The news is grim, to be sure. But former prisoners in Pyongyang's horrific penal system speculate that the pair may not have to endure the grimmest conditions, which very few have emerged to talk about."
   
   "Kyohwaso life is extremely harsh: scholars estimate only 50% of prisoners survive their first year. One of the first accounts of the North Korean prison system, a 2000 memoir called The Aquariums of Pyongyang, tells of routine torture and deprivations on par with those of Nazi concentration camps." 06-09

3. Ultraviolet Light for Algae Control
   "Even though aquariums require artificial lighting to imitate daylight for the fish, you do not require any type of artificial lights for fish ponds. However ultraviolet lights are primarily used to sterilize as well as filter pond water. This type of technology is also utilized in various industries, by doctors to get sterile water and by campers as well as armed forces for sterilizing their drinking water. Ultraviolet lights for ponds burn out the algae."
   
   Warning: Strong ultraviolet light can damage your eyes if you look into it; avoid looking at ultraviolet light. 11-08
