Answer:
The outcome would be a weakening of the regime, and its probably downfall.
Explanation:
The world Glásnost means "transparency" in Russian. Mikhel Gorbachev, the last Soviet leader, made this word one of the two central policies of his administration (the other being Perestroika, which means "restructuring").
Glásnost brought more freedom of speech in the Soviet Union: people were now allowed to criticize government officials and policies. The government also became more transparent about its actions.
In North Korea, these kind of policies would open the dictatorship to criticism. A specially sensitive subject would be that of human rights violations. The forced labor camps would have to be acknowledged, and this would result in disapproval from the majority of the population. It could also lead to open revolt because of the gravity of the matter.
Just like Glásnost and Perestroika contributed (indirectly) to the downfall of the Soviet Union, Glásnot would accelerate the collapse of the North Korean dictatorship.
