In this paper, we propose a new cross bar embedded structure for improvement of attenuation characteristics along the different lossy media. A general characterization procedure based on the extraction of the characteristic impedance and propagation constant for analyzing a single MIS(Metal-Insulator-Semiconductor) transmission line used and an analysis for a new substrate shielding MIS structure consisting of grounded crossbars at the interface between Si and Sio2 layer using the Finite-Difference Time-Domain(FDTD) technique is used. In order to reduce the substrate effects on the transmission line characteristics, a shielding structure consisting of grounded cross bar lines over time-domain signal has been examined. The extracted, distributed frequency-dependent transmission line parameters as well as the line voltages and currents, and also corresponding equivalent circuit parameters have been examined as function of frequency. It is shown that the quality factor of the transmission line can be improved without significant changes in the characteristic impedance and effective dielectric constant.

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.

The significance of an integrated environmental management system implementation can be summarized into three sections. The first is that the paradigm of a permit system will be changed from the existing media-specific permits to cross-media permits. In the near future, the cross-media license will be granted based on the diagnostic results of the plant. The second is that it will be established through a social concensus, i.e., consultations with stakeholders and direct participation in the system design process of stakeholders. The third is that it will have flexibility in its operating system. In the near future, it will be possible to management an environment through its industrial workplace itself and determine if emission standards are being complied with or not through statistical methods. In addition there is also an urgent need for complementary parts in order to enhance the driving force of the integrated environmental management system which is based on transparency, reliability and flexibility. In other words, it is necessary to continuously promote in order to diffuse consensus and increase an understanding of implementation through an integrated environmental management system. It is also necessary to establish a new organization and educate authorized representatives so that they have the tools to smoothly perform the system.

Variety media based on the digital technology have emerged from the beginning of the 21th century and have competed with the traditional media in the advertisement market. With the high dependency upon the advertisement market, the Korean media industry has the urgent demand to increase it's pie. Korea regulator allowed PPL and private representatives, which resulted in low outcome. This study analysed the decision factors for the advertising market with the cross-sectional microeconomic data for 28 countries in OECD. The service industry, tax and GDP per capita affect negatively to the market growth rate, and unemployment positively. Therefore the market's growth speed would be slow down and the share of TV decreased. Therefore the two policies were suggested, increasing the direct payment by the audiences and retire of the inefficient broadcasters.

A diffusion process is often the main mechanism of soil gas/vapor movement in the vadose zone. The diffusion coefficients in the porous soil media are different from those in the free air phase by the reduction of available area for diffusion, tortuous diffusion path and variable cross section area along the diffusion path. To take account those effects of the diffusion process in the porous media, usually the terms of effective diffusion coefficient and tortuosity are have been used. However, as there are many differents definitions for the tortuosity, when the term of tortuosity is used, it is necessary to examine it throughly. Moreover, there are many different equations for the effective diffusion coefficient according to the investigators and the differences in the values of effective diffusion coefficients between the equations are not insignificant, the selection of the equation should be done with caution. In this paper, the different definitions of effective diffusion coefficient are examined and discussed. As well as definitions, the lots of availabe models for the diffusion coefficient in terms of porosities are compared. Also, the constrictiviy which explains the effect of cross sectional area change over the diffusion path was discussed.

A multi-media variable processing gain DS/CDMA system are considered. Two types of information sources with different rates and transmitting powers are assumed to be stransmitted simultaneously in the same channel. Average signal-to-noise ratios at the correlation receiver outputs for each type of information sources are analytically derived as funtions of partial cross-correlations between spreading code sequences. As the difference of information rates between information sources increase, the difference between signal-to-noise ratio regarding random spreading code and that regarding pseudo random spreading code increases (maximum 1.3dB). The result can provide a analytical tools for use in multi-media DS/CDMA system design.

Multicultural education is not about learning about a specific ethnic group, but rather developing the ability to cross the border of one's own culture and have conversations with people of other cultures. I think the purpose is to promote empathy and consideration. This study emphasizes the importance of developing multi-dimensional educational programs for all members of society for multicultural social integration, and it is necessary to lead personal, social and civic action movements to create a fair society through media-based multicultural literacy education. said that In order to achieve harmony and integration in a multicultural society, it is the most important to acknowledge cultural diversity and to discard cultural prejudices and inequalities for symbiosis between the mainstream culture and the minority culture. In particular, the United States and Germany, which have successfully led multicultural social integration, are comprehensive in all areas, including interculturalism based on peaceful coexistence and respect, labor market issues, vocational education issues, housing and health issues, and communication issues through media literacy. He led a multicultural national integration system with approaches and methods. Therefore, our multicultural education policy should also pursue a new paradigm that presupposes a change in the public's awareness of a multicultural society.

This study determines how social media users (SMUs) verify the information they come across on the Internet. It determines SMUs' perception of online fact-checking services in terms of their ease of use, usefulness, and trust. By conducting a focus group discussion and key informant interviews, themes were derived in determining fact-checking practices while a survey was further conducted to determine such perceived ease of use, usefulness, and trust in fact-checking services. The thematic analysis revealed major information verification practices, such as cross-checking and verifying with other sources, inspecting comments and reactions, and confirming from personal and social networks. The results showed that SMUs considered fact-checking services easy to use. However, a concern was raised about their usefulness stemming from the delayed action in addressing the information issues that need to be verified. As to perceived trust, it was found that SMUs have reservations about fact-checking services. Finally, it is believed that fact-checking services are expected to be credible and need to be promoted to mitigate any form of fake news, particularly on social media platforms.

Interactive media is a buzz word in current creative industry, but many of related fields have different understanding of the meaning of "interaction" in interactive media. This aspect is often the cause of difficulties communication and becomes an obstacle to joint researches. Thus this study attempts to develop a theoretical categorization of the meanings of interaction in interactive media. For this, this study first gathered various interpretations about what is interaction and build a rough classification. Then the classification is supplemented and amended over three times through FGIs of the interactive media related experts. This theoretical categorization is expected to help smooth cross-disciplinary studies and integrated technology development in interactive media.

Purpose The purpose of this study is to explore the pattern of user response and it's duration time through social media content response analysis. We also analyze the characteristics of content quality factors which are associate with the user response pattern. The analysis results will provide some implications to develop strategies and schematic plans for the operator of regional marketing on the SNS. Design/methodology/approach This study used mixed methods to verify the effects and responses of social media contents on the users who have concerns about regional events such as local festival, cultural events, and city tours etc. Big data analysis was conducted with the quantitative data from regional government SNSs. The data was collected through web crawling in order to analyze the social media contents. We especially analyzed the contents duration time and peak level time. This study also analyzed the characteristics of contents quality factors using expert evaluation data on the social media contents. Finally, we verify the relationship between the contents quality factors and user response types by cross correlation analysis. Findings According to the big data analysis, we could find some content life cycle which can be explained through empirical distribution with peak time pattern and left skewed long tail. The user response patterns are dependent on time and contents quality. In addition, this study confirms that the level of quality of social media content is closely relate to user interaction and response pattern. As a result of the contents response pattern analysis, it is necessary to develop high quality contents design strategy and content posting and propagation tactics. The SNS operators need to develop high quality contents using rich-media technology and active response contents that induce opinion leader on the SNS.
