Análisis Comparativo del Impacto Económico de Emprendimientos Caseros de Repostería en Pastelerías Formales de Chetumal
Authors: Aguilar Martínez Jonathan Alexander
Published: November 2024

El objetivo de este estudio fue analizar el impacto económico de los emprendimientos caseros de repostería en las pastelerías formales de Chetumal, Quintana Roo. Se empleó un enfoque metodológico mixto, combinando encuestas cuantitativas aplicadas a propietarios de pastelerías formales e informales, junto con entrevistas cualitativas para explorar sus percepciones sobre la competencia y las estrategias de adaptación. Los principales hallazgos indican que los emprendimientos caseros tienen una ventaja competitiva basada en la personalización de productos y costos operativos más bajos, lo que les permite ofrecer precios accesibles. Sin embargo, las pastelerías formales se benefician de mayor credibilidad y acceso a recursos financieros, lo que les permite competir en términos de calidad y seguridad. A pesar de la competencia, ambos tipos de negocios pueden coexistir mediante la diferenciación de productos y estrategias de fidelización del cliente. El estudio concluye que la formalización de los emprendimientos caseros, de manera gradual, podría fomentar su crecimiento sin perder flexibilidad, mientras que las pastelerías formales necesitan innovar y diferenciarse para mantener su competitividad en un mercado cambiante. Se sugiere una mayor investigación sobre la sostenibilidad de los emprendimientos caseros y el impacto de la digitalización en el sector.

Published: November 2024

The use of technology and information is crucial for keeping up with emerging business trends as the Industrial Revolution 4.0 expands and heads towards 5.0. Particularly crucial is the use of enterprise resource planning (ERP) for enterprise management. ERP systems aid companies in managing projects and resource utilization while reducing time and effort expenditure. The procedures are carried out mechanically rather than by hand. Errors are prevented by the system's simultaneous proper and efficient operation. ERP data allows businesses to make important decisions. In the fashion sector, the business and product standards are very dissimilar. It is essential to have an ERP system that can manage purchases as well as handle inventory items, pricing, corporate structures, and campaign management. ERP features include a system with a huge number of data, the use of a top-down strategy that enables production chain management to be attentive, and the realization of complete ERP system management. The ERP system has improved control over the manufacturing chains in many businesses. This essay examines the use of ERP in the apparel sector and examines some of the possible advantages. The information used in this study was compiled from several academic sources as well as other sources like reports and other materials. At the conclusion of the paper, the conclusions and suggestions were discussed. Manufacturing organizations may profit from ERP systems in today's hyperconnected, data-driven economy if staff receive proper training and reliable data, as the value of ERP systems directly depends on data quality.

Use of Anabolic Androgenic Steroids: Performance Enhancement or Health Hazard?
Authors: Chhikara Ankita , Banik Amlan
Published: November 2024

Anabolic androgenic steroids (AAS) are synthetic medications used in fitness, medicine, and sports that replicate the effects of androgens in the body, such as testosterone. They are used to treat AIDS, some malignancies, and low testosterone. It is critical for society and medicine to comprehend the advantages and disadvantages of AAS. Steroids enhance androgen receptors, which inadvertently result in stronger muscles and higher workout intensities. Additionally, they activate the brain via the growth hormone-insulin-like growth factor-1 axis and a variety of neurotransmitters. Cycles of "cycling," "pyramidation," or "plateauing," in which the body progressively reduces the cycle without abruptly terminating it, is common pattern of steroid misuse. Additionally, "plateauing" with AAS is done to avoid resistance. The majority of consumers of AAS are bodybuilders and elite athletes, but the drug's widespread use among men has raised questions about possible health risks and self-prescription. AAS consumption should be known to medical practitioners for a number of reasons, such as self-prescription and suggestions from non- medical personnel.

Prospects of Implementing Inclusive Education in TVET Colleges in OR Tambo Inland District, South Africa
Authors: Nomtshongwana Thanduxolo Albert , Buka Andrea Mqondiso
Published: November 2024

Inclusive education in South Africa was one of the first steps taken to fight for equality and human rights after apartheid. With inclusive education, schools became less separated and more integrated, to make sure all kids, including those with disabilities, have the same opportunities to learn. This paper explored the prospects of implementing inclusive education within Technical and Vocational Education and Training (TVET) colleges in the OR Tambo Inland District of South Africa. This paper used a qualitative approach, where interviews were used to collect data from five managers of TVET colleges. The field data found that a few problems stopped inclusive education from being implemented in the five TVET colleges. The lack of infrastructure was the main challenge for implementing inclusive education in the TVET colleges. It is recommended that investments should be made in both the physical infrastructure and the human infrastructure to ensure that people with disabilities have access to quality education and training. This should include providing access to assistive technology and other forms of support and resources to ensure people with a disability have the necessary skills and knowledge to pursue their chosen career paths. Finally, it is important to create an inclusive environment that supports people with disabilities. This study adds to the growing literature on enforcing inclusive education particularly those with disabilities, in vocational education settings.

Teaching With Technology: A Reflection on the Experience of Teaching With Computer Simulations
Authors: Tsoka Maxwell
Published: November 2024

This paper describes the lived experience of one physical science teacher teaching with computer simulations in a rural school. The teacher’s goal was to improve the teaching and learning of the physical sciences, which has been identified as a challenge. The study adopted an auto-hermeneutical approach, a method of self-reflection and interpretation, which was deemed appropriate for this study, as it allowed the teachers to critically reflect on their own experiences and interpret the impact of computer simulations on their teaching. The study was also framed by constructivism. Data was gathered from the teacher’s reflective journals and focus group discussions with learners. A qualitative data analysis using the Colaizzi method was employed. The outcome revealed that the use of computer simulations is an odyssey, where actions were initiated that pacified teacher-dominated practices. One important transformation to learning was that computer simulations created a learning environment where learners did not passively accept but actively engaged with and believed the scientific ideas being taught. The ultimate goal of the transformation is the meaningful engagement of learners with content in a way that captures the zeitgeist of the 21st century.

Authors: Pietersen Doniwen , Ngobeni Stanley Taren , Myende Thembeka
Published: November 2024

The aim of this study was to highlight the plight of women (African/Black) and how they are being excluded from theological and educational spaces, practices and leadership positions in African schools and universities due to patriarchal structures, cultural insensitivity, and colonial and post-colonial pasts. This research used an interpretive paradigm and a qualitative approach to explore the need for a decolonial feminist perspective to promote equity and opportunities for women in academia. The findings revealed the need for theological and educational spaces to reset so that these spaces could be challenged in terms of the shape of language, power structures and leadership opportunities.The researcher recommended decolonisation in higher education, focusing on women’s experiences and incorporating women-specific embodiment in educational and theological spaces, to offer a more comprehensive perspective on complex dialogue including changing policy formation. The study provides a decolonial feminist approach which could guide women in religious and educational settings, enabling them to become leaders and change the trajectory of these fields, promoting fairness, diversity, and inclusion.

Global Magni4icence, or: 4G Networks
Authors:   Stony Brook University, USA, Nekrasov Nikita , Piazzalunga Nicolo ,   Rutgers University, USA
Published: November 2024

The global magnificent four theory is the homological version of a maximally supersymmetric $(8+1)$-dimensional gauge theory on a Calabi-Yau fourfold fibered over a circle. In the case of a toric fourfold we conjecture the formula for its twisted Witten index. String-theoretically we count the BPS states of a system of $D0$-$D2$-$D4$-$D6$-$D8$-branes on the Calabi-Yau fourfold in the presence of a large Neveu-Schwarz $B$-field. Mathematically, we develop the equivariant $K$-theoretic DT4 theory, by constructing the four-valent vertex with generic plane partition asymptotics. Physically, the vertex is a supersymmetric localization of a non-commutative gauge theory in $8+1$ dimensions.

Hamiltonian paths passing through matchings in hypercubes with faulty edges
Authors: Zhao Shenyang , Wang Fan
Published: November 2024

Chen considered the existence of a Hamiltonian cycle containing a matching and avoiding some edges in an $ n $-cube $ Q_n $. In this paper, we considered the existence of a Hamiltonian path and obtained the following result. For $ n\geq4 $, let $ M $ be a matching of $ Q_n $, and let $ F $ be a set of edges in $ Q_n-M $ with $ |M\cup F|\leq2n-6 $. Let $ x $ and $ y $ be two vertices of $ Q_n $ with different parities satisfying $ xy\notin M $. If all vertices in $ Q_n-F $ have a degree of at least $ 2 $, then there exists a Hamiltonian path joining $ x $ and $ y $ passing through $ M $ in $ Q_n-F $, with the exception of two cases: (1) there exist two neighbors $ v $ and $ t $ of $ x $ (or $ y $) satisfying $ d_{Q_n-F}(v) = 2 $ and $ xt\in M $ (or $ yt\in M $); (2) there exists a path $ xvuy $ of length 3 satisfying $ d_{Q_n-F}(v) = 2 $ and $ uy\in M $ or $ d_{Q_n-F}(u) = 2 $ and $ xv\in M $.

The large language model (LLM) ChatGPT can answer open-ended and complex questions, but its accuracy in providing reliable medical information requires a careful assessment. As part of the AICHECK (Artificial Intelligence for CME Health E-learning Contents and Knowledge) Study, aimed at evaluating the potential of ChatGPT in continuous medical education (CME), we compared ChatGPT-generated educational contents to the recommendations of the National Institute for Health and Care Excellence (NICE) guidelines on acne vulgaris. ChatGPT version 4 was exposed to a 23-item questionnaire developed by an experienced dermatologist. A panel of five dermatologists rated the answers positively in terms of “quality” (87.8%), “readability” (94.8%), “accuracy” (75.7%), “thoroughness” (85.2%), and “consistency” with guidelines (76.8%). The references provided by ChatGPT obtained positive ratings for “pertinence” (94.6%), “relevance” (91.2%), and “update” (62.3%). The internal reproducibility was adequate both for answers (93.5%) and references (67.4%). Answers related to issues of uncertainty and/or controversy in the scientific community scored the lowest. This study underscores the need to develop rigorous evaluation criteria for AI-generated medical content and for expert oversight to ensure accuracy and guideline adherence.

Published: November 2024

This study assessed the effects of vitamin D on blood pressure in individuals diagnosed with diabetes mellitus. Convenience sampling and a cross-sectional, analytical, quantitative approach were used. Blood samples were collected and analysed by a designated laboratory officer to measure vitamin D levels. Twenty-eight (70%) women, 18 (45%) housewives with a median age of 52 (36-60), median systole of 143.5 (102–180), and median diastole of 80 years (range, 59–110 years). Thirty-five (87.5%) had fasting blood glucose over 140 mg/dl, and 33 (82.5%) postprandial more than 100 mg/dl. The predictive validity test showed that a systole cut-off score of 160–179 yielded sensitivity, specificity, LR+, and LR– (81%, 67%, 2.4, and 0.3). Systole had a LR+ of 2.4 and was a moderate diagnostic test. Diastole cut-off score of 90–99 produced sensitivity, specificity, LR+, and LR– (84%, 67%, 2.5, and 0.2). The ROC for systole was AUC 0.65 (95% CI: 0.49–0.80) and diastole had AUC 0.67 (95% CI: 0.50–0.81). Patients with diabetes and hypertension were found to have vitamin D levels <30 ng/mL.
Evaluating the Efficacy of Irisin Injection in Mimicking the Molecular Responses Induced by Endurance Exercise in Mouse Liver Tissue
Authors: Shahabi Shirin , Esfarjani Fahimeh , Zamani Saeed , Rarani Fahimeh Zamani , Rashidi Bahman
Published: November 2024

Background:

Physical activity has been found to improve liver health by reducing oxidative stress (OS), possibly through the protein irisin. Heat shock proteins (HSPs) and microRNAs (miRNAs) help regulate the body’s response to stress and maintain cellular health. This study aimed to investigate the expression of the HSP70 gene and protein, miR-223a, and serum irisin levels in the liver after 8 weeks of endurance exercise or irisin injection.

Methods:

Twenty-one mice were randomly assigned to a control group, an endurance training group, and an irisin injection group. The expression of the HSP70 gene and miR-223a was analyzed using real-time polymerase chain reaction (PCR), while HSP70 protein levels were measured using immunohistochemistry (IHC) and Western blot analysis. The concentration of irisin in the mouse serum was evaluated using the enzyme-linked immunosorbent assay (ELISA) method.

Results:

The endurance training and irisin injection groups exhibited a significant increase in the HSP70 gene (405.30% and 816.03%, respectively) and protein expression (173.89% in IHC, 36.76% in Western blot for endurance training; 206.73% in IHC, 59.80% in Western blot for irisin injection) as well as elevated serum irisin levels (49.75% for endurance training and 60.65% for irisin injection) compared with the control group. In contrast, miR-223a expression decreased in both the endurance training (21.37%) and irisin injection (52.80%) groups (P < 0.05 in all cases). Mice in the irisin injection group demonstrated higher levels of the HSP70 gene (81.28%) and protein expression (11.99% in IHC and 16.84% in Western blot) and lower miR-223a levels (39.97%) than those in the endurance training group (P < 0.05).

Conclusions:

The study concludes that irisin administration can replicate the effects of long-term endurance exercise on HSP70 and miR-223a and may have a more significant impact on their production than exercise training alone.

Published: November 2024

Recent advances of artificial intelligence (AI) in retinal imaging found its application in two major categories: discriminative and generative AI. For discriminative tasks, conventional convolutional neural networks (CNNs) are still major AI techniques. Vision transformers (ViT), inspired by the transformer architecture in natural language processing, has emerged as useful techniques for discriminating retinal images. ViT can attain excellent results when pretrained at sufficient scale and transferred to specific tasks with fewer images, compared to conventional CNN. Many studies found better performance of ViT, compared to CNN, for common tasks such as diabetic retinopathy screening on color fundus photographs (CFP) and segmentation of retinal fluid on optical coherence tomography (OCT) images. Generative Adversarial Network (GAN) is the main AI technique in generative AI in retinal imaging. Novel images generated by GAN can be applied for training AI models in imbalanced or inadequate datasets. Foundation models are also recent advances in retinal imaging. They are pretrained with huge datasets, such as millions of CFP and OCT images and fine-tuned for downstream tasks with much smaller datasets. A foundation model, RETFound, which was self-supervised and found to discriminate many eye and systemic diseases better than supervised models. Large language models are foundation models that may be applied for text-related tasks, like reports of retinal angiography. Whereas AI technology moves forward fast, real-world use of AI models moves slowly, making the gap between development and deployment even wider. Strong evidence showing AI models can prevent visual loss may be required to close this gap.

Entrepreneur Satisfaction and Challenges in the Machinga Complex Project in Dodoma City, Tanzania
Authors: Laurent Mpfubhusa , Mushi Benard
Published: November 2024

This study investigates the importance of small business entrepreneur satisfaction in ensuring the success of the Machinga Complex project. Despite the increasing implementation of development projects, there is limited understanding of the factors that influence small entrepreneurs' satisfaction with these projects. The study addressesthis gap by examining the factors that impact the satisfaction of small business entrepreneurs, specifically within the Machinga Complex in Dodoma City. A cross-sectional research design was utilized, with a sample size of 150 respondents obtained through a probability sampling method. Descriptive and probit regression analyses were employed, with the dependent variable measured on a dichotomous scale. The findings revealed that age, income level, participation in project consultation and initiation, education level, and project accessibility were statistically significant factors influencing entrepreneur satisfaction. The study also analyzed various challenges faced by these entrepreneurs at Machinga Complex. The results showed that competition from informal sectors, lack of loan accessibility, and insufficient infrastructure were the main challenges affecting the entrepreneurs. In conclusion, the study advocates for several policy recommendations, including the need to facilitate training programs specifically for Machinga entrepreneurs. It also emphasizes the importance of improving public participation in future projects and enhancing infrastructure quality to foster greater satisfaction among entrepreneurs. These efforts should be coordinated by both thegovernment and the private sector.

Araştırmada kartopu örnekleme yöntemi kullanılmış ve 13 özne ile yarı yapılandırılmış görüşme formları aracılığıyla görüşmeler sağlanmıştır. Veri analizi sürecinde tematik analiz yöntemi ve nitel veri analizi programı MAXQDA kullanılmıştır. Araştırma sonucunda; yaşanan deprem sürecinin anneler ve aileler üzerinde psikolojik, ekonomik, sosyal, akademik gibi çok boyutlu yansımalarının olduğu belirlenmiştir. Yine psikolojik yansımalar ile baş etme sürecinde annelerin çoğunluğunun “güç, güçlü olma, mücadele” algılarına bağlı olarak profesyonel destek almadıkları belirlenmiştir. Depremin çocuklar üzerinde çok boyutlu yansımalarının olduğu, depremzede annelerin “kadın” ve “anne” olmaları ile ihtiyaçlarının fazla olduğu ve yoğun sorumluluk duygusu yaşadıkları belirlenmiştir.

Bu araştırma, Türkiye’de 6 Şubat depremlerini yaşayan bireylerin, medya kullanımı ve motivasyonlarını tespit etmeyi amaçlamaktadır. Çalışmada Kullanımlar ve Doyumlar Kuramı doğrultusunda nicel bir araştırma yapılmış ve veri toplama tekniği olarak anket kullanılmıştır. Depremin yaşandığı dokuz şehrin çalışma evrenini oluşturduğu araştırmada, 317 kişilik örneklem ile anket yapılarak elde edilen verilere, One-Way Anova, Bağımsız Örneklem T-Testi, Korelasyon ve Faktör Analizi uygulanmıştır. Araştırma sonucunda bireylerin deprem sonrası yeni medyayı, geleneksel medyaya göre daha fazla tercih ettiği sonucuna ulaşılmış olup, kişilerin medyayı, sosyal ve duygusal bütünleşme, gerçeklerden kaçış ve bilişsel ihtiyaçlar için kullandığı ortaya çıkmıştır. Medya kullanımı bağlamında bireylerin yaş ve mesleklerine göre farklılaşmalar olduğu tespit edilirken, cinsiyete göre bir farkın olmadığı tespit edilmiştir.
Düşey ve Deprem Yükleri Altında Tünel Kalıp Sistemli Bir Binanın Farklı Temel-Zemin Modellerine Göre Analizi

Published: November 2024

Bu çalışmada 8 katlı tünel kalıp taşıyıcı sisteme sahip bina sonlu elemanlar metodu ile analiz edilmiştir. Yapı-temel sistemi için üç farklı zemin profili (ZC, ZD, ZE), üç farklı yükleme koşulu (1.4G+1.6Q; G+Q+EX, G+Q+EY) ve iki farklı temel modellemesi (ankastre çözüm, Winkler metodu) dikkate alınmıştır. Analiz sonucuna deprem kuvvetleri, tasarım ivme değerleri, periyodlar, zemin gerilmeleri, temeldeki oturmalar, kat deplasmanları ve perde tasarım kuvvetlerindeki değişim karşılaştırılmıştır. ZC’den ZE zemin sınıfına doğru gidildikçe TA ve TB arasındaki fark büyüdüğü için, ZE sınıfı zemin üzerine yapılacak yapıların maksimum ivmeye maruz kalma ihtimali diğer zemin sınıflarına göre daha fazladır. Ayrıca, ZE zemin sınıfı üzerine inşa edilen yapının periyodu Winkler yönteminde %75 daha fazla bulunmuştur. Bu artış deprem kuvvetlerinin artmasına neden olmaktadır. Yapıya etkiyen en büyük ivme sırasıyla ZE, ZD ve ZC zemin sınıfında olmuştur. Ankastre çözümde azaltılmış tasarım ivme değerleri Winkler yöntemine göre çözümden daha fazla olmuştur. Bu sebeple yapı-temel etkileşimini dikkate alan çözüm deprem kuvvetleri açısından daha ekonomik çözüm sunmakta fakat deplasmanlar daha fazla olmaktadır. Perde duvarların yalnız Eğik Çatlama Dayanımı (Vcr) bile deprem kuvvetinin üzerinde kalmaktadır. Bu durum tünel kalıp sistemlerin deprem etkisinde iyi performans göstermesini açıklamaktadır. ZC zemin sınıfında, düşey yükler altında oluşan gerilmeler ZE zemin sınıfına göre %25 daha fazladır. Deprem durumunda ise bu artış %50'ye kadar çıkmaktadır. Buna karşılık oturma değerleri artmaktadır.
FUNGAL DETERIORATION OF MONUMENT WITH REFERENCE TO QUEEN'S MOSQUE AND TOMB AT SARANGPUR, AHMEDABAD, INDIA
Authors: Gupta Sanjay Prasad , Agnihotri Sachin Kumar
Published: November 2024

Fungi have an important role in the biodegradation of monuments made of stone. The effect of fungi in the degradation of different types of stone has been widely investigated and demonstrated. Fungi can provide bio-protection for stone surfaces, act as a barrier against weathering, retain moisture, increase waterproofing, reduce thermal stress and corrosion, and absorb pollutants. Nevertheless, the evaluation of biodegradation versus bio-preservation cannot be generalized, as it may vary according to the behavior of different species, as well as that degradation may be influenced by both the lithotype and the environment. In addition to laboratory studies, more field studies of biological communities are needed, in order to analyze their establishment and succession under natural conditions and after conservation treatments. To guarantee the best decision for stone conservation, cleaning operations should not be based on a generalized approach, but on a careful evaluation of different aspects related to biodegradation and bio-preservation. In this research article, authors attempted to discuss the fungal degradation of the stone monuments i.e. Queen's mosque and Tomb at Sarangpur, Ahmedabad, Gujarat State and the role of said various fungi in the degradation based on a study jointly conducted by chemists from the Science Branch of Archaeological Survey of India, Vadodara and scientists from the National Research Laboratory for Conservation of Cultural Property, Lucknow
TRÊS VETORES DO NEGATIVO NA TEORIA ESTÉTICA DE THEODOR W. ADORNO: O FEIO, A DISSONÂNCIA E A LINGUAGEM DO SOFRIMENTO
Authors: Freitas Verlaine , Oliveira Giullia Rezende de
Published: November 2024

O objetivo do texto é fazer uma análise de três índices conceituais de negatividade na Teoria estética de Theodor Adorno: o feio, a dissonância e a linguagem do sofrimento. Inicialmente, abordaremos a problemática da autonomia estética perante o negativo em termos gerais e ligado a cada um desses três vetores; ela será examinada em função da lógica interna de constituição do artefato,considerando a dimensão dialética de seu vínculo com a negatividade do mundo, a saber, o entrelaçamento da responsabilização pela denúncia dessa negatividade e o imperativo de se manter como mera imagem, recusando uma intervenção direta no real. Em seguida, cada um daqueles vetores será analisado a partir de sua conexão com a expressividade estética, particularmente em virtude domodo como a mediação formal é capaz de assimilar em si os princípios de síntese reinantes na realidade empírica e de elevar a negatividade recalcada pela racionalidade instrumental a uma forma de vocalização sui generis. O feio será abordado em virtude da lógica histórica de sua relação com a beleza, ressaltando-se o quanto a autonomização do feio se conjuga com a autonomização da própria arte. A dissonância será analisada pelo viés de uma expressividade radical, ínsita no caráter ficcional-mimético da arte, momento em que a vida se exprime como dor e a forma artística reflete, de modo refratado, esse núcleo vital. Por fim, a linguagem do sofrimento será vista como aglutinando diversos aspectos levantados ao longo do ensaio, delineando a expressividade da arte como intimamente conectada à denúncia do sofrimento ao mesmo tempo produzido e silenciado pela dominação social.
