In recent studies, the tumourigenesis and development of endometrial carcinoma (EC) have been correlated significantly with redox. We aimed to develop and validate a redox-related prognostic model of patients with EC to predict the prognosis and the efficacy of immunotherapy. We downloaded gene expression profiles and clinical information of patients with EC from the Cancer Genome Atlas (TCGA) and the Gene Ontology (GO) dataset. We identified two key differentially expressed redox genes (CYBA and SMPD3) by univariate Cox regression and utilised them to calculate the risk score of all samples. Based on the median of risk scores, we composed low-and high-risk groups and performed correlation analysis with immune cell infiltration and immune checkpoints. Finally, we constructed a nomogram of the prognostic model based on clinical factors and the risk score. We verified the predictive performance using receiver operating characteristic (ROC) and calibration curves. CYBA and SMPD3 were significantly related to the prognosis of patients with EC and used to construct a risk model. There were significant differences in survival, immune cell infiltration and immune checkpoints between the low-and high-risk groups. The nomogram developed with clinical indicators and the risk scores was effective in predicting the prognosis of patients with EC. In this study, a prognostic model constructed based on two redox-related genes (CYBA and SMPD3) were proved to be independent prognostic factors of EC and associated with tumour immune microenvironment. The redox signature genes have the potential to predict the prognosis and the immunotherapy efficacy of patients with EC.
La relation éducative : limites et « bonne distance » pour un bien-être partagé dans la classe
Authors: Frigout Stéphanie
Published: April 2023

Depuis la Loi pour la refondation de l’école de la République en 2013, l’usage du terme bienveillance n’a cessé de croître dans les textes et discours institutionnels sans pour autant permettre aux acteurs de se l’approprier subjectivement. L’analyse d’entretiens cliniques de recherche menés auprès d’enseignants à partir de ce terme montre que la question des limites, réelles, symboliques mais aussi psychiques, dans la relation à l’élève et aux parents d’élèves revient de manière récurrente. À partir d’éléments extraits de ces entretiens, cet article, inscrit dans l’approche clinique d’orientation psychanalytique en sciences de l’éducation, vise à montrer l’intérêt d’interroger les enjeux des limites pour penser la relation éducative avant de proposer des dispositifs groupaux susceptibles de favoriser une relation apaisée et bénéfique avec les élèves dans le respect de « la bonne distance ».
La relation éducative dans la pédagogie Montessori : réflexion sur des invariants pouvant contribuer au bien-être de l’élève.
Authors: Dubois Émilie
Published: April 2023

La pédagogie Montessori semble aujourd’hui bien installée dans le paysage des pédagogies alternatives. Ses particularités : un héritage de l’Éducation nouvelle, une rupture avec la forme scolaire, mais aussi, par l’intermédiaire d’un matériel médiateur, un changement dans relation éducative adultes / enfants. Comment la qualifier ? Quels sont ses spécificités, ses invariants ? Parce qu’elle repose sur des valeurs comme l’épanouissement de l’élève, le développement de ses capacités, de ses réussites ; mais aussi sur une posture de l’adulte-éducateur particulière, suffisamment en retrait pour ne pas gêner l’élève, tout en étant une ressource, une béquille, une source de motivation pour se mettre au travail, cette pédagogie pourrait, pour ces raisons, contribuer au bien-être de l’élève à l’école. Et s’il s’agissait d’une éthique éducative basée sur l’empathie ? C’est en mettant en perspective certains écrits de la pédagogue avec des exemples de situations de classe que nous proposons de réfléchir à cette question, en adoptant une posture de recherche qui mêle l’herméneutique textuelle et l’observation ethnographique.

Published: April 2023

Електричні апарати електромеханічного типу мають широке застосування у будь-якій галузі виробництва. Надійність їх роботи залежить від контактної системи. Такі вимикачі виконують функції розподілу електричної енергії в енергетичній системі та захисту під час виникнення аварійної ситуації. Тому вони є важливими елементами в системі електропостачання. Особливістю конструкцій багатоамперних автоматичних вимикачів є поділ контактів на головні та дугогасні. Головні контакти забезпечують пропускання номінального струму, а також струмів короткого замикання в зоні селективної роботи вимикача та відключення надструмів. Таким чином забезпечується процес бездугової комутації струмів головними контактами. Дугогасні контакти приймають все силове навантаження електричного ланцюга вимикача під час розходження контактів. Не виконання таких умов призводить до несвоєчасного розходження контактів і створення аварійної ситуації. Для підвищення працездатності контактів і вимикача в цілому, необхідно прагнути до зменшення їх перехідного опору в зоні контактування і підвищенню електродинамічної стійкості. У роботі проводиться аналіз можливості використання псевдорідиннометалевих контактів (ПРМК) у головних ланцюгах полюсів багатоамперних автоматичних вимикачів. Завдяки попередньому дослідженню матеріалу контактів визначена їх особливість роботи під час експлуатації. Реальною перспективою використання псевдорідиннометалевих контактів є нетрадиційні підходи, що забезпечують створення та застосування безсрібних контактів. Фізичні процеси, що виникають на робочій поверхні контактів ПРМК та їх розвиток залежить від розподілу теплового й електричного поля у динамічному режимі. Особливість матеріалу контактної композиції та технології їх виготовлення сприяють використанню різних методів та принципів приведення в контакт рідкої та твердої фази. У сукупності контактні композиції працюють внаслідок впливу електромагнітного поля на феромагнітний плунжер завдяки дії капілярних сил.

The mechanical alloy Mg + 10 wt.% Ti and two mechanical alloys MgH2 + 10 wt.% Ti were synthesized by a reactive mechanical alloying (RMA) method, but in different ways. The influence of doping and the preparation procedure of mechanical alloys (MAs) on thehydrogen sorption properties, temperature and decomposition kinetics of their MgH2 phase was investigated by isobaric thermodesorption spectroscopy at a constant hydrogen pressure of 0.1 MPa. The desorption kinetics of the milled MgH2 + 10 wt.% Ti are faster than in the case of the ball milled Mg + 10 wt.% Ti. It was found that the manner of obtaining a mechanical alloys by reactive milling of MgH2 +10 wt. % Ti powder mixture rather than Mg +10 wt. % Ti powder mixture  to improve the kinetic characteristics. The role of Ti as an alloying element in improving the hydrogen desorption kinetics of МAs obtained by various preparation procedures was studied. The stabilizing effect of Ti on the nanocrystalline structure and growth of the crystallites (grains) of the MgH2 phase during the cycling was also evaluated. It has been established the practical absence of the influence of Ti additive and the manner of obtaining MAs on the its thermodynamic stability.
Дослідження диференційної міграції мангану у сільськогосподарських землях шляхом комплексування методів

Екологічні дослідження урбанізованих територій та оцінка стану навколишнього середовища є пріоритетними напрямками науки сьогодення. Їх актуальність обумовлена необхідністю виявлення факторів і причин формування екологічної ситуації в екосистемах, виділення пріоритетних проблем і вивчення просторової диференціації урбанізованих територій з метою створення безпечного та комфортного середовища проживання населення. У більшості випадків сучасна оцінка якості навколишнього середовища базується лише на статистичних даних (рівень викидів, концентрація мікроелементів в ґрунті та ін.), які є доступними достатньо широкому колу суспільства, але не можуть повністю представити реальну екологічну ситуацію та надати уявлення про особливості просторової структури забруднення території. Манган розповсюджений в ґрунтах у вигляді оксидів і гідрооксидів, що осіли як на ґрунтових частках, так і у вигляді конкрецій різного діаметра. В процесі вивітрювання двовалентний марганець  переходить в карбонат або в бікарбонат. Манган накопичується у верхньому горизонті більшості ґрунтів; це накопичення особливо чітке в ґрунтах лісової зони. Проведеними дослідженнями підтверджено, допоки важкі метали тісно пов’язані зі складовими частинами ґрунту і важкодоступні, їх негативний вплив на ґрунти і навколишнє середовище буде незначним. Однак, якщо ґрунтові умови дозволяють перейти важким металам в ґрунтовий розчин, з’являється пряма загроза забрудненню ґрунтів, виникає можливість проникнення їх в рослини. Проведені дослідження сільськогосподарських земель, що знаходяться навколо регулюючих басейнів геофізичним методом природного імпульсного електромагнітного поля Землі, дозволили встановити положення зон фільтрації води у прилеглих до басейну ґрунтах та напрямок міграції вод, що містять розчинену форму мангану, проаналізовано характер протікання цих процесів та можливі наслідки.

Digital technology in a crisis: Role of digital and cloud maturity in organisations surviving and thriving through pandemic crisis
Authors: KANG Khoon Seang
Published: April 2023

The COVID-19 epidemic forced Singapore to implement a smart lockdown in April 2020. As a result, many businesses were forced to rapidly expedite their shift to digital technologies. Despite many businesses' valiant efforts and great accomplishments, the epidemic has revealed the various ways in which these businesses are susceptible to a crisis. Digital technology has proven to be one of the most essential options for many businesses seeking to grow. This entails making the transition from active experimenting to active scaling up. Regardless of the immense obstacles that many businesses are facing today, they have now recognized that this is the moment to focus and act on new principles and strategies in order to adapt to the changing situation.

This manuscript is summary of the results from the qualitative content analysis conducted during the dissertation, to study in what ways are these financial services institutes  created or adjusted strategies based on digital technology to become more robust in contexts marked by high uncertainty levels and disruptions. Workplace innovation can be described as the extent to which businesses seek out new ideas in order to improve the engagement of their employees by improving their working conditions, fostering a culture of competent environmental change response, and increasing productivity. On the other hand, digital technology can be defined as all devices, systems, electronic tools, and other resources that, process, generate, and store data
Co-creating New Dancefloors Through a Parallel Organisation
Authors: Lebesby Kristin , Finnestrand Hanne , Vie Ola Edvin
Published: April 2023

Across industries, union density is under great pressure from different forms of organisations and, in many ways, a more individualised working life. Employee relations within the public sector have undergone a transition due to privatisation, decentralisation, and the adoption of quality management approaches. Employee relations in Nordic countries are strongly embedded in national regulations and agreements. However, research on workplace development within the public sector rarely includes discussions of the union role. The Nordic model perspective acknowledges that the different social parties share interests and visions, and it promotes a collective effort when workplace development is sought. This paper poses the question of how public organisations can change the “boxing and dancing” behaviour in union–management relationships through the establishment of a parallel organisation (PO). The PO serves as a different organisational mode when the operating organisation is unable to successfully deal with certain prevailing issues, where knowledge rather than authority should determine decisions. The findings show that the PO creates a “dancefloor”, less confined by bureaucratic barriers, where unions and managers co-create new relations. In addition, participants experience more enhancement of their roles, and their focus towards developing their workplace collectively is more prominent. Our findings contribute to the industrial relations literature by proposing POs as a tool for building relations between unions and managers in a public organisation. Our paper also contributes to the PO literature by proposing that the inclusion of unions in a PO can be crucial when attempting to transfer outcomes into the operating organisation.

Introduction: The purpose of Occupational Safety and Health (OSH) is to protect and prevent workers from being exposed to risks and hazards that are detrimental to their health and safety. For the past two years, the coronavirus disease 2019 (COVID-19) is one of the most significant occupational health outcomes to physical therapists (PTs) due to the nature of their work. However, minimal studies have been conducted about the experiences and OSH practices of PTs during the pandemic. This study aims to understand the experiences of clinical PTs in Metro Manila, Philippines during the pandemic. The study also seeks to explore the OSH practices and responses of PTs to presenting occupational risks and hazards through a qualitative descriptive study design.

Methods: In this qualitative descriptive study, a maximum variation purposeful sampling method will be used in recruiting an estimated total of twelve (12) participants. A preliminary questionnaire would be disseminated via Google Forms to determine the eligibility of potential participants. Data will be gathered through a one-to-one semi-structured online interview, which will be transcribed verbatim and recorded with audio and video. Both manual coding and software-aided coding (NVivo) will be utilized in the data analysis. Emerging themes will be identified using thematic inductive analysis.

Discussion: The results of the study may contribute to the formulation of better guidelines in handling infectious diseases even after quarantine restrictions are lifted. Furthermore, the findings will also provide the groundwork for the local body of knowledge in the Philippines and may serve as a future reference for research concerning OSH practices in physical therapy locally.

Introduction: Stroke is the third leading cause of death in the Philippines, so these patients must continuously undergo rehabilitation for faster recovery.
With the rise of COVID-19, physical therapy (PT) telerehabilitation (TR) has emerged, where services are provided outside the usual rehabilitation setting for patients with stroke to continue their treatment while reducing the risk of acquiring COVID-19. However, it is a relatively new service in the country; hence, further research is needed to identify the factors and needs of these patients during TR, which may help improve PT TR services.
Objective: This study aims to explore the experiences and perspectives of Filipino patients with stroke who have undergone PT TR in the Philippines since March 2020. Administrators of healthcare facilities, policy-makers, and other decision-makers involved in evaluating, implementing, and developing PT TR may benefit patients with stroke. This can expand the scope of rehabilitation to patients with stroke who have no access to face-toface rehabilitation or improve the training or education of Physical Therapists who are providing TR to stroke patients.
Methods: This will be a qualitative phenomenological study design that will use purposive sampling to recruit participants. Semi-structured interviews (SSI) will be conducted online using Google Meetings®, Zoom®, or Facebook Messenger® to record their experiences and perspectives. The NVivo data analysis software will be used to create codes and identify themes from the data gathered. The data that will be obtained is about the experiences and perspectives of Filipino patients with stroke regarding PT TR. The insights of the participants will undergo Thematic Analysis until no new information will be discovered from the analyzed data.
Ser paciente como categoría límite de la galenidad: un análisis relacional a la deshumanización de la medicina
Authors: Villanueva Marcia
Published: April 2023

En este artículo presento un análisis de la identidad de médicos y pacientes con base en la teoría sobre la construcción socionarrativa de las identidades propuesta por Lindemann. La tesis principal es que la identidad de los pacientes se construye como contraparte de la galenidad. Ésta se refiere a la identidad profesional de los médicos, constituida por narrativas socialmente compartidas que representan a estos profesionistas como individuos sobresalientes y capaces de realizar acciones heroicas o incluso sobrenaturales, llegando a veces a compararlos con dioses y superhéroes, lo que en última instancia los deshumaniza. Utilizo la noción de pareja simbólica que Serret ha propuesto para caracterizar las identidades de género con el fin de argumentar que, en el binomio médico-paciente, la identidad del primero es la categoría central masculinizada y la del segundo es la categoría límite feminizada, que se define como la negación de la anterior. El argumento está ilustrado con hallazgos recabados mediante técnicas de investigación etnográficas (26 entrevistas semiestructuradas a estudiantes de medicina y médicos profesionistas mexicanos, así como material recabado mediante una etnografía virtual en grupos de médicos mexicanos y perfiles afines en Facebook entre 2014 y 2018). El artículo concluye que la deshumanización de la medicina no sólo es resultado de las caracterizaciones subhumanas que los médicos hacen de los pacientes, sino que se refiere sobre todo a un fenómeno relacional que opera bajo una lógica patriarcal en el cual la deshumanización de los pacientes aparece como contraparte de la dehumanziación de los médicos.
Subsurface Structural Image of Galabat Field, North East of Iraq Using 2D Seismic Data

Published: April 2023

This research had been achieved to identify the image of the subsurface structure representing the Tertiary period in the Galabat Field northeast of Iraq using 2D seismic survey measurements. Synthetic seismograms of the Galabat-3 well were generated in order to identify and pick the reflectors in seismic sections. Structural Images were drawn in the time domain and then converted to the depth domain by using average velocities. Structurally, seismic sections illustrate these reflectors are affected by two reverse faults affected on the Jeribe Formation and the layers below with the increase in the density of the reverse faults in the northern division. The structural maps show Galabat field, which consists of longitudinal Asymmetrical narrow anticline of Fatha and Jeribe formations, where the Southeastern limb is steeper than the Northeastern limb. The seismic interpretation shows that Galabat Field has a positive inverted structure, it is an anticline at the level of the Tertiary Period. The direction of the anticline axis and the major reverses faults are Northwest -Southeast. It is concluded from the study that reverse faults originated due to Zagros tectonism which is widespread in the area are a major conduit that channeled petroleum flow from source to Miocene traps. In addition, these faults were caused by the presence of salt accumulation within the Fatha Formation and led to high variation in the thickness in the crest and limbs of the Galabat structure.

Published: April 2023

The Allochthonous Visean limestones of the Eastern part of the Moroccan central massif, occurring along the front of the Jebel Bou Khmis thrust fault, between Mrirt and Amghass, have undergone a structural and microtectonic study, aiming to study fracturing and its relationship between folding. The microtectonic studied sites were selected in different folds and in different parts of the same fold (long and short limbs and in the hinge) in order to study the relationship with fold geometry and fracturing, and to show the control of the facies and its importance in the genesis of fracture networks. The sub-vertical fractures family appear to be anterior to sub-horizontal once. They correspond to the first deformation accompanying the first shortening phases during the layer parallel shortening (LPS). The horizontal fractures were developed by accommodating of the fold when extending vertically during the amplification of the hinge. These three fracture families are syn- to post major folding phase that generated penetrative NE-SW oriented cleavage. The same results were obtained from microscopic study of thin sections, selected among oriented limestone samples, within oolites, calcite crystals and fluid inclusions.
COMPARISON OF TWO DIFFERENT WAFER BAKING PLATE LOCKING MECHANISMS IN WAFER FURNACES IN TERMS OF STRESSES

A wafer baking plate is set in wafer ovens, and wafer dough is baked to produce wafer sheets. Since wafer dough contains more than 50% water and is baked in a closed environment, it creates high pressure over time. This pressure puts considerable strain on the wafer baking plate and locking mechanisms and adversely affects the locking mechanism. In this case, it is necessary to calculate the stresses and displacements on the parts by modelling the loads and the boundary conditions specific to the problem for various plate locking mechanisms. This study used the finite element method to calculate and compare the stress and displacement values on two different locking mechanisms of a wafer baking plate. As a result of the analysis, the Von Mises stress value of the butterfly lock mechanism was 34.5% higher than the hook lock mechanism. The displacement value of the hook lock mechanism is 9.5% lower than the butterfly lock mechanism. Since the total contact area of the butterfly lock mechanism is shallow and the Von Mises stress value is higher than the other mechanism, it is predicted that the wear will be higher in continuous operation.

This article presents an introduction to green tribology, a new direction in the field's evolution, an exciting new topic for scientific study, and a novel approach to making tribology a friend to the environment and a proponent of energy conservation. Green engineering and green chemistry are two more "green" fields that are thought to be closely related to green tribology. The article has discussions on a variety of green tribology topics, including the concept, views, role and goal, major principles, key areas, challenges, and future development directions. As an interdisciplinary topic combining energy, materials science, green lubrication, and environmental science, green tribology also attracted human interest due to its biomimetic approach. Hence, the use of biomimicry in environmental design is also discussed in this article.

Non-movable threaded joints (bolted connections) and movable threaded joints (power screws) are subassemblies that have a large field of application in the mechanical industry. With these subassemblies, a part of the input energy in the form of torque is spent on overcoming friction on the contact sliding surfaces. These energy losses mostly depend on the geometric and tribological characteristics of the threaded joint. Compared to bolted joints, power screws consume significantly more energy to perform their elementary function. Bolted joints have a much larger field of application in the mechanical industry. In the case of bolted joints metric thread is the most common, and in power screws, threaded joints with a trapezoidal thread. Accordingly, this paper analyses the effects of the coefficient of friction and geometric and kinematic parameters on the energy efficiency of trapezoidal and metric threaded joints. The performed analysis can be used to select the optimal parameters of the threaded joints from the aspect of energy efficiency during the design of new or reconstruction of existing machine structures.

With the development of contemporary drive systems that have a lower or zero emission of exhaust products, a significant reduction in the harmful influence of traffic on the environment has been achieved, but today new pollutants have been identified on the vehicle. One of such non-exhaust pollutant are brakes whose wear can be a significant particulate matter (PM) contributor. Examining the mechanisms of the formation of particles during braking, and therefore, brake wear is becoming one of the important areas of research today. There are several tests and driving cycles that are applied during the research of the brakes, but they are not primarily defined for testing particle emissions during braking. UNECE (United Nations Economic Commission for Europe) has included in its plan the introduction of standardised cycles that will prescribe a brake cycle whose purpose will be to examine the formation of particles. The brake pads are made of a mixture of different materials that ensure the longevity and efficiency of the brake system and the applied materials have different wear intensities in certain operating conditions. The most common laboratory tests in this area are performed using inertial brake dynamometers. This paper presents an experimental planning method of quantifying the influence of some of the operating parameters (initial speed of the vehicle, braking pressure and vehicle’s load per one brake disc-pads friction pair) on the airborne particulate matter for four different brake pads materials during testing on an inertial brake dynamometer.

Published: April 2023

Introduction: Oral cancer is the sixth most common malignancy worldwide and accounts for 30% of all cancers in India, with 5-year survival rate, except when diagnosed in the early stages. Hence, early diagnosis of oral cancer is very much essential for the sake of the patient. However its burden on the economy for providinghealthcare is substantial and with the increasing incidence of oral cancer in developing countries like India and the other South-East-Asian countries, the role of screening methodologies for early detection of pre – cancerous and cancerous lesions of oral cavity are becoming more vital

Methodology: An observational cross-sectional study conducted in the departments of Otolaryngology & head neck surgery in close association with department of Pathology in a tertiary based teaching institute in North Bengal, India, during April 2021 to March 2022. All the patients aged above 18 years, who visited the outpatient department of Otolaryngology & Head Neck Surgery, and admitted in the ward of the same, having oral lesions which are clinically suspected as pre- malignant and malignant lesions were included in this study.

Results: The study population comprised of total 69 cases. Among them 47 cases (~68%) were malignantlesions, 13 (~19%) cases were pre-malignant and 9 (~13%) cases were diagnosed as benign lesions consideringHistopathology result. 30 (63.8%) out of 47 malignant cases show class-5 cytological grading in brush cytology smear, stained with Pap stain. 25.5% of the malignant cases were in class-4 and 10.6% cases were in class-3 whereas, in premalignant cases (n=13), 3 cases were in class-2 and 7 cases were in class-3 and 3 were in class-1. Maximum value of AgNOR counts for benign, pre malignant and malignant lesions were 3.54, 4.16, 7.28 respectively.

Conclusion: The brush cytology with PAP grading and AgNOR analysis in clinically suspected    oral lesionscan be used as an early diagnostic tool for diagnosing oral squamous cell carcinoma especially for lower socio-economic status people who present with late stages.

Pathological processes associated with ageing increase the risk of cognitive deficits and dementia. Frailty syndrome, also known as weakness or reserve depletion syndrome, may significantly accelerate these pathological processes in the elderly population. Frailty syndrome is characterized by decreased physiological function and neuropsychiatric symptoms, including cognitive decline and depressive states. In people with cardiovascular disease, the risk of frailty is three times higher. Frailty syndrome is particularly prevalent in severe heart failure, which increases the risk of mortality, increases hospital readmission, and reduces patients' quality of life. In addition, co-occurrence of cognitive impairment and frailty syndrome significantly increases the risk of dementia and other adverse outcomes, including mortality, in the heart failure population.

Water is essential for living beings. It is also one of the main means of transporting contaminants such as pathogenic bacteria. Therefore, water quality must meet basic requirements so that it can be consumed by the population and for use in industries. The objective of this work was to carry out a comparison of two analysis methods (Petrifilm® and Chromogenic Substrate) of water in the beverage industry, contributing to the validation study of the Petrifilm® method for analysis of process water for coliform microorganisms. Currently, only the Chromogenic Substrate method is validated by the Standard Methods for the Examination of Water and Wastewater. The study was carried out in a soda fountain in the city of Jundiaí-SP. Tests were performed over a period of 6 months, weekly (for process water) and monthly (for line swab). Specific points were chosen for sample collection according to the internal procedure. The obtained results demonstrated that the Petrifilm® method was not efficient to demonstrate the presence of coliforms and comparison with the chromogenic substrate.
