Recently, the number of Internet shopping malls increases dramatically Internet shopping malls offer direct sales by electronic catalogs. As compared with to physical stores and paper catalogs, electronic catalogs differ in terms of the varieties and types of products offered, promotional efforts, service, interface, ordering and delivering, and so on. This paper analysed the features of electronic catalogs for fisheries by 45 variables. By descriptive statistics of electronic catalogs for fisheries, most electron)c catalogs had sufficient product related information. But promotion and transaction security related features were scarce. And some development technologies of electronic catalogs for fisheries were obsolete. By factor analysis, there were 9 factors of electronic catalogs for fisheries, that was, design of product pages, transaction information, playfulness, convenience of product selection, interface design, design of homepages, product information, learning capability, other electronic catalog related factor. Thus in standardizing electronic catalog for fisheries products, the above 9 factors should be reflected significantly.

The test technique for the failure caused by interaction between the customized interface and core function is necessary. We propose a component customization test technique by using the fault injection technique and the mutation test case selection technique. Our technique injects fault into where the customization failure may take place and selects the test case that differentiates the fault-injected component from the customized-component. Therefore, our test case has a good fault-detectability and can reduce the testing time by injecting a fault only into a place where the customization failure may take place in the interface.

In VEs (virtual environments) such as a CAVE system, there are three important operations : executive command decision, object selection and 3-D (three-dimensional) pointing. It is necessary to implement these operations in VEs intuitively and accessibly. In CAVE, it is possible for examines to walk and change their viewpoints freely. Then, the input devices which have excellent portability and rich expression are desired. Speech input satisfies both requirements. It is, however, very difficult for the speech input to indicate an exact point in 3-D space. Therefore, an extendable virtual stick is employed and it supports speech input. This paper proposes a user friendly interface using speech and a virtual stick in CAVE system. In this paper, several applications appropriate for the proposed interface are developed. Some problems are pointed out from the applications.

This study discussed extensively the CD-ROM evaluation criteria that are necessary for library and information center to acquire the CD-ROM products. The evaluation criteria discussed in previous studies are divided into managerial and technical aspects, and especially the search software and user interface catagories in the technical aspect are investigated separately. Finally the basic checklist is suggested for the evaluation of CD-ROM product in appendix.

In order to provide the convenient access to the mobile services and the efficient utilization of the mobile devices, it is required to devise an intelligent user interface which guarantees the efficient task selection and transition in the limited input/output environments of the mobile devices. In this paper, we propose user task prediction models which are essential for the intelligent user interface, and an accuracy estimation model is also proposed for evaluating the prediction models.

Recently companies are aggressively Pushing ahead with integrating the systematical applications of internal and external information systems such as Data level, Application level, Process level in the company, Process level between companies. The EAI solution is generally considered as the necessary tool to integrate companies, but the appraisal standard for the EAI solution has not Vet settled in Korea, so the companies have difficulty in deciding whether to adopt the EAI solution or not. Through this report, we first introduce the KRA Project as the best practice in making an application of the settled standard to evaluate and adopt the EAI solution, and then suggest that it can be adapted to companies considering applying to the EAI solution.

Image morphing deals with the metamorphosis of one image into another. The field morphing depends on the manual work for most of the process, where a user has to designate the control lines. It takes time and requires skills to have fine quality results. It is an object of this paper to propose a method capable of realizing the semi-automation of field morphing using adaptive vertex correspondence based on image segmentation. The adaptive vertex correspondence process efficiently generates a pair of control lines by adaptively selecting reference partial contours based on the number of vertices that are included in the partial contour of the source morphing object and in the partial contour of the destination morphing object, in the pair of the partial contour designated by external control points through user input. The proposed method generates visually fluid morphs and warps with an easy-to-use interface. According to the proposed method, a user can shorten the time to set control lines and even an unskilled user can obtain natural morphing results as he or she designates a small number of external control points.

It has been studying actively that the process and the methodology for the safety security of the system suggested from international standards and domestic/abroad materials in Korea. However, these process & methodology can generate a lot of errors and deficiencies because the system is applied without considering the system characteristics and its scope (such as hardware, software, interface, etc.). Therefore, the type is defined as the safety process with the basis on general development process in this study, the potential hazards of the mock-up system which is developed are extracted thorough selecting a technique according to each type. In addition to it, the effect is compared and analyzed with various technique selection by each phase of the development process.

To comply to demand for a development requirement of aircraft design part, the expert system builds up standard knowledge-base based on presently maintained expert knowledge and experience in aircraft structure material selection. It also builds up database based on aircraft design open data, and standard calculation module used for present design and analysis method. This system is developed using Visual Basic language. The expert system standardize aircraft structure material selection and can be applied to all type of elementary stage of aircraft structure design. It is working on Windows, which has a friendly interface and is convenient for debugging, maintenance and transplanting. Explanation of the structure and the function of the system was given in this paper.
