To evaluate the genetic diversity and structure of the South Korean soybean population, 233 landraces collected in various regions of the country were surveyed for 15 allozyme loci and one protein locus. The South Korean population was fixed or nearly fixed at seven of the 16 loci tested. The number of alleles per locus was 2.06 and Nei’s gene diversity was 0.194. These values were lower than the values for the same 16 loci previously reported for the Japanese and Chinese populations. The differences among eight regional groups were not so marked, with only 7.2% of the total variation arising from regional differentiation. Three southern regional groups (Chollabuk-do, Chollanam-do and Kyong-sangnam-do) exhibited a relatively high variability because of frequent occurrence of alleles characteristic of the Japanese population. A marked difference was found in allelic frequencies at the Dial locus between large-seeded landraces and small-seeded ones, suggesting that the latter, which are used mainly for bean sprouts, had been established independently of the former, which are used mostly for soy sauce and cooking with rice. Not only the region but also the usage as food materials should therefore be taken into consideration in designing an efficient collection and preservation method for the Korean soybean landraces.

Surface water-groundwater interaction (SWGI) is an important hydrological process that influences both the quantity and quality of water resources. However, regional scale SWGI model calibration and uncertainty analysis have been a challenge because integrated models inherently carry a vast number of parameters, modeling assumptions, and inputs, potentially leaving little time and budget to explore questions related to model performance and forecasting. In this study, we have proposed the application of iterative ensemble smoother (IES) for uncertainty analysis and calibration of the widely used integrated surface-subsurface model, SWAT-MODFLOW. SWAT-MODFLOW integrates Soil and Water Assessment Tool (SWAT) and a three-dimensional finite difference model (MODFLOW). The model was calibrated using a parameter estimation tool (PEST). The major advantage of the employed IES is that the number of model runs required for the calibration of an ensemble is independent of the number of adjustable parameters. The pilot point approach was followed to calibrate the aquifer parameters, namely hydraulic conductivity, specific storage, and specific yield. The parameter estimation process for the SWAT model focused primarily on surface-related parameters. The uncertainties both in the streamflow and groundwater level were assessed. The work presented provides valuable insights for future endeavors in coupled surface-subsurface modeling, data collection, model development, and informed decision-making.

춘천지방의 청동기시대 유적과 유물은 주로 범람원에 분포한다. 이 지역의 범람원은 대부분 고도가 높아 홍수시에도 물에 잘 잠기지 않는 자연제방으로 이루어져 있다. 자연제방은 주변의 구릉지나 곡간충적지보다 농경에 있어 훨씬 유리한 조건을 갖추고 있다. 청동기시대 춘천지방의 주민들은 사연제방에 거주하면서 농경에 종사했을 가능성이 매우 높다. 자연제방의 지형적인 특성과 토양을 고려하면 당시 이 지역에서는 벼농사보다 밭농사 중심의 농경이 이루어졌을 것으로 생각된다.

Green tourism is a stay-flow activity between people in urban and rural area, using a natural view, tradition, and life in agricultural area. And green tourism provides rest, recreation, and new experience fur people living in urban area as well as opportunities to increase income for people in rural area. In recently, amenity is rapidly rising as a main factor fur a regional competitiveness. Boseong county shows a typical agriculture industrial structure with a weak independent base, but has a beautiful tea fields in full seasons. Boseong county is making an effort to activate the regional economy, but the result fall short of one's expectation. Several methods to activate the green tourism of Boseong county are as follows: i) introduction of specialized theme relating Boseong green tea; ii) provision of information regarding tourist resort and development of experience-program related to green tea business; iii) establishment of a sales network of products through accommodations in private houses; iv) establishment of networks among regions to achieve systematic sales of tourist experience, accommodations in private houses, and local speciality simultaneously.

The objectives of this study were to compare rural development of Korea and EU. According to its traits the peroids of rural development of Korea can be divided into low periods. According to its memberships and traits the periods of rural development of EU can be divided into low periods. There are many similarities between Korea and EU in agricultural situation and rural development. EU introduced multifunctionality of agriculture in 1980s and adopt strong policy to support that in 1990s. And EU made a effort sustainable rural development, integrated rural development and balanced regional development. Recently Korea not only maintain agricultural expanisionism but also pay attention to multifunctionality of agriculture. But rural development of Korea still in the stage of physical planning and agricultural expanisionism. So it leaves much room for improvement to rural development of Korea in rural development regulation, unifying theme, detail planning, integration among policies, balanced regional development, etc.

The objectives of this study were to establish of resource cycling agricultural system focused on farmer's organization. Case is selected as the farming corporation for the regional agriculture considering the amount of sowing by-products and livestock by-products generated. As a result, generation of fertilizer ingredient depend on feces and urine of Korean native cattle is estimated nitrogen 7.7 ton, phosphoric acid 2.9 ton, and potassium 4.9 ton. On the other hand, generation of fertilizer ingredient demand in cultivated acreage is estimated nitrogen 42.4 ton, phosphoric acid 14.3 ton, and potassium 17.0 ton. Therefore, optimum livestock numbers is estimated 1,867 cattle and it means 1,468 cattle can be raise additionally. In order to complete the resource cycling agricultural system, it should be establish nutrient management system at all of organization level and achieve improvements in regional resource supply. Both economic value of organic fertilizer and the resource cycling system linked market system is considered to develop resource cycling level.

The aim of this paper is to identify Korean agricultural and agri-manufacturing cluster using a multi-regional input-output model. This paper derives a representative set of five agricultural and agri-manufacturing clusters in Korea in terms of spatial and industrial interdependency. The results show that agriculture and agri-manufacturing clusters agglomerated in Seoul Metropolitan Area and Chungcheong Area are linked both production and manufacture functions, whereas Gangwon Area is more focused on production and Jeolla Area is more concentrated on manufacture.

본고는 우하영(禹夏永)이 저술한 "천일록(千一錄)"을 통해 18세기 말 우리 나라 농업의 지역적 특성을 살펴보는 것을 목적으로 하였다. 각 지역의 농업특성은 자연조건 농경지 분포 주요작물 농법 농업생산력 등 "천일록(千一錄)"에서 추출해 낼 수 있는 몇 가지 자료를 통해 분석하였다. 결과 당시의 농업은 오늘날과 달리 각 지역마다 뚜렷한 특성을 지니고 있었다. 그리고 이러한 농업의 지역성은 일차적으로 자연환경의 차이에 기인하여, 지형 기후 토양 등 자연조건이 농경지의 분포와 이용, 주요 작물 등을 좌우하였으며 농업생산력에도 결정적인 영향을 미치는 경우가 많았다. 각 지역의 고유한 농법 역시 농민들이 지역 나름의 자연조건을 감안하여 반복된 시행착오를 거치며 개발 발전시켜 온 것들이었다. 이와 더불어, 각 지역의 인구, 농업노동력의 양과 질, 토지소유의 다과, 수리시설을 비롯한 농업기반시설의 충실도 등사회 경제적 상황도 농업의 지역성을 심화시키는 데 지대한 역할을 하였다.

This study aims to examine the moderating effect of regional agricultural leader's capacity between the sense of community of female farmers and the resident participation. A survey was conducted on 312 female farmers from October 20 to November 19, 2020. The main results of the analysis are as follows. First, it showed that the higher the sense of community, the higher the awareness of resident participation. Second, it was found that the sense of community had a positive effect on resident participation as self-directed learning capability was higher, and that self-directed learning capability had a moderating effect on the relationship between the sense of community and the resident participation. Third, regional agricultural leadership capacity was found to have a moderating effect in the relationship between the sense of community and the resident participation.
