The severe effects of climate change, such as global warming and the El Niño phenomenon, have become more prevalent. In recent years, natural disasters such as drought, heavy rain, and typhoons have taken place, resulting in noticeable damage. Korea is affected by droughts that cause damage to rice fields and crops. Societal interest in droughts is growing, and measures are urgently needed to address their impacts. As the demand for high-quality agricultural products expands, farmers have become more interested in water management, and the demand for field irrigation is increasing. Therefore, we investigated water demand in the irrigation of drought-vulnerable crops. Specifically, we determined the water requirements for crops including cabbage, red pepper, apple, and bean in four regions by calculating the consumptive water use (evapotranspiration), effective rainfall, and irrigation capacity. The total consumptive water use (crop evapotranspiration) estimates for Dangjin-si (cabbage), Yesan-gun (apple), Cheongyang-gun (pepper) in Chungnam, and Goesan-gun (bean) in Chungbuk were 33.5, 206.4, 86.1, and 204.5 mm, respectively. The volumes of groundwater available in the four regions were determined to be the following: Dangjin-si, 4,968,000 m³; Yesan-gun, 4,300,000 m³; Cheongyang-gun, 1,114,000 m³, and Goesan-gun, 3,794,000 m³. The annual amounts available for the representative crops, compared to the amount of evapotranspiration, were 313.9% in Dangjin-si, 29.5% in Yesan-gun, 56.1% in Cheongyang-gun, and 20.1% in Goesan-gun.

Yesan-gun was selected to receive a "Village Community Garden Project" in 2018 to foster a sense of community and improve the urban landscape by working with neighbors to create a happy living space for residents. Yesan-gun selected Sapti Park, located in Yesan-eup, as the project site. The project was carried out through the design charrette method (an intense period of collaborative creativity) to allow residents to propose and design park concepts themselves for the community garden construction project to ensure that that the park facilities would provide something for everyone to enjoy. This study followed the actual design project that actively introduced the design charrette in planning the community garden, describing the entire design process from planning to construction and revealing how the opinions of residents were projected onto the design drawings. The purpose of the project was to advance user-participation design methods by reviewing the progress of the design charrette process and to examine how storytelling, the act of conveying ideas through a fun and persuasive story, transformed the plans for the community garden.

Considering irrigation facilities are currently insufficient and drought vulnerability due to climate change is high, efficient measures are required to secure water supply for field crops. This study, therefore, calculated the water shortage to secure water for representative field crops. An economic analysis was further conducted by comparing the production income to the input cost for each method. Here, five distinct regions were selected to represent each crop-Cheongyang-gun for chili peppers, Yesan-gun for apples, Dangjin-si for cabbages, Seosan-si for garlic, and Goesan for beans. The regions with insufficient water supply were estimated by calculating the water requirements and the supplied water from public groundwater wells for each area. A comprehensive set of four scenarios was presented as a strategy to ensure water security and manage irrigation facilities. These scenarios comprised the maintenance of existing groundwater wells, the construction of new water storage tanks, the installation of additional groundwater wells, and the utilization of surface water. B/C (benefit/cost) analysis was conducted for each scenario. As a result, the construction of water storage tanks was selected as a facility and water management plan in Cheongyang-gun, Dangjin-si, and Seosan-si. The analysis additionally indicated the economic viability of installing surface water utilization facilities in Yesan-gun and developing water storage tanks and groundwater (aquifer) wells in Goesan-gun. The results of this study are considered to serve as foundation data that may be utilized in the selection of water management plans for drought-prone areas in the future.

Previously, we identified that Cirsium japonicum (CJ) extract posses antidepressant properties. In order to look for the optimal hebal preparation, CJ extracts collected from Koheung, Yesan, Cheju, Pyungchang and Pocheon were compared. The psychopharmacological activities of each extract were investigated using the open field test, the rota-rod test and the forced swimming test. Effect of each extract on $Cl^-$ influx in neuroblastoma cells were also identified. All of the extracts were orally administered at dosages of 50, 100, 200, 400 mg/kg of body weight. Supplementation of CJ did not significantly alter psychomotor behaviors such as movement, rearing frequency and total turn angle on the open field. Supplementation of CJ's extract from Pyungchang (100 mg/kg, p.o.), Cheju (200 and 400 mg/kg p.o.) and Yesan (100 and 200 mg/kg, p.o.) significantly decreased immobile duration and increased mobile duration in the forced swimming test. All of extracts have no influence on NE uptake in HEK-293 cells, but increased $Cl^-$ influx in neuroblastoma cell. The extract from Yesan demonstrated the most potent effect on $Cl^-$ influx. These results indicate that CJ's extracts from Pyungchang, Cheju and Yesan may alleviate depression, and the extract from Yesan may be the most effective preparation.

The purpose of this study is to conduct an analysis of rural village's community status and consciousness through a questionnaire survey of community leaders and members. Nine types of rural village communities were selected in Korea through a pre-survey of amenity resources data from the Rural Development Administration. Survey items that could determine characteristics of rural village communities were derived from a literature survey of rural village community systems. A questionnaire survey was conducted for 12 Eup-Myeon in Yesan Gun and responses were gathered from 66 community leaders and 1,222 community members. The results derived from the data collected from the community leaders show that 50% percent of rural village communities have been operating for over 25 years, and that community works such as group purchases are carried out based on emotional sympathies between residents. The results derived from the data collected from community members show that on average, community activities are carried out at places that are between 30 and 60 minutes away. Most members are satisfied with regard to the status of their rural village community. A correlation analysis showed that the rural village community satisfaction depended on travel time, community fee, and activity time.

To offer the basic data of vegetation restoration by buried seed of soil, this research was conducted at bare land and abandoned field in Yesan-gun. Germination plants of buried seed were consisted of 40 taxa (37 species, 3 varieties) in bare land, and 41 taxa (37 species, 4 varieties) in abandoned field. Classification of germination plants by family was the most in Gramineae, and emergent frequency of plots was the highest of Digitaria ciliaris. The soil depth of the most plants appearance was 2~5cm in bare land and 5~10cm in abandoned field, and the soil depth of the most population appearance was 0~2cm both in bare land and in abandoned field. Population number of buried seed germination was decreased according to soil depth. Crepidiastrum sonchifolium was a plant that population number of buried seed germination is the most. Similarity index was 0.33 in aerial part plants and buried seed plants, and 0.55 in bare land and abandoned field.
