Hodhod and Colleagues Use Deep Learning to Diagnose Pneumonia

A new study by TSYS School computer science professor Rania Hodhod and research colleagues from Princess Nourah Bint Abdulrahman University (Saudi Arabia) and Ain Shams University (Egypt) extends the academic literature demonstrating how artificial intelligence, in particular deep learning, has proven to be efficient in medical diagnosis. The study, which appears in the current issue of Electronics, introduces a new hybrid deep learning model for pneumonia diagnosis based on chest CT scans. The core of the model developed by Hodhod and colleagues includes an expectation-maximization algorithm that works to extract the regions of interest from the chest CT scans while also preventing it from learning trivial solutions. To test their model, the researchers examined a dataset of chest X-rays for pneumonia from the Kaggle website. The data set contains 5,856 images with 1,583 normal cases and 4,273 pneumonia cases, with an imbalance ratio of 0.46. To better balance the data, Hodhod and colleagues implemented several operations including zooming, flipping, shifting and rotation, ultimately resulting in an imbalance ratio of only 0.028. The computational analysis of the results show that the proposed model is quite promising, as it provides an average accuracy value of 98.6 percent.

Grant Hits Ground Running as New Turner College Marketing Intern

The Turner College's new marketing intern Lizzy Grant , a senior marketing major from Newnan who previously attended Gordon State College, where she played varsity soccer, and is scheduled to graduate from the Turner College in May of 2024, has hit the ground running in her new position. She recently played a large role in the creation of a video tour of the Synovus Center, the main campus home of the Turner College. The video helps to guide new students on where to go in the building and who they can talk to if they help. The video showcases the Student Services Center, the main lobby, and more. The video is played as part of a loop on video screens placed throughout the Synovus Center. Lizzy's list of activities at CSU is impressive. She is the Treasurer of the Turner College's Marketing Club, the President of Marketing for the Turner College's chapter of the Financial Management Association, and an Ambassador for the Turner College.

Jung Exploring Influence of Confucianism on Luxury Brand Performance in China, Japan and South Korea

In a recent chat with Turner Business , Turner College professor of marketing Sungwoo Jung made the point that luxury brands are gaining the degree of influence in many developing countries that they enjoy now in developed countries. He has been pondering this issue as part of his international marketing research program, which typically focuses on advertising, pioneering advantages and multi-cultural analysis. Currently, Jung is concentrating his energies on a cross-cultural analysis of brand equity that highlights luxury brands’ performance. His research finds that China, Japan and South Korea have each seen an increase in market share for luxury brands in recent years. As Jung explained to Turner Business , “These three countries share a common philosophical background – Confucianism.” With that point in mind, Jung and his coauthors are currently engaged in an investigation of how Confucianism influences consumer behavior in these three Asian countries, and how that behavior im

Turner College Grad Publishes Academic Study on Corporate Culture and Strategy

Former Turner College student Tamara Todorova , now an associate professor of economics at American University in Bulgaria (AUB), recently published a study on corporate culture and strategy. Todorova earned an MBA from the Turner College in 1996 and then went on to earn a doctorate in international economics from the University of Economics - Varna in 2001. She has been on the faculty at AUB since August of 2000. Todorova's study, which appears in the current issue of the International Journal of Business Performance Management , investigates how corporate culture helps to economize on the transaction costs of internal organization. As she explains, the dimensions of corporate culture that assist in this task include increasing trust and reducing intrafirm opportunism. Todorova's study demonstrates that setting common goals and a common direction reduces the sizeable costs of internal organization. Tamara's prior research appears in Economics of Transition , International
