This study is what tried to examine the importance of material in industrial design. Then, if planning is to start of product design, the use of material is the last step to complete design. Design material has existed from the time before mankind were born, and the new material which is useful for human beings is developing rapidly. It is no exaggeration to say that our environment is the aggregation of material which was surrounded with us. Then, material has the timely, spatial and cultural feature as well as physical feature. Besides, all sorts of functions of communicating information are being contained in accordance with the character of material. The outside surface of material has the function to develop the sense organ of human beings. This study examines 4 kinds of cultural features in design materials and shown by findings is as follows : Rrst is the technical progressivity to lead new Design form. Second is the symbolic nature to perform the communication function. Third is the sensible attribute to develop surface effect of Design material. Fourth is the future-oriented nature to convince the future such as new material and technology etc. Thus, so as to perform the competitive product design, it is important to grasp the harmony between material and design, structure and processing, and the substantial meaning that the material has and apply them properly, above all. Because the discovery of material will be the measure to forecast future design.

In response to the changing demands of ever competitive market, SK Telecom has built a new marketing system that can support dynamic marketing campaigns and, at the same time, scale up to the large volumes of data and transactions for the next decade. The system which employs Unix-based client-server (using Web browser interfaces) architecture will replace the current mainframe-based COIS system. The project, named NGM (Next Generation Marketing ), is unprecedentedly large in scale. However, both managerial and technical problems led the project into a crisis. The application framework that depended on a software solution from a major global vendor could not support the dynamic functionalities required for the new system. In March 2005, SK telecom declared the suspension of the NGM project. The second phase of the project started in May 2005 following a comprehensive replanning. It was decided that no single existing solution could cope with the complexity of the new system and hence the new system would be custom-built. As such. a number of technical challenges emerged. In this paper, we report on the three key dimensions of technical challenges - middleware and application framework, database architecture and tuning, and system performance. The processes and approaches, adopted in building NGM system, may be viewed as "best practices" in the telecom industry. The completed NGM system, now called "U.key System," successfully came into operation on the ninth of October, 2006. This new infrastructure is expected to give birth to a series of innovative, fruitful, and customer-oriented applications in the near future.

The concept of 'Picturing' is beyond the 'Illusion' of traditional art in the Digital Media era. It is a 'Suffering' of the 'Re-appearance' that is masquerade the 'Actual' as a 'Digital Apparition.' This study aims to concern the point of view on the above subject; the 'Picturing' through the analysis of communication problems in the digital era. To begin with, need to define the concept of 'Picturing' and how it is expected to have a role through the accessibility of medium use, intervention by body and images. Also, I suggest a new approach to 'Picturing' as a new mutual communication method. Body, Digital media, and Image. These three principles of 'Picturing' create huge benefits to our world/nature whether we want it or not. It seems to become more and more of powerful self-replicating organism. We have to be aware what sort of images are surrounding us and how transmitting it to where in/on our body via newest sophisticated media we use. 'Picturing' is an invasion of ordinary, no longer exists pleasure for body, no longer speaks intension of its next destination. It strongly self-grows and also controls us in the name of Digital media era. However, 'Picturing' is a mode of re-imaging activity and also suggestion of re-appearance practice.

Recently varieties of user groups are formed as the number of people using cyber chatting gets increased and there are many changes in the range and field of its use. But because most of the cyber chatting systems are being operated to enlarge the additional sonics use, the using environments are stereotyped. And as its function is being various as well, it can not provide with a user-centered environment. So this thesis compares and analyzes the problems derived from the usability evaluation for solving the problems in using cyber chatting systems, and presents the guidelines of emotion-intended user interface design for improving the usability as the result of the analysis. First, this study investigates cyber chatting systems as a means of web communication tools through the existing literatures. Secondly, this study finds out the problems in using them through satisfaction evaluation, heuristic evaluation, performance evaluation, and observation evaluation and presents a way of solving the provisional problems in using them as the analysis of the result of usability evaluation. And this was proceeded for the purpose of applying and activating the better usability evaluation of cyber chatting systems later. Through the usability evaluation, it is found out that the structuralization of chatting function, the screen visibility by the size and arrangement of the compositional elements of a screen, and the improvement and development of the proper metaphor use of images and functions by the communication environment are necessary.

This study presents strategic implications for enhancing the competitiveness of the comprehensive health examination center through the study of its impact on the switching barrier with medical service value and medical service satisfaction as parameters. In order to achieve the purpose of this study, a total of 324 questionnaires were analyzed for customers who received health examinations at the general examination center. Covariance structure analysis was performed to test hypotheses and causal relationships. The results showed that the physical environment had a significant effect on the medical service value and medical service satisfaction. The value of medical service also had a significant effect on medical service satisfaction. The value of medical service was found to affect the transition barrier, but the satisfaction of medical service did not affect the transition barrier. The implications of this study are that physical environment has a significant effect on medical service value and medical service satisfaction. Therefore, modern medical equipment should be equipped with the latest medical equipment to minimize accurate examination and misdiagnosis through modernization of medical examination center. In addition, since the value of medical service has a significant effect on the switching barrier, it is necessary to establish a plan to enhance the value of medical service. We need to promote sustainable customer retention and creation of new customers through differentiated screening items and cost advantages over competitors. In addition to check-up services, efforts should be made to enhance the value of services such as strengthening medical communication and medical complex cultural spaces, and at the same time, establish an organizational culture of customer-first examination centers through the placement of excellent personnel and continuous education.
