The globalization of the world, fueled by the Internet, made possible for individuals to access the cultures around the world, other than their own, easier than ever before. But among those rapidly sought out sub-cultures, the video gaming industry, once a niche market mostly for nerds and geeks, now has become one of the biggest entertainment businesses in the world. In a video game, one of the critical elements that could determine its success or failure is the characters featured in the game. And as the countless number of animated characters from many different video games from the past few years have become incredibly popular among the audiences around the world, the expectations from the fans also grow higher every time a new game comes out. Ultimately this has forced the video game developers to come up with more unique and interesting characters for their video games. And at this point, where a video game character is more than just fictional fantasy but a brand to be recognized, it is worth paying proper attention to the video game characters that represent Korea. Hence in this study, we will take a look at Han Ju-Ri, a Korean character featured in Super Street Fighter IV, a competitive fighting game developed by Capcom, one of the world's most recognized video game companies that started its life as an arcade video game, developer but eventually ventured its business into the online world. The study will propose a complete overhaul of the character by incorporating Korea's own traditional looks.

Software RAID(Redundant Arrays of Inexpensive Disks) is defined as a storage system that provides capabilities of hardware RAID, and guarantees high reliability as well as high performance. In this paper, we propose an enhanced disk scheduling algorithm and a scheme to guarantee reliability of data. We also design and implement software RAID by utilizing these mechanism to develop a storage system for multimedia applications. Because the proposed algorithm improves a defect of traditional GSS algorithm that disk I/O requests arc served in a fixed order, it minimizes buffer consumption and reduces the number of deadline miss through service group exchange. Software RAID also alleviates data copy overhead during disk services by sharing kernel memory. Even though the implemented software RAID uses the parity approach to guarantee reliability of data, it adopts different data allocation scheme. Therefore, we reduce disk accesses in logical XOR operations to compute the new parity data on all write operations. In the performance evaluation experiments, we found that if we apply the proposed schemes to implement the Software RAID, it can be used as a storage system for small-sized video-on-demand servers.

With the recent advances in radiological science, there was radiographic techniques development and several researches to diagnosing dysphagia. We proposed the new Imaging technology based on Near Infrared radiation (NIR) for video fluoroscopic swallowing study (VFSS). To reduce the risk of the VFSS examination for swallowing rehabilitation, multi-NIR camera system comprised. Based on the multi-NIR camera imaging system, Computational simulation was conducted to identify the potential of the multi-NIR camera imaging system as a clinical tool (screening system). As a result of the simulation applied in this study, the proposed system has a potential to be a clinical solution although there is a few of limitations. we believe that it will be a good tool to support the VFSS as a screening technology in clinical fields.

This study was conducted to develop a Web-GIS based monitoring module of smart city that can effectively respond, manage and improve situation in all stages of illegal dumping management on a city scale. First, five technologies were set for the core technical elements of the module configuration. Five core technical elements are as follows; video screening technology based on motion vector analysis, human behavior detection based on intelligent video analytics technology, mobile app for receiving civil complaints about illegal dumping, illegal dumping risk model and street cleanliness map, Web-GIS based situation monitoring technology. The development contents and results for each set of core technical elements were evaluated. Finally, a Web-GIS based 'illegal dumping monitoring module' was proposed. It is possible to collect and analyze city data at the local government level through operating the proposed module. Based on this, it is able to effectively detect illegal dumpers at relatively low cost and identify the tendency of illegal dumping by systematically managing habitual occurrence areas. In the future, it is expected to be developed in the form of an add-on module of the smart city integration platform operated by local governments to ensure interoperability and scalability.

This paper presents the latest Ethernet standardization of in-vehicle network and the future trends of automotive Ethernet technology. The proposed system provides design and optimization algorithms for automotive networking technology related to AVB (Audio Video Bridge) technology. We present a design of in-vehicle network system as well as the optimization of AVB for automotive. A proposal of Reduced Latency of Machine to Machine (RLMM) plays an outstanding role in reducing the latency among devices. RLMM's approach to real-world experimental cases indicates a reduction in latency of around 41.2%. The setup optimized for the automotive network environment is expected to significantly reduce the time in the development and design process. The results obtained in the study of image transmission latency are trustworthy because average values were collected over a long period of time. It is necessary to analyze a latency between multimedia devices within limited time which will be of considerable benefit to the industry. Furthermore, the proposed reliable camera and video streaming through optimized AVB device settings would provide a high level of support in the real-time comprehension and analysis of images with AI (Artificial Intelligence) algorithms in autonomous driving.

The prevalence of We-Media short videos has attracted emerging independent fashion designers (EIFD), a new force in the fashion industry directing their brand promotion to We-Media for amassing online followers. However, compared to famous content generators, EIFDs' creative, design-based visual appeal has not provided them with the significant edge. The former's success is admittedly supported by the platform backstage algorithm. Yet, the content is the cornerstone for building relationship between the sender and the reception. The authentic perception of the content is one of the basic appeals for which the audience chooses to follow the source. Therefore, with the EIFD short video as the research content, this study is established from the audience's perspective to understand the different dimensions of their authentic perceptions of EIFDs short video. The study was conducted mainly in the form of the Q method. The collection of 52 Q samples were realized through the Focus Group Interview and literature review on multidimensional authenticity. Thirty-six subjects participated in the sorting of the Q-sets. Finally, four dimensions of audience authenticity perceptions of EIFDs were derived: 'ingenuity', 'relevant', 'transparent', and 'experiential'. The corresponding short video content design strategies are suggested for effective communication of EIFDs and their personal brands.
