VapormateTM, the new gas formation of ethyl formate(EF) with carbon dioxide, is an MB(methyl bromide) alternative fumigant for grains and perishable commodities especially to control quarantine pest. To gain systematic efficacies of VapormateTM, vaporized gases in Tedlar bag were collected from liquefied gases in cylinder. Vaporized gases were used for collecting efficacy data to Tetranychus urticae, two-spotted spider mite, for 6hr at 26± 1℃. When applied 25, 51, 77 and 102 ml/L of vaporized gas for 6hr, mortality of T. urticae female adult were 83.3, 97.8, 100, and 100%, respectively, at 24hr after fumigation. Also, at 77 and 102 ml/L of vaporized gas for 4hr treatment at 26± 1℃, the mortality of T. urticae female was 96.7 and 97.8%, respectively. This preliminary result may help to understand further scaled-up VapormateTM fumigation applied with different type of commodities.

<P>To evaluate the feasibility of selecting a mobilization regimen based on the response to induction therapy, we retrospectively analyzed 179 multiple myeloma patients who underwent stem cell mobilization. In comparison with patients who achieved at least a very good partial response (VGPR) to induction therapy and received granulocyte-colony stimulating factor (G-CSF) alone and patients who did not achieve a VGPR and received cyclophosphamide (CY)+G-CSF, treatment-related toxicity was greater and neutrophil engraftment was slower in the CY than the G-CSF group. The rate of requisite mobilization (2.0x10(6)/kg) was similar in both groups. Overall and progression-free survival was not different between patients in the G-CSF group and patients who achieved at least VGPR and received CY+G-CSF. In conclusion, response-adapted selection of a mobilization regimen is appropriate. G-CSF alone should be the preferred treatment for patients who achieved at least a VGPR to induction therapy.</P>

As the patterns of PCB(Printed Circuit Board) are becoming denser and more complex, various automatic visual inspection algorithms to detect circuit defects have been proposed. These algorithms, however, are classified under two methods-referencing method and nonrefrencing method. This paper is based on referencing method. Two major steps are proposed in this paper. First, the lower and upper limits of circuit-width and the lower limit of narrow are determined from ideal images. Second, these limits are compared with target images, and various defects are detected and reported. Using bit operations, the pure inspection time of the proposed algorithm is less then one second, and they alignment error of one pixel is allowed.

<P><B>Abstract</B></P> <P>In this study, we evaluate lanthanum strontium cobalt ferrite (LSCF) surface-coated with lanthanum nickelate (LNO) fabricated by aerosol-assisted chemical vapor deposition (AACVD) for application in solid oxide fuel cells (SOFCs). The AACVD method successfully produces LNO in the desired composition and crystal structure. The deposited LNO is confirmed to form a dense and uniform layer along the nano-porous LSCF support. The LSCF with an optimal amount of LNO surface clearly enhances the SOFC performance, showing a power increase of approximately 60% at 600 °C in our experiment. This enhancement results from the reduction of both ohmic and polarization resistance, presumably due to improved cathodic surface kinetics and current collection. This AACVD LNO-treatment is also confirmed to be effective in improving long-term stability, significantly suppressing the power decrease observed in an untreated sample.</P>
