Confrontations , de François Amanecer : une poétique aux confins de l’éthique et du religieux
Authors: Guibal Francis
Published: August 2023

Poète doublé d’un essayiste, François Amanecer se montre soucieux d’inscrire les figures de la créativité artistique dans notre espace d’existence. Francis Guibal le suit ici dans sa présentation d’œuvres diverses qui se confrontent aux tensions d’un psychisme étrangement habité et à la réalité énigmatique d’un tout autre à la proximité insaisissable. Une poétique tend à se dégager, où l’inspiration ne va pas sans cohérence et où la plausibilité de convictions existentielles se nourrit elle-même de l’expérience intime d’une Présence.
Du conflit au dialogue : l’athéisme scientifique en RDA (1963-1990)
Authors: Patzelt Eva
Published: August 2023

La discipline universitaire athéisme scientifique a été présente dans la recherche et l’enseignement supérieur est-allemands pendant près de trois décennies. Entre 1963 et 1968, une chaire lui a été dédiée à l’université d’Iéna, suivie de deux décennies de travaux moins exposés aux regards mais non moindres. Les représentants de cette discipline, des philosophes marxistes et membres du parti au pouvoir, étaient les principaux experts du régime sur les phénomènes religieux et espéraient bien exercer une influence sur la politique et la propagande. Dans les années 1980, ils furent les partenaires d’un dialogue que certains milieux chrétiens, notamment protestants, appelaient de leurs vœux. Parmi leurs travaux scientifiques, ceux de sociologie religieuse ont fait l’objet de nombreuses reprises et citations, y compris par des auteurs occidentaux et contemporains.
Les femmes dans les sciences de l’homme : obstacles systémiques et stratégies de contournement (France, xix e - xx e siècle
Authors: Fabre Mélanie , Linos Marie , Elmer Margot
Published: August 2023

Cet article propose une mise au point historiographique sur la place des femmes dans les sciences de l’homme au xix e et au xx e  siècles en suggérant des pistes à suivre pour enrichir les recherches déjà menées sur ce sujet, dont il souligne l’actualité. Partant du constat de la faible présence des femmes dans l’histoire des sciences humaines et sociales, ce texte expose les obstacles systémiques qu’elles ont rencontrés en France, en insistant notamment sur les difficultés de formation que ces dernières ont connues, l’enseignement supérieur leur ayant longtemps été très peu accessible. Ce travail revient en outre sur le parcours de quelques pionnières qui réussirent à contourner ces obstacles pour entreprendre des carrières de chercheuses dans les disciplines très conservatrices qu’étaient sur ce point la philosophie et l’histoire. Cet article se penche enfin sur la contribution aux sciences sociales apportée par les femmes engagées dans les milieux associatifs consacrés à l’action sociale en analysant la manière dont ces amatrices contribuèrent à la constitution d’un savoir empirique sur les classes populaires au tournant du xix e  et du xx e siècle.
Les soubassements émotionnels et religieux du populisme
Authors: Illouz Eva , Sarthou-Lajus Nathalie
Published: August 2023

En Israël, comme dans d’autres régions du monde, le populisme entretient un rapport étroit avec la religion, notamment à travers la mobilisation d’émotions qui ont une forte coloration religieuse, comme la peur ou le dégoût. En sociologue des émotions, Eva Illouz montre comment, dans les mouvements populistes, la dimension religieuse de ces émotions renforce les frontières entre les groupes auxquels on appartient, principalement en Israël.
En quête de théologie africaine
Authors: Katchekpele Léonard Amossou
Published: August 2023

En Afrique, le christianisme est associé à la colonisation. Quel peut être son avenir sur un continent devenu indépendant ? Un débat porte sur les religions traditionnelles : sont-elles (seulement) des préparations évangéliques ? En place de comparaisons, il vaut mieux aborder la question sous l’angle de la rencontre et de l’hospitalité. Un Dieu étranger peut être accueilli.
Capacité d’évolution des réseaux logistiques en période de crise
Authors: Jouve Nicolas , Blanquart Corinne , Vaillant Ludovic
Published: August 2023

La crise du COVID-19, inédite par son caractère global et sa durée, a mis en lumière les points faibles des réseaux logistiques, remettant sur le devant de la scène les recommandations pour une vulnérabilité moindre de ces réseaux. L’objectif de cet article est alors de questionner l’adaptabilité des organisations logistiques, leur capacité à évoluer vers de nouvelles façons de faire pour faire face à l’incertitude inhérente aux crises. L’article s’appuie sur les travaux de Burmeister (2000) qui classe les organisations logistiques et de transport (OLT) en « familles logistiques ». Dans chacune des quatre familles, la coordination entre les professionnels est structurée par une valeur-cadre, référence partagée par les acteurs de la famille considérée pour faire leurs choix. Partant de là, la question soulevée est de savoir si la crise du COVID-19 a conduit à un glissement de certaines relations entre professionnels d’une famille vers une autre, autrement dit à un changement de valeur-cadre. L’enquête sur laquelle s’appuie cette recherche montre que, si les acteurs d’une famille logistique donnée adaptent leurs stratégies logistiques et de transport aux situations de crise, ces stratégies découlent toujours de la même valeur-cadre. Les familles logistiques résistent donc à la crise. Ainsi, les relations entre ces acteurs, les choix qu’ils opèrent, restent guidés par les valeurs-cadres qui régissaient leurs rapports avant la crise. Les modalités de coordination entre les acteurs des réseaux logistiques ne changent pas en période de crise. Cette permanence de la structure de coordination ne constitue pas pour autant une limite au changement profond des réseaux logistiques, qui restent adaptables.
De l’identité à la singularité
Authors: Marie Pierre
Published: August 2023

La psychanalyse a fait voler en éclats la prétention des hommes de s’égaler à une identité : nom, nation, orientation sexuelle, patrimoine, etc., en montrant que nous ne sommes à chaque instant que ce que nous exprimons par notre manière d’être actuelle – Montaigne nous en avait déjà informés.
Identité et identification chez Lacan : la question queer
Authors: Zafiropoulos Markos
Published: August 2023

La question queer et les débats qu’elle suscite dans le champ psychanalytique, comme les échanges avec la théorie du genre exigent de revenir à la théorie de l’identité qui brille par son absence dans le champ freudien. D’où la nécessité de désigner tout ce qui motive les illusions identitaires du point de vue de Lacan : la prégnance du moi et du fantasme qui sont précisément deux formations dont il convient d’affaiblir la puissance par l’expérience psychanalytique avec les névrosés qu’ils soient queer ou pas.
Quelle écoute psychanalytique auprès d’adolescents s’interrogeant sur leur identité sexuée
Authors: Perret Anne
Published: August 2023

Il s’agit ici de tenter de préciser quel type d’écoute psychanalytique serait envisageable avec les adolescentes en interrogation sur leur identité sexuée. Il s’agira de s’attacher à préciser de qui ou de quoi cette clinique, qui se situe au carrefour du subjectif et du social et que l’on peut qualifier de clinique du pubertaire, est le nom et à en entendre la singularité. Nous insisterons sur la spécularité du lien inhérente à la question du féminin chez ces jeunes filles, sur la trajectoire qui mène du maternel au féminin, et sur le refus du féminin paraissant central dans cette clinique.
« Programmé mais libre »
Authors: Munnich Arnold
Published: August 2023

L’auteur, généticien de renom, explore un apparent paradoxe « déterminé mais libre ». En considérant la situation génétique des « vrais » jumeaux, il démontre que chaque jumeau n’est pas un clone mais un être singulier. En effet, après la fécondation, interviennent toute une série d’étapes qui sont autant de points de divergence possibles entre vrais jumeaux, dont la répartition aléatoire de l’ adn mitochondrial au cours du développement embryonnaire, l’inactivation du chromosome  x , et l’instabilité mitotique. Enfin, du fait de la possible survenue de mutations, expansions ou contractions de l’ adn génomique codant et non codant lors des divisions cellulaires dans les tissus en développement (mutations somatiques), une mère indemne de toute maladie génétique peut donner naissance à de vrais jumeaux dont l’un – et pas l’autre – présentera une malformation, une fragilité osseuse, un cancer ou une maladie neurologique. Ces recherches préviennent contre toute tentation de prédire à partir de diagnostic anténatal ce qu’il en sera du devenir somatique du sujet. L’incertitude pronostique ainsi démontrée comme résultat de la complexité de la connaissance scientifique en génétique ne peut qu’inciter à un accueil du singulier dans les consultations en binômes associant un(e) généticien(e) et un(e) psychanalyste.
Le recours aux experts
Authors: Audétat Marc , Joseph Claude , Kaufmann Alain , Leresche Jean-Philippe
Published: August 2023

Cet article se penche sur le rôle dans l’espace public helvétique des institutions en charge d’organiser une évaluation éthique ou participative des enjeux scientifiques et techniques. Centré sur deux controverses dans un contexte de démocratie semidirecte, il tire un bilan des différentes formes d’exercice de l’expertise en public et de mobilisation des acteurs. En témoignant d’une négociation des incertitudes tout au long de processus d’apprentissage, les risques évoqués déstabilisent le schéma linéaire de l’expertise. Dans cette perspective, le pluralisme de l’évaluation des risques apparaît comme une variable de la régulation des rapports entre expertise et société. Les conclusions mettent en avant un modèle d’appréciation de la démo cratie technique dans les controverses.
Le recours aux experts
Authors: Alam Thomas
Published: August 2023

L’article interroge la production d’expertise et son articulation avec la décision publique dans le domaine des ESST à partir d’un double éclairage comparé (diachronique et synchronique) des situations française et britannique. Cette approche permet d’appréhender de manière contrastée le rôle de l’expertise scientifique en situation de crise et d’incertitude, son caractère contraignant pour le décideur, tout en soulignant l’absence d’universalité dans les nouveaux principes directeurs de ce secteur d’action publique. La comparaison permet en effet de mieux saisir les spécificités institutionnelles et culturelles qui structurent fondamentalement ces dynamiques tout en restant peu visibles dans le cadre d’une approche monogra phique.
Effect of Quarantine on Body Weight Among Residents of Assisted Living Facilities During the COVID-19 Pandemic
Authors: Beck Maureen Stabile , Bi Shuyan , Atai Faith D. , Rianon Nahid J.
Published: August 2023

Assisted living facility (ALF) residents are at greater risk of declining health and death from coronavirus disease 2019 (COVID-19) due to advanced age, frailty, chronic conditions, and transmission prevention methods. One method, room quarantine, can lead to isolation and potential weight changes. Continuous room quarantine was mandated by the state for all nursing home and ALF residents. The objective of the current study was to determine the degree and significance of weight loss during quarantine through retrospective chart review and use these findings to guide a quality improvement project. Pre–and post–COVID-19 weights were compared for 53 house call program residents. Descriptive statistics and logistic regression were used. This small convenience sample demonstrated significant weight loss for 40% of ALF residents quarantined during the COVID-19 pandemic. Males showed a greater risk of significant weight loss. Weight loss of 5% in 1 month is considered problematic in older adults. As quarantine measures continue to be used for COVID-19 outbreaks, weight changes, particularly among males, need to be monitored and reported for intervention. [

Desigualdad y movilidad de renta: la ‘curva del Gran Gatsby’ en 46 provincias españolas
Authors: Carabaña Julio
Published: August 2023

Con datos del Atlas de Oportunidades, el artículo examina las diferencias de movilidad de ingresos entre 46 provincias españolas, la relación entre desigualdad y movilidad relativa (la llamada “curva del Gran Gatsby”) y absoluta y la asociación de la movilidad con otras variables, como el nivel medio de renta, el paro o el nivel educativo, todo siguiendo un trabajo de Chetty et al. (2014). Encuentra una correlación de en torno a 0,5 entre movilidad absoluta y movilidad relativa; no encuentra relación de la movilidad relativa con la desigualdad, pero sí de la movilidad absoluta, que además se asocia negativamente con la tasa de paro. Como secuencia causal más verosímil se propone que la prosperidad de las provincias determina su movilidad absoluta, y esta la relativa. Esta propuesta lleva a la cuestión, que queda abierta, de qué unidades territoriales influyen en la movilidad y por qué.
El efecto electoral de la coalición de la izquierda radical española para las elecciones generales de 2016. Un análisis cuasiexperimental con datos de encuestas
Authors: Gago Rivas Víctor
Published: August 2023

Los efectos de las coaliciones electorales en el comportamiento electoral continúan siendo un terreno inexplorado en la sociología política. No existen apenas estudios que analicen los efectos del tránsito del enfrentamiento electoral a la colaboración preelectoral. Nuestra investigación se centra en el caso español, analizando el efecto que produjo la formalización de la coalición entre Izquierda Unida y Podemos para las elecciones generales de 2016, tras competir en las de 2015. Aprovechando que la coalición se anunció mientras se realizaba una encuesta preelectoral, estudiamos, a través de un diseño cuasiexperimental, el efecto de este anuncio. También analizamos los factores que estarían detrás de la decisión de no votar al partido de referencia en coalición. Encontramos que fueron los votantes del socio minoritario quienes desertaron de seguir a su partido en coalición y la importancia que, en esta decisión, tiene la valoración de los líderes de la coalición, la simpatía partidista y la cercanía política al partido retador.
RENAL CYST DETECTION IN ABDOMINAL MRI IMAGES USING DEEP LEARNING SEGMENTATION
Authors: Sowmiya S. , Snehalatha U. , Murugan Jayanth
Published: August 2023

Renal cysts are categorized as simple cysts and complex cysts. Simple cysts are harmless and complicated cysts are cancerous and leading to a dangerous situation. The study aims to implement a deep learning-based segmentation that uses the Renal images to segment the cyst, detecting the size of the cyst and assessing the state of cyst from the infected renal image. The automated method for segmenting renal cysts from MRI abdominal images is based on a U-net algorithm. The deep learning-based segmentation like U-net algorithm segmented the renal cyst. The characteristics of the segmented cyst were analyzed using the Statistical features extracted using GLCM algorithm. The machine learning classification is performed using the extracted GLCM features. Three machine learning classifiers such as Naïve Bayes, Hoeffding Tree and SVM are used in the proposed study. Naive Bayes and Hoeffding Tree achieved the highest accuracy of 98%. The SVM classifier achieved 96% of accuracy. This study proposed a new system to diagnose the renal cyst from MRI abdomen images. Our study focused on cyst segmentation, size detection, feature extraction and classification. The three-classification method suits best for classifying the renal cyst. Naïve Bayes and Hoeffding Tree classifier achieved the highest accuracy. The diameter of cyst size is measured using the blobs analysis method to predict the renal cyst at an earlier stage. Hence, the deep learning-based segmentation performed well in segmenting the renal cyst and the three classifiers achieved the highest accuracy, above 95%.
OPTIMIZED RADIOMICS-BASED MACHINE LEARNING APPROACH FOR LUNG CANCER SUBTYPE CLASSIFICATION
Authors: Jacob Chinnu , Gopakumar C. , Nazarudeen Fathima
Published: August 2023

Lung cancer is a major global health concern and a leading cause of cancer-related deaths. Accurate diagnosis and treatment of lung cancer are crucial for improving patient outcomes. Subtyping lung cancer provides essential information about its molecular characteristics, clinical behavior, and prognosis, thereby guiding treatment planning. Radiomics, a novel discipline, offers a promising approach to characterize the tumor microenvironment by extracting quantitative imaging features from medical images. Radiomics aims to comprehensively and non- invasively characterize tumors and their microenvironment, enabling the identification of tumor subtypes, prediction of therapy response, and enhancement of patient outcomes. This study evaluates the effectiveness of a Particle Swarm Optimization-Random Forest (PSO-RF) classifier for subtype categorization of lung cancer based on radiomics using computed tomography (CT) images. The study utilizes three datasets, extracting 1093 radiomic features and reducing them to 20 significant features through extra tree feature selection. Optimized parameters of the PSO-RF classifier are determined using 10-fold cross-validation and compared to traditional machine learning classifiers and reported works. Results demonstrate that the PSO-RF classifier outperforms other methods, achieving an accuracy of 92%, precision of 92.5%, recall of 92%, and [Formula: see text] 1-score of 0.92 in the Lung1 dataset. Training on Dataset 3 and validating the Lung3 dataset confirm the generalizability of the model, yielding an accuracy of 87% and an AUC of 0.91 across diverse scenarios. These findings highlight the efficacy of radiomics in identifying lung cancer subtypes and demonstrate the potential of the PSO-RF classifier. The incorporation of radiomics into clinical practice has the potential to greatly improve patient outcomes by customizing treatment approaches according to unique tumor characteristics. The demonstrated effectiveness of the PSO-RF classifier makes it a valuable resource for diagnosing and categorizing different subtypes of lung cancer.
Enabling Transformational Complexity Leadership in Education
Authors: Peters Beryl , Beyak Timothy Shawn
Published: August 2023

This chapter answers calls for a transformational, distributed, action-centered approach to leadership to engage with, problematize, and take action to address complexities and challenges facing education. Complexity leadership theory is informed by complexity theory, grounded in complex adaptive systems, and characterized by multi-level, dynamic interactions, and emergence. The authors describe ways that their formal and informal leadership roles as consultant, administrator, academic, and teacher-leader, illustrate and illuminate the potential of complexity leadership for the education system. They explore this potential as embedded in the context of an action research project enacted across all levels of the education system. These leadership practices may motivate and encourage formal and informal leaders to consider purposeful, planned ways to enable transformative change within complex adaptive systems.
The Impact of Transformational Leadership Style on Educational Stakeholders
Authors: Reid Kareen
Published: August 2023

Leadership is a concept applicable in all fields and beneficial to all. The benefits individuals receive from leaders heavily depend on the leadership styles that leaders use. Hackett stated that leadership is the most critical competency for any organization that aims to develop its people. School leadership is a salient part of students learning in all educational institutions, and as such, the type of leadership that is practiced in schools is crucial to the teaching, classroom procedures, and the school environment as these impact student performance. Bass states that transformational leadership is how leaders' behaviours impact their followers. Bass and Avolio stated that the transformational leadership style allows individuals to feel valued and gives them a sense of purpose, respect, and trust in their leaders. This chapter focuses on the impact of transformational leadership styles on educational stakeholders.
Inclusive Leadership in the Amish Community
Authors: Keim Charles , Keim Hannah
Published: August 2023

This chapter examines the leadership practiced by the Old Order Amish located in the Holmes and Wayne counties of Ohio, USA. Contrary to popular stereotypes, this community is vibrant and growing, and it is notable for the strong sense of belonging among members. The leadership of the Amish is investigated to see how this sense of belonging is cultivated. The chapter outlines the role of leadership, how leaders are chosen, and leadership's response to the encroachment of technology. Leaders play a critical role in creating a sense of belonging within the community, and the way in which they do this holds practical lessons for how leaders can create a sense of belonging in their secular organizations.

Authors: Duklaska Alma , Ferrazza Alessandro , Cantafio Giuseppe Umberto
Published: August 2023

The aim of the study was to find the influence of leadership on employee motivation and performance in the private sector in Albania. The project used a case study as the research design. A questionnaire and semi-structured interviews were used as the primary means of data collection to gain an understanding of how employees form their opinions about the Agna Group. Agna Group employees were selected to meet the target demographic and a random sample of 112 employees was selected for this study. The study revealed that motivational variables such as management, pay, work environment, perception of organizational support, training, recognition, and rewards influence employees' motivation levels and job satisfaction. The study showed that Agna Group employees had a good relationship between management and employee performance and productivity, but it had no effect on talent prevention. The study results can be useful for employers and employees to increase awareness of the aspects that lead to high levels of motivation and job satisfaction.

Published: August 2023

Between 2017 and 2021, the RISE model (route of innovation and business sustainability) structured by the authors of this chapter and Ean University colleagues, has been applied in 126 organizations of different sizes and economic sectors in Colombia. This model is composed of nine factors (innovation, sustainable production, leadership and strategic management, collaborative processes, organizational culture, recognition, new markets, technology, and financial indicators). Four dimensions are analyzed for each factor and in turn, these dimensions are described in 48 variables, among which is happiness at work. The objective of this chapter is to present the analysis of the variables that best explain happiness at work in Colombian companies. The data of the 106 organizations were processed with the statistical package Statgraphic centurión XVI, using factorial analysis using multiple regression, and three variables explain between 46.95% and 48.45% of the managerial decision to strengthen happiness at work to generate a harmonious organizational culture.
The Intersection of Social Entrepreneurship, Sustainability, and Environmental Public Health
Authors: Richardson Kevin , Burrell Darrell Norman
Published: August 2023

Social entrepreneurship and sustainability are two important concepts that have gained increasing attention in recent years. Social entrepreneurship refers to the process of creating new ventures that address social problems and generate social value. Sustainability, on the other hand, refers to the ability of a system or process to maintain ecological, economic, and social well-being over time. The intersection of social entrepreneurship and sustainability has the potential to drive positive change in society by promoting environmentally sustainable practices, addressing social problems, and creating sustainable business models. In this chapter, the authors explore the intersection of social entrepreneurship and sustainability, with a focus on the contributions of social entrepreneurship to sustainability and environmental public health.
The Case for the Chief Strategic Transformational Officer
Authors: Cleveland Simon , Cleveland Marisa
Published: August 2023

Transformation leaders are the relationship builders and change champions in their organizations. To succeed in these roles, such leaders require reskilling and upskilling on specific key performance indicators and techniques to determine issues and corrective actions, the use of data gathering, analysis, as well as data-based decision making. Moreover, as strategists, transformation leaders improve organizational learning; however, to accomplish this, they need to create a shared vision, team leading and systems thinking approach, as well as promoting action learning through problem solving and build a learning culture in the organization. The goal of this chapter is to examine these roles and propose an approach to solve the overarching theme of the study – the need for the establishment of a Chief Transformation Officer at the C-Suit level who would be involved in facilitating change initiatives, which emerge from the factors explored in the literature review.
Assessing the Risk of Material Damage of Building Construction of High-Rise Rooms Due to Fires and Emergencies
Authors: Koval Roman , Yemelyanenko Sergiy , Kuzyk Andriy , Starodub Yuriy
Published: August 2023

In recent years, in connection with numerous incidents of fires occurring in hotels, many studies have been conducted on risk management issues, as well as actions in emergencies. Research has often been limited to incident analysis rather than addressing how to manage fire safety to minimize risks and did not sufficiently take into account the features of the construction of the hotel building and the characteristics of materials. The existing state of management and regulation of material damage risks from fires and emergencies does not fully take into account the approaches and means for their minimization, in particular in hotels. There is an increasing need for the use of assessment methods that will help in the performance of risk management functions. There is a need to find effective mechanisms for assessing the risks of material damage of building construction and materials of high-rise rooms from fires and emergencies. Fires in public sites on the example of hotels have been taken for research. There is an increasing need for the use of assessment methods that will help in the performance of material loss risk management functions. During the period of martial law, the method of assessing material damage to the building presented in the article can be used to assess material damage from destruction and fires for future compensation. With the help of this method, it is possible to estimate probable material damage from fires and emergencies, which will allow them to be used in supervisory and preventive activities and the insurance industry. Thus, fires in hotels cause significant material damage, and recently, as statistics show, also human losses. In hotels, it is important to ensure the protection of the building, premises and people from fire. Therefore, the issue of assessing fire risks is currently relevant. Fire risk assessment is an important part of fire science and safety engineering.

It is proposed to apply the method of preventing crisis situations (on the example of railway transport) for each systematization parameter in the developed classifier.
Axisymmetric Bending of Circular Plates on a Variable Elastic Base
Authors: Surianinov Mykola , Krutii Yurii , Klymenko Oleksiy , Vakulenko Vladyslav , Rudakov Serhii
Published: August 2023

An algorithm of direct integration method for calculation of annular plates lying on elastic Winkler base with variable bedding coefficient under the action of transverse load is proposed. To verify the results obtained by the proposed method, the finite element method implemented in PC LIRA-SAPR is used. Two examples of calculations are considered. Analysis of the results shows that the values of deflections practically coincide in calculations of a circular plate by the author's method and by the finite-element method, and discrepancy between the values of bending moments reaches 9.3 %. Moreover, the discrepancy in deflections appears only in the fourth (and sometimes even in the fifth) decimal place. It is noted that the method of direct integration has demonstrated very high accuracy in solving numerous problems of deformable solid mechanics that have exact solutions. The discrepancy in the values of bending moments obtained here is related to the semi-automatic breakdown of the finite-element mesh in PC LIRA-SAPR. This statement is based on the fact that when the mesh is thickened in the circumferential direction, the results obtained by the two methods in determining the radial and circumferential bending moments converge considerably.
Comparison of Settlements of Buildings on Soil-Cement Soil Bases Determined Analytically and by Long-Term Geodetic Observations
Authors: Vynnykov Yuriy , Razdui Roman
Published: August 2023

Comparative results of settlements of soil-cement soil bases of multi-story residential buildings determined by the methods of linear soil mechanics, finite element modeling in a planar (2D) and spatial (3D) setting using an elastic-plastic soil model, as well as long-term (over ten years) data of geodetic observations of natural objects are given. The object of this work was to evaluate the reliability of various methods of predicting the settlements of soil-cement soil bases of buildings on strip foundations in the presence of weak soils within the compressible soil thickness and reinforcement of the massif to a depth smaller than the width of the foundations. It was established that in the presence of layers of weak soils within the compressible soil thickness under strip foundations and reinforcement of the massif to a depth less than their width the actual settlements of such soil base exceeds the values allowed by the norms. The scientific novelty of the work is it was determined in the first time that under these conditions the methods of linear soil mechanics underestimate the calculated settlements by more than two times compared to their actual values. On the other hand, the high reliability of the use of mathematical modeling methods using the elastic-plastic soil model has been proven.
Subsidence of Existing Buildings from the Impact of New Construction

Published: August 2023

The article describes the methodology and results of geodetic observations of additional subsidence of two residential buildings with strip foundations on moist loess soil. Next to them, a pit was dug for the new building, which was deeper than the level of the soles of these foundations. The authors proved that of arranging the pit fence ensured the fulfillment of regulatory requirements for not exceeding the maximum allowable values of foundations of existing buildings by additional subsidence. The technology provided for the construction of a pit enclosure with sheet piling (I-beam No. 30) with a step of 1 m, with timber lagging between them. At the same time, the phasing of soil extraction in the initial stages under the protection of a soil berm was maintained. Then they installed the capping beam, struts, rakers and gradually raised the floor and outer wall of the parking lot of the new building. Sufficient convergence of the simulation results in the plane condition using the finite element method and field studies was determined. An elastic-plastic soil model of the "basement - foundations of an existing building - pit enclosure" system was used for modeling.
Non-Linear Migrations and Urban Resilience
Authors: Mou Mayisha Tahsin , Rahman Md Mahmudur , Mim Nusrat  Jahan
Published: August 2023

This paper looks at migrations as an inherent component of urban resilience and critically examines the linear understanding of rural-to-urban migration in urban studies. Based on an eight-month-long qualitative empirical study in Dhaka, Bangladesh, this paper reports how migrants from different rural parts of the country, with their complex experiences around migrations, enter various spatial systems in urban Dhakaranging from shared living to institutional involvements to temporal displacements due to external factors(such as pandemic). This paper also documents how their nonlinear migratory journeys contribute to building a sense of urban resilience toward the uncertainties that various spatial systems offer to them. Drawing from a rich body of literature on urbanization, rural-urban migration, and actor-based resilience, we explain how alternative narratives of non-linear migration studies from our fieldwork can redefine urban resilience from a migrant’s perspective.

Authors: Rostami Soodabeh , Sindarreh Setayesh , Sigari Amirhossein Akhavan , Bani Marzieh Salimi , Taheri Behjat , Abbasi Saeed
Published: August 2023

Background:

Data gathering and bioinformatics play a significant role in the management and treatment of patients, especially of critically ill patients. This study assesses the feasibility and design of a registration system for nosocomial infections and sepsis in the intensive care unit of Alzahra university hospital in Isfahan.

Methods:

The members of the registration system consisting of physicians and nurses of the ICU, infectious disease and pulmonary specialists, microbiologists, infection control supervisors, and librarians. The data collection tool was a researcher-made checklist. To design the framework of the tool, researchers investigated various tools and indices in references and databases such as PubMed, Scopus, Web of Science, and national databases regarding ICU infection and disease registration systems. Essential items in this field were selected and a preliminary draft was prepared to record the data of patients with ICU-related infections. After applying experts' opinions, the checklist was reviewed, and the final approval of the checklist was obtained.

Results:

The final version of the checklist is prepared in three parts consisting of demographic data, principle variables (data required for registration of a patient), and the extended variables including details of the principle variables, and the data used to diagnose and treat.

Conclusion:

The ICU infection registration system can predict the prevalence of infection, monitor services and treatment of patients, analyze survival, assess clinical care outcomes, and investigate drug-related interventions. Reducing hospitalization costs by stratifying patients, providing a database for research studies, assessing the cost-effectiveness of interventions, are other advantages that resulted from the design of this system.
Efficacy of Balloon Angioplasty in Patients with Central Venous Stenosis or Obstruction Resulting from Central Vein Catheter Placement
Authors: Saroukhani Abbas , Sedighi Akbar
Published: August 2023

Background:

Prolonged catheter insertion in central veins of hemodialysis patients usually causes central venous stenosis (CVS). These patients present with upper limbs, head and neck, and chest edema or hemodialysis problems. This study was done to determine the clinical success of balloon angioplasty for the treatment of symptomatic CVS/obstruction.

Materials and Methods:

Sixty-one hemodialysis patients who underwent endovascular treatment for CVS enrolled in this cross-sectional study between January 2017 and July 2018 at our institute. Enrollment included 29 female and 32 male subjects with a mean age of 58.9 ± 9.9 (range: 33–78) years.

Results:

A total of 61 patients underwent interventions for endovascular treatment of central venous disease. 38 out of 61 patients completed all three phases of the study (the beginning, after 3 and 6 months). The average diameter of central vein in venography at the beginning of the study, 3 and 6 months later were 8.66 mm, 8.03 mm, and 7.66 mm, respectively. The average patency was 45%, and 54% and 51% at the beginning of the study, 3 and 6 months after the treatment, respectively. There was an increase in central vein patency after 3 months of treatment, with significant difference among 3 phases (P < 0.000).

Conclusion:

Endovascular treatment is effective and safe for patients with central vascular stenosis with less complication rate compared to open surgical treatments, and the rate of venous patency in the treated veins with balloon angioplasty after 3 months is excellent, but this rate after 6 months is significantly reduced.

Authors: Moradi Leila , Ahmadi Maryam Amir , Moaatamedfar Azim , Rashidi Homeira , Zaman Ferdos , Taheri Hamed
Published: August 2023

Background:

The aim of this study was to assess the prevalence of insulin resistance (HOMA-IR) between patients with and without thyroid nodules.

Materials and Methods:

This case–control study was performed on 86 patients with normal Thyroid-stimulating hormone (TSH) level (0.5–4.5 mIU/L) with thyroid nodules, who referred to Imam Khomeini and Golestan Hospitals (Ahvaz, Iran). Furthermore, 43 nonnodule patients with normal TSH level and normal thyroid ultrasonography were recruited from the general population as control group. The insulin resistance was evaluated for them made and the HOMA-IR ≥2.5 was defined as insulin resistance.

Results:

The mean of HOMA-IR value was significantly higher in thyroid nodule patients compared to controls (3.02 ± 1.92 vs. 1.10 ± 1.55; P < 0.001). Insulin resistance was seen in 49 thyroid nodule patients (57.0%), and 4 patients (9.3%) in the control group (P < 0.0001). Waist circumference, body mass index, fasting blood sugar, triglyceride, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and insulin levels were significantly higher in the thyroid nodule group.

Conclusions:

Our study shows there is an association between insulin resistance and thyroid nodules. The patients with thyroid nodules have higher HOMA-IR value.
Bloodless Management of Ankyloglossia
Authors: Aamir Mohammad , Shah Anshdha , Ambreen Zeba
Published: August 2023

ABSTRACT

Ankyloglossia is a congenital anomaly that occurs due to the presence of a short, thick lingual frenum that limits the tongue movement causing difficulty in speech and may pose a problem in maintenance of the periodontal health in the mandibular anterior region on the lingual aspect, thus affecting the health of the periodontium. The present case report described the case of an 18-year-old female who faced difficulty in pronouncing certain letters and presented with a diastema between the mandibular central incisors. She was diagnosed with Kotlow’s Class II ankyloglossia, and frenectomy of the lingual frenum was advised. The choice of method for the frenectomy was laser, so that only minimal bleeding occurred in an area that otherwise presents with profuse bleeding and reduces the patient morbidity. Posttreatment, good healing was seen, and the desired movement of the tongue was achieved.

CLINICAL RELEVANCE TO INTERDISCIPLINARY DENTISTRY

• Early diagnosis of ankyloglossia can help the pediatric dentist provide treatment accordingly to the child

• Correction of aberrant frenal attachment allows the periodontist to maintain a good periodontal health

• Relevant to the dental practitioner as the use of laser is advantageous in lingual frenectomy.
Diagnosis and Management of Peripheral Ossifying Fibroma

ABSTRACT

Localized gingival overgrowth occurs as a result of local irritation or as a response to an underlying systemic condition. When present, it results in a diagnostic dilemma – it could be due to pyogenic granuloma, peripheral ossifying fibroma (POF), peripheral giant cell fibroma, or peripheral odontogenic fibroma. Proper history and clinical and histopathological examination aid in diagnosis and treatment. POF is a focal, slow-growing, reactive lesion that is often present as a painless mass in the gingiva. POF can be sessile or pedunculated and predominately seen in the second decade of life with a female predilection. This article presents the diagnosis and management of POF in the maxillary premolar region of a 28-year-old female patient.

CLINICAL RELEVANCE TO INTERDISCIPLINARY DENTISTRY

• Peripheral ossifying fibroma is a soft tissue overgrowth that is clinically indistinguishable from many reactive soft tissue lesions and can only be diagnosed by histopathological evaluation

• In this case, the periodontist performed the surgical excision of the soft tissue lesion, and the oral Pathologist examined the lesion histologically and provided the final diagnosis.
Knowledge, Awareness, and Attitude Regarding Teledentistry among Undergraduate Dental Students: A Descriptive Study
Authors: Madhavan Karthik , Ganesh R. , Jeyamarthan S , Selvamani B
Published: August 2023

ABSTRACT

Aim:

The aim of this study was to determine the knowledge, awareness, and attitude regarding teledentistry among dental undergraduate students.

Background:

Teledentistry is a quickly forming subset of dentistry that is being used extensively in urban and rural areas addressing problems related to cost factors, effectiveness, efficiency, and quality in delivering high-quality oral health-care services.

Materials and Methods:

The current study is a descriptive cross-sectional survey of 203 undergraduate students, including students from 3rd year, 4th year, and interns. A pretested, self-structured, and closed-ended questionnaire was administered that consisted of 22 questions was included. The data are collected systematically and analyzed in frequency (yes/no).

Results:

From 209 undergraduate students, 203 participants responded, and it was observed that 71.3% of students knew teledentistry. Overall, it was found that compared to other years of undergraduate students, interns have a vague knowledge of teledentistry. The overall percentage for knowledge, awareness, and attitudes regarding teledentistry was 68.9%.

Conclusion:

The knowledge, awareness, and attitude were satisfactory among undergraduate dental students. However, there is a need to improve the knowledge and its usage to promote teledentistry.

CLINICAL RELEVANCE TO INTERDISCIPLINARY DENTISTRY

Teledentistry improves interdisciplinary dentistry by enabling distant consultations, teamwork, and coordination amongst dental professionals. It enhances patient monitoring and follow-up, facilitates effective case management and treatment sequencing, facilitates multidisciplinary training and education, and encourages interdisciplinary research and data exchange. It also increases access to specialised care. By extending the availability of comprehensive dental treatments across multiple specialties, teledentistry improves patient-centred care, convenience, and satisfaction.
Esthetic effects and color stability of resin infiltration on demineralized enamel lesions: A systematic review
Authors: Abang Ibrahim Dayang Fadzlina , Venkiteswaran Annapurny , Hasmun Noren Nor
Published: August 2023

Abstract

Aims and Objectives:

The aim of this study was to systematically review the ability of resin infiltration to conceal demineralized enamel lesions to normal enamel translucency and to maintain color stability.

Materials and Methods:

A literature search of PubMed, MEDLINE, Web of Science, and Scopus databases and a manual search of articles from 2009 to 2021 for randomized controlled trials (RCTs) and clinical efficacy trials (nonrandomized) were performed. Methodological quality and risk of bias (RoB) of included papers was assessed using Cochrane Collaboration Risk of Bias Tool 2.0 for RCTs and ROBINS-I (Risk Of Bias In Non-randomized Studies of Interventions) tool for nonrandomized studies.

Results:

A total of 352 titles and abstracts were reviewed. Eight RCTs and three clinical efficiency studies were included in this review. The masking effects of the demineralized enamel lesion were reported immediately after resin infiltration, and the color stability of this material was up to 24 months, with no adverse effects noted. For RCTs, four studies were classified as “some concerns” and four were as “low RoB.” For nonrandomized studies, all of the studies presented an overall moderate RoB.

Conclusion:

Resin infiltration achieves the best esthetic outcomes compared with microabrasion and remineralization therapy. Color stability was achieved with this material for up to 24 months and no adverse effects were noted. Factors contributing to the esthetic outcomes of the resin include the elimination of the hypermineralized surface layer, the homogeneity of the resin itself, and polishing after resin infiltration. Longitudinal follow-up and improved control of confounding variables should characterize future high-quality systematic reviews.
Are adults over 18 years of age with anaemia more likely to develop chronic periodontitis than adults without anaemia? - A systematic review and meta-analysis
Authors: Roberts Madison , Jimson Sudha , Srinivasan Mythily
Published: August 2023

Abstract

Aims and Objectives:

Periodontitis is a chronic disease affecting the supporting tissues of the teeth and exhibits bidirectional relation with systemic diseases. This study aims to determine the association between chronic periodontitis and erythrocyte functional measures: total red blood cells (RBCs), hemoglobin (Hb) concentration, mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration (MCHC) by systematic review and meta-analysis.

Materials and Methods:

A systematic search of the electronic databases PUBMED, OVID, Embase, Web on Science, and Google Scholar was undertaken from inception to July 2022. English language studies that evaluated the erythrocyte functional measures in periodontitis and health were selected. Other review reports, letters/opinion articles, studies without a definition of periodontitis, and the concomitant presence of systemic conditions (diabetes, kidney disease, cancer) were excluded. Two reviewers determined full-text eligibility in a blinded process. Meta-Essentials software was used to generate forest plots and to determine heterogeneity and publication bias.

Results:

Twenty-six studies involving 1082 patients with chronic periodontitis and 980 healthy controls were analyzed. Pooled results showed lower Hb concentration (Hedges’ g = −1.16; 95% confidence intervals [CI], −1.7 to −0.62), RBC counts (Hedges’ g = −0.85; 95% CI, −1.31 to −0.38) and packed cell volume (−0.56; 95% CI, −1.02 to −0.11) in patients with chronic periodontitis.

Conclusion:

This meta-analysis showed a decreasing trend in the hematological parameters, including hemoglobin concentration, number of erythrocytes, and hematocrit in patients with chronic periodontitis compared to healthy controls.
