Published: November 2017

Στην παρούσα εισήγηση εξετάζουμε την περίπτωση των χαρισματικών παιδιών και την θέση τους στο χώρο της εκπαίδευσης. Για τα χαρισματικά παιδιά έχουν δοθεί πολλοί ορισμοί (εθνικοί, ειδικής παιδαγωγικής, λειτουργικοί, διευκρινιστικοί) και μάλιστα η «χαρισματικότητα», όπως χαρακτηριστικά ονομάζεται, αναγνωρίστηκε μετά από 34 χρόνια προσπάθειας. Διάφοροι επιστήμονες, όπως ο Renzulli, ο Gardner, ο Heller προσπάθησαν να προσεγγίσουν και να ορίσουν τη χαρισματικότητα και τα χαρισματικά παιδιά. Σκοπός της έρευνας είναι να καθοριστούν τα χαρακτηριστικά των χαρισματικών παιδιών, οι δυσκολίες που αντιμετωπίζουν σε κάθε επίπεδο, τα αίτια και η εκπαίδευση των παιδιών αυτών. Οι πρακτικές της διαφοροποιημένης διδασκαλίας και του ευέλικτου αναλυτικού προγράμματος δέχονται κριτική ως προς την δυσκολία να αξιολογηθεί η εφαρμογή τους κατά την εκπαίδευση των χαρισματικών παιδιών. Συμπερασματικά, τα χαρισματικά παιδιά ή οι μαθητές, με υψηλές ικανότητες χρήζουν σεβασμό και αντιμετώπιση όχι ως μειοψηφία ούτε με μια ελιτιστική νοοτροπία. Το ζητούμενο είναι να δούμε πόσα παιδιά έχουν ανάγκη από προσαρμοσμένη εκπαίδευση, είτε έχουν υψηλή αντιληπτική ικανότητα, είτε δεν έχουν. Αν μπορούν να αποκτήσουν γνώσεις από μια εκπαίδευση προσαρμοσμένη στις ανάγκες τους, διαθεματική, με εμπλουτισμό της ύλης, προσαρμογή του Αναλυτικού Προγράμματος, τότε η εκπαίδευση θα είναι αποτελεσματική καθώς θα καλύπτει τις ανάγκες τους.
Ειδικές μαθησιακές δυσκολίες και παραβατική συμπεριφορά: Βιβλιογραφική οριοθέτηση και αναζήτηση σχέσεων στον πολιτισμό του σχολείου και της οικογένειας

Published: November 2017

Η εργασία επιδιώκει να εξετάσει βιβλιογραφικά τους όρους ειδικές μαθησιακές δυσκολίες (ΕΜΔ) και παραβατική συμπεριφορά, να αναζητήσει με ποιον τρόπο συνδέονται ο πολιτισμός του σχολείου και της οικογένειας. Οι ΕΜΔ (δυσλεξία) εμφανίζονται μέσα στη σχολική τάξη κι αποτελούν δυσχέρειες στην ανάγνωση, τη γραφή, την ορθογραφία και τα μαθηματικά. Η φροντίδα ή η έλλειψη υποστήριξης, καταγράφεται τόσο στο περιεχόμενο του πολιτισμού του σχολείου όσο και της οικογένειας. Η σχολική αποτυχία εκλαμβάνεται από τον περίγυρο των παιδιών ως αδιαφορία και τα ίδια τα παιδιά σταδιακά οδηγούνται στον κοινωνικό αποκλεισμό. Μελέτες έχουν δείξει (Χρηστάκης, 2013) πως τα άτομα με ειδικές εκπαιδευτικές ανάγκες, είναι περισσότερο επιρρεπή στη χρήση ουσιών, στην απότομη και βίαιη συμπεριφορά σε σχέση με άλλους συνομηλίκους τους. Η αδυναμία κατανόησης των ορίων (προσωπικών και κοινωνικών), καθώς και η ελλιπής ενημέρωσή τους για τις αρνητικές επιπτώσεις των επιλογών τους, καταγράφεται σε μια σειρά παραβατικών συμπεριφορών.

Authors: Μπικάκης Ιωάννης 
Published: November 2017

Τα σχολεία στις μέρες μας, ενστερνιζόμενα την αρχή της συμπεριληπτικής εκπαίδευσης, περιλαμβάνουν στις τάξεις τους ένα μεγάλο πλήθος μαθητών με διαφορετικά χαρακτηριστικά. Κάποιοι από αυτούς μπορεί να παρουσιάζουν προβλήματα συμπεριφοράς. Η συγκεκριμένη κατηγορία μαθητών σύμφωνα με τον Farrell (2006), θέτει σε συνεχή πρόκληση τους γονείς, τους δασκάλους και όλες τις εκπαιδευτικές και υποστηρικτές αρχές.Σκοπός της έρευνας είναι να περιγράψει τους λόγους εκδήλωσης της επιθετικής συμπεριφοράς αυτών των μαθητών. Να αναφέρει πιθανά προβλήματα συνοσηρότητας και να προτείνει στρατηγικές αντιμετώπισης του μαθητή από τους καθηγητές του σχολείου. Επίσης προτείνει και ένα συγκεκριμένο συμβόλαιο τιμής που είναι κατάλληλο για μαθητές Β΄ βάθμιας εκπαίδευσης.Για τη σύνταξη της μελέτης χρησιμοποιήθηκε υλικό από εργασία του συγγραφέα που έγινε στα πλαίσια σχετικού μαθήματος του μεταπτυχιακού προγράμματος Ειδικής Αγωγής του Πανεπιστημίου Λευκωσίας στο οποίο είναι φοιτητής. Χρησιμοποιήθηκαν επίσης πανεπιστημιακά συγγράμματα, εγχώρια και διεθνής βιβλιογραφία σχετική με τα συναισθηματικά και συμπεριφορικά προβλήματα των μαθητών.Είναι πολλοί οι εκπαιδευτικοί που έχουν στις τάξεις τους μαθητές με συμπεριφορικά προβλήματα και είναι σημαντικό γι’ αυτούς να γνωρίζουν τις παραμέτρους που διέπουν τη συμπεριφορά ενός παιδιού, όπως επίσης και τους τρόπους αντιμετώπισης της παραβατικής συμπεριφοράς εντός του χώρου του σχολείου.

Purpose To determine the prevalence of osteonecrosis (ON) in children following treatment of acute lymphoblastic leukaemia (ALL), characterise these cases and review treatment methods. Methods All children diagnosed and treated for ALL between 01 January 2003 and 31 December 2013 at our centre were retrospectively reviewed. Logistic regression was used to investigate risk factors for ON occurrence. Results Of 235 children treated for ALL, 48/235 (20.4%) children suffered musculoskeletal symptoms necessitating radiological investigation. A total of 13 (5.5%) had MRI-diagnosed ON, with a median diagnosis time of 12 months (interquartile range 10 to 14) following initiation of chemotherapy. ON affected 40 joints in 13 children. The most commonly involved joints were hips (14 joints in eight patients) and knees (12 joints in seven patients). Older age at ALL diagnosis was associated with significantly increased risk of development of ON per year (odds ratio 1.35, 95% confidence interval 1.17 to 1.57, p < 0.001). Eight children underwent at least one surgical intervention. Joint arthroplasty was undertaken in nine joints of four children at a mean age of 18.3 years. All patients who underwent hip arthroplasty had previously received core decompression, with a mean time of 27.8 months (18 to 33) between treatments. Conclusions ON is a significant complication of ALL treatment. Our results suggest risk stratification for development of ON by age, and targeted monitoring of high-risk joints is possible. ON treatment is varied with little evidence base.

Published: November 2017

AbstractThis study was undertaken to quantify the additional increase in diet‐induced oxygen uptake after exhaustive high‐intensity intermittent exercise (HIIE), consisting of 6–7 bouts of 20‐sec bicycle exercise (intensity: 170% ) with a 10‐sec rest between bouts. Using a metabolic chamber, the oxygen uptake of ten men was measured from 10:30 am to 07:00 am the next day on two separate days with or without HIIE, with lunch (12:00) and supper (18:00) (Diet experiment). On two other days, the oxygen uptake of six different subjects was measured from 10:30 to 16:00 with or without HIIE, but without meals (Fasting experiment). Ten minutes of exercise at 50% preceded the HIIE in both experiments; EPOC (excess postexercise oxygen consumption) after HIIE was found to wear off before 12:00 in both experiments. In the Diet experiment, oxygen uptake during HIIE and EPOC were 123.4 ± 12.0 and 115.3 ± 32.3 mL·kg−1, respectively. Meals elevated resting oxygen uptake on both days, but those on the HIIE day were significantly higher than on the control day. This enhanced diet‐induced oxygen uptake (difference in resting oxygen uptake from 12:00–23:00 between HIIE and control day: ΔDIT) was 146.1 ± 90.9 mL·kg−1, comparable to the oxygen uptake during the HIIE and EPOC. The ΔDIT was correlated with subjects’ (52.1 ± 6.6 mL·kg−1·min−1) (r = 0.76, n = 10, P < 0.05). We concluded that HIIE enhances diet‐induced oxygen uptake significantly, and that it is related to the cardiorespiratory fitness.

Therapeutic Anticoagulation in Patients with Primary Brain Tumors or Secondary Brain Metastasis
Authors: Lin Richard J. , Green David L. , Shah Gunjan L. 
Published: November 2017

Abstract

Patients with primary or metastatic brain tumors are at increased risk of developing venous thromboses. However, the potential benefit of therapeutic anticoagulation in these patients must be weighed against the deadly complication of intracranial hemorrhage. In this review, we summarize available evidence and recent studies of intracranial bleeding risks in primary and metastatic tumors and the impact of therapeutic anticoagulation. We find that for the majority of primary and treated metastatic brain tumors, the risk of spontaneous bleeding is acceptable and not further increased by careful therapeutic anticoagulation with low molecular weight heparin or direct oral anticoagulants, although thrombocytopenia (platelet count less than 50,000/μL) and other coagulopathies are relative contraindications. Patients with brain metastasis from melanoma, renal cell carcinoma, choriocarcinoma, thyroid carcinoma, and hepatocellular carcinoma have a higher tendency to bleed spontaneously than noted in patients with other malignancies, and thus warrant routine brain imaging and alternative strategies such as inferior vena cava filter placement in the acute setting of venous thromboembolism before consideration of therapeutic anticoagulation.

Implications for Practice
Malignant gliomas are associated with increased risks of both venous thromboses and intracranial hemorrhage, but the additional bleeding risk associated with therapeutic anticoagulation appears acceptable, especially after treatment of primary tumors. Most patients with treated brain metastasis have a low risk of intracranial hemorrhage associated with therapeutic anticoagulation, and low molecular weight heparin is currently the preferred agent of choice. Patients with untreated brain metastasis from melanoma, renal cell carcinoma, thyroid cancer, choriocarcinoma, and hepatocellular carcinoma have a higher propensity for spontaneous intracranial bleeding, and systemic anticoagulation may be contraindicated in the acute setting of venous thromboembolism.

Authors: Singh Bharat , Sharma Ram A. 
Published: November 2017

Background:Pyrrolizidine alkaloids (PAs) are a group of plant secondary metabolites which protect the plants from biotic stresses by stimulating defense mechanisms as well as adaptability. The pyrrolizidine alkaloids widely occur in members of Boraginaceae family. This review paper describes about the structural properties of various PAs isolated from various Indian Heliotropium species and their biological and pharmacological activities.Methods:Authors surveyed the per-reviewed research, review papers and bibliographic databases and incorporated in this review paper. We have focused our attention on the answers of reviewed questions. The main themes and characteristics of reviewed papers have been described in this review paper.Results:Twenty three species of Heliotropium genus were reviewed critically and have included in this review paper. The review paper contains the critical information of ethnomedicinal properties of each species of Heliotropium genus, the occurrence of pyrrolizidine alkaloids, the biological and pharmacological properties of pyrrplizidine alkaloids. So many pyrrolizidine alkaloids and their N-oxides possess anticancer activity. Some PAs have demonstrated cytotoxic effects also.Conclusion:The findings of this review paper validate the significance of pyrrolizidine alkaloids, their occurrence and biosynthesis in Heliotropium species, as well as their biological and pharmacological properties.
Olive Leaf Extracts Act as Modulators of the Human Immune Response
Authors: Magrone Thea , Spagnoletta Anna , Salvatore Rosaria , Magrone Manrico , Dentamaro Francesco , Russo Matteo A. , Difonzo Graziana , Summo Carmine , Caponio Francesco , Jirillo Emilio 
Published: November 2017

Background:
Olive tree leaves have been used in the Mediterranean area as traditional
medicine in virtue of their healthy effects. Olive leaf extracts (OLEs) contain higher amounts of polyphenols
than those detected in the extra virgin olive oil and fruit. Several lines of evidence support the
cardioprotective, anti-oxidant and anti-inflammatory activities exerted by OLEs.

Methods:
Peripheral blood mononuclear cells from twenty-five healthy donors were cultured in the
presence of 3 µg of two OLE extracts, extract A (resuspended in water) and extract B (resuspended in
70% ethanol). After harvesting, cell pellets were used for cytofluorimetric phenotyping, while supernatants
were assayed for cytokine release by means of ELISA. Furthermore, in the same supernatants
nitric oxide (NO) content was determined.

Results:
Both extracts, but especially extract A, increased absolute numbers of CD8+ and natural killer
(NK) cells. In addition, an increased production of interferon (IFN)-γ by both extracts as an expression
of T helper (h)1 activation was observed. Finally, both extracts enhanced NO release.

Conclusion:
OLEs, and mostly extract A, are able to in vitro modify healthy human immune response
by increasing IFN-γ production which seems to be associated to the higher absolute numbers of CD8+
and NK cells and this may suggest a reinforcement of the anti-tumor activity. Furthermore, increased
levels of NO may indicate the potential cardioprotective effects exerted by OLEs in virtue of their vasodilation
dependent activity. Finally, OLEs are able to maintain the equilibrium between T regulatory cells
and Th17 cells as evidenced by unmodified levels of interleukin (IL)-IL-10 and IL-17, respectively.

In the light of these results, OLEs are potential therapeutic compounds for the treatment of chronic
inflammatory disease, also preventing cardiovascular event outcome.

Published: November 2017

Introduction:
This paper presents results from a set of numerical studies on the cracked reinforced concrete column at high temperature.

Methods:
The macroscopic finite element model used in the accounts analysis for high temperature properties of constitutive materials. The validity of the model is established by comparing the predictions from numerical analysis with the data measured in the fire test.

Result and Conclusion:
Data from the test indicated that the temperature of rebar in column with cracks is 57% ~ 130% higher than that without cracks under the same condition, and different types of crack had significant influence on the bearing capacity of column. These results from parametric studies were utilized to propose ultimate bearing capacity of cracked reinforced concrete column.
Studies on Static Frictional Contact Problems of Double Cantilever Beam Based on SBFEM
Authors: Chaolei Zhu , Qian Gao , Zhiqiang Hu , Gao Lin , Jingzhou Lu 
Published: November 2017

Introduction:
The frictional contact problem is one of the most important and challenging topics in solids mechanics, and often encountered in the practical engineering.

Method:
The nonlinearity and non-smooth properties result in that the convergent solutions can't be obtained by the widely used trial-error iteration method. Mathematical Programming which has good convergence properties and rigorous mathematical foundation is an effective alternative solution method, in which, the frictional contact conditions can be expressed as Non-smooth Equations, B-differential equations, Nonlinear Complementary Problem, etc.

Result:
In this paper, static frictional contact problems of double cantilever beam are analyzed by Mathematical Programming in the framework of Scaled Boundary Finite Element Method (SBFEM), in which the contact conditions can be expressed as the B-differential Equations.

Conclusion
The contact forces and the deformation with different friction factors are solved and compared with those obtained by ANSYS, by which the accuracy of solving contact problems by SBFEM and B-differential Equations is validated.
