A white light interferometery (WLI) method for investigating surface microstructure was introduced. Brief description of the principle of this method was provided. The surface structure of various samples, for example, a liner board paper, a pigment coated paper, a intaglio printed paper and a polymer laminated paper were tested and characterized with the WLI method. The data showed the WLI method provided very detailed information about surface topography, which were little affected by the surface condition such as color, opacity, roughness, etc. The data stitching mode of the WLI method could provide high spatial resolution over a large field-of-view, which made it possible to obtain the statistically valid results. Fast and high repeatability also made this method a promising way for investigating the surface micro-structure of paper products and prints.

In this paper, we present reusable quartz master fabricated by electron-beam lithography and dry etching process of quartz, and results of injection molding based on the reusable quartz master for the manufacturing of nano-scale information media. Since patterned structures of photoresist can be easily damaged by separation (demolding) process of nickel stamper and master, a master with photoresist cannot be reused in stamper fabrication process. In this work, we have made it possible of the repeated use of master by directly patterning on quart in nickel stamper fabrication process. We have designed and fabricated four different specimens including 100nm, 140nm 200nm and 400nm pit patterns. In addition, both intaglio and embossed carving patterns are fabricated for each specimen. In the preliminary test of injection molding, we have fabricated polycarbonate patterns with varying mold temperature. We have experimentally verified the fabrication process of the reusable quart master and possibility of quartz master as direct stamper.

In various industries, tactile recognition has been one of the important ways in displaying information because peoples like to touch and feel. Especially, how much the tactile information is efficiently recognizable is crucial for visually impaired persons in their daily lifes. However, existing design guidelines are insufficient to lead good tactile recognition. In this study, an experiment was performed to investigate proper tactile shapes (relievo / intaglio vs. filled / unfilled), sizes and depths for efficient tactile recognition. Moreover, this study scrutinized whether the recognition speed or error was varied depending on the type of displayed symbols (open vs. closed types) in tactile. The experimental results revealed that the 'relieve-filled' shape type was more rapidly recognizable than the other shapes, and the 'closed' type symbols (e.g., ${\square }$. ${\bigcirc}$) were more robustly recognizable than the 'open' type symbols (e.g, +, ^). Several design guidelines were presented based on the results. These guidelines can be applied to the design of tactile buttons in the devices that users should control them without visual attention, such as car steering wheels or MP3 players.

This article reviews the topic of how to identify and develop a removable partial denture (RPD) path of placement, and provides a literature review of the concept of the RPD path of placement, also known as the path of insertion. An optimal RPD path of placement, guided by mutually parallel guide planes, ensures that the RPD flanges fit intimately over edentulous ridge structures and that the framework fits intimately with guide plane surfaces, which prevents food collecting empty spaces between the intaglio surface of the framework and intraoral surfaces, and ensures that RPD clasps engage adequate numbers of tooth undercuts to ensure RPD retention. The article covers topics such as the causes of obstructions to RPD intra-oral seating, the causes of food collecting empty spaces that may exist around an RPD, and how to identify if a guide plane is parallel with the projected RPD path of placement. The article presents a method of using a surgical operating microscope, or high magnification (6-8x or greater) binocular surgical loupes telescopes, combined with co-axial illumination, to identify a preliminary path of placement for an arch. This preliminary path of placement concept may help to guide a dentist or a dental laboratory technician when surveying a master cast of the arch to develop an RPD path of placement, or in verifying that intra-oral contouring has aligned teeth surfaces optimally with the RPD path of placement. In dentistry, a well-fitting RPD reduces long-term periodontal or structural damage to abutment teeth.

For the improvement of letterpress printing paper quality, special fibers obtained from the sea were used by mixing with wood fibers. The sizes of the special fibers, which were from red algae in the sea, were 0.5-1 mm in length, and 3-7 ${\mu}m$ in width, respectively, and the fibers were supplied by Pegasus Research Inc. for the study. From the study, it was found that 10% addition of algae fibers greatly improved paper surface strength and internal bonding strength. The compressibility was estimated by utilizing 'Print-surf method' at high clamping pressure and with hard backing. Again, 10% addition of algae fibers greatly improved the compressibility of the paper. These results were expected that algae and wood fibers were distributed evenly through the sheet, and integrated one another to leave no empty space inside the paper.

The purpose of this study was to analyze the expressive characteristics of Chinese shadow puppetry costumes. Literature study and case analysis were conducted using books, research papers, and materials from the Xi'an shadow puppetry museum. Based on the Chinese traditional costumes, the shape characteristics are utilized with the intaglio and embossing techniques, and the complex and unnecessary details are omitted to express the costume image in a characteristic and simple manner. Second, colour was used according to the traditional Chinese symbolic colour concept, and the brighter the colour, the higher the role's status. The colour was also used to express identity and character. In addition, relatively vivid and highly saturated colours were used for the transparent effect of the shadow puppetry. Third, a role's status is indicated by the density and completeness of the patterns; the higher the role's status, the more complex and sophisticated the patterns, and the lower the status, the simpler the patterns or no patterns are used. Fourth, the faith for blessing expressed in the shadow puppetry is a representative folk auspicious culture. The repertoire of the shadow puppetry and the patterns on the costumes worn by the puppets, express the culture in an implicit way to symbolize the meaning of auspicious things.

이 연구는 사진 조명 기법과 디지털 기법을 이용한 사진 탁본을 통해 기존 탁본을 대체할 수 있는지 알아보는 것에 목적이 있다. 조명 기법은 전자플래시를 사용한 질감 묘사 이론에 근거했으며, 명문의 판독이 목적이므로 조명을 양 측면에서 조사하여 음각된 명문을 강조하였다. 촬영한 사진은 포토샵을 이용해 명문을 강조하는 방향으로 수정하였고 이 과정에서 지의류로 인해 비석에 생긴 얼룩을 약화시킬 수 있었다. 특히 비문 일부가 훼손 혹은 박락되어 명문이 희미한 경우에도 디지털 기법을 이용하면 어느 정도 판독의 가능성을 보여주었다. 또한, 기존 탁본으로는 할 수 없는 비석의 재질, 풍화상태, 박락 등에 대한 기록을 따로 하지 않아도 촬영과정에서 자연스럽게 기록이 되므로 문화재 연구와 보존, 복원 등에 도움을 줄 것으로 생각한다.

The objective of this case report is to introduce a simple technique for simultaneously taking a closed-mouth impression and functionally generated path (FGP) for a full coverage crown restoration. A monolithic zirconia crown was the restoration of choice. An alginate impression of the abutment tooth was taken to fabricate a custom-made closed-mouth impression tray covering the abutment tooth and the adjacent teeth. The tray had an FGP table and an abutment tray in cameo and intaglio surfaces, respectively. The impression was taken with silicone impression material after adjusting the abutment tray and inscribing the FGP using self-curing acrylic resins. Plaster casts were made from the impression, and a zirconia crown was fabricated. The crown was cemented to the abutment tooth with minimal adjustments. This simple technique resulted in a well-fitting crown that accounted for mandibular movements. Using the custom closed-mouth impression tray incorporating an FGP table simultaneously aids in fabricating an accurately fitting restoration that incorporates harmonious mandibular movements using a single impression capture.
