JOHNSON CITY, Tenn. and KRIVORIVNYA, Ukraine (WJHL) — Pavlo Rybaruk recently shared his experience of participating in East Tennessee State University’s (ETSU) graduation ceremony through a Zoom call. The backdrop for this conversation was particularly symbolic — the dim, chilly lobby of a museum located in his native village within the Ukrainian Carpathian Mountains. The setting was marked by a power outage in a region where electricity is often unreliable.
