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.

무선 인터넷 기술의 발전과 함께 이용자 수가 증가하면서 모바일 데이터베이스 응용 프로그램의 수요가 급증하고 있다. 그러나 모바일 데이터베이스 응용에 필요한 사용자 인터페이스와 질의 처리 코드는 대부분 수작업으로 작성되기 때문에 생산성이 낮고 버전 관리에도 많은 시간과 노력이 필요하다.[1] 본 논문에서는 모바일 데이터베이스 응용을 위한 스크립트 생성 도구인 MobileGen을 소개한다. MobileGen은 덕성여자대학교 도서관에서 사용하고 있는 DISCOVER와 같은 실용 데이터베이스들을 구성파일 생성단계, 스크립트 생성단계를 거쳐 응용 데이터베이스 내의 테이블 당 5개의 모바일 스크립트들(Search, Select, Edit, Information, Action)을 생성한다. 생성된 스크립트들은 데이터베이스 연동 및 질의 처리 코드를 포함하고 Action 스크립트를 제외한 나머지 스크립트들은 간단한 폼 형태의 카드 또는 연계된 카드들의 데크들을 생성한다. 따라서 MobileGen은 모바일 데이터베이스 응용의 생산성을 향상시키고 스크립트의 원형인 템플릿을 기반으로 하기 때문에 MobileGen 자체와 생성된 응용의 유지 및 보수를 용이하게 한다. 또한, MobileGen은 상용 생성기들에 비해 관심의 대상인 엔티티 외에 이 엔티티와 직 간접적으로 연관된 모든 엔티티들에 대한 정보를 한 데크에 제공한다.

AFC 시스템은 요금징수단말기로서 버스, 철도, 택시와 같은 다양한 대중교통 수단에서 사용되고 있다. 기존 AFC 단말기는 C, C++ 언어로 작성되었으며, 기능 추가 및 수정을 위해 전체 Application의 실행파일이 전부 교체되어야 했다. 본 논문의 목표는 빈번하게 수정되는 주요 기능들을 스크립트 파일로 모듈화 하는 것이다. 이를 위해 스크립트 파일 기반 시스템을 설계하고 일부기능을 구현하여 시스템을 평가하였다.

PS4(Publishing System Side Script System)는 다량의 정보를 효율적으로 제공하기 위한 정보사이트를 보다 빠르고 효율적으로 구축하기 위해 만들어진 스크립트 시스템이다. PS4는 하나의 템플릿에서 하나의 문서만을 생성하던 점에서 탈피하여 탬플릿 수는 줄이면서 보다 많은 문서를 작성할 수 있도록 개발되었다. PS4를 사용하면 템플릿을 최소화하며, PS3(Publishing System Side Script)를 이용하여 서비스 시스템의 자원 사용 및 중복 작업을 최소화 할 수 있다. 또한 데이터베이스와의 연동을 통하여 자료를 효율적으로 관리할 수도 있다.

JavaScript is one of the most popular languages to develope web sites and web applications. Since applicationss written in JavaScript are sent to clients as the original source code, they are easily exposed to plagiarists. Therefore, a method to detect plagiarized JavaScript programs is necessary. The conventional program dependency graph(PDG) based approaches are not suitable to analyze JavaScript programs because they do not reflect dynamic features of JavaScript. They also generate false positives in some cases and show inefficiency with large scale search space. We devise a JavaScript specific PDG(JS PDG) that captures dynamic features of JavaScript and propose a JavaScript plagiarism detection method for precise and fast detection. We evaluate the proposed plagiarism detection method with experiment. Our experiments show that our approach can detect false-positives generated by conventional PDG and can prune the plagiarism search space.

This paper proposes a method to generate test cases and test scripts from software requirements written in a controlled natural language, which helps develop reliable embedded software. In the proposed method, natural language requirements are written in a controlled language, the requirements are parsed and then inputs, outputs and operator data are extracted from the requirements. Test cases are generated from the extracted data following test case generation strategies such as decision coverage, condition coverage or modified condition/decision coverage. And then the test scripts, physical inputs of the test cases are generated with help of the test command dictionary. With the proposed method, it becomes possible to directly check whether software properly satisfies the requirements. Effectiveness of the proposed method is verified empirically with an requirement set.

As Internet has grown rapidly and been more complex by technology in connection with Web and requirement of business, qualify and reliability of Web application are getting important. It is necessary to study about testing method along with design technique specially in Web application. This paper explains automation method of user interface test to make test cases about user input form with HTML pages using by built-in browser objects. Examples shows the possibility of testing automation with Javascript objects get mapped. Overhead of writing Javascript can be reduced by making script generator. Generated test scripts are repeatedly used in regression testing Web-based application.

The demand for mobile database applications has been rapidly increased with the growth of mobile users and the development of wireless Internet technology. But the productivity of mobile applications is low and it takes much time to manage the versions of applications because the user interface and query processing code of applications is manually written. In this paper, we describe the design and implementation of the MobileGen that is a script generator for mobile database applications. The generated scripts enhance mobile application productivity by providing the code for operating with a database and processing user queries. Each script provides a corresponding deck that is a set of related cards as user interface. The MobileGen supports easy version management of generated applications and the MobileGen itself because it is based on the templates that are frameworks for scripts. Moreover, the MobileGen provides not only the interested entity but also the entities that are related directly and indirectly with the interested entity unlike the most commercial mobile script generators.

This paper proposes Visual Script Language which can direct a type of motion to 3D human model and create by dragging gesture like as we can express a certain meaning with hand gestures. Traditional motion control technique of articulated figures such as human needs a complex task that draws on highly developed human skills. So it will reduce the amount of motion specification to provide the motion control method that allow users to describe characters' motion at the higher level abstraction. Visual script is the visual gestures to direct various human motions, so users can express the spatial attributes of a motion such as the path of moving with high-level concepts if they use visual script. And we can show that it is possible to control the motion of human model directly and intuitively by development of 3D human motion control system based on visual script.
