A transmission designed with P.T.O(Power Take-Off) axle for agricultural work vehicles including multi-purpose vehicles has been developed. It is focused on the 4-wheel drive transmission of synchronous contact type for practical use in fruit tree households which is required for a large-sized agricultural vehicle. Concerning to the specification performed, the load capacity is from 500kg to 1,000kg and the safety should be secured for passengers. In addition, the driving condition should also be secured under bad situations of the topographic slope, swampy land and the rest. In order to carry out above tests, a prototype vehicle through strength analysis of transmission design has been manufactured. Consequently, optimal design conditions on the power transmission with multi-purpose vehicle for various jobs are proposed such as an indication of optimal RPM and torque at a certain work situation. The performance test through the prototype of multi-purpose work vehicle is performed and the related data base is achieved. Finally, it is improved on troubles by the analysis of the results of R&D and provided the solutions on problems occurring to mass production in the future.

This study compared the pattern of couples' time-use in rural areas. Wives' and husbands' time spent in household work, leisure, and agricultural labor were compared. In addition, this study examined what factors determine the amount of time of couples spent in such activities. According to the results, in general, the pattern of couple's time-use in rural area was different. Regarding the pattern of time-use, three major results could be mentioned. First of all, husband in rural area spent most agricultural labour time in busy farming season. And then husband spent much time in leisure activities and wife spent in household work. Second, wife spent more time in inactive leisure and husband spent more time in active leisure. Third, husband in rural area spent less time in household work. In particular. they spent less time in female-typed work than male-typed work. To examine what factors determine the extent of time spent in such activities, three theories were employed and tested. According to the results, the models employed in this study were realistic in explaining the amount of time of couple in rural area, and more adjustable wife than husband. In conclusion, a combination of the multidimensional theoretical perspectives used in this study helpfully explains the variation in the amount of time-use of couple in rural area.

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.

It is said that robot can be used for multi-purpose use by changing end effector or/and visual sensor with its software. In this study, it was investigated what multi-purpose robot for fruit-production was using a tomato harvesting robot and a robot to work in vineyard. Tomato harvesting robot consisted of manipulator, end-effector, visual sensor and traveling device. Plant training system of larger size tomato is similar with that of cherry-tomato. Two end-effectors were prepared for larger size tomato and cherry-tomato fruit harvesting operations, while the res components were not changed for the different work objects. A color TV camera could be used for the both work objects, however fruit detecting algorithm and extracted features from image should be changed. As for the grape-robot , several end-effector for harvesting , berry thinning , bagging and spraying were developed and experimented after attaching each end-effector to manipulator end. The manipulator was a polar coordinate type and had five degrees of freedom so that it could have enough working space for the operations. It was observed that visual sensor was necessary for harvesting, bagging and berry-thinning operations and that spraying operation requires another sensor for keeping certain distance between trellis and end-effector. From the experimental results, it was considered that multi-operations by the same robot could be appropriately done on the same or similar plant training system changing some robot components . One of the important results on having function of multi-operation was to be able to make working period of the robot longer.

This study was conducted to investigate the perception and understanding parents had regarding environment friendly agricultural products being used for school foodservice. A trained practitioner surveyed 221 parents of children at elementary schools in Daejeon using a questionnaire, after which the resulting data were analyzed by a Chi-square test. Overall, the parent's responses regarding the foodservice were positive. However, most of the parents do not participate (65%) in the school foodservice if they work, and those that do participate primarily work as meal service aides (58.1%). Parents indicated that the work of urgent field of inspection on food materials (69.9%), and the reason of an agreement (98.2%) for them were the students' health (68.4%). In addition, most parents were positive about the possibility of replacing foods used in the school with environment friendly products (51.6%) and felt that the government should pay the additional expense associated with their replacement. Furthermore, the majority of the parent's surveyed felt that children should be supplied with vegetables (54.9%) purchased directly from farms. The parents' satisfaction with the meal service (25.1%) was lower than that of the students (54.1%). The reason for the satisfaction reported by the parents was concern regarding the health of their children (53.3%). In addition, the majority of the parents (47.3%) responded that environment friendly agricultural products differ from general agricultural products because insecticides and fertilizer were not used. The main objection parents had to using environment friendly products was their cost (59.1%), and most parents felt that a realistic solution to this problem was unified purchase (41.4%). Besides, a problem when replacing with them was the expensive price (38.1%) and true or false (37.7%), and the students' satisfaction (59.5%) was selected the most in an effect of using them, diversity of the product (39.1%) and price reduction (32.6%) for a solution of the increase of using them.

The purpose of this study was to analyze the structure of time use by housewives in rural households, and to compare the time use structure of housewives with that of their husbands. To attain this goals, we have selected 108 farmhouses considering agricultural area and size in L993. Data was collected by observing how (i. e., doing what kinds of work) housewives and husbands spend time, Time use was divided into four categories : physiological time, socio-cultural time, household work time and agricultural labor time. The results in this study present a valuable insight to assuage the overloaded works of rural housewives. The major results can be outlined as follows : 1. Rural housewives worked 1.2 times longer hours a day than their husbands did. 2, There existed a severe labour time imbalance between housewives and husbands during the busy farming season. 3. The time use patterns of housewives and husbands were significantly different across agricultural areas. Also, the education level of a housewife was associated with the length of her labor time.

In this paper, we have developed a multi-attitude monitoring system for running farm robots for field farming. There are many agricultural robots that can select work modules for various tasks. In order to control the stable attitude of agricultural robots connected to each other, we developed a system for monitoring the roll angle and pitch angle difference by fusing the information of the attitude monitoring system mounted on the robot mainframe and the work module. The developed attitude monitoring system showed resolution below 1 degree. In this paper, roll angle difference of 20 degrees and 60 degrees is measured with a multi - attitude monitoring system.
