In the United States, unions sometimes joined by worker advocacy groups (e.g., Public Citizen and the American Public Health Association) have played a critical role in strengthening worker safety and health protections. They have sought to improve standards that protect workers by participating in the rulemaking process, through written comments and involvement in hearings; lobbying decision-makers; petitioning the Department of Labor; and defending improved standards in court. Their efforts have culminated in more stringent exposure standards, access to information about the presence of potentially hazardous toxic chemicals, and improved access to personal protective equipment-further improving working conditions in the United States.

Understanding of core body temperature, heat stress and heat stroke developed progressively over the centuries. Soldiers involved in military operations have a higher risk to develop heat stroke, and to not survive following the onset. This paper follows the evolving understanding of heat stroke and development of counter measures. At certain times in history, incomplete understanding of the causes of heat stroke led to the development of devices that did not lower the risk. As understanding improved, development of improved methods and devices became possible. In the present day, several designs for garments that can lower core body temperature or brain temperature have been developed, and would reduce the risk of heat stroke. These cooling devices include a vest and collar system. Further refinements of these designs to make them more practical would allow wider deployment.

For signal transmission in traffic today, different optical, acoustic, or other physical or technical means are used for information. The different kinds of traffic (water navigation, road and rail, and, later air transport) made traffic regulation necessary early on. This regulation, from its very beginning in ancient times, began by means of optical signals; nowadays, this remains the most important method. From the very start, minimum requirements for the navigator's vision, color discrimination, dark adaptation, and even visual field were needed. For historical reasons, it was in seafaring medicine that these first developed. Besides the development of the different signals, methods for checking the requirements were soon developed. National and international requirements have been very different. Only within the last 50 years has international cooperation led to the acceptance of general standards for the different traffic modes. This article discusses the technical development of optical signals for the different kinds of traffic, from ancient times to the present, and explains the development of minimum requirements for the different visual functions.

The number of minor traumatic brain injury (mTBI), cerebral concussions, is increasing and cannot be eliminated by any kind of equipment. Prevention strategies, such as the introduction of "checking from behind" rules have become effective in decreasing the number of severe spinal injuries. A new "head checking" rule should reduce mTBI in the same way in the following years. Mouthguards should be mandatory as an effective device for the prevention of dental and orofacial injuries, as well as reducing the incidence and severity of mTBI. A new internet database system, the International Sports Injury System (ISIS) should improve epidemiological analysis of head, face, and spinal injuries worldwide. ISIS should provide an internationally compatible system for continuous monitoring of risk factors, protective effects of equipment, and protective effects of equipment and effects of changes in rules through the years.

Purpose: To explore the social, economic, and legal influences on siderail use in 20th century American hospitals and how use of siderails became embedded in nursing practice., Design: Social historical research., Methods: Numerous primary and secondary sources were collected and interpreted to illustrate the pattern of siderail use, the value attached to siderails, and attitudes about using siderails., Findings: The persistent use of siderails in American hospitals indicates a gradual consensus between law and medicine rather than an empirically driven nursing intervention. Use of siderails became embedded in nursing practice as nurses assumed increasing responsibility for their actions as institutional employees., Conclusions: New federal guidelines, based on reports of adverse consequences associated with siderails, are limiting siderail use in hospitals and nursing homes across the United States. Lowering siderails and using alternatives will depend on new norms among health care providers, hospital administrators, bed manufacturers, insurers, attorneys, regulators, and patients and their families.

This paper provides a history of automotive safety and a review of biomedical research on human tolerance and occupant protection. It discusses current understanding of body kinematics and impact biomechanics that result in neck injury. Perspective is given on the linkage between mechanical forces that are the cause and physiologic disruptions that are the consequence of spinal cord injury. The public health aspects of injury and disability are discussed as well as the need for injury prevention.

From the beginning of the 16th century the use of the padded cap to prevent injuries of the middle-face and skull in infants during their period of learning to walk is documented in art and medicine. Especially the painters of the Dutch and Flemish schools left beautiful paintings and drawings showing children with head-pads. Till the end of the 18th century the use of the head-pad was widely spread over Europe. In the 19th century the educational concepts of Rousseau and Kant probably induced a rejection and an abolition of this useful protective cap, which has been rediscovered during the past 20 years.
