  • We investigated the structures of floral organs and the developmental process of each floral organs in Bupleurum falcatum. The overall size of a floral was about 2mm. The lengths of ray, pedicel, pistil and stamen were 22.5mm, 3.6mm, 1.0mm and 1.3mm respectively. The ovary surface was 0.9mm in length and 1.4mm in width. And the developmental periods of each floral organs were as follows; 1 through 6 days in stamen emergence, 6 through 9 days in petal detachment and pistil emergence, 9 through 16 days in pistil ma­turation, and above 16 days in pistil degeneration after onset of flowering. This plant was admitted to be a allogamous plant, especially with the protandry form of dichogamy.

  • In this paper, the funeral was defined as a culture of death and, on the most important ideological basis, the biological death was not recognized as the end of the world, but as a starting point for another life. Various funeral cultures were investigated and the funeral floral design was analyzed through the case. Based on this, it was concluded that Korea's funeral floral design was an impediment to the development of funeral floral design, similar to the use of limited materials. Storytelling, a communicative concept through the exchange of emotions and opinions, rather than unilaterally conveying a message as an answer, is one of the most effective marketing strategies in the emotional consumption era. Based on this, the target person was selected to analyze life and draw suggestions from his life. Accordingly, the production of the work was attempted by applying storytelling to the funeral floral design. The painting design applied to storytelling expressed the symbol and meaning of the painting design material, and the color and form of the floral design in various forms and colors of pastel line, which are based on peach color that symbolizes the deceased, in a departure from the traditional funeral painting design with the solemn atmosphere of the geometric design centered on the white chrysanthemum material.

  • Floral analysis about vegetation of Kimpo landfills and its periphery region was carried out. The study area was defined to a square $(81km^2)$ of which center was located at 250m in front of Andongpo, Komdan-myon, Kimpo-gun in the northwest part of the Kyunggi Province. This study was accomplished by analyzing five qualitative traits such as ecological strategy, reproductive strategy, distribution type, native/foreign division and life-form throughout actual investigation of the flora. The flora was composed of 536 taxa which comprise 105 families, 343 genera, 458 species, 1 subaspecies, 70 varieties and 7 forms (including 92 species of horticultural plant). Lythrum salicaria community, Spiraea salicifolia community, ottelia alismoides community and woods of Alnus japonica were recorded ? 새 retrictive distribution according to habitat characteristics. Owing to severe anthropogenic interferences such as construction of the Kimpo landfills in the study areas, a high proportion of ruderal plants and neophytes in the floral composition was recognized. The proportion of individual distribution type and therophyte was very high throughout whole study areas, and plant communities in the reclaimed areas were characterized by high proportion of phalanx plant species. Analysis of the correlations between meshes with ecological traits of plant species showed that Kimpo landfills and its periphery region was divided into two vegetation types, coastal type and inland type, as a result of possible saline effects.

  • The regulation of flowering time has crucial implications for plant fitness. MicroRNA156 (miR156) represses the floral transition in Arabidopsis thaliana, but the mechanisms regulating its transcription remain unclear. Here, we show that two AGAMOUS-like proteins, AGL15 and AGL18, act as positive regulators of the expression of MIR156. Small RNA northern blot analysis revealed a significant decrease in the levels of mature miR156 in agl15 agl18 double mutants, but not in the single mutants, suggesting that AGL15 and AGL18 co-regulate miR156 expression. Histochemical analysis further indicated that the double mutants showed a reduction in MIR156 promoter strength. The double mutants also showed reduced abundance of pri-miR156a and pri-miR156c, two of the primary transcripts from MIR156 genes. Electrophoretic mobility shift assays demonstrated that AGL15 directly associated with the CArG motifs in the MIR156a/c promoters. AGL18 did not show binding affinity to the CArG motifs, but pull-down and yeast two-hybrid assays showed that AGL18 forms a heterodimer with AGL15. GFP reporter assays and bimolecular fluorescence complementation (BiFC) showed that AGL15 and AGL18 co-localize in the nucleus and confirmed their in vivo interaction. Overexpression of miR156 did not affect the levels of AGL15 and AGL18 transcripts. Taking these data together, we present a model for the transcriptional regulation of MIR156. In this model, AGL15 and AGL18 may form a complex along with other proteins, and bind to the CArG motifs of the promoters of MIR156 to activate the MIR156 expression.

  • Field classes are necessary to grow the ability of and an attitude toward exploring nature and to shape the basic concept of natural science. I tried to develop a site for field classes and the old road Naori's hill is an ideal place with convenient traffic and established youth camps. As a result the vegetation was divided into five associations and communities. The vegetation units obtained in the present study were as follow: Quercus acutissima community, Pinus densiflora community, Pinus densiflora-Quercus acutissima community, Quercus acutissima-Pinus densiflora community, and Quercus mongolica community. In all survey areas 100 family 336 genus 587 species of palants was found. Furthermore, it provides lots of plants throughout the seasons. Not only the flora but also flowering phenology, variety of floral color and growth habits can be used as teaching items. Incorporation of diverse knowledge of plants at the old road Naori's hill into biology teaching will give students academic stimuli and teachers an opportunity of retraining. With a combination of use of visual instruments, the purpose of conceptual and exploring biology is more easily achieved.

  • The present study analyzes the diversity and usage of NTFPs and evaluates their importance in the day to day life of the people of rural Meghalaya. People use 172 NTFPs belonging to 139 plant species mainly for food, medicine and fuelwood and to a lesser extent for construction, handicrafts and ornamental purpose. These 139 plants belonged to 117 genera and 70 families with Rosaceae, Poaceae and Fagaceae families as the dominant NTFP yielding families. Fruits from shrubs and trees are most commonly harvested by people. Collection and availability of NTFPs for use as food are more during the summer season, which is also the period with least availability of job. NTFPs for subsistence use are greater in number than those having commercial value. The most commonly harvested plant parts are fruits and leaves. Roots, rhizomes and whole plants are extracted in lesser quantity which is a positive approach from sustainability point of view. NTFPs and other forest products also form a vital part of the rural household's income generation activities.

  • This thesis analyzes the formal characteristics of Dutch flower still life from the 17th century to the early 18th century and looks into the relevance with the Dutch art market from a macro perspective. The 17th Flower Still Life is to represent social hierarchy in that as the imported exotic, recherch items, the flowers were classified in the terms of their rarity and expensiveness. For this intriguing research, the subject is circumscribed to a vase of flowers, which is the quintessence of In the form of various Dutch Flower Still Life. Dutch society in the early 17th century was centered on the civilian class engaged in trade and commerce, which allowed them to purchase art works to show off their wealth, economic benefits and satisfaction of aesthetic tastes. Among them, the popularity of flower still life was related to the concentrated demand for rare flowers from the new continent. Accordingly, exact depiction and sense of the three dimensional manner were highly regarded in the early flower still life. For the tastes of the wealthy citizens who succeeded in business, the identity of flowers and the actual screen were considered as important. However, after the mid 17th century, economic growth in the Netherlands put an end, and the art market was also on a downward path. The demand class of flower still life has gotten farther away from the spirit of businessmen and has changed into city aristocrats who were stable rentiers. Their tastes laid emphasis on subjective sensibility, which meant that aristocratic, asymmetric, and dramatic chiaroscuro were preferred rather than being realistic. Furthermore, in the 18th century illusionistic realism was abandoned as an expression method of the planar characteristics and a new era in the floral still life was ushered with the reinforcement of decorative effect. From this perspective, it is not an exaggeration to say that romanticism, which is thought of as the beginning of Contemporary Art, originated from the aesthetic taste of Dutch civic culture.

  • The flower arrangement that human beings interact with the natural plants have characteristics according to their historical background and ethnicity and different aspects of culture related of the flower arrangements have been created by human inspiration and formative ability. The Korean flower arrangement is a product of civilization which originated in the natural environment of the four seasons. As background with the natural unity ideology, the Korean Flower Arrangement makes the life and philosophy of the naturalistic nature that flows in the mind of our nation to the relaxing beauty suited on cultures of ages by the Virtue, the Will, and the Vitality. The Literary Flower Arrangement is, based on the higher human personality and poetic sentiments as ideologies of our traditional oriental philosophy, the formative art made for aesthetic implications of philosophy by consisting plants' characters and tastes without expression of technical skills. In this study, focused on pine tree, in order to clarify that the flower arrangement of our spiritual culture is the Literary Flower Arrangement, make Identifying aesthetic characteristics through, the backgrounds and sources of being expressed by the Literary Flower Arrangement, poetic feelings, symbolism, metaphor, the formative form of flower arrangement, decoding of the flower arrangement genes, and the same time deduce the record of literary work and classify it each era, and establish the Literary Flower Arrangement theory which is the essence of Korean flower arrangement.

  • Under the recognition that the technological system of traditional flower design in Korea has been passed down from the past to the present, we extracted the type of design form from the flower decoration of the Joseon Dynasty, analyzed the expression technique, and examined the relationship with the modern traditional flower decoration in this study. As a result, most of the flower design works of the Joseon Dynasty mainly expressed one focal point at the central starting point. One central branch line was mainly used, and cut leaves were mainly used as the base material. Similar to the Joseon Dynasty, one central starting point and a base made of leaves are mainly used In modern flower design. In the frequency of use by expression technique, the stem exposure technique was used the most, and cut flowers and cut stems were used at a similar frequency in all techniques. As plant materials, cut flowers and cut stems were mainly used. In addition, non-plant materials such as feathers, fans, and brushes were also used for decoration. In conclusion, it can be seen that traditional flower decorations in Korea were systematically established in the Joseon Dynasty in terms of expression techniques and high-level flower design works were made. In the future, it will be necessary to study the history of our flower designs in more diverse ways and to develop modern flower designs while preserving historical traditions.

  • Vegetation surveys were performed at 45 plots along 10 highways cut slopes in South Korea. Total floral inventory, species richness and exotic plant percentage were obtained within each plot. Life history and life form of each species appeared were analyzed. Community types were classified using hierarchical cluster analysis and detrended correspondence analysis and non-metric multidimensional scaling were conducted from vegetation matrix. 292 species of vascular plants were discovered and the number of natives and exotics were 226 and 66, respectively. There were no significant differences of species richness and exotic plant percentage between cut slopes and rest areas. Hierarchical cluster analysis indicated five clear vegetation associations in cut slopes and rest areas. Detrended correspondence analysis indicated that species composition of total and native plants were similar along the highway cut slopes whereas exotic plants were distributed differentially along the highway cut slopes. in non-metric multidimensional scaling, the studied sites were more separated from each other on the basis of their species composition than the results of detrended correspondence analysis with respect to total, native and exotic plants. The both ordination represented that exotic plants have not been made uniform yet on cut slopes and rest areas by highway corridor in spite of diverse chronosequences after highway construction termination (1 to 22 years). This study showed that the distribution of species composition in exotic plants was different and localized on cut slopes and rest areas of highway in this representative peninsula area of North East Asia and the invasion of exotic plants can retard the process of plant species homogenization.
