Abstract

The increasing use of social media has raised concerns about its psychological impact on young adolescents, particularly concerning their self-esteem and body image. This study explores the effects of social media engagement on the self-esteem and body image perceptions of pre-adolescent students aged 10-12 years. The research aimed to assess how the frequency and nature of social media use contribute to body dissatisfaction and self-esteem levels among pre-adolescents. A mixed-method approach was employed, using surveys and in-depth interviews with 200 pre-adolescent students from four schools. The quantitative data were analyzed through descriptive statistics and correlation analysis, while qualitative data were thematically analyzed to gain deeper insights into personal experiences. The results indicated a significant negative correlation between social media usage and self-esteem, with increased exposure to idealized body images linked to higher levels of body dissatisfaction. Moreover, participants reported feeling pressure to conform to social media beauty standards, which impacted their body image perceptions. In conclusion, the findings highlight the importance of managing social media exposure for young adolescents to mitigate its potential negative effects on self-esteem and body image. Educational and parental interventions are essential to support pre-adolescents in developing healthier social media habits.

Abstract

The coupling of superconducting qubits with spin ensembles has emerged as a promising solution to bridge the microwave-optical frequency gap in hybrid quantum systems. These systems are crucial for advancing quantum communication, quantum networks, and integrated quantum technologies. However, achieving coherent coupling between these two platforms remains a significant challenge due to the differences in their operational frequency regimes and their susceptibility to decoherence. This research aims to explore the coherent coupling between a superconducting qubit and a spin ensemble, specifically focusing on its potential for efficient microwave-to-optical transduction. The primary objective of this study is to develop a hybrid quantum system that enables the transfer of quantum information between microwave and optical domains with minimal loss of coherence. Experimental and theoretical approaches were used, involving superconducting qubits and nitrogen-vacancy (NV) centers in diamonds as the spin ensemble. The results demonstrate that the coupling mechanism is efficient, achieving high transduction efficiencies and long coherence times, particularly at optimized coupling strengths. These findings suggest that the hybrid system can be used for scalable quantum communication systems, facilitating quantum information transfer across different frequency domains. In conclusion, this study provides a robust method for microwave-to-optical transduction, opening new avenues for quantum network development and hybrid quantum technologies.

Abstract

Border areas face increasingly complex security challenges that cannot be effectively addressed through state-centric approaches alone, highlighting the need for inclusive strategies that incorporate local communities. Civil participation plays a critical role in enhancing situational awareness, early threat detection, and collaborative security practices. This study aims to examine the role of community-based territorial defense in strengthening civil participation and improving national security outcomes in border areas. A mixed-methods design was employed, combining quantitative survey data from 200 border residents with qualitative insights from community leaders and security personnel. Data were analyzed using descriptive and inferential statistics alongside thematic analysis to capture both measurable trends and contextual dynamics. Findings indicate that active community participation significantly correlates with improved perceived security, reduced localized threats, and enhanced coordination with security institutions. Institutional trust and access to training emerge as key predictors of participation, while social cohesion strengthens sustained engagement. The study concludes that community-based territorial defense provides an effective and context-sensitive framework for enhancing national security by integrating local knowledge, institutional support, and participatory governance. Sustainable implementation requires structured programs, trust-building mechanisms, and alignment with socio-cultural conditions in border regions.

Abstract

This study examines the application of Internet of Things (IoT) technology in modern livestock management in New Zealand. The background of this research is based on the need to increase productivity, efficiency, and sustainability in the increasingly competitive livestock sector. The purpose of the study is to explore the benefits of applying IoT in livestock health monitoring, feed management, as well as the impact of this technology on the environment and sustainability. The research method used is descriptive-qualitative with data collection through interviews, field observations, and secondary data analysis. The results show that the adoption of IoT in large farms increases productivity by up to 20% and reduces operational costs through more efficient feed management. The study also found that infrastructure challenges are a hindrance to IoT adoption in small and medium-sized farms. The conclusion of the study is that IoT has the potential to be a key solution to improve efficiency and sustainability in the livestock sector, but infrastructure support and training are urgently needed to accelerate its adoption across sectors.

Abstract

The pervasive environmental pollution caused by petroleum-based plastics has catalyzed the search for sustainable alternatives. Bioplastics, derived from renewable biomass, offer a promising solution, yet their production can be inefficient and compete with food resources. Synthetic biology provides powerful tools to engineer microorganisms for the high-yield production of bioplastics like polyhydroxyalkanoates (PHA) from non-food feedstocks. This study aimed to conduct a comprehensive life cycle assessment (LCA) to quantify and compare the environmental impacts of PHA produced via a synthetically engineered microbial platform against conventional polyethylene terephthalate (PET). A "cradle-to-grave" LCA methodology was employed, encompassing feedstock cultivation, fermentation, polymer extraction, and end-of-life scenarios including landfilling and industrial composting. The results revealed that the synthetic biology-driven PHA exhibited a 65% lower global warming potential and a 70% reduction in non-renewable energy use compared to PET. However, it showed higher impacts in eutrophication and land use, linked to its lignocellulosic feedstock origins. The end-of-life analysis confirmed the significant advantage of PHA’s biodegradability. This study concludes that while synthetic biology-driven bioplastics offer substantial benefits in carbon footprint and fossil fuel dependency, a holistic view is crucial.
