Progressed Learners’ Participation in Developing Curriculum Support Programmes: A Critical Pedagogy Approach
Authors: Mogale Makobo Lydia , Malatji Khashane Stephen
Published: October 2022

This empirical paper provides a critical analysis of progressed learners’ participation in the development of curriculum support programmes through Paulo Freire’s critical pedagogy. Progression policy was promulgated in the Further Education and Training Phase to ensure uniformity and consistency in the implementation of National Policy Pertaining to the Programme and Promotion Requirements (N4PR) to prohibit learners from spending more than four years in a phase. The policy stresses the development of intervention programmes for identified learners to bridge the content gap. However, literature based on progression policy focus on programmes that teachers develop and implement. The focus of this paper is on progressed learners’ contribution to curriculum support. Through Freire’s critical pedagogy, it critiques traditional teaching methods where the teacher is the knower who deposits knowledge to novice “progressed” learners. In an argument for a problem posing education, the study employs a qualitative research approach. Data was collected through document analysis and interviews with six teachers. Thematic analysis was used for data analysis. The findings of the study revealed a lack of evidence of progressed learner participation in the development of curriculum support programmes. In addition, progressed learners feature when they have to respond to developed programmes. This study concludes that teachers are fixated on traditional learning models. Based on the findings, the study recommends the need to shift to a “dialogue approach” where both the teacher and progressed learners design intervention strategies that communicate directly to the specific needs of such learners.

Imagens de gênero e raça na tecnologia da informação: invisibilidades negras, territórios brancos; mulheres ocultas, espaços masculinos
Authors: Pereira de Souza Tatiele , Dias Tosta Tania Ludmila
Published: October 2022

A tecnologia da informação (TI) apresenta-se como um campo significativo para a análise das assimetrias sociais nas relações de trabalho, não por envolver um alto índice de minorias seja no campo das relações raciais seja no campo das relações de gênero, mas exatamente pelo inverso, constituindo-se como uma arena marcada pela configuração de um perfil de profissional branco e masculino. Este é o quadro que estrutura os objetivos desse artigo: analisar as desigualdades de gênero e raciais na TI, por meio de uma triangulação de métodos quantitativos e qualitativos. Os resultados permitem identificar a constituição de um perfil de profissional que coaduna com os referenciais masculinos e brancos no campo, erigindo representações que podem interferir nas escolhas e trajetórias profissionais de homens e mulheres no mercado de trabalho.

Le regroupement des hôpitaux publics : l’action publique en régime d’apprentissage
Authors: Cazin Léo , Kletz Frédéric , Sardas Jean-Claude
Published: October 2022

Les GHT (Groupements Hospitaliers de Territoire), introduits avec la loi de modernisation de notre système de Santé (2016), s’inscrivent dans une histoire longue et complexe du déploiement par la puissance publique de réformes visant à réorganiser le paysage hospitalier, mais dont les effets ont été souvent modestes. Ce papier s’intéresse, sur la base de l’étude de cas de construction de GHT, aux formes que prennent les nouvelles coopérations nées sur le terrain et à leurs effets. Nous montrons que cette réforme dont les objectifs sont en apparence vagues peut marquer une rupture en visant cette fois à amorcer des dynamiques locales d’exploration de nouvelles modalités d’organisation territoriale de l’offre de soins. Ces évolutions sont rendues possibles par l’irruption d’un nouveau régime de gouvernementalité, qui offre aux acteurs des objets de gouvernement, tels le parcours des patients, capables d’enclencher de nouvelles dynamiques d’apprentissage, à travers la mise en place de partenariats d’exploration. Nous étudions ce nouveau régime et ses effets au sein des GHT, et dégageons les conditions à réunir pour mener à bien ces orientations.
Intérêt et limites de la modélisation en matière de gestion des épidémies
Authors: Temime Laura
Published: October 2022

Les modèles mathématiques sont très utiles pour bien comprendre et gérer le risque épidémique, comme l’a illustré leur usage lors de la pandémie de Covid-19. Utilisés depuis plus d’un siècle, ils permettent, en proposant une simplification de la réalité informée par des données, d’explorer une large gamme de scénarios hypothétiques. Cependant, leur bonne utilisation pour aider à la décision en santé publique suppose un travail en interaction avec les acteurs de terrain, la prise en compte des incertitudes et un effort de communication.
Covid-19 et nouveaux mécanismes de régulation économique
Authors: Chevalier Olivia
Published: October 2022

Nous aborderons dans cet article divers aspects de la crise sanitaire sous l’angle économique. D’abord, dans un contexte d’incertitude radicale non réductible à des risques probabilisables, cette crise spécifique a donné lieu à un fort investissement public dans tous les domaines, faisant apparaître une nouvelle fonction régalienne, selon les mots du prix Nobel d’économie Edmund Phelps, celle d’« assureur systémique ». Puisque la crise sanitaire a mobilisé les données de santé, nous nous concentrerons sur la numérisation du secteur de la santé français, dont les failles, pointées de longue date par les professionnels, syndicats et associations, ont été à nouveau mises en lumière par la pandémie (notamment, le retard relatif du secteur en matière d’intégration massive de l’IA). Il en résulte des difficultés relatives à ce qui est, de facto , une extension du pouvoir étatique dans le domaine économique, donc dans la société civile, et aux modes de financement de l’État-assureur, dont un des effets les plus patents et inquiétants est le piège inflationniste.

Dans cet article, nous discutons les éléments scientifiques, décisionnels, organisationnels et opérationnels qu’il convient de prendre en compte pour y faire face.
L’acceptabilité sociale des mesures sanitaires : retour sur l’impératif de la participation publique
Authors: Friser Alice , Arpin Marie-Luc , Gendron Corinne , Yates Stéphanie
Published: October 2022

Alors que le courant de l’acceptabilité sociale s’est construit en lien étroit avec les pratiques de participation publique, au point que plusieurs les estiment consubstantiels, force est de constater que l’acceptabilité sociale est souvent tacite ou passive. Ainsi, la légitimité de décisions prises unilatéralement est peu remise en question en contexte de crise, comme l’illustre la gestion de la pandémie de Covid-19. Pour autant, les mesures de confinement ont peu à peu suscité un malaise démocratique comme l’ont souligné plusieurs observateurs. Ce qui pose la question suivante : jusqu’à quel point l’urgence et le recours à l’expertise institutionnelle peuvent-ils se substituer à la participation publique pour légitimer les décisions publiques ? En revisitant la littérature sur l’acceptabilité sociale à l’aune de la crise sanitaire, nous avançons l’idée qu’en dépit des craintes de certaines administrations, il est avantageux d’ouvrir le débat à propos des mesures de gestion sanitaire plutôt que de confiner la décision à un cénacle de responsables politiques et d’experts institutionnels.
An alternating direction power-method for computing the largest singular value and singular vectors of a matrix
Authors: Duan Yonghong , Wen Ruiping
Published: October 2022

The singular value decomposition (SVD) is an important tool in matrix theory and numerical linear algebra. Research on the efficient numerical algorithms for computing the SVD of a matrix is extensive in the past decades. In this paper, we propose an alternating direction power-method for computing the largest singular value and singular vector of a matrix. The new method is similar to the well-known power method but needs fewer operations in the iterations. Convergence of the new method is proved under suitable conditions. Theoretical analysis and numerical experiments show both that the new method is feasible and is effective than the power method in some cases.

Alpine Clichés and Critiques: Developments and Tensions in German-Language Literature
Authors: Lughofer Johann Georg
Published: October 2022

This article argues that the role of the Alps in German-language literature is embedded both in a socio-historical context and in the topoi or commonplaces that emerged from that context. Using examples drawn primarily from two very different Austrian authors of the interwar period—namely, Joseph Roth (1894–1939) and Ödön von Horváth (1901–1938)—as well as from their German-speaking predecessors and successors, the aim is to show the literary approaches used to undermine traditional topoi. Today, the Alps are the quintessential defining landscape for the Republic of Austria as well as for Austrian literature, yet they were demystified already in the literature of the interwar period. The themes and literary strategies of these literary works anticipate post-1945 literature, while showing surprising breadth in their approach to the Alps. Much of what is commonly understood today as a reaction to the use of the Alpine and of alpinism for Nazi propaganda belongs in fact to older traditions.
“This Fabulous Rainbow of Sensations”: The Haptic Sublime in Modern Polish Mountaineering Literature
Authors: Kaliszuk Przemysław
Published: October 2022

This article looks at Polish mountaineering literature in the context of modernist aesthetics. Selected extracts from nineteenth-century travel writing are presented in which the essence of one’s experience of mountains is associated with the sublime. The article then explores the emergence of a new type of climbing sensibility and its literary representation on the basis of twentieth-century mountaineering texts that show the inefficiency of earlier forms of the sublime. Polish mountaineers gradually developed a new language that allowed them to specify the experience of vertical space. The aesthetics of the haptic sublime, which was born of the clash of the literary discourse with the concreteness of the climbing experience, resolved the problem of satisfactory expression and introduced new narrative patterns. It placed the climbing experience in a new conceptual framework, deriving its unique character from the contradictions of modern culture. It also showed the autotelic character of climbing and constituted mountaineering literature as a type of narrative that is autonomous with regard to other kinds of travel narratives.
Biopolitični prispevek francoskih pravljic poznega 17. stoletja k oblikovanju disciplinarne družbe
Authors: Tratnik Polona
Published: October 2022

V članku obravnavam oblikovanje disciplinarne družbe, kot se kaže v aristokratski kulturi francoskih pravljičarjev in pravljičark konec sedemnajstega stoletja. Pravljice tedaj igrajo pomembno vlogo v procesu, ki ga je Norbert Elias imenoval proces civiliziranja. V primeru pravljic je to pomenilo oblikovanje vljudne dvorske družbe in v veliki meri discipliniranje žensk. Raziščem biopolitične vidike pravljic v tistih okoliščinah, saj se ravno tedaj skozi pravljice kažejo družbeni premiki in konsolidacija določenih konceptov; zlasti se vzpostavljata določen koncept feminilnosti in družbena vloga ženske, ki ostajata v veliki meri nespremenjena tudi kasneje. Preučujem pravljico o Pepelki, kot sta jo zapisala Charles Perrault in Marie-Catherine d’Aulnoy. Na primerih obravnavam reprezentacijo spola, spolnih vlog in odnosov, kot tudi sporočilnost in moralni poduk. Sredi dvajsetega stoletja je Walt Disney priredil Perraultovo Pepelko, s čimer je ta inačica postala svetovno najbolj znana pravljica o Pepelki. Biopolitični pomen Perraultove Pepelke oziroma Disneyeve priredbe Pepelke kot verjetno najbolj globalizirane zgodbe nasploh je bil in je še vedno izjemen.
Poezija Williama Butlerja Yeatsa v prevodih Nade Grošelj in Vena Tauferja
Authors: Strle Urša
Published: October 2022

Članek obravnava pet pesmi W. B. Yeatsa v primerjavi s prevodi Vena Tauferja in Nade Grošelj. Namen članka je z analizo ritma, verzne oblike in različnih pesniških figur ugotoviti, kako in do kakšne mere so v slovenskih prevodih ohranjeni elementi izvirnika in kaj se je v njih izgubilo – ali dodalo. Ugotovitve potrjujejo dejstvo, da lahko težave pri prevajanju povzročajo odsotnost glagolskih in pridevniških končnic ter raba neosebnih oblik v angleščini; predvsem pa problem predstavljajo polnopomenske enozložnice, ki jih je v angleškem besedišču obilo, njihove slovenske ustreznice pa so pogosto precej daljše. Enoznačnega odgovora na vprašanje, ali naj prevajalec ohrani metrično shemo in okrni vsebino ali pa ohrani vsebinske enote in krši ritmično podobo pesmi, ni, na kar kažejo različni modeli prevajanja poezije. To pa potrjujejo tudi primeri prevodov Nade Grošelj in Vena Tauferja, ki se razhajajo v pristopu glede ritma in vsebine. Kljub razlikam pa oba karseda skrbno ohranjata zvočne značilnosti izvirnika, kar ponuja odgovor, da je zven vsaj v toliki meri zaslužen za končni učinek pesmi kot sama vsebina in ritem.
Flying Ad hoc Networks Routing Constraints and Challenge Perspectives
Authors: Perumal Sudarson Rama , V. Muthumanikandan , J. Sushmitha
Published: October 2022

In recent decades, the most rapid change in wireless technology has been that flying ad hoc networks (FANETs) played a vital role in telecommunications. FANETs are flexible, inexpensive, and faster to deploy, which has led to the pathway to apply them in various applications such as military and civilian. However, FANETs have high mobility, and frequently changing topology patterns and tri-dimensional space movement make routing a challenging task in FANETs. FANETs differ from vehicular ad hoc network (VANETs) and mobile ad hoc networks (MANETs) in terms of features and attributes. It is always a challenge to choose the optimal path in any network using routing protocol. Due to these challenges, the performance and efficiency of the routing protocol have become critical. As network performance metrics like throughput, quality of service, user experience, response time, and other key parameters depends on the efficiency of the algorithm running inside the routing protocol, this chapter presents a novel routing protocol for FANETs in terms of distributed network routing algorithms and data forwarding routing.
A Review of Various Modeling Software for VANETs
Authors: L. Divya , T. S. Pradeep Kumar
Published: October 2022

There is great demand for VANETs in recent times. VANETs enable vehicular communication with the advent of latest trends in communication like 5G technology, software-defined networks, and fog and edge computing. Novel applications are evolving in recent times on VANETs with the proliferation of internet of things. Real test bed implementation is not always feasible with various limitations like expenditure and manpower and requires more time to experiment with the new facets of VANETs. Hence, the researchers should be aware of the variety of simulation tools that are capable of running VANET simulations. Simulation is a powerful tool in developing any critical/complex system that constitutes minimum cost and effort. The simulation tools of VANETs should support multiple mobility models, real-world communication protocols, and traffic modeling scenarios. This chapter gives a clear view on available tools and their characteristics on VANETs for research purposes.

Authors: Veerasamy Vanitha , Natarajan Rajathi
Published: October 2022

Unmanned aerial vehicles (UAVs), typically known as drones, are aerial machines that can be programmed and controlled remotely using mobile devices and are connected via wireless communication technology. Because of their ease of deployment, dynamic configuration, low maintenance costs, high mobility, and faster reaction, they are becoming more widely used in a variety of applications. As a result, a new paradigm known as flying ad hoc networks (FANETs) has emerged, which is a subset of mobile ad hoc networks with special aviation-related properties. FANET ideas have been combined with the internet of things (IoT), resulting in the internet of flying things (IoFT), a paradigm that enables a significant new level of applications, solves existing challenges in UAVs and IoT, and broadens the spectrum of potential uses. This study focuses on various IoFT applications and challenges in IoFT implementation.

Published: October 2022

The modern smart cities completely rely on the technology where the smart and intelligent-based transportation management system is a primary requirement and that can only be achieved by the advancement in traditional vehicular ad-hoc network (VANET). The primary two techniques such as IoT and security mechanism are incorporated with the VANET system which helps to design the robust framework. Due to quick transformation in technological landscape, the threats and attacks also get advanced. The most prominent characteristics of the VANET is to provide the self-aware system which assists for the better management in the transportation system. As per the advancement in the attacks, the robust defense mechanism should also be increased. If not, there would be the huge loss in terms of the lives of living beings, societal, and economic. Therefore, this study is completely based on the analysis and recommendation for developing the robust IOV system, which ensures the secure infrastructure.

Resilience, Stress, and Mental Health
Authors: Malik Muniza
Published: October 2022

This chapter explains the role of resilience in dealing stress effectively and to ensure good mental health. In the phase of COVID-19, people passed through different types of stresses ranging from social to economic, which affected the mental health of individuals. Resilience is a skill, pretty much like an asset provided to all individuals by nature, but its effective usage tends to prevent stress, anxiety, and depression. Resilience is a dynamic system of interaction with varying events of life. Facing a severe trauma and rising up from the downfall with greater strength than earlier represents adaptation of the individual. It is important to understand that resilience develops from day-to-day events and it can be learned at any age. Understanding of resilience as a process is more practical because it suggests that odds in life can tilt into positives. Children, youth, or even adults suffering from mental health issues can be treated and directed towards normal life as before. In order to do so, one must focus on the scientific perspective of resilience as a process.

Published: October 2022

Emotions have a vital role in human beings, and it is tough to define because of their intangible nature. Emotions vary over time and from person to person. Sometimes, emotions that sound good to people also may harm human beings. It depends upon one's health conditions and circumstances. Emotions are related to neurological, physiological, or cognitive processes. Though emotions are intangible, many invasive and non-invasive techniques are available to read the electrical activity in the brain to sense the different kinds of emotions. EEG is a non-invasive technique used in brain wave analyses. The main goal of this chapter is to give a brief introduction to EEG, characteristics of the brain waves, which part of the brain is responsible for emotions, the neurological structure of emotions, and lists of deep learning algorithms used to classify the various emotions. This chapter also contains data sets of emotions and a few key challenges in this field. For researchers with engineering backgrounds who are naive to this field, this chapter could be helpful.

Published: October 2022

The aim of this research work is identification of optimum drilling parameters to increase material removal rate, dimensional and profile accuracy during drilling. ASTM A516 (Grade70) which is a boiler quality plate of 12 mm thickness was considered as the specimen for conducting the experiments. The experiment was done based on full factorial design using 18 experiments generated using Minitab Software. Two levels for tool material and three levels for feed-speed combination and cutting environment were considered. Two runs were carried out for each trial. The metal removal rate was calculated for each hole drilled. The mean result of the two runs of a trial was taken as the result of the trial. The drilled holes were then tested for their dimensional, profile accuracies. With these results in hand the Artificial Neural Network software was trained to predict the optimized input parameters for drilling a hole of required dimensional and profile accuracies and with required metal removal rate.

Published: October 2022

Dynamic light scattering (DLS) is a well-established technique to analyze particle size in a liquid medium and sample preparation is an essential step of the analysis to obtain reliable data. In this study, the pretreatment of an aqueous suspension containing betulin particles was studied to characterize the colloidal betulin particles in supramolecular hydrogels obtained by the liquid antisolvent precipitation from purified and unpurified betulin samples. Parameters of two-step homogenization process using rotor and ultrasonic homogenizer, particle concentration, and pH were systematically varied to obtain stable aqueous suspensions that meet the requirements of DLS technique for good particle size analysis. It was found that the purified betulin particles have a higher tendency to agglomerate and their suspension is stable in a narrower concentration and pH range than unpurified. Particle size analysis in suspensions prepared independently shows good reproducibility of sample preparation.

Published: October 2022

A novel approach of Micro-electrochemical Texturing (MET) is a realistic substitute for generating surface textures of machined surface. Several conventional and non-conventional techniques i.e., embossing, sand blasting, pinning, LBM, EDM etc. are available for generating microsurface textures, but creates several problems to generate microtextured surfaces which reduce the quality and lower the productivity. To overcome these limitations, this research proposes a unique microsurface texturing method namely, micro-electrochemical texturing, based on electrochemical reaction. Due to the high flexibility of the micro-electrochemical texturing system, micro-texturing features, surface roughness and its performance can be easily changed by varying the micro-electrochemical parameters. In this research paper, this process is developed to fabricate the microsurface textures on stainless steel specimens economically with less time. The experimental results of surface characteristics generated on workpiece utilizing the developed setup with vertical cross flow electrolyte circulation system in micro-electrochemical texturing method are presented. The effects of duty ratio and voltage on performance criteria i.e., material removal rate (MRR), taper kerf angle and surface roughness are investigated. The obtained overall surface roughness value on the stainless-steel samples machined by micro-electrochemical texturing technique is 0.08μm.

Authors: Bērziņa Laima , Mieriņa Inese
Published: October 2022

Oxidation is a natural part of the aerobic world. Usually oxidation is suppressed by adding various antioxidants. Although a huge amount of antioxidants is known, studies of more active antioxidants which could be used in smaller amounts are crucial. Previously we have demonstrated arylmethyl Meldrum`s acids as promising free radical scavengers. On the other hand various phenol type compounds represent one of the most diverse group of antioxidants. In this study, two types of antioxidants – 1,3-dicarbonyl and phenol – were combined in a single molecule to study the plausible synergistic effects. Vanillic acid was used as a phenolic antioxidant, and Meldrum’s acid was the 1,3-dicarbonyl type antioxidant. The target compound was synthesized in four steps, and its antiradical activity was assessed using the DPPH method. The antiradical activity of the synthesized antioxidant was higher than that of widely used BHT.

Application of the adapted methylene blue (MB) adsorption method in determining specific surface area was investigated on particles containing hydrogels obtained from purified (99 wt%) and unpurified (60 wt%) betulin samples. In order to study the adsorption isotherms of MB on betulin particles in aqueous dispersions, initial concentration of MB was varied. An analysis of the adsorption process with the Langmuir adsorption model was performed. The results indicate that the experimental data fits very well with the Langmuir adsorption model. Straight isotherms are obtained with very good determination coefficients (R2=0.99; R2=1.00), which means that the surface of purified and unpurified betulin particles is homogeneous energetically and a monomolecular coverage forms during adsorption. The MB adsorption method adapted for betulin particles is simple and requires less complex apparatus and time than other methods. The determined specific surface area can be used to characterize the surface properties of betulin particles.

A modern, healthy diet relies on ever greater consumption of fruits, vegetables and other plant-based foods, with apples being some of the most affordable and readily available fruits that in most cases can be produced locally. With the higher interest of consumers in certified organic food products, methods for testing the food authenticity are becoming of key interest. For a food product to be labelled “organic”, it must be grown in certain conditions, without the use of pesticides, herbicides and synthetic fertilizers to elevate the yield. In this study the effect of different fertilizers on the nitrogen isotope ratios and amino acid composition in apples has been evaluated. Different parts of an apple were analyzed, and it was determined that only seeds contained enough nitrogen to give reliable results on δ15NAIR values and total nitrogen content. The results of apple seed analysis with stable isotope ratio mass spectrometry (SIRMS) showed that in three out of four apple varieties, the heavier nitrogen isotope (15N) content was higher in nitrogen-fertilized apples than in non-fertilized ones. Our research did not find any statistically significant correlation between the nitrogen and carbon content in apple seeds and the fertilization regime. The relative amino acid content in apple seeds was determined by gas chromatography and it was found that there is a moderate correlation between the stable nitrogen isotope ratios in apple seeds and the relative content of alanine and tryptophan.

In this current article, an effort was made to briefly study the impact of magnesium content on the mechanical and metallurgical performance of as-cast Zn-Al-Si-Mg alloy. Zinc, aluminium, and silicon of appropriate weight quantities were melted in an electric furnace, and magnesium of varying quantities (1-5wt%) was added to the melt to obtain rectangular cast specimens. Microstructural, hardness and mechanical property analysis was conducted for the developed alloy in the as-cast condition. It was noted that an addition of Mg to the Zn matrix refines the grains but more than 3wt-% of Mg to the matrix forms clusters which deteriorate the property of the alloy in the as-cast condition. The value of hardness and tensile strength were noted to enhance, and ductility was observed to decrease from the baseline alloy to the alloy with 3wt% of Mg. Further addition of Mg decreased the properties of the alloy.

Recent past witnessed the widespread use of High Strength Low Alloy steels in several structural applications, including pressure vessels, line-pipe transportation of crude oil in the oil industry and many more. API X-65 grade is widely used as a promising material for line-pipe applications in the oil industry. HSLA X-65 plate steels are produced by normalising, Controlled Rolling (CR), Direct Quenching & Tempering (DQT) or Quenching & Tempering (Q&T) techniques. These steels are characterised by their low carbon concentration while maintaining low alloy additions. Micro alloy additions such as V, Ti, and Nb provide substantial precipitation strengthening effect. Strengthening, hardness and microstructural examinations are conducted in all the stages to ascertain X-65 HSLA steel's ageing behaviour.
Numerical Analysis of Surface Integrity in Parallel Turning Process Part II: Influence of Cutting Tool Rake Angle
Authors: Kalidasan R.
Published: October 2022

Parallel turning is one among the advanced unconventional turning process. It employs two turning tools operating concurrently to cut the material from the workpiece. For turned rotary components, surface integrity is a major quality indicator that determines the fatigue life of the finished workpiece. Tool parting distance, rake angle and edge radius affects surface integrity. Part I dealt with numerical analyses to determine the effect of parting distance on surface integrity using finite element based commercial software Abaqus 6.14. Here in Part II, the impact of rake angle over surface integrity for various cutting speeds and feeds are numerically analyzed. It was observed that with the rise in negative rake angle the negative residual stresses decreased for the machined surface of leading and lagging cutting tool. When the rake angle is increased from-10 ̊ to-2 ̊, percentage reduction of negative residual stresses is same for the turned surfaces of both tools. The cutting velocity was 250 m/min and feed 0.2 mm/rev. With the rise in rake angle, the friction angle reduced but shear angle raised. When the cutting velocity increased, the shear angle of the leading and lagging cutting tool reduced. Lower shear angle causes higher stagnation region which further causes higher compressive surface residual stress.

Published: October 2022

Context

Despite the increased risk of musculoskeletal (MSK) injury after a concussion, little is known about the determinants of such a risk. Moreover, the authors of previous reports of increased risk of MSK injury after a concussion have neglected to account for the high level of undisclosed concussions.

Objective

To explore the association between the intention to disclose a possible concussion and the intention to disclose an MSK injury.

Design

Cross-sectional study.

Setting

Online survey.

Patients or Other Participants

One hundred seven National Collegiate Athletic Association Division I athletes (females = 79%, age = 19.4 ± 1.4 years).

Main Outcome Measure(s)

Online survey exploring determinants such as injury knowledge, attitudes, perceived social norms, and perceived behavioral control surrounding concussive and MSK injury disclosure.

Results

A significant association between high intention to disclose a concussion and high intention to disclose an MSK injury (χ2 = 19.276, P < .001, Cramer V = 0.482) was observed. Spearman rank correlations suggested no correlation between concussion nondisclosure (25%) and MSK injury nondisclosure (52%). Multivariate binomial regressions indicated that perceived social norms were the strongest determinant (β = 1.365, P = .002) of high intention to disclose concussion, while attitudes toward MSK injury (β = 1.067, P = .005) and perceived social norms (β = 1.099, P = .013) were the strongest determinants of high intention to report MSK injury.

Conclusions

Individuals with high intention to report concussion symptoms also demonstrated high intention to report MSK injury. Strong positive associations were seen between known determinants of intention to disclose concussion and adapted versions of those same determinant domains in intention to disclose MSK injury. As those with high intention to disclose concussion also displayed high intention to disclose MSK injury, intention to disclose injuries generally may play a role in explaining the increase in MSK injury after a concussion.

Published: October 2022

Background and Aims:

Mask ventilation is one of the important skills required for successful airway management. Following the induction of general anaesthesia, there could be airway obstruction due to fall back of the tongue or soft palate. This obstruction could be overcome by manoeuvring the mandible or inserting airways. The primary objective of the study was to compare the efficacy of modified thenar eminence technique of mask ventilation in improving expired tidal volume (VTE) over conventional thenar eminence technique and the secondary objective was to compare peak airway pressure (PMAX) and ease of mask ventilation between the two techniques.

Methods:

Seventy-six patients were randomised into group M and group C. In group M, the modified thenar eminence technique was performed for five consecutive breaths followed by conventional technique, and vice versa was followed in group C. In each breath, VTE, PMAX and end-tidal carbon dioxide were noted. Participants reported the ease of ventilation score using the Likert scale for each technique.

Results:

VTE was significantly more in modified thenar eminence technique than conventional technique [mean ± standard deviation, 370 ± 55 ml versus 313 ± 50 ml, P = 0.01]. Ease of ventilation score [median 1.70 (interquartile range (1–2)) versus 2.3 (2–3), P = 0.01] showed that modified technique was easier compared to conventional technique.

Conclusion:

Modified thenar eminence technique of mask ventilation is superior to the conventional technique in terms of VTE and ease of ventilation in the unanticipated difficult airway.
