As the quality of life increases and the aesthetic value of the product is emphasized, it tend to consider the sensitivity of consumers in designing goods. The importance of storytelling is becoming more prominent as the purchasing factor of products shifted from the center of the product to emotional of products. In this paper, the purpose of developing emotional marketing craft design using storytelling is to understand the storytelling concept and analyze the case of craft design using storytelling. Craft is an easy-to-value or aesthetic value of the goods in the fields of design, diversity and originality can be pursued and has unlimited potential. Now, in addition to the semantic value of expressive values with a consumer sensibility needs requires the development of this research craft crafts design industry has established itself as a high value-added industry could do more to take advantage of the Foundation.

Modular reconfigurable robots with physical docking capability easily adapt to a new environment and many studies are necessary for the modular robots. In this paper, we propose a vision-based fuzzy autonomous docking controller for the modular docking robots. A modular docking robot platform which performs real-time image processing is designed and color-based object recognition method is implemented on the embedded system. The docking robot can navigate to a subgoal near a target robot while avoiding obstacles. Both a fuzzy obstacle avoidance controller and a fuzzy navigation controller for subgoal tracking are designed. We propose an autonomous docking controller using the fuzzy obstacle avoidance and navigation controllers, absolute distance information and direction informations of robots from PSD sensors and a compass sensor. We verify the proposed docking control method by docking experiments of the developed modular robots in the various environments with different distances and directions between robots.

This paper is a study on image noise reduction of modified sigma filter by image decomposition using directivity. Conventional sigma filter has been shown to be a good solution both in terms of filtering accuracy and computational complexity. However, the sigma filter does not preserve well small edges especially for high level of additive noise. In this paper, we propose here a new method using a modified sigma filter. In our proposed method the input image is first decomposed in two components that have features of horizontal, vertical and diagonal direction. Then, two components are applied HPF and LPF. By applying a conventional sigma filter separately on each of them, the output image is reconstructed from the filtered components. Added noise is removed and our proposed method preserves the edges from the image. Comparative results from experiments show that the proposed algorithm achieves higher gains, on average, 2.6 dB PSNR than the sigma filter and 0.5 dB PSNR than the modified sigma filter. When relatively high levels of noise added, the proposed algorithm shows better performance than two conventional filters.

Parody, which is the device of humorous Postmodernism artists, has been from the comic immitation with the popular and well-known object. It's expressive techniques are very various such as similarity, transformation, exaggeration, irony, parados, inversion etc. and also it can be used another techniques of designer's will and ability based. Parody's effect consists of satire, mockery, scorn, ridicule, unexpectedness, defamiliarize, playfulness, wit, respect, esteem, wonder and so on of the original. So parody has a critical distance from the original, whichis the object of immitation. Ultimately, the expression of parody can be as extensive as from an ironic and funny inversion still containing the respect for the original to a contemptuous mockery. Nowadays Parodists have a tendency to use parody actively in order to criticize the real world or to meet the past with ironic recontextualize. And parody include the specific characters of postmodern design. So parody is widely known as a effective forms of expression in now-a-days our environment surrounded with the postmodern esthetics, and it's request will be increased rapidly. As a part of art, parody is apt to use widely in Fashion too. And from a historical standpoint it is to reconstitute the past with a critical eye and finally to become a new technique to create the new Fashion style with an intention of extension of design area.

This paper describes an efficient hardware implementation of lightweight block cipher algorithm CLEFIA. The CLEFIA crypto-processor supports for three master key lengths of 128/192/256-bit, and it is based on the modified generalized Feistel network (GFN). To minimize hardware complexity, a unified processing unit with 8 bits data-path is designed for implementing GFN that computes intermediate keys to be used in round key scheduling, as well as carries out round transformation. The GFN block in our design is reconfigured not only for performing 4-branch GFN used for round transformation and intermediate round key generation of 128-bit, but also for performing 8-branch GFN used for intermediate round key generation of 256-bit. The CLEFIA crypto-processor designed in Verilog HDL was verified by using Virtex5 XC5VSX50T FPGA device. The estimated throughput is 81.5 ~ 60 Mbps with 112 MHz clock frequency.

This study intended to examine the nature of image which uses the network as the medium in the context of 'post-internet art' and categorize and analyze the cases of applications within art images. In the post-internet art which embraces the background of Web 2.0 and extended digital and network environment, image is transformed and re-mediated into various formats beyond fixed forms. Hito Steyerl defined the image, copied, downloaded, and reedited digitally in low quality as 'poor image.' Young artists, the digital native generation, capture and re-contextualize the changed network environment and depict it in various images. In this context, the application of image in post-internet art can be categorized and analyzed into the 'Image Collected as Material' produced by collecting and recomposing images found in social media, operating system, and website, 'Image Processed through Work' which is newly processed and re-contextualized by using editing programs, and 'Combined Digital-Reality Image' which represents the section of the digital society as the film and image that combine virtuality and reality.

In this study, multilayered rings with a large outer diameter have been developed using a hot ring rolling process. The ring rolling process has been analyzed by rigid plastic finite element analyses (FEA) using the AFDEX2D and AFDEX3D/HEXA/RING simulators, where the finite element meshes received severe plastic deformation are remeshed into a fine mesh-size using a dual-mesh system. According to the simulated results, the design variables of the multilayered rings were determined and real tests were conducted to check the validity of the simulation results. By adopting the hot ring rolling process, the input weight of raw materials was reduced by 40% against the conventional hot forging process and that the recovery rate was increased by 24%. The measurement of the averaged roundness was satisfied within 0.5 mm for both the inner and outer diameters. Moreover, the hot ring rolling processes yielded 1.49 Cpk for the outer-diameter and 0.84 Cpk 0.84 for the inner-diameter.

In a process of insect foot recognition, footprint segments as basic areas for recognition need to be extracted from scanned insect footprints and appropriate features should be found from the footprint segments in order to discriminate kinds of insects, because the characteristics of the features are important to classify insects. In this paper, we propose methods for automatic footprint segmentation and feature extraction. We use a Trace transform method in order to find out appropriate features from the extracted segments by the above methods. The Trace transform method builds a new type of data structure from the segmented images by functions using parallel trace lines and the new type of data structure has characteristics invariant to translation, rotation and reflection of images. This data structure is converted to Triple features by Diametric and Circus functions, and the Triple features are used for discriminating patterns of insect footprints. In this paper, we show that the Triple features found by the proposed methods are enough distinguishable and appropriate for classifying kinds of insects.

This essay attempts a historical examination of educational function of the novel. It pays attention to the eighteenth century sentimentalism, and its historical vicissitudes up to early twenties century. The eighteenth century is the period in which debates on the nature of emotion and its moral and aesthetic role have passionately taken place and the modern paradigm of thought on affect has been formed. This is why "affect revival phenomenon" in the late twenties century goes back to this period. This essay finds in Adam Smith the most sophisticated arguments on sympathy in their relation to the development of the novel; it examines the relationship of Smith's argument with modern novel in the tradition of sentimentalism, and its revision in modernist novel. Through this examination, it discusses how cognitive and non-cognitive approaches, the two representative positions in contemporary thinking on emotion/affect, have revised and transformed the eighteenth century sentimentalism.

Based on Deleuze's body aesthetics and from the perspective of 'deterritoraliazation', this study makes an in-depth discussion on the modern fashion design modeling by four visual characteristics: hysteria, visualization, body segmentation and becoming animals. First, hysteria embodies the strong visual effect brought by the deformation and exaggeration of clothing. Second, visualization in fashion shows the elimination or ambiguity of faces, representing the weakening of identity and the prominence of clothing and body. Third, body segmentation represents the deconstruction and reorganization of clothing, and a new way of thinking, as well. Fourth, becoming-animals are manifested in the physical mutation caused by the heterogeneous connection between humans and animals, which brings about the possibility of rethinking the body.
