Abstract
The "well-being engineering" project investigates the methods to manage well-being at the workplace through a series of research, experiments, and analyses, to improve the happiness and the productivity. This project adopts the experience sampling method, counting the total number of "what I felt good today" written by individuals, when measuring the degree of well-being. Also, in order to measure gratitude behaviors in the community, we developed copy sticky notes type "thanks card". In the presentation, we will examine the effect of "expressing gratitude" and "receiving gratitude" on the degree of well-being using the results of experiments conducted using the questionnaires and thank you cards.
