Gerontosociology

Advancing Gerontological Insights for a Healthier Tomorrow

Welcome, My Dear Visitor!

As a PhD student at Semmelweis University, my research focuses on the health-related attitudes, decisions, and health behaviors of the ageing population, with particular attention to the social and organizational dimensions of primary prevention. I created this website to provide a comprehensive overview of my research activities and their different directions.

On this site, I present the role and accessibility of Health Development Offices (HDOs), as well as their impact on the health behavior of older adults and the factors that influence the acceptance or rejection of preventive health services.

Another, methodologically oriented line of my research addresses the analysis of uncertainty and patterns underlying empirical data. Within this framework, I am developing and applying a novel metric, the Imprecision Entropy Indicator (IEI), which enables the quantitative assessment of informational uncertainty, concentration, and the structural characteristics of data patterns. This approach is applicable not only in the social sciences, but also in health sciences and decision-support contexts.

Uncertainty can be understood as the maximum amount of information carried by a given data pattern. The two- and three-dimensional spatial arrangement of data provides an information structure that can be analyzed through uncertainty per unit of concentration using the IEI indicator. When this measure is combined with average distance and directional components, it yields an entropy field, the analysis of which allows for a deeper understanding of the observed phenomenon.

The aim of this website is to present these conceptually distinct yet interrelated research directions within a unified interdisciplinary framework.

Thank you for visiting in my hompage and I look forward to collaborating with you to improve the health and well-being of our ageing population.

  • Where Did the Story Begin?

    A long time ago in 2005 when I graduated from the University of Pécs, Faculty of Health Sciences, specialising in Health Insurance and worked as a teaching assistant lecturer at the University of Pécs between 2005 and 2011. During this period, my teaching primarily focused on health financing and informatics, alongside statistics. The following milestone…
