위성정보 데이터는 지구를 관측하여 수집한 데이터로 국방, 자연재해, 위치기반 서비스, 인프라, 환경, 에너지, 해양, 보험 등의 다양한 분야에서 활용되고 있다. 본 연구는 위성정보 활용 사업의 선순환 구조와 산업의 비즈니스 생태계 모델을 제시하는 것을 목적으로 한다. 연구방법으로 문헌, 온라인, 어플리케이션, 콘텐츠 등의 영역에서 사례를 수집하고 분석하였다. 사례를 살펴본 결과 공공 및 상업 영역에서의 콘텐츠 서비스에 관한 비즈니스 모델을 제시하고 있었으며, 복합 범용 기술 차원에서 콘텐츠 제작과 서비스를 용이하게 하는 다양한 알고리즘 기술을 개발하고 있었다. 둘째, 위성정보 데이터의 콘텐츠 유형화 차원에서 생태환경 모니터링 콘텐츠, 도시공간 모니터링 콘텐츠, 위성정보 기반 게임 콘텐츠로 세분화할 수 있었다. 셋째, 위성정보 기반의 콘텐츠가 사용자에게 제안하는 콘텐츠의 가치를 정보적 가치, Environmental, Social, and Governance (ESG) 가치, 교육적 가치, 콘텐츠적 가치 등으로 세분화할 수 있었다. 연구 결과로 위성정보 활용 사업의 전개 과정을 시각적으로 도식화한 생태계 모델과 콘텐츠 발굴의 유형화 방안을 제시하고 있다. 더 나아가 위성정보 데이터의 대중화 및 접근성을 높이는 콘텐츠 창출의 다양한 방안을 모색하고, 정부의 투자 확대, 인력 양성, 법적 제도 구축 등을 토대로 한국형 K-위성정보 활용 사업의 생태계 모델을 모색해야 한다는 제언을 하고 있다.

With the development of artificial intelligence (AI) and 5G technology, an ecosystem of digital content is gradually becoming intelligent, immersive, and convergent. However, there is not enough ultra-realistic content for the ecosystem. For ultra-realistic content services, creative content technologies using AI are being developed. This paper introduces the trends in and prospects of creative content technologies such as 3D content creation, digital holography, image-based motion recognition, content analysis/understanding/searching, sport AI, and content distribution.

The diffusion of smart devices has greatly influenced the market dynamics of the telecommunications industry. The competition paradigm has shifted from individual firm-based competition to ecosystem-based competition. To satisfy the diverse needs of market customers, it has become more important for telecommunications companies to form alliances with complementary partners in the ecosystem. This study empirically investigates the influence of ecosystem-based alliance formations on the financial performance of firms in the Korean telecommunications market. Specifically, the impact of a CPND (Content, Platforms, Networks, and Devices) alliance in the ICT (Information and Communications Technology) sector on firms' profitability is examined using a structural equation model. The results indicate that before the diffusion of smart devices, ecosystem-based alliance formations with other firms in the ICT ecosystem were not effective for enhancing profitability. However, after this diffusion, alliance formation between members of the value chain in the ICT ecosystem contributed significantly to firms' financial performance. This implies that recent alliances with firms that are constituents of the ICT ecosystem are an important element of profit generation in the ICT market in Korea.

In 2006 and 2007, there was a big outbreak of the Ussur Brown Katydid, Paratlanticus ussurriensis in the central part of Korea attacking some orchard trees. Until 2000, the katydid had not been regarded as an agricultural pest because they were distributed widely in Korea with low population density and their habitats were confined mainly to hillsides of forested areas. The fact that katydid attacked orchard trees with a higher population density seemed to be related to a change in feeding environment. And the shift of their habitats from oak woodlands to commercial orchards was thought to be related to the nutritional contents of their feed. In an attempt to understand these relationships, we conducted an ecological study of the affected areas. When the katydids changed their habitats in early May of 2008 and 2009, they shifted their host plants from oak trees to peach trees. The habitat shift was closely related to the nitrogen (N) content of the host plant leaves. When katydid moved to the hillside adjacent to orchard farm, N content of oak tree leaves decreased dramatically from 5.3% to 2.2%. At that time N content of peach tree leaves were higher than the 2.2% of oak leaves, showing 3.5~5.0%. This range of N content of peach tree leaves has been consistent until late June. And feed preference analysis carried out in the laboratory showed that katydid prefered peach tree leaves to peach fruit to oak tree leaves.

4차 산업혁명의 한 분야로 각광받고 있는 가상현실의 성장이 예측과는 다르게 지연되고 있다. 본 연구에서는 이러한 이유를 간략하게 콘텐츠-플랫폼-네트워크-디바이스 (C-P-N-D)생태계 관점에서 분석해 보았다. 가상현실은 사용자가 디바이스를 착용하고 네트워크를 통해 플랫폼에 접속하여 다양한 콘텐츠를 이용하는 기술이다. 따라서 가상현실의 성공적인 대중화를 위해서는 C-P-N-D 생태계 분야들의 균형적인 육성이 중요하다. 우리나라는 네트워크를 제외한 콘텐츠, 플랫폼, 디바이스 모두 경쟁력이 낮은 수준으로 평가받고 있다. 개별 분야에 대한 경쟁력 확보 노력도 중요하겠지만, 킬러 콘텐츠를 활용할 수 있는 네트워크 기반 플랫폼의 육성이 더욱 필요하다. 단순한 킬러 콘텐츠의 육성만으로는 전체 가상현실 C-P-N-D 생태계를 구축할 수 없음을 명심해야 할 것이고, 방송/미디어 분야도 이러한 접근이 필요함을 주지해야 할 것이다.

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.

We derived a length-weight relationship for Calanus sinicus off Busan, Korea in spring to estimate the biomass of the C. sinicus population around Korean waters, and compared it with the previously derived equations. The developmental stages and prosome length of C. sinicus used in the relationship ranged from 1,376-1,540 ㎛ for copepodite 4 (CIV), 1,753-1,971 ㎛ for copepodite 5 (CV), and 2,160-2,283 ㎛ for adults (CVI). Dry weight and carbon content were measured from a total of 26 replicates. Length-weight relationships derived in the present study are as follows: log C = 3.342 log PL - 9.449, log DW = 3.394 log PL -9.219, where C is carbon content (㎍), DW is dry weight (㎍), and PL is prosome length (㎛). When comparing the present regression equation of length-weight for C. sinicus with the previous one, our regression equation showed an average carbon estimate to a given range of mean prosome length. The length-weight relationship of C. sinicus in the present study can be used to better estimate the biomass of the C. sinicus population in the coastal waters of Korea.

These days a great mix of traditional and digital contents such as movie, broadcasting, advertisement, e-books, music, game, animation, cartoon, character, knowledge information, and art performance are widely available. Many more are yet to come, with improved quality and added features. It is expected that all these contents will be evolved into a new breed of convergence content through the process of consolidation, expansion, integration, and recreation. Across the digital ecosystem, a new formula is being added to the industrial structure : 'Information/Content-Platform/Device-Goods/Service.' In the near future, as a result of technological innovation and convergence, the business sector will lose its boundaries as well, as businesses will be forced to look beyond the product itself and focus more on multi-functionality. Especially, in the era of creative economy, more policies need to be crafted in order to procure a new growth engine for the future with the agenda for convergence between humanities and technology. Therefore, the purpose of this paper is to analyze the concept, factors, elements, types, and cases of convergence, which are the essence of content convergence. This analysis, with its focus on the convergence process, will help identify the effects and limits of content convergence as well as the prospects for convergence contents in the smart ecosystem under the creative economic system.

Recently, discussions on Metaverse, which represents the transcendent world, have been dominant for some time. Cases related to the Metaverse are introduced through various media and are continuously attracting attention as the next generation of the Internet. This study reviews the business model and the ecosystem overview, focusing on service cases related to the Metaverse. The widely used business models include content production and sales, media brokerage fee, and marketing fee. The Metaverse ecosystem is formed around games, with major players in game production, authoring tool & support SW, intelligent cloud service, and game platform expected to lead the market. Results show that a strategy to secure the leadership of the Metaverse, such as the business model expansion conditions, a strategy to foster a game-oriented Metaverse ecosystem, and technology development for the realization of the ultra-realistic Metaverse, is necessary.
