se projetos e protótipos. O Laboratório conta com a atuação de alunos de Relações Públicas desde 2009 e estes têm como função promover ações de/para aprimoramento da comunicação interna e externa, além da parte burocrática e análise de propostas e projetos. No ano de 2011, ocorreram quatro exposições de produtos feitos pelo LabSol. Em cada uma destas exposições, o papel do profissional de RP foi fundamental, pois avaliou os convites, verificou a abrangência de cada público, a relação entre o projeto e os eventos, e tornou possível a sua efetiva realização. Objetivos: O estudo tem como objetivo analisar a validade e o alcance das exposições do Labsol no primeiro semestre de 2011. As exposições ocorreram no evento “Ecorreto” em 07 e 08 de maio; no Festival da Rádio UNESP em 26 de maio; no projeto “Perspectiva” – projeto de extensão da UNESP – em 01 de junho; e na XII Semana do Meio Ambiente de Bauru no Horto Florestal da cidade em 05 de junho. Métodos: As exposições aconteceram por meio de convite dos organizadores dos eventos e se deram através da exibição dos produtos, criados para os grupos de artesões, em pedestais individuais ou em mesas com produtos e cartazes explicativos. A análise será baseada no número de expectadores de cada evento e no interesse do público em relação ao projeto e aos produtos. Resultados: O público de interação em cada evento variou em numero de expectadores. O Festival da Rádio UNESP, contou com uma média de mil e duzentos; a Semana Integrada do Meio Ambiente, cento e cinqüenta; o “Ecorreto”, quinhentos expectadores (durante a exposição e através do site, onde estão fotos e informações sobre o evento); e o Projeto Perspectiva, realizado na cantina da Faculdade de Engenharia da Unesp, não foi mensurado, porém, alcança principalmente os alunos de período vespertino e noturno dos quatro cursos desta faculdade por ser espaço de fluxo constante de alunos. Cada uma destas exposições foi acompanhada pelos RPs. Durante as exposições, diversas pessoas se interessaram pelo trabalho e, conseqüentemente, perguntaram sobre o Laboratório, demonstrando grande interesse. Acredita-se que por meio destes interessados, a informação sobre o trabalho é multiplicada e, portanto, o conhecimento sobre o projeto alcança maior amplitude. Divulgando não apenas o projeto, mas principalmente o tripé conceitual sobre o qual se apoia.

Advances in drug design based on the amino acid approach: Taurine analogues for the treatment of CNS diseases
(2012-10-23) Chung, Man Chin [UNESP]; Malatesta, Pedro [UNESP]; Bosquesi, Priscila Longhin [UNESP]; Yamasaki, Paulo Renato [UNESP]; dos Santos, Jean Leandro [UNESP]; Vizioli, Ednir Oliveira [UNESP]; Universidade Estadual Paulista (Unesp)
Amino acids are well known to be an important class of compounds for the maintenance of body homeostasis and their deficit, even for the polar neuroactive aminoacids, can be controlled by supplementation. However, for the amino acid taurine (2-aminoethanesulfonic acid) this is not true. Due its special physicochemical properties, taurine is unable to cross the blood-brain barrier. In addition of injured taurine transport systems under pathological conditions, CNS supplementation of taurine is almost null. Taurine is a potent antioxidant and anti-inflammatory semi-essential amino acid extensively involved in neurological activities, acting as neurotrophic factor, binding to GABA A/glycine receptors and blocking the excitotoxicity glutamate-induced pathway leading to be a neuroprotective effect and neuromodulation. Taurine deficits have been implicated in several CNS diseases, such as Alzheimer's, Parkinson's, epilepsy and in the damage of retinal neurons. This review describes the CNS physiological functions of taurine and the development of new derivatives based on its structure useful in CNS disease treatment.&; 2012 by the authors; licensee MDPI, Basel, Switzerland.
Aesthetic and symbolic aspects versus usability: Evaluation of daily use product - lemon squeezer
(2012-01-01) Lanutti, Jamille Noretza de Lima [UNESP]; Campos, Lívia Flávia de Albuquerque [UNESP]; Pereira, Douglas Daniel [UNESP]; de Mattos, Liara Mucio [UNESP]; Inokuti, Elen Sayuri [UNESP]; Paschoarelli, Luis Carlos [UNESP]; Universidade Estadual Paulista (UNESP)
Usability has been characterized as a requirement in the development of product design. Besides the physical aspects, the subjects’ perception and their relationship with objects of daily use have been the focus of research in usability. In this sense, the rejection of a product by the user is not necessarily related to being complex or inefficient, but may be associated with factors and aesthetic significance. The objective of this study was to do a perceptual evaluation with objects of daily use, seeking to identify the relationship between product usage factors and factors related to the aesthetic and symbolic values that can be assigned to it. The procedures were based on ethical recommendations. Twelve subjects participated (average age 20,62, s.d. 1,66), that evaluated six different models of lemon manual through Semantic Differential Test composed of ten descriptors related to subjective aspects of the product (modern/classic, beautiful/ugly, common/unusual, essential/dispensable, elegant/inelegant, repulsive/attractive, funny/serious, known/unknown, rational/emotional, humble/sophisticated). The results were analyzed statistically using the nonparametric Wilcoxon test. This analysis demonstrated higher sensitivity (p≤ 0,05) to the descriptors related to subjective aspects of the product (51,33% of cases) when compared to the descriptors of product use (20,66% of cases). However, significant differences (p ≤ 0.05) with these product use descriptors indicate that the shape and morphological structure of the products influence their perceived usability. As an example, two presses with completely opposite morphological characteristics showed significant results (p ≤ 0,05) opposites in all analyzed using descriptors. Thus, the results demonstrate that the Semantic Differential Test for descriptors related to the use of the product allows a significant perceptual assessment and other tests may contribute to the usability of product/system.

(2020-01-01) dos Santos, Aline Darc Piculo [UNESP]; Ferrari, Ana Lya Moya [UNESP]; Medola, Fausto Orsi [UNESP]; Sandnes, Frode Eika; Universidade Estadual Paulista (Unesp); Oslo Metropolitan University; Kristiania University College
Purpose: The aim of this study was to identify factors that influence the perceived stigma of two assistive devices for visual impairment, namely the white cane and smart glasses. Method: Face-to-face semi-structured interviews with eight European students were conducted to probe their experiences and knowledge related to disability, assistive technology, visual impairment, as well as handheld and wearable devices. Results: Close relationships with disabled people seems to have a positive influence on participants perceptions about stigma, disability, and assistive technology. Academic background seems to not have any influence. The aesthetics of assistive devices was observed as an important factor that influences the adoption or abandonment of the device. Conclusion: Device without negative symbolism but with modern aesthetics (smart glasses) were positively accepted by the participants than the device with traditional aesthetics and symbolisms of visual impairment (white cane). Designers should, therefore, consider aesthetics in addition to functionality in order to avoid the perceived stigma, thereby reducing the chances of device abandonment.IMPLICATIONS FOR REHABILITATION Understanding the factors that influence the perceived stigma associated with assistive technology can help designers and developers to reduce assistive technology abandonment and perceived stigma. Designers need to consider both functionality and aesthetics. While functionality is crucial for the users’ adaptation, aesthetics is important for the users’ positive perceptions.
Affective Perception of Disposable Razors: A Kansei Engineering Approach
(2015-01-01) Razza, Bruno; Paschoarelli, Luis Carlos [UNESP]; Universidade Estadual de Maringá (UEM); Universidade Estadual Paulista (Unesp)
In recent decades, the market of consumer products has changed from the production-oriented point of view to a more market-focused, i.e. aiming to attend consumers’ expectations. Today, consumers turn their attention not only to the logical and rational aspects of the product, but increasingly symbolic and emotional factors have gained an important role in buying decision. Some methods have already been used to design emotional meaning in the products, such as the Kansei Engineering with reported results in literature. This study had as a goal to investigate affective aspects of disposable razors perceived by the users and how they relate to product features using Kansei Engineering. Thus, 40 disposable razors commonly found in the international market were evaluated in a virtual system through a variety of pictures (photographic representation) of the products. In order to identify the most relevant product features Morphological Analysis was performed. To evaluate the disposable razors, 321 male adults volunteered in this study. Semantic differential with 17 pairs of bipolar adjectives were employed to construct the semantic space in Kansei Engineering. The results showed no high correlation in the sample. Moderate correlations, however were found in 12 pairs of bipolar adjectives with 13 product features. Thus, it can be assumed that affective responses can be mildly related to product feature, considering limitation of statistic treatment.

(2018-12-31) Iamaguti, Mariana [UNESP]; Gadotti, Marcella; Henriques, Fernanda [UNESP]; Trigueiros, Paula; Universidade Estadual Paulista (Unesp); University of Alberta; University of Minho
This article is the result of initial tests and studies about two systems for chromatic representation. It introduces and discusses the use and importance of two graphic codes created in Portugal as well as their graphic application on information and communication systems in an inclusive manner for individuals with different chromatic perceptions and needs. Designed mainly for people with colour blindness and visual impairment, ColorADD and Feelipa Color Code are alternatives for colour representation via graphic and tactile mediums. From pilot tests, the application, usage and impact of these systems on society and education have been investigated via field research and interviews with their creators, developers and users.
Antropometria da mão humana: influência do gênero no design ergonômico de instrumentos manuais
(2010) Paschoarelli, Luis Carlos [UNESP]; Menin, Mariana [UNESP]; Silva, Danilo Corrêa [UNESP]; Campos, Lívia Flávia de Albuquerque [UNESP]; Silva, José Plácido da [UNESP]; Universidade Estadual Paulista (Unesp)
The wrong sizing of handle instruments can generate ergonomic problems. To know the anthropometry of the hands is indispensable for a correct sizing, especially how much the gender influences in this aspect. The objective of this study was quantitatively to evaluate the influence of the sort in the anthropometry of the hand human being. The results indicate that the differences are significant and that this factor must be considered in design of manual instruments.

(2014) Menin, Mariana [UNESP]; Silva, José Carlos Plácido da [UNESP]; Silva, Danilo Corrêa [UNESP]; Paschoarelli, Luis [UNESP]; Universidade Estadual Paulista (Unesp)
The study of prehistoric artifacts may contribute to understand the development of these artifacts, and also of ergonomics. This study aims to investigate and identify the types of grips of two Brazilian stone tools (scraper / piercer and a slug) approximately 5000 years old through the use of gloves with sensors and contact maps of the hand palm, exploring the best method for research of ergonomics in prehistory. Hence it can contribute to the discussion of a part of the ergonomics’ history that remains underexplored.
Aplicação preliminar do método QRAM para avaliação de riscos para segurança ocupacional na construção civil
(Associação Brasileira de Engenharia de Produção, 2013-06-01) Pinto, Abel; Nunes, Isabel; Ribeiro, Rita; Paschoarelli, Luis Carlos [UNESP]; UNL; UNINOVA; Universidade Estadual Paulista (Unesp)
A segurança ocupacional é imprescindível na indústria da construção civil e a análise e avaliação de riscos para a segurança ocupacional (AARSO) é o primeiro e fundamental passo para alcançá-la, baseado na definição e implementação de programas de prevenção. A AARSO é um processo complexo, que implica a consideração e análise de muitos parâmetros quantitativos e/ou qualitativos que são difíceis de quantificar. As metodologias AARSO utilizadas na indústria da construção civil são baseadas em informação sujeita a incerteza (sendo tratada por técnicas probabilísticas e/ou estatísticas), difusa, imprecisa e/ou incompleta. Isso implica algumas limitações, como, por exemplo, obrigar os analistas a estimar parâmetros ou efetuar comparações com outros canteiros de obras (o que afasta do sistema real em estudo). O objetivo inicial deste estudo foi efetuar a pré-validação de um método AARSO, o QRAM, em duas cidades brasileiras, de médio e grande porte.
