Performance testing of an architecture of low-cost authentication Rural small-scale WISP Using Mikrotik hotspot and Freeradius server installed on Raspberry Pi 3

As the population ages and the number of people with chronic diseases increases, society is changing from the existing diagnostic- and treatment-oriented medical services to preventive- and management-oriented medical services. This paradigm is named Ubiquitous Smart Healthcare. Various multimedia-based healthcare services are becoming especially key to health management in the smart age. In other words, technology, research, and integration of multimedia healthcare services, such as video data, voice data, IoT networks, and the like, are proceeding. Due to well-being trends and lifestyles of the aging society, medical services are rapidly becoming ubiquitous, in which the individual and the medical professional cooperate closely in hospital-centered treatment services to provide health management and promotion, and prevention of diseases. To realize this, various bio-signal measurement techniques based on multimedia are being studied and applied. Therefore, in this paper, we propose a remote voice signal-measurement system that combines two Impulse Radio Ultra Wide Band (IR-UWB) systems to provide a capable IR real-time location service, and we design and implement them. Also, we can reduce the complexity of existing voice signal–measurement algorithms, and we optimize the system by proposing a filter suitable for voice signal–measurement algorithms. As a result, we confirm that the voice signal can be measured by extending the measurement distance (based on wireless communications) by only about 3 m to 10 m. By applying the measurement and analysis method for voice-signal data in the wireless communication system environment, a healthcare service with improved reliability can be applied. In particular, it is possible to provide a multimedia healthcare computing environment in which new diagnostic data can be found and utilized in the field of multimedia-based healthcare service technology.

     

Personalized Healthcare System for Chronic Disease Care in Cloud Environment

The rapid increase in the number of patients with chronic diseases is an important public healthcare issue in many countries, which accelerates many studies on a healthcare system that can, whenever and wherever, extract and process patient data. A patient with a chronic disease conducts self‐management in an out‐of‐hospital environment, particularly in an at‐home environment, so it is important to provide integrated and personalized healthcare services for effective care. To help provide effective care for chronic disease patients, we propose a service flow and a new cloud‐based personalized healthcare system architecture supporting both at‐home and at‐hospital environments. The system considers the different characteristics of at‐hospital and at‐home environments, and it provides various chronic disease care services. A prototype implementation and a predicted cost model are provided to show the effectiveness of the system. The proposed personalized healthcare system can support cost‐effective disease care in an at‐hospital environment and personalized self‐management of chronic disease in an at‐home environment.     

An integrated healthcare system for personalized chronic disease care in home-hospital environments

Facing the increasing demands and challenges in the area of chronic disease care, various studies on the healthcare system which can, whenever and wherever, extract and process patient data have been conducted. Chronic diseases are the long-term diseases and require the processes of the real-time monitoring, multidimensional quantitative analysis, and the classification of patients' diagnostic information. A healthcare system for chronic diseases is characterized as an at-hospital and at-home service according to a targeted environment. Both services basically aim to provide patients with accurate diagnoses of disease by monitoring a variety of physical states with a number of monitoring methods, but there are differences between home and hospital environments, and the different characteristics should be considered in order to provide more accurate diagnoses for patients, especially, patients having chronic diseases. In this paper, we propose a patient status classification method for effectively identifying and classifying chronic diseases and show the validity of the proposed method. Furthermore, we present a new healthcare system architecture that integrates the at-home and at-hospital environment and discuss the applicability of the architecture using practical target services.     

Integrating a mobile health applications for self-management to enhance Telecare system

A dramatic global increase in the pervasiveness of chronic illness has coincided with a reduction in the availability of healthcare resources, coupled with increased costs for care, forcing a fundamental reevaluation of care processes. These trends have driven interest in the use of advanced healthcare information systems and telematics applications to improve care availability while reducing overall costs, but such measures require taking an integrated approach to a range of interrelated social, economic, political and cultural impacts and challenges. Telecare technologies allow hospitals to continuously monitor biomedical indicators, while providing patients with online services such as clinical appointment scheduling, medical consulting, remote alerts, etc. Telecare has the potential to transform the healthcare industry by reducing costs, increasing quality, and enhancing patient satisfaction. The development of a real-time monitoring healthcare service model through the integration of information and communications technologies (ICT) has emerged as a research priority. This study explores the design, value creation, development and evaluation of Telecare systems and mobile health applications for autonomous health management to ensure appropriate home-based health monitoring and treatment while improving care performance. A well-defined methodology is needed to develop artifacts due to increasing disease complexity. This study develops an Android-based self-management application based on design science research methodology. The App assists users in collecting and monitoring indicators to prompt appropriate care services. This study uses individual home self-care as the basic Telecare unit to design a service model integrating six kinds of healthcare services. Usability testing is conducted to reflect five constructs: system usefulness, ease of learning, information quality, interface quality, and overall satisfaction. Experimental results support previous research findings regarding the Chronic Care Model and enhance the effectiveness of mobile-based services. Our work provides a useful reference to researchers and practitioners interested in understanding how hospitals can better facilitate more effective mobile-based technology adoption in today’s e-health environment.     

A study of Context-Based Adaptive Service Model in home environments

This paper suggests an adaptive service model designed for a context based home environment. This model is based on a ubiquitous home environment that consists of numerous sensors, devices, measuring equipment and common interfaces provided for interoperability. Furthermore, this model provides context information requested under applied services. In order to deal with these service requirements, this paper suggests a software structure based on the distributed object group framework for context based adaptive services in ubiquitous home environments. This context information is modeled under an ontology categorized as distinguishable characters of a home environment. Finally, we show the structure of the system with application services based on it.

Feasibility and performance evaluation of a 6LoWPAN‐enabled platform for ubiquitous healthcare monitoring

Technology has revolutionized medical practices by enabling more convenient and non‐intrusive monitoring of patient's health, leading to next generation ubiquitous healthcare (u‐healthcare). The exploitation of the Internet protocol version 6 addressing space along with the miniaturization of electronic devices has fostered providing interoperability and connectivity of wearable sensor devices in wireless body area networks to the Internet of Things. In this paper, we propose to integrate the IPv6 over low power wireless personal area network (6LoWPAN) to the u‐healthcare monitoring system architecture. The main objective is to study the feasibility of the 6LoWPAN‐enabled platform in real‐world scenarios dealing with medical data. The performance evaluation of this platform is carried out initially through simulations using OMNet++ and then supported by an experimental study using sensor motes and a customized micro‐computing unit. Performance metrics such as throughput, end‐to‐end delay, packet error rate, and energy consumption are investigated under acute health conditions, where patient's health information has to be sent continuously and at maximum rate to the care provider. The obtained results show that the proposed 6LoWPAN solution fulfills the main quality of service requirements of u‐healthcare applications. Copyright © 2015 John Wiley & Sons, Ltd.

Context-aware middleware for pervasive elderly homecare

The growing aging population faces a number of challenges, including rising medical cost, inadequate number of medical doctors and healthcare professionals, as well as higher incidence of misdiagnosis. There is an increasing demand for a better healthcare support for the elderly and one promising solution is the development of a context-aware middleware infrastructure for pervasive health/wellness-care. This allows the accurate and timely delivery of health/medical information among the patients, doctors and healthcare workers through a widespread deployment of wireless sensor networks and mobile devices. In this paper, we present our design and implementation of such a Context-Aware Middleware for Pervasive Homecare (CAMPH). The middleware offers several key-enabling system services that consist of P2P-based context query processing, context reasoning for activity recognition and context-aware service management. It can be used to support the development and deployment of various homecare services for the elderly such as patient monitoring, location-based emergency response, anomalous daily activity detection, pervasive access to medical data and social networking. We have developed a prototype of the middleware and demonstrated the concept of providing a continuing-care to an elderly with the collaborative interactions spanning multiple physical spaces: person, home, office and clinic. The results of the prototype show that our middleware approach achieves good efficiency of context query processing and good accuracy of activity recognition.     

Ubiquitous Information Services with JAIN Platform

To provide responsive information services in a ubiquitous computing environment, service software and system development are indispensable. A component-based ubiquitous information system with a JAIN (Java APIs for Integrated Networks) platform to achieve seamless transmissions and reach-everywhere communications was designed in our research. In this development, numerous ubiquitous service modules were identified: location management, roaming, mobile IP and WAP networking. These component-based network modules were constructed using a component composition language with component specification and interface definition, running on top of a distributed service architecture using a JAIN platform to distribute the ubiquitous information services to mobile users. Two applications, Wireless-Application-Protocol (WAP) Mail and Video-on-Demand (VoD) services, show that the JAIN-like platform with the developed networking components effectively fills the gap for application developers between mobile appliances and various kinds of ubiquitous information services.

An Agent-Based Smart Home System and Its Service-Scheduling Mechanism: Design and Implementation

This investigation presents an agent-based smart (ABS) home system that automates home-service operations. The ABS home system comprises three subsystems, namely user interface, home gateway, and home functionality. ABS home users can request services with handheld devices through an ABS user interface, and receive them through an agent cooperation mechanism. This investigation has designed three agents and implemented them in the agent platform: the manager agent schedules the service processes; the service agent manages service requests, and the task agent executes service operations. With home-functionality subsystems including location servers, message centers, and multimedia centers in ABS homes, services are conveniently provided, efficient, and comfortably manipulated. The Universal Plug and Play feature adopts IP network technology to control, manage, and transfer data among functionality devices in ABS homes. The proposed service-scheduling mechanism provides services that are conveniently provided, efficient, and comfortably manipulated. This study presents an implementation of the ABS home system to illustrate the feasibility of the proposed architecture. The study also presents a performance evaluation to demonstrate the effectiveness of the proposed mechanism.

Digital cities of the future: Extending @home assistive technologies for the elderly and the disabled

In the digital city of the future there is the vision of seamless virtual and physical access for every home and between each home and the workplace, as well as critical city infrastructure such as the post office, the bank, hospitals, transportation systems, and other entities. This paper provides an overview of technical and other issues in extending at home (@home) assistive technologies for the elderly and the disabled. The paper starts by giving a vision of what this city is supposed to look like and how a human is to act, navigate and function in it. A framework for extending assistive technologies is proposed that considers individuals belonging to special groups of interest and locations other than their home. Technology has already reached the state of ubiquitous and pervasive sensor devices measuring everything, from temperature to human behavior. Implanting intelligence into and connecting such devices will be of immense use in preventive healthcare, security in industrial installations, greater energy efficiency, and numerous other applications. The paper reviews enabling technologies that exist and focuses on healthcare applications that support a longer and higher quality of life at home for the elderly and the disabled. It discusses intelligent platforms involving agents, context-aware and location-based services, and classification systems that enable advanced monitoring and interpretation of patient status and optimization of the environment to improve medical assessments. The paper concludes with a discussion of some of the challenges that exist in extending @home assistive technologies to @city assistive technologies.

Telemedicine system using computed tomography van of high-speedtelecommunication vehicle

The current medical system provides medical services to patients who visit hospitals. However, medical services can be provided at or close to the home of the patient using fully-equipped mobile telemedicine systems. Such a system can identify diseases at an early stage, improve the patient's quality of life and prognosis through early diagnosis and treatment, and reduce the cost of the medical service. Furthermore, the unit can provide mass screenings of the population, as well as a full medical service to remote areas. The Telecommunications Advanced Organization of Japan and Shinshu University Hospital established a research center for a unique telemedicine project using a mobile system. The mobile unit consists of a van that houses a spiral computed tomography (CT) machine and various telecommunications equipment. The unit allows medical examinations, CT scanning, and online two-way transfer of image data/teleconferencing to a medical center for consultation with various specialists. We have used the system thus far for the early detection of lung cancer through mass screenings over a four-year period in 29 administrative districts. Mass screenings of 19,117 residents resulted in the identification of 75 cases of early lung cancer in patients who were later treated by partial pneumonectomy. We have also used the system to provide medical services and telemedicine support to remote areas, winter-time telemedicine support to an international sports competition, and various medical services to a home-care facility
