The human sense of touch provides us with an important source of information about our surroundings. Because of its unique position at interface between our bodies and the out world, touch sensation supplies sensory data which helps us manipulate and recognize objects and warn of harmful situation. But tactile sensation was recognized less important than visual sense and auditory sense but it plays an important immersing role in virtual reality and computer game. Tactile sensation can be used to influence to objects according to power and supplied sensory feedback to the player in a virtual environment. This paper investigated the characteristics of tactile sensation of human being and proposed method of sturdy using force sensing sensor, simple force modeling and data structure form for virtual reality and computer game. As a result, force distribution, depth, center point can be calculated using sensor output and this information is very effective to specific position for actions and reactions. This study can used as basic information for tactile sensation and it's application in computer game and virtual realty.

A semiotic approach to modern visual arts has emerged since French post-structuralism was introduced to Anglo -American academics by "deconstruction" or "postmodernism." It views a work of art as a sign, which is its methodical assumption ana at the same time makes its application more accessible In the milieu of modern visual arts'effort to be intimate to with general audience, modern art photography is now faced with the request to be a familar and universal domain instead of being left only in photo books as artistic and academic achievements More specifically, various photo images 1mm such visual media as newspapers TVs, and computer graphics to such megaexhibitions as "Gwangju Biennale," "Media City Seoul," and "Pusan International Art Festival," are main objects of s030y. A coherent and scientific analysis of visual semitotics is still on the way; however, it is an urgent task how to read and interpret a photo image with multiple meanings This study argues that visual semiotics can be a powerful tool to enhance the understanding of art photography. After all, semiotics is a product of age; we live in the age of legibility, that is, of reading the work of art well as the social events and phenomena.rk of art well as the social events and phenomena.

After the scientific development of human history, numerous images have been developed and expanded in digital media as a communication tools. Image digital media make communication closer between sender and receptor. The image digital media which has been developed with the change of technology and media transformation have shortened visual information transportation and the time as well by combining the sense of visual and audio. Motion graphic field has been emerged as the type of image digital media development. The development of motion graphic make possible for the expressive effect and dynamic image technique which is impossible by the existing media type. Especially, it is applied to various field such as the title of movie, TV program, and advertise or music video etc. These image expression techniques are stimulating acceptor's emotion to take a role of emotion communication function also. This study aims to find the characteristics motion graphic of which how influence as an effective communication tool as important role to the receptors, and the examine the effect and application of motion graphic to the receptors as a emotion communication tool by case study.

In this paper, the lumped element model parameter estimation method and its implemented estimation software for fabricated floating mass transducers of IMEHDs have been presented so that the estimated parameter values could be compared with the designed ones and applied to predict the output performance when the transducers were implanted into human ears. The presented method is based on the sequential quadratic programming (SQP) for estimating parameters in the transducer's lumped model and has been implemented by the use of LabVIEW graphical language. Using the implemented estimation software, the accuracy of parameter estimation has been verified and our implemented estimation method has been evaluated by the comparison of the estimated transducer parameter values with the designed ones for a practically fabricated floating mass transducer for IMEHDs.

It is urgent to have learning support for children with learning disability according to the survey made by the government educational organization. To this end, we developed a learning support system for children with learning disability. First, the system diagnoses the children with learning disability using a decision tree based on the pre-test results. Secondly, it supports for children with learning disability one of audio-, vision- and tactility-oriented learning types according to the results from the psychological learning style test. Thirdly, one-to-one study is supported for failed students at the achievement test. For the evaluation of the system, the children with disability were divided into an experimental group and a control group and the educational achievement was evaluated. We found that 10% on the average was improved in case that learning was made after the psychological test for learning styles.

Inhibition of xanthine oxidase by seaweed extracts obtained from Undaria pinnatifida, Ecklonia stolonifera, Ecklonia cava, Laminaria japonica, Sargassum, Codiumfragile, Enteromorpha compressa and Porphyra tenera were investigated. Extracts of E. stolonifera and E. mua remarkably inhibited xanthine oxidase activity compared to those of other seaweed. The xanthine oxidase inhibitory activity of E. cava was higher than that of E. stolonifera. Diethyl ether extract from E. cava was more effective in the inhibition of xanthine oxidase than other solvent extracts. Two xanthine oxidase inhibitors(A-1 and A-2) from diethyl ether extract were isolated and purified by silica gel column chromatography, thin layer chromatography and high performance liquid chromatography. Xanthine oxidase inhibitory activities of these compounds were 27.8 and 48.1% per 0.4mg, respectively. The active compound A-2 had absorption peak at 420nm, 456nm and 467nm, which can be considered as siphonaxanthine.

In this paper, a new matrix decoding system using vector based Virtual Source Location Information (VSLI) is proposed as an alternative to the conventional Dolby Pro logic II/IIx system for reconstructing multi-channel output signals from matrix encoded two channel signals, Lt/Rt. This new matrix decoding system is composed of passive decoding part and active part. The passive part makes crude multi-channel signals using linear combination of the two encoded signals(Lt/Rt) and the active part enhances each channel regarding to the virtual source which is emergent in each inter channel. Since the virtual sources are related to the perceptual sound images in virtual sound field, the reconstructed multi-channel sound results in good dynamic perception and stable image localization. Moreover, the good channel separation is maintained with nonlinear trigonometric enhancing function.
