  • After the efficiency of H.264 video compression has been announced, it replaced MPEG-2 standard in several applications. So transcoding methods of MPEG-2 to H.264 have been studying because there are variety devices and contents followed by MPEG-2. Although H.264 supported various service such as IPTV, DMB, digital broadcasting etc, but users using MPEG-2 devices cannot accessible to them. This paper propose H.264 to MPEG-2 transcoding for users of MPEG-2 devices without displacement H.264. The proposed method predicted a motion vector for MPEG-2 encoder after it extracted from motion vectors of variable blocks in H.264 to improve processing time. Also it predicted a optimal motion vector using modified boundary matching algorithm after grasped a special character for boundary and background of object. The experimental results from proposed method show a considerable reduction in processing time, as much as 68% averagely, with a small objective quality reduction in PSNR.

  • Feature of current IPTV services is that the IPTV Provider buys the rights of contents from contents author and provides consumers monopolistically with those. In this environment, IPTV is indistinguishable from the way of existing broadcasting services. To shift away from this structure, it is necessary to guarantee the common user's participation and provide the Open IPTV services for customers to be allowed to have be defined for more opportunities to select the contents. However, there are some problems to conduct Open IPTV service due to a variety of rights protection solutions designed by previous digital broadcast providers. Therefore, a new framework is needed to overall Open IPTV environment. This paper provides the design can packaging contents authoring and consuming tool for IPTV application service based on Open IPTV.

  • A community-centered smart village process model was developed through the theoretical review of the rural field forum. By analyzing the difference in technology demand according to the digital capabilities of leaders by community type, village types were classified and detailed technologies were defined. The smart village process was proposed to enable residents to operate autonomously by inducing continuous interest and participation of local residents through the conception stage, planning stage, implementation and self-reliance stage, and allowing them to cooperate together. The business model canvas was reconstructed to be used in the workshop. It was applied to the village of Yesan-gun. As a result of running a resident workshop using the business model Cambus, the lack of resident awareness and illegal garbage dumping were presented as the first problems to be solved. The value of the village was set as 'a village that is clean and clean with a sense of residents, and a good place to live', and users were expressed as 'family' and 'outsiders'. It was suggested that we meet frequently to convey the value of the village by using broadcasting and announcements as a channel to convey the value. Core activities were to cultivate residents' consciousness, such as implementing a campaign against illegal garbage dumping, and to establish and guide separate collection sites. When a garbage collection center is installed, it was estimated that around 2 million won per month for management costs, and it was investigated that it was possible to spend an hour or so twice a month to solve the problem of illegal dumping. If a method to derive village projects based on the derived business model canvas is developed in the future, it will be more practical.

  • Purpose : This study aimed to identify the educational effects of the International Development Cooperation and Healthcare course from 2018 to 2020. Methods : Changes in awareness of international development cooperation (understanding international development cooperation as well as government Official Development Assistance [ODA], thoughts on aid, and thoughts on government's aid scale) were analyzed using web-based surveys. The pre-course survey was conducted 1-2 weeks before the semester started, and the post-course survey was conducted 1-2 weeks after the semester ended. All data were analyzed using the SPSS 26.0 program, and statistical significance was set at p< .05. Results : A total of 314 people participated in the survey before taking the course, and 286 people participated in the survey after taking the course. Analysis of the changes in students' awareness of international development cooperation showed that all items (understanding international development cooperation and government ODA, as well as having thoughts on aid and government's aid scale) were improved. Regarding changes in awareness according to general characteristics, thoughts on aid were statistically significant according to all characteristics except for 2018. Regarding government's aid scale, awareness scores increased after taking the course in students who majored in healthcare, fine arts and athletics, broadcasting and media studies, and digital contents. Conclusion : This study showed that changes in awareness of international development cooperation were largest in second-year students. Compared to changes regarding international development cooperation, government ODA, and thoughts on aid, changes regarding thoughts on government's aid scale were minor. In the future, it is necessary to develop class content suitable for the first-year level and to supplement and operate content that can change the way of thinking on government's aid scale.

  • With the OTT media market growing rapidly, the significance of trustworthy data verification and certification cannot be emphasized enough. This study delves into the crucial need for such measures in South Korea, exploring the steps involved, the technological and policy-related considerations, and the challenges that may arise once these measures are put into place. Drawing on in-depth interviews and the analytical hierarchy process (AHP), this study surveyed various stakeholder groups, both directly and indirectly related to OTT data authentication and certification. By assessing the severity of OTT data-related issues and identifying the requirements for reliability-improvement policies, participants shared their valuable insights and opinions on this pressing matter. The survey results clearly indicate a divided opinion among stakeholders and industry experts on the reliability of OTT data, with some expressing trust while others remain skeptical. However, there was a consensus that advertising-based AVOD is more reliable than SVOD. By analyzing the priorities of authentication and verification, this study paves the way for the establishment and operation of a Korean MRC (KMRC), centered on the OTT media industry. The KMRC will serve as a vital platform for ensuring the authenticity and accuracy of OTT data in South Korea, providing businesses and industry players with a reliable source of information for informed decision-making. This study highlights the pressing need for reliable data authentication and certification in the rapidly growing OTT media market, and provides a persuasive case for the establishment of a KMRC in South Korea to meet this critical need.

  • As technology advanced dramatically in the late 20th century, a new era of science arrived. The emerging era of scientific discovery, variously described as e-Science, cyberscience, and the fourth paradigm, uses technologies required for computation, data curation, analysis, and visualization. The emergence of the fourth research paradigm will have such a huge impact that it will shake the foundations of science, and will also have a huge impact on the role of data-information infrastructure. In the digital age, the roles of data-information professionals are becoming more diverse. As eScience emerges as a sustainable and growing part of research, data-information professionals and centeres are exploring new roles to address the issues that arise from new forms of research. The functions that data-information professionals and centeres can fundamentally provide in the e-Science area are data curation, preservation, access, and metadata. Basically, it involves discovering and using available technical infrastructure and tools, finding relevant data, establishing a data management plan, and developing tools to support research. A further advanced service is archiving and curating relevant data for long-term preservation and integration of datasets and providing curating and data management services as part of a data management plan. Adaptation and change to the new information environment of the 21st century require strong and future-responsive leadership. There is a strong need to effectively respond to future challenges by exploring the role and function of data-information professionals in the future environment. Understanding what types of data-information professionals and skills will be needed in the future is essential to developing the talent that will lead the transformation. The new values and roles of data-information professionals and centers for 21st century researchers in STEAM are discussed.
