The Common Criteria (CC) philosophy is to provide assurance based upon an evaluation of the IT product or system that is to be trusted. Evaluation has been the traditional means of providing assurance. It is essential that not only the customer' srequirements for software functionality should be satisfied but also the security requirements imposed on the software development should be effectively analyzed and implemented in contributing to the security objectives of customer's requirements. Unless suitable requirements are established at the start of the software development process, the re suiting end product, however well engineered, may not meet the objectives of its anticipated consumers. By the security evaluation, customer can sure about the quality of the products or sys tems they will buy and operate. In this paper, we propose a selection guide for If products by show ing relationship between security engineering and security evaluation and make help user and customer select appropriate products or system.

This research explores early mover advantages and performance in the cyber market based on an empirical test. It also examines whether early mover strategic capabilities are able to adopt mutually cumulative relationship in the cyber market. Early movers such as eBay.com and Amazon.com seem to have been able to defy exclusive relationship between strategic capabilities. Compared with their followers such as uBid.com and buy.com, they have been able to adopt strong focus, differentiation, and cost leadership strategies. The purpose of this paper is to investigate the differences in strategic choices based on the strategic capabilities and performance of online firms between early movers and followers. The study reviews early mover advantages and disadvantages, and a strategic typology based on Porter's model, as well as strategic capabilities based on the sand cone model.

The cDNA of tobacco mosaic virus-pepper strain (TMV-P) coat protein (CP) genes were introduced into tobacco plants (Nicotiana tabacum cv. Samsun nn) using a binary Ti plasmid vector of Agrobacterium tumefaciens. these cDNAs introduced into tobacco plants were detected by polymerase chain reaction. Symptom development was distinctly suppressed in the transgenic plant introduced buy sense CP cDNA when the plant was inoculated with TMV-P, while in transgenic tobacco plants of antisense CP gene, symptom development was not suppressed as in non-transgenic plants. TMV-P concentration in the sense CP transgenic tobacco plant was decreased to 1/14 of the concentration in non-transgenic plants. Expression of the kanamycin resistance gene of these transgenic plants could be detected in the progeny.

Upon the basis at the end of March 2005, we have the 38.91 million cellular phone subscribers over the country and the total diffusion rate of the cellular phone is reached up to 76.1%. At this moment, it can be said the most people use it since the demand is still going on. Turning to the operation company, this is serviced by the SK Telecom, LG Telecom, and KTF, and there are at least 7 manufactures producing it including Samsung, LG, KTF ever, Motorola, SKY, Pantac and Curitel, Most users periodically change the service vendor to the others for buying new model or changing the service vendor. It is understood the customer's action occurred by the differences of the brand cognition. In this study, along with some parameters including the difference of the vendor's brand cognition, difference of satisfaction (mobile telecommunication, product), and the possibility to buy the product again, I am going to find out the relationship between the satisfaction of the provider's service

The existing CSP systems is inefficient and brings about waste of budget in some operating aspects which show accumulation of unnecessary items, omitted or running short items and limitation of timely use of them. The purpose of this study is to analyze the actual situation of existing CSP(calculation and estimation of CSP requirements), and to suggest a few methods (post control system by activating buy-back system, and middle and long term operating system itself in relation to budget) to improve the CSP operating systems in order to maximize the effectiveness of combat strength and to contribute to the economic efficiency of defense management. The results show that improved method is efficient and effective by comparing with some actual data.

Recently, many companies and consumers are using Internet to sell and buy goods and manage their businesses. And for most companies, they have Electronic Commerce system and Enterprise Resource Planning (ERP) system. But the two systems manage separately and the data are not integrative. So it is hard to mangement the system alike and the costs may be higher than the system which has intergrated information. ebXML-based Electronic Catalog (e-Catalog) can provide intergrated information. In this paper, we took a manufacturing industry company for example. We planned to construct the e-Catalog System, analyze the products of the company as well as design e-Catalog system using ebXML to connect EC with ERPs.

This study investigates the wealth effect of foreign acquisition of U.S. based firms. Contrary to previous studies, this analysis demonstrates that after appropriate control of domestic-acquired targets, the wealth gains to the shareholders of targets in foreign takeovers are similar to those in domestic takeovers. This paper investigates the validity of the competitive acquisition market in cross-border takeovers and concludes that : 1) in cases of inward foreign direct investment into the U.S., foreign firms do not realize significant net benefits from acquisitions; and 2) the foreign acquirer is as well informed as its U.S, counterparts about the target's market. The results of this study are consistent with the view that each country has different motivations for investing in the U.S. market. Consider, for example, Japan. The evidence suggests that Japanese companies pay a considerable price for U.S. targets which have performed poorly before the takeover. While there is no specific rationale to explain why Japanese firms buy the most volatile and worst performing firms, international barriers may provide a possible reason for these anomalies. Overall, the evidence of this paper supports the view that foreign takeovers occur in a competitive acquisition market.
