World Notes SOUTH KOREA

Ever since he approved the enactment of democratic reforms last month, President Chun Doo Hwan has been pressured to fill key posts in his Cabinet with appointees who are not members of the ruling Democratic Justice Party Last week Chun complied -- sort of. He replaced eight D.J.P.-affiliated Cabinet officials with men who do not belong to the party, though most of them, like Chun himself, are associated with the South Korean military. He also appointed a new Prime Minister, Kim Chung Yul, 69, a former air force general who served as Seoul's Ambassador to Washington from 1963 to 1967.

Opposition Leaders Kim Dae Jung and Kim Young Sam pronounced themselves unhappy with the new slate. Chun's selections, they complained, are still too attached to the Establishment to preside fairly over a referendum on direct election of the President and the subsequent national elections expected later this year. Given those feelings, it is just as well that neither of the opposition Kims is kin to Prime Minister Kim.
