여름철 비닐 하우스 오이 수확 농민의 작업 부담 및 온열 환경 평가 = Evaluation of the Farmers' Workload and Thermal Environments during Cucumber Harvest in the Greenhouse

다국어 초록 (Multilingual Abstract)

Physiological and subjective responses and work postures of the farmers and thermal environment during cucumber harvest in the greenhouse were investigated to evaluate the thermal environments and farmers' workload. Five career farmers (1 female, 4 males) volunteered as subjects. Farmers' work was monitored continuously for two days without any disturbance. The results were as follows. 1) Air temperature (Ta), air humidity (Ha), globe temperature (Tg) and WBGT for two days were mean 29~32℃, 70~81%RH, 30.3~44.5℃ and 27.6~32.9℃, respectively. By the WBGT, we evaluated that the thermal environment in the greenhouse gave a thermal burden to farmers. 2) The range of total work time was 161~298 minutes. The percentage of the work postures during the cucumber harvest was larger in order of sitting, standing and walking. 3) Rectal temperature (Tre) and mean skin temperature (Tsk) were 37.2(± 0.3)℃ and 33.2(±0.9)℃. Clothing microclimate temperature (Tel) on the chest and the back were 32.0(±0.8)℃ and 34.3(± 1.5)℃ (p ＜ 0.(01). Clothing microclimate humidity (Hcl) was over 75%RH. Heart rate (HR) was 92(± 13) bpm and energy expenditure was 210(±43) kcal/hr. We evaluated that the harvesting cucumbers in the greenhouse was 'moderate work' by the physiological responses. 4) Average subjective responses of the farmers were 'somewhat hard", 'hot', 'very humid' and 'a little uncomfortable'. It is suggested that administrators should be concerned about the development and supply of portable cooling equipment as well as the improvements of working environment to alleviate farmers' heat strain and work load in summer.
