In this paper the development of an automatic body temperature measuring system which can be attached to the milking machine has been studied. Since the disease is highly related to the body temperature of the cattle, early detection of the abnormal temperature would prevent the severe problems which may occur in dairy farms. The electronic component AD590 is used as a temperature sensor for the system. The device is highly robust against the noise since the output signal is the current. So it can be applied to the long distance sensing. The resolution of the signal is $0.1{\circ}C$ and the current is 10 mV. Also the A/D converter is designed for interfacing the sensor with a computer. A temperature measuring experiment using the developed system has been done for measuring the temperature of human beings and the system was proven to be useful for measuring the body temperature of the dairy cattle properly.

The solid particle erosion behaviour of unidirectional carbon fiber reinforced plastic (CFRP) composites was investigated. The erosive wear of these composites was evaluated at different impact angles (30°,45°,60°,90°), different impact velocities (40, 55, 60,70㎧) and at three different fiber orientations (0°,45°,90°). The erodent used was silica sand with the size range 50-100㎛ of irregular shapes. The result showed ductile erosion behaviour with maximum erosion rate at 30° impingement angle. The Fiber orientations had a significant influence on erosion. The erosion rate displayed a strong dependence on impact velocity which followed the power law E∝V<SUP>n</SUP> for all materials. Based on three factors impact velocity(V), impact angle(α) and fiber orientation angle(β) a general method was proposed to predict the erosion rate of unidirectional fiber reinforced composites.
