Επιστημονικές Δραστηριότητες 2008-2011του Τμήματος Πληροφορικής

του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης

Σεπτέμβριος 2011


ΠΡΟΛΟΓΟΣ

Όπως ο τίτλος περιγράφει με εύγλωττο τρόπο, το τεύχος αυτό συνοψίζει τις επιστημονικές συγγραφικές δραστηριότητες του Τμήματος Πληροφορικής του ΑΠΘ για την περίοδο 2008-2011. Το τεύχος αποτελεί τη δεύτερη προσπάθεια αυτού του είδους, σε συνέχεια του αντίστοιχου τεύχους για την περίοδο 2000-2007.

Με τη γενικότερη εκπαιδευτική και αναπτυξιακή δράση του, το τμήμα κτίζει τη δημόσια εικόνα του και κατατάσσεται μεταξύ των πρώτων αντίστοιχων σχολών πληροφορικής και υπολογιστών στην Ελλάδα, όπως αποδεικνύεται από τις προτιμήσεις των εισαγόμενων φοιτητών σε πανελλήνιο επίπεδο. Άλλωστε η αποτελεσματικότητα αυτή απεικονίζεται και σε διεθνές επίπεδο, καθώς το τμήμα φιγουράρει μεταξύ των 200 πρώτων αντίστοιχων τμημάτων σύμφωνα με διεθνείς κατατάξεις, γεγονός αξιοσημείωτο όσο σχετικό νόημα και αν έχουν αυτές οι κατατάξεις. Μάλιστα, τα επιτεύγματα αυτά κατακτήθηκαν με σημαντικά μικρότερη χρηματοδότηση από αντίστοιχα αδελφά τμήματα, καθώς ακόμη με ελλείψεις σε προσωπικό και υποδομές. Για τους λόγους αυτούς οι επιτυχίες του τμήματος αποκτούν μεγαλύτερη αξία και δυναμική.

Τα διδακτικό, τεχνικό και διοικητικό προσωπικό είναι υπερήφανα για το έργο αυτό, που αποτελεί παράδειγμα αφοσίωσης στο ακαδημαϊκό καθήκον αλλά κυρίως κίνητρο για τους προπτυχιακούς και μεταπτυχιακούς φοιτητές μας με σκοπό την εμβάθυνση στην επιστήμη και την απόκτηση εφοδίων για την επαγγελματική ένταξη στην κοινωνία και την οικονομία της γνώσης.
