> if b.title_sci=b.title, then we get cc=0

get it, or set it? If the former, what guarantees that the rule is followed?

> if b.title_sci<>b.title then we have to see the master

That contradicts what you wrote before: if base.title_sci = base.title or b.issn1=b.issn2 or b.issn=b.eissn then this is match and CC=0 else cc=1. Which is correct?

> if in master this m.title_sci is dog and for the same row m.title= cat

Loose language yields errors. Especially when writing specs, be literal. Do you mean: if m.title_sci <> m.title?

> then this is match as per the master(a way we say this is match
> though the colun doesnt match in base table )

You seem to mean to say this is a condition for (i) setting b.cc=0 and (ii) consulting the corresponding master row. Is that correct?

You've given apparently inconsistent variants of the condition for setting b.cc=0 and updating the master version of the row. We're writing pseudocode for a requirement. It needs to be unambiguous. Here's your requirement as I understand it so far, unresolved issues I've so far identified are in comments:

in a join of b to m on (title_sci, title, issn1, issn2, issn, eissn, databas) ...

if b.title_sci=b.title or b.issn1=b.issn2 or b.issn=b.eissn then 
  set b.cc=0                   -- WHAT IF B.CC=1?
  if m.cc=0 then
    ???                        -- YOU SAID SET b,cc=0 BUT IT ALREADY IS 
  else if m.title <> m.title_sci
    set .cc=0                  -- OR M.CC?
  end if
else
  set b.cc=1
end if

For readability & clarity, please put your corrected spec, in a format like the above, inside a pair of BBCode code tags (the 1st tag is the word "code", the 2nd is "/code", each surrounded by square brackets).
