The main goal of this work is the analysis of theoretical and methodological aspects of speech melody variation (intonation), with special reference to the pronunciation of one speaker. In order to carry on this study, different types of sentences (declarative, questions, etc.) and the intonational focus as well as the speaker‟s attitude (irony, emphasis, etc.) were observed and analyzed with special acoustic software (PRAAT) and with an auditory analysis of a text read by the subject. The aim of this work is to verify whether the acoustic analysis matches with the auditory perception phonetically, according to M.A.K. Halliday‟s methodology, following Cagliari (2007), who adapted Halliday‟s model to describe the intonation of Portuguese

Disorders in gait are identified in Parkinson’s disease patients. As a result, the capacity of walking independently and the interaction with the environment can be impairment. So, the auditory cues have been utilized as a non-pharmacological treatment to improve the locomotor impairment of the PD patients. However, these effects were observed in the regular lands and it’s not known the effects of auditory cues in gait during avoidance obstacles that could be more threaten for these patients. Yet, few studies in the literature compare the Parkinson’s disease patients with the older adults during the locomotor tasks and obstacle avoidance in association with the effects of auditory cues. The aim of the study is to compare the effects of the auditory cues in the gait and during obstacle avoidance in PD patients and older adults. 30 subjects distributed in two groups (Group 1 - 15, Parkinson’s disease patients; Group 2 - 15, healthy older adults) are going to participate of this study. After the participation approval, the assessment of clinical condition will be done by a physician. So, to investigate the locomotor pattern, it will be done a kinematic analysis. The experimental task is to walk on 8 m pathway and 18 trials will be done (6 for the free gait and 12 for adaptive gait). For the adaptive gait, two different obstacle heights will be manipulated: high obstacle (HO) and low obstacle (LO). In order to verify possible differences between the groups and the experimental condition, multivariance tests will be used with a significance level of 0.05. MANOVA revealed effect of condition and task. Thus, with DA, we observed an increase in cadence and reduced single support and stride length. When the tasks were compared, it was observed that the LO task, subjects had lower velocity and stride length... 9Complete abstract click electronic access below)

This work presents the development of a graphical interface to the Lock-in Amplifier, which is used in physiological studies on the motility of the gastrointestinal tract in rats and signal processing. With a simple and low cost instrumentation, the resources offered by the virtual interface of LabVIEW software allows the creation of commands similar to the actual instrument that, through communication via standard serial port, transmits data between a PC and peripheral device performing specific and particular needs in the amplifier. Created for the lock-in amplifier model SR830 Stanford Research Systems, the remote manipulation gives the user greater accessibility in the process of configuration and calibration. And, since the software is installed, there is the advantage of eliminating the need of purchase new devices to upgrade the system. The commands created were made to perform six basic modifications that are used in routine of the Biomagnetism Laboratory. The instrumentation developed has the following controls: Amplitude, Frequency, Time Constant, slope low pass filter, sensitivity and offset

In this project the Pattern Recognition Problem is approached with the Support Vector Machines (SVM) technique, a binary method of classification that provides the best solution separating the data in the better way with a hiperplan and an extension of the input space dimension, as a Machine Learning solution. The system aims to classify two classes of pixels chosen by the user in the interface in the interest selection phase and in the background selection phase, generating all the data to be used in the LibSVM library, a library that implements the SVM, illustrating the library operation in a casual way. The data provided by the interface is organized in three types, RGB (Red, Green and Blue color system), texture (calculated) or RGB + texture. At last the project showed successful results, where the classification of the image pixels was showed as been from one of the two classes, from the interest selection area or from the background selection area. The simplest user view of results classification is the RGB type of data arrange, because it’s the most concrete way of data acquisition

This study aimed to develop a computer program which systematizes the structural shielding design calculation in diagnostic radiology facilities. For this purpose methodology of the National Council of Radiation Protection and Measurements (NCRP 147[5]) was used. By comparative statistics studies, it was verified if reference parameters values suggested by the US publication correspond to the average national values. The World Wide Web was chosen because of its characteristics as a powerful mean of communication, especially in terms of the wide variety of useful resources and easy access. To compare the reference values of some parameters proposed by NCRP 147 to Brazilian average, studies about the normalized workload per patient, performance of X-ray tube and primary air kerma, unshielded, at one meter from the focal point of the X-ray tube were made. Through this research, relative differences were found. In workload values this differences reached up to 50% in mammography compared to those presented by the NCRP 147; in X-ray tube performance the percentage differences reached 69% in dental radiology, and air kerma results amounted 31% in fluoroscopy. This demonstrates the importance of validation of international protocols to local realities

Worldwide, growth is seen in the elderly population, which has prompted the use oftechnologies of care that include all stages of life and for that use, it is necessary toprepare professionals to meet this growing demand population. This work aims to understand how old people feel by their condition and identify how old people perceive this treatment in the Family Health Unit. The research is characterized asqualitative and Minayo second analysis was used Bardin. After, thematicinterviews, it was possible to appreciate the topics: Good, dissatisfaction through the life and likes / dislikes of the service unit. This work can be seen that the elderlywho were well, allied to good living with this family, with spouses, autonomy, respect they encounter in society. And when compared with those who have a complaint, we find that lack of family and age restrictions and diseases are the main complaints

A simple and sensitive method using solid phase microextraction (SPME) and liquid chromatography (LC) with heated online desorption (SPME-LC) was developed and validated to analyze anticonvulsants (AEDs) in human plasma samples. A heated lab-made interface chamber was used in the desorption procedure, which allowed the transference of the whole extracted sample. The SPME conditions were optimized by applying an experimental design. Important factors are discussed such as fiber coating types, pH, extraction time and desorption conditions. The drugs were analyzed by LC, using a C18 column (150 mm 4.6 mm 5 mm); and 50 mmol L1 , pH ¼ 5.50 ammonium acetate buffer : acetonitrile : methanol (55 : 22 : 23 v/v) as the mobile phase with a flow rate of 0.8 mL min1 . The suggested method presented precision (intra-assay and inter-assay), linearity and limit of quantification (LOQ) all adequate for the therapeutic drug monitoring (TDM) of AEDs in plasma.

This study aimed to investigate how people with hearing disability perform tasks of distances estimation for locomotion and navigation when deprived of effective perceptual and proprioceptive information. For this, participants with hearing disability went three distances being the first and second 100 meters and the third 140 meters (triangulation) from a source point in an inverted L open field trajectory and then returned to the origin, and the first two were driven by a researcher guide with adapted GPS coordinates of the study, and the third being three free-form sessions, the first one without any perceptual and proprioceptive restriction, the second without visual perception, and the third on the wheel-chair, that is, without proprioception. The results showed that people with hearing disability without the knowledge of the path do not possess satisfactory accuracy but when they learn the way even with the restriction of visual perception and proprioception they can return to the starting point in a task of triangulation. The "t" students test with a significance level of 5% (2.131) indicates significant differences between the first task without any perceptual restriction and the third where they performed in the wheelchair. To achieve these results we used remote monitoring via GPS and the TrackMaker software.
