With the diffusion of Universal Design, interest in low-floor bus for the mobility handicapped person is increasing. In this study, we observed behavior patterns of passengers who are using low-floor bus based on video observation method. We investigated behavior patterns of passengers in Context of Use perspective. The components used in this Context of Use analysis were derived in consideration of various passengers, situations, and equipment. Drawing on these components, total 16 user behavior patterns are induced. The analysis of the usage case in correspondence with each behavior pattern showed that passengers demand more supportable equipment and individual behavior convenience including setting their personal belongings. We expect that the result of this study enables to understand major discussions of existing low-floor bus and to provide direction for designing next-generation city bus.

In order to research the effects of Shipjundaebotang(SDT) and Orostachys Herba(OH) on anti-tumor and immune response, the author performed this experimental study. Experimental groups are divided into five groups, which are solid extract of Orostachys Herba by water(OHW), solid extract of Orostachys Herba by ethanol(OHE), solid extract of Shipjundaebotang (SDT), solid extract of Shipjundaebotang added by solid extract of Orostachys Herba by water(SDT+OHW) and solid extract of Shipjundaebotang added by solid extract of Orostachys Herba by ethanol (SDT+OHE). In these experimental studies, extension of survival days for anti-tumor effect was observed, and de layed type hypersensitivity and rosette forming cell for cell-mediated immune response, hemagglutinin titers and hemolysin titers for humeral immune response, spleenic natural killer cell activity and carbon clearance (K-index) in vitro were measured with mice. The result were summerized as follows: I. SDT, SDT+OHW and SDT+OHE treated groups were significantly recognized to extend the survival days of tumor bearing mice as compared with the control group. 2. Delayed type hypersensitivity was significantly increased in SDT, SDT+OHW and SDT+OHE treated groups as compared with control group. 3. Hemagglutinin titer was increasred in all sample groups as compared with control group, but not significantly. 4. Hemolysin titers was significantly increased in SDT, SDT+OHW and SDT+OHE treated groups as compared with control group, and SDT+OHE treated group showed the increasing effect with significance as compared with the other sample groups. 5. For the effect of roselle forming cell quantitation, SDT, SDT+OHW and SDT+OHE treated groups showed the increasing effect with significance as compared with control group. 6. Natural killer cell activity was significantly increased in SDT+OHW as compared with comrol group, but the other groups, except OHW and SDT+OHW treated groups, revealed the increasing effect as compared with control group, but the significance was not admitted. 7. For the effect of K-index(Carbon clearance), SDT, SDT+OHW and SDT+OHE treated groups showed the increas ing effect with significance as compared with control group. 8. The study didn't show that Orostachys herba had any significance with survival days, anti-tumor effect and immune re sponse.

In this study, we proposed the most efficient driving posture based on the analysis of quantitative muscular strength and fatigue degree according to posture. Since driving include complicated actions required by a variety of ability and cause by extremes concentration or strain, drivers tend to feel tired easily. However, drivers cant recognize the fatigue degree by themselves. Moreover, the method for measuring the quantitative fatigue degree exactly is quite difficult to be secured. 9 professional bus drivers were participated. We analyzed the quantitative legs muscular strength when operating each pedal. And then we also analyzed the muscular strength and muscular fatigue degree according to driving pattern during bus driving. Therefore, we suggested the most efficient driving posture.
