Recently the concept of facility efficiency, which defined by data envelopment analysis (DEA), introduced as a location modeling objective, that provides facilities location’s effect on their performance in serving demands. By combining the DEA models with the location problem, two types of “efficiencies” are optimized: spatial efficiency which measured by finding the least cost location and al...

Effects of an office ergonomics workplace and training intervention on workers' knowledge and self-reported musculoskeletal pain and discomfort were investigated. An instructional systems design process was used to develop an office ergonomics training program and the evaluation tools used to measure the effectiveness of the training program on workers' office ergonomics knowledge and skills. I...

Ergonomics as a discipline was in the past, is in the present, and will be in the future, an integrating constituent in occupational safety and health (OSH). This statement is based on the self-conception of ergonomics and the level concept of human work.

Recent interest in evidence-based design (EBD) by the U.S. healthcare industry has led to new questions about how to best use this knowledge to improve the efficiency, safety, quality, and sustainability of new or existing facilities. Proponents of EBD claim that it enhances healthcare outcomes by utilizing empirical research to drive decision-making during all phases of healthcare facility pla...

The authors describe a surgical technique which allows, without increasing costs, to perform laparoscopic cholecystectomy with a single incision, without using specific materials and with better surgical ergonomics. The technique consists of a longitudinal umbilical incision, navel detachment, use of a permanent 10mm trocar and two clamps directly and bilaterally through the aponeurosis without...

The main objective of this research was to identify factors that affected worker productivity, occupational health and safety in selected industries in a developing country. Fifty production managers participated in the study. Fifty-four percent of the managers reported hot environmental conditions, 28% a noisy environment, and 26% a lack of resources and facilities. Managers received worker co...
