  • A conservative treatment approach to temporomandibular disorder (TMD) is recommended as the first line of management, usually with a stabilization splint. Recently, computer-aided design/computer-aided manufacturing and three-dimensional printer has been widely used in the dentistry since several years ago. The authors apply digital dentistry in oral medicine fields to make stabilization splint for TMD treatment.

  • Three dimensional quantitative structure-activity relationship studies for a series of isatin derivatives as a nonpeptidyl caspase-3 enzyme inhibitor were investigated using comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). The first approach of non-peptidyl small molecules by 3D QSAR may be useful in guiding further development of potent caspase-3 inhibitors.

  • Both combinatorial and parametric optimization are used in computer-aided design(CAD). The most commonly occuring parametric optimization problems in engineering design such as design of control systems, design of electric circuits are usually expressed either as differentiable or as nondifferentiable semi-infinite programming(SIP) problems. In this paper we express algorithms for a class of computer-aided design problems arising in control systems.

  • The purpose of this study was to research about Dobby weave design using Computer-Aided Weaving System. For performing this design study, first, it was researched the characteristics of the classified woven fabrics, weaving processing, structure of Dobby loom, and Computer-Aided Dobby Weaving system theoretically. To develop Dobby woven design, Patternland Weave Simulator(U.S.A) for computer weave system was used. Among the developed Dobby woven designs by computer weaving system, mainly three of them were selected and woven into Dobby loom. To see the visual image of the fabric end-use, some of the scanned Dobby fabrics were simulated to the three-dimensional virtual images by Alias CAD system. The result of this study can be summarized as follows. Before the step of weaving Dobby fabrics on the woven design works, Computer-Aided Weaving system can be done very easily to apply the design step of Dobby woven fabrics, specially in case of the complicated woven structure. Also the usage of the simulation CAD system in visual image of the final products, ultimately can be saved cost and developed the higher value-added goods in more response to consumer demands.

  • Even though a conventional metal ceramic restoration is widely in use, its laboratory procedure is still technique-sensitive, complex, and time-consuming. A ceramic-pressed-to-metal restoration (PTM) can be a reliable alternative. However, simplified laboratory procedure for a PTM is still necessary. The article is to propose a technique that reduces time and effort to fabricate a PTM with the aid of computer-aided design, computer-aided manufacturing and selective laser sintering technologies.
