The Petroglyph is a drawing on the rock which reflects the art, religion, myth, and life style of prehistoric society. Recently lots of researches have been studied to develop the contents applying the petroglyphs in the fields of exhibition, education, entertainment, and commercial. This research aims to find some possible VR contents based on the petroglyphs text. The review on the Ulsan petroglyph museum which is the first and the only petroglyph museum in Korea was the first step. Some limitation and problems were found in the current contents which could be overcome by using VR technology. The next step was the overall review of VR system and devices, and then I analyzed five cases of VR contents which specifically applied to the cultural heritages. Based on the analysis of case studies I propose some possible VR contents more immersive and interactive covered with whole range of petroglyphs context, environmental, social, cultural, technical and artistic.

As the distribution rate of the Smart mobile increased, the software technology and ideas for the ubiquitous systems advanced day after day to establish an environment where the public can easily access and experience such technologies. The communication between an individual and the many became more convenient through the social network services (SNS) and the individuals started to attempt to communicate in various methods. The communication methods and techniques became more diverse and the media art pieces focusing on the communications among many also became more interesting. This study attempted to create a prototype of the visual communication media art through the indirect participation of one of the widespread SNS, Twitter, for the communication and also to suggest the direct and indirect communication routes among the humans. In addition, the use of the typography in the pieces also attempted to examine a new type of work that combines the SNS and media art while delivering the text messages.

The activity to share personal daily life through social media is becoming more common. In this case, photographs as well as text are used a lot; it has been as easy as winking to clip others' photographs just as it's very easy to take and post pictures. If the picture is the photographic work protected by the copyright law, however, the clipping should be paid close attention. If you use others' photographic works without authorization, you infringe their copyright; if you post them on your social media such as blog, you infringe the right of reproduction, interactive transmission and exhibition. Even though the clipping is permitted, if you'd like to use the photographic works for a profit-making purpose, you should get additional authorization. Others' photographic works are occasionally altered and used for the purpose of avoiding the argument in relation to the infringement of copyright; this act means that it's the infringement of the right of reproduction, the right to preserve the integrity and the right of the production of derivative works for degrees of alteration. We can download others' photographic works with a few mouse clicks thanks to the technology of capturing the screen; we have to recognize that all the acts technically possible are not always legal.

인터넷의 성장과 더불어 수많은 응용시스템들이 인터넷 기반 시스템으로 바뀌고 있다. 특히, 인터넷 기반 전문가시스템은 다양한 구조와 방법으로 설계될 수 있고 이미 제작되었던 수많은 인터넷 기반 전문가시스템들은 그 나름대로의 장단점을 가지고 있다. 본 연구는 특정 전문가시스템의 개발이 아니라 WWW(World Wide Web)을 사용자 인터페이스로 이용할 수 있는 전문가시스템 쉘에 관한 연구이다. 본 시스템은 WWW 하부구조에 대한 의존성을 제거, 클라이언트와 네크워크에 부담 격감, HTML과 부합하는 텍스트에 기초한 통신과 같은 장점 외에 중앙 집중적 다중 사용자 접근 관리 기능을 제공한다. 본 시스템은 다중사용자를 위한 서버/클라이언트 환경 구축을 위해 소켓을 이용하여 큐잉(queueing)과 직렬화(serialization)를 해결하고 비연결 지향적인 WWW의 특성으로 인한 사용자 관리의 어려움은 사용자의 IP 주소와 Timer를 이용한 휴무기간 검사를 이용하여 해결한다.Abstract The growth of internet drives many applications into internet-based systems. Internet-based expert systems can be designed with various concepts and methodologies, and they have their own merits and demerits. This papers is a study on a development of not expert system itself but expert system shell which is able to use WWW(World Wide Web) as user interface. The suggested system supports functions on multiuser management controlled by a server system as well as independence on development environments, minimization of the load for clients and network, and text-based communications such as HTML. The system uses socket, which solves problems of queuing and serialization, in order to construct multiuser server/client environmen and also the system solves the non-connective property of WWW which makes it difficult to control users and processes by using IP address and idle time which is supported by the timer.

The purpose of this study is to investigate the meaning of cultural practices of videogame audience with 'mod'. Videogame audience members are recognized as very active and interactive beings compared with other interpretive media audience members. Especially mod is one of the most dramatic cultural situation of videogame. It's very prominent properties are 'activity' and 'interactivity'. Videogame audience members, so called 'gamers' modify videogame software as their own sake and use it as their own intention. Modifying and playing with videogame, or 'modding' is very strong cultural program of gamer. Mod is one of avant-garde technology but its practice is not always radical. I observed practices of the members of Naver cafe 'Elderscroll' playing . They used mods of for their phallocentric desire. And they construct a hierarchical and top-dowon membership. So advanced technology and cultural media and text from it does not assure the same advanced contents.

The way people read news is changing, from print to screen. In this study, we aimed to understand the impact of the use of infographics in news on readers. According to a study conducted by Reuters Research Institute at the University of Oxford in 2017, the proportion of online consumers of news is steadily increasing, with over 51 per cent of Americans receiving news via social media. Additionally, newspaper subscription rates are rapidly declining. According to previous studies, the understanding of text information is higher in print media than on screen. Therefore, to compensate for the weaknesses in the understanding of online news, online news media are providing infographic news services to deliver good news. Therefore, this study attempted to understand the impact of using infographics in the news. To this end, three experiments were conducted. The findings from the study indicate that the use of infographics in news has a positive effect on users in terms of the variables measured, including cognitive effect and acceptance of news. As compared with print news, on-screen news was not as effective in terms of comprehension. However, we propose interactive infographics to enhance communication effect along with improved design.

A process control graphic system is proposed as an efficient tool for monitoring the operation of power plant. It uses the multi-processor structure with 60 Kbyte shared memory as an implemental type of the distributed computer system, so that it is flexible, functionally extensible, and applicable to real-time process. The shared memory is used as a real-time database handling the process values and operator's commands. The database files, generated by the user-interactive graphic editor developed for the system or text editor, have the characteristics of simplicity and user-friendliness. The process control graphic system, that can monitor the operation of boiler and function as a backup controller in case of failure in boiler controller, is applied to Ulsan power plant. As a result, it displays the operating data of the boiler process without error by 14 pages of color graphic image according to the operation menu, and additionally functions well as a fault-tolerant control system.
