This study examines migration as a key factor influencing the demographic security and national resilience of the Republic of Bulgaria. The research explores migration processes in both their internal and international dimensions, together with the principal theoretical approaches explaining migration dynamics and their demographic implications. Particular attention is paid to the risks associated with population decline, labor shortages, population aging, and regional demographic disparities, as well as to the potential of migration to serve as a strategic resource for sustainable national development. The study applies a qualitative and comparative analytical approach based on statistical, documentary, and policy data for the period 2019-2024. Based on the conducted analysis and selected international experience, conclusions and recommendations are formulated for the development of an integrated migration policy aligned with Bulgaria’s demographic and national security priorities.
Introduction Eradication of human papillomavirus (HPV) is a global public health priority. It is linked to approximately 5% of all cancers, causing almost all cases of cervical cancer, nearly 90% of anal cancers and a significant proportion of oropharyngeal, penile, vaginal and vulval cancers. HPV vaccination can provide protection when 90% coverage is reached. However, many countries are yet to achieve this threshold. Uptake in Romania, Bulgaria and Croatia has been low historically, and although rates are increasing, vaccine coverage remains significantly lower than the recommended WHO rate of 90%. This systematic review sought to identify the barriers and enablers to HPV vaccine uptake in these three countries. Methods The Joanna Briggs Institute (JBI) convergent integrated methodological framework for mixed methods systematic reviews was employed. Seven databases were searched from inception to April 2024. No restrictions were imposed on language or setting. All included studies were critically appraised with JBI Critical Appraisal tools. Data extraction was performed using standardised tools with an emphasis on equity, followed by data transformation and data synthesis. Each stage was conducted by two independent reviewers. Bronfenbrenner’s socio-ecological model was applied as a theoretical lens. Results A total of 402 findings from 31 studies were extracted and aggregated to form 65 categories. These were further combined in a meta-synthesis which yielded 13 synthesised findings. The meta synthesis identified commonalities across each country’s findings: attitudes towards HPV vaccination were characterised by distrust and misconceptions; knowledge deficits existed particularly in relation to gender neutral provision; and a lack of consensus among health professionals concerning the efficacy and safety of the vaccine impacted intention and uptake. Conclusions Barriers and enablers to HPV vaccine uptake centred on knowledge and trust. Public health interventions that address the concerns of young people, parents and health professionals are pivotal to improving HPV vaccine coverage across the three countries. Contemporaneous research to further explore the social, cultural and political factors that impede acceptance of the HPV vaccine is also required. PROSPERO registration number CRD42024523200.
Modern network analysis places demands on tools that transform raw packet captures into actionable intelligence with minimal manual effort. The algorithm in this paper rises to this challenge through its innovative dual engine approach, combining the efficiency of dpkt for packet parsing with PyShark’s depth for DNS analysis. The tool automatically classifies 21 application protocols, maps traffic geolocations via GeoIP2, and distinguishes intranet, VPN, and internet communications—all while generating structured Excel reports. Unlike conventional analyzers, it detects protocols through both port and payload inspection, revealing hidden traffic patterns. This solution reduces the time for analysing the raw data and the focus goes to the already filtered data.
Chemical weapons, designed for mass harm, are posing risks of contamination, accidents, and ecological damage, and thus require their destruction. However, destruction of chemical weapons is challenging, notably in the Russian Federation due to the large scale and complexity of chemical weapons stockpiles, the diverse toxic agents stored under varying conditions, logistical and political obstacles, financial constraints, and the disposal process. Here we review the Russian Federation’s chemical weapons disposal program with an emphasis on the political context, declared chemical weapons stockpiles, methods for destruction, health and environmental issues, and nerve agents. We analyze stockpiles totaling nearly 40,000 tonnes of chemical agents across seven facilities, focusing on their composition, storage conditions, and destruction technologies. Methods such as neutralization, bituminization, and thermal destruction are compared. Environmental risks include arsenic migration and groundwater contamination near disposal sites. We observe the limitations of using bitumen salt masses as a safe disposal method.
A brief overview and analysis of the digital, cultural, and strategic transformation and the relationship between each transformation is made. A SWOT analysis is made indicating positive and negative sides and how the gaps should be corrected. The advantages of each transformation, the method of implementation, and the role of state regulation in implementing the transformations are examined. An algorithm for implementing each of the three transformations is indicated and how they complement each other in their implementation. The implementation of the three transformations in Bulgaria and the countries of the Balkan Peninsula is described, and good practices and weaknesses are also indicated, as well as prospects for implementation in view of the specifics of the region.
