The developments in mobile technology and the increase in the production of smartphones have led to the growth of the mobile healthcare market. Moreover, the number of mobile healthcare apps is on the rise, and users are benefiting from using healthcare, exercise tracking, and body monitoring apps, as well as they have been searching for health information through mobile health apps. This paper evaluated the usability of a symptom checker application that provides information on diseases, treatment methods, and related hospitals through self-diagnosis of symptoms. Symptom checkers are currently being developed, and are widely used overseas. This paper sought to evaluate the usability of a symptom checker app, and suggested ways to introduce enhancements.

The purpose of this paper is to propose an analytical method for evaluating user satisfaction of Internet websites using the structural equation model(SEM). This paper is intended to identify critical evaluation factors of user satisfaction for websites to determine criteria for evaluating the websites, and use the criteria to develop a SEM model for quantitatively evaluation of each factors' effects of user satisfaction. The SEM model used 2 variables of usability and good-looks for the evaluation factors of websites user satisfaction and each factors have 4 sub evaluation criteria, 3 portal sites were evaluated to construct the SEM model, and 155 subjects participated the website evaluation using the walk-through and face-to-face survey method. Analysis results showed that the SEM model was statistically significant for all the 3 websites evaluated. Both the usability and good-looks two factors also showed significant effects to user satisfaction of websites and have positive correlation. The user satisfaction was more effected by the usability factor than good-looks, and the simplification and harmonization were the most critical sub-factors of the usability and good-looks.

This study considered the most crucial elements in websites as web usability and web accessibility. The web usability signified the empirical satisfaction of ordinary users on websites and how much they used the relevant websites conveniently and accurately, while the web accessibility signified the technical support that could have an easy access to web contents and the principles of cognitive aspects, by considering the users such as those who have been alienated from information. Even if the people were given lots of beneficial information, the websites would be useless if their usability and accessibility were not considered. It would be necessary to reduce the information gap by letting any users (the physically challenged, the elderly, etc.) give an access to every information without any professional abilities and to provide the efficient websites corresponding to the embodiment goal of e-government through rapidity and accuracy of contents and the feedback for systematic structure and people's demand.

본 논문은 SOA기반 시스템에 대해 품질 평가를 하기 위한 품질평가 모델을 제안하고, 이를 이용하여 ISO/IEC 9126을 참조해서 품질 평가 대상이 되는 5개의 품질 속성 즉, 기능성, 신뢰성, 사용성, 효율성, 유지보수성에 대해 품질평가를 하였다. 그 결과는 "기능성", "신뢰성", "사용성", "효율성" 및 "유지보수성"에 대해서 모두 만족하였다. 또한 이들 5개의 품질속성을 종합한 SOA기반 시스템에 대해서도 61.45%로 만족하였다.

This study examines the impact of knowledge processes (KP) on the performance of knowledge management systems (KMS). It posits that task needs and available functionality of technology existing in an organization could influence the usability of KP and the KMS performance. A firm-level structural model was developed based on data collected from corporate KM users. Survey-based research was carried out to test this model. Following questionnaire development, validation, and pretest with a pilot study, data were collected from 886 knowledge management (KM) users including directors, managers, and workers in a South Korea-based company, Korea Asset Management Corporation (KAMCO), to measure the task needs and available functionality of technology to improve the KMS performance. Results show that the matching between the two factors-technology and task-had a significant influence on the usability of KP and the KMS performance, and a better usability of KP has positive impact on the KMS performance. Implications on KM practices and KMS designs are also discussed.

This paper described the developed website usability evaluation system in terms of Kansei engineering using neural network. Developed system simultaneously operates with the MS Internet Explorer by entering the target URL for usability evaluation, and the results are learned using neural network. We firstly derived the Kansei adjectives and website usability factors and they were matched by the correspondence analysis. Then, highly corresponded adjectives were implemented on the system for the Kansei evaluation. Finally, the results showed the appropriate efficiency of developed algorithm and system for the website evaluation. If more subjects were used for the system learning, the efficiency of system could be improved.

This paper is very exploratory and addresses the issue 'Is a general quality model of software possible?'. If possible, how specific can/should it be?' ISO 25000 Series SQuaRE is generally regarded as a general quality model which can be applied to most kinds of software. Usability is one of the 8 characteristics of SQuaRE's Product Quality Model. It is the main issue associated with SQuaRE's Quality in Use Model too. it is the most important concept associated software quality since using is the only ultimate goal of software products. Playability, however, is generally regarded as a special type of usability, which can be applied to game software. This common idea contradicts with the idea that SQuaRE is valid for most kinds, at least many kinds, of software. The empirical evidences of this paper show that SQuaRE is too specific to be a general quality model of software.

Usability study of the CU Medical "i-PAD" AED was conducted to validate the usability of the device, primarily focused on the trained user as well as the utility of the training material. Comparing these results of the trained participants to those obtained by Callejas et al. (2004), who studied video-trained users of two commercially available Philips AEDs (FR2 and HS1) using a male manikin only, the participants in this study were more successful (100% vs. 85.7%-FR2 vs. 88.9%-HS1) and faster to shock (58.5s-i-PADvs. 91s-FR2 vs. 90s- HS1). While the focus of this study was on validating ease of use for trained bystanders, the results of the untrained condition showed that, from a usability perspective, these devices perform as well as any other AEDs already approved and available for purchase for untrained bystander use, as evidenced by the comparison to various published research results

This article describes the process involved in usability testing a agricultural information Web site. In addition to determining the goals and requirements for the agricultural information Web site, a user and task analysis was conducted for defining the its user base and the types of tasks which users might be performing at the site. Usability testing methods with close observation and in-depth interviews provided fresh insights about how users are interacting with the agricultural information Web interface as they approach various information seeking tasks. This study uncovered problems related to unclear terminology, improper interface, location for navigational links, need for context sensitive help, built-in redundancy, and clear and consistent navigation.
