Literally, "not-yet-converted long-term prisoners"

"Unconverted long-term prisoners" is the North Korean term for northern loyalists imprisoned in South Korea who never renounced Juche. The North Korean government considers them to be "pro-reunification patriotic fighters", while South Korean scholars have described them as "pro-communist spies".
