I participated in Quality Management session and training courses, but it is not even close to my professionality, how can I employ it in my resume?

You need to work and to have experience with minmuam 1 years with what you have subjected above, such as Auditor, participate in quality meeting, be in toutch with quality professionals. Without that it seems usles and you were only in school live!. As well as maintenance field is not related closly to quality!
