사용자와 상호 작용할 수 있도록 애니메이션으로 만들어진 캐릭터는 튜터, 상품 발표 및 어시스턴트 등과 같이 다양한 분야에서 활용될 수 있다. 캐릭터 에이전트를 사용하여 사용자와 상호작용하는 환경을 개발하는 경우에 캐릭터 에이전트를 감성적 에이전트의 성격을 띠는 형태로 정의하고 이 캐릭터를 웹 브라우저상에서 할 수 있는 언어가 필요하다. 따라서 XML 기술을 사용한 스크립트 언어를 통해서 이 문제점을 해결하고자 한다. XML의 장점은 데이터를 구조적으로 기술할 수 있고 각 데이터들을 손쉽게 얻어서 제어할 수 있다. 따라서 XML을 기반으로 스크립트 언어를 사용하면, 추론 과정에서 표현되는 정보를 구조화시키고, 사용자와의 동시 과정에서 정보의 전달이 용이하고 캐릭터를 표현하는데 손쉽게 다를 수 있다. 따라서 본 연구에서는 XML을 기반으로 캐릭터 에이전트를 위한 스크립트 언어를 개발하고 테스트하는데 목적을 둔다.

Robotic motion is designed by the rotation and the translation of multiple joint coordinates in a three-dimensional space. Joint coordinates are generally modeled by homogeneous transform matrix. However, the complexity of three dimensional motions prefers the visualization methods based on simulation environments in which models and generated motions work properly. Many simulation environments have the limitations of usability and functional extension from platform dependency and interpretation of predefined commands. This paper proposes the web-based three dimensional simulation environment toward high user accessibility. Also, it covers the small size web server that is linked with Python script. The non linearities of robot control apply to verify the computing efficiency, the process management, and the extendability of user scripts.

The method of effectively merging XML documents becomes necessary, as the use of XML is popular and the collaborative editing is required in the areas such as office documents and scientific documents editing works. As a solution to this problem, in this paper we present a theoretical framework for merging individual editing works by muli-users to a same source document. Different from existing approaches which merge documents themselves when they are merged, we represent editing works with a series of edit operations applied to a source document, which is called a edit script, merge those edit scripts by multi-users, and apply the merged one to the source document so that we can achieve the same effect of merging documents. In order to do this, assuming edit scripts based on insertion and deletion edit operations, we define notions such as static edit scripts, the intervention between edit scripts and the conflict between the ones, then propose the conflict conditions between edit scripts and the method of adjusting edit scripts when merged. This approach is effective in reducing network overhead in distributed environments and also in version management systems because of preserving the semantics of individual editing works.

In this paper, we suggested an avatar control technique using the high-level behavior. We separated behaviors into three levels according to level of abstraction and defined layered scripts. Layered scripts provide the user with the control over the avatar behaviors at the abstract level and the reusability of scripts. As the 3D environment gets complicated, the number of required avatar behaviors increases accordingly and thus controlling the avatar-object behaviors gets even more challenging. To solve this problem, we embed avatar behaviors into each environment object, which informs how the avatar can interact with the object. Even with a large number of environment objects, our system can manage avatar-object interactions in an object-oriented manner Finally, we suggest an easy-to-use user interface technique that allows the user to control avatars based on context menus. Using the avatar behavior information that is embedded into the object, the system can analyze the object state and filter the behaviors. As a result, context menu shows the behaviors that the avatar can do. In this paper, we made the virtual presentation environment and applied our model to the system. In this paper, we suggested the technique that we controling an the avatar control technique using the high-level behavior. We separated behaviors into three levels byaccording to level of abstract levelion and defined multi-levellayered script. Multi-leveILayered script offers that the user can control avatar behavior at the abstract level and reuses script easily. We suggested object models for avatar-object interaction. Because, TtThe 3D environment is getting more complicated very quickly, so that the numberss of avatar behaviors are getting more variableincreased. Therefore, controlling avatar-object behavior is getting complex and difficultWe need tough processing for handling avatar-object interaction. To solve this problem, we suggested object models that embedded avatar behaviors into object for avatar-object interaction. insert embedded ail avatar behaviors into object. Even though the numbers of objects areis large bigger, it can manage avatar-object interactions by very efficientlyobject-oriented manner. Finally Wewe suggested context menu for ease ordering. User can control avatar throughusing not avatar but the object-oriented interfaces. To do this, Oobject model is suggested by analyzeing object state and filtering the behavior, behavior and context menu shows the behaviors that avatar can do. The user doesn't care about the object or avatar state through the related object.

Movie stories can be retrieved efficiently by analyzing a script, which is a blueprint of the movie. Although the movie script is described in the formatted structure of Final Draft, it is hard to restore the type without analyzing the story of the sentences since the scripts open on the website are mostly broken. For this purpose, it is necessary to develop and provide the web-based script analysis software so that users collaboratively and freely check and correct the errors in the results after automatically parsing the script. Hence, in this paper we suggest the structure of the web-based collaborative script analysis platform that enables users to modify and filter the type error of the script for high level of film data accumulation and performance evaluation for the implementation results is conducted. Through the experiment, accuracy of automatically parsing appears to be 64.95% and performance of modification by collaboration showed 99.58% of accuracy of parsing with errors mostly corrected after passing through 5 steps of modification.

The script of multimedia authoring tool must be able to define the basic events, represent the special function of an object and change the entire system dynamically. In this paper, we design and implement a script interpreter that defines the properties and events of various multimedia objects and executes them, and describe the analysis of script source, the management of execution table, and the method for storing the script information to the objects and executing it according to the user's events.

Through the convergence of Internet technology and various information technologies, it is possible to collect and process vast amount of information and to exchange various knowledge according to user's personal preference. Especially, there is a tendency to prefer intimate contents connected with the user's preference through the flow of emotional changes contained in the movie media. Based on the information presented in the script, the user seeks to visualize the flow of the entire emotion, the flow of emotions in a specific scene, or a specific scene in order to understand it more quickly. In this paper, after obtaining the raw data from the movie web page, it transforms it into a standardized scenario format after refining process. After converting the refined data into an XML document to easily obtain various information, various sentences are predicted by inputting each paragraph into the emotion prediction system. We propose a system that can easily understand the change of the emotional state between the characters in the whole or a specific part of the various emotions required by the user by mixing the predicted emotions flow and the amount of information included in the script.

본 논문은 현재 컴퓨터 사용자들에게 많은 피해를 입히고 있는 악성 스크립트 코드에 대한 탐지기법을 제시하고자 한다. 스크립트 언어는 타 언어에 비해서 단순하며, 상위 수준의 언어로 작성된 소스를 직접 분석가능하기 때문에 기존의 이진 파일 형태의 바이러스 비해 정적 분석 기법 적용이 용이하다. 제안하는 탐지 기법은 기존의 스코어링 방식을 기반으로 한 패턴 매칭과는 달리 스크립트가 수행하는 악성 행위의 분석을 통해 행위 패턴을 생성하고, 이 패턴들을 정적 분석 기법을 통해 패턴간의 관계 분석을 통해 보다 확실한 악성 행위를 탐지하여 스크립트에 포함된 악성행위들을 보고한다. 기존 대부분의 바이러스 탐지 도구들은 이미 알려진 바이러스들만을 탐지 할 수 있다. 정적 분석 기법을 이용한 악성 스크립트 탐지 방법은 악성 행위 별 패턴 존재 여부를 판단하므로 이미 알려진 바이러스는 물론 알려지지 않은 바이러스를 탐지 할 수 있는 방안을 제시한다.

사용자와 개발자의 컴퓨터 환경은 시간이 지날수록 객체지향 환경으로 변화하고 있다. 초기에는 소프트웨어 개발단계에 객체지향 기술이 적용이 되었으나, 최근에는 운영체제와 같은 사용환경에도 기술이 적용되고 있다. 또한 과거 운영체제에서는 순차적이고 반복적인 작업을 쉽게 하기 위해 스크립트 언어를 많이 사용하였으나 이와 같은 스크립트 언어는 객체지향 방법이 적용된 사용환경에서는 적합하지 않은 무제점이 있다. 따라서 객체지향 기술을 사용할 수 있는 스크립트 언어에 대한 요구가 증가하였고, 자바스크립트도 그런 요구의 일부를 만족시키는 언어이다. 그러나 현재까지 사용되는 자바스크립트 해석기는 시스템에서 제공되는 객체만이 사용가능했으며 언어명세에도 기능확장을 위한 방법이 정의되어 있지 않다. 따라서 추가적인 기능확장을 위한 방법이 제공되지 않는 단점이 있다.
