The prior data structure coursewares have been limited to using a simple screen structure with text, pictures or plain animation so that they have been failed to promote favorable interaction between learners and instructors, and unnecessarily charges the screen. In order to overcome these problems, this paper provides an applet-based simulation environment which enables learner to operate and control the data structure operation with their own data, therefore, the learners can actively and positively participate in a study with this courseware. The instructors can easily deliver the education contents to the learners by using web simulation suitable for IT education media. Also, the courseware can offer a class feedback and required data for students estimation by recording a log.

정보기술 기반의 사회를 맞이하는 시점에서 멀티미디어를 기반으로하는 정보화 사회(Information Society)와 지식기반 사회(Knowledge-based Society)는 현재와 미래를 규정하는 거시적 패러다임으로 인식되고 있다. 정보 기술 사회(Information Technology Society)로 정착해 가는 시점에 처해 있는 우리 사회는 농경 사회와 산업 사회의 논리로는 도저히 해석되지 않은 각종의 시스템 시뮬레이션 모델들이 끊임없이 제시되고 있으며, 그것이 실제로 실현되는 가히 혁명적인 상황 속에 놓여 있다.(중략)

Web-based MMORTS has features that distinguish it from traditional client-based games. First, Web-based MMORTS is represented by the combination of graphics and texts. Second, there is parallax agent which has a player and a base town character. This paper written for the purpose of analyzing the storytelling of web-based MMORTS, and from Innogames selected as the subjects of the study. In view of the results so far achieved, the fact, when the player logs in web-based MMORTS, the player takes the experience after some time which had taken by the AI character instead of the player logged out and User Generated Storytelling created from this process, become known. This paper has a meaning for Web-based virtual world which can juxtaposition with routine tasks and can be linked with other platforms.

Web based simulation service is actively utilized to computably analyze various kinds of phenomena in real world according to progress of computing technology and spread of Network. However it is hard to share data and information among users on the services, because most of web based simulation services do not share and open simulation processing information and results. In this paper, we design a simulation provenance data sharing service on EDISON_CFD (EDucation-research Integration Simulation On the Net for Computational Fluid Dynamics) to share the calculated simulation performance information. To store and share the simulation processing information, we define the simulation processing step as "Problem ${\rightarrow}$ Plan, Design ${\rightarrow}$ Mesh ${\rightarrow}$ Simulation performance ${\rightarrow}$ Result ${\rightarrow}$ Report." Users can understand a problem solving method through a computer simulation by searching the simulation performance information with Search/Share API of the store. Besides, this opened simulation information can reduce the waste of calculation resource to process same simulation jobs.

In this paper, we introduce a web-based scheduling toolkit(GridTool2), which can run simulation of scheduling algorithm in grid system. And we suggest new algorithms which apply additional communication costs to the existing MinMin and Suffrage scheduling algorithms. Since GridTool2 runs in web environment using server and database, it does not require a separate compiler or runtime environment. The GridTool2 allows variables such as communication costs on the web for performance evaluation, and shows simulation results on the web page. The new algorithm with communication costs was tested using GridTool2 to check for performance improvements. The results revealed that the new algorithm showed better performance as more workloads were incorporated to the system.

Service-Oriented Architecture(SOA) define the interaction method between two computing entities that one entity performs a unit task instead of another entity. This, unit task, is called "Service" and interaction of these services should have independency and loosely coupled task. The effect of SOA's main functions such as loosely coupled task and independent interoperability with influence the possibility of flexible message communication between different way and different users. In this article, we analyzed the performance about system stabilization between general web service and SOA based application that implemented through WCF based messaging framework using .NET Framework and integrated data presentation method. As the result of test, we confirmed that SOA environment using WCF have more advantages.

This paper proposes the ship-handling simulator framework using web technology to solve the complexity and non-scalability problems of a common simulator system. We analyze the essential functions of the existing simulator system, and selects web technologies to replace them. Based on this framework, we implemented core technologies for server and client system, and integrated a prototype of a ship-handling simulator system that can be accessed from a web browser. The prototype has verified that the simulation service can be used by multiple users at the same time without being restricted by time and place through the evaluation test, and it is hoped that it can be applied to various simulation fields in the future.

민첩생산의 필요성이 날로 증가하고 있는 생산환경 하에서 대표적인 자동생산시스템인 FMS의 효율적인 운영과 동시에 원격지에서의 FMS 모니터링 및 제어는 필수화되고 있다. 최근에 시뮬레이션을 기반으로 하는 가상생산의 개념이 일반화되고 이를 지원하는 다양한 정보기술의 발전에 따라 FMS에도 적용되고 있다. 본 논문에서는 웹환경 하에서 실재 FMS와 이에 대응되는 가상 FMS를 통합함으로서 원격지에서의 효율적 운영을 지원하는 모니터링 및 제어시스템 구축방법을 소개하고자 한다. 또한 키트형 FMS와 이에 대한 가상 FMS 모델를 대상하여 적용한 결과를 소개하도록 한다.
