Quarterly Publication, and Invitation to Artists

More Frequent Publication of the Korean Journal of Radiology: From Quarterly to Bimonthly

ince its first publication as a general radiology scientific journal in 2000, the Korean Journal of Radiology has continuously evolved and improved. In 2005, around 203 manuscripts were submitted to our journal; this increased to around 356 in 2006. More time and thus more reviewers are therefore needed to review these manuscript submissions. The Korean Journal of Radiology now has an electroni...

Mental Rotation in Artists and Non-artists

This research was conducted to compare visuospatial skills in male and female artists and non-artists. Twenty artists (10 males and 10 females) and 20 non-artists (10 males and 10 females) were tested for accuracy and reaction time in a lateralized three-dimensional mental rotation task. Males had significantly fewer errors than females, which is consistent with previous research, but this main...

Invitation to operadic dynamics

Based on the Gerstenhaber Theory it is clarified how operadic dynamics may be introduced. Operadic observables satisfy the Gerstenhaber algebra identities and their time evolution is governed by the Gerstenhaber-Lax or Gerstenhaber-Heisenberg equation. In this way one can describe classical and quantum time evolution of operations. The notion of an operadic Lax pair is introduced as well.

An Invitation to Play

Parity games and their subclasses and variants pop up in various contexts: μ-calculus, tree automata, program verification [3, 1, 8]. Such games provide only binary information indicating the winning player. However, in classical games theory [12] the emphasis is rather on how much we win or lose. Can we incorporate the information about the profits and losses into parity games?
