  • In this work, soft sensor based on image anlaysis is proposed for quantitatively estimating the visual appearance of manufactured products and is applied to quality monitoring. The methodology consists of three steps; (1) textural feature extraction from product images using wavelet transform, (2) numerical estimation of the product appearance through projection of the textural features on subspace, and (3) use of latent variables of textural features (i.e., numerical estimates of product appearance). The focus of this approach is on the consistent and quantitative estimation of continuous variations in visual appearance rather than on classification into discrete classes. This approach is illustrated through the application to the estimation and monitoring of the appearance of engineered stone countertops.

  • This paper proposes 3D graphics accelerator, especially rendering unit, for portable devices. The existing 3D architecture is not suitable for portable devices because of its huge size. To reduce the size, we use iterative architecture and fixed-point calculation. In this paper, we suggest the format of fixed-point comparing with the result images, and some special technique to control. Finally, it is implemented with FPGA and 0.25um ASIC technology respectively. The ASIC chip can execute 47.88M pixels per second. The size of ASIC chip is 4.9287mm*4.9847mm and the power consumption is 263.7mW with 50MHz operation frequency.

  • This study was conducted to develop a optimal composite recipe of a functional cookie including Red Ginseng powder and having the high preference to all age groups. Wheat flour was partially substituted by Red Ginseng powder to reduce the content of wheat flour. The sensory optimal composite recipe was produced by making iced cookies, with 5 levels of Red Ginseng $powder(X_1),\;sugar(X_2),\;butter(X_3)$, respectively, by C.C.D(Central Composite Design) and by conducting the sensory evaluation and the instrumental analysis by Response Surface Methodology(RSM). The results of sensory evaluation showed very significant values in color, appearance, texture, overall quality(p<0.05), flavor(p<0.01) and those of instrumental analysis showed significant values in lightness, redness(p<0.05), spread ratio, hardness(p<0.01). As a result, sensory optimal ratio of Red Ginseng cookie was calculated at Red Ginseng powder 25.4 g, sugar 147.1 g, butter 153.4 g.

  • MPEG-4 visual conformance standard specifies methods to verify whether bitstreams and decoders meet the requirements at the specified profile and level. The test of decoders can be divided into two parts: the static test and the dynamic test. The static test can be performed by examining the decoder output with that of a reference decoder. This paper proposes design methods of test bitstreams for static test of texture decoding, and shows the test results.

  • The bent wood technique has been used for making the bow, the musical instruments and the wagon wheel, The Winsor chair of England in 1730's was the first Lfurniture product by using this method. This method was spread out by Michael Thonet in Austria after the Industrial Evolution. Early making technique of Winsor chair was relatively easy, but Michael Thonet's bent chair was mass produced by the machine and launched the revolution in the industrial furniture. 20th-Century European furniture designers applied the method of layering and forming plywood to bent chairs, enhanced the function and conformability. The bent chair had a big impact on modern chair design. The bent chair has the formative beauty and convenience from the character of softness and colors of wooden materials and has been developed variously by furniture designers. This study is a new approach to use Dyed-Gathered Wood with various colors and patterns as a material of the bend wood. First, bent wood with the Dyed-Gathered Wood enhances a close texture of wooden material textures instead of coating the surface. Second, flexibility of the bent wood with the Dyed-Gathered Wood enables wood bending techniques. Lastly, the Dyed-Gathered Wood is made with relatively cheap woods, replaces expensive imported woods which cause product price rise. This method enables a material cost saving and a stable supply of material.

  • Estimations of porosity and bulk density, particle size analysis of soli samples, tracer test and slug test were performed in a petroleum contaminated area of Kangwon for understanding characteristics of the aquifer. Porosities of the samples were estimated 0.158~0.257, and bulk densities were estimated as $1.73\sim2.10\;g/cm^3$. Majority proportion of the soil samples was 0.5~1.0 mm size. In the soil texture triangle, all samples were distributed at sand area. Uniformity coefficients were estimated as 7.71~10.39, and thus all samples were poorly-sorted. In the tracer test, Darcy velocity was estimated to $4.8\times10^{-6}$ cm/day, effective porosity was 0.175, and longitudinal dispersivity was 0.1 m. According to the slug test, hydraulic conductivities of the test wells were estimated as $2.243\times10^{-2}\sim1.634\times10^{-2}$ cm/sec. These hydrogeologic parameters can be used for efficient remediation design of the petroleum contaminated area.

  • Since its introduction to the dentistry, the CAD/CAM technology has been used over fifteen years. The application of CAD/CAM started from coping fabrication, expanded to the posterior full crown, and anterior restoration manufacture has also become widespread recently. While the development of machine was rapid, the advance of zirconia block was the fastest. Although some differences exist among individuals, the various natural tooth color can be expressed through the zirconia coloring itself without porcelain build up. And the texture characteristics can be reproduced just by CAD design. In this article, the development history of digital dentistry was summarized.

  • To identify optimized thermal properties of mold brassiere cup for improved thermal comfort during summer, we compared the thermal resistance and the water vapor permeability of Polyurethane (PU) foam, 3D spacer fabric and the two combined materials of the PU foam and the 3D spacer fabric. Four experimental mold brassieres were made of the materials for wearing test. Six women in their twenties evaluated the wearing sensation in the hot and humid environment. The changes in microclimate temperature and humidity while wearing test brassiere cups were measured. Results indicate that thermal resistance increased as more PU foam were combined, while the water vapor permeability was higher as the content of the 3D spacer fabric increased at thickness of 18mm and over. However, in the wear test, the PU foam brassiere was the most preferred in all ambient conditions due to its soft, flexible and smooth texture, despite its high thermal resistance and low water vapor permeability. This indicates that the textures of mold foams are more dominant properties than thermal properties for mold foams in determining the wear comfort of mold brassieres.
