A multi-story can be generated by the interactions of users in the interactive storytelling system. In this paper, I suggest narrative structure and corresponding Storytelling Markup Language and implement the system that processes a story presented using this language. This research will be basis of making an authoring tool for interactive storytelling. It can be used to make a story tool and story presentation tool using text, image, animation with user interaction.

In this study, the wrapper database description language and model is suggested to collect product reviews from Korean shopping malls with multi-layer structures and are built in a variety of web languages. Above all, the wrapper based web crawlers have the website structure information to bring the exact desired data. The previously suggested wrapper based web crawler can collect HTML documents and the hierarchical structure of the target documents were only 2-3 layers. However, the Korean shopping malls in the study consist of not only HTML documents but also of various web language (JavaScript, Flash, and AJAX), and have a 5-layer hierarchical structure. A web crawler should have information about the review pages in order to visit the pages without visiting any non-review pages. The proposed wrapper contains the location information of review pages. We also propose a language grammar used in describing the location information.

Gwae(卦氣) theory was one of the main theoretical foundation of yiology in the Han(漢)-dynasty. It was based on the concept that the trigram or hexagram of the book of change corresponds to the seasonal point such as 24 solar terms in one year, so there was so much influence from astronomy and divination system of that time in the development of theoretical principle of Gwae(卦氣) theory. Since Han(漢) Dynasty, the theoretical method such as Gwae(卦氣) theory that correlates the astronomy and divination system with the book of change, had become one of the main academic thoughts throughout the entire history in China, and it was also like that in medicine. Nevertheless there still exists the skeptical sights that Gwae(卦氣) theory was not a part of orthodox yiology, that had been developed by Confucian scholar and had also been recognized as the right path to the study of the book of change. Nowadays because of the new opportunity such as the excavation of the ancient silk script, this kind of controversy has moved on its another step. With regard to this problem, this article will treat the current thoughts about the Gwae(卦氣) theory and think about the substantial basis of each point of view.

As a recent dominant web trend, mobile first strategy has been emphasized, and interests with respect to responsive web that provides effective methodology to various mobile devices and their display resolution are also increasing. However, it is an early adoption stage in web mapping for geo-spatial applications. This study is to present some practical examples of layouts using responsive web technologies linked to geo-spatial open platform. Suggestive consideration points for further application of responsive web to geo-spatial services are presented. On test implementing, HTML5, JavaScript, and CSS3 were used, and web mapping processing using OpenLayers was performed. It is expected that responsive web applications for contents derived from geo-spatial information or location data increase.

Such as closed caption, ancillary data, electronic program guide(EPG), data broadcasting, and etc, increased data for service convenience cause to degrade video quality of high definition contents. This article propose a method to transfer the closed caption data of video contents without video quality degradation. Video quality degradation does not cause in video compression by the block image insertion of caption data in DTV essential hidden area. Additionally the proposed methods have advantage to synchronize video, audio, and caption from preinserted script without time delay.

엔진을 도입하여 개발할 경우 단지 하부 구조를 구현하지 않았을 뿐, 엔진 내용을 이해할 정도의 수준이 되어야 한다는 것이다. 그러므로 게임 업계에서는 양질의 게임을 개발하기 위해서 여전히 고급 프로그래머를 필요로 하고 있으며, 이러한 부분은 여전히 개발비 상승에 영향을 미치고 있다. 그러므로 프로그램을 이해하는 기획자 수준에서도 게임을 개발할 수 있는 좀 더 상위 개념의 개발 방법의 필요성이 대두되고 있다. 본 논문에서는 이러한 문제를 해결하기 위해 스크립트를 이용하여 게임게임 전체 관리 부분, 모델의 AI부분 카메라 조작 부분으로 게임을 구성할 수 있도록 하였다. 그리고 스크립트 언어는 2 계층의 구조를 갖고 있으며, 하부 계층은 직접적으로 엔진을 제어하게 되어있다. 그러나 스크립트의 목표는 직접적인 엔진 제어를 줄이는 추상화작업을 목표로 하기 때문에 이를 추상화한 상부계층의 스처립트 언어를 설계하여 하부계층의 엔진제어 모듈로 변환하도록 하였다. 따라서 본 논문에서는 게임엔진을 직접적으로 모델링 하지 않고 개발하기 위한 추상화된 상위 단계의 스크립트 언어를 이용하여 기획단계예서 게임을 구성해 볼 수 있으며, 직접적으로 하부구조의 엔진 구현 및 엔진의 내용을 잘 이해할 정도의 수준이 아니더라도 스크립트언어를 이용하여 게임을 개발할 수 있다.

기존의 HTML의 경우 미디어 재생, 3D 그래픽 처리, 웹 소켓 통신 등을 위해서는 Silverlight나 Active-X와 같은 비 표준 플러그인을 설치해야만 구현할 수 있었다. 하지만, 차세대 웹 표준인 HTML5에서는 별도의 플러그인 설치 없이 자바스크립트의 신규 기능만으로 미디어 재생 등과 같은 동적인 기능을 구현할 수 있다. 이처럼 HTML5에서 자바스크립트 기능이 강화됨에 따라 이를 악용한 신종 사이버 공격의 위협이 증가 하고 있다. 기존의 악성 코드 공격과는 달리 사용자 단말에 어떠한 감염도 없이, 악성 스크립트를 삽입한 웹 페이지 접속만으로 악성 행위를 유발하기 때문에 기존의 보안기술로는 탐지에 한계가 존재한다. 이에 본 논문에서는 로컬 프록시를 활용하여, 사용자 단말에서 송/수신되는 HTTP 트래픽을 수집하고, 이를 분석하여, 악성 자바스크립트를 탐지 및 차단하고, 나아가서 난독화 된 악성 자바스크립트를 탐지하는 방법을 제안하고자 한다.

약동학 지표를 구할 시 활용되는 비구획 분석을 Edison system에 적용하여 테오필린(Theophylline)과 인도메타신(Indomethacin) 데이터에 대한 분석을 실시하였다. 각각의 데이터에 대해 Edison 엡 내에서 농도-시간 곡선에 대한 그래프를 다양한 방식으로 구현할 수 있었으며, 계획한 R script를 통해 도출된 결과에서도 현재 임상적으로 가장 널리 쓰이는 비구획 분석방법 소프트웨어와 동일한 값임을 확인하였다. 또한 실제 비구획 분석보다 한 단계 더 복잡한 분석에 대해서도 실제 구현 가능함을 확인하였다. 이를 통해 앞으로 다양한 약동학적 분석방법을 Edison system 안에서 구현하고 활용할 수 있을 것으로 기대된다.

Along with the advance of digital technology, various methods are adopted for capturing the 3D animating data. Especially, in 3D animation production market, the motion capture system is widely used to make films, games, and animation contents. The technique quickly tracks the movements of the actor and translate the data to use as animating character's motion. Thus the animation characters are able to mimic the natural motion and gesture, even face expression. However, the conventional motion capture system needs tricky conditions, such as space, light, number of camera etc. Furthermore the data acquired from the motion capture system is frequently corrupted by noise, drift and surrounding environment. In this paper, we introduce the post production techniques to stabilizing the jitters of motion capture data from the low cost handy system based on Kinect.

The procedure of optimum design is consist of a system analysis module, an optimum design module and an optimizing method module. In this paper, the method to connect the system analysis module with the optimizing method module using the self script language of OPERA has been provided. Optimum design for a magnet whose central field must be 27 has been carried out with the presented method. OPERA Pre/Post-processor has been used as a system analysis module and mixed decent/gradient method as an optimizing method.
