摘要:
The virtual learning community is an important application pattern of E-Learning. It emphasizes the cooperation of the members in the community, the members would like to share their learning resources, to exchange their experience and complete the study task together. This instructional mode has already been proved as an effective way to improve the quality and efficiency of instruction. At the present time, the virtual learning communities are mostly designed using static access control policy by which the access permission rights are authorized by the super administrator, the super administrator assigns different rights to different roles, but the virtual and social characteristics of virtual learning community make information sharing and collaboration a complex problem, the community realizes its instructional goal only if the members in it believe that others will offer the knowledge they owned and believe the knowledge others offered is well-meaning and worthy. This paper tries to constitute an effective trust mechanism, which could promise favorable interaction and lasting knowledge sharing.

摘要:
In role-based access control (RBAC) permissions are associated with roles, and users are made members of appropriate roles thereby acquiring the roles' permissions. The principal motivation behind RBAC is to simplify administration. An appealing possibility is to use RBAC itself to manage RBAC, to further provide administrative convenience. In this paper we investigate one aspect of RBAC administration concerning assignment of users to roles. We define a role-based administrative model, called URA (User-Role Assignment), for this purpose and describe its implementation in the Oracle database management system. Although our model is quite different from that built into Oracle, we demonstrate how to use Oracle stored procedures to implement it.

摘要:
Research probes some strategies to integrate digital rights management into learning content management system. Firstly discussed the art state of DRM (Digital Rights Management)-enabled learning resources management. Secondly discussed the designing objectives of the system. Next, the framework and model of DRM-enabled learning content management system are designed. In addition, it investigated the enforcement model of the license for learning resources, and the enforcement strategies of the license, which includes three basic processes. By getting the license, integration of learning content and usage of control information and delivery of the encrypted content are viable. At last, the development of the system is introduced. Because the key is real-time dynamic exchange, the security of learning content mainly depends on the servers. It made the system more secure and flexible.

摘要:
The design, development and management of e-learning resources are the key factors for a successful e-learning system. There exist problems like low-level repeating development and low-level sharing of resources in this filed. This paper discusses the application of e-learning standards for these problems. The sharing model for e-learning resources is presented and learning mode is discussed. The research also gives the detailed design and the realization of an object-oriented learning resource management system based on Internet and Chinese E-learning Technology Standards (CELTS). This includes the design of the abstract resource class in the system, methods for examining and importing of resources, management of resources, retrieving and displaying of resources, etc. The core and extended description set of resources and its realization of XML binding technology are also presented in the paper. Problems related to the distribution of resources are discussed. The charging mode, algorithm, and method for user registration using MD5 for private information encryption are provided.

摘要:
IPTV based E-Learning is an attractive and promising service for the widespread of TV devices and potential consumers. Especially in rural area in China, it is more useful than traditional web-based learning application for the lack of computers. However, the transition from traditional web-based Learning system to IPTV-based learning is not trivial for the limited input and control capabilities of the devices such as the keyboard and mouse. It is a challenge task to design an IPTV oriented E-Learning system and deliver web-based learning resources to the new IPTV platform. In this paper we study the learning process on IPTV platform and present the design methodology of an interactive IPTV-based E-Learning system. Several critical issues have been investigated carefully. At first a service framework for IPTV based E-Learning service is introduced. The interoperability with other traditional web-based learning system is enabled by the introduction of several interfaces based on Web Services. Then new development methods of IPTV-Oriented learning resources are then proposed. In addition, conversion strategies for traditional web-based learning resources to IPTV platform are also discussed. Thirdly we proposed the design methodologies for the learning interactivity, which is the key feature of IPTV-based application comparing to traditional VOD ones. To evaluate the framework and the methodology that we have proposed, a prototype IPTV-based learning service is developed.

摘要:
Rapid development of E-Learning applications brings large requirements of Virtual Classroom learning resources. Especially in teachers lecture courseware. However, the high technical requirement of courseware developers and low reusability of learning resources heavily impede the process of E-learning. There is an urgent need for virtual classroom system to assist teachers to develop and transmit standard and reusable courseware. The paper presented a virtual classroom system based on SCORM specification (VCS). The system has two major features. One provides visual courseware conforming to SCORM (Sharable Content Object Reference Model) specification. It can be reused and shared by the computer all over the world. Another key feature is development of the real classroom. It provides the standard service for the online students.

摘要:
With the rapid increase of learning resources, the contradiction between learning content Intelligent Properties and its share and reuse becomes an outstanding event. In order to solve the problem, we probe into a way to integrate the DRM technologies and learning technology standards into the development of a learning content management system. We also design a novel online management system for broadcasting environments of virtual classroom or courseware on demand based on a Browser/Server framework, which carries out learning content management for reuse, share, interoperation and security. We place particular emphasis on the strategies of integration of digital rights management and flexible commercial model by license services into application, management, exchange and trade of web-based learning content and try to solve the problem between reuse and protection.
