Sharp has developed industry's largest high-definition LC TV, Aquos LC-45GDI. In this paper, we discuss its 10-bit signal processing as one important enabler of its excellent picture quality. Utilizing 10 bits signal processing, in combination with full-spec High-Definition panel and "Intelligent Environment Illumination Sensor", we have succeeded to realize a beautiful gigantic LC TV.

In this parer, a high quality mesh generation method by using interval arithmetic is proposed. In the proposed method, the variance of a tangent vector at the point is considered by the automatic differentiation. From the variance, sampling points on the surface are judged whether it is adequate or not, which is calculated by the interval arithmetic. Then Delaunay triangulation is performed to the obtained sampling points, and a set of meshes is generated. The proposed method is hard to overlook the local variation of surfaces.

In this paper, we propose a non-blind watermarking method that embeds a pseudo-random sequence (watermarks) into wavelet DC components. The DC area is not suitable for embedding because of severe visual degradation. We overcome the degradation problem by embedding watermarks into visually insensitive locations. We compare our experimental results with respect to JPEG compression with Cox’s popular correlation-based method. We also compare the robustness of our technique with other methods registered in CheckMark. This study reveals that the proposed method simultaneously provides good fidelity in quality as well as robustness against external attacks.

There have been intensive attempts to establish reliable methods far in vitro production (IVP) methods for of porcine embryos. Although a great deal of progress has been made, our current IVP systems still need to be improved. In this review, we focused on studies about in vitro maturation and fertilization (IVM-IVF) of porcine oocytes and their in vitro culture (IVC), especially on an excellent piglets production system using modified IVP system producing porcine blastocysts with high Quality.

This paper describes synthesis of a complex R$^{i}$ CR filter with a finite transmission zero except zero frequency. First, a new kernel function is proposed. Secondly, how to determine the element values included in the R$^{i}$ CR filter is described. A fifth-order R$^{i}$ CR filter is designed. Finally, the sensitivity property of the proposed filter is evaluated through computer simulation.

3M has developed a Precision Replication Process for the production of PDP Barrier Ribs and other display devices. This process, is fast, clean and capable of producing very high resolution (FHD and beyond), high aperture ratio and fine cell structures. Recent advances in materials and process features will be discussed.

니켈기 전열관 소재에서 결정립계의 misorientation을 분석하였다. 일반적으로 대부분의 결정립계에서 석출물을 관찰 할 수 있지만 쌍정과 만나게 되면서 석출물의 분포가 갑작스럽게 변하는 것을 관찰 할 수 있다. 이러한 현상은 결정립계의 구조와 에너지에 관련되는 결정립계의 misorientation 특성에 갑작스런 변화가 생겨나기 때문이라. 이러한 결정립계의 misorientation 특성은 T.E.M (Transmission Electro Microscope)에서 얻은 각 결정립의 Kikuchi pattern을 이용하여 분석하었다. 석출물을 갖는 결정립계들은 random high angle 결정립계이고 석출물이 존재하지않는 결정립계들은 특정한 C.S.L ( Coincidence Site Lattice) 결정립계이었다.

As one of the serial studies on the taxonomy of Conthocamptus mirabilis species group in South Korea, C. semicirculus Kikuchi, widely distributed in the southern part of the Far East, and C. coreensis n. sp. from the middle west of South Korea are recorded. Intraspecific variability of some important characters like outer caudal setae and the spinous process of male leg 3 exopod was examined in Korean population of C. semicirculus. Canthocamptus coreensis n. sp. possesses the plesiomorphic characters of the round and narrow hyaline membrane of anal operculum and lacking the sexual reverse transformation in female caudal rami, while it also evolves the apomorphic ones of the modified outer apical setae of male leg 4 exopod and the spinous process of male leg 3 exopod. A key to the five species of the species group known from Korea is prepared.
