In recent years, agricultural work is being automated and IT has been advanced in the field of agricultural machinery. The automatic steering apparatuses using GNSS and robot tractors are being developed. However, accurate GNSS is expensive and is difficult to acquire field conditions numerically. In this research, we developed a guidance system that acquires information on ridge line to extracts the target route of the vehicle using an inexpensive three-dimensional laser scanner compared to GNSS as a fundamental research of autonomous vehicle. In field experiments, a three-dimensional laser scanner with a depression angle was installed in front of the tractor, and the tractor was driven so as not to collapse the ridge installed in the field, and distance measurement data was acquired. By using the acquired distance measurement data, vertexes of the ridge were detected by self-made program, and approximate lines were obtained from these points to be the target trajectory. As a result, it was possible to obtain the target trajectory with sufficient accuracy to control the autonomous tractor.

A fixed-dose combination tablet of benazepril and pimobendan (Fortekor Plus; Elanco Animal Health) was tested in dogs with congestive heart failure (CHF) caused by myxomatous mitral valve disease (MMVD) in a three-arm, masked, randomized, non-inferiority clinical trial in Japan. The test group (n = 34) received Fortekor Plus twice daily. Two control groups received registered formulations of benazepril (Fortekor; Elanco Animal Health) and pimobendan (Vetmedin; Boehringer Ingelheim Vetmedica) with administration of Vetmedin twice daily and Fortekor twice (Control I, n = 14) or once (Control II, n = 19) daily. Diuretics were used in 22 dogs (32.8%). Global clinical scores decreased significantly from baseline in all groups; there were no significant differences between groups, and non-inferiority of Fortekor Plus compared to Control I, Control II, and combined Control I + II groups was demonstrated. There were no significant differences between groups for relevant clinical chemistry and hematology variables or frequency of all adverse events. Frequency of emesis was significantly (p = 0.0042) lower in the Fortekor Plus (8.8%) group than in the Control I + II (39.4%) group. In conclusion, Fortekor Plus had non-inferior efficacy and was associated with significantly less emesis compared to Fortekor and Vetmedin in dogs with CHF caused by MMVD
