Abstract

ABSTRACT Larix kaempferi (Lamb.) Carr. plantations are a reasonable alternative to timber production for producing high-quality wood for South Korean industrial applications that need appropriate and high-quality practice of silvicultural operations. Weeding and tree pruning operations, which can favor trees in their competition with vegetation, require intensive manual labor. Therefore, the objective of this study was to determine the effect of these operations on the heart rate variability, relative heart rate (RHR), and physical workload of workers in April (spring) and July (summer) months. Our results showed that the mean heart rate variability and RHR for weeding (108.0 bpm and 49.4%, and 105.8 bpm and 46.8% for worker A and B, respectively) and tree pruning (104.5 bpm and 46.1%, and 114.4 bpm and 55.9% for worker A and B, respectively) in July were higher than those in April. In addition, the level of workload in July was characterized as heavy to very heavy, and as moderate to heavy in April. The results from this study provide useful information for appropriate young tree tending operations from the perspective of the safety and health of workers.

季节对日本落叶松幼树抚育作业工人心率变异性和工作量的影响卡尔。立场:初步研究

摘要山柰。种植园是木材生产的合理替代品，为韩国工业应用生产高质量的木材，这些工业应用需要适当和高质量的造林操作实践。除草和修剪树木的操作可能有利于树木与植被的竞争，需要密集的体力劳动。因此，本研究的目的是确定这些手术对4月（春季）和7月（夏季）工人心率变异性、相对心率（RHR）和体力工作量的影响。我们的结果显示，7月份除草（工人A和B分别为108.0 bpm和49.4%，105.8 bpm和46.8%）和修剪树木（工人A、B分别为104.5 bpm和4.61%，114.4 bpm和55.9%）的平均心率变异性和RHR高于4月份。此外，7月份的工作量从繁重到非常繁重，4月份为中度到重度。从工人的安全和健康角度来看，这项研究的结果为适当的幼树抚育作业提供了有用的信息。
