Item A MODEL FOR EVALUATION OF USER TRUST TO CLOUD SERVICE PROVIDERS(2017-04-02) İnceler, Deniz Koray; Bostan, Atila; Turhan, ÇiğdemThis thesis reviews the trust on the cloud computing environment from the viewpoint of cloud service users by developing a multiview metric to evaluate diverse cloud service providers. The approaches to user trust concept are studied to show that evaluation of trust necessitates both technical and non-technical approaches that need to be assessed together to obtain an all-in exclusive solution. Trust has been studied in six different domain approaches to fulfill the requirements of cloud users. The motivation in this study is to develop a trust-scale that consists of metrics which are based on observable facts. Such a trust-scale is expected to help cloud users in their trust evaluation of different cloud service providers. Ultimately, the trust-scale is formed with its metrics and subparts and fine-tuned by using the survey data as to map the expert point of view. The proposed evaluation methodology and scale helps cloud users in their trust assessment of diverse cloud service providers using observable and quantifiable metrics. As a result, the accuracy tests of the metric that is developed in this study resulted as %95 accurate with the expert point-of-view. This accuracy test result points out that the trust scale is capable to evaluate trust at a sufficient level of trust.Item ANALYZING THE ADMINISTRATIVE AND STAFF REQUIREMENTS OF E-GOVERNMENT SERVICES AND PRIORITIZING THE DEPLOYMENT WITH MODULAR DESIGN: IRAQI CORRECTION SERVICES CASE STUDY(2022-02-28) Alameri, Mohammed; Bostan, Atila; Akman, İbrahimIraqi Correction Services (ICS) is a department within the Ministry of Justice.

Iraqi government, like other governments, tried to benefit from e-government services. Vocational schools are one of the formations affiliated to the Ministry of Education in Iraq and specifically to the General Directorate of Vocational Education which is one of the largest directorates in this ministry. Its main objective is to educate and graduate students in the professional and vocational fields. Despite the benefits of e government paradigm, still there is no clear vision for how to adopt it in the education sector. This work presents which and how e-services should be developed and deployed in Iraqi vocational schools by analyzing the requirements and preferences of the service contributors and consumers. We have identified eight stakeholders in vocational schools and developed eight different questionnaires for each. They were verified and implemented then hypotheses were conducted to extract information from the respondents. After analyzing the hypotheses, it was found that the human resource allocation was important for the participants because of its effect in reducing time and effort for school’s administration and staff. In addition, automatic access to the results of the examinations is found to present the highest priority and importance among other services for the families of students. For students, automating registration process is reported to have high priority for them. The results also revealed that most of the participants prefer website services as the main technology to communicate with vocational schools. .
