In the smart media environment, magazine industry has been experiencing a transition to ecosystem of value network, which includes high complexity and ambiguity. Using case study method, this article conducts research on digital convergence, the model of magazine ecosystem and adaptation strategy of global magazine companies. Research findings have it that the way of contents production of global magazines has been based on collaborative production system within communities, expert communities, creative users, media contents companies and magazine platform. The system shows different patterns and characteristics depending on magazine-driven platform, Platform-driven platform or user-driven platform. Collaboration system has been confirmed in various cases: Huffington Post and Zinio which collaborate with media contents companies, Amazon magazines and Bookish with magazine companies, Huffington Post and Wired with expert communities, and Flipboard with creative users and communities. Foreign magazine contents diverge into (paper, electronic, app and web magazine) as they start the lively trades of their contents on the magazine platform. In the area of contents uses, readers employ smart media technology effectively such as cloud computing, artificial intelligence and module individualization, making it possible for the virtuous cycle to remain in the relationship within communities, expert communities and creative users.

This study proposes a CMS platform for AR-based remote collaboration in a smart factory. The Smart Factory site utilizes various forms of AR technology to save time and money. As the level of smart factory increases, system-oriented tasks such as machinery and equipment are performed in people-oriented work. Therefore, there is a need for a system that allows the operator to immediately repair the machine or equipment in case of a failure, or to get help if necessary. Remote collaborative CMS platform is designed to work in conjunction with DATABASE of ERP, MES / POP, and PLM system built through text, 2D 3D contents and smart factory business, This study is meaningful in that it saves time and cost by sharing information such as management, repair method, manual, etc., and repairing it quickly.

가상화 기술의 등장으로 서버를 가상화하여 컴퓨팅 자원을 동적으로 사용할 수 있게 되면서 탄력적인 프로비져닝이 가능해져 기업은 좀 더 유연하게 대처할 수 있게 되었다. 클라우드 컴퓨팅 환경을 이용하는 데 있어 가장 중요한 이슈 중 하나는 자원을 사용함에 있어 실제 필요한 양만큼 할당하여 사용하는 것이다. 현대 응용의 가변적인 작업 부하에 따라 필요한 만큼만 자원을 제공하기 위해 SLA 기반 오토-스케일링 기법을 이용하여 자원 할당의 자동화를 연구하고 있다. 하지만 대부분의 클라우드 협업 플랫폼은 오토-스케일링 기술을 지원하지 않는다. 또한, 대부분의 SLA 기반 오토-스케일링 기법은 웹 응용에서 중요한 평균 응답 시간은 보장하지 않는다. 본 논문에서는 클라우드 환경에서 가변적인 사용자 요청에 따라 플랫폼은 평균 응답 시간을 보장하고 SLA 위반 여부에 따라 추가 자원을 할당하는 오토-스케일링 기법을 제안한다.

In this paper, a platform of portable cultural assets surveillance system is designed in order to prevent the theft of cultural assets. The platform was designed to take into account the characteristics of the cultural assets for minimizing of the damage of cultural assets. The platform is composed of the portable cultural assets surveillance system and the collaboration network protocol among th surveillance system. If an intruder steals the cultural assets and moves according to the scheduled route, it is expected that the platform has a great role because the platform of portable cultural assets surveillance system can performs the continuous tracking by the collaboration network.

This paper presents an IoT platform of common interfaces that are flexible IoT applications and Connect the smart devices. The IoT platform includes automatic collaboration discovery the smart Device. It is different things case with connection each device through IoT Platforms are each device and application service. Due to these heterogeneities, it is quite advantages to develop applications working with derived IoT services. This circumstance needs the generic interface and results in a range of IoT architectures by not only the environments settings and discovery resource but also varied uniqe to implementation services working with IoT applications. Therefore, this suggestion of solve the problems and make it possible independent platforms always alive to connection with each devices based on the generic interface. The generic interface is heterogeneity-driven solve the problems and effectively contributions a platform that could be operated in diverse IoT Platforms.
