Ulcerative colitis (UC) is one of inflammatory bowel disease (IBD), characterized by chronic inflammatory response and dysregulation of immune function. The severity of US has been influenced by environmental factors and food habit. The immune modulatory, anti-inflammatory and steroidal medicine have been used for the treatment of UC. However, long-term administration of those medicine is accompanied with side-effect. So, it is necessary to develop the non side-effect medicine using natural product. Prebiotics influences intestinal condition and food consumption. The heredity, immunity and environmental condition are related with occurrence of UC. In recent study, UC patients had lower level of prebiotics such as Lactobacillus and Bifidobacterium compared with healthy people. Also, previous study announced that imbalance of enteric flora aggravates the severity of UC. The effectiveness of probiotics might affect colon ability and viable bacteria also could promote the proliferation of beneficial intestinal bacteria. Prebiotics, such as herbal medicine, could lead to balance of intestinal bacteria or increase beneficial bacteria. So, proper choice of herbal medicine could control the intestinal condition. This study aimed to investigate the effect of mixture of probiotics and prebiotics (synbiotics) on dextran sulfate sodium (DSS)-induced UC in vivo. The synbiotics consist of Lactobacillus buchneri, Polymnia sonchifolia and Glycine max Merr. in this study. To evaluate the effect of synbiotics, 3% DSS was administered in BALB/c mice and synbiotics was daily administered for experimental days. The administration of synbiotics regulated colon length shortening, body weight change and disease activity index effectively. Also, extract of synbiotics upregulated survival ability of Lactobacillus buchneri in gut condition. These results suggest that mixture of probiotics and prebiotics, called as synbiotics, could influence intestinal condition also regulate the colon disease. Synbiotics might be a therapeutic agent for treatment of UC.

Wild pollinators provide important pollination services for crops. However, their geographical ranges and impact on pollination services have not been fully explored within the scope of Korean agricultural land. This study aims to identify spatial supply-demand mismatches across orchard fields in the context of assessing pollination service risk. We first used National Ecosystem Survey data and a species distribution model (MaxEnt) to develop the geographic range of each of 32 wild pollinators belonging to three families (Diptera, Hymenoptera, and Lepidoptera). We then summed the modeled presence probability of each species to obtain a measure of spatially explicit pollinator richness. This modeled richness, defined as pollination supply, was compared with the summed area of orchard fields at the municipal boundary level to identify areas with supply-demand mismatches. The study found that Lepidoptera showed the highest species richness (8.3±1.5), followed by Hymenoptera (4.3±0.8) and Diptera (3.5±0.8) species. Median orchard area was 1.5 ㎢ (range of 0-176.7 ㎢) among 250 municipal regions in South Korea. The municipal regions were divided into three categories (tertiles) of low, middle, and high pollination supply and demand according to, respectivley, average polliator richness and orhard area. Finally, we found that 55 municipal regions (accounting for 49% of national orchard land) potentially faced high risk of pollination deficits, 81 regions (48% of national orchard land) faced intermediate risk, and 63 regions faced low risk (3% of national orchard land). In conclusion, this study revealed significant mismatch between pollination supply and demand and developed risk assessment map will guide our future efforts on pollinator habitat conservation and monitoring to conserve crop pollination services.

We evaluated the effect of CO₂ offsetting by estimating changes in carbon uptake under various forest management scenarios and proposed forest management strategies to achieve carbon neutrality. Paju and Goseong, which have relatively large forest areas but different industrial characteristics, were selected for the study sites. The current state of forest distribution was analyzed using forest type maps and aerial photographs, and the amount of carbon uptake was calculated using the equation presented by the IPCC Guidelines for National Greenhouse Gas Inventories and the national emission/absorption coefficients from the Korea National Greenhouse Gas Inventory Report. As of 2015, the forest carbon absorption in Paju and Goseong was 49,931 t/yr and 94,225 t/yr, respectively, and the annual carbon absorption per unit area was 2.28 t/ha/yr and 2.16 t/ha/yr. Under the forest management scenarios, the annual maximum carbon absorption per unit area is estimated to increase to 5.68 t/ha/yr in Paju and 4.22 t/ha/yr in Goseong, and this absorption would increase further if urban forests were additionally created. Even if the current forests of Paju and Goseong are maintained as they are, emissions from electricity use can be sufficiently offset. However, by applying appropriate forest management strategies, emissions from sectors other than electricity use could be offset. This study can be applied to the establishment of carbon absorption strategies in the forest sector to achieve carbon neutrality.

The riparian area plays a crucial role in maintaining the balance between the aquatic and terrestrial ecosystems. The Korean government has recognized the importance of protecting riparian areas and has taken steps to purchase land and create ecobelt to reduce non-point source pollutants(NSPs) that can negatively impact water quality. However, selecting the catchment area and calculating the pollution load can be challenging due to the small area of the purchased land and the limitations of low-resolution DEMs. To address these challenges, this study proposes the use of unmanned aerial vehicles(UAVs) to create a high-resolution DEM and calculate the pollution load through land cover analysis. This approach can provide a more accurate representation of the land use status and help to identify areas that are contributing to NSPs. The quantitative comparison of the difference in water quality improvement ecosystem services according to the scenarios of additional catchment areas shows that even land purchased for the same amount of money may have different ecosystem service values, and this was quantitatively calculated. This can be used to prioritize future land acquisition. Overall, this study's approach could provide valuable insights into the effectiveness of ecobelt in reducing NSPs and inform future efforts to protect riparian areas in Korea and beyond.

In Korea, there has been no revegetation applicable standard for slopes formed by road construction work up to now, so revegetation work has been done using mostly foreign varieties in the manner of early revegetation. However, foreign varieties have some shortcomings; for example, they tend to be dried to death after construction work. Besides, due to the rift in the supporting soil, these revegetated varieties are often displaced from the slopes. Thus, the Ministry of Construction & Transportation on July, 2005 established revegetation standard on the slopes suited for the natural eco-system of Korea and organized positively recommending directions for using self-sewn plants growing near the slopes in overall consideration of soil, weather, regional conditions. The locations specified in this direction are the slopes at the road construction jobsite like the expressway, highways, and local roads. In addition, the Ministry's standard and directions stipulated that damaged slopes's natural environment and eco-system due to various road construction work should be restored, and thus a feeling of stability and pleasantness should be provided to road users as well. Also, the Ministry tried to select seed plants and revegetation measures suited for surrounding environment to put the environment-friendly slope revegetation measures into practice through the test revegetation work in order to prevent illegal construction practices and to improve the quality of revegetation. According to the direction, revegetation districts aimed at the slopes are divided into three ones in consideration of weather environment, regional environment, and forest environment as follows : national territory's core ecological green-land based district centering on the Taebaek Mountains; coastal ecosystem district including islands off the coast; inland eco-system district. The combination of revegetation plants according to environment revegetation districts, should be executed by dividing into herb-oriented type, woody plant colony type, and bio-species versatility restoration type, and the selection of seeding plants should be done in the presence of a supervisor and through test construction results and technology counseling from a specialist in natural eco-system restoration and revegetation measure seed combination standard according to environment revegetation districts. This direction will be executed in the manner of monitoring until the yea 2008 and 2009 it will be finalized and enforced on December, 2009.

The purpose of this study was to select herbaceous plants that can be used for presenting various views and biodiversity on the extensive rooftop greening. Experiment plots were constructed in July 2005 on the rooftop of the Administration Building in the Seoul Women's University. For this experiment, planters were used to design rooftop greening. The size of a planter is 500mm${\times}$500mm${\times}$100mm and each planter has the water storage plate in the lower part of it. The soil was constructed by mixing pearlite, vermiculite, cocopeat, and leaf mold in the ratio of 6 : 2 : 1 : 1. The plot was divided into the watered plot and the dry plot. Since each plot was constructed 2 times, finally 4 planters were constructed in total. One hundred species were used for the experiment and 9 plants per species were planted in each planter. Plants were organized according to types of plants and the experiment used 86 native herbaceous plants, 6 herbs, and 8 foreign plants. The plots were monitored once a month, from July to November 2005. The length and width of plants were tape-measured and covering rate was calculated by CAD program. "SPSS 10.1" was used for a statistical analysis. The result showed no significant difference between the watered plots and the dry plots. In cases of some plants, there were statistically significant differences between the watered planter and dry planter such as follows : Astilbe chinensis and Polygonatum odoratum which are shade plants were measured as the highest value on the watered pots, and Aquilegia buergeriana, Chrysanthemum zawadskii, Calendula arvensis and Gypsophila cerastioides D.Don which are sunny plants were measured as the highest value on the dry plots. According to the final analysis of the data collected and observed for growth condition during the first year of the research, 51 species including Prunella vulgaris var. lilacina and Veronica linaiaefolia in native herbaceous plant, 5 species with Lavandula angustifolia in herbs, and 3 species with Lantana camara and Muscari armeniacum in foreign plants showed the highest growth condition. In conclusion, it is suggested that various plants including sedums could be effectively used for extensive rooftop greening to improve landscape(a view) of the rooftop and increase ecological values.

We examined the impact of paddy wetland's avian-diversity on the development of the protected horticulture complex. The results of this study were made to propose ecological protected horticulture complex and development direction suitable for avian habitat. The total number of species surveyed was analyzed as 1168 individuals in 11 orders 26 families and 36 generic 48 species. Type average was analyzed as paddy $17.25{\pm}4.83$ species and $74.50{\pm}38.08$ individuals, glass $10.00{\pm}0.82$ species and $46.75{\pm}2.06$ individuals, single $13.75{\pm}7.27$ species and $59.50{\pm}35.34$ individuals, multi $8.75{\pm}0.96$ species and $36.75{\pm}9.29$ individuals. Paddy showed higher species diversity than protected horticulture complex. The average number of species surveyed for one year was glass $14{\pm}2.83$, multi $12{\pm}1.41$, single $18{\pm}11.31$, and paddy $26{\pm}11.31$. The diversity difference was identified as paddy> single> glass and multi. Statistical analysis showed statistical difference of Ciconiiformes. Development of protected horticulture complex causes loss of avian habitat. The diversity index was glass $1.73{\pm}0.07$, multi $1.68{\pm}0.14$, single $1.91{\pm}0.47$, and paddy $2.29{\pm}0.17$. Paddy has a higher species diversity than the protected horticulture complex. For the purpose of ecological protected horticulture complex, detention ponds, artificial wetlands and habitats should be reflected in the design. This should be applied to reclamation areas or large-scale protected horticulture complexes.
