This paper examine the changing ecosystems in Malaysia, starting with the government policy driven greenfield cluster of Cyberjaya, which is part of the Multimedia Super Corridor (MSC) mega project. In this context of an emerging economy, predominantly production oriented, the role of the government was crucial with respect to implementing policies and building infrastructure for the ecosystems. First, the roles played by the cluster development agency, universities, and industry are explained. As the cluster developed, this paper, taking an entrepreneurial ecosystem approach, explores how some actors evolved and changed their roles to become catalyst organisations established for the cluster now serving nationwide. This was followed by the emergence of new actors in the ecosystems, for example, knowledge intermediaries, and new roles for universities. In addition to actors such as universities and industry, this paper recognizes the emergence of media organisations as new actors in the entrepreneurial ecosystems in Malaysia.

실험실 내에서의 해양 선충류 최적 배양 조건을 찾기 위해 한천배지로 다양한 배지를 제작하여 선충류를 대상으로 한 연구를 수행하였다. 선충류 채집은 태안 만리포 조간대 중 하부의 사질 퇴적물 표층에서부터 약 5 cm의 퇴적물에서 이루어졌다. 배양에 이용한 한천 배지는 Killian 배지의 조성을 다소 변형하고, 한천 농도에 차이를 두었으며, 이 한천배지들을 직경 60 mm 페트리디쉬에 배지 높이가 2.0 mm가 되도록 분주하였다. 선충류의 먹이 생물로서 순수 배양한 미생물 5종을 혼합하여 각각의 배지에 첨가하였다. 각 배지에 Enoplolaimus sp. 5개체를 접종하여 $20^{\circ}C$, 암배양으로 설정된 배양기 내에서 배양하였다. Enoplolaimus sp.에 대하여 여러 조건의 실험을 반복 수행한 결과, Killian 배지에 소고기 육즙만을 첨가한 배지의 한천농도 1.0%에서 평균 생존시간이 246.8시간으로 가장 높은 생존율을 나타냈다. 가장 낮은 생존시간은 Killian 배지에 bacto peptone과 소고기 육즙(beef extract)을 첨가한 한천농도 0.4%의 먹이 공급을 한 배지에서 평균 27.6시간으로 가장 낮은 생존시간을 나타냈다. Bathylaimus sp.는 Killian 배지 한천농도 1.0%의 먹이 공급을 하지 않은 배지에서 가장 높은 생존시간을 나타내었고, 산란량과 부화율 실험에서는 평균 7개의 알을 산란하였으며 평균 99.5시간 후에 94.7%의 부화율을 보이는 결과를 나타냈다

Artificial intelligence (AI) has become the hottest topic in information and communications technology (ICT) in recent years. Along with the advancement of AI technology, technologies such as big data, cloud, and high-speed wired and wireless communication are being applied to existing media areas in earnest, affecting all parts of the media value chain from content production to consumption. AI technology is now spreading across the media industry faster than any other industry. In the future, the gap between those with and without AI technology will widen, further deepening the polarization of the media ecosystem. Media intelligence, which combines media and AI technologies, is now perceived as essential, not optional. In this paper, we examine the current status of technology development and standardization by major domestic and foreign institutions on how AI is being utilized in the media industry. In addition, we discuss what technology should be developed to lead media intelligence.

This study examined the effects of reflective writing activities utilizing environmental related mass media. Two classes participated as an experimental group (n=31) and a control group (n=30). Both groups of students learned five different topics on environment, such as diversity of ecosystem, global warming, desertification, reduction of the amount of carbon, and eco-friendly behavior. The experimental group students was taught utilizing mass media about each topic and had opportunities of reflective writing about each topic, while the control group of students was taught through lectures. The results indicated that students in the experimental group represented significantly better scores on environmental worldview, environmental sensitivity, and eco-friendly behavior compared to the control group students (p<.01).

본 연구는 2013년부터 정부가 추진하고 있는 상상콘텐츠기금 논의의 문제를 확인하고, 디지털 환경에서의 콘텐츠 진흥기금 목적 및 부담 주체를 제시하고자 설계되었다. 본 연구는 프랑스의 새로운 콘텐츠 기금도입 정책과, 부가가치가 콘텐츠 유통 사업자들에게 집중되는 디지털 콘텐츠 생태계의 불균형 문제에 주목하였다. 공존과 균형을 통한 공진화는 생태계의 발전의 필수 요소인 바, 새로운 콘텐츠 기금의 목적은 '콘텐츠 생산 재원조달 활성화와 콘텐츠 산업의 디지털화'에 초점을 맞추어야 하며, 기금 재원은 콘텐츠 유통을 통해 부가가치를 창출하는 디지털 콘텐츠 서비스 사업자 및 스마트 기기 사업자의 역할 분담을 통해 조성되는 것이 바람직하다.

YouTube, the online video streaming platform, has become popular and influential around the globe. Due to the development of science and technology, people without expertise in filming can now easily produce their videos with unique content. Many people are more eager to become a popular YouTube creator because they can earn money by placing commercials or Products in Placement (PPL) in their video clips. However, it is yet unknown what genres of YouTube videos are popular. YouTube creators have their channels where they upload videos of a certain type of genre. This study investigates video genres of the top 250 YouTube channels in English-speaking countries (United States, Canada, United Kingdom, and Australia) using Social Blade, which is a research website. The ranking is set based on the number of times people watched a video ("Video Views"). We handsomely analyze popular genres of the channels and also the YouTube ecosystem, and it will be meaningful for today's new media era.

The microbial diversity in soil ecosystems is higher than in any other microbial ecosystem. The majority of soil microorganisms has not been characterized, because the dominant members have not been readily culturable on standard cultivation media; therefore, the soil ecosystem is a great reservoir for the discovery of novel microbial enzymes and bioactivities. The soil metagenome, the collective microbial genome, could be cloned and sequenced directly from soils to search for novel microbial resources. This review summarizes the microbial diversity in soils and the efforts to search for microbial resources from the soil metagenome, with more emphasis on the potential of bioprospecting metagenomics and recent discoveries.

The aim of this study is to formulate a trust-based business model of Internet services in so called the "trust economy." For it, firstly concepts of trust and trust economy are discussed. Then, we present previous literatures' review of trust in social science prism and trust economy in economic prism. This study classified the literatures' stances with two viewpoints of the 'system' and the 'user'. With this backdrop, we discuss three contradictory stances: Internal optimization vs. external interaction, personal data control vs. orchestration, and end-user vs. ecosystem value. In the result, we formulate a trust-based business model framework with three trust issues in user perspective and suggests three strategic directions related three issues along with representative use cases.

Underwater communication is necessarily useful for various application domains such as saving of human lives from underwater disasters, marine resource exploration, underwater military fields, underwater environment or ecosystem monitoring, fish farm monitoring and management, etc. Even though the acoustic wave has been the main underwater communication media until now, several media such as optical waves, VLF/ELF waves, magnetic fields, and infrared rays also began to be treated as possible media for underwater communication. If these underwater communicate-possible media are used mixing together, the underwater communication can be much more reliable and efficient through complementing the disadvantages of each communication media with advantages of other communication media. In fact, mixing and using multi-media for underwater communication requires the data flow control in the connection process of different media due to their communication speed gaps and bandwidth differences, and, specially, in the flow control, the appropriate message fragmentation technique is required inevitably. For this reason, this paper presents a fragmentation framework and technique necessary to the flow control in the underwater multi-media communication. In addition, through its implementation and experiments, this paper shows the feasibility on the realization of the multi-media based underwater communication.
