테스터의 간섭없이 테스트를 수행할 수 있는 새로운 테스트 도구인 테스트 에이전트 시스템을 구현하였다. 이 시스템에서 테스터는 테스터 이름, 테스트 시간을 입력하고, 테스트 대상을 선택 후, 그 밖에 테스트에 필요한 정보를 입력하고 나면 테스트 에이전트 시스템이 스스로 테스트를 수행한 후 각 테스트 레벨에 대한 테스트 항목의 테스트케이스와 Quality 측정치를 테스트결과로 받아 볼 수 있다. 이 테스트 에이전트 시스템은 3개의 에이전트로 구성이 되어 있고 각 에이전트들은 에이전트의 특성인 자율성, 사회성, 지능성을 가지고 있다. 특히 지능성을 나타내 주는 것을 규칙 기반 시스템을 이용하여 구현하였다. 'User Interface Agent'에는 '리그래션 테스트 대상 판단 규칙'과 'Test History 크기 관리 규칙'이 있고, 'Test Case Selection '||'&'||' Testing Agent'에는 테스트케이스를 선택하는 데에 적용하는 '중복성 제거 규칙'과 '일관성 있는 테스트케이스 선택 규칙'이 있다. "Regression Test Agent'에서는 리그래션 테스트 관련 항목 찾는 규칙'이 있어 각 에이전트들의 지능성을 뒷받침해 준다. 본 논문에서는 각 규칙들을 술어 논리로 표현하여 제시하였고, 구현한 테스트 에이전트 시스템의 Prototype을 기술한다.

Advanced Intelligent Network(AIN) and X.500 directory service have similarity in between. X.500 capabilities and the requirements for the Service Control Function(SCF) to Service Data Function(SDF) in AIN. As an interface, SCF can be mapping as a Directory User Agent(DUA) and SDF can be mapping as a Directory System Agent(DSA). Based on the concepts, X.500 directory can be applied to AIN. In this paper we suggest to apply the X.500 DSP to the SDF/SDF interface to perform a distribution function. Also we show that the SCF-SDF/SDF-SDF relationship can be possible under applying X.500 DAP/DSP within the set of Capability Set 1 (CS1),CS2 and CS3. Finally, based on the above contents, we introduce the designed schematic of AIN SDF Server System for a distributed processing in AIN and design the X.500 schema of Universal Personal Telecommunication(UPT) service for supporting AIN SDF Server.

This study proposes a Natural Language Query Framework (NLQF) on the semantic web to support the intelligent deduction at semantic level. A large number of former researches are focused on the knowledge representation on the semantic web. However, to revitalize the intelligent agent (IA)-based automated e-business contract with human customers, there is a need for semantic level approach to the web information. To enable accessing web information at semantic level, this paper discusses the pattern of complex natural language processing at first, and then the semantic web-based natural language inference in e-business environment. The NL-based approach could help the IAs on the web to communicate with customers and other IAs with more natural interface than traditional HTML-based web information. Therefore, our proposed NLQF will be used in semantic web-based intelligent e-business contracts between customers and IAs.

Electronic commerce system must provide convenient interface, easy and fast searching function, and production information satisfying customers. To do this, many kinds of studies are being advanced actively about electronic commerce system using intelligent agent electronic This paper suggests 2-tier electronic commerce system using intelligent multi agent. We propose a combined reasoning agent system which provides production information satisfying customer's needs using both case-based reasoning and rule-based reasoning. And this system distribute network and sewer system load based on load balancing and 2-tier agent structure. This system can find production information through teaming of rule-based reasoning method and case-based reasoning method. This system can provide the best suitable production information to customers by using combined reasoning agent system. And we can prevent customer's unexpected long waiting causes by network traffic and server load.

In this paper, we describe an implementation of the B-Link bus interface logic for a directory controller and a remote access cash controller in the SCI-based CC-NUMA multimedia server developed by ETRI . The CC-NUMA multimedia server is composed of a number of Pentium III SHV nodes and a SCI interconnection network. To communicate with remote nodes, each node has a CC-Agent which consists of a processor bus interface(PIF). a directory controller(DC), a remote access cash controller(RC), and two SCI 1ink controllers(LCs). The B-Link bus interface logic is developed for a directory controller and a remote access cash controller in order to communicate with a SCI link controller on a B-Link bus. It consists of a sending master controller a receiving slave controller, and asynchronous data buffers. And It performs a self-arbitration, a data packet transmission, a queue allocation, an early terminal ion. and a cut-through data path.

We synthesized a aziridine bonding agent that play an important role in increasing the adhesion property between polymer binders and solid particles. It increases the physical properties of polymer-based propellant. Chemical reaction between two materials increase the interface adhesion. We analyzed and studied the chemical characteristics of the material and physical properties of a liner applied the aziridine bonding agent. We also studied the adhesion property of a liner/propellant applied the aziridine bonding agent. 3M was use as control group. In accordance with US MIS (Missile Interim Specification) we examined the chemical properties. As a result of our study, newly synthesized aziridine bonding agent was as good as quality of 3M HX-868.

An expert network administrator is not always stationed as disasters happen. In that case, it is desirable that a novice administrator is capable of taking part in network recovery operations as well. In this paper, an agent-based network management system in emergency situations is presented. We use the Active Information Resource based Network Management System (AIR-NMS) to relieve the human administrator from parts of her management tasks and present an interface that remotely can control this management system. The effectiveness of the system is demonstrated by experiments using a prototype system.

이제까지 대부분의 다중 에이전트 시스템에서는 에이전트 사회에 속한 모든 응용 에이전트를 작업 요청에 관계없이 처음부터 구동시킨다고 가정하였다. 이러한 에이전트 정적 구동 방법은 에이전트 관리를 단순하게 해주는 이점을 제공하지만 워크플로우 관리나 전자상거래와 같이 매우 많은 수의 에이전트로 구성되는 응용 분야에서는 시스템 과부하와 자원의 낭비 등 많은 문제점을 초래한다. 동적 에이전트 관리는 이에 대한 해결책으로 아주 많은 수의 에이전트를 포함하는 다중 에이전트 시스템에서 현재 수행중인 작업에 관련된 에이전트만을 선별하여 구동시키고, 작업이 끝난 에이전트는 종료시킴으로써 자원의 낭비를 막고 에이전트간의 상호작용 시에 요구되는 에이전트 통신의 복잡도 부담을 감소시키는 효과를 낸다. 본 논문에서는 자바로 에이전트 관리 시스템을 구현하고, 이 관리 시스템을 통해 각기 다른 언어로 개발된 응용 에이전트가 분산된 환경에서 상호 협력을 통해 작업을 수행할 수 있는 기법을 제안한다. 사용자나 다른 에이전트의 요청으로 에이전트를 동적으로 수행시키기 위해 다른 언어로의 확장을 가능하게 하는 Java Native Interface(JNI)를 사용한 기술 및 이러한 이질적인 에이전트간의 원활한 통신을 위해서 KQML 언어 인터페이스를 통한 통신 기능을 제안한다. 이질적 에이전트의 동적 관리를 가능하게 함으로써 다중 에이전트 시스템의 자원 이용 효율성과 확장성을 높이고 다양한 환경 변화에 대한 적응성과 개선된 협동능력을 제공한다.Abstract It has been assumed that all application agents in a multi-agent system are pre-invoked and remain active regardless of whether they are actually used. Although this kind of static agent invocation simplifies the management of agents, it causes several problems such as the system overload and a waste of resources, especially in the areas of the workflow management and the electronic commerce that consist of tens and even hundreds of application agents. A solution for these problems is the scheme of dynamic agent management that selectively invokes only agents that are actually requested and terminates them when they are no longer needed. This method prevents a waste of system resources and alleviates the complexity of agent communications.This paper proposes an agent management system implemented in Java that supports interactions between application agents that are developed using different languages. Dynamic agent invocation is accomplished by Java Native Interface(JNI) that links two heterogeneous methods, and by KQML language interface that facilitates the communications between heterogeneous agents. This scheme of dynamic agent management provides efficient resource usage, easy extensibility, dynamic adaptibility to changes in the environment, and improved cooperation.

This paper presents a Korean conversational agent system in a mobile environment using natural language processing techniques. The aim of a conversational agent in mobile environment is to provide natural language interface and enable more natural interaction between a human and an agent. Constructing such an agent, it is required to develop various natural language understanding components and effective utterance generation methods. To understand spoken style utterance, we perform morphosyntactic analysis, shallow semantic analysis including modality classification and predicate argument structure analysis, and to generate a system utterance, we perform example based search which considers lexical similarity, syntactic similarity and semantic similarity.

This paper presents a robotic agent design and application in the ubiquitous intelligent space. We set up an experimental environment with Bluetooth host, Bluetooth client, furniture and home appliance, and robotic agents. First, the agents basically performed patrol guard to detect unexpected penetration, and to keep home safely from gas-leakage, electric leakage, and so on. They were out to patrol fur a robbery while navigating in a living room and a private room. In this task, we used an area-based action making and a hexagon-based Q-learning to control the agents. Second, the agents communicate with Bluetooth host device to access and control a home appliance. The Bluetooth host offers a manual control to person by inquiring a client robot when one would like to check some place especially. In this exercise, we organize asynchronous connection less (ACL) between the host and the client robots and control the robot maneuver by Bluetooth host controller interface (HCI).
