With the help of screenshots, human and nonhuman actors alike document their professional and leisure encounters with screen-based technologies. In this article, I investigate how and why screenshots have come to be understood as faithful visual records of digital culture. By tracing screenshot’s origins to photographic techniques used for capturing medical imaging, oscillograms, and first applications of computer-aided design, I show a lineage of a straightforward mode of representation built on the assumptions of indexicality and iconic resemblance. However, this initially mechanical act of image reproduction has given rise to transformative practices of promotional and artistic screenshots (represented in this article by in-game photography), which subvert the conventions of accurate representation. By contrasting these visual phenomena, I argue for the redefinition of screenshot and show the need for critical literacy of screenshot-based images.

The treatment of auricle defect can be by surgical or prosthetic ear rehabilitation depending on the condition. Current practice by surgeon for prosthetic ear rehabilitation require patient to go for osseointegrated craniofacial implant surgery for retention of the prosthetic ear. Impression technique play a vital role in accurate reproduction of affected and unaffected ears, orientation of the ear during wax try in and fabrication of ear prostheses. Traditionally, the wax pattern was created from the impression taken from patient and the final prosthesis is processed with silicone material. This conventional method has always been time consuming, massive work and caused discomfort to patient. Moreover the accuracy of the final prosthetic sometimes was not satisfied. Improvement in medical imaging technology whereby data from computerized tomography (CT) in 2D format can be converting to 3 dimensional images gave tremendous view for surgeon to visualize the result. A new and impressive advance in the development of additive manufacturing technology is now being able to be applied in medical field. The widespread use of computer-aided design (CAD) combine with computer aided manufacturing (CAM) produced the momentum and desire to translate the 3-D images into physical models. Studies and research have indicated the viability of using medical imaging technology, computer aided design (CAD) and additive manufacturing techniques in prosthetics. This paper proposed a novel method of fabricating the prosthetic ear applying mirror image technique to reconstruct the missing ear, and then fabricate the 3D model of the prosthetic ear using Stereolitography (SLA) technology that will become the master mold to produce the final prosthetic ear. This method eliminates the traditional wax pattern procedure. A clinical study is done onto a patient in HUSM and comparison is made between traditional method vs new approach using computer aided technology. Result showed that there is significant different between traditional and new approach design. The new method also shows time reduction during design and fabrication stage.
