Abstract The aim of this paper is to present the development of a skateboard for a physically disabled child. The design presented in this study was motivated by an existing request of a local school that wanted to provide one of its students, a lower-limb amputee, with a more efficient method of transportation. Therefore, the design of an adapted skateboard, that values a healthy posture and an alternative propulsion system was proposed. For the product design, a user-centered methodology was applied based on the Project Development Orientation Guide. This methodology is divided in 8 stages and starts at the market opportunities and ends in the product testing. Hence, strategies of research and idea generation, such as articles and patents research, questionnaires, morphological matrix and SCAMPER tool, were used to develop a solution with a 3D model. With the model, a static simulation was performed through a finite element analysis method to validate the design and define the product’s dimension. The development of a product focused on the real needs of the user was highly approved. However, the user centered method presents significant challenges, especially dealing with a child and considering ethical standards in scientific research. The adapted skateboard represents a life quality improvement for the user and needs to be prototyped and tested for validation of the presented solution.

Abstract REFERENCE: H. M. R. Aboutorabi and L. Kung, “Application of Coupled Structural Acoustic Analysis and Sensitivity Calculations to a Tire Noise Problem,” Tire Science and Technology, TSTCA, Vol. 40, No. 1, January – March 2012, pp. 25–41. ABSTRACT: Tire qualification for an original equipment (OE) program consists of several rounds of submissions by the tire manufacturer for evaluation by the vehicle manufacturer. Tires are evaluated both subjectively, where the tire performance is rated by an expert driver, and objectively, where sensors and testing instruments are used to measure the tire performance. At the end of each round of testing the evaluation results are shared and requirements for performance improvement for the next round are communicated with the tire manufacturer. As building and testing is both expensive and time consuming predictive modeling and simulation analysis that can be applied to the performance of the tire is of great interest and value. This paper presents an application of finite element analysis (FEA) modeling along with experimental verification to solve tire noise objections at certain frequencies raised by an original equipment manufacturer (OEM) account. Coupled structural-acoustic analysis method was used to find modal characteristics of the tire at the objectionable frequencies. Sensitivity calculations were then carried out to evaluate the strength of contribution from each tire component to the identified modes. Based on these findings changes to the construction were proposed and implemented that addressed the noise issue.

The purpose of this study was to determinate , using the Finite Element Analysis Method, the mechanical stress in a solid body , temporary molar restored with the self-curing GC material. The originality of our study consisted in using an accurate structural model and applying a concentrated force and a uniformly distributed pressure. Molar structure was meshed in a Solid Type 45 and the output data were obtained using the ANSYS software. The practical predictions can be made about the behavior of different restorations materials.

Abstract This research aimed to find out to the correlation between social support with physically disabled in the Physically disabled rehabilitation center, to know the significant of social support function to autonomy of individual.The research was held in Physically disabled rehabilitation which subject were taken from 18 -35 years old of 120 people of physically disabled. To gain the data, the researcher used questionnaire method. The sample is taking with the purposive sample. Product moment Correlation analysis method was applied to analyze the data and it reached 5% of significance.The result of the data analysis showed that the social support  had a significance effect to the autonomy individual  with the value of r =0,399, (p>0,05), also give significant effect to it. Adjusted value (R2) of 0,159 means that 15,9% of variation of autonomy individual could be explained with the variation of social support. Meanwhile, 84,1% was caused by other factors. Keywords: social support and self-reliance

Aims The aim of this study is to evaluate the effects of the chincup appliance used in the treatment of Class III malocclusions, not only on the mandible or temporomandibular joint (TMJ) but also on all the craniofacial structures. Materials and Methods Chincup simulation was performed on a three-dimensional finite element (FE) model. 1000 g (500 g per side) force was applied in the direction of chin-condyle head. Nonlinear FE analysis was used as the numerical analysis method. Results By the application of chincup, stresses were distributed not only on TMJ or mandible but also on the circummaxillary sutures and other craniofacial structures. Conclusions Clinical changes obtained by chincup treatment in Class III malocclusions are not limited by only mandible. It was seen that also further structures were affected.
