Privacy Worry May Keep HIV Patients from Therapy
Patients infected with HIV are often concerned about the confidentiality of their HIV-positive status. In fact, some patients are so worried that they will actually give up treatment to prevent the release of this information, according to a report published in the August issue of AIDS Care.
Dr. Kathryn Whetten-Goldstein and colleagues from Duke University, Durham, North Carolina, studied the confidentiality issues of 15 HIV-infected patients from rural North Carolina locations. They were divided into groups designed to explore their attitudes toward, and experiences with, breaches in confidentiality.
"The fear of a breach in confidentiality is definitely affecting the care that HIV-infected patients receive," Whetten-Goldstein said. "Most studied patients had experienced or knew someone who had experienced a breach in confidentiality."
"Two types of breaches occurred," Whetten-Goldstein noted. "The first was a more obvious type of breach. One example was a nurse who told her child that her patient was HIV-positive out of concern that her child would play with the patient's child."
"The other type of breach was more subtle, one that providers might not consider breaches," Whetten-Goldstein explained. "This type of breach involves providers talking about a patient's HIV status without the patient's knowledge of the interaction."
"The law allows the sharing of information between providers within the same institution, but patient's consent must be obtained before providers at different institutions can share information," she pointed out.
"Patients in the study wanted providers to tell them when they are going to share information with other providers and why it is being done," Whetten-Goldstein said. "They also felt that providers should be punished when a breach occurs."
"However, because patients are often reluctant to seek legal action which may further expose their status, they felt that the system should regulate itself," she added.
All patients in the study refuse to receive any treatment because of the possibility to expose their HIV status.
A．Right
B．Wrong
C．Not mentioned

Automation
The term automation was coined around 1946 by the automobile industry to describe the increased use of automatic devices and controls in mechanized production lines. Today, it is widely used in a manufacturing context but is also applied outside of manufacturing in connection with a variety of systems in which there is a significant substitution of mechanical, electrical, or computerized action for human effort and intelligence. An operation is commonly described as automated if it is Substantially more automatic than its predecessor.
In its most general usage, automation can be defined as a technology concerned with carrying out a process by means of programmed commands combined with the automatic feedback of data relating to the execution of those commands. The resulting system is capable of operating without human intervention. The development of this technology has become increasingly dependent on the use of computers and computer-related technologies. As a consequence, automated systems have become sophisticated and complex. Advanced systems of this sort now represent a level of capability and performance that surpass in many ways the abilities of humans to accomplish the same activities.
Automation technology has matured to a point where a number of other technologies have developed from it and have achieved a recognition and status of their own. Robotics is one such technology. It is a specialized branch of automation in which the automated machine possesses certain characteristics. The most typical humanlike characteristic of a modern industrial robot is its powered mechanical arm. The robot's arm can be programmed to do a sequence of motions to perform. useful tasks, such as loading and unloading parts at a production machine or making a sequence of spot-welds on the body of an automobile. The robot will repeat the motion pattern until it is reprogrammed to perform. some alternative task. As these examples of robot applications suggest, an industrial robot is typically used to replace a human worker in a factory operation.
The field of robotics has its roots in the development of automation technology. Numerical control (NC) and telecherics are two important areas of technology that constitute the foundations of robotics technology.
Over the years, the social merits of automation have been argued by labour leaders, government officials, business executives, and college professors. No doubt the biggest controversy has focused on the employment issue: What is the effect of automation on employment？ There are other important aspects of the automation issue as well, including its effect on productivity, economic competition, education, and quality of life.
The advantages commonly attributed to automation include increased production rates, more efficient use of materials, better product quality, improved safety, shorter workweeks for labour, and reduction of factory lead times.
Automated machines are usually designed to operate at higher production rates than humans are capable of achieving. This increased productivity has been one of the biggest reasons for justifying the adoption of automated systems. Notwithstanding the claims of high quality from good workmanship by humans, automated systems are generally capable of carrying out the manufacturing process with less variability that humans make, thus yielding greater control and consistency of product quality. In addition, the increased process control makes possible more efficient use of materials, resulting in less waste.
Automated manufacturing systems often, remove workers from the workplace, thus safeguarding them against hazards in the work environment. In the United States, the Occupational Safety and Health Act of 1970 (OSHA) was enacted with the objective of making work safer and protecting the physical well-being of the worker on a
