We update the epidemiology of lawnmower injuries, together with leading mechanisms of lawnmower injury in the United States, for the entire age range by using nationally representative data.
Data were obtained from the National Hospital Discharge Survey 1996-2003 and the National Electronic Injury Surveillance System 1996-2004.
Individuals in the 60- to 69-year age group had the highest push mower injury incidence in 2004, whereas those in the 70 years and older age group had the highest riding mower injury incidence. Children younger than 15 years also had a substantial injury incidence. Individuals in the 15- to 19-year age group had the highest rate of hospitalizations caused by lawnmower injuries from 1996 through 2003, with 0.72 per 100,000 person-years (95% confidence interval 0.07 to 1.36). Debris from under the mower hitting a body part or entering the eye was the most common mechanism for lawnmower injury. The second most common mechanism of injury was nonspecific pain onset after the ordinary operation of the mower. Fracture of 1 or more phalanges of the foot was the most common diagnosis among lawnmower injury hospitalizations, with 34.4%, followed by traumatic amputation of the toe, with 32.4%. There is an increasing trend of lawnmower injuries in the United States during the last 9 years.
Lawnmower injuries increase with age, with peaks in persons older than 59 years. Given the high incidence of projectile-related injuries, improved protective apparel and eyewear could lower the rate of injury for all age groups. The increasing trend of lawnmower injuries in the United States suggests that more must be done to prevent lawnmower injuries.
[Show abstract][Hide abstract] ABSTRACT: Concern over the negative environmental impacts associated with the production, use, and end-of-life (EoL) of cellular telephones is particularly high due to large production volumes and characteristically short time scales of technological and stylistic obsolescence. Landfilled or incinerated cellular telephones create the potential for release of heavy metals or halocarbons. While recycling of components other than batteries is still not a widespread activity, cellular telephone remanufacturing is becoming a reality. In fact, third party re-manufacturers of cellular telephones are already making significant profits from sales in emerging markets. The acquisition of OEM cosmetic parts, such as housings, is among the highest costs of the remanufacturing process, especially when considering the large number of different cell phone variants that re-manufacturers must be able to accommodate. To address this issue, the research described in this paper involves the design and prototyping of a Modular Housing Platform (MHP) for cellular telephones. The MHP has the capability to accommodate components from different cellphone models as a means of achieving cost savings and increased efficiency in the remanufacturing process.

[Show abstract][Hide abstract] ABSTRACT: Gardeners can be seriously injured when using power tools designed to cut and trim. This poses a public health problem that requires understanding of the risk of using these tools in order to develop sound preventive measures. Epidemiological data provide global descriptions of mechanisms for injury, whereas observational studies provide detailed descriptions of risk in user-product interaction. Both types of information are needed for successful risk communication programs and design improvement of consumer products. This paper describes observational research that investigates how product users perceive possible risks that arise from the usage of their electrically gardening tools. The study aims at achieving a contextualised understanding of risk perception that takes into account the concerns that influence users’ risk perception and subsequent activities. The paper describes the emerging insights on the users’ point of view on risk in using powered gardening tools. It discusses how risk perception research may support risk communication and the design of safe(r) products.
