Because of the characteristics of the cyber world, such as usefulness, anonymousness, patency, economic performance, rapidness, etc., cyber counseling has great possibility. Because he or she may not meet a consultant directly, a client can expose his/her inside problems or secret personal problems, keeping anonymousness. However, existing cyber counseling has the limit in durability of counseling because target counseling appropriate to a client is impossible and a counseling activity is done by one time counseling. In this paper, we attempt to develop a target cyber counseling system in which target cyber counseling is possible. The system will use a counseling assistance agent who can play the role of a counseling supporter as well as a counselor in the cyber space. If target counseling becomes possible, it can heighten efficiency of cyber counseling because a client is satisfied with the result of counseling and thus counseling activities can be continued.

Streaming Technology can support the real-time playback without downloading and storing multimedia data in local HDD. So, client browser or plug-in can represent multimedia data before the end of file transmission using streaming technology. Recently, the demand for efficient real-time playback and transmission of large amounts of multimedia data is growing rapidly. But most users' connections over network are not fast and stable enough to download large chunks of multimedia data. In this paper, we propose an intelligent IP streaming system based on personalized media service. The proposed IP streaming system enables users to get an intelligent recommendation of multimedia contents based on the user preference information stored on the streaming server or the home media server. The supposed intelligent IP streaming system consists of Server Metadata Agent, Pumping Server, Contents Storage Server, Client Metadata Agent and Streaming Player. And in order to implement the personalized media service, the user information, user preference information and client device information are managed under database concept. Moreover, users are assured of seamless access of streamed content event if they switch to another client device by implementing streaming system based on user identification and device information. We evaluate our approach with manufacturing home server system and simulation results.

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).

Security plays a vital role and is the key challenge in Mobile Ad-hoc Networks (MANET). Infrastructure-less nature of MANET makes it arduous to envisage the genre of topology. Due to its inexhaustible access, information disseminated by roaming nodes to other nodes is susceptible to many hazardous attacks. Intrusion Detection and Prevention System (IDPS) is undoubtedly a defense structure to address threats in MANET. Many IDPS methods have been developed to ascertain the exceptional behavior in these networks. Key issue in such IDPS is lack of fast self-organized learning engine that facilitates comprehensive situation awareness for optimum decision making. Proposed "Intelligent Behavioral Hybridized Intrusion Detection and Prevention System (IBH_IDPS)" is built with computational intelligence to detect complex multistage attacks making the system robust and reliable. The System comprises of an Intelligent Client Agent and a Smart Server empowered with fuzzy inference rule-based service engine to ensure confidentiality and integrity of network. Distributed Intelligent Client Agents incorporated with centralized Smart Server makes it capable of analyzing and categorizing unethical incidents appropriately through unsupervised learning mechanism. Experimental analysis proves the proposed model is highly attack resistant, reliable and secure on devices and shows promising gains with assured delivery ratio, low end-to-end delay compared to existing approach.

현재 컴퓨팅 기술은 유비쿼터스 컴퓨팅 환경에서 컨텍스트 인식을 위한 지능화된 시스템 구조를 요구하고 있다. 컨텍스트를 인식하기 위한 지능화된 시스템은 에이전트를 기반으로 하고 있으며, 사용자를 인식하기 위한 센서의 정보와 서비스를 지원하기 위한 프레임을 필요로 한다. 따라서 본 논문에서는 각 센서와 서비스들을 동적으로 연결하고, 각종 컨텍스트를 안정적으로 지원할 수 있는 3-Tier 컨텍스트 인식 처리 서버/클라이언트 구조를 제안한다. 제안하는 시스템의 구조는 사용자의 상황 정보를 인식하는 클라이언트 계층과 인식된 상황정보를 처리하기 위한 응용처리 에이전트 서버(APAS) 계층, 이 두 계층을 관리하기 위한 관리서버(Management Server)로 구성된다. 또한 이 구조에서는 정교한 서비스를 제공하기 위하여 사용자의 정보는 동적 프로파일로 구성되어 있다.

I propose a personalized digital library system (PDLS) based on an advanced distributed agent platform. The new platform is developed by improving the DECAF (Distributed Environment-Centered Agent Framework) which is one of the conventional distributed agent development toolkits. Also, a mobile ORB (Object Request Broker), Voyager, and a new multi agent negotiation algorithm are adopted to develop the advanced platform. The new platform is for mobile multi agents as well as the distributed environment, whereas the DECAF is for the distributed and non-mobile environment. From the results of the simulation the searched time of PDLS is lower, as the numbers of servers and agents are increased. And the user satisfaction is four times greater than the conventional client-server model. Therefore, the new platform has some optimality and higher performance in the distributed mobile environment.

현재까지 전자상거래는 클라이언트-서버 중심의 상거래가 대다수란 이루고 있다. 상품을 검색하기 위해서도 전자상거래 사이트에 가입하여 검색해야만 한다. 하지만 P2P(Peer To Peer)는 이러한 서버와 클라이언트 중심의 구조를 탈피하여 사용자들간의 직접적인 정보 교환을 가능하게 함으로써 서버확보라는 비용추가 및 서버에 집중되는 네트웍 문제를 해결하고, 고객과 고객 또는 고객과 제공자들이 직접 거래를 할 수 있다. 본 논문에서는 현재 진행되고 있는 P2P 비즈니스 모델의 고찰과 P2P 기반 에이전트 시스템에 대하여 연구하였다.

The "information roadway" will give us an impact of new PC based assignments and administrations, yet the unusualness of this new condition will ask for another style of human-PC association, where the PC transforms into a sharp, dynamic and customized partner. Interface administrators are PC programs that use Artificial Intelligence frameworks to give dynamic help to a customer with PC based errands. Operators drastically change the present client encounter, through the similitude that a specialist can go about as an individual collaborator. The operator procures its capability by gaining from the client and from specialists helping different clients. A couple of model administrators have been gathered using this methodology, including authorities that give customized help with meeting planning, electronic mail taking care of, Smart Personal Assistant and choice of diversion. Operators help clients in a scope of various ways: they perform assignments for the client's sake; they can prepare or educate the client, they enable diverse clients to work together and they screen occasions and methods.

본 논문에서는 대표적인 3차원 일인칭 액션 게임인 Unreal Tournament 게임과 이것에 기초한 지능형 에이전트 연구용 테스트베드인 Gamebots 시스템을 소개한다. 그리고 이들이 제공하는 3차원 가상환경에서 동작하는 지능형 NPC인 KGBot의 설계와 구현에 대해 설명한다. KGBot는 Gamebots 시스템 내의 하나의 보트 클라이언트이다. KGBot는 3차원 가상환경 안에 숨겨진 목표점들을 찾아 효과적으로 점령하는 임무를 수행한다. KGBot는 범용의 BDI 에이전트 구조인 UM-PRS를 제어엔진으로 채용하고 있으며, 복잡한 행위들을 여러 계층으로 표현한 계층화된 지식베이스를 가지고 있다. 본 논문에서는 미지의 월드를 효과적으로 탐색함으로써 숨겨진 목표점들의 위치를 빨리 파악하고, 흩어져 있는 이동점들과 경로들을 찾아내어 경로 그래프를 작성하며, 이것에 기초하여 특정 목적지까지 지적의 이동 경로를 계획하는 KGBot의 지능 행위들에 대해 자세히 설명한다. 그리고 끝으로 다양한 3차원 지도를 이용한 실험을 통해 KGBot의 월드 탐색 전략과 제어엔진의 성능을 분석해본다.
