  • In the catalogs that have presently been under research, the product information cannot be represented in a classified form but it also fails to be well defined, lacking the description of detail information for various products on a systematic fashion. And the product information is duplicated on its representation. In this study, an implementing model is to be proposed to analyze and classify the information that can be in use of describing various products, and to describe an integrated products information for various types of products while making up for the weak points of presently available researches. Also, this study shows that it is possible for the proposed model to represent various units of product information with presently proposed model applied to computers and book products in high demand of transaction, and by implementing electronic catalogues in the existing researches to prove its efficiency.

  • Electronic products can be subjected to many different forms of shock. These shocks are usually experienced during transporting the electronic products from a manufacturer to customers. Drop tests are performed to test the product fragility before shipment. Package cushioning materials are often used to protect electronic products from severs shock environments. In the present paper, an algorithm to predict the shock responses of the main mechanical parts is developed by use of the shock analysis in which the modal parameters extracted from vibration test are used. These results are in good agreement with the results of drop test. By use of the shock response prediction algorithm developed herein, it is possible to predict the results of drop test at various drop directions and also to select the optimal package cushioning materials.

  • Modern vehicle has a lot of ECU(Electronic Control Unit) products to control many parts such as engine, transmission, brake, body and so on. ECU quality is one of important factors related to vehicle quality and driver's safety. Based on Bath-tub curve which presents failure rate during product lifetime, we designed and applied Accelerated Run-in Test into manufacturing line by simulating stress amount to ECU and developing the required software and efficient test equipment for mass production. This test makes ECU products stressed through electrical and thermal stresses under excessive driving condition, which induce potential initial failure of components in the ECU during production. The outcome until these days proved that Acceleration Run-in Test have reduced initial failure rates and increased quality of ECU products in the field outstandingly.

  • This research aims to examine consumers' general types of information search and their unsatisfactory factors in purchasing agricultural products on electronic commerce and analyze consumers' behavioral characteristics. As study subjects, 802 consumers who have visited the home pages of 14 households or companies, whose home pages are actively managed, were sampled. As a research tool, pop-up post and e-mail were used as research tools and questionnaires were asked three times. The date on research result were analyzed using SPSS 13 statistics package in terms of frequency, percentage, descriptive statistics, one-way ANOVA and correlation analysis.

  • Although the concept of usability has been well defined in the software usability engineering area, it is not appropriate to apply the same concept directly to the consumer electronic products. A new concept of usability appropriate for evaluating consumer electronic consumer electronic products was suggested in this study. It is characterized by integrating both the performance and the impression factors. Based on the concept developed, a systematic and integrated methodology for usability evaluation was proposed. The methodology contains four major steps; the development of the measurement methods for evaluating usability attributes, the development of the analysis techniques for the human interface elements, the development of the evaluation method for the usability of human interface elements, and the development of the usability model. The results of this study can be applied to evaluate the usability of various electonic products in a systematic and efficent manner.

  • Classivication scheme of usability element for the evaluation of consumer electronic product was developed in this study. Using hierachical structuring and clustering methods, usability element of consumer products interface is developed both for the performance perspective and for the image/appeal perspective of a product. Perfoormance element included variables such as simplicity, directness, learn- ability, flexibility, user support and effectiveness. Image/Appeal element included variables such as sensibility, descriptive impression, evaluation of appeal, and attitude towards the product. The classifi- cation scheme developed in this study is found to be comprehensive and robust relative to other existing paradigms. They can be effectively used and applied for the usability evaluation of consumer electronic products.

  • This paper suggests a data modeling scheme of human interface elements and their properties for consumer electronic products. The human interface elements were classified into three categories: individual, interaction and integration interface. The representative properties of each interface element were identified, and modeled by using the object-oriented technique. The results of this study are expected to be used for expressing the user interface of consumer electronic products. They are also expected to help understand the relationship between the usability and the user interface elements of a product.

  • In the era of the 4th industrial revolution, interest in flexible devices is increasing for information and communication technology electronic products. This is a hot technology field in which competition is intensifying to preoccupy the global market for flexible electronic devices because of the many advantages of ultra-lightweight, flexibility, design diversity, high applicability, and low cost. Some flexible electronic products have been commercialized in Korea, but they are still inadequate in terms of price versus performance, so technology development is required continuously. Particularly, the development of flexible electronic materials is emerging as a key factor for flexible electronic device applications. In this study, we will look into the flexible electronic material technology and industry trends following the trend of flexible technology changes in the display, secondary battery, and solar cell, which has emerged as national core industry and has secured global competitiveness. In addition, I want to introduce the Flexible Electronic Material Center, which was established to foster the flexible electronic material industry.

  • XML(eXtensible Markup Language) based electronic catalog is very useful for searching target information because of its structural and contents based searching support capability. And XML document editing is easier than HTML because of XML document is divided by structure, contents and presentation. This paper is to present a prototype of XML based Electronic Catalog Management System(ECMS) whose system consists of data input, output and manipulation system for inserting, updating, editing and deletion. A proposed system could resolved the problems at virtual intermediary shopping mall invloved in the difficulty of interoperability when customer try to compare similar products at mixed shopping mall and reduced web service costs at independent shopping mall by using XML format. The proposed ECMS offers rapid response capability for product data change of electronic catalog and easy and friendly interoperability among similar products.
