There are lots of intelligent service robots in these days. People are unwilling to do routine works, dangerous works, and difficult works. But a robot can do these works instead of human. We introduce a intelligent service robot for unmanned store management. The robot can detect and recognize a person, deliver some goods, manage a store, and answer the telephone. We have developed the robot and tested the performance.

The main idea behind the Intelligent Networks(IN) concept is the separation of switching functionality from the service control, in order to meet various service requirements of subscribers and development of new services in time. In (N+1) type Intelligent Network with FEP-BEP framwork, each SCP-BEP system maintains its own subscibers' database respectively. In this case, DB updating operations at each SCP-BEP should be peformed concurrently such that DB updating method could affect the overall system performance. Moreover, it is not easy to predict the current system capacity to satisfy the future IN subscribers' service needs. In this paper, we discuss how much DB updating method affects the performance trends of (N+1) type Intelligent Network with FEP-BEP system by means of the simulation technique as the number of calls increase. The average turnaround time is used as a system performance measure.

Recently, a need of non-industrial robot, such as service, medical, entertainment and house-keeping robot, has been increased. Therefore, the capability of robot which can do intelligent behavior like interaction with men and its environment become more prominent than the capability of executing simple repetitive task. To implement an intelligent robot which provides intelligent behavior, an effective system architecture including perception, learning, reasoning and action part is necessary. Control architectures for intelligent robot can be divided into two different classes. One is deliberative type controller which is applicate to high level intelligence like environment ...

차량과 무선 액세스망과의 연동을 통한 새롭고 다양한 멀티미디어 서비스를 제공할 수 있는 차세대 텔레매틱스 기술이 새로운 유망산업으로 소개되고 있다. 초기의 텔레매틱스 기술은 단순히 차량내에서 전자제어장치간의 제어, 모니터링, 내비게이션 등이 주였지만, 최근에는 외부의 무선 액세스망과의 연결을 통하여 모바일 인터넷 서비스, 위치정보 서비스, 긴급구조 서비스, 멀티미디어 서비스 등을 제공하고 있다. 본 논문에서는 이러한 서비스의 활성화와 효율성을 제공하기 위하여 차량내 텔레매틱스 모바일 플랫폼 구조를 제안한다.

To be successful in increasingly competitive Internet marketplace, it is essential to capture customer loyalty. This paper deals with an intelligent agent approach to incorporate customer's sensibility into an one-to-one recommendation service in on-line shopping mall. In this paper the focus of interest is on-line recommendation service algorithm for development of Human Sensibility based web agent system. The recommendation agent system composed of seven services including specialized algorithm. The on-line recommendation service algorithm use human sensibility ergonomics and on-line preference matching technologies to tailor to the customer the suggestion of goods and the description of store catalog. Customizing the system's behavior requires the parallel execution of several tasks during the interaction (e.g., identifying the customer's emotional preference and dynamically generating the pages of the store catalog). Most of the present shopping malls go through the catalog of goods, but the future shopping malls will have the form of intelligent shopping malls by applying the on-line recommendation service algorithm.

In pure P2P environment, it is possible to provide service by using a little real-time information without using accumulated information. But in case of using only a little information that was locally collected, quality of recommendation service can be fallen-off. Therefore, it is necessary to study a method to improve qualify of recommendation service by using users' context information. But because a great volume of users' context information can be recognized in a moment, there can be a scalability problem and there are limitations in supporting differentiated services according to fields and items. In this paper, we solved the scalability problem by clustering context information per each service field and classifying it per each user, using SOM. In addition, we could recommend proper services for users by quantifying the context information of the users belonging to the similar classification to the service requester among classified data and then using collaborative filtering.

The main idea behind the Intelligent Networks (IN) concept is the separation of switching function from the service control, in order to meet various service requirements of subscribers and development of new services in time. The (N+l) architecture of the IN service system consists of front-end processors (FEP) and back-end processors (BEP), which is in service in a domestic telecommunication company, and balances the traffic load for services among the processors. Under this architecture, the IN service system can distribute the traffic load dynamically, and M services are easily launched and manipulated minimizing impacts on the existing services. This paper traces the performance of the (N＋1) structured system by means of the simulation approach, and shed a light on the result.

전화번호이동성이란 전화서비스 가입자가 전화망 사업자, 지역, 서비스의 종류를 변경하여도 종전에 사용하던 전화번호를 변경하지 않고 그대로 사용할 수 있는 것을 뜻한다. 사업자를 변경해도 전화번호가 바뀌지 않는 것을 사업자 이동성, 지역을 바꾸어도 전화번호가 바뀌지 않는 것을 지역 이동성, 서비스의 종류를 변경하여도 번호가 바뀌지 않는 것을 서비스 이동성 이라고 한다. 이와 같은 이동성을 지능망을 통하여 제공하기 위해서는 INAP(Intelligent Network Application Part)의 보완이 필수적인데, 본 논문에서는 국내에서 번호이동성을 제공하기 위하여 필요한 INAP의 변경사항에 대하여 논한다.

The MICE(Meeting, Incentive travel, Convention, and Exhibition) industry grows steadily. Especially, exhibition industry plays an important role as the effective sales and marketing tools. However, lots of studies have focused on the flow analysis of audience traffic, booth recommendation or formulaic interactions between audiences and contents in the exhibition hall. In this study, we proposed an intelligent Interactive system considering audience's response for providing personalized exhibition service. First, we extracted components of the system architecture through the previous studies. Second, we suggested the system architecture and scenarios for intelligent interactions between audiences and contents. We hope that the proposed system will strengthen the basis for implementing interactive system in the exhibition industry.
