K{sup +} total cross sections on deuterium, {sup 6}Li, {sup 12}C, {sup 28}Si and {sup 40}Ca have been measured at four momenta in the range of 480--714 MeV/c. This study has revealed important modifications of the free-space K{sup +}-nucleon interaction when the nucleon is embedded in a nucleus. Some of the suggested modifications include unconventional nuclear medium effects such as partial quark deconfinement, mass rescaling of nuclear pionic fields or pion excess in nuclei and meson exchange currents.
