Relação entre potenciais evocados auditivos de média latência e distúrbio de processamento auditivo: estudo de casos

The Auditory Evoked Middle Latency Response is one of the most promising objective tests in audiology and in revealing brain dysfunction and neuro-audiologic findings. The main advantages of its clinical use are precision and objectivity in evaluating children. This study aimed to analyze the auditory evoked middle latency response in two patients with auditory processing disorder and relate objective and behavioral measures. This case study was conducted in 2 patients (P1 = 12 years, female, P2 = 17 years old, male), both with the absence of sensory abnormalities, neurological and neuropsychiatric disorders. Both were submitted to anamnesis, inspection of the external ear canal, hearing test and evaluation of Auditory Evoked Middle latency Response. There was a significant association between behavioral test and objectives results. In the interview, there were complaints about the difficulty in listening in a noisy environment, sound localization, inattention, and phonological changes in writing and speaking, as confirmed by evaluation of auditory processing and Auditory Evoked Middle Latency Response. Changes were observed in the right decoding process hearing in both cases on the behavioral assessment of auditory processing; auditory evoked potential test middle latency shows that the right contralateral via response was deficient, confirming the difficulties of the patients in the assignment of meaning in acoustic information in a competitive sound condition at right, in both cases. In these cases it was shown the association between the results, but there is a need for further studies with larger sample population to confirm the data.

Habilidade auditiva em criança desnutrida

PurposeTo characterize and compare the performance of malnourished children and normal children in auditory processing. MethodThe sample comprised 30 children from five to ten years old, both genders, being 15 malnourished children (G1) and 15 children with adequate nutritional status, as a control group (G2). The groups were paired according to gender, age and grade level. Both groups underwent peripheral and central auditory assessment, noting that malnourished children had higher changes in the skill of sequencing score for verbal and nonverbal when compared to normal children, and the same occurred in closing skills and background figure. ResultRegarding the degree of auditory processing disorder, it was more severe in malnourished children. ConclusionChildren with malnutrition have higher frequency alterations in auditory abilities when compared to normal children, being the temporal ordering skills, auditory memory, selective attention, figure-ground and closing the most affected skills.

O padrão de compressão de video MPEG moving picture experts group

This work focuses on the study of video compression standard MPEG. To this end, a study was undertaken starting from the basics of digital video, addressing the components necessary for the understanding of the tools used by the video coding standard MPEG. The Motion Picture Experts Group (MPEG) was formed in the late '80s by a group of experts in order to create international standards for encoding and decoding audio and video. This paper will discuss the techniques present in the video compression standard MPEG, as well as its evolution. Will be described in the MPEG-1, MPEG-2, MPEG-4 and H.264 (MPEG-4 Part 10), however, the last two will be presented with more emphasis, because the standards are present in most modern video technologies, as in HDTV broadcasts

A leitura na perspectiva de Bakhtin e suas possibilidades na formação do leitor: na educação infantil e no primeiro ano do ensino fundamental

Overall, in Brazilian schools, the concept of reading does not take into account its possibilities and its meaning for life. But read is assigning meaning to something , make sense, interact with the text read. Thus, the present study addresses the mechanical reading, that without contextualization, performed on a technique by joining letters and syllables loose and also reading social use, consisting of statements, dialogism , polyphony and heteroglossy. It is known that the mechanical reading brings undesirable consequences, including learning problems, such as lack of attention, concentration, memory, imagination. When the reading is taught in a systematic way, with only the goal of the code decoding of written language, destroys social perspectives and intellectual development. It is common, when you offer the children a book, there the difficult disinterest of textual interpretation, because there is no attribute meaning to the content, and even the ability to interact with the text. With the interest in studying the dialogic reading this and the statements and genres, the present study was based on several authors: Bakhtin (1988, 2000), Schneuwly and Dolz (2000), Faraco (2009) and Ponzio (2009) Jolibert (1994), Bajard (2002; 2007) Foucambert (1997) Martins ( 1985) and Smith ( 1999). Aim for this study the following research question: what are the contributions of Mikhail Bakhtin's theory to the teaching of reading from kindergarten through the first grade of elementary school? Our hypothesis is that if they are guaranteed to pre -school and elementary school beginners diversified materials and new approaches in teaching reading and encouragement to her, will be developed in children a taste for the act of reading, so that they can assign meaning and significance, making reading part of their lives...

A BCH code and a sequence of cyclic codes

This study establishes that for a given binary BCH code C0 n of length n generated by a polynomial g(x) ∈ F2[x] of degree r there exists a family of binary cyclic codes {Cm 2m−1(n+1)n}m≥1 such that for each m ≥ 1, the binary cyclic code Cm 2m−1(n+1)n has length 2m−1(n + 1)n and is generated by a generalized polynomial g(x 1 2m ) ∈ F2[x, 1 2m Z≥0] of degree 2mr. Furthermore, C0 n is embedded in Cm 2m−1(n+1)n and Cm 2m−1(n+1)n is embedded in Cm+1 2m(n+1)n for each m ≥ 1. By a newly proposed algorithm, codewords of the binary BCH code C0 n can be transmitted with high code rate and decoded by the decoder of any member of the family {Cm 2m−1(n+1)n}m≥1 of binary cyclic codes, having the same code rate.

Goppa codes over certain semigroups

A Goppa code is described in terms of a polynomial, known as Goppa polynomial, and in contrast to cyclic codes, where it is difficult to estimate the minimum Hamming distance d from the generator polynomial. Furthermore, a Goppa code has the property that d ≥ deg(h(X))+1, where h(X) is a Goppa polynomial. In this paper, we present a decoding principle for Goppa codes constructed by generalized polynomials, which is based on modified Berlekamp-Massey algorithm.

A Note on Linear Codes over Semigroup Rings

In this paper, we introduced new construction techniques of BCH, alternant, Goppa, Srivastava codes through the semigroup ring B[X; 1 3Z0] instead of the polynomial ring B[X; Z0], where B is a finite commutative ring with identity, and for these constructions we improve the several results of [1]. After this, we present a decoding principle for BCH, alternant and Goppa codes which is based on modified Berlekamp-Massey algorithm. This algorithm corrects all errors up to the Hamming weight t ≤ r/2, i.e., whose minimum Hamming distance is r + 1.

Alfabetização de jovens no 6º ao 9º ano na perspectiva freireana: uma intervenção educativa para a vida na escola e no mundo

By showing how the problem of illiteracy is present among adolescents 11-14 years of age, attending school regularly, and realize how much this problem affect your life not only in school but also in their participation in society, it has set the aim of this research to alphabetize and write the lyrics registered adolescents of elementary school (6th to 9th grade) in a public school, by the Paulo Freire alphabetization method. The type of research that best responds to the proposed objective was action research with a qualitative approach. The data obtained from this research were analyzed in three topics: the search and selection of generating words, technical literacy and consciousness of each generating words (encoding and decoding of the situation experienced this situation with critical weight, pragmatic), and in the end, the analysis of the production of genre personal letter. The survey results indicate that, indeed, it is possible to write the lyrics and literate adolescents with Freirean literacy method. Also indicate the need to continue this work with the subjects of this research to develop linguistic and discursive skills to dominate the genre studied, both in the phenomenon of literacy, as in the write the lyrics. The results also point to another need, which is the extension of this research work in the community and other schools of the city, who have this problem of having teenagers in Elementary Education II, without being literate, as an alternative to overcome this major problem of illiteracy

A low-power silicon-on-insulator PWM discriminator for biomedical applications

A CMOS/SOI circuit to decode PWM signals is presented as part of a body-implanted neurostimulator for visual prosthesis. Since encoded data is the sole input to the circuit, the decoding technique is based on a double-integration concept and does not require dc filtering. Nonoverlapping control phases are internally derived from the incoming pulses and a fast-settling comparator ensures good discrimination accuracy in the megahertz range. The circuit was integrated on a 2 mu m single-metal SOI fabrication process and has an effective area of 2mm(2) Typically, the measured resolution of encoding parameter a was better than 10% at 6MHz and V-DD=3.3V. Stand-by consumption is around 340 mu W. Pulses with frequencies up to 15MHz and alpha = 10% can be discriminated for V-DD spanning from 2.3V to 3.3V. Such an excellent immunity to V-DD deviations meets a design specification with respect to inherent coupling losses on transmitting data and power by means of a transcutaneous link.

Geografia e imagem publicitária: um diálogo possível

The aim of present work is the interpretation of a Coca Cola soft drink advertising image that is shown on a billboard in the city of Presidente Prudente, in São Paulo state. The billboard shows a scene of the video titled Happiness Factory which was presented on television in 2008. Decoding this kind of image, which is integrated to the theoretical and methodical option, favors the visual perception of shapes and their meanings as a reading of the image and the inclusion of the studies of phenomenology of cultural geography to the social reality could reveal some other dimensions, such as the symbolic, the imaginary, the aesthetic ones.This fact will contribute to widen the social trait of Geography and it represents our object of study.The reading will be done after some reflexion on the function of an external advertisement, that is, within the urban context of Presidente Prudente when refering to billboard being studied. It will also be discussed the importance of becoming a critical reader when interpreting advertising messages presented by the communication means in general.

Relações entre proeminência facial nas fotos do Orkut e o perfil dos usuários

Relationship Between Facial Prominence of Orkut’s Photos and the Users’ Profile This research aimed to verify the relation between facial prominence index (FPI) and the profile of 600 users of Orkut. The results demonstrated that in all evaluated segments the average of male facial prominence was higher than the female; women increase the prominence while men decrease it as they become older and university graduates women have presented higher prominence than high school graduates. Significant differences were also found in the categories of humor when comparing the FPI between the genders and between persons of the same gender. In summary, the results indicate that the determinant factors for the facial prominence presented at Orkut are probably related to both biological and cultural aspects.
