Abstract

The use of a compact, mobile, relatively inexpensive electromechanical patient-contouring mechanism is described. The system utilizes a Numonics Model 224 graphics digitizer suspended over the patient. The digital X and Y coordinates of the patient contour in either of multiple, parallel transverse, or sagittal planes are inherently accurate to within +/-0.25 mm over a total reading are of 60X90 cm. Display features include the interface to an analog 11-in.X17-in. X-Y plotter with a variable scale-down factor for those contours which would otherwise be larger than the plotting surface. The system is easy to use and may also be readily interfaced for on-line entry of patient contours to calculator- or minicomputer-based treatment-planning systems.

Effects of chamber depth on the motion pattern of human spermatozoa in semen or in capacitating medium.

The computer-aided sperm analysis system (CASA) permits precise calculation of the trajectory characteristics of human spermatozoa. Comparison between different chamber depths (10, 20 and 100 microns) revealed variations in the results, which were more evident as the magnitude of the spermatozoon flagellar beat increased. In seminal spermatozoa, the reduced amplitude of movement, linked to the relatively short flagellum and high viscosity of seminal plasma, indicates that the 10 microns-deep chamber can be used for motion analysis without involving extensive modifications. On the other hand, analysis of quicker movement, such as in capacitated spermatozoa, revealed large variations; in particular the proportion of non-progressive hyperactivated spermatozoa was higher in the 20 microns than in the 10 microns chamber (17.9 +/- 14% and 6.9 +/- 4.5% respectively, P < 0.01). In fact the distribution of non-progressive and progressive hyperactivated spermatozoa is depth-dependent. It is therefore necessary to use a chamber of at least 20 microns in depth for sperm analysis in capacitated medium.

The future of nursing in a technological age: computers, robots, and TLC.

The computer has become a major tool in the medical treatment of disease. Computers can record vital signs, keep records, and provide central networks for interactive diagnosis. Individual medical histories can be contained in an optical card the size of a credit card. Advances in technology just over the horizon will permit an individual to consult a computer much as one now consults a physician for diagnosis, recommendations, instructions, and treatment. Surgery can be conducted in "virtual space," with the physician operating inside the body (via computer) as if he or she were present at the site of the surgery. Only a step beyond this is the development of robots who can do a better surgical job than a human being. What is missing from this scenario? Tender loving care. That is the nurse's job, and it is something that computers cannot do because it involves feelings and human communication that are beyond mere technology. Consequently, nurses will be needed long after physicians have passed into limbo. The practical lesson of this look into the future is that, although nurses certainly must remain in touch with the cutting edge of technology, their primary purpose will be to retain and sharpen the skills that Florence Nightingale introduced. Human response will never be replaced by technology, and the unchanging need for the nurses' caring function will assure their future.
