This study explores quality-of-life fundamentals, an omnipresent concept in social, medical, and other disciplines relating to human existence. High quality of life is the main premise of purposeful human activity and is deeply embedded in human consciousness. Those responsible for creating quality social life must establish suitable conditions for cultivating social capital and improving the efficiency of actions at different institutional levels by different subjects and within different local and national policies. The findings in this volume are therefore critical to those who wish to build good social relations, which are one of the most important, if not the most important, correlations to happiness.
