This study used a conceptual framework to examine how advanced information systems should be developed and used to improve the health and quality of life of Americans. In this study the problem was defined as the poor lifestyle choices and health habits of Americans. The research problem was defined in terms of how to develop and use a conceptual framework for the design of a system that is based on the best theoretical science, that features the right mix of technologies, and that is sufficiently sophisticated and comprehensive to be able to address the health problem in a highly effective manner. The goal of this study was to produce a design for a model informatic system that could be used as a blue print for the multidisciplinary development teams and researchers who will be working on or evaluating the next generation of health promoting technologies.
A mixed-methodology design and the Systems Development Life Cycle (SDLC) model were used to develop the conceptual framework , design the model system, and, in the process, indicate how and why this particular framework and innovative design would be superior to the other products and systems that are on the market today. The recommended state-
The second part of this dissertation presents the results of an environmental quality survey utilizing the Environmental Protection Agency's TRI Explorer database as well as the United States Geological Survey water quality database could provide a valuable tool for the assessment of land, air, and water contamination. The top three air, water, and land releases will be obtained from 1988 to 2002 for counties surrounding major cities in Tennessee. There was found to be a poor correlation between the TRI Explorer and USGS data for the counties in this study. This poor correlation may be due to the degradation pathways of the chemicals released. It should be noted that there has been a decrease in many of the compounds, such as chlorofluorocarbons, which have been addressed in legislation.
Air samples were collected on mixed cellulose ester filters and silver membrane using a GS Cyclone particle size selector and analyzed using Scanning Electron Microscopy with Energy Dispersive X-ray Analysis. Unlike quartz filters, sample loss and change was minimal with the use of the mixed cellulose ester filters and silver membranes. Residential air samples collected on mixed cellulose ester filters have indicated the presence of aluminum, silicon, carbon, and oxygen. All particles are cylindrical in shape and are less than 10 μm in aerodynamic diameter. Samples collected in heavily automobile congested areas are spherical and carbonaceous with a high carbon to oxygen ration.
