  • Digital dentistry is becoming a mainstream of dental practice. We are already used to intraoral scan, guided implant surgery, manufacture of prosthesis (CAD-CAM) in our daily practice; those are not sensational anymore. However, treatment planning with digital simulations is not spotlighted enough. In this report, a digital mockup was utilized to visualize the final goal of maxillary rehabilitation including all anterior and posterior teeth, and persuade a patient who wanted restoration of only anterior teeth. We will also discuss the use of digital mockup and its actual copy as the guide of altered vertical dimension through the clinical process.

  • Industrial innovation in Britain, during the eighteenth and nineteenth centuries, stimulated the introduction of the factory system and the migration of people from rural agricultural communities to urban industrial societies. The factory system brought elevated levels of economic growth to the purveyors of capitalism, but forced people to migrate into cities where working conditions in factories were, in general, harsh and brutal, and living conditions were cramped, overcrowded and unsanitary. Industrial developments, known collectively as the 'Industrial Revolution', were driven initially by the harnessing of water and steam power, and the widespread construction of rail, shipping and road networks. Parallel with these changes, came the development of purchasing 'middle class', consumers. Various technological ripples (or waves of innovative activity) continued (worldwide) up to the early-twenty-first century. Of recent note are innovations in digital technology, with associated developments, for example, in artificial intelligence, robotics, 3-D printing, materials technology, computing, energy storage, nano-technology, data storage, biotechnology, 'smart textiles' and the introduction of what has become known as 'e-commerce'. This paper identifies the more important early technological innovations, their influence on textile manufacture, distribution and consumption, and the changed role of the designer and craftsperson over the course of these technological ripples. The implications of non-ethical production, globalisation and so-called 'fast fashion' and non-sustainability of manufacture are examined, and the potential benefits and opportunities offered by new and developing forms of social media are considered. The message is that hand-crafted products are ethical, sustainable and durable.

  • This paper was analyzed the characteristics of piezoelectric inkjet print head using finite element method(FEM). It showed the bending node driving of piezoelectric and relation theory principle consider piezoelectric material characteristics and ink characteristics. From such result we were had the piezoelectric head design and manufacture. It got a this head characteristics through experiment, we confirmed that proper voltage control is possible to through ink drop control experiment of piezoelectric print head. This paper was obtained the suitable ink jetting characteristics that manufacture the control circuit and piezoelectric inkjet print head. This practice product was applied to improvement of PCB electric circuit pattern by etching resist ink that PCB manufactured to complex process over traditional 6 stages can be simpled to 1 stage by inkjet printing technology.

  • This study developed the conductivity pattern of solid surface using laser direct pattern and compound polymer material technology. For development direct patterning system of solid surface, we used the laser power stabilizer, the dynamic focusing, 3D scanner S/W and the auto aligning techniques. Also For conductivity pattern, we are developed compound polymer material with additive by electro-less plating. These technologies are already used commercially. However operation and control integrated system for direct patterning of solid surface are not yet developed. The objective of this paper is to introduce the laser direct structuring for simple process improvement instead complex PCB process, and develop the operating stability and integration system. Also we implemented new application of laser direct structuring through sample manufacture.

  • This study aim to suggest how alter the korean traditional image design for umbrellas by sublimation transfer digital textile printing. Umbrellas are highly depend on design and made from polyester fiber which is proper item to utilize sublimation transfer digital textile printing. Sublimation transfer digital textile printing system can use computer system to create the delicate high dense images and one full layout through the hole umbrella. It can create distinctive style of design compare with former screen printing umbrella design. As a result of this study, Korean traditional images were adopted and recreated for umbrellas as the modern practical item. 7 of umbrella designs were developed and sample umbrellas could be produced in short period comparing with screen printing process. Through this study, as green printing process, sublimation transfer digital textile printing will be more applied to manufacture high quality textile products along with design development, thus it is expected as an alternative plan to leads growth of umbrella industries.

  • Digital manufacturing(DM) is the ability to describe every aspect of the design-to-manufacture process digitally-using tools that include digital design, CAD, office documents, PLM(Product Life-cycle Management) systems, analysis software, simulation, CAM software and so on. The major automotive companies are already deeply invested in DM with almost every process being digital rather than paper-based. But it has taken a long time for the digital process to mature into something usable and there have been some major barriers that have prevented from the DM becoming a reality. Thus many companies hesitate to make a decision of implementing the DM. This paper deals with a study investigating which factors are important for implementing the DM to industries successfully. The extended technology acceptance model (ETAM) is used as the relation model of cause and effect. The quality of hardware, the quality of software, the range of collaboration among companies and the preference of the user are defined as the external factors. Interview method is used for gathering input data, and the results are analyzed with SPSS. The results indicate that four external factors are effective on the successful implementation of DM, and the perceived usefulness is most important.

  • The purpose of this study is to demonstrate the stage costumes realized by digital clothing ; how realistic and accurate representation of empirical testing and in the consultation process for the production stage costumes, determine whether digital clothing has value that can be substituted for the stage costume. This study researched the stage costume manufacture, Isabel's costume of the musical 'Christmas Carol', process by using the 3-D clothing simulation technology : DC Suite. The results of this study is as following. They share many similarities between the stage costumes and digital clothing. It is possible that digital clothing takes a role as a substitute for stage costumes in the production process of the clothing samples. The clothing production system, including stage costumes, by digital clothing costs and lead time can be saved by innovative. Also the result can be saved without restriction, and this system can exert its effect in a very efficient way to incorporation of foreign producers and production system.

  • The purpose of this paper is to develop an automatic measuring system based on the digital image processing which can be applied to the in-process measurment of the characteristics of the thin thickness. The derivative operators is used for edge detection in gray level image. This concept can be easily illustrated with the aid of object shows an image of a simple light object on a dark background, the gray level profile along a horizontal scan line of the image, and the first and second derivatives of the profile. The first derivative of an edge modeled in this manner is 0 in all regions of constant gray level, and assumes a constant value during a gray level transition. The experimental results indicate that the developed automatic inspection system can be applied in real situation.
