In this study, we experimented with experience of digital signage using Virtual Reality technology, and the difference between presence and interactivity in brand experience and digital signage attitude. We conducted a two-way MANOVA analysis with cognitive presence, emotional presence, and media presence as the independent variable and interactivity level(high vs low) as dependent variables and the brand experience and attitude as dependent variables. First, cognitive presence was found to be most effective through behavioral experience when low interactivity. Second, emotional presence also has a positive effect on emotional experience when the level of interactivity is low. Third, media presence has a positive effect on emotional experience if the level of interactivity is low. This study suggests a communication strategy to communicate presence according to the characteristics of media strategy and technology through appropriate level of interactivity when using digital technology. Future research requires a qualitative approach rather than a quantitative one in terms of interactivity.

The digital environment, which has been rapidly developing since the beginning of the 21^st century, has become more specific due to COVID-19, and marketing strategies are rapidly changing to suit purchasing activities of Generation MZ, whose online purchases are becoming the center of their lives. A public relations agency is generally responsible for all aspects of making a client's product or service visible to the public through various forms of media. Among them, a company that performs only fashion-related tasks is called a "fashion PR agency". Now, the fashion industry is also centered on the e-commerce environment, and various digital marketing strategies have been developed and directly related to sales. This study examined the current status of online media and digital marketing, analyzes the aspects of fashion brand promotion strategies and methods in the e-commerce era, focusing on the work of fashion PR agencies, and suggests the direction of new online and offline promotion methods based on marketing and technological aspects. As a result of the study, first, theories on strategies for online media and digital marketing were examined, and found that the amount of online promotion has recently increased and become more specialized. Second, this study examines the concept of fashion PR agencies and analyzed their main tasks through interviews with fashion PR professionals. Third, based on successful online fashion promotion cases, the study analyzed fashion promotion strategies and methods that are being integrated online and offline in the e-commerce era. The main methods included SNS strategy, content strategy, performance strategy, influencer strategy, and event strategy, and it is suggested that integrated management is necessary for consistent brand image management, and an IMC (Integrated Marketing Communication) strategy, which intensively manages all strategies, should be employed.

The cinema of Peter Greenaway has consistently engaged questions of the relationship between the arts and particularly the relations of image and writing to cinema. When different types of images are correlated and merged with each other on the borders of painting, photography, film, video and computer animation, the interrelationships of the distinct elements cause a shift in the notion of the whole image. This analysis proposes to articulate the complex relationship between the 'interartial' dimension and the 'intermedial' dimension in Peter Greenaway's film, (1991). If the interartiality is interested in the interaction between various arts, including the transition from one to another, the intermediality articulates the same type of relationship between two or more media. The interactional relationship is the same on both sides; on the contrary, the relationship between art and media does not show the same symmetry. All art is based on one or more media - the media is a condition existence of art - but no art can't be reduced to the status of media. This suggests that if the interartiality always involves the intermediality, this proposal may not be reversed. First, we analyse a self-conscious investigation into digital art and technology. Prosospero's Books can be read as a daring visual essay that self-consciously investigates the technical and philosophical functions of letters, books, images, animated paintings, digital arts, and the other magical illusions, which have been modern or will be post-modern media to represent the world. Greenaway uses both conventional film techniques and the resources of high-definition television to layer image upon image, superimposing a second or third frame within his frame. Greenaway uses the frame-within-frame as the cinematic equivalent of Shakespeare's paly-within-play : it offer him the possibility to analyse the work of art/artist/spectator relationship. Secondly, we analyse the relationship between the written word, oral word and the books. Like the written word, the oral word changes into a visual image: The linguistic richness and nuances of Shakeaspeare's characters turn into the powerful and authoritative, but monotone, voices of Gielgud-Prospero, who speaks the Shakespearean lines aloud, shaping the characters so powerfully through his worlds that they are conjured before us. Specially each book is placed over the frame of the play's action, only partially covering the image, so that it gives virtually every frame at least two space-time orientations. Thirdly, we try to show how Peter Greenaway uses pictorial references in order to illustrate the context of the Renaissance as well as pictorial techniques and language in order to question the nature of artistic representation. For exemple, The storm is visualised through reference to Botticelli's : the storm of papers swirling around the library is constructed to look like a facsimili copy of Michelangelo's Laurentiana Library in Florence. Greenaway's modern mannerism consists in imposing his own aesthetic vision and his questioning of art beyond the play's meta-theatricality: in other words, Shakespeare''s text has been adapted without being betrayed.

In this paper, we study the response of several anisotropic systems to buried transient line loads. The problem is mathematically formulated based on the equations of motion in the constitutive relations. The load is in form of a normal stress acting with arbitrary axis on the plane of monoclinic symmetry. Plane wave equation is coupled with vertical shear wave, longitudinal wave and horizontal shear wave. We first considered the equation of motion in reference coordinate system, where the line load is coincident with symmetry axis of the orthotrioic material. Then the equation of motion is transformed with respect to general coordiante system with azimuthal angle by using transformation tensor. The load is first described as a body force in the equations of the motion for the infinite media and then it is mathematically characterized. Subsequently the results for semi-infinite spaces is also obtained by using superposition of the infinite medium solution together with a scattered solution from the free surface. Consequently explicit solutions for the displacements are obtained by using Cargniard-DeHoop contour. Numerical results which are drawn from concrete examples of orthotropic material belonging to monoclinic symmetry are demonstrated.

In this paper we propose a method of detecting moving object in H.264/AVC bitstream by representing the $4{\times}4$ block partition units as nodes of graph. By constructing hierarchical graph by taking into account the relation between nodes and the spatial-temporal relations between graphs in frames, we are able to track small objects, distinguish two occluded objects, and identify objects that move and stop alternatively.

본 논문은 문장 분석에 의하여 의미 관계를 생성하고 의미 네트워크에 의하여 유사한 의미 관계를 고려하는 의미 중심의 웹 텍스트 검색 기법에 대하여 논의한다. 기존의 웹 텍스트 검색은 단어만을 혹은 의미 관계만을 고려한 검색이었다고 할 수 있다. 그러나 문장 분석에 의한 의미 관계의 생성과 의미 네트워크에 의한 유사한 의미 관계의 고려는 기존의 단어 중심 혹은 의미 관계 중심의 검색 한계를 넘어서 유사한 의미 관계를 고려한 좀 더 포괄적이고 계층적인 검색을 가능하게 할 것으로 생각된다.

The design of space, which focuses on human senses and perception, has become more prominent. It can be understood as the space needed for a field of experience. Phenomenological attitude focuses on the relations between human in the context of their environment. The experiences generated were used as a method of design. The method guides a formation of active space through phenomenological experience in interior space as well as architecture. To stimulate a phenomenological sensitive experience, the parameters for certain experiences were connected to the five senses, finally creating a concrete space. Water, light, air, vapor, and earth as architectural media are connected to the five senses and lead to intermediation from abstract to actual. In particular, water is deeply rooted in peoples subconsciousness and stimulates our instincts. Using water by effectively combining its symbols and physical characteristics will be a method to reinforce the experience with a given space. This study will examine the need for space experience and characteristics of water as an essential elements for perception experience and present possible experimental design.

Video games are an alternative channel for public health authorities constantly striving to reach target audiences and make positive changes. The objective of this research is to address effectiveness of health games as a health promotion technology for anti-smoking communication. This study tested the impact of advertising message types and voice-over relative to anti-smoking persuasion. By using commercial-level custom-made first person shooter (FPS) games, two experimental studies demonstrated usefulness of applying health games to change a player's attitude towards smoking. In particular, an interactive in-game message with a persuasive voice over was the most effective method to change targets' attitude towards smoking. Findings of our research offer meaningful insight on health promotion research and provide possible directions for future anti-smoking communication using health games.

Transformation optics methodology provides a new pathway for designing novel devices. It is based on changing a material’s permittivity and permeability. A design for changing the appearance of an object by transformation optics methodology is proposed here. Through a certain transformation, the relations of the metric spaces and the calculation of the material parameters are derived, and the aim of changing the apparent size of an object can be realized. Full wave simulations are performed to validate the proposed device’s performance. It is possible to think that the methodology will improve the flexibility of designing interesting applications in microwave and optical regimes.

The purpose of this study is to illustrate the propagation of the shear waves (SH-waves) in a prestressed hetrogeneous orthotropic media overlying a pre-stressed anisotropic porous half-space with self weight. It is considered that the compressive initial stress, mass density and moduli of rigidity of the upper layer are space dependent. The proposed model is solved to obtain the different dispersion relations for the SH-wave in the elastic-porous medium of different properties. The effects of compressive and tensile stresses along with the heterogeneity, porosity, Biot's gravity parameter on the dispersion of SH-wave are shown numerically. The wave analysis further indicates that the technical parameters of upper and lower half-space affect the wave velocity significantly. The results may be useful to understand the nature of seismic wave propagation in geophysical applications and in the field of earthquake and material science engineering.
