Quick Abstract

Access Control to patients’ medical information in Hospital Information Systems (HIS) is a challenge in modern Patient-Centered (PC) healthcare. Fine–Grained Access Control (FGAC) in particular has been identified as one of the security requirements in these systems. In FGAC, only parts of medical information that are relevant and required by healthcare providers are accessed at the point of care. This cannot be achieved without a holistic view of a medical condition through a Patient-Centered Fine-Grained Access Control (PCFGAC), in which patient-centricity is considered. This research proposes using Business Process Management (BPM) to achieve PCFGAC in order to provide a real-time access control based on a “need-to-know” principle. Through a prototype that uses BPM, security requirements of PCFGAC were met. These include: authority control, informed decision support, fine-grained access control, and dynamic policies support. Thus, a contribution to the knowledge and practice has been introduced.

Topic: Health and Fitness

Author: Mohammad Ali Alahmadi

Affiliation: College of Sport Science and Physical Activity and King Saud University, Saudi Arabia

Digital Object Identifier: 10.5220/0005611401450149

Proceedings of icSPORTS 2015, ISBN: 978-989-758-159-5

Quick Abstract

The main aim of this study was to design an electronic device to objectively monitor Television (TV) viewing time in children. The second aim was to examine the relationship between TV viewing time and physical activate activity (PA). Seven children (mean ± SD, age, 10.7 ± 2.1 years; body mass, 35.7 ± 17 kg; height, 137.4 ± 12.3 cm) participated in this study. TV viewing time was directly measured for two consecutive days by a novel wireless electronic device, using Radio-frequency identification (RFID) technology which was connected to a main electronic board that is designed to measure TV viewing time in minutes. PA was also measured, concurrently with TV viewing time measurement, by pedometers (Yamax Digiwalker SW-700) for 3 consecutive days. The preliminary results show that the average TV viewing time of children was 248 ± 188 min/day. Participants also recorded a mean of 10731 ± 3399 steps per day. The average TV viewing time was positively associated with the average steps in children, but not statistically significant (r= 0.74, p= 0.056). It is concluded that the current study produces a novel wireless electronic tool that can monitor TV viewing time in children. It is also concluded that high association between TV viewing time and PA was observed among children, although not statistically significant.

Quick Abstract

We develop an Automotive Reaction System (ARS) framework to support cars by capabilities to react to various situations. With ARS, the states and actions of a car are designed as objects of a high level objectoriented language, called ARS-language. ARS permits also to design the reactions of a car to various situations by an ARS-specification consisting of rules “condition->action”. The ARS-objects and ARSspecification are implemented in a car to provide her with capabilities to function and react online. ARS permits also to model certain actions of a car at a high abstraction level by an ARS-model consisting of rules “condition->operation”. With ARS, we are confronted to conflicts (or feature interactions) which denote situations where an ARS-specification implies simultaneous executions of incompatible actions. We propose an approach to detect and resolve feature interactions.

Proceedings of NCTA 2014/IJCCI, ISBN: 978-989-758-054-3

Quick Abstract

Mobile Ad hoc Networks (MANET) are self-organized networks which are characterized by dynamic topologies in time and space. This creates an instable environment, where classical routing approaches cannot achieve high performance. Thus, adaptive routing is necessary to handle the random changing network topology. This research uses Reinforcement Learning approach with Q-Routing to introduce our MANET routing algorithm: Stability-Aware Cognitive Packet Network (CPN). This new algorithm extends the work on CPN to adapt it to the MANET environment with focus on path stability metric. CPN is a distributed adaptive routing protocol that uses three types of packets: Smart Packets for route discovery, Data Packets for carrying data payload, and Acknowledgments to bring back feedback information for the Reinforcement Learning reward function. The research defines a reward function as a combination of high stability and low delay path criteria to discover long-lived routes without disrupting the overall delay. The algorithm uses Acknowledgment-based Q-routing to make routing decisions which adapt on line to network changes allowing nodes to learn efficient routing policies.

Using a Hopfield Iterative Neural Network to Explain Diffusion in the Brain’s Extracellular Space Structure

Topics: Industrial, Financial and Medical Applications; Computational Neuroscience

Author: Abir Alharbi

Affiliation: King Saud University, Saudi Arabia

Digital Object Identifier: 10.5220/0005029300970104

Proceedings of NCTA 2014/IJCCI, ISBN: 978-989-758-054-3

Quick Abstract

Many therapies for drug delivery to the brain are based on diffusion, and diffusion in this extracellular space is based on micro-techniques that can be modelled with classical differential equations such as the point source diffusion equation. In this paper an energy function is constructed using a finite-difference approximation to the governing diffusion equation and then minimized by a Hopfield neural network. The synergy of Hopfield neural networks with finite difference approximation is promising. The neural network approach is capable of giving insight to the complex brain activity better than any other classical numerical method and the parallelism nature of the Hopfield neural networks approach is easier to implement on fast parallel computers and this will make them faster than the traditional methods for modelling this complex problem. Moreover, the effect of the involved parameters on the diffusion distribution and drug delivery in the ECS is investigated.

Electronic Monitor for Monitoring TV Viewing Time - Description and Significance

Topic: Applied Physiology and Exercise

Author: Mohammad Ali Alahmadi

Affiliation: King Saud University, Saudi Arabia

Digital Object Identifier: 10.5220/0004636600910094

Proceedings of icSPORTS 2013, ISBN: 978-989-8565-79-2

Quick Abstract

Sedentary behaviour is related to adverse cardiometabolic risk profiles and premature mortality. Television (TV) viewing time is the most predominant sedentary behaviour. There are also adverse associations between TV viewing time and a number of cardiovascular risk factors such as the metabolic syndrome, obesity, and abnormal glucose metabolism. Few measurement tools, such as direct observation and videotaping, have been utilized to objectively monitor TV watching. Unfortunately, these measurements have shortcomings as they invade the personal privacy and are impractical in large-scale research studies. Therefore, there is a need for alternative objective measures. Therefore, the main aim of this paper is to design an electronic device to objectively monitor TV viewing. This device uses Radio-frequency identification (RFID) technology that transfers data using tracking tag that is attached to a child's wrist like a watch. This data will be collected by the RFID Reader which is connected to a main electronic board that is designed to measure TV viewing time in minutes. The current research is expected to produce a novel wireless electronic tool that can monitor TV viewing without intrusion to the person privacy and can be widely used as an objective method of assessing TV viewing time.

Proceedings of BMSD 2013, ISBN: 978-989-8565-56-3

Quick Abstract

This paper describes a case study of Enterprise Resource Planning (ERP) implementation in a public-private partnership organisation. The primary focus of the study is to explore, from a holistic view, how Return On Investment (ROI) can be achieved through effective management of roles and responsibilities in an ERP implementation context. The paper starts with an introduction, which includes highlights from the literature indicating the significance of roles and responsibilities management among various ERP stakeholders. The introduction is followed by a brief description of the research methodology used, and then followed by a description of the chosen case study for this paper. The case is then analysed with more focus on how roles and responsibilities among ERP stakeholders interrelate with the implementation outcomes. A separate section is dedicated to extracting appropriate lessons that improve ROI from ERP investment. The findings from the case are assessed through the literature and a published case study that is addressed to ERP stakeholders. The result of discussing the case findings will be presented in a new version of the management framework for the stakeholder’s roles and responsibilities in the context of ERP.

Proceedings of Doctoral Consortium 2013/IJCCI, ISBN: Not Available

Quick Abstract

The research introduces a new Stability-Aware Cognitive Packet Routing Algorithm to provide Quality Of Service (QoS) to packets in Mobile Ad hoc networks (MANET) through long-lived, short delay routes. It extends the work on Ad-hoc Cognitive Packet Network (AHCPN) to adapt it to the MANET environment. It uses Smart Packets (SP) to find and maintain paths that provide specific QoS goals to each packet. Smart Packets move through the network collecting information to be able to make decisions by “learning” from the experience of previous SP’s of the same QoS goals. The routing algorithm constructs Random Neural Networks (RNN) at each node with a neuron for each output link in order to make a routing decision. The algorithm uses Computational Intelligence to make routing decisions with high probability to stable nodes in th e network. A feedback system is subsequently used based on Reinforcement Learning through Acknowledgments to update network information in RNN’s. The proposed algorithm defines a combined routing goal function that considers both the associativity of the node for stability and path delay to result in short, long-lived paths. The degree of associativity of a node is determined via low frequency periodic beacons to identify itself to its neighbors.

Proceedings of IDEE 2012/ICEIS, ISBN: 978-989-8565-17-4

Quick Abstract

The aim of this paper is to detail the creation process of a screening program for Learning Difficulties (LDs), with the goal of alleviating distractions in the interface while retaining essential elements for measuring cognitive abilities and behavioral responses. The program is designed to screen general populations of children ages between 4 and 9 years –with and without Learning Difficulties- and measures five cognitive abilities. Design considerations for accessibility and usability in each component are described. Particular emphasis in the design of this screening system is given to the cognitive effort involved in interacting with the forms, which are affected by the interface's complexity and the navigation structure (i.e. breadth and depth of the information architecture). The assumption was that focusing on designing interfaces that are intuitive and accessible for individuals with LDs would facilitate access to a wider population of children who do not have any LDs or have limited proficiency in interacting with computers because the program was intended for launching across the geographical region of Saudi Arabia, in metropolitan cities as well as rural areas.
