  • Recently, many researches for plant alkaloids, one of the largest groups of natural products, are reported because of their various pharmacological activity. This study was carried out to clone putrescine N-methyltransferase (PMT) gene which is a key enzyme in diverting polyamine metabolism towards the biosynthesis of nicotine and related alkaloids from Burley tobacco. To induce expression of PMT gene in tobacco plant, the floral meristem was removed and then mRNA was purified from root. cDNA encoding PMT gene was isolated by RT PCR and cloned. Three different groups of clones were screened by PCR and restriction enzyme digestion analysis and were characterized. The data of these screening revealed that three types of PMT are present in Burley tobacco. Comparison of the nucleotide sequence of this three genes encoding putative PMT with those of other tobaccos revealed that two types of PMT are newly discovered from Nicotiana tabacum cv. Br21 tobacco and they were same as PMT2, PMT3 of N. tabacum cv. Xanthi.

  • The distributional characteristics about 8 syntaxa of mantle communitly (Mantelgesellschaften) in South Korea was studied. This study was carried out by geographic and bioclimatic analysis on 326 phytosociological releves on the basis of syntaxonomy and hierarchical system of mantle community already obtained from Zurich-Montpellier School's method, which involves direct analysis on the latitude, altitude, annual mean temperature and the lowest temperature of each site. The distributional characteristics of mantle communities in South Korea appeared from South to North in the order of Mallotetum japonicae, Clerodendretum trichotomae, Akebietum quinatae, Lonicero-Puerarietum lobatae, Spiraetum salicifoliae. Dioscoreo-Actinidietum argutae, Sorbarietum stellipilae and Tripterygietum regelii. It is suggested that the information (syntaxonomical, floral, geographic and bioclimatic data) of Japan, North Korea and China is essential to determine the distributional characteristics of mantle community in Korean Peninsula.

  • 기업 경영에서 마케팅의 중요성은 더욱 커지고 있으며, 온라인 시장의 확대와 더불어 마케팅 방법이 중요하게 대두되고 있다. 특히, 기업의 경쟁력 확보를 위한 분석과 전략 개발에 기업의 역량을 크게 집중하고 있는 실정이다. 오늘날 꽃시장은 온라인과 오프라인에서 시장이 확대되어지고 있으며, 전국적인 판매망 구축으로 영세하거나 작은 소규모 업체들은 시장진입과 경쟁력 확보가 더욱 어려워지고 있는 실정이다. 이에 본 연구에서는 온라인 환경에서 꽃시장 마케팅 강화를 위해서 기존에 온라인에서 운영중인 대표 사이트들에 대한 서비스 지원 분류와 판매 전략을 살펴보고, 꽃시장에서 마케팅 강화와 고객에게 최적의 서비스를 제공하기 위하여 꽃시장에서 필요하고 경쟁력있는 서비스를 추천하고자 한다. 이를 통해 꽃시장 마케팅 활성화와 경쟁력을 통해 시장의 입지 강화를 기대해 볼 수 있을 것이다.

  • The Illam district, situated in the extreme North Eastern part (Latitude 26.58N and 87.58E Longitude) of Nepal, is a hot spot for floral diversity. The study of wild edible plants of this region was an attempt to highlight the types of wild flowering plants found there and mode of use by the people of the Illam hills. In this respect, a survey of natural resources of some of the representative regions of the district was undertaken and more than 74 major varieties of plant species were found to be used frequently by the people of the hills. The rich diversity occurring in Dioscoriaceae, Moraceae, Rosaceae, Myrtaceae, Poaceae, Urticaceae and Arecaceae provided the wild angiospermic species commonly used by the people of the hills.

  • Floral structures of 11 korean lauraceous species belonging to six genera have been studied. Machilus is a primitive genus having relatively large bisexual flower, six tepals and staminodes in fourth whorl of stamen. The flowers of Neolitsea are highly reduced state as unisexual flower, six stamens arranged to three whorls and no staminode in the flower, so regared as more advanced group. Intrafamilial classification systems of Nakai (1939) and Pax (1891) are more reasonable but still have some discrepancies with results. The origin of tepals of this group has been a long controversial problem; whether the differentiation of tepals occur. Teratological study of Lindera erythrocarpa, inner tepals of this group must be originated from the staminode and outer tepals from leafy tepals. Although morphological differentiation does not sitll occur, inner and outer whorls of tepals are originated through different way.

  • This study was performed to investigate the resources flora of Mt. ManRoi(611.7m; 37$^{\circ}$51'N, 127$^{\circ}$ 20'E), during April 1995 to September 1998. The vascular plants, which were collected from the mountain were composed of all 382 taxa including cultivated species, and classified into 1 phylum, 4 classes, 34 orders, 87 families, 254 genera, 323 species, 1 subspecies,55 varieties and 4 forms. There were not rare and endangered species, while 7 taxa of Korean endemic plants, that is, Tricyitis dilatata, Clematis trichotoma, Deutzia coreana, Spiraea prunifolia var, simpliciflora, Forsythia koreana, Weigela subsessilis and Patrinia sanicalaefalia were distributed in this mountain. The vegetation of this investigated area is regarded as the boundary of the temperate middle part and temperate southern part in floral zone of the Korean Peninsula.

  • The purpose of this study was to investigate the effects of emotion and EEG of people with mental illness by vocational rehabilitation program based on horticultural therapy. The subjects of the study were three people with mental illness who were training in a vocational rehabilitation team at a health center located in G city, Gyeongsangbuk-do. The result of this study, positive affect increased and negative affect decreased. The result of EEG inspection was increased 17.27% on pre test to 21.39% on post test for Theta wave and 39.66% on pre test to 49.02% on post test for Alpha wave in case of subject A. Also Beta wave was decreased 27.53% on pre test to 17.54% on post test. Subject B increased Alpha wave 29.70% on pre to 31.82% on post. Subject C increased Alpha wave 26.30% on pre to 49.42% on post. Beta wave decreased 29.85% on pre to 16.13% on post. Theta wave, when creatively idea or thought occurs, alpha wave when safety and focusing was increased and beta wave when stress, tension and anxiety was decreased. As a result of profits analysis, subject A spent cost a total of 101,700 won for material and achieve profits of 203,400 won by setting a sales price. Therefore, gain the 101,700 won of net revenue. Subject B spent cost a total of 81,000 won for material and achieve profits of 162,000 won by setting a sales price. Therefore, gain the 81,000 won of net revenue. Subject C spent cost a total of 56,200 won for material and achieve profits of 112,400 won by setting a sales price. Therefore, gain the 56,200 won of net revenue.
