A nonlinear story is generated through the interactivity with users using the interactive storytelling system. In a play or movie, audiences can watch one scene at a time, and in order to watch next scene, they should wait for the end of current scene. In the real world, however, various events can simultaneously happen at different places, and even those events performed by characters may dramatically affect the flow of the story. This paper suggests Constraint Based narrative structure to create such story, known as "Simultaneous Story Arcs", and "Multi Viewpoint" to simultaneously lead the direction of the stories in each place.

웹 어플리케이션은 생명 주기가 짧고, 마르고 정확한 개발이 요구되므로 모델링 단계에서의 요소 분류 및 요소간의 제약조건을 정의할 필요가 있다. 이에 본 연구에서는 각 프레임과 페이지를 그 성격에 따라 집합 프레임과 구조 프레임, 내용 페이지와 구조 정보 페이지로 분류, 이를 바탕으로 요소간의 관계를 정의하였다. 웹 응용 모델링의 요소 분류를 통해 그에 따른 제약 조건을 서술할 수 있는데, 이를 통해 사소한 예측할 수 있는 오류를 피할 수 있고, 웹 응용의 기본적인 테스트 케이스로도 사용할 수 있다.

This paper describes an Adaptive Context-aware Service (ACS) using Model Driven Architecture (MDA)-based Service Creation Environment (SCE) on PARLAY X based service delivery platform in ubiquitous computing environments. It can be expected that both the context-awareness and adaptation in ubiquitous computing environments will be deployed. But the existing context-aware middleware lacks in considering adaptation. Therefore, the object of this paper is to support the architecture and the Application Programming Interface (API) of the network service for both the context-awareness and adaptation in ubiquitous computing environment. ACS is to provide users with the adaptive network service to the changing context constraints as well as detecting the changing context. For instance, ACS can provide users with QoS in network according to the detected context, after detecting the context such as location and speed. The architecture of ACS is comprised of a Service Creation Environment (SCE), Adaptive Context Broker and PARLAY gateway. SCE is to use Context-based Constraint Language (CCL) for an expression of context-awareness and adaptation. Adaptive Context Broker is to make a role of the broker between SCE and PARLAY G/W. PARLAY G/W is to support API for PARLAY X-based service delivery platform.
