Organizations have attempted to develop Knowledge Management Systems for achieving competitive advantage by effectively managing organizational knowledge. However, if Knowledge Management Systems are not user-oriented, organizations may not attain desired goals. That is, it must be utilized and accepted by organizational members to be successful systems. This study proposes an extended Technology Acceptance Model and empirically validates it. For that purpose, a research model is set UP that consists of antecedent variables, perception moderators, and intention to use the system. Empirical data analysis found significant relationships among research variables, as suggested in research hypotheses. The results of the analysis indicated that perceived usefulness, ease of use, job relevance and information quality should be considered as important factors in designing Knowledge Management Systems. In addition, perceived value, incentive, affect, self-efficacy, and image were found to influence the perception of users in the usage situation.

The Architects' design process is subjective and mysterious'. If we can reveal this process, it will be very helpful to proceed similar design projects. In the aspect of steel production, Korea is a strong country, but in the aspect of steel usage, Korea does not show its impacts as compared with other countries'. Even though steel has many merits in design as well as in structure, in Korea we have not applied it as design elements. In this situation, the demand of steel in school buildings is increasing, but steel also is used only on the basis of the structural and material meaning. So this thesis tries to find design elements of steel structure buildings, which can be applied in school buildings, through the analysis of existing steel structure buildings and the characteristics of steel.

Universal Serial Bus (USB) is one of the most popular communication interfaces. When USB is used in more extended range, especially configuring home network by connecting multiple digital devices each other, USB interface uses the bandwidth in the way of Time Division Multiplexing (TDM) so that the bottleneck of bus bandwidth can be brought under the heavy traffic. In this paper, the more effective usage of bus bandwidth to overcome this situation is introduced. Basically, in order to realize the system for transferring real-time moving picture data among digital information devices, we analyze USB transfer types and descriptors and introduce the method to enhance the detailed performance of isochronous transfer that is one of USB transfer types.

Lately the usage of multimedia equipment with small LCD displays is rapidly increasing. Although many people use devices like cell phone and PDA, videos intended for TV or HDTV are sent to these mobile devices. Therefore, situation where it is hard for the user to view the desired scenes are growing more frequent. Currently, most services simply reduce the size of the content to fit the screen when they offer it for mobile devices. However, especially with sports broadcasts, there are many areas that cannot be seen very well because it was simply reduced in size. We are suggesting new motion how to let the user choose an area of interest based on Cognitive lattice. And present then sending it to the user in a way based on Focus Of Choice that fits the device.

This study investigated the current situation regarding college environments and the use of disposable goods, to inquire the environmental consciousness of college student consumers, and to identify factors that affect their use of disposable products. The major findings of this study are summarized in the following. First, college students' usage of disposable products was measured in two ways: the tendency to use disposable product and the quantities of disposable products consumed. The tendency to use disposable product was found to be 2.80/5, which indicates that college students' behavior of consuming disposable goods was less than moderate. On average, a college student consumed a total of 35 disposable products per month. Second, variables that affect college students' consumption of disposable products were investigated. The students who showed a higher tendency to use disposable products were those with more spending money, those without any experiences in the environmental organizations and clubs, those who had a low personal opinion toward university policies, those who regarded environmental protection as more important than economic growth, and those who thought environmental protection to be more important than fashion.

Collaborative filtering is one of popular techniques for personalized recommendation in e-commerce sites. An advantage of collaborative filtering is that the technique can work with sparse evaluation data to predict preference scores of new alternative contents or advertisements. There is, however, no in-depth study about the sparsity effect of customer's evaluation data to the performance of recommendation. In this study, we investigate the sparsity effect and hybrid usages of customers' evaluation data and purchase data using an experiment result. The result of the analysis shows that the performance of recommendation decreases monotonically as the sparsity increases, and also the hybrid usage of two different types of data; customers' evaluation data and purchase data helps to increase the performance of recommendation in sparsity situation.

Reliability growth modeling can be a requirement when bidding on large military hardware systems. Under current reliability warranty legislature, the reliability growth model can be later translated into necessary reliability performance which must be demonstrated over an extended period of usage. In this paper the modeling situation is concerned with determining the number of spares needed to support a projected reliability growth both at the fightine and in a depot inventory. The model differs from existing models for logistics planning in that we allow for the phenomena of reliability growth. The model can also be used to determine central depot staffing requirements based upon a specified system utilization.
