Depaysement, suggested by the well-known surrealist Rene Magritte, has been used for and applied to many media. Application of depaysement through various media such as TV, commercial, and advertisement, attempted to provide interest by deviation from fixed ideas and visual shock, placing common objects in new and strange environment. The study applied screen projection mapping using a transparent screen and objet for different purposes to projection mapping media, applying depaysement to the artwork 'Illusion' in order to suggest visual pleasure, possibility as a new media, and projection mapping using transparent screen and objet. The work cases were suggested by applying expressive methods and effects according to three classifications - modulation of space, combination of conflicting images, and transformation and change of objects - in depaysement, and analyzed by types based on classification of the layout, typography, image, color, and time. Through 'Illusion,' new objet and characteristics of the media are applied and expanded by using projection mapping and depaysement.

The case of Dance Chang-jak-san-shil, a dance performance support project linked to digital media, was analyzed from the perspective of liveness. The purpose was to examine the limitations of the liveness and to suggest ways to overcome them. The research case was focused on the factors of the time and space and audience (the sharing of field and acceptance experience) of the creative production room that supports works based on the creativity of dance performances. As a result, active SNS for accessibility of performing arts, expansion of access to art through the use of teaching media of art education through archiving, multi-dimensional access and provision for inducing audience participation and creative appreciation in one-way digital media transmission, provision of copyright protection devices, and audience to enter offline. As a long-term strategy for the future of the performing arts field, I would like to present the need for a change in the communication with the audience and experimental works that combine art and technology.

We implement an interactive 3D audio broadcasting terminal which synthesizes an audio scene according to the request of a user. Audio scene structure is described by the MPEG-4 AudioBIFS specifications. The user updates scene attributes and the terminal synthesizes the corresponding sound images in the 3D space. The terminal supports the MPEG-4 Audio top nodes and some visual nodes. Instead of using sensor nodes and route elements, we predefine node type-specific user interfaces to support BIFS commands for field replacement. We employ sound spatialization, directivity/shape modeling, and reverberation effects for 3D audio rendering and realistic feedback to user inputs. We also introduce a virtual concert program as an application scenario of the interactive broadcasting terminal.

An understanding of particle-particle interactions in filtration requires studying the detachment as well as the attachment of nanoparticles. Nanoparticles captured in a granular media filter can be released by changing the physicochemical factors. In this study, the detachment of captured silver nanoparticles (AgNPs) in granular media filtration was examined under different ionic strengths, ion type, and the presence or absence of natural organic matter (NOM). Filtration velocity and ionic strength were chosen as the physical and chemical factors to cause the detachment. Increasing filtration velocity caused a negligible amount of AgNP detachment. On the other hand, lowering ionic strength showed different release amounts depending on the background ions, implying a population of loosely captured particles inside the filter bed. Overall detachment was affected by ionic strength and ion type, and to a lesser degree by NOM coating which resulted in slightly more detachment (in otherwise identical conditions) than in the absence of that coating, possibly by steric effects. The secondary energy minimum with Na ions was deeper and wider than with Ca ions, probably due to the lack of complexation with citrate and charge neutralization that would be caused by Ca ions. This result implies that the change in chemical force by reducing ionic strength of Na ions could significantly enhance the detachment compared to that caused by a change in physical force, due to a weak electrostatic deposition between nanoparticles and filter media. A modification of the 1-D filtration model to incorporate a detachment term showed good agreement with experimental data; estimating the detachment coefficients for that model suggested that the detachment rate could be similar regardless of the amount of previously captured AgNPs.

This study suggests the popular culture theory as a basic framework to find out the characteristics of contemporary fashion show meeting the popular culture, and describes that the show is the popular culture of this generation. The culture is the way of our life unifying the world at common area of human being. The popular culture is to subdivide it into the public culture that shares aesthetic taste, and to borrow each other and develop it mutually because of the collapse of dichotomous boundary with high quality culture, and to represent the people’s thought and behaviour expanding their areas. The author has examined the characteristics of popular culture of modern fashion show by four collections, that is, commercialism, mass media, political relationship and interaction, etc： Firstly, at the commercialism, the fashion show combines it with other genre organically to do mass production and sales and produces cultural consumption goods supplying a lot of sight-seeing. Secondly, at the mass media, the image of contemporary fashion show has been spread out with mass media such as fashion magazines, cable TV and Internet beyond time and space to produce advertisement effects and makes new fashion and bring democratic culture. Thirdly, at political relationship, the fashion in its peak can make a big stream of wealth, so that it plays important roles under governmental regulations in this era and governments make efforts to support and develop it. Lastly, at interaction, the fashion show shares media functions to let users participate in the program and to exchange information as a feedback to influence each other.

This thesis suggested that the 'customized' marketing would be a new strategy in terms of a marketing in the digital media age under the circumstances where a form of marketing was evolving in accordance with the convergence of digital media. Because of the media environment due to an 'individualization', the strategy would meet an individual demand of a consumer in a rapidly changing environment. The best marketing to capture a 'customer's heart' is not a brand that first entered the market, but the one that is first settled in a customer's heart. If a differentiated interactive marketing strategy is equipped, it is possible to capture a completely new market space ad create a profit over several years. In the aspect of an effect of a digital marketing, first, a concept relating to an interaction between a consumer and a producer is important. Secondly, the important one is an empathy marketing which is an emotional marketing through a brand image beyond a product. Thirdly, the author studied an orally transmitted marketing effect through digital media.

Today, the structure of terrorist organizations in the form of a variety of network complexity are evolving. However, terrorist organization not combining randomly generated network but preferential attachment a network. So, it's research should be preceded a better understanding about the characteristics and type of terror network for a effective counter-terrorism policy of law enforcement. In addition, the appropriate response strategy have to technique establish in an era of smart media. In particular, homegrown terrorist attacks on unspecified people without boundaries of countries and regions unlike the traditional terrorism. Also, homegrown terrorism are violence and criminal activity by new various of religion, politics, philosophy. Besides the extreme members of homegrown terror networks went grow up through the evolutionary process in the age of smart media. Law enforcement agencies must identify the terrorist network at the national level. Therefore, terror networks evolving in the online space, forming a radical homegrown terror organizations have access to the network. Intelligence community track terrorist networks and to block the negative aspects of the smart media outlets should be considered.

The purpose of this study is to examine the works of choreographer Philippe $Decoufl{\acute{e}}$ and the performance costumes designer Philippe Guillotel, and identify the intrinsic values shown in the formative characteristics in their works. And it proposes a vision and a direction for the development and performance of modern fashion phenomenon of media convergence performing arts complex. The results were as follows. First, the performance characteristics shown in Philippe $Decoufl{\acute{e}}$'s art pattern applies dynamic improvisation, decategorization reflected in the media interactivity, time and space of a variable scalability, complex artistic genres and transcends cultural boundaries. Second, the characteristics of the performance costume can be described as a co-existence between dynamics of aesthetic layers, 'Media body' represented by the interaction of the compounds with the technology, and integrated variable expandability. And aesthetic values inherent in the performance costumes are summarized as abstraction, playfulness, reproducibility, and theatricality. Modern fashion performance and limited production of the center 'costumes' in the fashion images can be used in diverse ways, and innovative marketing has gone through a change in image production. Metaphysical text of the advanced performance genre can be presented in a new perspective to fashion derivatives 'Media body'. And the aesthetics of popular culture kitsch, the grotesque, and surrealism in theater will produce creative stage direction.

In this paper, optimized media data retrieval and transmission based on the Hybrid CDN/P2P architecture and selective storage through user's prediction of requestability enable seamless data transfer to users and reduction of unnecessary traffic. We also propose a new media management method to minimize the possibility of transmission delay and packet loss so that media can be utilized in real time. To this end, we construct each media into logical segments, continuously compute weights for each segment, and determine whether to store segment data based on the calculated weights. We also designate scattered computing nodes on the network as local groups by distance and ensure that storage space is efficiently shared and utilized within those groups. Experiments conducted to verify the efficiency of the proposed technique have shown that the proposed method yields a relatively good performance evaluation compared to the existing methods, which can enable both initial latency reduction and seamless transmission.
