With the exponential growth of digital media, readers face a daunting task of sifting through vast amounts of information to identify important news. This problem is especially critical for media professionals, journalists, and news agencies who need to quickly filter news articles to identify relevant and significant stories. Machine learning models offer a promising solution by automatically classifying news articles based on their significance. In this paper, we propose novel machine learning models for news significance detection, leveraging state-of-the-art deep learning architectures and a dataset of news articles. We evaluate our models using a variety of performance metrics and demonstrate their effectiveness compared to existing methods. Our proposed approach has the potential to significantly improve the efficiency and accuracy of news selection, benefiting both media professionals and readers alike. Furthermore, it can be beneficial to forecast the popularity of fake news and prevent its dissemination in society. Approximately, 2800 Azerbaijani news articles have been collected from telegram and labeled as popular or unpopular according to statistical calculation results. For news popularity detection, application of SVM, Random Forest and Neural network models and their results have been discussed in this paper.

Author(s): Dorina-Luminiţa COPACI,Constantin-Alexandru COPACI / Language(s): English Publication Year: 0

Virtualization is a type of process used to create a virtual environment. Many organizations think about the security implications after implementing a new technology. Virtualization can be used in many ways and requires appropriate security controls in each situation. This paper presents the idea of using a virtual machine to share services and information over the Internet. In case of an attack, the resources of the virtual machine will be affected, while the resources of the real machine are safe. In this paper, we present the perspective of an attack by running malicious software on a virtual machine. We will show that although unauthorized control of the virtual machine is obtained, the real machine is not affected.

A Signal Theory Model for Security Monitoring using CheckMK

Author(s): Iliuță-Alexandru IONEL / Language(s): English Publication Year: 0

Continuous monitoring of intelligent systems is used to analyze data and text from various sources. They usually monitor things such as risk, controls, opportunities, competition, and other concerns. While there exists literature that provides information on the capabilities of this kind of system, there has been a limited theoretical development in this field. The information sources monitored by these systems provide signals related to events, activities, or issues. However, selecting the appropriate information sources is not a simple task, because it is influenced by factors such as time, cost, redundancy, reliability, or weak signals. Furthermore, for the monitored signals, it is recommended to generate some analytics to study the flow and have a traceability of the issue we are dealing with. In this paper, a signal theory model is introduced and applied to address some of these issues regarding the SSH brute-force attacks. I will use a tool called CheckMK and its capabilities to implement a signal theory model used for monitoring security of a system.

Author(s): Ruxandra RÎMNICEANU / Language(s): English Publication Year: 0

The actual "permacrisis" marks the five transitions that are unfolding simultaneously: a transition in the planet's climate regime, an energy transition, a geopolitical transition, a technological transition and a demographic transition. In this context, all the risks that are around show us that we are dealing with a programmed chaos that might affect the financial ecosystem, also. In this respect, such to avoid a collapse and to strengthen the banking and financial sector, the European entities appreciate that there it is necessary to strengthen the leadership of the EU in the digital domain by promoting inclusive and sustainable digital policies, serving citizens and businesses. Taking into account that the risks of increased exposure to potential cybercrime, operational resilience failures and data protection and privacy issues could have an important impact, the digital transformation must be in line with EU values - the 2030 policy program entitled "The Path to the Digital Decade" and "The Declaration on Digital Rights and Principles in the E.U.".

RECENT AND FUTURE TRENDS IN SUSTAINABILITY REPORTING

Author(s): Eleonora Petrova Stancheva-Todorova / Language(s): English Publication Year: 0

Few non-mandatory standards on sustainability reporting have been developed in the last two decades as a result of few global initiatives, including the Global Reporting Initiative, the International Integrated Reporting Council, the Taskforce for Climate- Related Financial Disclosures, etc. In April 2021, the European Union updated its Non- Financial Reporting Directive. Moreover, the World Economic Forum issued its new standards on common metrics and consistent reporting for sustainable value creation. These and few other initiatives and standards currently shape the sustainability reporting landscape. But the need for harmonization of non-financial reporting is on its way to change it. The lack of one single global set of standards is challenging the standard setters, policymakers, and other stakeholders and some have already started to cooperate. In early November 2021, the International Financial Reporting Standards (IFRS) Foundation Trustees announced the establishment of a new standard-setting board – the International Sustainability Standards Board, to meet the demand of high quality, transparent, reliable, and comparable reporting by companies on climate and other environment, social and governance (ESG) matters. Inspired by the urgency of more holistic and comprehensive corporate reporting encompassing company’s ESG metrics and disclosures, this paper aims at collecting discussions on the future of sustainability reporting through the lens of the recently identified trends in its development.

The rapid growth of international production until about 2010 was driven by the underlying economics, the supportive policy environment, and enabling technological developments. Changes in direction in the same three factors caused the stagnation in international production in the 2010s. Looking ahead, the trio of technology, policy and economic considerations continues to be a helpful guide to structure the analysis of expected trends. Only the relative importance of the factors, their intensity and their detailed composition is likely to change. However, all three have arrived at critical inflection points that could fundamentally alter the configuration of international production over the next decade.

The peculiarity of wind generators as an object of evaluation is that they are a complex system - equipment that has separate elements that can be subject to self- assessment, as well as the fact that the wind generator that produces electricity together with service equipment can be considered and evaluates as a business, through the approaches and methods used in the valuation of commercial enterprises. The second important feature is that the installed and operated wind generator are permanently connected to the ground through their foundations and are essentially immovable facilities. The necessary documents under the Spatial Development Act are being developed for it and construction and installation activities are being carried out. Therefore, in their assessment as an active object, two appraisal competencies are required - an independent real estate appraiser and an independent appraiser of machinery and equipment. When evaluating a wind generator or wind farm, an independent appraiser of commercial enterprises and receivables may be involved as an independent business.

Although developments in economics, science, and technology have influenced the field of education, the belief in the individual and societal benefits of education has remained unchanged. The determination of the benefits of education revolves around debates on whether education serves as an economic function and whether it is a consumption and/or investment good. Considering that the primary aim of education is to nurture individuals, the qualities of the individuals to be cultivated will turn them into producers and consumers under the influence of the economy. To determine the individual and societal benefits of education, the private and social returns of education are calculated. In this section, the costs, benefits, returns, and cost-benefit ratios of public/private education in Turkey are discussed.
