In these days, space design is evolving to the mixed reality space where fused on-line and off-line. But, standard and measure of mixed reality space has not been suggested and there has been little research about media environment and expression method as a mixed system either. That's why here I suggest four media environments and their characteristics that act not only as a critical point in the mixed reality space based on ubiquitous technology but also as a standard for spatial discerning. 1) Real space that is a media environment only seen by human visual and tactical sense is evolving using expression methods like new materials based on digital technology and LED. 2) Augmented reality space is a media environment using information instruments is expressed with diverse 2D and 3D contents. 3) Cyber Space is a environment depends totally on media instruments is produced by perfect graphic information without any spatial and physical limitations. 4) Augmented cyber space is realized only through the displays in cyber studio and is a space where real objects and graphic information are mixed. Depending on the purpose of the experience, media environment and expressional characteristics of mixed reality space can be fused, blended, and mixed, and that can be realized to the intelligent information space where one can experience without spatial, visual, informational limitations. In the future, studies on physical characteristics of contents according to the media environment characteristics are necessary.

The purpose of this study is to examine the effect of creativity education on creativity of college students through educational medium such as film, animation, documentary, cartoon, advertisement, etc. Therefore, D university in Busan Metropolitan City held a 15-week creativity program for team college students in the second semester of 2016 "creative convergence". In this study, the data collected by the pre - test and post - test using the creativity questionnaire were analyzed by SPSS 18.0 program. The results of this study are as follows. First, the creativity of college students showed a significant difference in problem solving ability scores in the curriculum for media literacy. Second, the creativity of university students showed a significant difference in creative tendency score in media literacy curriculum. The fact that various media such as movies, animations, documentaries, cartoons, advertisements, etc. are educational media that can be easily accessed in everyday life, suggests that the improvement of creativity suggests educational effects to college students and future students.

In this paper. we introduce technologies that service multimedia contents (in brief, we call it UCA (Ubiquitous Contents Access)) to end consumer that have various communication terminal on communication & broadcasting convergence environment and propose system that this technologies are applied. Also, we analyzed relative advantage and playfulness of service technology that is looked in consumer side about proposed service technology. When analyzed relative advantage and playfulness in consumer's view point, proposed communication & broadcasting convergence service model could see that is worth service that consumer can prefer.

In this paper, we present a service model which serves multimedia contents to end consumer(End-user) that have various mobile communication terminals under a communication & broadcasting converged environment that broadcasting and communication networks are linked. A main feature of this service model is that it has a distribution structure that deliver to end consumer via adaptation of content from production of contents offering End to End (E2E) media QoS and personalized contents consumption. The proposed service model may be used as a reference model for distribution of multimedia content in communication & broadcasting converged environment in the future.

안전모 착용 여부를 확인하는 객체 탐지 모델을 물류 현장에서 활용하기 위해서는 안전모를 착용한 경우와 착용하지 않은 경우를 정확하게 탐지해야 한다. 하지만 학습 데이터가 안전모를 착용한 클래스와 착용하지 않은 클래스 간 불균형이 존재하는 경우 해당 데이터만으로는 태스크에 맞게 학습이됐다고 보긴 힘들다. 본 연구는 데이터 증강 기법 적용 시 임의의 데이터에 증강을 적용하는 대신 상대적으로 적은 안전모를 착용하지 않은 클래스를 포함하는 이미지에 대하여 데이터 증강 기법을 적용하였다. 여러 데이터 증강 기법 중 Rotation, Gaussian Noise, 객체를 기준으로 한 Crop을 직접 구현 및 적용하여 객체 탐지 모델인 YOLOv5의 성능을 효과적으로 높이며 더욱 강건한 모델을 개발하는 방법을 제안한다.

Most of the convergence studies argue the reform of the current policy regime of broadcasting and telecommunications in Korea from two perspectives: 1) the media governance perspective and 2) the media industry perspective. The former emphasizes the need of integrity, consistency and efficiency of the regime in the convergence environment, while the latter focuses upon the growth and development of the media industry making the best of economic and industrial opportunities that are spawned by digital convergence. Although their arguments are logical and robust, they are lopsided in terms of legalism and myopic economism due to the linear perception of institutionalism, Bureaucratic administrative practices as well as ostentatious IT policies that have chronically plagued the policy regime in Korea cannot be resolved by simply assimilating distinct regulatory bodies and laws. Unless these two issues are properly addressed, the convergence of media policy institutions would end up a half-success or half-failure contrary to the exportations of existing studies.

This study was designed to analyze trends in the entire convergence research beyond academic research through social media big data analysis at a time when interdisciplinary convergence research is emphasized along with the fourth industrial revolution. For this purpose, about 150,000 cases of texts and titles were acquired for about 10 years from January 2009 to September 2018 in connection with the convergence research in social media, and word cloud and network analysis were conducted. As a results, the research fields that were actively conducted for each period were eco-tech in 2009 and 2010, smart technology in 2011 and 2012, information and communication in 2013 and 2014, robots in 2015 and 2016, and artificial intelligence in 2017 and 2018. Also, the research areas that have been consistently conducted for about 10 years are culture, design, chemistry, nanotechnology, biotechnology, robot, IT, and information and communication. Since this study identifies trends in convergence research over time, it can be helpful to researchers who are planning convergence research direction by understanding the trends of convergence research.

본 논문은 ATSC2.0 기반 8-VSB/MH 융합형 3DTV (A/104 Part 5 Service Compatible 3DTV using Main and Mobile Hybrid Delivery, A/104 part 5) 방식의 서비스 커버리지 및 음영지역을 예측할 수 있는 측정 및 분석시스템 개발에 대하여 기술 한다. ATSC2.0 기반 고정/이동 방송시스템은 8-VSB 로 전송되는 고정 TV 방송서비스(좌영상 전송)와 ATSC-MH 로 전송되는 in-band 모바일 방송서비스(우영상 전송)를 모두 수신하여 좌/우영상의 재생 및 동기화를 통해 융합형 3D 영상을 복원하게 된다. 따라서 융합형 3DTV 수신기는 고정 및 모바일 방송신호를 모두 수신하여야 융합형 3D 영상복원을 할 수 있으며, 방송사 입장에서 서비스 커버리지 측정을 하기위해서는 8-VSB 및 ATSC-MH 신호의 수신여부를 모두 측정하여야 한다. 본 논문에서는 이와 같은 RF 수신전계강도 파라미터 및 GPS 정보등을 실시간으로 모니터링하여, 시스템 사용자에가 융합형 3DTV 서비스 커버리지 측정 및 분석을 통해 서비스를 위한 RF 방송망 셀 구성 및 음영지역을 예측할 수 있는 ATSC2.0 융합형 3DTV 서비스 커버리지 분석기 구현에 대한 내용을 기술한다.
