QREAM: QR-code Emergency Assistant Model

/in /by

Using a Quick Response (QR) code has been spread over most applications, such as registration, commercial, and verification purposes. Emergency situations need a quick and effective action plan including communication, identification, and full data access to provide urgent assistant. In Saudi Arabia, the Hajj event similar cases might occur. As a result of that, a quick response plan is needed to provide assistant in emergency situations for pilgrims.

The aim of this paper is to introduce and to describe an emergency assistant model based on using QR-Code (QREAM). In addition, this paper will discuss the model design and analyse the results of using the QREAM.

Core-Tax System Implementation and Tax Revenue in Indonesia and OECD Countries: A Systematic Literature Review

/in /by

The implementation of core-tax systems represents a transformative step in modernizing tax administration, offering the potential to enhance efficiency, compliance, and revenue generation. This systematic literature review examines the relationship between core-tax system implementation and tax revenue, with a particular focus on Indonesia and comparisons with OECD countries. Drawing from studies published between 2011 and 2024, the review synthesizes insights on the benefits, challenges, and impacts of these systems across different economic and technological contexts. Key findings highlight that digital tax systems improve administrative efficiency, reduce compliance costs, and foster greater transparency. However, challenges such as infrastructure deficits, taxpayer resistance, and regulatory complexity persist, particularly in developing countries like Indonesia. By contrast, OECD countries benefit from advanced infrastructure, streamlined regulations, and higher taxpayer trust, providing valuable lessons for nations transitioning to digital systems. In Indonesia, initiatives such as the Core Tax Administration System (CTAS) have shown promise in addressing compliance gaps and increasing revenue collection. Nevertheless, significant barriers remain, including uneven internet access, low digital literacy, and cultural resistance to digital adoption. Comparative analysis underscores the importance of targeted investments in infrastructure, simplification of tax procedures, and fostering trust through transparent practices. This review identifies gaps in the literature, such as the long-term impact of core-tax systems on economic growth and fiscal stability, and calls for future research to explore these dimensions. Policymakers are urged to adopt a holistic approach that integrates technological advancements with robust policy frameworks and taxpayer engagement. By addressing these challenges, countries can leverage core-tax systems to enhance governance, strengthen public finances, and drive sustainable economic development. This study contributes to the growing body of knowledge on tax modernization and its critical role in shaping equitable and efficient fiscal systems.

The Working Mechanism of the Brain in Maintaining Physical, Psychological, And Spiritual Balance Through Emotional Management: Systematic Literature Review

/in /by

This study is a systematic literature review that aims to explore the working mechanisms of the brain in maintaining physical, psychological, and spiritual balance through emotional management . Using the PRISMA approach, this study interpreted 108 relevant journals, then conducted an in-depth review of 16 selected literatures from national and international sources (2015–2025). The results of this review include the working mechanisms of the brain in regulating cognitive, emotional, and behavioral functions, as well as physiological responses that activated by the HPA axis through emotional management . In addition, the Islamic spiritual approach—with the implementation of prayer practices, dhikr, and reading the Qur’an—is described as an effective stress management strategy through reducing physiological stress and improving mental well-being. The research findings indicate that the integration of biology, psychology, and spiritual values can provide a holistic approach in dealing with emotional disorders and stress, and open up opportunities for more comprehensive interventions to restore the balance of body and soul. The implications of this study serve as a basis for developing intervention therapies that combine scientific and spiritual aspects to improve the quality of mental health amidst the pressures of modern life.

Genetic Insights into Oligodontia: A Comprehensive Review of Mutations in Key Genes and Their Implications for Tooth Development

/in /by

Introduction:  Tooth agenesis is one of the most frequent congenital abnormalities found in the maxillofacial region. Oligodontia, a severe form of tooth agenesis, occurs as an isolated anomaly or as a syndromic feature.

Objectives:  To identify the molecular genetic etiology of multiple missing permanent teeth (oligodontia).

Discussion:  Disruptions in tooth development arise from mutations in genes like WNT10A and PAX9, where PAX9 plays a crucial role in dental epithelial cell differentiation. Additional genes, such as MSX1, AXIN2, EDA, EDAR, and EDARADD, play diverse roles in tooth agenesis. The WNT pathway, particularly the WNT/β-catenin signaling, is crucial in tooth development. Mutations in LRP6 compromise the activation of this pathway, indicating its functional significance in tooth development. Biallelic variants in POLR3GL have been associated with oligodontia, expanding the spectrum of POLR3-related disorders. Disruption of Pol III function may affect the transcription of essential RNAs involved in tooth development.

Conclusions:  Oligodontia is a genetically heterogeneous condition with a complex genetic basis involving multiple genes and pathways. Molecular analysis and genetic testing are essential for accurate diagnosis and management, contributing to our evolving understanding of the genetic causes of oligodontia.

Multi-Level Endovascular Intervention for Severe Peripheral Arterial Disease: A Case Report and Literature Review

/in /by

Peripheral arterial disease (PAD) is a progressive atherosclerotic condition that may involve multilevel arterial segments and often coexists with aneurysmal disease. We report the case of a 78-year-old male with extensive cardiovascular comorbidities who underwent staged multilevel endovascular revascularization of the tibial and femoropopliteal segments for severe PAD with concomitant aneurysmal disease. Following abnormal vascular imaging during preoperative cardiac clearance, he underwent right tibial and tibioperoneal trunk angioplasty followed by left femoral-popliteal aneurysm repair and stenting. Postoperative recovery was uneventful apart from transient acute kidney injury. This case illustrates the diagnostic and therapeutic challenges of complex PAD, highlights the evolving role of multilevel endovascular interventions, and contextualizes decision-making with current evidence and guidelines.
