Effective manipulation of context is very important in providing the context-aware services. In recent years, a variety of context models have been proposed to properly handle the key aspects of the context, while focusing on scenario-based acquisition, management, and representation of context. However, they are difficult to be employed for the agent-based system requiring distributed reasoning. In this paper we propose a context modeling approach for distributed reasoning and merge operator reflecting the perspective of constituent agents for rational reasoning. In addition, an agent-based context-aware system is developed implementing the proposed scheme. Performance evaluation by computer simulation on a use case of smart classroom shows that the proposed approach enables the agents to rationally reason and thereby provide intelligent context-aware services to the users.

In the hospital settings, falls occur for a wide scope of reasons but most of the time they could be prevented. Therefore, clinical supervision as a strategy to improve and develop nurses’ knowledge and skills is crucial for a better clinical practice. The aims of this quantitative, exploratory and descriptive study were: to characterize the risk of falling of hospitalized patients in a unit of the medicine department;to relate the risk of falling with the patients’ personal attributes;to analyze the compliance between the procedures for monitoring, planning and execution of nursing care;to suggest contributions for a clinical supervision model in nursing to improve nurses’ skills in preventing falls. The population was composed by all the patients of the selected unit who were hospitalized from the 10 th of February 2012 until the 9th of April 2012. We had a convenience sample constituted by 132 patients who fitted the inclusion criteria. We collected data through several procedures such as the application of a questionnaire to assess the risk of fall accordingly to the falls protocol implemented in the unit and the parameterization defined in the nursing records system. The results pointed out that 16,7% of patients showed "no risk of fall", 48,5% had "low risk of fall" and 34,8% had "high risk of fall". We verify the existence of non-conformities in the implementation of the falls protocol, the application of the Morse Fall Scale, among others. Thus, we recommend some contributions for a clinical supervision model in nursing so nurses can develop their knowledge and skills in preventing patients’ falls.

the paper presents an integrated information system for monitoring current state of natural resources and providing valuable help by assisting decisions makers in critical situations. The specific case studied is from the domain of water resources management but the architecture is easily adaptable to suit other types of natural resources (e.g. soil, air). The key points of the proposed solutions are standardization, web services and cloud computing.
