Redução do medo durante o tratamento odontológico utilizando pontas ultrassônicas

Over the last few years, new technologies have been developed to making cavity preparations, among which the diamond burs CVDentus® (CVDentus, São José dos Campos, Brazil) are outstanding. These points are produced by chemical deposition from the vapor phase, forming a single diamond stone, with greater durability than the conventional diamond burs. Coupled to the ultrasound appliance, they have several clinical applications in Dentistry with advantages over conventional rotary instruments, such as lower pressure, noise, vibration and heat, as well as reducing the need to use local anesthesia, contributing to minimize patient’s fear and anxiety. The aim of this study was to present the complete restorative dental treatment performed with this system in a child patient with a prior history of non-cooperative behavior. The use of this new technology offered the patient greater comfort, making it possible recondition the patient’s attitude to dental treatment, in addition to favoring conservative cavity preparations to be made.

Evasão no cursinho pré-vestibular da FCA/UNESP: a interpretação do aluno evadido

The popular cram schools are voluntary initiatives aimed at people who are not able to afford the cost of private cram schools. The FCA popular cram school integrates a large project from UNESP, which has 30 cram school distributed throughout Sao Paulo State and located in different University units. Among the problems found in popular cram schools, school evasion, characterized when the student quits the course and is very common in this context. Thus, the aim of this work was to identify the profile of the drop out student from the FCA cram school as well as to know the reasons that led them to leave. The survey was conducted in two phases: 1) students´ profile when entering the cram school, through a structured questionnaire, 2) semi-structured interviews by telephone with all the drop out students, trying to identify the reasons that led them to abandon the course. The statistical analysis used was descriptive. Among the reasons that led them to leave, it was found that 65% of the students attributed this attitude to external factors as opposed to 35% who put the internal factors as the decisive reason of their departure. Some of the factors that could be attest for the FCA cram school evasion are: primarily, the heterogeneity of students and their need to work in order to support themselves and their family; students lack of motivation about a long-term success; lack of family encouragement; the difficulty of the student to establish significant personal links with cram school staff and the fact that the professors are mostly undergraduate students from different courses in different areas, with little didactic-pedagogic preparation and inability to work with students' heterogeneity.

A formação de professores e o uso pedagógico da Web 2.0: a visão de estudantes de licenciatura

The aim of this paper is to discuss the importance of training teachers to use Web 2.0 in the classroom. Its intention was to fi nd out whether students are familiar with the main Web 2.0 resources and know how to exploit their potential in the development of teaching activities. In addition to the literature review, we developed a fi eld exploratory-descriptive research. The research was held in a private university located in the city of Bauru (São Paulo State, Brazil). We selected 213 students enrolled in “Supervised Training III” course, which is part of the teacher training curriculum available for students in the second year of undergraduate course. Results concluded that the students surveyed have access to computers and the Internet, are relatively skilled in handling the available tools and recognize the importance of including them in the teaching and learning process. The students demonstrate diffi culty using the web in a didactic manner, particularly the Web 2.0, which involves a focus on users and collaboration. Therefore, the article points to the need to rethink teacher training courses in order to include practical activities aimed at the use of technology as a teaching resource.

The interactive whiteboard in primary school: a case study of a brazilian district school

Interactive whiteboards (IWB) consist of a set of technological equipment organized in order to fulfill a specific task, enabling the development of didactic activities. Because they are associated to computers’ potentiality, interactive whiteboards can provide bigger interactivity between: teacher and students, students and content, and among students. This work’s main objective is to present some of the results yielded from a research related to the way students perceive interactive whiteboards in the classroom. In order to analyze the IWB usage dynamics, some educational applications in the field of mathematics were applied in the 3rd grade of elementary school. Aside from observation, video recordings were made and students were interviewed about the interactive whiteboard, in order to understand how these students observe and engage with the technological tool. IWB do not transform classroom’s reality by themselves, however, their physical presence and usage amount to external reinforcement can change student’s behavior positively.

Unscented Kalman Filter Applied to the Spacecraft Attitude Estimation with Euler Angles

The aim of this work is to test an algorithm to estimate, in real time, the attitude of an artificial satellite using real data supplied by attitude sensors that are on board of the CBERS-2 satellite (China Brazil Earth Resources Satellite). The real-time estimator used in this work for attitude determination is the Unscented Kalman Filter. This filter is a new alternative to the extended Kalman filter usually applied to the estimation and control problems of attitude and orbit. This algorithm is capable of carrying out estimation of the states of nonlinear systems, without the necessity of linearization of the nonlinear functions present in the model. This estimation is possible due to a transformation that generates a set of vectors that, suffering a nonlinear transformation, preserves the same mean and covariance of the random variables before the transformation. The performance will be evaluated and analyzed through the comparison between the Unscented Kalman filter and the extended Kalman filter results, by using real onboard data.

TIME-OPTIMAL GEOMAGNETIC ATTITUDE MANEUVERS OF AN AXISYMMETRICAL SPINNING SATELLITE

A formulation used to determine the time-optimal geomagnetic attitude maneuvers subject to dynamic and geometric constraints is proposed in this paper. This was obtained by a direct search procedure based on a control function parametrization method, using linear programming to obtain numerical suboptimal solutions by linear perturbation. Due to its characteristics it can be used in small computers and to generate computer programs of general application. The dynamic modeling, the magnetic torque model and the suboptimal control procedure are presented. Simulation runs have verified the feasibility of the formulation thus derived and have shown a notable improvement in performance.
