Of all the Western diplomatic personalities who served in Peking during the nineteenth century, Anson Burlingame was perhaps the most celebrated figure. He acted as the first American resident minister in Peking from 1861 to 1867. He also acted as the first 'Chinese' envoy to the Western courts from 1867 to 1870, when his untimely death at St Petersburg cut short his colourful diplomatic career. Viewed against this unusual background, it is not surprising that his diplomacy in and out of China became something of acause célèbreamong his contemporaries. With the passing of the events and men associated with his name, however, a new and deatched appraisal of the man and his diplomacy is in order. It is outside the scope of the present paper to treat his spectacular diplomatic mission on behalf of China in the Western capitals, better known as the burlingame Mission. This paper focuses instead on his role in the inauguration of the Co-operative Policy. In doing this, the apper attempts to shed some light on the origins of one of the most significant Western policies toward China.

As natural disaster occurs, the local and the central government should investigate the damaged fields promptly, analyze quantitatively the degree of damage, and establish an appropriate disaster recovery plan in accordance with Framework Act on the Management of Disasters and Safety in Korea. The purpose of this study is to assess the applicability of UAV photogrammetry for the management of natural disaster. First, we suggest small easy-to-use UAV-based investigation procedure for natural disaster damaged area in the phase of disaster recovery in Korea. Before drone-based aerial surveying, the field survey can be performed with DGPS RTK for GCPs setting-up around disaster site. In this paper, we generate three dimensional terrain information and high-resolution ortho-imagery and then analyse quantitatively damage degree by natural disaster using commercial UAVs and drone mapping technique. Finally, we evaluate the mapping accuracy and work efficiency of drone mapping for disaster investigation application through comparing with traditional investigation work process which was dependent on labour-intensive field survey. The resolution ortho-image map of within less 5cm of GSD generated by aerial photographs acquired from UAVs at the altitude of 100m~250m enabled us to check damage information such as facilities destroy or the trace of soil erosion around the river flooded and reservoir collapsed area. In addition, three dimensional point cloud data of landslide-damaged areas enabled us to more accurately measure the width and the depth of outflows caused by landslides, soil runoff distance, and landslide damage area. The photogrammetry-based drone mapping technology for the disaster damage investigation is expected to be an alternative approach to support or replace the labour-intensive disaster site survey that needs to investigate the disaster site quickly and timely.
