Published: October 2023

In France, the annual volume of dredged sediments is significantly increasing, which has become a real environmental problem. Nevertheless, these sediments can be used beneficially as supplementary cementing material. On the other hand, external sulfate attack is one of the most aggressive causes of deterioration that affects the durability of concrete structures. This study focused on the valorization of river-dredged sediments from Noyelles-Sous-Lens (Hauts-de-France) as a mineral addition in substitution of Portland cement, and it studied their impacts on the mechanical behavior and durability of reinforced mortars. X-ray diffraction (XRD) analysis indicated the presence of clay minerals in the raw sediment. In order to activate this clay fraction, flash calcination was applied at a temperature of 750 °C. In addition, four mixed mortars were formulated by mixing a Portland cement (CEM I 52.5 N) and the calcined sediments as a partial substitute for cement with proportions of 0%, 15%, 20%, and 30%, then stored in water tanks at room temperature (20 ± 2 °C) for 90 days in order to immerse them in a tank containing a 5% MgSO4 solution and to track the evolution of their corrosion potential as well as their mass variations every 20 days for a period of 360 days. The following additional tests were carried out on these mortars: tests of resistance to compression and flexion and to porosity by mercury intrusion. The results obtained from the majority of these tests showed that the mortar containing 15% calcined sediments is as effective and durable as the reference mortar itself. The main conclusion we can draw from these results is that the presence of these calcined sediments improves the overall behavior of the mortar.
Applying Physics-Informed Neural Networks to Solve Navier–Stokes Equations for Laminar Flow around a Particle
Authors: Hu Beichao , McDaniel Dwayne
Published: October 2023

In recent years, Physics-Informed Neural Networks (PINNs) have drawn great interest among researchers as a tool to solve computational physics problems. Unlike conventional neural networks, which are black-box models that “blindly” establish a correlation between input and output variables using a large quantity of labeled data, PINNs directly embed physical laws (primarily partial differential equations) within the loss function of neural networks. By minimizing the loss function, this approach allows the output variables to automatically satisfy physical equations without the need for labeled data. The Navier–Stokes equation is one of the most classic governing equations in thermal fluid engineering. This study constructs a PINN to solve the Navier–Stokes equations for a 2D incompressible laminar flow problem. Flows passing around a 2D circular particle are chosen as the benchmark case, and an elliptical particle is also examined to enrich the research. The velocity and pressure fields are predicted by the PINNs, and the results are compared with those derived from Computational Fluid Dynamics (CFD). Additionally, the particle drag force coefficient is calculated to quantify the discrepancy in the results of the PINNs as compared to CFD outcomes. The drag coefficient maintained an error within 10% across all test scenarios.

Bacterial resistance to different antimicrobial agents is growing with alarming speed, especially when bacterial cells are living in biofilm. Hybrid nanoparticles, synthesized through the green method, hold promise as a potential solution to this challenge. In this study, 66 actinomycete strains were isolated from three distinct marine sources: marine sediment, the algae Codium bursa, and the marine sponge Chondrosia reniformis. From the entirety of the isolated strains, one strain, S26, identified as Saccharopolyspora erythrea, was selected based on its taxonomic position and significant antimicrobial activity. Using the biomass of the selected marine Actinobacteria, the green synthesis of eco-friendly silver carbonate nanoparticles (BioAg2CO3NPs) is reported for the first time in this pioneering study. The BioAg2CO3NPs were characterized using different spectroscopic and microscopic analyses; the synthesized BioAg2CO3NPs primarily exhibit a triangular shape, with an approximate size of 100 nm. Biological activity evaluation indicated that the BioAg2CO3NPs exhibited good antimicrobial activity against all tested microorganisms and were able to remove 58% of the biofilm formed by the Klebsiella pneumoniae kp6 strain.

Published: October 2023

This paper presents a novel modified electrode for an amperometric hydrazine sensor based on multi-walled carbon nanotubes (MWCNTs) modified with lignosulfonate (LS) and decorated with palladium nanoparticles (NPds). The MWCNT/LS/NPd hybrid was characterized by atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The electrochemical properties of the electrode material were evaluated using cyclic voltammetry and chronoamperometry. The results showed that GC/MWCNT/LS/NPd possesses potent electrocatalytic properties towards the electro-oxidation of hydrazine. The electrode demonstrated exceptional electrocatalytic activity coupled with a considerable sensitivity of 0.166 μA μM−1 cm−2. The response was linear from 3.0 to 100 µM L−1 and 100 to 10,000 µM L−1, and the LOD was quantified to 0.80 µM L−1. The efficacy of the modified electrode as an electrochemical sensor was corroborated in a study of hydrazine determination in water samples.

Coronavirus 2019 (COVID-19) lockdown periods had a significant negative impact on people’s lives and psychological well-being. However, the impact of lockdowns differed between individuals. This study aimed to identify vulnerable groups and investigated the relationship between mood and perceived immune fitness and the number and severity of coronavirus 2019 (COVID-19) symptoms during the first COVID-19 lockdown in the Netherlands. In addition, the impact of emotion regulation and other preventive measures was considered. The aim of the study was to identify possible differences according to sex, age, and the presence of underlying disease. A two-part online survey among N = 1415 individuals of the Dutch population (18 to 94 years old) was conducted in the summer of 2020. N = 541 of these participants also completed part 2 of the survey. A series of questionnaires was completed on mood, quality of life, lifestyle, immune fitness, and the number and severity of COVID-19 symptoms. Retrospectively, the period before the first lockdown (15 January–14 March 2020) was compared with the first lockdown (15 March–11 May 2020). The analysis revealed that the lockdown period was associated with significantly poorer mood, poorer immune fitness, and reduced quality of life. Poorer mood was associated with a significantly reduced immune fitness and a significant increase in the number and severity of COVID-19 symptoms. Mood changes did not differ significantly between men and women. Some mood effects were significantly more pronounced for individuals with underlying diseases (depression, fatigue, and stress) and younger individuals (depression and loneliness). Regarding lifestyle factors, no significant lockdown effects were seen according to underlying disease status. During the lockdown period, women reported a decline in nutrition scores, which was not seen in men, whereas they reported receiving more support from family and friends than men. Regarding age, younger individuals reported a significantly greater negative impact on physical activity and being active than the older participants. No differential effects for the groups were found for health correlates. In conclusion, significant negative lockdown effects on mood, quality of life, and immune fitness were observed across the population. The effects were significantly more pronounced among young individuals and those with underlying disease.
Stress Evaluation Method by Neutron Diffraction for HCP-Structured Magnesium Alloy
Authors: Harjo Stefanus , Gong Wu , Kawasaki Takuro
Published: October 2023

Tensile deformation in situ neutron diffraction of an extruded AZ31 alloy was performed to validate conventional procedures and to develop new procedures for stress evaluation from lattice strains by diffraction measurements of HCP-structured magnesium alloys. Increases in the lattice strains with respect to the applied true stress after yielding largely vary among [hk.l] grains. Some [hk.l] grains have little or no increase in lattice strain, making it difficult to use the conventional procedures to determine the average phase strain by using lattice constants or by averaging several lattice strains. The newly proposed procedure of stress evaluation from the lattice strains shows very high accuracy and reliability by weighting the volume fraction of [hk.l] grains and evaluating them in many [hk.l] orientations in addition to multiplication by the diffraction elastic constant. When multiple hk.l peaks cannot be obtained simultaneously, we recommend to use the 12.1 peak for stress evaluation. The lattice strain value evaluated from the 12.1 peak shows a good linear relationship with the applied true stress for the whole deformation region.

Authors: Wen Chaoran , Nie Ting , Li Mingxuan , Wang Xiaofeng , Huang Liang
Published: October 2023

Under low-illumination conditions, the quality of the images collected by the sensor is significantly impacted, and the images have visual problems such as noise, artifacts, and brightness reduction. Therefore, this paper proposes an effective network based on Retinex for low-illumination image enhancement. Inspired by Retinex theory, images are decomposed into two parts in the decomposition network, and sent to the sub-network for processing. The reconstruction network constructs global and local residual convolution blocks to denoize the reflection component. The enhancement network uses frequency information, combined with attention mechanism and residual density network to enhance contrast and improve the details of the illumination component. A large number of experiments on public datasets show that our method is superior to existing methods in both quantitative and visual aspects.

Published: October 2023

For autonomous vehicles driving in off-road environments, it is crucial to have a sensitive environmental perception ability. However, semantic segmentation in complex scenes remains a challenging task. Most current methods for off-road environments often have the problems of single scene and low accuracy. Therefore, this paper proposes a semantic segmentation network based on LiDAR called Multi-scale Augmentation Point-Cylinder Network (MAPC-Net). The network uses a multi-layer receptive field fusion module to extract features from objects of different scales in off-road environments. Gated feature fusion is used to fuse PointTensor and Cylinder for encoding and decoding. In addition, we use CARLA to build off-road environments for obtaining datasets, and employ linear interpolation to enhance the training data to solve the problem of sample imbalance. Finally, we design experiments to verify the excellent semantic segmentation ability of MAPC-Net in an off-road environment. We also demonstrate the effectiveness of the multi-layer receptive field fusion module and data augmentation.

Diş hekimliğinde dijital teknolojilerin yaygınlaşması ile birlikte hareketli protezlerin bilgisayar destekli üretimi için polimetilmetakrilat (PMMA) ve polietereterketon (PEEK) blok kaide materyalleri kullanılmaktadır. Bu materyallerin su emilimi ve çözünürlük gibi fiziksel özelliklerinin geleneksel yöntemle ısı ile polimerize edilen PMMA’dan daha üstün olduğu öne sürülmektedir. Bu çalışmada, blok PMMA, Titanyum dioksit (TiO2) içerikli PEEK kaide materyallerinin ve PEEK’in veneerlenmesinde kullanılan bir indirekt laboratuvar kompozit rezininin su emilimi ve suda çözünürlük değerlerinin ısı ile polimerize olan PMMA ile karşılaştırılması amaçlanmıştır. Blok PMMA, TiO2 içerikli PEEK, indirekt kompozit rezini ve ısı ile polimerize olan akrilikten 10×2 mm disk şeklinde örnekler hazırlanmıştır (n=40). Örnekler hassas terazide tartıldıktan sonra 7 gün süreyle distile suda 37oC’de saklanmıştır. Daha sonra hassas terazide tartılarak su emilimi oranı hesaplanmıştır. Çözünürlük ise örnekler tamamen kurutulduktan sonra tekrar tartılarak hesaplanmıştır. Su emilimi ve çözünürlük verileri Kruskal-Wallis ve post-hoc Tukey testleri ile analiz edilmiştir (p=0.05). Blok PMMA (%1.372), indirekt kompozit rezine (%0.389) ve PEEK’e (%0.212) göre daha fazla su emilimi gösterirken; ısı ile polimerize olan PMMA örnekler (%1.329) ise PEEK’e göre daha fazla su emilimi göstermiştir (p<0.001). Isı ile polimerize olan PMMA ile blok PMMA ve indirekt kompozit rezin arasında ise su emilimi açısından anlamlı fark görülmemiştir (p>0.05). Isı ile polimerize olan PMMA, en yüksek suda çözünürlüğü göstermiştir. PEEK örnekler blok PMMA’ya (p=0.003) ve ısı ile polimerize olan PMMA’ya (p=0.000) göre daha az suda çözünürlük göstermiştir. İndirekt kompoziti, blok PMMA’ya (p=0,011) ve ısı ile polimerize olan akriliğe göre (p=0.000) daha az çözünürlük göstermiştir. Su emilimi ve çözünürlüğün hareketli protezlerde akrilik kaidenin mekanik özelliklerini, mikroorganizma tutulumunu, renklenmesini olumsuz yönde etkilediği bilinmektedir. Bu çalışmanın sonuçlarına göre TiO2 içerikli PEEK ve yüzeyinin dişeti renginde veneerlenmesinde kullanılan indirekt kompozit rezinin kaide materyali olarak kullanıldığında her iki PMMA materyalden daha az su emilimi ve çözünürlük göstermesi biyolojik, mekanik ve estetik özellikler bakımından uzun vadede hareketli protezler için yarar sağlayabilir.

This full paper is a provides detail of the work in progress but moreover provides a a conceptual analysis of  the methodologies applied to this emerging domain of study. The project is funded by the EU Horizon programme with UK Associate partners funded through UKRI and coordinated by the DIPF, Leibniz Institute for Research and Information in Education, Frankfurt and involves seven partners located across Europe, Serious Games Interactive (SGI) Denmark, Centre for Social Innovation (ZSI) Austria, International University of Rioja (UNIR) Spain, Frederick University, Cyprus, Playmob and The University of Bolton (UoB) as UK associate partners. The project incorporates collaborative design and citizen science methods and brings together researchers with expertise in the areas of games, data analytics, and policy development. This integrated investigation will be articulated by case studies of the use of games in facilitating dialogue between citizens and policy stakeholders including policy makers, policy implementers, political parties, campaigning organisations and affected citizens. This will be achieved by leveraging the central role of games in contemporary culture by combining academic studies with practical experimentation of novel applications of games. The context for the research is the global challenge of climate emergency, and each case study incorporates a research cycle addressing a policy issue and research questions, using multiple pilots to generate both quantitative and qualitative and data to further inform research activity.
Experimenting with GAME OVER to create processes of reflection and academic inquiry
Authors: Jensen Camilla , Dau Susanne
Published: October 2023

Educations are challenged in their effort to facilitate students learning when it comes to especially processes of reflection. Also in a Problem-Based Learning context, errors often cause a lack of motivation, that gives reflection processes and academic inquiry difficult conditions Game-Based Learning is thus suggested as a learning strategy which can address these learning needs though a procedural rhetoric. Furthermore, Game-Based Learning is found to affords students risk taking and engagement in learning activities However, a literature review of empirical studies of Game-Based Learning reveals existing gaps in the literature. There are missing models for how academic activities can be enhanced through the use of Game-Based Learning, here especially the transformation of “Game Over” elements into a learning environment based on physical Game objects. This study aims to describe learning situations where the academic focal point is a reflective and innovative writing process through gaming principles. The study design aims to identify what impact Game-Based Learning have on facilitating academic literacy to create processes of reflection. Based on two cases, the empirical data are retrieved from video observations during a period of 1 year. A qualitative content analysis and interpretation of the collected data reveals how the use of “Game Over” strengthens the depth of the students' writing through a reflective and metacognitive approach to the task. As a contribution to the existing knowledge, this paper presents a Procedural Rhetoric for how to work with a “Game Over” strategy to facilitate academic literacy and thereby create processes of reflection in a physical context.
Teaching with business simulation games: Identifying and overcoming hurdles to adoption.
Authors: Rogmans Tim
Published: October 2023

Although the use of business simulation games (BSG) in higher education has grown steadily, there are still many instructors who have never taught with BSG and their use in several academic disciplines remains very low. Existing research has primarily used quantitative surveys to identify the hurdles that prevent faculty from teaching with BSG. This article uses a focus group methodology to further investigate the obstacles to using BSG and subsequently applies a change management framework to identify levers that can be used to promote the use of BSG. The obstacles to adoption are classified into categories of suitability, risk and resources.

Focus group participants expressed concerns over the suitability of existing BSG for their courses and the expected time required to identify, evaluate and prepare to teach with BSG. These factors made most focus group participants consider teaching with BSG as fraught with risk. In response, universities can encourage faculty to start using BSG in their teaching through the provision of resources, information and training, and through organizational adjustments such as incentives and flexibility to adjust course syllabi. A full range of measures is identified and the environmental contexts in which each one is likely to be effective are discussed. The individual levers that can bring about change have different environmental contexts in which they are likely to be effective.

Real-Time Intelligent Anomaly Detection and Prevention System
Authors: GÜRFİDAN Remzi , ATMACA Şerafettin , YİĞİT Tuncay
Published: October 2023

Real-time anomaly detection in network traffic is a method that detects unexpected and anomalous behaviour by identifying normal behaviour and statistical patterns in network traffic data. This method is used to detect potential attacks or other anomalous conditions in network traffic. Real-time anomaly detection uses different algorithms to detect abnormal activities in network traffic. These include statistical methods, machine learning and deep learning techniques. By learning the normal behaviour of network traffic, these methods can detect unexpected and anomalous situations. Attackers use various techniques to mimic normal patterns in network traffic, making it difficult to detect. Real-time anomaly detection allows network administrators to detect attacks faster and respond more effectively. Real-time anomaly detection can improve network performance by detecting abnormal conditions in network traffic. Abnormal traffic can overuse the network's resources and cause the network to slow down. Real-time anomaly detection detects abnormal traffic conditions, allowing network resources to be used more effectively. In this study, blockchain technology and machine learning algorithms are combined to propose a real-time prevention model that can detect anomalies in network traffic.

Human handwriting is used to investigate human characteristics in various applications, including but not limited to biometric authentication, personality profiling, historical document analysis, and forensic investigations. Gender is one of the most distinguishing characteristics of human beings. From this point forth, we propose a novel end-to-end model based on Convolutional Neural Network (CNN) that automatically extracts features from a given handwritten sample, which contains both handwritten text and numerals unlike the related work that uses only handwritten text, and classifies its owner’s gender. In addition to proposing a novel model, we introduce a new dataset that consists of 530 gender-labeled Turkish handwritten samples since, to the best of our knowledge, there does not exist a public gender-labeled Turkish handwriting dataset. Following an exhaustive process of hyperparameter optimization, the proposed CNN featured the most optimal hyperparameters and was both trained and evaluated on this dataset. According to the experimental result, the proposed novel model obtained an accuracy as high as 74.46%, which overperformed the state-of-the-art baselines and is promising on such a task that even humans could not have achieved highly-accurate results for, as of yet.

Osmanlı Dönemi Han ve Kervansaray Yapılarında Avlu Üzerine Bir İnceleme Güneydoğu Anadolu Bölgesi Örneği
Authors: KAKDAS ATEŞ Dilan , PAYASLI OĞUZ Gülin
Published: October 2023

Avlu; konut mimarisinden başlayarak anıtsal yapı mimarisine kadar kendini gösteren bir terimdir. Ortak toplanma ihtiyacı, sosyal mekân gereksinimi, güvenlikli açık alan kavramları avlu oluşumunun temelini oluşturmaktadır. Milattan önceki dönemlerin kent planlarında kendini gösteren avlu kavramı tüm dönemlerde olduğu gibi Osmanlı devleti döneminde de önemini korumuştur. Anadolu’da hüküm süren Osmanlı devleti inşa ettiği yapılarda avlu kavramını plan düzeninde kullanarak ön plana çıkarmıştır. Selçuklu Devletinden sonra kervansaray geleneğini devam ettiren Osmanlı devleti Güneydoğu Anadolu bölgesinde de avlunun ön planda olduğu eserler bırakmıştır. Çalışma kapsamında; Güneydoğu Anadolu Bölgesinde yer alan Osmanlı dönemi han ve kervansaray yapılarının avlu tipi incelenmiştir. Güneydoğu Anadolu bölgesinde yapılan alan çalışmasında tüm han ve kervansaray yapıları yerinde tespit edilmiştir. Tespit edilen yapılardan planlarına ulaşılamayanların rölövesi alınarak plan çizimi dijital ortamda gerçekleştirilmiştir. Tespit edilen yapılar dönemlerine göre ayrılmıştır. Dönem analizi yapılan yapıların Osmanlı döneminde yoğunlaştığı tespit edilmiştir. Güneydoğu Anadolu bölgesi için literatürde bu kapsamda bir çalışma yapılmadığı görülmüştür. Tespit edilen yapılardan Osmanlı dönemine ait olan yapıların avlu-plan ilişkisi incelenmiştir. Avlu tipine göre yapılar; avlusuz, tek avlulu ve çok avlulu olarak sınıflandırılmıştır. Avlusuz yapılar da Sahınlı/Sahınlı-bitişik olarak ayrılmıştır. Osmanlı dönemine göre avlu biçiminde görülen farklılıklar ele alınmıştır. Çalışmanın amacı; güneydoğu Anadolu bölgesinde gelişen han ve kervansaray mimarisinin avlu tipini dönemine göre ortaya koymaktır. Bu sayede Selçukludan Osmanlıya uzanan kervansaray/han mimarisinin bölgede nasıl şekillendiği tespit edilmek istenmiştir. Sonuç olarak; Osmanlı devleti döneminde şehirleşme artmıştır. Şehirleşme hareketi ile parsel boyutları değişmiştir. Bu değişim Midyat Hayvan Han örneğinde görülmüştür. Kapalı plan tipi örnekleri Diyarbakır ve Şanlıurfa’da yoğunlaştığı için bu bölgelerden örnek yapılar seçilerek plan ölçeğinde inceleme yapılmıştır. Yine çok avlulu örneklere bakıldığında ise güneydoğu Anadolu bölgesinde sadece iki yapıda çok avlulu tip tespit edilmiştir. Gaziantep Anadolu Han ve Diyarbakır Çifte han örneklerinde iki avlulu sistem bulunmaktadır. Günümüzde Çifte han örneğinin ikinci avlusu yıkımdan dolayı detaylı olarak incelenememiştir.

Materials and Methods: This cross-sectional retrospective study included COVID-19 patients diagnosed with SARS-CoV-2 PCR positivity in the first 18 months of the COVID-19 pandemic, between March 2020 and September 2021. We conducted a survey in 2022 to inquire about the participants’ symptoms that lasted three months or more after their own COVID-19 period. All patients were employees of one of the biggest national banks in Turkey. Participants answered a total of 31 questions over the phone. The presence of one or more symptoms persisting ≥3 months was defined as ‘long COVID’. The risk factors associated with ‘long COVID’ were determined.

Results: A total of 1301 patients were included in our study. The median age of patients was 40 (22-57), and 558 (42.9%) were women. 257 (19.8%) patients had ‘long COVID’ symptoms. The most prevalent symptoms were myalgia (14.3%), arthralgia (14.1%), and back pain (13.8%). Female gender (p=0.000, OR=2.19 [95% CI=1.655-2.904]) and diabetes mellitus (p=0.016, OR=2.43 [95% CI=1.177-5.017]) were found as independent risk factors for ‘long COVID’ by multivariant logistic regression analysis.

Conclusion: Female gender and diabetes mellitus are risk factors for ‘long COVID’. Detecting patients with a high risk for developing ‘long COVID’ is crucial for their management during the COVID and post-COVID periods.

The Effect of Prophylactic Carbapenem Use on Outcomes in Acute Pancreatitis: A Systematic Review and Meta-Analysis
Authors: Buyukkoruk Merve , Senturk Ahmet Furkan , Ozger Hasan Selcuk
Published: October 2023

Objective: This study aimed to determine the effect of prophylactic use of carbapenems for acute pancreatitis on clinical outcomes.

Materials and Methods: It was conducted according to the preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by using the keywords “Pancrea* AND carbapenem OR imipenem OR ertapenem OR meropenem OR doripenem.” Primer outcomes were mortality, surgical intervention, and pancreatic and non-pancreatic infection. Subgroup analyses were also performed to reduce the risk of bias.

Results: Ten studies with 4038 patients were included in the meta-analyses. While eight of ten were randomized controlled trials, two were observational studies. The prophylactic use of carbapenems had no statistically significant effect on mortality (OR=0.82, 95% CI=0.65-1.04, I²=0%) and surgical intervention. (OR=0.81, 95% CI=0.57-1.17, I²=0%). However, the real impact of prophylaxis on reducing the incidence of mortality and surgical intervention was uncertain due to the insufficient sample size. The prophylactic use of carbapenems was significantly associated with a lower risk of peripancreatic (OR=0.37, 95% CI=0.25-0.55, I²=61%) and non-pancreatic infection risk (OR=0.60, 95% CI=0.46-0.78, I²=65%). The definitions of infection in the articles were not clear, and the diagnostic approach to infection was based on subjective criteria. In addition, there was inadequate collateral damage and safety assessments. In high-quality studies with a low risk of bias, prophylactic carbapenems had no effect on peripancreatic infection (RR=1.54, 95% CI=0.65-3.47, I²=0%) and non-pancreatic infection (RR=0.72, 95% CI=0.48-1.07, I²=0%).

Conclusion: Although there is a reduction in the infection risk, routine carbapenem use in acute pancreatitis cases should not be recommended based on current evidence. Cooperation with Infectious Disease specialists and developing diagnostic algorithms are required instead of routine prophylaxis to prevent infection, especially non-pancreatic infection.

Bibliometric Analysis of the Publications on Middle East Respiratory Syndrome Coronavirus Published Between 2012-2022
Authors: Alkan Sevil , Gurbuz Esra
Published: October 2023

Objective: This study aimed to conduct a bibliometric analysis of the global scientific output related to the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) between 2012 and 2022.

Materials and Methods: The Web of Science database was searched for articles on MERS-CoV published between 2012 and 2022 for bibliometric analysis. The parameters such as publication year, publication type, funding agencies, research institutions, journals, impact factors, language, and citation numbers of articles were analyzed.

Results: We included 1475 articles on MERS-CoV from 86 countries. The United States was the most published country on MERS-CoV, with 487 articles. The Saudi Ministry of Health (7.53%), King Saud bin Abdulaziz University for Health Sciences (6.92%), and The Egyptian Knowledge Bank (6.64%) were the most published institutions. The researchers who published the most on MERS-CoV were from Saudi Arabia. One thousand two hundred six funding agencies funded publications on MERS-CoV, most of which were funded by agencies from the United States.

Conclusion: MERS-CoV remains important because no treatment and no vaccine have been found since it was first detected, and accordingly, it continues to affect the world with new outbreaks and high mortality rates. In addition, experiences with MERS-CoV during the coronavirus disease 2019 (COVID-19) pandemic have guided new research on COVID-19, so scientific interest in MERS-CoV is still ongoing.

Geländemauer, Limen Kleistos ve Hekatomnos Hanedanlığı Dönemi Liman Kentlerinin Savunma Sistemine Bir Bakış
Authors: BÜYÜKÖZER Aytekin
Published: October 2023

Bu makale, Karia Bölgesi’ndeki liman kentlerinin Hekatomnos Hanedanlığı Dönemindeki savunma stratejisine odaklanmaktadır. MÖ 5. ve 4. yüzyıllarda Atina, Sparta ve Pers donanmalarının Kaunos, Iasos, Knidos ve Halikarnassos gibi kentlerin limanlarını üs olarak kullanması, gerek ticari gerekse askeri anlamda liman kentlerinin ne derece önemli olduğunu açıkça ortaya koymuştur. MÖ 4. yüzyılın başlarında özerk bir satraplık haline gelen Karia Bölgesi’nde satrap olarak görevlendirilen Hekatomnos ve ardılları liman kentlerinin bölge savunması için önemini kavramış ve savunma stratejilerini buna göre oluşturmuşlardır. Maussollos ile başlayan şehirleşme politikası kapsamında ya yeni liman kentleri kurulmuş ya da var olan kentler genişletilip güçlendirilmiştir. Bu kentlerin yer seçimindeki belirleyici faktörler ise yerleşimin çevresinin Geländemauer tipi sur yapmaya elverişli zirve ve sırtlara sahip olması ayrıca kentin, limanın, donanmanın ve kente gelen gemilerin güvenliğini sağlamak için Limen Kleistos oluşturmaya uygun, korunaklı koyların bulunmasıdır. Kentlerin bu şekilde güvene alınması, deniz ticareti için stratejik bir konumda olan bölgenin, Ege ve Doğu Akdeniz ile ticari ve kültürel ilişkilerini geliştirebilmesine de olanak tanımıştır. Hekatomnidler, denizle doğrudan teması olan yerleşimler oluşturabilmek veya var olan yerleşimleri büyüterek güçlendirmek için iç bölgeleri belli oranda terk etmişler ve savunma stratejilerini genellikle liman kentleri üzerine kurmuşlardır. Bu kapsamda Hekatomnidler anakara ile sınırlı kalmayarak Rhodos, Kalymnos, Nisyros, Telos, Kos gibi adalarda düzenli deniz üsleri sağlayabilecek limanları çoğaltarak hem savunma hem ticari anlamda bölgenin denizcilik potansiyelini artırma arzusunda olmuşlardır. Böylece kuzey Karia’dan Lykia’ya kadar uzanan bölge ile birlikte adalardaki liman kentleriyle, Hekatomnos Hanedanlığı hakimiyeti altındaki toprakların savunmasında etkin bir hat oluşturmuşlardır.

Reimagining Educational Leadership in the Caribbean
Authors: Thompson Canute S.
Published: October 2023

In Reimagining Educational Leadership in the Caribbean, Canute S. Thompson contends that postmodernism ought to be the guiding construct in considering leadership in education and management. Postmodernism challenges convention, embraces otherness and champions the diversification of authority. Educational leadership in a postmodern era must be informed by an approach of radical inclusivity and power sharing. This approach is predicated on the assumption that students are capable of offering meaningful suggestions for improvements in the processes of teaching and delivery of learning and that practitioners possess the knowledge and experience to inform policy. At the heart of this proposed new approach to educational leadership is the contention that zones of exclusive expertise have been overturned by the advent of postmodernism: the focus of assessments and the usefulness of ideas should not be on whose ideas they are but on the merits of these ideas, regardless of source. Drawing on his original theory of Proposition MRM (modelling, respect, motivation), Thompson explores issues that face educational and other leaders in the Caribbean in a manner that has not yet been undertaken so extensively. The author examines the relationship between Proposition MRM and various elements of educational policy and practice, including critical thinking, ethics, pedagogy, sustainable development, and technical and vocational education and training. Reimagining Educational Leadership in the Caribbean is practitioner-sensitive and is written in a non-technical style to be accessible to educators at all levels and others interested in social change.
Elementos mitológicos y arquetipales en el cine
Authors: Martín Muñoz Teresa
Published: October 2023

La Princesa Prometida es una producción cinematográfica de culto repleta de elementos simbólicos y contenidos mitológicos. Este estudio sigue la línea de trabajos que afirman que la ficción proyectada en las películas tiene el potencial de ayudar en el camino de la individuación y a crecer en autoconciencia a través de hacer conscientes los elementos simbólicos. (Hauke, 2009; Izod,2000). Partiendo de la noción de inconsciente colectivo de C. G. Jung y «el viaje del héroe» de J. Campbell, se realiza un análisis de los contenidos mitológicos y arquetípicos para aproximarnos a lectura del quinto arte desde una perspectiva psicológica profunda.
