The Getty Conservation Institute (GCI), located in Los Angeles, California, is a program of the J. Paul Getty Trust. It is headquartered at the Getty Center but also has facilities at the Getty Villa, and commenced operation in 1985.〔J. Paul Getty Trust. (About the Conservation Institute. ) Retrieved May 2, 2011.〕 The GCI is a private international research institution dedicated to advancing conservation practice through the creation and delivery of knowledge. It "serves the conservation community through scientific research, education and training, model field projects, and the dissemination of the results of both its own work and the work of others in the field" and "adheres to the principles that guide the work of the Getty Trust: service, philanthropy, teaching, and access."〔 GCI has activities in both art conservation and architectural conservation.〔Adams, Eric. The Getty's conservation mission. ''Architecture'', December 1997, vol. 86, issue 12.〕 GCI conducts scientific research related to art conservation. It offers formal education and training programs, and it published a number of scholarly books. GCI has supported field projects around the world to preserve cultural heritage. == Scientific projects == GCI scientists study the deterioration of objects and buildings, and how to prevent or stop such deterioration.〔Getty Conservation Institute. (About GCI Science. ) Retrieved August 26, 2008.〕 One of many projects in this area involved the effect of outdoor and indoor air pollutants on museum collections.〔Getty Conservation Institute. (Pollutants in the museum environment (1985-1998). ) Retrieved August 26, 2008.〕 Another project analyzed the cause of deterioration of the sandstone in the original National Capitol Columns now at the United States National Arboretum.〔 In addition, GCI "conducts scientific research on materials' composition."〔 For example, a project on the conservation of photographs has as one of its objectives the creation of an "Atlas of Analytical Signatures of Photographic Processes" which will provide "a precise chemical fingerprint of all the 150 or so ways pictures have been developed."〔Getty Conservation Institute. (Research on the conservation of photographs. ) October 2006. Retrieved November 8, 2008.〕〔Kennedy, Randy. (Arsenic and old photos. ) ''New York Times'', April 1, 2007.〕 As a part of that project, Getty scientists once examined the world's first photograph from nature by Nicéphore Niépce.〔Lyden, Jacki, and Dusan Stulik. (Analyzing the world's first photograph. Precious image studied at Getty Institute in Los Angeles. ) National Public Radio, April 7, 2002. Retrieved August 26, 2008.〕 Using X-ray fluorescence spectroscopy, reflectance Fourier transform infrared spectroscopy, and other techniques during the 2002-2003 project, they found (for example) that bitumen of Judea was present in the image.〔Harry Ransom Center, The University of Texas at Austin. (The first photograph: conservation and preservation. ) Retrieved August 26, 2008.〕 Scientists at GCI viewed the CheMin instrument aboard the Curiosity rover, currently exploring the Gale crater on Mars, as a potentially valuable means to examine ancient works of art without damaging them. Until recently, only a few instruments were available to determine the composition without cutting out physical samples large enough to potentially damage the artifacts. The CheMin on ''Curiosity'' directs a beam of X-rays at particles as small as 400 µm〔(【引用サイトリンク】url=http://www.inxitu.com/new/pdf/NASA%20invention%20of%20the%20year%20award%20v2.pdf )〕 and reads the radiation scattered back to determine the composition of an object in minutes. Engineers created a smaller, portable version, named the ''X-Duetto''. Fitting into a few briefcase-sized boxes, it can examine objects on site, while preserving their physical integrity. It is now being used by Getty scientists to analyze a large collection of museum antiques and the Roman ruins of Herculaneum, Italy.〔(【引用サイトリンク】url=http://www.newscientist.com/blogs/onepercent/2012/08/martian-rover-tech.html?DCMP=OTC-rss&nsref=online-news )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Getty Conservation Institute」の詳細全文を読む スポンサード リンク
