Study and comparison of physiological response with Harmony® suspension system and suspension with pin

The purpose of this study is a cross-qualitative and quantitative gait analysis in 3 traumatic unilateral amputees using prosthesis with pin suspension compared to the use of prosthesis with a high vacuum suspension, the Harmony® system. In Portugal, there aren’t many studies made in the field of orthotic and prosthetic and knowledge about the number of amputees in the country. The only know is that the major cause of lower limb amputation is diabetes mellitus, being the most affected population the older age groups. The combination of technological developments with daily needs of the amputees is becoming more and more important for they better quality of life. This work was done during the curricular unit “Investigation in Prosthetics and Orthotics” class, in the 4th year of Health Technology School of Lisbon, in Portugal. This study analyzes if the change of suspension in transtibial prosthesis will influence some physiological response in amputees.

O currículo funcional no desenvolvimento da autonomia e da comunicação oral e escrita

Os alunos com necessidades educativas especiais, mais concretamente os alunos que apresentam deficiência mental, com limitações acentuadas no comportamento adaptativo, necessitam um ensino mais individualizado, com uma vertente mais funcional. Os currículos funcionais, planeados de acordo com os contextos de vida atuais e futuros em que cada aluno se insere e se irá inserir, permitem desenvolver competências com significado e úteis para a formação pessoal, social e laboral, possibilitando uma vida adulta com mais qualidade e com mais autonomia. Este estudo incide no desenvolvimento de atividades funcionais para a promoção da autonomia e da comunicação oral e escrita em duas crianças, com 11 anos de idade, com défice cognitivo. Delinearam-se três objetivos para o estudo: i) caraterizar o nível de desenvolvimento e aprendizagem de duas alunas com défice cognitivo, nomeadamente no que respeita à autonomia e ao desenvolvimento da linguagem; ii) desenvolver conteúdos, estratégias e atividades funcionais que facilitem o progressivo aumento da participação das alunas em contextos reais de atividades de vida diária; iii) contribuir para o desenvolvimento de competências de autonomia e comunicação oral e escrita de duas alunas com défice cognitivo. Organizou-se um projeto de intervenção, desenvolvido na lógica da investigação ação. De modo a se elaborar o plano de intervenção, avaliaram-se as competências das alunas ao nível da comunicação oral e escrita, autonomia e funcionalidade, recorrendo à análise documental, a entrevistas às encarregadas de educação e à docente de Educação Especial, à observação direta e à elaboração de diários de aula. O plano de intervenção foi planeado no quadro dos currículos funcionais e centrou-se em atividades de vida diária, selecionadas a partir da análise das necessidades atuais e futuras das alunas. Após a implementação da intervenção, concluiu-se que a aplicação de atividades de um currículo funcional melhorou as competências de autonomia e de comunicação oral e escrita das alunas.- Abstract: Students with special educational needs, more specifically students who have mental disabilities, with significant behavior limits to adapt, need a more individual and functional education. The functional curriculum, planned according to the current and future life contexts in which every student is and will be, allow the development of meaningful skills, useful to their personal education, social life and labour, enabling them with an adulthood life with more quality and more autonomy. This study focuses on the development of functional activities for the promotion of autonomy and of oral and written communication in two children with 11 years old with mental disability. Three goals were outlined for the study: i) to characterize the level of development and learning of two students with cognitive dysfunction, regarding particularly the autonomy and the language development, ii) to develop contents, strategies and functional activities that increase the participation of the students in real daily life activities, iii) to contribute to the development of autonomy and oral and written communication of two students with mental disability. We organized an intervention project, developed in the logic of action research. In order to develop the intervention plan, we evaluated the level of oral and written communication, autonomy and functionality, through document analysis, interviews to the guardians and to the Special Educational teacher, as well as through direct observation and preparation of diaries of lessons. The intervention plan was outlined within the framework of functional curriculum and focused on activities of daily living, selected trough the analysis of current and future needs of the students. After the implementation of the intervention plan, we observed that the application of the activities of a functional curriculum improved the skills of autonomy and oral and written communication of the students

Syntheses, Molecular Structures, Electrochemical Behavior, Theoretical Study, and Antitumor Activities of Organotin(IV) Complexes Containing 1-(4-Chlorophenyl)-1-cyclopentanecarboxylato Ligands

The organotin(IV) compounds [Me2Sn(L)(2)] (1), [Et(2)sn(L)(2)] (2), [(Bu2Sn)-Bu-n(L)(2)] (3), [(n)Oct(2)Sn(L)(2)] (4), [Ph2Sn(L)(2)] (5), and [PhOSnL](6) (6) have been synthesized from the reactions of 1-(4-chlorophenyl)-1-cyclopentanecarboxylic acid (HL) with the corresponding diorganotin(IV) oxide or dichloride. They were characterized by IR and multinuclear NMR spectroscopies, elemental analysis, cyclic voltammetry, and, for 2, 3, 4 and 6, single crystal X-ray diffraction analysis. While 1-5 are mononuclear diorganotin (IV) compounds, the X-ray diffraction of 6 discloses a hexameric drumlike structure with a prismatic Sn6O6 core. All these complexes undergo irreversible reductions and were screened for their in vitro antitumor activities toward HL-60, BGC-823, Bel-7402, and KB human cancer cell lines. Within the mononuclear compounds, the most active ones (3, 5) are easiest to reduce (least cathodic reduction potentials), while the least active ones (1, 4) are the most difficult to reduce. Structural rearrangements (i.e., Sn-O bond cleavages and trans-to-cis isomerization) induced by reduction, which eventually can favor the bioactivity, are disclosed by theoretical/electrochemical studies.

How new online communication tools and the availability of content influence the audiences and the creative process

We live in a changing world. At an impressive speed, every day new technological resources appear. We increasingly use the Internet to obtain and share information, and new online communication tools are emerging. Each of them encompasses new potential and creates new audiences. In recent years, we witnessed the emergence of Facebook, Twitter, YouTube and other media platforms. They have provided us with an even greater interactivity between sender and receiver, as well as generated a new sense of community. At the same time we also see the availability of content like it never happened before. We are increasingly sharing texts, videos, photos, etc. This poster intends to explore the potential of using these new online communication tools in the cultural sphere to create new audiences, to develop of a new kind of community, to provide information as well as different ways of building organizations’ memory. The transience of performing arts is accompanied by the need to counter that transience by means of documentation. This desire to ‘save’ events reaches its expression with the information archive of the different production moments as well as the opportunity to record the event and present it through, for instance, digital platforms. In this poster we intend to answer the following questions: which online communication tools are being used to engage audiences in the cultural sphere (specifically between theater companies in Lisbon)? Is there a new relationship with the public? Are online communication tools creating a new kind of community? What changes are these tools introducing in the creative process? In what way the availability of content and its archive contribute to the organization memory? Among several references, we will approach the two-way communication model that James E. Grunig & Todd T. Hunt (1984) already presented and the concept of mass self-communication of Manuel Castells (2010). Castells also tells us that we have moved from traditional media to a system of communication networks. For Scott Kirsner (2010), we have entered an era of digital creativity, where artists have the tools to do what they imagined and the public no longer wants to just consume cultural goods, but instead to have a voice and participate. The creativity process is now depending on the public choice as they wander through the screen. It is the receiver who owns an object which can be exchanged. Virtual reality has encouraged the receiver to abandon its position of passive observer and to become a participant agent, which implies a challenge to organizations: inventing new forms of interfaces. Therefore, we intend to find new and effective online tools that can be used by cultural organizations; the best way to manage them; to show how organizations can create a community with the public and how the availability of online content and its archive can contribute to the organizations’ memory.

Experimental Study And Evaluation Of Paper-Based Inkjet Electrodes For ECG Signal Acquisition

Applications involving biosignals, such as Electrocardiography (ECG), are becoming more pervasive with the extension towards non-intrusive scenarios helping targeting ambulatory healthcare monitoring, emotion assessment, among many others. In this study we introduce a new type of silver/silver chloride (Ag/AgCl) electrodes based on a paper substrate and produced using an inkjet printing technique. This type of electrodes can increase the potential applications of biosignal acquisition technologies for everyday life use, given that there are several advantages, such as cost reduction and easier recycling, resultant from the approach explored in our work. We performed a comparison study to assess the quality of this new electrode type, in which ECG data was collected with three types of Ag/AgCl electrodes: i) gelled; ii) dry iii) paper-based inkjet printed. We also compared the performance of each electrode when acquired using a professional-grade gold standard device, and a low cost platform. Experimental results showed that data acquired using our proposed inkjet printed electrode is highly correlated with data obtained through conventional electrodes. Moreover, the electrodes are robust to high-end and low-end data acquisition devices. Copyright © 2014 SCITEPRESS - Science and Technology Publications. All rights reserved.
