As the Court has not yet decided the contract with Elsevier ScienceDirect in 2017.
If the required Elsevier Journal's articles are not available on the Elsevier website in 2017,
Please try SDOS (http://sdos.ejournal.ascc.net/)
(Note: Elsevier database from 1995 until the year of stopping order ).
Or contact Mr. Su in the library, will help you to get from the other way.
