Article Citation - Scopus: 1Characteristics and Production Technologies of Byzantine Building Bricks From the Anaia Church in Western Anatolia(Springer, 2023) Çam, Elif; Uğurlu Sağın, ElifFired bricks were valued as essential building materials in the central tradition of Byzantine architecture in Constantinople (Istanbul), Anatolia, and the Balkans. In this study, Byzantine bricks from three construction periods, covering nearly nine centuries (fifth-fourteenth centuries), of Anaia Church (Kadikalesi) in Western Anatolia were investigated to determine their characteristics, raw material properties, and production technologies. The characteristics of the bricks were evaluated and compared in order to identify similarities and differences between the periods and to investigate the continuity of the tradition of brick production over centuries. Basic physical and colorimetric properties, chemical and mineralogical compositions, thermal behavior, and microstructural and mechanical properties of bricks were determined by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (SEM-EDS), Fourier-transform infrared spectrometry (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and mechanical tests. The results indicated that all the bricks in the Anaia Church were brown-beige colored, highly porous, low-density materials with low mechanical strength. They were produced from Ca-rich clays, probably obtained from two different sources used during all construction periods. The mineralogical composition and thermal properties revealed that the bricks from the first and second periods were fired at between 800 and 900 & DEG;C and the bricks from the third period were fired at < 850 & DEG;C. Greater calcium content and firing temperatures were found to reduce the total porosity and the number of small pores (< 10 & mu;m) and increase the mechanical strength of the bricks. The results of the study revealed no significant differences in the production of bricks, including raw material sources and kiln conditions, for the different construction periods of the church.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 Citation - WoS: 3Citation - Scopus: 5Assessing Community Awareness for Participatory Conservation of Cultural Heritage: the Case of Tepebağ Tumulus and Its Surroundings in Adana Turkey(Emerald Group Publishing, 2022) Umar, Nur; Yüceer, Hülya; Aydın, RozelinPurpose: The purpose of this paper is to identify the levels of awareness of locals about conservation and cultural heritage, in order to develop suggestions and methods for them to participate in these processes. Design/methodology/approach: The method of research is based on face-to-face surveys, mainly questionnaires that were conducted with 1,200 local people. The data obtained was evaluated using the SPSS 25.0.0 V program. Findings: The results show that locals mainly find appropriate the assets that reflect their culture but disregard archaeological remains. The participation of locals in the conservation process will end up benefiting them economically. Social implications: It is currently accepted that effective conservation cannot be achieved unless its technical considerations are considered together with social and cultural aspects. Ensuring the participation of local people in the conservation process has proved to be important in the development of holistic and sustainable outcomes. In places, where multilayered cultural heritage exists and local residents are from different cultural backgrounds, a detailed assessment of cultural heritage perception that involves local people gains significance. Originality/value: It is project-based in the sense of adding the dimension of community awareness to the practice of cultural heritage conservation in the multilayered and multicultural places.Article Citation - WoS: 5Citation - Scopus: 6Revisiting the Conditions of Authenticity for Built Heritage in Areas of Conflict(Mdpi, 2021) Saifi, Yara; Yüceer, Hulya; Hurol, YoncaThis article examines the application of conditions of authenticity within the context of built heritage management in areas of political conflict, where heritage management can be seen as a political act rather than a means of protection. It focuses on values attributed to built heritage that can be targeted or reinvented by the dominant power in areas of conflict with minorities being powerless to intervene. The argument is built around the Agios Synesios Church in North Cyprus, which continued to be used by the Greek Cypriot minority following the island division in 1974. Although their way of life has been compromised, they have embraced forced change through using the church to maintain their ritual and religious practices; by doing so, they negotiate their values towards their heritage. In this case, the study shows that the conditions of authenticity are difficult to meet, given the means through which heritage management can be manipulated. Accordingly, the article aims to contribute to general discussions on the vagueness and enigmatic conditions of authenticity in areas of conflict. Different buildings in areas of conflict around the world suffer because of the political nature of heritage management, which makes the criteria of authenticity unviable.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 Citation - WoS: 5Citation - Scopus: 4A Quantitative Approach for Evaluating Intervention-Value Relations: Historic Mosques of Manisa, Turkey(Emerald Group Publishing, 2021) Büyükkılıç Koşun, Suna; Hamamcıoğlu Turan, MinePurpose This study aims to propose a systematic way of evaluating the impact of historic and current interventions on cultural asset values of monuments that have preserved their authentic functions so that future interventions can be better guided. Design/methodology/approach The study focuses on the Mosque typology. The case studies are chosen from a region that has a rich historic background, but has generally undergone rapid urbanization and faces extensive restorations today. Conventional site survey, archive and historical research and visual analysis are made, but the evaluation process has been designed. As a result, scale and intensity of interventions and disasters and the vulnerability of the monument should be identified for each period of the asset. Variations in the intensity of esthetic or historic qualities and the environmental settings should be credited, rather than the utilitarian necessities. Findings Mosques and their environs are most vulnerable in terms of their architectural authenticity and site aesthetics. Originality/value The objects studied in the previous studies present a variation, but the majority of the work is carried out with conventional evaluation methods with the emphasis on building scale. However, the mosques are affected by the interventions and disasters, not only as single architectural entities but also as the focal elements of their neighborhoods. So, the intervention-value relations should be understood both for building and site scales. An evaluation process is proposed for understanding the change of values with respect to interventions and disasters throughout history by combining qualitative and quantitative techniques.Article Construction Techniques of Hayat Houses: Two Case Studies in the Vicinity of Izmir(American Society of Civil Engineers (ASCE), 2019) Turan, Mine; Aktaş, Engin; Mamaklı, Fatma Sezgi; Kaplan, ZişanThis study aims to contribute to the analytic studies on constructional aspects of the hayat house typology with an eye on its historical evolution for conservation purposes. The method used included a review of the surviving examples of the typology in Izmir and its vicinity and the selection of two intact examples whose structural components are legible: one from the earliest period and the other from the latest period. The examples selected are Kerimaga Konagi in Birgi, odemis, Izmir and a house in Kirkagac, Soma, Manisa. The early example (probably eighteenth century, constructed over the remains of an older house) sustains the traditional box system in its wooden upper story that integrates with the roof. The provision of level differences on the upper floor, the traditional relationship of the sitting level-window design, and masonry base are its authentic features. The late example (probably early twentieth century) presents signs of modernization, such as the establishment of a systematic wooden roof and wall frames in relation to each other, lack of diagonals in the perpendicular wall frame, avoidance of projections, and relatively elongated windows placed at higher positions.Article Citation - WoS: 6Citation - Scopus: 4Conservation-Aimed Evaluation of a Historical Aqueduct in Izmir(American Society of Civil Engineers (ASCE), 2019) Mamaklı, Fatma Sezgi; Turan, Mine; Aktaş, Engin; Vardaroğlu, MustafaThe seventeenth century was the era in which Izmir became an international commercial center in the eastern Mediterranean. The vizier of the era, Koprulu Fazil Ahmet Pasa, noticed the scarcity of potable water in relation with the increasing population at the center of this harbor city and ordered the construction of an aqueduct on Melez Valley. The Veziraga Aqueduct was constructed in 1674. This article aims to identify historical, architectural, and structural characteristics of the Veziraga Aqueduct so that its heritage values and conservations problems can be understood. The geographical and historical characteristics of the Veziraga Aqueduct are described by taking the effects of site and the sociocultural situation of city into consideration. The architectural characteristics of the aqueduct are prepared by using the site survey data to reveal the current condition and find out the original state. Seismic behavior of the aqueduct is investigated by using two approaches: analytical equivalent static analysis and finite-element analysis. The historical, architectural, and structural characteristics of the Veziraga Aqueduct prove its historical, documentary, and aesthetic values.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.Article Citation - WoS: 29Citation - Scopus: 35Sustainable Bio-Nano Composite Coatings for the Protection of Marble Surfaces(Elsevier Masson SAS, 2015) Ocak, Y.; Sofuoglu, A.; Tihminlioglu, F.; Böke, H.Water repellency on natural stone surfaces is the most important issue in the protection of stone monuments from effects of atmospheric pollutants. In this study, effectiveness of a bio-nano composite coating, composed of a biodegradable polymer (poly-L-lactide [PLA]) and montmorillonite clay (MMT) was investigated for the protection of marble surfaces from pollution. The clay dispersion in polymer matrices was analyzed by using Scanning Tunnel Electron Microscopy (STEM) and X-Ray Diffraction (XRD), while protection performance was investigated by the measurement of surface roughness, wettability, water vapor permeability, capillary water absorption, and color changes on the marble surfaces. As a result, no alteration on the color of coated marbles was observed, significant improvement was obtained for hydrophobicity of the surface and inhibition of sulfation reaction on the exposed marble surfaces under acidic atmosphere. It could be said that PLA based nanocomposites seem to be promising materials as protective coating agents in reducing the effects of water and atmospheric pollutants on marble surfaces. © 2014 Elsevier Masson SAS.
