There is no agreed definition of intelligence. The ability to adapt to the environments is a kind of intelligence. Expert functionally recognize environment using their five senses, and acquire and memorize knowledge necessary for operating machines. Knowledge that they cannot acquire directly is acquired in indirect ways. The purpose of intelligence machines is applying to machines experts' knowledge acquisition process and their skills in operating machine. An agent is an autonomous process that recognizes external environment, exchanges knowledge with external machines and performs an autonomous decision-making function in order to achieve common goals. This paper describes agent application for intelligence machine.

최근 온톨로지를 이용하여 지능형 에이전트의 지능을 구현하는 연구가 주목을 받고 있다. 그러나 온톨로지로 구현한 지능을 효과적으로 사용하기 위해서는 지능의 활용 목적에 적합한 온톨로지 모델의 설계가 필요하다. 본 논문에서는 지능형 에이전트가 특정 사건을 인식하고 반응하는 과정을 단계별로 표현한 '지능형 에이전트의 인지 사이클'을 정의한다. 그리고 온톨로지 기반의 지능형 에이전트를 설계하고, 온톨로지 추론을 통한 지능형 에이전트의 상태 변화, 감정 표현, 지능 확장이 가능한 온톨로지 모델을 제안한다. 또한, Helen이라는 지능형 에이전트를 구현하여 주변 환경과 상황에 따른 내부 상태의 변화를 확인하고 지능 확장의 용이성을 보인다.

Agent-mediated electronic markets have been a grow-ing area of agent research and developmen tin recent year. There exist a lot of e-commerce sites on the In-ternet(e.g. Priceline, com, Amazon, com etc). These e-commerce site have proposed new business models for effective and efficient commerce activity. Intelli-gent agents have been studied very widely in the field of artificial intelligence, For purpose of this paper, an agent can act autonomously and collaboratively in a network environment on behalf of its users. It is hard for people to effectively and efficiently monitor, buy, and sell at multiple e-commerce sites. If we intro-duce agent technologies into e-commerce systems, we can expect to further enhance the intelligence of their support. In this paper, we propose a new coopera-tion mechanism among seller agents based on exchang-ing their goods in our agent-mediated electronic market system. G-Commerce. On G-Commerce, seller agents and buyer agents negotiate with each other. In our model, seller agents cooperatively negotiate in order to effectively sell goods in stock. Buyer agents coopera-tively form coalitions in order to buy goods based an discount proices. Seller agent's negotiation goods. Our current experiments show that exchanging mechanism enables seller agents to effectively sell goods in stock. Also, we present the Pareto optimality of our exchang-ing mechanism.

This study aims to obtain empirical evidence of the absence of testing the effect of professional ethics, emotional intelligence, and internal auditor performance on professional skepticism. According to this study, internal auditors can use professional skepticism to better understand red flag fraud. Questionnaires were used as the research instruments in this study. The participants included 186 auditors. Using structural equation modeling, this study confirms the hypothesis. The results show that the application of professional ethics and emotional intelligence has a positive effect on professional skepticism. The findings show that 1) professional skepticism can improve internal auditors' understanding of the red flags of fraud, 2) professional ethical norms influence how people behave and accomplish jobs, and 3) how constructive findings are produced by an audit procedure that adheres to the requirements of an audit expert, not just an espionage agent trained to infiltrate. As a result, internal auditors' higher performance in performing functions as a building agent rather than a secret agent like intelligence can be attributed to this. This study provides evidence that 1) not only does the use of professional ethics increase professional skepticism, but high emotional intelligence also plays a role, and 2) professional skepticism can improve internal auditors' understanding of red flags of fraud.

In the era of the 4th industrial revolution, the aviation industry is also growing remarkably with the development of artificial intelligence and networks, so it is necessary to study a new concept of crew resource management (CRM), which is required in the process of operating state-of-the-art equipment. The automation system, which has been treated only as a tool, is changing its role as a decision-making agent with the development of artificial intelligence, and it is necessary to set clear standards for the role and responsibility in the safety-critical field. We present a new perspective on the automation system in the CRM program through the understanding of the autonomous system. In the future, autonomous system will develop as an agent for human pilots to cooperate, and accordingly, changes in role division and reorganization of regulations are required.

In Efforts to prevent CFIT accidents so far, have been emphasizing various education measures to minimize the occurrence of human errors, as well as enforcement measures. However, current engineering measures remain in a system (TAWS) that gives warnings before colliding with ground or obstacles, and even actual automatic avoidance maneuvers are not implemented, which has limitations that cannot prevent accidents caused by human error. Currently, various attempts are being made to apply machine learning-based artificial intelligence agent technologies to the aviation safety field. In this paper, we propose a deep reinforcement learning-based artificial intelligence agent that can recognize CFIT situations and control aircraft to avoid them in the simulation environment. It also describes the composition of the learning environment, process, and results, and finally the experimental results using the learned agent. In the future, if the results of this study are expanded to learn the horizontal and vertical terrain radar detection information and camera image information of radar in addition to the terrain database, it is expected that it will become an agent capable of performing more robust CFIT autonomous avoidance.

This paper presents a new approach to solve the pursuit problem based on a univector field method. In our proposed method, a set of eight agents works together instantaneously to find suitable moving directions and follow the univector field to pursue and capture a prey agent by surrounding it from eight directions in an infinite grid-world. In addition, a set of strategies is proposed to make the pursuit problem more realistic in the real world environment. This is a general approach, and it can be extended for an environment that contains static or moving obstacles. Experimental results show that our proposed algorithm is effective for the pursuit problem.

본 논문에서 제안한 Multi Agent Multi Action은 기존의 대화형 시스템 방식인 Single Agent Single Action 구조에 비해 확장성을 갖춘 대화 시스템을 구현하는 방식이다. 시스템을 여러 에이전트로 분할하고, 각 에이전트가 특정 액션에 대한 처리를 담당함으로써 보다 유연하고 효율적인 대화형 시스템을 구현할 수 있으며, 다양한 작업에 특화된 에이전트를 그룹화함으로써 작업의 효율성을 극대화하고, 사용자 경험을 향상 시킬 수 있다.

사회적 감성 에이전트는 인간과 유사한 사회지능(Social Intelligence)을 가지고 있는 에이전트로서, 인간의 감정을 인지 및 학습하고 적응을 통하여 상대방의 감정과 상함에 따라 적절한 반응을 할 수 있는 능력을 가기고 있다. 이 에이전트는 인간이 에이전트를 더 살아 있는 것처럼(Believable) 느끼게 하여, 인간과 컴퓨터간의 상호작용을 도와줌으로써 인간에게 더욱더 개인화되고 적합한 서비스 창출하고 제공할 수 있는 에이전트 모델이다. 본 논문에서는 인간의 사고 과정과 동일한 3단계 사고 작용 모델(Three-Layered Affect Functioning Model)을 통해서, 에이전트가 사용자의 감정과 상황을 인식하여, 지능적 반응이나 행동을 가능하게 하는 프레임워크를 제안한다. 그리고 에이전트의 감정과 상황인식을 위해서는 심리학 모델인 OCC 모델과 결정트리 구성 알고리즘인 ID3를 활용하였다. 이를 통해서 교육, 예술, 연예, 디자인, 의료 등 다양한 분야에서 응용될 수 있는 사회적 감성지능형 에이전트를 개발할 수 있을 것으로 기대 된다.
