Η επέλαση του νέου κορωνοϊού Covid-19 και οι επιπτώσεις της πανδημίας σε διεθνές επίπεδο διαμορφώνουν ένα πρωτόγνωρο σκηνικό για τους πολίτες αλλά και τις οργανωμένες κοινωνίες. Τα εκπαιδευτικά συστήματα σε διεθνές επίπεδο κλήθηκαν να σηκώσουν σε ελάχιστο χρόνο την ευθύνη της μετάβασης σε ένα νέο περιβάλλον υποστήριξης της μάθησης στο σπίτι σε κατάσταση έκτακτης ανάγκης.Η εργασία διαρθρώνεται σε δύο κύρια μέρη. Στο πρώτο μέρος, το ενδιαφέρον εστιάζεται σε μια πρώτη καταγραφή των ενεργειών με βάση τις οποίες τα εκπαιδευτικά συστήματα τόσο διεθνώς όσο και στην Ελλάδα επιχειρούν να αντιμετωπίσουν τις επιπτώσεις της πανδημίας. Στο δεύτερο μέρος, διατυπώνεται ο ισχυρισμός ότι το νέο εκπαιδευτικό περιβάλλον που αναδύεται δεν θα πρέπει να περιοριστεί στον υποστηρικτικό του ρόλο στο πλαίσιο των έκτακτων συνθηκών που βιώνουμε, αλλά οφείλει να προετοιμάσει τη μετάβαση «στο Ανοιχτό Σχολείο της Διερευνητικής Μάθησης, της Συνεργατικής Δημιουργικότητας και της Κοινωνικής Αλληλεγγύης». Ένα σχέδιο τριών φάσεων προτείνεται προς αυτή την κατεύθυνσή.

Οι δύο τελευταίες σχολικές χρονιές έδωσαν στην εξ αποστάσεως σχολική εκπαίδευση αναπάντεχα τον πρωταγωνιστικό ρόλο, διεθνώς, λόγω της εξάπλωσης της πανδημίας COVID-19 και των συνεπαγόμενων εκτάκτων συνθηκών. Σε πολλές χώρες ξεκίνησε η «επείγουσα εξ αποστάσεως σχολική εκπαίδευση», όρος που πρωτοεμφανίστηκε το 2020, για να αντιμετωπιστεί η πρωτόγνωρη κατάσταση με μεθόδους απομακρυσμένης διδασκαλίας («Επείγουσα Απομακρυσμένη Διδασκαλία» -“Emergency Remote Teaching”).Ένα τέτοιο μεγάλο εγχείρημα, χωρίς προηγούμενο, ξεκίνησε και στη χώρα μας με το αναγκαστικό κλείσιμο των σχολείων τον Μάρτιο του 2020.Οι νέες σύνθετες πρωτόγνωρες συνθήκες απαιτούν νέους ρόλους για όλους τους εμπλεκόμενους φορείς της σχολικής εκπαίδευσης. Τα εκπαιδευτικά συστήματα δοκιμάζονται στους τρόπους και τις μεθόδους αναζητώντας τη διατήρησης της εκπαιδευτικής πράξης, την παιδαγωγική ευθύνη, τη βελτίωση του ψηφιακού γραμματισμού και την τεχνολογική ετοιμότητα.Η εκπαιδευτική κοινότητα περιμένει από το Υπουργείο Παιδείας μια πιο συντονισμένη στρατηγική βασισμένη πάνω σε θέματα παιδαγωγικού σχεδιασμού και όχι απλά αναφορές σε τεχνολογικό εξοπλισμό και προγράμματα. Τώρα είναι η κατάλληλη στιγμή για να αποφασίσει η πολιτική ηγεσία τη δημιουργία ενός ευέλικτου φορέα για τον συντονισμό της εξ αποστάσεως εκπαίδευσης στην πρωτοβάθμια και δευτεροβάθμια εκπαίδευση.

Η εκπαίδευση και κατάρτιση στα δημοσία Ι.Ε.Κ, πραγματοποιείται με τη φυσική παρουσία των καταρτιζομένων. Η εμπειρία της διαδικτυακής διδασκαλίας από το Μάρτιο του 2020 μέχρι και τον Ιούνιο του 2021, ήταν πρωτοφανής. Η παρούσα μελέτη επιχειρεί να παρουσιάσει δεδομένα για τη διεξαγωγή της Εξ Αποστάσεως Εκπαίδευσης (εφεξής ΕξαΕ) στις συγκεκριμένες δομές εκπαίδευσης. Στόχος της, μέσα από ποσοτική έρευνα, είναι η διερεύνηση των απόψεων των καταρτιζομένων στην περίοδο της εξ αποστάσεως εκπαίδευσης λόγω της πανδημίας Covid-19. Τα δεδομένα συλλέχθηκαν με τη βοήθεια κατάλληλα διαμορφωμένου ηλεκτρονικού ερωτηματολογίου. Το δείγμα της μελέτης αποτέλεσαν 257 καταρτιζόμενοι/ες, από τα έξι δημόσια Ι.Ε.Κ. της Δ. Μακεδονίας. Τα ευρήματα αναδεικνύουν ότι η άποψη των καταρτιζομένων είναι αρνητική έως μέτρια, καθώς θεωρούν ότι η «εξ ανάγκης αυτή εκπαίδευση», δεν ήταν το ίδιο οργανωμένη και αποτελεσματική όσο η δια ζώσης. Ειδικότερα οι απόψεις διαφοροποιούνται σε σχέση με τις ειδικότητες κατάρτισης. Ως εκ τούτου, οι καταρτιζόμενοι/ες δήλωσαν την προτίμησή τους στη φυσική παρουσία, ενώ η πρακτική άσκηση ήταν το στοιχείο που τους έλειπε περισσότερο στην περίοδο της εξ αποστάσεως εκπαίδευσης.

Introduction
Deprescribing fall-risk increasing drugs (FRIDs) is promising for reducing the risk of falling in older adults. Applying appropriate deprescribing in practice can be difficult due to the outcome uncertainties associated with stopping FRIDs. The ADFICE_IT intervention addresses this complexity with a clinical decision support system (CDSS) that facilitates optimum deprescribing of FRIDs by using a fall-risk prediction model, aggregation of deprescribing guidelines, and joint medication management.

Methods
The development process of the CDSS is described in this paper. Development followed a user-centered design approach in which users and experts were involved throughout each phase. In phase I, a prototype of the CDSS was developed which involved a literature and systematic review, European survey (n = 581), and semi-structured interviews with clinicians (n = 19), as well as the aggregation and testing of deprescribing guidelines and the development of the fall-risk prediction model. In phase II, the feasibility of the CDSS was tested by means of two usability testing rounds with users (n = 11).

Results
The final CDSS consists of five web pages. A connection between the Electronic Health Record allows for the retrieval of patient data into the CDSS. Key design requirements for the CDSS include easy-to-use features for fast-paced clinical environments, actionable deprescribing recommendations, information transparency, and visualization of the patient’s fall-risk estimation. Key elements for the software include a modular architecture, open source, and good security.

Conclusion
The ADFICE_IT CDSS supports physicians in deprescribing FRIDs optimally to prevent falls in older patients. Due to continuous user and expert involvement, each new feedback round led to an improved version of the system. Currently, a cluster-randomized controlled trial with process evaluation at hospitals in the Netherlands is being conducted to test the effect of the CDSS on falls. The trial is registered with ClinicalTrials.gov (date; 7-7-2022, identifier: NCT05449470).

Objective
This study aims to examine the validity of the MFS by analyzing the electronic medical records on fall risk in obstetrics and gynecology wards and determine the optimal cut-off score of the Morse Fall Scale.

Design
A retrospective survey.

Methods
The research was conducted in an Obstetrics and Gynecology Hospital and a general hospital. The sample included 136 fall inpatients and 120 no-fall inpatients recruited from January 1st, 2020, to July 10th, 2022. The Morse Fall Scale was analyzed using the gold standard of patients who fell while hospitalized, assessing the area under the Receiver Operating Characteristic curve, sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and Kappa.

Results
At cut-off scores of 40, 45,50, and 55, the area under the Receiver Operating Characteristic curve was 0.772, 0.761, 0.749, and 0.763, respectively. The Youden index was 0.543, 0.521, 0.498, and 0.525, while Kappa values were 0.540, 0.518, 0.490, and 0.515. Sensitivity was 0.735, 0.713, 0.640, and 0.625; specificity was 0.808, 0.808, 0.858, and 0.900. The positive predictive values were 0.813, 0.808, 0.837, and 0.876, and the negative predictive values were 0.729, 0.713, 0.678, and 0.679. Accuracy were 0.770, 0.758, 0.742, and 0.754.

Conclusions
The Morse Fall Scale demonstrates good predictive performance for assessing fall risk in gynecology and obstetrics wards. The optimal cut-off score is 40.
Incidence of straight and angulated screw channel following immediate implant placement in esthetic zone: A simulated cone-beam computed tomography study
Authors: Radomsutthisarn Watcharapon , Kretapirom Kornkamol , Nakaparksin Pranai 
Published: September 2024

Statement of problem
The demand for immediate implant placement (IIP) in the esthetic zone is rapidly increasing. Despite the treatment’s benefits, the sagittal root position often dictates implant angulation, commonly necessitating the use of cement-retained restorations. This study investigates the impact of angulated screw channel on IIP in the esthetic zone.

Purpose
The purpose of this cone-beam computed tomography (CBCT) study was to determine the probability of IIP in the esthetic zone, using four different implant angulations.

Materials and methods
A retrospective review of CBCT images was conducted and accessed on 9 June 2021. The midsagittal images of maxillary anterior teeth were input into an implant planning software (Implant Studio®). Bone Level X Straumann® implant (BLX 3.5, 3.75, 4.0, 4.5, 5.0 mm) and Bone Level Tapered implant (BLT 2.9, 3.3 mm) were selected for 3D implant planning of IIP in the esthetic zone. The frequency distribution and probability of IIP were recorded and compared among all maxillary anterior teeth.

Results
CBCT images from 720 teeth (120 patient) were evaluated, revealing an overall probability of IIP in the esthetic zone is 76.11% (548/720). Different implant restoration type was evaluated in this study, with the following results; straight screw-retained prosthesis at 3.47% (19/548), cement-retained prosthesis at 14.59% (80/548) and angle screw-retained prosthesis at 85.40% (468/548).

Conclusion
IIP with traditional straight screw-retained prosthesis demonstrated the lowest probability. Nevertheless, the use of angulated screw channels enhances the probability of achieving straight screw-retained prostheses.

Clinical implications
The angulated screw channel is essential for increasing the probability of screw-retained prosthesis in IIP in the esthetic zone. However, limitation in screw angle correction still necessitate the use of cement-retained prostheses for numbers of patients undergoing IIP.
Prevalence of pregnancy termination and associated factors among married women in Papua New Guinea: A nationally representative cross-sectional survey
Authors: Maviso McKenzie , Aines Paula Zebedee , Potjepat Gracelyn , Geregl Nancy , Mola Glen , Bolnga John W. 
Published: September 2024

Background
Pregnancy termination or induced abortion is not decriminalized, and access to safe abortion services is largely unavailable in Papua New Guinea (PNG). However, the practice is common throughout the country. This study aimed to estimate the prevalence and determine factors associated with pregnancy termination among married women aged 15–49 years in PNG.

Methods
Secondary data from the 2016–2018 PNG Demographic and Health Survey (PNGDHS) was used. A total weighted sample of 6,288 married women were included. The Complex Sample Analysis method was used to account for the cluster design and sample weight of the study. Chi-square tests and multivariable logistic regression were used to assess factors associated with pregnancy termination. Adjusted odds ratios (aORs) with 95% Confidence Intervals (CIs) were reported.

Results
The prevalence of pregnancy termination was 5.3%. Nearly half (45.2%) of all pregnancy terminations occurred in the Highlands region. Women aged 35–44 years (aOR = 8.54; 95% CI: 1.61–45.26), not working (aOR = 6.17; 95% CI: 2.26–16.85), owned a mobile phone (aOR = 3.77; 95% CI: 1.60–8.84), and lived in urban areas (aOR = 5.66; 95% CI: 1.91–16.81) were more likely to terminate a pregnancy. Women who experienced intimate partner violence (IPV) were 2.27 times (aOR = 2.27; 95% CI: 1.17–4.41) more likely to terminate a pregnancy compared to those who did not experience IPV. Women with unplanned pregnancies were 6.23 times (aOR = 6.23; 95% CI: 2.61–14.87) more likely to terminate a pregnancy. Women who knew about modern contraceptive methods and made independent decisions for contraceptive use were 3.38 and 2.54 times (aOR = 3.38; 95% CI: 1.39–8.18 and aOR = 2.54; 95% CI: 1.18–5.45, respectively) more likely to terminate a pregnancy.

Conclusion
The findings highlight the role of sociodemographic and maternal factors in pregnancy termination among married women in PNG. Efforts aimed at reducing unplanned pregnancies and terminations should focus on comprehensive sexual and reproductive health education and improving easy access to contraceptives for married couples. Post-abortion care should also be integrated into the country’s legal framework and added as an important component of existing sexual and reproductive health services.

A novel autonomous navigation constellation in the Earth–Moon system
Authors: Liu Bin , Li Hengnian , Hou Xiyun , Yang Jie , Huyan Zongbo 
Published: September 2024

Abstract
With more and more activities in cislunar space and deep space, a navigation system that can provide autonomous navigation service for cislunar or even deep space missions has become an urgent need. This article proposes a new type of navigation constellation which is placed on two kinds of special orbits, namely the dynamical substitutes around the triangular libration points and the distant retrograde orbits (DROs). Both types of orbits have the same characteristics of long-term stability under the full force model, so no orbit control is needed and it can operate autonomously without ground support. First, using inter-satellite range data, the autonomous orbit determination between navigation satellites on the dynamical substitutes and the DROs is investigated under the full force model. Then, taking a translunar orbit as an example, the constellation’s navigation performance based on inter-satellite range observation is evaluated. With range errors of 1, 10, and 100 m, respectively, the navigation capability of the constellation is successfully verified in the sense that the accuracy of the determined orbit reaches the level of the observation data. From the viewpoint of stable autonomous navigation, the current results are meaningful and deserve further consideration when deploying the navigation constellation in the Earth–Moon system.

Published: September 2024

Abstract
Dried lemongrass (DLG) herb is high in total phenolic compounds (1,388 mg gallic acid equivalent/100 g), antioxidant scavenging activity (57.88%), and dietary fibers (19.61%), and it also imparts lemon flavor, minerals, and several health benefits. Therefore, it is considered a cost-effective and functional ingredient for various food systems. A trial was conducted to incorporate DLG into a functional low-fat lemon frozen dessert as a fat mimetic and to assess its impacts on physicochemical, rheological, total phenolic compounds, antioxidant scavenging activity, sensory properties, and production costs. A control full-fat frozen dairy dessert (FFD) with 6% fat was prepared for comparison. DLG was added to a low-fat frozen dessert (LFD) with 1% fat at ratios of 0, 0.5, 1.0, and 1.5%. Results showed that FFD had higher rheological characteristics, melting resistance, production costs, and sensory properties compared to LFD. The use of DLG increased mix specific gravity, freezing point depression, apparent viscosity, consistency coefficient index, overrun, total phenolic compounds, and antioxidant scavenging activity while decreasing the pH value compared to LFD. Adding 0.5–1.0% DLG to LFD significantly improved overall acceptability and reduced production costs by 23.80 and 18.56%, respectively. The functional LFD with 0.5–1% DLG achieved comparable quality characteristics to the full-fat treatment.
A corpus-based study on semantic and cognitive features of bei sentences in Mandarin Chinese
Authors: Xie Yonghui , Niu Ruochen , Liu Haitao 
Published: September 2024

Abstract

Bei sentences in Mandarin Chinese with SOV word order have attracted extensive interest. However, their semantic features lacked quantitative evidence and their cognitive features received insufficient attention. Therefore, the current study aims to quantitatively investigate the semantic and cognitive features through the analysis of nine annotated factors in a corpus. The results regarding bei sentences show that (i) subjects exhibit a tendency to be definite and animate; non-adversative verbs have gained popularity over time, and intransitive verbs are capable of taking objects; (ii) subject relations tend to be long, implying heavy cognitive load, whereas the dependencies governed by subjects are often short, suggesting light cognitive load; and (iii) certain semantic factors significantly impact cognitive factors; for instance, animate subjects tend to govern shorter dependencies. Overall, our study provides empirical support for the semantic features of bei sentences and reveals their cognitive features using dependency distance.
The red dress is cute: why subjective adjectives are more often predicative
Authors: Glass Lelia 
Published: September 2024

Abstract
Which adjectives tend to occur as attributive (the cute/red dress) versus predicative (the dress is cute/red) and why? Building on findings from Wiegand et al. (2013. Predicative adjectives: An unsupervised criterion to extract subjective adjectives. In Lucy Vanderwende, Hal DauméIII & Katrin Kirchhoff (eds.), Proceedings of the 2013 conference of the North American chapter of the
Association for Computational Linguistics
: Human language technologies (NAACL-HLT), 534–539. Atlanta, GA: Association for Computational Linguistics) and Vartiainen (2013. Subjectivity, indefiniteness and semantic change. English Language and Linguistics 17(1). 157–179), this paper argues that subjective adjectives such as cute tend to be placed in predicative position not just because they often describe discourse-new information, but because this position serves to foreground information that the hearer may disagree with. This claim is supported using data from the Corpus of Contemporary American English (Davies, Mark. 2008. The corpus of contemporary American English: One billion words, 1990-present. Available at: https://www.english-corpora.org/coca/) combined with human annotations for subjectivity from Scontras et al. (2017. Subjectivity predicts adjective ordering preferences. Open Mind 1(1). 53–66) et seq.; and data from image captions versus descriptions (for seeing versus low-vision people) from the National Gallery of Art. A production experiment manipulates the discourse context to further show that adjectives tend to be placed in predicative position when they express controversial information. Overall, this paper explores how the lexical semantics of adjectives shapes the pragmatic contexts in which they tend to be used, which in turn shapes the syntax of the sentences using them.
Effect of tannic acid chelating treatment on thermo-oxidative aging property of natural rubber
Authors: Wei Chuanyu , Zheng Tingting , Luo Yuhang , Yang Changjin , Wei Yanchan , Liao Shuangquan 
Published: September 2024

Abstract
Metal ions are crucial in the production and preservation of fresh natural rubber latex. However, they also catalyze the thermo-oxidative aging of rubber products, leading to premature product degradation. This study investigates the use of tannic acid (TA) to chelate metal ions, thereby enhancing the thermo-oxidative aging resistance of natural rubber (NR). The findings indicate that NR treated with a 1.5 g·L−1 TA solution exhibits superior tensile strength, elongation at break, and crosslink density post-thermo-oxidative aging compared to untreated samples. Analysis of ultraviolet–visible absorption spectra, Fourier transform infrared spectra, and X-ray photoelectron spectroscopy confirms that TA’s resistance to thermo-oxidative aging stems from its ability to form stable chelates with metal ions, reducing their catalytic activity and mitigating oxidative degradation. Consequently, TA chelation treatment is proposed as an effective method to enhance the thermo-oxidative aging resistance of NR.
Integrating optical communication in MIMO-OTFS using hybrid signal detection methods: analyzing the throughput and spectrum

Published: September 2024

Abstract
MIMO-OTFS (multiple input multiple output in orthogonal time-frequency space) modulation is a key component of sophisticated optical radio systems, helping to increase their speed and range. The increased capacity of optical communication can be put to use in a number of applications. In order to minimize latency, we optimize the bit error rate (BER) and power spectral density (PSD) of the framework by applying the hybrid signal detection technique known as zero forcing equalizer and minimal mean square error (ZFE + MMSE) to the MIMO-optical OTFS system (16 × 16, 64 × 64, and 256 × 256) in this article. The suggested ZFE + MMSE works better than the traditional signal detection algorithms, according to the work’s experimental study. Furthermore, without using any detection techniques, the MIMO-OTFS outperforms the MIMO-OFDM by attaining an SNR gain of 1.2–2.3 dB.
