A Generic Method for the Reliable Calculation of Large- Scale Fading in an Obstacle-Dense Propagation Environment

The aim of this chapter is to summarize and present recent findings in the field of wireless channel mod- eling that provide a new method for the reliable calculation of the statistical parameters of large-scale variations of the average received signal (shadow fading). This algorithm is theoretically based on a path loss estimation model that incorporates losses due to walls and floors. This has been confirmed to be the most precise mathematical tool for average signal strength prediction for various frequencies of interest and propagation environments. The total path loss is estimated as a sum of two independent attenuation processes: free space loss and losses due to obstacles. This solution allows for a direct and reliable calculation of the deviation of the fluctuations of the average received signal in an obstacle- dense environment

An assessment of technology-based service encounters & network security on the e-health care systems of medical centers in Taiwan

<p>Abstract</p> <p>Background</p> <p>Enhancing service efficiency and quality has always been one of the most important factors to heighten competitiveness in the health care service industry. Thus, how to utilize information technology to reduce work load for staff and expeditiously improve work efficiency and healthcare service quality is presently the top priority for every healthcare institution. In this fast changing modern society, e-health care systems are currently the best possible way to achieve enhanced service efficiency and quality under the restraint of healthcare cost control. The electronic medical record system and the online appointment system are the core features in employing e-health care systems in the technology-based service encounters.</p> <p>Methods</p> <p>This study implemented the Service Encounters Evaluation Model, the European Customer Satisfaction Index, the Attribute Model and the Overall Affect Model for model inference. A total of 700 copies of questionnaires from two authoritative southern Taiwan medical centers providing the electronic medical record system and the online appointment system service were distributed, among which 590 valid copies were retrieved with a response rate of 84.3%. We then used SPSS 11.0 and the Linear Structural Relationship Model (LISREL 8.54) to analyze and evaluate the data.</p> <p>Results</p> <p>The findings are as follows: (1) Technology-based service encounters have a positive impact on service quality, but not patient satisfaction; (2) After experiencing technology-based service encounters, the cognition of the service quality has a positive effect on patient satisfaction; and (3) Network security contributes a positive moderating effect on service quality and patient satisfaction.</p> <p>Conclusion</p> <p>It revealed that the impact of electronic workflow (online appointment system service) on service quality was greater than electronic facilities (electronic medical record systems) in technology-based service encounters. Convenience and credibility are the most important factors of service quality in technology-based service encounters that patients demand. Due to the openness of networks, patients worry that transaction information could be intercepted; also, the credibility of the hospital involved is even a bigger concern, as patients have a strong sense of distrust. Therefore, in the operation of technology-based service encounters, along with providing network security, it is essential to build an atmosphere of psychological trust.</p

Future automation via ubiquitous communications technologies

The telecommunications and Internet technologies have evolved dramatically during the last decade, laying solid foundation for the future generation of the ubiquitous Internet access, omnipresent web technologies and ultimate automated information cyberspace. As a result, current efforts in the research and development in the areas of next generation of Internet and telecommunications technologies promote formation of inter-disciplinary international teams of experts, scientists, researchers and engineers to create a new generation of applications and technologies that will facilitate the fully-automated information cyberspace systems, such as future house 2015. The author discusses the current state of the art in the world of telecommunications and Internet technologies, new technological trends in the Internet and automation industries, as well as the concept of the fully-automated future house 2015, while promoting research and development in the inter-disciplinary projects run by multinational teams world-wide

Methodology to measure the quality of service in healthcare information and telecommunications infrastructures

The telecommunications industry in last decade went through the dramatic changes motivated by mobility, wireless technologies and miniaturization. The continuous increase in the complexity and the heterogeneity of healthcare telecommunications infrastructures requires reliable methodology to assess the quality of service provision. This article presents a cost effective methodology to assess the user's perception of quality of service provision utilizing the existing Staffordshire University network by adding a component of measurement to the existing model presented by Walker. This paper offers a cost effective approach to assess the QoS provision within the University campus network, which could be easily adapted to any campus network or healthcare organization in the world
