An intelligent robot should decide its behavior accordingly to the dynamic changes in the environment and user's requirements by evaluating options to choose the best one for the current situation. Many intelligent robot systems that use the Procedural Reasoning System (PRS) accomplishes such task management functions by defining the priority functions in the task model and evaluating the priority functions of the applicable tasks in the current situation. The priority functions, however, are defined locally inside of the plan, which exhibits limitation for the tasks for multi-domain services because global contexts for overall prioritization are hard to be expressed in the local priority functions. Furthermore, since the prioritization functions are not defined as an explicit module, reuse or extension of the them for general context is limited. In order to remove such limitations, we propose a policy-based meta-planning for general task management for multi-domain services, which provides the ability to explicitly define the utility of a task in the meta-planning process and thus the ability to evaluate task priorities for general context combining the modular priority functions. The ontological specification of the model also enhances the scalability of the policy model. In the experiments, adaptive behavior of a robot according to the policy model are confirmed by observing the appropriate tasks are selected in dynamic service environments.

In recent years, our society, because of the arrival of a new paradigm according to the rapid changes in ICT has entered into future smart society and the ubiquitous era. So it can be a notable turning point in the city and administrative spatial informatization, aspects of the era change. Therefore, this study was to derive a desirable vision for the city of Busan Centum City Informatization in the dream of leading global smart city of Busan by applying 'scenario planning' as a foresight method. Soon this study derived a successful local informatization strategy for Centum City in Busan. It proposed the use of the administrative aspects of information with spatial informatization as metadata information. Also this study explored the future leadership strategy of Busan Centum City in smart society. Eventually in 2030 to around, In order to still remain Busan Centum City as a leading ICT smart city, this study suggested the following strategy. It is important to increase the satisfaction of citizen services through the use of the administrative aspects of information with spatial informatization as metadata information for urban information system.
