Objective: To analyze the effects of neuroendoscopic minimally invasive surgery and small bone window craniotomy hematoma clearance through comparing clinical indicators of the two operation modes and to provide a reference for selection of proper minimally invasive surgery.
Methods: One hundred and twenty-six patients with hypertensive cerebral hemorrhage who received diagnosis and treatment in our hospital between December 2015 and December 2017 were selected and grouped into an observation group (n=63) and a control group (n=63) using random number table. Patients in the observation group were treated by neuroendoscopic surgery, while patients in the control group were treated by small bone window craniotomy. The surgical condition, clinical effect and prognosis of the two groups were analyzed and compared.
Results: Patients in the observation group completed surgery in a shorter time and bled less during operation compared to the control group, and the hematoma clearance rate of the observation group was obviously higher than that of the control group; the differences had statistical significance (P<0.05). The nerve deficiency scale (NDS) scores of the two groups at the postoperative 3rd month were lower than those before surgery (P<0.05), and the activity of daily life (ADL) score at the postoperative 3rd month was higher than that before surgery (P<0.05). The observation group had lower NDS score and higher ADL score compared to the control group, and the differences had statistical significance (P<0.05). The incidence of complications of the observation group was lower than that of the control group after surgery, and the rate of favourable prognosis of the observation group was higher than that of the control group at the postoperative 3rd month (P<0.05).
Conclusion: Neuroendoscopic surgery is more effective and safe, causes less bleeding and has better prognosis and nerve function recovery compared to small bone window craniotomy in the treatment of hypertensive cerebral hemorrhage.

Η αφοσίωση των εκπαιδευτικών αποτελεί σημαντικό εργασιακό παράγοντα, καθόσον σχετίζεται τόσο με με την απόδοσή τους στο πλαίσιο άσκησης του έργου που επιτελούν όσο και με την επίδοση των μαθητών τους. Στην περίπτωση των εκπαιδευτικών ειδικής αγωγής η αφοσίωση αυτή αξιολογείται θετικά διότι επιδίδονται στο απαιτητικό έργο της εκπαίδευσης των μαθητών με ειδικές εκπαιδευτικές ανάγκες και αναπηρία. Δεδομένης της οργανωσιακής και, συνακόλουθα, παιδαγωγικής σημαντικότητας που έχει η αφοσίωση των εκπαιδευτικών ειδικής αγωγής στο σχολείο στο οποίο υπηρετούν, μελετήθηκαν αντίστοιχοι παράγοντες που συμβάλλουν στην αφοσίωση αυτή. Η μελέτη βασίστηκε σε τυχαίο πανελλαδικό δείγμα 375 εκπαιδευτικών ειδικής αγωγής, που υπηρετούσαν στην Α/θμια Εκπαίδευση. Από τη σχετική στατιστική ανάλυση προέκυψε ότι η επαγγελματική ικανοποίηση αποτελεί τον κύριο προβλεπτικό παράγοντα της αφοσίωσης των εκπαιδευτικών ειδικής αγωγής στο σχολείο που υπηρετούν, ενώ στο μοντέλο πρόβλεψης προσθέτουν σημαντικά τόσο η υποστηρικτική ηγετική συμπεριφορά του διευθυντή του σχολείου όσο και η απουσία αρνητικού συναισθήματος στο χώρο εργασίας.

Ο σκοπός της παρούσας έρευνας αποτελεί η μελέτη του επιπέδου της αριθμητικής ικανότητας παιδιού τυπικής ανάπτυξης προσχολικής ηλικίας. Για τις ανάγκες διερεύνησης του παραπάνω σκοπού χρησιμοποιήθηκε ποιοτική προσέγγιση. Πιο συγκεκριμένα, πραγματοποιήθηκε μελέτη περίπτωσης σε παιδί προσχολικής ηλικίας τυπικής ανάπτυξης μέσω της χορήγησης μιας σειράς δοκιμασιών από το Κριτήριο Λογικομαθηματικής Σκέψης : LogMath (Δεληκανάκη,2007). Ακόμα, χρησιμοποιήθηκε η μεθοδολογική τεχνική της μη δομημένης παρατήρησης του παιδιού κατά τη διάρκεια χορήγησης του κριτηρίου για την καταγραφή του χρόνου απόκρισης του μαθητή, την εκδήλωση στρατηγικών αποφυγής, καθώς και την αμεσότητα των απαντήσεων. Επιπλέον, χρησιμοποιήθηκε η μεθοδολογική τεχνική της ημι-δομημένης συνέντευξης σε έναν εκ των γονέων του υπό μελέτη παιδιού για την σκιαγράφηση του προφίλ του καθώς και στην νηπιαγωγό του να γίνει διασταύρωση των στοιχείων που συλλέχθηκαν από τη χορήγηση των δοκιμασιών που σχετίζονται με την Αριθμητική Ικανότητα του παιδιού. Ο συνδυασμός των μεθοδολογικών τεχνικών επέτρεψε την υλοποίηση μεθοδολογικής τριγωνοποίησης, έτσι ώστε να ερευνηθεί πολύπλευρα το ζήτημα και να προκύψουν αξιόπιστα και έγκυρα ευρήματα. Όσον αφορά στα αποτελέσματα που προέκυψαν από την ποιοτική μέθοδο, το παιδί ανταποκρίθηκε σε μεγάλο ποσοστό στο να απαριθμεί αριθμούς από το 1 έως 13. Επίσης, σημειώθηκε δυσκολία στη δραστηριότητα που αφορούσε τη διατήρηση του πλήθους ύστερα από την χωροταξική διάταξη. Ακόμη ήταν σε θέση να αναγνωρίζει όλα τα αριθμητικά σύμβολα από το 1 έως το 10. Τέλος, το επίπεδο της ικανότητας επίλυσης αριθμητικών προφορικών προβλημάτων πρόσθεσης ή αφαίρεσης αξιολογήθηκε ως αρκετά καλό με δυσκολίες να σημειώνονται μόνο στα πιο σύνθετα προβλήματα.

Σχετικά με τη χαρισματικότητα έχουν δοθεί ποικίλοι ορισμοί, κάποιοι από τους οποίους εστιάζουν στη δεινότητα και στο ταλέντο, άλλοι στο υψηλό IQ, και άλλοι στις εξαιρετικές επιδόσεις. Σκοπός της μελέτης είναι να διερευνήσει τις απόψεις των εκπαιδευτικών σχετικά με τα χαρακτηριστικά/ανάγκες των χαρισματικών μαθητών, τις στάσεις αναφορικά με τις ενστάσεις ως προς τις παροχές προς τους χαρισματικούς μαθητές και την πιθανή συσχέτιση προϋπηρεσίας /θέσης με τις απόψεις αυτές. Η έρευνα έγινε σε εκπαιδευτικούς πρωτοβάθμιας και δευτεροβάθμιας εκπαίδευσης της Γ’ Αθήνας (Ν=278), μέσω δομημένου ηλεκτρονικού ερωτηματολογίου. Τα αποτελέσματα έδειξαν ότι οι εκπαιδευτικοί συνδέουν την έννοια της χαρισματικότητας κυρίως με τα χαρακτηριστικά α) της γρήγορης/ευέλικτης σκέψης, β) του γρήγορου ρυθμού και μεγαλύτερου βάθους μάθησης, γ) την υψηλή απόδοση, δ) την αυξημένη παρατηρητικότητα και ε) τις εξαιρετικές ικανότητες επίλυσης προβλημάτων. Εκφράζουν την άποψη ότι οι χαρισματικοί μαθητές χρειάζονται ιδιαίτερη προσοχή, και παρόλο που συμφωνούν ότι τα παιδιά με μαθησιακές δυσκολίες έχουν μεγαλύτερη ανάγκη ειδικών εκπαιδευτικών υπηρεσιών, δεν συμφωνούν ιδιαίτερα με τις ενστάσεις ως προς τις παροχές προς τους χαρισματικούς μαθητές. Η θέση εργασίας των συμμετεχόντων δεν μεταβάλλει τις απόψεις τους, ενώ ο χρόνος προϋπηρεσίας σχετίζεται με τις απόψεις για την ανάγκη ειδικής προσοχής και προσαρμοσμένων εκπαιδευτικών υπηρεσιών για τους χαρισματικούς μαθητές.

Background: DNA methylation reflects health-related environmental exposures and genetic risk, providing insights into aetiological mechanisms and potentially predicting disease onset, progression and treatment response. An increasingly recognised need for large-scale, longitudinally-profiled samples collected world-wide has made the development of efficient and straightforward sample collection and storage procedures a pressing issue. An alternative to the low-temperature storage of EDTA tubes of venous blood samples, which are frequently the source of the DNA used in such studies, is to collect and store at room temperature blood samples using purpose built filter paper, such as Whatman FTA® cards. Our goal was to determine whether DNA stored in this manner can be used to generate DNA methylation profiles comparable to those generated using blood samples frozen in EDTA tubes. Methods: DNA methylation profiles were obtained from matched EDTA tube and Whatman FTA® card whole-blood samples from 62 Generation Scotland: Scottish Family Health Study participants using the Infinium HumanMethylation450 BeadChip. Multiple quality control procedures were implemented, the relationship between the two sample types assessed, and epigenome-wide association studies (EWASs) performed for smoking status, age and the interaction between these variables and sample storage method. Results: Dried blood spot (DBS) DNA methylation profiles were of good quality and DNA methylation profiles from matched DBS and EDTA tube samples were highly correlated (mean r = 0.991) and could distinguish between participants. EWASs replicated established associations for smoking and age, with no evidence for moderation by storage method. Conclusions: Our results support the use of Whatman FTA® cards for collecting and storing blood samples for DNA methylation profiling. This approach is likely to be particularly beneficial for large-scale studies and those carried out in areas where freezer access is limited. Furthermore, our results will inform consideration of the use of newborn heel prick DBSs for research use.

Objective: To assess the efficacy, safety and acceptability of a new TLC-NOSF dressing with poly-absorbent fibres in the management of exuding leg ulcers, at the different stages of healing. Method: This work presents the results of two prospective, multicentric clinical studies: NEREIDES and CASSIOPEE. Patients with a non-infected, moderate-to-strongly exudating leg ulcer of venous or mixed origin, were treated with the dressing and an appropriate compression system for 12 weeks. The wounds included in NEREIDES had to be in debridement stage, and those in CASSIOPEE at granulation stage. In both studies, the primary outcome was the relative wound area reduction (RWAR) at week 12. Main secondary outcomes included healing rate, time-to-reach wound closure, adverse events and acceptability of the dressing by patients and health professionals. Results: There were 37 patients included in NEREIDES and 51 in CASSIOPEE. The two cohorts presented similar patient and wound characteristics, except from the percentage of sloughy tissue on wound bed at baseline (median: 75% NEREIDES and 30% CASSIOPEE). At week 12, the RWAR (60% NEREIDES and 81% CASSIOPEE), wound closure rates (18% NEREIDES and 20% CASSIOPEE) and mean times-to-reach wound closure (58±27 days NEREIDES and 55±23 days CASSIOPEE) supported the beneficial outcomes of the treatment in both cohorts. In patients with a wound duration ≤6 months, the wound area reduction reached 85% in NEREIDES and 81% in CASSIOPEE, highlighting the importance to initiate adequate treatment as soon as possible. The nature and frequency of the local adverse events were similar in both studies and consistent with the good safety profiles of the poly-absorbent fibres and of the TLC-NOSF dressings. The acceptability of the dressing (easy to apply, conformable and non-adherent to the wound bed at removal, with no pain or bleeding at removal) has been judged ‘very good’ or ‘good’ at each stage of the healing process, by both nursing staff and patients. Conclusion: These clinical results establish the new TLC-NOSF dressing with poly-absorbent fibres (UrgoStart Plus, Laboratoires Urgo) as an effective, safe and simple treatment for the local management of leg ulcers, at the different stages of healing and until wound closure.

Published: March 2019

Objective To achieve international consensus relating to clinical indicators for a chronic wound, wound infection and biofilm presence to inform the development of international clinical guidance for assessing and managing wound infection. Method An online Delphi consensus process of international key opinion leaders in infection was undertaken. A literature search underpinned the development of issue statements related to terminology, emerging topics and debate in the field of wound infection. Experts participated in three rounds of consensus voting, sharing their opinions and indicating their level of agreement with the issue statements. Votes were calculated using web-based software that implements a nominal group voting methodology previously published by Research and Development/University of California at Los Angeles. Results A total of 14 experts took part in the development process. Consensus was reached on clinical indicators of wound chronicity, wound infection and biofilm presence. Agreement was also reached that the term ‘critical colonisation’ should no longer be used to refer to a stage in the wound infection continuum. Conclusion Outcomes from the consensus process were used to inform the development of international, evidence-informed guidance on the assessment and treatment of wound infection to promote improved outcomes for people with wounds.
Lectio Divina and meditation: Exploring identity through contemplative practices
Authors: Dalton Jane E. 
Published: March 2019

Abstract
Engaging in contemplative practices, such as breath and body awareness, meditation, silence and the arts, allows for engagement in the deep work of identity construction to uncover ‘the self who teaches’ (Palmer 1998: 7). Through Lectio Divina, an ancient Benedictine practice, the work of identity construction is deepened through examination of the way in which words and imagery strengthen and support the inner life of the teacher. Researching and engaging in contemplative inquiry and practices, as well as teaching these practices to pre-service teachers, weaves together a tapestry of my identities as an artist–teacher–researcher. These practices support embodied experiences of deep-thought and reflection that includes the cognitive, the affective and the spiritual.
Perancangan dan Pembuatan Data Logger Sederhana untuk Dinamometer Sasis Sepeda Motor
Authors: Sinaga Nazaruddin 
Published: March 2019

Sepeda motor merupakan salah satu alat transportasi utama yang jumlahnya sangat banyak di Indonesia, sehingga memicu munculnya banyak bengkel. Untuk melakukan pengukuran kinerja sepeda motor dengan tepat dibutuhkan dinamometer. Tujuan penelitian ini adalah membuat sebuah data logger sederhana yang dapat digunakan pada dinamometer sasis sepeda motor jenis inersia dan absorbsi. Data logger yang dibuat menggunakan modul data akuisisi NI-DAC USB 6212, dan pemrograman sistem pengukuran menggunakan perangkat lunak LabVIEW. Dari penelitian ini telah berhasil dibuat sebuah data logger untuk pengujian kinerja sepeda motor yang dapat mengukur kecepatan putar mesin dan roda sepeda motor, torsi, daya, dan temperatur, dengan menggunakan sensor induktive pickup, proximity sensor, load cell, dan termometer. Perbandingan hasil uji torsi dan daya, antara data logger yang dibuat dengan nilai spesifikasi yang dikeluarkan oleh pabrik pembuat sepeda motor, menunjukkan perbedaan yang kecil. Dari hasil uji didapatkan bahwa ketidakpastian alat ukur yang dibuat ini memiliki ketidakpastian pengukuran torsi sebesar UTe = ± 2,15% dan ketidakpastian pengukuran daya UPe = ± 2,05%, jika digunakan pada dinamometer absorbsi. Pada dinamometer inersia, ketidakpastian pengukuran torsi adalah sebesar UTe = ± 1,61%, dan ketidakpastian pengukuran daya UPe = ± 1,76%. Hasil penelitian ini jika dikembangkan dengan memanfaatkan DAQ yang lebih murah tentu dapat berkontribusi untuk menurunkan harga dinamometer secara keseluruhan.
Mosaic trisomy 15 and prenatal genetic counselling: a case of Prader-Willi syndrome due to maternal uniparental disomy

Published: March 2019

Abstract

Background
Chromosome abnormalities are a frequent finding in prenatal invasive testing for fetal malformations and/or growth retardation.

Case presentation
We present a case of low level (8%) mosaic trisomy 15 detected on amniocentesis after fetal heart anomalies and IUGR (intrauterine growth retardation) were found on routine scan. Postnatal karyotype confirmed a very low level (2%) mosaicism in the skin but not in blood lymphocytes or in the urine. Methylation specific testing of chromosome 15 showed maternal uniparental disomy and consequently the newborn was diagnosed with Prader-Willi syndrome (PWS).

Conclusions
This case illustrates the need of further genetic testing in all trisomy 15 mosaicisms detected in prenatal invasive testing in order to screen for PWS, a more frequent entity than trisomy 15, altogether providing appropriate genetic counseling and adequate clinical management. The recommendation is applicable to prenatally detected mosaic trisomies of other chromosomes carrying imprinted genes, such as 7, 11 and 14.

Abstract

Background
Irisin and fibroblast growth factor 1 (FGF1) are intricately involved in metabolic syndrome (MetS) and prediabetes (preDM) pathophysiology. This study aimed to compare and correlate irisin and FGF1 plasma levels, adiposity, atherogenicity and hematological indices in 29 normoglycemic MetS and 30 newly diagnosed drug naive prediabetic (PreDM) MetS patients vs. 29 lean and normoglycemic controls.

Materials and methods
Irisin and FGF1 plasma levels were measured using colorimetric assays. Intergroup comparisons were conducted by analysis of variance (ANOVA). Spearman’s rank correlation was also examined.

Results
The mean circulating irisin levels (ng/mL) were significantly higher in the normoglycemic (but not prediabetic) MetS group (p < 0.01), while the mean circulating FGF1 levels (pg/mL) were markedly lower in the prediabetic (but not normoglycemic) MetS group (p < 0.05). Of note unlike FGF1, irisin in the MetS (both normoglycemic and prediabetic;N=59) groups correlated significantly and positively with each of waist circumference (WC), hip circumference (HC), body mass index (BMI), body adiposity index (BAI) and high-density lipoprotein-cholesterol (HDL-C) but not the non-HDL-C. Distinctively MetS-irisin negatively associated with the non-HDL-C/HDL-C ratio, total cholesterol (TC)/HDL-C ratio and the low-density lipoprotein-cholesterol (LDL-C)/HDL-C ratio, but positively with the red cell distribution width (RDW). In the same pool of 59 MetS reruits; Neither biomarker had a relationship with the visceral adiposity index (VAI), the lipid accumulation product (LAP), the conicity index (CI), the waist-hip ratio (WHR), the waist-to-height ratio (WHtR), the blood ratios or the atherogenicity index of plasma (AIP).

Conclusions
As any potential molecular crosstalk of irisin and FGF1 in MetS or its related dysregularities cannot be ruled out; Conversely the utility of irisin and FGF1 as surrogate prognostic biomarkers and putative pharmacotherapeutic targets in the predtion/prevention/management of diabetes and MetS is strongly suggested.

Published: March 2019

Abstract
New results about the growth kinetics of CoB–Co2B layers developed at the surface of CoCrMo alloy using the powder-pack boriding process assisted by a direct current field (PBDCF) were estimated in this work. The PBDCF was conducted at temperatures of 1048 – 1148 K with different exposure times for each temperature, whereas the growth kinetics of the cobalt boride layers was modelled using a system of two differential equations. In addition, indentation properties such as hardness, Young’s modulus and residual stresses were estimated along the depth of the borided CoCrMo surface. The growth kinetics of the cobalt boride layers developed by PBDCF indicated that thicker boride layers were formed on the material’s surface which was in contact to the current field at the anode, in contrast to the surface exposed at the cathode. The kinetics of cobalt boride layers were compared with those obtained by conventional powder-pack boriding process.
A Constitutive Equation for Predicting Elevated Temperature Flow Behavior of BFe10-1-2 Cupronickel Alloy through Double Multiple Nonlinear Regression
Authors: Cai Jun , Wang Meng , Shi Jiamin , Wang Kuaishe , Wang Wen 
Published: March 2019

Abstract
Constitutive analysis for elevated temperature flow behavior of BFe10-1-2 alloy was carried out by using experimental stress–strain data from isothermal hot compression tests on a Gleeble-3800 thermo-mechanical simulator, in a wide of temperature range of 1,023–1,273 K, and strain rate range of 0.001–10 s−1. A constitutive equation based on double multiple nonlinear regression (DMNR) was proposed considering the independent effects of strain, strain rate, temperature and their interrelation. The predicted flow stress data obtained from the developed equation based on DMNR was compared with the experimental data. Correlation coefficient (R), average absolute relative error (AARE) and relative errors were introduced to verify the validity of the developed constitutive equation. The results showed that the developed constitutive equation based on DMNR could predict flow stress of BFe10-1-2 alloy with good correlation and generalization.
Lightbeam Configuration Method and Interference Elimination Resource Scheduling for Indoor Multibeam VLC Networks
Authors: Tran Cong-Nam , Nguyen Nam-Hoang , Hoang Trong-Minh 
Published: March 2019

Abstract
Visible light communications (VLC) is considered as an alternative communications technology for providing indoor wireless services. VLC systems are expected to offer high data transmission rate and seamless coverage. In order to achieve these requirements, VLC systems utilizing multi-lightbeam access points (multibeam VLC-AP) for downlink transmission have been proposed recently. In this paper, we present a lightbeam configuration method and an interference elimination resource scheduling mechanism (IERS) for indoor multibeam multi-access point VLC systems. The proposed lightbeam configuration method ensures seamless connectivity between user equipment and VLC-AP. The proposed IERS mechanism consists of a beam assignment algorithm and a resource allocation algorithm for eliminating co-channel interference as well as improving system performance. Performance results obtained by computer simulation indicate that there are significant improvements in terms of downlink signal to interference plus noise ratio, user throughput and packet delay when the proposed IERS mechanism is deployed.
