Nowadays, the web service was based on composing the e-business and distributed computing environment. But existing workflow management systems have many problems with the interoperability between companies because they are made before most web services. For these problems, the workflow based composition language such as the Business Process Execute Language for Web Services (BPEL4WS or BPEL) appeared in expressing the web service composition. In this paper, we present an event based rule management system architecture that executes automatically the BPEL using the Event-Condition-Action (ECA) rules. The event based rule management system consists of the event manager, rule manager, and Jess. The Jess is the part of executing and deciding the condition.

Dispatching rule plays an important role in a hybrid flow shop. Finding the appropriate dispatching rule becomes more challenging when there are multiple criteria, uncertain demands, and dynamic manufacturing environment. Using a single dispatching rule for the whole shop or a set of rules based on a single criterion is not sufficient. Therefore, a multi-criteria decision making technique using 'the order preference by similarity to ideal solution' (TOPSIS) and 'analytic hierarchy process' (AHP) is presented. The proposed technique is aimed to find the most suitable set of dispatching rules under different manufacturing scenarios. A simulation based case study on a PCB manufacturing process is presented to illustrate the procedure and effectiveness of the proposed methodology.

The traditional approaches of association rule mining have relied on high support condition to find interesting rules. However, in some application such as analyzing the web page link and discovering some unusual combinations of some factors that have always caused some disease, we are interested in rules with high confidence that have very low support or need not have high support. In these cases, the traditional algorithms are not suitable since it relies on first satisfying high support. In this paper, we propose a new model, CP(Confidence Pattern)-Tree, to identify high confidence rule between 2-items without support constraint. constraint. In addition, we discuss confidence association rule between two more items without support constraint.

Consider a tetrhedron is composed of six dihedral angles .phi.(i=1,2..., 6), and a vertex of a tetrahedron is also three dihedral angles. It will assume that a vertex A, for an example, is composed of there angles definded such as .alpha..betha. and .gamma. !. then there is a corresponding angle can be given as .phi1.,.phi2.,.phi3.. Here, in order to differentiate between a conventional triangle and dihedral angle, if a dihedral angle degined in this paper is symbolized as .phi..LAMBDA.,the value of cos.theta.of .phi./sab a/, in a trigonometric function rule,can be defined to tecos.phi..LAMBD/sab A/., and it is defined as a tetradedral cosine .phi. or simply called a tecos.phi.. Moreover, in a simillar method, the dihedral angle of tetrahedron .phi..LAMBDA. is given as : value of sin .theta. can defind a tetra-sin.phi..LAMBDA., and value of tan .theta. of .phi..LAMBDA. is a tetra-tan .phi..LAMBDA. By induction it can derive that a tetrahedral geometry on the basis of suggesting a geometric tetrahedron

This paper deals with rule extraction from data using rough set theory. We construct the rule base in a hierarchical granulation structure by applying core as a classification criteria at each level. When more than one core exist, the coverage is used for the selection of an appropriate one among them to increase the classification rate and accuracy. In Addition, a probabilistic approach is suggested so that the partially useful information included in inconsistent data can be contributed to knowledge reduction in order to decrease the effect of the uncertainty or vagueness of data. As a result, the proposed method yields more proper and efficient rule base in compatability and size. The simulation result shows that it gives a good performance in spite of very simple rules and short conditionals.

Recently we started a development of the digital meister expert system for the product design supporting in manufacturing industry. Knowledge representation is of major importance in digital moister expert system. This rule-based expert system-knowledges are designed for a certain type of knowledge representation such as rules or logic. The way in which a rule-based expert system represents knowledge affects the development, efficiency, speed, and maintenance. Eventually, this digital moister system is used to the engineer in manufacturing industry for the process control, production management and system management. In this paper, we propose the digital moister system knowledge representation method for product design supporting in manufacturing industry and we present introduction and contents of rule-based knowledge representation supporting tool.

We often experience complex presence of files within the compute environment. It could be an end-user's desktop environment or a professional part of file management. We would like to suggest one way to manage these different cases of duplicate files. It is a rule-based file management tool, and we want to use it as a tool to consolidate facility management log files. In this paper, we will describe the rule-based file management tools and show examples of how files are managed using them. We are interested in the management of the disaster environment and would like to apply this method to the management of log data related to facilities to be considered in the event of a disaster.

This paper aims to emphasize the necessity of beginning and developing judicial politics in Korea. Law is constitutive of politics, and judicial politics is vital in understanding how politics is influenced by law. Disappointingly, social science in Korea has not recognized the importance of judicial politics. Judicial branch in Korea does not have the capacity to constrain the executive or other government agencies governed by elected officials. The rule of law does not work. Judicial politics has not yet been introduced in Korea, despite its enormous importance in shaping political economy. The rule of law and courts are believed to be the institutional foundation for economic growth. Law embodied in "no one is above the law" is recognized to provide fairness and stability with a democracy. Little attention to judicial politics results in leaving behind a missing link in a polity. The fortification of the rule of law is necessary to make democracy consolidated in Korea, as shown in impeachment of former president Park Geunhae. A new scholarship in Korea on judicial politics is in need to discuss what conditions under which the rule of law is possible and how to make it sustainable.

규칙 기반 패러다임은 복잡한 프로세스를 처리할 수 있는 정형성과 융통성을 제공하기 때문에 여러 프로세스 중심 소프트웨어 공학 환경에 도입되어 왔다 그러나, 기존의 규칙 기반 패러다임을 채택한 시스템들의 경우 프로세스 모델을 작성하거나 이해하기 어렵고 프로세스 모델링 언어가 확장 또는 개선될 때마다 추론 엔진을 수정하거나 최악의 경우에는 새로 개발하여야 한다. 본 논문에서는 빈번히 발생하는 프로세스 변경에 유동적으로 대처할 수 있으며 프로세스 모델을 규칙기반 언어의 사실로 직관적으로 맵핑함으로써 프로세스의 병렬성을 효과적으로 제어할 수 있다는 규칙 기반 패러다임의 장점을 살리면서 기존 규칙 기반 PSEE의 단점인 사용의 용이성과 추른 엔진의 안정성 문제를 해결한 PRAiSE 시스템을 기술한다. PRAiSE에서는 RAiSE라는 그래픽 프로세스 모델링 언어를 제공하며 작성된 프로세스 모델은 규칙 기반 전문가 시스템 도구인 CLiPS로 구현한 프로세스 엔진에 의해 해석되고 실행된다.

This paper proposes the simulator synthesis scheme which is based on the exploration of the total design space in attributed AND-OR graph. Attributed AND-OR graph is a systematic design space representation formalism which enables to represent all the design space by decomposition rule and specialization rule. In addition, attributes attached to the design entity provides flexible modeling. Based on this design space representation scheme, a pruning algorithm which can transform the total design space into sub-design space that satisfies the user requirements is given. We have shown the effectiveness of our framework by (ⅰ) constructing the design space of superscalar processor in attributed AND-OR graph (ⅱ) pruning it to obtain the ARM9 processor architecture. (ⅲ) modeling the components of the architecture and (ⅳ) simulating the ARM9 model.
