Εφυές σύστημα τηλεκπαίδευσης στην ακτινοπροστασία

Παπαχρήστου, Νικόλαος 11 February 2008 (has links)
Ένα εκπαιδευτικό λογισμικό κατασκευάζεται, προκειμένου με τη χρήση του να εκπληρωθούν συγκεκριμένοι μαθησιακοί στόχοι. Μπορεί να χρησιμοποιηθεί ως συμπληρωματικό μέσο διδασκαλίας από τον εκπαιδευτή ή ως υποστηρικτικό μέσο αυτοδιδασκαλίας από τον εκπαιδευόμενο. Αποτελεί μέσο αξιολόγησης ή αυτοαξιολόγησης του εκπαιδευόμενου, χωρίς βέβαια αυτό να αποτελεί κύριο σκοπό για την κατασκευή του. Οι σύγχρονες τεχνολογίες εκπαιδευτικού λογισμικού, που βασίζονται στις τεχνολογίες δικτύων υπολογιστών και των συστημάτων υπερμέσων, προσφέρουν την δυνατότητα να εξηγούνται, με παραστατικό τρόπο και πολλαπλά μέσα παρουσίασης, τα γνωστικά αντικείμενα, να διευκολύνεται η επικοινωνία και η συνεργασία μεταξύ εκπαιδευόμενων και εκπαιδευτών, να καταργείται η αποκλειστική χρήση μιας πηγής μαθησιακού υλικού, η οποία πολλές φορές περιέχει ξεπερασμένες πληροφορίες και, ως συνεπακόλουθο όλων αυτών, να μπορεί να αναπτύσσεται η κριτική σκέψη του υποκειμένου στην εκπαίδευση. Στην εργασία αυτή παρουσιάζουμε την συμβολή ενός τέτοιου προηγμένου συστήματος στην δημιουργία ενός μαθήματος για την Ακτινοπροστασία στους χώρους Υγείας. Για το σκοπό αυτό χρησιμοποιήσαμε μια εκπαιδευτική πλατφόρμα ικανή να παρουσιάζει προσαρμοστικά το περιεχόμενο, να προτείνει μαθησιακές δραστηριότητες ανάλογα με τον εκπαιδευόμενο, να προσφέρει διαφορετικούς τρόπους επικοινωνίας και συνεργασίας ανάλογα με το επίπεδο και τη διάθεση του μαθητή. Περιγράφουμε τους λόγους για τους οποίους τέτοια συστήματα μπορούν να προσφέρουν στην Ιατρική εκπαίδευση, καθώς και το πόσο απαραίτητο είναι το μάθημα της ακτινοπροστασίας για τα επαγγέλματα Υγείας. Παραθέτουμε την λειτουργικότητα των εργαλείων, τα οποία έχουν στη διάθεση εκπαιδευτές και εκπαιδευόμενοι, και τέλος αναφέρουμε τις τροποποιήσεις που κάναμε προκειμένου το σύστημα να διαθέτει ένα προσαρμοστικό τρόπο αξιολόγησης. Δίνουμε τα αποτελέσματα μιας πρώιμης αξιολόγησης του συστήματος-μαθήματος, από φοιτητές της Νοσηλευτικής του Τεχνολογικού Ινστιτούτου της Πάτρας. Τέλος αναφέρουμε μια συνοπτική περιγραφή της αρχιτεκτονικής και του τρόπου υλοποίησης του συστήματος. Η παρούσα εργασία αποτελεί ένα πρότυπο τόσο του πώς μια εκπαιδευτική πλατφόρμα μπορεί να χρησιμοποιηθεί για εκπαίδευση στους χώρους Υγείας, όσο και του πώς μια προϋπάρχουσα τέτοια εκπαιδευτική πλατφόρμα μπορεί να βελτιωθεί χρησιμοποιώντας τεχνολογίες τεχνητής νοημοσύνης. / -

The Effects of an Expert System on Novice and Professional Decision Making with Application in Deception Detection

Jensen, Matthew Lynn January 2007 (has links)
One effective way for organizations to capture expert knowledge and experience is to encapsulate it within an expert system (ES) and make that system available to others. While ES users have access to the system's knowledge, they shoulder the difficult task of appropriately incorporating the ES recommendations into the decision-making process.One proposed application of an ES is in the realm of deception detection. Humans are inherently poor at recognizing deception when it occurs and their confidence in their judgments is poorly calibrated to their performance. An ES has the potential to significantly improve deception detection; however, joining an ES and a human decision maker creates many important questions that must be addressed before such a system will be useful in a field environment. These questions concern changes in decision outcomes, decision processes, and the decision maker that result from ES use.To examine these questions, a prototype system was created that implements new and unobtrusive methods of deception detection. Kinesic analysis examines the body movement of a potential deceiver and linguistic analysis reviews the structure of utterances from a potential deceiver. This prototype, complete with explanations, was utilized in two experiments that examined the effects of access to the prototype, accuracy level of the prototype, user training in deception detection, and novice or professional lie-catcher status of the users.Use of the prototype system was found to significantly improve professional and novice accuracy rates and confidence alignment. Training was found to have no effect on novice accuracy rates. Accuracy level of the prototype significantly elevated accuracy rates and confidence alignment among novices; however, this improvement was imperceptible to the novices. Novices using the prototype performed on a level equivalent to professionals using the prototype. Neither professional nor novice users of the prototype exceeded the performance of the prototype system alone. Implications of these findings include emphasizing the development of computer-based tools to detect deception and defining a new role for human users of such tools.

Developing conceptual frameworks for structuring legal knowledge to build knowledge-based systems

Deedman, Galvin Charles 05 1900 (has links)
This dissertation adopts an interdisciplinary approach to the field of law and artificial intelligence. It argues that the conceptual structuring of legal knowledge within an appropriate theoretical framework is of primary importance when building knowledge-based systems. While technical considerations also play a role, they must take second place to an in-depth understanding of the law. Two alternative methods of structuring legal knowledge in very different domains are used to explore the thesis. A deep-structure approach is used on nervous shock, a rather obscure area of the law of negligence. A script-based method is applied to impaired driving, a well-known part of the criminal law. A knowledge-based system is implemented in each area. The two systems, Nervous Shock Advisor (NSA) and Impaired Driving Advisor (IDA), and the methodologies they embody, are described and contrasted. In light of the work undertaken, consideration is given to the feasibility of lawyers without much technical knowledge using general-purpose tools to build knowledge-based systems for themselves.

Computer software for the control of potato storage environment

Landry, Jacques-André January 1994 (has links)
Much research has proven that computer controlled vegetable storage can achieve better storage conditions than traditional control systems. During the last 10 years, the use of microcomputer-based environmental control systems has become commonplace. However, to take full advantage of this computerization of the control process, it is not enough only to program the control functions that are performed by normal analog equipment. New and better control strategies must be developed. Recent advances in computer technology have made possible the development of expert systems; a branch of artificial intelligence. One of the advantages of developing such a system is that it provides a reasoning tool which approaches the level of proficiency human experts exhibit in that field. The application of new control methods using expert systems has been extensively demonstrated for greenhouse environments. However, the application of expert systems for the control of vegetable storage is still to be investigated. In the first phase of this project, the development and implementation of a sophisticated control software, using a conventional algorithm-based programming language, were achieved. Throughout the three years of experimentation in an industrial potato storage, the software proved to be appropriate for the control of storage environmental parameters (temperature and relative humidity). During the second phase, the application of an expert system for the on-line control of potato storage was explored. The development of a rule-based expert system, that could replace the conventional algorithm-based control routines was achieved. The integration of the expert system into the control software will result in a highly efficient control software, which can easily be maintained and improved as new knowledge emerges. The use of an expert system will also render possible the representation of heuristic knowledge in the form of rules, which was not possible with the use of conven
