Purpose This study aims to measure the effects of media literacy education through the social science method and find out the impact of media literacy education on digital citizenship in Korea and its implications for the development of democracy. Design/methodology/approach This study used an independent t-test to analyze relativeness between media literacy education and media literacy factors. We also adopted an independent t-test to investigate media literacy influence on digital citizenship. Furthermore, we found out age differences using 'the one-way analysis of variance (the one-way ANOVA)'. Findings We have found four media literacy factors, MC, CT, C&P, R&R, have been significantly affected by media literacy education. We have also pulled out three digital citizenship factors, IPA, TS, and CP, involved in media literacy education. Moreover, we have analyzed our survey by different age groups. The lower the age, the higher the TS. CP was highest among those from 30 to 59, followed by those under the 30s.

To interactively share High Definition (HD)-quality visualization over emerging ultra-high-speed network infrastructure, several lossless and low-delay real-time media (i.e., uncompressed HD video and audio) transport systems are being designed and prototyped. However, most of them still rely on expensive hardware components. As an effort to reduce the building cost of system, in this paper, we propose the integration of both transmitter and receiver machines into a single bi-directional transport system. After detailed bottleneck analysis and subsequent refinements of embedded software components, the proposed integration can provide Real-time Transport Protocol (RTP)-based bi-directional transport of uncompressed HD video and audio from a single machine. We also explain how to interface the Gbps-bandwidth display output of uncompressed HD media system to the networked tiled display of 10240 $\times$ 3200 super-high-resolution. Finally, to verify the feasibility of proposed integration, several prototype systems are built and evaluated by operating them in several different experiment scenarios.

Media diversity, coupled with the logic of competition in the global media market, has become a fashionable yet unfitting lingo of media policy in Korea. Media diversity has been fenced in the neoliberal economic logic of market competition and so tamed to consumers' free choice in the market. It is within this context that this article attempts to problematize narrowly-defined, market-oriented, and measurement-obssessed funtionalistic approaches to media diversity. In doing so, the article provides a critical overview of various definitions of media diversity. It also reveals how certain definitions, justifications, and measurements are legitimized and normalized in the name of science and objectivity. The core argument is that reflecting a larger neoliberal, deregulatory turn in media policy, media diversity has shifted from the pluralistic principle of democracy to the matter of free market choice or the myth thereof. It then focuses on the ongoing debate between state interventionists and free market liberals over the relationship between media ownership concentration and content diversity. Finally, it puts forth some recommendations as to how media diversity ought to be reconsidered as reformers' cultural politics, rather than marketeers' science, and discusses implications diversity has for deepening Korean democracy.

This study was performed to get the basic information concerned to the optimum culture condition of Inonotus obliquus. Several solid media, PDA, MEA and Czapek-Dox, and three liquid media were adopted for the in vitro cultivation. Some main features of the fungal morphological characteristics under cultivation conditions were observed and described. Preliminary results showed that appearance of the mycelial mat, hyphal size and substrate pigmentation differed according to the media. The PDA medium was the most favorable substrate for the growth on solid culture, followed by MEA and Czapek-Dox media. Concerned to the addition of amino acids, 5 amino acids, such as alanine, alginine, isoleucine, leucine and threonine, enhanced to the mycelial growth. Isoleucine was shown the best fungal growth. An important morphological hyphal structure for the fungus, the setae, was found in abundance and diverse its shape and size. In liquid culture, fresh potato broth was the best growth stimulant of the fungus, followed by Malt extract and potato broth. Addition of yeast extract to the liquid media had improved the biomass, but not laccase production.

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.

This paper examines the effects on academic achievement, scientific process skills and affective domain for elementary students learning the 'Chicken life cycle' through traditional science class versus a smart media based STEAM approach. Students designed and built a hatching jar and created a smart media content for chickens using time-lapse technology. This STEAM program was developed to improve their scientific concepts of animals over nine periods of classes using integrated education methods. The experimental study took place in the third grade of public schools in a province, with the STEAM approach applied in 2 classes (44 students) and the traditional discipline approach implemented in 2 classes (46 students). The STEAM education significantly influenced the improvement of academic achievements, basic scientific process skills and affective domain. The results suggest that this STEAM approach for teaching scientific concepts of animal life cycles has the performance in terms of knowledge, skills and affect gain achievements in elementary school students' learning when compared to a traditional approach. Moreover, the smart media based STEAM program is helpful to lead students to engage in integrated problem-solving designs and learning science and technology.

가상현실과 증강현실의 대중화로 사람의 동작을 실시간 3D 애니메이션으로 구현하는 연구가 활발히 진행 중이다. 특히 Microsoft에서 키넥트 (Kinect)를 개발함에 따라 저렴한 가격에 부가적인 장치 필요 없이 간단한 조작만으로도 3D 모션 정보 취득이 가능해졌다. 하지만 키넥트 카메라는 마커 기반 모션 캡쳐 시스템에 비해 관절 정보의 추정 성능이 뒤떨어져 낮은 정확도를 보이는 단점을 지니고 있다. 이에 본 논문에서는 키넥트 카메라를 이용해 사람의 관절 정보를 취득하고 이것에 관절 가동 범위 (Range of Motion, ROM)를 적용하여 비정상적인 동작을 보정하는 시스템을 제안한다. ROM을 구하는 방법으로는 수행자가 모든 관절에 대해 회전 운동을 수행한 뒤 관절들의 회전 운동 정보를 취득, 분석하여 정상적인 ROM을 설정하고 실험으로부터 사람의 동작이 개선되는 것을 확인하였다.

In museums, exhibition content focuses mostly on cultural heritage's historical values and functions, but doing so tends to limit visitors' interest and immersion. To counter this limitation, the study developed an experiential media art exhibition fusing bronze mirrors' traditional production technology and modern conservation science. First, for the exhibition system, scientific cultural heritage contents were projected on the three-dimensional (3D) printed bronze mirror through interactions between motion recognition digital information display (DID) and the projector. Then, a scenario of 17 missions in four stages (production process, corrosion mechanism, scientific analysis and diagnosis, and conservation treatment and restoration) was prepared according to the temporal spectrum. Additionally, various media art effects and interaction technologies were developed, so visitors could understand and become immersed in bronze mirrors' scientific content. A user test was evaluated through the living lab, reflecting generally high levels of satisfaction (90.2 points). Qualitative evaluation was generally positive, with comments such as "easy to understand and useful as the esoteric science exhibition was combined with media art" (16.7%), "wonderful and interesting" (11.7%), and "firsthand experience was good" (9.2%). By combining an esoteric science exhibition centered on principles and theories with visual media art and by developing an immersive directing method to provide high-level exhibition technology, the exhibition induced visitors' active participation. This exhibition's content can become an important platform for expanding universal museum exhibitions on archaeology, history, and art into conservation science.
