13. Future Plan ▶ Continue monitoring CERN-CKC fellow and grad-student
programs with the aim of ensuring their impact on Korean
science in the future, and optimizing this impact if possible.
▶ Organize 1 CERN-CKC TH Institute in Korea every 3 years
▶ Promote active collaborations with Korean experimental
groups (KCMS and KoALICE) and active participations of
other Korean particle theorists in TH institutes

14. Conclusion
▶ The CERN-Korea theory collaboration program have provided/
will provide Korean young researchers with great opportunities
for accelerating their careers.
▶ The CERN-Korea TH institute program is going well in 2016
and It should keep being fully supported.
▶ We keep promoting close collaborations between Korean
participating members (and other Korean particle physics
theorists) with CERN staffs for world-class HEP researches.
