This paper proposes a new equation to calculate computer-generated hologram (CGH) in a high speed and its cell-based VLSI (veri large scale integrated circuit) architecture. After finding the calculational regularity in the horizontal or vertical direction from the basic CGH equation, we induce the new equation to calculate the horizontal or vertical hologram pixel values in parallel. We also propose the architecture of the CGH cell consisting of a initial parameter calculator and update-phase calculator(s) on the basis of the equation and implement them in hardware. Also we show a hardware architecture to parallelize the calculation in the horizontal direction by extending CGH. In the experiments we analyze the used hardware resources. These analyses makes it possible to select the amount of hardware to the precision of the results. Here, for the CGH kernel and the structure of the processor, we used the platform from our previous works.

We introduce an implementation of plug-ins on PLUTO. These plug-ins discriminate inflammatory nodules from other types of nodules in chest X-ray CT images. The PLUTO is a common platform for computer-aided diagnosis systems on Microsoft Windows series and it is easy to add new functions as plug-ins. We coded two plug-ins. One of the them calculates features based on medical knowledge. The other plug-in calculates parameters to classify the type of nodules, and it also classifies nodules into inflammatory nodules and others using SVM. These plug-ins are coded using MIST library which is produced at Nagoya University, Japan. In our previous study, the MIST library was parallelized, so that we can utilize a number of CPUs to calculate features and SVM learning/classifying depending on the amount of computation. Using these plug-ins, it became easy to extract features to discriminate inflammatory nodules from other types of nodules and to change parameters for feature extraction and SVM learning/classifying with GUI interface. The accuracy of the classifying result is 100% with 78 solid nodules which contains 43 inflammatory nodules and 35 other type of nodules.

The purpose of this study is to understand what the Glam Style is, focus on the movie "Velvet Goldmine". The Glam Style is refered early 1970s Glam rockers' costume, typified by silver lurex, corksoled platform, men in make-up, personified, for example, by David Bowie, Marc Bolan, New York Dolls, Roxy Music and Iggy Pop. To approach the Glam Style comprehensively, I have divided the formative background of Glam Style into the improvement technology, the advent of the young generation and the diffusion of mass media, the rock music fever and influence on Pop art. Following is the result of analyzing of the character in the movie. First, Brian Slade has the flamboyant transsexual image by skin-tight space suit, glitter pants, lurex, satin and sequined stretch fabrics, vivid color, gauze make-up, feather boa. Second, Curt Wild expresses the outrageous sexual image by black leather jacket, emphasized black eyes make-up. Third, Mandy Slade appears the exaggerated and frivolous image by gold leopard patterned one piece, fur coat, ornamented with beads, tropical make-up, spangles and the costume jewelry. Forth, Auther Stuart has the complex image by black leather jacket, velvet jacket, skin-tight bold shirt, glitter pants, glitter make-up, silk scarf, cherry-red sunglasses. The characteristics meaning of Glam Style implied in this formative characteristic could be presented as the experimental expression of androgynous, the hordes of outrageous alien and kitsch parody.

In recent years, social media that has emerged with the development of network technology has changed the channels of information dissemination. The social Q&A community is a platform for knowledge-sharing activities in a question-and-answer manner based on Web 2.0. In knowledge-sharing activities, valuable new knowledge continues to be produced and will surely bring great benefits to individuals or businesses. In the social Q&A community, the user's subjective factors play a crucial role in influencing the user's continued use and participation in knowledge-sharing activities. In order for users to actively participate in knowledge-sharing activities in the community, it needs to grasp their subjective ideas. This study explores the issue of sharing knowledge by users of the social Q&A community "Zhihu", or how to drive community revitalization efforts from these. The three factors self-efficacy, self-development motivation, and social comparison tendencies were derived, and identify their relationship with knowledge-sharing activities and community-boosting efforts through empirical analysis. In addition, the influence of knowledge acquisition on knowledge provision was investigated through sense of reciprocity. Implications of the study findings and the future research directions were also discussed.
