Digital media technology has power of influence as extended in not only science and technology but also our society and culture. These phenomenon is explained as 'digital convergence'. Edmond Couchot argue the term 'hybridization'. Yvonne Spielmann and Jay David Bolter also argue that digital hybrid artworks across and integrates a diverse range of modes of representation, such as image, text, sound, space and bodily modes of expression. They must also address communicative interaction in the convergence of real and virtual spaces. In this paper, I noticed mixed reality environment which is seen as the form of hybrid between real and virtual object. And I discuss about this phenomenon as the study of interdisciplinary between art and science.

In this paper we present a projection mapping system onto human's moving hand by a projector as information delivery media and Kinect to recognize hand motion. Most traditional projection mapping techniques project a variety of images onto stationary objects, however, our system provides new user experience by projecting images onto the center of the moving palm. We explain development process of the system, and production of content as applications on our system. We propose hardware organization and development process of open software architecture based on object oriented programming approach. For stable image projection, we describe a device calibration method between the projector and Kinect in three dimensional space, and a denoising technique to minimize artifacts from Kinect coordinates vibration and unstable hand tremor.

In this paper, multiple pedestrians tracking system using Histogram of Oriented Gradient and occlusion detection is proposed. The proposed system is applicable to Intelligent Surveillance System. First, we detect pedestrian in a image sequence using pedestrian's feature. To get pedestrian's feature, we make block-histogram using gradient's direction histogram based on HOG(Histogram of Oriented Gradient), after that a pedestrian region is classified by using Linear-SVM(Support Vector Machine) training. Next, moving objects are tracked by using position information of the classified pedestrians. And we create motion trajectory descriptor which is used for content based event retrieval. The experimental results show that the proposed method is more fast, accurate and effective than conventional methods.

There are many technically difficult issues in searching multimedia data such as image, video and audio because they are massive and more complex than simple text-based data. As a method of searching multimedia data, a similarity retrieval has been studied to retrieve automatically basic features of multimedia data and to make a search among data with retrieved features because exact match is not adaptable to a matrix of features of multimedia. In this paper, data clustering and its indexing are proposed as a speedy similarity-retrieval method of multimedia data. This approach clusters similar images on adjacent disk cylinders and then builds Indexes to access the clusters. To minimize the search cost, the hashing is adapted to index cluster. In addition, to reduce I/O time, the proposed searching takes just one I/O to look up the location of the cluster containing similar object and one sequential file I/O to read in this cluster. The proposed schema solves the problem of multi-dimension by using clustering and its indexing and has higher search efficiency than the content-based image retrieval that uses only clustering or indexing structure.

The development of material separation technique for waste plastic recycling are the necessary situation restricted by law the reclamation and incineration of waste plastic after 2004, with enforcement of EPR (Extended Producer Responsibility) system. As the this study is the research on the development of electrostatic separation techniques for recycling of life circles waste plastic by development of charging material and charger, the separation efficiency can be improved. Therefore, we developed the charger and electrostatic separator to increase charging efficiency and material separation per object plastics, rising these equipments, we removed PVC up to $99\%$ from two kinds of mixed plastics. And in case of restricting PVC content such as PET, we developed the separation technique that can remove PVC up to $99.99\%$ from PET with PET recovery about $80\%$. Also, as we separated over $98\%$ for three kinds of mixed plastics, and then established material separation technique to increase recycling of plastic.

This study considers direction types and formative characteristics by analyzing natural objets in contemporary fashion window display. The research methods are both literature review and content analysis based on images of contemporary fashion window display. The conclusions of this study are as follows. First, the direction types of natural objets in contemporary fashion window display expand objective outlines by maximizing the morphological form of objects. Second, a rhythmic sense expressed through a gradual repetition of patterns or a sequential arrangement of natural objects. Third, it represents a reversal of image accomplished through a modification of material on the natural objects. Fourth, a new space is created by transforming two dimensional forms of natural objects. The first formative characteristic of natural objects in contemporary fashion window display is exaggeration. This is expressed through either the expansion of the external volume, the collapsed form of natural objects, or the distortion of external colors. Second, it is a dynamics. This makes it possible to recall the dynamic image of the integration of the observer with a priori thinking by systematically sequencing objects or inducing a specific motion. Third, it is an abstraction. This provides an opportunity for the observer to find in a natural beauty by exchanging physical form or reinterpreting characteristic points. Fourth, it concerns eclecticism characteristic that objects created through the mutual fusion of heterogeneous elements indicates an aesthetic inspiration in a limited space by diverting conventional thinking toward natural objects with expansion of consciousness on formative arts.

Recent tendency in modern society for urban design and public space forming it recommended diversity of studies and design development, for the interest in urban design is increasing. In particular, street furniture being one of the important components to construct public space has been researched and developed in aspects of formative and emotional style, broken from the old way of the function-oriented purpose. It could be said that this results from the desire of human pursuing a well-off life, the new value standard regarding design and the life styles in mode. The new development of street furniture could be a creating the value-added source potentially being able to raise community, identity of nation and international competitiveness, beyond the primary purpose, namely the improvement of surrounding environment, and therefore the most of countries in the world are concentrating their life and death on development of design in reality. For this investigation the concept of city design, the basic content analysis of the street furniture and also the contents in the related sectors were reported. In order to develop the bench design, one of the representative items of the street furniture furthermore it was proceeded that basic process for the design like data searching for the object place and the existing case studies. On the basis of this the series of the design development processes such as idea sketch, computer rendering and drawing work were described step by step. The aim of this study is therefore to contribute in compiling the development processes of bench design as a new shape into a data and in utilizing it as a design case study and research material in the related sectors.
