Noise, which is a noteworthy problem in the world of workers, influences the health, safety, productivity and efficiency of those working in heavy industries and especially those working in petroleum industry. The objective of this study is to reassess the protective measures, taken previously by the company, from the point of view of the negative effects of noise on the workers. For this purpose, two approaches are adopted. Firstly, through questionnaires (response rate: 86%) distributed to workers, their subjective rating of, the noise levels to which they are exposed, the factors affecting their working efficiency and, their working conditions are searched. Secondly, noise levels, in the buildings rated as highly and very highly noisy, are measured by sound level meter. Self-exposure of 28 workers is measured by dosimeter. The overall ambient noise level of the 11 buildings and effect of noise on the working efficiency of the workers working in these buildings were respectively found to be moderate and slightly affected. The workplace index was 3 (out of 5). The working conditions index was on the average 4 (out of 5). The Leq values measured in six of the buildings were found to be in the range of 66, 8 – 100, 0 dBA. 12 out of 28 workers were observed to be exposed to noise levels greater than 80 dBA. The objective (noise measurements) and subjective (questionnaire) results obtained at the end of the afore-mentioned approaches will be of help in the orientation of the workers while estimating their work efficiency and will also serve as a data base for the planning strategy of the interested company.

Impacts of participant related factors on rebar supply chain performance in SMEs Yavuz, Zeliha Banu; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2012) The improvement of construction systems and management systems do not move together in construction industry, not using the effective management approaches decrease the productivity of the work. The firms both in national and international area in manufacturing industry use supply chain management to preserve their competitive force. As material costs account for a high percentage of the overall cost, the success of a project is heavily dependent on material related factors and processes. In Turkey because ...
The Effects of restructuring in the property development sector on urban processes: a case study on Erzurum and Kayseri Dursun, Defne; Ersoy, Melih; Department of Urban Policy Planning and Local Governments (2015) Urban processes are affected by the relation between capital accumulation processes and the production of built environment. Capital-switching approach assumes that the capital flows into the built environment to overcome its overaccumulation problems. Besides, the investments made on built environment are accepted as the locomotive of the economic development through their backward and forward linkages. These economically reductionist mainstream approaches fail to explain the Turkish experience. This thesi...
Evaluating the use of satellite-based precipitation estimates for discharge estimation in ungauged basins Soytekin, Arzu; Akyürek, Sevda Zuhal; Department of Civil Engineering (2010) For the process of social and economic development, hydropower energy has an important role such as being renewable, clean, and having less impact on the environment. In decision of the hydropower potential of a study area, the preliminary condition is the availability of the gages in the area. However, in Turkey, the gages in working order are limited and getting decreased in recent years. Therefore, the satellite based precipitation estimates has been gaining importance to predict runoff for ungauged basi...
Utilization of soda and beer wastes in cementitious systems Aleessa Alam, Burhan; Yaman, İsmail Özgür; Department of Cement Engineering (2009) To maintain the sustainability of cement and concrete production, there is a trend to use wastes in their production. Soda waste, generated by soda ash production process, and beer waste, generated by beer filtration process, are two locally produced wastes in Turkey and many other countries. The nature of these wastes, mostly their fineness, makes them possible to be used in concrete production, especially as a viscosity modifying agent in the self consolidating type of concrete. In this study, the additio...
Development of the holistic work system framework (hwsf) with the aid of information systems research design science guideline Özalp, Egemen; Baykal, Buyurman; Department of Information Systems (2014) Today almost every market, either service or industry, is utilizing Engineering or Information Technologies (IT) in their Work Systems (WS) extensively. Enterprises operating in these markets continuously seek methods to increase the efficiency and effectiveness of this utilization to gain Business Value, and achieve Business Goals. Works on Business Process Management (BPM), Technology Adoption (TA), or Enterprise Architecture (EA) are major instances of such methods. There are several models or standards ...
