Hyangju Lee,Changjun Kim,Wonhyeon Lim J-INSTITUTE 2022 International Journal of Crisis & Safety Vol.7 No.2

Purpose: By analyzing 1,441 flora survey data of the 3rd to 5th data of the National Natural Environ-ment Survey, the differences by region and altitude were analyzed in the species number of vascular plants and naturalized plants distributed throughout Korea, and the naturalization index. This study aimed to reveal the correlation by altitude in the species number of vascular plants, the species number of naturalized plants, and the naturalization index. Method: This study utilized the flora survey data for 14 years from 2006 to 2019 in the 3rd to 5th National Natural Environment Survey. One-way ANOVA analysis was performed by region and altitude to examine the differences in the species number of vascular plants, the species number of naturalized plants, and the naturalization index. Researchers performed curvilinear estimation regression analysis to find the correlation, and SPSS Statistics 21 statistical program was used for statistical analysis. Results: There were differences by region and altitude in the species number of vascular plants, the species number of naturalized plants, and the naturalization index. The species number of vascular plants had a positive correlation with an increase in the number of species as the altitude increased. The species number of naturalized plants had a negative correlation with a decrease in the number of species as the altitude increased. The naturalization index had a negative correlation that decreased up to a certain altitude, increased after that point, and then decreased again. Conclusion: As for vascular plants, the higher the altitude, the greater the species number of vascular plants, and the lower the altitude, the fewer vascular plant species. Conversely, as for naturalized plants, the lower the altitude, the greater the species number of naturalized plants, and the higher the altitude, the fewer naturalized plant species. In addition, as for the naturalization index, the lower the altitude, the higher the naturalization index, and the higher the altitude, the lower the naturalization index. This study is expected to be utilized as basic data for managing naturalized plants.

This study was conducted for the purpose of providing basic data for establishing a plant resource conservation and management plan by comprehensively analyzing the vascular flora distributed in Jeongbyeong(Mt.), Changwon-city. Field surveys were conducted on average more than 30 times in 9 courses from February 2014 to November 2020, and the results are summarized as follows. The vascular flora of Jeongbyeongsan(Mt.) was summarized as 464 taxa including 107 families, 275 genera, 404 species, 5 subspecies, 10 forms and 45 varieties. Among them vascular flora identified around Yongchu valley was 319 taxa, accounting for about 69% of the total. The endemic plants were 14 taxa such as Impatiens koreana, Thalictrum actaefolium var. brevistylum and so forth,, and endemic plants rate was 3.01% and 3.89% of 360 taxa of Korean endemic plants. The rare plants were 13 taxa There were 3 taxa as critically endangered species such as Impatiens koreana and Magnolia kobus, 2 taxa as endangered species such as Jeffersonia dubia and Lycoris sanguinea var. koreana, 1 taxa as vulnerable species such as Iris minutiaurea, 6 taxa as least concerned species such as Aristolochia contorta, and 1 taxa as data deficient species such as Chloranthus fortunei. Among these rare plants, 11 taxa except for Tricyrtis macropoda and Iris minutoaurea were found in the vicinity of the Yongchu valley. For these rare plants, research to elucidate the ecological characteristics of their habitats should be conducted. The naturalized plants were 19 taxa including Solanum americanum, Aster pilosus and so forth, and the naturalized index was 4.1%. Invasive alien plants were Ambrosia artemisiifolia and Aster pilosus. The plants of concern for serious invasion into forests were 4 taxa such as Oenothera biennis, Aster pilosus and Erigeron annuus. Of the 19 taxa of naturalized plants, 11 taxa were identified around the Yongchu valley. Since there is a high possibility that the growing environment will be disturbed due to the continuous increase in visitors and intermittent construction, the spread of naturalized plants around the valley area should be monitored. The specific plants by floristic region were 61 taxa; 37 taxa such as Betula schmidtii and Aconitum jaluense of grade I, 3 taxa such as Caryopteris incana and Lilium distichum of grade II, 12 taxa such as Acer palmatum and Adoxa moschatellina of grade III, 4 taxa such as Fallopia sachalinensis and Prunus davidiana of grade IV, 5 taxa such as Impatiens koreana and Jeffersonia dubia of grade V, Target plants adaptable to climate change were 13 taxa; 4 taxa of endemic plants, 1 taxa of northern plant, and 8 taxa of southern plants.

Background: Vascular grafts are mainly composed of synthetic materials, but are prone to thrombosis and intimal hyperplasia at small diameters. Decellularized plant scaffolds have emerged that provide promising alternatives for tissue engineering. We previously developed robust, endothelialized small-diameter vessels from decellularized leatherleaf viburnum. This is the first study to precondition and analyze plant-based vessels under physiological fluid flow and pressure waveforms. Using decellularized leatherleaf viburnum as tissue-engineered grafts for implantation can have profound impacts on healthcare due to their biocompatibility and cost-effective production. Methods: A novel perfusion bioreactor was designed, capable of accurately controlling fluid flow rate and pressure waveforms for preconditioning of small-diameter vascular grafts. A closed-loop system controlled pressure waveforms, mimicking physiological values of 50–120 mmHg at a frequency of 8.75 Hz for fluid flow reaching 5 mL/min. Plant-based vascular grafts were recellularized with endothelial and vascular smooth muscle cells and cultured for up to 3 weeks in this bioreactor. Cell density, scaffold structure and mechanics, thrombogenicity, and immunogenicity of grafts were evaluated. Results: Bioreactor treatment with fluid flow significantly increased luminal endothelial cell density, while pressure waveforms reduced thrombus formation and maintained viable vascular smooth muscle cells within inner layers of grafts compared to static controls. Suture retention of grafts met transplantation standards and white cell viability was suitable for vascular remodeling. Conclusion: Low thrombogenicity of endothelialized leatherleaf viburnum holds great potential for vascular repair. This study provides insight into benefits of conditioning plant-based materials with hemodynamic forces at higher frequencies that have not previously been investigated.
