Optinalysis, as a method of symmetry detection, is a new advanced computational algorithm that intrametrically (within elements) or intermetrically (between elements) computes and compares two or more multivariate sequences in an unclustered or clustered manner as a mirror-like reflection of each other (optics-like manner), hence the name is driven. Optinalysis is based by the principles of reflection and moment about a symmetrical line which detects symmetry that reflects a similarity measurement. Optinalysis is suitable for quantitative and qualitative data types, with or without replications, provided it conform the algorithmic requirements there provided. Optinalysis can be organized for geometrical, geostatistical and statistical analysis in one-way, two-way, or three-way approach. A simulation comparisons shows that Optinalysis is a simple alternative approach of multivariate analysis of sociometric, demographic, socio-demographic, psychometric, ecological, experimental, genomic, nanoparticle and shape morphometric data. Optinalysis of these data matrix shows very similar results or conclusions with some multivariate analysis such as skewness measure, one-way ANOVA, paired t-test, one sample t-test, Tukey’s multiple comparisons, BLAST sequence algorithmic analysis (percentages of identity, similarity, gabs, and positives, and the Needleman-Wunsch score), and Riemannian distance.

Optinalysis, as a method of symmetry detection, is a new algorithm that intrametrically (within elements or variables) or intermetrically (between elements or variables) computes and compares two or more univariate or multi-clustered or multivariate sequences as a mirror-like reflection of each other (optics-like manner), hence the name is driven. Optinalysis is based by the principles of reflection and moment about a symmetrical line which detects symmetry that reflects a similarity measurement. This proposed methodology was validated in comparison with Pearson method of skewness detection, and also with some algorithms for pairewise alignment and comparison of genomic sequences (Needle, Stretcher, Water, Matcher) on EMBL-EBI website. A results comparison shows that optinalysis is more advance, more sensitive, more inferential and simple alternative approach of skewness detection and pairewise sequence comparison.

Η παρούσα διδακτορική διατριβή μελετά θέματα κοινωνικού κεφαλαίου, υγείας και προαγωγής της υγείας, καθώς και πολιτικών για την προαγωγή της υγείας στην Τριτοβάθμια Εκπαίδευση. Πιο συγκεκριμένα η διδακτορική αυτή διατριβή εξετάζει πώς οι πολιτικές για την προαγωγή της υγείας, οι οποίες αναπτύσσονται στην Τριτοβάθμια Εκπαίδευση, συνδέονται με το κοινωνικό κεφάλαιο των φοιτητών και επηρεάζουν την υγεία τους με διαφορετικούς τρόπους. Επίσης, ο σκοπός της παρούσας διδακτορικής διατριβής είναι να διερευνήσει πώς οι φοιτητές υιοθετούν τις πολιτικές για την προαγωγή της υγείας στο Πανεπιστήμιο φοίτησής τους με βάση το κοινωνικό τους κεφάλαιο. Για τη διεξαγωγή της εμπειρικής έρευνας χρησιμοποιήθηκε το ανώνυμο γραπτό ερωτηματολόγιο. Η επεξεργασία των δεδομένων πραγματοποιήθηκε με το στατιστικό πακέτο SPSS 24 και χρησιμοποιήθηκαν οι στατιστικοί δείκτες: t-test, One Way Anova και Παραγοντική Ανάλυση, ενώ στα ποιοτικά δεδομένα του ερωτηματολογίου εφαρμόστηκε θεματική ανάλυση. Το δείγμα της έρευνας αποτελείτο από 445 τεταρτοετείς φοιτητές της Σχολής Ανθρωπιστικών και Κοινωνικών Επιστημών του Πανεπιστημίου Πατρών, οι οποίοι φοιτούσαν στο εαρινό εξάμηνο 2017-2018. Το μέγεθος του δείγματος θεωρήθηκε αντιπροσωπευτικό του πληθυσμού που διερευνήθηκε. Με βάση τα αποτελέσματα της εμπειρικής έρευνας, διαπιστώθηκε ότι το κοινωνικό κεφάλαιο των φοιτητών επηρεάζει σε μεγάλο βαθμό την αποδοχή και την υιοθέτηση των πολιτικών για την προαγωγή της υγείας οι οποίες προωθούνται από το Πανεπιστήμιο Πατρών, καθώς και τις αντιλήψεις τους σε θέματα σχετικά με την υγεία και την προαγωγή της υγείας στο Πανεπιστήμιο. Αυτή η έρευνα κατέδειξε ότι οι φοιτητές πρέπει να δημιουργήσουν ένα ισχυρό κοινωνικό κεφάλαιο στο Πανεπιστήμιό τους. Για να επιτευχθεί αυτό, τo Πανεπιστήμιο θα μπορούσε να βοηθήσει τους φοιτητές και τις φοιτήτριες να αναπτύξουν το κοινωνικό τους κεφάλαιο, για παράδειγμα δημιουργώντας δεσμούς μεταξύ του προσωπικού του Πανεπιστημίου και των φοιτητών, και παράλληλα προωθώντας δραστηριότητες οι οποίες να ενισχύουν την κοινωνική αλληλεπίδραση στην πανεπιστημιακή κοινότητα.

ABSTRACT Aim The E4D Compare software is an innovative tool that provides immediate feedback to students’ projects and competencies. It should provide consistent scores even when different scanners are used which may have inherent subtle differences in calibration. This study aimed to evaluate potential discrepancies in evaluation using the E4D Compare software based on four different NEVO scanners in dental anatomy projects. Additionally, correlation between digital and visual scores was evaluated. Materials and methods Thirty-five projects of maxillary left central incisors were evaluated. Among these, thirty wax-ups were performed by four operators and five consisted of standard dentoform teeth. Five scores were obtained for each project: one from an instructor that visually graded the project and from four different NEVO scanners. A faculty involved in teaching the dental anatomy course blindly scored the 35 projects. One operator scanned all projects to four NEVO scanners (D4D Technologies, Richardson, TX, USA). The images were aligned to the gold standard, and tolerance set at 0.3 mm to generate a score. The score reflected percentage match between the project and the gold standard. One-way ANOVA with repeated measures was used to determine whether there was a significant difference in scores among the four NEVO scanners. Paired-sample t-test was used to detect any difference between visual scores and the average scores of the four NEVO scanners. Pearson's correlation test was used to assess the relationship between visual and average scores of NEVO scanners. Results There was no significant difference in mean scores among four different NEVO scanners [F(3, 102) = 2.27, p = 0.0852 one-way ANOVA with repeated measures]. Moreover, the data provided strong evidence that a significant difference existed between visual and digital scores (p = 0.0217; a pairedsample t-test). Mean visual scores were significantly lower than digital scores (72.4 vs 75.1). Pearson's correlation coefficient of 0.85 indicated a strong correlation between visual and digital scores (p < 0.0001). Conclusion The E4D Compare software provides consistent scores even when different scanners are used and correlates well with visual scores. Clinical significance The use of innovative digital assessment tools in dental education is promising with the E4D Compare software correlating well with visual scores and providing consistent scores even when different scanners are used.

Purpose: The inconsistencies and variations of creatine kinase level due to modifiable and non-modifiable factors were the basis of this study. The aim was to find out the relationships between creatinine and creatine kinase in the blood of somatotypes.    Methods: The 122 males, aged 10 to 20 years, were classified according to their somatotypes. Somatotypes were measured by the ISAK method. By standard laboratory methods, creatinine and creatine kinase estimate. The IBM SPSS version 24 is used for calculation. One way ANOVA followed by post hoc tests was performed to compare the variables among the three groups (p<0.05).   Results: Creatinine level in the blood insignificantly deferred among the three somatotypes. The significant differences (p<0.05) were found in creatine kinase level in the blood and creatinine/creatine kinase ratio among the three dominant Somatotypes. Creatine Kinase was significantly higher in Ectomorphs (212 U/L) than Endomorphs. Ectomorphs and mesomorphs have crossed normal creatine kinase levels (35 -175 U/L). The creatinine/creatine kinase ratio was found highest in endomorphs and lowest in the ectomorphs and significantly differed in three Somatotypes.   Conclusion: Creatinine production remains the same, indicating production of Creatinine is independent of specific body types. A significant higher Creatine Kinase level in Ectomorphs over Endomorphs showed fat content was not associated with it. Significant differences in Creatinine / Creatine Kinase ratio among Somatotypes suggested its relevance between cellular and morphological relationships and might uses as biomarkers.
