DNA microarray is a high-throughput biomedical technology that monitors gene expression for thousands of genes in parallel. The abundance and complexity of the gene expression data have given rise to a requirement for their systematic management and analysis to support many laboratories performing microarray research. On these demands, we developed Xperanto for integrated data management and analysis using user-friendly web-based interface. Xperanto provides an integrated environment for management and analysis by linking the computational tools and rich sources of biological annotation. With the growing needs of data sharing, it is designed to be compliant to MGED (Microarray Gene Expression Data) standards for microarray data annotation and exchange. Xperanto enables a fast and efficient management of vast amounts of data, and serves as a communication channel among multiple researchers within an emerging interdisciplinary field.

In the age where the Internet changes everything, even the earth has become flat. The boarders between nations, locations, times, and industries are not meaningful, and no single company can do the whole process well. Therefore, various types of 'Value network' and 'Relation web' emerge for moving first and learning fast. Both the relationship maturity model (RMM) proposed and the partnership management initiatives at SKT demonstrate that the concept is important, and that the final goal can be reached only through a series of critical outcome at each phase. In particular, recognizing as core infrastructures various online/offline channels, deep trust, and rich communications is an important finding for a successful relationship management. Also, related literatures suggest the following key factors to be influential in more than two phases: professionalism including expertise, similarity, channel infrastructure, trustful/trustworthy, and absorptive capacity. Based on these findings, future efforts need to be put on the research & development of related measurement and management tools. It is hoped that more dance with their partners through these efforts.

Background: Cyclic guanosine monophosphate (cGMP) and opioid receptors are involved in the modulation of nociception. Although the opioid receptors agonists are active in pain, the effect of an phospodiesterase inhibitor (zaprinast) for increasing the level of cGMP has not been thoroughly investigated at the spinal level. This study examined the effects of intrathecal zaprinast and morphine in a nociceptive test and we also examined the nature of the pharmacological interaction after the coadministration of zaprinast with morphine. The role of the nitric oxide (NO)-cGMP-potassium channel pathway on the effect of zaprinast was further clarified. Methods: Catheters were inserted into the intrathecal space of male SD rats. For the induction of pain, $50{\mu}l$ of 5% formalin solution was applied to the hindpaw. Isobolographic analysis was used for the evaluation of the drug interaction between zaprinast and morphine. Furthermore, NO synthase inhibitor ($_L-NMMA$), guanylyl cyclase inhibitor (ODQ) or a potassium channel blocker (glibenclamide) were intrathecally administered to verify the involvement of the NO-cGMP- potassium channel pathway on the antinociception effect of zaprinast. Results: Both zaprinast and morphine produced an antinociceptive effect during phase 1 and phase 2 in the formalin test. Isobolographic analysis revealed a synergistic interaction after the intrathecal administration of the zaprinast-morphine mixture in both phases. Intrathecal $_L-NMMA$, ODQ and glibenclamide did not reverse the antinociception of zaprinast in either phase. Conclusions: These results suggest that zaprinast, morphine and the mixture of the two drugs are effective against acute pain and they facilitated pain state at the spinal level. Thus, the spinal combination of zaprinast with morphine may be useful for the management of pain. However, the NO-sensitive cGMP-potassium channel pathway did not contribute to the antinocieptive mechanism of zaprinast in the spinal cord.

This study aims to explain the cause of price differences of bi-national products based on consumer response of product type, distribution channel, and consumer nationality, respectively. Specifically this study investigated whether price discount and distribution channel affect consumer evaluation by luxury and non-luxury product type. In the case of bi-national product toward the non-luxury, price discount had positive influence on preference, regardless of distribution channel. By revealing the influence of price discount on bi-national products on consumer response of product type and distribution channel respectively, the study suggests meaningful implications for the strategic management of bi-national products.

This study was to examine the operation strategy of terrestrial broadcasting system on channel image and N-screen service. Nowadays, terrestrial broadcasting system provides video streaming service based on internet. In other words, terrestrial broadcasting system provides N-screen service through TV-PC-Smart phone-Tablet PC. But it is different for terrestrial broadcasting system to analysis the choice criterion of program. Only, channel image of terrestrial broadcasting system expanded into N-screen. Finally, channel image of terrestrial broadcasting system is the competition strategy. It is necessary for terrestrial broadcasting system to prepare the strategy of program choice for users, original contents, new platform and service in connection with N-screen.

In this investigation, we prepared a 1 and 3-parallel serpentine single PEMFC, which has an active area of $100\;cm^2$ and a flow channel cross section of $1{\times}1mm$. Distribution and transport of water in a non-operating PEMFC were observed by varying flow types and the flow rates (250, 400, and 850 cc/min). This investigation was performed at the neutron imaging facility at the CO1d Neutron RAdiography facility (CONRAD), HMI, Germany of which the collimation ratio and neutron fluence rate are 250, $1{\times}10^{6}n/s/cm^2$, respectively. The neutron image was continuously recorded by a scintillator and lens-CCD coupled detector system every 10 seconds. It has been observed that although the distilled water was supplied into the cathode channel only, the neutron image showed a water movement from the cathode to the anode channel. The water at the cathode channel was completely discharged as soon as the pressurized air was supplied. But the water at the anode channel was not easily removed by the pressurized air except for the 3-parallel serpentine type with 850cc/min of air flow rate. Moreover, the water at the MEA wasn't removed for any of the cases.
