  • There are two cultivars, 'Jeongsun' and 'Mishima' of Bupleurum falcatum L., a medicinal plant, have been cultivated in Korea. Two cultivars were evaluated and compared in details for major growth characters and their seasonal changes. Jeongsun was higher in stem length and root weight per plant, and earlier in maturity than Mishima, while Mishima was higher in top weight per plant and the ratio of outer phloem layer(OPL) to whole root, and more in branch number. Coefficients of variations of most growth characters were higher in Mishima than in Jeongsun. In relationship between root and shoot growth characters, root weight, root diameter, etc. were positively correlated with stem thickness, top weight, branch number, etc. in both cultivars. In comparison of seasonal changes for growth characters between two cultivars, stem length and node number were almost not increased after September, but root length and branch number tended to increase until November. There were continuous increases of top and root weights in both cultivars after September. Increase rates of top and root weights were higher in Mishima and Jeongsun, respectively. The weight ratio of root part to whole plant in Jeongsun and the ratio of OPL to whole root in Mishima were higher during whole growth stages; especially Mishima showed their continuous increases after October. Jeongsun flowered earlier (August 17) than Mishima (September 16) by one month. Complete flowering date was on August 30 in Jeongsun and on September 30 in Mishima. Basic difference in plant growth between two cultivars was maturity, so shoot growth almost stopped after October in Jeongsun, and continued vegetative growth until November in Mishima with late flowering habit. These results indicate that higher root weight in Jeongsun is due to its earlier flowering character leading to relatively longer time for root growth, as compared with Mishima.

  • Periodic characters of water temperature in the regions of the Mishima and the Okinoshima were derived through the analysis of the five days interval data during 1914 to 1970 mainly. In terms of ten days mean temperatures, annual variation function of the Mishima region, Korea Strait, is F($\theta_d$)=17.45-5.34 cos $\theta_d$-3.77 sin $\theta_d$+0.62 sin $2\theta_d$ -0.52 sin $3\theta_d$, where $\theta_d$=$\frac{\pi}{18}$(d-2), d is the order of ten days period 1 to 36. And in the region of Okinoshima, Tsushima Strait, we find F($\theta_d$)=18.88-5.39 cos $\theta_d$-3.60 sin $\theta_d$+0.52 sin $2\theta_d$. The annual mean temperature is 17.4$^{\circ}C$ in the Mishima region, 18.9$^{\circ}C$ in the Okinoshima region, and the amplitudes of annual variation functions are 7$^{\circ}C$ in both regions with minimum temperature in the middle ten days of February, maximum in the middle ten days of August. The long term variations of surface water temperature with 12 5 years period were observed in the annual mean temperature, monthly mean temperatures and the fixed day temperatures of every year. In addition to these, relatively short term variations were also found significant periods of 3 years, 4 years and 2 years, respectively.

  • Chromatin structure plays a critical role in the regulation of transcription. Drosophila GAGA factor directs chromatin remodeling to its binding sites. We found that Drosaphiia FACT, a heterodimer of dSPT16 and dSSRPl, is associated with GAGA factor through its dSSRPl subunit, binds to a nucleosome and facilitates GAGA factor-directed chromatin remodeling. Immunostaining of polytene chromosomes revealed colocalization of GAGA factor and FACT in many specific loci. (omitted)

Mishima Yukio's Spring Snow and classics; Focusing on the reproduction of the world of Miyabi (미시마 유키오(三島由紀夫)의 『봄의 눈(春の雪)』과 고전 - 미야비(みやび)의 재현이라는 관점에서 -)

  • This study describes how Mishima Yukio applied various classical motifs in his novel, Spring Snow, to reproduce the world of "Miyabi" of the Heian era. First of all, the author's perception of Japanese culture, focusing on his various critiques and essays was studied. Based on Mishima's cultural theory, analysis revealed that Spring Snow was not based on specific works of the Heian era, but rather on the use of the story form from that era. The background of this novel was the early Taisho era. This period coincided with Japan's political transformation from military power to democracy, and miyabi, or elegance. Finally, the title of this work, "Spring Snow" is an expression found in Kinotsurayuki' Waka in Kokinshu. It represents not only the vanity possessed by the "Spring Snow" reflected in the novel, but also fascination with the beauty of Tsurayuki' Waka.

  • This study was conducted to determine the optimum planting dates and density of one year old Bupleurum falcatum L. to improve its quality. Furthermore, the effect of cultural methods and plant growth regulators$(GA_3,\;IAA,\;Kinetin)$ on the quality of B. falcatum were also investigated. In this study, Jeongseon cultivar collected in Korea and Mishima cultivar introduced from Japan were used. Some of the results obtained are as follows. Jeongseon cultivar showed less stem branches and shoot weight compared to Mishima. However, Jeongseon cultivar showed tall plant height, high root fresh and dry weight, and high levels of SSa and TSS, but low SSc content than that of Mishima. Although fresh and dried root weight of both cultivars were not affected by plant growth regulators treatment. compared with the untreated one, increasement of TSS content were made by $GA_3$ 100 ppm, IAA 50 ppm or 10 ppm and kinetin 10 ppm treatment in Jeongseon cultivar, and by $GA_3$ 10 ppm and IAA 100 ppm or 10ppm treatment in Mishima cultivar applied on June 1.

  • This study was conducted to determine the optimum planting dates and density of one year old Bupleurum falcatum L. to improve its productivity and quality. Two cultivars of B. falcatum, originated from Jeongseon, Korea and Mishima, Japan were used. Some of the results obtained are as follows : Jeongseon cultivar showed less stem branches and shoot weight compared to Mishima. However, Jeongseon cultivar showed tall plant height, high root fresh and dry weight, and high levels of saikosaponin, but low saikosaponin content than that of Mishima. Both cultivars seeded on March 20 had long main root, big stem diameter, few stem branch, and high saikosaponin c content compared to those of late seeded one, April 30. Growth characteristics such as plant height, stem diameter, stem branch number, shoot weight, root diameter, root fresh and dry weight, and root branch number were increased in a low planting $density(30\;{\times}\;15cm)$, but the content of saikosaponin was not affected by planting density. Jeongseon and Mishima cultivars seeded on April 10 with $30\;{\times}\;15cm$ planting density and April 30 with $30\;{\times}\;10cm$ planting density contained the highest total saikosaponin levels, respectively. However, average root dry weight were not affected by planting time or density in both Bupleurum cultivars.
