Diversity of available communication media has increased as the use of Internet and mobile technology increased rapidly. The traditional media tend to transform their roles and functionality. This change brings about the expansion of the span of media to be selected by users. In this study, we examined the characteristics of emerging communication media use based on Niche Theory. Online communication media in this study include Internet messenger, mobile phone, and e-mail. We also analyzed the relationship between the nature of task and the selection of communication media, that is, the effects of communication contexts(formal vs. informal, notification vs. request, superior vs. inferior) where by the communication partners are involved. The result of this study, mobile phone had the highest niche competitive superiority in all communication contexts, and internet messenger and e-mail made difference according to communication contexts. Also, we can notify internet messenger and e-mail have a mutual substitutive relationship by analysis of niche overlap.

With the rapid development of digital media, there has been a huge change in a way of communication, a process of information diffusion and a role of traditional media. Not like mass media, social media enables users to generate and tap into the opinions of a larger world. From that reason, social media is impacting marketing strategies. However, still social media marketing researches just focus on case study, analysis of users motivation or analysis of power user's usage pattern. Word-of-mouth has always been important especially in marketing area. In social media, word-of-mouth depends on each user that's why this research focuses on individual user's activity in SNS. I defined 4 factors (produce, diffusion, network size, activity of network size enlarge) that are effect on activity and verified hypothesis by multiple regression analysis, hierarchical regression analysis and moderated multiple regression.

User and media are in close coalition with each other in the 21st century's era of New-Media. The new users exposed to the New-Media environment have a complete understanding of the digital media environment, and are also taking on the role of an active identity in the formation of culture in new media. In the field of spatial design, creative spatial interfaces designed through various methods derived from the New-Media environment and technology that weren't even imaginable in the past ultimately came to exist in a mutual relationship with the user, the people. This study is in the same context as studies looking into the establishment of design in media art and digital media space in the New-Media environment. Media art is an outcome arising from the demand towards new art combined with the attempts towards accepting various media as a means for artistic expression. Media art seizes to being a mere part of art, but more. This study aims to look into the theoretical basis of New-Media and define the design process through the expressional characteristics and triggered thoughts thereof. Lastly, the results of the research will be put together to produce the final results. Such analysis process will be the basis of the creation of a new paradigm and spatial thought, and allow people to be concerned about the various changes in spatial formation.

China media environment has drastically changed leading to the an inevitable change of public opinion ecology. Empirical studies have focused less on public opinion guidance, which forms an important component of the government officials' media literacy. This study applied quantitative method in the investigation of media literacy in China. Ideally, media literacy is measured from media cognition, media contact, media usage under the view of public opinion guidance. The findings reveal that the existing problem on 1) incorrect media cognition and public opinion guidance; 2) insufficient contact of personal social media 3) improper tendencies in the use of media to guide the public opinion, especially, on confidential information. Consequently, in order to improve media literacy in China government officials, enhancement of their basic knowledge on news diffusion and public opinion is necessary. Secondly, to effectively deal with "agenda settings", it is important for the government to consider the provision of valuable information and platforms to effectively spread information. So they need to learn how to personally and officially use social media platforms such as Weiboa and Wechat. This ensures they have maximized their potential to acquire valuable information and spread them on valuable platforms. Thirdly, government officials should be able to analyze and understand public opinion trends for official and personal use. Finally, they should understand the development of public opinion and the how online public opinion laws are formed and the target group.

우리나라 온라인 저널리즘 지형의 과거, 현재, 미래는 무엇보다 포털 뉴스서비스와 밀접한 연관이 있다. 전통 저널리즘에서 한정된 뉴스미디어는 뉴스 생산과 유통을 동시에 수행하기 때문에 소비를 완전히 장악할 수 있었다. 이후 다매체다채널 시대에는 뉴스미디어가 큰 폭으로 증가하고 이에 따라 뉴스 생산이 폭발적으로 늘어나면서 수용자의 선택이 중요하게 됐다. 온라인 저널리즘 환경에서는 각종 뉴스 이용을 간편하게 만든 포털 뉴스서비스에 대한 이용의 집중, 뉴스미디어 브랜드보다는 뉴스 콘텐츠에 집중하는 뉴스 소비의 특성 등으로 인해 뉴스 유통이 가장 중요한 영역으로 부각됐다. 포털 뉴스서비스가 온라인 저널리즘의 상징적 존재가 되면서 뉴스 유통 중심의 우리나라 저널리즘 지형이 완성된 것이다. 뉴스 유통만을 담당하는 포털 뉴스서비스가 뉴스를 생산하는 언론사닷컴이나 인터넷신문보다 더 큰 영향력을 가진다는 것은 언론 권력의 변화를 의미한다. 이로 인해 기존 뉴스미디어와 포털 뉴스서비스의 갈등이 곳곳에서 목격된다.

The change of digital technology caused not only the whole human life but also the change of a thinking form and an expression method of human beings. Also, the interactive communication structure became to form in space structure, and space users also get changed to an active system. The interaction between a human being and space, which uses digital media as a medium, makes a human being experience sensitivity through a cognitive process of a human being. The present research aimed to find out characteristics and expression of emotional space applied with digital technology based on the relationship between media space and cognitive functioning and to realize new emotional space. The research method was to define on digital media and experience by cognition of a human being through a literature research and a precedent research and to consider on approach to emotional space through experience of a cognition process like this. Based on the theory like this, the present research progressed by focusing on dramatized characteristics of experience in the digital media space and emotional space expression by induced characteristics. Through the analysis like this, the space applied with digital media could appear as a field of communication that can experience by forming mutual relation through perception of a human being. Additionally, the space induces active participation of a human being through various productions of media and responds to movement, and thus, this suggested infinite possibility as emotional space that can try new experience by stimulating a sense as effect of a cognitive process of a human being.

The solids and the fluids in porous media have a relative velocity to each other. Due to physically and chemically different material properties and their relative velocity, the behavior of saturated porous media is extremely complicated. Thus, in order to describe and clarify the deformation behavior of saturated porous media, constitutive models for deformation of porous media coupling several effects such as flow of the fluids or thermodynanical change need to be developed in frame of Arbitrary Lagrangian Eulerian (ALE) description. The aim of ALE formulations is to maximize the advantages of Lagrangian and Eulerian elements, and to minimize the disadvantages. Therefore, this method is appropriate for the analysis of porous media that are considered for the behavior of the solids and the fluids. In this work, governing equations of porous media based on ALE description are obtained from governing equations in frame of updated Lagrangian description. Then, weak forms of these equations are derived using arbitrary weighting functions.

Porous media consist of physically and chemically different materials and have an extremely complicated behavior due to the different material properties of each of its constituents. In addition, the internal structure of porous media has generally a complex geometry that makes the description of its mechanical behavior quite complex. Thus, in order to describe and clarify the deformation behavior of porous media, constitutive models for deformation of porous media coupling several effects such as flow of fluids of thermodynamical change need to be developed in frame of Arbitrary Lagrangian Eulerian (ALE) description. The aim of ALE formulations is to maximize the advantages of Lagrangian and Eulerian methods, and to minimize the disadvantages. Therefore, this method is appropriate for the analysis of porous media that are considered for the behavior of solids and fluids. First of all, governing equations for saturated porous media based on ALE description are derived. Then, weak forms of these equations are obtained in order to implement numerical method using finite element method. Finally, Petrov-Galerkin method Is applied to develop finite element formulation.
