Strategic IT management is increasingly concerned with requirements from regulatory bodies. This conformance part of IT management complements the classic performance side. Ideally both are integrated into IT Governance of an enterprise or organization. With the need to prove compliance with a wide diversity of laws and rules for IT systems (technology, processes, rules) the demand for proven support methods grows. Specifically best practice models are beginning to gain awareness and acceptance for IT Audits and for the less formal IT Assurance projects. The Control Objectives for Information and Related Technology (CobiT) reference model is increasingly being discussed as a framework of choice for IT Audits and IT Assurance. This chapter introduces requirements for IT Audits and IT Assurance projects and discuss the boundaries of applying the CobiT IT Assurance Guide in such environments.

Management Issues

Optimized of management Information Technology related aspects of both internal and external software such as networking, it can not be done sporadically personalized level management or policy makers. IT management issues has been experiencing a transition from technology issues into problems of management and governance. It was triggered by the increasing dependence and the need for the field of Information Technology. In today's modern era of information technology should be managed as well as manage other assets as a strategy for continuity of service of an agency / company.However along with the requirement also escalate issues of how to ensure that information technology is applied in accordance with the needs and functions. As well important how to control the transparency of the procurement of Information Technology is not abused and that the application is not appropriate. For it was imperative for government agencies to have a reference model suitable of IT Governance as required and expected. This study successfully identified the presence of 3 (three) CobIT 5 process to be used as the IT Governance models that can be applied, they are; EDM02, EDM03, and EDM05.

Zusammenfassung: Das I/E-Modell (“Internal/External Frame of Reference Model”) von Marsh (1986) postuliert, dass Schülerinnen und Schüler dimensionale Vergleiche der eigenen Leistungen in einem Fach mit den Leistungen in einem anderen Fach anstellen. Diese Vergleiche führen dazu, dass z. B. Schüler mit guten Leistungen in Mathematik ihre verbalen Fähigkeiten niedriger einschätzen. Gegenstand dieser Untersuchung mit N = 1114 Probanden ist die Frage, ob die Überzeugungen von Personen zum Zusammenhang von mathematischer und verbaler Begabung die Effekte dimensionaler Vergleiche moderieren. Analysen zeigten die Bedeutung der Begabungsüberzeugungen der Schülerinnen und Schüler: Negative Zusammenhänge zwischen den Fachleistungen in einem Fach und dem akademischen Selbstkonzept in einem anderen Fach ergaben sich insbesondere für Personen, die annehmen, dass Begabung domänenspezifisch ist, man also entweder mathematisch oder sprachlich begabt ist. Für Schüler mit eher wenig spezifischer Begabungsüberzeugung ergaben sich geringere Effekte dimensionaler Vergleiche.

Abstract:In 1987, the American Rheumatism Association issued a set of criteria for the classification of rheumatoid arthritis (RA) to provide a uniform definition of RA patients. Fuzzy set theory and fuzzy logic were used to transform this set of criteria into a diagnostic tool that offers diagnoses at different levels of confidence: a definite level, which was consistent with the original criteria definition, as well as several possible and superdefinite levels. Two fuzzy models and a reference model which provided results at a definite level only were applied to 292 clinical cases from a hospital for rheumatic diseases. At the definite level, all models yielded a sensitivity rate of 72.6% and a specificity rate of 87.0%. Sensitivity and specificity rates at the possible levels ranged from 73.3% to 85.6% and from 83.6% to 87.0%. At the superdefinite levels, sensitivity rates ranged from 39.0% to 63.7% and specificity rates from 90.4% to 95.2%. Fuzzy techniques were helpful to add flexibility to preexisting diagnostic criteria in order to obtain diagnoses at the desired level of confidence.

In this paper, a commercial CFD code, ANSYS-Fluent has been used to investigate the effect of mesh number generated in the computed domain on the CFD aerodynamic performances of a container ship. A full-scale model of the 1200TEU container ship has been chosen as a reference model in the computation. Five different mesh numbers for the same dimension domain have been used and the CFD aerodynamic performances of the above water surface hull of the ship have been shown. The obtained CFD results show a remarkable effect of mesh number on aerodynamic performances of the ship and the mesh convergence has been found. The study is an evidence to prove that the mesh number has affected the CFD results in general and the accuracy of the CFD aerodynamic performances in particular.
