A Strategy For The Development Of The Medical Devices National Innovation System [uma Estratégia De Desenvolvimento Para O Sistema Nacional De Inovação De Produtos Médicos]
No full textThis paper presents a proposal of a program for the development of the Brazilian National Innovation System for Medical Products (SNIPM) under the National Health System (SUS) integrated and aligned with the actions of the Brazilian Ministry of Health. Clinical engineering knowledge and tools allowed performing a differentiated socio-economic analysis of the sector, the systematization and the perception of actors and factors that induce or retard the growth of the technology sector. In this article, the medical devices sector in Brazil was first contextualized to in the light of current national and global socio-economic conjuncture, in order to characterize it as a major inducer of innovative activities. The definitions and theories about the National Innovation Systems are described, followed by a discussion of the specifics of SNIPM in Brazil, with its actors, including their duties and responsibilities. The methodology for the collection and analysis of economic data, were shown, in order to characterize the importance of this sector to the national economy and its potential to induce the rising of innovative technologies whithin the SNIPM. The analysis of industry data is presented, which attempts to present and comment on some industry data collected during a survey. In the Results section, it is presented the design of a program used to to catalyze the development of the SNIPM considering the technological demands and priorities of the SUS and the target markets of the productive sector. The proposed program, which was developed and implemented within the Brazilian Ministry of Health, can become one of the tools within the SUS to strengthen and modernize the sector of medical equipments and materials, aiming to increase the innovative capacity of firms and change its competitive standing.282124139Albuquerque, E.M., Cassiolato, J.E., As especificidades do sistema de inovação do setor saúde (2002) Revista de Economia Política, 22 (4), pp. 134-151Arruda, M., Velmulm, R., Hollanda, S., Inovação tecnológica no Brasil: A indústria em busca da competitividade global (2006) São Paulo: ANPEI, p. 117Bobbie, B., Health Technology assessment: Challenges and solutions for medical devices (2010) Canada: Cook MedicalRegula direitos e obrigações relativos à propriedade industrial (1996) Diário Oficial da República Federativa do Brasil, pp. 8353-8366. , Brasil.

Projected Costs For Acquisition Of Equipment Ultrasound In Medical Clinics [projeção De Custos Para Aquisição De Equipamentos De Ultra-som Em Clínicas Médicas]
No full textThe objective of this work is to present a projection of costs for ultrasound scanning equipment acquisitions by medical imaging clinics and to understand how these acquisitions affect the final value of ease exam. In order to meet customer demands for the newest technology, medical imaging clinics substitute their equipments in shorter periods of time, trying to follow the launching of more sophisticated products. The cost of the anticipation of ultrasound scanning replacement was projected to verify how it affects the clinic budget. According to medical imaging clinics market profile, two factors of great importance in ultrasound scanning acquisition have been identified: the cost of tax loans paid and the monthly demand of imaging services. Medical imaging clinics seldom have the preoccupation to verify the impact of these factors in the equipment replacement, which may cause damage to their financial health. For this study data from 04 clinics, that have together 12 equipment acquisition processes in a given period, have been collected and analyzed. The clinics are located in the city of Campinas (SP, Brazil), which has a population greater than 1 million people. Each chosen clinic monthly makes, by ultrasound equipment, from 400 to 700 exams. The results showed that each exam costs from 7.22, just due to ultrasound scanning equipment acquisition. When the anticipation of medical equipment replacement was combined to the cost of tax loans paid and the monthly demand of imaging services, the projected cost of an imaging exam reached values between 20.00. © Springer-Verlag Berlin Heidelberg 2007.18816819Ewing, B.T., Kruse, J.B., Thompson, M.A., (2002) Linkages Within the Health Care Industry, , Texas: Texas Tech UniversityMartins, D.S., (2000) Custos e Orçamentos Hospitalares, , SP: ed.

Multichannel Arbitrary Waveform Beamformer Transmitter For Experimental Research Activities Of Ultrasound [beamformer De Transmissão Multicanal De Forma De Onda Arbitrária Para Atividades De Pesquisa Experimental Do Ultrassom]
No full textThis paper presents the development of a digital beamformer transmitter system for generation of arbitrary ultrasound waveforms, specifically designed for research purposes. The proposed architecture has 8 independent excitation channels and uses an FPGA device (Field Programmable Gated Array) for electronic control channel generation of ultrasonic acoustic beam transmission. The system allows operation in pulse-echo mode, with pulse repetition rate of excitation between 62.5 Hz and 8 kHz, or single pulse, center frequency between 500 kHz and 20 MHz, excitation voltage between -100 and +100 V, and individual control of amplitude apodization, phase angle and time delay trigger. The mathematical method for determining the digital signals of excitation is presented and validated through practical results for waveform generation with Gaussian profile and center frequency of 20 MHz, in a load formed by a 220 pF capacitor in parallel with a resistor of 1 kΩ. The results show that the proposed flexible and fully programmable architecture, can support the development of new algorithms and sophisticated processing techniques of the transmission beamformer.236667678(2010) Cyclone III Device Handbook I-II.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
