Medical staff in the Intensive Care Unit (ICU) are confronted with large volumes of continuous data from several physiological sources which require interpretation. The ASSOCIATE system analyses historical data for summarisation and patient state assessment. It uses a temporal expert system based on associational reasoning and applies three consecutive processes: filtering, which is used to remove noise; interval identification to generate temporal intervals from the filtered data -intervals which are characterised by a common direction of change (i.e increasing, decreasing or steady); and interpretation which performs summarisation and patient state-assessments. Using the temporal intervals, interpretation involves differentiating between events which are clinically insignificant and events which are clinically significant and determining the outcome of therapy. Inherent in this process is the trend template which is used to represent events. Trend templates support temporal reasoning, knowledge to differentiate between events and taxonomical knowledge. Algorithms which are analogous to the way clinicians identify events use these trend templates.
In Nigeria, as more secondary schools and tertiary institutions contemplate developing educational materials and programs for delivery via the internet in order to complement traditional classroom teaching, there is the need to assess the effectiveness of the internet as a medium for delivering educational packages. This paper describes an exploratory study that investigated the possibility of integrating e-learning with traditional methods of teaching at an American styled university in Nigeria. By discussing possible reasons for the performance and disposition of sampled students towards e-learning, we suggest implications and effects of internet-based education on student learning.
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.
