    Shigekazu Higuchi
    Department of Human Science, Faculty of Design, Kyushu University, Japan
    J Physiol Anthropol 30:251-8. 2011
    ..These results suggest that a red-visor cap is effective in preventing melatonin suppression with no adverse effects on vigilance performance, brightness and visibility...

    Sang Il Lee
    Department of Human Science, Faculty of Design, Kyushu University, 4 9 1 Shiobaru, Minami Ku, Fukuoka 815 8540, Japan
    J Physiol Anthropol 33:9. 2014
    ..This indicates the possibility that OPN4*Ile394Thr is associated with other non-image forming responses. The aim of this study was therefore to determine whether OPN4*Ile394Thr is associated with sleep/wake timing...
