「近代の文化遺産の保存理念と修復理念」英語版

51difficult to obtain oil paint used in the originalfinish, as oil paint has been gradually taken overby synthetic resin-based paint. For such reasons,more synthetic paint is inevitably employedfor restoration, while intending to basicallyreplicate the original finish. It needs to be notedthat these two paints differ greatly in handling,the finished surface, and characteristics. So as toprevent confusion, approaches for paint finishesneed to be established through discussionsbased on preservation principles, taking intoconsideration the performance of each of thedifferent types of paint.　With structures of reinforced concrete orsteel-frame, paint finish is directly connectedto their wellbeing and therefore the problemis much more critical as compared to paintused in interior or exterior finishes. Becausethese issues have been discussed and dealt withelsewhere, they will not be repeated.　Whatever the circumstances may be,appropriate preservation methods need to bedecided upon through deep understanding ofthe significance of the property, to be revealedthrough surveys as academic material as wellas studies and evaluation in the meaning ofpreservation, not as a mere example of moderntechnology.(3) Maintenance of Historic Environmentsand SpacesIn the field of modernization period heritageproperties with industrial properties in particular,as have been introduced earlier, it is not rare toset the period of restoration in a preservationplan at the time when the place was in operationor when it ceased operation. In other words, if afacility is to be left intact as it was when it wasfunctioning, concrete measures for preservationof the interior spaces would be necessary.　There are machinery, various equipments,and other items used in production. Soiling,scratches, and graffiti can be found on thefloor, walls, and ceilings, which are traces ofthe workers’ activities. Preservation of theseelements and marks will become a major issueduring restoration.　These heritage properties differ greatlyfrom replicated objects exhibited in museumsin that they are primary sources themselves.However, when it becomes necessary duringrestoration to treat the structure or interiorand exterior finishes, there may be cases whereit is not possible to completely preserve thepresent condition. Restoration may requiresome objects to be moved temporarily or tobe treated in a way so as to enable futuremaintenance. Such cases will need to take intoaccount the conditions of each property fordeciding on preservation principles and theactual methods to be taken.(4) Anti-Seismic MeasuresWith temples and shrines as well as folk houses,structural reinforcement has been introducedrelying on past experiences. However, afterthe Great Hanshin Awaji Earthquake in 1995(Heisei 7), full-scale seismic protection beganto be adopted, regardless of building type,whether it be traditional Japanese architectureor Western-style architecture9).　With modern architecture and modernheritage properties, those of brick or stonemasonry which Japan had comparatively lessexperience restoring or those of large-scale,structural analysis and structural reinforcementhad been executed according to set proceduressince before this disaster. It was after the 1995earthquake that buildings of all structural typesand scales began to go through a process of
