Although I lecture on Design Engineering, I deal with topics, including performance (safety and usability, etc.) of structural objects which should be realized by design and reliability as a means of assessing performance, instead of talking about accumulation of knowhow. The time when people thought that the goal of technicians was solely to "create" structural objects is passing, and we are starting to think that the purpose is to contribute to society by structure with design and construction as the means. In that context, it is important to be aware of accountability to the citizen.
