In the taxon of family, labiatae, compositae and umbelliferae have larser number of herbs than another families. In the taxon of genus, Rosa (34 kinds), Mentha (8), Thymus (7), Pelargonium (6), Salvia (6), Lavandula (5), Citrus (4), Ocimum (4), Allium (4) in order contain many species. In the geographical floristic regions, Holarctic were 149 kinds, and next came Paleotropical of 26 kinds, Neotropical of 18 kinds, Capetown of 8 kinds, and Australian of 6 kinds in order. Plants growing naturally over 3 geographical region were 4 kinds including Passiflora caerulea. And 166 kinds were growing in the only 1 geographical region. Among the all farms, (1) farm (in Cheongwon) were highest number of 137 kinds. On the other hand, (3) farm (in Cheongsong) were lowest number of 59 kinds. Herb cultivating in all farms were 37 kinds including Pelargonium crispum. Among these, plants of 24 kinds belong to the labiatae family. Also, herb cultivating in the only 1 farm were 50 kinds including Humulus lupulus. About the numbers of usage of herb, the first in numbers was for food $(54.4\%,\;122\;kinds)$ including Ginkgo biloba, the second for medicinal purpose $(39.8\%,\;90\;kinds)$ including Equisetum arvense, the third for cosmetic $(15.9\%,\;36\;kinds)$, th fourth for flavor $(14.2\%,\;32\;kinds)$, the next for perfume $(12.4\%,\;28\;kinds)$, the next for dye $(10.8\%,\;23\;kinds)$, the next for insecticide $(6.6\%,\;15\;kinds)$, the next for ornament $(1.8\%,\;4\;kinds)$, the last for antiseptic $(0.9\%,\;2\;kinds)$.

  • In 2014, surveys were conducted in Korea to study the geographical distribution, host plants, and potential habitats of Pochazia shantungensis. The occurrence of P. shantungensis was confirmed in 43 cities and counties nationwide, and identified for the first time in Gyeongsangbuk-do. P. shantungensis has a wide range of diverse host plants comprising 113 species in 53 families, including crops, fruits, and forest trees. Since the hemipteran was first reported in Korea, 138 species from 62 families have been identified as P. shantungensis host plants. This insect feeds on the following major host plants: Malus pumila, Aralia elata, Styrax japonicus, Salix gracilistyla, Broussonetia kazinoki, Albizia julibrissin, Ailanthus altissima, Castanea crenata, Robinia pseudoacacia, and Cornus officinalis. Potential habitat was analyzed in the present study using the Maxent model with 12 variables (8 climate, 1 land cover, 1 forest type, 1 ecological zoning, and 1 distance). The model ROC AUC was 0.884, indicating a high accuracy. In the present study, precipitation of warmest quater, mean temperature of warmest quarter, forest type, and land cover were the most significant factors affecting P. shantungensis distribution, and habitat.

  • This landscape design proposal was presented to a design competition for the master plan of Ttukseom Sup, which was held by the City of Seoul in March, 2003. The site is located at 1-685, Sungsu-dong, Sung-dong-gu and has an area of 1,156,498$m^2$. The judging criteria for landscape design set by the City of Seoul could be articulated as follows: first, the proposal should be nature-oriented with groves that can be accessed easily by citizens; second, the proposal should not be facilities-oriented but plants-oriented groves that utilize existing plants; third, the proposal should present its own identity reflecting its historical aspects and geographical location. This proposal has been approached first by redefining the meanings of the old Korean village groves and second, by proposing new cultural infrastructures with the groves corresponding to recent cultural trends.

  • This study was conducted to develop the new Environmental Impact Assessment techniques for the grading of rareness in plant. 17 EISs which were submitted in 1996 were analyzed to know the problems in existent EIA techniques for the conservation of rare plants. Category of rare plant was reevaluated and evaluation technique for the grading of rareness in plant was developed. The results obtained from this study were as follows: 1. The evaluation technique of rareness in plant was not reflected in the current preparation provision for EIS. And t his fact also appeared in most of the EIS which were reexamined in this study. 2. The category of rare species which have been considered as the subject of protection in EIA have to be enlarged to more than legally protected species designated by MOE. 3. The taxonomic characteristics and status of species, characteristics of population, geographical characters, extent of threat and its possibility by man resulted from the habitat loss were investigated. Each item was endowed scores from 1 to 5 and all the scores were summed, and then this value was used to evaluate the order of conservation. 4. Conservation measures for the rare plants have to be applied according to the levels of rareness grade, and they are absolute conservation, in situ conservation, transplanting and ex situ conservation, post observation and none by the levels from A to E. 5. Considering the phenology of rare plants, investigation for the rare plants have to be made a1 least three times. 6. Size of the MVP(Minimum Viable Population), pollination ecology also have to be considered for the conservation of rare plants. And in the case of adopting ex situ conservation measure, the site and methods for the conservation of rare plants have to be proposed in detail.

  • A number of plants from different geographical origins have been shown to possess antioxidant activity. Some of them have been developed as natural antioxidant formulations for food, cosmetic and other applications. Bangladeshi flora is a rich source of a range of plant species, many of which are medicinal plants, and have been used in the preparations of the Unani and Ayurvedic traditional medicines. There are no, or just a few, reports on any systematic screening of the extracts of Bangladeshi plants for free radical scavenging activity using DPPH assay available to date. As part of our on-going search for biological activity in Bangladeshi plants, Kadam (Anthocephalus chinensis), Goran (Ceriaps decandra), Swarnalata (Cuscuta reflexa), Gab (Diospyros peregrina), Sundari (Heritiera fomes), Dhundul (Xylocarpus granatum) and Possur (Xylocarpus mekongensis) have been selected for the assessment of their free radical scavenging activity, and studies on the contents of alkaloids, anthraqunones, flavonoids and tannins in these extracts. Most of these species have been used in traditional medicine in Bangladesh and other countries for the treatment of various illnesses ranging from common cold to cancer. All extracts, except the methanol extract of Cuscuta reflexa, displayed significant free radical scavenging activity in the DPPH assay $(RC_{50}$ values within the range of $2.75\;{\times}\;10^{-2}\;to\;4.7\;{\times}\;10^{-3}\;mg/mL)$. Among these extracts, the methanol extract of Xylocarpus granatum exhibited the most potent activity $(4.7\;{\times}\;10^{-3}\;mg/mL)$ and that of Cuscuta reflexa had the least activity $(1.64\;{\times}\;10^{-1}\;mg/mL)$. While none of these plants showed positive tests with Dragendorff's reagent, presence of low to moderate amounts of phenolic compounds, e.g. anthraquinones, flavonoids and tannins was evident in all of these plants, except for the methanolic extracts of C. reflexa and the barks of D. peregrina, which did not display any evidence for the presence of flavonoids and anthraquinones, respectively.

  • The technical development of transportation and communication increases freedom of location choice. This higher freedom allows to company can pursues bigger profit than before. Company's separated spatial configurations tend to go to most optimal location, so some places showed unexpected agglomeration. This study conducted to prove "dispersed concentration" for specific example, pharmaceutical enterprises, in real business world. As a result, separation of spatial configuration clearly observed as product output goes bigger and R&D's depth goes deeper. And spatial concentration of each function was found. Most headquarters are located in Seoul, R&D centers make agglomeration at some spaces. Plants' location concentrated until 1990s, but, in 2000s, plants expand out of metropolitan area.
