Composite bipolar plates offer several advantages of low cost, light weight, and ease of manufacturing compared to traditional graphite plate. However, it is difficult to achieve both high electrical conductivity and high flexural strength. In this study, the hybrid carbons filled epoxy composite bipolar plates were fabricated to test electrical conductivity and flexural properties. Graphite powders were used as the main conducting filler and continuous carbon fiber fabrics were inserted to improve the mechanical properties of the composite. This hybrid composite showed improved in-plane electrical conductivity and flexural property. The moldability of the hybrid composite was also improved comparing to the continuous prepreg composite. This study suggested that the continuous carbon fiber inserted graphite/epoxy composites can be a potential candidate material to overcome the disadvantages of conventional graphite composite or continuous prepreg composite bipolar plates.

Combination effects of various beta-lactam antibiotics with vancomycin against methicillinresistant Staphylococcus aureus (MRSA) which were detected as hetero-vancomycin resistant Staphylococcus aureus (hetero-VRSA) by Mu 3-medium method, were evaluated. 24 MRSA strains of 22 inpatients, isolated in Dankook University Hospital from July-November 1998, were subjected to the study. MICs of antibiotics, alone or in combination, were tested with the agar dilution method. And fractional inhibitory concentration index (FIC index) were calculated to estimate the combination effect. πle average FIC index of imipenem, cepha10thin, flomoxef, cefpirome, arbekacin in combination with vancomycin was 0.608, 0.682, 0.743, 0.811, 0.840 respectively. So that we concluded that in most cases, beta-lactam antibiotic with vancomycin show relatively effective against hetero-VRSA, considering that their avearage FIC index was close to 0.5. We thought that the combination of vancomycin with imipenem is useful and recommendable choice of therapy in MRSA infection.

Recently, Internet Protocol TV technology has a latent power for searching information by using internet-connected interactive TV media. It is hard to browse and search web site conveniently since the visual and input devices are not sufficient for navigating through the websites. Zoomable user interface is a possible solution that may reduce users' task load and improve their performance. In this paper, we made three types of web browsers as scroll, physical zooming and semantic zooming type. Fifteen participants asked to do searching tasks and their task time, accuracy and subjective responses are recorded. In the result, though scroll type is evaluated more efficient than other types in task time and accuracy since participants are familiar with scroll type interface, semantic zooming type is highly rated in subjective responses such as perceived searching efficiency, satisfaction and joyfulness. This result implied semantic zooming is a possible solution which is improving user experience of searching websites using Internet Protocol TV.
