    Introduction: Lung cancer is a contemporary issue for our society as it is a serious condition that can significantly affect the quality of life of patients in various physical and psychological aspects. For this reason, it is important to investigate it. Aim: The purpose of this study was to investigate the impact of aerobic exercise on the quality of life in patients with postoperative lung cancer. Material and Method: Literature search for scientific studies was conducted in the Pubmed and Embase databases. Keywords used were (lung cancer or lung neoplasms or lung tumor or lung adenocarcinoma), (aerobic exercise or aerobic training or physical activity or physical exercise), (quality of lie) and (postoperative or post operative or post-surgery or post-surgical) in all possible combinations. Results: The search yielded 7 studies published from 2019-2023 that met the predefined criteria. The literature search revealed that aerobic exercise can help in various areas such as improving pulmonary function (expiratory and inspiratory pressure), muscular strength, sleep, mood, and certain aspects of quality of life and fatigue. Conclusions: Aerobic exercise helps to improve symptoms and quality of life of patients with postoperative lung cancer. However, further research is needed. Εισαγωγή: Ο καρκίνος του πνεύμονα αποτελεί ένα σύγχρονο θέμα για την κοινωνία μας καθώς είναι μια σοβαρή πάθηση που μπορεί να επηρεάσει σημαντικά την ποιότητα των ασθενών σε διάφορους τομείς, σωματικά αλλά και ψυχικά. Γι’ αυτό τον λόγο είναι σημαντικό να διερευνηθεί. Σκοπός: Σκοπός της παρούσας εργασίας υπήρξε η διερεύνηση του θέματος της επίδρασης της αερόβιας άσκησης στην ποιότητα ζωής σε ασθενείς με μετεγχειρητικό καρκίνο του πνεύμονα. Υλικό και Μέθοδος: Η αναζήτηση της βιβλιογραφίας για την εύρεση επιστημονικών μελετών έγινε στις βάσεις δεδομένων Pubmed, Embase και Cinahl. Λέξεις κλειδιά είναι (lung cancer or lung neoplasms or lung tumor or lung adenocarcinoma), (aerobic exercise or aerobic training or physical activity or physical exercise), (quality of life) και (postoperative or post operative or post-surgery or post-surgical) σε όλους τους πιθανούς συνδυασμούς. Αποτελέσματα: Η αναζήτηση κατέληξε σε 7 μελέτες, που δημοσιευτήκαν κατά την περίοδο 2019-2023, που πληρούσαν τα προκαθορισμένα κριτήρια. Μέσα από την αναζήτηση της βιβλιογραφίας διαπιστώθηκε πως η αερόβια άσκηση βοηθα σε διάφορους τομείς όπως για παράδειγμα στην βελτίωση της πνευμονικής λειτουργείας (εκπνευστική και εισπνευστική πίεση), της μυικής δύναμης, τον ύπνο, τη διάθεση και σε ορισμέμένες πτυχές στην ποιότητα ζωής και της κόπωσης. Συμπεράσματα: Η αερόβια άσκηση βοηθά στην βελτίωση συμπτωμάτων αλλά και σε τομείς της ποιότητας ζωής του ασθενή με μετεγχειρητικό καρκίνο του πνεύμονα. Ωστόσο, υπάρχει ανάγκη για περαιτέρω έρευνα.

    παρούσα εργασία έχει σκοπό την ανάλυση του καλλιτεχνικού έργου της Μέλανης Κωνσταντίνου με τίτλο Ecdysis. Ως μέλος μιας Κυπριακής οικογένειας προσφύγων, συζητά για το συλλογικό τραύμα της εισβολής του 1974, το οποίο γίνεται προσωπικό. Το γεγονός αυτό θεωρεί πως τη σημάδεψε και έπλασε τον χαρακτήρα της. Μέσω της εικαστικής δημιουργίας, αναζητά τρόπους εξιλέωσης και αυτοθεραπείας του τραύματος. Η σχέση της με τα ερπετά γίνεται η πηγή έμπνευσης της. Η αλλαγή δέρματος των φιδιών ταυτίζεται με την μέθοδο του πένθους, όπως την επεξηγεί ο Freud. Όσο αναγκαία είναι για το ζώο αυτή η διαδικασία για να μεγαλώσει, να καθαριστεί και να αυτοθεραπευτεί, έτσι είναι και για τον άνθρωπο. Η μεταμόρφωση αυτή συνδέεται με την ψυχολογική και πνευματική αναγέννηση του ατόμου. Δέρματα, λουλούδια και λευκές γάζες (κουρούκλες) γίνονται τα βασικά υλικά για την πράξη της αυτοθεραπείας. Σχεδόν με τελετουργικό τρόπο και μια επαναλαμβανόμενη πρακτική, δημιουργεί επιφάνειες με τυπώματα από τα υγρά των λουλουδιών και γλυπτικές φόρμες από[sp1] υφάσματα. Ταυτόχρονα, φτιάχνει ένα έργο από δέρματα φιδιών με τρόπο που συνδυάζει την παραδοσιακή μέθοδο του κεντήματος και του αργαλειού. Δημιουργίες που συνεχώς αλλάζουν κατά την πάροδο του χρόνου και υπενθυμίζουν την εφήμερη ύπαρξη του ανθρώπου. Ένα σύγχρονο memento mori.

    This thesis refers to information regarding international Global Navigation Satellite Systems (GNSS) and GNSS/CORS permanent station networks. Initially, an overview is presented on global GNSS systems and GNSS/CORS reference station networks, as well as the existing maps in Cyprus. Subsequently, a detailed description of the fieldwork is provided, with a specific focus on the measurement process at various trigonometric points in the Famagusta district. These points were provided by the Department of Land and Surveys (DLS). The measurements were conducted using high-precision GNSS equipment and specialized data processing software, followed by a comparison of the coordinates of the trigonometric points. Throughout the dissertation, deviations between the reference points and measurements taken using different positioning methods and reference coordinate systems were analyzed. Specifically, the reference points were measured using the Real-Time Kinematic (RTK) method based on the CyPOS and CyCLOPS networks, in the CGRS93 and ITRF14 coordinate reference systems, respectively. Additionally, the reference points were measured using static positioning. Στην παρούσα διπλωματική εργασία γίνεται αναφορά σε πληροφορίες σχετικά με τα διεθνή συστήματα δορυφορικής πλοήγησης (GNSS) και τα δίκτυα μόνιμων σταθμών αναφοράς GNSS/CORS. Αρχικά παρουσιάζονται πληροφορίες για τα παγκόσμια συστήματα δορυφορικής πλοήγησης (GNSS) και τα δίκτυα μόνιμων σταθμών αναφοράς GNSS/CORS, καθώς και οι υπάρχοντες χάρτες στην Κύπρο. Έπειτα, γίνεται μια λεπτομερής περιγραφή της διεξαγωγής των εργασιών πεδίου, με ειδική αναφορά στη διαδικασία μέτρησης σε διάφορα τριγωνομετρικά σημεία στην επαρχία Αμμόχωστο. Τα εν λόγω σημεία προσφέρθηκαν από το Τμήμα Κτηματολογίου και Χωρομετρίας (ΤΚΧ). Οι μετρήσεις πραγματοποιήθηκαν χρησιμοποιώντας εξοπλισμό GNSS γεωδαιτικού βαθμού και εξειδικευμένο λογισμικό επεξεργασίας δεδομένων. Στη συνέχεια πραγματοποιήθηκε σύγκριση των συντεταγμένων των τριγωνομετρικών σημείων. Κατά την διάρκεια της πτυχιακής εργασίας, αναλύθηκαν οι αποκλίσεις μεταξύ των σημείων αναφοράς και των μετρήσεων που πραγματοποιήθηκαν με διαφορετικές μεθόδους εντοπισμού και σε διαφορετικά συστήματα αναφοράς συντεταγμένων. Πιο συγκεκριμένα, τα σημεία αναφοράς μετρήθηκαν χρησιμοποιώντας τη μέθοδο RTK (Σχετικός Κινηματικός Εντοπισμός σε πραγματικό χρόνο) με βάση τα δίκτυα CyPOS και CyCLOPS, στα συστήματα αναφοράς συντεταγμένων CGRS93 και ITRF14, αντίστοιχα. Τέλος, τα σημεία αναφοράς μετρήθηκαν με στατικό εντοπισμό. Completed

    Authors: Markou, Kostas;

    Social networks have become an indispensable part of our daily lives, allowing us to connect with friends and family, share experiences and ideas, and stay informed about current events. However, the use of social networks also carries potential risks, particularly with the spread of harmful content such as hate speech, cyberbullying, and fake news. This has led to an increasing need for social network administrators to develop efficient methods for identifying and removing harmful content. Traditional methods for identifying and removing harmful content are often based on manual review and reporting by users, which can be time-consuming and unreliable. As social networks continue to grow in size and complexity, this approach is becoming increasingly challenging, and administrators are turning to machine learning techniques as a more effective solution. Machine learning algorithms can be trained to automatically analyze large amounts of data generated in social networks and identify patterns that distinguish harmful content from normal content. These algorithms can also adapt and evolve over time as new types of harmful content emerge, providing a more dynamic and responsive solution to the problem. This study aims to explore the application of machine learning techniques to classify harmful and normal client data in social networks. The focus will be on developing and evaluating models that can accurately distinguish harmful data from normal data. This will involve the use of various machine learning techniques, such as supervised and unsupervised learning, and feature engineering to extract relevant information from the data. Using unsupervised algorithms aimed at detecting Harmful and Normal clients on social networks, the outcomes of this study have the potential to contribute to the development of more effective solutions for identifying and removing harmful content in social networks. This could ultimately lead to a safer and more secure online environment for users and help to mitigate the negative effects of harmful content on individuals and society as a whole. Completed

    As is known, the inclusion of recycled materials in our daily life helps to reduce the environmental problems that multiply over time. Thus, in concrete as well, the attempt is made to add alternative materials by replacing others more dangerous to nature. Cement is a material that releases a large percentage of carbon dioxide during its production. Also, waste quarry dust is not use again when it makes the end of its construction and fills large areas that could be used in a more environmentally friendly way. So, the inclusion of quarry waste in concrete is a possible alternative solution to the environmental problem. Waste quarry dust concrete presents similar compressive strength reactions with the ordinary concrete. Finally, the size effect for concrete in compressive strength, also applies to the mix with waste quarry dust as well. Ως γνωστό, η ένταξη ανακυκλωμένων υλικών στην καθημερινότητά μας βοηθά στην μείωση των περιβαλλοντικών προβλημάτων που πληθαίνονται με την πάροδο του χρόνου. Έτσι και στο σκυρόδεμα γίνεται η προσπάθεια ένταξης εναλλακτικών υλικών με αντικατάσταση άλλων πιο επιβλαβών προς την φύση. Το τσιμέντο είναι ένα υλικό το οποίο απελευθερώνει μεγάλο ποσοστό διοξειδίου του άνθρακα κατά την παραγωγή του. Επίσης, τα απόβλητα των λατομείων δεν χρησιμοποιούνται ξανά όταν φτάσουν στο τέλος παραγωγής τους και καταλαμβάνουν μεγάλες εκτάσεις που θα μπορούσαν να εκμεταλλευτούν με τρόπο πιο φιλικό προς το περιβάλλον. Έτσι, η ένταξη αποβλήτων του λατομείου στο σκυρόδεμα είναι μία πιθανή εναλλακτική λύση για το περιβαλλοντικό πρόβλημα. Το σκυρόδεμα με απόβλητα των λατομείων προσφέρουν παρόμοιες αντιδράσεις ως προς την θλιπτική αντοχή του με το σύνηθες σκυρόδεμα. Τέλος, η σχέση θλιπτικής αντοχής με το μέγεθος των δοκιμίων ισχύει και στο μείγμα με απόβλητα λατομείων. Completed

    Introduction: Interventions that include the application of cognitive-behavioral therapy have been shown to improve patients' adherence to treatment, as well as their quality of life (Thomas et al., 2014). Cognitive-behavioral therapy is a form of psychotherapy that aims to challenge, examine and replace a patient's negative thoughts and is considered a particularly useful type of treatment in general for patients who live with chronic illnesses and diseases and have difficulty adhering to strict therapeutic regimens. shapes, as well as in alleviating common psychological conditions, such as anxiety and depression. Εισαγωγή: Οι παρεμβάσεις, οι οποίες περιλαμβάνουν την εφαρμογή γνωσιακής-συμπεριφορικής θεραπείας έχει αποδειχθεί ότι βελτιώνουν την συμμόρφωση των ασθενών στη θεραπεία, καθώς και την ποιότητα ζωής τους (Thomas et al., 2014). Η γνωσιακή-συμπεριφορική θεραπεία είναι μια μορφή ψυχοθεραπείας που στοχεύει να προκαλέσει, να εξετάσει και να αντικαταστήσει τις αρνητικές σκέψεις ενός ασθενούς και θεωρείται ένας ιδιαίτερα χρήσιμος τύπος θεραπείας γενικότερα σε ασθενείς, οι οποίοι ζούν με χρόνια νοσήματα και ασθένειες και αντιμετωπίζουν δυσκολίες στην τήρηση αυστηρών θεραπευτικών σχημάτων, καθώς επίσης και στην ανακούφιση κοινών ψυχολογικών καταστάσεων, όπως το άγχος και η κατάθλιψη.

    The Mesopotamian marshes, a unique and ecologically important wetland ecosystem, have experienced significant changes over the past five decades due to various anthropogenic interventions and natural processes. This thesis focuses on analyzing the temporal dynamics and spatial extent of the marshlands using a combination of satellite imagery and remote sensing techniques. The study utilizes a time series of satellite images spanning from 1972 to 2023, providing a comprehensive understanding of the marshes' evolution. The imagery is processed using advanced techniques, including mosaic creation, band extraction, index calculation, and land cover classification. Various indices, such as NDVI, NDWI, NDMI, and MNDWI, are employed to capture the vegetation density, water content, and moisture conditions within the marshes. The classification results reveal significant changes in the marshes' extent and composition over time. The analysis highlights the gradual decline of the marshes from the 1980s, exacerbated by the Iraq-Iran war in the 1980s and subsequent drainage projects. However, a positive trend of restoration is observed from 2014 to 2023, indicating successful conservation efforts. The findings of this study have significant implications for the management and conservation of the Mesopotamian marshes. The integration of satellite imagery, indices, and classification techniques offers a powerful tool for monitoring and assessing the ecosystem's health and identifying key areas for restoration. The study underscores the importance of preserving wetland ecosystems, as they provide essential habitats for diverse flora and fauna, support local communities, and contribute to regional biodiversity and ecological balance. Overall, this thesis contributes to the broader understanding of the Mesopotamian marshes' dynamics and provides valuable insights for policymakers, environmentalists, and researchers working towards the sustainable management and restoration of wetland ecosystems. Τα έλη της Μεσοποταμίας, ένα μοναδικό και οικολογικά σημαντικό υγροτοπικό οικοσύστημα, έχουν υποστεί σημαντικές αλλαγές τις τελευταίες πέντε δεκαετίες λόγω διαφόρων ανθρωπογενών παρεμβάσεων και φυσικών διεργασιών. Η παρούσα πτυχιακή επικεντρώνεται στην ανάλυση της διαχρονικής δυναμικής και της χωρικής έκτασης των ελών χρησιμοποιώντας ένα συνδυασμό δορυφορικών εικόνων και τεχνικών τηλεπισκόπησης. Η μελέτη χρησιμοποιεί μια χρονοσειρά δορυφορικών εικόνων που καλύπτει το χρονικό διάστημα από το 1972 έως το 2023, παρέχοντας μια ολοκληρωμένη κατανόηση της εξέλιξης των ελών. Η επεξεργασία των εικόνων γίνεται με τη χρήση προηγμένων τεχνικών, συμπεριλαμβανομένης της δημιουργίας μωσαϊκού, της εξαγωγής ζωνών, του υπολογισμού δεικτών και της ταξινόμησης της κάλυψης γης. Χρησιμοποιούνται τέσσερις δείκτες, ο NDVI, ο NDWI, ο NDMI και ο MNDWI, για να αποτυπωθούν η πυκνότητα της βλάστησης, η περιεκτικότητα σε νερό και οι συνθήκες υγρασίας εντός των ελών. Τα αποτελέσματα της ταξινόμησης αποκαλύπτουν σημαντικές αλλαγές στην έκταση και τη σύνθεση των ελών με την πάροδο του χρόνου. Η ανάλυση αναδεικνύει τη σταδιακή μείωση των ελών από τη δεκαετία του 1980, η οποία επιδεινώθηκε από τον πόλεμο Ιράκ-Ιράν τη δεκαετία του 1980 και τα επακόλουθα έργα αποξήρανσης. Ωστόσο, παρατηρείται μια θετική τάση αποκατάστασης από το 2014 έως το 2023, γεγονός που υποδηλώνει επιτυχείς προσπάθειες διατήρησης. Τα ευρήματα της παρούσας μελέτης έχουν σημαντικές επιπτώσεις για τη διαχείριση και τη διατήρηση των ελών της Μεσοποταμίας. Η ενσωμάτωση δορυφορικών εικόνων, δεικτών και τεχνικών ταξινόμησης προσφέρει ένα ισχυρό εργαλείο για την παρακολούθηση και την αξιολόγηση της υγείας του οικοσυστήματος και τον εντοπισμό βασικών περιοχών για αποκατάσταση. Η μελέτη υπογραμμίζει τη σημασία της διατήρησης των υγροτοπικών οικοσυστημάτων, καθώς παρέχουν βασικούς βιότοπους για ποικίλη χλωρίδα και πανίδα, στηρίζουν τις τοπικές κοινότητες και συμβάλλουν στην περιφερειακή βιοποικιλότητα και οικολογική ισορροπία. Συνοπτικά, η παρούσα πτυχιακή συμβάλλει στην ευρύτερη κατανόηση της δυναμικής των ελών της Μεσοποταμίας και παρέχει πολύτιμες πληροφορίες για τους υπεύθυνους χάραξης πολιτικής, τους περιβαλλοντολόγους και τους ερευνητές που εργάζονται για τη βιώσιμη διαχείριση και αποκατάσταση των υγροτοπικών οικοσυστημάτων.

    Introduction: Lung cancer is a contemporary issue for our society as it is a serious condition that can significantly affect the quality of life of patients in various physical and psychological aspects. For this reason, it is important to investigate it. Aim: The purpose of this study was to investigate the impact of aerobic exercise on the quality of life in patients with postoperative lung cancer. Material and Method: Literature search for scientific studies was conducted in the Pubmed and Embase databases. Keywords used were (lung cancer or lung neoplasms or lung tumor or lung adenocarcinoma), (aerobic exercise or aerobic training or physical activity or physical exercise), (quality of lie) and (postoperative or post operative or post-surgery or post-surgical) in all possible combinations. Results: The search yielded 7 studies published from 2019-2023 that met the predefined criteria. The literature search revealed that aerobic exercise can help in various areas such as improving pulmonary function (expiratory and inspiratory pressure), muscular strength, sleep, mood, and certain aspects of quality of life and fatigue. Conclusions: Aerobic exercise helps to improve symptoms and quality of life of patients with postoperative lung cancer. However, further research is needed. Εισαγωγή: Ο καρκίνος του πνεύμονα αποτελεί ένα σύγχρονο θέμα για την κοινωνία μας καθώς είναι μια σοβαρή πάθηση που μπορεί να επηρεάσει σημαντικά την ποιότητα των ασθενών σε διάφορους τομείς, σωματικά αλλά και ψυχικά. Γι’ αυτό τον λόγο είναι σημαντικό να διερευνηθεί. Σκοπός: Σκοπός της παρούσας εργασίας υπήρξε η διερεύνηση του θέματος της επίδρασης της αερόβιας άσκησης στην ποιότητα ζωής σε ασθενείς με μετεγχειρητικό καρκίνο του πνεύμονα. Υλικό και Μέθοδος: Η αναζήτηση της βιβλιογραφίας για την εύρεση επιστημονικών μελετών έγινε στις βάσεις δεδομένων Pubmed, Embase και Cinahl. Λέξεις κλειδιά είναι (lung cancer or lung neoplasms or lung tumor or lung adenocarcinoma), (aerobic exercise or aerobic training or physical activity or physical exercise), (quality of life) και (postoperative or post operative or post-surgery or post-surgical) σε όλους τους πιθανούς συνδυασμούς. Αποτελέσματα: Η αναζήτηση κατέληξε σε 7 μελέτες, που δημοσιευτήκαν κατά την περίοδο 2019-2023, που πληρούσαν τα προκαθορισμένα κριτήρια. Μέσα από την αναζήτηση της βιβλιογραφίας διαπιστώθηκε πως η αερόβια άσκηση βοηθα σε διάφορους τομείς όπως για παράδειγμα στην βελτίωση της πνευμονικής λειτουργείας (εκπνευστική και εισπνευστική πίεση), της μυικής δύναμης, τον ύπνο, τη διάθεση και σε ορισμέμένες πτυχές στην ποιότητα ζωής και της κόπωσης. Συμπεράσματα: Η αερόβια άσκηση βοηθά στην βελτίωση συμπτωμάτων αλλά και σε τομείς της ποιότητας ζωής του ασθενή με μετεγχειρητικό καρκίνο του πνεύμονα. Ωστόσο, υπάρχει ανάγκη για περαιτέρω έρευνα.

    παρούσα εργασία έχει σκοπό την ανάλυση του καλλιτεχνικού έργου της Μέλανης Κωνσταντίνου με τίτλο Ecdysis. Ως μέλος μιας Κυπριακής οικογένειας προσφύγων, συζητά για το συλλογικό τραύμα της εισβολής του 1974, το οποίο γίνεται προσωπικό. Το γεγονός αυτό θεωρεί πως τη σημάδεψε και έπλασε τον χαρακτήρα της. Μέσω της εικαστικής δημιουργίας, αναζητά τρόπους εξιλέωσης και αυτοθεραπείας του τραύματος. Η σχέση της με τα ερπετά γίνεται η πηγή έμπνευσης της. Η αλλαγή δέρματος των φιδιών ταυτίζεται με την μέθοδο του πένθους, όπως την επεξηγεί ο Freud. Όσο αναγκαία είναι για το ζώο αυτή η διαδικασία για να μεγαλώσει, να καθαριστεί και να αυτοθεραπευτεί, έτσι είναι και για τον άνθρωπο. Η μεταμόρφωση αυτή συνδέεται με την ψυχολογική και πνευματική αναγέννηση του ατόμου. Δέρματα, λουλούδια και λευκές γάζες (κουρούκλες) γίνονται τα βασικά υλικά για την πράξη της αυτοθεραπείας. Σχεδόν με τελετουργικό τρόπο και μια επαναλαμβανόμενη πρακτική, δημιουργεί επιφάνειες με τυπώματα από τα υγρά των λουλουδιών και γλυπτικές φόρμες από[sp1] υφάσματα. Ταυτόχρονα, φτιάχνει ένα έργο από δέρματα φιδιών με τρόπο που συνδυάζει την παραδοσιακή μέθοδο του κεντήματος και του αργαλειού. Δημιουργίες που συνεχώς αλλάζουν κατά την πάροδο του χρόνου και υπενθυμίζουν την εφήμερη ύπαρξη του ανθρώπου. Ένα σύγχρονο memento mori.

    This thesis refers to information regarding international Global Navigation Satellite Systems (GNSS) and GNSS/CORS permanent station networks. Initially, an overview is presented on global GNSS systems and GNSS/CORS reference station networks, as well as the existing maps in Cyprus. Subsequently, a detailed description of the fieldwork is provided, with a specific focus on the measurement process at various trigonometric points in the Famagusta district. These points were provided by the Department of Land and Surveys (DLS). The measurements were conducted using high-precision GNSS equipment and specialized data processing software, followed by a comparison of the coordinates of the trigonometric points. Throughout the dissertation, deviations between the reference points and measurements taken using different positioning methods and reference coordinate systems were analyzed. Specifically, the reference points were measured using the Real-Time Kinematic (RTK) method based on the CyPOS and CyCLOPS networks, in the CGRS93 and ITRF14 coordinate reference systems, respectively. Additionally, the reference points were measured using static positioning. Στην παρούσα διπλωματική εργασία γίνεται αναφορά σε πληροφορίες σχετικά με τα διεθνή συστήματα δορυφορικής πλοήγησης (GNSS) και τα δίκτυα μόνιμων σταθμών αναφοράς GNSS/CORS. Αρχικά παρουσιάζονται πληροφορίες για τα παγκόσμια συστήματα δορυφορικής πλοήγησης (GNSS) και τα δίκτυα μόνιμων σταθμών αναφοράς GNSS/CORS, καθώς και οι υπάρχοντες χάρτες στην Κύπρο. Έπειτα, γίνεται μια λεπτομερής περιγραφή της διεξαγωγής των εργασιών πεδίου, με ειδική αναφορά στη διαδικασία μέτρησης σε διάφορα τριγωνομετρικά σημεία στην επαρχία Αμμόχωστο. Τα εν λόγω σημεία προσφέρθηκαν από το Τμήμα Κτηματολογίου και Χωρομετρίας (ΤΚΧ). Οι μετρήσεις πραγματοποιήθηκαν χρησιμοποιώντας εξοπλισμό GNSS γεωδαιτικού βαθμού και εξειδικευμένο λογισμικό επεξεργασίας δεδομένων. Στη συνέχεια πραγματοποιήθηκε σύγκριση των συντεταγμένων των τριγωνομετρικών σημείων. Κατά την διάρκεια της πτυχιακής εργασίας, αναλύθηκαν οι αποκλίσεις μεταξύ των σημείων αναφοράς και των μετρήσεων που πραγματοποιήθηκαν με διαφορετικές μεθόδους εντοπισμού και σε διαφορετικά συστήματα αναφοράς συντεταγμένων. Πιο συγκεκριμένα, τα σημεία αναφοράς μετρήθηκαν χρησιμοποιώντας τη μέθοδο RTK (Σχετικός Κινηματικός Εντοπισμός σε πραγματικό χρόνο) με βάση τα δίκτυα CyPOS και CyCLOPS, στα συστήματα αναφοράς συντεταγμένων CGRS93 και ITRF14, αντίστοιχα. Τέλος, τα σημεία αναφοράς μετρήθηκαν με στατικό εντοπισμό. Completed

    Social networks have become an indispensable part of our daily lives, allowing us to connect with friends and family, share experiences and ideas, and stay informed about current events. However, the use of social networks also carries potential risks, particularly with the spread of harmful content such as hate speech, cyberbullying, and fake news. This has led to an increasing need for social network administrators to develop efficient methods for identifying and removing harmful content. Traditional methods for identifying and removing harmful content are often based on manual review and reporting by users, which can be time-consuming and unreliable. As social networks continue to grow in size and complexity, this approach is becoming increasingly challenging, and administrators are turning to machine learning techniques as a more effective solution. Machine learning algorithms can be trained to automatically analyze large amounts of data generated in social networks and identify patterns that distinguish harmful content from normal content. These algorithms can also adapt and evolve over time as new types of harmful content emerge, providing a more dynamic and responsive solution to the problem. This study aims to explore the application of machine learning techniques to classify harmful and normal client data in social networks. The focus will be on developing and evaluating models that can accurately distinguish harmful data from normal data. This will involve the use of various machine learning techniques, such as supervised and unsupervised learning, and feature engineering to extract relevant information from the data. Using unsupervised algorithms aimed at detecting Harmful and Normal clients on social networks, the outcomes of this study have the potential to contribute to the development of more effective solutions for identifying and removing harmful content in social networks. This could ultimately lead to a safer and more secure online environment for users and help to mitigate the negative effects of harmful content on individuals and society as a whole. Completed

    As is known, the inclusion of recycled materials in our daily life helps to reduce the environmental problems that multiply over time. Thus, in concrete as well, the attempt is made to add alternative materials by replacing others more dangerous to nature. Cement is a material that releases a large percentage of carbon dioxide during its production. Also, waste quarry dust is not use again when it makes the end of its construction and fills large areas that could be used in a more environmentally friendly way. So, the inclusion of quarry waste in concrete is a possible alternative solution to the environmental problem. Waste quarry dust concrete presents similar compressive strength reactions with the ordinary concrete. Finally, the size effect for concrete in compressive strength, also applies to the mix with waste quarry dust as well. Ως γνωστό, η ένταξη ανακυκλωμένων υλικών στην καθημερινότητά μας βοηθά στην μείωση των περιβαλλοντικών προβλημάτων που πληθαίνονται με την πάροδο του χρόνου. Έτσι και στο σκυρόδεμα γίνεται η προσπάθεια ένταξης εναλλακτικών υλικών με αντικατάσταση άλλων πιο επιβλαβών προς την φύση. Το τσιμέντο είναι ένα υλικό το οποίο απελευθερώνει μεγάλο ποσοστό διοξειδίου του άνθρακα κατά την παραγωγή του. Επίσης, τα απόβλητα των λατομείων δεν χρησιμοποιούνται ξανά όταν φτάσουν στο τέλος παραγωγής τους και καταλαμβάνουν μεγάλες εκτάσεις που θα μπορούσαν να εκμεταλλευτούν με τρόπο πιο φιλικό προς το περιβάλλον. Έτσι, η ένταξη αποβλήτων του λατομείου στο σκυρόδεμα είναι μία πιθανή εναλλακτική λύση για το περιβαλλοντικό πρόβλημα. Το σκυρόδεμα με απόβλητα των λατομείων προσφέρουν παρόμοιες αντιδράσεις ως προς την θλιπτική αντοχή του με το σύνηθες σκυρόδεμα. Τέλος, η σχέση θλιπτικής αντοχής με το μέγεθος των δοκιμίων ισχύει και στο μείγμα με απόβλητα λατομείων. Completed

    Introduction: Interventions that include the application of cognitive-behavioral therapy have been shown to improve patients' adherence to treatment, as well as their quality of life (Thomas et al., 2014). Cognitive-behavioral therapy is a form of psychotherapy that aims to challenge, examine and replace a patient's negative thoughts and is considered a particularly useful type of treatment in general for patients who live with chronic illnesses and diseases and have difficulty adhering to strict therapeutic regimens. shapes, as well as in alleviating common psychological conditions, such as anxiety and depression. Εισαγωγή: Οι παρεμβάσεις, οι οποίες περιλαμβάνουν την εφαρμογή γνωσιακής-συμπεριφορικής θεραπείας έχει αποδειχθεί ότι βελτιώνουν την συμμόρφωση των ασθενών στη θεραπεία, καθώς και την ποιότητα ζωής τους (Thomas et al., 2014). Η γνωσιακή-συμπεριφορική θεραπεία είναι μια μορφή ψυχοθεραπείας που στοχεύει να προκαλέσει, να εξετάσει και να αντικαταστήσει τις αρνητικές σκέψεις ενός ασθενούς και θεωρείται ένας ιδιαίτερα χρήσιμος τύπος θεραπείας γενικότερα σε ασθενείς, οι οποίοι ζούν με χρόνια νοσήματα και ασθένειες και αντιμετωπίζουν δυσκολίες στην τήρηση αυστηρών θεραπευτικών σχημάτων, καθώς επίσης και στην ανακούφιση κοινών ψυχολογικών καταστάσεων, όπως το άγχος και η κατάθλιψη.

    The Mesopotamian marshes, a unique and ecologically important wetland ecosystem, have experienced significant changes over the past five decades due to various anthropogenic interventions and natural processes. This thesis focuses on analyzing the temporal dynamics and spatial extent of the marshlands using a combination of satellite imagery and remote sensing techniques. The study utilizes a time series of satellite images spanning from 1972 to 2023, providing a comprehensive understanding of the marshes' evolution. The imagery is processed using advanced techniques, including mosaic creation, band extraction, index calculation, and land cover classification. Various indices, such as NDVI, NDWI, NDMI, and MNDWI, are employed to capture the vegetation density, water content, and moisture conditions within the marshes. The classification results reveal significant changes in the marshes' extent and composition over time. The analysis highlights the gradual decline of the marshes from the 1980s, exacerbated by the Iraq-Iran war in the 1980s and subsequent drainage projects. However, a positive trend of restoration is observed from 2014 to 2023, indicating successful conservation efforts. The findings of this study have significant implications for the management and conservation of the Mesopotamian marshes. The integration of satellite imagery, indices, and classification techniques offers a powerful tool for monitoring and assessing the ecosystem's health and identifying key areas for restoration. The study underscores the importance of preserving wetland ecosystems, as they provide essential habitats for diverse flora and fauna, support local communities, and contribute to regional biodiversity and ecological balance. Overall, this thesis contributes to the broader understanding of the Mesopotamian marshes' dynamics and provides valuable insights for policymakers, environmentalists, and researchers working towards the sustainable management and restoration of wetland ecosystems. Τα έλη της Μεσοποταμίας, ένα μοναδικό και οικολογικά σημαντικό υγροτοπικό οικοσύστημα, έχουν υποστεί σημαντικές αλλαγές τις τελευταίες πέντε δεκαετίες λόγω διαφόρων ανθρωπογενών παρεμβάσεων και φυσικών διεργασιών. Η παρούσα πτυχιακή επικεντρώνεται στην ανάλυση της διαχρονικής δυναμικής και της χωρικής έκτασης των ελών χρησιμοποιώντας ένα συνδυασμό δορυφορικών εικόνων και τεχνικών τηλεπισκόπησης. Η μελέτη χρησιμοποιεί μια χρονοσειρά δορυφορικών εικόνων που καλύπτει το χρονικό διάστημα από το 1972 έως το 2023, παρέχοντας μια ολοκληρωμένη κατανόηση της εξέλιξης των ελών. Η επεξεργασία των εικόνων γίνεται με τη χρήση προηγμένων τεχνικών, συμπεριλαμβανομένης της δημιουργίας μωσαϊκού, της εξαγωγής ζωνών, του υπολογισμού δεικτών και της ταξινόμησης της κάλυψης γης. Χρησιμοποιούνται τέσσερις δείκτες, ο NDVI, ο NDWI, ο NDMI και ο MNDWI, για να αποτυπωθούν η πυκνότητα της βλάστησης, η περιεκτικότητα σε νερό και οι συνθήκες υγρασίας εντός των ελών. Τα αποτελέσματα της ταξινόμησης αποκαλύπτουν σημαντικές αλλαγές στην έκταση και τη σύνθεση των ελών με την πάροδο του χρόνου. Η ανάλυση αναδεικνύει τη σταδιακή μείωση των ελών από τη δεκαετία του 1980, η οποία επιδεινώθηκε από τον πόλεμο Ιράκ-Ιράν τη δεκαετία του 1980 και τα επακόλουθα έργα αποξήρανσης. Ωστόσο, παρατηρείται μια θετική τάση αποκατάστασης από το 2014 έως το 2023, γεγονός που υποδηλώνει επιτυχείς προσπάθειες διατήρησης. Τα ευρήματα της παρούσας μελέτης έχουν σημαντικές επιπτώσεις για τη διαχείριση και τη διατήρηση των ελών της Μεσοποταμίας. Η ενσωμάτωση δορυφορικών εικόνων, δεικτών και τεχνικών ταξινόμησης προσφέρει ένα ισχυρό εργαλείο για την παρακολούθηση και την αξιολόγηση της υγείας του οικοσυστήματος και τον εντοπισμό βασικών περιοχών για αποκατάσταση. Η μελέτη υπογραμμίζει τη σημασία της διατήρησης των υγροτοπικών οικοσυστημάτων, καθώς παρέχουν βασικούς βιότοπους για ποικίλη χλωρίδα και πανίδα, στηρίζουν τις τοπικές κοινότητες και συμβάλλουν στην περιφερειακή βιοποικιλότητα και οικολογική ισορροπία. Συνοπτικά, η παρούσα πτυχιακή συμβάλλει στην ευρύτερη κατανόηση της δυναμικής των ελών της Μεσοποταμίας και παρέχει πολύτιμες πληροφορίες για τους υπεύθυνους χάραξης πολιτικής, τους περιβαλλοντολόγους και τους ερευνητές που εργάζονται για τη βιώσιμη διαχείριση και αποκατάσταση των υγροτοπικών οικοσυστημάτων.
