项目摘要

This research discusses the factor analyses of forest labor accidents. The Japanese forestry is one of industries in which forest workers have met with most of accidents. It was very difficult to gather many samples of the existing labor accidents for analyzing them, because they related to the labor's privacy. However, we could collect the samples of 5,558 in total. Numbers of these samples were satisfactory to statistical analysis. The analyses were done three investigating groups to national forest , private forest and experiment forest occupied by universities. From these analyses, the followings were drawn: (1) The aging of forest workers were seen generally in site, and it was seen that the labor accidents focussed much more on 50 years old. However, this is not equal to easyly suffer the accidents in 50 years old, because most of forest workers were occupied by the aged persons. (2) Most of labor accidents focussed on the operations with tools and portable machines, because there are a lot of unsafe situation in working site in forestry. (3) If the operation is continued by lower level technics the safety education for workers must be repeately and repeately practiced to decrease accidents in site. If possible, it was justified that the use of higher level technics was effective in decreasing accidents. (4) We have a cerebral rhythm in a day. Namely, it was seen from analyses that it was repeated its rhythm rose and went down. Labor accidents particuraryly occured easely under later condition. To decrease labor accidents it is important to take into consideration the cerebral rhythm.

本研究探讨了森林劳动事故的因素分析。日本林业是林业工人遭遇事故最多的行业之一。现有的劳动事故很难收集到大量的样本进行分析，因为这些样本涉及到劳动者的隐私。但是，我们总共可以收集到5，558个样本。这些样本的数量符合统计学分析。对国有林、私有林和高校占用的实验林进行了三个调查组的调查分析。结果表明：（1）现场林工普遍老龄化，劳动事故集中在50岁以上。然而，这并不等于50岁以后就容易发生事故，因为林业工人大多数是老年人。(2)林业作业现场存在着大量的不安全因素，劳动事故主要集中在使用工具和轻便机械的作业中。(3)如果是由低级工艺人员继续作业，则必须对工人进行反复的安全教育，以减少现场事故的发生。在可能的情况下，采用更高水平的工艺是减少事故的有效方法。(4)我们一天之内会有脑节律。即从分析中可以看出，它是重复的，节奏上升和下降。特别是在后期条件下，更容易发生劳动事故。为了减少劳动事故，重要的是要考虑到脑节律。
