As an attempt to determine the identity of the old trees of flowering cherries planted in the yard of the Catholic Archdiocese of Daegu, we conducted comparative phylogenetic analyses between wild and cultivated Prunus yedoensis Matsum. We generated the phylogeny (MP) and haplotype network (TCS) of 25 individuals, including wild P. yedoensis, from Jeju Island, cultivated P. ${\times}$yedoensis 'Somei-yoshino' from Korea and Japan, and P. spachiana f. ascendens (Makino) Kitam. from Jeju Island and Japan based on highly informative sequences of two cpDNA regions (rpl16 gene and trnS-trnG intergenic spacer). The wild and cultivated P. yedoensis were distinguished from each other in both the phylogeny and haplotype networks, and the old flowering cherry trees in Daegu had a cpDNA haplotype identical to that of the cultivated P. ${\times}$yedoensis 'Someiyoshino'. Compared to the cultivated P. ${\times}$yedoensis 'Somei-yoshino', wild P. yedoensis appears to have greater haplotype diversity, presumably originating from the genetic diversity of P. spachiana f. ascendens that functioned as a maternal parent in the hybrid origin of wild P. yedoensis. A future detailed study requires extensive sampling of P. spachiana f. ascendens from Japan and Korea to determine their precise phylogenetic relationships relative to wild and cultivated P. yedoensis. We concluded that the old flowering cherry trees planted in the yard of the Catholic Archdiocese of Daegu are highly likely to be of cultivated origin rather than wild types from Jeju Island, as previously speculated.

This study examines features in using Japanese apricots that assume a leading place with a special symbolism among various species of trees adopted to traditional gardens from a landscaping view. Specific aspects of how Japanese apricots were adopted to traditional gardens are as follows. First, while Japanese apricots are used in modern landscape space, there traditionally were six types in use of Japanese apricots as Tammae(探梅) Jungmae(庭梅) Bunmae(盆梅) Byoungmae(甁梅) Chomae(造梅) and Mukmae(墨梅). Second, Japanese apricots planted in gardens[庭梅] were placed mainly in a front yard of Sarang-Chae(the men's part of a traditional house) took a central area because symbolism and ornamental values of Japanese apricots suited what classical scholars sought. Preferred planting sites at that time include south of the building, the yard of Sarang-Chae, space in front of windows and next to fences and waterside. Third, Japanese apricots in traditional gardens were planted in five ways; Dansik(單植) Daesik(對植) Gunsik(群植) Yeolsik(列植) Honsik(混植). Dansik was the most common way in planting Japanese apricots and Daesik intended to enhance orderedness and symbolism of space. Japanese apricots for appreciating in an open field took the form of Gunsik in general but Honsik was also used with species of special symbolism. This study offers an opportunity to grasp traditional planting methods of Japanese apricots based on understanding of cultural aspects of Japanese apricots by focusing on Japanese apricots, the representative traditional species of trees. Results of the study would help to recognize the need to newly understand Japanese apricots and be useful information to plant and use Japanese apricots in a traditional way.

For finding out the proper method of developing Buxus koreana var. insularis, this study was carried out in Pokil-Do, Wan-Do, Chonnam, in 1975. The ecology, morphology and characteristics of the plant were mainly investigated and analyzed. The results are summarized as follows; 1. The small islands of the southern sea of Korea; Pokil-Do, Chin-Do and So-Huk-San-Do, turn out to be the site of the natural communities of B. koreana var. insularis. 2. The growth of the plant is fairly good in the acid soil of these islands. 3. This vegetation of composed as the three-layered communities, these communities consit of Camellia, Buxus and Cares. 4. The plant is a board leaved evergreen shrub that is tolerant to shade and native to the temperate zone. 5. The size of the leaves, fruits and seeds is slightly larger than those of B. koreans. 6. As fruiting and germination of the seeds are favorable. it is easy for us to make a number of seedlings. 7. The proper times for sowing and harvesting the seeds are around the middle of July and August, respectively. 8. The seedlings is difficult to grow in the naked ground because the germinated seeds are seriously damaged by frost. 9. The plant growth per annum is about 8 to 10cm in height, 1.5mm in diameter. It is graceful looking as the branches and leaves as of the dense foliage type 10. It is possible to develop the plant in many ways, such as; ornamental plant, bee plant, sculptural and industrial materials.

This study was carried out to find out some similarities and differences of the ornamental technique and motifs in folk furniture between Denmark and Korea which had quite different background of development of folk furniture as one of a cross-cultural study. Furniture made and used in the 18th and 19th century was investigated in order to eliminate the influence of internationalism in the design area in the 20th century. This study was fulfilled by many study trips all over the districts in Denmark to identify Danish folk furniture as well as literature study. Study trips to folk museums. Insa-dong, Janghanpyung furniture market were done for Korean folk furniture. Characteristics of ornament in Danish folk furniture were as followings; Main materials of the Danish folk furniture were conifers, especially pine tree, as pine was very common and easy to get from their surroundings. The most popular and unique types of decoration in Danish folk furniture was painting. Colors used in painted furniture were very bright and vivid. This might be a reaction to the long and dark winter of Scandinavian countries. Motifs used in Danish folk furniture had been chosen to reflect their surroundings. Flowers, six-angular stars, animals, human figures and Biblical motifs were popular sources of decoration for Danish folk furniture. Characteristics of Korean folk furniture were as followings; Main materials of Korean folk furniture were broad-leaved trees as well as conifers, because of their beautiful wood grain. The Korean ways of decoration were different from Danish ones. The method of painting with bright from Danish ones. The method of painting with bright colors was hardly ever used in Korea, except only in lacquering. The most popular decoration method for Korean folk furniture was revealing the natural wood grain with transparent vegetable oil finish, instead of painting. Metal ornament was unique to Korean folk furniture. therefore a lot of metal ornaments were attached on the furniture. Motifs used in Korean folk furniture were more like symbolic than Danish ones. Korean people tried to express their longings and norms through the motifs, such as longevity, prosperity, good luck, and many sons, etc. Therefore, it was natural for Korean motifs to have special symbolic meanings.

Ethylene production and inhibition of ethylene production by Ag ion were investigated in ornamental trees injured by $SO_2$ exposure. Concurrently the sulfur content of leaves was measured to examine the absorption of $SO_2$. The results were summarized as follows: 1. Ethylene production by leaves of Pinus thunbergii and Cedrus deodara showed peak after 2 - day exposures to $SO_2$ when visible injury was not appeared ; whereas in Taxus cuspidata showed continuos increase even after 4 - day exposures and was markedly stimulated at leaves appeared visible injury. The amount of ethylene production by leaves of Cedrus deodara and Taxus cuspidata was higher than those of Pinus thunbergii. 2. Ag ion applied on leaves at concentration of 100 ppm $A_gNO_3$ significantly inhibited ethylene production by leaves of Cedrus deodara either $A_gNO_3$ sprayed before $SO_2$ exposure or after leaves were injured by $SO_2$ exposure. 3. The sulfur content of leaves after 5 - day exposures to $SO_2$ showed higher in Pinus thunbergii and Cedrus deodara than in Taxus cuspidata, but there were no great differences in the sulfur content among untreated species.

This study was conducted to select appropriate woody species and to propose appropriate woody species and to propose appropriate mounding hight through analysis of soil characteristics, planting state, draining state, growth amount and injured index of woody species. Soil acidity was pH 5.9~7.4, as alkaline soil. The state of draining was proved to be inappropriate for the growth of woody species because of bad draining state. Injured index of woody species were Prunus serrulata var, spontanea in deciduous tree because of polluted water leaked from sanitary landfill and density of planting tree. Appropriate mounding heignt of the planted area which was itensive injured wood species was not less than 80cm. Appropreate woody species in wanggyoi-dong apartment complex were Zelkova serrata, Acer trifloum, Acer buergerianum, Sophora japonica, Ailanthus altissima and appropriate mounding height was not less than 50~60cm.

This research explores diachronic fashion design trends through a structure analysis of a connection network based on fashion show concepts implemented by modern fashion designers from S/S 2009 to F/W 2013. The findings from this research are as follows. First, four categories affect the inspiration and thinking of design: the experience of the designer, social atmosphere and phenomena, natural sensitivity (or formative characteristics of natural objects), and the influence and quality of other fields. Second, in cases where the designers' experiences influenced design inspiration and thinking, designers express personal memories with keywords like high school, grandmother's closet, prom, beauty and the beast, heritage, past, and reminiscence through design elements such as lines, silhouettes, materials, and colors. Third, the representative example of the social atmosphere and phenomena that influenced design inspiration and thinking was the 2008 Global Financial Crisis that reflected the social climate through design concepts of keywords such as Recession, Black, Economy, US, Depression, Gray, Dark Age, White and New York. Fourth, inspired by nature and the formative characteristics in design, the designers employed ornamental elements to collections and design concepts that focused on nature words connected to light, sun, wild, dirt, rock, moss, and trees. Fifth, the designers took their ideas from different fields of personal interest in the arts, science and humanities (sports, architecture, sculpture, painting, and literature) that were decisive in determining materials, design colors and silhouettes. The theme of architecture was analyzed as a central element that had an ongoing impact on the concepts of designers.

To study for proper growing conditions of Hydrangea macrophylla var. acuminata, used as ornamental trees or sources of natural sweetenings and biological active compounds, two-year-old cuttings of the plant were subjected to different conditions, light intensity, watering, and fertilizing levels. Photosynthetic rates measured on October 2 differed significantly between two light intensity regimes, but the values measured on September 3 were not significantly different. Mean photosynthetic rates on the plot watered three times a week were higher than the cuttings on the plot watered once a week. Mean photosynthetic rates on the plot fertilized 200grams/cuttings were slightly higher than those of the cuttings on the control plot. Chlorophyll contents measured on August 2 and on September 3 were significantly different between the light intensity regimes. Chlorophyll contents measured on August 2 were significantly different between the moisture regimes, but not significantly different between the fertilizing levels. Means of leaf growth(length and width) measured the highest values on the plot watered three times a week, and on the plot in full-sun lighted.

This study was performed to obtain the information on fruit set, propagation and flowering habits of the exotic ornamental bottle brush tree (Callistemon citrinus). Trees have fruit capsules for four years since the fruit set and they have enlarged for three years. While 2 and 3-year-old capsules have similar seeds in number and size, 1-year-old ones have fewer and smaller seeds. Most dried capsules open when they have 75％ relative water contents. Two year old seeds which they were dried at 30％ germinated better than others. Removal of capsule bearing twigs resulted in greatly increased subsequent flower numbers (an average of 14 flowers per tree) compared with twigs where seed capsule were allowed to remain. In cutting for propagation, semi-hard wood branches dipped in 100mgι$^{-1}$ IBA for 24 hours rooted at 86.4 ％ and had an average of 12.6 primary roots.

Environmentally sound control of fall webworm, Hyphanria cunea (Drury) with entomopathogenic nematode, Sreinernema carpocapsae Pocheon strain was evaluated in the laboratory and pot. Pathogenicity of 5. carpocapsae Pocheon strain was different depending on larval stage, i.e., mortality of the 2nd instar and the $3\~4th$ instar was $100\%$ with >20 infective juveniles (Ijs)/larva in 3 days, but the 5th instar was $34\%$ with (Ijs)/larva in 3 days. Pathogenicity of 5. carpocapsae Pocheon strain was higher with increasing nematode concentration. Mortality of Hyphanria cunea larva by 5. carpocapsae Pocheon strain was not significantly different (more than $70\%$) between nematode concentration on treated trees (Malus alba and Platanus orientalis) and in pot.
