ISO 9000 Quality Management Standards Series aims to improve the products and services regarding customer satisfaction. The main purpose is to increase quality. On the other hand, having a special importance to mining, OHSAS 18000 Occupational Health and Safety Assessment System Series aims to provide safer, more tranquil and more healthy working environment to the labors. Both of these management systems are continuously improved and increase their importance in the world. This study evaluates ISO 9000 and OHSAS 18000 series in a comparative and criticizing scope and complementariness of the standards to each other is examined. Existing conditions in our country are determined in mining perspective and some comments are given to improve existing condition. Literatural information is given about both of the series in the study and these information is supported by some case studies. Case studies covers not only, a leading company in Turkey namely MANGAN Marble &amp / Granite Inc. but also some other companies and establishments. Studies show that there are some problems observed in the implementation of both series. The main problem is commitment of the top management. Other problems are documentation and training of the personnel. These problems are more serious in small scale mining companies and quarries. Although existance of these problems is highly possible in the mining companies applying ISO 9000 and OHSAS 18000 series are very beneficial regarding the increase in the quality of products and therefore it&amp / #65533 / s advantages and in providing a healthy and safe working environment and become a necessity.

Mobile devices are becoming widely common today. As the number of mobile devices continue to grow all around the world, its functionality is extending and mobile technologies are gaining more popularity in every aspect of our life. Today, wide range of mobile services is offered to people. The purpose of our study is examining the customer value of mobile services for individuals or citizens. A value model for mobile services has been proposed with five dimensions: Functional Value, Social Value, Emotional Value, Epistemic Value and Economic Value. The effect on each value dimension on Intention to Use (ITU) is aimed to be determined. A survey instrument for mobile Internet services and short message services (SMS) has been developed to validate the proposed model. After assuring the reliability of instrument with a pilot study, data was collected from 303 people working in information and communication technologies (ICT) sector in Turkey. For analyzing proposed model variance-based structural equation modeling (partial least squares) was used. Before evaluating model, exploratory factor analysis (EFA) was conducted to indentify underlying constructs. Based on EFA results, Functional Value was found to have sub-dimensions namely: Ubiquity Value, Performance Value and Security Value. The measurement model was analyzed using confirmatory factor analysis (CFA). The structural model was analyzed using predictive power. For both mobile Internet and SMS, moderate predictive power has been gathered. Finally, the effect of each value dimension on intention to use (ITU) has been evaluated. Ubiquity Value, Performance Value and Epistemic Value have significant effect on ITU for mobile Internet. On the other hand, Economic Value and Performance Value have significant effect on ITU The indications of this research will be valuable for providing information about customer value of current mobile services.

The thesis investigates the elements of a consistent strategy for favorable acquisition and utilization of Flight Simulation Training Devices (FSTD), thus Full Flight Simulators (FFS) and Flight Training Devices (FTD). The primary purpose is to determine a knowledge-based strategy for the end-user, acquisition professional, aviation firms and institutions. Hence, it could be possible to shed a light for cooperative groups and main institutions of national innovation system involved in entrepreneurial and innovative efforts regarding complex technologies like FSTD. In the sample study, 114 pilots from varied sources were administered a questionnaire and their FFS and FTD perceptions were statistically tested regarding each &ldquo / technology&rsquo / s usefulness&rdquo / in four types of training. Another variable, each &ldquo / technology&rsquo / s ease of operation and use&rdquo / was also tested additionally via agent-based model whether it had any effect on technologies&rsquo / selection processes. It could be inferred that that aviation institutions and firms could acquire and utilize FTD as a complementary to both aircraft and FFS within a range of 30-60% depending upon type of the training. Moreover, FTD could be acquired and utilized as a substitute to FFS for Instrument Flight Training (IFT). The FTD&rsquo / s usefulness for IFT was rated as 67% by the military pilots. The research also asserts that the aviation institutions and firms as well as cooperative groups and organizations could favor the established strategy and policy during their FSTD related efforts at &ldquo / micro and meso-level&rdquo / . The final aim is to create a collaborative medium and a synergy for those agents.
