We extract the symptom of panic disorder from the context awareness environment. It extracts body context information through natural movement that exists in everyday life and uses a component of panic disorder. The ontology theory can be used to provide information on the degree of symptoms of panic disorder through inference process. For the components of panic disorder to the information processing based on ontology are defined as Classes. Panic disorder index is expressed through ontology modeling so that the condition of panic disorder can be known. The derivation of panic disorder component and panic disorder index will enable context awareness based information service for panic disorder. The context information is periodically synchronized with the context awareness on based device. Panic disorder can be used to improve the lifestyle of panic disorder.

This study aims to provide a customized dynamic kiosk screen that considers user characteristics to cope with changes caused by increased use of kiosks. In order to optimize the screen composition according to the characteristics of the digital vulnerable group such as the visually impaired, the elderly, children, and wheelchair users, etc., users are classified into nine categories based on real-time analysis of user characteristics (wheelchair use, visual impairment, age, etc.). The kiosk screen is dynamically adjusted according to the characteristics of the user to provide efficient services. This study shows that the system communication and operation were performed in the embedded environment, and the used object detection, gait recognition, and speech recognition technologies showed accuracy of 74%, 98.9%, and 96%, respectively. The proposed technology was verified for its effectiveness by implementing a prototype, and through this, this study showed the possibility of reducing the digital gap and providing user-friendly "barrier-free kiosk" services.

The switching system software is large scale, real-time multi-task system which requires high reliability. The reliability assessment of large-scale software is very important for the success of software development project. For this raeson, the software quality measurement is much more important. In this paper, we have learned about the software reliability, metho of the analysis of failure data and estimation of software quality. To estimate the software reliability, using the failure data found during of the system test. We apply the two software reliability growth models, named Goel-Okumoto(G-O) and S-shaped model, to estimate the software reliability. Also, we compared with the results and we reviewed fully not only development cycle but validation and verification of the test data, for each software versions. This paper presents a software reliability model that suitale the software development project and the activeity of quality control for the switching system.

In copyright dispute on software, appraisal procedure is needed, which is regarded as an implementation of the right to fast trial. Considering that, in practice, there has been a long discussion of attempting to operate the software appraisal as a summary procedure. This was done usually by reducing the resources devoted to the summary procedure, however, this way inevitably makes difference in a result obtained through the procedure. Therefore, this research reviewed the previous operation of summary procedure in software appraisal, focusing on intrinsic nature of the summary procedure and role of software appraisal in the trial process.

A new scheme needed to improve digital information accessibility with overall environment for handicapped persons is introduced in this paper. The improvement effects of digital information accessibility for handicapped persons are expected only when all the necessary hardwares and softwares need to input, process, output of information with social elements are provided all together. There are many previous papers regarded on web accessibility or IT technologies for handicapped persons separately. However, these subjects and computer accessibility are described here as a combined subject, and a new integrated improvement scheme including social factors and technical factors is suggested in this paper.

Most of information and communication assistance machinery and tools for disorder people of Occupied are machinery and tools for a visual impairment person and software, The things which can apply to only a specification disorder type and a specification disorder part are most, A special keyboard or a special mouse device of the handicapped person that disorder rank is comparatively the hardness makes the mainstream. It is reported in diffusion rate being very low if I compare this with total disorder population. I study new 1 plan which it can be applied to various disorder types and disorder parts through an intelligent special input device in a study of a book and, I designed this at the real standard that I could manufacture and incarnated it. In addition, I suggested this in a base for a design of a universal supporting input device and suggestion for the side of incarnation plan and a future study direction.

This study proposes design of courseware based on scaffolding for teaching math word problem solving of students with intellectual disabilities. This courseware not only offer various technological supports to solving difficult problems of students with intellectual disabilities but also systematically withdraw that supports. Compared with previous related softwares, this courseware has potential that can adapt math strategies to meet different needs of individuals with intellectual disabilities, increase independent learning ability of learners and maintain high level of motive through successful problem solving experience.
