Abstract

The advancement of telemedicine and robotic surgery has led to increased interest in haptic feedback systems, which enhance the surgeon's ability to perform remote procedures. Haptic technology provides tactile sensations, allowing surgeons to feel the instruments' interactions with tissues, thus improving precision and control during surgery. This research aims to implement haptic feedback in robotic surgical systems, evaluating its impact on surgical performance and user experience during remote operations. The study seeks to determine whether incorporating haptic feedback can enhance the effectiveness and safety of robotic-assisted surgeries. A mixed-methods approach was employed, combining hardware development of a robotic surgical system with haptic feedback integration. Surgeons participated in controlled experiments to perform simulated surgical tasks with and without haptic feedback. Performance metrics, including task completion time, accuracy, and user satisfaction, were assessed. The implementation of haptic feedback resulted in a 30% reduction in task completion time and a 25% improvement in accuracy compared to non-haptic conditions. Surgeons reported higher satisfaction levels and increased confidence in performing procedures with the haptic-enabled system. The findings indicate that integrating haptic feedback into robotic surgical systems significantly enhances surgical performance and user experience. This research contributes to the growing body of knowledge in robotic surgery, demonstrating the potential of haptic technology to improve outcomes in remote surgical procedures.

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

The emergence of generative artificial intelligence (AI) has redefined the boundaries between artistic creation and computational design, prompting critical debates on the evolving nature of human creativity. The rapid advancement of AI tools capable of producing visual art, music, and literature challenges traditional notions of authorship, originality, and aesthetic value. This study aims to explore the intersection of art and technology by examining how generative AI transforms creative processes and influences artistic identity. A qualitative research design employing case studies and thematic analysis was utilized to investigate the experiences of 15 artists and designers who integrate AI-based tools, such as DALL·E, Midjourney, and ChatGPT, into their creative workflows. Data were collected through in-depth interviews, artifact analysis, and digital ethnography. The findings reveal that generative AI functions as both a collaborator and a disruptor expanding creative possibilities while raising ethical and philosophical questions about human agency in artmaking. Participants reported enhanced productivity, conceptual exploration, and aesthetic experimentation, yet also expressed concerns about the loss of emotional authenticity and authorship. The study concludes that generative AI represents a paradigm shift toward co-creative art, necessitating new frameworks for understanding creativity, ethics, and digital aesthetics in the post-human era.

Abstract

The exponential escalation of computational density required by modern Artificial Intelligence (AI) and Large Language Models has pushed traditional air-cooled data center infrastructures to their thermodynamic limits. This study investigates the efficacy of single-phase liquid immersion cooling as a transformative solution to manage the extreme thermal flux of next-generation AI accelerators. Adopting a quantitative experimental design, we benchmarked a high-density GPU cluster submerged in a proprietary dielectric fluid against a standard forced-air baseline under intensive MLPerf training workloads. The research focused on evaluating key performance indicators, including Power Usage Effectiveness (PUE), processor junction temperatures, and total energy consumption over a 168-hour stress test. Results demonstrate that the immersion architecture achieved a near-ideal PUE of 1.04, representing a 34% efficiency improvement over the air-cooled control group. Furthermore, the liquid medium maintained GPU core temperatures 20°C lower than the baseline, effectively eliminating thermal throttling events and enhancing computational stability. The study concludes that shifting from aerodynamic to hydrodynamic cooling is not merely an efficiency upgrade but a physical prerequisite for the sustainable scaling of exascale AI infrastructure, offering a viable pathway to decarbonize the expanding digital economy.

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

Abstract

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.

Abstract

Background. This study examines posthumanist themes and ecological consciousness in the science fiction works of Dewi “Dee” Lestari, one of Indonesia’s most influential contemporary authors whose narratives frequently challenge anthropocentric worldviews. The background of this research lies in the growing global interest in posthumanist discourse, which critiques human-centered epistemologies and emphasizes the entanglement of humans, technology, and the natural environment. Purpose. The aim of this study is to analyze the narrative strategies, philosophical motifs, and ecological representations through which Dee constructs a posthumanist imaginary that destabilizes traditional boundaries between human and non-human agents. Method. The study employs a qualitative textual analysis method grounded in literary ecocriticism and posthumanist theory, drawing on close reading techniques and thematic mapping. Results. The results reveal that Dee’s narratives articulate a model of relational existence in which technology, consciousness, and ecological systems are interdependent rather than hierarchically ordered. Her work foregrounds ethical responsibility, cosmological humility, and the dissolution of rigid subject-object distinctions, offering a vision of scientific and spiritual evolution embedded within ecological awareness.   Conclusion. The study concludes that Dee’s science fiction significantly contributes to Indonesian literature by integrating posthumanist philosophy with ecological sensibility, encouraging readers to rethink the role of humans within a broader planetary network. This research highlights the relevance of Indonesian speculative fiction to global debates on ecological crisis and posthuman futures.
