The purpose of study is not only analyzes the space images expressed with mass-produced furniture of the time and economy throughout the cover pages of IKEA published catalogs since 1951 to 2015 but also is set to deduct the characteristics of spatial expression regarding the usage of digital media applied catalogs which is to be published along with the 2015 catalog. Thus, throughout research of basic literature such as domestic and foreign academic material, books, and websites, the theoretical consideration of the meaning of IKEA's pursuit of selling manufactured furnitures is foregone. Based on the above, Analyze and organize periodically applied interior space in accordance with context characteristic by understanding the attribute of catalogue from expansion of media space applied new digital media. The importance of research on IKEA is not only the quality of products designed by them, but emotional aspect that deeply penetrate customer's actual daily life. Implication of digital media message to advertisement is a important role in society that shares digitalized information. IKEA's innovative attempt of connection to new world using traditional method of marketing expression and smart device may help people better understand space.

This paper analyzed technologies related to video and sound device manufacturing closely related to media images, divided applicants into companies, research institutes, universities, individuals and the public, and conducted technical statistical analysis, collective intelligence analysis, and open innovation analysis. It is necessary to express innovative ideas through technology in research institutes or universities, and efforts are needed to expand technologies in the media field in universities. Looking at the contents of patents actually filed, patents filed by companies or individuals were mostly related to media technology, and patents filed by universities and research institutes were mostly related to media content. This means that hardware technology patents should be developed extensively and in-depth in an inseparable relationship between media technology and content, and should be a driving force for software content to play a more diverse and creative role.

In this paper, we propose a protocol structure of a portable 4K Ultra High Definition (UHD) broadcast relay device that utilizes a 5G mobile communication network as a transport channel, and construct a prototype to conduct a broadcast relay performance test through a 5G mobile communication network. The test shows that the encoding time of the 4K UHD encoder is from a minimum of 86.28ms to a maximum of 88.41ms, the relay delay time in the 5G mobile communication network is 13.645ms on average, the delay variation is 17.49ms, and the glass-to-glass delay time is 289.90 on average, the delay variation is 27.63ms. Using the developed prototype, a relay test between Seoul and Anseong is conducted, and the possibility of 4K UHD broadcasting through a 5G mobile communication network is confirmed.

Today the influence of digital video media grows bigger due to the development of information and telecommunication gradually and most of juveniles spend a number of image contents with their smart phones and computers. And they not only consume such image contents but also upload the videos they make at YouTube or Vimeo by recording and editing them by themselves. As we learned from such phenomenon, the education of media that uses and expresses the video in various environment such as making, reading and expressing video media is very important. The education of using the advance digital device and software of producing image contents is essential as current education of media cannot be discussed without that. This study treats the education of media based on the view point of education on image contents production. It discusses the education method that we can learn from the process of image contents production based on Non-Linear Editing System.

This paper proposes a user interface, on see-through system environment which shows the images via two different cameras, that also ordinary user can control the computer systems or other various processes easily. For that, we include an AR technology to synthesize the virtual button to the image which is captured by the camera real-time. And we were looking for the hand position in the image to judge whether the figure selects the button. And the result of judgment visualizes through changing of the button color. The user can easily interact with the system by selecting the virtual button in the screen with watching the screen and moving her fingers at the air.

General lighting will be replaced into LED due to the high efficiency, low power consumption, long life than conventional light, moreover, since it is a basically semiconductor device that can convert the electric energy to visible light at a very high speed, using these characteristics can be performed communication modulation via the high-speed ON-OFF switching. Recently, visible light communication (VLC: Visible Light Communication) technology is received attention and there have been many researches. This paper is implemented media signal transmission by combining LED with VLC, a transmitter used the LED light-emitting device and receiver used an infrared sensor. In order to increase the efficiency of the communication system to improve the existing LED visible light communication driver of power conversion efficiency and thermal issues that is applied to the visible light communication in order to improve the speed of transmission media to research a new way of LED driver.

A selective catalyst reduction system (SCR) with an integrated bypass unit is proposed. Through simulations of the SCR, variations in flow to the catalyst due to the particular shape of the bypass shutting device in the SCR are also studied. The commercial software Ansys Fluent is used to develop the simulations. For the simulations, the catalyst of the SCR is modeled using the porous media method to reduce the calculation time and number of meshes, which is necessary because of the detailed modeling of the catalyst. Simulations are performed based on changes to the entrance angle to the catalyst and the size of the bypass shutting device. Finally, simulation results are used to compare and analyze the average velocity and uniformity of the flow to the catalyst.

In this paper, the channel decoder promising reliable data retrieving in noisy holographic channel has been developed for holographic WORM(write once read many) system. It covers various DSP(digital signal processing) blocks, such as align mark detector, adaptive channel equalizer, modulation decoder and ECC(error correction code) decoder. The specific schemes of DSP are designed to reduce the effect of noises in holographic WORM(H-WORM) system, particularly in prototype of DAEWOO electronics(DEPROTO). For real time data retrieving, the channel decoder is redesigned for FPGA(field programmable gate array) based hardware, where DSP blocks calculate in parallel sense with memory buffers between blocks and controllers for driving peripherals of FPGA. As an input source of the experiments, MPEG2 TS(transport stream) data was used and recorded to DEPROTO system. During retrieving, the CCD(charge coupled device), capturing device of DEPROTO, detects retrieved images and transmits signals of them to the FPGA of hardware channel decoder. Finally, the output data stream of the channel decoder was transferred to the MPEG decoding board for monitoring video signals. The experimental results showed the error corrected BER(bit error rate) of less than $10^{-9}$, from the raw BER of DEPROTO, about $10^{-3}$. With the developed hardware channel decoder, the real-time video demonstration was possible during the experiments. The operating clock of the FPGA was 60 MHz, of which speed was capable of decoding up to 120 mega channel bits per sec.

As the broadcast, tele communication and media technology develop, the media are divided into various specialities from the internet to the mobile device. An advertising creative in the field, an innovative changes are taking place that had not been in the era of the passed traditional media TV, newspaper, magazine and etc. It's not but the various media's dividing, also the consumers who use the media are evolving in their media behavior from a passive attitude to a positive one. In other words, They consumers receive the advertising messages with positive attitude to researching the message in the searching tool by themselves and participate, act, and diffuse their acknowledgements. In this thesis, as the advertising creative circumstance like this, these varied advertising creative are tried to explained by the three dimension module that is suggested in this thesis.
