Clustering is a complex data mining tool, useful to identify similarities in large amount of data, the medical databases being highly suitable in this regard. Our paper aims to compare the efficacy of two well-known clustering methods, the n-means algorithm and the classical hierarchical algorithm, and to apply them in analyzing a medical-economic database on dietary habits, social economic status and oral health in a sample of 326 men, aged between 25 and 30, living in the urban area – in order to identify possible associations between dietary habits and income levels. We identified 4 clusters which correspond partially to the 4 income levels recorded in the investigated sample and reveal the associated dietary habits. The n-means clustering performed better than the Single Linkage hierarchical classification, being therefore highly suitable in the analysis of socio-economic and general health data.

Greece has rebounded from the COVID-19 crisis, generating strong employment growth. Government support measures, implementation of the Greece 2.0 Recovery and Resilience Package and the reforms of the past decade have been supporting the economy. However, headwinds from surging energy prices and uncertainty following Russia's war of aggression against Ukraine have slowed the recovery. Returning the budget to surplus, better targeting energy support measures and maintaining government revenues while broadening the tax base and improving its efficiency will help sustain the recovery and Greece's prospects of achieving an investment-grade sovereign debt rating. Maintaining the reform momentum, prioritising banks' health and addressing the long-standing barriers to private investment, can help maintain this momentum into the long term. This would also support Greece in contributing its share to address climate change, by achieving net zero emissions, while raising living standards. The changing climate is already disrupting livelihoods and well-being in Greece. A well-chosen mix of carbon pricing, public infrastructure investments, raising buildings' energy efficiency and moving transport into low-emission modes can achieve emission cuts cost-effectively, while making people better off with improved housing quality and mobility. Engaging all stakeholders, maintaining a consensus and supporting vulnerable households affected by the green economy transition will help ensure progress continues into the longer term.

"The Efficiency of Qualitative Data Clustering in Medical and Socio-Economic Surveys - Comparative Study" is an article that explores the use of clustering methods in analyzing medical and socio-economic data. The study compares the effectiveness of two clustering algorithms, the n-means algorithm and the classical hierarchical algorithm, in analyzing a database on dietary habits, socio-economic status, and oral health in a sample of men aged 25 to 30. The results indicate that the n-means clustering method outperformed the hierarchical classification method, making it suitable for analyzing socio-economic and general health data. The article also discusses the attributes of the two clustering algorithms and their application to real data, highlighting the advantages of certain methods for accurate analysis. Additionally, the article discusses the classification of data related to dietary habits and income levels, revealing correlations between income levels and dietary habits. The document suggests that further analysis of these associations can provide insights into the psychological, medical, and sociological reasons behind dietary habits. [Extracted from the article]

The subjects of the study are private security companies. Its object is the leading role of the customer-centric approach for financial and economic justification of the successful functioning and development of private security companies. The research hypothesis is that an objective assessment of the financial and economic aspects and the motivation of individuals and legal entities to purchase protection and security services under the conditions of post-epidemic recovery of the economy can be carried out by means of customer satisfaction and service pricing justification surveys. The aim of this article is to present the results of a customer satisfaction survey and the assessment of the financial and economic aspects as well as the motivation of individuals and legal entities to purchase protection and security services under the conditions of post-epidemic recovery of the economy. Structurally, the article includes three main sections: the first section focuses on the circulation of cash flows of private security companies; the second section presents selected elements of the conducted survey; and the third present an analysis of the survey among private security companies where the protection and security services compete and at the same time complement property insurance services. The survey results (based on a multi-crtieria Likert scale) confirm the validity of the "value for money" concept as an important factor for the pricing of private protection and security services. The survey questionnaire successfully compares the services of non-life insurance companies and the services of protection and security companies. The prevailing opinion is in favour of using the services of specialized companies over taking out insurance policies, with 61% of respondents expressing the opinion that hiring a specialized protection and security company is a more effective way to ensure property protection to taking out equivalent insurance with a general insurance company.
