  • This study was conducted to investigate the influence of eco-friendly restoration in forested bog on the structure of benthic macroinvertebrate community. The benthic macroinvertebrates collected from the surveyed sites were composed of 1,071 individuals, 60 species, 40 families, 13 orders, 6 classes and 5 phyla. At the control and Site 3(small dam), the number of species and individuals were larger than that of other sites, and EPT group ratio was same as well. Considered by index, the dominance index (DI) was found the highest at the biotope area. The diversity index (H') and richness index (RI) were the highest at the control and Site 3. In addition, the ecological score of benthic macroinvertebrate (ESB) showed the highest at site 3, while the lowest at biotope area. The stability and recovery of benthic macrointebrates showed different according to restoration types at forested bog. After restoration project, the benthic macroinvertebrates were observed to get recovery at Site 3, and to have the highest communities stability at control and Site 3. At biotope areas (Site 4, Site 5 and Site 6) communities stability were the lowest, but showed different community stability values according to the presence of water. It is confirmed that the eco-friendly restoration projects indeed provided the better environment for the inhabitation of benthic macroinvertebrate community. The change of community index depending on the restoration projects suggests that the eco-friendly restoration can provide a more suitable environment for benthic macroinvertebrate ecosystem that prefers the stream environment.

  • Since the tourism complex development projects is promoted for areas with good natural environment and excellent landscapes, it has s significant environmental impact on the surrounding area. Therefore, this study investigated the current status and various environmental influences of tourist complex based on environmental impact assessment reports from 2012 to 2021. Based on the results of the current status analysis of the development projects, EA-INDEX for the tourism complex development projects was developed and applied to comprehensively and quantitatively analyze various environmental impacts. Through this, we investigated eco-friendliness of the development projects by year in the natural environment conservation sector, resource conservation sector, and living environment protection sector. As a result we found that the tourism complex development projects were carried out in a way that increases eco-friendliness over the past ten years, especially in in the natural environment conservation sector. On the other hand, in the case of resource conservation, it has been confirmed that eco-friendliness is decreasing, so it is necessary to make efforts to improve it when establishing new development plans in the future. It is expected that the result of this study will be useful for identifying the development trend and environmental impact of development projects. If an analysis is made that synthesizes information such as policy events and social issues related to development projects in the future, it is also expected that a broader explanation will be possible to identify trends in development projects using EA-INDEX.

  • Vegetation processes have a significant impact on rainfall runoff processes through evapotranspiration control, but are rarely considered in the conceptual lumped hydrological model. This study evaluated the model performance of the Hapcheon Dam watershed by integrating the ecological module expressing the leaf area index data sensed remotely from the satellite into the hydrological partition module. The proposed eco-hydrological model has three main features to better represent the eco-hydrological process in humid regions. 1) The growth rate of vegetation is constrained by water shortage stress in the watershed. 2) The maximum growth of vegetation is limited by the energy of the watershed climate. 3) The interaction of vegetation and aquifers is reflected. The proposed model simultaneously simulates hydrologic components and vegetation dynamics of watershed scale. The following findings were found from the validation results using the model parameters estimated by the SCEM algorithm. 1) Estimating the parameters of the eco-hydrological model using the leaf area index and streamflow data can predict the streamflow with similar accuracy and robustness to the hydrological model without the ecological module. 2) Using the remotely sensed leaf area index without filtering as input data is not helpful in estimating streamflow. 3) The integrated eco-hydrological model can provide an excellent estimate of the seasonal variability of the leaf area index.

  • The present study was undertaken to evaluate effects of eco-friendly underwears(three kinds of natural dying underwears) in patients with atopic dermatitis. We recruited 45 patients with atopic dermatitis admitted to Dongshin Oriental Hospital from August to September 2013. These patients were divided into three groups (A, B and C). Each group include 15 patients and three kinds of natural underwears dyed with polygonum tinctorium, loess, and non-dyed general cotton were given, respectively. We also used SCORAD index and digital infrared thermal imaging to investigate the effects of each eco-friendly underwear in patients with atopic dermatitis. In SCORAD index, Group A after wearing loess-dyed underwears for 4 weeks showed statistically significant reduction to 27.96 (P<0.05) compared to 34.20 before wearing loess-dyed underwears. In Group B after wearing polygonum tinctorium-dyed underwears for 4 weeks, SCORAD index and objective severity assessment were markedly reduced into 22.97 (P<0.01) and 18.17 (P<0.01) compared to 35.95 and 27.89 before wearing polygonum tinctorium.-dyed underwears, respectively. In Group C after wearing general cotton (non-dyed) underwears for 4 weeks, there was statistically no difference in SCORAD index, objective severity assessment and body temperature between before and after wearing general cotton (non-dyed) underwears. Taken together, polygonum tinctorium-dyed underwears used to patients with atopic dermatitis shows significant amelioration in atopic symptoms than loess-dyed underwears as well as general cotton (non-dyed) underwears.

  • Cometabolism technology was employed to degrade lignin wastewater in Sequencing Batch Biofilm Reactor. Cometabolic system (with glucose and lignin in inflow) and the control group (only lignin in inflow) were established to do a comparative study. In contrast with the control group, the average removal rates of lignin increased by 14.7% and total oarganic carbon increased by 32% in the cometabolic system with glucose as growth substrate, under the condition of 5 mg/L DO, $0.2kgCOD/(m^3{\cdot}d)$ lignin and glucose $1.0kgCOD/(m^3{\cdot}d)$. Functional groups of lignin are degraded effectively in cometabolic system proved by fourier transform infrared spectroscopy and Gas Chromatography-Mass Spectrometer, and the degradation products were amides (mainly including acetamide, N-ethylacetamide and N, N-diethylacetamide), alcohols (mainly including glycerol and ethylene glycol) and acids. Meanwhile, results of Polymerase Chain Reaction-Denaturing Gradient Gel Electrophoresis showed great differences in microbial population richness between cometabolic system and the control group. The Margalef's richness index and Shannon-Wiener's diversity index of microorganism in cometabolic system were 3.075 and 2.61, respectively. The results showed that extra addition of glucose, with a concentration of 943 mg/L, was beneficial to lignin biodegradation in cometabolic system.
