Abstract

The expansion of Open Distance Learning (ODL) in recent years has highlighted the need for interactive technologies that support student engagement, knowledge retention, and personalized learning. As ODL environments often lack face-to-face interaction, interactive technologies like virtual classrooms, discussion forums, and gamified learning tools play a critical role in creating immersive learning experiences. This research aims to explore the impact of interactive technologies on student outcomes in ODL, focusing on engagement, satisfaction, and academic performance. A mixed-methods approach was used, combining quantitative surveys with qualitative interviews to capture students’ experiences with interactive tools in ODL. Data was collected from a diverse sample of students enrolled in online programs, and statistical analysis was applied to measure correlations between interactive technology usage and learning outcomes. The qualitative data provided insights into student perspectives on the benefits and challenges of using interactive tools. Findings indicate that students who actively engage with interactive technologies report higher levels of motivation and satisfaction compared to those who rely solely on traditional online resources. Interactive tools also appear to facilitate better knowledge retention and a sense of community among distance learners. However, challenges such as accessibility and technological support remain barriers to effective usage. The study concludes that interactive technologies enhance the ODL experience by promoting active learning and improving overall educational outcomes. Further research is recommended to explore scalable solutions for integrating these tools, particularly in under-resourced settings, to ensure equitable access for all students.

Abstract

Engaging urban youth in social entrepreneurship presents a significant challenge, often hindered by perceived complexity and a lack of motivational frameworks. This study investigates the potential of gamification to foster social innovation and entrepreneurial behaviors among this demographic. The primary objective was to experimentally measure the impact of a gamified intervention on the pro-social entrepreneurial intentions and idea generation quality of urban youth. This research employed a behavioral experiment with a pre-test/post-test control group design, involving 150 urban youths aged 18-24. The experimental group interacted with a gamified digital platform designed to guide them through social venture creation, incorporating points, badges, and collaborative leaderboards. In contrast, the control group used a non-gamified version of the same platform. The results revealed that participants in the gamified condition demonstrated significantly higher levels of engagement, produced more innovative and viable social solutions, and reported a greater increase in entrepreneurial self-efficacy compared to the control group. In conclusion, gamification serves as a powerful and effective strategy to lower entry barriers and motivate urban youth, channeling their creativity toward developing impactful social innovations and fostering a new generation of community-focused entrepreneurs.

Abstract

Air pollution poses a significant threat to public health, demanding effective real-time monitoring solutions. Traditional monitoring systems are often costly and sparsely located, limiting their spatial-temporal resolution. This study aimed to develop and validate a low-cost, IoT-integrated electrochemical sensor system for the real-time detection of key airborne pollutants. We fabricated electrochemical sensors for nitrogen dioxide (NO?), sulfur dioxide (SO?), and volatile organic compounds (VOCs), which were then integrated with a microcontroller and a wireless communication module. The system was calibrated and validated against reference instruments in both laboratory and field conditions. The developed sensors exhibited high sensitivity, good selectivity, and rapid response times (<60s). Field data demonstrated a strong correlation (R² > 0.92) with co-located reference-grade analyzers, and the IoT platform successfully provided continuous data visualization via a cloud dashboard. This study confirms that IoT-integrated electrochemical sensors provide a scalable and cost-effective solution for building dense, real-time air quality monitoring networks, offering significant potential for urban environmental management.

Abstract

Magnetic nanoparticles (MNPs) have emerged as promising materials for biomedical applications, particularly as contrast agents in tumor imaging. Early and accurate tumor detection is critical for improving treatment outcomes, yet current imaging techniques often lack sensitivity and specificity. This study aimed to synthesize and characterize magnetic nanoparticles for their potential as contrast agents in tumor imaging. The nanoparticles were synthesized using a co-precipitation method, followed by surface modification with organic compounds to enhance stability and targeting specificity. Characterization included transmission electron microscopy (TEM), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), and dynamic light scattering (DLS). Cytotoxicity and targeting efficiency were evaluated in vitro using cultured human tumor cells. The results demonstrated that the synthesized nanoparticles had an average size of 25 ± 5 nm, superparamagnetic properties with a saturation magnetization of 55 emu/g, and high colloidal stability due to surface modifications. Fluorescence imaging revealed significant accumulation of the nanoparticles in tumor cells, while cytotoxicity tests showed cell viability above 85% at concentrations up to 100 ?g/mL. These findings indicate the nanoparticles are safe and effective for tumor imaging. This study highlights the importance of integrating synthesis, characterization, and biological evaluation to optimize nanoparticle design for biomedical applications. While the results are promising, further in vivo studies are needed to evaluate nanoparticle distribution, accumulation, and clearance in complex biological systems. The findings provide a foundation for future research and development of advanced contrast agents for tumor imaging

Pancreatic cancer is one of the most lethal cancers with limited effective treatment options. RNA interference (RNAi) offers a promising therapeutic approach, but efficient delivery systems are essential. To evaluate the effectiveness of RNAi-based nanoparticles as a therapy for pancreatic cancer, focusing on tumor inhibition and cell viability. A comprehensive study combining in vitro, in vivo, and clinical approaches was conducted. Pancreatic cancer cell lines (PANC-1, BxPC-3, AsPC-1) and mouse models with human pancreatic tumors were treated with RNAi-based nanoparticles. Characterization of nanoparticles included size, charge, and stability assessments using DLS and HPLC. RNAi-based nanoparticles inhibited tumor growth by 70% in mouse models and reduced cell viability by 60% in vitro. Nanoparticles demonstrated high stability and effective internalization into cancer cells, leading to significant gene silencing and apoptotic effects. RNAi-based nanoparticles show significant potential as an effective therapy for pancreatic cancer, demonstrating substantial tumor inhibition and cell viability reduction.

The increasing prominence of creative entrepreneurship has been driven by shifts in consumer behavior, technological advancements, and changing work environments. Both the Millennial and Generation Z cohorts exhibit distinct entrepreneurial tendencies, shaped by different societal, technological, and economic contexts. However, there remains a gap in understanding how these generational differences impact the development of a creative entrepreneurship mindset. This study aims to compare the creative entrepreneurship mindset between Millennials and Generation Z, examining the factors that influence their entrepreneurial behaviors, decision-making, and approach to creative industries. A comparative research design was employed, utilizing both qualitative and quantitative methods. A total of 200 participants, 100 Millennials and 100 Generation Z individuals, were surveyed and interviewed. The survey focused on key entrepreneurial traits such as risk-taking, innovation, and adaptability, while the interviews provided deeper insights into their motivations, challenges, and perceptions regarding creative entrepreneurship. The findings indicate significant differences between the two generations in terms of risk tolerance, innovation, and digital fluency. Generation Z tends to exhibit higher levels of digital fluency and a preference for social media-driven entrepreneurship, while Millennials show more inclination towards traditional business models. Additionally, Generation Z shows a stronger preference for flexible, remote work environments, valuing autonomy and self-expression. The study concludes that while both generations demonstrate entrepreneurial potential, their approaches to creative entrepreneurship differ significantly. Understanding these differences can help educators, policymakers, and entrepreneurs develop tailored support programs to foster entrepreneurial growth in both generations.
