For a NAND booting based embedded system, an application program on the NAND flash memory is downloaded to the RAM when the system is booted. In this case, the application program exists in both the RAM and the NAND flash so the RAM usage is increased. In this paper, we suggested the demand paging technique for the decreasing of the RAM usage for OS-less NAND booting based embedded systems. As a result of a benchmark test, 40~80% of the code memory usage was reduced with below 5% of execution time delay.

The CISG entrusts many problems to trade or practice : for example the problems which can't be compromised between civil law system and common law system ; the problems in which the application of usage or practice in universal ; the problems of rapid change according to trade circumstance. The purpose of this paper is to confirm whether the CISG is accomodating the usage or practice in its Text, and to find which topic is most closely related to usage or practice in CISG. The Article 9 in the CISG is a provision of usages or practices applicable to contract. But the problems of the CISG in the accomodation of usages or practices are that it lacks the definitions of ‘usage’ and ‘practices’, the CISG is not concerned with the validity of any usage according to Article 4, and the application of usage or practice may differ in litigation and arbitration The topics such as delivery of goods, payment of price and the transfer of risk are most closely related to usages and practices. The delivery of goods and the transfer of risk are determined by the trade terms like FOB or CIF. But the method of identification and the risk for the sale of goods in transit can't be determined by the trade terms in INCOTERMS(1990). So the CISG may serve as complementing role. In payment of price, the trade term does not refer to the time and place of payment. So the CISG may be the basis of interpretation. Likewise the usages and practices such as trade terms, UCP and so on, can be expected to play a significant role in complementing and interpreting the CISG.

With the rapid growth of e-commerce, marketers are able to observe not only purchasing behavior on what and when customers purchased, but also the individual Web usage behavior that affect purchasing. The richness of this information has the potential to provide marketers with an in-depth understanding of customer. Using commonly available Web log data, this paper examines Web usage behaviors at the individual level. By decomposing the buying process into a pattern of visits and purchase conversion at each visit, we can better understand the relationship between Web usage behavior and purchase decision. This allows us to more accurately forecast a shopper's future purchase decision at the site and hence determine the value of individual customers to the siteAccording to our research, not only information seeking behavior but also visiting duration of a customer and participative behavior such as participation in event should be considered as important predicators of purchase decision of customer in a cosmetic internet shopping mall.

This paper introduces a sequential clustering technique as a tool for an effective grouping of transmission systems. The interconnected network system retains information about the location of each line. With this information, this paper aims to carry out initial clustering through the transmission usage rate, compare the similarity measures of regional information with the similarity measures of location price, and introduce the techniques of the clustering method. This transmission usage rate uses power flow based on congestion costs and similarity measurements using the FCM(Fuzzy C-Mean) algorithm. This paper also aims to prove the propriety of the proposed clustering method by comparing it with existing clustering methods that use the similarity measurement system. The proposed algorithm is demonstrated through the IEEE 39-bus RTS and Korea power system.

Many companies today use information systems to maintain competitive advantage and to give immediate responses to customer requests. Over time, however, many of these companies failed to make the most of such information systems because the users stopped utilizing the system. While many reasons offer explanations to the phenomenon, this study analyzes how usage intention of information system can be enhanced by changing the environment and usefulness of the system from the user's perspective. Active and wide-ranging researches using the Technology Acceptance Model (TAM) have been carried out on an individual's tendency to using new technology. But, many of the studies remain focused on improving user intention by enhancing the ease of use and usefulness of the system under PC applications or Enterprise applications. The personalized intranet system is not only bringing about sweeping changes to a company's information systems environment but also providing users with freedom to design their own working environment, personalization, to Corporate Information Systems (CIS). Results from empirical tests on intranet systems verify that through personalization, a more voluntary information system environment can be created and that by increasing the ease of use and usefulness of the system, users can become more favorable to accepting new technologies and ultimately result in improved usage intention. This study suggests personalization variables and model for implementing a voluntary CIS for information system developers.
