  • T. Nakai는 1911년 Flora Koreana vol. II에 러시아 식물분류학자인 V. L. Komarov의 1897년 북한 채집 표본을 120여점 인용하였다. Nakai가 언급한 북한의 지명은 약 65개로서 Komarov의 채집지명의 상당 부분에 해당된다. Nakai가 언급한 지명은 러시아발음에 근간을 두고 로마자로 표기하였는데 최근 혹은 과거 지도에서 정확한 채집지명을 확인하기가 매우 어렵다. 본 연구는 Flora Koreana II에 기재된 채집지명을 과거 발표된 러시아와 일본 번역서인 만주식물지와 표본레이블 등의 자료를 근간으로 Nakai가 언급한 원명과, 한자 지명, 현재 지명의 로마자표기, 위도와 경도, 출처의 페이지 등을 도표로 제시하여 정리하였다.

  • This study aims to develop the 21st century eco design-based fashion products by examining Taller Flora products and presenting eco design approaches. Eco design terms were examined based on literature, and Taller Flora products were explored based on literature and websites. The following research issues were discussed. First, eco design terms are totally handled, thus defining the eco design. Second, eco design-oriented Taller Flora products are examined to explore design approaches. Eco design aims to conserve and heal the global environment with focus on a greater understanding of and interest in nature. As such, eco design is based on a new modern concept of aestheticism that seeks to minimize environmental damage caused by the three processes of production and distribution use and disposal, to take social and moral responsibilities for such activities, and to avoid hurting the environment. Taller Flora brands seek to produce products by keeping close ties with indigenous communities in various nations, and by emphasizing and embracing indigenous people's craftsmanship spirit and creativity Indigenous people use eco-friendly materials and produce products with craftsmanship spirit, and their cooperation by linking different cooperative networks is a good model for strengthening fair trade networks. These addresses the problem of expanding design work through traditional crafting. Therefore, the features of Taller Flora brands presented a new method to approach the eco fashion. The research findings are expected to help develop the eco design of fashion products.

  • A mathematical competition model between normal flora and an invading pathogen was devised to allow analysis of bacterial infections in a host. The normal flora includes the various microorganisms that live on or within the host and act as a primary human immune system. Despite the important role of the normal flora, no mathematical study has been undertaken on models of the interaction between it and invading pathogens against a background of antibiotic treatment. To quantify key elements of bacterial behavior in a host, pairs of nonlinear differential equations were used to describe three categories of human health conditions, namely, healthy, latent infection, and active infection. In addition, a cutoff value was proposed to represent the minimum population level required for survival. The recovery of normal flora after antibiotic treatment was also included in the simulation because of its relation to human health recovery. The significance of each simulation parameter for the bacterial growth model was investigated. The devised simulation showed that bacterial proliferation rate, carrying capacity, initial population levels, and competition intensity have a significant effect on bacterial behavior. Consequently, a model was established to describe competition between normal flora and an infiltrating pathogen. Unlike other population models, the recovery process described by the devised model can describe the human health recovery mechanism.

  • This study is for know chemistry of the representative soils from Keumsan, its relationships with dissolved compositions, and its absorption relationships within the flora. It has been done for two comparisons: 1) phyllite, shale and granite(PSG), and 2) granite and coal bearing shale(GC). Among the soil leachate of the PSG, cations are mainly low in the phyllite area while anions are mainly low in the granite area. In the soil compositions, Ca and Mg of the beans are high and Na is high in the granite area while Ca and Na of the perilla are high in the granite area and Mg is high in the phyllite area. In th both species, Na for the granite area and Mg for the phyllite area are high while Ca for the shale area is low. Among the flora, shale area shows low Ca and Mg contents while granite area shows slightly high Na contents, regardless the species. Compared with beans, perilla is low in the Mg and high in the Na contents. These relationships show that the contents of the soil leachate do not reflect absorption within the flora. Among the soil leachate of the GC, shale area is high in the most of the elements. Especially, SO$_4$ is over 15 times high In the phyllite area. In the soil, granite area shows high Ca, Na and low Mg contents. In the flora, the Miscanthus sinensis shows high Ca and Mg contents in the granite area while the Artemisia vulgaris shows high Ca, Ca and Mg contents in the shale area. These relationships for contents of the flora and soil leachate suggest that the flora has a different absorption according different species.

  • The purpose of this study was to investigate changes in vegetation and flora after five years through field surveys data with the Han Gang Watershed Management Committee (2013) data in order to observe natural vegetation changes in the riparian zone of Han River watershed. As a result, the flora of the riparian zone in 2012 were listed total 231 taxa, 66 families, 158 genus, 207 species, 23 varieties, and 1 forms, and in 2017, a total 247 taxa, 74 families, 174 genus, 218 species, 27 varieties, and 2 forms were identified. The number of rare plants decreased from 4 taxa in 2012 to 2 taxa in total in 2017, and the number of endemic plants increased from 1 taxa to 3 taxa. The number of specific plants by floral region decreased from 21 taxa (9.1% of all 231 taxa of flora) in 2012 to 16 taxa (6.5% of all 247 taxa of flora) in 2017. The total number of naturalized plants is analyzed to increase from 35 taxa, a naturalization rate of 15.15% (all 231 taxa of flora) and urbanization index of 11.2% (all 312 taxa of naturalized plants) in 2012 to 44 taxa a naturalization rate of 17.8% (all 231 taxa of flora) and urbanization index of 14.1%(all 312 taxa of naturalized plants) in 2017. The ecosystem disturbance species showed an increase in both number of species and cover degree grades, indicating that the riparian zone changed in a negative direction.

  • Endemic element of the Russian Far East (RFE) flora includes 497 species of 150 genera and 46 families. The level of endemism in structure of regional natural flora reaches 11.1% as a whole, and in structure of its native fraction - 13.1%. As a result of chorologic and ecocenotic analysis of RFE flora endemic element it is revealed that it consists of 8 main geographical groups and 7 main floristic complexes. The largest number of endemic species is concentrated in Arctic - Alpine & Montane (140, 28.2%), Forest (107, 21.5%) and Maritime (88, 17.7%) floristic complexes as well as in Russian Far East - West-Pacific (136, 27.4%), Japan Sea (88, 17.7%) and North-East-Asian - Beringian (69, 13.9%) geographical groups. It's possible to distinguish three main areas with similar eco-geographical differentiation of endemics on RFE as follows: (1) North-East Asia sector of RFE which North-East-Asian - Beringian and Maritime Okhotia - Beringian geographical groups approximately correspond to, (2) Continental part of East Asia sector of RFE (West - Okhotian, Amur - Okhotian, Amur - Ussirian, Okhotsk Sea and Japan Sea groups) and (3) Oceanic part of East Asia sector (Russian Far East - West Pacific group). Taxonomical variety of RFE endemics on these territories makes up accordingly (1) - 99 species (19.9%), (2) - 259 (52.8%) and (3) - 136 (27.4%).
