Background Interactive response technologies are used in clinical trials to provide services such as automated randomization and medication logistics management. The objective of this article is to investigate the usage of telephone (Interactive Voice Response) and web (Interactive Web Response) interfaces of interactive response technologies at clinical investigator sites in clinical trials, to obtain information about the preferences of interactive response technology end users between the telephone and web interfaces, and to explore the relevance of the telephone interface in this setting. Methods The data consist of an online survey conducted in spring 2016 with clinical investigators, study nurses, and pharmacists in 13 countries. Results Ninety-eight percent of survey respondents preferred the web interface over the telephone interface, the most important reason being superior usability. However, the respondents indicated the usability of interactive response technology interfaces is not optimal, and lack of integration and consistency across systems is common. A vast majority of interactive response technology end users at clinical sites prefer to use the web interface over the telephone interface, but most also feel there would need to be a back-up system. Conclusions Based on the results, it would be beneficial to improve the usability of the interactive response technology interfaces, and to increase consistency across systems from the current level. Support to and training of the users, as well as clarifying the responsibilities between sites and the sponsor should also be a focal point. Study sponsors should explore with interactive response technology service providers how removing the telephone interface would impact future studies, and whether there could be a more efficient means to achieve a reliable back-up to the web interface instead of a dedicated telephone interface.

Big data and IoT has its impact on various areas like science, health, engineering, medicine, finance, business, and mainly, the society. Due to the growth in security intelligence, there is a requirement for new techniques which need big data and big data analytics. IoT security does not alone deal with the security of the device, but it also has to care about the web interfaces, cloud services, and other devices that interact with it. There are many techniques used for addressing challenges like privacy of individuals, inference, and aggregation, which makes it possible to re-identify individuals' even though they are removed from a dataset. It is understood that a few security vulnerabilities could lead to insecure web interface. This chapter discusses the challenges in security and how big data can be used for it. It also analyzes the various attacks and threat modeling in detail. Two case studies in two different areas are also discussed.

In this chapter, the author argues that virtual reality (VR) does have a place in e-commerce as a Web 2.0 application. However, VR is not ready to supplant standard e-commerce Web interfaces with a completely immersive VR environment. Rather, VRCommerce must rely on a mixed platform presentation to accommodate diverse levels of usability, technical feasibility, and user trust. The author proposes that e-commerce sites that want to implement VRCommerce offer at least three layers of interaction: a standard Web interface, embedded VR objects in a Web interface, and semi-immersive VR within an existing Web interface. This system is termed the Layered Virtual Reality Commerce System, or LaVRCS. This proposed LaVRCS framework can work in conjunction with Rich Internet Applications, Webtops, and other Web 2.0 applications to offer another avenue of interaction within the e-commerce realm. With adoption and development, LaVRCS will help propel e-commerce into the Web 3.0 realm and beyond.

The use of color is of great significance to the appearance and usability of web interfaces. However, visually impaired people have always been ignored in web interface design in terms of color scheme. Therefore, it is necessary to study their difficulties while browsing web pages and accessing to information. By means of enumerating the color barriers, this paper summarizes the principles of how to use color in the web interface design for visually impaired people. It is expected that the proposed principles would benefit such people who conduct web interface design while being aware of the needs of visually impaired people.

In SOA framework, Portal applications aggregate and render information from multiple sources in easily consumable format to the end users. Web services seem to dominate the integration efforts in SOA. Traditional data-oriented web services require portlet applications to provide specific presentation logic and the communication interface for each web service. This approach is not well suited to dynamic SOA based integration of business processes and content. WSRP 2.0 aim at solving the problem and providing the framework for easy aggregation of presentation services. Is not practical to publish portlets locally if the organisation wishes to publish their portlets as web services to allow their business partners using these services in their portals. UDDI extension for WSRP enables the discovery and access to user facing web services while eliminating the need to design local user facing portlets. Most importantly, the remote portlets can be updated by the web service providers from their own servers.

AbstractHalal Supply Chain Management requires an assurance that the entire process of procurement, distribution, handling, and processing materials, spare parts, livestock, work-in-process, or finished inventory to be well documented and performed fit to the Halal and Toyyib. Blockchain technology is one alternative solution that can improve Halal Supply Chain as it can integrate technology for information exchange during the tracking and tracing process in operating and monitoring performance. This technology could improve trust, transparency, and information disclosure between supply chain participants since it could act as a distributed ledger and entitle all transactions to be completely open, yet confidential, immutable, and secured. This study uses a Blockchain Network with three channels and uses raft consensus algorithm in designing web interfaces and testing their capabilities. From the web interface, there were no failures in the validity test during the invoke test and the query test. In addition, the web interface was also successfully tested to thwart the formation of a block in case of data input errors from the user. The server can also do the process as a provider of information and validator for the web interface. From the results of simulations conducted on the Blockchain Network that was made, Blockchain’s transaction speed is fast and all the transaction is successfully transferred to other peers. Thus, Permissioned Blockchain is useful for Halal Supply Chain not just because it can secure transactions from some of the halal issues, but the transaction speed and rate to transfer data are very effective.

The development of technology and internet has contributed to more people viewing on-screen content and an increase the amount of material that can be read directly from a Web-based platform. The transformation from paper-based materials to digital materials on the Web, more or less has affected the readability of the materials in which information presented on the printed and web-based documents is dissimilar. However, only few studies have been carried out on the presentation of information specifically, the readability of the text in web-based platform. Meanwhile, readability is one of the crucial aspect of Web usability and could affect the success of a website. The speed of reading is regarded as a good measure of readability. Therefore, this study aims to measure the readers reading speed for web interfaces. This study followed a quantitative analysis method that used experiments to collect data and involved university students as the test subjects. A Web-based Reading Speed Test System (RSTS) was developed for data collection and analysis purpose. The findings of this study found that the web interface with the combination of blue font color, yellow background color and Arial font type have the highest reading speed. In contrary, web interface that consists of combination black font color, white background color and Arial font type have the lowest reading speed. In addition, the reading speed of male participants was slightly higher than the female participants. To conclude, the results of this study signify that the interface design had a significant impact on the students reading speed for web pages.
