All our day’s work in this world of science is done with useful data. These useful data or information is extracted from raw facts. From the information, knowledge is gained. This knowledge is used by the customers for beneficial outcome. Here comes the concept of data mining. An important query arises as how to preserve these data. This concept is called as Privacy Preserving with Data Mining (PPDM). Many PPDM techniques are available to protect the data. The PPDM technique is useful in fields like medicine, forensics, defence, etc to preserve the confidential data. The existing techniques protect the secret data either by perturbing or by hiding them. Moreover, most of the techniques focus only on the numerical data. Very few perturbation techniques like translation, multiplicative and rotation perturb the images. But these techniques are very easily attacked by third parties since the transformation is a linear one. The Research Work aims to overcome the drawbacks of the existing perturbation techniques. The main objective of the Research Work is to improve the privacy level of the images by implementing a Random Projection (RP) technique. The remarkable features and benefits of the RP technique are pinpointed.

In this article we are going to present a «Biospheres” practice. It evolved as a result of integrating our formative experiences in Bioenergetics Analysis with the «Dynamic Sphere Postural Reorganization” (Esferodinamia Reorganización Postural, which will be referred to as «RP” technique). We describe the sphere (large rubber ball) qualities and how it can be helpful for body psychotherapy interventions. Finally, we look into two cases using this clinical tool. The sphere becomes an element that facilitates clinical and educational work in the contemporary Bioenergetic field.

Rapid Prototyping (RP) technique was used to prepare porous Ti6Al4V with designed structures. Firstly, a 3-D interconnected porous wax mold with uniform pore size and porosity was designed by computer aided design (CAD), and fabricated by 3-D printing machine, then an aqueous Ti6Al4V slurry prepared from Ti6Al4V powder and binders was cast in these molds. The green bodies were subjected to drying, debinding and finally sintering at a high temperature and a high vacuum to obtain porous Ti6Al4V. Optical microscopical observation, scanning electronic microscopical observation, mechanical test were performed on the obtained porous Ti6Al4V with regard to the porous structures and mechanical properties. The porous Ti6Al4V made by RP technique posses designed structure with uniform pore size, porosity and interconnection. With the computer aided design, it is easy to improve the mold structure with predicted or controlled macrostructure and microstructure according to the custom requirement.

Traditional dental impression approach is not applicable to most of the oral and craniofacial trauma patients. Without a physical model, it is not easy to evaluate a patients fracture and occlusion, limiting the treatment process. Especially, the accuracy of the maxillofacial model for occlusion evaluation needs to meet strict clinical demands. Therefore, in this research, we attempted to use computed tomography (CT), without damaging the oral and craniofacial tissues of patients, together with image processing and Rapid Prototyping (RP) technique to obtain physical oral and maxillofacial models with high accuracy. Initially, a set of procedures of generating maxillofacial model was developed. CT images were segmented and converted to a CAD file by a commercial medical image processing software. RP technique was used to fabricate maxillofacial model. After comparison, the deviations were greater than clinical demands of less than 1 mm. After analyzing the sources of errors, issues of CT slice thickness, images threshold selection and editing, and RP fabrication were investigated to improve the accuracy. As a result, updated standard procedures were suggested to obtain RP maxillofacial models with higher accuracy. The improved average deviation can be reduced to 0.22 mm. The biological RP models with high accuracy generated in this research can be used to improve success rate and safety in a surgery, to reduce complications after the surgery, and to decrease the time and cost of treatment.
