“…26 Educational programs, introduction of blunt needles, and a change in the ergonomics of the scalpels were brought into practice to combat the considerable risk of sharp injuries in surgical practice with some success. 27,28 The routine use of diathermy for skin incisions and tissue dissection may be a step further in reducing the number of sharps injuries.…”

“…In addition to subjective and objective methods of product evaluation and tasks, usability methods are widely used to study user performance while using a product. Various metrics such as safety, reliability, ease of use (Woods and Buckle, 2005;Wu et al, 2008;Vanderwal et al, 2011), task efficiency, precision, stability, duration (Lee and Chen, 2008;Wu et al, 2009;Jung and Hallbeck, 2005;Chang et al, 2007), etc. researchers have used it in the past to assess the usability of different types of products.…”

“…Researchers have conducted various studies such as examining the optimal grip span concerning an individual's anthropometry for isometric power grip exertion(Eksioglu, 2004). Objective measurements such as pressure pain threshold measurements(Madeleine et al, 2003), joint and body posture and deviation, grip force/force/ torque,(Motamedzade et al, 2007;Jung, 2008;Wu et al, 2009) and the size and distribution of hand pressure(Aldien et al, 2005) are some of the frequently performed measurements in objective methods(Bisht and Khan, 2013). Various researches have been performed in the field of ease of opening packaging.…”

In today’s increasingly competitive market environment, new packaging must meet more requirements than before to meet customer expectations. The packaging must meet not only functional and aesthetic requirements but also ergonomic requirements to ensure satisfying user experience. An important issue in ergonomic design is the identification of factors that lead to user comfort and discomfort. The packaging is a product that undergoes manual manipulation and given the various forms of packaging and it's opening and closing systems, they require using different grip types and movements. Using packaging that is not well designed can cause intense physical exertion and frustration for users. The subject of this paper is a review of methodologies for assessing the ergonomics of packaging products. Methodologies for evaluating the ergonomic characteristics of packaging provide a proposal for structuring the investigation. Also, it gives a proposal for the proper prioritization of a packaging problem that should be identified as the most dangerous risks for physical injuries or for causing stressful situations to users. First, it is necessary to gain a clear insight into how the users handle the packaging in order to create knowledge and a clear idea of what is useful or harmful in the existing packaging design and to find the potential for its improvement. There are various methods for studying, analyzing and evaluating user experience while using a packaging. Combining such methods with knowledge of the anatomical structure of the body and how it reacts to the load enables the creation of efficient and ergonomically designed packaging. This paper will present methodologies and guidelines for assessing and improving the ergonomic qualities of packaging. The aim of this paper is to define the key factors and most relevant methodologies for conducting successful ergonomic research.

This paper proposes a formulation method on comprehensive evaluation of plural muscle load by applying the methodology of multi-objective optimization. Muscle loads are formulated as objective functions that should be minimized, and comprehensive evaluation of muscle loads is formulated as a multi-objective optimization problem.Design of handrail position for sit-to-stand movement was used as the case study of the proposed method. The height and distance of handrail are design variable, and surface electromyography of anterior deltoid, triceps brachii, rectus femoris, and tibialis anterior were measured when participants stood from a chair with handrails. The ratio of the maximum voluntary contraction (MVC) was used as the indicator of muscle loads. Result from the measurement, it is found that the muscle loads of triceps brachii and tibialis anterior have trade-off relationship on the assumption that %MVC indicates the muscle loads. The higher and the closer the position of handrail is, the higher the muscle load of triceps brachii is, conversely, the lower the muscle load of tibialis anterior is. The two muscle loads were approximated as quadratic functions, and formulated as a multi-objective optimization problem. The optimization problem was solved by the satisficing trade-off method, and the Pareto optimal solution for the participants was obtained at which the height is 234 mm and the distance is 585 mm. The comprehensive evaluation of the two muscle loads probably expresses the sense of the participants more precisely than the use of either of the two muscles.
