With enforcement of five-day workweek system, leisure time for family has increased. However, there is imbalance between demand and supply of leisure because of the absence of proper way for spending leisure time with family. On the other hand, TV, which has been playing an important role as a media for family, shows new possibility of interaction with advent of Smart TV. With this tendency, now it could be an appropriate time for researching the healthy way to spend leisure time on weekend with family. Therefore this paper aims to propose a family farming contents called 'Our Farm', which links on-line and off-line. To firm up necessity and appropriateness of this paper, I analyzed existing thesis and games for family and did FGI(Focus Group Interview) with a family. In this research, I proposed the picture UI based on results of investigation.

Purpose: A chisel mounted on working implement, such as agricultural machinery used in irregular farming conditions, is subjected to highly variable fatigue loading during work. To ensure the safety of the chisel on a working implement for the duration of its service life, fatigue testing must be performed with the proper fatigue test load conditions. In this study, working loads for a chisel were developed by reconstructing loads from strain gage data collected during field tests and used to conduct fatigue tests on the chisel component. Methods: FE analysis with nCode software was utilized to select the proper quantity and locations of strain gages for load measurements. A fatigue test was performed to experimentally verify the fatigue strength of the chisel and to evaluate the validity of the load history developed with the load reconstruction technique. Results: A strain history for the chisel was obtained from data collected during field tests. The data was filtered for the 14-16 km/h speed range, connected, and merged. The chisel load history was developed using the load reconstruction technique. The resulting load history was expressed as a load spectrum using the rain-flow counting method. Conclusions: A fatigue test was conducted on a chisel under a constant load condition with an equivalent load amplitude and number of cycles, as calculated by Miner's Rule for linear damage accumulation. During the fatigue test, there were no cracks at any position. It is concluded that the fatigue test method proposed in this study can be utilized successfully as a durability evaluation method for the chisel.

The agricultural environment is changing and becoming more advanced due to the influence of the 4th Industrial Revolution. From the basic plan of Rural Informatics to the current level of 2nd generation smart farms aimed at improving productivity using Big data, cloud network and more IoT technology. We are continuing to provide support and research and development. However, many problems remain to be solved in order to supply and settle smart farms in Korea. The purpose of this study is to provide a method of collecting and sharing data on farming environment and to help improve the income and productivity of farmers based on collected data. In the case of hog farm, the multiple sensors for environmental data like temperature, humidity and gases and the network environment for connecting the internet were established. The environment sensor was made using the ESP8266 Node MCU board as micro-controller, DHT22 sensor for temperature and humidity, and MQ series sensors for various gases in the hog pens. The network sensor was applied experimentally for one month and the environmental data of the hog farm was stored on a web database. This study is expected to raise the importance of collecting and managing the agricultural and environmental data, for the next generation farmers to understand the smart farm more easily and to try it by themselves.

Up-to-date statistics of crop cultivation status is essential for farm land management planning and the advancement in remote sensing technology allows for rapid update of farming information. The objective of this study was to develop a classification model of rice paddy or winter crop fields based on NDWI, NDVI, and HSV indices using Sentinel-2 satellite images. The 18 locations in central Korea were selected as target areas and photographed once for each during summer and winter with a eBee drone to identify ground truth crop cultivation. The NDWI was used to classify summer paddy fields, while the NDVI and HSV were used and compared in identification of winter crop cultivation areas. The summer paddy field classification with the criteria of -0.195

In this study, we constructed a process simulation model for an agricultural by-products based Solid Oxide Fuel Cell (SOFC) combined heat and power generation system as part of the introduction of technology for energy self-sufficiency in the agricultural sector. The aim was to reduce the burden of increasing fuel and electricity consumption due to rapid fluctuations in international oil prices and the expansion of smart farming in domestic farms, while contributing to the national greenhouse gas reduction goals. Based on the experimental results of 0.3 ton/day torrefied agricultural by-product gasification experiment, a model for an agricultural by-product-based SOFC cogeneration system was constructed, and optimization of the heat exchange network was conducted for SOFC capacities ranging from 4 to 20 kW. The results indicated that an 8 kW agricultural by-product-based SOFC cogeneration system was optimal under the current system conditions. It is anticipated that these research findings can serve as foundational data for future commercial facility design.

As a first step in obtaining the minimum level of data needed to develop smart cultivation technology for Korean seaweed gim (Pyropia yezoensis), farming tests have been carried out using onshore aquaculture facilities. The aquaculture facility was built on paddy farmland on the west coast of Chungnam and received seawater from nearby sea. In this paper, we report the overall process and results of the aquaculture trials attempted in Korea's first onshore gim aquaculture facilities. In addition, the industrial possibility of gim production using the onshore aquaculture system will be discussed through the analysis of all expenses incurred in the test form.

Recently, there are growing fluctuations of productivity and price caused by severe weather conditions in the agriculture. Yield forecasting methods have been studied to solve the problems. This paper predicted yield per area, production area, and elements of weather based on the linear equation. A yield is calculated by multiplying the production area times the yield per area that is compensated using the weighted sum of the elements of weather. In experiments, proposed method shows that a forecasting precision is the more than 90%.

도시 농업은 도시 과밀로 인한 긴장을 완화시키고 환경과 생태 보전, 경관을 아름답게 꾸미고 색다른 도시문화 형성에 기여도 할 수 있는 다원적인 기능을 제공한다. IT분야에서는 비닐하우스나 옥상녹화 등의 다양한 도시녹화 분야에서 솔루션들을 제공하게 되는데, 규모에 따라 다르지만, 비용이 많이 들어간다는 단점을 가지게 된다. 본 논문에서는 SNS 플랫폼을 저비용의 관리 플랫폼으로 활용할 뿐 아니라 사람들이 텃밭이나 옥상 정원을 통해 공감할 수 있도록 해주는 스마트 농장 관리 시스템을 설계하고 구현하였다.
