Authors: León Isidro Humberto Almeyda , Quibrera Cynthia Guadalupe Rodríguez , Pecina Eleazar López , Ojeda María Genoveva Álvarez
Published: October 2024

El Huanglongbing (HLB) o enverdecimiento de los cítricos es una patología devastadora a nivel mundial. Su diagnóstico se realiza mediante la sintomatología que presentan las hojas y frutos, así como por métodos moleculares, estos últimos son específicos y sensibles. Por otra parte, están los métodos inmunoenzimáticos que son económicos, rápidos y sensibles, pero actualmente esta técnica no ha sido estandarizada para el diagnóstico de HLB. El objetivo de este trabajo fue: Producir anticuerpos policlonales IgY anti-CaLas en gallinas (Leghorn), a partir del antígeno C6XFB8 para su posible implementación en un método de diagnóstico inmunoenzímatico.  La producción de anticuerpos policlonales IgY se realizó inmunizando a gallinas con 50 µg/ml del antígeno C6XFB8, diluido en 50 µl/ml de solución fisiológica estéril y 50 µg/ml del adyuvante completo de Freund. Las gallinas fueron inoculadas subsecuentemente hasta los 75 días con un intervalo de 15 días con la misma concentración del antígeno, pero a diferencia de la primera inmunización se utilizó adyuvante incompleto. Después de cada inmunización, se colectaron los huevos y se extrajo la yema. Los anticuerpos se purificaron y posteriormente se cuantificaron por el método de Bradford. La evaluación de pureza se realizó mediante perfil electroforético y western blot. Se obtuvieron valores de 1.35 a 1.78 mg/ml en las primeras inmunizaciones, y fueron aumentando después de las post inmunizaciones de 2.46 a 2.51 mg/ml de IgY anti-Ca.Las, los cuales son valores que se consideran adecuados para su uso en el desarrollo de un método inmunoenzimático para la detección de Ca.Las.

Published: October 2024

The reproductive activity of Calliptamus barbarus and Calliptamus wattenwylianus was investigated to understand population dynamics and reproductive potential in a subhumid bioclimatic zone. Specimens were collected from July to October and dissected to assess ovarian development and egg-laying activity. The number of ovarioles, determined at birth, ranged from 62 to 67 for C. wattenwylianus and 48 to 58 for C. barbarus. Higher fertility was observed in C. wattenwylianus, with egg production increasing during the first oviposition for both species. The average reproductive yield was notable for C. barbarus (85.99%) and C. wattenwylianus (86.56%).
Oocyte resorption occurred mainly during drought (August-September) and cold periods (October-November). C. wattenwylianus females reached maturity earlier, beginning in August, compared to C. barbarus. Egg production began in July for C. wattenwylianus and in September for C. barbarus. Oocyte retention rates were 5% for C. barbarus and 9% for C. wattenwylianus.
These findings provide insights into reproductive patterns in North African Orthoptera, with implications for pest control in subhumid regions.

Authors: Özbek Murat , Paksoy Erbaydar Nüket
Published: October 2024

Küresel ölçekteki ilk 10 ölüm sebebi, tüm ölümlerin yarısından fazlasını oluşturmaktadır. Böbrek hastalıkları 2000 yılında bu listede 13. sıradayken, 2019’da 10. sıraya yükselmiştir. Kronik böbrek hastalığı (KBH) düzey 3 ölüm nedenleri listesinde 14. sıradan 11’e yükselmiş olup 2040’ta 5. sıraya çıkacağı öngörülmektedir. Dünyada 2010’da böbrek replasman tedavisi (BRT) alan hasta sayısı 2,6 milyon olup milyon nüfus başına 379 kişi olarak hesaplanmıştır. Bu sayının 2017’de 3,9 milyona yükseldiği, 2030’da 5,4 milyona çıkacağı tahmin edilmektedir. BRT’lerden biri olan böbrek nakli için düşük sosyoekonomik durum gibi bazı güçlükler bulunmaktadır. BRT’ye erişimin sınırlı kalmasıyla her yıl 2 milyondan fazla insan yaşamını yitirmekte ve bu ölümlerin çoğu düşük ve orta-düşük gelirli ülkelerde meydana gelmektedir. KBH, bireyin yaşam kalitesini düşürmekte, psikososyal sorunlarını artırmakta ve istihdamla ilgili önemli sorunlara yol açmaktadır. Ayrıca istihdam sadece KBH’den değil, hemodiyaliz/periton diyalizinden de olumsuz etkilenmektedir. KBH yüksek tedavi maliyetlerine ve azalan iş gücü nedeniyle üretkenlik kaybına da yol açmaktadır. KBH ekonomik, iş gücü, yaşam kalitesi ve yüke dair bazı hızlarla değerlendirildiğinde; küresel yükünün arttığı ve BRT’nin mutlaka göz önünde bulundurulması gerektiği bildirilmektedir. Bu derleme ile KBH yükünün küresel öneminin incelenmesi, verilerle Türkiye’deki yeri, konunun artan öneminin vurgulanarak sağlık profesyonellerinin ve karar vericilerin dikkatinin çekilmesi amaçlanmıştır.

منهجية التعامل مع التحديات المعاصرة التي تواجه الأسرة المسلمة
Authors: العلواني زينب
Published: October 2024

في خضم التطورات العلمية والتكنولوجية المتسارعة التي يشهدها عالمنا المعاصر، تبرز قضية بنوك الحليب كإحدى القضايا الشائكة التي تثير جدلاً واسعاً في الأوساط الفقهية والطبية والأخلاقية ولا سيما في المجتمعات الغربية. وتكمن أهمية هذه القضية في كونها تمس جوهر العلاقات الإنسانية والأسرية، وتطرح تساؤلات عميقة حول مفهوم الإنسان وكرامته في عصر التقدم العلمي. وتكتسب هذه القضية أهمية متزايدة في ظل التطورات التكنولوجية الحديثة وما تفرضه من تحديات على المنظومة القيمية والأخلاقية للمجتمعات الإسلامية. إن الجدل الدائر حول مشروعية بنوك الحليب يعكس في جوهره صراعاً أعمق بين رؤيتين متباينتين: رؤية تستند إلى المرجعية الإسلامية في فهم العلاقات الإنسانية والأسرية، ورؤية أخرى تنطلق من منظور مادي علماني يتعامل مع جسد الإنسان وأعضائه بوصفها سلعاً قابلة للتداول. وفي سياق هذا الجدل، يبرز سؤال جوهري: هل يمكن اعتبار حليب الأم مجرد مادة بيولوجية منفصلة عن هويتها الشخصية بمجرد انفصاله عنها؟ إن الإجابة على هذا السؤال تتجاوز البعد الفقهي، لتلامس قضايا فلسفية وأخلاقية عميقة تتعلق بمفهوم الإنسان وكرامته.

Published: October 2024

Spatiotemporal manipulation of ultrashort laser pulses is crucial for enhancing laser processing and phonon generation. Optimization of these applications requires ultrafast visualization of the underlying processes. In this study, we induced laser ablation using spatiotemporally manipulated double pulses focused from two angles onto a glass surface with a 0.7 ps interval, and captured the images of its dynamics with 5 sequential frames at a frame interval of 0.8 ps. The observed dynamics suggest that the laser profile reflected on the glass surface is influenced by its topography, which in turn affects the behavior of air breakdown plasmas.

Mainstreaming Social Realism in Children’s Literature
Authors: Benjamin Ngantchou Yongsi
Published: October 2024

Childhood is the base for human growth and development and it shall be prudent if the child has an opportunity to get exposed to the challenges and realities of life along with fantasy, ecstasy and imagination. Children can grasp and learn their environment right from an early age as they are really smart; but the supplement which reaches them in terms of literature in any form should also provide them with glimpses of real life. Hence, it would be really judicious if the fodder they get in terms of literature is infused with social realism so that they understand the realities of life, the kind of society they live in with all kinds of inequities, stigma, discrimination, cruelties, marginalisation, and social exclusion, and so on. Children shall develop the wisdom to distinguish just from unjust and in a way might also build up their responding, assertion and decision-making skills. The Paper primarily discusses how social realism needs to be mainstreamed in children’s literature, firmly believing that it shall help the children towards their own positive development along with the development of the communities and nations they live in.

Published: October 2024

Objective: The aim of this study was to assess the association between oculo-orbital CT scan results and Ocular Trauma Score (OTS) in open globe injuries. Methods: In 65 eyes with open globe injuries undergoing oculo-orbital CT, they were classified into 5 major types: intraocular foreign body/air, scleral irregularity with decreased globe volume, lens dislocation, abnormal vitreous density, choroid layer thickening, and choroidal detachment. The association between different types and the number of CT findings with OTS stages was evaluated. Results: The average age of patients was 37 ± 15.8 years. The most common CT findings were the presence of intraocular foreign bodies (63.1%), severe scleral irregularity (18.5%), and abnormal vitreous density (23.1%). The most frequent OTS stages were III (47.7%) and II (21.5%). Univariate analysis showed that severe scleral irregularity (OR = 0.015; p = 0.001), abnormal vitreous density (OR = 0.095; p < 0.004), choroidal layer thickening (OR = 0.211; p = 0.006), and foreign body (OR = 9.50; p = 0.004) were associated with more advanced OTS stages (I and II). The discovery of more anomalies on CT was associated with severe ocular injuries, namely OTS I (p < 0.001) with corresponding low final visual acuity. Conclusion: CT results can aid in predicting OTS stage and visual prognosis in open globe eye injuries.

Published: October 2024

This paper examines the phenomenon of "supply creates its own demand" in the context of Jammu and Kashmir's economy. Originally posited by Jean-Baptiste Say, this economic principle asserts that the production of goods and services leads to the generation of income and demand for those same goods and services. In this study, we aim to explore how this phenomenon unfolds within the unique socio-political, geographical, and economic landscape of Jammu and Kashmir. By analyzing key sectors such as agriculture, industry, and tourism, we assess how production drives demand and evaluate factors inhibiting this dynamic, including political instability and infrastructural challenges. A regression analysis is used to provide empirical insights, followed by policy recommendations that could enhance the region's economic growth.
Overview of Financial Efficiency in India’s Power Sector
Authors: Kalyan Dr. Nalla Bala
Published: October 2024

Power is an important tool for economic growth of the country. Power is vital for every form of human activity-domestic, agricultural and industrial infrastructure, such as telecommunication and transport. The demand for electricity in India is enormous and is growing steadily. This growth has been slower than a country’s economic growth. The big challenge of the power industry is to balance the demand and supply of electricity. Financial management involves planning, organizing, directing, and controlling the financial activities of an organization. Its primary goal is to maximize shareholder wealth and ensure the efficient use of resources. Financial efficiency refers to how effectively an organization utilizes its resources to generate revenue or profits. It involves minimizing costs and maximizing output or outcomes relative to inputs. The financial efficiency of India's power sector is a critical aspect of its energy infrastructure, impacting both economic growth and sustainability. The main needs of the study are the source and use of funds of the company and how to evaluate the financial performance of the company. The objective of this study is to critically evaluate and assess the financial performance of Southern Power Distribution Company of Andhra Pradesh State Limited, Tirupati.
Community members’ perspective on social accountability in the health system: a cross- sectional study from Tanzania
Authors: Hemgren Sigås Ebba , Kapuya Hussein , Maluka Stephen , Hurtig Anna-Karin , San Sebastián Miguel
Published: October 2024

Introduction: Social accountability initiatives are considered a way to address inefficiencies and improve overall health system performance. Tanzania has introduced Health Facility Governing Committees (HFGCs) to improve social accountability of the health system. However, information on how communities perceive these committees is lacking.  This study aimed to assess the prevalence and social determinants of the HFGCs accountability from the community perspective in Tanzania.
Methods: The research employed a cross-sectional survey design in two Tanzanian districts (Handeni and Mbarali) selected for their contrasting health performance. Data collection took place from July to October 2022, involving 1184 households in 31 villages/mitaa. The study measured social accountability through a set of six questions, focusing on community support, sensitization, feedback, trust, engagement, and overall accountability of HFGCs. Socio-demographic data such as sex, age, education, occupation, type of health facility and district were also collected and analyzed using linear regression to identify factors influencing perceptions of accountability.
Results: The findings revealed a low prevalence of social accountability as measured by the variables of community awareness and engagement with the HFGCs. Only a small percentage of respondents felt adequately informed or involved in the activities of these committees. Social determinants such as higher education levels and certain occupations, such as business and retirement and those living in Handeni district, correlated positively with a better perception of social accountability.
Conclusion: The study highlights significant challenges in the operational effectiveness of HFGCs in Tanzania, with a notable disconnect between these bodies and the communities they serve. Despite the theoretical framework for social accountability, actual community engagement remains low, impacting the overall efficacy of health governance at the local level. Future research should focus on improving community awareness and participation in these committees to improve their functionality and accountability, thereby aligning with national health objectives and local needs.
Towards a Decolonial Philosophical Theology
Authors: Meylahn Johann-Albrecht
Published: October 2024

The conversation between theology and philosophy in Africa, and more specifically South Africa, can be interpreted from different points of view, either ideally or realistically. Realistically, in the sense that South Africa is part of a global world, so global trends, for various reasons, have an impact on the local conversation, which should ideally be a lot more local and focused on the local philosophical and theological traditions. In this chapter, I will focus on a specific global trend, view this trend critically from a philosophical and theological perspective, and thereby propose a relationship between theology and philosophy that might be relevant to the decolonial South African perspective. The trend that I will focus on, which I will argue is a specifically Western trend, has an impact on South African academia.
The Hidden Face of Christ: Chesterton and the Concealment of (Divine) Mirth
Authors: Reyburn Duncan
Published: October 2024

Søren Kierkegaard tells a parable of a fire that breaks out backstage in a theatre.1 A clown charges out onto the stage to warn the audience of the danger but, because he is already dressed up for his show, the audience members mistake his warning for comedy. They laugh and clap and ultimately fail to respond to the real threat he is trying to save them from. Kierkegaard speculates that the world is likely to end “amid general applause” like this because so many people believe that what they are witnessing is only “a joke.” Considering this more deeply, in this story, Kierkegaard sets up a distinction – along soteriological lines – between what appears and what may be concealed by appearance. It seems to me that Kierkegaard means this distinction between the apparent and the hidden to be the fundamental issue at play. His clown is perhaps a symbol of Christ, the light that shines without the darkness comprehending it.2 Another reading of his parable would suggest that Kierkegaard has granted a deeper ontological importance to seriousness and a lesser significance to hilarity. After all, the crowd misses the truth precisely because

Published: October 2024

Spinal diseases are among the most prevalent health issues in modern society, significantly impacting patients’ quality of life. Diagnosing conditions such as disc herniation and spinal deformity requires advanced medical imaging techniques, including X-rays, magnetic resonance imaging (MRI), computed tomography, and nuclear magnetic resonance. Spine MRI is particularly crucial due to its ability to provide high-resolution images of soft tissues, essential for accurate diagnosis. However, the manual segmentation of spine MRI images is labor-intensive and inadequate for large-scale quantitative analysis. Thus, developing automated spinal MRI segmentation methods is critical to alleviating doctors’ workload and enhancing diagnostic efficiency. In this study, we propose a novel asymmetric U-Net architecture designed to improve the precision of reconstructing complex structures and details by increasing the depth of the upsampling side. The model incorporates adjacent-scale skip connections to control parameters while maintaining high segmentation accuracy. In addition, residual connections on the upsampling side prevent gradient vanishing, thereby enhancing the network’s feature learning and representation capabilities. Experimental results indicate that this method significantly reduces training time and increases model accuracy compared to traditional approaches, marking a substantial advancement in automated spinal MRI segmentation. This innovative approach holds promise for improving clinical outcomes and optimizing the workflow in medical imaging departments.
Minimalist approach to left atrial appendage occlusion through three-dimensional intracardiac echocardiography: Procedural steps and single-center experience
Authors: Chaudhary Ashok , Trovato John , Subodh Ragitha
Published: October 2024

Atrial fibrillation (AF), the most prevalent arrhythmia worldwide, is associated with an annual risk of ischemic stroke of up to 5%, with approximately 98% of thrombi originating from the left atrial appendage (LAA). Direct oral anticoagulants or vitamin K antagonists remain the gold standard for preventing systemic thromboembolism in patients with AF. LAA occlusion (LAAO) is an alternative stroke prevention technique for patients with AF who cannot tolerate long-term anticoagulation. Percutaneous LAAO typically employs a multimodal imaging approach with contrast fluoroscopy and transesophageal echocardiography (TEE) for visualization, device selection and deployment, and complication monitoring. TEE is also used for follow-up imaging. However, it necessitates general anesthesia or deep sedation and is associated with a high risk of adverse events. Three-dimensional intracardiac echocardiography (3D ICE) has been proposed as a viable alternative to TEE for LAAO procedures. In this review, we summarized the current evidence regarding ICE guidance in LAAO procedures. We also presented a case series of consecutive patients presenting at our center who underwent LAAO, which was performed by a single operator using a minimalist approach of moderate sedation, 3D ICE, and same-day discharge. We also presented a summary of the minimalist approach to LAAO using 3D ICE and detailed procedural steps of 3D ICE catheter manipulation for successful LAAO intervention.

Examining the psychopathology of patients who have contracted coronavirus disease 2019 remains important. The current study aims to investigate the relationship between depression, cognitive and executive functions, and their impact on quality of life. First, a comprehensive bibliographic review of relevant scientific articles and studies was carried out. Data were then collected using weighted and appropriate questionnaires. Analysis of variance and multiple regression analyses were conducted to examine the relationship between the independent variables (depression, cognitive and executive functions, and demographic factors) and the dependent variable (quality of life), to interpret and analyze the resulting associations. In contrast to depression, cognitive and executive functions did not appear to significantly influence patients’ quality of life and well-being. Further scientific research is necessary to explore these factors and their potential effects more thoroughly.

The effective operation of high-speed tracked vehicles in a combat vehicle configuration depends primarily on the correct identification of the expected operating conditions, already in the design or modernisation phase. This applies to both terrain, meteorological and climatic conditions. This approach considers the most unfavourable driving conditions and the level of dynamic loads acting on the vehicle hull, crew and equipment when making calculations. The dominant source of dynamic loads is movement at high speed on unpaved roads, off-road and when overcoming natural and artificial terrain obstacles of a predetermined or random nature. An important system responsible for the safety and reliability of this type of vehicle is the suspension. An appropriate design of the suspension parameters allows to reduce the negative dynamic loads (research hypothesis). The aim of the research was to develop a preliminary project of an initial suspension element – a hydropneumatic spring for a high-speed tracked vehicle - that allows minimising dynamic loads. The study used both theoretical and empirical research methods, including analysis, synthesis, deduction, induction, comparison and inference. The paper presents selected issues from the suspension design process for a high-speed tracked vehicle equipped with a hydropneumatic suspension. The problem was solved in three stages. In the first stage, the design of the hydropneumatic suspension unit, placed in the control arm, was made and the basic parameters were selected. In the second, the spring characteristic of the hydropneumatic unit was determined on the example of a hypothetical vehicle with assumed tactical and technical parameters. In the third stage, the strength of the control arm structure, under the heaviest load conditions, was checked using the Finite Element Method (FEM). The results obtained showed that the advantages of the hydropneumatic suspension, such as: progressive spring characteristics, improved vibration damping, possibility of introducing a semi-active or active suspension system, modularity of the structure and ease of maintenance and repair, make it more and more widely used in modern high-speed tracked vehicles.

Największym zagrożeniem dla bezpieczeństwa życia i zdrowia dziecka umieszczonego w foteliku bezpieczeństwa jest w dalszym ciągu źle dobrany i zamontowany fotelik w pojeździe. Foteliki bezpieczeństwa są uważane za główny sposób na zmniejszenie ryzyka obrażeń podczas zdarzenia drogowego. Mimo to, większość rodziców używa nieprawidłowo zainstalowanych fotelików. Nieprawidłowo dobrane i zamontowane foteliki bezpieczeństwa mogą stwarzać ryzyko obrażeń u dzieci w razie wypadku. Celem artykułu jest poprawa bezpieczeństwa dzieci przewożonych w fotelikach przez identyfikację i określenie wpływu różnych, często nieoczywistych czynników na wybór fotelika bezpieczeństwa dokonywany przez rodziców/opiekunów prawnych dziecka. W tym celu przeprowadzono ankietę na grupie 950 osób, aby poznać zachowania rodziców i opiekunów prawnych związane z zakupem fotelika bezpieczeństwa. Ankietowani mieli za zadanie odpowiedzieć na pytania związane z czasem podróży, miejscem mocowania fotelika czy dotyczących ich osobistych preferencji związanych z miejscem zamieszkania czy wiekiem. Warto zaznaczyć, że aż 357 respondentów zdecydowanie nie kupiłoby ponownie posiadanego fotelika bezpieczeństwa. Ponadto poziom bezpieczeństwa fotelika określony wynikami z testów zderzeniowych jest ważnym argumentem zakupu dla 21,88% ankietowanych kobiet i 35,66% ankietowanych mężczyzn.

The relevance of the study lies in the fact that in the context of armed aggression against Ukraine, the most scientifically relevant issues are those related to the security and defense sector, and the development of effective practical recommendations in this area is impossible without proper theoretical substantiation. The purpose of the study was to determine certain aspects of the use of methodological tools in conducting legal research in this area. To achieve its purpose and objectives, the author used general scientific and special research methods. The main results of the study are the argumentation of the position that at the present stage, the most reliable and objective legal knowledge should be considered that which involves the use of special methods, techniques and compliance with the principles of knowledge acquisition. Today, the system of legal sciences is gradually developing its own methodology based on the general scientific principles of knowledge; legal science forms it in close connection with and in accordance with the subject matter of research, reflecting the peculiarities of the object of study and its specifics. The security and defense sector, in turn, also requires a separate scientific approach and research tools, since the activities of the State in this sector, which are its exclusive prerogative, involve ensuring the sovereignty of the State, its independence in the international arena, and protection of the population on its territory. The conclusions of the study are that the system of legal sciences in Ukraine is gradually developing its own methodology in accordance with the peculiarities of the object under study and the area in which it realizes its tasks. The research is devoted to the study of an issue which is of topical importance both for the practical activities of state bodies performing functions in the security and defense sector and for further scientific research.

W pracy przedstawiono następujący problem badawczy: czy przyjęcie holizmu jako koncepcji filozoficznej może być fundamentem opracowania teorii i rozwoju logistyki wojskowej. Postawiono hipotezę, że przyczyną powolnego rozwoju teorii logistyki wojskowej jest mniejsze zainteresowanie autorów sformalizowaną logiką na bazie której można rozwijać logistykę teoretyczną. Badania prezentowane w artykule wypełniają lukę badawczą w zakresie poszukiwania podstaw teorii logistyki w podejściu holistycznym. Przeanalizowano holistyczne ujęcie logistyki wojskowej jako podstawę rozwoju teorii logistyki wojskowej. Scharakteryzowano wywodzące się z holizmu podejście systemowe. teleologię, procesualizm oraz prakseologię. Stwierdzono, że logistyka wojskowa występuje najczęściej jako specjalność naukowa w naukach: o bezpieczeństwie, zarządzaniu i jakości oraz naukach inżynieryjno-technicznych. Określono, że o przedmiotem badań w logistyce są systemy logistyczne i realizowane w ich ramach procesy oraz, że nie dysponuje ona dostatecznie rozwiniętym aparatem poznawczym i metodologicznym. Przedstawiono relacje pomiędzy teorią systemów a logistyką wojskową oraz scharakteryzowano wojskowe systemy logistyczne oraz ich cechy i funkcjonowanie.
W wyniku przeprowadzonych badań sformułowano następujący wniosek: holizm i wywodzące się z niego podejście systemowe może stanowić podstawę rozwoju teorii i poznania w logistyce wojskowej.

Teachers play a pivotal role in the education systems of any nation. Their mental and psychological well-being is critical in achieving positive student educational outcomes. However, professional teacher burnout has been on the rise. Self-awareness is essential to helping individuals connect with their emotional state and how it affects their behavior and those they interact with. This study sought to assess the effect of self-awareness coaching on professional teacher burnout among teachers in public secondary schools in Kiambu County, Kenya. Weiner's theory of attribution and Goleman's mixed model of emotional Intelligence informed this study (Goleman, 1995).   Quasi experiment Solomon four design with a target population of 3469 teachers from 277 public secondary schools of all categories in the County was used. Krejci and Morgan's table was used to sample 346 teachers, while eight principals and 40 Heads of departments were purposefully selected for the study.  Maslach Burnout Inventory and an interview guide were used to collect data for professional teacher burnout. A training manual was used to coach self-awareness.  Validity was achieved through expert advice and piloting, while reliability was established through the split-half method.  Paired t-tests and ANOVA were used for data analysis to get the effect size of coaching.   The results indicated that self-awareness coaching had statistically significant positive effects on professional teacher burnout at t = 15.779 at df=78, >.001, The effect size (Cohen d = 0.958) was high; hence, emotional self-awareness coaching significantly reduced professional teacher burnout. The study recommended that the teacher employer (TSC) develop programs to equip teachers with self-awareness skills to curb professional burnout, thereby increasing their productivity
