This work seeks to examine visible traces of Heavenly Horse天馬 through Li Gonglin’s Five Horses｢五馬圖｣. The conclusions are summarized as follows: First, Li Gonglin’s Five Horses is a painting that consists of more than one painting of a horse. Accordingly, Five Horses is not an official work of Li Gonglin. Second, Heavenly Horse of Song Dynasties was a swift horse born in the Western Region西域 and was a term used to refer especially to the one that the emperors rode. The horses of Five Horses were tributes from foreign countries to the emperors, which were raised in the imperial palace. Therefore, Li Gonglin’s Five Horses shows the appearance of Heavenly Horses of Song Dynasties as they were. Third, Li Gonglin’s paintings made a stylistic standard, so the appearance of Heavenly Horses had no special features. Consequently, it is not false that the horses in Li Gonglin’s Five Horses are illustrations of traditional Heavenly Horse.

This study was conducted to determine the agronomic characteristics of low amylose lines which were derived from induced mutants by T-DNA insertion. The agronomic and physicochemical properties of the low amylose mutants were analyzed and compared with a donor cultivar 'Dongjin' and a low amylose cultivar 'Baekjinju'. The heading date of the low amylose mutants was similar to the donor cultivar 'Dongjin' and yield index of the mutants was 78~92% compared with 'Dongjin'. The amylose content of four mutants in brown rice was ranged from 16.1 to 16.7%. Among low amylose mutants, 'P50-4-4-5' was lower 3.6%(13.3%) than those of 'Dongjin'(16.9%) in amylose content of milled rice. The grain length of 'P50-4-4-5' was similar to the donor cultivar, however, thousand grain weight(18.9g) was lighter than those of 'Dongjin'. The score of alkali digestion in brown rice of 'P50-4-4-5'(5.5) was lower than that of 'Dongjin'(6.8) and similar to 'Baekjinju'(5.8). The gel consistency of 'P50-4-4-5'(84mm) in milled rice exhibited that was longer than 'Dongjin'(76mm) and 'Baekjinju'(81mm). The result of eating quality showed that 'P50-4-4-5'(78.8) was higher than those of 'Dongjin'(60.3) and 'Baekjinju'(67.2). Thus our data suggest that 'P50-4-4-5' will facilitate the development of a new cultivar with low amylose rice.

본 연구의 목적은 미니홈페이지의 게시판 기능을 활용하여 제시하는 주제에 맞는 글을 쓰는 활동이 기존의 전통적인 글쓰기 활동과 비교하여 초등학교 고학년 학생들의 작문 활동에 어떤 영향을 미치는지를 알아보는 것이다. 이를 알아보기 위하여 미니홈페이지의 게시판을 이용한 글쓰기 집단과 공책을 이용한 전통적 글쓰기 집단을 각각 실험 집단과 통제 집단으로 구성하였다. 실험 집단과 통제 집단의 글쓰기 점수를 비교한 결과 유의미한 차이는 나타나지 않았다. 그러나 실험 집단의 실험 전과 후의 점수를 비교해 본 결과, 작문 요소 중 ‘내용의 조직’ 면에서는 긍정적인 영향을 주는 것으로, ‘맞춤법·띄어쓰기’ 면에서는 부정적인 영향을 주는 것으로 나타났다.
