As agricultural companies encounter number of risks in their business, it is very important to control the risks for their stable management. So we examine the agricultural business risks and propose the risk management strategies for the agricultural companies. For these purpose, we analyze the agricultural business risks with which agricultural companies are confronted, and propose the agricultural companies' the risk management strategies. The results of this study are as follows : First, Changing the risk environment of agricultural business, we have to realize the importance of the agricultural risks and risk management in it. Second, When we choose the risk management strategies which are risk retention, risk avoidance, risk control, risk transfer and insurance, etc., we should always consider the frequency of loss and the severity of loss. Third, If we don't control the agricultural risks, we will be in a position to very difficult situation. So, Agricultural companies should lead to stronger effort to manage the risks for their stable business.

The accident risk at the construction workplace associated with agricultural engineering is comparatively higher than those of other fields due mainly to its complex work types and processes. Agricultural engineering deals with a variety of agricultural infrastructures from irrigation and drainage facilities to giant-scale coastal reclamation land infrastructures. The characteristics that most agricultural projects have conducted on a small-scale even worsen the situation drawing low attentions to risk management. Therefore, systematical risk assessment that focuses on details of agricultural construction work process is required in order to enhance safety management capacity and to prevent repetitive accidents ultimately. This study aims to categorize construction work types and processes of agricultural construction works, and to quantitatively assess the accident risk of them based on accident analysis. Regarding classification of construction works, actual 827 accident cases were thoroughly reviewed and coded by their construction site, facility and work type, project scale and so on. Most accidents (71.8 % of total cases) occurred in small-scale construction workplaces with less than 5 billion Korean won project budget. And those accidents related to agricultural infrastructure project (37.4%) and agricultural water development project (22.4%). In terms of work types, accidents frequently took place in form-work followed by pipe installation work, steel bar work and concrete work. The potential risks were compared with actual outbreak of accidents based on Analytic Hierarchy Process (AHP). The results show that the potential conditions of accident expected to be took place is somewhat different from the actual conditions where accidents actually happened. This implicates that risk management manuals or education needs to be adjusted by reflecting unexpected circumstances. Overall, this study is meaningful in that the results could be foundations as to strengthen risk management capacity for agricultural engineering projects.

Drought risk assessment is usually performed qualitatively and quantitatively depending on the definition a drought. The meteorological drought indices have a limit of not being able to consider the hydrological components such as evapotranspiration, soil moisture and runoff, because it does not consider the water demand in paddies and water supply in reservoirs. Agricultural drought was defined as the reservoir storage shortage state that cannot satisfy water requirement from the paddy fields. The objectives of this study were to suggest improved agricultural drought risk assessment in order to evaluate of regional drought vulnerability and severity studied by using Reservoir Drought Index (RDI). The RDI is designed to simulate daily water balance between available water from agricultural reservoir and water requirement in paddies and is calculated with a frequency analysis of monthly water deficit based on water demand and water supply condition. The results indicated that RDI can be used to assess regional drought risk in agricultural perspective by comparing with the historical records of drought in 2012. It can be concluded that the RDI obtained good performance to reflect the historical drought events for both spatially and temporally. In addition, RDI is expected to contribute to determine the exact situation on the current drought condition for evaluating regional drought risk and to assist the effective drought-related decision making.

This study has systematically classified established the agricultural management risks from the agricultural company's position and analyzed their counterplan situation in order to seek measures to counteract this. The AHP & IPA technique were used as an analysis method concerning the evaluation results. The counterplan situation was deduced through an interview investigation of 112 farmers who produce cabbage, white radish, onion, garlic, chili, and 6 other such items in order to stereotype the risks. If the agricultural companies' management capacity is raised in accordance to the risk counterplan deduced from this study, and the risks of agricultural management activity are avoided ahead of time or counter means are activated, we can anticipate the stabilization of agricultural management.

Objective: A method to assess the risk level of agricultural works considering work posture and working time was suggested, and the method was applied to the major fruit crops. Background: It is not complete to analyze only work postures when assessing risk level of agricultural works. Method: $3{\times}3$ matrix was employed, in which the severity level was taken from the REBA method and exposure level was taken from the working time, using the criteria of caution zone/hazard zone. Results: Among the 5 major fruit crops(apple, pear, grape, peach, persimmon), the highest level of ergonomic risk was found in the apple and pear, while medium level was found in other 3 crops, mainly because the working time was less in the 3 crops. Conclusion: It was found that when assessing the overall ergonomic risk of agricultural works, work posture and working time should be considered at the same time. Application: The suggested method could be applied to other non-cyclic tasks.

The objective of this study is to estimate the relationship among perceived value, perceived risk, satisfaction, purchase intention for environmental-friendly agricultural products. For this, we separate consumer with two groups that one is the experienced, the other is the not-experienced. Four factors is respectively adopted in perceived value and risk with exploratory and confirmatory factor analysis. The results of this study show that emphasizing the value of environmental-friendly agricultural products is important to the not-experienced. And to decease the risk is more effective to the experienced for activating market.

형질전환작물 상업화의 최종 규제단계는 위해성심사와 품종출원이다. 위해성심사를 위한 형질전환작물의 위해성 평가는 광범위한 과학자 네트워크, 고비용과 오랜 기간을 필요로 한다. 따라서 형질전환작물 개발자는 우수한 형질의 개발 이외에 위해성평가에 대한 이론적 및 전략적 측면을 부가적으로 고려해야 한다. 유전자변형생물체의 위해성평가에 대한 일반적인 개념은 화학물 위해성평가로부터 유래하였다. 그러나 생물체가 가지는 복잡성 때문에 실질적동등성과 친숙성으로 대표되는 비교접근 방법이 개발되어 왔다. 실제적인 측면에서 통합적인 위해성평가는 유전자이동성, 독성과 알레르기와 같은 개별 위해성평가보다 더 어렵다. 형질전환 계통의 품종출원을 위해서는 위해성평가 단계에서부터 품종보호요건을 고려한 평가자료 생산과 위해성 심사 승인 계통을 이용한 다양한 LMO 품종 육종전략이 필요하다.

Because reservoirs that supply irrigation water play an important role in water resource management, it is necessary to evaluate the vulnerability of this particular water supply resource. The purpose of this study is to provide water supply risk maps of agricultural reservoirs in South Korea using irrigation vulnerability model and cluster analysis. To quantify water supply risk, irrigation vulnerability indices are estimated to evaluate the performance of the water supply on the agricultural reservoir system using a probability theory and reliability analysis. First, the irrigation vulnerability probabilities of 1,346 reservoirs managed by Korea Rural Community Corporation (KRC) were analyzed using meteorological data on 54 meteorological stations over the past 30 years (1981-2010). Second, using the K-mean method of non-hierarchical cluster analysis and pre-simulation approach, cluster analysis was applied to classify into three groups for characterizing irrigation vulnerability in reservoirs. The morphology index, watershed area, irrigated area, and ratio between watershed and irrigated area are selected as the clustering analysis parameters. It is suggested that the water supply risk map be utilized as a basis for the establishment of risk management measures, and could provide effective information for a reasonable decision making on drought risk mitigation.

The purpose of the farmstead-specific early warning service system for weather risk management is to develop custom-made risk management recommendations for individual farms threatened by climate change and its variability. This system quantifies weather conditions into a "weather risk index" that is customized to crop and its growth stage. When the risk reaches the stage where it can cause any damage to the crops, the system is activated and the corresponding warning messages are delivered to the farmer's mobile phone. The messages are sent with proper recommendations that farmers can utilize to protect their crops against potential damage. Currently, the technology necessary to make the warning system more practical has been developed, including technology for forecasting real-time weather conditions, scaling down of weather data to the individual farm level and risk assessments of specific crops. Furthermore, the scientific know-how has already been integrated into a web-based warning system (http://new.agmet.kr). The system is provided to volunteer farmers with direct, one-on-one weather data and disaster warnings along with relevant recommendations. In 2016, an operational system was established in a rural catchment ($1,500km^2$) in the Seomjin river basin.

Farmers are generally expressed to pesticides through mixing loding, application activity and harvesting of crop after application of pesticides. The present work investigated the exposure and risk of furathiocarb to workers when harvesting of cucumber was carried out in green house after application of furathiocarb EC. Glove was used for the hand exposure assessment, socks for foot and dermal patches for the other parts of body. Personal air monitor equipped with a XAD-2 resin was used for the respiratory exposure assessment. During the harvest of cucumber in green house, the initial rate of potential dermal exposure (Day 1) for methidathion was 1.3 mg/hr. The major exposure parts were hand $(78\~83\%),\;thigh\;(5\~7\%)$ and arms $(6\~9\%)$ during 3 days' harvest. No exposure was detected from the respiratory monitoring. For risk assessment, the potential dermal exposure (PDE), the absorbable quantity of exposure (AQE) and the margin of safety (MOS) and margin of exposure (MOE) were calculated. In risk assessment of harvester exposure for 7days, all MOS was > 1 and MOE was > 100 indicating that possibility of risk was little.
