Business Rules are formal statements about the data and processes of an enterprise. They present projections of the organization's constraints and ways of working on their supporting information systems. Therefore, their collection, structuring and organization should be central activities within information systems. In an enterprise, business rules are used to represent certain aspects of a business domain (static rules) or business policy (dynamic rules). Hence, regarding problem domains in the organization, business rules are classified into two groups: static and dynamic business rules. The paper introduces a new concept of business rules, Extended Dynamic Business Rule (EDBR) which contains the results of the occurrence of business rule's action. The focus of this paper is in the organizing, defining and modeling of such business rules using Mineau's approach. Mineau's approach is an extension of Sowa's Conceptual Graph theory.

FLC has a good performance for complication system or unknown model by using human linguistic method but many part control design are based on expert knowledge or trial-error method and it is difficult to prove stability and robustness of controller. In this paper we improve this problem by setting fuzzy rules by dividing phase plane of error and rate of error change by switching surface. We can guarantee the stability in nonlinear system, and also in fuzzy PID type controller the complexity of controller design is increased by increasing the number of input variables and defining more range of operation if we want performance of more specific rules, thus we need to fine the method to decrease the number of control rules used in FLC design. In this paper the algorithm is validated by simulation using conventional FLC and proposed method.

다이어그램은 직관성과 간결성을 갖는 장점이 있어 현재의 컴퓨팅 환경에서 많은 분야에 널리 사용되고 있다. 하지만 다이어그램 작성에 대한 표준화된 방법의 부재(不在)로 소프트웨어 상호간의 자료공유가 어렵고 다이어그램 컴포넌트와 규칙을 직접 프로그래밍 해야 하기 때문에 많은 시간과 노력을 필요로 한다. 이러한 문제점을 해결하고자 본 논문에서는 표준화된 문서규약인 XML을 이용해 다이어그램 컴포넌트의 형태와 행위를 정의하는 방법, 다이어그램의 규칙과 의미를 기술하는 방법에 대해 제안하고 제안한 XML 문서가 실행될 수 있는 다이어그램 시스템의 설계 및 구현에 관하여 논의한다. 본 다이어그램 시스템에서는 DML 그래픽 편집기를 제공하여 WYSWYG 방식으로 다이어그램 컴포넌트를 정의하고 자동으로 DML 문서를 생성할 수 있도록 함으로써 더욱 효율적으로 새로운 다이어그램을 개발할 수 있도록 하였다. 뿐만 아니라 DTD를 이용해 다이어그램에 대한 문법을 정의함으로써 문서의 구조를 정의하는 DTD에 대한 의미적 일관성을 유지하였으며 Semantic Definition XML을 이용하여 의미를 기술할 수 있도록 하였다. 또한 다이어그램 시스템에서 다이어그램 문장에 대한 문법검사와 의미실행의 방법은 VPL(Visual Programming Language)의 여러 개념들을 이용하였다.

감정은 사용자의 상호작용을 도와주는 게임요소 중 하나이다. 그동안 게임에서 캐릭터들의 성격이나 감정을 표현하는 방식은 그래픽과 특정행동에 대한 반응 정도로 고려되었다. 하지만 최근 감정연구에 대한 관심이 높아지면서 게임에서도 감정을 다양하게 활용하기 위한 구조화가 필요해졌다. 자율성 에이전트 분야에서는 감정의 활용가능성 연구를 통해 12가지 감정규칙을 정의했다. 본 논문에서는 감정규칙을 게임에 사용되는 용어로 정의하고 확장시켜 게임 감정규칙을 만들었다. 그리고 게임 감정규칙을 사용해 실제 게임 속 캐릭터의 감정을 분석했다. 그 결과 비슷한 장르의 게임에도 각자 다른 게임 감정규칙이 사용되는 것을 볼 수 있었다.

In this paper, it is presented a new technique to the design and real-time implementation of fuzzy control system based-on digital signal processors in order to improve the precision and robustness for system of industrial robot. Fuzzy control has emerged as one of the most active and fruitful areas for research in the applications of fuzzy set theory, especially in the real of industrial processes. In this thesis, a self-organizing fuzzy controller or the industrial robot manipulator with a actuator located at the base is studied. A fuzzy logic composed of linguistic conditional statements is employed by defining the relations of input-output variable of the controller, In the synthesis of a FLC, one of the most difficult problems is the determination of linguistic control rules from the human operators. To overcome this difficult, SOFC is proposed for a hierarchical control structure consisting of basic level and high level that modify control rules.

This paper presents an approach to self-tuning PI control of dynamic plants, based on fuzzy logic application. A fuzzy logic composed of linguistic conditional statements is employed by defining the relations of input-output variables of the controller. In the synthesis of a fuzzy logic controller, one of the most difficult problem is the selection of linguistic control rules and parameters. To overcome this difficulty, self-tuning fuzzy PI controller (STFPIC) with a hierarchical structure in which the fuzzy PI controller is assigned as the lower level and the rule modification and parameter adjustment as the higher level. The rules and parameters are generated by the adjustment of membership function through performance index(PE). In this paper, the algorithm for of the controller performance is estimated by means of computer simulation.

To overcome this difficult SOFC is proposed for a hierarchical control structure consisting of basic level and high level that modify control rules. The proposed SOFC scheme is simple in structure, fast in computations and suitable for implementation of real-time control. Performance of the SOFC is illustrated by simulation and experimental results for robot with low joints.
