Impact of cultural management from the government
Authors: Escudero Sánchez Carlos Leonel
Published: April 2023

The impact of cultural management entails modifying models, patterns and assumptions of a person or a team that guides a cultural process in a public or private institution, the principles and values of the managers, believe in their actions at the time of execution, creating an impact on society with the activities generated, the political influence of the rulers, giving guidelines to the managers, to execute different cultural activities. The strategies to be created by cultural management must express the power to implement instruments such as the training of creators, audiences and mediators; cultural dissemination, and support for artistic creation. Cultural management discovers a harmony within any other management that is effectively executed in society and achieves its respective purposes; cultural policy has the competence to regulate and legitimize the cultural responsibility that is intended to be executed from the public sector, incorporating cultural development as a component of the State's public services, linked to other public services. The governmental cultural management is executed through projects within established cultural programs, it represents an element of analysis to value the position in which cultural management is executed, where there must be related competences with the knowledge of the administrative development in culture.
COMFORT WOMEN SURVIVING PANDEMICS: FROM ERASURE TO EMBODIED HOPE TOWARDS A FEMINIST-POSTCOLONIAL THEOLOGY OF RADICAL HOSPITALITY
Authors: Bong S.A.
Published: April 2023

The article accords epistemic privilege to comfort women as embodiment of the perversion of hospitality. It draws aparallelism between their surviving the pandemics of World War II as forcibly recruited sex slaves and COVID-19.Through their lived experience as survivors of pandemics, a feminist-postcolonial theology of radical hospitality firstcritiques biblical narratives of men’s hospitality to men. The parallel stories of Lot’s offer of his virgin daughters (Gen. 19)and the Levite’s offer of his concubine (Judges 19) expose, first, the hierarchisation of male guests over women, asproperty of men, and secondly, the inviolable creed of hospitality conferred on men by men, that is sustained by the cultural code that marks women’s bodies as violable. Secondly, the article argues that extending hospitality to comfort women (for example, war reparations) goes beyond the “law of ekstasis”, as touted in Fratelli Tutti, as comfort women themselves embody love, reciprocity, and inclusion.
WE INTER-ARE: THE PANDEMIC CHALLENGE REDEFINING HUMANS AND COMMUNITIES
Authors: Abraham K.
Published: April 2023

The COVID-19 pandemic calls for a critical introspection into our way of being human in relation to other forms of life on this planet. Given that social hierarchies attribute higher and lower status to human beings based on their race, class, caste and gender identity, and legitimise the exploitation of other human beings and the earth, re-thinking our hierarchical positioning as “masters” of this universe becomes imperative. In this context, ecofeminist reconstruction of relationality is projected as a corrective, as it focuses on linking relationships instead of ranking relationships. In addition, the mystical notion “We Inter-Are”, shared by the visionary Buddhist sage Thich Nhat Hanh, is proposed as a key for growing into a consciousness of inter-relationality with other beings on this planet, as it opens us to the infinite mystery of the deeper relatedness of all forms of life. Viewed from this perspective, the pandemic can become a defining momentin the evolutionary story of human beings.
PANDEMIC OASIS: POPULAR RELIGIOSITIES AS WOMEN’S LIFE-GIVING COMMUNITAS
Authors: Chan K.F.
Published: April 2023

This article argues and explores how popular Catholic piety can serve as an agent to create life-giving communitas forwomen in Macao, China. This research uses the narratives of six Catholic women about how their immersion in various public and private devotional practices creates solidarity and communities that are inclusive, empowering, and nurturing during the outbreak of COVID-19. Besides petitioning their long-lasting devotional images such as St Roch and Our Lady of Fatima, women learn and move on to a new model of online and live stream religious response and ritual innovations at the time of coronavirus in Macao. The digitisation of gathering strengthens the global connection among women to the rest of the world, shapinga new form of devotional culture and community ties that are not necessarily institutionalised. Devotional practices act as a spiritual oasis, personally and communally, for women coming together and bring hope, strength, and consolation to this unprecedented time.
Automatic assignment of diagnosis codes to free-form text medical note
Authors: Strydom Stefan , Dreyer Andrei Michael , van der Merwe Brink
Published: April 2023

International Classification of Disease (ICD) coding plays a significant role in classify-ing morbidity and mortality rates. Currently, ICD codes are assigned to a patient’s medical record by hand by medical practitioners or specialist clinical coders. This practice is prone to errors, and training skilled clinical coders requires time and human resources. Automatic prediction of ICD codes can help alleviate this burden. In this paper, we propose a transformer-based architecture with label-wise attention for predicting ICD codes on a medical dataset. The transformer model is first pre-trained from scratch on a medical dataset. Once this is done, the pre-trained model is used to generate representations of the tokens in the clinical documents, which are fed into the label-wise attention layer. Finally, the outputs from the label-wise attention layer are fed into a feed-forward neural network to predict appropriate ICD codes for the input document. We evaluate our model using hospital discharge summaries and their corresponding ICD-9 codes from the MIMIC-III dataset. Our experimental results show that our transformer model outperforms all previous models in terms of micro-F1 for the full label set from the MIMIC-III dataset. This is also the first successful application of a pre-trained transformer architecture to the auto-coding problem on the full MIMIC-III dataset.
Cost-Effective Scheduling in Fog Computing: An Environment Based on Modified PROMETHEE Technique
Authors: Varshney Shefali , Sandhu Rajinder , Gupta P. K.
Published: April 2023

With the rising use of Internet of Things (IoT)-enabled devices, there is a significant increase in the use of smart applications that provide their response in real time. This rising demand imposes many issues such as scheduling, cost, overloading of servers, etc. To overcome these, a cost-effective scheduling technique has been proposed for the allocation of smart applications. The aim of this paper is to provide better profit by the Fog environment and minimize the cost of smart applications from the user end. The proposed framework has been evaluated with the help of a test bed containing four analysis phases and is compared on the basis of five metrics- average allocation time, average profit by the Fog environment, average cost of smart applications, resource utilization and number of applications run within given latency. The proposed framework performs better under all the provided metrics.

Au moment où la pétition « Santé unie », lancée en novembre 2053, est sur le point de recueillir le nombre de voix nécessaire pour créer une assemblée citoyenne délibérative (ACD), il nous a paru intéressant de faire dialoguer deux professionnels de la santé reconnus : Alba Martin-Diop, soignante médicale, et Karim Puig, prévenant mutualiste.
Quand les grands ensembles deviennent des écoquartiers inégalitaires et normatifs à la périphérie des métropoles
Authors: Roudil Nadine
Published: April 2023

Le registre environnemental et énergétique mobilisé, en France, dans les quartiers du Nouveau programme national de renouvellement urbain ( npnru ) apparaît comme un outil de transformation spatiale des grands ensembles en écoquartiers aussi bien que comme un argument de gouvernement des conduites des populations les plus précaires qui y vivent. Les rénovations urbaines engagées à la cité de la Muette, à Garges-lès-Gonesse, et à la cité de la Duchère, à Lyon, soulignent les principes sur lesquels se fonde et s’expérimente une distinction entre « bons » et « mauvais » habitants de la ville durable. Dans les deux écoquartiers étudiés, le repeuplement a été, en vingt ans, générateur d’inégalités sociales alors que le caractère durable de la transformation des grands ensembles prône un modèle d’urbanisme vertueux. Les catégories populaires y connaissent une éviction progressive, chassées par des logiques immobilières auxquelles elles ne peuvent prendre part.
Les figures du militantisme environnemental périurbain. Un engagement, plusieurs logiques d’action
Authors: Dupuit Elodie
Published: April 2023

L’engagement dans le périurbain est le plus souvent réduit à des causes défensives et est, ce faisant, présenté comme éloigné de l’écologie. Ainsi, les dynamiques collectives en faveur de l’environnement dans ces espaces demeurent un objet peu étudié. En particulier, les logiques d’action des militants écologistes périurbains restent méconnues. Pourtant, ces mobilisations constituent un lieu d’engagement important pour les classes moyennes et populaires résidant dans ces espaces. Cet article s’appuie sur une enquête ethnographique menée au sein de deux associations de défense de l’environnement, situées dans le quadrant sud-est du périurbain lyonnais, et qui se mobilisent, entre autres, pour le développement du transport en vélo au quotidien. Une typologie qui distingue cinq profils de militants rend compte de leurs caractéristiques sociales ainsi que des raisons de leur engagement.
Le climat de la France au XXI ème siècle
Authors: Jouzel Jean , Planton Serge
Published: April 2023

Les éléments scientifiques caractérisant le climat et son évolution sont commentés et analysés pour faire ressortir les éléments clés au fondement de l’action publique en matière d’adaptation aux effets du changement climatique. La mise en relation de ces éléments d’ordre physique et d’ordre biologique avec certaines activités humaines montre des dépendances dont le traitement devient nécessaire. La mise en perspective des effets pour le territoire national avec quelques repères clés au niveau mondial permet en outre de situer l’enjeu pour la France dans un contexte global. Enfin, la mise en perspective des conclusions du 5 e  rapport d’évaluation du GIEC avec les avancées portées par le 6 e  cycle montre l’évolution des connaissances en matière de chaîne de causalité et de réduction des incertitudes au cours de la dernière décennie. Les différentes composantes explicitées donnent à voir le socle de connaissances en constante consolidation pour le bénéfice de l’action climatique.
La protection des enfants : enjeux juridiques et institutionnels (XVIII e -XXI e siècles)
Authors: Becquemin Michèle
Published: April 2023

La politique de protection de l’enfance en France s’inscrit dans une vision humaniste de la société, réalisée sur fond de démocratie sociale. Pour autant, différentes conceptions s’opposent lorsqu’il s’agit de la définir, notamment au regard de la question familiale. Les jeux de pouvoir entre l’Assistance aux enfants, la Justice des mineurs et les institutions privées et associatives caractérisent ce domaine d’action publique que seul l’État parvient à harmoniser lors de périodes propices. Lorsque la démocratie sociale est mise en cause et que les cartes sont rebattues, alors la figure de l’enfant à protéger s’estompe face aux désignations d’autres priorités.

Paraître & masculinité dans le Paris populaire des années 1960 : comment se construisent les garçons « dans le vent » ?
Authors: Revenin Régis
Published: April 2023

À partir d’archives judiciaires de la jeunesse, cet article vise à restituer une parole masculine – rare sur le sujet –, celle de jeunes Parisiens de classes populaires évoquant leurs apparences corporelle et vestimentaire, laissant entrevoir à l’aube des années 1960, dans une société où le paraître et la séduction prennent de plus en plus de place, une nouvelle masculinité qui n’efface pas complètement toutes les normes de genre traditionnelles. Il s’achève sur les rêves d’ascension sociale de ces garçons.
Écouter la présence de l’enfant
Authors: Breton Stéphane
Published: April 2023

La consultation psychothérapeutique de l’enfant est l’occasion d’un dialogue intime qui porte en lui la vulnérabilité, la sensibilité et l’espoir d’un mieux-être à la fois personnel et collectif. De cette alliance thérapeutique singulière, il convient de souligner combien une écoute attentive, ouverte et créative à la présence de l’enfant est nécessaire pour engager un changement durable.
L’enfant politique
Authors: Dalsuet Anne
Published: April 2023

Elizabeth première, Louis XIV, Winston Churchill, Golda Meir, Margaret Thatcher, Angela Merkel, tous les grands hommes politiques ont commencé petits. Et l’on ne peut s’empêcher d’imaginer qu’enfants, la passion politique était déjà en eux, en gestation. Mais si tous les hommes politiques, comme les femmes bien évidemment, ont été enfants, y a-t-il pour autant des enfants politiques? L’expression même d’enfant politique semble relever de l’oxymore exprimant la bizarrerie, l’impossibilité logique et ontologique d’une telle hypothèse. La tradition philosophique, en effet, ne s’est-elle pas constituée par ce geste inaugural de mise à l’écart de l’enfant, de la vie politique ?

Prendre soin d’un enfant, c’est prendre soin de son avenir soit prendre soin de son imagination, de sa capacité à inventer cet avenir. Notre question est la suivante : comment prendre soin de l’imagination, de sorte que cette faculté soit véritablement perçue comme une ressource première pour organiser et structurer le champ des expériences vécues tout au long de la vie ?
La fabrique de l’enfant sauvage
Authors: Taïbi Nadia
Published: April 2023

On ne peut se tenir dans l’enfance. Elle est par définition passage. Ce caractère évanescent est sans doute la cause principale des dangers encourus par les enfants : les adultes savent que « ça va passer ». L’enjeu est donc comment faire passer le sauvage (qui ne peut parler mais dont il faut permettre l’expression) sans doute la solution la plus fine est celle de Rousseau: « faire le moindre mal ».
Une dérobade

Published: April 2023

Ce n’est pas là le récit heureux de l’enfance heureuse, ou supposée l’être, véhiculée qu’elle est par cette propension à la légende et à l’image d’Epinal qui touche et déploie ordinairement ce monde premier. Point de bonheur ici – il est toujours l’affaire des idéalistes –, pas d’insouciance ni de monde merveilleux, mais l’indéterminable surgissement d’un être à partir de ce qu’il n’est pas et qu’il ne sera jamais plus, et qui est appelé, par son Nom, à devenir ce qu’il n’est pas, et à être ce Nom.
Pitié pour la créature !
Authors: Barbati Sabatino
Published: April 2023

Cet article examine les différentes figures de l’enfant dans la pensée de Pasolini. Il remonte le cours du temps, partant des dernières interventions civiles (notamment les Lettres Luthériennes ), pour s’arrêter au recueil La Religion de mon temps (1961), où retentit le cri : pitié pour la créature ! Cette remontée s’apparente à une régression, dont les étapes sont la jeunesse, le fils, l’enfant, la créature.
Some results on the existence and stability of impulsive delayed stochastic differential equations with Poisson jumps
Authors: Gao Dongdong , Kuang Daipeng , Li Jianli
Published: April 2023

This paper is concerned with the existence, uniqueness and exponential stability of mild solutions for a class of impulsive stochastic differential equations driven by Poisson jumps and time-varying delays. Utilizing the successive approximation method, we obtain the criteria of existence and uniqueness of mild solutions for the considered impulsive stochastic differential equations. Then, the exponential stability in the $ p $th moment of the mild solution is also devised for considered equations by establishing an improved impulsive-integral inequality, which improves some known existing ones. Finally, an example and numerical simulations are given to illustrate the efficiency of the obtained theoretical results.
A kind of even order Bernoulli-type operator with bivariate Shepard
Authors: Wu Ruifeng
Published: April 2023

It is known that an efficient method for interpolation of very large scattered data sets is the method of Shepard. Unfortunately, it reproduces only the constants. In this paper, we first generalize an expansion in bivariate even order Bernoulli polynomials for real functions possessing a sufficient number of derivatives. Finally, by combining the known Shepard operator with the even order Bernoulli bivariate operator, we construct a kind of new approximated operator satisfying the higher order polynomial reproducibility. We study this combined operator and give some error bounds in terms of the modulus of continuity of high order and also with Peano's theorem. Numerical comparisons show that this new technique provides the higher degree of accuracy. Furthermore, the advantage of our method is that the algorithm is very simple and easy to implement.
Error estimations of a weak Galerkin finite element method for a linear system of $ \ell\geq 2 $ coupled singularly perturbed reaction-diffusion equations in the energy and balanced norms
Authors: Toprakseven Şuayip , Dinibutun Seza
Published: April 2023

This paper introduces a weak Galerkin ﬁnite element method for a system of $ \ell\geq 2 $ coupled singularly perturbed reaction-diffusion problems. The proposed method is independent of parameter and uses piecewise discontinuous polynomials on interior of each element and constant on the boundary of each element. By the Schur complement technique, the interior unknowns can be locally efficiently eliminated from the resulting linear system, and the degrees of freedom of the proposed method are comparable with the classical FEM. It has been reported that the energy norm is not adequate for singularly perturbed reaction-diffusion problems since it can not efficiently reflect the behaviour of the boundary layer parts when the diffusion coefficient is very small. For the first time, the error estimates in the balanced norm has been presented for a system of coupled singularly perturbed problems when each equation has different parameter. Optimal and uniform error estimates have been established in the energy and balanced norm on an uniform Shishkin mesh. Finally, we carry out various numerical experiments to verify the theoretical findings.
Gesture recognition of continuous wavelet transform and deep convolution attention network
Authors: Liu Xiaoguang , Zhang Mingjin , Wang Jiawei , Wang Xiaodong , Liang Tie , Li Jun , Xiong Peng , Liu Xiuling
Published: April 2023

To solve the problem of missing data features using a deep convolutional neural network (DCNN), this paper proposes an improved gesture recognition method. The method first extracts the time-frequency spectrogram of surface electromyography (sEMG) using the continuous wavelet transform. Then, the Spatial Attention Module (SAM) is introduced to construct the DCNN-SAM model. The residual module is embedded to improve the feature representation of relevant regions, and reduces the problem of missing features. Finally, experiments with 10 different gestures are done for verification. The results validate that the recognition accuracy of the improved method is 96.1%. Compared with the DCNN, the accuracy is improved by about 6 percentage points.

Dopunsko zdravstveno osiguranje i mogući scenariji njegova razvitka u Republici Hrvatskoj
Authors:   Pravni fakultet Sveučilišta u Zagrebu, Zagreb, Hrvatska, Gotovac Viktor
Published: April 2023

Dopunsko zdravstveno osiguranje jedno je od tri dobrovoljna zdravstvena osiguranja uređena Zakonom o dobrovoljnom zdravstvenom osiguranju. Riječ je o osiguranju kojim se osigurava pokriće troškova zdravstvene zaštite iz obveznoga zdravstvenog osiguranja u dijelu u kojem su osigurane osobe obvezne sudjelovati u troškovima zdravstvene zaštite, odnosno u cijeni lijeka. Ovo je osiguranje uvedeno Zakonom o zdravstvenom osiguranju 1993. godine koncepcijski obuhvaćajući današnja dopunska i dodatna dobrovoljna zdravstvena osiguranja te se u razdoblju od gotovo 30 godina nije znatnije sadržajno mijenjalo. Slijedom proteka ovog razdoblja primjene ovim se radom žele razmotriti mogući scenariji i smjerovi razvitka ovog osiguranja u Republici Hrvatskoj.
Neformalno sporazumijevanje nakon započinjanja rasprave u kaznenom postupku: iskustva praktičara i teorijska analiza

Published: April 2023

Zakonom o kaznenom postupku predviđeni su različiti konsenzualni oblici postupanja, uključujući i odredbe čl. 417.a st. 6. i 7. ZKP-a, kojima se ograničavaju ovlasti suda u odmjeravanju kazne za slučaj da se okrivljenik suglasi s kaznenopravnom sankcijom koju je predložio državni odvjetnik. Provedeno istraživanje pokazalo je da se ta odredba u praksi shvaća ekstenzivno, kao oslonac za neformalno sporazumijevanje stranaka prije očitovanja o krivnji, ali i da se i nakon očitovanja o krivnji u praksi nerijetko nastavljaju različiti oblici bilateralnih i trilateralnih dogovaranja o konačnom ishodu kaznenog postupka. U navedenom su istraživanju izloženi i analizirani stavovi i iskustva domaćih pravnih praktičara o toj problematici, s ciljem da se dozna u kojoj su mjeri prisutni i na koji se način u praksi manifestiraju različiti oblici neformalnog sporazumijevanja. Kako bi se dobiveni rezultati bolje razumjeli, u početnom su dijelu rada iznesena teorijska razmatranja o neformalnom sporazumijevanju s aspekta temeljnih načela kaznenog postupka. U tom su dijelu autori iznijeli i argumentirali svoje mišljenje o tome koji su oblici neformalnog sporazumijevanja pravno prihvatljivi i pod kojim uvjetima. U zaključku su rezimirani rezultati istraživanja te se uputilo na određene konceptualne manjkavosti hrvatskog kaznenog procesnog zakonodavstva i prakse.

Published: April 2023

Aukcija je u 21. stoljeću, zahvaljujući razvoju suvremenih informacijskih i komunikacijskih tehnologija, postala znatno češćom i većem krugu subjekata dostupnijom metodom sklapanja ugovora o kupoprodaji sve različitijih vrsta robe, a ne tek umjetnina uz koje se ona tradicionalno vezuje. Gospodarska važnost aukcije popraćena je znatnim brojem djela u ekonomskoj znanosti, a 2020. godine Nobelova nagrada za ekonomiju dodijeljena je ekonomistima Paulu R. Milgromu i Robertu B. Wilsonu upravo za njihov doprinos razvoju ekonomske teorije aukcije i stvaranju inovativnih aukcijskih modela. Za razliku od ekonomske znanosti, pravna znanost ne obiluje djelima koja bi se bavila pravnim aspektima aukcije kao specifične metode sklapanja ugovora o kupoprodaji, a osobito ne takvima koja bi se njome bavila sveobuhvatno i sustavno. Stoga je znanstvena monografija Legal Theory of Auction, autora dr. sc. Kristijana Poljanca s Ekonomskog fakulteta Sveučilišta u Zagrebu, nedavno objavljena na engleskom jeziku u nakladi Routledgea, raritet u svjetskim razmjerima. Znanstvena monografija Legal Theory of Auction rezultat je autorova višegodišnjeg istraživanja provedenog, među ostalim, na Pravnom fakultetu Buchmann u Tel Avivu, Europa-Institutu u Saarbrückenu i Max Planck Institutu za poredbeno i međunarodno privatno pravo u Hamburgu. Ono je svojevrsni nastavak autorova ranijeg istraživanja provedenog tijekom izradbe doktorskog rada Sklapanje ugovora o kupoprodaji putem dražbe, obranjenog 2019. godine na Pravnom fakultetu Sveučilišta u Zagrebu. No, objavljena monografija nije tek prijevod autorova doktorskog rada, već izvorno novo djelo koje u svojem većem dijelu obrađuje pitanja kojima se autor u doktorskom radu nije bavio. U znanstvenoj monografiji Legal Theory of Auction autor razvija opću pravnu teoriju aukcije koja počiva na poredbenopravnom istraživanju aukcijskog prava. Autor predstavlja karakteristične značajke aukcijskih prodaja koje određuju pravni pojam aukcije i donosi sustavnu analizu različitih ugovornih i izvanugovornih obveznopravnih odnosa koji nastaju među raznim sudionicima u povodu i tijekom aukcije. Predmetom monografije su isključivo privatnopravne aukcije, ne i prisilne javne prodaje na dražbama u različitim postupcima pred sudovima i drugim tijelima.

In this chapter, first, the main research contents of touchless palmprint recognition are introduced. Second, the establishment of the CUHKSZ large-scale touchless palmprint dataset will be described in detail. Third, parameter optimization experiments are conducted on the CUHKSZ dataset to observe the scientific problems caused by the increase in data scale. Fourth, the experiment comparing the EER of the most used touchless palmprint recognition algorithms on the large-scale dataset will be performed to provide baselines for future research. Finally, the recognition performances of the three most widely used biometric modals, including palmprint, face, and fingerprint, will be compared on the CUHKSZ dataset, which can demonstrate the advantages of touchless palmprint recognition. In the end of this chapter, future research directions will be put forward.
The Granger Causality of Bahrain Stocks, Bitcoin, and Other Commodity Asset Returns
Authors: Doblas Mark Pabatang , Lagaras Maria Cecilia
Published: April 2023

This study examines the tendency of short-term return spillover across Bahrain stocks, bitcoin, and other commodity assets factoring in the dynamic effect of the COVID-19 pandemic. The study employed vector autoregression (VAR) model using the daily returns of Bahrain All Shares Index, bitcoin, crude oil, and gold futures from January 2018 to March 2022. The results showed a persistent unidirectional short-term spillover of return from the Bahrain stock market to the futures gold market for both the period before and during the pandemic. Moreover, the results also showed that the significant positive shock in the bitcoin returns as granger-caused by the returns of the Bahrain stock market is only during the period before the pandemic. Finally, a significant negative contemporaneous short-term effect on the crude oil market returns can be statistically explained by the shocks in the Bahrain stock market only during the COVID-19 period.
A Systematic Review of Gamification and Its Assessment in EFL Teaching
Authors: Helvich Jakub , Novak Lukas , Mikoska Petr , Hubalovsky Stepan
Published: April 2023

The aim of this study is to examine the satisfaction of EFL teachers with gamification platforms as well as to investigate how EFL teachers perceive gamification and its effects on pupils' motivation and learning outcomes. Five major databases (ERIC, Scopus, WoS, EBSCO, ProQuest) and Google Scholar were used to search for relevant studies. The study followed the PRISMA guidelines and the PICO framework. Inter-rater reliability analyses were performed for both study selection and study quality assessment. Eleven relevant quantitative or mixed studies were identified. The findings indicate that EFL teachers perceived a positive effect of gamification on pupils' motivation and are satisfied with the applicability of gamification platforms. The findings revealed that internet and technology issues and a lack of teachers' skills are the most prominent negative factors when implementing gamification. Further experimental research is needed to provide evidence of the EFL teacher-perceived effectiveness of gamification on learning outcomes.
Remote Sensing Image Segmentation Based on a Novel Gaussian Mixture Model and SURF Algorithm
Authors: Yin Shoulin , Wang Liguo , Wang Qunming , Yang Jinghui , Jiang Man
Published: April 2023

This paper proposes a novel remote sensing image segmentation method based on Gaussian mixture model and SURF algorithm. Firstly, Gaussian mixture model is used for remote sensing image segmentation. Then the surf matching algorithm is adopted for eliminating misidentified areas. The determinant of Hession matrix (DoH) is used to detect key points in the image. The non-maximum suppression method and interpolation operation are utilized to search and locate the extreme points. The maximum likelihood method is used to estimate model parameters. Some remote sensing images in THE DOTA data set are selected for experimental verification, and the results show that the new algorithm has obvious improvement in segmentation effect and efficiency. In the background complex image segmentation, the improved algorithm has more obvious advantages compared than state-of-the-art segmentation methods.
MCAM+CD161− Th17 Subset Expressing CD83 Enhances Tc17 Response in Psoriasis

Recent studies have highlighted the pathogenic roles of IL-17–producing CD8+ T cells (T-cytotoxic 17 [Tc17]) in psoriasis. However, the underlying mechanisms of Tc17 induction remain unclear. In this study, we focused on the pathogenic subsets of Th17 and their mechanism of promotion of Tc17 responses. We determined that the pathogenic Th17-enriched fraction expressed melanoma cell adhesion molecule (MCAM) and CCR6, but not CD161, because this subset produced IL-17A abundantly and the presence of these cells in the peripheral blood of patients has been correlated with the severity of psoriasis. Intriguingly, the serial analysis of gene expression revealed that CCR6+MCAM+CD161−CD4+ T cells displayed the gene profile for adaptive immune responses, including CD83, which is an activator for CD8+ T cells. Coculture assay with or without intercellular contact between CD4+ and CD8+ T cells showed that CCR6+MCAM+CD161−CD4+ T cells induced the proliferation of CD8+ T cells in a CD83-dependent manner. However, the production of IL-17A by CD8+ T cells required exogenous IL-17A, suggesting that intercellular contact via CD83 and the production of IL-17A from activated CD4+ T cells elicit Tc17 responses. Intriguingly, the CD83 expression was enhanced in the presence of IL-15, and CD83+ cells stimulated with IL-1β, IL-23, IL-15, and IL-15Rα did not express FOXP3. Furthermore, CCR6+MCAM+CD161−CD4+ T cells expressing CD83 were increased in the peripheral blood of patients, and the CD83+ Th17-type cells accumulated in the lesional skin of psoriasis. In conclusion, pathogenic MCAM+CD161− Th17 cells may be involved in the Tc17 responses via IL-17A and CD83 in psoriasis.
An unconventional career path for an oral pathologist

Background:

Dental caries is as primeval as humanity, but still, investigations are undergoing regarding the etiopathogenesis behind this multifactorial disease. Genetics is known to play a vital role in the etiology behind dental caries in addition to environmental and socioeconomic factors. Genetic variations like single-nucleotide polymorphisms (SNPs) were extensively studied in the past decade to portray the etiopathogenesis contributing to dental caries.

Aim:

This investigation was undertaken to analyze the ENAM gene SNP rs3796704 with caries susceptibility in ethnic young adult Tamil population of India.

Materials and Methods:

Out of 370 patients included, 215 patients belonged to the high caries group (Decayed, Missing and Filled Tooth [DMFT] ≥2) and 155 patients belonged to the low caries group (DMFT ≤ 1). DNA was extracted from the blood of all the individuals. SNP genotyping was performed utilizing tetra-primer amplification refractory mutation system–polymerase chain reaction with specific primers.

Results:

The genotyping results showed that there were no differences in allelic (P = 0.114) and genotypic frequencies (P = 0.159) between the high caries and low caries groups.

Conclusion:

Future studies can be conducted in larger samples and different ethnicities around the globe to analyze the role played by SNPs of enamel formation genes in cariogenesis.

Published: April 2023

Introduction:

Pattern of invasion (POI) in scoring system of oral squamous cell carcinoma (OSCC) can predict local recurrence and overall survival rate. Argyrophilic nucleolar organizer region (AGNOR) counts are considered to reflect the biosynthetic and nucleolar activity of a cell and thus serve as an indicator of the rapidity of the cell cycle thereby indicating the proliferative index of the tumor. It is implied that higher tumor associated tissue eosinophilia (TATE) showed lesser venous invasion, lymph node metastasis and clinical recurrence. The aim of the study was to assess and evaluate the following criteria's: POI-1 to POI-4 as defined by Bryne et al. in OSCC, proliferative index by AgNOR stain and TATE with carbol chromotrope stain in OSCC, validity of POI by correlating the AgNOR proliferative index and TATE.

Materials and Methods:

Forty samples of formalin fixed paraffin embedded tissue blocks diagnosed of OSCC were taken for the study. Three sections were taken from a single block and then the tissues were stained differently with H & E Stain, AgNOR stain and Carbol chromotrope stain. First section stained with H & E was observed for POI and grading was done according to Bryne's criteria. The second and third sections were stained with AgNOR stain and Carbol chromotrope stain for proliferative index and TATE. One way analysis of variance was used to test the significance.

Results:

Mean AgNORs count increases gradually from type 1 to type 4, depicting the increase in the nucleolar proliferative index of the cells and was statistically significant. In the case of the mean eosinophilic count, type 1 shows the highest mean eosinophilic count and the count shows drastic decrease till type 3 and from type 3 to type 4 the decrease is more gradual and was statistically significant.

Conclusion:

The study validated that POI is a good predictor for prognosis and also can be included in grading OSCC along with routine histopathological criteria.

Published: April 2023

Background:

The prevalence of denture stomatitis has been shown to vary from 15% to 65% in complete denture wearers. In recent years, a number of studies across the globe have investigated the various biological effects of curcumin, curcumin, a polyphenolic compound derived from dietary spice turmeric, possesses diverse pharmacologic effects including anti-inflammatory, antioxidant, antiproliferative and antiangiogenic activities. The aim of this study was to evaluate the efficacy of curcumin local application with common antifungal agent clotrimazole for the treatment of denture stomatitis.

Materials and Methods:

A randomised double-blind clinical trial with approval of institutional ethical committee consisting fifty participants divided into two groups (17 men–33 women) with the clinical signs and symptoms of oral candidiasis. The diagnosis was supported by microbiological cultures. Group A patients were prescribed the clotrimazole and Group B patients were prescribed the curcumin ointment which was dispensed in similar amber coloured bottles. Data were analyzed using Chi-squared tests, Wilcoxon's signed rank sum test and Mann-Whitney test.

Results:

The mean candidal colony counts before treatment in Groups A and Group B were 63.960 and 37.080, respectively. The mean candida colony counts after treatment in both the groups were 14.080 and 3.720, respectively. There was a statistically significant difference between the two groups when mean candida colony counts were calculated before and after treatment. However, intergroup comparison between the two groups considering the mycological eradication showed that there was no statistically significant difference with P = 0.404.

Conclusion:

Topical application of curcumin as a natural ingredient could be an effective agent for the treatment of denture stomatitis as an alternative to regular clotrimazole therapy.
Neutrophil-to-lymphocyte ratio as a prognostic factor in oral squamous cell carcinoma – A single-institutional experience from a developing country
Authors: Mishra Vigyan , Giri Ranjana , Hota Subhranshu , Senapati Urmila , Sahu Subrat Kumar
Published: April 2023

Background:

Cell-mediated inflammatory response, neutrophils, lymphocytes and monocytes are being recognized as an important role in carcinogenesis. Neutrophil-to-lymphocyte ratio (NLR) has been used as an independent prognostic factor in varieties of cancers. NLR can be easily determined from complete blood count, and it could be considered as a simple and inexpensive prognostic marker.

Aim:

In this study, we evaluate the prognostic significance of NLR in patients with oral squamous cell carcinoma (OSCC).

Materials and Methods:

Clinical and epidemiological data of all biopsy-proven nonmetastatic OSCC treated between 2014 and 2018 were taken into consideration. Pretreatment absolute neutrophil and lymphocyte counts were used to get NLR. Using univariate and multivariate analysis, the impact of NLR on overall survival (OS) and progression-free survival (PFS) was investigated.

Results:

A total of 50 patients of OSCC with median pretreatment NLR ratio of 2.52 were identified. Based on the median NLR as a cutoff, patients were classified into two groups, i.e., high NLR and low NLR. Elevated NLR was significantly associated with lymph node metastasis (P = 0.01). Four-year OS and PFS were significantly better for patients with low NLR when compared with high NLR group (51.4% vs. 100%, P = 0.001). Four-year PFS for high and low NLR groups was 38.8% and 87.8% (P = 0.002). Multivariate analysis confirmed that NLR is an independent prognostic factor (P = 0.003).

Conclusion:

Pretreatment NLR provides a simple, cheap and early predictor of outcome in this group of patients. However, an optimal cutoff value of NLR should be determined, for which larger sample size and prospective studies are required.

Authors: Muthu Kavitha , Narayanan Mohan
Published: April 2023

Oral cancer arises as a result of multistep carcinogenic progress from precursor lesion to oral squamous cell carcinoma through collective mutational process occur in the stem cells of mucosal epithelium. The detection of such oral potentially malignant disorders (OPMDs)/cancer in subclinical level will greatly improve the prognosis of a patient. The highly specific and sensitive salivary biomarkers have functioned in detection, prediction, surveillance and therapeutic monitoring of the diseases of interest. The aim of the review is to appraise various salivary biomarkers for the clinical utility in OPMDs. An electronic web-supported search was performed via PubMed, ScienceDirect and Google Scholar search engine since the year 2015–2019. A total of 28 research articles were selected for the review after screening and assessment. The various genomic, transcriptomic, proteomic, metabolomic and miscellaneous markers were analyzed and their characteristics and clinical application in OPMD patients were discussed. miR-21, miR-31, miR-84, H3F3A mRNA + IL-8P, matrix metalloproteinase-9, chemerin, tumor necrosis factor-alpha, cytokeratin-10, ornithine + O-hydroxybenzoate + R5F, 8-hydroxy-2-deoxyguanosine, malondialdehyde, Vitamin E and Vitamin C are identified as potential markers for OPMD patients. Scientifically validated, reliable and economical clinical biomarkers in OPMDs would serve as evidence-based treatment from patient point of view. Further longitudinal studies are needed to verify the accuracy and validate the applicability of these diagnostic/prognostic markers. Saliva has been reported as a valuable noninvasive valuable tool in biomarker identification. Recent advancements in salivary biomarker identification techniques lead to various potential biomarkers with precise outcome. The utilization of these biomarkers for the clinical application in OPMDs depends on the feasibility and personal choice of the clinician.

Authors: Acharya Shivesh , Singh Shruti , Bhatia Sarabjot Kaur
Published: April 2023

Causative linkages of tobacco use with oral potentially malignant disorders and cancers of oral cavity have been studied. Oral squamous cell carcinoma is one of the most common cancers in India. The International Agency for Research on Cancer (IARC) monograph found a significant association between smokeless tobacco (SLT) use and oral cancer. However, only a few limited studies have been represented on the IARC monograph. Published meta-analyses have provided pooled risk estimates for oral cancers caused by tobacco, both on global and regional levels. This systematic review was aimed at summarizing all the available studies exclusively in India by collecting data from PubMed and Medline. Emphasis was laid on cohort and case–control studies, and a few cross-sectional studies for premalignant lesions were also discussed. A significant association was noticed on SLT and premalignant and malignant oral cavity lesions.
