The purpose of this study ís to identify one aspect of urbanization and urban growth characteristics, viz urban growth stage in Korea. Urban growth stage can be identified through the analysis of population growth and changes in urban functional regions and population density functions in the selected cities. Results of this study show that urban growth stage in Korea differs from the size and locational characteristics of the city. Seoul and Busan, two national metropolitan cities, show similar growth features of ablute decentralization(the fourth stage) in suburbanisation phase during the period 1990-2아)(). The three regional metropolitan cities, Daegu, Gwangju, Daejeon, are all situated in the absolute centralization in urbanization stage, the first stage of urban growth, but Daegu reveals the some features of relative decentralization( the third stage) in suburbanization phase since 1990-2000 period. Almost all small and intermediate cities show some signs of suburbanization within their adrninistrative boundaries but most of them are still situat at the stage of absolute centralization(the first stage) in urbanization phase. Among the secondary cities, Suwon, has shown different growth stage characteristics than the other cities. It revealed the relative centralization(the second stage) characters in urbanization stage in 1970-1990, but moves into the relative decentralization(the third stage) in suburbanization phase since 1990. It indicates an aspect of metropolitization trend of Seoul region.

골연골종은 가장 흔한 양성 골종양이지만 족부에는 적게 발생한다. 특히 거골에 발생한 골연골종은 매우 드물며, 우리나라에서는 보고된 바 없다. 이에 거골에 발생한 골연골종 2예를 보고하고자 한다. An osteochondroma is one of the most common benign bone tumors. The bones of the foot are less commonly involved, and there are only a few case reports of talar osteochondroma. There are no case reports of a talar osteochondroma in Korea. We report two cases of the osteochondroma in the talus.
