  • Interface reaction between LSMC and YSZ is discussed with chemical composition of LSMC. The reac-tivity between LSMC and YSZ increased with increasing Co amount and A-site deficient perovskite is very effective on reducing reactivity. The (La0.8Sr0.2)xMn0.8Co0.2O3 (X=0.9-1) composition is not reactive with YSZ in experimental range. The electrode reaction reaction resistance increases due to reaction product.

  • This paper presents the analysis on the manipulability of a wheeled mobile manipulator which consists of a wheeled mobile platform and a manipulator atop. It is assumed that the mobile platform is a deficient system and the manipulator is a nonredundant system, but the mobile manipulators as a whole is a redundant system. First Yoshikawa´s definition of the manipulability ellipsoid for a redundant/nonredundant system is extended to a deficient system. Second, the effects of the nonholonomic constraint of the mobile platform and the location the mobile platform and the manipulator is analyzed.

  • The growth of solutions of second order complex differential equations f" + A(z)f' + B(z)f = 0 with transcendental entire coefficients is considered. Assuming that A(z) has a finite deficient value and that B(z) has either Fabry gaps or a multiply connected Fatou component, it follows that all solutions are of infinite order of growth.

  • It is well known that intaking alcohol chronically and heavily causes many formsof physical systemic distress including serious chronic alcoholic liver disease such as alcoholic hepatitis, fatty liver, liver cirrhosis and hepatoma. Carbohydrate-deficient transferrin (CDT) is known as a specific marker in detecting and monitoring alcohol associated disease. Weanalyzed various alcohol-associated parameters to evaluate the clinical usefulness of CDT. The first patient group consisted of fifty patients, who had been diagnosed with alcoholic liver disease from January 2003 to June 2004 at Chungnam National University Hospital. The second group consisted of 12 patients with non-alcoholic liver disease. The third group consisted of 19 teetotalerswho had visited the hospital for the purpose of routine healthcare checks. Various hepatic parameters such as CDT, $\small{\Gamma}$-GT (gamma-glutamyl transferase), AST (aspartate aminotransferase) and ALT (alanine aminotransferase) were compared in the three groups. CDT and AST increased in direct proportion to the amount and duration of alcohol consumption with high significance, but $\small{\Gamma}$-GT and ALT showed arbitrary patterns with no statistical significance. The sensitivities of CDT, $\small{\Gamma}$-GT, AST and ALT were 74 %, 96 %, 68 % and 58 %, respectively and the specificities were 95 %, 74 %, 68 % and 79 % in order respectively. The correlation study of CDT with $\small{\Gamma}$-GT, AST and ALT showed a very low value of correlation coefficients, implying that CDT could be taken as an independent parameter in evaluating alcohol liver disease compared to $\small{\Gamma}$-GT, AST and ALT. This present study suggested that CDT coud be one of the most useful parameters in reflecting the amount and duration of alcohol consumption as well as being another independent parameter in assessing and following up patients with alcoholic liver disease. Moreover we recommend it is the best method of measuring both CDT and $\small{\Gamma}$-GT in patients with alcoholic liver disease.

  • Calcium (Ca) is an essential element to maintain body homeostasis. However, many factors disturb calcium absorption. Aspartic acid chelated calcium (AAC) was synthesized by new methods using calcium carbonate and aspartic acid. This study was carried out to investigate the bioavailability of AAC in Ca-deficient rats. The experimental groups were as follows: NC; normal diet control group, CD-C; untreated control group of Ca-deficient (CD) rats, CD-$CaCO_3$; $CaCO_3$ treated group of CD rats, CD-AAC; AAC treated group of CD rats, and CD-SWC; and seaweed-derived Ca treated group of CD rats. The Ca content of various types of Ca was held constant at 32 mg/day, and the four CD groups were fed for 7 days after randomized grouping. Ca content in serum, urine, and feces within feeding periods were analyzed to confirm Ca absorption. Serum Ca content was significantly higher in the CD-AAC (11.24 mg/dL) and CD-SWC (10.12 mg/dL) groups than that in the CD-C (8.6 mg/dL) group 2 hours following the first administration. The Ca content in feces was significantly lower in the CD-AAC (35.4 mg/3 days) and CD-SWC (71.1 mg/3 day) groups than that in the CD-$CaCO_3$ (98.7 mg/3 days) group (p > 0.05). AAC had a 2.3-fold higher absorption rate of Ca than that of SWC. No differences in fibula length were observed in the NC and CD groups. The fibula weights of the CD-AAC (0.33 g) and CD-SWC (0.33 g) groups increased compared to those in the CD-C (0.27 g) group; however, no significant difference was observed between the CD groups. We conclude that bioavailability of AAC is higher than that of seaweed-derived Ca or inorganic Ca. Thus, these findings suggest the AAC has potential as a functional food material related to Ca metabolism.

  • Purpose: To analyze the dimensions of the embrasure space between the maxillary central incisors as potential factors influencing interdental papilla fill and height. Methods: The embrasure dimensions between the maxillary central incisors of 100 subjects (40 females/60 males) were assessed with clinical, study model, and radiographic examinations. Variables of the complete and deficient papilla fill groups were compared. Multiple regression analyses were performed to investigate potential influence of the distance between the contact point and bone crest (CP_BC), horizontal interdental distance (HID), and facio-lingual thickness (FLT) at the papilla base on complete/deficient papilla fill and papilla height (PH). Results: CP_BC was the only variable that showed a significant difference between the complete and deficient papilla groups (P<0.05). When the CP_BC was less than 5 mm, the embrasure spaces between the maxillary central incisors were completely filled with interdental papilla. Multiple regression analyses revealed that a significant predictor for complete/deficient papilla fill was CP_BC, and significant predictors for PH were CP_BC and HID (P<0.05). Conclusions: The chances of complete papilla fill increased as CP_BC decreased, while PH increased as CP_BC and HID increased. However, the FLT of the papilla base did not appear to affect papilla fill or PH. From an esthetic perspective, CP_BC as well as HID should be considered as factors influencing the topography of interdental papilla.
