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.

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.

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.

Background: Due to the declining number of students preparing for university entrance exams , the quota of universities has been decreasing continuously. This situation became increasingly diverse as new media used online, mobile, and PR tools to continuously invite students. This study is aimed at offering the helpful data to plan an effective PR strategy by analyzing the correlation between the major selection and satisfaction of the department's social media usage among freshmen majoring in dental hygiene. Methods: The collected data from the self-reported survey with freshmen were analyzed using the SPSS 22.0 program. The survey items were motive to select the major, social media platform that subjects used, reasons to use the media, time to visit the department's social media platform, and satisfaction level on the department's social media platform, using a 5-point Likert Scale. Results: The reasons for choosing a major were given by 32.2% and 15.9% respondents, respectively, as the vision after graduation and practice facilities. 39.9% and 31.4% used Instagram and YouTube for social media platforms, respectively, for using social media platform; 26.9% and 26.3% visited the department's social media before and after entering the university, respectively; 46.4% and 24.9% used Instagram and YouTube for department social media; and they generally satisfied with the contents of the department's social media. 40.9% of them said that information from the department's social media was useful. 33.8% of them said the information from the department's social media exceeded their expectations. 46.8% of them answered that the department's social media made the department's image positive. 33.4% got interested in the major more due to the department's social media. According to 32.1% of respondents, the department's social media was helpful in deciding on a major. With 35.4%, a positive correlation was discovered between the department's practice facilities and satisfaction on the department's social media. Conclusion: It is thought that the department's social media should try continuously by uploading the contents to meet the users' needs on a regular basis and seeking the plans to be able to collect various opinions using surveys through the related social media so that students can select the major and, moreover, lead the positive direction to adapt the university life under the unfamiliar environment after admission.

Objective: To evaluate the pancreatic differentiation potential of α-1,3-galactosyltransferase knockout (GalTKO) pig-derived bone marrow-derived mesenchymal stem cells (BM-MSCs) using epigenetic modifiers with different pancreatic induction media. Methods: The BM-MSCs have been differentiated into pancreatic β-like cells by inducing the overexpression of key transcription regulatory factors or by exposure to specific soluble inducers/small molecules. In this study, we evaluated the pancreatic differentiation of GalTKO pig-derived BM-MSCs using epigenetic modifiers, 5-azacytidine (5-Aza) and valproic acid (VPA), and two types of pancreatic induction media - advanced Dulbecco's modified Eagle's medium (ADMEM)-based and N2B27-based media. GalTKO BM-MSCs were treated with pancreatic induction media and the expression of pancreas-islets-specific markers was evaluated by real-time quantitative polymerase chain reaction, Western blotting, and immunofluorescence. Morphological changes and changes in the 5'-C-phosphate-G-3' (CpG) island methylation patterns were also evaluated. Results: The expression of the pluripotent marker (POU class 5 homeobox 1 [OCT4]) was upregulated upon exposure to 5-Aza and/or VPA. GalTKO BM-MSCs showed increased expression of neurogenic differentiation 1 in the ADMEM-based (5-Aza) media, while the expression of NK6 homeobox 1 was elevated in cells induced with the N2B27-based (5-Aza) media. Moreover, the morphological transition and formation of islets-like cellular clusters were also prominent in the cells induced with the N2B27-based media with 5-Aza. The higher insulin expression revealed the augmented trans-differentiation ability of GalTKO BM-MSCs into pancreatic β-like cells in the N2B27-based media than in the ADMEM-based media. Conclusion: 5-Aza treated GalTKO BM-MSCs showed an enhanced demethylation pattern in the second CpG island of the OCT4 promoter region compared to that in the GalTKO BM-MSCs. The exposure of GalTKO pig-derived BM-MSCs to the N2B27-based microenvironment can significantly enhance their trans-differentiation ability into pancreatic β-like cells.
