Study on Large Power Tractor Driver’s Heart Rate and Fatigue in Sowing Work

In order to reduce the driving fatigue in sowing work, this paper based on heart rate (HR) as the main indicator to survey, tested and analyzed the fatigue condition of the drivers of three imported tractors and one domestic tractor in sowing work. The results showed that when driving the imported tractors in sowing work, the HR increasing rate was 10.4%-14.3%, labor intensity belonged to the light level;when driving domestic tractor in sowing work, the HR increasing rate was 23.4%-33.0%, it was remarkably bigger than that of driving imported tractors (P＜0.05), labor intensity belonged to the middle level. The main effects on driving fatigue included the control methods, tractors' cab environment, processing time, operating content, and so on. Finally, we proposed the concrete measures and suggestions to reduce driving fatigue and improve drivers' work condition.     

Employment

The 1990s began with unprecedented market conditions for labour: unemployment rates were reaching their highest level in over 50 years, participation in the labour market had fallen to historically low levels and net emigration was widespread across all occupations. It seemed that things could only get better. While some did benefit from the limited growth that took place in the nineties, many did not. The greater inequality generated during the 1980s was fanned by the deregulation of the labour market and remained undiminished throughout the following decade. The marked reduction in manufacturing employment in the 1980s continued into the early 1990s negatively impacting Maori and Pacific Island men and women in particular. Increasingly post‐secondary school education became necessary to gain entry into regular work and those with little formal education and few work skills fell further down the queue. These changes are closely allied to the processes of globalisation which is already exercising considerable influence on the employment opportunities of New Zealanders.
