Translation errors in the statistical funtions of the Korean Excel 2002 software are analyzed into three categories: Pure translation mistakes; Vague translation; Inconsistent translation. These errors have not been corrected at least for the last ten years and therefore, it is suspicious that the Korean agents for foreign software companies are more interested in marketing with monololy power than in improving quality of their products

Collaborative product commerce(CPC) involves many people working together with heterogeneous and distributed software applications. For such an environment, Workflow Management System(WFMS) can be useful for coordination of people, software agents and processes. It provides diverse services including automatic work muting, project management continuous process improvement and application integration. However, there are some limitations to apply WFMS to CPC environment due to inflexibility and lack of design support facilities. This paper identifies the problems and addresses possible approaches to overcome the difficulties.

In this paper, we propose an agent negotiation algorithm of an intelligent agent system for an active and adaptive multimedia data services in the distributed environment. We describe theEARTS-II system that performs automatic job seeking and job offering operations using intelligentagents without user's intervention. EARTS-II offers best candidate lists as the results to usersthrough negotiation among agents considering conditions given by the users. And according to theresults, the EARTS-II supports real processes of employment, The negotiation algorithm tries tosatisfy all agents in the job market. To test the performance of the algorithm, simulation results arepresented.

This paper addresses the emotion computing model for software affective agents. In this paper, emotion is represented in valence-arousal-dominance dimensions instead of discrete categorical representation approach. Firstly, a novel emotion model architecture for affective agents is proposed based on Scherer's componential theories of human emotion, which is one of the well-known emotion models in psychological area. Then a fuzzy logic is applied to determine emotional statuses in the emotion model architecture, i.e., the first valence and arousal, the second valence and arousal, and dominance. The proposed methods are implemented and tested by applying them in a virtual training system for children's neurobehavioral disorders.

SNMP is a standard protocol for management of networking devices. Nowadays, most computer systems have capability to act as SNMP agents. In this paper, we describe our system monitoring software based on SNMP. It consists of a monitoring server, SNMP agents, and client programs. The monitoring server collects status information from the SNMP agents running on the monitoring target graphical display. We developed two version of clients, Java based standalone program and Web based program. Since most known SNMP packages are too big and heavy, we developed an efficient version of SNMP library for out system monitoring.

Negotiation is a process of reaching an agreement on the terms of a transaction. such as price, quantity, for two or more parties. Negotiation tries to maximize the benefits for all parties concerned. instead of using human-based negotiation. the e-commerce environment provides such an environment as adopting automated negotiation. Thus. choosing agent technology is appropriate for an automatic electronic negotiation platform. since autonomous software agents strive for the best deal on behalf of the human participants. Negotiation agents need a clear-cut definition of negotiation models or strategies. In reality, most bargaining systems embody nearly one negotiation model. In this article. we present a mobile agent negotiation system with reusable negotiation strategies that allows agents to dynamically embody a user's favorite negotiation strategy which can be preinstalled as a component in the system. We develop a prototype system, which is fully implemented in compliance with FIPA specifications, and then. describe the benefits of using the system.

Due to recent growing interest in autonomous software agents and their potential application in areas such as electronic commerce, the autonomous negotiation become more important. Evidence from both theoretical analysis and observations of human interactions suggests that if decision makers have prior information on opponents and furthermore learn the behaviors of other agents from interaction, the overall payoff would increase. We propose a new methodology for a strategy finding process using data mining in autonomous negotiation system; ANSIA(Autonomous Negotiation System using Intelligent Agent). ANSIA is a strategy based negotiation system. The framework of ANSIA consists of three component layers; 1) search agent layer, 2) data mining agent layer and 3) negotiation agent layer. ANSIA is motivated by providing a computational framework for negotiation and by defining a strategy finding model with an autonomous negotiation process.

This paper presents the implementation of an integrated messaging gateway (IMG) based on the open services gateway initiative (OSGi) specification to deliver home messages between home and some telecommunication devices. The IMG has four service agents to support a diverse communication channel. In this paper, we describe a software architecture for a seamless messaging and device layouts in the IMG. And then, we detail each components allowing users to be notified automatically through a cellular phone, a telephone, and the Internet.

컴퓨터 분야에서 에이전트의 개념의 전자 상거래, 정보 검색과 같은 많은 어플리케이션에 응용되어 중요시되고 있지만, 소프트웨어 테스트 분야에 에이전트의 개념이 적용되는 것은 드문 일이었다. 테스트 에이전트 시트템 (TAS)은 에이전트 개념을 소프트웨어 테스트 분야에 적용한 새로운 도구로, 'User Interface Agent', 'Test Case Selection & Testing Agent'그리고'Regression Test Agent'로 구성되어 있다. 이들 세개의 에이전트들은 각각 지능성을 나타내는 규칙들을 가지고 객체 지향 프로세스를 딸라 자율적으로 테스트를 진행한다. 이 시스템은 두 가지 측면에서 장점을 가지고 있다. 첫째는 자율적으로 테스트 진행시켜 테스터의 간섭을 최소화한다는 것이고 둘째는 지능적으로 중복이 없고 일관성이 있는 효율적인 테스트케이스를 선택하여 테스트 시간을 감소시키면서 오류검출능력은 향상된다는 것이다. 본 논문에서는 사례를 중심으로 실행과정을 기술하여 TAS를 구성하는 세 개의 에이전트들의 자율적인 행동으로 테스트가 진행되는 것을 보여 TAS가 테스트의 간섭을 최소화한다는 것을 보인다. 그리고 4가지유형의 실험을 수행하여 테스트 시간의 단축과 오류 검출 효과향상을 기술한다.

In this study, the properties of polyurethane-polydimethylsiloxane (PU-PDMS) hybrid foams containing different types and contents of physical blowing agents (PBAs) were investigated. Two types of blowing agents, namely physical blowing agents and thermally expandable microspheres (TEM), were applied. The apparent density was measured using precisely cut foam samples, and the pore size was measured using image software. In addition, the microstructure of the foam was confirmed via scanning electron microscopy and transmission electron microscopy. The thermal conductivities related to the microstructures of the different foams were compared. When 0.5 phr of the hydrocarbon-based PBA was added, the apparent density and pore size of the foam were minimal; however, the pore size was larger than that of neat foam. In contrast, the addition of 3 phr of TEM effectively reduced both the apparent density and pore size of the PBAs. The increase in resin viscosity owing to TEM could enhance bubble production stability, leading to the formation of more uniform and smaller pores. These results indicate that TEM is a highly efficient PBA that can be employed to decrease the weight and pore size of PU-PDMS hybrid foams.
