This study was performed to assess functions of 10 man-made wetlands in Gunsan City, Jeollabuk Province by means of RAM (Rapid Assessment Method), a technique recommended by Ramsar Convention to appraise wetlands. The assessment of the wetlands value found Gunsan reservoir to have the highest function points while Bukchosan reservoir was estimated to have the lowest function among the wetlands surveyed, By detailed factors of valued 10 man-made wetland, the wetlands were found to function most favorably in terms of vegetational variety and as habitat for wild animals. They need to have more improved functions as habitats for fish and amphibians·reptiles, for preservation and betterment of water quality as well as for supplement of underground water, though. From the assessment of vegetational naturalness of the surveyed reservoirs, Gunsan reservoir turned out to be the most favorable wetland from the viewpoint of vegetation science whereas, however, Anjeong wetland was rated as the lowest in the assessment of vegetational value due to simplicity in its vegetation and lots of dangers in its neighborhood threatening its vegetation and ecology. The assessment of vegetational values for Gunsan, Gongchang, Daewi, Bukchosan, Anjeong, Geumgul, Changan and Chuksan reservoirs showed the same orextremely similar results as RAM function assessment. Geumsan reservoir only, however, featured the opposite result.

Poly(trimethylene terephthalate) (PTT), a semi-crystalline polyester, has been used in many applications because of its good dyeability and good mechanical properties such as elasticity. Sorona (DuPont) and Corterra (Shell Chemicals) are some trade names of PTT. We describe herein a PTT nanofibrous web fabricated by electrospinning, which is a simple technique for generating nanofibers from a polymer solution and a melt. PTT pellets were dissolved in 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) followed by electrospinning to yield PTT nanofibers with an average diameter of $900{\pm}97nm$. Then, the PTT nanofibrous web was impregnated with a polyurethane (PU) solution. The resulting material had better mechanical properties and also displayed a lower water contact angle than the PTT nanofibers because a relatively hydrophilic PU was coated onto the PTT nanofibrous web. Additionally, the pilling property of the PU-impregnated PTT nanofibrous web was enhanced by the induced welding among the PTT nanofibers because of PU impregnation. The air permeability of the PTT nanofibrous web was evaluated both before and after PU-impregnation. The results indicated that the PU-impregnated PTT nanofibrous web could be used in various industrial applications.

The mountain forest vegetation of Gyebangsan (1,577 m) in Odaesan National Park is classified into deciduous broad-leaved forest, mountain valley forest, coniferous forest, subalpine coniferous forest, subalpine deciduous forest, plantation forest, and other vegetation which includes Actinidia argute community and agricultural land. As for the number of communities distributed in the each forest vegetation which were categorized by the physiognomy classification, deciduous broad-leaved forest had 33 communities, mountain valley forest 41 communities, coniferous forest 8 communities, subalpine coniferous forest 4 communities, subalpine deciduous forest 2 communities, plantation forest 6 communities and other vegetation 4 communities. Regarding the distribution rate of communities in the vegetation, in the deciduous broad-leaved forest. Quercus mongolica community accounted for 80.226% with 30,909,942.967m2, followed by Quercus variabilis community of 2.771% with 1,067,479.335m2. 55.463% of deciduous broad-leaved forest in the Gyebangsan had Quercus mongolica as a dominant or second dominant species. In the mountain valley forest, Fraxinus rhynchophylla - Juglans mandshurica community accounted for 10.955%. And there were ten mixed communities having Fraxinus rhynchophylla and upper layer at a similar level of coverage, taking up 32.776%. In the coniferous forest, Pinus densiflora and the community living with Pinus densiflora accounted for 100%, showing that the coniferous forest has the community with Pinus densiflora as a dominant species at upper layer. For other vegetation, subalpine coniferous forest had a total of four communities including Abies holophylla - Quercus mongolica community, and accounted for 4.980% of vegetation area of Odaesan National Park. Two communities including Betula ermani - Cornus controversa community were found in the subalpine deciduous forest, taking up 0.006% of total vegetation area of Odaesan National Park. Regarding plantation forest, Larix leptolepis was planted the most with 51.652%, followed by Betula platyphylla var. japonica with 38.975%, and Pinus koraiensis with 7.969%. These three species combined accounted for 98.565%. In conclusion, the forest vegetation found in the Gyebangsan of Odaesan National Park has Quercus mongolica as a dominant species at the top layer. A lot of other communities related with this species are expected to be quickly replaced due to vegetation succession and climatic causes. Therefore, Quercus mongolica is expected to become the main species in the deciduous broad-leaved forest, Fraxinus rhynchophylla, Juglans mandshurica and Fraxinus mandshurica in the mountain valley forest. Around the border line between deciduous broad-leaved forest and mountain valley forest, highly humid valley area is expected to be quickly taken up by Cornus controversa and Fraxinus mandshurica, and the slope area by Quercus mongolica. However, in the subalpine coniferous forest, the distribution rate of deciduous broad-leaved trees is expected to increase due to climate warming.
