A new gerbera cultivar 'Sunny Lemon' was released by the National Institute of Horticultural and Herbal Science (NIHHS) in 2009. A cross was made between 'Pavlov' and 'Patrick' with pink and semi-double in 2006. After investigation of the characteristics for four years (from 2006 to 2009), it was selected for the use of cut flower. 'Sunny Lemon' is a vigorous cultivar with yellow flower color (RHS Y9C), brown center and semi-double. The average flower diameter is 11.0 cm. And inner ray floret and disc diameter are 7.63 cm and 2.59 cm, respectively. Days to first blooming are 84.5, approximately 2 weeks earlier than the standard cultivar. It produces a large yield with continuous supply of cut flowers and has adequate peduncle height. We believe that 'Sunny Lemon' has a great potential for expanding cultivated area of domestic gerbera cultivars and increasing farmers' income.

The development of medicinal plants for cut plants and landscape plants were conducted through the literiture survey. The results were as follows: We selected 38 species of medicinal plants including 7 medicinal woody plants for cut plant and landscape plants from 450 medicinal plants. There were 8 species of Compositae, 4 species Ranunculaceae, 3 species Rosaceae and Umbelliferae, 2 species Polygonaceae and Campanulaceae respectively. The anthesis of Cornus officinalis, Magnolia denudata, Forsythia koreana of medicinal woody plants flowering before leaf spreading come to early than the anthesis of other medicinal plants. There were 4 species(11%) over 10cm of the flower diameter, 6 species(16%) over 5cm below 10cm, 19 species(50%) over 1cm below 5cm and 9 species(24%) 1cm below. In terms of flower color, 11 species(29%) were white, 9 species(24%) yellow, 6 pecies(16%) red, 5 species(13%) violet and 3 species(8%) were blue aided violet. In terms of the flowering by month, 12 species(32%) on July, 9 species(24%) on May, 6 species(16%) on June and August respectively, and 3 species(8%) on March. The most medicinal plants were propagated by division and seeding easily, but woody medicinal plants of 7 species of this study were propagated by cutting and grafting easily. The percentage of usage of parts of medicinal plants including woody medicinal plants was that roots were 20 species(53%), flowers 6 species(16%), fruits and all part of medicinal plants were 4 species(11%), and seeds and stem including leaves 2 species(5%) respectively.

This study was conducted to improve control system of insect pests, especially western flower thrips, Frankliniella occidentalis, and two-spotted spider mites, Tetreanychus urticae, of rose greenhouses. Density of thrips was relatively higher in yellow flowers than in pink or redflowers, while there was no difference in density of two-spotted spider mites by flower colors. In pest control by an automatic monorail sprayer, 89% labor and 18.2% chemical savings, as compared to the conventional high pressure spray method, were achieved without lowering the pest control effectiveness. By using an adhesive agent in combination with acaricide, adhesion of chemical to crops increased by 25% and control effect on two-spotted spider mites increased by 20.5% as compared acaricide spray alone.

This study was designed to unify two types -traditional and western- of wedding dress in one and to develop new wedding dress which can be used to wedding ceremony as well as Pae-Bae(Greeting) as an alternative for the modernistic utilization of traditional wedding dress. The wedding dress for a bride and bridegroom was developed to be used not only for wedding ceremony but also for engagement. The children's dress which can be worn for carrying flowers in front of a bride and a bridegroom was also developed. All six dresses two of each for a bride and a bridegroom one of each for a body and a girl were developed from the review of literature and photos to be introduced traditional wedding dress. The results were as follows: 1. The Korean characteristics in the developed dress were expressed well in the curves straight lines oblique lines and cracks. 2. The traditional symbolic meanings were expressed by using the pattern which was on traditional wedding dress. Changes from five original colors -red, blue, yellow, white, black- to pastel colors also could modernize the dress. 3. The Korean characteristics could be effectively expressed in dying techniques and piling -up by using hand-made silk and No-Bang, 4. The children's dress for a ceremony was re-established to modernized design with traditional beauty. 5. The expenses could be saved practically because the dress was developed for wedding ceremony as well as for engagement.

Kim Whan-ki is an unusual instance in Korean modern artists, who payed attention to emotional and expressive effects of colors. The color of Whan-ki's paintings have been recognized as linked with 'blue' in spite that he used colors within the category of 'Colors of Five Directions(五方色)', which are traditional oriental colors composed of red, lue, yellow, white, green and black. Kim Whan-ki unearthed upon similarity of Five Directions Colors to the three(five) primary colors which modern abstract painter like Mondrian layed down. Whan-ki switched the five directions colors to modern ones. Kim Whan-ki's dot painting in which pure and watery color is sucked in ground is modernistic adaptation from ink painting. He packs a dot with sky and earth, moon and stars, forest and tree, birds and flowers, friends at his hometown, wind, sound and so on. Putting tens of thousands of these shapes and colors into a dot is modernistic version from ink painting. In that point there is a possibility to say that 'dark blue' of the dot painting is 'Hyun-saec(玄色)'. Eventually we can make sure that Kim Whan-ki's view of Art originated in oriental philosophy and beauty.

Background: Euphorbia jolkinii Boiss. is a perennial species native to Jeju Island and the southern coastal area of Korea. Particularly on Jeju Island, the yellow flowers of E. jolkinii Boiss. have a high ornamental value because of their contrast with basalt. This study was conducted to investigate the effects of different temperatures (5, 15, 20, and 25 ℃) and gibberellic acid (GA₃) concentrations (0, 10, 100, or 1000 mg/L) on seed dormancy and germination of E. jolkinii. In addition, we classified the seed dormancy type and compared types with those of other species in the same genus. Results: The number of seeds with viable embryos and endosperms was approximately 66%. The final germination percentages at 5, 15, 20, and 25 ℃ were 51.7%, 83.5%, 2.6%, and 0.0%, respectively. In GA₃ concentration experiments, the final germination percentages of 0, 10, 100, and 1000 mg/L were 83.5%, 91.7%, 79.1%, and 83.4%, respectively, at 15 ℃ conditions, and 0.0%, 6.9%, 13.2%, and 27.3%, respectively, at 25 ℃. Conclusions: Germination improved at temperatures of 15 ℃ or lower. Furthermore, GA₃ treatment effectively reduced germination times. Thus, the seeds of E. jolkinni were classified as having non-deep physiological dormancy.

The yield and quality of black medick seeds(Medicago lupulina L.) produced from different fertilization and flowering position was investigated was investigated to develop the technology of seed vigor maintenance. Number of flowers and seeds, 100 seeds weight, yellow seed percentage, and large seed percentage were higher in seeds produced from stems than in those from branches. Increase of nitrogen resulted in a higher rate of yellow and large seeds as well as 160 seeds weight. Germination rate was the highest (56.9%) in the yellow seeds harvested from stems which were grown with a treatment of lower level of nitrogen and higher level of phosphorus. Malformed seedlings were frequently observed among the seedlings grown from seeds which were produced only with phosphorus.
