The Finite Element Solutions Is reported on solid-liquid phase change in porous media with natural convection including freezing. The model is based on volume averaged transport equations, while phase change is assumed to occur over a small temperature range. The FEM (Finite Element Method) algorithm used in this study is 3-step time-splitting method which requires much less execution time and computer storage the velocity-pressure integrated method and the penalty method. And the explicit Lax-Wendroff scheme is applied to nonlinear convective term in the energy equation. For natural convection including melting and solidification the numerical results show reasonable agreement with FDM (Finite Difference Method) results.

In the current analysis, we examine news coverage data widely used in media studies. News coverage data is usually time series data to capture the volume or the tone of the news media's coverage of a topic. We first describe the distributional properties of autoregressive conditionally heteroscadestic(ARCH) effects and compare two major American newspaper's coverage of U.S.-North Korea relations. Subsequently, we propose a change point detection model and apply it to the detection of major change points in the tone of American newspaper coverage of U.S.-North Korea relations.

중국의 미디어 영역에서는 정치적 경제적 제도적 변화에 따라 생성적 변화의 흐름이 존재해왔다. 드라마 생산 영역에서 시장체제가 도입된 이후에는 정부 대리인이자 시장 관리의 역할을 하는 '제편인(制片人)'이라는 사람들이 자생적으로 출현하게 되었으며 국가는 곧 이 '제편인'에게 합법적 자격과 권한을 부여함으로써 제도화하여 제도권 내로 흡수시켰다. 이 과정에서 '드라마 제편인 제도'는 사회주의 시장경제라는 특수한 환경 하에서 정부의 직접관리에서 간접관리, 그리고 자아검열로의 변화 과정을 잘 드러내는 중국식 관리 모델을 보여준다고 할 수 있다. 또한, 인터넷이 보급되면서 풀뿌리 미디어를 비롯한 다양한 미디어가 출현하였고, 네티즌들의 참여와 생산 활동으로 문학 영역에 인터넷 문학이라는 새로운 장르가 출현하기도 했다. 그리고 동영상과 풀뿌리 미디어의 플랫폼으로 역할했던 일부 사이트가 자체적으로 콘텐츠 생산을 하게 되면서 미디어로서 기능하게 되었다. 본래 인터넷을 IT 산업의 일부로 양성하였지만 인터넷이 미디어로서 기능하며 새로운 미디어 지형을 형성하게 되자 점차적으로 이에 대한 규제와 제도를 갖추어나가기 시작했으며, 이후 전면적인 인터넷 미디어 콘텐츠 관리 및 규제의 방향으로 나아가기 시작했다. 미디어 영역에서 생성적 변화의 흐름이 출현하고 이것이 관방의 미디어 정책에 수렴되는 생성-수렴의 양상이 반복되어 나타나고 있다.

The purpose of this study is to pronounce design trends in contemporary architecture collaborated with new media art concept. Currently, the prevalence of media presence has evolved perspectives on contemporary aesthetics today. To make clear demonstration on the issue, this study categorized new media art's expressional characteristics applied in the contemporary architectural design in conjunction with analytical researches on typologies and expressional characteristics appear in new media art. More specifically, the study selected architects who adopted new media art's expressional characteristics into their works from the year 2000 and performed analytical case studies with regard to the effect of the new media art into their architectural practices. By following methodologies mentioned above, conclusively the study categorized distinct expressional characteristics appears in contemporary architecture as a result of merging with new media art. The characteristics of the new media art appeared in contemporary architecture are categorized into three groups such as the design controlling external environment, the design utilizing web environment and the design participated by users. These observation could be translated that architects could present interactive design between users and building as a result from architect's capability of designing protocols which generate variable forms, colors and patterns in architecture. In particular, architecture utilizing web environment has characteristic capability of configurating user's program in virtual space. Also it is anticipated to suggest new patterns in generating architectural programs and forms. These patterns would not recognize the city merely as an incident or fragmented image but would configurate forms and images constructed by individual notional character. In conclusion, the architecture itself is expected to perform as media to open up opportunities that enables to contribute in expediting interactions among environment, users, and buildings by deviating from perspectives of representation as an object expressed in modernism architecture or as a classical decoration in post-modernism architecture in the past era.

In this study, we derive an evaluation structure and 18 Valuation vocabulary for the media facade lighting conditions. In addition, this study deduced the applicable elements that could be applied in time of building nightscape lighting design using media facade by conducting affective evaluation. The research results are as follows: It was found that the image axis of "Dynamic, Colorful" showed the lighting change speed was fast with diverse application of lighting color, and its evaluation object applied by general emphasis, vertical emphasis, partial emphasis lighting method was highly assessed. In addition, it was found that "Luxurious, Unusual" axis showed lighting change speed was slow with the application of lighting color in warm hue series, and its evaluation object applied by line lighting, dot lighting, general emphasis lighting methods was highly assessed. Lastly, it was found that "Soft, Secure" image axis showed the lighting change speed was slow with the application of pastel tone lighting color, and the evaluation object applied by general emphasis lighting method was highly assessed.

This article aims to research and analyze expressional characteristics of media art in Hussein Chalayan's fashion works. Media technology has made rapid progress over every society, in which it enables multi-dimensional communication. Under this social background, media art can use a multiplicity of technologies and go public. Media art had great influences in fashion with the leading designer as Hussein Chalayan. His works has been selected from the 90s up until 2008 focusing on expressional characteristics of media art by a professional group of fashion design. By classifying and analyzing of Hussein Chalayan's fashion works, expressional characteristics of media art displayed from works of the late 90s, and in recent years, the use of various technologies has increased. Expressional characteristics of media art in his works have been re-classified as interactivity, transfonnation, visualization, and transparency. First, interactivity by the wearer's action and emotional change is effective on emotional express, body protection and the causing of interest. Second, transfonnation by the wearer's action, functioning, and emotional change is influenced by convenience, body protection, and causing concern. Third, immateriality in media art is divided into visualization and transparency, and in fashion structural and material characteristics. Visualization by internal luminous source and digital images influences immersion and expression on fantasy images. Fourth, transparency by immaterial characteristics and piled up images affects openness and camouflage. Development of material and technology paves the way for expressional characteristics of media art in fashion. The trend of Hussein Chalayan's works moves towards emotional high-tech design with technology.

The present study selected female Japanese and Korean university students (a population that is assumed to be sensitive to the subject of fashion) as subjects. We investigated (1) their awareness of and attitudes about clothing styles, and (2) their relationships to fashion and various media. In both Japan and Korea, female students were highly interested in fashion and their major motive for adopting a given fashion was "style change" (the desire to change one's style by adopting a novel fashion) or "self-expression" (the desire to express oneself and achieve self-realization). They most frequently adopted a fashion during the acceptance phase (when the fashion has spread through the market and been shown extensively by the media). Korean students were more interested in and positive to fashion than were Japanese counterparts. Fashion magazines often served as the major source of information on clothing fashions. The frequency of buying magazines and the number of magazines bought were higher in Korea than in Japan. The time spent in reading these magazines was also longer in Korea. The frequency of buying fashion magazines correlated with the degree of interest in fashion and the time when a fashion was adopted. Students who adopted a fashion earlier tended to buy fashion magazines more frequently.

Purpose: To better understand the benefits and harms of engagement with online pediatric liver disease communities within social media. Methods: We conducted a survey of caregivers of children with liver disease participating in online pediatric liver disease communities within social media, as well as a survey of healthcare providers (e.g., physicians, surgeons, nurse coordinators) from this field to better understand the perceived benefits and harms of participation. Results: Among 138 caregivers of children with liver disease that completed the survey, 97.8% agreed social media was a good place to learn about patient experiences and 88% agreed it was a good source of general information. Among caregivers, 84.8% agreed social media helps them to better advocate for their child. While 18% agreed that the information over social media was equal to the information from their healthcare team and 19% neither agreed/disagreed, only 3% indicated they would use this information to change care without telling their provider; in contrast, among 217 healthcare providers, 55% believed social media may lead caregivers to change management without telling their team. Conclusion: Engagement with online disease-specific communities in social media yields several benefits for caregivers and, in contrast to healthcare providers' concerns, participation is unlikely to lead to problems including caregivers changing the treatment plan without first discussing these plans with their team. Openness between caregivers and medical teams about the role for social media can help to improve trust and maximize the potential benefits of engagement with these groups.
