  • In order to develop alloy resistance in aggressive sulphat ion, the corrosion behavior of metallic glasses $Ni_{92{\cdot}3}Si_{4.5}B_{32}$, $Ni_{82,3}Cr_7Fe_3Si_{4.5}B_{3.2}$ and $Ni_{75.5}Cr_{13}Fe_{4.2}Si_{4.5}B_{2.8}$ (at %) at different concentrations of $H_2SO_4$ solutions was examined by electrochemical methods and Scanning Electron Microscope (SEM) and X-ray Photoelectron Microscopy (XPS) analyses. The corrosion kinetics and passivation behavior was studied. A direct proportion was observed between the corrosion rate and acid concentration in the case of $Ni_{92{\cdot}3}Si_{4.5}B_{32}$ and $Ni_{75.5}Cr_{13}Fe_{4.2}Si_{4.5}B_{2.8}$ alloys. Critical concentration was observed in the case of $Ni_{82,3}Cr_7Fe_3Si_{4.5}B_{3.2}$ alloy. The influence of the alloying element is reflected in the increasing resistance of the protective film. XPS analysis confirms that the protection film on the $Ni_{92{\cdot}3}Si_{4.5}B_{32}$ alloy was NiS which is less protective than that formed on Cr containing alloys. The corrosion rate of $Ni_{82,3}Cr_7Fe_3Si_{4.5}B_{3.2}$ and $Ni_{75.5}Cr_{13}Fe_{4.2}Si_{4.5}B_{2.8}$. alloys containing 7% and 13% Cr are $7.90-26.1{\times}10^{-3}$ mm/y which is lower about 43-54 times of the alloy $Ni_{92{\cdot}3}Si_{4.5}B_{32}$ (free of Cr). The high resistance of $Ni_{75.5}Cr_{13}Fe_{4.2}Si_{4.5}B_{2.8}$ alloy at the very aggressive media may due to thicker passive film of $Cr_2O_3$ which hydrated to hydrated chromium oxyhydroxide.

  • Purpose: To identify the clinical and epidemiological characteristics of human metapneumovirus infections (hMPV) in children compared to respiratory syncytial virus A (RSV A) and B (RSV B). Method: A retrospective review of medical records was performed in 36 patients with hMPV infection, 106 with RSV A infection, and 51 with RSV B infection, from September 2007 to July 2012. Results: The peak incidence of hMPV infection was observed in May, whereas for RSV infections in November and December. hMPV infection occurred in older patients compared to RSV A and B infection ($29.9{\pm}32.5$ months vs. $13.6{\pm}15.4$ months, P<0.001; $29.9{\pm}32.5$ months vs. $12.1{\pm}13.5$ months, P<0.001, respectively). hMPV infection was more often associated with fever compared to RSV A (97.2% vs. 67.9%, P<0.001), while wheezing was less frequent compared to RSV A and B infection (16.7% vs. 47.2%, P=0.001; 16.7% vs. 37.3%, P=0.037, respectively). hMPV infection was more often diagnosed as pneumonia compared to RSV A infection (72.2% vs. 50.0%, P=0.047) while bronchiolitis was less frequent than in RSV A (5.6% vs. 34.9%, P=0.001) or RSV B infection (5.6% vs. 29.4%, P=0.006). In addition, intravenous antibiotic was more often prescribed for patients with hMPV infection than those with RSV A and B (69.4% vs. 39.6%, P=0.002; 69.4% vs. 43.1, P=0.015, respectively). Conclusion: This study identified characteristics of hMPV infection compared to RSV A and B infection. Seasonality in spring, higher age group, and higher proportion of pneumonia in hMPV infections may be a useful guide for management of respiratory viral infections in children.

  • By standardized method, Bacillus subtilis BGA, Bacillus cereus var. mycoides ATCC 11778, and Micrococcus luteus ATCC 9341 were seeded on the muller hinton agar (Difco) plate, and pH was adjusted to 6.0, 7.2, and 8.0. Five agar plates, B. subtilis (pH 6.0), B. cereus (pH 6.0), B. subtilis (pH 7.2), B. subtilis (pH 8.0), and M. luteus (pH 8.0), were employed as test plates of modified EEC 4-plate method. Oxytetracycline (OTC) with a diet was orally administered to flounder, Paralichthys olivaceus, at 100 mg/kg once a day. After oral administration, modified EEC 4-plate method by the three screening test using muscle-direct, extraction-disk and direct-disk methods was conducted for 3 fish at 1, 3, 5, 10, 15, 20, 25 and 30 days. Muscle-direct treatment of B. subtilis (pH 6.0) was found to be dubious positive (${\pm}$) at the 1st day after the administration; thereafter, it was found to be negative to the last day of the experiment. Extraction-disk and direct-disk treatment of B. subtilis (pH 6.0) were found to be negative from the 1st day to the last day after the administration. B. subtilis (pH 7.2), B. subtilis (pH 8.0), and M. luteus (pH 8.0) by the three screening tests, were found to be negative all the way after the administration. On the other hand, B. cereus (pH 6.0) by the three screening tests was clearly found to be positive for the first 15 days after the administration, and then muscle-direct and direct-disk treatment of B. cereus (pH 6.0) were found to be dubious positive at 20th days after the administration. However extraction-disk treatment of B. cereus (pH 6.0) was clearly found to be negative at the same stage; thereafter, the three screening tests of B. cereus (pH 6.0) were found negative to the last of the experiment. These findings showed that to have equal sensitivity to those determination for the residual detection of OTC, and also confirmed that B. cereus was effective test organism for the monitoring of OTC.

  • This paper describes a methode to extract yellow pigment from curcuma and turmeric containing natural color curcumin whose target color indexes of L, a, and b were 87.0 7.43, and 88.2, respectively. The pH range and extraction temperature used for the reaction surface analysis method were from pH 3 to pH 7 and between 40 and $70^{\circ}C$, respectively for both natural products. A central synthesis planning model combined with the method was used to obtain optimal extraction conditions to produce the color close to target. Results and regression equations show that the color space and difference of curcuma and turmeric have the greatest influence on the value. In the case of curcuma, the optimum conditions to satisfy all of the response theoretical values of color coordinates of L (74.67), a (5.69), and b (70.08) were at the pH and temperature of 3.43 and $54.8^{\circ}C$, respectively. The experimentally obtained L, a, and b, values under optimal conditions were 72.92, 5.32, and 72.17, respectively. For the case of turmeric, theoretical numerical color coordinates of L, a, and b, under the pH of 5.22 and temperature of $50.4^{\circ}C$ were 82.02, 7.43, and 72.86 respectively. Whereas, the experiment results were L (81.85), a (5.39), and b (71.58). Both cases showed an error range within 1%. Therefore, it is possible to obtain a low error rate when applying the central synthesis planning model to the reaction surface analysis method as an optimization process of the dye extraction of natural raw materials.

  • Two new carborane complexes containing closo- or nido-carborane diphosphine ligands with the formula: complex $[Hg(7,8-(PPh_2)_2-7,8-C_2B_9H_{10})_2]$ $CH_2Cl_2$ (1) and $[Ag_2({\mu}-Cl)_2(1,2-(P^iPr_2)_2-1,2-C_2B_{10}H_{10})_2]$ (2) have been synthesized and characterized by elemental analysis, 1H and 13C NMR spectroscopy and X-ray structure determination. The X-ray structure analyses revealed that the carborane diphosphine ligand was degraded from closo-1,2-$(PPh_2)_2-1,2-C_2B_{10}H_{10}$ to nido-[$7,8-(PPh_2)_2-7,8-C_2B_9H_{10}]^-$ in complex 1, while the closo nature of the starting ligand $1,2-(P^iPr_2)_2-1,2-C_2B_{10}H_{10}$ was retained in complex 2. In either of the two complexes, the carborane diphosphine ligand was coordinated bidentately to the Hg(II) or Ag(I) center through its two phosphorus atoms, therefore forming a five-member cheating ring between the carborane ligand and the metal center. The coordination geometry of the metal atom is distorted tetrahedron formed by $P_4$ unit in complex 1 and $P_2Cl_2$ unit in complex 2, respectively.

  • We introduce a novel and versatile approach for preparing self-assembled nanoporous multilayered films with antireflective properties. Protonated polystyrene-block-poly (4-vinylpyrine) (PS-b-P4VP) and anionic polystyrene-block-poly (acrylic acid) (PS-b-PAA) block copolymer micelles (BCM) were used as building blocks for the layer-by-layer assembly of BCM multilayer films. BCM film growth is governed by electrostatic and hydrogen-bonding interactions between the oppositely BCMs. Both film porosity and film thickness are dependent upon the charge density of the micelles, with the porosity of the film controlled by the solution pH and the molecular weight (Mw) of the constituents. PS7K-b-P4VP28K/PS2K-b-PAA8K films prepared at pH 4 (for PS7K-b-P4VP28K) and pH 6 (for PS2K-b-PAA8K) are highly nanoporous and antireflective. In contrast, PS7K-b-P4VP28K/PS2K-b-PAA8K films assembled at pH 4/4 show a relatively dense surface morphology due to the decreased charge density of PS2K-b-PAA8K. Films formed from BCMs with increased PS block and decreased hydrophilic block (P4VP or PAA) size (e.g., PS36K-b-P4VP12K/PS16K-b-PAA4K at pH 4/4) were also nanoporous. Furthermore, we demonstrate that the nanostructured electrochemical sensors based on patterning methods show the electrochemical activities. Anionic poly(styrene sulfonate) (PSS) layers were selectively and uniformly deposited onto the catalase (CAT)-coated surface using the micro-contact printing method. The pH-induced charge reversal of catalase can provide the selective deposition of consecutive PE multilayers onto patterned PSS layers by causing the electrostatic repulsion between next PE layer and catalase. Based on this patterning method, the hybrid patterned multilayers composed of platinum nanoparticles (PtNP) and catalase were prepared and then their electrochemical properties were investigated from sensing $H_2O_2$ and NO gas. This study was based on the papers reported by our group. (J. Am. Chem. Soc. 128, 9935 (2006); Adv. Mater. 19, 4364 (2007); Electro. Mater. Lett. 3, 163 (2007)).

  • In order to understand the effect of hydrostatic pressure (HP) on Bacillus subtilis isolated from makgeolli, the survival of B. subtilis after HP treatment (400 MPa for 5 min) in various substrates including phosphate buffer, tryptone soya broth at pH 7 and 4, and makgeolli at pH 4 was evaluated depending on bacterial forms (spores and vegetative cells) and adaptation conditions ($25^{\circ}C$ for 3 h, or $10^{\circ}C$ for 24 h). Spores were generally resistant to HP (<1 log reduction) regardless of conditions. In contrast, vegetative cells were generally susceptible to HP (up to 3 log reduction-except makgeolli) and were more susceptible after 3 h at $25^{\circ}C$ compared to 24 h at $10^{\circ}C$. In vegetative cells inoculated makgeolli (7 log CFU/mL), the colonies were not detected after 24 h at $10^{\circ}C$. Consequently, B. subtilis in makgeolli easily existed as spores and the spores were resistant to HP. Results demonstrate that HP was more promising in the inactivation of vegetative cells.

  • To investigate clonal variations of recombinant Chinese hamster ovary(rCHO) clones in response to culture pH and temperature, serum-free suspension cultures of two antibody-producing CHO clones(clones A and B), which were isolated from the same parental clone by the limiting dilution method, were performed in a bioreactor at pH values in the range of 6.8-7.6, and two different temperatures, $33^{\circ}C\;and\;37^{\circ}C$. In regard to cell growth, clone A and clone B displayed similar responses to temperature, although their degree of response differed. In contrast, clones A and B displayed different responses to temperature in regard to antibody production. In the case of clone A, no significant increase in maximum antibody concentration was achieved by lowering the culture temperature. The maximum antibody concentration obtained at $33^{\circ}C$(pH 7.4) and $37^{\circ}C$(pH 7.0) were $82.0{\pm}2.6$ and $73.2{\pm}4.1{\mu}g/ml$, respectively. On the other hand, in the case of clone B, an approximately 2.5-fold increase in maximum antibody concentration was achieved by lowering the culture temperature. The enhanced maximum antibody concentration of clone B at $33^{\circ}C$($132.6{\pm}14.9{\mu}g/ml$ at pH 7.2) was due to not only enhanced specific antibody productivity but also to prolonged culture longevity. At $33^{\circ}C$, the culture longevity of clone A also improved, but not as much as that of clone B. Taken together, CHO clones derived from the same parental clone displayed quite different responses to culture temperature and pH with regards antibody production, suggesting that environmental parameters such as temperature and pH should be optimized for each CHO clone.
