الوصف: Harmful gases such as methane and nitrogen gas that occur as domestic livestock industry becomes larger become the cause of environmental pollution. Accordingly, amount of methane gas occurring in the area of livestock is becoming an important area of interest, and many researchers have been continuously conducting experiments to reduce methane gas. This proposed paper methane sensor installed inside shed is comprised of energy- efficient sensor using TinyMD5. The collected methane gas data can be monitored in real-time by user and when the amount of methane gas occurrence inside shed increase, it provides notification service to the user to allow quick response. Cowshed occurring can try to reduce methane gas.

الوصف: Sow culling is one of the key factors determining production cost and operational expenses in the South Korean swine industry. However, most of the farm houses do not consider sow culling as a significant issue. To address this, we, in the present research, extracted data necessary for sow culling from database and applied the AHP technique to help decision making process with comprehensive data. This research is expected to contribute to saving unnecessary production cost and operational expenses by supporting farmers' reasonable decision making
