THE STATUS OF SOCIO-HUMAN DISCIPLINES IN PRE-UNIVERSITY EDUCATION. CASE STUDY IN ROMAN, ROMANIA
Authors: POENARU Alexandra-Georgiana 
Published: February 2025

In this article, we present the results of an empirical study through which we analyzed the perception of teachers and students towards socio-human disciplines (with a case study in the municipality of Roman, Romania). We were interested in the perceptions of teachers and students regarding the importance of socio-human disciplines specific to secondary and high school levels, by applying questionnaires to a sample of 110 teachers and 133 students. Comparatively, we wanted to know if there are significant differences between teachers' and students' opinions regarding the importance of socio-human subjects, to what extent there is the perception that the socio-human field is intended for students and less for students, as well as the differences in students' opinions according to their gender, class of studies, study path and environment of residence. This analysis were doubled by in-depth documentation on the school curricula, and the direct and indirect skills that students must acquire.
Optics of Jumping Sundogs
Authors: Tufaile Alberto , Tufaile Adriana Pedrosa Biscaia 
Published: February 2025

Jumping sundogs, or crown flashes, are a rare and interesting atmospheric phenomenon characterized by beams of light dancing across the sky. Despite their rarity, social media videos have captured numerous instances of this phenomenon under seemingly similar conditions. By analyzing these videos, we have investigated the structure and dynamics of jumping sundogs. Our analysis reveals that these events require specific ice crystal types and atmospheric conditions. The distinctive feather-like luminescence of jumping sundogs is attributed to the orientation of ice crystals influenced by electric fields within the cloud. These crystals interact with sunlight, creating the observed luminous pattern. We propose that electrical charges near the base of the crown flash generate an electric field that guides the ice crystal orientation. Jumping sundogs might exhibit a “memory effect”, because in a certain temperature range, their orientation could depend on their past state (aligned), unlike the random orientation at higher temperatures. Jumping sundogs are a type of critical phenomena, where ice crystals align in a specific direction below a critical temperature and orient randomly above it.

Authors: Usman Muhammad , Lin Shengfa , He Guiqiong , Lu Hong 
Published: February 2025

IntroductionSoft tissue sarcomas (STS), representing 80% of sarcomas, are a rare and diverse group of neoplasms with a dire prognosis. Macrophages and their subtypes play an essential role with diverse outcomes in the tumor microenvironment (TME) of cancers, including sarcomas. The aim of this study was to investigate the role of macrophages in the development and prognosis of sarcoma patients.Material and methodsTranscriptomic data from 5 sarcoma cohorts including 581 patients and transcripts of 56,752 single cells from 6 sarcoma patients were retrieved from public databases and analyzed. The infiltration of immune cells in the TME was evaluated with the CIBERSORT algorithm. Kaplan-Meier estimation with the log-rank test and Cox regression hazards models were adopted for evaluation of prognostic impacts.ResultsDeconvolution of 22 types of immune cells via the CIBERSORT algorithm revealed macrophages as a prominent component of the TME of sarcoma patients. Of these, M0 was associated with worst prognosis. A six-gene prognostic signature, termed MRPS, was developed that was significantly positively correlated with M0 macrophages. The MRPS-stratified high-risk subgroup showed abundance of M0 macrophages, indicating inhibition of macrophage polarization, specifically the classically activated pro-inflammatory M1 phenotype. Moreover, enrichment of oncogenic pathways and glycolysis and high frequency of mutations were evident. The robustness of the MRPS as a predictive biomarker was validated in external soft-tissue sarcoma patient datasets. A nomogram based on MRPS was developed as a potentially accurate and practical predictive tool for identifying high-risk sarcoma patients with lower survival probabilities. Furthermore, the MRPS signature exhibited reliable predictive capabilities for immunotherapy response, suggesting its potential to enhance the effectiveness of personalized immunotherapy in sarcoma patients.ConclusionsMRPS represents a robust biomarker for predicting outcomes and response to therapy in soft-tissue sarcoma patients.

Published: February 2025

This study examined the impact of project communication practices on the performance of a child protection and education project implemented by World Vision International Rwanda (WVIR). Specifically, to assess the effect of participatory communication on performance of a child protection and education project, to examine the effect of results-driven communication on the performance of a child protection and education project and to assess the effect of feedback mechanism communication on the performance of a child protection and education project in Rutsiro district. The theories guided this study are participatory communication theory, feedback intervention theory and goal-oriented communication theory. The study employed the descriptive and correlational research design. The target population was 142 people including project coordination staff, project team implementers, project promoters, project beneficiaries. The population was small and accessible; therefore, the census method was used. The data was collected using questionnaire and interview guide. The data was analyzed using qualitative and quantitative approches, including descriptive statistics and inferential statistics using SPSS version 25.0. Qualitative data was collected through interviews and analyzed based on responses. The findings revealed strong positive agreement with participatory communication (M=4.27), results-driven communication (M=3.75), and feedback mechanism communication (M=4.16). Regression analysis showed that for every one-unit increase in participatory communication, project performance increased by 1.354 units (p=0.000), while results-driven communication and feedback mechanisms had negative effects on performance, with decreases of -2.081 and -0.163 units respectively (p=0.000). These findings suggest that participatory communication significantly improves project performance, while results-driven communication and feedback mechanisms do not. Based on these findings, it is recommended that the project shares regular the project activities designed to foster trust and open communication among stakeholders and team members. Further, project should organize a regular communication training to equip project stakeholders with effective communication strategies for example how to provide feedback communication. Additionally, the project should encourage more proactive feedback through recognition programs and ensuring feedback.
O cordel na universidade: entre folclore e cultura popular
Authors: Silva Amanda Ribeiro da , Ferro Maria do Amparo Borges 
Published: February 2025

O objetivo deste artigo é compreender o cordel dentro da universidade e sua operacionalização dentro dos moldes do folclore e da cultura popular, a partir de professores e alunos que o faziam circular nesse meio. Para compreender como o cordel transitava na universidade, foram essenciais o conceito de capital social de Bourdieu (2010) e o pensamento de outros autores que abordam tanto a temática cordelista, quanto a temática historiográfica, tais como Albuquerque Junior (2013), Foucault (2008), Chartier (1995), Melo (2019), Sousa (2020) e Ribeiro (1997), entre outros. Para atingir o objetivo desta pesquisa, foi desenvolvida, principalmente, a pesquisa documental, a partir de jornais e revistas que circulavam no Piauí, localizados no acervo do Arquivo Público Casa Anísio Britto, além de fontes orais, como entrevistas com poetas, vendedores e leitores de cordéis. Durante o período estudado, o cordel se apresentou ora como um elemento do folclore, ora como um aspecto da cultura popular, gerando um debate ideológico entre as noções conservadora e revolucionária. O cordel circulou na universidade por meio de intelectuais inseridos tanto no espaço social quanto acadêmico. É sabido que esses homens tinham um papel fundamental na legitimação de ideias e obras literárias, além de discursos que atendiam interesses político-culturais.
Revolutionizing Drug Development: Harnessing the Potential of Organ-on-Chip Technology for Disease Modeling and Drug Discovery
Authors: Zeb Jehan 
Published: February 2025

One of the groundbreaking advancements in the field of biomedical research is the development of organoids or organ on chip technology. Promising potential of this technology has reshaped the future of disease modelling and drug discovery. Organoids are microfluidic devices which can mimic the physiological functions of natural organs of human body. Animal models are being used in laboratories to evaluate the drug effectiveness but due to the recent ethical concerns, regarding the use of animals, are affecting drug development and treatment for various diseases. But organ on chip is an emerging tool which is filling the gap between animal models and outcomes of drug treatment by eliminating the ethical concerns.
Demand for precision medicine is growing due to rapid arousal of various deadly disease but traditional methods of developing drugs fall short as they can’t exactly replicate the human physiology. So instead of using animal models or cell cultures to design drug, to detect the its efficacy and toxicity, organ on chip technology is perceived to be a best option. It saves the time and resources that were being wasted, due the use of animal models, during the preclinical and clinical trials of the drug. On the other hand, organoids are more reliable in satisfying the demand of precision medicine. These artificial organs provide a bioengineered platforms mimicking the specific functions of living organs such as gut peristalsis and lung breathing in a very controlled manner. Moreover, different organs communication after drug treatment is also being studied by developing multi-organ systems so that the utility of these micro-engineered organs can be enhanced. These organs generate more accurate data about the drug effectiveness and toxicity. Moreover, it generates it in real time thus reducing the reliance on the animal models on which testing is usually time taking and can give false results. Furthermore, molecular basis of numerous complex diseases like cancer, diabetes and neurogenerative diseases can be predicted with this technology and it is very helpful in producing precision medicine. Controlled drug delivery is one of the best applications of these organoids eliminating the chance of false hits. Therefore, this technology has demonstrated a paradigm shift in biomedical research providing a better alternative in case of efficiency and reliability.
Now the integration biosensors, artificial intelligence in organ on chip technology has enhanced its predictivity power and also allow the real time imaging and monitoring of cellular responses to the particular drug. Though, there some obstacles regarding the adoption of this technology but efforts are being made continuously to accelerate its usage in mainstream research. Thus, paving the way for a new era of personalized medicine.
García Canclini como editor extraño
Authors: Lèal Alfredo 
Published: February 2025

Conocido, sobre todo, por su reelaboración del concepto de hibridez para el estudio de las producciones culturales latinoamericanas, la obra del antropólogo argentino Néstor García Canclini, exiliado en México a causa de la última dictadura militar, no estaría completa si olvidáramos considerar la labor que realizó, diseñando estrategias, recuperando textos y reuniendo a autorxs en cuadernos y series —siendo la más importante la Serie Culturas, de Gedisa—, en su faceta de editor. Dicho trabajo bien pudo haber pasado inadvertido a no ser porque, a inicios del siglo XXI, García Canclini daría un giro a su escritura, recuperando un estilo autoficcional al que fue muy próximo en sus años de formación en Paris-X, donde Paul Ricœur dirige su tesis doctoral. Con base en dos textos clave para entender el modo en que García Canclini se autorepresenta —“Desencuentros entre un antropólogo latinoamericano, un sociólogo europeo y una especialista en estudios culturales estadounidense” (1999) y “Lectores póstumos” (2018)—, este trabajo estudio el texto “Por qué existe literatura y no más bien nada” (2014) como manifiesto de la poética de editor de Canclini.

Authors: Gaddam Ramani , Kothalanka Amarendra 
Published: February 2025

Objective: A Vehicular Ad-Hoc Network (VANET) is one of the crucial elements of an Intelligent Transport System (ITS) and plays a significant role in security and communication. VANETs are susceptible to Denial of Service (DoS) attacks, which are an inherent threat to the security and performance of such networks, requiring more sophisticated detection and countermeasures. Methods: In response to this problem, the Spatial Hyena Security Transformer Model (SHSTM) is introduced to improve the security and use of Vehicular Ad-hoc Network (VANET) communication against DoS attacks. The network nodes are set up to enable Vehicle-to-Vehicle (V2V) communication; the SHSTM constantly detects each node to detect and filter out DoS attack targets. The model includes an effective Cluster Head (CH) selection approach based on traffic patterns to enhance network security.Results: Comparative performance measurements conducted based on network positions before and after the attacks show enhanced overall performance in terms of Packet Delivery Ratio (PDR), Network Throughput (NT), Energy Consumption (EC), End-to-End Delay (EED), and Attack Detection Ratio (ADR). The network attains an NT of 3.91 Mbps, minimal EC of 1.02 mJ, highest PDR of 99.04%, minimal EED of 0.0206 seconds, and higher ADR of 98%. Conclusions: The design of the proposed SHSTM proved a significant improvement in security and network performance, which outperforms the existing state-of-the-art technique. Hence, it is considered a potential solution to address the DoS threat in VANET.
