Context-aware multiagent system: Planning home care tasks
Get PDFContext-aware systems are able to capture information from the context in which they are executed, assign a meaning to the gathered information, and change their behavior accordingly. As a result, the systems can offer services to users according to their individual situation within the context. This article analyzes the important aspects of context-aware computing such as capturing information for context attributes and determining the manner of interacting with users in the environment. Used in conjunction with mobile devices, context-aware systems are specifically used to improve the usability of applications and services. This article proposes the home care context-aware computing (HoCCAC) multiagent system that identifies and maintains a permanent fix on the location of patients in their home, and manages the infrastructure of services within their environment securely and reliably by processing and reasoning the data received. Based on the multiagent system, a prototype was developed to monitor patients in their home. The HoCCAC multiagent system uses a critical path method-based planning model that, in the present study, prepares the most optimal task-planning schedule for the patients in their home, is capable of reacting automatically when faced with dangerous or emergency situations, replanning any plans in progress and sending alert messages to the system. The results obtained with this prototype are presented in this article
Laboratory procedures used for the third National Health and Nutrition Examination Survey (NHANES III), 1988-1994
Get PDFThis manual was designed to document the full scope of the laboratory component of the third National Health and Nutrition Examination Survey (NHANES III), which was conducted by the Division of Health Examination Statistics (DHES), National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC), from 1988 to 1994. It is a complete, working laboratory manual for nutritional biochemistry, immunology, hematology, and toxicology analyses as they were performed for this multi year national survey. NHANES III, which gathered data on 30,000 survey participants (or "SPs") in 89 different geographic locations across the United States, was divided into two phases, each of which provided nationally representative subset distributions of the U.S. population: Phase I (1988-1991) and Phase II (1992-1994). A complete description of the survey, including all questionnaires used and descriptions of all survey procedures may be found in the Plan and Operation of the Third National Health and Nutrition Examination Survey 1988-1994 (National Center for Health Statistics.
