Published: November 2024

Introducción: En la sociedad, el estrés laboral se ha convertido en una de las principales preocupaciones en los lugares de trabajo, dando lugar a diversas dificultades. Sin embargo, una de las formas eficaces de aumentar la satisfacción laboral entre los empleados es minimizar los efectos negativos del estrés laboral. Objetivo: Este estudio pretende determinar la predictibilidad de la satisfacción laboral sobre el estrés laboral en jóvenes trabajadores en periodo de pandemia Covid 19. Método: Se empleó un diseño transversal predictivo, utilizando una estrategia asociativa. La muestra consistió en 173 trabajadores de una empresa de construcción, compuesta por individuos de ambos sexos con edades comprendidas entre los 18 y los 25 años. Se empleó un muestreo no probabilístico de conveniencia para seleccionar a los participantes en el estudio. Los instrumentos de investigación empleados fueron la Escala de Estrés Laboral Organizacional y el Cuestionario de Satisfacción Laboral S21/26, los cuales fueron adaptados para su uso en el Perú por García (2017) y Vásquez (2011) respectivamente. El índice de consistencia interna de los instrumentos fue determinado por las propias autoras. Resultados: Los resultados revelan que la variable satisfacción laboral demostró su capacidad para predecir variaciones en la variable estrés laboral, además que existe una relación significativa e inversa entre ambas variables. En otras palabras, mientras más alto sea el puntaje obtenido en satisfacción laboral menor será la puntuación en estrés laboral. Conclusiones: De estos resultados se deduce que, cuando los trabajadores experimentan un estrés excesivo, se produce insatisfacción en su entorno laboral.

El rápido desarrollo urbano y el empleo de materiales impermeables han afectado negativamente en el ciclo hidrológico. Durante las lluvias intensas, en ciudades con la infraestructura inadecuada, las redes de alcantarillado colapsan. Esto conlleva al deterioro de los pavimentos generando incomodidad y peligros como el hidroplaneo impactando en el tránsito de peatones y conductores. Para abordar estos problemas, se ha demostrado que el concreto permeable es un material adecuado debido a que permite que el agua fluya a través de sus poros además de ser ecológico y sostenible. Sin embargo, su uso en pavimentos rígidos es limitado ya que su resistencia es menor a la del concreto convencional. Por lo que la inclusión de microsílice y fibras de basalto mejorarían su desempeño mecánico. El área de estudio corresponde al distrito de Wanchaq - Cusco, la cual es afectada por las precipitaciones pluviales intensas y un sistema de alcantarillado combinado que rebasa su capacidad durante la época de lluvias. El suelo del área de estudio es de grava y la infiltración requerida es de 186.2 mm/h con un periodo de retorno de 10 años. Se realizaron 4 diseños de mezcla de concreto permeable con microsílice en un 9.5% del peso del cemento, con adición de fibras de basalto en porcentajes de 0%, 0.1%, 0.2% y 0.3% respecto al volumen de la mezcla. Además, se muestra la comparación del costo del concreto permeable con microsílice reforzado con fibras de basalto frente al concreto permeable convencional. Finalmente se realizó la validación de los resultados mediante ensayos de compresión, flexión y permeabilidad cuyos resultados señalan como mezcla óptima al diseño de concreto permeable con fibra de basalto añadida en un 0.1%.

La aplicación de los programas de compliance como eximentes de responsabilidad penal de la persona jurídica en el marco de la Ley No 30424
Authors:   , Andrade Terán Ana Carolina
Published: November 2024

En la presente tesis, analizo en el primer capítulo la evolución del término “societas delinquere potest ” , término utilizado en la doctrina para referirse a la posibilidad de que las personas jurídicas puedan delinquir, es decir, la aceptación de la responsabilidad penal de la persona jurídica, para ello realice una investigación histórica la cual me permitió conocer a partir de que siglo se reconoce que las personas jurídicas si pueden cometer delitos. Además, en el primer capítulo estudio los modelos políticos criminales para atribuir la responsabilidad penal de la persona jurídica, así como los fundamentos doctrinales que respaldan la aplicación de responsabilidad penal a las personas jurídicas. En el segundo capítulo de mi tesis, analizo de manera detallada la regulación en el código penal peruano de la responsabilidad penal de la persona jurídica, denominadas consecuencias accesorias, las cuales se encuentran tipificadas en el artículo 105 del código penal peruano. De manera similar, analizó la aplicación de las consecuencias accesorias en el proceso penal. Adicionalmente, realizo una investigación a la legislación comparada, específicamente de España respecto a la aplicación de las consecuencias accesorias. Por otro lado, en el tercer capítulo de mi tesis, estudio la Ley No 30424, ley denominada como la regulación de la responsabilidad administrativa de la persona jurídica en el Perú, para ello analizó los antecedentes internacionales que influyeron en la promulgación de la Ley No 30424, así como los delitos que incorpora la Ley No 30424, considerando la última modificación mediante la Ley No 31740 la cual entró en vigencia en noviembre de 2023, la misma que agrego treinta nuevos delitos. Continuando con el desarrollo de la elaboración de mi tesis, en el cuarto capítulo desarrolló un análisis completo de todos los elementos que debe contener un programa de compliance para que cumpla con la finalidad de ser efectivo y de esta manera pueda eximir de responsabilidad a la persona jurídica. El quinto capítulo de mi tesis está dirigido a las responsabilidades, por un lado, analizó los supuestos en los que la persona jurídica podrá eximirse de responsabilidad penal y los supuestos en los que no podrá eximirse de responsabilidad. De igual manera, en el capítulo cinco analizó los supuestos en los que se configura la responsabilidad del compliance officer. Por otra parte, en el sexto capítulo de mi tesis elaboró un análisis costo – beneficio de la responsabilidad de las personas jurídicas y un análisis costo – beneficio de la implementación de los programas de compliance. Finalmente, en el séptimo capítulo de mi tesis, busco innovar para que de manera adicional a un análisis teórico exista un análisis práctico, para lo cual realicé entrevistas a expertos en la materia.

Published: November 2024

Aim: Gastric cancer (GC) is one of the common malignant tumors, and most patients with advanced GC often develop chemotherapy resistance, resulting in poor chemotherapy efficacy. Therefore, it is crucial to clarify the specific mechanisms of their chemotherapy resistance.

Methods: In this study, we analyzed the correlation between fos-related antigen-1 (Fra-1) and chemotherapy resistance in GC using bioinformatics, cell counting kit-8 (CCK8), and 5-ethynyl-2’-deoxyuridine (EDU) combined with flow cytometry; furthermore, we used energy metabolomics sequencing, combined with ChIP-qPCR technology, to elucidate the specific role of Fra-1 in chemotherapy resistance of GC cells and its related mechanisms.

Results: We found that high Fra-1 expression was closely related to chemotherapeutic drugs in GC cells, as demonstrated by bioinformatics analysis combined with EDU and CCK8 experiments. Energy metabolomics combined with in vitro cellular experimental analysis revealed that the pentose phosphate pathway (PPP) was activated in GC cells with high Fra-1 expression, along with an increase in the synthesis of metabolites such as nicotinamide adenine dinucleotide phosphate (NADPH) and glutathione (GSH), a decrease in the level of reactive oxygen species (ROS), and the inhibition of their ferroptosis. In addition, ChIP-qPCR experiments confirmed that Fra-1 binds to the promoter of glucose-6-phosphate dehydrogenase (G6PD), a key rate-limiting enzyme of the PPP, and transcriptionally regulates its expression, which in turn activates the PPP and promotes chemotherapy resistance in GC cells.

Conclusion: Our research findings suggest that Fra-1 activates the PPP by upregulating G6PD transcriptional activity and inhibiting its ubiquitination level, inhibiting ferroptosis in GC cells and inducing chemoresistance. This provides an experimental basis for screening potential molecular targets for chemotherapy resistance in GC patients.

Published: November 2024

Crystal plasticity (CP) simulation is a powerful tool for studying and understanding the mechanical behavior of materials. A critical aspect of this method is the accurate determination of CP parameters, which ensures that the constitutive model accurately represents the real deformation behavior of a material, especially in high-fidelity simulations. However, identifying these parameters poses a significant challenge due to the high computational cost and the difficulty of finding optimal solutions within a vast and complex parameter space. To address these challenges, we propose a fast search strategy that leverages active learning (AL) and experimental data to accelerate the optimization of CP parameters. Using the Al-Cu eutectic materials as a case study, we introduced a quantitative index, C ecp, to measure the consistency between simulated and experimental stress-strain curves. We demonstrated that Gaussian process regression (GPR) serves as the most appropriate surrogate model for relating CP parameters and C ecp based on our dataset. After only six iterations guided by AL, the optimal CP parameters were successfully identified, resulting in a high-fidelity CP model for analyzing the mechanical behavior of Al-Cu eutectic materials. The machine learning-enhanced strategy is far superior to traditional methods in terms of both efficiency and accuracy. It advances our understanding of the macro-micro relationships of materials and accelerates the material design process.
Leveraging Deep Learning for Personalized Book Recommendations: A Big Data Algorithm Combining Capsule Networks and Attention Mechanisms
Authors: Liao Jiali , Li Tianxiang
Published: November 2024

In the era of big data, personalized book recommendations have become crucial for enhancing user satisfaction and improving information retrieval efficiency. This study addresses the limitations of existing book recommendation algorithms by proposing a novel Hybrid Book Recommendation Algorithm Considering Different Preferences (HBRACDP). Our approach integrates Capsule Networks and Self-Attention Mechanisms to model both short-term and long-term user borrowing preferences. We construct separate models for these preferences and combine them using a controllable multi-interest network with label attention. Experimental results on the Goodreads dataset demonstrate the superiority of HBRACDP, achieving an accuracy of 0.984, recall of 0.987, and F1 score of 0.988 in ablation tests. In practical scenarios with 1000 students, HBRACDP significantly outperformed traditional algorithms, with a recommendation accuracy of 97.89% and an error rate of only 0.08%. This study provides new insights for developing more accurate and efficient big data recommendation systems in library services and beyond.

Background: Infants of diabetic mothers (IDMs) face heightened risks of various neonatal complications. This study evaluates the incidence of specific complications-macrosomia, hypoglycaemia, and neonatal respiratory distress syndrome (NRDS)-in this population. Methods: A cross-sectional observational study was conducted over 1.5 years at a tertiary hospital in Mumbai. We reviewed the medical records of infants born to mothers with diabetes (both pregestational and gestational). Data on the incidence of macrosomia (birth weight >4000 grams), hypoglycaemia (blood glucose <40 mg/dL), and NRDS (diagnosed based on clinical and radiographic criteria) were collected. Results: Among the 50 infants studied, 8% were diagnosed with macrosomia, 46% experienced hypoglycaemia, and 20% developed NRDS. The frequency of these complications was significantly higher in IDMs compared to the general neonatal population. Conclusion: This study reveals a high incidence of macrosomia, hypoglycaemia, and NRDS in IDMs, emphasizing the need for regular antenatal follow-up and strict glycaemic control throughout pregnancy. Enhanced monitoring and management strategies are essential to mitigate these risks and improve neonatal health outcomes.

Background: Bladder stones are a rare pathological condition in women, often secondary to any etiology. Further investigations are required to identify the various factors involved in their formation and the complications they cause. For a woman, the appearance of a bladder stone following a predisposing factor, in particular an intra-vesical foreign body is a source of recurrent urinary tract infections and calculus, manifested by dysuria and hypogastric heaviness. This study aimed to describe the case of the formation of a bladder calculus from the presence of a non-absorbable suture. Case presentation: The case of a 30-year-old woman with a bladder stone causing several recurrent urogenital infections despite years of medical treatment is reported. After several additional para-clinical investigations, an ultrasound diagnosis of a bladder stone with pre-renal failure was established. The patient underwent a median exploratory laparotomy below the umbilicus for surgical management, followed by an open cystolithotomy with the extraction of a large bladder stone on which an old suture was implanted, probably as a result of the previous cesarean section. Conclusion: Bladder stones are rare, but relatively rare in our environment, with limited diagnostic resources. In this case, it appears that the non-absorbable suture was inadvertently placed in the bladder during the cesarean section, which has unfortunately contributed to recurrent urogenital infections and the formation of bladder calculus.

This research examines the effect of JobEmbeddedness (JE) on turnover intentions (TI) among staff in the hotel industry of Uttarakhand, India. JE, including Fit, Links, and Sacrifice, has become a crucial paradigm for comprehending employee retention. A quantitative technique was employed to collect data from 79 employees across eight hotels. A multiple regression analysis was performed to examine the impact of the dimensions of JE on turnover intention. Results indicate that all three aspects of job embeddedness substantially diminish turnover intention, with Sacrifice exerting the most pronounced influence. Employees who recognize significant compromises associated with leaving, such as the forfeiture of perks and relationships, are the least inclined to indicate intentions to resign. Fit and Links are essential, as a robust alignment between personal values and organization, along with social relationships in the workplace, leads to reduced turnover intentions. The research highlights the significance of incorporating job embeddedness into retention tactics, especially in high-turnover sectors such as hospitality. By concentrating on the aspects of Sacrifice, Fit, and Links, hotel managers can bolster employee retention, diminish turnover expenses, and augment organizational stability. These findings provide significant insights for HR professionals and enhance the prevailing literature on JE and turnover in labor-intensive sectors.

This article examines the financial performance and growth trajectory of State Cooperative Banks (SCBs) in India from 2012-13 to 2022-23, focusing on key indicators such as deposits, loans, borrowings, investments, and working capital. The study highlights the significant growth in these areas, driven by increased member engagement and trust. However, opportunities for further improvement remain, particularly in the areas of deposit mobilization, loan management, and investment diversification. SCBs can capitalize on these opportunities by introducing targeted savings products for rural populations, expanding digital banking services, implementing advanced risk management practices, and optimizing working capital. The study also emphasizes the need for SCBs to expand their network into underserved rural areas, leveraging technology for financial inclusion. By addressing these growth opportunities and challenges, SCBs can enhance their operational efficiency, financial stability, and contribution to rural development.

Milk and Milk Product market of the state of Kerala is growing at fast and various national and global players are competing in the market to get the key share. From the inception itself the products of Milma are the most favoured products of the consumers in Kerala. However, the presence of Dairy Cooperatives from other state may affect the existing demand for their product. It aims to study the buying behaviour of the consumers of milk and milk products of Milma along with their awareness and attitude towards the product. This study is based on the descriptive study and statistical tools used are percentages, mean score and Mann Whitney U Test. Data is collected from 120 consumers of the product from Thrissur district, the centre of Kerala by convenience method. The variables taken for studying the buying behaviour are the reasons for buying, frequency of buying, source of buying, type of milk using, quantity of milk bought once etc. It suggests that consumers are more familiar with staple dairy products, while specialized items have lower awareness, potentially pointing to opportunities for targeted marketing. It finds the important attribute they feel favour the Mima products are quality, products of cooperatives, brand image, freshness and nearly available. The study is useful to the marketer while introducing marketing programs that they believe will influence the consumers.

Published: November 2024

This review evaluates the effectiveness of metal–organic frameworks (MOFs) in treating dye wastewater. MOFs are highly effective in dye effluent removal due to their multifunctionality, water stability, and recyclability. They offer exceptional dye removal and degradation capabilities, with significant surface area and adjustable pore size. Among various dye removal techniques (chemical, physical, and biological), adsorption has emerged as a cost-effective and highly efficient method. Researchers analyse adsorption isotherms and kinetics to understand the efficiency of MOFs in dye absorption from wastewater. Characterization studies confirm the effectiveness of MOFs. Conventional adsorbents fall short of industrial dye removal, thus making MOFs a promising alternative. This review assesses MOFs’ efficacy in treating dye wastewater, highlighting their superior adsorption capacity over conventional materials. Various MOF types, including modified and gel-based variants, show promise. Research into inexpensive and efficient adsorbents from available resources for colour removal is increasingly vital. Studies demonstrate the efficacy of numerous affordable adsorbents in wastewater colour removal.

Introduction. This study investigates the complex interplay between dental compositions, smile styles, and personality traits in young adults seeking oral and dental care, guided by the Visagism paradigm.
Methods. A total of 150 young adult volunteers aged 18-35 years participated in the study. The participants completed a questionnaire designed to assess personality traits. A survey containing various personality characteristics was administered to determine the participants’ fundamental personality traits, with respondents encouraged to indicate the traits they most closely identified with honestly. Based on the survey responses, individuals were categorized into one of four main personality groups: melancholic/sensitive, sanguine/dynamic, choleric/strong, and phlegmatic/peaceful. Subsequently, a careful clinical examination was conducted to assess each patient’s tooth form, smile style, and the visibility of teeth and gums at different smile stages (stages III and IV). Statistical analysis was then conducted.
Results. Oval tooth forms (36%) and the commissure (Mona Lisa) smile style (72.5%) were most frequently observed, aligning with previous research. Notably, women exhibited a higher prevalence of a melancholic temperament. However, the study found no significant relationship between self-reported personality traits and dental compositions or smile styles.
Conclusions. The study did not confirm a significant association between personality traits and smile styles or dental forms. While the findings align with existing research, they highlight the complexity of the Visagism paradigm, emphasizing the need for further investigations into the relationship between temperament and dental aesthetics.

This letter provides an overview of the continent’s diversity in geography and climatic exposure and the impact of chlorides on reinforced concrete structures in North America. Several research needs are identified, including those that arise as specifications begin to change from prescriptive to performance-based approaches. Further, the widespread changes in material compositions or chloride exposures, require important changes to specifications, design practices, or maintenance procedures. Related to reducing carbon emissions, there is a need to reduce clinker content in concrete mixtures, increase the use of novel cementitious and supplementary cementitious materials (SCM), and to understand the durability of such concretes. The following research efforts from a North American context are warranted: (i) investigating the long-term durability of novel cement and SCM systems, including non-Portland cement-based materials and those made with CO2 mineralization used to meet carbon emission targets; (ii) understanding climate change impacts of temperature and sea levels, including flood impact, on chloride exposure and chloride-induced corrosion; (iii) developing rapid and reliable tests to estimate durability in practice, particularly for scaling, freeze-thaw, salt damage, and chloride-induced corrosion; and (v) developing better understanding of the short and long-term implications of changes in constituent materials and exposure.

Published: November 2024

Este artigo objetiva elucidar aproximações e diferenciações entre a racionalidade comunicativa e a análise de conteúdo. Essa discussão nasceu de uma pesquisa de mestrado realizada no Programa de Pós-Graduação em Educação da Universidade do Estado do Rio Grande do Norte (UERN). A metodologia é de abordagem qualitativa e de cunho bibliográfico. A racionalidade comunicativa assenta-se na linguagem como meio capaz de propiciar compreensões acerca dos mundos objetivo, social e subjetivo. A análise de conteúdo se caracteriza como instrumento de análise composto por procedimentos sistemáticos para a construção de inferências sobre a linguagem em suas múltiplas formas de manifestação e representação. Embora a racionalidade comunicativa e a análise de conteúdo partam de gêneses, pressupostos e objetivos diferentes, ambas admitem a linguagem como construção histórica, social e cultural, permeada e condicionada por variações contextuais e subjetivas.

Published: November 2024

Este estudo analisa a inclusão de uma abordagem historiográfica da História das Ciências nos livros didáticos de química do PNLD - 2018, com foco no norte global. Reconhecendo a importância desses materiais no Ensino de Química, investigamos como tais conteúdos são tratados neles. Defendemos que a integração da História das Ciências nos livros didáticos pode o tornar mais desafiador e crítico, assim contribuindo para o Ensino de Química, que usualmente privilegia figuras e perspectivas do norte global. Optamos pela abordagem qualitativa, utilizando a análise de conteúdo de Bardin (1995) para examinar os dados textuais coletados. Esperamos que os resultados gerem debates sobre como os livros didáticos influenciam na percepção estereotipada e centrada no norte global do Ensino de Química, ao destacar exclusivamente suas contribuições.

Este trabalho objetivou analisar a temática alimentação saudável na área de Ciências da Natureza dos nove estados do Nordeste brasileiro. Realizou-se análise documental nos quadros organizadores curriculares, que possuíam a estruturação de temas referentes à disciplina de Ciências, em busca de assuntos sobre educação alimentar e nutricional ao longo do ensino fundamental. Observou-se que no 5º ano, período escolar priorizado para os assuntos de alimentação saudável na base nacional comum curricular, uma maioria dos estados nordestinos inseriu a temática nutricional em suas escrituras. Apenas os estados de Alagoas, Paraíba, Ceará e Rio Grande do Norte abordam a alimentação saudável em outros anos, sendo que os dois últimos estados possuem temas para os anos finais. Portanto, conclui-se que é preciso avanços na abordagem da educação alimentar e nutricional no ensino fundamental, devendo ser orientada desde o documento nacional de base.
