Article Citation - WoS: 1On-Site Measurements of Temperature and Humidity Conditions for the Comparison of Urban and Rural Sub-Spaces of Traditional Settlements: Historical City of Mugla, Turkey(Taylor & Francis, 2023) Timur, Barış Ali; Başaran, Tahsin; İpekoğlu, BaşakOne of the significant processes that ensures realistic determination of the energy needs of historical buildings is case-specific definition of their local microclimatic conditions. Accordingly, the aim of this study is to determine differences for the parameters of temperature and humidity in urban and rural sub-settlements of the historical city, Mugla/Turkey. Study method consists of on-site measurements of these variables in sub-settlements for comparisons. As a result, it was identified urban zone shows heat island characteristics with warmer, drier, and more stable conditions; while rural sub-settlement remains cooler, more humid, and more erratic. In parallel, calculated extents of these differences demonstrate the significance and necessity of on-site measurements and consequential microclimatic zoning of historical cities as conservation/planning tools for responding to the thermal needs of architectural heritage. A key application of these processes would be the establishment of local databases of case-specific weather data to be used in thermal simulation assessments.Article Citation - WoS: 2Citation - Scopus: 3Integration of Archaeological Heritage in Metropolitan City Centres With Urban Life: Agora of Smyrna(Taylor & Francis, 2022) Çalışkan, Merve; Hamamcıoğlu Turan, MineArchaeological sites located in metropolitan city centres in Turkey are subjected to diverse interventions. However, they are mostly isolated from the rest of the historical environment and become alienated from urban life. The aim is to identify an integration framework for archaeological sites in metropolitan city centres with contemporary urban life. A case study approach is employed, focusing on the Agora of Smyrna in İzmir, Turkey. Literature review on the case and similar cases, analysis of similar cases, literature review on integration criteria, survey, and a Delphi study to understand expert opinion were carried out. As a result, improving the quality of urban life and the good reputation of Agora’s vicinity, and the presentation, management, and usage of Agora itself support its integration. Nevertheless, the ‘presence of public concern for the conservation of the site’ is still the most important for the integration of the Agora with urban life.Article Characterization of Yellow Patina on Stone Surfaces by Instrumental Analysis Including Libs(Taylor & Francis, 2022) Badur, Fulya; Aras, Nadir; Yalçın, Şerife; Böke, HasanYellow patina formed on the stone surfaces of historical buildings, monuments, and archaeological structures due to weathering is considered a value of the building in the conservation of cultural heritage studies. Although yellow patina layers can be easily distinguished on white marble surfaces, it is not possible to distinguish them on the yellow travertine surfaces with the naked eye. It should be taken into account in yellow travertines as well as marble surfaces before conservation treatments of the stone. In this study, mineralogical and chemical compositions and the thicknesses of yellow patina layers formed on yellow travertine and marble surfaces in Aizanoi, Aphrodisias, and Hierapolis archaeological sites in Turkey were analyzed in order to constitute a conservation approach in the archaeological sites. In this respect, XRD, FT-IR, SEM-EDX, and LIBS were used in the determination of compositions and thicknesses of yellow patina. Although LIBS analysis is a more convenient method to investigate patina layers on stone surfaces, this technique is not as well known as the others. Yellow patina layers contained calcium oxalate in the form of whewellite (CaC2O4.H2O). Their thicknesses were between 15 and 100 μm and should be protective against weathering on travertine and marble surfaces. Highlights LIBS analysis seems to be the most convenient micro-destructive method to estimate the thickness of the yellow patina layers on the marble and yellow travertine surfaces. The determination of the thickness of the yellow patina is critical to keep irreversible cleaning interventions, especially for the yellow travertines due to their similar colors. Yellow patina is mainly composed of calcium oxalate with clay minerals and organic compounds.Article Citation - WoS: 1Citation - Scopus: 1Anastelosis of Greco-Roman Temple Remains in Western Anatolia: Principlis, Implementations and Assessment(Taylor & Francis, 2020) Toköz, Özge Deniz; İpekoğlu, BaşakAnastelosis, which is defined as the reassembly of a structure by bringing together its existing original fragments, is a technique of conservation and presentation in archaeological sites. The aim of this study is to contribute to the conservation and presentation of the structures and to determine the basic principles to be considered during the implementation by analysing and evaluating the anastelosis implementation at temple structures in Western Anatolia, Turkey. The authors examined on-site evidence, archival and literature review. Analysis criteria were determined as emphasis of the structure within site scale and in original state, structural and visual integrity of the monument, authenticity, reliability, distinguishability, visual and material compatibility, reversibility and re-treatability. As a result, it was pointed out that the principles of reversibility/re-treatability and distinguishability should be managed while providing reliability, compatibility/structural and visual integrity in line with the preservation of authenticity.Article A Model for Assessing the Reuse of an Ancient Place of Performance: the Bouleuterion of Teos(Taylor & Francis, 2017) Çalışkan, MerveAncient places of performance are often considered for reuse as a means of promoting archaeological sites. Therefore, local authorities and decision makers have a difficult task of balancing the conservation and management of the sites with the carrying capacity. In this paper, the bouleuterion, a ‘rediscovered’ structure, at the Teos archaeological site, in Turkey is evaluated and presented as a preliminary case study with the hopes that these issues will be taken into consideration by the managing body in the creation of a management plan for the site. The evaluation is made by assessing socio-economic and intangible heritage significance, policies guiding changes at the site, a qualitative survey at the site and by defining the structure’s carrying capacity. The site’s strengths, weaknesses, opportunities, and threats are used to create criteria and make proposals for its reuse. The study concludes that the bouleuterion cannot be reused as a venue in its present condition and makes recommendations for future use.
