Recently, webtoons-based animations have been expanding in Korea, where the role of mobile devices is growing, and media videos such as "YouTube" and "Tik-Tok," which have shorter screening and production cycles than traditional feature films, dramas, and animations, are attracting attention and being enjoyed by public. In order to produce animation content that fits the trend of this shortening video and production cycle, efficiency must be increased not only in story but also in production. Production methods and production technologies need changes to increase efficiency. Animation using motion capture, which is highly production-efficient, is widely used in movies that shows realistic movements, but still has little use in producing cartoon-style animations with exaggerated movements. We analyzed the production method of 2D animation and CG animation and applied the result to CG animation to increase the efficiency of production and production. The methods of production through such experiments are expected to help improve the efficiency of producing animation content that is suitable for the latest trends such as webtoon animation.

This study explores the formational process of KBS PD's professional identity in the 1970's, focusing on everyday work and workplace for program production. In terms of salary and social-cultural status, a television PD was not a desirable occupation in the 70's. Since the beginning of radio broadcasting, production of culture and education programs had been sub-categorized under Programming Division. Also, it has been claimed in several researches that in the 70's, the production of education and cultural programs had visibly grown owing to the political necessity of policy PR and campaigns, and the introduction of new broadcasting equipment and technologies for producing the mentioned political campaign programs. However, this study argues that the main force that led to such developments was the cultural practices and the production spirits of the KBS PD's. These PD's trained themselves in production workplace from the bottom by assisting film directors and learning from cameramen about the film making and post-production process. Moreover, in the transitional phase from film to magnetic tape recorder, they established themselves as main subjectivities of production by developing Division of Culture and Education as a specialized and independent sector. The "program production spirit and DNA" that evolved from the experiences of working in poor production environment served as a force for developing professional and self identity. However, the culture and education PD's of the 70's were still tied down to the limited roles of simply providing technological and productional 'professionalism' within the hegemonic structure of the strong state. As with the members of any other social domain at the time, PD's had restricted roles to play and putting in effort and competing to create better programs was the only 'freedom' that was allowed. This study argues that under such condition, KBS PD's implemented two strategies to construct their own professional identities: one was to distinguish themselves from official broadcasters, and the other was to distinguish themselves from commercial broadcasters. Unfortunately, ethical practice as a professional became nothing more than an issue of personal morality and broadcasting's public responsibility was lost under the shadows of commercial broadcasting.

This document describes the technologies related to internet protocol (IP)-based media production systems. As high-capacity, high-quality data transmission increases, broadcast production platforms are shifting to IP. The IP-based production system uses the network by sharing resources and is easy to control centrally. It also facilitates software-based cloud production. A cloud IP-based media production platform can work regardless of dedicated hardware and can easily collaborate. Associations and industrial groups have created common standards related to production, and manufacturers are developing solutions with their technologies based on their product competitiveness. This study investigates the open standard technologies used for IP-based media production and technology trends in the ProAV industry and describes the production in the cloud environment and cloud AI-based production technology trends.

Due to the recent advances in high-speed communication technologies as well as the easy production of high-quality video contents, IPTV is becoming increasingly popular. Meanwhile, as the number of IPTV channels increases, channel search time to find the desired channel keeps increasing. In this paper, we discuss how to improve the channel search latency in IPTV, and introduce caching and prefetching techniques that are widely used in memory management systems. Specifically, we adopt memory replacement, prefetching, and caching techniques in IPTV channel search interfaces and show the effectiveness of these techniques as the number of channels are varied.

Red rose petals are usually disposed but they are an abundant source of phenolics and traditionally used as food supplement and as herbal medicine. Of the Various phenolics, they are known to have anticancer, antioxidant, and anti-inflammatory properties. In this study, we investigated the anti-inflammatory effects of red rose ethanolic extracts (GRP) on lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results demonstrated that pretreatment of GRP (500㎍/mL) significantly reduced NO production by suppressing iNOS protein expression in LPS-stimulated cells. Anti-inflammatory effects by red rose petals were observed in the following. Red rose petals inhibited the translocation of NF-κB from the cytosol to the nucleus via the suppression of IκB-α phosphorylation and also inhibited LPS-stimulated NF-κB transcriptional activity. These findings suggest that red rose petals exert anti-inflammatory actions and help to elucidate the mechanisms underlying the potential therapeutic values of red rose petals. Therefore, red rose petals could be regarded as a potential source of natural anti-inflammatory agents.

This research entailed the production of stereoscopic 3D (S3D) contents using 2D-to-S3D conversion for exhibition at a museum and subjective evaluation. Hybrid production combining S3D images of existing live-action videos using the 2D-to-S3D conversion technology and computer graphic ones created via stereo rendering was conducted. Design and control of the chronological analysis of the parallactic angle was conducted on the produced contents, using binocular information as well as subjective evaluations, with the intent of conducting an investigation on the characteristics of such contents from the perspectives of the producers and viewers. An investigation was also conducted on the effects of the viewing position on the impressions of the S3D images.

해마다 실시되고 있는 대학수학능력시험의 듣기 평가시험에 있어서, 고사장 및 지점별 음향 성능에 기인한 레벨 편차와 명료도를 산출하여 학생 선발의 공공성과 객관성을 검토해 보고자 한다. 일반적으로 듣기 평가가 이루어지는 각 고사장은 듣기 평가 실시에 지장이 없는 고등학교 교실로 지정하고 있지만, 균등한 음 환경을 제공해야 하는 시험의 성격에 반해 학교 자체의 방송 시설을 그대로 사용하는 것은 평가의 형평성 및 객관성에 충실하지 못하게 되는 요인이 된다. 따라서, 각 고사장의 확성 시스템에 따른 음성 전달품질과 수험생간의 좌석별 음압 레벨 및 명료도를 평가하였고, 실험 결과 RASTI를 비롯한 음성 및 음절 명료도를 나타내는 파라메터에서 좌석별로 큰 편차가 있는 것으로 분석되었다.

In the last few years, a new type of synchronous social networking services (SNSs) has emerged—social live streaming services (SLSSs). Studying SLSSs is a new and exciting research field in information science. What information behaviors do users of live streaming platforms exhibit? In our empirical study we analyzed information production behavior (i.e., broadcasting) as well as information reception behavior (watching streams and commenting on them). We conducted two quantitative investigations, namely an online survey with YouNow users (N = 123) and observations of live streams on YouNow (N = 434). YouNow is a service with video streams mostly made by adolescents for adolescents. YouNow users like to watch streams, to chat while watching, and to reward performers by using emoticons. While broadcasting, there is no anonymity (as in nearly all other WWW services). Synchronous SNSs remind us of the film The Truman Show, as anyone has the chance to consciously broadcast his or her own life real-time.

In recent years, Unreal Engine has been increasingly included in the animation process produced in the studio. In this case, there will be more than one of main software, and it is very important to accurately transfer data between the software and Unreal Engine. In animation data, not only the animation data of the character but also the animation data of objects interacting with the character must be individually produced and transferred. Most of the objects that interact with the character have a condition of constraints with the part of character. In this paper, I tried to stipulate the production process for extracting animation data of constrained objects, and to analyze why users experience difficulties due to the complexity of the regulations in the process of executing them. And based on the flowchart prescribed for user convenience, I created a program using a Python script to prove the user's convenience. Finally, by comparing the results generated according to the manual flowchart with the results generated through the script command, it was found that the data were consistent.

In producing anamorphic 3D advertisement projects, it is necessary to apply the principles of illusion art to distort the images output to the screen (Image Distortion) so that their display aligns with our visual perception in a real three-dimensional environment. We focuse on the methods of image distortion in the creation of content for anamorphic 3D advertisement screens in this thesis. We propose using Unity 3D's real-time rendering instead of the offline rendering method of compositing method, and employing UV grid mapping to replace the manual correction in Adobe After Effects(AE). The significance of this paper lies in simplifying the image distortion processing workflow in anamorphic 3D projects and optimizing the image distortion creation methods used in compositing method. In outdoor anamorphic 3D advertisement projects, the proposed image distortion creation method demonstrates significant advantages in terms of production time, process simplification, flexibility, and expansion possibilities. Our research provides new perspectives and methods for the creation of anamorphic 3D content, offering theoretical and methodological references for professionals working on similar contents.
