This paper introduces a Web-based tool that has been developed to facilitate learning object annotation in agricultural learning repositories with IEEE LOM-compliant metadata. More specifically, it presents how an application profile of the IEEE LOM standard has been developed for the description of learning objects on organic agriculture and agroecology. Then, it describes the design and prototype development of the *** repository tool: a Web-based for annotating learning objects on organic agriculture and agroecology, organizing them in using a portfolio-like user interface in a learning repository, and then federating this repository with a network of agricultural learning repositories.

The research and development (R&D) investment timing decision-making problem is studied based on option game theory in this paper. The existence and inequality of two businesses operating costs are assumed, and jump diffusion is used to describe sudden events. The duopoly option game model is established to obtain the R&D investment value function and the critical value to invest. The game strategy and profit matrix of both firms are constructed, to discuss the existing forms of equilibrium, so that each timing for sequential equilibrium, preemptive equilibrium and simultaneous equilibrium is achieved.

PHP is one of the leading web development languages, however,the development model of existing PHP organizes without a structure, which mixes the code of data access, the processing of business logic,and web presentation layer together, as a relult, it brough about many problems in the web applications, meanwhile, it could not meet the rapid development of web apply any more. In this paper, a implementation of PHP based on MVC design patterns - FDF framework was provided for PHP developers, which can offer a framework for web applications, separate the data, view and control of web applications, afford to achieve loose coupling, thereby enhanced the efficiency, reliability, maintainability and scalability of application development.

E-Learning is widely used to facilitate and enhance learning in higher education. For developing any e-Learning program, direct and indirect costs associated with digital learning content should be measured. Normally, over 60% of total e-Learning costs are spent on design, development, publication and evaluation of learning content. However, the rapid growth of high quality digital content has become a challenge to tertiary education institutions. This paper discusses the employment of new technology known as learning objects for creating cost effective learning content. By investigating essential factors that affect learning content development, variables influencing the development cost are identified. Identified variables associated with content development process are prioritized based on the extent and significance of each variable in the context of 'cost'. Through taking control of these seemingly controllable variables, the content development cost can be minimized and thus cost effective learning content can be created.
