Crowdfunding, a way of raising small size investments or donations from numerous individuals, mostly through internet to fund a project, has attracted global interests. The growth of the social network platform has made crowdfunding easier especially for those in the arts and culture sector. Despite the growth of such vehicle, there has been not much empirical research on the subject. We investigated the relationships between the information in the web sites and its contribution to the success in fundraising. We have sampled 161 projects that were uploaded on Tumblbug.com and studied the type of information that lead to a successful fund raise. As a result, we fould that the contents characteristics including motion-pictures, images, and lengthy texts have positive impacts on the success of fundraising. Fundraising rewards did not show any impacts.

This paper proposes an effective keyword extraction method for the Web videos. The proposed method classifies the Web video pages in one of 4 types. As such, we analyzed the structure of the Web pages based on the number of videos and the layout of the Web pages. And then we applied the keyword extraction algorithm fit to each page type. The experiment with 1,087 Web pages that have total 2,462 videos showed that the recall of the proposed extraction method is 18% higher than ImagerRover[2]. So, the proposed method could be used to build a powerful video search system for WWW.

The video production, as a recording data about the archeological survey, has advantages to be visualized in actuality and historical fact presented objects with elements such as moving images, audio(voice) and text(subtitle). While the report with text and images such as photographs and drawings does not present exactly, the video production can record a concrete excavation process to be difficult of represent with former media. To make a practical use the video production in archeological surveys, the use dimension should be expanded to the entire archeological excavations and the shooting and editing work should be done by those video production-specialized staffs. Ultimately, when this video production device is used but also for the survey purposes but also for the education, exhibition, and even commercial purposes, it can have the substantial meaning as a survey tool.

When reviewing animation based on a mythical motive, the mythical imaginary power has been dependent only on audio visual senses thereby resorting to a fantasy nature regardless of reality, or there has been too much emphasis on an educational message and animation has been utilized as a conflicting composition between good and evil. Therefore, this thesis reviewed 1) whether the author's consciousness was reflected in animation according to the contemporary interpretation of mythical imaginary power and 2) whether the author included an internal meaning of a universal subject by having a short animation that was produced by actively utilizing a mythical motive as a text. Also, based on the analysis, the study deduced the conclusion that the most important thing in animation based on a mythical motive is the author's consciousness that reinterprets the theme of 'universality' from a contemporary perspective before expressing the mythical objects through the senses such as by a brilliant image and sound. The products of such an analysis are supposed to solve the problem over how mythical factors need to be applied and utilized in creating animation.

User Generated contents(UGC) interchange with internet users actively in Web2.0 environment. According to growth of content sharing site, the number of non-expert's contents increased. But non-expert's contents have a simple media just recorded. For providing actual feeling like effects and actions to non-expert's contents, we suggest Fusion Media Middleware(FMM). The FMM can increase user satisfaction by providing actual feeling. Furthermore, The content changes advanced media that has emotional impression. The FMM for providing actual feeling classify the inputted media as a scene based on MPEG-7. The FMM provide an actual feeling to simple media by inserting effects like a sound, image and text among the classified media. Using the BSD code of MPEG-21, the FMM can link up with inputted media and effects. Through the mapping BSD code the FMM control synchronization between media and effects. In this paper, Using the Fusion Media Middleware, the non-expert's contents express value as multimedia that has an actual feeling. Futhermore, the FMM creates flow of new media circulation.

According to the recent advances of digital encoding technologies and computing power, large amounts of multimedia informations such as image, graphic, audio and video are fully used in multimedia systems through Internet. By this, diverse retrieval mechanisms are required for users to search dedicated informations stored in multimedia systems, and especially it is preferred to use contents-based retrieval method rather than text-type keyword retrieval method. In this paper, we propose a new contents-based indexing and searching algorithm which aims to get both high efficiency and high retrieval performance. To achieve these objectives, firstly the proposed algorithm classifies images by a pre-processing process of edge extraction, range division, and multiple filtering, and secondly it searches the target images using spatial and textural characteristics of colors, which are extracted from the previous process, in a image. In addition, we describe the simulation results of search requests and retrieval outputs for several images of company's trade-mark using the proposed contents-based retrieval algorithm based on wavelet.

In information system research. there has been a strong interest in developing the user-centered interface. Interface metaphors have been regarded as a user friendly device of the information retrieval systems. This study is to discover overall opinions about metaphors and to evaluate the usability of metaphors used in the homepages and retrieval interfaces of academic and public libraries. It is found that some metaphors cause users to confuse because they are similar each others or don\`t have unique meaning and because some have weak relationship between texts and images of metaphors. It is necessary to develop a metaphor model suitable for the a specific interface. This study proposes to develop functional metaphors which can help users easily understand how to operate and remember the procedures, and which are based in user\`s knowledge and experiences. The organizational metaphors of a virtual community also will be considered as a new type of retrieval interfaces.

With recent progress of related multimedia computing technologies, it is necessay to retrieve diverse types of multimedia data based on multi-media content and their relationships. However, different from alphanumeric data, it is difficult to provide relevant multimedia information, be-cause multimedia contents and their relationships are implied in multimedia data. Therefore, in case of a multimedia news service system that is a representative multimedia application, most of new services provide relevant news about text articles and retrieval of multimedia news such as video news or image news are provided independently. In this paper, we present an XML-based multimedia news management system, which provides integrating, retrieval, and delivery of relevant multimedia news. Our data model composed of media object, relationship object, and view object represents diverse types of multimedia news content and semantically related multimedia news. In addition, a proposed view mechanism makes it possible to customize multimedia news, and therefore provides multimedia news efficiently.
