Great Dharani Sutra of Undefiled Pure Light (Gwi) (LKH 10703) donated by the family of the late Lee Kun-Hee to the National Museum of Korea in 2021 is a calligraphy album consisting of sixty-two leaves compiled using butterfly binding. It contains Great Dharani Sutra of Undefiled Pure Light, "Record of the Production of Mugujeong Pagoda by the Order of King Munseong," a postscript by Kim Jeonghui, and an appreciation record by Oh Sechang. This paper has revealed that this album is identical to the material that Suematsu Yasukazu introduced in Volume 15 of the journal Cheonggu hakchong in 1934 and that it includes elaborate copies of Great Dharani Sutra of Undefiled Pure Light and "Record of the Production of Mugujeong Pagoda by the Order of King Munseong" on yellow Chinese paper, both of which were excavated from inside the Mugujeong Pagoda at Changnimsa Temple in Gyeongju in 1824. It has also reconfirmed that it is highly probable that the Great Dharani Sutra of Undefiled Pure Light that Jo Byeongsun, the former director of the Seongam Old Books Museum, unveiled in 1998, is a transcription of the original sutra excavated from Mugujeong Pagoda at Changnimsa Temple in Gyeongju. Moreover, it has concluded that the Great Dharani Sutra of Undefiled Pure Light owned by Park Cheolsang is likely to be another example of copying the transcription of the original sutra excavated from the Mugujeong Pagoda at Changnimsa Temple in Gyeongju. In the album of copies donated by the estate of Lee KunHee, six of the Chinese characters promulgated by Empress Wu were used fifteen times in total. Four of the characters of Empress Wu were utilized ten times in the Great Dharani Sutra of Undefiled Pure Light (national treasure, Bulguksa Temple collection) found among the reliquaries from the Three-story Stone Pagoda at Bulguksa Temple in Gyeongju and were also seen in the album of copies donated by the estate of Lee Kun-Hee. The use of the same characters of Empress Wu and other variant characters suggests that both the album of copies donated by the estate of Lee Kun-Hee and the Bulguksa sutra were based on an edition distributed in the Unified Silla Period during the eighth century. Kim Jeonghui confirmed the exchange of calligraphy between Korea and China through studies on bronze and stone epigraphs. He believed that the Great Dharani Sutra of Undefiled Pure Light and "Record of the Production of Mugujeong Pagoda by the Order of King Munseong" excavated from Mugujeong Pagoda at Changnimsa Temple were authentic materials showing the elegant calligraphic styles that prevailed before the Ouyang Xun style. Thus, the album of copies donated by the estate of Lee Kun-Hee holds great historical and artistic significance in that it is a rare example of Kim Jeonghui's evidential study of a transcribed sutra and an original record of the production of a pagoda from the Unified Silla period.

Randomly and specifically amplified polymorphic DNA band patterns based on polymerase chain reaction (PCR) analysis were used to assess genetic variation of somaclonal variants obtained from tissue culture of lisianthus (Eustoma grandiflorum). Five different types of variant were classified by morphological characters such as leaflet number, leaf shape, caulicle length, plant height, and leaf area. Five primers out of 20 primers (10 mer) resulted in 34 random amplified DNA fragments with polymorphisms (64.7%) in all tested plants. The dissimilarity coefficient was from 0.71 to 0.91 by UPGMA cluster analysis. Based on the presence of polymorphic bands, normal plant and five somaclonal variants were divided into two groups at the similarity coefficient value of 0.79.

Radiation technique in agriculture was initiated to develop mutant rice. Seeds of Daechungbyeo rice were irradiated with 250 Gy gamma ray for the purpose of inducing and selecting rice variants. Some quantitative traits of the variants in M$_{8}$ generation were evaluated and RAPD analysis was carried out. Variants showed a wider range of agronomic characteristics in both a positive and a negative direction compared with their original variety. The new mutants were characterized by an increased or decreased in plant height, lodging resistance and shorter panicle. RAPD analysis showed that polymorphic bands were presented in most of the primers. In comparison with the original variety, variants were classified into four groups through UPGMA analysis. Among mutants no. 91, 139, 140 and 141 was ranked as salt tolerance and the proline content of these mutants was more increased than that of original variety. The lines of 139, 140 and 141 had the highest genetic distance as compared to original variety in the dendrogram. It is expected that such variants will be useful not only for studying molecular genetics but also for breeding research and genetic analysis.s.
