This paper proposes two methods for the construction of job offer and job hunting information in order to supply an environment that can easily connects to job hunting information. First, the database expansion, category rules and ERD(Entity Relation Diagram) are designed for the construction of job hunting site with real example. Second, the prime number labeling rules are designed for the strong intimacy of label rules. Therefore, according to using the systematic and regular rules when we design and construct a database, the consistency and efficiency are improved in the database being constructed and being operated. And the convenience of application program development and operation are easily provided. In addition, the proposed code-expansion rule can be defined and be standardized in the domestic and foreign job offer and job hunting information provision agency.

In this paper, we suggest the active multi-agent middleware for the sensor network application. For this, firstly we design and implement the active rule based mobile agent middleware. The mobile agent in the proposed system visits the destination sensor nodes according to the migration list offered by the meta table in the name space of the naming agent, acquires and transmits sensor data according to the purpose and needs through the active rules, and directly executes the actions corresponding to the optional events(changed sensor data and/or time etc.). And then, we show the potential applicability of the active rule based mobile agent middleware in various active sensor networks through the interaction with the rule base system and context database system.

이 논문에서는 이동로봇의 자유로운 배회 및 목적지 찾기 행동을 위한 진화형 퍼지 제어기의 설계 방법을 제안 한다. 전체 실험공간을 장애물과 충돌없이 자유롭게 움직이기 위해서 진화연산 알고리즘을 이용한 퍼지규칙과 소속함수의 자동생성을 거친 뒤 이를 통해 전체 지도정보를 구축한다. 여러 시스템에서 응용되는 퍼지 제어기는 일반적으로 시스템을 잘 이해하고 있는 전문가로부터 구축되어 사용되어진다. 그러나 사람의 지식과 경험은 간혹 알려진 범위 내에서란 완벽하게 작동하기 때문에 그 범위를 벗어나면 오류를 범할 수 있다. 이러한 알려진 해법외의 새로운 규칙과 제어 방법을 찾기 위하여 유전 알고리즘을 이용한 퍼지규칙과 소속함수를 구축하려는 시도가 많이 이루어지고 있다. 이 논문에서도 유전 알고리즘을 이용하여 이동로봇의 퍼지 제어기에 사용된 규칙과 소속함수의 최적화를 통해 견고한 퍼지 제어기를 설계한다. 이를 통해 구축된 지도정보는 로봇의 Deliberative한 행동을 위해 사용되며, Fuzzy-GA 제어기는 센서기반 Reactive 시스템에서 이용된다. 전체 실험환경의 구성부터 제안한 이동로봇 퍼지 제어기 구축과 지도 구축작업을 컴퓨터 시뮬레이션을 통해 검증하였다.

A new design method for multi-functional pull-down menu based on stacking rules is proposed. The importance of a design point of view has been emphasized in many previous studies on web navigation. Taking technical aspects with an emphasis on programming techniques into consideration in this paper, multiple elements, which are used for constructing main menu of the pull-down menu, are capable of performing their unique functions independently in addition to basic classification function by disposing them to separated layers using stacking rules. Furthermore, the improvement of visual effects and efficiency for information navigation can be expected by implementing submenu selection-bar using animation techniques and function to automatically search submenu item. Finally, the effectiveness of the proposed method is identified by implementing multi-functional pull-down menu using CSS and jQuery.

In this paper, we analyze the associated rule based deductive algorithm which creates the rules automatically for intrusion detection from the vast packet data. Based on the result, we also suggest the deductive algorithm which creates the rules of intrusion pattern fast in order to apply the intrusion detection systems. The deductive algorithm proposed is designed suitable to the concept of clustering which classifies and deletes the large data. This algorithm has direct relation with the method of pattern generation and analyzing module of the intrusion detection system. This can also extend the appication range and increase the detection speed of exiting intrusion detection system as the rule database is constructed for the pattern management of the intrusion detection system. The proposed pattern generation technique of the deductive algorithm is used to the algorithm is used to the algorithm which can be changed by the supporting rate of the data created from the intrusion detection system. Fanally, we analyze the possibility of the speed improvement of the rule generation with the algorithm simulation.

As a modeling method where the merits of fuzzy inference system and evolutionary computation are put together, evolutionary fuzzy modeling performs global approximate optimization. The paper proposes fuzzy clustering as fuzzy rule generation process which is one of the most important steps in evolutionary fuzzy modeling. With application of fuzzy clustering into the experiment or simulation results, fuzzy rules which properly describe non-linear and complex design problem can be obtained. The efficiency of evolutionary fuzzy modeling can be improved utilizing the membership degrees of data to clusters from the results of fuzzy clustering. To ensure the validity of the proposed method, the real design problem of an automotive inner trim is applied and the global approximation is achieved. Evolutionary fuzzy modeling is performed for several cases which differ in the number of clusters and the criterion of rule selection and their results are compared to prove that the proposed method can provide proper fuzzy rules for a given system and reduce computation time while maintaining the errors of modeling as a satisfactory level.

BPEL is a standard executable language for specifying actions within business processes with Web services. BPEL workflow requires rule engine to describe application process in BPEL, as the requirements increase. It is needed to develop new BPEL's engine or modify BPEL's engine in order to add the functionality of rules to BPEL engines, but this method is not easy to implement and it requires very high cost. In this paper, we present an R4BPEL document, which uses the original BPEL grammar and includes a rule document. With this method, it is possible to build rule-based BPEL environment easily by adding web services with rules and R4BPEL document analyzer to the general-purpose Web services. In this paper, we campared a BPEL's document in proposed system with a BPEL's document in the existing system. And we demonstrated the simplicity of the rule-based system.

객체 지향 소프트웨어 개발 방법론의 하나인 통합 모델링 언어인 UML은 OMG에 의하여 표준 방법론으로 받아들였다. 본 연구팀에 개발한 UML 그래픽 편집 도구를 이용하여서 소프트웨어를 개발하는 과정에서 발생하는 설계 정보는 모델 관련 정보와 뷰에 관한 정보들을 관계형 데이터베이스에 저장 관리된다. 이들을 Web 통해서 UML 설계 정보의 관리와 공유하기 위해서 UML 설계 정보를 미리 정의한 XML DTD를 이용하여 XML 파일로 변환한 후에 웹 상에서 이를 개발자와 개발 도구들 간에 교환하여 공유할 수 있는 변환 규칙을 제안한다.

EDI is basically the concept of computer-to-computer exchange of messages relating to various types of activities or business areas, such as banking, trade, medicine, publishing, etc. Therefore, security, reliability and special functionality will be implicit requirements of EDI systems. We will design access control model to content security of these requirements. Access controls in information systems are responsible for ensuring that all direct access to the entities occur exclusively according to the access modes and rules fixed by security policies. On this paper, security policies for access control model are presented from the viewpoints of identity-based, rule-based, role-based policy. We give a design of access control model for secure EDI service based on the derived access control rules and operations to enforce the defined security policies. The proposed access control model provides integrity, confidentiality and a flow control of EDI messages.
