Published: August 2024

The government's plan to transform the Tanjung Siambang area into a tourist destination necessitates the relocation of fishermen's homes. Job diversification becomes a solution for fishermen in Tanjung Siambang to survive. Job diversification is a strategy that must be implemented by fishermen because, without it, they will face difficulties in meeting their household economic needs. Economic needs must be continually met to ensure daily life runs smoothly. The purpose of this study is to determine the impact of relocation due to the construction of resorts and golf courses on the fishing community in Dompak Island. This study uses a qualitative approach. This approach is used to describe the context of fishermen's lives in job diversification for survival. The data sources in this study are primary and secondary data obtained through observation and in-depth interviews. The results of the study show that many fishermen in Tanjung Siambang Village have diversified their jobs by working as laborers, members of the municipal police (Satpol PP), and gardening. Moreover, the roles of fishermen's wives also contribute to the economy to meet daily needs. The impact of the relocation due to development has led the community to choose side jobs to meet daily needs and create independence by starting home industries. The development of the golf course has caused the local community to lose their homes and made access to boats for fishermen more difficult. This has fostered the creativity of the local community, which is a novelty in this study.

Published: August 2024

Quantum dot solar cells are currently the subject of research in the fields of renewable energy, photovoltaics and optoelectronics, due to their advantages which enables them to overcome the limitations of traditional solar cells. The inability of ordinary solar cells to generate charge carriers, which is prevents them from contributing to generate the current in solar cells. This work focuses on modeling and simulating of Quantum Dot Solar Cells based on InAs/GaAs as well as regular type of GaAs p-i-n solar cells and to study the effect of increasing quantum dots layers at the performance of the solar cell. The low energy of the fell photons considers as one of the most difficult problems that must deal with. According to simulation data, the power conversion efficiency increases from (12.515% to 30.94%), current density rises from 16.4047 mA/cm2 for standard solar cell to 39.4775 mA/cm2) using quantum dot techniques (20-layers) compared to traditional type of GaAs solar cell. Additionally, low energy photons' absorption range edge expanded from (400 to 900 nm) for quantum technique. The results have been modeled and simulated using (SILVACO Software), which proved the power conversion efficiency of InAs/GaAs quantum dot solar cells is significantly higher than traditional (p-i-n) type about (247%)
Субсистенциализм
Authors: Ruchko S. V.
Published: August 2024

В этой книге Сергей Ручко, создатель субсистенциальной философии, предлагает дальнейшее развитие своих философских взглядов. Концептуальным противником субсистенциализма выступает экзистенциальная философия, в противовес которой он разрабатывает субсистенциальную теорию. Субсистенциализм — это философия субсистирования абсолютно автономных объектов, особенно включая объекты, субсистирующие за пределами существования человеческой реальности. Центральной инновацией субсистенциализма становится идея придания объектам субсистенции. Вводится субсистенциальный анализ таких объектов. Сергей Ручко уходит от необходимости мыслить в парадигме традиционной философии, которая устроена на фундаменте отношений. Субсистенциализм радикально отрицает наличие отношений, делает их вторичными, производными от глобальных объектов, которые субсистируют за пределами человеческой реальности, бытия, ничто или существования. Субсистенциализм — это дерзкая попытка вернуть философии ее былое величие. А вместе с ним и смелость мышления тем, кто интересуется современными дискуссиями в философии, и озадачен поисками смысла современного бытия.

Authors: Akar Bedrettin , Uğur Fatih , Kaplan Tolga , Albayrak Mehmet
Published: August 2024

Aims: To retrospectively demonstrate the effect of patellar resurfacing (PR) on the clinical and functional outcomes of total knee arthroplasty (TKA).
Methods: The files of 257 patients who presented to our clinic between 2013 and 2022 and underwent TKA due to the diagnosis of grade IV gonarthrosis were screened retrospectively. Thirty-two patients were excluded due to not attending regular follow-up, receiving steroid treatment, or being morbidly obese. The sample consisted of 225 patients, of whom 123 underwent PR (Group A) and 102 did not undergo PR (Group B). The Sperner classification was used to evaluate the level of patellar arthrosis. The effect of PR on postoperative clinical and functional outcomes in patients undergoing TKA was investigated using the WOMAC knee functional scoring and Visual Analog Scale (VAS) for clinical and functional evaluation at six, 12, and 24 months postoperatively.
Results: The presence of anterior knee pain wasstatistically significantly lower in Group A than in Group B (p=0.0001). There was no statistically significant difference between the comorbidity distributions of the groups. The preoperative-to-postoperative changes in the mean VAS and WOMAC scores were statistically significantly higher in Group A compared to Group B (p=0.0001 for both).
Conclusion: The implementation of PR in TKA may vary depending on countries, clinics, and even surgeons. In the current study, PR was found to contribute positively to the clinical and functional outcomes of patients by preventing complications such as anterior knee pain that may develop due to patellar arthrosis in the postoperative period.
Comparison of classical and anchorage methods in sacrospinous ligament fixation
Authors: Adan Ramazan , Şahin Fatih
Published: August 2024

Aims: Pelvic organ prolapse (POP) is a common condition that affects the quality of life in women. As a natural consequence of the aging population, it is believed that POP will increase in the next 40 years. With the increase in life expectancy, there is an expected rise in reconstructive surgical procedures to correct pelvic floor disorders. POP can occur in three vaginal compartments: anterior, apical, and posterior. The apical compartment includes uterine prolapse, cervix, or vaginal cuff prolapse. Our primary objective was to compare the surgical outcomes of the method using the classic technique with pelvic floor anchorage (anchoring).
Methods: This retrospective cohort study consisted of women with POP-Q (Pelvic Organ Prolapse Quarejment) grade 2 and above in the apical compartment. In the sample size calculation, G power analysis was performed with α: 0.05 and 80% accuracy. Forty-eight women were included in the study, with 24 of them undergoing the classic method and the other 24 receiving sacrospinous ligament fixation (SSLF) using a pelvic floor anchoring device. The results of both surgical methods were compared in terms of anatomical recurrence.
Results: There was no statistically significant difference observed between the postoperative measurements of the C points. However, the difference in the C level between preoperative and postoperative measurements for patients who underwent the classic SSLF operation was statistically significantly higher compared to those who underwent the Anchorage SSLF procedure.
Conclusion: When comparing the classic and anchoring systems for the SSLF procedure, no difference was observed in terms of recurrence. However, the classic method was found to be more successful in restoring apical prolapse.
Tropical Mirror

Published: August 2024

We describe the tropical curves in toric varieties and define the tropical Gromov-Witten invariants. We introduce amplitudes for the higher topological quantum mechanics (HTQM) on special trees and show that the amplitudes are equal to the tropical Gromov-Witten invariants. We show that the sum over the amplitudes in $A$-model HTQM equals the total amplitude in B-model HTQM, defined as a deformation of the $A$-model HTQM by the mirror superpotential. We derived the mirror superpotentials for the toric varieties and showed that they coincide with the superpotentials in the mirror Landau-Ginzburg theory. We construct the mirror dual states to the evaluation observables in the tropical Gromov-Witten theory.

Les « Dimettes » de Saône-et-Loire, entre insubordination et désindustrialisation (1954 au très contemporain)
Authors: Castellesi Romain
Published: August 2024

Cet article entend questionner la résistance des ouvrières de l’entreprise de sous-vêtements Dim, située dans le département de Saône-et-Loire, au phénomène de désindustrialisation, pendant le second vingtième siècle. Précocement implantée, au milieu des années 1950, l’entreprise compte jusqu’à sept usines au début des années 1970, réparties du Bourbonnais à la Bresse bourguignonne. L’entrée précoce en récession du secteur bouleverse la formation d’une génération d’ouvrières, dont les traces subsistent encore aujourd’hui dans le seul site ayant survécu au démantèlement, à Autun. Entre ces deux dates, ces « invisibles parmi les invisibles », ouvrières souvent issues d’un milieu rural, ayant rejoint tardivement la condition usinière, donnent à voir les métamorphoses de l’action ouvrière au prisme du genre et en situation de crise économique. Ces ouvrières, à l’histoire méconnue, oscillent entre insubordination et démobilisation.
Les conditions d’une contribution légitime de la CCFV à une législation sur la fin de vie
Authors: Fatin-Rouge Stéfanini Marthe
Published: August 2024

Dans le débat complexe et sensible sur la fin de vie, l’instauration d’une convention citoyenne pose la question de l’intérêt et des conditions de la légitimité d’une telle instance pour se prononcer sur un sujet de société. Intervenant parallèlement à de nombreux autres organes représentatifs, la CCFV est apparue comme l’un des rouages permettant d’enrichir le débat démocratique sur la question de la fin de vie. Tirant les leçons de l’expérience de la Convention citoyenne sur le climat, et des critiques plus générales formulées sur la manière dont cette convention avait été présentée et perçue par les citoyens, toute ambiguïté a été écartée dès l’annonce de sa mise en place quant aux objectifs assignés à la CCFV. Par ailleurs, le Comité de gouvernance et le collège des garants de la CCFV ont été particulièrement attentifs au bon déroulement de la procédure pour éviter que le processus soit décrédibilisé dans son principe même. Le rapport rendu laisse toutefois perplexe en ne formulant pas de propositions prêtes à l’emploi mais des modèles et un « nuancier d’opinions » ne permettant de dégager que des consensus plus ou moins larges sur certaines questions. Dans ces conditions, l’utilité d’une telle consultation se pose et permet de s’interroger plus largement sur la place que peut occuper une convention citoyenne parmi les institutions. Si les modalités de la composition d’une convention citoyenne visent à assurer une forme de représentation de la société, sa légitimité dépend également de son mandat et du rôle qui lui est assigné au sein du système politique et institutionnel ainsi que des garanties entourant le déroulement du processus dans son ensemble. Ces éléments pourraient faire l’objet d’une consécration par le droit de manière précise, tout en restant adaptable, pour lever la confusion actuelle concernant leur possible instrumentalisation. L’institutionnalisation des conventions citoyennes, qui permettrait de clarifier leur rôle, les conditions de leur mise en place, et les objectifs qui leur sont assignés, participeraient ainsi à la légitimation progressive de cette forme de participation citoyenne qui pour l’instant reste à un stade expérimental.

• Objectifs Cette recherche vise à discuter la relation dialogique entre agentivité et gouvernementalité des consommateurs en matière de comportement dit responsable (ici dans sa dimension durable). • Méthodologie Une étude qualitative est menée auprès de 28 jeunes Chinois et complétée par des données secondaires pour améliorer la compréhension du contexte chinois. • Résultats Quatre registres d’agentivité/gouvernementalité de la consommation durable sont identifiés : participation, conformisme, distanciation, résistance. Trois dimensions sous-tendent ces registres : le pouvoir perçu de l’État vs marché ; la confiance envers les différents dispositifs du marché vs l’État ; la diversité des expériences vécues (locales ou internationales). • Implications managériales Ce travail propose des recommandations pour accompagner des pratiques de consommation écoresponsable au regard de la capacité perçue d’agir des individus (agentivité) mais aussi de leur rapport au pouvoir des institutions (gouvernementalité). • Originalité Le principe dialogique « unit deux principes antagonistes qui sont indissociables et indispensables pour comprendre une même réalité » (E. Morin). Agentivité et gouvernementalité sont liés pour comprendre les registres de responsabilité perçue des consommateurs en matière de durabilité et orienter la décision des organisations en regard de ces derniers.
Que pensent les Français des dynamiques démographiques en France et dans le monde ?
Authors: De Luca Barrusse Virginie , Lefèvre Cécile , Véron Jacques
Published: August 2024

En 2018 a été menée l’enquête Pop Aware, dans le cadre du panel Elipss, représentatif de la population française. En étudiant tout autant les connaissances que les opinions relatives aux dynamiques démographiques, en France et dans le monde, cette enquête poursuit un double objectif : d’une part, elle reprend des questions posées des décennies plus tôt sur la situation française, permettant ainsi des comparaisons dans le temps ; d’autre part, elle introduit de nouvelles réflexions, en étendant notamment le champ de son questionnement aux enjeux mondiaux. Les enquêtés considèrent les questions démographiques comme importantes, et ce, de façon relativement indépendante des caractéristiques sociodémographiques et des opinions politiques. Ils expriment aussi une préférence pour la stabilité de la population plutôt que pour sa décroissance, malgré une augmentation des opinions liant dynamique démographique et problèmes environnementaux, notamment chez les jeunes. Ce degré élevé de sensibilité aux phénomènes démographiques est entretenu à la fois par les médias et par l’école. Il n’est pas récent. Des enquêtes de conjoncture et d'opinion publique réalisées sur une période de 60 ans le mettaient déjà en évidence. La conduite d’enquêtes similaires, dans d’autres pays comme en France, serait pertinente pour saisir d’éventuelles variations, dans l’espace et dans la durée, des manifestations de cet intérêt pour la démographie.
Dirigeants et professionnels de haut niveau : une définition statistique de l’« élite socioprofessionnelle »
Authors: Amossé Thomas , Bouchet-Valat Milan
Published: August 2024

Cet article présente le cadre théorique, la méthode de construction et les premières analyses d’une nouvelle catégorie associée à la nomenclature des professions et catégories socioprofessionnelles (PCS 2020), les « dirigeants et professionnels de haut niveau », qui vise à identifier les positions professionnelles les plus élevées au sein de la société française. Cette catégorie délimite, parmi les chef·fes d’entreprise et les cadres et professions intellectuelles supérieures, la fraction supérieure des positions (salariées ou non) caractérisées par une responsabilité importante dans les organisations de travail et/ou une expertise reconnue comme étant de haut niveau. Objectivées par un libellé d’emploi et des caractéristiques professionnelles, ces positions définissent une « élite socioprofessionnelle » (3 % de la population en emploi) qui permet de réaliser la jonction entre la sociologie de la stratification et la sociologie des élites. Mise à disposition dans les enquêtes de la statistique publique, cette catégorie contribue à renouveler l’analyse des inégalités socioprofessionnelles de façon complémentaire aux approches s’appuyant sur les plus hauts niveaux de diplôme ou de revenu. En guise de première illustration de ses possibles apports empiriques, cet article met en évidence une très forte reproduction intergénérationnelle en haut de l’espace social.

Cet article propose à titre exploratoire un modèle d’analyse de la mise en œuvre du processus complexe de production d’Intelligence Collective dans une équipe de Direction. Mobilisant une méthodologie mixte combinant Recherche-Intervention et entretiens pour la production et le traitement d’un riche corpus de données essentiellement qualitatives, il suggère qu’Interactivité Cognitive et qualité de la relation sont des antécédents de nature à favoriser l’atteinte du stade de la controverse féconde, ou « intersubjectivité contradictoire ». Celle-ci agit comme un catalyseur de la production d’Intelligence Collective potentiellement émise à partir d’une complémentarité de points de vue.
Identification des coûts cachés dans l’enseignement secondaire technique au Cameroun
Authors: Atangana Guy Christian Basile , Kamwa Cyrille Ader Kouam
Published: August 2024

Depuis 2005, le gouvernement camerounais s’est engagé dans l’approche par compétence de son système éducatif. La professionnalité exige que les élèves soient capables d’analyser leurs pratiques, de résoudre des problèmes, de mobiliser des stratégies afin d’assurer leur employabilité (Altet, 1996, 2002 ; Lenoir, 2007 ; Perrenoud, 1993). Or, l’insertion professionnelle demeure une préoccupation du gouvernement. En recherchant les processus de réussite scolaire, il serait intéressant à priori d’analyser les facteurs d’échecs. Une introspection de l’identification des coûts cachés permet de relever que des dysfonctionnements liés aux comportements humains, aux institutions et aux changements sociaux sont inhibiteurs de performance scolaire.
Les déterminants de la rentabilité des entreprises financées par « equity crowdfunding »
Authors: Meniaoui Jihène , Ben Larbi Sami
Published: August 2024

En mobilisant des arguments issus des approches actionnariale et cognitive de la gouvernance, nous proposons dans cet article d’analyser les déterminants de la rentabilité post-investissement des entreprises françaises financées par equity crowdfunding au cours de la période 2014-2020. Notre article privilégie une extension des modèles linéaires généralisés (Liang et Zeger, 1986 ; McCullagh et Nelder, 1989), recommandée lorsque l’on est en présence de données longitudinales non indépendantes. Nos résultats montrent que la rentabilité post-investissement des entreprises financées par ECF dépend à la fois du mode d’investissement proposé par les plateformes, mais aussi d’autres attributs ayant trait au profil du (ou des) porteur(s) de projet ainsi qu’à son stade de développement .

L’objectif de cet article est d’analyser l’apport des décisions de justice sur le respect de l’égalité des salaires sur une période de 25 ans en France, quel que soit le genre. Il s’agit de comprendre quel type d’égalité est mis en avant par les juges. L’approche judiciaire fait ressortir une articulation entre l’égalité formelle et l’égalité réelle en faisant appel au principe d’équité, ce qui influence les politiques managériales sur les salaires au sein des organisations.
L’accompagnement des agriculteurs/éleveurs en difficulté : le dispositif spécifique de l’association wallonne Agricall
Authors: Spoljar Philipe , Leruse Laurence
Published: August 2024

Cet article présente certaines modalités d’accompagnement spécifiques proposées par une association wallonne d’aide à des agriculteurs/éleveurs en difficulté professionnelle, et le plus souvent également personnelle. Initialement centré sur le soutien psychologique, le dispositif s’est élargi à la prise en compte des différents déterminants d’ordre organisationnel, social, économique, agronomique ou juridique impliqués dans ces situations. Sont évoquées les caractéristiques de la démarche mise en œuvre, visant la globalité et singularité des situations prises en charge, ainsi que les processus de médiation qui sous-tendent les interventions. Les dynamiques spécifiques de ces accompagnements sont ensuite analysées à partir du concept de « sollicitude », ouvrant la réflexion sur les questions de l’autonomie professionnelle et du recouvrement du « pouvoir d’agir ».

Published: August 2024

Enhancing safety protocols in train stations requires proactive approaches to foresee and reduce any mishaps. In order to maximize safety in railroad environments, this study presents a novel machine learning framework that combines neural networks with random forest techniques. This hybrid model departs from traditional single-algorithm approaches by utilizing a variety of methods to enhance accident investigation and prediction. The chapter focuses on using this hybridized method, showcasing the functions of random forests and neural networks in predicting future events and assessing accident data from the past. The strategy of incorporating neural networks (multi-layer perceptron (MLP)) and random forests into the accident analysis framework is covered in the study. It also investigates if this model can be implemented in real-time and at scale within railway station safety systems. The results of the research reveal that the hybridized machine learning approach is a promising tool for improving safety standards in railroad stations.

Authors: Gohil Ishan , Ratra Anand , Sanghavi Utkarsh , Kothari Jignesh
Published: August 2024

Isolated stenosis of the left coronary artery is extremely rare. Studies have shown a 2%–10% incidence of acute myocardial infarction in patients aged 45 years or younger. Stable angina and multivessel disease are uncommon in the young. It is more commonly reported in postmenopausal women. Here, we describe a 30-year-old female who presented to the emergency department with angina. Coronary angiography (CAG) was suggestive of isolated left main coronary artery (LMCA) ostial disease with rest of the coronaries normal. Computed tomography CAG performed with a calcium score of 0 revealed isolated osteoproximal stenosis of the LMCA. The patient was extensively evaluated for all risk factors but was devoid of any. Coronary artery bypass grafting was performed without complications.

Patent ductus arteriosus (PDA) is a common congenital heart disease, presenting with symptoms of increased pulmonary blood flow in infancy and childhood. In adults PDA if it is small detected accidentally because of the continuous murmur or if PDA is large they develop severe pulmonary vascular disease and develop Eisenmenger syndrome. Very few patients with large PDA present with dilated cardiomyopathy without pulmonary hypertension. Herewith, we report a case of large PDA who presented with symptoms of heart failure without pulmonary vascular disease and manage successfully with percutaneous device closure.

Authors: Bafna Akshay Ashok , Totawar Kuldeep , Deokate Varun , Shriwastav Rohit Ramachandra
Published: August 2024

Objective:

The objective of this study was to assess the risk factors associated with residual stenosis in patients with percutaneous transluminal coronary angioplasty (PTCA).

Materials and Methods:

A cross-sectional survey was conducted at a single health-care center among coronary artery disease patients who have undergone PTCA. Primary information including demographics and clinical characteristics, groups of pre- and postdilation balloons, and characteristics of culprits’ vessel flow were retrieved from medical records of each patient. Data were analyzed using descriptive and appropriate comparative statistics.

Results:

A total of 1000 patients were included in this study. The majority of patients were men (67.0%). Hypertension (HTN) and diabetes were the most common comorbid condition. Yukon Choice phosphorylcholine (PC)-elite (86.2%) was the most common stent used in patients with PTCA followed by Endeavor Sprint (12.7%). All of the patients (100%) underwent PTCA for single culprit vessel disease (SVD) while 30.2% of the patients underwent PTCA for two-vessel disease (2VD). The incidence of residual stenosis was 0.5% for SVD PTCA and 0.3% for 2VD PTCA. The 2VD group achieved thrombolysis in myocardial infarction flow Grade II postrevascularization in 98.6% of patients. Significant associations were observed between residual stenosis and various factors. HTN (odds ratio [OR]: 38.79, 95% confidence interval [CI]: 3.260-461.688; P = 0.004), diabetes mellitus (OR: 4.548, 95% CI: 0.036-63.948; P < 0.001), the use of a 0.014” × 190 cm guide (OR: 185.0, 95% CI: 25.922-1320.294; P < 0.001), and the presence of two-vessel disease (OR: 6.698, 95% CI: 1.221-36.749; P = 0.029) were found to be significantly associated with residual stenosis.

Conclusion:

Residual stenosis was observed in both SVD and 2VD PTCA however, presence of HTN and DM, and 2VD were identified as pronounced risk factors for residual stenosis.
Premenopausal and postmenopausal women presenting with acute coronary syndrome: A comparison study of their clinical and angiographic profiles
Authors: Goswami Saurabh , Mohabansi Swapnil , Anoumandane Selvabharathi
Published: August 2024

Context:

Acute coronary syndrome (ACS) encompasses a range of conditions associated with sudden, reduced blood flow to the heart, typically due to an acute blockage of a coronary artery. The severity and specific location of the blockage determine the type of ACS and its consequences. Menopause, marked by a significant decline in estrogen levels, is known to negatively impact circulatory function and metabolism, potentially increasing the risk of ACS. However, there is a lack of studies comparing the burden of cardiovascular disease between pre- and postmenopausal women.

Aim:

This study seeks to bridge the knowledge gap regarding the impact of menopausal status on the presentation and severity of ACS in women.

Setting and Design:

This retrospective observational study was conducted in a single center, India, over 7 months.

Materials and Methods:

The study included 250 patient populations among which 120 were premenopausal and 130 were postmenopausal women. The subjects were evaluated for their clinical and angiographic profile.

Statistical Analysis Used:

Differences between pre- and postmenopausal women were compared using the two-sample t-test for continuous variables and the Chi-square test for categorical variables.

Results:

In this study, the mean ± standard deviation number of stenotic vessels and Gensini score was significantly higher in postmenopausal patients (2.46 ± 0.74 and 47.35 ± 20.92, respectively) than in premenopausal patients (1.30 ± 0.27 and 13.13 ± 4.43, respectively) which indicate the severity of coronary artery disease in postmenopausal women.

Conclusion:

Menopausal status significantly impacts the severity of coronary artery disease (CAD) in women presenting with ACS, as demonstrated by the marked difference in Gensini scores.

Published: August 2024

Background and Objectives:

Thoracic trauma in children is increasing due to rising population, industrialization, modernization, increase in vehicular traffic, terrorist activities, and riots. It requires more caution because of its associated morbidity and mortality. This study is done to know the prognostic factors and outcome of thoracic trauma in children, which helps in decreasing morbidity and mortality.

Materials and Methods:

This retrospective observational study was conducted from November 2016 to October 2022. Retrospectively, records of all the pediatric patients <18 years of age with a history of thoracic trauma were analyzed. Demographic details, mechanism of injury, nature of the injury, hemodynamic stability, investigations, definitive treatment, and outcome of patients were analyzed.

Results:

There were 66 children with thoracic trauma. Road traffic accidents were the most common mode of trauma seen in 74.2% of cases, followed by falls in 18.2% of cases. Fifteen (22.7%) cases were hemodynamically unstable. Thirty-two (48.5%) cases required transfusion of blood or blood products. Penetrating trauma was seen in 10 (15.2%) cases. In children with thoracic trauma, up to 29 (43.9%) children had pneumothorax and 21 (31.8%) children had hemothorax. Among the injuries, lung contusions were more commonly seen in 31 (46.9%) cases, followed by rib fractures seen in 24 (36.4%) cases. About 83.3% of cases were managed nonoperatively and 16.7% of cases required surgical intervention. Ten (15.5%) children with thoracic trauma were succumbed to the death. Among the factors leading to mortality delayed presentation and management (50%), hemodynamic instability (100%) patients, requirement of transfusion (100%), penetrating trauma (80%), higher grade of injury (80%), and surgical intervention (80%) were identified to had poor outcome increasing mortality. Site and mechanism of injury are the other factors contributing to and deciding outcomes in pediatric thoracic trauma.

Conclusion:

Factors such as delayed presentation, hemodynamic instability, penetrating trauma, mediastinal structure injury, higher grade of injury, and surgical intervention had poor outcomes.

Published: August 2024

Coronavirus coronavirus-related (severe acute respiratory syndrome-corona virus-2) global pandemic has caused significant mortality and morbidity globally in the last 3 years. Although the pandemic has weaned off since last year, we are not in great peace of relief due to lingering effects of COVID-19 persisted even after 2 years of illness. These long COVID-19 manifestations are documented selected cases of COVID-19 pneumonia in pulmonary and extrapulmonary systems with variable impact on quality of life. In the present case report, a 57-year-old male, presented in the outdoor unit for shortness of breath on exertion, on oxygen supplementation at home during ambulation with a history of severe COVID-19 pneumonia resulted in acute respiratory distress syndrome with hospitalization in the intensive care unit 12 months back and required high flow nasal cannula with noninvasive ventilatory support for 3 weeks. His clinical and radiological severity were very well correlated with highly raised inflammatory markers such as C-reactive protein, interleukin-6, ferritin, lactate dehydrogenase, and D-Dimer. He was offered oxygen supplementation at home with antifibrotics for 3 months and observed significant improvement in clinical and radiological outcomes with persistent requirement of oxygen during ambulation and persistent respiratory symptoms even after 1 year of discharge from hospital. Rheumatological workup documented antinuclear antibody (ANA) and rheumatoid factor positive with inconclusive ANA profile reports. His high-resolution computerized tomography thorax documented at 1 year of discharge from the hospital revealed typical interstitial opacities labeled as progressive residual lung abnormalities (PRLAs) which are predominantly reticular and linear opacities in peripheral parts of lungs with honeycombing within typical pleural-based areas with parenchymal bands and altered lung architecture and decreased lung volume in both lungs. Honeycombing is a typical feature of progressive type of RLAs. We recommend these radiological outcome phenotypes as progressive radiological abnormalities (RLAs) at 1 year should be considered pulmonary fibrosis of unclassified type from a pulmonologist perspective due to pattern and presentation after COVID-19 which is not enrolled into interstitial lung disease classification as of now and progressive pulmonary fibrosis as per radiologists’ perspective due to progressive nature of the disease.

It also provides practical insights for implementation and highlights the transformative potential of such education in shaping the future of African nations.
Advancing Young Learners’ Scientific Literacy Through School Media Resource Centres
Authors: Ekeh Martin Chukwudi
Published: August 2024

This qualitative study explores the state of school media resource centres (SMRCs) and their impact on fostering scientific literacy among early-grade learners in Staff Primary Schools. Perspectives of primary school librarians were gathered through photovoice methodology and semi-structured interviews from four selected schools within Owerri Education Zone 1, Nigeria. Thematic analysis was employed to scrutinise the data, ensuring credibility and trustworthiness through member checking and triangulation. Findings reveal a glaring absence of functional SMRCs despite the presence of school libraries, impeding effective teaching and learning processes. Librarians expressed the significance of SMRCs in advancing scientific literacy, yet perceived constraints hinder their efficacy. Challenges include inadequate funding, technological infrastructure, security concerns, and outdated resources. Recommendations highlight the necessity for prioritised financing, professional development opportunities, and collaboration with external stakeholders to enhance SMRCs. Moreover, addressing electricity-related challenges, updating library collections, strengthening security measures, involving parents, and implementing talent development programmes are crucial. In conclusion, the absence of functional SMRCs in staff primary schools significantly impedes the progress and holistic development of scientific literacy of early-grade learners. Addressing these deficiencies is imperative to foster scientific literacy and ensure quality education in the 21st century.

Published: August 2024

Teaching physical sciences in English as the Language of Learning and Teaching (LOLT) has presented numerous challenges, particularly for learners who are not proficient in the language. The South African government is increasingly considering the use of indigenous languages as the medium of instruction for subjects such as physical sciences, sparking debates regarding the effectiveness of indigenous languages in teaching and learning. This study aimed to explore stakeholders' perceptions regarding the use of Tshivenḓa scientific language for the concept of electricity. Utilizing qualitative interpretative case study methodology, the researcher conducted interviews with two grade 10 teachers, three parents, and two groups of grade 10 learners from selected schools to investigate their views on using Tshivenḓa scientific language register to teach physical sciences. The findings indicate that stakeholders view the adoption of scientific language registers in Tshivenḓa as a positive initiative. They believe it will provide learners who struggle to understand physical sciences when taught in English with an opportunity to learn effectively in a language they are familiar with. Therefore, the study recommends expanding the development of scientific registers in Tshivenḓa to cover other topics in physical sciences.
From scriptor to promptor: An evaluation of the status of authorship, authenticity, and creativity in light of the use of artificial intelligence in screenwriting
Authors: Gürsoy Ali Özgür , Şavk Serkan
Published: August 2024

The disruptive potential of generative artificial intelligence in creative fields is clear, but how this will unfold remains uncertain. A key concern is that the problematic distinction between the original and the fake is going to become further blurred. In this study, we draw on a number of philosophical theories on the nature of language to set up a conceptual framework within which one can analyze the status of authorship and originality in the operation of generative AI. We argue that two conceptual orientations, namely deconstruction and genealogy, converge on the claim that authorship should be seen as always already a co-authorship. We use this conceptual framework to interpret the results of a classroom experiment with generative AI in producing screenplay loglines and synopses. Our findings suggest that we must improve students' critical skills to foster responsible self-expression in creative production, thereby unlocking the potential of human – AI interaction.

Published: August 2024

Bacterial contamination is a major problem that needs to be addressed in fungal culture. Therefore, a novel technique, cabin sequestering (CS), eliminates bacterial contamination of aquatic fungal cultures. Two treatment groups were formed, which were Group A (CS method) and Group B (subculture on antibiotic-free media) to evaluate the effectiveness of the CS method. A sterile inoculation needle was used to pierce a square hole approximately 3-5 mm in diameter, referred to as a "cabin". Then a coverslip was placed over the inoculated site at 20-30̊ C for 7-10 days. Fungal hyphae were selected and re-inoculated onto new PDA culture plates when they had grown beyond the edge of the coverslip. The result showed no bacterial growth in group A. Meanwhile, in group B, bacteria were present, but no fungal growth was detected. The CS method is advantageous because it eliminates the risk of contamination, takes less time, and requires only simple procedures using standard and easily accessible equipment.
SCREENING OF MICROBIAL BIOPESTICIDES AGAINST POST-HARVEST FUNGAL PATHOGEN COLLETOTRICHUM SPP A PRELIMINARY STUDY
Authors: KANNAPPATHY PUGANESWARY , ALIAS AMIRAH
Published: August 2024

Most common fungal pathogens are found in Colletotrichum genus which cause economically significant anthracnose or blight disease in a variety of tropical and subtropical fruit and vegetables. Despite that, the excessive application of chemical pesticides in agriculture has caused many problems such as poor soil fertility, pollution and risk to human health due to the toxic accumulation of the pesticides in the soil. This study was carried out to isolate potential bacterial colonies from five different soil sources around Universiti Malaysia Terengganu and to the screen isolated bacteria for antagonistic effect against Colletotrichum species. In total, 50 bacterial strains were isolated and subjected to selective screening to distinguish bacterial strains capable of inhibiting Colletotrichum sp. Based on the selective screening, nine bacterial strains with different morphology were selected and tested further in quantitative screening by calculating their percentage of inhibition of radial growth (PIRG). The results showed that S5-H strain demonstrated the highest inhibition effect at (75.67 ±2.86)%, followed by S5-I strain (68.89 ±5.93)%, S5-D strain (66.89 ±6.15)%, S3-C strain (60.33 ±3.19)%, S5-F strain (57.89 ±4.66)%, S5-G strain (53 ±5.79)%, S2-I strain (41.33 ±7.26)%, S4-B strain (40 ±7.07)% and S3-D strain (38.33 ±8.90)%. Based on the results, bacterial isolate S5-H with yellow, round, convex and entire colony from mangrove muddy sediment was shown to have a potential to be utilized as biopesticides against Colletotrichum sp. Nevertheless, this study requires further work in the future focusing on species identification by 16S rRNA phylogeny and mechanism of action exhibited by S5-H strain.
