The purpose of this study was to determine the current usage of mobile devices, preferences of mobile learning environments and examine the readiness of nursing students in a public university. In order to investigate preferences and attitudes with respect to mobile technology use in nursing education, 387 students at a state university have been surveyed. It has been observed that while students preferred their current portable laptops, those in higher classes were more inclined to favor mobile phones. The common problems of battery life and high cost of communication, both in smartphones and tablet systems, suggest that hardware quality and financial constraints seem to be two main factors in determining these technologies. While more than half of students expressed readiness for mobile learning, one quarter indicated indecision. Through multivariate regression analysis, readiness to use mobile learning can be described in terms of perceived ease of use, perceived usefulness, personal innovativeness, self-management of learning, perceived device limitation, and availability. Class level, perceived ease of use, personal innovativeness, and self-management of learning explain intention to use mobile learning. Findings obtained from these results can provide guidance in the development and application of mobile learning systems.
'Personal Nutrition Management Tool' (PENUMAT) is an interactive web-based application which aims to help individuals seeking nutrition information on the Internet. However, little is known about the usability of such applications. The purpose of this study was to evaluate the usability of PENUMAT using multi-method approach. For an in-depth usability analysis, using a multi-method approach involving protocol analysis, interviews and a system usability scale (SUS) was adopted. The sample consisted of 10 healthy (five males and five females) volunteers between the ages of 22 and 60. The overall usability score was calculated; usability problems and users' opinions were obtained. All usability problems were classified according to the heuristics and listed with their frequencies. Overall, the usability score ranged from 77.5 to 100, with a median of 88.7. In-depth usability analysis exposed several usability problems mostly related to content, navigation and interactivity. Interview results showed that 'being personal and private' (70%) and 'providing personal feedbacks' (60%) were the most appreciated characteristics of the tool. Although the tool has an acceptable overall usability score, several unnoticed usability problems of the interface design were realised with the in-depth analysis. Therefore, the importance of using a multi-method analysis of usability was pointed out.
Abstract:Hospital information system (HIS) evaluation frameworks have largely been discussed in the literature. framework is not a rival of but is rather an alternative or complementary to the existing frameworks. It is a different approach and has a different computation methodology, supported by fuzzy logic. The acceptable meeting ratio depends on the evaluator; we do not propose a threshold.

The aim of this study is to develop and evaluate a web-based clinical decision support system (CDSS) containing clinical guidelines and protocols that will support intensive care unit (ICU) providers in making decisions more effectively and quickly. First, a survey was carried out with 38 physicians in order to determine their preferences, needs and concerns regarding decision support tools. After the survey, guidelines were prepared by a group of specialists in ICU, and a medical informatician converted the guidelines into algorithm forms. Ten CDSS were developed using the algorithms, and placed onto the Intensive Care Decision Support Website (ICDSW). In order to evaluation of the website, 15 physicians were asked to answer 10 questions in 10 different scenarios first using a paper-based approach, then with ICDSW. When the answers were analyzed, it was found that the answers given by using ICDSW were significantly better than the paper-based approach (p < 0.001). However, there was no significant difference in terms of the time needed to answer the questions (p = 0.138). The usability score of the website was 85.6 ± 8.89. The study demonstrated the successful implementation of an ICDSW within intensive care units.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
