The design of Japanese houses and their rooms is very important. However, this is now easy because people have different feelings. In order to deal with this problem, we have developed a digital traditional Japanese crafting system (DTJCS) which provides a presentation space for traditional Japanese crafting. In this paper, we analyze the effect of room change of fittings to people's feelings using the presentation system.","PeriodicalId":217602,"journal":{"name":"14th International Workshop on Database and Expert Systems Applications, 2003.

Exposing Virtual Terminal functionalities as XML Web services will have a number of advantages compared to the current version of the Virtual Terminal. First of all it will enhance the accessibility of the service, enabling 3rd parties to introduce it to new market segments in a straightforward way. Customization of the service will be possible enabling different flavours of Virtual Terminals to be introduced, and finally, the virtual Terminal functionalities will be available to other applications and not only human end users. In this way, the Virtual Terminal functionalities can be invoked by applications and utilized as components in order to build a wide range of other complex services.","PeriodicalId":217602,"journal":{"name":"14th International Workshop on Database and Expert Systems Applications, 2003.

In the CIPHER project we aim to provide customisable tools for the sharing of stories in communities, and test these tools in specific case studies. Here we describe the generic storytelling environment customised for two quite different communities, a group of adult volunteers interested in a particular heritage area and children collaborating from two different schools. The participatory development of the tools has highlighted a number of design recommendations for the development of community story sharing support including story seeding, role identification, launch strategy, and the model of communication and story exchange.","PeriodicalId":217602,"journal":{"name":"14th International Workshop on Database and Expert Systems Applications, 2003.

Since copying of coins cannot be prevented cryptographically in anonymous off-line coin systems, double-spending detection is one of the major tasks. An observer is a tamper resistant device that prevents double-spending physically. While privacy protection is a desirable property of cash systems, perfect anonymity is not. Perfect anonymity enables criminals to do perfect blackmailing or money laundry according to B. von Solms and D. Naccache (1992). To prevent a perfect crime it has to be possible to revoke the anonymity of customers in case of need. Anonymity revocation is done by a trusted third party. Cash systems that allow anonymity revocation are called fair. We present a coin system which features both observer and fairness. This shows that both concepts do not interfere and can be implemented simultaneously without loss of security.","PeriodicalId":217602,"journal":{"name":"14th International Workshop on Database and Expert Systems Applications, 2003.

It is nearly impossible to foresee, at business process design stage, all the combinations of tasks needed to achieve the process' goals. Workflow management systems capable of supporting dynamic changes on executing instances in a flexible manner are thereby demanded. Former approaches have proposed a solution to this issue based on workflow type versioning and workflow instance migration. However, the operations that handle the modification of workflow types as well as the migration algorithm for workflow instances are tied to a particular representation of workflow types. This means that whenever the representation changes, the migration algorithms and the modification operations have to change accordingly. This is a current problem due to the uprising of different specifications for workflow definition languages, which are far away from stabilizing. In this paper, we address this problem by clearly decoupling the modification operations of workflow types from the internal structures and algorithms responsible for the instances' migration. In this manner we enable the use of different workflow definition languages while keeping the same internal structures and migration algorithms.","PeriodicalId":217602,"journal":{"name":"14th International Workshop on Database and Expert Systems Applications, 2003.

Ideally, these networks enable the participating devices to share resources and services, thus overcoming the often severe limitations of the individual devices' capabilities. In order to make this possible, powerful semantic service trading is needed. In this paper, we propose a semantic overlay of hierarchical service rings to achieve this goal. In contrast to existing approaches this method is adapted to the specific characteristics of ad hoc networks.","PeriodicalId":217602,"journal":{"name":"14th International Workshop on Database and Expert Systems Applications, 2003.
