The aim of this study is to evaluate the adequacy of the business administration education in terms of like, syllabus efficiency and social usefulness, with the help of the assessments of the major industrial companies in Turkey, and determine if there is a relationship between the education and situations of business administration school graduates in business life, and to construe this relationship if there is one.
Because there have been limited academic researches done in Turkey about the evaluation of the educational system and the job conditions for the graduates, the chance of using this research as a reference by enterprises and schools of business administration will add an extra value to this research.

Within this research, web poll method was used and the poll was sent to the “Turkey’s Major 1000 Enterprises” which are designated annually by İstanbul Chamber Of Industry. As a result of acquired dataset, it is possible to say that the business administration education is insufficient in some ways; especially in point of preparation the administrators for business life.

In this study, the decision support system (DSS) is development to monitor and analysis of the production for Medium and Small Enterprises that not to use any computer aided software for monitoring work process, with low cost and adopt to the firm in a short time. Data are analyzed with Kurusawa’s Workshop Productivity Management by Ratio Model. Also “Part Productivity”, “Machine Productivity”, “Shift Productivity” and “Capacity Usage Ratio” are added to DSS.

The main contribution of mentioned DSS is to give an opportunity that data are entered by operators in software. And other is to provide monitoring the cause and time of stopping position by coding the cause of stopping position in production. The labour productivity ratios can be easily monitored in daily, the required engineering time for entering data to the DSS is avoided and the cause of stopping position are analyzed easily with implemented DSS.

People’s beliefs about their capabilities, may influence their innovative behaviors and tendency of risk-taking. In this study, a questionnaire was delivered to 230 people working in public services to measure their perceived self-efficacy, innovativeness and risk-taking tendencies.
Correlations between variables were searched and the differences between mediums were examined using independent samples t-test. Results showed that employees’ self-efficacy and tendency towards risk-taking are more than average; whereas they have high levels of innovative behaviors. Moreover, statistically significant level of correlation detected among self-efficacy, innovativeness and risk-taking.

In this study students’ views and whether there is a significant difference between the students’ guilt and shame scores in terms of gender and students’ having or not having discipline punishment have been examined. The study included totally 150 (60 girls, 90 boys) high school students selected from 1500 students educating at the two official high schools chosen randomly in the border of Adana Municipal. 75 of these students had had discipline punishment and 75 of them hadn’t. The guilt and shame scale developed by Şahin and Şahin (1992) was used to measure the students’ guilt and shame conditions. 15 students chosen from 75 students who had discipline punishment were interviewed by using the Semi-structured Interview Schedule to gain more information about having discipline punishment. Collected data were analyzed through independent simple t test. Significant differences were found in the students’ guilt and shame scores in terms of their having or not having discipline punishment and significant differences were also found in guilt scores in terms of gender. On the other hand there weren’t significant differences in shame scores in terms of gender. The findings and views of the students who had discipline punishment were discussed and some suggestions were made.

Waste which is generated from health care providing institutions are named as hospital waste or clinical waste. Since the waste is hazardous, it must be taken under control collected safely (without giving any danger to the environment and human beings). The waste must be stored temporarily and then must be disposed permanently.

Trabzon Municipality are entirely included in this study. The management of hospital waste is investigated by observing and planned surveying in order to determine how the clinical waste is processed in the above mentioned waste treatment field. At the end of the study, it has been observed that domestic waste, glass materials, sharp objects, and infectious waste are collected separately, but unfortunately, the chemical waste has not been handled carefully and paid as much attention as possible.

Another problem that we are facing is that the sterilization capacity of waste treatment of hospital waste is not adequable. Therefore, some part of waste is disposed via sterilization process and the rest is treated the same as domestic waste.

Finally, this study indicated that there is a need of increasing the capacity of sterilization unit, and it needs to be rearranged. It is also believed that much more training for personnel and control is needed for an effective treatment of hospital waste management.

Data mining methods have been successfully applied to different fields. Aviation industry is one of these fields There is a large amount of knowledge and data accumulation in aviation industry. These data could be stored in the form of pilot reports, maintenance reports, incident reports, component reports or delay reports. This paper explains the data mining application on the component reports of an airline company in Turkey. In this study, we applied data mining functions on the component reports. The purpose of our application is to find out a rule about the warning level of the components to do correcting operation before any fault. As a result we found out a meaningful rule that presents the formulation of the warning level of the components. The rules found are tested in terms of their accuracy and reliability.

In the real life, the systems generally have multiple and confliction aims. In the airplane industry, the elements of zero defect and punctual delivery are significant for security and prestige. However, it is obvious that the rapid and intensive production for punctual delivery would increase the level of defect. In this respect, our study aimed to solve the problem of workload distribution to alternative assembly cells in an air vehicle producing factory in regards to those elements. Throughout the solution process, the technique of goal programming, which finds out the effective solution after evaluating the confliction aims at the same time, is used. With this technique, the elements of zero defect and punctual delivery are aimed to be obtained at the same time without ignoring the costs. Therefore, it was planned to have full work at alternative montage cells and to meet the demands in the same week. By using the standard work as full, the overtime at assembly cells has lessened and therefore, the production costs have decreased. In addition, by meeting the demands in the same week, the risk of delay in the delivery has been removed.

Crew scheduling problem is one of the hardest and most comprehensive problems encountered in airline
planning. In crew scheduling problem, it is aimed to find the minimum costly set of pairings in that each flight
leg is covered at least by one crew pairing. In this study, a column generation approach that is commonly used in
crew scheduling literature in which variables are dynamically generated, is used to solve the problem. The
master problem is formulated as a set covering problem while the subproblem is formulated as a shortest path
problem. Initial pairings which are sufficient to obtain a feasible solution, are produced using a linear
programming model. The master problem, sub-problem and the model used to generate initial pairings are
encoded by GAMS optimization program in an integrated manner and this integrated model is solved iteratively.
The algorithm is applied to a private airline company’s crew scheduling problem using real data and optimal
crew schedules are obtained.

In competitive economic conditions now, business enterprises use different tools to provide the competitive advantage and value maximization. One of these tools is life cycle cost analysis. The life cycle cost analysis is a cost analysis method which expresses expected cost that appears during the all life cycle which is related to existence, system or project as the same kinds of purchasing power. This analysis method is examined by different types of marketing, producer and consumer point of view and it is used as a strategical tool during decision process. In this study the life cycle cost analysis is explained with all aspects and the practice examples related to how the life cycle cost analysis in procurement process with consumer point of view as a strategical decision are given.

The role of tourism on economic growth in the long-run for Turkey is examined in
this paper for the period of 1992:1-2007:2. The tourism-led growth hypothesis is confirmed through Johansen co-integration and error correction-augmented Granger causality tests. The results demonstrate that during the last 15 years tourism stimulated economic growth in Turkey.
