The Children's Welfare Action Association Seum was established in 2015, for the first time in Korea, to support the "world where children of prisoners live proudly" in terms of children's human rights. In addition to supporting the daily lives of the children of prisoners and their families, it also established a sustainable integrated support platform to pursue changes in the social structure and the system.

Since its establishment, it has provided basic support such as emergency living expenses, daily necessities, and medical treatment expenses, and it has pushed for continuous academic progress through scholarships, as well as providing various mentoring programs so that children of prisoners can lead normal lives. It has also steadily pursued activities like integrated family support to also look after family members other than the children of prisoners. In addition, it has played a leading role in changing policies to protect human rights of children of prisoners by expanding family visiting rights, strengthening human rights protection for the children of prisoners, and by improving social awareness activities.
