• ついてCommon
  expressionThis is について without the particle に, with essentially the same 'about; concerning' senses. For 'regarding', について is by far the more usual form, so this one is seldom the word you want as given.
  そのことについては私に責任せきにんがあります。↗

  I'm to be blamed for that matter.
• におけるCommon
  expressionIts glosses are 'in; at; on; as for', so it really means 'in' or 'at' a place or context rather than 'regarding' in the sense of 'about'. It is only a marginal match here.
