BACKGROUND Recently, nonopioid-based treatment modalities have been used to improve analgesia and decrease opioid-related side effects after surgery. Transversus abdominis plane (TAP) block and local infiltration of the surgical wound are commonly used multimodal analgesia techniques after abdominal surgery; however, few studies have compared the(More)
Recently, discrete part manufacturing systems have encountered more impending requests for adaptability and flexibility in order to efficiently survive the increasing dynamics of manufacturing environment. Although featurebased computer-aided process planning plays a vital role in automating and integrating design and manufacturing for efficient production,(More)
Several open control architectures have been proposed to enable the incorporation of new technologies into existing CNC controllers. However, complex interfaces and communications among heterogeneous hardware and software platforms have yet to be resolved to reduce development time and cost. We propose a piece of kernel software that facilitates the(More)
BACKGROUND Peripheral nerve injury results in chronic neuropathic pain characterized by allodynia and/or spontaneous pain. It has been suggested that activation of mitogen-activated protein kinases such as extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) contribute to the neuropathic pain. OBJECTIVES We investigated if(More)
Distributed shop floor control is likely to become a key component of 21st century manufacturing technology. The interest in distributed control arises from the promise of increased flexibility, reliability, and tolerance to the uncertainty that exists in the shop floor environment. However, the communicational complexities involved in the integration of(More)
Cytochrome P450 3A4 (CYP3A4) enzyme is responsible for the metabolic activation and inactivation of the majority of clinically used drugs in human liver and intestines. Recent studies have increasingly implicated various inflammatory stimuli to cause changes in the activities and expression levels of CYPs. However, the underlying mechanisms are largely(More)
In paid search advertising on Internet, advertisers bid for specific keywords. Consumer involvement affects a consumer’s purchase intention. However, there has been no research on selecting keywords in paid search advertising depending on consumer involvement from the advertisers’ perspective. Our paper investigates the effects of several factors including(More)
PURPOSE Opioid-based intravenous patient-controlled analgesia (IV-PCA) is a popular method of postoperative analgesia, but many patients suffer from PCA-related complications. We hypothesized that PCA was not essential in patients undergoing major abdominal surgery by minimal invasive approach. METHODS Between February 2013 and August 2013, 297 patients(More)
The Fas (CD95, APO-1) receptor is a transmembrane cell surface receptor that mediates apoptosis in many cell types when bound by the Fas ligand or cross-linked by agonistic anti-Fas antibodies. Fas activation engages a potent and rapid signaling mechanism in a variety of cell types. In the present study, we have investigated the effects of Fas receptor(More)
Although many conceptual structures for shop ¯oor control have been proposed, their implementation methodologies have not been satisfactorily achieved yet due to the cost and time required for developing new control software and modifying the existing software. This paper suggests a Petri-net-based tool to rapidly develop a task execution module in the(More)
