In an exercise I hear that somebody works as a Senior Economist in a "объединение стéржень" (lit.: unit kernel / core). I don't understand it.
It is in the following link http://www.gwu.edu/~slavic/golosa/audio/audio1-4e.htm
Урок 7. Наша семья
Давайте послушаем 7-39
in 3:20
If the accent would be as с тeржéнь, it could be taken as "works in a unit with ...", but the case would be a problem . I don't know.
Can you make it clear? Thanks.
