ABSTRACT
Well-being described as a further goal after SDGs, is gradually spread out the many worksites. Parallelly advanced technologies has been started to be introduced into tunnel construction sites. Although it is expected that productivity and safety of tunnel workers are supported by such technologies, whether tunnel workers feel well-being by introduction of technologies has never been examined. In Psychology there are two kinds of well-being, Subjective Well-Being (SWB) and Psychological Well-Being (PWB). SWB is an overarching ideology that encompasses such things as “high levels of pleasant emotions and moods, low levels of negative emotions and moods, and high life-satisfaction.” SWB is one definition of happiness. We assumed that SWB involves the feeling of safety and ANSHIN of workers at work. On the other hand, the idea of PWB, Carol Ryff established in the same year consists of six factors, which are positive relationships with others, personal mastery, autonomy, a feeling of purpose and meaning in life, and personal growth and development, which consists of happiness of people. Psychological well-being is attained by achieving a state of balance affected by both challenging and rewarding life events. It is hypothesized that PWB expresses worthwhile of worker at work. Usually both WBs are used to ask general people with questionnaires for happiness with long-span. It has been said that WB is hardly changed for short time. There is no questionnaire or examinations to measure WB at work for workers. Our final goal is establishment of methodology to measure WB of workers at work including tunnel workers. As the first step, we compared the results of well-being between tunnel worker of a major construction company and tunnel miners using existing questionnaires. We examined and checked if WB of workers changed with short span. We found that well-being was quite different between two kinds of tunnel workers.
