Countries have implicit cultural beliefs and practices about early childhood education which they tend to undervalue and which, as a result, are endangered. The Preschool in Three Cultures Revisited study includes examples of such implicit cultural beliefs and practices in Chinese, Japanese, and US preschools. The paper argues that early childhood practitioners, policy makers, and scholars should give greater value to these cultural beliefs and practices and think of them as national treasures... -

오늘날 현대 미술의 문맥에서 사진은 복제 매체적 특징인 복제와 지표적 특성을 통해 모더니즘의 원본성과 독창성을 부정하며 포스트모더니즘 미술의 중심적 매체로 등장하게 되었다. 사진 인덱스 이론은 이러한 사진의 현대성을 이론적 근거로 밝힘으로써 사진에 대한 단순한 이론을 넘어 현대미술작품의 개념적 원리를 설명하는 근거로써 후기 구조주의적 담론의 중심에 서게 되었다. 이러한 맥락에서 포스트모더니즘 작가들의 적극적인 사진 활용은 현대미술에서의 사진이 갖는 중요한 의미를 시사하고 있다. 현대미술에서의 사진의...
