The ambulance service is an important component in the emergency medical system of a community. The availability of performance information on several aspects of the ambulance system may improve ambulance management. The location of new ambulance stations, selection of the destination hospital for urgent cases, scheduling of crew changes, and evaluation of crew performance can be approached through an examination of existing data. Management use of such an information system by the Victorian Civil Ambulance Service in Melbourne, Australia is included in the discussion.

An automated procedure for the determination of beta-plus-pre-beta-lipoprotein cholesterol is described and evaluated for mass screening of hyperlipoproteinemias. It is shown that this method fulfills the requirements for an ideal method for primary screening: it can be used in non-fasting samples, is capable of detecting hyperlipoproteinemias characterized by both cholesterol and/or triglyceride abnormalities, is fast, accurate and extremely inexpensive. Evidence is shown that the method is extremely useful for primary screening and, when tested in a coronary screening detection program, gave only 4% false positive and 3.4% false negative results.

A computer operated system is described for determining the location of a subject fitted with a small sensing coil and telemetry transmitter. The system uses the geometric factors inherent in the value of the mutual inductance of a fixed and moveable coil. Results of a two-dimensional system are shown.

1) Serial thermograms were taken after the application of various intensities and durations of localized pressure on the medial surface of the human forearm. 2) Thermal response of the body surface to localized pressure was quantified. 3) It was found that usually a time period of between 1 to 3 minutes elapsed before the body surface attained a maximum elevation of temperature from the time the localized pressure is removed. 4) It was found that increased intensity of pressure (5 psi vs. 3 psi) and longer duration (20 minutes vs. 10 minutes) caused larger thermal responses. 5) It is suggested that high resolution medical thermography may eventually become a useful tool in the fitting of prosthetic and orthotic devices and for the prediction of pressure sores formation so prophylactic measures can be started immediately on immobilized patients.
1)在人体前臂内侧表面施加不同强度和持续时间的局部压力后，拍摄一系列热像图。2)量化体表对局部压力的热响应。3)研究发现，从局部压力解除后，体表温度达到最高升高通常需要1 ~ 3分钟的时间。4)发现压力强度的增加(5psi vs. 3psi)和持续时间的延长(20分钟vs. 10分钟)会导致更大的热响应。5)高分辨率医学热像仪可能最终成为一种有用的工具，用于假肢和矫形器的装配和预测压疮的形成，从而可以立即对固定患者采取预防措施。

The question of how pulsed microwaves induce auditory effects in animals and man leads to an examination of the parameters which determine the frequencies of maximum reception by the skull, and the positions of maximum energy deposition within the brain. The interaction of microwaves with a nerve membrane model and with live nerve cells is also discussed, as well as planned experiments to determine the microwave properties of membranes.
