Improvement of the efficiency of the agricultural water use is important for the sustainable water management because the agricultural water use occupied above 60% of the total water use in korea. For the analysis of agricultural water use the Yi-dong experimental site was selected. For the monitoring system of the experimental site, four rainfall gauging stations and twenty-six water level gauging stations are established and operated. Analyses of the measured data are processed for the irrigation efficiency of agricultural water on the eight irrigation areas.

최근 한 중 일 및 한 미 FTA가 발효되면 농축산업에 큰 타격을 줄 것으로 예상된다. 수입 자유화 이후 외국에서 생산된 농수축산물의 수입이 급증하고 있다. 그러나 질이 낮은 수입산이 국산으로 둔갑하는 일이 자주 발생하면서 농수축산물의 신뢰도 및 판로에 부정적인 영향을 미쳐왔다. 이에 생산이력 관리에 대한 필요성이 많이 요구되어지고 있다. 본 논문에서는 농산물의 유통이력은 물론 기존 시스템에서 제공하지 못한 생장환경이력정보와 시설재배에 따른 자동제어 및 저장고 모니터링 정보를 추가하여 RFID/USN 기반 농산물 이력관리시스템을 설계 및 구현하였다. 본 논문에서 설계 및 구현한 농산물 이력 관리시스템은 생장환경모니터 링과 이력관리로 구성된다. 첫째, 생장환경모니터 링은 USN을 활용하여 농산 물이 생산되는 재배지의 환경을 모니터링하고 저장고 및 재배시설의 자동제어기를 모니터링 한다. 생장환경모니터링 정보는 농산물의 생장환경에 대한 상세한 정보를 제공해 줄 수 있으며, 생산자가 영농일지를 자동으로 작성할 수 있도록 정보를 제공한다. 둘째, 이력관리는 농산물의 생산, 출하, 유통, 소비까지 모든 유통단계에서 발생된 이력정보를 소비자에게 제공할 수 있다. 본 논문에서 설계 및 구현한 RFID/USN 기반 농산물 이력관리시스템은 생산자에게 u-IT 농업을 제공하고, 소비자에게 농산물에 대한 신뢰도를 높여 줄 수 있다. 또한, 본 시스템을 적용하여 정부의 우수농산물관리제도와 위해 요소중점관리기준을 시행하는 데 기초자료를 제공할 수 있고, 국내 농산물의 고급화 및 선진화를 달성할 수 있다.

Converting the agricultural land-use of rice field to upland has been increasingly conducted as farmers encourages themselves to grow higher value-added crops on rice fields under the policy support. Comparing to rice field, Upland shows different characteristic of discharge due to the slope, scale, and shape of field and characteristics of rainfall event. In this study, we designed the experiment fields reflecting flat-upland characteristics with different land scale, and tried to collect the discharge and load data. Soybeans and corn were selected as target crops considering the possibility of large-scale cultivation and crop demand. The cultivation was conducted during the growth period in 2019 with 3 different field scales. Hence, we have collected the discharge data from 17 rainfall events and the load data for 8 rainfall events. As a result, the magnitude of rainfall events and the discharge duration were found to have a strong positive correlation and field discharge occurred during the period by 55% to 83% of rainfall duration. Besides we found other relationships and characteristics of rainfall event, discharge, and pollutant load and also pointed out that continuous monitoring and more data are required to derive statistically significant results. Compared with slope-field monitoring data obtained from the precedent research, the runoff ratio of the flat-fields was significantly lower than slope-fields. Overall the discharge in the slop and flat-fields shows appreciably different characteristics so that the related researches need to be further conducted to reasonably assess environmental impact of agricultural activities at flat-field.

A seeder monitoring system was developed to solve the problems of mis-sowing and tube clogging in direct seeding machines, which have been one of the factors that reduce the performance of sowing operations. The system consisted of photo sensors, air nozzles, an air compressor, and a one-chip micro-computer based controller. The system was also equipped with the devices that perform the functions of self-checking and intermittent air injection for cleaning seed tubes. The performance of the system was tested in the laboratory and field. Using the well-cleaned rice seed, the average time for checking the mis-sowing was 1.37 seconds in the field and 1.2 seconds in the laboratory without any malfunction. Overall evaluation of the system indicated that the system can be utilized for seeding machines not only for paddies but beans and corns.

The present study aims to monitor three of the community empowerment projects implemented as part of the community central revitalization projects in Yeongwol. We used an established indicator (i.e., quantitative evaluation) as well as an interview (i.e., qualitative evaluation) throughout the monitoring process. The PM (project manager) committee members, consisting of six interdisciplinary experts, carried out the monitoring from $24^{th}$ of October until the $26^{th}$ of November 2018. We categorized the results of the monitoring into the aspects of needs, software, and hardware, and analyzed them as follows: First, although the locals were willing to take part in programs, they were in overall not well informed about the ongoing programs and the program that suits their needs the most. The service organization should therefore actively publicize the program and provide sufficient information about it .Second, instead of a one-off program, the locals should be empowered to take over the program eventually and develop it as a local business model. Last, the locals from the center as well as the outskirts of Yeongwol should organize a learning net, collaboratively develop a further program, and assess its effectiveness by employing a thorough monitoring system.
