Timely and appropriate water supply to paddy fields is crucial for efficient agricultural water management. In South Korea, 17,240 agricultural reservoirs supply approximately 60% of the agricultural water and play a pivotal role in irrigation and drought mitigation. These reservoirs are managed by the Korea Rural Community Corporation (KRC), which oversees 3,411 reservoirs, and various local governments, which manage 13,829 locations. Guidelines from the Ministry of Agriculture, Food and Rural Affairs (MAFRA) mandate the installation and operation of water level measurement instruments. Currently, automated water level facilities are installed in 1,734 reservoirs and 1,880 irrigation canals, generating water level data at ten-minute intervals. In this study, a survey was conducted to enhance the management of agricultural reservoirs by integrating advanced information and communications technology (ICT) into existing automated water level gauge systems. We propose directions for enhancing the automated water level gauges in agricultural reservoirs. The findings would provide foundational data for stable and systematic management of these gauges.

Liquid filling machines are frequently used in packaging fields; however, there exists a problem in precisely measuring the quantity of the liquid. In the case where the liquid filling machine is not properly metered, there may be issues, such as the fluid exceeding the capacity or chemicals being exposed outside. In this paper, we propose a smart injection nozzle device that can solve the issues stated above. The proposed smart injection nozzle can raise the nozzle according to the water level to remove bubbles and inject the accurate amount of fluid. In addition, the efficiency of the logistics process is enhanced by the smart QR code. Through experiments using the developed smart injection nozzle device, we have noticed that the accuracy of injection capacity, nozzle position, reaction time and building data exceeded the target value. Therefore, it expected that this machine will give more production and save a lot of manpower for packaging industry.
