The 3D technology has been spread slowly and the reason would be attributed to the fact that most commercialized 3D displays require 3D glasses. There have been various researches on human factors of glass type 3D display. In this study we measured and modeled crosstalk as well as 3D visual fatigue induced by mobile glassless 3D display. Crosstalk as well as visual fatigue varied depending on horizontal position of the 3D mobile display. Measured crosstalk was relative low around the center of the display and it increased at the side of the display. Similar results were found in the measurement of 3D visual fatigue and discomfort. These results imply that human factors should be considered in the process of design and evaluation of mobile 3D displays.

This research analyzes the media which is simultaneously used with TV viewing, the behaviour of multiple media users, and the characteristics of TV programs under Nscreen circumstances. According to the results, TV provides stories and positions it as the main screen (84.5%, n=566), under the Nscreen circumstances. Personal media reproduces stories from TV by utilizing aspects of social media functions such as participation, open communication, community, connectivity, etc. The content is classified under three categories: 1) elicit emotion(point feeling), 2) information production, 3) participation, which is further divided into three subcategories; watch, wish, and result guarantee based on the level of interactivity. This inquiry is based upon diary survey and focus group interviews emphasized the role change of TV, specifically that TV takes a key role in generating original stories with the expansion of screen and social media. Even though users were able to watch the same TV programs at the same time and same place, the different methods of viewing: smartphone, tablet PC, web based mp3 and etc., it reproduced different stories and elicited different characteristics from its TV viewers.

The purpose of this study is to investigate the extensibility of transmedia contents of fantasy genre, and then to examine the characteristics of trans-media contents and analyze how the contents of fantasy genre have become trans-media. The definition and characteristics of the trans-media are distinguished from the existing theories such as One Source Multi Use (OSMU) and Crossmedia. At the same time, this study analyzes the extensibility of the trans-media contents applied to the fantasy genre and it compares with other medias such as novels, videos, games, etc. This shows that the game of the throne was more like to the second order adaptation through video adaptations that succeeded in success compared to the original novels that in expanding into trans-media compared with existing fantasy genre contents represented by the Lord of the Ring. The difference is that although the game of the throne is a fantasy genre content, it does not inherit the existing database genre elements, and it has been found that it has a different aspect from the existing customary form from the role of the character to the whole narrative. The analyzes presented in this study are equally valid for single content, not just for transmedia specific elements.

Since domestic and foreign platform companies and mobile carriers adopt and use different kinds of smart platforms, developers should develop or convert contents according to each smart platform to provide a single smart content for customers. It takes long time and a lot of money to convert the conventional smart contents in order to serve other smart platforms. For the reason, more attention has been paid on Smart Cross Platform or Hybrid Platform, the core technologies of OSMU(One Source Multi Use) in which, once a program is coded, it can be executed in any platforms regardless of development languages. As a result, PhoneGap and HTML5 based Sencha Touch have been introduced. In this paper, we developed the smart virtual machine, which is built in smart cross platform based smart devices, unlike Android, iOS, Windows Phone devices being dependent of platforms, and helps to download and execute applications, being independent of platforms. the smart virtual machine supports C/C++, and Java language, being differentiated from JVM by sun microsystems that supports only Java language and .NET framework by microsoft that supports only C, C++ and C#. Therefore, it provides contents developers with the environment where they can get a wide range of options in choosing a language and develop smart contents.

This paper focuses on proposing an alternative solution via identifying the problems that domestic popular magazines encounter in the context of the recession crisis faced by printed media in accordance with the advent of the digital media era. Firstly, current-state investigation and in-depth interviews with editorial staff of the major 4 domestic women's magazines were conducted to analyze their brand positioning and change of direction in facing the rise of smart devices. Secondly, domestic women's magazines were compared with international popular magazines that have been successfully undergoing digitalization. Accordingly, domestic women's magazines lack the know-how to digitalize their publication and show limitations in collaboration, openness, trans-media, and cross-media. As most women's magazines are unprofessionally composed of gossip articles having popular appeal rather than practicality, it is an urgent issue for them to differentiate their contents from competitors.

Recently, the advance of multimedia hardware has fostered the development of wireless multimedia sensor network which is able to ubiquitously obtain multimedia content such as image or audio from the environment. The multimedia data which has several characteristics such as large size and correlation between the data requires reliability in transmission. However, the existing solution which take the focus on the efficiency of network mainly, is not appropriate to transmit the multimedia data. In the paper, we proposes a reliable asynchronous image transfer protocol, RAIT. RAIT applies double sliding window method in node-to-node image tansfer to prevent the packet loss caused by network congestion. The double sliding window consists of one sliding window for the receiving queue, which is used for prevention of packet loss caused by communication failure between nodes and the other sliding window for the sending queue which prevents the packet loss caused by network congestion. the routing node prevents the packet loss and guarantees the fairness between the nodes by scheduling the packets based on the image non-preemptively. The RAIT implements the double sliding window method by cross layer design between RAIT layer, routing layer, and queue layer. The experiment shows that RAIT guarantees the reliability of image transmission compared with the existing protocol.

A boundary sequence can be a good representation of arbitrary shapes, because it can represent them simply and precisely. However, boundary sequences have not been used as a representation of arbitrary shapes, because the pixel-based shape-features such as area, centroid, orientation, projection and so forth, could not be computed directly from them. In this paper, we show that the shape-features can be easily computed from the boundary sequences by introducing the cross-sections that are defined as vertical (or horizontal) line segments in a shape. A cross-section generation method is proposed, which generates cross-sections of the shape efficiently by tracing the boundary sequence of the shape once. Furthermore, a boundary sequence extraction method is also proposed, which generates a boundary sequence for each shape in a binary image automatically The proposed methods work well even if a shape has holes. Eventually, we show that a boundary sequence can be used effectively for representing arbitrary shapes.

In this paper a new model of storytelling related to patent in the field of business as a sort of Intellectual Property(IP) was proposed. The patent related storytelling is investigated in the view points of variety of customers, purposes and applications which is different from the conventional OSMU, transmedia or crossmedia storytelling. In business there are several stages related to patent such as the initial conceptualization and development of technology, apply for and registration of patent, legal conflict like patent invalidation trial and action for infringement of patent and damages, and the commercialization stage like development of product based on patent, advertisement and marketing. Multiple sources optimized to the purpose in each stage of patent related business as well as to multiple convergence application of a patent. Similarly, multi-use refers to the fact that storytelling can be applied in each stage of patent oriented business. The effectiveness and usefulness of proposed MSMU model is also investigated.

8 bit and 16 bit microprocessors are widely used in the small sited control machine. The embedded microprocessors which is integrated on a single chip with the memory and I/O circuit must have simple hardware circuit and high code density. This paper proposes a 16 bit high code density EISC(Extendable Instruction Set Computer) microprocessor. SE1608 has 8 general purpose registers and 16 bit fixed length instruction set which has the short length offset and small immediate operand. By using an extend register and extend flag, the offset and immediate operand in instruction could be extended. SE1608 is implemented with 12,000 gate FPGA and all of its functions have been tested and verified at 8MHz. And the cross assembler, the cross C/C++compiler and the instruction simulator of the SE1608 have been designed and verified. This paper also proves that the code density$.$ of SE1608 shows 140% and 115% higher code density than 16 bit microprocessor H-8300 and MN10200 respectively, which is much higher than traditional microprocessors. As a consequence, the SE1608 is suitable for the embedded microprocessor since it requires less program memory to any other ones, and simple hardware circuit.
