This paper describes a low-cost and flexible vegetation monitoring system and compares it with traditional remote sensing systems usch as airplanes and staellites. We have developed a small unmanned aerial vehicle(UAV) equipped with visible and infrared cameras for vegetation obsevation. This system can automatically generate widespread high-resolution mosaic image and calculate the vegetation index from the multiple aerial images collected by an autonomous flight of the UAV. We performed monitoring experiments at Yawata moor in Hiroshima Prefectrue. From the experimental results, we conclued that the small UAV system was effective and useful for carrying out low-cost and flexible vegetation monitoring.

Aerial cables in urban area are complicated. On the other hand, to check interferences between heavy machines and road features, a safety and efficient 3D road environment survey system’s necessity is increasing in the field of civil engineering. In this paper, efficient and robust aerial cable measurement method using a Mobile Mapping System (MMS) and its automatic extraction method from 3D point cloud model are introduced. And the MMS enablesto measure the road 3D environment and reconstruct 3D environment efficiently. The MMS can acquire road environment data at the cruising speed. The MMS enables to detect aerial cables in excess of 6mm, and its detection ratio is 99.6%. The extracted aerial cable is registered to GIS and the result of registration to a GIS is introduced.

The present study aimed to clarify the effects of Agaricus brasiliensis KA21 (i.e., Agaricus blazei) mushroom on circulatory function. Spontaneously hypertensive rats (SHRs) were fed 10% A. blazei-containing pellets (agaricus group) or normal pellets (control group) for 5 weeks from 6 to 11 weeks of age. For Experiment 1, tail blood pressure and heart rate were measured in the conscious SHRs. For Experiment 2, echocardiographic and blood biochemical measurements were performed in the anesthetized SHRs. In Experiment 1, blood pressure and heart rate were significantly lower in the agaricus group compared with the control group throughout the observation period. In Experiment 2, the agaricus group also showed a significant decrease in cardiac output accompanied by a decrease in heart rate and an increase in early and late ventricular filling velocity (E/A ratio). Moreover, levels of escape enzymes such as creatine kinase (CK), CK-BB, CK-MB, asparate aminotransferase, lactate dehydrogenase, and aldolase were significantly lower than in the control group. We concluded that the ingestion of feed containing A. brasiliensis KA21 can improve hypertensive cardiovascular hemodynamics by decreasing the working load of the heart, presumably by lowering the sympathetic nervous tone in SHRs.
