Atkos, Istvan.
Az elvégzett értékelés alátámasztja a szakirodalmakban is olvasható véleményeket, miszerint ma már csak a kényelmes fekhelyű színszerű istállókban, kötetlenül tartott és magas fokon automatizált fejőállásokban fejt állományokkal van esély a versenyképes, fenntartható tejtermelésre, feltételezve természetesen a korszerű fajtát és az igényes takarmányozást. Ennek a tartás-1 és üzemeltetés-technológiai2 korszerűségi követelménynek csak a színszerű istállóban, almozott kötetlen tartás és a színszerű istállókban almozatlan kötetlen tartás tudnak eleget tenni. Közülük az alommentes változat – amellyel elsősorban a prognosztizált klímaváltozás miatt kell foglalkozni – még további vizsgálatokat is kíván. Építési, hőszigetelési, klimatizálási és üzemeltetési...

A strategy for workplace health promotion on German dairy farms CIGR Journal
Jakob, Martina Carola; Thinius, Maxi.
Studies across the globe have shown that at least 3 out of 5 milkers experience pain in the musculoskeletal system (MSS), mostly in the upper extremities (DOUPHRATE et al., 2014, JAKOB, 2011, KOLSTRUP, 2012, PINZKE, 2003, TUURE & ALASUUTARI, 2009, KAUKE et al., 2010, THINIUS, 2012). The World Health Organisation (WHO) defines health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. It is well known that dairy farming, and milking in particular is coupled with several risk factors for developing musculoskeletal disorders (KOLSTRUP, 2012). Technical measures seem to be insufficient to avoid physical overload. Therefore a more comprehensive approach seems to be necessary. In this study, four...

Discovering the physical onerous activities in manual sesame grain harvest using postural analysis CIGR Journal
Hayati, Abdullah; Marzban, Afshin; Leylizadeh, Masoud.
The sesame oil is accounted as high-priced and high-quality oil, but its production is less than that of major oilseeds due to labor-intensive harvest similar to many agricultural activities. These types of activities are often onerous leading the workers to occupational risk factors such as musculoskeletal disorders. Thus, the aim of this study was to evaluate the manual sesame grain harvest (consisting of work tasks of mowing, tying and shaking) regarding postural workloads to identify onerous activities during this operation which would help to mitigate some problems of the sesame grain production chain. Ovako Working posture Analysis System (OWAS) was used for working posture analysis of twenty-six male workers employed for this study. Results showed...

Effect of Job Rotation on the Risk of Developing Ul-WMSDS in Poultry Slaughterhouse Workers Rev. Bras. Ciênc. Avic.
Dias,NF; Tirloni,AS; Reis,DC; Moro,ARP.
ABSTRACT This study analyzed the effect of job rotation on the risk of developing UL-WMSDs in a poultry slaughterhouse with 1,200 workers. Three organizational settings were evaluated (“without job rotation”, “with job rotation - tasks >1h” and “with job rotation - tasks <1h”) using the OCRA Checklist method and the fulfillment of requirements for the implementation of rotations established by the Brazilian Regulatory Standard NR-36. The OCRA score of the right upper limbs (16.5±5.7) were significantly higher (p<0.001) relative to the left upper limbs (15.0±5.6). The average scores on all three organizational conditions presented moderate risk. There was a significant difference between the scores of the conditions “without job rotation” and “with...

Knapsack sprayers: effort required for pumping lever operation Ciência Rural
Lambrecht,Edson; Rosa,Douglas Silva da; Machado,Roberto Lilles Tavares; Machado,Antônio Lilles Tavares; Reis,Ângelo Vieira dos.
ABSTRACT: Various equipment, mainly manual knapsack sprayers, are used to apply agrochemicals by smallholder farmers. They are highlighted by their versatility of use and mainly by their low cost for farmers. Few operator-related studies were reported in the literature regarding the effort required to operate the knapsack sprayer lever. Knapsack sprayers were evaluated regarding the effort required to move their hand levers, reach and maintain the 300 kPa pressure, and return to the initial position. The objective of this study was to evaluate the operator’s effort to operate the hand lever using the “Super magro” biofertilizer as fluid. It was concluded that all knapsack sprayers are within the Consolidation of Labor Laws (CLT) standards regarding the...
