Computer graphics or “virtual reality” techniques can aid task visualization for planning, action previews and predictions, operator training, and visual perception of non-visible events in telerobotic operations. The utility of computer graphics in remote control can be significantly enhanced by high-fidelity calibration of virtual reality images to actual TV camera images. A calibration techn...

For more than 150 years, doctors have had the ability to transmit medical information to advise and assist their colleagues in remote locations via teleconsultation using a variety of communication modalities. In surgery this has evolved into the telementoring of minimally invasive procedures, particularly, robotic surgery, which have become relatively commonplace in urology. The ultimate progr...

During 1973, interviews were conducted with more than 11,000 adult assistance recipients in the Survey of the Low-Income Aged and Disabled. The sample members were reinterviewed during the last 3 months of 1974, approximately 1 year after the implementation of SSI. This article analyzes the impact of SSI on the economic status of the 1973 adult assistance populations. The analysis considers the...

Since the end of the war the number of persons receiving aid under the State-Federal programs of public assistance has increased almost steadily and the cost of the programs has climbed. The increases, though partly the result of higher living costs, also reflect the greater public awareness of need and the consequent action by State legislatures to provide more adequately for needy persons. Ac...

This is the first study to evaluate the prevalence of headache and migraine among Tupiniquim Brazilian natives. A high prevalence of headache was found and the most prevalent headache was migraine. Women were more commonly affected than men. A high impact of headache was found, especially among migraineurs. Half of the headache sufferers were under medical assistance for headache given by the g...

The term "natural childbirth" encompasses a variety of methods, including the Lamaze, Bradley, and home-birth approaches, which place more or less reliance on medical technology. Aristotle's analysis of three levels of human activity--digestion and reproduction, perception and locomotion, and abstract thinking--and Pellegrino and Thomasma's classification of the "living body," "lived body," and...

The organization and implementation of anti-epidemic support in the Polish Armed Forces carrying out mandatory tasks in theatres of military operations poses a difficult and imperceptible problem in the field of medical assistance of military contingents. One of the operative instruments designed for limitation of the spread of infectious diseases and its health consequences among participants ...

Telepresence or virtual presence has became more and more commonplace thanks to evolutionof technology which implies an opening to the telework capacities. Telework is essentially linkedto virtuality and telepresence and consequently linked to robotics and computing as well ascommunications. This work deals with the methods and the tools necessary to the achievementof a tele...

High fidelity computer graphics preview and predictive displays provide substantial aid in four major space telerobotic activities: overall workspace design including viewing conditions, specific workspace analysis for given tasks in a fixed setting, operator training, and reduction of operator’s uncertainty and operation time under communication time delay conditions. Computer graphics display...
