Marketing information systems become a competitive weapon that supports firms in making decisions on the operation of marketing-related activities. However, little research regarding the operating strategy of marketing information systems has been conducted in Korea. Considering that this issue has been studied in the United States, this paper conducted a global benchmarking on the operating strategy of marketing information systems between Korean and the United States firms. The result of this global benchmarking suggests recommendations on supports from three management levels, the mix of 4P, the management of marketing, data from environment, and information sources.

We investigate global bifurcation in the motion of an harmonically excited circular plate with one-to-one internal resonance. A perturbation method developed by Kovacic and Wiggins is used. Silnikov type homoclinic orbit has been pursued but it has turned out not to exist.

The goal of the UN Framework Convention on Climate Change (UNFCCC) is to stabilize atmospheric CO2 concentration for preventing global warming in future. However, there are many unknown factors regarding stabilization of CO2 concentration. What level of concentration should be appropriate to prevent global warming？ When should we stop the increase of CO2 concentration\ulcorner What kind of countermeasures of reducing CO2 emission will be available for CO2 stabilization？(omitted)

This article studies a modified BFGS algorithm for solving smooth unconstrained strongly convex minimization problem. The modified BFGS method is based on the new quasi-Newton equation $B_k+1{^s}_k=yk\;where\;y_k^*=yk+A_ks_k\;and\;A_k$ is a matrix. Wei, Li and Qi [WLQ] have proven that the average performance of two of those algorithms is better than that of the classical one. In this paper, we prove the global convergence of these algorithms associated to a general line search rule.

For global electronic market, several market place standards are developing now. Though, a standard is different from others they are pursuing the same purpose of uniworld market. In this study, two standards(ebXML and UDDI) which are most strong enough to urge field engineers to consider the standards in making their products were focused. Additionally, the development priorities of ebXML which were viewed from field engineers were summarized. Finally, government actions required by field engineers to promote the development of global market place were summarized.

Contrast enhancement in the field of ultrasound imaging contributes to improve the accuracy of medical diagnosis by enhancing the visibility of ultrasound images. This paper proposes a contrast enhancement method that improves the contrast of ultrasound images both globally and locally by fusing global and adaptive contrast enhancement methods. Experimental results show that our approach yields more competitive results than the existing global and adaptive contrast enhancement methods in enhancing the visibility of ultrasound images.

It appears our global society and economy are here to stay, despite current events. Mass communications including The Internet, increased world travel, and more and more consumers developing the ability to afford consumer goods, are all helping to bring world cultures closer together. Indeed, the world is rapidly changing and the fashion consumer, is especially affected. Despite the increased commonalities of peoples of the world, culture is a concept crucial to the understanding of consumer behavior. Marketers must understand the values, ethics, an customs of societies around the world to be successful in the global marketplace.
