The authors offer a review of themes within occupational health and environmental public health surveillance over the past decade. In reviewing the history of public health surveillance, the authors highlight key acts of Congress in the 1970s that have made the development of “modern” occupational health and environmental health surveillance possible—but which also failed to develop into a cohesive and well-connected data management systems across federal agencies. Separate agencies were tasked with different data collection, management and intervention tasks in ways that fragmented the surveillance system to the point of ineffectiveness.

The authors argue that effective surveillance for occupational and environmental health demands development of a clear purpose for collecting data and having the data available to make meaningful analysis possible. They turn to the CDC’s childhood lead prevention program to demonstrate these points.

Smart autoalarm guardrail is designed for helpping people emergency contact and remind the other drivers when car accident happen in remote area. People will drive on some remote area, or late night. If car accident happens, might be no one know the accident is happen. This design is help the litigant automatically make a emergency call, and send the location through the GPS when the car is crash the guardrail. As well as, it can turn on/flash the light within the accident area to warn the other drivers.

This design could help people in an unknow emergency situation, for example, the driver pass out when the traffic accident happen, and this design can help people to save life. However, I think this concept design might be cost a lot if it is applied into real life, because it means there are lots of guardrail need to install this system, and the government also need to prepare another extra fee for repair the guardrail after every accident.

Smart Guardrail is autoalrm and could be send location to the nearset emergency centre by GPS when the car crash into the guardrail. As well as the warning light within the area will be swithched on to avoid the potential sencond accident. The system is design to install into the highway guardrail, and use the circuit to make the system work. Therefore, the materials might be include electrical wire and circuit, and also plastic caution lights.

Smart Guardrail is considered as a good concept design, because it can be solve the emergency problem for traffic accident in some situation. This design is applied a common materials and method to solve problem. It is a small change and might make a big influenced. But the design could be used or not is depend on the cost would be proportional to the value or not.

This concept design is create a market which is within more functions and technologies for guardrail. In the existing market, there are some good design highway guardrail, such as EZY-guard smart guardrail. Most of the existing product are applied outter shapes and physical structures rather than some electrical technology. Compare to the existing products, this concept design is more challenged by the cost.
