This study aims to analyze the developed characteristics of the knowledge and information of gardens through garden or flowering plant books compiled in the 15th and 19th centuries of Joseon Dynasty. Diachronically analysis of the garden or flowering plant books classified the characteristics in which knowledge and information about gardens are developed by the period, and looked at the factors. The results are as follows; First, the relationship between the authors who compiled the garden or flowering plant books had similar characteristics to the genealogy of Realist School of Confucianism(實學) in the Joseon Dynasty. Kang, Hee-An's practical features influenced later realist school of confucianism scholars. Lee, Su-Gwang has accumulated knowledge of the garden through his experience of traveling the diplomatic envoy to China. Since then, Hong Man-sun's ideology has been related to Charles, a member of the Southerners. Seo Yu-gu was also able to accept Realist School of Confucianism in an integrated way through the Jungnong school's theory and interaction with the Jungsang school. Ryu, Jung-Lim's relationship with the Jungnong school emerged as he added to the 『Jeungbosanrimgyeongje(增補山林經濟)』. Second, the 『Yanghwasorok(養花小錄)』, 『Jibongyuseol(芝峯類說)』 「Hwuimok(卉木)」, 『Hangjeongrok(閑情錄)』, 『Sanrimgyeongje(山林經濟)』 「Yanghwa(養花)」, 『Jeungbosanrimgyeongje(增補山林經濟)』 「Yanghwa(養花)」, 『Hwaamsurok(花庵隨錄)』 and 『Imwongyeongjeji(林園經濟志)』 「Yewonji(藝畹志)」 contain garden plant characteristics, cultivation methods, and management methods. The 『Imwongyeongjeji(林園經濟志)』 「Seomyongji(贍用志)」, 「Iunji(怡雲志)」, 「Sangtaekji(相宅志)」 contain details on the location selection of gardens, the layout of facilities, how to create them and materials. The description of these garden or flowering plant books was found to be the most common introduction with 55 percent, followed by methodologies(42.8%), the Lichi Theory(理氣論, 15.5%), the classification(12.4%), and the convention(1.9%). Third, based on the importance of knowledge and information on gardens, the garden or flowering plant books related to the period were classified as early period, including 『Yanghwasorok(養花小錄)』, 『Jibongyuseol(芝峯類說)』 which were compiled before the 17th century. The 18th-century compiled 『Sanrimgyeongje(山林經濟)』 and 『Jeungbosanrimgyeongje(增補山林經濟)』 were classified as middle period, and the 19th-century compilation of 『Imwongyeongjeji(林園經濟志)』 was classified as late period. The garden or flowering plant books were cited the contents of ancient Chinese books, the author's experiences and opinions contained in the preceding period in later garden books. And the reinforcement of garden knowledge was made to reflect the agricultural technology and expertise developed at the time of writing. Fourth, based on analysis of the development and acceptance of knowledge information in garden by period, In the early period was dealing with floriculture as a way to explore the logic of things. Later, in the 18th century, a vast influx of garden knowledge information came from China. Among scholars, they secured justification for garden creation as part of various knowledge-seeking activities, which expanded their expertise in gardens. In response to the trend of gardening in the 19th century, professional books were written based on knowledge and information on gardens that were collected in the past, and systems were established such as the collection and management of garden plants, construction methods, enjoying methods, and self-realization.

The present study aimed to understand the taste of literati appearing in the Korean-Chinese garden by comparing "Yanghwasorok(養花小錄)" and "Zhangwuzhi(長物志)", which are one of the representative gardens in Korea and China. The main subject of comparison is plants; the research results are as follows. First, Gang Hui-an stated that the ultimate purpose of growing and appreciating the gardening plants is the completion of oneself, while Wen Zhen-heng(文震亨) used gardening plants as a means to practice a life of reclusiveness(隱逸). Second, Gang Hui-an claimed that growing plants is human's cultivation of virtue on the basis of Confucian view's gaining knowledge by the study of things(格物致知), whereas Wen Zhen-heng realized the taste of 'elegance(雅趣)' through form of plants or planting method. Third, although plant preference of literati of both countries is similar in many parts, there is a slight difference for putting gardening plants in pots and appreciating them. For example, even for selecting or placing pots, simplicity and lightness are characteristically reflected from Gang Hui-an while splendor and refinedness are characteristically shown from Wen Zhen-heng. Moreover, in light of the taste of appreciation of literati of the Song Dynasty(宋代), which is a sample of literati spirit, Gang Hui-an inherited the inner world of the spirit whereas Wen Zhen-heng expressed 'literati-ness' in visual images.

This study was carried out to develop effective test method by soybean stink bug and to screen resistant genetic resources against soybean stink bug. The damage pod rate by stink bug showed 40% of most soybean varieties and was selected about 10% low of 10 varieties by 298 variety and degree in soybean at first year Stink bug damage rate research for 102 varieties that stink bug damage rate lowed at first year showed 10% low of 12 varieties and from 20% to 30% of the other varieties. So testing material is "Ilpumgeumjeongkong" to develop for effective test method soybean stink bug and result for stink bug damage rate research of according to growth stage showed rapidly high more full seed than full pod. Full seed stage (R6) was highest to 35.5% for stink bug damage rate. Result of resistant genetic resources selection according to stink bug damage pod rate was lowed of best to 10.3% for "Peking, Sorogkong, Hwangsaegjunjeari and Sobaeknamulkong" in the order. Also, stink bug damage seed rate was similar too. So "Peking, Sorogkong, Hwangsaegjunjeari and Sobaeknamulkong" were thought resistant variety against stink bug. Additional study carried out with "Peking and Sorogkong" so that concretely investigate about stink bug's refuse reaction. This result showed 10.0% for Peking and 14.2% for Sorogkong at R6 stage. But, damage pod rate was rapidly lowed.

Ecklonia cava Kjellman, which has recently gained popularity due to the spread of farming techniques, is expected to be developed in various varieties in the future. There exist increased needs for research on the basis of natural populations and inter-regional morphological variations. We compared the morphology of the aquaculture and natural populations from 16 coastal areas in Korea. The 18 traits found suitable for distinguishing varieties were selected from 14 measurement traits and 4 ratios related to the main morphology and characteristics of primary blade, secondary blade, and stipe. In the cluster analysis, Janggil (E4) and Sorok (S7) showed significant differences from those of the same coastal region. Two groups, including Suyou (Q6, Q8, and Q10) which was the second year of farming, of the rest of the populations from East sea and southern coast were distinguished. Three populations of Jeju were divided into a regional group. In the principal component analysis (PCA), a large number of populations from East sea and Southern coast appeared in the center with aquaculture populations. PC1 and PC2 associated with traits of secondary blade index, stipe length and diameter, stipe length/primary blade length, primary blade length and width, secondary blade number, secondary blade length and width, divided E4, S7 and populations of Jeju region. As a result, the 18 characters of this study were found to be useful as criteria for discrimination of populations with significant differences in each coastal region, and these populations were expected to be candidates for new varieties.

The damping ratio as an index of bridge vibration could be considered as one of the important dynamic characteristics of a suspension bridge. But estimating of damping ratio on an existing suspension bridge under ambient vibration condition could be a laborious task. Moreover, it is not simple to directly distinguish aerodynamic damping and friction damping from apparent damping. According to previous studies, the aerodynamic damping properties can be linearly affected by wind speed level, and apparent damping ratio can be affected by amplitude of vibration. Therefore, in this article, the relationships among damping ratio, wind speed level and amplitude of acceleration were studied for separating extract aerodynamic damping and friction damping from apparent damping. Damping ratios on Sorok Bridge, a suspension bridge which is a located in Go-Heung, Korea, were estimated by two different methods as using Hilbert transform and extended Kalman filter which were well known as effective estimation methods for non-linear state. It was possible to distinguish aerodynamic damping and friction damping from apparent damping using averaged normal components of wind speed, RMQ values of acceleration, and estimated damping ratios from wind-induced vibration responses and vehicle loading responses.

Lichen thalli of Dirinaria applanata heavily colonized on the twigs of dead or dying Rhododendron trees in Solok island, Jeonnam province in Korea. Pathogenesis of the lichen on the trees was investigated to find out the possibility of lichen as a causal agent. Histological examination of the lichen colonized twigs was attempted with differential staining technique. Lichen-forming fungus colonized only on the surface of bark and there was no direct penetration of fungal hyphae into the plant tissues. Symbiotic algae of the lichen was also examined. The isolated algal cells were inoculated on artificially induced wounds of the healthy trees. Histological examination of the inoculated tissues showed that some algal cells were successfully colonized inside the tissues without any pathogenic symptoms, even 2 months later, The extract of the lichen thalli was also examined using 10% of DMSO solution. Treated tissues showed no pathogenic symptoms, even 4 weeks later. The results suggested that the lichen was not directly involved in the death of the trees.

This is a study on the flower pattern artwork of the west wall of the Jagyeongjeon in Gyeongbokgung to find out the type of plants and flowers represented and their symbolism. The research was conducted from July 2010 to March 2011 and the artwork classified on the basis of its horticultural traits. A number was assigned to each pattern for analysis: No. 1 is Prunus mume, No. 2 is Prunus persica, No. 3 is Paeonia suffruticosa, No. 4 is Punica granatum, No. 5 and 6 is Dendranthema grandiflora, No. 7 is Rhododendron mucronu and No. 8 is Phyllostachys bambusoides. These 8 flower patterns symbolize longevity and fecundity and their presense around the Jagyeongjeon helped to bestow good fortune on the royal family so that they might live long lives and bear many children. 4 artworks symbolize longevity, 2 artworks symbolize integrity and 1 artwork symbolizes wealth and happiness. There is also symbolism of the need to have constancy in a royal household even during secular change. Out of the 8 artworks, the imagery of a bird and a moon is represented only once, but the image of a butterfly is represented five times in the surrounding elements. The bird and butterfly symbolise freedom and happiness from free love. Women in the palace are like a butterfly wanted to be like love as a freedom and have a free and open relationship like a butterfly. But a harmonious relationship between the royal family wanted to have a symbolic meaning that could be seen of the symbolistic. Based on the "Yangwhasorok"only plants with the highest values, from the 1st and 2nd grades, were used in the artwork of the west wall of the Jagyeongjeon.

We carried out the experiment to select the suitable sprout soybean varieties for environment-friendly cultivation in paddy field of southern part area, compares of excess moisture injury degree and yield ability among 29 sprout soybean varieties. Plant growth of sprout soybean was generally low in beginning and recovered after flowering due to rainfall. In paddy field cultivation, number of pod per individual and number of seed per individual were less in difference than upland cultivation, and maturing date was delayed 5-14 days than upland cultivation in most species. When environment-friendly cultivation, pest injury was not caused major problem for the growth during the vegetative period of soybean due to ground spider as natural enemy to insect pest. However, damage of stink bugs showed severe during grain filling period, and Dawonkong, Anpyeongkong, Dachaekong and Wonhwangkong showed susceptible to sting bug. SMV infection was weak and showed some necrosis symptoms in Sokangkong, but black root rot was not infected at all. Bacterial pustule began to be infected slowly from pod enlargement stage in most species, displayed severe symptoms in Dawonkong, Pungsannamulkong, Seonamkong and Sobaeknamulkong. The symptoms of pod anthracnose, pod blight and purple spot were greatly appeared after flowering. Disease resistance varieties was Paldokong, Kwangankong, Doremikong, Somyeongkong, Pungsannamulkong, Iksa-namulkong, Seonamkong, Sojinkong, Pureunkong, Bosugkong, Namhaekong and Sorokkong. Lodging index showed 3 in Saebyeolkong, and other species displayed slight lodging in 0-3 degree. 100-seed weight is 9.8-17.2g extent and increased 0.1-3.7g than upland cultivation in most species, but decreased in some species. Government purchase standard, species correspond to small-seed-size namulkong (Sizing screen diameter 4.0-5.6 mm) was Dawonkong, Dachaekong, Bosugkong, Seonamkong, Sokangkong, Hannamkong, Somyeongkong and Wonhwangkong. Species which seed yield was higher than Pungsannamulkong (266kg/10a) were Sorokkong, Hannamkong, Bosugkong and Sowonkong. Considering sprout soybean species, disease endurance, insect resistance, lodging resistance, 100-seed weight, yield ability and excess moisture tolerances synthetically, Seonamkong, Hannamkong, Doremikong, Bosugkong, Pungwonkong, Kwangankong, Sowonkong, Dagikong, Paldokong, Eunhakong and Pungsannamulkong were promising for environment-friendly cultivation in paddy field.
