The purpose of this study was to delve into the features of paradigm in conjunction with changing convergence culture in the 21st century's knowledge-based society, the influence of convergence paradigm on fashion, and changes in convergence culture. After identifying the features of the paradigm of knowledge-based society in association with changing convergence culture, the characteristics of fashion paradigm were examined in con=junction with the characteristics of the paradigm, and the convergence phenomena of modern fashion were investigated to figure out fashion trends. The findings of the study were as follows: According to the features of ubiquitous technology based on the theories of Mark Weiser and other futurologists, the characteristics of changing convergence culture in knowledge-based society could be classified into invisibility, relationship and materialized virtuality. When relevant theories were reviewed, invisibility, relationship and materialized virtuality are identified as the unique features of the paradigm of changing convergence culture in knowledge-based society. But those characteristics aren't separate concepts. Instead, they are being connected and fused together, thanks to universalized digital technology and ubiquitous technology. Changing convergence culture has brought a change to fashion paradigm as well. There is a type of design that lets all the characteristics stand out, and another design fuses just some of them together conceptually or formally. That is, fashion paradigm is marked by a combination of invisibility, relationship and an embodiment of virtual reality to be in line with changes in convergence culture.

The $L^1$-convergence of Fourier series problems through additional assumptions for Fourier coefficients were presented by W. H. Young in 1913. We say that they are the classical results. Using modified trigonometric series is the convenience method to study the $L^1$-convergence of Fourier series problems. they are called the neoclassical results. This study concerns with the $L^1$-convergence of Fourier series. We introduce the classical and neoclassical results of $L^1$-convergence sequentially. In particular, we investigate $L^1$-convergence results focused on the results of Bhatia's studies. In conclusion, we present the research minor lineage of Bhatia's studies and compare the classes of $L^1$-convergence mutually.

In order to solve the complicated problems faced by the spread of diversified information devices and changes in the user environment in recent years, the importance of training creative talent as well as the need for interdisciplinary convergent approach have emerged. As a future technology development project, convergence education with the design sector for training creative talent in the IT field is also urgent. In this study, we recognized the importance and problems of the convergent approach between IT and design sector by examining the convergence theory and cases with a focus on effective creativity development and sought a new direction for convergence education in the future by investigating the awareness on the convergent approach of college students and analyzing the results. This will be able to have significance as a basic study for discovering creative and innovative convergent talent in the IT and design sector in the future and strengthening basic competence.

Purpose - Mobile devices, especially mobile terminals capable of telecommunication and wireless connectivity, are leading the advancements in consumer electronics. Digital convergence drives the functions of various devices, such as cellular phones, MP3 players, personal digital assistants, and gaming, into a single device. This trend would continue and applications such as digital audio and video streaming (including personalized content delivery mechanisms) would soon be on a handheld device. As customers want mobile convergence devices, manufacturers are driving new initiatives in the emerging mobile device market. Given the roles played by device design and service content in user satisfaction of a mobile convergence device, this study focuses on identifying and measuring the constructs for the process by which user satisfaction is achieved. This study synthesizes the expectation-disconfirmation paradigm with empirical theories in user satisfaction. Device and service levels are separated, and nine key constructs for user satisfaction of mobile convergence devices are proposed. Insight into this process could help web-based businesses to improve user satisfaction, thus enhancing the effectiveness of e-commerce for sellers and buyers. Research design, data, methodology - This study draws on three users of mobile convergence devices as examples. To test there search model and hypotheses, survey questionnaires were sent to 607 mobile device users. Mobile device users were initially identified from several members, and subjects were randomly drawn. Data from 577 survey responses were finally analyzed. The unit of measurement and analysis in this research study is at a personal level. Results - The measurements for the constructs were developed and tested in a two-phase study. In the first phase, the device and service dimensions were identified, and instruments for measuring them were developed and tested. In the second phase, using the salient dimensions of the device and service as the formulating first-order factors, instruments were developed and empirically tested to measure satisfaction of the device and service. In measuring satisfaction of mobile convergence devices, the critical tasks are to identify the key constructs of such user satisfaction and to develop validated instruments to measure them. Hence, the results of this study have immediate implications for businesses and for research in user satisfaction of mobile convergence devices. Conclusions - This study provides reliable instruments for operationalizing key constructs in the analysis of user satisfaction of mobile convergence devices within the expectation-disconfirmation paradigm. Hence, convergence device makers will be able to examine whether their websites meet their customers' expectations by examining the device aspect of the mobile convergence device customers, and the service aspect expectations and disconfirmation. Moreover, the introduction of expectation and disconfirmation constructs brings the marketing aspect of convergence devices into focus for such retailers, an aspect crucial to the effective design of websites for online businesses. In addition,this study provides the metrics required to initiate future studies on user satisfaction of mobile convergence devices.

In this work, we generalize a family of optimal eighth order weighted-Newton methods to Banach spaces and study its local convergence to approximate a locally-unique solution of a system of nonlinear equations. The convergence in this study is shown under hypotheses only on the first derivative. Our analysis avoids the usual Taylor expansions requiring higher order derivatives but uses generalized Lipschitz-type conditions only on the first derivative. Moreover, our new approach provides computable radius of convergence as well as error bounds on the distances involved and estimates on the uniqueness of the solution based on some functions appearing in these generalized conditions. Such estimates are not provided in the approaches using Taylor expansions of higher order derivatives which may not exist or may be very expensive or impossible to compute. The convergence order is computed using computational order of convergence or approximate computational order of convergence which do not require usage of higher derivatives. This technique can be applied to any iterative method using Taylor expansions involving high order derivatives. The study of the local convergence based on Lipschitz constants is important because it provides the degree of difficulty for choosing initial points. In this sense the applicability of the method is expanded. Finally, numerical examples are provided to verify the theoretical results and to show the convergence behavior.

This study aims to investigate industry needs for convergence education in the field of nano-technology, bio-technology, robot, and design. Firstly, the area of convergence technology in nano-tech, bio-tech, robot, and design fields was examined through the literature review and case study. The areas were validated by the experts review who consisted of four industry experts and four professors in the relevant fields. Second, a questionnaire was developed for investigating industry's needs on convergence education. The questionnaire consisted of three parts: 1) awareness of necessity for convergence education, 2) the needs for convergence new technology education from the perspective of industry, and 3) opinions on convergence education. The questionnaire was validated by three engineering education experts. Third, the survey was conducted in cooperation with the Sector Council of Industrial Resources. A total of 400 respondents responded to the questionnaires: 98 in the nano-technology field, 74 in the design field, 58 in the robotics field, and 170 in the bio-technology field. Fourth the industry needs for convergence education were analyzed and implications were suggested. The results of this study are expected to provide a guideline for developing convergence education programs in higher education.

The IT convergence industry is expected to create some high added-value, yet the IT convergence service is still in its introductory stage, which requires the utilization of yet to be tried future technologies and development methodologies that have been never tried in the past; therefore, there is certain risk involved regarding the success of development during the introduction of service and the development of technology. From such perspective, this study found examples of the services in the IT convergence industries and the application technologies for the realization of those services; and conducted a research based on the examples, using the technical Characteristics classification; and based on the result, analyzed the standards and the peculiarity of technologies employed for the IT convergence service and the correlation and the complementarity between them; also identified the standards and the peculiarity of technologies required by the IT convergence services and analyzed the correlation between them; and finally analyzed the compatibility between the IT convergence services and the applied technologies. The conclusion of this study is expected to be utilized for selecting technologies for the introduction and the operation of the optimal IT convergence service and as a benchmark as well.

This study analyses on the history of uniform convergence, and discusses its educational implications. First, this study inspects 'overflowing of the Euclidean methodology' which was suggested by Lakatos as a cause of tardy appearance of uniform convergence, and reinterprets that cause in the perspective of 'symbolization'. Second, this study looks into the emergence of uniform convergence of Seidel and Weierstrass in this viewpoint of symbolization. As a result, of analysis, we come to know that the definition of uniform convergence had been changed into the theory of 'domain and graph' from that of 'point and function value' by the location change of the quantifier. As these results, this study puts forward an educational suggestion from an angle of epistemological obstacle, concept definition and concept image.

This study examined the impact of variables(collaboration, convergence motive, convergence thinking) on the creativity problem solving of engineering college students. 522 students among engineering colleges in Pusan and Ulsan were sampled. For the statistical analysis, analysis of covariance structure by AMOS 18.0 was applied. Results from structural equation modeling analyses indicated that a hypothesized model produced a better fit to the data than a comparative structural model. The hypothesized model shows the following results. On the basis of the hypothesized model, collaboration effected to directly convergence motive and creative problem solving, and convergence motive effected to directly convergence thinking, convergence motive effected to directly creative problem solving, convergence thinking effected to directly creative problem solving, and collaboration effected to indirectly convergence thinking by convergence motive. Therefore this study suggested the collaboration, convergence motive and convergence thinking are significantly variables to facilitate the creative problem solving for knowledge fusion in engineering.
