Role of Long Stem Tibial Implant in Total Knee Arthroplasty (TKA)
Authors: V Sherlekar Vinay , K Sreedish
Published: October 2024

Total Knee Arthroplasty (TKA) is a common surgical intervention for patients with advanced osteoarthritis. However, cases involving severe bone defects, particularly in the medial tibial condyle, present unique challenges for successful implant fixation and long-term stability. This case report discusses a 65-year- old male with Kellgren and Lawrence Grade 4 osteoarthritis and a large medial tibial condyle defect. A customized approach using a long-stem tibial component and an autograft harvested from bone cuts was employed. Post-operatively, the patient demonstrated significant improvement in range of motion (ROM 0-120 degrees) by post-operative day 10 and early weight-bearing capabilities, indicating a successful outcome. The use of a long-stem tibial component provided additional stability, while the autograft helped fill the defect, restoring structural integrity. This case underscores the importance of individualized treatment strategies in complex TKA cases and highlights the need for further research on the long-term outcomes of using autografts and long-stem implants in patients with large bone defects.
Strategies Employed by Wakilisha Program in Communicating Alcohol Abuse Messages to the Youth in Vihiga Sub County, Kenya
Authors: Isiaho Sharon , Nyambuga Charles
Published: October 2024

Numerous studies emphasise the media's crucial role in spreading health information, encouraging healthy behaviours, and influencing public health outcomes. Radio remains the dominant medium for accessing information in Kenya, with around 74% of Kenyans aged 18 and above and approximately 21 million citizens, regularly consuming radio content. Despite the Wakilisha radio program running from 2016 and focusing on topics like drug and alcohol abuse, alcohol abuse remains a significant issue in Vihiga County, especially among the youths. This study therefore purposed to assess the strategies employed by the Wakilisha Program in communicating alcohol abuse messages to the youth in Vihiga Sub-County. This study adopted a cross-sectional mixed-method research design. The study population consisted of 22,047 youths, the head of programmes and one radio presenter. The researcher used Yamane (1967) formula to get a sample size of 393 listeners. The study used systematic random sampling to select radio listeners’ respondents from Vihiga subcounty and purposive sampling to select the two radio personnel. Questionnaires and interview schedules were used to collect data from Wakilisha programme listeners and two radio personnel. Quantitative data was analysed using descriptive statistics while qualitative data was analysed through textual analysis. The study found out that the programmes used the following strategies; audience- preferred language, the preferred programme format, and preferred timing and engagement of listeners in determining Wakilisha content.

City Oasis: Can Parks Be Havens for Biodiversity? A Look at Ecopark, Rajarhat
Authors: Basu Roy Arjan , Chatterjee Lina , Samanta Tarak , Sengupta Nivedita , Barve Vijay
Published: October 2024

Urban parks offer a vital refuge for biodiversity in large cities, providing a wealth of ecosystem services. Larger parks and reserves within these urban areas tend to boast higher species richness than smaller urban parks, as they function as protected areas that harbor both diverse plants and animals (Nielsen et al. 2014). This study also explored how faunal species utilize restored habitats within Ecopark at Rajarhat, a large urban park (Besra et al. 2022, Chatterjee et al. 2023, Rong et al. 2023). Data on species richness and resource use were collected over a period of two years (November 2020–October 2022) using line transects, point counts, light traps, and netting methods. Rarefaction analysis is a method used to measure the species richness and diversity and visual representations. Data representation using conventional images, including plots and charts, revealed significant differences in how species utilize resources and partition niches across various habitat types within the park. Based on their habitat preferences, species were observed in forestland, marshland, grassland, and water bodies within the park (Rong et al. 2023). There were 28 species of fungi across eight orders and 17 families (Samanta et al. 2022a). Additionally, 127 floral species belonging to 28 orders with 49 families (Biswas et al. 2023), and 395 species of fauna across 45 orders and 153 families (Chatterjee et al. 2022a, Roy et al. 2022a, Rong et al. 2023,Samanta et al. 2022b,Roy et al. 2022b) were included in this summary to highlight the biodiversity in this urban park. We mobilized these datasets through the Global Biodiversity Information Facility (Chatterjee et al. 2022b) to make sure the data is readily available for a wider set of data users and as open access. These findings suggest that habitat restoration efforts within Ecopark have significantly enriched faunal biodiversity. Because of rapid urbanization around the park, species have relocated from degraded habitats to the park's protected areas. The study's recommendations can guide conservation strategies to protect native species and contribute to a self-sustaining ecosystem within the park and surrounding areas.

Published: October 2024

Objectives: The research sought to examine the antibacterial properties of the conditioned media derived from dental pulp mesenchymal stem cells (DPSC) that were treated with curcumin.

Methods: An investigation of the physicochemical characteristics of curcumin nanoparticles was conducted utilizing scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and mapping techniques. The optimal dose of curcumin for treating DPSC cells was determined using the MTT test. The study investigated the antioxidant properties of curcumin on DPSC cells by measuring ROS. Two groups were isolated, one without treatment (control) and the other treated with curcumin. The antibacterial and antifungal properties of the supernatant culture medium of DPSC cells were then investigated.

Results: The present study results indicate that curcumin possesses suitable physicochemical properties, including morphology and purity. Additionally, it exhibits no toxicity at doses ranging from 0 to 1.25 (μg/ml) and displays antioxidant properties at the IC50 concentration. Furthermore, it increases DPSCs. The antimicrobial results demonstrate that CM-CUR, at various concentrations, reduces the viability of Streptococcus mutans (S. mutans) and inhibits the growth of Candida albicans (C. albicans) by 85%.

Conclusion: The research results indicate that the combination of CM-CUR is suitable for antibacterial and antifungal applications in dentistry to enhance human health.
Optimization of hybrid photovoltaic-thermal systems integrated into buildings: Impact of bi-fluid exchangers and filling gases on the thermal and electrical performances of solar cells
Authors: Toka Kokou Aménuvéla , Nougbléga Yawovi , Amou Komi Apélété
Published: October 2024

The low cooling efficiency of photovoltaic panels integrated into building façades restricts their electrical performance. The innovative approach of a dual-fluid photovoltaic-thermal system (BFPVT), incorporating bi-fluid cooling exchangers, appears to be a promising solution for jointly optimizing the electrical and thermal performance of PVT systems. However, despite the introduction of air heat shields to improve this performance, their limited efficiency makes them less competitive. We present a photovoltaic-thermal (PVT) system with a two-channel heat exchanger. The upper channel contains a stagnant fluid, which acts as a heat shield, while the lower, open channel ensures the continuous circulation or evacuation of heat transfer air. A copper metal plate separates the two channels. We examined the impact of various fluids employed as heat shields, including neon, argon, and xenon, in comparison to air, on the thermal and electrical performance of the collector. We employed numerical modeling of convective and conductive transfers to assess the average thermal efficiency of the BFPVT and the rise in PV temperature in the analyzed configuration. The equations were discretized using the implicit finite difference method and solved using the Thomas and Gauss-Seidel algorithms. The results demonstrated an 18% enhancement in thermal efficiency with the utilization of neon. In contrast, the employment of argon and xenon markedly reduced the mean temperature of photovoltaic cells by 4.82 ℃ and 4.87 ℃, respectively. This led to an increase in their electrical efficiency by 0.33% in comparison to air. Thus, argon is regarded as the optimal choice for optimizing electrical efficiency, taking into account both economic and environmental considerations.

The Transition of Waste Management According to the EU and Ukrainian Legislation
Authors: Leheza Yuliia
Published: October 2024

The purpose of the chapter research is to establish the content of the adaptation of the legislation of Ukraine on waste to the legislation of the countries of the European Union on the basis of the analysis of the system of normative legal acts of Ukraine, acts of international legal regulation and acts of the EU. Achieving the goal and objectives of the chapter research occurs through the use of general scientific and special legal methods of cognition. A systematic comprehensive approach to the study of the object and subject of research requires the use of methods for determining the social normative content and legal form. It has been established that the current regulatory legislation of Ukraine determines the vector of its development for the implementation of EU legislative standards in general, and in particular for the regulation of waste management. However, it was determined that the practical implementation of the principles of a circular economy, where waste plays the role of property and requires responsible handling in Ukraine, is characterized extremely negatively, which is associated with both objective reasons (lack of investment in creating an infrastructure for proper waste management and recycling) and subjective reasons (low level of legal consciousness of the population, which requires a responsible attitude to solving the problem of separate collection and sorting of waste, rational consumption), etc. The article emphasizes the lack of unity of approaches to establishing the content of the category ‘waste’, which is enshrined both at the legislative level (in the Laws of Ukraine ‘On Waste’, ‘On Waste Management’, ‘On Alternative Types of Fuels’) and at the regulatory level (in the State Waste Classifier). The author also identifies the ambiguity of practical approaches to the practice of regulating waste circulation.
Gender, race, and life writing in the ethnography of Ruth Landes in Bahia
Authors: Cole Sally
Published: October 2024

American anthropologist Ruth Landes (1908-1991) conducted ethnographic fieldwork in candomblé centers, terreiros, in Salvador, Bahia, in 1938-1939. In her book City of Women (1947) and journal articles she recorded her observations on matrifocality and gender variance and portrayed Afro-Brazilian culture as dynamic and innovative. This article examines how Landes’s theory of culture, methods of fieldwork, and personal writing style went against the grain of the approaches taken by leading scholars at the time who treated Afro-Brazilian culture in terms of race-based psychological characteristics and “African survivals” and harshly critiqued her work.

San la Muerte : un métissage religieux insistant
Authors: Burnot Maureen
Published: October 2024

Cet article propose de retracer le processus de configuration du culte à San la Muerte en Argentine à partir d’archives, de sources historiques et de données ethnographiques. Nous explorons dans un premier temps les données qui permettent de saisir comment se sont combinés progressivement les éléments catholiques et indigènes au moment de la genèse de la dévotion, avant d’interroger la transformation de l’amulette – objet de pouvoir – en un saint populaire au cours du xxe siècle. À partir d’une approche simultanément anthropologique et historique, nous montrons que San la Muerte condense des éléments des traditions guarani et chrétienne, et constitue une expression métisse et autonome de l’identité argentine.

À partir du cas de la danse des búzios des Pankararu, groupe indigène de l’État du Pernambouc au Brésil, il explore particulièrement deux dimensions entrelacées de la récupération culturelle : l’une est collective et implique l’adoption d’une pratique, sa transformation puis son exhibition ; l’autre est individuelle, à travers l’ascension politique d’un leader aujourd’hui reconnu nationalement.
New records for hoverflies (Diptera: Syrphidae) in Alberta, Canada
Authors: Pizante Rachel , Frost Carol M. , Acorn John H.
Published: October 2024

Little is known about the distribution and natural history of hoverflies (Diptera: Syrphidae) in western Canada. Filling in knowledge gaps and tracking this potentially changing fauna are important because hoverflies are likely important pollinators and are natural pest control agents for crops. Hoverflies were collected using Malaise traps placed near fields seeded to canola in central Alberta from May to August 2021. Platycheirus varipes Curran represents a new species record for Alberta. Two species of conservation concern and two species with extremely limited collection records were also collected. A species that was previously found only in mountainous regions and another three species whose Albertan records consisted only of iNaturalist records were found.
Ambient micro-vibration measurements in geotechnical engineering: a practical approach to the HVSR method
Authors: Perret D. , Dietiker B. , Gravel J. -P. , Fournier T. , Pugin A. J. -M.
Published: October 2024

Depuis les dix dernières années, la communauté géotechnique s’intéresse de plus en plus à une technique géophysique basée sur l'analyse du bruit ambiant enregistré à l’aide d’un sismomètre à trois composantes à la surface du sol. Le but de cette technique est de calculer le rapport des spectres d'amplitude de Fourier des composantes horizontale et verticale de l'enregistrement, communément appelé HVSR. (Horizontal to Vertical Spectral Ratio). Lorsque le contraste de vitesse de l'onde de cisaillement entre le substratum rocheux, ou un till dense, et le sol au-dessus est suffisamment élevé, la courbe HVSR montre généralement un pic net à une fréquence correspondant à la fréquence fondamentale du site. En raison de sa mise en œuvre simple sur le terrain et de son faible coût, cette technique est bien adaptée à la cartographie de la fréquence fondamentale pour le microzonage sismique et à l'évaluation des effets potentiels de double résonance entre le sous-sol et les structures construites au-dessus. Cette technique peut également être utilisée pour estimer la profondeur du substratum rocheux et pour extrapoler des profils de vitesse des ondes de cisaillement jusqu'à un substratum rocheux profond dans des analyses de réponse dynamique spécifiques au site. En outre, la connaissance de la fréquence fondamentale peut permettre d’identifier des erreurs dans le profil de vitesses des ondes de cisaillement. Quelques exemples pris dans l’est du Canada illustrant ces différentes applications sont présentés et discutés de manière critique dans l'article, en mettant l'accent sur les limites de la technique.
Beliefs and adoption of AI in content marketing: Insights from South African marketing agencies
Authors: Du Plessis Charmaine , Swart Christelle
Published: October 2024

Background: Notwithstanding a large body of academic literature on artificial intelligence (AI) in computer science and other technical fields dating back decades, research is needed on how AI is applied in the context of marketing. Marketers have used AI for many years, but generative AI has only recently come to the forefront. The study focussed on understanding the beliefs and adoption of AI in content marketing practices in South Africa.Objectives: By combining various perspectives in the marketing industry, a taxonomy is proposed that categorises current AI practices in content marketing.Method: An exploratory web-based survey was adopted. It was important to measure the scope and extent of beliefs, acceptance, and adoption of AI in content marketing, and to gain insights to categorise current AI practices in content marketing. Data analyses of the closed-ended and open-ended questions were conducted using JMP®, 17.2 (SAS Institute Inc., Cary, NC 2023) and through inductive thematic analysis, respectively.Results: The findings reveal that South African marketing agencies currently adopt AI for content strategy optimisation, content creation enhancement, insight integration and personalisation, automation and process enhancement.Conclusion: While South African marketing agencies acknowledge the value of AI in improving content marketing, they believe that the human element is still necessary, and that content marketing practice cannot depend entirely on AI.Contribution: The proposed taxonomy lays the foundation for future research about AI in content marketing with a larger sample.
Haefliger’s differentiable cohomology
Authors: Accornero Luca , Crainic Marius
Published: October 2024

We review Haefliger’s differentiable cohomology for the pseudogroup of diffeomorphisms of

\mathbb{R}^{q}

; see “Haefliger (1976)”. We unravel the structure that governs such cohomologies, which, remarkably, is related to the so called Cartan distribution underlying the geometric study of PDEs. Hence, we extend Haefliger’s differentiable cohomology to the general framework of flat Cartan groupoids, investigate its infinitesimal counterpart, and relate the two by a van Est-like map. Finally, we define a characteristic map for geometric structures on manifolds associated with flat Cartan groupoids. The outcome generalizes the existing approaches to characteristic classes for foliations “Bernšteĭn and Rosenfel’d (1972)”, “Bott and Haefliger (1972)”, “Bernšteĭn and Rosenfel’d (1973)”, and “Haefliger (1976)”. The motivation for this work is two-fold. On the one hand, it is motivated by the recent approach to geometric structures via multiplicative (Cartan) distributions; see “Salazar (2013)”, “Yudilevich (2016)”, and “Cattafi (2020)”; from that perspective, we are constructing characteristic classes for such structures. On the other hand, it is motivated by our (ongoing) attempt to turn classical symmetries (pseudogroups) into non-commutative, Hopf-algebraic, ones; such attempt is inspired by existing work in non-commutative geometry; see “Connes and Moscovici (2001)”, “Moscovici and Rangipour (2009)”, and “Moscovici and Rangipour (2011)”. It also aims at a unified approach which allows for non-transitive pseudogroups.
On possible symmetry groups of 27-vertex triangulations of manifolds like the octonionic projective plane
Authors: Gaifullin Alexander Aleksandrovich
Published: October 2024

In 1987 Brehm and Kühnel showed that any triangulation of a $d$-manifold (without boundary) that is not homeomorphic to a sphere has at least $3d/2+3$ vertices. Moreover, triangulations with exactly $3d/2+3$ vertices can exist only for ‘manifolds like projective planes’, which can have dimension $2$, $4$, $8$ or $16$ only. There is a $6$-vertex triangulation of the real projective plane $\mathbb{RP}^2$, a $9$-vertex triangulation of the complex projective plane $\mathbb{CP}^2$ and $15$-vertex triangulations of the quaternionic projective plane $\mathbb{HP}^2$. Recently the author constructed first examples of $27$-vertex triangulations of manifolds like the octonionic projective plane $\mathbb{OP}^2$. The four most symmetric of them have the symmetry group $\mathrm{C}_3^3\rtimes \mathrm{C}_{13}$ of order $351$. These triangulations were constructed using specially designed software after the symmetry group had been guessed. However, it remained unclear why exactly this group is realized as a symmetry group and whether $27$-vertex triangulations of manifolds like $\mathbb{OP}^2$ with other (possibly larger) symmetry groups exist. In this paper we find strong restrictions on the symmetry groups of such $27$-vertex triangulations. Namely, we present a list of $26$ subgroups of $\mathrm{S}_{27}$ containing all possible symmetry groups of $27$-vertex triangulations of manifolds like the octonionic projective plane. (We do not know whether all these subgroups can be realized as symmetry groups.) The group $\mathrm{C}_3^3\rtimes \mathrm{C}_{13}$ is the largest group in this list, and the orders of all other groups do not exceed $52$. A key role in our approach is played by the use of results of Smith and Bredon on the topology of fixed-point sets of finite transformation groups.

BACKGROUND

Inflammatory bowel disease (IBD), with its rising prevalence rates is associated with an increased risk of cardiovascular and thromboembolic events. Antiplatelets and/or anticoagulants agents are often prescribed but the literature on the impact of long-term anticoagulation and/or antiplatelet use among patients hospitalized with IBD is scarce. The aim of this study is to assess the outcomes of patients hospitalized with IBD on antiplatelet and/or anticoagulant agents.

AIM

To investigate the effects of long-term use of antiplatelets/anticoagulants on clinical outcomes in patients hospitalized with IBD.

METHODS

We conducted a retrospective cohort study using the Nationwide Inpatient Sample database, including all adult IBD patients hospitalized in the United States from 2016 to 2019. Patient cohorts were stratified based on antiplatelet/anticoagulant therapy status. Multivariate regression analysis was done to assess outcomes, adjusting for potential confounders. The primary outcome was mortality, whereas length of stay (LOS), total parenteral nutrition, acute kidney injury, sepsis, shock, gastrointestinal bleeding, need for colonoscopy/sigmoidoscopy, abdominal surgery and total hospitalization charges were secondary outcomes.

RESULTS

Among 374744 hospitalized IBD patients, antiplatelet or anticoagulant therapy alone was associated with significantly lower in-hospital mortality and reduced healthcare utilization, including shorter LOS and decreased hospitalization costs. Combined therapy was associated with a protective effect on mortality, but did not reach statistical significance. Notably, therapy did not exacerbate disease severity or complications, although higher odds of gastrointestinal bleeding were observed.

CONCLUSION

Our study highlights the potential benefits of long-term anticoagulation/antiplatelet therapy in hospitalized IBD patients, with improved mortality outcomes and healthcare utilization. While concerns regarding gastrointestinal bleeding exist, the overall safety profile suggests a role for these agents in mitigating thromboembolic risks without exacerbating disease severity. Further research is needed to look at optimal treatment strategies and addressing limitations to guide clinical decision-making in this population.
Kotter’s Eight-Step Change Process Model and Students’ Attitudes towards Fees Payment Policies in Public Universities in Uganda
Authors: Mukwenda Hilary
Published: October 2024

This study aimed at exploring the attitudes students in three public universities in Uganda hold towards tuition fees policies. It also investigated the relationship between Kotter’s Eight-Step Change Process Model and these attitudes. Data was collected from 360 students drawn from Busitema University, Kyambogo University, and Makerere University. These were selected using stratified and cluster sampling. Data was collected using questionnaires and subjected to regression analysis. The findings show that many students have a low opinion of, and are opposed to, their universities’ tuition policies. However, most of the steps in Kotter’s Model were significantly (positively) related to the students’ attitudes towards the policies. It was concluded that the model can guide efforts to enhance the effectiveness of tuition fees policies in the universities. Hence, the universities are urged to orientate enforcement of their fees policies towards the steps in the model.
Legal Identification Documents
Authors: Abasabyona Milcah
Published: October 2024

This paper explores how a new hierarchy of legal Identification Documents (IDs) in Uganda, topped by the National Identification Document (NID), interchangeably referred to as the national identity card, Endanga-Muntu, or a national ID in this paper, has diminished the value of a wider range of forms of recognition. It also examines how this new hierarchy has generated structural discrimination and escalated selective inequalities among differentiated citizens, leading to disenfranchisement. Using a case of the ghetto youths in Kampala slums of Kamwokya and Bwaise, this paper argues that  the range of legal IDs within Uganda’s overall national registration ecosystem over time have included multiple and overlapping identification mechanisms, such as birth registration cards, local council village cards, residence IDs, baptism cards, voter’s card, tax payment slip, driver’s license, citizens’ passport, written A4 paper letters, marriage certificates, and others, acceptable in various formal and informal spaces until the recent introduction of a NID which manifests both as a threat and an opportunity to the ghetto youths.

Published: October 2024

INTRODUCTION: Optimal reporting of incidents occurring in healthcare is important for improving patients’, visitors’ and workers’ safety. There are unsatisfactory rates of incident reporting worldwide, with some institutional and provider-related barriers. The aim of this study was to assess factors affecting incident reporting among nurses working at the largest teaching hospital in Rwanda. 
METHODS: This is a cross-sectional descriptive study conducted among 166 nurses working in main 5 departments of the University Teaching Hospital of Kigali (CHUK) in 2019, using self-administered questionnaire. Data were compiled and analyzed through SPSS 27.0; statistical tests run through GraphPad Prism 9.5. 
RESULTS: Most respondents (58.3%) were middle-aged, female (83.1%), advanced diploma holders (72.3%), and with a 3–4-year working experience. Institutional-related barriers to incident reporting were predominated by the complexity of work (64.6%), shortage of staff (55.8%), and inadequacy of incident reporting system (43.3%). Fear of being punished (77.5%) and lack of knowledge on what should be reported (67.2%) were the most frequent professional-associated barriers. There was statistically significant association of lower level of education versus complexity of work (P=0.0474, OR=2.056, 95% CI=1.017 – 4.148), younger age versus lack of knowledge on what to report (P=0.0390), lower level of education versus the fear of being punished (P=0.0030, OR=3.417, 95% CI=1.566 – 7.493), lower level of education versus lack of knowledge on what to report (P<0.0001, OR=4.271, 95% CI=2.066 – 8.608), and shorter professional’s working experience versus lack of knowledge on what to report (P=0.016). 
CONCLUSION: Identified barriers should be addressed according to their levels, to optimize incident reporting and thus safety in healthcare facility. User-friendly incident reporting system should be designed, and efficient human resource management ensured. Moreover, principles of incident reporting should be incorporated in the induction, orientation and continuing professional development programs of healthcare staff.

ABSTRAK 
Ada tiga faktor yang mempengaruhi keberhasilan usaha peternakan: genetika, pakan, dan manajemen. Sekitar enam puluh hingga tujuh puluh persen biaya produksi untuk pengadaan pakan. Umumnya pakan babi di Nusa Tenggara Timur terdiri dari limbah pertanian dan sisa makanan rumah tangga sehingga menyebabkan rendahnya produktivitas babi. Pengetahuan peternak babi tentang cara pembuatan pakan babi yang benar dan sesuai kebutuhan pakan babi masih rendah, oleh karena itu dilakukan kegiatan pengabdian kepada masyarakat yang bertujuan untuk meningkatkan pengetahuan kelompok peternak Tiberias ImanTap Desa Bipolo Kecamatan Sulamu Kabupaten Kupang tentang pembuatan dan pemberian pakan ternak babi. Metode pelaksanaan kegiatannya melalui penyuluhan dan demonstrasi. Hasil dari kegiatan ini menunjukkan adanya peningkatan sebesar 66,7% pengetahuan kelompok mitra tentang pembuatan pakan babi sehingga dapat menjadi salah satu faktor untuk meningkatkan produktivitas ternak yang dipelihara kelompok mitra

Dramaturgy and philosophy in anti-realist theatre
Authors: ULUSOY Ali Ömür , SANİOĞLU Nesli Meriç
Published: October 2024

Anti-realist theatre was born in the last quarter of the XIXth century as a counteraction to the conception of the realist theatre with the internal contradiction of modernism itself and it had significant effects on today's theatrical way of thinking, from writing to direction, from stage design to the use of light. In particular of epistemology and axiology, this study ,  aims to clarify the impact of the symbolism, aestheticism and new romanticism, which emerged from the anti-realist theatre on text writing, direction, stage design and lighting within the framework of the period between the last quarter of the XIXth century and the first quarter of the XXth century.         Under all this perspective, the links/parallels of the anti-realist theatre which exhibits an oppositional stance contrary to the realist conception of the age,  with the philosophers, who are also prominent with their oppositional stance, have been evaluated on the axis of dramaturgy.

El artículo explora la creciente brecha digital en zonas rurales, una problemática que se intensificó con la pandemia de COVID-19, afectando gravemente a la educación. Las diferencias en el acceso a la tecnología y la infraestructura de banda ancha han limitado las oportunidades de aprendizaje para los estudiantes rurales, que se enfrentan a barreras tecnológicas y a la falta de recursos adecuados para participar en entornos de aprendizaje en línea. Este artículo revisa las principales soluciones tecnológicas propuestas para reducir esta brecha, incluyendo la expansión de la conectividad a través de la banda ancha y el uso de tecnologías móviles para llevar la educación a áreas remotas. También, se analizan iniciativas como las bibliotecas rurales que, mediante el acceso a recursos tecnológicos, permiten a los estudiantes rurales acceder a herramientas digitales esenciales. La alfabetización digital es otro aspecto crucial abordado, subrayando la importancia de capacitar a las comunidades en el uso de tecnologías para fomentar la inclusión educativa. Los docentes también desempeñan un papel fundamental en la integración tecnológica, ya que actúan como mediadores que facilitan la transición hacia una educación más equitativa. Además, se examinan políticas públicas y proyectos comunitarios que promueven la equidad digital, destacando cómo la cooperación entre gobiernos, organizaciones y comunidades puede contribuir a cerrar la brecha digital. Finalmente, se concluye que la implementación efectiva de soluciones tecnológicas no solo mejorará el acceso a la educación, sino que también proporcionará oportunidades de desarrollo sostenibles para las zonas rurales a largo plazo, garantizando una mayor equidad educativa.
The Effect of Reward on the Improvement of Self-Confidence in Children Aged 5-6 Years at TK Negeri Pembina Pemenang in the 2023/2024 Academic Year

Self-confidence is a positive attitude that individuals must possess to meet various needs in their environment or situations, which allows them to believe in their own abilities for the purpose of achieving personal happiness. This study aims to examine the effect of rewards on the improvement of self-confidence in children aged 5-6 years at TK Negeri Pembina Pemenang during the 2023/2024 academic year. This research employs a quantitative quasi-experimental design with a Nonequivalent Control Group Design. The sample in this study was selected through non-probability sampling, involving 24 children aged 5-6 years at TK Negeri Pembina Pemenang, consisting of 14 boys and 10 girls. The analysis method used is the Independent Sample T-test. The results of the data analysis show that the t-value is greater than the critical t-value (19.707 > 1.717), indicating that the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted. Thus, the hypothesis can be considered valid. Based on these findings, it is concluded that giving rewards positively affects the improvement of children's self-confidence, as evidenced by the higher self-confidence scores in the experimental group after receiving the reward intervention compared to before. It is recommended that educators acknowledge and reward children, particularly those with lower self-confidence, to help them feel more comfortable both at school and outside of school.

This study aims to explore the influence of organizational culture and change management on organizational performance in local government agencies in West Kalimantan. A strong and innovative organizational culture has been proven to play a significant role in improving efficiency, productivity, and the quality of public services. On the other hand, change management does not show a significant impact on performance, due to various obstacles such as resistance to change and a lack of integration of change strategies within the organization. This research used a survey method with a quantitative approach, involving 181 respondents from several districts/cities in West Kalimantan. The data were analyzed using Structural Equation Modeling (SEM). The results of the study indicate that organizational culture has a positive and significant influence on organizational performance, while change management does not have a significant impact. These findings provide important implications for policymakers in strengthening organizational culture and improving the effectiveness of change management strategies to achieve optimal performance. The study also suggests that support from strong leadership and employee engagement are key elements for the success of organizational change. Therefore, focusing on strengthening organizational culture is crucial to achieving better performance in the public sector.
A BYD Magyarországon
Authors: Vinczellér Gergely
Published: October 2024

A BYD kínai autómárka bár már 1995 óta létezik, azonban hazánkban csak 2023 óta vált szélesebb körben ismertté. A BYD márka ismertségének kétségtelenül jót tett, hogy Magyarországon tavaly több olyan autószalon is megnyílt, amely elsődlegesen a BYD márka értékesítésére fókuszál, de a márkanév ismertebbé válásában az elektromos autózás növekvő népszerűségének is bizonyosan van szerepe. Az előbbiek dacára azonban a BYD márka kérdéskörét mégis egy harmadik megközelítésben vizsgáljuk meg, és elsődlegesen arra a kérdésre kívánunk választ találni, hogy az említett globális kínai autómárka a közép-európai régióban miért pont hazánkban jelent meg először, és milyen okok játszottak abban közre a vállalat üzleti és piaci stratégiája szempontjából, hogy az európai terjeszkedésének kiindulási pontjául éppen pont Magyarországra esett végül a választása, megvalósítva így hazánkban a rendszerváltás óta, a legnagyobb mértékű külföldi beruházást.
A quebra do paradigma de Yang-Mills: o modelo de Jackiw-Pi
Authors:   , Pereira Emílio Drumond
Published: October 2024

As teorias de gauge são formuladas para descrever campos de matéria que apresentam uma simetria local, conhecida como simetria de gauge. O grande impacto dessas teorias é obtido ao utilizar algum método para quantizá-las. Partindo de grupos de simetria especı́ﬁcos, como, por exemplo, o grupo U (1), o SU (2) e o SU (3), é possı́vel obter o modelo padrão da fı́sica de partı́culas, isto é, uma teoria que descreve três interações fundamentais: interação eletromagnética, fraca e forte. Tais teorias também podem ser estudadas em diferentes dimensões espaço-temporais e ainda assim possuir interesse além do teórico. Em particular, quando estudadas em três dimensões espaço-temporais, forneceram modelos que contribuı́ram para a compreensão de fenômenos como o efeito hall quântico e sobre sistemas como o grafeno e isolantes topológicos. Ainda nessa dimensionalidade, em 1997, os fı́sicos Roman Jackiw e So-Young Pi propuseram uma teoria de gauge massiva que, ao contrário da teoria de Chern-Simons, preserva a simetria de paridade e, além disso, quebra o paradigma de Yang-Mills (generalizações não-abelianas de modelos abelianos). Portanto, tendo em vista a peculiaridade do modelo de Jackiw-Pi, o foco principal do presente trabalho é estudá-lo e será composto da seguinte forma: uma introdução às teorias de gauge, discutindo sucintamente a eletrodinâmica quântica e as teorias de Yang-Mills; A origem da simetria BRS e sua relação com a unitariedade da matriz S; os aspectos da renormalização algébrica, que será o procedimento utilizado para a análise da quantização do modelo; o estudo dos aspectos clássicos e quânticos do modelo de Jackiw-Pi. Por ﬁm, é feita a conclusão sobre a possibilidade de quantização e apresentadas as perspectivas futuras. Palavras-chave: Renormalização algébrica. Simetria BRS. Jackiw-Pi.
