The use of information technologies has increased faster than the ability of their users to recognize the technologies' key issues, according to many international commercial and government experts. Interoperability, availability and security all are growing in importance as information technologies become increasingly indispensable in more aspects of society.
Researchers at one federal agency are adding a new dimension to remote access computing via the Internet. A computer program created through research at the agency provides a web-based interface that simplifies command-driven queuing systems and applications environments. Without extensive expertise in complicated command language, users can now perform computing tasks on remote systems as if directly connected to them.
While the security industry concentrates on protecting systems from external threats, a danger to information access is brewing from within organizations. The expansion of and growing reliance on networks is jeopardizing military information technology by exposing numerous sectors and even entire commands to errors that are introduced internally by a single entity.
The U.S. Department of Defense is not fully exploiting information technology in military operations and departmental procedures. For an organization that relies on information superiority and technological capabilities to put U.S. national defense at an advantage, the department is lax in thwarting potentially devastating threats to its information systems.
Just as information system users are becoming accustomed to the concept of cyberwar, a new form of information conflict is emerging that rests on a completely different set of principles. Popularly known as netwar, it is based on a strategy of accessing a network, not to destroy it but to maintain and operate it as a tool to gather support and maintain communications.
The Naval Research Laboratory, the U.S. Navy's primary in-house facility for basic and applied research, is taking a leading role in the development of advanced applications of both solid-state semiconductor devices and vacuum electronics-two technologies widely thought to be heading in opposite directions.
Lightweight ultrasound technology that captures three-dimensional images may help determine the extent of internal bleeding of injured soldiers on the battlefield at least 40 times faster than current equipment. Although the capability to acquire these pictures has been achieved in the past, a system currently being developed by a medical center under contract with the U.S. Defense Department would put this medical service closer to the front lines by making the equipment easily portable.
Technology providers are responding to the growing demand for telemedicine services by combining individual strengths. Companies that specialize in integration are working hand in hand with medical personnel to determine preferences and needs and then are bringing this information back to hardware and software developers for implementation into products. Individually, these companies could only bring part of the solution to the medical community; together, they are helping to increase the use of telemedicine.
Internal Defense Department research and development coupled with commercial off-the-shelf technologies is speeding medical care to wounded soldiers on the battlefield. In ongoing programs, scientists are investigating remote health maintenance and trauma care tools ranging from dog tags that hold an entire medical history to diagnostic equipment that helps evaluate the severity of an injury.
The same wires that carry voice transmissions to individual telephones within an organization are now delivering data, television-quality video and stereo-quality sound directly to the desktop. This allows businesses and agencies to provide multipoint videoconferencing, video-broadcast and video-on-demand capabilities to employees without installing additional infrastructures or overloading existing information technology components or networks.
