With a rapid growing of information networks and development achievements in mobile technology the spatial information is one of the most important resources for modern daily life. But the speed of spatial information technology trends are far from the real service demands as compared to the other relevant fields, and it would be natural that this unbalanced gap between the supply and demand of spatial information technology is being resulted from the absence of appropriate modeling concepts at some extents. In this paper there would be shown a new approaching model for the spatial information system based on agent concepts, which is able to perform some spatial tasks if properly implemented afterward. And to give resonable background of the new modeling framework here also some known critics for the commonly used modeling approaches when they applied to spatial information modeling followed by several alternative requirements for a good spatial modeling framework. And also there would be some considerations for applying this approach to the marine geographic information communities.

멀티 에이전트 시스템은 공통의 목표를 위해 함께 일하기로 합의한 협업 에이전트로 구성된다. 에이전트 시스템에서 메시지를 스케줄링 할 때, 동일한 우선순위가 역할의 중요도를 고려하지 않고 모든 에이전트에게 동일하게 할당된다면 성능은 극대화되지 않을 것이다. 본 논문에서 우리는 새로운 메시지 기반 우선순위 스케줄링 기법을 제안한다. 그것은 에이전트 시스템으로 하여금 에이전트와 메시지 작업 처리량의 중요도에 기반으로 메시지의 우선순위를 적절하게 모델링함으로써 환경 변화에 신속히 적응할 수 있게 한다. 에이전트 시스템의 성능은 저자들에 의해 개발된 에이전트 플랫폼을 통해 실행된 범죄 예방 시스템에 대한 사례 연구를 이용한 제안된 계획에 의해 상당히 개선된 것으로 보여준다.

This paper explores a border security system based on agent-based modeling and simulation (ABMS). The ABMS software platform, map aware non-uniform automata, is used to model various scenarios and evaluate the border security system given a set of infiltrators who have evolutionary behavior governed by genetic algorithm (GA). we formulated an optimization model and approximately solved it using a GA in order to capture near optimal behavior of an infiltrating force. The results presented give two significant insights for our border security system in that optimizing the infiltrator's behavior can make a significant difference and the quantitative results regarding the infiltrator's avoidance of each asset can be viewed as capturing their relative importance.

Context-awareness is one of the key features of ubiquitous paradigm. A methodology that is specifying the relationships between the contexts and services needs to be developed to intelligently and sensitively deal with dynamic environment. The existing models on context-aware modeling are difficult to verify the correctness of models with respect to timeliness. In this paper we propose an approach which includes timing constraint in the relations of the context model, and verify its effectiveness using colored Petri-Net. Moreover, a context-modeling toolkit including context-awareness engine and simulator is developed to support agent-based context-aware service. The effectiveness of the proposed methodology is demonstrated using an example of Usilvercare.

In this paper, we design and implement an agent-based mask dance guidance system which provides multimedia information on traditional masques through WWW. When the server receives a query from the client, it produces the multimedia data by connecting several real full-motion videos, and synthesizing adequate voice data for guiding announcement. To develop an agent-based guidance system, we designed and implemented four agents such as interface agent, user modeling agent coordinator agent and data management agent. The mask dance guidance system also provides the functions of searching using the keyword and learning.

실시간으로 급변하는 전장상황에서는 군수물자의 보급이 절대적으로 중요하다. 최근에는 군수 물자를 사람이 아닌 다수의 에이전트를 이용하여 물류 수송을 관리하려는 다양한 시도가 이뤄지고 있다. 지능형에이전트를 이용한 추론 및 의사결정을 위한 시뮬레이션 모델링에 대해선 많은 연구가 이뤄져 왔으나, 전장에서의 특수성을 고려한 모델이 아니므로 그대로 적용하기에는 다소 무리가 있다. 본 논문에서는 이러한 문제를 해결하기 위해 전장상황에 특화된 BDI를 통해 다중 에이전트 환경에서 적용 가능한 군수 물자 수송 모델링 방법에 대해 알아본다.

Many researchers have modeled complicated problems with distributed AI technologies in distributed environment. Especially, intelligent agent technology we often proposed among researchers as efficient method to solve the complicated problems because agent technology makes possibile to share different problem solving abilities among processors in distributed processing environment. In this paper, we propose multiagent system model to solve distributed scheduling problem. At this point we apple CSP techniques to the multiagent model as individual problem solving ability of member agents. Scheduling problem is divided into subproblems according to constraints by distributed resources, then each agent solves its subproblem using CSP solver in the proposed model. This method improves scheduling efficiency. For meeting scheduling problem of case study, we show CSP modeling process and suggest problem solving procedure by multiagent system model.

The purpose of this research is to develope and implement a convergent educational contents based on theoretical background of integrated education using agent based modeling in the ubiquitous learning environment. The structure of this contents consists of three modules that were designed by trans-disciplinary concept and situated learning theory. These three modules are: convergent problem presenting module, resource of knowledge module and learning of agent based modeling and IT tools module. After the satisfaction survey of the implemented content, out of 5 total value, the average value was 3.86 for effectiveness, 4.13 for convenience and 3.86 for design. The result of the survey shows that the users are generally satisfied. By using this u-learning contents, learners can experience and learn how to solve the convergent problem by utilizing IT tools without any limitation of device, time and space. At the same time, the proposal of structural design of contents can be a good guideline to the researchers to develop the convergent educational contents in the future.
