This study has two research objectives related to end-user computing (EUC). One of the research objectives was to investigate the current status of EUC of Korean firms. Another research objective was to examine the relationship between individual differences of end-users and EUC success. Using survey data from 752 end-users of 23 firms, the surrent status of EUC and the relationship between individual differences of end-users and EUC success were investigated. The current status of EUC was examined from six perspectives: 1). what is the characteristics of EUC strategy of Korean firms, 2). what are the individual characteristics of end-users in Korean Firms, #0. what are the characteristics of tasks performed by end-users using computer, 4). what are the application a areas of EUC, 5). How end-users are satisfied with the support of firms, 6). what are system usage and satisfaction of end-users. It was also foud that individual differences of end-users are related to EUC success. More specifically, it wat shown that the male gender, younger age, higher level of education, higher rank and organizational tenure, higher math ability, thinking type of cognitive style, positive and optimistic attitudes toward computer, more experience with computer, more computer education and knowledge are individual differences variables associated with EUC success. The results of stepwise regression analysis suggested that the individual difference variables accounted for 14%, 25%, 39% and 30% of the variances of four EUC success variables, satisfaction for outcome, satisfaction for ability, frequency of computer use, and the number of tasks, respectively. These empirical findings suggest that EUC managers should consider individual differences of end-users in managing EUC, such as education, training, support, and human resource management, to maximize potential benefits of EUC.

This Study is to Explain the Reason of Stagnation of Technological Innovation for Digitalized Products in Competitive Market by Using the Concept of Consumer's Technical Appreciation Ability and by Employing Evolutionary Game Theory. In this Study, Consumer's Behaviors are Divided into Two Areas (Areas I and II). In Area I, Both Firms and Consumers Instinctively Welcome the Technological Innovation of Digitalized Products so that their Technological Skills are Likely to Advance Rapidly in a Short Time. On the Other Hand, in Area II, Consumers Feel Uncomfortable in the Usage of Advanced Digitalized Products so that they are Likely to Choose Digitalized Products Under Optimized Technology Condition. In other Words, Consumers want to the Old Models with Already Optimized Technology Rather than a Bland New Model. This Situation Allows Managers to make a Bland New Model Similar to a Earlier Model in many ways. Therefore, the Innovation of Digitalized Products may be Stagnated.

The purpose of this study is to investigate if there is any regional distribution difference in the frequency of geographical location's name mentioned on the SAT Korean geography test. The reviewed items were used for geography subject test in Korean SAT exam in between 2005 and 2015. Researchers analyzed how often a location had been mentioned in the form of maps, captions, and graphs in the national college entrance exam for 11 years. The result indicated that 42% out of the 220 items were using map and about 33% of them represented a specific region. Especially, items related with climate, industries, and local area section contained a specific area information more frequently than others. Moreover, there were 76 cities mentioned in geography subject test on Korean SAT exam during 11 years and 25 places among them were referred to more than three times. The most frequently appeared city was Seoul followed by Incheon, Daegu, Busan, Gangneung, and Jeju and this result shows that there were some regional bias in geography test on the SAT Korean exam.

Consumption has generally become more fragmented, hedonic and individual specific, satisfying not only functional but also emotional needs. In parallel, customer satisfaction is now thought to be both a cognitive and affective response, and the closely related concept of job satisfaction is commonly seen as an emotional reaction. The reasoning within quality management does, however, still lean heavily toward cognitive judgements (i.e. performance ratings), the emotional component clearly being under explored. Further, performance variables have shown not to be significant in predicting satisfaction for certain 'experience products', the effect fully mediated by emotions. As a consequence a cognitive judgement based quality concept has lost its ability to predict satisfaction, which clearly contradicts with the modem quality definition, stressing quality as the ability to satisfy the customer. Emotions have however entered the quality discourse and it has been proposed that having customers that are merely feeling satisfied will not suffice. Instead, there has been a plethora of executive exhortations in the trade press calling on business to 'delight the customer'. Strategies for doing so have however usually been imprecise and unclear, and the different drivers of delight and satisfaction are not well explored. This paper aims to complement the previous cognitive dominance by exploring the multiple emotional responses involved in customer satisfaction. A conclusion being that we currently are measuring something, in terms of satisfied, that is more or less independent of what we aim for, in terms of delight. It is also most likely that - depending on the situation, product, and person - other positive and negative emotions are more important outcomes of purchase and usage than merely satisfaction. It is questioned whether a single, summary response such as satisfaction is feasible or even desirable.

In this study, we investigated the methods of using the Cabri3D program for education of problem solving in school mathematics. Cabri3D is the program that can represent 3-dimensional figures and explore these in dynamic method. By using this program, we can see mathematical relations in space or mathematical properties in 3-dimensional figures vidually. We conducted classroom activity exploring Cabri3D with 15 pre-service leachers in 2006. In this process, we collected practical examples that can assist four stages of problem solving. Through the analysis of these examples, we concluded that Cabri3D is useful instrument to enhance problem solving ability and suggested it's educational usage as follows. In the stage of understanding the problem, it can be used to serve visual understanding and intuitive belief on the meaning of the problem, mathematical relations or properties in 3-dimensional figures. In the stage of devising a plan, it can be used to extend students's 2-dimensional thinking to 3-dimensional thinking by analogy. In the stage of carrying out the plan, it can be used to help the process to lead deductive thinking. In the stage of looking back at the work, it can be used to assist the process applying present work's result or method to another problem, checking the work, new problem posing.

ITS industry has general characteristics of Information Economy such as network externality and information duplex. It also has characteristics exclusive to ITS including timing and locality of information, spontaneous monopolist ability, public use, and system integration. Due to its characteristics ITS industry demands different business strategies and industrial policies from past economy. Reflecting on network externality, it would be more effective to open and mutually share or build a strategic coalition among the competitors and share the market, standardization at early stage is necessary for the market maturation. Reflecting its coexistent characteristics of spontaneous monopolistic ability, public use and profitability in ITS industry it is desirable to make determination on supply source and financial funding source for each system after reviewing public usage and profitability. ITS industry characteristics in Information Economy and the effects of these characteristics on business strategy and industrial policy are analyzed in this research.

Using a strain-controlled rheometer, the steady shear flow properties of aqueous xanthan gum solutions of different concentrations were measured over a wide range of shear rates. In this article, both the shear rate and concentration dependencies of steady shear flow behavior are reported from the experimentally obtained data. The viscous behavior is quantitatively discussed using a well-known power law type flow equation with a special emphasis on its importance in industrial processing and actual usage. In addition, several inelastic-viscoplastic flow models including a yield stress parameter are employed to make a quantitative evaluation of the steady shear flow behavior, and then the applicability of these models is also examined in detail. Finally, the elastic nature is explained with a brief comment on its practical significance. Main results obtained from this study can be summarized as follows: (1) Concentrated xanthan gum solutions exhibit a finite magnitude of yield stress. This may come from the fact that a large number of hydrogen bonds in the helix structure result in a stable configuration that can show a resistance to flow. (2) Concentrated xanthan gum solutions show a marked non-Newtonian shear-thinning behavior which is well described by a power law flow equation and may be interpreted in terms of the conformational status of the polymer molecules under the influence of shear flow. This rheological feature enhances sensory qualities in food, pharmaceutical, and cosmetic products and guarantees a high degree of mix ability, pumpability, and pourability during their processing and/or actual use. (3) The Herschel-Bulkley, Mizrahi-Berk, and Heinz-Casson models are all applicable and have equivalent ability to describe the steady shear flow behavior of concentrated xanthan gum solutions, whereas both the Bingham and Casson models do not give a good applicability. (4) Concentrated xanthan gum solutions exhibit a quite important elastic flow behavior which acts as a significant factor for many industrial applications such as food, pharmaceutical, and cosmetic manufacturing processes.
