(Universidade Federal de São Carlos, 2013-02-21) Damas, Helton Luiz Gonçalves; Kerbauy, Maria Teresa Miceli; https://lattes.cnpq.br/4762029784021248; https://lattes.cnpq.br/2448723570436658
This paper aims to analyze how students from Course of Technology in Tourism Management evaluates the operating platform moodle seeking to prove the relationship between education and technology in accordance with the Critical Theory of Technology from Feenberg. Andrew Feenberg is one of the pioneers of distance education to create a course based on this modality in the 1980s and since then studies the distance education with relation of social studies of science and technology and his research is based on technological constructivism. Thus, the state government of Rio de Janeiro in 2000 created the CEDERJ - Center for Distance Higher Education in Rio de Janeiro - a consortium of six public universities of Rio de Janeiro. Among the courses offered by CEDERJ, can highlight the Course of Technology in Tourism Management, administered by the Federal Center for Technological Education Celso Suckow da Fonseca (CEFET / RJ). Since it is the first half of the course students have difficulties in dealing with learning technologies, and relevant to assess the perceptions that they have on the learning processes and to analyze the possibilities of student participation in the building of moodle platform, molding according to the interests of all actors involved in the course - the governing, teachers and students. As methodology, the work is a case study based on qualitative and quantitative research, data obtained through a questionnaire on line targeted at students from the five centers of the course. After interpretation and data analysis it became clear what was the perception that students have about the learning processes of the course. As a result, we can verify that students have sense evaluative notes relevant to achieving satisfactory with respect to the learning process in which they are inserted and they can constitute social agents capable of modifying educational technology.

The relationship between law and persons with disabilities existed since ancient times and is changing, albeit slowly, in search of human dignity. In the context of construction and warranty rights, scientific study was present, contributing new theories and mapping the social events. Thus, this study focuses on the rights of persons with disabilities in the Consolidated represented by scientific theses and dissertations in the Graduate Programs in the coun period between 1991 and 2009 and aims to: select the theses and dissertations in the period between 1991 and 2009 are available at the Bank of CAPES thesis and whose object of study people with disabilities and the law; analyze this scientific production, through bibliometric approach, methodology resource that allows, among other things, understand the configuration of certain knowledge areas from the analysis of the scientific production; produce bibliometric indicators of scientific output selected using the following parameters: authorship, institutional affiliation and professional profile of authors; encouragement received; regional and temporal distribution of the work; themes focused, among other , analyzing the content of selected theses and dissertations, by selecting a sample of at least one work linked to each knowledge area identified. As a theoretical framework we used the current law regarding the rights of persons with disabilities, as well as work on the analysis of scientific production and rights of people with disabilities. Regarding the methodology, the research is characterized as documentary, descriptive and analytical, based on bibliometric approach. The methodological procedures involved the following stages: a) literature review, b) survey and analysis of theses and dissertations involving thematic c) systematization and analysis of results. It was observed by the data obtained, among other things, that most research was developed between the years 2007 and 2009, and most often in programs related to the area of law and it was found that few institutions are responsible for developing most studies.
Análise da produção científica brasileira sobre o conhecimento tradicional
(Universidade Federal de São Carlos, 2013-02-21) Mello, Livia Coelho de; Rigolin, Camila Carneiro Dias; https://lattes.cnpq.br/2388584081961836; https://lattes.cnpq.br/5660714451333471
In the last two decades, the traditional knowledge has been the subject of intense discussion. This subject is studied by researchers from various areas of knowledge, generating a large number of documents, such as, journal articles, theses and dissertations. A way to evaluate the science on this subject is analyzing these documents. In this dissertation, through quantitative, descriptive and exploratory methods, it has been conducted two bibliometric analyses. The first regards the scientific production of theses and dissertations with thematic related to traditional knowledge, defended in Brazilian universities and indexed in the CAPES theses Database. The second analysis, carried out on the Web of Science database with articles about the theme Traditional Knowledge , encompassed three searches: (1) articles written by Brazilian authors; (2) international scientific production about Brazil; (3) global production of scientific documents. The bibliometric analysis pointed out that the Federal University of Santa Catarina is the Brazilian institution that has published most of the theses and dissertations on the subject, spotting the Graduate Program in Agroecosystems. Environmental studies were the ones that stood out the most, mainly the areas Ecology and Agronomy. These results suggest the treatment of traditional knowledge as a thematic subordinate to its ecological dimension.
Eletrogoniometria de punho: avaliação de sensores e procedimentos matemáticos de correção para reduzir erros de medida
(Universidade Federal de São Carlos, 2013-02-21) Foltran, Fabiana Almeida; Coury, Helenice Jane Cote Gil; https://lattes.cnpq.br/8631547579695270; https://lattes.cnpq.br/3445798406709343
The human movement record is an essential requirement for biomechanical, clinical and occupational analysis, allowing assessments of postural variation, occupational risks and improvement of preventive programs in physical therapy and rehabilitation. Electrogoniometers have been used to record wrist movements during work. However, different sizes of sensors are used, bringing difficulties to the comparison of recordings. Moreover, although of flexible electrogoniometers (EGM) are considered a reliable and accurate equipment for dynamic recordings of different joints the EGM, they are susceptible to measurement errors, known as crosstalk. There are two main types of crosstalk, crosstalk due to sensor rotation and the inherent crosstalk. Correction procedures have been proposed to correct these errors, however no study evaluating the efficiency of corrections from both procedures in subject wrist measurements was identified in the available literature. Thus, this study aims: 1) to evaluate two different sensors in order to check its performance in an anthropometric defined sample; 2) to evaluate the effects of mathematical correction procedures on: the crosstalk due to the forearm rotation, the inherent sensors crosstalk, and the combination of these two procedures. To compare the two models of sensors 13 subjects were evaluated (7 women and 6 men) who performed flexion/extension and ulnar/radial wrist movement, reaching maximum amplitude in the pronated forearm position. Two sensors measuring 65 and 110 mm of length (XM110 and XM65, respectively) and an acquisition data device (Datalog, Biometrics) were used. The sequence of movements and the sensor placement were randomized. The data were analyzed descriptively and statistically bymultivariate analysis. The intra-individual variation (root mean square RMS between trials) were calculated. The results showed there was no significant difference between the sensors for all movements. The maximum intra individual variation was 2.2°. There were significant differences between gender for wrist flexion and ulnar deviation, women have higher values than men. The maximum variability between sensors was 7.1°. Although no significant difference was identified between sensors, it was found that the sensor XM110, bigger than XM65, presented bulging during the extension. Therefore, for individuals with height up to 1.8 m, the data obtained by both sensors are comparable. In the second stage of the study we evaluate the maximum amplitude of the flexion/extension and ulnar deviation/radial wrist of 43 healthy subjects recorded by EGMs. Correction procedures were applied to the crosstalk due to the rotation of the forearm, crosstalk inherent and combining the two procedures. The results showed there was no significant difference in measurements before and after the correction procedures (P≤0.05). Furthermore, the differences between the correction procedures were below 5 ° for most cases, indicating small clinical impact on the measurements. Considering that the corrections are time consuming, require specific technical knowledge and have provided inefficient results, the correction procedures are not recommended for clinical wrist electrogoniometers recordings. Thus, improvement of equipment should be provided by the manufacturers.
Alterações bioquímico-fisiológicas em pacu (Piaractus mesopotamicus Holmberg 1887) exposto a um inseticida à base de deltametrina
(Universidade Federal de São Carlos, 2013-02-21) Rossi, Priscila Adriana; Moraes, Gilberto; https://lattes.cnpq.br/4427903557163246; https://lattes.cnpq.br/1610724290229252
The use of insecticides is increasing not only for agriculture purposes but also against threats to public health caused by insects. However, in the last few years it is possible to see a frequent replacement of current pesticides for new others, which differ in toxicity. Pyrethroid insecticides, deltamethrin is an example, are considered ideal xenobiotics due to low toxicity to mammals and birds, a wide range of targets and no biomagnification. Nevertheless, several studies report the toxic effects of deltamethrin on non-target organisms, such as fishes. In this vertebrate group, high toxicity seems to be due to an enzymatic deficiency in hydrolyzing pyrethroids and this fact can be assessed through hematologic, metabolic, neurologic, and oxidative stress investigations. Pacu, Piaractus mesopotamicus, is a freshwater fish from South America and is affected by massive use of pyrethroids. This species is widely known in the Midwest region of Brazil, wherein the largest agrochemicals use takes place. The aim of this study was the acute toxicity determination of deltamethrin (LC(I)50;48h) for pacu juveniles; evaluation of hematologic, metabolic and antioxidant defenses of pacu after 96 h of sublethal exposure to deltamethrin (10% LC(I)50;48h); evaluation of deltamethrin effects on the brain acetylcholinesterase (AChE) in vivo. The LC(I)50;48h estimated to deltamethrin in pacu juveniles was 17.32 μg L-1. In response to sublethal exposure, pacu depicted blood changes suggestive of erythropenia and dehydration. Metabolic changes included hepatic glycogenolysis, muscle proteolysis, and hyperglycemia, suggesting an overload of the energetic metabolism to serve the detoxification processes. Regarding antioxidant defenses, the occurrence of hepatic lipid peroxidation is indicative of oxidative stress with depletion of non-enzymatic antioxidants and alterations in antioxidant enzymes activity. Also, deltamethrin depicted AChE inhibition in fish exposed to sublethal concentrations.
Cinemática escapular : confiabilidade e efeitos pré e pós uma manipulação torácica em sujeitos com e sem sintomas de impacto - um estudo controlado randomizado
(Universidade Federal de São Carlos, 2013-02-21) Haik, Melina Nevoeiro; Camargo, Paula Rezende; https://lattes.cnpq.br/7602596349127054; https://lattes.cnpq.br/8240155487619947
Background: There is a lack of studies that evaluated within day and between day reliabilities of 3-D scapular kinematics during elevation and lowering of the arm in different shoulder conditions, as well as studies about low-amplitude and high-velocity thoracic spine manipulation (TSM) effects on scapular kinematics in subjects with shoulder dysfunctions. Objective: To establish within day and between day reliability of scapular motion during elevation and lowering of the arm and at rest position and to evaluate the immediate effects of a TSM on pain and scapular kinematics during elevation and lowering of the arm, both in subjects with and without shoulder impingement syndrome (SIS). Methods: Kinematic data were collected using Flock of Birds® electromagnetic device. Subjects were divided in 2 groups: control and impingement. For reliability kinematic data were collected during elevation and lowering of the arm and at rest position on 2 different occasions separated by 3 to 5 days. Forty-nine subjects were tested for within day reliability. Forty-three subjects were reassessed for between day reliability. For kinematic evaluation pre- and ppost-manipulation, scapular kinematics was collected during elevation and lowering of the arm before and immediately after the intervention. Numeric pain rating scale was used to assess shoulder pain during arm movement at pre- and post- intervention. Fifty subjects (31.76 ± 10.91 years) with SIS and 47 subjects (25.76 ± 5.01 years) asymptomatic for shoulder dysfunctions were randomly assigned to one of the groups: manipulation or sham. Results: There was very good within day reliability for assessing scapular internal and upward rotations and tilt from both groups during elevation and lowering of the arm (ICC=0.92-0.99). In general, there was good between day reliability for assessing scapular motion during elevation and lowering of the arm from both groups (ICC=0.54-0.88). There was also good and very good between day reliability for assessing scapular rest position in both groups (ICC=0.66-0.95). Study 2: Subjects with SIS experienced reduced shoulder pain (from 3.29 to 2.45, p<0.01) during arm movement immediately after TSM. Subjects with and without SIS who received TSM and asymptomatic subjects who received sham intervention showed significant increase in scapular upward rotation at post-intervention. Increase in scapular anterior tilt at postmanipulation was also observed in asymptomatic subjects who received TSM. Conclusion: Flock of Birds® electromagnetic tracking system is a reliable device for measuring 3-D scapular motion during elevation and lowering of the arm and at rest position in subjects with and without impingement symptoms over time. TSM is associated with improved shoulder pain and scapular upward rotation in subjects with SIS. Although with questionable clinical relevance, TSM may not be immediately favorable to scapular tilt in asymptomatic subjects.
O campo científico, os conflitos e relações de poder no trabalho de professores de uma universidade pública
(Universidade Federal de São Carlos, 2013-02-21) Graetz, Carla Fabiana; Silva, Eduardo Pinto e; https://lattes.cnpq.br/3492708361349827
The main target in this dissertation is to identify the constitutive elements of the dynamic in the scientific field, standing out the experience and the point of view of professors on the conflicts and relations of forces. There was an approach to a postgraduate course on humanities of a renowned Brazilian public university. Twelve semi-structured interviews were conducted about life history and scientific academic trajectory. The professors were intentionally selected. Professors, who entered in the institution in different historical moments (before and after 1995), were interviewed. These professors were also in different stages in their careers and they also presented different hierarchical positions in the institution and also in the scientific field. There were also pilot interviews with a professor from another institution and two complementary ones, one of which with a university worker and another one with a student, which guided this research about the procedure and questions of the interviews. The analysis of the content of the interviews was made by reading, rereading and gradual building of analysis categories that allowed pointing inferences and interpretations. Two categories of analysis were indicated: work, sociability and subjectivity; and field, university practices and relations of forces. The analysis of the interviews was complemented with some documents (inter alia, meetings minutes, lattes CV, data from the institution website) that allowed us to consider, within the limits of the ethic commitment of not identifying the researched institution, some features of its institutional culture, its faculty profile and also of its sample. It was used as theoretical background Bourdieu‟s concepts of fields, capital and habitus, as well as studies on Brazilian public universities and also studies of other authors that approach themes related to the subject of our research. It started from the hypothesis of the reconfigurations of the public universities under the guidelines of the State Reform that took place especially after 1995. It was considered that could be worsening clashes and disputes in obtaining and also distributing the scientific capital due to the postgraduation model that is being consolidated. The results pointed out to the inseparability, contradictions and clashes between sociability and subjectivity under the mediation of work. It was pointed to epistemological and political conflicts in the scientific field and relations of forces permeated by competitiveness and individualism. The internalized provisions of the professors were understood as formed in a variety of their lifelong socialization processes and reconstituted in a more or less conflicting way from their insertion in the scientific field and in their current historical moment, in which the universities practices tend to be reconfigured under the aegis of the instrumental rationality of the evaluation model of the professors production performance and also of post-graduation programs. It was evident that there was a dialectical relationship between habitus and field, as the professors are constitutive part in the scientific field, the same way that they extract elements that influence their subjectivity, (con) forming it, according to each case, in different ways, to the productive sociability. The professors need to tacitly accept the rules in the scientific field and the established evaluation parameters of productivity, in order to remain therein, even that, many times, the subjectivity and the habitus clash with the productive sociability.
