Relative yields measured during each year were interpolated to 4 m2 grid size using ordinary kriging. The resultant interpolated yield maps were averaged across years to create a map of the mean relative yield, which was then used for cluster analysis. The mean yield map of post-classification was processed by applying majority filtering with window sizes that were equivalent to the grid sizes of 12, 20, 28, 36, 44, 52 and 60 m. The scale effect of management zones was evaluated using relative variance reduction, test of significant differences of the means of yield zones, spatial fragmentation, and spatial agreement. The results showed that the post-classification majority filtering (PCMF) eliminated lots of isolated cells or patches caused by random variation while preserving yield means, high variance reduction, general yield patterns, and high spatial agreement. The zoned result can be used as yield goal map for preplant or in-season fertilizer recommendation in precision agriculture.展开更多

However, few frameworks exist that allow for a comparative examination of existing policy instruments, as opposed to specific initiatives, which assess governance performance aimed at addressing issues arising in the coastal zone. This paper describes the process and findings for evaluating the feasibility of a modified Coastal Sustainability Standard (CoSS) framework that seeks to measure the effectiveness of individual planning instruments within overlapping spatial boundaries in the landward and marine areas in the southeast region of Cuba. Through workshops conducted in Santiago de Cuba and Guamá municipalities with key representatives involved in coastal management and planning, the utility of the framework was assessed using the main instruments of territorial planning in Cuba, namely integrated river basin management, territorial planning in coastal municipalities and marine and coastal management. While, the findings suggest that the modified CoSS framework can be used to assess the effectiveness of these planning instruments in the region, and workshop participants also suggested improvements to better match its use to the characteristics of the study region.展开更多

[Methods]International animal epidemics regionalization management experience and specific equine disease-free zone establishment were analysed and discussed based on the State and OIE principles. [Results]The regionalization management of specific equine disease-free zone with county administrative regions level of international recognition was established first in China,combined with the region's geographical barrier and animal health. [Conclusion]The aim is to to provide experience and reference for other areas to establish specific disease-free zone.展开更多

We put forward a geomatics-based systems engineering architecture to identify the location and extent of oil spills, thereby improving the ecological integrity of the world's oceans and helping contingency planners to determine required assets, personnel and other resources. This real-time, event-based and cost effective emergency management decision support system can aid in the classification, detection, and monitoring of oil spills in the marine environment. The developed Synthetic-Aperture Radar (SAR) processing and calibration techniques efficiently monitor environmental changes in inaccessible ocean regions, characterize oil spill scenarios, and help to identify spill sources. The system is used to improve emergency management in the Gulf of Mexico, with application to oil spills arising from Hurricane Katrina.展开更多

On the other hand, its effects for traffic safety are still doubted by many people. To make the possibility analysis, an experiment is conducted by using driving simulator. Regarding ISA ap- proaches, there are three modes: mandatory, voluntary and advisory. Among them, the advisory type seems to be the easiest one to introduce. Therefore, we focus on the advisory mode in this study by considering ISA just at the beginning stage in Japan. The experiment consists of four steps: without ISA, ISA using pictures, ISA using voices and again without ISA. The outputs obtained from the driving simulator are analyzed combined with the consciousness of the participants. The experiment shows that the ISA can improve recognition of speed limitation especially for people who have random rambling or looking aside tendency. Furthermore, the ISA especially when using voices can contribute in changing the consciousness of people who are aggressive in driving. Their driving speeds can reduce so that positive effects on traffic safety can be concluded.展开更多
