  • Sediment-laden water is problematic in aquatic ecosystem and for hydraulic structures in a watershed, and agriculture area in a watershed is one of source areas of nonpoint source (NPS), since soil surface typically exposures due to agricultural activities. Especially, severe sediment might flow into stream when agricultural area is located near stream like the Imha-dam watershed. Soil erosion is affected by precipitation, therefore there is a need to consider precipitation characteristics in soil erosion and best management practices (BMPs) simulation. The Web-based Spreadsheet Tool for the Estimation of Pollutant Load (STEPL WEB) allows estimating long-term sediment loads and the impact of best management practices to reduce sediment loads. STEPL WEB and predicted precipitation data by MIROC-ESM model was used to estimate sediment loads and its reduction by filter strip and conversion of agricultural area to forest in the future 30 years. The result indicates that approximately 70 % of agricultural area requires filter strip installation or that approximately 50 % of agricultural area needs to be converted to forest, for 41 % of sediment load reduction.

  • This study was to design the optimal locations of the water level monitoring to quantify the agricultural water use in irrigation area supplied from an agricultural reservoir. In most of agricultural areas without TM/TC (Tele-Monitoring and Tele-Control) or monitoring network, irrigation water have been supplied on conventional experience and agricultural reservoir have been operated based on the operating simulation results by HOMWRS (Hydrological Operation Model for Water Resources System). Therefore, this study quantified the amount of agricultural water use in an irrigation area (Musu Reservoir, Jincheon-gun) by establishing water level monitoring network and analyzed the agricultural water saving effect. According to the evaluation of the economic values for water saving effect, the saving agricultural water of 1.7 million ton was analyzed to have economic values of 0.85 million won as water for living, and 1.78 million won as water for industrial use. It is identified to secure economic feasibility of the new water monitoring network by establishing one monitoring point in the entrance, irrigation area and endpoint through the economic analysis.

  • The shortage of agricultural labour due to industrial growth has greatly induced the mechanization in Korean agriculture. However small and scattered land holdings have been the main constraints in the process of mechanization. This paper describes the interrelationships of farm land structure, machinery selection and machinery operation areas. The sandy silt loam irrigated paddy land having single crop a year was selected as a target areas for this study. Machine operation cost is greatly influenced by operation period, plot geometry and operation area. On the improved geometry plots, optimal machine size increases slowly with increase in operation area. Operable area increases due to increased effective machine capacity on better geometry plot. The difference between the effects of operation period and plot geometry is that in the former case, the cost reduction is caused by delay in increase of machine size, whereas in the latter case timeliness cost is reduced by increase ffective capacity. The effect of farmland consolidation is greater on small plots than that on big plots. Increasing wage rates have induced the adoption of more labor saving machinery. Bigger labor saving machines require enlargement of operation area and larger plots through improvement in farm land structure. Machine cost on poor plot geometry increases more rapidly than that on the good plot geometry and as operation area increases machine cost reduces significantly. It is concluded that the development of agricultural mechanization ion Korea will depend on the improvement in farm land structure and enlargement of operation area.

  • The purpose of this study was to find out the nationwide general characteristics and housing environments of agricultural households and the differences of them by Eup-Myun Areas. The data were subsample of the 2008 survey on the rural living indicators collected by the rural development administration. Only agricultural households, 73.7% of the original nationwide data (1,461 households out of 1,983) sampled by multi-stage stratified clustering methods and face to face interview in Aug. 2008, were selected and the cross-tabulation(X2) was mainly used to find the difference by Eup Myun areas through spss 12.0 for window. The results showed that the general characteristics of agricultural households such as head of household, family, and economic characteristics were mainly differed by Eup Myun Areas. Agricultural households in Eup area were more likely low in the general characteristics than were those in Myun area. Housing environments were less likely than the general characteristics differed by Eup Myun areas. Improvements of drinking water system, housing alteration, oder, and garbage system were needed to increase the satisfaction with residential environments of agricultural households. This study suggests the use of annual survey on the rural living indicators data would be applicable to various research subjects of home economics.

  • This study intended to compare rural development programs between China and Thailand, focused on research and extension activities. In China, Agricultural Science Administration(ASC) took charges in agricultural research, and under the ASC there were 39 agricultural organizations throughout the country. There were distinctive differences as to condition of agricultural areas, under-developed area at middle and developing area by sea and river. To improve agricultural production in China, diffusion of new agricultural technology would be important along with supplying equipment such as soil test kits, plant nutrition analysis sets and vehcles for extension educators. In Thailand, under the Ministry of Agriculture & Cooperatives, there were five departments, seven divisions and eight national enterprises. Among them, Department of Agriculture was in charge of agricultural research while the Department of Agricultural Extension for extension services. Each department had sub-division and provincial organization including personnel management and budget. However, the relationships and consistency between the Department of Agriculture and the Department of Agricultural Extension needed to be improved for better cooperation of research and extension.

  • In the near future, the multicultural families are expected to be the majority of population living in the rural area, which is an aged and small-scaled society. Moreover, they are expected to have an important role in sustaining the culture of agriculture and a rural community. Therefore, it is very important for them to adjust and settle urgently as well as to develop a policy and social services for the adjustment and settlement. The purpose of this study is to identify different aspects of the participation in agricultural, social, and job activities of married immigrant women in a Korean rural area as well as to investigate the change of life satisfaction resulting from the l activities. The following findings were established from this study. First, married immigrant women participate in local social and agricultural activities in a Korean rural area more frequently than in their own country. However, the frequency of their participation in job activity in a Korean rural area is lower than in their own country. Second, the main factor that prevents married immigrant women from participating in agricultural activity in a Korean rural area is to carry out childcare, household chores, and farming at the same time. Their low participation in social activity and job activity mostly results from their lack of fluency in Korean. Third, married immigrant women score higher in the change of life satisfaction after participating in social activity and job activity than in agricultural activity.
