Chronic respiratory diseases have been on the rise, especially due to COVID-19, extreme air pollution, and other external circumstances. Millions of people around the world suffer from progressive lung diseases and require supplemental oxygen therapy to maintain blood oxygen (SpO2) levels above 90% to prevent hypoxic episodes that can lead to further organ damage. Today, these chronic episodes are more prevalent in aging populations suffering from Chronic Obstructive Pulmonary Disorder (COPD). Existing SpO2 measurement equipment, designed to assist with treating COPD at home, are suboptimal as they cannot measure SpO2 levels continuously, meaning supplemental oxygen devices are unable to adjust oxygen flow rates to the patient’s needs. These discrepancies can result in hypoxic episodes of blood oxygen levels below 90%. Following this need, our team demonstrates preliminary results of the novel placement of a SpO2 sensor in the nasal septum to allow for comfortable and sustained SpO2 measurement. This will improve the experience of home-respiratory care with continuously obtained data from a novel location.
A policy simulative model with the main purpose of simulating the effects of alternative policy moves and obtaining an accurate read-cut of resulting urban-suburban conditions is the focus of this paper.The model deals with the movement of various population groups and the resulting effects on some very broad indicators of city-suburban life, rather than with particular topics like transportation, land use and the like. The level of abstraction is thus intermediate and is directed at providing practical policy suggestions for a particular city--Newark--for which the model is calibrated. The model, however, is general enough in nature so that it can be applied to other urban-suburban complexes and therefore the policy suggestions made on a fairly broad basis.The outputs of the model are graphically represented to show the results of alternative policies which then may be compared. As a side benefit the inputs to the model can also serve as a "social report" on the present status of an area.Policy questions to be answered by the model include: Should a city budget be directed somewhat differently? Should a city ask the state or federal government for funding and for how much? What may be expected from imposing a city sales tax, weighing the revenue benefit against costs of lost sales or citizens? And last, would the federal government not be better off by simply giving money to the poor directly instead of to cities?
Over the past thirty years, considerable time and effort have been expended and a great deal of money has been spent on the study of learning disabilities and learning problemstheir causes, effects, and possible remedies. For the purposes of this discussion, learning disabilities may be defined as perceptual handicaps, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia. A learning disabled child is not mentally retarded; hidher IQ range may compare favorably with that of hidher peers, while hidher performance level does not. In other LEARNING PROBLEMS,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
