16 Διεθνή Επιςτημονικά ςυνζδρια FUNEUS: A neurofuzzy approach based on fuzzy adaline neurons Koutsojannis C, Hatzilygeroudis I. STAIRS 2006, Riva del Garda (August 2006 Italy). Today hybrid computing is a popular framework for solving complex problems. If we have knowledge expressed in rules, we can build an Expert System, and if we have data, or can learn from stimulation (training) then we can use Artificial Neural Networks. In this paper we present the FUzzy NEUrule System (FUNEUS) which is a Neuro Fuzzy approach based on fuzzy Adaline neurons and uses Differential Evolution for optimization of membership functions. According to previous Neuro-fuzzy approaches and a well-defined hybrid system HYMES, FUNEUS is an attempt to the direction for integration of neural and fuzzy components with Differential evolution. Despite the fact that it remains difficult to compare neurofuzzy systems conceptually and evaluate their performance, early experimental results proved a promising performance and the need for further evaluation in other application domains.

17 Education in Computers Conquers Health Care Constantinos Koutsojannis, Ioanna Kontomina, Georgia Margari, Evripidis Doulias and Maria Katsardi, Professional s Technophobia, Pci 2007 (2007), May 2007, Patras, Greece Although several studies in different countries have explored the extent to which health care professionals use biomedical technology as well as the computer and the internet, few researches are available on this subject in Greece. The potentially high rate of resistance to new technology has been summarized as Technophobia in the literature. The aim of this study was to explore and to overcome Technophobia barriers to new technology and promote the learning process training nurses to computer and internet. Two hundreds nurses of the main Hospitals of Western Greece, participated during last tree years, to a 2- month course, including basic computer skills that designed to assist the faculty in becoming comfortable computer users. The applications addressed included: introduction to windows, electronic mail, word processing, presentation and database applications, library on-line searches of literature databases and introduction to internet browsers. The participants completed a-16 item questionnaire before and after the course while SPSS 14.0 software was used for data analysis. The mean age for the participant nurses were 35.5 years. Overall, 32.6% of the entire sample could use the computer, 67.4% could not.slightly more than two thirds (75 %) of the entire nurses had never used the internet, and 25 % had. The total improvement of new technology familiarization was statistically significant (usually p<0.0001). In conclusion clinical nurses in Greece have not fully utilised the opportunity that the use of computer and internet offer for nursing education. Improved efforts such as inclusion of more computer education courses in nursing curricular or in life long learning programs additionally with establishment of computer laboratories are required to increase the health care professional s access to computers and internet, conquering Technophobia and computer anxiety.

18 Fuzzy-Evolutionary Synergism in an Intelligent Medical Diagnosis System Constantinos Koutsojannis, Ioannis Hatzilygeroudis. KES 06 International Conference on Knowledge-Based & Intelligent Information & Engineering Systems 9-11 October 2006 Bournemouth, UK Αccepted for Publication In this paper, we present the design, implementation and evaluation of HIGAS, a hybrid intelligent system that deals with diagnosis and treatment consultation of acid-base disturbances based on blood gas analysis data. The system mainly consists of a fuzzy expert system that incorporates an evolutionary algorithm in an off-line mode. The diagnosis process, the input variables and their values were modeled based on expert s knowledge and existing literature. The fuzzy rules are organized in groups to be able to simulate the diagnosis process. Differential evolution algorithm is used to fine-tune the membership functions of the fuzzy variables. Medium scale experimental results show that HIGAS does better than its non-hybrid version, non-experts and other previous computer-based approaches.

Koutsojannis Procs of the IASTED International Conference on Web-Based Education (WBE-2005), Feb , 2005, Grindelwald, Switzerland, In this paper, we present a web-based intelligent education system to help students and tutors in the context of an AI course. We concentrate on the knowledge management and student evaluation aspects of the system. Knowledge management mainly refers to test questions construction and management. Student evaluation refers to the evaluation of the knowledge level of a student with regards to taught concepts. A rule-based expert system helps in student evaluation. A number of statistics provided by the system give valuable information to the tutor. Λζξεισ Κλειδιά: Web-based education, student evaluation, expert systems, knowledge management. 16

20 Combining Expert Systems and Adaptive Hypermedia Technologies in a Web Based Educational System Ι. Hatzilygeroudis, Ch. Giannoulis and C. Koutsojannis, Proceedings of the 5 th IEEE International Conference on Advanced Learning Technology (ICALT-2005), Kaohsiung, Taiwan, July 5-8, 2005, IEEE Computer Society, In this paper, we present a web-based intelligent education system to help students in the context of an AI course. We concentrate on the adaptivity and student evaluation aspects of the system. Adaptivity refers to the capability of the system to adapt teaching to student needs, specified by the student model characteristics. Student evaluation refers to the evaluation of the knowledge level of a student, which is one of the most important characteristics, with regards to taught concepts. Adaptive hypermedia techniques, like graphical link annotation, and an intelligent technique, i.e. a rule-based expert system, are used to achieve the above goals. An evaluation of the system showed encouraging results as far as its usability and learning are concerned. Knowledge-based Αdaptive Αssessment in a Webbased Intelligent Educational System Hatzilygeroudis, I., Koutsojannis, C., Papavlasopoulos, C., Prentzas, J Proceedings - Sixth International Conference on Advanced Learning Technologies, ICALT 2006, art. no , pp In this paper, we present an adaptive and intelligent webbased educational system that uses AI techniques for personalized assessment of the learners. More specifically, we focus on a mechanism for on-line creation of a useradapted test, which can be used alongside the predetermined test. The user can ask for such a test any time he/she is willing to do so, even if he/she has not studied all predetermined concepts of a learning goal. A small rule base is used by an expert system inference engine for making decisions on the difficulty level of the exercises to be included in the test. This is based on the evaluation of the learner during concept studying. Adaptive assessment of the learner can be repeatedly used until there is no further need. Another small rule-base is used for deciding on whether a new test is suggested or not. This is based on the learner s previous test assessment results. Preliminary 17
