DR-TCP is a new TCP implementation structure that focuses on reconfigurability and extensibility. To make TCP reconfigurable, we re-implement Reno based on a state machine model so that reconfiguration can be done by just modifying state transition table. As a result, DR-TCP can support dynamic reconfiguration without loss of connec-tivity and its overhead(More)
which permits unrestricted noncommercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Background: The purpose of this study was to compare the physical activity and caloric intake trends of lipid-lowering drug users with those of non-users among Korean adults with dyslipidemia. Methods: This study was a(More)
Modern vehicles are evolving with more electronic components than ever before (In this paper, “vehicle” means “automotive vehicle.” It is also equal to “car.”) One notable example is graphical processing unit (GPU), which is a key component to implement a digital cluster. To implement the digital cluster that(More)
A 75-year-old Korean man was referred to our hospital with cramping abdominal pain. His chest X-ray showed an abnormal air shadow above the diaphragm, and computed tomography showed an abdominal viscera in the pericardium. We performed surgery and confirmed peritoneopericardial diaphragmatic hernia with small bowel strangulation. Postoperative course was(More)
Android has been extended gradually from mobile to other IT fields. But, Android which pursues an open environment has become a main target of the attackers and malicious codes have rapidly increased. The problem is that it is difficult for users to recognize malicious applications. In this paper, to solve this problem, TrustZone developed by ARM is used in(More)
Several commodity operating systems have used kernel extensions to extend or replace their functionalities. Generally, since the kernel extensions are executed in the same address space with the kernel, a mere fault in the extensions may lead the whole system to be corrupted. So naturally, studies on the kernel extension are mainly proposed with the goal of(More)
