Published: August 2024

O propósito deste trabalho consiste em compreender a relação entre a religiosidade e a intenção empreendedora dos estudantes de uma Universidade Pública. Com base em uma amostra de 145 acadêmicos, utiliza-se um questionário, em escala likert, para mensurar as variáveis em estudos, modelo adaptado de Paiva et al. (2020). Os resultados do estudo indicam, em relação ao perfil dos alunos, que há um equilíbrio no quantitativo de homens e mulheres, com predominância do estado civil solteiro(a) e maioria com faixa etária de 16 a 20 anos. A amostra sugere que tanto os familiares empreendedores quanto a disciplina de empreendedorismo são capazes de incentivar a intenção empreendedora. Todavia, a prática da religião reconhece os praticantes como os que não sinalizam ter intenção empreendedora divergindo dos que não praticam. Os resultados quantificam a religião evangélica como a prevalecente entre os respondentes com intenção empreendedora. O período letivo evidencia o segundo semestre como o maior indicador expressivo de intenção empreendedora dentre os questionados. Contudo, encontrou-se dentro do total da amostra a quantidade de oito alunos que já são empreendedores. A realização da pesquisa foi favorável aos docentes evidenciando que o incentivo a disciplinas que foquem o empreendedorismo são cada vez mais capazes de incentivar os discentes.

Background: Depression is a prevalent and debilitating mental health condition that disproportionately affects older adults. Physical activity (PA) has been shown to have a protective effect against depression in various populations, including older adults. However, the strength and mechanisms of this association remain unclear. Objective: This study aimed to replicate and extend the findings of Rothon et al. (2010) by investigating the association between physical activity and depressive symptoms in a larger sample of older adults from the Brazilian longitudinal study of aging (ELSI). Methods: We conducted a cross-sectional analysis using data from the second wave (2019-2021) of the ELSI-Brazil, a population-based study of individuals aged 50+. Self-reported physical activity levels and depressive symptoms (assessed through questionnaires (CES-D scores) and physician diagnoses) were evaluated in 6,974 participants. Statistical analyses included descriptive statistics, multivariate logistic regression adjusted for confounders, assessment of model fit, and sensitivity analyses to assess the robustness of our findings. Results: Weekly physical activity was linked to lower diagnosed depression risk (OR=0.61) and appeared robust to confounding. Interestingly, it was not linked to daily depressive symptoms (CES-D scores). Sleep problems, pain, and race (diagnosed depression) were risk factors—social life and having a partner protected against depressive symptoms (CES-D scores). Conclusions: Our findings support prior research suggesting a link between PA and lower depression risk in older adults. The cross-sectional design limits causal inferences and the possibility of residual confounding. Future longitudinal studies are needed to explore causality and mechanisms.
Efficacy of Omega-3 in Improving Sleep Quality of Healthcare Workers with Shiftwork Sleep Disorder: Phase III, Double-blind, Placebo-controlled Trial Study Protocol (SLEEP-O3 Trial)
Authors: Sequeira María Lucía ,   Principles and Practice of Clinical Research, Harvard T.H. Chan School of Public Health, Boston, MA, USA
Published: August 2024

Introduction: Healthcare workers are especially vulnerable to sleep disturbances, including shift work sleep disorder (SWSD). Even though omega-3 supplementation has been studied to enhance sleep quality in different populations, there is lack of evidence to support its effectiveness in SWSD. This trial aims to evaluate this compound potential benefits towards health care personnel suffering from SWSD. Methods: This study protocol consists of a phase III, single-center, double-blind, placebo-controlled randomized clinical trial. Participants will receive sleep hygiene orientation in addition to either omega-3 dietary supplementation or placebo for 8 weeks. The primary outcome will be sleep quality as measured by the Pittsburgh Sleep Quality Index and one of the secondary outcomes would be actigraphy as a reliable sleep assessment. The sample size will be 136 subjects. Discussion: The importance of improving sleep quality of health care workers relies on its impact on their wellness, and on patient safety. Sleep deprivation and disorders are responsible for multiple workplace errors and worse health outcomes alike. This trial can help determine if omega-3 supplementation can contribute to ameliorate sleep disturbances in health care professionals.

Published: August 2024

Objective: To evaluate the efficacy of InstaPRESERVETM for replacing formalin in histopathology.
Methods: Tissue from seven organs from a pig was fixed with InstaPRESERVETM and formalin for 6 h, 12 h, and 24 h. Microtome sections at three time points were stained with hematoxylin and eosin and evaluated for intactness, and nuclear and cytoplasmic staining. Scoring was done based on their quality.
Results: Gross findings were well appreciated for the tissue specimens fixed with InstaPRESERVETM compared to formalin. Unlike formalin, discoloration was lesser and the rigidity was mild to firm with InstaPRESERVETM fixation. The penetration rate of InstaPRESERVETM was equivalent to formalin and the morphology and intactness were well preserved. The nuclear and cytoplasmic H and E staining intensity of InstaPRESERVETM fixed tissues was comparable to formalin fixation.
Conclusion: The promising results from InstaPRESERVETM fixed tissues of pig organs are encouraging. This preliminary study is positive on replacing formalin in routine histopathology thus preventing the pathology laboratory personnel from occupational hazards. Further studies with human specimens are required to escalate InstaPRESERVETM to medical histopathology.

Authors: PARTHASARATHY RAMA , SUNNY ANITA ANN
Published: August 2024

Objective: This study was conducted to investigate the antibiotic usage, risk factors and mortality associated with the development of VAP (Ventilator Associated Pneumonia).
Methods: An open–labelled, prospective, observational (case-control) study was carried out for 6 mo in the Department of Critical Care Medicine. Initial screening was done based on inclusion and exclusion criteria and 58 patients were found eligible. The statistical analysis was done using the Chi-Square test and t-test.
Results: The incidence of VAP in our study was 6.07%. Prolonged hospitalisation (p=0.00) and ICU stay (p=0.00) showed a statistically significant association with the development of VAP and they possessed a high risk of carbapenem-resistant organisms in the age group more than 60 years. Colistin therapy alone and/or combined with tigecycline therapy showed 100% survival. SOFA (Sequential Organ Failure Assessment) scoring done before and after VAP diagnosis showed a significant difference (p<0.005). Our study revealed that mortality was high in patients with SOFA score range of 7-9.
Conclusion: The lower incidence of VAP points out the good infection control practices in the ICU (Intensive Care Unit). Late-onset VAP was more prevalent with Acinetobacter baumannii. Prolonged hospitalization and ICU stay were the significant risk factors. Colistin therapy alone and/or in combination with tigecycline was the most effective treatment.

Published: August 2024

Objective: This research aims to isolate cellulase-producing microbes from ruminants and investigate their potential for bioremediation of organic wastes, like sanitary napkins. Organic waste management is a critical environmental challenge, and bioremediation offers a sustainable approach for waste treatment. Ruminant animals possess a unique microbial population in their digestive systems that can efficiently degrade cellulose, a major component of sanitary napkins.
Methods: In this study, samples of garden soil, cow dung, buffalo dung, and dumping yard soil were collected and screened for cellulase-producing microbes using Carboxy Methyl Cellulose (CMC) agar medium. Subsequently, the cellulase-producing microbes were employed in the whattman filter paper degradation and their capacity to degrade the cellulose in it by performing a DNSA assay. Furthermore, these isolates were employed in the bioremediation process to degrade sanitary napkins. Thereafter, we prepared various consortia of the isolates to check if it led to better degradation of sanitary napkins.
Results: The results demonstrated the successful isolation of cellulase-producing microbes from all the samples using CMC agar medium and were labeled as Isolates 1, 2, 3, 4, G, and D. In the filter paper degradation assay, isolate 3 produced the highest amount of reducing sugar from 0.1 g of cellulose, followed by isolate G, indicating the highest cellulase or FPase activity among all isolates. Additionally, these isolates exhibited promising potential for the degradation of sanitary napkins. Tube with isolate 3 had the highest concentration of reducing sugar and the lowest dry weight of sanitary napkin, followed by isolate G. Isolates 3 and G showed promising results as compared to the other isolates, but isolated 3 had an antagonistic effect when it was used with other isolates in the consortium. In contrast, isolate G showed synergistic effects in the consortium, and G+D showed the highest degradation of sanitary napkins.
Conclusion: This research contributes a microbial-based bioremediation approach to the development of sustainable and environmentally friendly strategies for waste management.
Aprovechamiento energético del estiércol de mamíferos carnívoros y herbívoros silvestres bajo el cuidado humano a través de la digestión anaerobia
Authors: Molina Arízaga María Cristina
Published: August 2024

El objetivo de la investigación fue determinar la viabilidad del estiércol de mamíferos carnívoros y herbívoros como fuente de energía alternativa en el bioparque Amaru mediante la digestión anaerobia. Se evaluaron todos los mamíferos del parque y sus recintos para seleccionar aquellos de los que se podría recolectar estiércol para el experimento. A partir de la cantidad de estiércol producido por semana, se formuló una serie de mezclas de estiércol que incluían diferentes proporciones de animales herbívoros y carnívoros. Se encontró que la producción de biogás fue mayor a partir de sustratos de estiércol herbívoro, sin embargo, los análisis de laboratorio mostraron que la cantidad de metano contenida en el gas correspondía al 3,41%, lo que no es suficiente para ser considerado biogás. Además, se observó que la relación carbono nitrógeno en la mezcla de estiércol de los animales carnívoros es muy pobre, lo que inhibe la producción de biogás. En conclusión, bajo las condiciones del experimento, no es posible suplir los requerimientos energéticos del bioparque Amaru.

Published: August 2024

La crisis ambiental que generó la emergencia por COVID-19, por su alto contagio, provocó la implementación de medidas de precaución como el uso excesivo y obligatorio de plásticos de un solo uso (PSU), materiales que, a pesar de su gran utilidad, no son biodegradables. La contaminación por basura plástica ya era un tópico de interés previo a la pandemia y aunque es totalmente admisible que los temas referentes a la salud sean prioritarios, la permanencia de algunos materiales plásticos de un solo uso en el medio ambiente ha aumentado. Una mala gestión de residuos significa el ingreso en los océanos de millones de desechos plásticos, que a su vez podrían ser vectores de diversos contaminantes, especies invasoras y patógenos relacionado con enfermedades zoonóticas. Esta revisión se llevó a cabo a partir de portales EBSCO, ScienceDirect y Scopus; redes de revistas científicas, y repositorios digitales de diferentes entidades no gubernamentales, siendo el buscador Google Scholar el más utilizado, obteniendo como resultado la revisión de 116 documentos, que permitieron proporcionar información acerca de la importancia de la disminución de los PSUs y los posibles efectos ambientales postpandémicos, además de promover planes de educación sobre la contaminación plástica.

Published: August 2024

Abstract: Doctors are usually needed to work at every hospital and emergency center every now and then. But it is not feasible for every doctor to be available at every place at desired time. The problem with video calling is that video calls need to be done from a PC or laptop on a desk. This limits the doctor’s capacity to view patient or around operation theatre at will or even move through hospital rooms as needed. To help solve this issue we here develop a virtual doctor robot that allows a doctor to virtually move around at a remote location at will and even talk to people at remote location as desired. This robot provides a whole lot of advantages for doctors: Doctors’ ability to be at anyplace anytime, Doctors can move around in operation theatres, Doctors can move around the patient with ease, Doctors can see medical reports remotely via video calls, Doctors can move around in other rooms at will. The system makes use of a robotic vehicle with 4-wheel drive for easy navigation. The robot also includes a controller box for circuitry and a mounting to hold a mobile phone or tablet. The mobile or tablet is used to hold live video calls. The doctor can use an IOT based panel to control the robot. The control commands sent online are received by the robot controller. The robot controller operates over Wi-Fi internet. The received commands are received in real time and the robot motors are operated to achieve the desired movement commands.
Automated Restoration of Damaged Character Photographs Using a Novel GAN Architecture: A Comprehensive Three-Step Pipeline for Enhanced Image Quality and Efficiency
Authors: Pallikonda Reyansh
Published: August 2024

Abstract: Restoring damaged character photographs (DCPs) is essential for preserving cultural and personal memories, yet traditional methods are labor-intensive and often require significant manual intervention. The degradation of photographs due to factors such as creases, spots, water damage, and exposure to light poses a considerable challenge to conventional restoration techniques. Manual restoration, typically performed using software like Photoshop, is not only time-consuming but also demands a high level of expertise and meticulous effort, making it impractical for large-scale applications. In this study, we propose an innovative solution to automate the restoration process by employing a practical generative adversarial network (GAN) architecture. Our approach addresses the limitations of traditional methods and aims to significantly reduce the time and effort required for photo restoration while improving the quality of the restored images. The proposed method comprises a novel three-step pipeline designed to tackle the complexities of DCPs effectively. First, we initiate the process by collecting a diverse dataset, including clear character photographs (CCPs), real DCPs, and dirty masks that illustrate common damage patterns. This comprehensive dataset forms the foundation for training our models. Second, we utilize a Residual U-Net GAN (RUGAN) to learn the spoilage patterns of DCPs and generate realistic fake DCPs from the CCPs and dirty masks. RUGAN leverages the structural and textural information from the clear images and dirty masks to produce fake damaged images that closely mimic real-world damage. Finally, we train a restoration model known as the Residual U-Net conditional GAN (RUCGAN) using the paired fake DCPs and CCPs.

The primary goal of database security is to prevent unauthorized access and data modification while ensuring uninterrupted access to required services. Various security measures have been devised to safeguard databases, and numerous security models have been established, each focusing on different aspects of database security. The effectiveness of these security measures relies on the design and development of the database management system for protection. In the current environment where web applications with databases as a backend are proliferating, a secure database management system is vital, going beyond just securing the database itself. This paper focuses on database breaches, identifying the risks, security measures, and weaknesses in managing a Database Management System.
Detecting Fraudulent Job Postings: An Analysis of Machine Learning Approaches
Authors: Razaq Rozia
Published: August 2024

Abstract: The rise of online job platforms has greatly simplified the global job search process for millions of individuals. However, this convenience has also led to a concerning issue - an increase in fraudulent job postings. Job seekers are becoming more susceptible to scams, identity theft, and financial fraud as malicious entities post deceptive job advertisements. This paper conducts a thorough analysis of machine learning approaches aimed at detecting fraudulent job postings, with the main goal of improving the legitimacy and safety of online job markets. The study encompasses data collection, preprocessing, feature engineering, model selection, and evaluation. To tackle these challenges, we explore the effectiveness of various machine learning models, including Decision Trees, Random Forests, and Support Vector Machines (SVM). Additionally, we investigate data preprocessing techniques such as label encoding and standardization to prepare the data for modeling. The results suggest that while Decision Trees and Random Forests show promising performance, dealing with the imbalanced nature of the dataset requires the application of oversampling techniques for enhanced accuracy in identifying fraudulent postings. The paper provides a comprehensive evaluation of model performance, utilizing metrics like accuracy, F1-score, precision, and recall. Furthermore, it emphasizes the significance of strategies to handle class imbalance in real-world applications

In this paper, we analyze the context of the novella “Gurvan khüükhen (Three Girls)” by Yadamsüren Mӧrdendev, known as the Mongolian literary figure of the modern era, and interpret the implications of this. To gain a deep comprehension of any text, it’s crucial to thoroughly examine its contexts, including history, social phenomena, stratification, political ideology, religious beliefs, and cultural symbols. We analyzed and interpreted the literary, social, political, cultural, economic, women’s, and author’s contexts and their role in the novella. The plot of the novella “Gurvan khüükhen”, first published in 1936, begins with the action of the female character “leaving the home” and shows the situation of Mongols at the beginning of the revolution, the old and new social ideology. In doing this, the female body is objectified, symbolizing the inevitable decline of the old society through the portrayal of Zandanbal. She becomes immersed in the old city’s life, trapped in its wounds, and ultimately perishes. Conversely, the advancements of the new society are embodied by the teacher Khorolmaa, while the societal transition’s missteps are exemplified by Khas-Erdene. The portrayal of how representatives from both the old and new societies influence women’s independent decision-making and education is shaped by various social, cultural, political, and economic contexts.

When the state symbolism of the Bogd Khanate of Mongolia was created, a dual state symbolism was adopted incorporating both Mongolian state symbolism originating from the era of the Hunnu Empire and state symbolism originating in ancient India. The state symbols of the Bogd Khanate of Mongolia may be classified into two types by legal status, official and unofficial. Where the official symbolism included the three symbols of the state emblem, state flag, and state seal enacted in the “Mongolian Legal Rescript Enacted by Decree,” the unofficial symbolism included symbols like the national anthem and the Seven Imperial Treasures that were used despite not being legally enacted. As for the specific features of the state symbolism of the Bogd Khanate, they consisted in raising the majesty and authority of the absolutist, theocratic khan, as shown by each symbol, as well as adopting ancient Indian state and religious symbolism and reflecting international norms, thereby asserting Mongolia’s status as an independent sovereign nation.

The “Morin Khuur”, one of the traditional musical instruments of the Mongolian nation has been modified and updated over the centuries. Along with this, its name has also changed, and today we mostly use the popular name “Morin Khuur”. On the one hand, it seems to be widely recognized as one of the Mongolian folk musical instruments, and to be known to the world, but there are some shortcomings such as forgetting and not using the previous names, and misinterpreting the differences. On the other hand, we consider it important to reuse the old names of the “Morin Khuur” and similar musical instruments, and to use them for naming newly made musical instruments according to old sources and the era in which they were used. Correct use of names within the framework of its origin is important for the further development and renewal of Mongolian traditional musical instruments. In this article, we intend to explain each of the names created as a result of renewing the “Morin Khuur”, and to suggest some opinions on how to use them.

Considering the theme of Artai’s poem, the poet of the Mongolian ethnic group, a small minority in China, he has a “mine” that preserves the great energy of the motherland and the people, as well as love, happiness and sadness. Every time you read Artai’s poems, you will be overwhelmed by the power of magic, that is embedded in every line of the poem. This is the awakening of thought and the power of language. Writing poetry in Mongolian is a praise of his today’s great merit. There are quite a few poems with a simple tone and style in Artai’s poetry. However, those poems with simple language are written with a deep meaning towards the people and the nation. His artistic language, which contains the color of the Mongolian mentality, teaches about the love of Mongolian traditions and heritage.

Since the establishment of the Inner Mongolia Autonomous Region of the People’s Republic of China in 1947, there have been many changes in the social and cultural life of Inner Mongolia. Among them, “Ulaan Tchihir” and art groups for cultural and artistic activities were established in cities and rural areas. Since then, on the one hand, Mongolian ethnic identity based on traditional culture, on the other hand, civic identity reflects the influence of China’s policy and culture, and a distinctive culture of Inner Mongolia, which is different from other Mongolian ethnic groups, have been formed. As a result, it was reflected in culture and artworks and attracted the attention of domestic and foreign audiences. An example of this can be considered the performance of the song and dance theater of Hoh city, including dance music. In this study, the theater’s “Ovgod” dance performance was analyzed, and the features of Inner Mongolia reflected in the dance and musical elements of the performance were analyzed. In doing so, in addition to textual analysis of the works, interviews were conducted with the artists and analyzed in comparison with previous research. In this study, the formation of the “Inner Mongolian” cultural identity, which is caused by the history, society and culture of Inner Mongolia, was considered.

Field research of local dialects in Mongolia intensified during 1955-1970s and consequently several works on the classification of local dialects were published. When these works were analyzed, some local dialects were classified into Buryat, Oirat or Khalkha groups based on ethnic origins of the speakers due to lack of sufficient source data. This was undoubtedly a significant result to some extent at that time. However, language evolves in accordance with social, historical and political circumstances. Therefore the Buryat dialect of Khuvsgul was selected as the research subject due its scarce documentation and the need for accurate classification. As a result of this research, the following conclusions were made. The local dialect of the Buryat ethnic people of Khuvsgul is: 1. a Khalkhized Buryat dialect or a Khalkha dialect with Buryat root 2. is an endangered language as it assimilated to Khalkha dialect and should be considered part of Khalkha dialect group 3. a real-world example of the influence a country’s official script and its main dialect has on local dialects. Moreover, depending on their geographical location, there are other dialects that have become Khalkhized and Oiratized. There is a need for contemporary analysis and re-classification of Mongolia’s local dialects.

The horqin region is the centre of Mongolian Epics. Among the numerous epics to be found in the horqin region, there are twenty-four (eighteen main chapters and six sub-epics), sagas that are very unique in form and content. The first Chapter of this eighteen-chapter series will be the epic Bodhi Galab Khan. The epic poem “Bodhi Galab Khan” is called the First Galab or the First Galab by the horqin Mongolians. It is thought that after this first Galab, 18 more gala periods followed. The name of these periods include the second “Altan Galab Khan”, the third “King of Ultimate Heroes”, the fourth “Knig of the Golden Stone”, the seventeenth “Imaginary Heroes”, and the seventeenth “The King of the Golden Stone”. “The Hero of Dreams”, the 18th “The Blue Bull”. It will be Horqin people call these legends and epics “eighteen stories” or “eighteen strange stories”. The first two legends, “Bodhi Galab Khan” and “Altan Galab Khan”, are epic stories because they relate the origin of the world of Galab. In the epic poem “Bodhi Galab Khan”, “Bodhi Galab Khan” along with the stone forest, fights against the horned monster with the mad hero and extols the heroics of the final victory over the monster. In this paper, we are presenting for the first time how scholars at home and abroad have collated and analysed the epic “Bodhi Galab Khan” and how they have come to divergent conclusions.

In the last decade, augmented reality has been one type of virtual reality technology. AR can be applied to mobile learning, improving efficiency and effectiveness in education, even for learning mathematics. The study aims to analyze and describe comprehensively the effect of experiential learning and direct instruction assisted by augmented reality on the acquisition and improvement of students' mathematical reasoning abilities. This research uses quantitative methods with a quasi-experimental, one-group pretest-posttest design and a pretest-posttest control group design. The sample in this study consisted of 50 students in the eighth grade at one of the secondary schools in Bandung, Indonesia. The instrument in this study is a set of mathematical reasoning ability tests. The results of this study concluded that 1) Based on the standard of the deviation, the descriptive spread of scores for achieving mathematical reasoning abilities of students learning with experiential learning assisted by augmented reality (more widespread); 2) Cohen's d value on the output paired samples effect sizes was 14.003 with a point estimate of (large) so the value of the effects sizes obtained shows that the implementation of experiential learning assisted augmented reality has a major effect on the acquisition of mathematical reasoning abilities; 3) The mean achievement of mathematical reasoning abilities of students studying with experiential learning assisted by augmented reality was 60.38 relatively lower than the mean achieving mathematics reasoning abilities of students who studied with directed instructions assisted by augmented reality, 70.33; 4) The effect size value shown by the value is -3.50, and this value is less than 0.2, so based on Cohen's d criterion, then the effect of experiential learning assisted by augmented reality on the acquisition of mathematical reasoning abilities students are in the small category. The findings combine experiential learning and directed instructions assisted by augmented reality, influencing students' reasoning ability mathematically.

Animation is a space of wonder and magic, and it can also be a place of political resistance and social awareness. Animation can be all these places simultaneously and by doing so it opens doors to different understandings of reality and an alternative consciousness of the world. This paper aims to analyze the animated short film Tragic Story with Happy Ending (2007), directed by Regina Pessoa, as a figurative path to reflect about the intersection between animation and feminism. The construction of a feminist experience in contemporary animation, specifically in Portuguese animation, is analyzed while considering a compendium of essays on women animators edited by Jane Pilling, Women & Animation (1992), and Chimamanda Ngozi Adichie’s thoughts on Feminism. The animated space in which the woman’s voice is acknowledged is also reflected upon based on the concept of “Speaking Nearby” by Trinh T. Minh-ha (1992). Tragic Story with Happy Ending does not have an explicit approach to Feminism but by revealing a wide consciousness of human nature and subtly reflecting about what it means to be a woman, a socio- political dimension and feminist experience emerge from its core.

This paper explores the development of English media in Macau, a region known for its Chinese and Portuguese language dominance. While the English media market is smaller than other languages, it caters to the English-speaking communities in Macau, including foreign migrants and immigrants. However, more research is needed on how English media influences the culturally diverse Macau under its current regime. As Macau soon celebrates its 25th anniversary since its return to China in 1999, it is fitting to examine the region's media development. This paper aims to understand the connection between the media's contribution to Macau's development and the freedom of the press. By analysing the role of English media in Macau, we can gain insights into the dynamics of a multilingual media environment and its implications for the region's cultural and social fabric. The findings of this study contribute to the existing literature on media and provide a deeper understanding of the role of English media in Macau's societal and economic progress.
