As the use of smart devices is being increased rapidly by the development of internet and IT technology, the contents production and utilization rate are showing higher increase, too. In addition, the type of contents also shows very diverse forms such as education, game, video, UCC, etc. In the meantime, the contents are reproduced in diverse forms by reprocessing the original contents, and they are being serviced through the contents service platform. Therefore, the platform to make the contents reprocessing easy and fast is needed. As the diverse contents distribution channels such as YouTube, SNS, App Service, etc, easier contents distribution platform is needed, and the development of the relevant area is expected. In addition, as the selective consumption of the contents having easy accessibility through diverse smart devices is distinguished, the demand for the platform and service that can identify the contents consumption propensity by individual is being increased. Therefore, in this study, to vitalize the online contents distribution, the contents reproduction and publishing platform, was designed and materialized, which can reproduce and distribute the contents based on the real-time contents editing technology in URL unit and the consumer propensity analysis technology using the data management-based broadcasting contents distribution metadata technology and the edited image contents streaming technology. In addition, in the results of comparing with other platforms through the experiment, the performance superiority of the suggested platform was verified. If the suggested platform is applied to the areas of education, broadcasting, press, etc, the multi-media contents can be reproduced and distributed easily, through which the vitalization of contents-related industry is expected.

The smart factory promotion project is a project that improves the entire management environment system, including the production process, using ICT technology. According to the 2019 Smart Factory Survey and Analysis Research Report of the Ministry of SMEs and Startups, small and medium-sized enterprises that introduced smart factories reported positive effects such as increased productivity, improved quality, and reduced costs on average. On the other hand, the survey results of companies that promoted the project despite positive results showed that there was room for improvement. This study dealt with the contents of the survey conducted on companies by the smart factory promotion agency in 2020 regarding the infrastructure configuration for promoting smart factories. We examined the meaningful contents implied by the data related to the infrastructure configuration. These meaningful survey results can lead to more efficient business promotion in the future when promoting smart factory projects.

There are rapidly increasing in the number of SNS users according to quick supply of smart phones and expansion of wireless internet services, but there is no much researches on hospital promotion using SNS. In this paper, we proposed methods for development of effective hospital promotion by investigating current status of homepages, mobile web contents and SNS operated in 21 dermatology hospitals located at Seoul city and by analyzing contents according to functions as hospital promotion media. In the investigation results, all of three contents such as homepage, mobile web content and SNS are opened in 76.1% of hospitals and external companies occupied the main management body of the three contents at the largest portion(56.2%). There are hospital information, clinic, reservation in all hospitals' homepages and followed by broadcasting(90.5%), medical treatment(85.7%), consultation information(80.9%), member information in 'mypage'(42.9%), staff information(14.3%). In the analysis results, there is need to enlarge departments or staffs taking full charge of in order to manage the three contents professionally and also there is need to prepare and conduct hospital promotion methods using prevalent SNS.

The personal image information compiled through closed-circuit television (CCTV) will be open to the internet with the technology such as Long-Tail, Mash-Up, Collective Intelligence, Tagging, Open Application Programming Interface (Open-API), Syndication, Podcasting and Asynchronous JavaScript and XML (AJAX). The movie User Created Contents (UCC) connected to the internet with the skill of web 2.0 has the effects of abuse and threat without precedent. The purpose of this research is to develop the institutional and technological method to reduce these effects. As a result of this research, in terms of technology this paper suggests Privacy Zone Masking, IP Filtering, Intrusion-detection System (IDS), Secure Sockets Layer (SSL), public key infrastructure (PKI), Hash and PDF Socket. While in terms of management this paper suggests Privacy Commons and Privacy Zone. Based on CCTV-UCC linked to the above network, the research regarding personal image information security is expected to aid in realizing insight and practical personal image information as a specific device in the following research.

Digital Multimedia Broadcasting (DMB) Multimedia Application Format (MAF) [3] specify how to combine the variety of DMB contents with associated information for a presentation in a well-defined format that facilitates interchange, management, editing, and presentation of the DMB contents. The current metadtata specification for DMB MAF [3] is based on TV-Anytime metadata tools. In this paper, we overview the general application scenarios of DMB MAF and then explore the TV-Anytime metadata tools and usage examples proposed for DMB MAF.

When Digital Contents goes through production${\cdot}$delivery${\cdot}$consumption, MPEG(Moving Picture Expers Group)-21 IPMP(Intellectual Property Management and Protection) defines standard which have defined by FCD(Final Committee Draft) level to keep the Digital Contents in safety. And development of system which applied to latest standard to protect and manage the broadcasting contents is required. Currently, the system to protect and manage the broadcast contents consists of fourth organizations which means production server, tool server, license server, consumption server. In this paper, we made production server to parse REL(Right Expression Language) document that has right information for content from license server, and create metadata based on MPEG-21 IPMP about the content that applied to watermark. then, after it do remuxing, transmit the protected data to consumption server.

This paper presents our performance evaluation after the way of minimizing waiting times between channel switching for eMBMS(evolved Multimedia Broadcast/Multicast Services) technique in LTE-Advanced systems. Existing composition of MBMS using IGMP(Internet Group Management Protocol) transfers the data with Multicast from BM-SC(Broadcast Multicast Service Center) to eNB(evolevd Node B) and with Broadcast from eNB to UE(User Equipment). Therefore, in case of channel switching, IGMP Join report should be transferred to BM-SC and then wait user's contents to be retransferred from eNB. To achieve this, Subscriber Channel technique of priorities is used for minimizing waiting times between channel switching as UE broadcasts favorite channels in advance.
