Özet:

 Inappropriate working postures in work life cause musculoskeletal disorders in various body parts of employees such as back, arm, neck and wrists. In order to prevent the occurrence of these discomforts, it is necessary to determine risk levels through ergonomic risk assessments and develop improvement suggestions. In this study, it was aimed to analyze the correlations between the ergonomic risk scores obtained using ergonomic risk assessment methods and the amount of energy consumption of the operations in the production department of an enterprise that produces metal parts. In the enterprise, risk scores were determined using REBA, QEC, OWAS and MURI methods for 20 operations by the workers themselves. In order to determine the amount of energy consumed by the worker during the operation, a HUAWEI Watch Fit model smart watch was attached to the worker, and the total amount of energy spent for 120 minutes, and average heart rate values were recorded. Risk scores were determined between 4-8 for REBA, 65-77 for QEC, 1-2 for OWAS and 10-15 for MURI. Total energy amount is between 292-532 Kcal and the average heart rate is between 78-103. Correlations between risk scores and amount of energy spent were 0,46 for REBA, 0,20 for QEC, -0,07 for OWAS and -0,12 for MURI.

 İş yaşamında uygun olmayan çalışma duruşları, çalışanların sırt, kol, boyun, bilek gibi muhtelif vücut bölgelerinde kas iskelet sistemi rahatsızlıklarına neden olmaktadır. Böyle rahatsızlıkların ortaya çıkmasını engellemek amacıyla, ergonomik risk değerlendirmeleri ile risk düzeylerinin tespiti ve rahatsızlıkları azaltıcı iyileştirme önerilerinin geliştirilmesi gerekmektedir. Bu çalışmada, metal parçaların üretimini gerçekleştiren bir işletmenin üretim bölümündeki işlemlerin ergonomik risk değerlendirme yöntemleri kullanılarak elde edilen ergonomik risk skorları ile enerji tüketim miktarı arasındaki korelasyonların analizi amaçlanmıştır. İşletmede, bizzat işçilerin yapmış oldukları 20 işlem için REBA, QEC, OWAS ve MURI yöntemleri ile risk skorları tespit edilmiştir. İşlemleri yapan işçinin işlem boyunca harcadığı enerji miktarının tespiti için HUAWEI Watch Fit model akıllı saat çalışana takılarak, 120 dk boyunca harcadığı toplam enerji miktarı ile ortalama kalp atış frekansı değerleri kaydedilmiştir. Risk skorları; REBA için 4-8, QEC için 65-77, OWAS için 1-2 ve MURI için 10-15 arasında tespit edilmiştir. Toplam enerji miktarları 292 - 532 Kcal ve kalp atış frekansı ortalaması ise 78 - 103 aralığındadır. Risk skorları ile harcanan enerji miktarı arasındaki korelasyonlar; REBA için 0,46, QEC için 0,2, OWAS için -0,07 ve MURI için -0,12 elde edilmiştir.
