Conference Object Citation Count: 3Error density metrics for business process model(2009) Mısra, Sanjay; Misra,S.; Computer EngineeringIn this paper, metrics for business process model (BPM), are proposed, which are capable to measure the usability and effectiveness of BPMs. The proposed model is adapting error density metrics to BPMs by considering the similarities between the conceptual characteristics of BPMs and software products. We applied seven software metrics for evaluating quality of business processes/process models. Results show that our metrics help the organization to improve their process, as weighted measurements are indicators for unexpected situations/behaviour for business processes. © 2009 IEEE.Conference Object Citation Count: 0Neuronavigation systems and passive usage problem;(Institute of Electrical and Electronics Engineers Inc., 2017) Çağıltay, Nergiz; Tokdemir, Gül; Aydın, Elif; Tokdemir,G.; Maras,H.; Tonbul,G.; Topallı, Damla; Department of Electrical & Electronics Engineering; Computer Engineering; Software Engineering; Information Systems EngineeringNowadays, neuronavigation systems are used in brain surgery procedures, known as a technology to help the surgeon during the operational period. However, the surgeons have faced several problems with the existing systems. Some of these problems are related to the systems software and user interfaces. In this study, such problems are examined and the 'Passive Usage' term is added to the literature by establishing a connection between the problems of endoscopic surgical procedures and similar issues occurred in other domains. The passive usage problem is generalized on different domains for the first time with this study. The results of the study expected to gather up the similar passive usage problems experienced in different domains. Accordingly, the methodologies and studies that are conducted in different research areas may lead to eliminate the Passive Usage problems efficiently. © 2016 IEEE.Conference Object Citation Count: 0Simulation based surgical education programs and hand performance;(Institute of Electrical and Electronics Engineers Inc., 2017) Topallı, Damla; Topalli,D.; Cagiltay,N.E.; Tonbul,G.; Information Systems EngineeringThe performance of the left- and right-hands of a person may be different from each other. In general, people use one hand with a superior performance compared to the other hand where that hand is preferred for performing daily activities. It is critical to understand their preference for right or left hand use, especially in cases where the skills should be improved to use both hands precisely in activities required special abilities such as endoscopic surgical operations. A better understanding of these cases will improve the quality of existing surgical education programs, and make a major contribution specifically in designing, improving and managing of simulation-based instructional technologies. In this study, the right- and left-hand preferences (handedness) of people are analyzed from the literature and a simulation-based experimental study is conducted in order to examine the performance differences of the participants while using their right and left hands. The results of this study aimed to guide the curriculum designers and instructional system developers for better designing and developing simulation-based surgical education programs. © 2016 IEEE.
