This paper presents an ongoing project on the development of an e-Engineering framework proposed by KIMM (Korea Institute of Machinery and Materials). The framework is based on a number of advanced technologies, such as intelligent software agents, Web Services, and Service-Oriented Architecture. And it aims to provide an integrated design environment to support integrating personnel, design activities and engineering resources during product development process. Especially Service-Oriented Architecture technologies enable to utilize and integrate effectively various engineering resources on the heterogeneous geographically distributed computing environments.

PDA devices have become an accessory that a large community uses for managing their personal data. With the development of new devices with additional network and video capabilities they gain the potential to be used in more comprehensive communication scenarios too. On the example of usage for image communication we show, how new applications must not be viewed in an isolated way and need innovative approaches for both system hard-and software enhancement as well as for the integration with heterogeneous infrastructure components. The challenging task for creating so called communication appliances is not just to transfer existing desktop mechanisms to smaller and mobile computers but to consider their specifics and establish additional architectures and mechanisms that meet those best. Our paper describes the prototyping of image communication device based on an off-the-shelf PDA, design and usage experiences and potential future enhancements.

XML documents are increasingly being used to mark up various kinds of data from web content to scientific data. Often these documents need to be collaboratively created and edited by a group of users. In this paper we present a flexible solution for supporting collaboration over XML documents. Merging of user work is based on the operations performed. A key to achieving flexibility for the definition and resolution of conflicts was to keep the operations distributed throughout the tree model of the document associated with the nodes to which they refer.

This paper discusses a prototype desktop ambient display system known as the Ambient Workplace (AW) that is used to visualise some aspects of cooperation among a group of co-workers. The AW draws on the ambient technology paradigm by providing a visualisation that represents the interactions of the co-workers (either individuals or groups) in their peripheral attention zone. The paper discusses the development of a prototype system based on a series of indices and uses a maritime flags metaphor. The paper also presents some early results from a user study.

The integration of knowledge-based, devices-based and decision support systems have a very promising future in scientific research. The authors of this paper participated in the project Framework 6, ‘Bringing Retrofit Innovation to the Application of Public Buildings’ (BRITA in PuBs). One of the project’s goals was to develop a Building’s Refurbishment Knowledge and Device Based Decision Support System (BR-KDDSS), which consists of a Decision Support Subsystem, Knowledge Subsystem and Device Subsystem. In order to demonstrate the integration of knowledge, device and decision support systems, the BR-KDDSS will be considered as an example.

The paper aims to analyse the construction contracts provided by FIDIC (International Federation of Consulting Engineers) and to determine their usefulness in respect of technical risk management. Contractors of international construction projects are often faced with complicated situations working with design documentation. One of the potential financial risk factor is associated with the frequent changes of documents and improper channels of communication between project partners. One of the major aspects is project financial and technical risk management. Project developers need various models of managing large and complex projects.

This paper aims at finding an efficient way for discovering which specific knowledge each student does not possess in order to successfully start a new course or to proceed with another section in a current subject. Most existing tutoring systems respond to students’ mistakes by providing links to a collection of teaching materials. Such an approach does the individual needs of each student. Our idea is to apply a holistic approach that involves looking at the whole system of each student knowledge within an subject rather than just concentrating on single mistakes, lack of knowledge or misconception.

The standardization of eLearning environments is causing a constant evolution of the standards, the specifications, the reference models and the best practices of these specifications. Mainly, this evolution is a consequence of the educational and computational paradigms which the standardization applies and of the pedagogic and cognitive requirements of the learner using these environments. or (LD) is an approach on specifications in the standardization process centred on cognitive characteristics and on the learning process itself. In this case, the learning process is isolated from the learning object design. This is, LD is centred on , not in . IMS Learning Design (IMS-LD) is the specification used to describe the learning design. We are working in the AULA_IE project whose objective is to evaluate different standards and to check their application and contribution in Computer Supported Collaborative Learning (CSCL) environments. As a consequence of this evaluation we have observed a lack of semantics when some activities and tasks are specified. Based on this result, we propose a reference model inside the IMS specifications core.

The development of mechatronic products requires the integration of different technical disciplines by personnel who reside in separate locations, a fact that is particularly evident for the case of virtual enterprises. Concurrent engineering of these products can be enhanced significantly through the use of sophisticated data management and visualization tools such as Product Lifecycle Management (PLM). The key benefit of a PLM system is its ability to facilitate the coordination of the activities among geographically distributed team members. This paper describes models and procedures that were developed and implemented during the selection and configuration of a PLM environment for machine tool design and construction in a virtual enterprise. The experiences from this case, particularly the bottlenecks and how they were addressed are discussed in detail. Finally, recommendations for better deployment of PLM for similar conditions are presented.

The construction industry has continuously tries to improve the productivity of construction projects through Information Technologies (IT). It is not easy for the subcontractor to apply IT towards their projects due to the smaller scale of operations and the problem of the cost of equipment, programmer, and operator to introduce IT. To overcome the high investment risk we need a device. This paper presents IT outsourcing for subcontractors that effectively accommodates the demand of project information management. The purpose is the conceptual design of an Application Service Provider (ASP) based project management system. This paper offers the conceptual proposal for the mutual communication and information collection between the construction industry subjects through collaboration and the coordination.
