This study proposed a framework to clarify a viewpoint of quality problems, and to consider reliance, of context information in ubiquitous computing environments. The framework is structured as a sequence of steps in measuring the quality of context information. The first step in measuring the qualify of context information is to determine users of the context information. This is important because the type of users or applications determines the type of context information and thus the methods of measuring the qualify dimensions and the thresholds for evaluating the quality of context information. The other steps include methods for measuring each quality dimensions to allow quantitative evaluation of quality, establishing acceptable quality targets. We selected accuracy, completeness, up-to-dateness, access security, and representation as quality dimensions and proposed their measurement methods and concrete procedures. We enabled objective evaluation of quality level through proposal of methods suitable to quality measurement of context information.

Various quality models using quality factor, quality criteria and metrics have been proposed in order to evaluate quality of software products. However, a customized quality model which is specific to the characteristics of software component is required. In this paper, we propose external quality prediction techniques enable us to predict what external quality the final software product will have by using metrics as with internal attributes of software in development. We also propose a model not only for measuring quality by using metrics but also for applying internal attributes of ISO 9126 into artifacts of software component development.

The purpose of this study is to identify priority factors for improving service quality of cosmetic stores in drug stores(DRS) and department stores(DES) and to provide basic data for improving service quality of cosmetic stores by analyzing the service quality based on the Kano model and the Potential Customer Satisfaction Improvement (PCSI) Index. As a result, most items of quality factors of cosmetic stores in both stores were evaluated as attractive quality factors. As a result of PCSI Index comparison, the quality factors of 'Reliability', 'Responsiveness', and 'Empathy' items for DRS and 'Empathy' and 'Reliability' items for DES had higher priority for improvement. That is, if these factors are improved, there is a high potential to improve customer satisfaction. Through this study, practical implications were provided by identifying service quality factor classification and priorities for customer satisfaction improvement of DRS and DES. This is expected to contribute to the guidelines for improving customer satisfaction in the future.

Viewpoint about the quality of software is various. But, from the end-user point of view, user interface of software may be all to express the quality of software. But the detailed evaluation criteria were not established about usability evaluation method based on user interface so far, though user interface of software is the main object of usability quality characteristics. In this paper, we established a system about the method extracting and evaluating some quality characteristics elements measurable form user interface of software by analyzing the relationship between the elements constructing quality characteristics and user interface related to quality evaluation of software. We expect that this result of study will be a fundamental study adapting and evaluating to various types of user interface.

The purpose of this paper is to evaluate usability quality through investigating the factors of usability for internet shopping mall websites. For this study, previous studies were investigated and experts' discussions were held. In result, six characters of usability were chosen such as content satisfaction. customer attraction satisfaction, price information satisfaction, public security satisfaction, user interface satisfaction. and process of transaction satisfaction that affect usability of shopping mall websites and the evaluation models of 72 detailed measure factors were established. Since these 72 sub-factors inc)ode the key words of HTML, XML, JSP, and ASP from the target websites. 33 measurable sub-factors in the information were measured through usability evaluation experiment. In addition, a questionnaire about usability measure factors was executed after preferable websites and not preferable websites are selected. After that, we verified the reasonability of usability measure model factors comparing the results of the evaluation experiment with the result of the questionnaire. The time it takes to measure the usability of shopping mall websites can be reduced by using this measurement supporting tool. Also, this tool may be used to estimate the usability during the development of a shopping mall website.

Conventional middleware is software providing services between clients and servers efficiently, but it is not applicable to RFID systems because of low consistency due to the absence of context awareness function, and problems in the management of meaning, security system, etc. Accordingly, we need a quality selection process and a quality evaluation method for selecting RFID middleware based on new criteria. This Paper proposed a new selection process based on international standard ISO/IEC 14598, and extracted and selected optimal quality factors through the proposed process. The selected quality factors were mapped to the quality characteristics of standard quality model ISO/IEC 9126, and to quality factors of RFID middleware of SUN, Microsoft, EPCglobal, IBM, etc. The results of these works showed that the quality factors extracted and selected through the proposed process were fair and adequate for evaluating the quality of RFID middleware.
