A rigid-viscoplastic finite element code for superplastic forming processes has been developed The material is assumed to be isotropic and a modified Coulomb friction law is adopted to explain contact between tool and sheet. This code uses the triangular element based on the membrane approximation and a hierarchical contact searching method is implemented The optimum pressure-time relationships for target strain rate are calculated by several pressure control algorithms. By the analysis, optimum pressure-time curves and deformation behavior are predicted.

Consumer information influences purchasing behavior; however, less is known about the relationship in the credit market. Credit markets offer consumers a complex array of different products when choosing mortgages. The current study examines whether borrowers search for the very best terms when making major decisions about borrowing money or obtaining credit as well as explores the relation between consumer information seeking and the cost of credit. This study demonstrates the existence of price dispersion between those who made an extensive information seeking and those who did not. When controlling for the proxies of creditworthiness and demographics of the respondents, it is found that those who made a great deal of information seeking tend to have lower mortgage rates than those who made almost no information seeking. This study offers financial educators and policy makers suggestions on how to help consumers make better financial decisions.

When the parasitic wasp Microplitis croceipes experiences odors while feeding on sugar water, it learns to associate the odors with sugar and thereafter exhibits typical food searching behavior in response to the odors. Previous studies have shown that this wasp can be used for detection of the small amount of explosives or other volatile chemicals. In the present study, we examined if this wasp can learn and report narcotic odors. Males of M. croceipes were trained to link sugar water with pseudo-narcotic scents that have been used for training narcotic detection dogs, and their behavioral response to the trained odors was observed. The males that had been given either an odor or sugar water did not show any positive response to the odors. However, when the wasps were given a combination of sugar water and either the pseudo-Cocaine, Heroin, LSD or Marihuana, they quickly learned to associate the odors with sugar, and thereafter positively responded to those odors. Our results suggest that this wasp can be used for detection of these narcotics.

Objectives : This study investigated the health information such as the general health information, the health product information, and the hospital information, and we wanted to identify the association between internet health information and the health related behavior by analyzing the process after people search the Internet. Methods : A telephone survey with structured questionnaire was performed by trained surveyors. The respondents were sampled proportionate to the Korean demographic distribution with considering the city size and the populations' ages and gender. The survey was conducted from October 2006 to November 2006. Results : Out of 3,758 successfully connected persons of age 20 or more, 871(23.2%) respondents had used Internet health information during the last year. The purposes of searching the Internet for health was, 1) to get general health information (717 cases, 81.0%), 2) shopping for health product (109 cases, 12.3%) and 3) seeking information about hospital selection (59 cases, 6.7%). Our research showed that the process after searching the Internet for health information depends on the purpose of the search. 68.8% of the searchers for general health information, 67% of the searchers for health product shopping and 64.4% of the searchers seeking information to guide hospital selection were satisfied with their Internet search. However one third of the respondents reported not being satisfied with the result of the search. Conclusions : Unsatisfied consumers with internet health information tended to ask lay referrals from others or they gave up seeking health information. The health information system should be improved to increase the accessibility and to provide reliable and effective information. Also, a more user-centric community is needed in order to strengthen the effective role of lay referrals among the internet users.

Growth in online channels has created fierce competition; consequently, retailers have to invest an increasing amount of effort into attracting consumers. In this study, eye-tracking technology examined consumers' visual behavior to gain an understanding of information searching behavior in exploring product information for fashion products. Product attribute information was classified into two image-based elements (model image information and detail image information) and two text-based elements (basic text information, detail text information), after which consumers' visual behavior for each information element was analyzed. Furthermore, whether involvement affects consumers' information search behavior was investigated. The results demonstrated that model image information attracted visual attention the quickest, while detail text information and model image information received the most visual attention. Additionally, high-involvement consumers tended to pay more attention to detailed information while low-involvement consumers tended to pay more attention to image-based and basic information. This study is expected to help broaden the understanding of consumer behavior and provide implications for establishing strategies on how to efficiently organize product information for online fashion stores.
