  • Objective: The objective this paper is to introduce the agricultural ergonomics and to show the importance of it in improving the agricultural works. Background: Despite of rapid advancement of technologies and adoption of modern mechanical equipments at farms in Korea, most of agricultural works have still remained manual and thus have regarded as one of the hardest works. With aging and feminization in rural areas, the need to improve agricultural works has grown quite much. Agricultural ergonomics have been known as a good tool in improving agricultural works around the world. Recently Korean government initiated a national program of providing assistive equipments to help farmers and a few ergonomists started to apply agricultural ergonomics in our rural villages as a part of this program. Method: This study reviewed how Ergonomics was used for the agricultural work. Results: Methods of Ergonomics which are used for the agricultural ergonomics and the simple procedure of the agricultural ergonomics were presented. Conclusion: It was found that agricultural works can be improved quite much using the agricultural ergonomics principle and the musculoskeletal stress of farmers can be reduced significantly.

  • Objective: This study aims to analyze qualitatively if PTS methods are applicable to the agricultural works of Korea. Background: Many studies on setting standard time have been performed for manufacturing and service industries, not many studies on agricultural work have been carried out domestically and internationally. Method: MTM, MOST, Work Factor, MODAPTS were applied to some agricultural works, and limitations of each method were found out. Results: MTM was found to be more applicable than other methods, except for mental works. Conclusion: In general, many Korean agricultural works need squat postures, which are not taken into account in most of PTS methods. Continuous observation with stop watch is recommended for establishing the standard time for the agricultural works of Korea. Application: The information drawn from this study would be helpful to the farmer safety assurance system being established by Korean government.

  • 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.

  • 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 Sea dike tidal closure works has traditionally ended in the failure. Therefore, the success of the tidal closure in Hwaong in the sea near Inchon where has the greatest tidal gap in our country deserves to consider its meaning. While its process was going on, we had the difficulty like bad weather, unexpected ground settlement, flow velocity beyond the imagine, etc. Moreover, environment group's rush was so fierce that the works could have been delayed. This works showed that not only technical aspects but also social problems(environment group's rush and public discontents) were important factors in accomplishing the works. Finally, all of the difficulties were overcome and the tidal closure works were successful. So, This success is the best example in a kind of the another works in itself.

  • Recently, there has been the gradual growth of the public in rural amenities, hobby farming works, much more urbanities, and especially near-retires. However, in spite of popular preference to ruralities, little has been known about their demand on retired rural life. Therefore, this study examined urbanites' attitude to preparatory works for out-migration, preferred residential site condition and life styles in the countryside. For the purpose, data were collected from the survey with the sample of 62 urban trainees who were studying farming technology in department of training on agricultural technology of Korea National Agricultural College, RDA. We carried out the experience farming to candidate with using the abandoned sericultural facilities which are the silkworm rearing house and mulberry fields. The 71% of urban trainees, who answered in this survey, hoped to move into countryside after retirement and to make a monthly income of $1,000 from agriculture. The age distribution of sericulural farmers is about 79% more than that of 60 years old. In the experience farming works. The two candidates made 1,977$ with net income through 32 days worked in spring season. In autumn season, the couple candidates made 1,317$ with net income through 23 days worked. Knowledge of these results will be important to policy-makers and to understand the role that retirement in-migration play in stimulating economic growth of rural agricultural farmers.

  • 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.

  • Objective: The aim of this study was to develop an ergonomic checklist (AULA: Agricultural Upper-Limb Assessment) which can assess the risks of the work-related upper limb disorders of farming tasks in Korea. Background: There are few assessment tools that reflect the current condition of agricultural works as of now. Method: AULA was developed as following three stages. First of all, a physiological experiment was conducted with selected 14 upper limb postures which are frequently occurred in farming tasks and then, an ergonomic checklist was developed with determining risk levels of each body posture based on the experimental findings. Lastly, the ergonomic checklist was validated by comparing with the existing assessment tools. Results: When comparing the AULA which was developed in this study with the existing assessment tools, it was found that the AULA may get over limits of the existing ones which are sensitive to particular postures, but aren't sensitive to the rest of them. Conclusion: It is predicted that the developed upper limb posture assessment tool which gets over the existing tools' limits and is proper for domestic farm work conditions, will help to reduce musculoskeletal disorders caused by farm works, by assessing farm works more easily and objectively. Application: By further developing the theoretical groundwork on the induction of muscular skeletal system symptoms relating to agricultural works, it is expected to improve the level of preventing and managing such muscular skeletal system symptoms in the field of agricultural and farming works, which is relatively less advanced in terms of labor difficulties.
