Media company is not a business which sells news and information but a company sells audience's attention. Advertisers estimate audience's quantity and quality which pay attention to media and pay the cost. Thus drawing audience's attention is a natural and instinctive behavior for survival of media company. News doesn't deliver the fact just as it. That's impossible. News is a commodity made by processing and selection of the media company and journalist. On the process, judge of values is involved and limitation of time and place of media is considered. If scientists understand media's character truly, their misunderstanding about media company and journalist may be cleared up. In this society, media is not a being to ignore, particularly for big science like space science which spends huge public capital. Nowadays, space science meets the time to take the leap in Korea. However that can be crisis cause of uncertainty of science activity. When the crisis which no one desires happens, preparation needs for new opportunity. We can take the crisis as a chance. Understanding about media and public will be the first step for this preparation.

This paper intends to explore the social and cultural implications of convergence media, based on Goffman's situational approach. The situational segregation of regions makes us to re-interpret the current private and public spheres and helps us to reveal the principle and structure hidden in the new middle region. An environment of convergence media is nullifying the separation of private and public spheres, while letting a new middle region appear.

In this paper we present an algorithm to generate new views of a scene, starting with images from weakly calibrated cameras. Errors in 3D scene reconstruction usually gets reflected in the quality of the new scene generated, so we seek a direct method for reprojection. In this paper, we use the knowledge of dense point matches and their affine coordinate values to estimate the corresponding affine coordinate values in the new scene. We borrow ideas from the object recognition literature, and extend them significantly to solve the problem of reprojection. Unlike the epipolar line intersection algorithms for reprojection which requires at least eight matched points across three images, we need only five matched points. The theory of reprojection is used with hardware based rendering to achieve fast rendering. We demonstrate our results of novel view generation from stereopairs for arbitrary locations of the virtual camera.

This paper describes a CMOS outphasing transmitter using two wideband phase modulators. The proposed architecture can simplify the overall outphasing transmitter architecture using two-point phase modulation in phase-locked loop, which eliminates the necessity digital-to-analog converters, filters, and mixers. This architecture is verified with a WCDMA signal at 1.65 GHz. The prototype is fabricated in standard 130 nm CMOS technology. The measurement results satisfied the spectrum mask and 4.9% EVM performance.

Recently there are so many media contents created and used by variety routes. Therefore, it is essential to make a new platform which is used for distributing media contents include IPTV. With open IPTV service, developing the new platform became even more important. Because open IPTV makes it possible for consumers to choose contents regardless of contents of the providers. The new platform has to accept current variety service structure. MPEG-21 multimedia framework was developed to satisfy these needs. It presented the distribution framework of the contents but didn't restrict the particular solutions for protecting the rights. In this paper, we present authoring and consuming system for package contents based on MPEG-21 Multimedia Framework for distributing media resources and managing the license of multimedia contents

소니피케이션은 다양한 데이터를 사운드로 변환시키는 과정으로 본 연구에서는 뇌파 신호를 사운드로 생성하는 객관적인 워크플로우를 제시하고자 하였다. 현재까지의 뇌파 소니피케이션은 사운드로의 변환이 인위적이고 임의적으로 진행되어 객관적인 논리를 제시하지 못하고 있는 실정이다. 이에 본 연구에서는 뇌파데이터의 정량적 분석을 통해 파라미터 추출, 사운드 맵핑, 사운드 모델 구축에 대한 논리적 근거를 제시하였으며 이를 통해 뇌파데이터의 객관적인 소니피케이션 과정을 구현하였다. 파라미터 추출을 위해 15Hz High pass filtering이 가장 적절한 방법으로 확인되었으며 뇌파 데이터의 최대값 빈도 분석과 음악코드의 비율 분석을 실제로 맵핑시켜 사운드 모델을 구축하여 사운드 생성을 구현하였다. 결론적으로, 본 연구에서는 뇌파데이터의 소니피케이션 과정에 대한 객관적이고 논리적인 워크플로우를 제시하였으며 이러한 워크플로우가 다양한 분야에서 적용될 수 있을 것으로 예상된다.

일반적인 터치스크린을 이용한 입력방법인 스크린을 보고 대응하는 영역을 터치하여 숫자, 한글, 영문, 기호 등을 입력하는 방식은 시각장애인이 사용하기에는 특수한 가이드가 제공되지 않는 한 사용이 거의 불가능하다고 할 수 있다. 특히 음성과 촉감을 이용하여 해당 버튼을 찾아 이용하던 기존의 입력 방식이 아닌 평평한 터치스크린 입력 방식은 눈으로 보지 않고는 정확한 입력영역을 구분 할 수 없다. 본 논문 에서는 기존의 시각장애인을 위한 제품과 기술들의 단점을 보완할 수 있고 시각장애인들도 쉽고 정확하게 스마트 기기를 사용할 수 있는 가상 터치 키패드 입력 방식을 제안한다. 제안하는 방법은 단순한 기준점과 방향점을 이용한 터치 및 드래그 방식의 가상 키패드 정의 방식으로 터치 스크린 방식의 다양한 스마트 기기에 효과적으로 적용될 수 있다.

The new mobile edge network architecture has been required for an increasing amount of traffic, quality requirements, advanced driver assistance system for autonomous driving and new cloud computing demands on highway. This article proposes a hierarchical cloud computing architecture to enhance performance by using adaptive data load distribution for buses that play the role of edge computing server. A vehicular dynamic cloud is based on wireless architecture including Wireless Local Area Network and Long Term Evolution Advanced communication is used for data transmission between moving buses and cars. The main advantages of the proposed architecture include both a reduction of data loading for top layer cloud server and effective data distribution on traffic jam highway where moving vehicles require video on demand (VOD) services from server. Through the description of real environment based on NS-2 network simulation, we conducted experiments to validate the proposed new architecture. Moreover, we show the feasibility and effectiveness for the connected car media service on highway.

The convergence paradigm that appears with the integrated media environment has effect on digital storytelling using digital technology, then 'Trans-media storytelling' which is a new form of digital storytelling makes gradual expand its scope. This study focused on the Alternative Reality Game which adopt trans-media storytelling in the game genre. This paper interpreted the idea of ARG on comparing different forms of ARG and existing games and the distinctive features of ARG storytelling which is blurring the line between real and virtual on the Simulation theory. This is a valuable study for understanding the new storytelling form within the media convergence and developing the digital storytelling in the future.

This study drew the reason of the limitation in low-carbon city plan from a absence of 'social sustainability' and supplemented its limitation by suggesting the new concept of city facility called Green Media. It clarified the concept of Green Media, and analyzed its effect on low-carbon city plan based on the analysis of related cases inside and outside the country. This study made an important step forward in introducing the new concept to complement social sustainability, analyzing its effect, and suggesting the applicable details.
