ジャーナル フリー1. For the investigation of the changes of the time requirements for the work and the rest during the works and the individual differences of these requirements among workers, the time studies were carried out on the about 6, 4 and 2 hour's works of the plant singling by the traditional method in turnip fields.
2. The time requirements for the works, the walking speeds in the works and the time ratios of rest to work were influenced considerably by the conditions of fields and plants and the mental states of the workers, and were different among the workers especially in short time works.
3. The workers in their fifties were larger in the time requirements for the works, slower in the walking speeds and lower in the time ratios of rest to work than the younger workers.
4. When the workers did not make haste psycologically with their works, the ratios of rest to work increased in proportion to the work time elasped and the coefficient of correlation between the walking speeds and the time ratios of rest to work was highly significant among workers.
5. When they made haste psycologically with their works, the workers in their fifties accomplished it by lowering the time ratio of rest to work, and the younger workers by walking faster.
6. The averge time requirement for the singing work was 19.3min. per are including rest time and 13.6min. per are excluding rest time.
It was assumed that the difference of the time requirment to previous article was principally resulted from the difference of the degree of the precision in singling.抄録全体を表示PDF形式でダウンロード (987K) -

ジャーナル フリー1. For comparing the time requirements of the plants singling works in the traditional method and the platform method, the survey on the work diaries and the time studies on singling works were carried out in turnip fields.
2. From the results of the survey on the work diaries, it was comfirmed that the most labour saving work sequence was “drilling in row-brocking the row-singling by hands” and the time requirement for singling was about one hour per are in the traditional method and 17-24min. per are in the platform method.
3. From the results of the time studies, the time requirement for singling by the platform method was 14.8min. per are including tractor operater. As the time requirement for singling by the traditional method was 13.6min. per are in the previous article, the difference of the time requirement between both method was not perceived so far as the results of the time studies was concerned.
4. The discrepancy of the results between the survey on the work diaries and the time studies was discussed on the accuracy of the records, the effects of the time studies on the workers and the difference of the work load, and it was assumed conclusively that the time requirement by the platform method was smaller than that by the traditional method.
5. From the comparison of the work contents of both methods, it was conclued that the platform method was supreior to the traditional method from the view point of the time requirements, the work planning and the work loads on the workers.抄録全体を表示PDF形式でダウンロード (853K) -
