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)
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 feature-based computer-aided process planning plays a vital role in automating and integrating design and manufacturing for efficient(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)
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)
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)

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)
Balloon whisk-like and flower-like SiOx tubes with well-dispersed Sn and joining countless SiOx loops together induce intense luminescence characteristics in substrate materials. Our synthetic technique called "direct substrate growth" is based on pre-contamination of the surroundings without the intended catalyst and source powders. The kind of supporting(More)
Parallel-plate capacitors were fabricated using a printed multi-layer structure in order to determine the effects of particle size and solvent on the capacitance. The conductive-dielectric-conductive layers were sequentially spun using commercial inks and by intermediate drying with the aid of a masking polymeric layer. Both optical and scanning electron(More)
