In the field of game design, scenarios are essential part. But general-purpose tools for production of game scenarios have not been developed yet. In order to solve these problems, we studied the difference between game scenarios and other scenarios and analyzed scenario UCC(User Created Contents) and created suitable forms of game scenarios. To make OSMU(One Source Multi Use) easier, we use XML-based format of game scenario. To verify the possibility for practical application of XML-based format, we wrote a game scenario with scenario editor that we made and applied it to scenario-based game 'FEEL Online'.

Today, Internet users can easily create and share the digital contents with others through various online content sharing services such as YouTube. So, many portal sites are flooded with lots of user created contents (UCC) in various media such as texts and videos. Estimating popularity of UCC is a crucial concern to both users and the site administrators. This paper proposes a method to predict the popularity of Internet articles, a kind of UCC, using the dynamics of the online contents themselves. To analyze the dynamics, we regarded the access counts of Internet posts as the popularity of them and analyzed the variation of the access counts. We derived a model to predict the popularity of a post represented by the time series of access counts, which is based on an exponential function. According to the experimental results, the difference between the actual access counts and the predicted ones is not more than 10 for 20,532 posts, which cover about 90.7% of the test set.

Nowadays personal users create a variety of multi-media contents and share them with others through various devices over the Internet since the concept of user created content (UCC) has been widely accepted as a new paradigm in today's multi-media market, which has broken the boundary of contents providers and consumers. This paradigm shift has also introduced a new business model that makes it possible for them to create their own multi-media contents for commercial purpose. This paper proposes a tangible virtual studio using augmented reality to author multi-media contents easily and intuitively for personal broadcasting and personal content generation. It provides a set of tangible interfaces and devices such as visual markers, cameras, movable and rotatable arms carrying cameras, and miniaturized set. They can offer an easy-to-use interface in an immersive environment and an easy switching mechanism between tangible environment and virtual environment. This paper also discusses how to remove inconsistency between real objects and virtual objects during the AR-enabled visualization with a context-adaptable tracking method. The context-adaptable tracking method not only adjusts the locations of invisible markers by interpolating the locations of existing reference markers, but also removes a jumping effect of movable virtual objects when their references are changed from one marker to another.

The web is shifting from being a medium in which information is transmitted and consumed, into being a platform in which contents are created, shared, repurposed. Web 2.0 applications are those that make the most of the intrinsic advantages of that platform. This thesis proposed a learning system based on web 2.0 for promoting statistics literacy. For this, I proposed students to create UCC(User Created Contents) data to learn principle of statistics and practical use of statistical data. To examine educational effectiveness of this study, an experimental study was conducted through the education content and method to the subject of one class in the first-grade of university located in OO city. As a result, the student understanded basic principle on statistics and perceived importance of statistics literacy and presented positive responses to statistics. In conclusion, it is confirmed that it is possible to provide effective education for students if the statistics literacy is proposed to proper education method.

This paper introduce a satellite image based blog system built by JeonNam local province. Main goals of this system are as follows : (1)Overcome the static aspect of traditional Web-GIS, (2)Providing a geoUCC generating platform by combining multimedia technology and GIS in a single web environment, (3)Building a two-way Web-GIS through user's participation, (4)Creating a new communicative way between government and citizen by using this system. As a result of the system building, this system enables users to create his/her own UCC(User Created Contents) on high-resolution satellite image and enables users to share his/her own UCC with other system using Web2.0 technology.

최근 인터넷의 발달로 디지털 콘텐츠 및 UCC(User Created Contents) 산업이 발전하고 있다. 그러나 이로 인한 부작용도 많이 발생한다. 대표적인 문제는 디지털 콘텐츠의 무단 불법복제나 무료배포행위이다. 이는 디지털 콘텐츠 산업의 성장과 UCC 제작자의 창작의지 를 저해하여 웹2.0시대의 중심인 양질의 콘텐츠 생산을 방해한다. 본 논문에서는 위의 문제를 해결하기 위하여 멀티미디어 콘텐츠의 경매 시스템 과 경매 프로세스를 제시하였다. 본 논문에서는 멀티미디어 콘텐츠에 중고의 개념을 도입하였다. 특히, 모바일 상에서 경매가 가능하도록 새로운 시스템 구조를 제안하고, 멀티미디어 콘텐츠의 경매거래 프로세스를 새롭게 제안하였다. 시스템의 성능 분석 결과 주요 경매프로세스는 성능 분석 과정을 통하여 $\theta$ (logN) 의 정수 배(m)의 시간을 사용하는 알고리즘임을 소개하고 사용자나 콘텐츠의 양이 폭발적으로 증가하는 경우에도 시스템의 성능에 크게 영향을 받지 않는다는 것을 보인다.

With the development and invention of computer and internet, GIS (Geographic Information System) has provided diverse services to users. Web 2.0, the next generation web, has been developed to create a new business by accumulating and structuring information from many users. The characteristics of Web 2.0 are blog, longtail distribution, SNS, DCC, collective intelligence, and so on. This study proposes a GIS 2.0 service model to maximize the introduction effect and use of GIS by the method that two-way communication and the participation of consumer, characteristics of Web 2.0, are used to build more practical GIS rather than providing spatial information in one-way and simple inquiry oriented way.

Recently mobile service industry has grown very rapidly. In this paper, I investigated the changes in mobile service industry as well as new direction of human life in future global society. Under these changing market conditions, competition has been also changed into global and ecological competition. But compared to the platform initiatives and ecological strategies of global companies, Korean companies' vision of building ecosystems is still unclear. New directions of mobile service industry are smart phone oriented open market, UCC, QPS and cloud computing. As such, I investigate the structure of mobile service ecosystem in order to gain strategic implications and insights in this paper.

본 논문은 사용자제작콘텐츠 (User Created Contents, UCC)를 이용한 가상현실 (virtual reality, VR) 음향 재구성을 위한 스마트폰의 주파수응답 정규화에 관한 연구이다. 서로 다른 스마트폰들로 취득한 음향들을 연결할 때, 부자연스러운 음향이 발생하며, 이것은 주로 스마트폰별로 다른 주파수 응답에 기인한다. 이러한 문제를 해결하기 위하여 스마트폰의 주파수응답을 정규화 하는 과정이 필요하며, 본 연구에서는 심층신경망 (deep neural network)을 이용하는 방법을 제안한다. 심층신경망의 입력은 처리하고자 하는 스마트폰 음향의 스펙트럼이고 출력은 이것과 기준 스마트폰 음향의 스펙트럼과의 비율이다. 실험결과, 서로 다른 스마트폰으로 취득한 음향신호가 연결되었을 때, 객관적 및 주관적 평가를 통해 음향의 자연성이 개선됨을 확인 하였다.
