The media has depicted an abrupt socio-technological change in the Republic of Korea with the 4th Industrial Revolution. Because technologies cannot realize their potential without social acceptance, studying conflicts incurred by such a change is imperative. However, little literature has focused on conflicts caused by technologies. Therefore, the current study investigated media coverage regarding conflicts related to the 4th Industrial Revolution from 2016 to 2020 in the Republic of Korea, applying text-mining techniques. We found that the overall amount and coverage pattern conforms to the issue attention cycle. Also, the three major topics ("SMEs & Startups," "Mobility Conflict," and "Human & Technology") indicate quarrels between conflicting social entities. Moreover, the temporal change in media coverage implies the political use of the term rather than technological. However, we also found the media's deliberative discussion on the socio-technological impact. This study is significant because we expanded the discussion on media coverage of technologies to the realm of social conflicts. Furthermore, we explored the news articles of the recent five years with a text-mining approach that enhanced the objectivity of the research.

Hashtags (#) have received a great deal of attention from academia and industry as an effective digital tool for engaging social media users and facilitating electronic word-of-mouth for brands. We delved into motivations concerning people's brand-related hashtag-posting behavior on social media. The findings revealed three motivations for posting brand-related hashtags on social media: social acceptance, brand altruism, and incentive seeking. Additionally, we examined the relationships between motivations and brand relationship variables. The results showed that social acceptance and brand-related altruism predicted all of the five relationship variables (i.e., brand attitude, brand trust, brand affective and calculative commitment and brand loyalty), while incentive-seeking predicted brand calculative commitment and brand loyalty. The findings of the study provide some meaningful insights into the development of brand communication strategies and help marketers capitalize on social media platforms to achieve higher user involvement.

At present multimedia service composed of voice, data, and video service is prevalent in the Internet. As such, wide-scale penetration of Internet service imposes tremendous pressure to the network infrastructure such as the media servers and links as well as the nodes. In addition, users from a large-scale population require broad bandwidth and high level of QoS. This requires a network with reliable and scalable services to customers, which also necessitates a realistic method for the design of the a media server. In this work, we explore the influence of user's behavior about delay on the performance of media server that takes into account the system and user attributes in a realistic manner. By incorporating user's behavior about the delay-sensitivity, we present an analytic framework for the evaluation of the performance of the media server, via which we illustrate a meaningful intuition in the provision of Internet multimedia service.

In this paper, we present new methods for rapid high-resolution range sensing using green-blue stripe pattern. We use green and blue for designing high-frequency stripe projection pattern. For accurate and reliable range recovery, we identify the stripe patterns by our color-stripe segmentation and unwrapping method. The experimental result for a naked human face shows the effectiveness of our method.

In this paper, we propose a user-centric conflict management method for media services which exploits personal companions for the harmonious detection and resolution of service conflicts. To detect conflicts based on the varying characteristics of individual users, the proposed method exploits the unified context describing all users attempting to access media services. It recommends and mediates users' preferred media contents through a shared screen and personal companions to resolve the detected conflicts. During the recommendation, a list of preferred media contents is displayed on the shared screen, and a personally preferred content list is shown on the user's personal companion comprising the selection of media contents. Mediation assists the selection of a consensual service by gathering the users' selections and highlighting the common media contents. In experiments carried out in a ubiHome, we observed that recommendations and mediation are useful in harmoniously resolving conflicts by encouraging user participation in conflict situations.

본 연구는 마을공동체미디어의 관계와 소통 구조를 이해하기 위하여 네트워크 분석방법을 통해 커뮤니티 미디어 참여자 네트워크의 관계망 특성을 분석하였다. 연구대상으로 서울시 마포구의 마포FM을 선정하였으며 네트워크 분석 방법에 기초하여 마포 FM의 생산자를 중심으로 형성되어 있는 참여자들의 네트워크의 밀도와 네트워크 중심성을 분석하였다. 또한 분석 결과의 해석과 이해를 위하여 추가적으로 참여자에 대한 심층 인터뷰 실시하였다. 분석 결과, 마포FM은 지역 활동가를 중심으로 하는 마을공동체 조직가의 역할을 수행하고 있으나 일반 주민들의 참여의 정도와 소통 방식은 이론적 논의와는 달리 낮은 밀도와 소수에 집중되어 있는 낮은 수준의 관계성을 보여주고 있었다. 이러한 결과의 원인과 배경을 이해하기 위하여 참여자 네트워크에 포함된 활동가들의 심층 인터뷰 자료를 분석하고 이를 바탕으로 국내 커뮤니티미디어가 공동체와 그 구성원을 위한 콘텐츠의 생산과 공유를 어떻게 진작 시킬 것인지를 논의하였다.

The purpose of this study had started from trying to look for a new standard in new media era and sounding out possibility of perspective of digital poetry, and had been extracting interpretational elements based on characteristics of otology in digital poetics research in technical method. Through examination of many documentary records, we suggested interpretive elements of medial space based on meaning and the theory of digital poetics. We deduced three perspectives based on relationship between the basic thesis in poetics and interpretive elements of medial space. We used them as tool for analysis of example. We chose as an example that change of program in space is clear through connection of media and space in where new form of creation happens through digital instruments and chose article as subject to which digital technology is applied and had been since 2000, The result of this study is as following: First, epistemological analysis about a space of digital media in new media era requires poetical approach unlike aesthetic approach. We can endow creative action and creation process with significance and pay attention to technical method of manufacturing, stating appropriateness of perspective in digital poetics. Second, the justice of digital poetics and its basic thesis help derive analytic elements from medial space and study purpose of production, technical method, ontological characteristics, which are three perspectives of digital poetics. Third, it analyzed characteristics of example according to three perspectives above and we can analyze characteristics of spacial expression in space of digital media into potential, trans-active, and semiosis space. It would be possible through analyzing examples in digital poetic perspective to overlook new methods of design in 21th and various perspectives and possibilities of medial space design.

Perpendicular patterned magnetic media have been regarded as a prime candidate to achieve an ultra-high magnetic recording density of over 1 Tera-bits/$inch^2$. Patterned magnetic media with nanoscale patterns have been fabricated using various nanopatterning technologies. We focused on the two technical issues of nanoinjection molding technology. Firstly, we have investigated a cost-effective method to fabricate metallic stamps. Secondly, we focused on the analysis of nanoinjection molding with passive heating, where the replication of 50 nm nanopillar arrays was successful. The effect of the thermal insulation layer on the replication quality was examined by analytical and experimental methods. Finally, we deposited a magnetic layer on a injection molded nanopillars and measured. Our methodology can provide cost-effective mass-production for patterned magnetic media.

In this paper, we propose a DRM(Digital Rights Management) system for streaming media which can not only protect streamed MPEG-4 content but be easily integrated with existing MPEG-4 streaming system. To protect MPEG-4 media more effectively and more securely, encryption should be considered on encoding phase and also streaming server should be designed to support DRM. However that means it cannot support existing streaming system. Our approach is to design a DRM system independent to the streaming server. So, we used an encryption method which can be applied to compressed MPEG-4. The processing time of decryption in client system must be minimized to guarantee the QoS of streaming service. To satisfy this requirement, it is essential to analyze the effect of DRM on performance. We made some performance test and present the result. Also, we apply proposed system to ISMA(The Inter net Streaming Media Alliance) streaming system which is open standard for MPEG-4 media streaming.

We present a real-time interactive particle-art with human motion based on computer vision techniques. We used computer vision techniques to reduce the number of equipments that required for media art appreciations. We analyze pros and cons of various computer vision methods that can adapted to interactive digital media art. In our system, background subtraction is applied to search an audience. The audience image is changed into particles with grid cells. Optical flow is used to detect the motion of the audience and create particle effects. Also we define a virtual button for interaction. This paper introduces a series of computer vision modules to build the interactive digital media art contents which can be easily configurated with a camera sensor.
