The main focuses of the study are (i) to define the as-is acoustical features of the Surp Yerrortutyun Church and its current acoustical problems by means of field measurements and acoustical simulation analyses, and (ii) to assess acoustic performances of some scenario-based proposals for the specific musical- and speech-related activities which are the real demands of local authorities. The investigation is composed of acoustic field measurements held in the monument and the acoustic simulation analyses of the monument’s computer model, which is calibrated according to the data achieved by field measurements. The acoustic parameters of Reverberation Time (T20, s), Early Decay Time (EDT, s), Clarity (C80, dB), and Speech Transmission Index (STI, unitless) were used for the evaluations of field and simulation data. The field measurements exhibit the existing acoustic environment of the Surp Yerrortutyun Church, which underwent many repairs. All proposals integrate sound absorptive surfaces, made of transparent fabrics (curtains), into the Church space, attached or hung free by mountable-demountable (temporary) encircling systems. The results show that the Surp Yerrortutyun Church in existing conditions suffer from excessive longer reverberation times and low clarity levels. The blurred sound environment and poor speech intelligibility in the Church point out the need for acoustic improvement. When compared to the recommended values in the literature, all acoustical rehabilitation proposals enhance the Church’s acoustic environment at medium and high frequencies, specifically for music-related activities. The outcomes of the research conducted on this church museum are expected to be guiding for the identification and rehabilitation of acoustic problems of similar monuments as well as for the development of innovative and portable acoustic control assemblies, which can be temporarily used in monuments.

Modelling Energy Consumption of the Republic of Serbia using Linear Regression and Artificial Neural Network Technique
Protic, Milan; Fathurrahman, Fahman; Raos, Miomir (Mechanical Engineering Faculty in Slavonski Brod, 2019-02-01)
The objectives of the study are twofold. First, we aim to examine the most influential socio-economic indicators to explain energy consumption in Republic of Serbia. The second objective is to develop models that are able to predict the future energy consumption in the Republic of Serbia. This could be the first important step towards proper energy management in the country. Several potential socio-economic indicators are selected to be the independent variables. Regression analysis is conducted to select t...
Elementary students’ metacognition and epistemological beliefs considering science achievement, gender and socioeconomic status
Topçu, Mustafa Sami; Yılmaz Tüzün, Özgül (2009-11-01)
There were two focuses in this study. The first one was to investigate the relationship among science achievement, metacognition, and epistemological beliefs for both 4th and 5th grade and 6th through 8th grade students. The second focus was to explore the relationships among gender, socioeconomic status (SES), metacognition, and epistemological beliefs. Altogether 941 elementary students participated in this study. For 4th and 5th grade students, knowledge of cognition, regulation of cognition, and qui...
Relationships of safety climate and organizational citizenship behaviors in aerospace industry in Turkey
Kılıçaslan, Mahmure Dilayla; Demirel, Nuray; Ocaktan, Murat Can; Department of Occupational Health and Safety (2019)
The aim of the current study is represented in three main aspects. Firstly, it is aimed to check the fit of "the risk perception model" developed by Deery (1999) among young male non-professional and taxi driver samples. Secondly, it is aimed to analyze the effect of driving as a profession on risk perception and risk-taking behaviors of drivers. Thirdly, it is aimed to facilitate driving simulation in order to measure driver behaviors by comparing the results with self-reported driver behaviors. 40 young m...
