This study assessed the reliability of the agricultural water supply based on future climate change scenarios, and suggested plans to improve the reliability in order to promote the adaptability of irrigation water in agricultural reservoirs to climate change. The assessment of agricultural water supply reliability was performed on reservoirs which had a lower water quantity than their design basis and which had recently been subject to drought. In other words, from the irrigation districts of main intake works among the reservoirs managed by the Korea Rural Community Corporation, 1~2 districts in each province-that is, a total of 13 districts -that were recently designated as a district for securing agricultural water (drought prevention district) were selected. Climate change scenarios were applied to the selected districts to analyze their future water supply reliability compared to the current level. All districts selected showed a drought frequency of 4 years or shorter, which demonstrated the need to establish climate change response plans. As plans for responding to climate change, a plan that utilizes supplemental intake works to reduce the area of the irrigation districts of main intake works, and another one that increases the capacity of main intake works were adopted to reanalyze their water supply reliability. When the area of the irrigation districts of main intake works was reduced by about 30~40%, the drought frequency dropped to more than 10 years, securing the reliability of water supply. To secure the reliability by increasing the capacity of main intake works, it was calculated that about 19,000~2,400,000 tons need to be added to each reservoir. In addition, climate change response plans were suggested to improve the reliability of the water supply in each district based on the results of economic analysis.

1920년대 후반 상업적인 수경재배 실용화 가능성이 제시된 이래 수경재배는 고효율 농업생산 방식에서 최근에는 친환경 농업생산 시스템으로 자리를 잡고 있다. 이러한 수경재배에서 식물 생장의 양적 질적 측면에서 정확한 급액관리가 중요하다. 그러나 기존 시간제어나 일사량제어로는 정확한 급액관리가 불가능하여 새로운 급액관리 시스템의 개발이 시급한 실정이다. 본 논문에서는 먼저 이러한 급액관리의 특징 및 필요성에 대해 간략히 살펴본 후 자동제어방식의 친환경 급액관리 시스템을 구현하고자 한다. 급액관리 시스템은 전자 제어방식의 자동화 시스템으로 발전시킴으로써 기존의 수동식 배액 제어법의 문제점을 해결할 수 있다. 뿐만 아니라 작물별 생태 특성을 고려하여 여러 종류의 작물들에 적용할 수 있으며, 배지 내 수분 함량을 실시간으로 측정하여 급액관리를 함으로써 기존의 한계를 극복할 수 있다.

Objective : The thromboembolic events during neuroendovascular therapy (NET) are the major complications of concern that can be occasionally fatal. The thrombotic occlusion of the guide catheter for NET is thought to be the risk of the thromboembolic events. We have developed an idea for inventing the monitoring system of the continuous irrigation through the guide catheter. We herein present a unique invention of the guide catheter irrigation monitoring device. Methods : We have developed ideas for preventing the thrombotic occlusion of the guide catheter. In order to design a convenient device working in the practical use, we have consulted and shared the ideas with the electrical engineers about putting the invention. Results : The guide catheter irrigation monitoring device (GCIMD) consisted of three parts of optical sensor, main body and electric adapter. In brief, the basic principles of working of the GCIMD are as follows. The optical sensor is attached to the dripping chamber of the line to irrigation solution. The main body had the small light and speaker to make an alarm sounds. The sensor monitors the dripping of flush solution. If the dripping stops more than three seconds, a warning alarm has been activated. So, the operating physicians can concentrate and check the guide catheter irrigation. After the use of the GCIMD, there was no major thromboembolic complication in conjunction with the thrombotic occlusion of the guide catheter in our institute. Conclusion : We have developed a brilliant invention of the GCIMD for NET.

In this article we developed the environment-friendly arrangement system of drainage and irrigation canal. It is divided into the model which considers ecological conservation type, irrigation flood control type and hydrophilic type. In canal plan and design we will consider vertical section and intersection plan, water quality management, waterside environment construction plan, canal terminal treatment, canal bottom plan, etc. Consequently, We propose the detail contents which must be considered when we plan the environmental canal space.
