In this paper, we describe the design and implementation of the FDRA(Fault Detection Recovery based on Agent) running on distributed multimedia environment. DOORAE is a good example for distributed multimedia and multimedia distance education system among students and teachers during lecture. It has primitive service agents. Service functions are implemented with objected oriented concept. FDRA is a multi-agent system. It has been environment, intelligent agents interact with each other, either collaboratively or non-collaboratively, to achieve their goals. The main idea is to detect an error by using polling method. This system detects an error by polling periodically the process with relation to session. And, it is to classify the type of error s automatically by using learning rules. The merit of this system is to use the same method to recovery it as it creates a session. FDRA is a system that is able to detect an error, to classify an error type, and to recover automatically a software error based on distributed multimedia environment.

Multimedia services in the cloud have become a popular trend in the big data environment. However, how to efficiently schedule a large number of multimedia services in the cloud is still an open and challengeable problem. Current cloud-based scheduling algorithms exist the following problems: 1) the content of the multimedia is ignored, and 2) the cloud platform is a known parameter, which makes current solutions are difficult to utilize practically. To resolve the above issues completely, in this work, we propose a novel distributed multimedia scheduling to satisfy the objectives: 1) Develop a general cloud-based multimedia scheduling model which is able to apply to different multimedia applications and service platforms; 2) Design a distributed scheduling algorithm in which each user makes a decision based on its local information without knowing the others' information; 3) The computational complexity of the proposed scheduling algorithm is low and it is asymptotically optimal in any case. Numerous simulations have demonstrated that the proposed scheduling can work well in all the cloud service environments.

This paper explains design and implementation of Multimedia E-mail system as a research on multimedia service. It is based on MIME(Multipurpose Internet Mail Extensions) which extends RFC822. MIME is a standard mail tran sfer protocol which can include multiple objects in a single message, represent non-textual material such as images and audio, exchange without loss of multimedia information through SMTP(Simple Mail Transfer Protocol). It is implementation of Multimedia Mail system which can store, delete, edit and tran sfer multimedia mail misgave in user friendly way on UNIX system. It aims tp develope framework for multimedia E-mail system.

The multimedia data of game affects the immersion of the game depending on its quality. It is difficult to design the evaluation criteria of artistic quality of the data. But, in a technical point of view, it is possible to evaluate its quality. Thus, the design of evaluation standard can ensure the reliability and objectivity of quality. However, multimedia data quality evaluation metrics had not yet been designed. Therefore, in this study, we extracted quality evaluation elements of Game Multimedia Data, and verified the reliability of the elements. And we defined detailed evaluation items of each element, developed Multimedia Data Quality Evaluation Metrics. We expect that the results of this study will serve as a guide in the development of high-quality games, have a positive impact on the growth of the game industry.

Recently, a demand of adaptive multimedia service, which supports multimedia service migration according to user's location and characteristics of user device, is increased. In this paper, we propose a service migration system, which becomes aware of user device using intelligent agent. And we design and implement the ontology-based intelligent agent, which is aware of the context in its environment. Moreover, we implement a context reasoning system using location information.

As wireless internet market grows rapidly, demands of various contents in wireless internet is significantly being increased. The contents that customers are taking advantage of have changed from single media content to multimedia content. As the technology of cellular telephone and broadband grows, the development of multimedia contents that can future represent characteristic of user will be more increased. One example of such content developments is ring-tone content service. Ring tone content service changed from existing simple ring tone to various sound services that depend on characteristic of user. In this paper, we design and implement the multimedia greeting assistant system that firsthand produces multimedia greeting contents using various multimedia contents and provides multimedia greeting service to represent characteristic of user through elevating ring tone content service.

The multimedia system using computing environment should support the fast access speed on the large scaled high quality data in the functional side. And it can support interaction and adaptiveness on system users. But it is hard to support it all effectively in the existing multimedia systems. In this paper, we design the multi-tier hybrid multimedia system. The proposed system is based on the characteristics of a multimedia medium, and it has the merits of the CD-ROM based method and the web based method. On the experiments, we verified the efficiency of the proposed system.

This study was conducted to develop web-based distance learning program of basic nursing physical science which was composed of a multimedia contents such as documents, voices and pictures. This was to advance curriculum of basic nursing physical science based on a proper nursing characteristics related to other major nursing subjects and induce a new and creative method to gain a knowledge. Based on a general learning design model, distance learning program was developed centered on a structure and function of heart physical science in 1999. The stages of development were like this. Firstly, at the analytic stage, specific units and contents for developing multimedia contents were decided and presentation methods for each item were designed and then the evaluation items were developed. Secondly, at the design stage, the most effective design of multimedia construction was selected and interfaces, basic frames, and presentation elements were chosen. Thirdly, at the developmental stage, internet files were designed using Namo web editor 4.0 and this files were modified with Adobe Photoshop.
