Is this not this one?
Otherwise:
select * from dict where lower(comments) like '%refresh%' and table_name like 'DBA%';

first of all,i want to say thanks for BABU for providing me such useful link on dba views for refresh group.

michel ,

select * from dict where lower(comments) like '%refresh%' and
table_name like 'DBA%';

The result of the query is below;

DBA_SNAPSHOT_REFRESH_TIMES -- Synonym for DBA_MVIEW_REFRESH_TIMES.

Please let me know the purpose of this query?
