MPEG-I Visual group is actively working on enhancing immersive experiences with up to six degree of freedom (6DoF). In virtual space of omnidirectional 6DoF, which is defined as a case of degree of freedom providing 6DoF in a restricted area, looking at the scene from another viewpoint (another position in space) requires rendering additional viewpoints called virtual omnidirectional viewpoints. This paper presents the performance analysis on view synthesis, which is done as the exploration experiment (EE) in MPEG-I, from a set of 360 videos providing omnidirectional 6DoF in various ways with different distances, directions, and number of input views. In addition, we compared the subjective quality between synthesized images with one input view and two input views.

This case study research analyzes the cross-artistic project Connect, BTS and its relationship to transmedia branding, meaning-making and spatiality. After an overview of the argument and a section on methodology, the reader will find the analysis of the case study. Thanks to the use of a qualitative approach, this examination of Connect, BTS unveils the ways in which this initiative becomes a location that allows a reconceptualization of space that fosters plurality, exchange, and subjectivity. Connect, BTS unites seemingly incompatible fields under one project, favoring the co-creation of meanings among different artists, BTS, ARMY (the group's fans), business partners and viewers. This process has been investigated through content analysis, exploring Connect, BTS's transmedia strategies from branding to storytelling, to evaluate their efficacy in regard to brand identity, brand experience, and brand trust. The paper will also explore the variety of layers and spatial dimensions contained in Connect, BTS, which flow from art to the music industry, material and digital space, various market sectors and media. In light of this, Connect, BTS embraces a galaxy of separate semantic units into an extended liminal continuum that does not discount difference.

Eringen's nonlocal thermoelasticity theory is used to study wave propagations in a rotating two-temperature thermoelastic half-space with temperature-dependent properties. Using suitable non-dimensional variables, the harmonic wave analysis is used to convert the partial differential equations to ordinary differential equations solving the problem. The modulus of elasticity is given as a linear function of the reference temperature. MATLAB software is used for numerical calculations. Comparisons are carried out with the results in the context of the dual-phase lag model for different values of rotation, a nonlocal parameter, an inclined load, and an empirical material constant. The distributions of physical fields showed that the nonlocal parameter, rotation, and inclined load have great effects. When a nonlocal thermoelastic media is swapped out for a thermoelastic one, this approach still holds true.

This study was conducted in a glasshouse to examine the possibility of producing tomato plug seedlings in a newly-developed inert phenolic foam medium. Plug seedlings of 'Madison' tomato were grown in four pellet type media, Grodan rockwool, UR rockwool, phenolic foam LC, and phenolic foam LC-lite. Seed germination was checked for 7 days. Seedling growth was measured at 19 days after sowing. The greatest germination was obtained in the phenolic foam LC and phenolic foam LC-lite. Plant height, hypocotyl length, leaf area, dry weight, and fresh weight were significantly greater in the rockwool medium than those in the other media. However, the T/R ratio and stem diameter were the greatest in the phenolic foam LC than those in the other media. The total porosity and container capacity of the phenolic foam LC was higher than in the other media. The air space (%) was lowest in the phenolic foam LC. Overall, the phenolic foam LC and phenolic foam LC-lite produced seedlings with similar growth as the rockwool. These results suggested that both phenolic foam LC and phenolic foam LC-lite have potential to be used in production of plug seedlings of 'Madison' tomato.

In recent years, new media art is developing to play its roles as a means of remediation to overturn, reuse, and alter the old technologies rather than technology-dependent art to accept new technologies and use them as artistic tools. Here, the concept of new should mean looking at the old technologies in an indirect way and finding new meanings in them rather than presenting new technologies. The starting point of this study was the concept of spatialization in which the concept of new media art would externalize games from inside to outside the screen in gamification-applied spaces. Participatory new media art adds a platform for viewer's participation and utilizes the entire space of the exhibition hall instead of allowing for simple viewing at the exhibition hall. The study focused on the changes and phenomena in the process of games belonging to the artistic space through the interactivity of gamification. Here, the premise was that gamification meant the "spatialization of games." The study examined several cases of games being altered in the spatialization process to figure out interactivity for viewers and developmental directions for interface design at a gallery.

This paper has attempted to propose a more progressive direction for U-environmental sculptures in a ubiquitous urban space in terms of usability, service, function and formative characteristics that enhance user satisfaction with these sculptures. For this, Media Pole, a U-environmental sculpture on Gangnam U-Street, has been examined. The results of this study are as follows: First, a study of user satisfaction was planned after establishing levels of satisfaction in terms of service, function and formative characteristics. In terms of satisfaction by the section of Media Pole, the public transportation map was the most influential in service while street culture and beauty of shape were critical in function and formative characteristics, respectively. In the relationship between satisfaction by section and overall satisfaction, furthermore, functional satisfaction had the biggest influence. Therefore, the development of human-centered functional factors which have pleasant and touching stories to facilitate communication with citizens are important in order to develop various Media Pole contents to enhance user satisfaction with the U-environmental sculpture and allow it evolve into a Gangnam landmark Since we are in the initial stage of a U-city, there are many problems that need to be addressed such as a lack of natural beauty, poor material quality of environmental sculptures, absence of storytelling, poor technology, lack of content, poor profitability and lack of means of social communication. In the end, the development of a comfortable, people-friendly space and U-environmental sculptures are needed in consideration of economic, social and cultural aspects instead of focusing on advanced technology only.

GPS location information storage included in the HD black box is using a unique manner for each manufacturer does not have a specific standard. In this paper, in order to overcome the limitations of the storage space and thereby the image quality according to store GPS position information deteriorate to solve the problems that cause, we propose the location information concealment method included in the HDTV video content using a essential hidden region. HDTV video content is a Border Extender of 8 lines in the frame to the bottom of the compression will be required. This was inserted into the image of a gray scale used in block form in order to space the current position information is concealed to prevent image degradation. The proposed method was confirmed using real HD black box, there are more difficult to interpret the format of the ASCII code re-edit the location information when the compression effect disappears with the existing security zones added. Therefore, the proposed method is suitable for location-based services, such as Facebook or Youtube videos.

This paper presents a study of soil-structure interaction problems using infinite elements. The infinite elements are formulated for homogeneous and layered soil media, based on approximate expressions for three components of propagating waves, namely Rayleigh, compressive and shear waves. The integration scheme which was proposed for problems with single wave component by Zienkiewicz is expanded to the multi-wave problem. Verifications are carried out on rigid circular footings which are placed on and embedded in elastic half space. Numerical analysis is performed for a containment structure of a nuclear power plant subjected seismic excitation.

The wave-kinetic numerical method is used in simulating the irradiance scintillations of optical wave through a two-dimensional random medium containing weak Gaussian fluctuations of the refractive index. The results are compared to existing analytical or numerical results. The wave-kinetic method is a phase-space ray-tracing method for certain key ray trajectories, and the irradiance is calculated by reconstructing the entire beam from these trajectories. The strength of the wave-kinetic method lies in the fact that it can be applied to any type of random media.

MIMO(multi-input multi-output) 시스템은 여러 개의 송 수신기를 이용하여 정보를 전송하여 주파수 대역폭의 확장 없이 채널 용량을 증가시킨다. 그러나 공간 다이버시티를 증가시키는 STBC(space time block code)를 제외한 공간 다중화 방식을 사용하는 LDC(linear dispersion code) 시스템은 변조 레벨이 증가할수록 수신기의 복잡도가 기하급수적으로 높아진다. 본 논문에서는 하이브리드 LDC-MIMO 시스템을 적용하여 낮은 변조 레벨에서도 전송량을 증가시키면서 수신기의 복잡도를 감소시킬 수 있는 시스템을 제안한다. 제안된 알고리듬은 컴퓨터 시뮬레이션을 통하여 검증하였다.
