Abstract

In this work, a novel poly(methyl methacrylate) (PMMA) material was prepared by incorporating Schiff base and metal oxide nanoparticles (NPs). Hence, different polymer derivatives were produced, and their resistance to light degradation was improved. PMMA was subjected to chemical modification, first by reacting PMMA with an excess of ethylene diamine to reduce the occurrence of cross-linking. Second, it underwent a reaction with the amino group of 4-methoxybenzaldehyde to produce Schiff base molecules. These molecules were subsequently infused with various metal oxide NPs, namely: TiO2, CuO, Cr2O3, Co2O3, and NiO to work as photostabilizers and prepare modified PMMA films. The synthesized polymers were analyzed using Fourier transform infrared (FTIR) and NMR spectroscopy to confirm their structures and determine the extent of structural alterations. FTIR and weight loss measurements assessed modified PMMA's UV stabilization. The effectiveness of functional groups was assessed by monitoring their growth. Additional analyses were done included atomic force microscopy (AFM), scanning electron microscopy (SEM), and microscopic imaging. Unmodified PMMA performed worse than Schiff base polymers. The modified PMMA photodegraded less than the blank films after 300 h of UV exposure. The unit's strong internal conjugation absorbs UV light, which improves performance.

Abstract

In disadvantaged areas, limited access to healthcare services poses significant challenges to achieving equitable health outcomes. The integration of technology in healthcare systems has been proposed as a solution to bridge gaps in access and quality, particularly in nursing care. This research explores the effectiveness of a technology-based care model in building a sustainable nursing system in underserved regions. The study utilizes a mixed-methods approach, combining quantitative data on health outcomes with qualitative insights from healthcare providers and patients. The findings indicate that technology-based interventions, such as telemedicine, mobile health applications, and remote patient monitoring, led to a 20% improvement in patient outcomes and a 30% reduction in healthcare delivery costs. Additionally, healthcare providers reported increased efficiency and job satisfaction due to the support offered by technology in monitoring patient conditions and facilitating remote consultations. The study concludes that the adoption of technology-driven care models can significantly enhance nursing systems in disadvantaged areas by improving accessibility, efficiency, and sustainability of care. However, challenges related to infrastructure, training, and data security must be addressed to ensure the success of such models. Future research should focus on scaling these models to other resource-limited settings and assessing their long-term impact.

Abstract

This paper draws attention to a recently identified sub-variant of SARS-CoV-2 known as EG 5, colloquially named "Eris," designated by the World Health Organization (WHO) as a variant of interest. The organization has urged nations to monitor and respond to the spread of this sub-variant since its identification on February 17, 2023. The discovery of the EG 5 variant, a sublineage of the Omicron variant, has introduced new challenges. Designated a "variant of interest" by the WHO, EG 5 carries distinctive genetic mutations, including an additional F456L amino acid mutation in the spike protein. Global prevalence has doubled, raising concerns about increased transmissibility. Although specific symptoms of EG 5 are not yet fully characterized, the variant has spread to 51 countries, with over 7,000 reported cases by August 15, 2023. The manuscript also explores the unique situation in Iraq, where, as of August 17, 2023, no EG 5 cases have been officially recorded. However, challenges such as self-treatment at. As the world grapples with the ongoing challenges of the COVID-19 pandemic, understanding the dynamics of emerging variants is crucial for effective public health responses and the development of targeted interventions.

Abstract

The increasing presence of Islam in Europe has led to the emergence of modern mosque architecture, raising questions about its impact on Islamic identity. This study examines how modern architectural styles influence the perception and experience of Islamic identity within European Muslim communities. This research aims to analyze the architectural features of selected modern mosques in Europe and explore how these features interact with the construction and negotiation of Islamic identity among worshippers. Employing a qualitative research methodology, this study conducts case studies of several prominent modern mosques in various European countries. Data collection involves site visits, architectural analysis, and semi-structured interviews with mosque attendees and community leaders. The study analyzes the interplay between modern architectural aesthetics, traditional Islamic architectural elements, and the evolving interpretations of Islamic identity in a European context. Some mosques prioritize minimalist designs and contemporary materials, while others incorporate subtle Islamic motifs within modern frameworks. The study concludes that modern mosque architecture in Europe serves as a dynamic space where Islamic identity is negotiated and expressed in diverse ways, reflecting the complex interplay between tradition, modernity, and the specific socio-cultural contexts of European Muslim communities.

Abstract

Psychological well-being is a critical factor influencing overall mental health, yet traditional counseling approaches may not fully address the diverse needs of clients. Art therapy, as a creative and expressive intervention, has gained recognition for its potential to enhance psychological well-being through non-verbal and experiential processes. This study investigates the influence of art therapy in counseling and its effectiveness in promoting psychological well-being. The research aimed to evaluate the impact of art therapy on emotional regulation, self-awareness, and stress reduction among individuals seeking counseling services. A mixed-methods design was employed, combining quantitative and qualitative approaches. A total of 80 participants were divided into intervention and control groups, with the intervention group attending a 10-week art therapy program integrated into their counseling sessions. Data were collected through standardized psychological well-being scales and semi-structured interviews. Results indicated significant improvements in psychological well-being scores for the intervention group compared to the control group (p < 0.01). Participants reported increased emotional expression, enhanced coping mechanisms, and a stronger sense of self-awareness. Qualitative data supported these findings, highlighting art therapy’s role in fostering a safe and reflective space for personal growth. The study concludes that art therapy is an effective complementary approach in counseling, offering valuable benefits for enhancing psychological well-being. These findings underscore the importance of integrating creative methods into therapeutic practices.
