Ποσοτική και ποιοτική αξιολόγηση των παραμέτρων της μικρογραφικής Χειρουργικής κατά Mohs
Authors: Εξαδάκτυλου Δέσποινα
Published: December 2021

Εισαγωγή: Η Μικρογραφική Χειρουργική κατά Mohs (MMX), έχει ένδειξη για την αντιμετώπιση νεοπλασμάτων του δέρματος και των βλεννογόνων και λόγω του μικροσκοπικού ελέγχου, προσφέρει υψηλά ποσοστά ίασης και διατήρησης φυσιολογικού ιστού. Σκοπός της μελέτης: Σύγκριση της ΜΜΧ με τη συμβατική χειρουργική αφαίρεση ως προς τη μέγιστη διατήρηση υγιούς ιστού κατά τη θεραπεία δερματικών καρκίνων στην περιοχή της κεφαλής. Υλικά και μέθοδοι: Η παρούσα μελέτη αφορά σε δύο ομάδες ασθενών. Η Ομάδα Α περιλαμβάνει 310 ασθενείς οι οποίοι προσήλθαν για αντιμετώπιση νεοπλασμάτων του δέρματος με την Mohs Μικρογραφική Χειρουργική (ΜΜΧ). Η Ομάδα Β αφορά 177 ασθενείς οι οποίοι υποβλήθηκαν σε συμβατική χειρουργική αφαίρεση για καρκινώματα του δέρματος και εξετάστηκαν 47 ιστολογικές διαφάνειες μόνιμων παρασκευασμάτων σε παραφίνη. Για τη σύγκριση της διατήρησης υγιούς ιστού, δημιουργήσαμε την 'Ομάδα Α1' η οποία περιλαμβάνει 245 ασθενείς της Ομάδας Α και την 'Ομάδα Β1' η οποία περιλαμβάνει 27 ασθενείς της Ομάδας Β, με ΒΚΚ στην περιοχή της κεφαλής. Αποτελέσματα: Στα δείγματα που αναλύσαμε στην παρούσα μελέτη, προκύπτει ότι η σχέση 'ελλείμματος: όγκου’ είναι στατιστικά σημαντικά μικρότερη με την χρήση συμβατικής χειρουργικής αφαίρεσης σε σύγκριση με την χειρουργική κατά Mohs. Συμπέρασμα: Η Μικρογραφική Χειρουργική κατά Mohs, αποτελεί μια εξαιρετική μέθοδο για την αντιμετώπιση των καρκινωμάτων. Στην παρούσα μελέτη, από την ανάλυση των στοιχείων δεν υπάρχει πλεονέκτημα όσον αφορά τη διατήρηση υγιούς ιστού με την αντιμετώπιση των όγκων με ΜΜΧ αλλά δεν υπάρχουν δεδομένα μακροχρόνιας παρακολούθησης των ασθενών και καταγραφής υποτροπών στις δύο ομάδες.

Authors: Μπάσιος Νεόφυτος
Published: December 2021

Εισαγωγή:Η οξεία παγκρεατίτιδα (ΟΠ) αποτελεί μια νόσο που αφορά μεγάλο ποσοστό του παγκόσμιου πληθυσμού. Χαρακτηρίζεται από βλάβη του παγκρεατικού ιστού, που οδηγεί σε μορφολογικές μεταβολές και παγκρεατική δυσλειτουργία. Οι κυριότεροι παράγοντες κινδύνου είναι η χολολιθίαση και ο αλκοολισμός. Προκαλεί επιπλοκές σε απομακρυσμένα όργανα, όπως είναι ο πνεύμονας. Η απιγενίνη αποτελεί ένα ισχυρό αντιφλεγμονώδες φλαβονοειδές, που μπορεί να χορηγηθεί σε πειραματικό μοντέλο στοχεύοντας στην πρόληψη και στη θεραπεία της ΟΠ. Σκοπός της έρευνας είναι η εκτίμηση της ευεργετικής δράσης της απιγενίνης στο πνευμονικό παρέγχυμα σε πειραματικό μοντέλο επίμυος μετά από πρόκληση ΟΠ.Μέθοδοι: Χρησιμοποιήθηκαν τομές παραφίνης από πνεύμονες 126 επίμυων τύπου Wistar. Τα δείγματα χωρίσθηκαν σε τρεις ομάδες: S (οι επίμυες υποβλήθηκαν σε εικονικό χειρουργείο), C (οι επίμυες υποβλήθηκαν σε χειρουργείο πρόκλησης οξείας παγκρεατίτιδας), Α (οι επίμυες υποβλήθηκαν σε χειρουργείο πρόκλησης οξείας παγκρεατίτιδας και χορήγηση απιγενίνης). Οι ομάδες C και Α διαχωρίσθηκαν περαιτέρω ανάλογα με την χρονική στιγμή που διενεργήθηκε η ευθανασία. Στις τομές πραγματοποιήθηκε χρώση αιματοξυλίνης εωσίνης και έμμεση ανοσοϊστοχημεία για τον δείκτη MMP-9 καθώς και για τους δείκτες HSP60 και HSP70 .Αποτελέσματα: Η έκφραση του MMP-9 βρέθηκε υψηλότερη με στατιστικά σημαντική διαφορά στην ομάδα A συγκριτικά με τις άλλες δυο ομάδες, στις 12h και στις 24h. Στις 48h, η έκφραση ήταν υψηλότερη στην ομάδα C σε σχέση με τις άλλες δυο ομάδες. Τέλος, στις 72h, τα επίπεδα ήταν χαμηλότερα στην ομάδα Α συγκριτικά με τις άλλες δύο ομάδες. Η έκφραση των HSP60 και ΗSP70 ηταν υψηλότερη με στατιστικά σημαντική διαφορά στην ομάδα Α συγκριτικά με τις άλλες δυο ομάδες, στις 12h και στις 24h. Για τον δείκτη HSP60 τα αποτελέσματα παρέμειναν τα ίδια και στις 48 ώρες, ενώ για τον HSP70 δεν υπήρχε στατιστικά σημαντική διαφορά μεταξύ των ομάδων. Τέλος τόσο ο HSP60 όσο και ο HSP70 είχαν στατιστικά σημαντικά υψηλότερη έκφραση στην ομάδα C στις 72h, σε σχέση με τις ομάδες Α και S.Συμπεράσματα: Συμπερασματικά, η προστατευτική δράση της απιγενίνης στο πνευμονικό παρέγχυμα, σε πειραματικό μοντέλο οξείας παγκρεατίτιδας είναι ενθαρρυντική. Εντούτοις απαιτείται η διενέργεια περισσότερων μελετών, προκειμένου να επιβεβαιωθούν τα αποτελέσματα.

Authors: Grisales-Romero Hugo , Piñeros-Jiménez Juan Gabriel , Nieto Emmanuel , Porras-Cataño Sandra , Montealegre Nora , González Difariney , Ospina Dorian
Published: December 2021

Background: Exposure to 2.5-micron diameter air pollutants (PM2.5) has been associated with an increased risk of illness and death worldwide; however, in Latin American health impacts assessment of this risk factor is scarce. Medellín is one of the most polluted cities in the region, with a population growth rate that is twice as high as that of other Colombian cities, which implies a growing population at risk.

Methods: A descriptive study of the disease burden was carried out using the city as the unit of observation. Health events were selected based on epidemiologic evidence and the availability of the population attributable fraction associated with PM2.5. The mortality records were taken from the module of deceased of the Single Registry of Affiliates of the Health System; the morbidity records were taken from the Individual Health Services Registries. For the estimation of the burden of disease, the current Global Burden of Disease guidelines were followed.

Results: Attributable disability-adjusted life years to exposure to ambient PM2.5 pollution (DALYsPM2.5) constituted 13.8% of total burden of the city. Males showed the greatest loss of DALYsPM2.5 due to acute events, while in women the greatest loss was due to chronic events. Ischemic heart disease, chronic diseases of the lower respiratory tract, and influenza and pneumonia were the events that contributed the most to DALYsPM2.5. 71.4% of the DALYsPM2.5 corresponded to mortality, mainly in the population over 65 years of age. Regarding attributable morbidity, acute events were more prevalent in both sexes, especially due to respiratory diseases

Conclusion: Premature death among the elderly population has the greatest weight on burden of disease attributable to ambient PM2.5 pollution, mainly due to respiratory and cardiovascular diseases, without significant differences according to gender.

Published: December 2021

Background: Bone marrow involvement is an important aspect of determining staging of disease and treatment for childhood neuroblastoma. Current standard of care relies on microscopic examination of bone marrow trephine biopsies and aspirates respectively, to define involvement. Flow cytometric analysis of disaggregated tumour cells, when using a panel of neuroblastoma specific markers, allows for potentially less subjective determination of the presence of tumour cells.

Methods: A retrospective review of sequential bone marrow trephine biopsies and aspirates, performed at Great Ormond Street Hospital, London, between the years 2015 and 2018, was performed to assess whether the addition of flow cytometric analysis to these standard of care methods provided concordant or additional information.

Results: There was good concurrence between all three methods for negative results 216/302 (72%). Positive results had a concordance of 52/86 (61%), comparing samples positive by flow cytometry and positive by either or both cytology and histology.  Of the remaining samples, 20/86 (23%) were positive by either or both cytology and histology, but negative by flow cytometry. Whereas 14/86 (16%) of samples were positive only by flow cytometry.

Conclusions: Our review highlights the ongoing importance of expert cytological and histological assessment of bone marrow results. Flow cytometry is an objective, quantitative method to assess the level of bone marrow disease in aspirates.  In this study, flow cytometry identified low-level residual disease that was not detected by cytology or histology. The clinical significance of this low-level disease warrants further investigation.
Recognizing and mediating bureaucratic barriers: increasing access to care through small and medium-sized private providers in Kenya
Authors: Suchman Lauren , Owino Edward , Montagu Dominic
Published: December 2021

Background: Equitable access to health services can be constrained in countries where private practitioners make up a large portion of primary care providers. Expanding purchasing arrangements has helped many countries integrate private providers into government-supported payment schemes, reducing financial barriers to care. However, private providers often must go through an onerous accreditation process to enroll in these schemes. The difficulties of this process are exacerbated where health policy is changed often and low-level bureaucrats must navigate these shifts at their own discretion. This paper analyzes one initiative to increase private provider accreditation with social health insurance (SHI) in Kenya by creating an intermediary between providers and “street-level” SHI bureaucrats.

Methods: This paper draws on 126 semi-structured interviews about SHI accreditation experience with private providers who were members of a franchise network in Kenya. It also draws on four focus group discussions conducted with franchise representatives who provided accreditation support to the providers and served as liaisons between the franchised providers and local SHI offices. There was a total of 20 participants across all four focus groups.

Results: In a governance environment where regulations are weak and impermanent, street-level bureaucrats often created an accreditation process that was inconsistent and opaque. Support from the implementing organizations increased communication between SHI officials and providers, which clarified rules and increased providers’ confidence in the system. The intermediaries also reduced bureaucrats’ ability to apply regulations at will and helped to standardize the accreditation process for both providers and bureaucrats.

Conclusions: We conclude that intermediary organizations can mitigate institutional weaknesses and facilitate process efficiency. However, intermediaries only have a temporary role to play where there is potential to: 1) directly increase private providers’ power in a complex regulatory system; 2) reform the system itself to be more responsive to the limitations of on-the-ground implementation.
Implementation of telemedicine consultations for people with mental health conditions in the community: a protocol for a systematic review
Authors: Galvin Emer , Desselle Shane , Gavin Blánaid , Quigley Etain , Flear Mark , Kilbride Ken , McNicholas Fiona , Cullinan Shane , Hayden John
Published: December 2021

Background: The COVID-19 pandemic response has led to an exponential increase in the use and spread of telemedicine internationally. In community mental health care settings, telemedicine services were implemented within a few weeks, with little time for rigorous planning. Despite the reported acceptability of telemedicine by patients and clinicians, barriers to its implementation have come to light. There is now a need to investigate these barriers, and facilitators, as telemedicine begins to show potential promise beyond the pandemic. We propose a review that aims to identify the factors affecting the implementation of telemedicine consultations for patients with mental health conditions in the community.

Methods: A systematic review will be conducted and reported according to the PRISMA guidelines. Five electronic databases will be searched using a pre-defined search strategy from 2016 to 2021. Only studies of synchronous, interactive telemedicine consultations conducted via video, phone or live messaging between patients and providers will be included. Quantitative, qualitative and mixed methods studies will be eligible for inclusion. Only studies published in the English language will be included. Titles and abstracts will be screened by two reviewers. Full text articles will be screened by a single reviewer, with a random 20% sample screened by a second reviewer. The methodological quality of studies will be assessed using the Mixed Method Appraisal Tool (MMAT) by two reviewers. Data will be extracted and tabulated to address the aims of the review. A narrative synthesis will be conducted and reported factors will be mapped to the domains of the Consolidated Framework for Implementation Research (CFIR).

Conclusion: By identifying the factors that influence the implementation of telemedicine consultations for patients with mental conditions in the community, consideration can be given to both barriers and facilitators that could be addressed in future mental health services planning.

Published: December 2021

Background: As of August 2021, every region of the world has been affected by the COVID-19 pandemic, with more than 196,000,000 cases worldwide.

Methods: We analysed COVID-19 cases among travellers from mainland China to different regions and countries, comparing the region- and country-specific rates of detected and confirmed cases per flight volume to estimate the relative sensitivity of surveillance in different regions and countries.

Results: Although travel restrictions from Wuhan City and other cities across China may have reduced the absolute number of travellers to and from China, we estimated that up to 70% (95% CI: 54% - 80%) of imported cases could remain undetected relative to the sensitivity of surveillance in Singapore. The percentage of undetected imported cases rises to 75% (95% CI 66% - 82%) when comparing to the surveillance sensitivity in multiple countries.

Conclusions: Our analysis shows that a large number of COVID-19 cases remain undetected across the world. These undetected cases potentially resulted in multiple chains of human-to-human transmission outside mainland China.

Accounting Performance Goals in CEO Compensation Contracts and Corporate Risk Taking
Authors: Chen Clara Xiaoling , Kim Minjeong (MJ) , Li Laura Yue , Zhu Wei
Published: December 2021

This study provides the first large-sample archival evidence on the impact of three commonly used accounting performance goals (thresholds, targets, and maximums) in CEO compensation contracts on corporate risk taking. Using proxy statement disclosure on performance goals for CEOs of U.S. public companies, we find that lower thresholds and higher maximums are associated with greater corporate risk taking, and these results are more pronounced when CEOs have greater incentives to achieve accounting performance goals or have lower innate risk aversion. In addition, we find that target difficulty is not significantly associated with corporate risk taking after controlling for thresholds and maximums. Finally, we find that CEO compensation contracts are more likely to have lower thresholds and higher maximums when risk taking is more value-enhancing or when R&D investment is more profitable, consistent with boards setting performance goals to induce an appropriate amount of corporate risk taking. Our study contributes to the accounting literature on target setting and corporate risk taking by identifying accounting performance goals as a tool in executive compensation contract design to influence risk taking.

Communication barriers that affect medication adherence in patients with learning disabilities
Authors: Hignett Jamara
Published: December 2021

Communication formulates a large part of a consultation and as a practitioner, it is vital to communicate effectively with a patient. Jamara Hignett provides an overview of the communication barriers that affect medication adherence in patients with learning disabilities

Having a disability that affects communication can cause particular problems in primary care as inadequate communication can lead to the wrong diagnosis, poor assessments and inadequate health care ( Murphy, 2006 ). All patients are entitled to accessible and appropriate information on prescribed medication to facilitate a deeper understanding of the benefits and harms of treatment ( Grime et al, 2007 ). Reasonable adjustments should be made for learning difficultly patients and this can be in the form of easy reads guides that incorporate larger text, simple information and pictorial explanations. Communication passports are a tool used by people with learning disabilities; these provide both a practical and person-centred approach to passing on key information about people with complex communication difficulties ( Nursing Times, 2018 ). They provide information about the communication needs and health needs of a patient which is useful to assist in bridging the communication gap between nurse practitioner and patient. In a time of technological advancements, a move towards digital passports would be more beneficial with regular updates from the multidisciplinary team. This in turn can be shared across numerous health platforms the patient might come into contact with, allowing the nurse practitioner to better prepare for the patient prior to their consultation. Education on learning disabilities is an area of training that is lacking in general practice; there have been no provisions made to make the training mandatory. Incorporating mandatory yearly staff training will ensure nurse practitioners have the tools and knowledge to adapt communication techniques during a consultation.
Imagens, enquadramentos e quadriculamentos familiares no novo cinema argentino: restos e rastros da ditadura?
Authors: Fischer Sandra , Vaz Aline
Published: December 2021

O presente estudo busca identificar restos e rastros de realidades presentes nos filmes La Ciénaga (Lucrecia Martel, 2001) e Leonera (Pablo Trapero, 2008) – com base em fatos de ordem política e governamental que tiveram lugar na Argentina e levando em conta manifestações, declarações explícitas dos cineastas em foco. Considerando a indefinição de fronteiras que se estendem entre a razão dos fatos e a razão da ficção, analisamos nas imagens das topologias da casa familiar o princípio do quadriculamento que, inscrito nas abstrações dos convívios e nas concretudes dos cômodos domésticos, configura e apresenta, nas obras em foco, peculiaridades e vestígios que inferem uma memória pós-ditatorial.

Objectives: The LI11 (Quchi) acupuncture point has always been included in the Seven acupoints for stroke; however, additional LI11 acupuncture research is needed. In this study, the effect of LI11 acupuncture on cerebral blood flow of the anterior cerebral arteries (ACA) and middle cerebral arteries (MCA) was investigated.Method: This study included 10 healthy young male subjects. Cerebral blood flow velocity and cerebrovascular reactivity were measured using transcranial Doppler sonography. Changes in hyperventilation-induced carbon dioxide (CO2) reactivity and modified ACA and MCA blood flow velocity at 40 mmHg (CV40), blood pressure, and heart rate were observed before and after LI11 acupuncture treatment.Results: A statistically significant increase in contralateral anterior cerebral artery CO2 reactivity (p=0.036) and decrease in contralateral middle cerebral artery CV40 (p=0.047) were observed. No significant difference in mean blood pressure was shown. A statistically significant increase in heart rate occurred after LI11 acupuncture; however, it was not clinically significant as there were negligible changes in the heart rhythm.Conclusions: LI11 acupuncture treatment could improve cerebral blood flow velocity. These results might be explained by regulating endothelium-dependent vessel dilation in the anterior cerebral artery region.Trial registration: This trial has been registered with Clinical Research Information Service, a service of the Korea Centers for Disease Control and Prevention: KCT0004494 (retrospectively registered). https://cris.nih.go.kr/cris/search/search_result_st01.jsp?seq=15359

Published: December 2021

The improvement of biotechnological processes capable of transforming agro-industrial waste into products with high added value has stood out in the area of renewable energies, promoting positive impacts to the environment. Thus, the present work evaluated the influence of nickel on the conversion of fermentable sugars, present in the green coconut shell hydrolyzate (GCSH), into butanol and other products. Fermentation assays were performed at 37 °C, starting with 19.4 g.L-1 of sugars and 1.0 g.L-1 of inoculum (C. beijerinckii). The GCSH was supplemented with tryptone, yeast extract, ammonium acetate, minerals and phosphate buffer. Two conditions were tested: with and without addition of nickel. Concentrations of sugars (glucose and xylose), intermediate products (organic acids), acetone, butanol, and ethanol were determined by high performance liquid chromatography (HPLC). The results show that the butanol production was higher from GCSH without addition of nickel, reaching a concentration of 2.14 g.L-1 of butanol. Therefore, the presence of nickel in the hydrolyzate was not favorable in the production of butanol under the studied process conditions.
Single-beam highly sensitive magnetic field gradiometer based on the atomic spin-exchange relaxation-free effect

Published: December 2021

This paper presents a single-beam atomic magnetic field measurement gradiometer, which is a highly sensitive magnetic field gradient measuring instrument based on the atom spin-exchange relaxation-free (SERF) effect. The reflective detection optical path structure is adopted. The spin precession signals of an atom under incident and reflected light are different. There is also a difference in the corresponding magnetic field distribution. The final measurement of magnetic field gradients is conducted based on the different magnetic field distributions. The single-beam high-sensitive magnetic field gradiometers based on the atomic SERF effect are more sensitive than conventional two-probe magnetic field gradiometers or two-beam magnetic field gradiometers. The gradiometers are not affected by a difference in the detected optical power in the single-beam detection light measurements. The reflector uses an angular cone prism for two-dimensional magnetic field gradient measurements and is simple to construct. The single-beam highly sensitive magnetic field gradient measurement instrument based on the atomic SERF effect has a reflective detection optical path structure. It uses a quarter-wave plate to achieve the initial signal phase elimination of both incident and reflected signal and an angular cone prism as a reflector to achieve two-dimensional measurement.

Here, the laser beam interference technique was used to realize the periodic grating structures of the shape-memory polymer, and memory and recovery of the grating structures were performed. A one-dimensional grating structure was fabricated from dual-beam interference lithography of a nanosecond laser and underwent pressure in a condition of 195°C. The vertical height of the grating was reduced, and the diffraction light was weakened. When the sample was cooled down to room temperature, the morphology of the grating could be kept. After raising the ambient temperature of the sample to 120°C, the morphology of the grating was recovered to the original state, which realized the shape-memory function.
Creation of topological charges by the spontaneous symmetry breaking phase transition in azo dye-doped nematic liquid crystals
Authors: Sim Yonggi , Choi Hyunhee
Published: December 2021

Liquid crystals are anisotropic fluids with long-range directional order. They can be easily used to create topological defects, but creating a controlled topological defect is difficult and involves many tasks and complex processes. However, in our study, we were able to easily generate disclinations in the symmetry-breaking boundaries of an azo dye-doped nematic liquid crystal cell owing to photoisomerization and symmetry-breaking isotropic-nematic phase transition. The method proposed here marks the starting point for the easier control of topological defects in liquid crystals.

All-inorganic CsPbI3 perovskite quantum dots (QDs) with efficient pure red emission are broadly researched for applications as next-generation light emitters. Their optical stability against humidity and water, on the other hand, is a great barrier that needs to be significantly enhanced. In this study, polyvinylidene fluoride (PVDF) nanofibers (NFs) were synthesized by electrospinning and CsPbI3 QDs were effectively composited into the interior of the PVDF NFs matrix by dip-coating. The CsPbI3 QDs/PVDF NFs composites exhibited a high red photoluminescence (PL) quantum yield of ∼11% with the PL peak slightly blue shifted compared with the bare QDs. Due to the high hydrophobicity, porosity, and excellent thermal insulation of the PVDF NFs and uniform dispersion of the QDs in the NFs network, the composite membrane demonstrated excellent water, thermal, and UV light resistance. In addition, the CsPbI3 QDs/PVDF NFs composites were revealed to exhibit high designability, flexibility, and repeatability, indicating significant potential for different light-emitting applications.
‘A very very long amount of time passes’: Slowness, cinema and Annie Baker’s The Flick (2013)
Authors: Johnson David T.
Published: December 2021

Annie Baker’s 2013 play The Flick prompted divisive reactions from its audience from the time of its original run, ones largely based on the play’s feeling extremely slow. Setting out from the intersection of the play’s temporal affect and the play’s setting – a movie theatre – this article builds on recent work on slow-cinema scholarship, particularly as it relates to theatrical exhibition, to explore contemporary discourse on both slowness and cinema. Going further, it sets this work against the backdrop of broader, multi-disciplinary conversations about the cultures of speed and slowness, before considering the particular slowness in The Flick as well as its evocation of the theatrical experience. Finally, the article concludes by asking what it means today to attend the cinema.
Indebtedness and the road to monetary sovereignty following the international recognition of Montenegro in 1878
Authors: Raspopovic Radoslav
Published: December 2021

The paper is dedicated to furthering the research into different aspects of Montenegrin sovereign status gained the Congress of Berlin, with a focus on the country’s financial sovereignty. Becoming an independent state had great historical significance for Montenegro, marking the realisation of the centuries-old aspirations for liberation. Still, exercising sovereign power proved challenging for Montenegro as the country was still an underdeveloped, agrarian country with a high percentage of illiterate population, scarce human resources and modest economic opportunities. Aside from this, there were still many congressional restrictions to exercising the rights acquired by gaining access to the sea. The author seeks to determine the reasons for the high level of indebtedness, as well as the decisions made in trying to resolve the challenges in maintaining the country’s financial sovereignty. The author also touches upon the broader subject of the role of gold standard in international trade and argues to which extent Montenegro was able to adhere to this internationally accepted standard, having established its banking institutions and having introduced its own currency. Considering that this paper is a part of the scientific research work on the project ‘Montenegro on the political and cultural map of Europe’ (CLIO MAP), exhibiting the reasons for minting the first Montenegrin coin is but a way to examine a segment in exibiting the country’s sovereign status acquired at the Congress of Berlin.
A Conquista de Tavira aos Mouros
Authors: Henriques Antonio Castro
Published: December 2021

Este trabalho propõe uma reconstrução crítica da conquista cristã de Tavira. De acordo com a fonte narrativa mais antiga (a Crónica de Portugal de 1419), este acontecimento deu-se em 1242 e foi uma consequência acidental do massacre pela população muçulmana dos ditos “Sete Mártires” de Tavira (seis freires de Santiago e um mercador). Recorrendo a materiais novos e outros há muito conhecidos, propõe que Tavira tenha sido ocupada na sequência de uma campanha a 11 de junho de 1239, enquanto o “Martírio” ocorreu num dia 9 de julho cerca de uma década depois, possivelmente em resultado de um confronto entre a população de Tavira e cavaleiros castelhanos de Santiago. Estas propostas e datas constituem contributos importantes para três áreas: a crítica da Crónica de Portugal de 1419, o estabelecimento de uma sequência fiável dos acontecimentos militares e a memória e identidade da sociedade criada pela Reconquista.

Background and Aim: Shepherds are in constant contact with animals, and they are potential hosts for the transmission of zoonoses. This study aimed to assess the perceptions of shepherds in Cameroon's West region regarding zoonotic diseases.

Materials and Methods: A cross-sectional study was conducted from August to October 2017, on 218 shepherds. The data were collected using semi-structured interviewer-administered questionnaires. The participants were assessed on their knowledge, attitudes, and practices that might expose them to bovine zoonose transmission, and the data were analyzed with R, version 2.13.0. Descriptive statistics were generated, and the association between socio-demographic characteristics and knowledge was explored using the Chi-square test.

Results: Out of the 218 herdsmen, (205/218) 94% did not have any education, and (195/218) 89.5% did not know the definition of zoonosis. There was a correlation between the level of education and knowledge of the definition of zoonosis: About (162/218) 74.6% cited tuberculosis as a zoonosis, (62/218) 28.4% said the main modes of transmission were by ingestion of contaminated milk, and (66/218) 30.3% by consumption of contaminated meat. Abortions during the third trimester of gestation, combined with the presence of hygroma, were described by (130/218) 59.6% of the participants as brucellosis symptoms. In terms of practices and attitudes, (187/218) 85.8% and (50.14/218) 23.0% of the participants confirmed that they consumed raw milk and raw meat, respectively. Almost all (214/218) 98.1% interviewees stated that blood consumption is forbidden. In case of suspicion of disease, (204/218) 93.6% maintained that they treated sick animals without a veterinary prescription, and (209/218) 95.9% left the carcasses in the wild. After contact with animals, (181/218) 83.3% washed their hands. Finally, (192/218) 88.3% would like to be informed about zoonoses.

Conclusion: The level of knowledge about zoonotic diseases was low; a high percentage of shepherds followed inadequate hygiene practices and expressed concern about zoonoses. As a result, they are at risk of exposure to pathogens. It would be in the interest of public health to develop training programs for shepherds and livestock owners to mitigate zoonotic risks.

Tanulmányunkban arra keressük a választ, hogy a magyar kormányzat járványkezelési intézkedései a pandémia első szakaszában hogyan befolyásolták az online platformokon észlelt kommunikációs aktivitást. Primer kutatásunk célja a járványkezeléssel kapcsolatos kommunikáció lakossági megítélésének felmérése. Kutatásunkban a maszkviseléssel és a kórházi ágyak gyors felszabadításával kapcsolatos kommunikációt vizsgáltuk netnográfiai módszerrel, 5 online fórum összesen 2000 kommentjének elemzésével. A fórumok kommentjei alapján az online közösségben nagyon szélsőséges és eltérő vélemények (szkepticizmus, megbotránkozás, vádaskodás, elfogadás) alakultak ki az egészségügyi kommunikáció pontosságáról és megbízhatóságáról. Kutatásunk eredményei azt jelzik, hogy a COVOD-19 idején mind a politikai, mind az egészségügyi kommunikáció megosztotta a magyar lakosság véleményét az online platformokon.

A jelen tanulmány egy nagyobb ívű kutatásnak ágyaz meg, amely különböző régiók kortárs hangversenytermi zenei kultúráit vizsgálja és hasonlítja össze egymással, külön figyelmet szentelve azoknak a jegyeknek, amelyek alapján azok disztinktív profillal jelenthetnek meg a globális téren belül. Kutatásom első fázásában magyar és román zeneszerzőket kértem fel közreműködésre. A résztvevő tizennyolc zeneszerző mindegyike számára ugyanazt a hat kérdésből álló kérdőívet küldtem el, valamint arra kértem fel őket, hogy küldjék el három olyan zeneművük kottáját, amelyet az elmúlt tíz éven belül írtak, és eddigi munkásságukra nézve reprezentatívnak tartanak. A kérdések jellemzően két perspektíva köré csoportosulnak: a múlt (egyéni háttér, tanulmányok, történetszemlélet), valamint a jelen (társadalmiság, szerepvállalások, nemzetközi integráció) egyéni megítélése köré. A 30-45 év közti életkori behatárolás lehetővé tette azt is, hogy a megkérdezettek egyenlő távolságból és rálátással tudtak reflektálni mestereik generációjának, valamint a jelenleg feltörekvő, húszas éveikben járó zeneszerzők munkásságára.
Szimbólumok és/vagy átmenetek a pedagógiában
Authors: Hevesi Tímea Mária
Published: December 2021

A globalizáció folyamatában a személyes kapcsolatokon alapuló közösségek kialakítása egyre nagyobb feladatot jelent a pedagógusok számára. Az emberi közösségeket átható, összefogó szimbolizációs folyamat miatt a szimbólumok segíthetnek a közösségteremtésben (Kapitány, Kapitány 2020). A szimbólum átmenetet is jelöl, amelyben átalakulás történik (Tánczos 2007), ezáltal elősegíthető a tanulók képességfejlesztése is (Kambouri, Pieridou 2016). Az archetipikus szimbólumok beillesztését már javasolják a pedagógiai munkába (Mayes 2020). A szimbólumpedagógia elnevezést olyan pedagógiai módszer alkalmazására használjuk, mely az analógiás gondolkodásmódon alapul és archetipikus szimbólumok által archaikus élmények megtapasztalására ad lehetőséget (Hevesi 2019). Kutatásunkban a szimbólumpedagógiában rejlő lehetőségeket tárjuk fel.

The corrosion inhibition consequence of 5-(4-aminophenyl)-1,3,4-oxadiazole-2-thiol (APOT) and 5-(4-methylphenyl)-1,3,4-oxadiazole-2-thiol (MPOT) were accomplished by employing weight loss measurement, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization measurement and scanning electron microscope (SEM). An impact of immersion time 12.0 h and different temperatures (298, 308 and 318 K) with solution of 1.0 M HCl, which include various concentration of inhibitor at the corrosion of mild steel were designed. Weight loss measurement showed that with enhancing the concentration of these studied inhibitors the percentage inhibition efficiency (IE%) enhances, but corrosion rate (CR) diminishes while reverse condition in case of temperatures change. The electrochemical impedance spectroscopy examine pointed out that the charge transfer resistance (Rct) values enhances and consequently the double layer capacitance (Cdl) values diminishes with rising each inhibitor concentration in 1.0 M HCl and also there is a formation of adsorption coating at the metal surface. Polarization measurement showed that both APOT and MPOT perform as mixed type corrosion inhibitors. Furthermore, the adsorption behaviour on surface of mild steel for each studied inhibitor results the Langmuir adsorption isotherm. Surface conduct of mild steel also designed through the SEM and energy dispersive X-ray (EDX) analysis and concludes that there is evolution of inhibitive film of APOT and MPOT on the surface of mild steel.
