This photograph showing hidden beautiful valley with mossy rocks in Moogeonri, Gangwon province, Korea (taken by Jae-Won Doh, member of Korean Neurosurgical Society). The harmony of small waterfall and green moss gives us a refreshing mood enough to dispel the heat of midsummer. As if a drop of water get together to make the river and finally become the sea, every member of Korean Neurosurgical Society should try to do their best to write and submit a good article to JKNS with a hope of making JKNS a world famous journal beyond the SCIE.
