PDAs in medical settings: the importance of organization in PDA text design

This article reports on the utility of personal digital assistants (PDAs) for processing information needed in coordinated, team-based medical work. The author first presents results from a survey of medical professionals, which reveal that medical professionals read PDA-based texts nonlinearly, in short bursts, and without need of a narrative-based organization. The respondents also reported using PDAs to support a range of team-based activities. The author then presents results of a case study of veterinary students using PDAs on clinical rotations. He discusses how the PDA affords uses of text-based information that are suited to medical work that is carried out with the cooperative assistance of people and technologies. After discussing how veterinary students used PDAs to organize information into ad hoc texts, he concludes with challenges and information design guidelines for professional writers in the medical field.

Object-oriented modeling of patients in a medical federation

Explores the development of an object-oriented model to support the inter-operation of simulations within a federation for the purpose of conducting medical analysis and training over a distributed infrastructure. The medical federation is referred to as the Combat Trauma Patient Simulation System and is composed using a high-level architecture. The infrastructure contains components that were separately developed and are heterogeneous in nature. This includes a general anatomical database that is capable of analyzing human injuries, referred to as operational requirements-based casualty assessment, an animated mannequin called the Human Patient Simulator, and other components. The research develops an object model that enables bodily injury data to be shared across the simulation, conducts analysis on that data and considers possible applications of the technique in expanded medical infrastructures     

Fuzzy Near Compactness Based Personalized Recommendation for Preventing Patients with Type 2 Diabetes Mellitus and Hypertension from Cardiovascular Complication

Undeniably, preventing cardiovascular complication for patients with type 2 diabetes mellitus and hypertension is a challenge in the healthcare area. However, the prevention of these patients from a cardiovascular complication does not obtain much attention despite the rate of morbidity and mortality with cardiovascular complication increasing every year. To prevent each individual patient from not getting worse in health status, personalized recommendation is revealed as the most effective motivation in self-healthcare management with optimal process. Consequently, this paper proposes a personalized recommendation using the intelligent supporting system to prevent the patients with type 2 diabetes mellitus and hypertension from a cardiovascular complication, whereas the appropriated activities of daily living will be recommended as a suitable lifestyle. This recommendation system is modeled with fuzzy near compactness to measure the similarity between the patient’s conditions and practice plans in order to retrieve the most optimal practice programme which is obtained as a personalized plan for each patient. To conduct this model, this paper acquired the clinical data, lifestyle data, and trends of health status data from the patient history. The recommendation by this proposed model was suggested from the fuzzy near compactness algorithm which was constructed from the knowledge and experience of ten medical experts. The experimental results, on 744 datasets based on the total of checking up of 162 patients, show that the proposed recommendation model can achieve 96.63% accuracy when compared with the diagnostic results made by other five medical experts.

     

Horton and Wohl Revisited: Exploring Viewers' Experience of Parasocial Interaction

Linking back to D. Horton and R. Wohl (1956) , the present approach conceptualizes and empirically examines viewers' parasocial interaction experience with a TV performer. Causes and outcomes of parasocial interaction experience are examined. To this end, a new Experience of Parasocial Interaction (EPSI) scale is introduced. In a 2 (Bodily Addressing) × 2 (Verbal Addressing) between‐subjects experiment (N = 198) viewers reported a more intense parasocial experience if they were addressed by a TV performer on a bodily and verbal level. In addition, the more viewers perceived the performer to be attractive and the stronger their perspective‐taking ability, the more intense their parasocial experience. Stronger parasocial experience resulted in higher commitment to social norms and a greater enjoyment of the exposure situation.     

Reconceptualizing Address in Television Programming: The Effect of Address and Affective Empathy on Viewer Experience of Parasocial Interaction

Much scholarship has examined the parasocial bonds between audiences and media personalities. However, recent research differentiated between the development of parasocial relationships and the actual experience of parasocial interaction (EPSI) that can result from structural elements of a message such as style of address (Hartmann & Goldhoorn, 2011). This study presents an alternate conceptualization of style of address and employs an online assessment to examine its impact on the EPSI. Results indicated that bodily address, where the onscreen performer could be seen speaking to the viewer, fostered a stronger sense of interaction relative to verbal or no address. Moreover, emotional contagion, an affective component of empathy, likewise facilitated these perceived interactions, most strongly in response to bodily address.     

Behind the growth of FinTech in South Korea: Digital divide in the use of digital financial services

Advancements in financial technology, known as “FinTech,” will help both businesses and consumers of financial services. South Korea has a well-established FinTech infrastructure and resources, and has already incorporated digital financial services into daily life. However, the benefit of the proliferation of FinTech might be disproportionate in reaching diverse groups. The goal of this study is to examine how digital financial services are used in South Korea with an emphasis on disparities in the use of digital financial services. This study used the 2019 Digital Divide Survey conducted in South Korea to conduct OLS regression analysis, and create the Concentration Index (CI), which estimates the disparities that are systematically related to income level. Next, decomposition analysis on the CI was conducted to determine what factors help explain the disparity in the use of digital financial services. The analysis confirmed that there are considerable differences in the usage by income level. The multivariate results reveal that one’s device proficiency and active involvement in utilizing the internet for basic activities played significant roles in explaining the level of digital financial services usage. Poorer individuals' attitudes toward new technologies, such as a lack of interest in participating in learning and confidence in obtaining new digital skills, may prevent them from using digital financial services. This study is one of few studies to use the CI technique to examine the digital divide in digital financial services, and provide insights for educators, businesses, and policymakers.

Development of emulator for walk-through metal detectors

Because of anecdotal reports that magnetic fields from walk-through metal detectors may interfere with the operation of personal medical devices, interest has grown in the development of emulators that can simulate the magnetic fields produced by these metal detectors. This paper describes a system that can produce linearly polarized magnetic fields that have temporal characteristics such as those generated by some walk-through metal detectors. Because the electronic components are "off-the-shelf" devices and the coil can be readily fabricated, the system could be used by manufacturers of medical devices to conduct their own electromagnetic interference tests     

Bioethics & the brain

Microelectronics and medical imaging are bringing us closer to a world where mind reading is possible and blindness banished - but we may not want to live there. New ways of imaging the human brain and new developments in microelectronics are providing unprecedented capabilities for monitoring the brain in real time and even for controlling brain function. The technologies are novel, but some of the questions that they will raise are not. Electrical activity in the brain can reveal the contents of a person's memory. New imaging techniques might allow physician to detect devastating diseases long before those diseases become clinically apparent. And researchers may one day find brain activity that correlates with behavior patterns such as tendencies toward alcoholism, aggression, pedophilia, or racism. But how reliable will the information be, how should it be used, and what will it do to our notion of privacy? Meanwhile, microelectronics is making access to the brain a two-way street. The same electrical stimulation technologies that allow some deaf people to hear could be fashioned to control behavior as well. What are the appropriate limits to the use of this technology? Ethicists are only now beginning to take note of these developments in neuroscience.

Neue epidural arbeitende Gehirndrucksonde — Labortests und Tierversuche — Stand der Entwicklung

The controlling of the intracranial pressure (ICP) is of significant importance for the treatment of patients suffering from cerebral trauma. There are two ways used in the clinical practice to measure the ICP, the intraventricular (inside the dura) and the epidural measurement (between the dura and the cranial-bone). From the viewpoint of accuracy of measurement the intraventricular measurement is to be preferred. However, from the medical point of view this method also involves bacteriological danger. For that reason the improvement of the epidural devices, based on an analysis of the at the time being used measurement devices, is described in detail in this paper.     

Reliability considerations for the BioMEMS designer

The emerging field of biomedical microelectromechanical systems (bioMEMS) has the potential to revolutionize how drugs are discovered, how diseases are diagnosed, and how treatments are administered. Nevertheless, that potential is unlikely to translate into commercial success unless bioMEMS designers can prove that such novel functionality can be delivered each and every time without failure. The life-and-death ramifications of a system failure make absolute reliability a moral and regulatory requirement for many medical applications. This paper reveals the reliability hurdles that must be overcome when systems are used for pharmaceutical research, clinical diagnostics, or implantation into humans. Special attention is given to challenges that are likely to be exacerbated for miniaturized devices. Techniques useful for characterizing, minimizing, and monitoring for failures are also described. A strategy for addressing reliability problems is also presented. By refining bioMEMS for the research laboratory first and then applying the experience gained from that environment to clinical diagnostics applications, bioMEMS does not need to confront head-on the regulatory hurdles and established technologies that could otherwise impede its entry. Similarly, development of more robust, miniaturized clinical diagnostics systems can simplify the entry of implanted bioMEMS.     

Automated topographic segmentation and transit time estimation in endoscopic capsule exams

Endoscopic capsule is a recent medical technology with important clinical benefits but suffering from a practical handicap: long exam annotation times. This paper proposes and compares two approaches (Bayesian and support vector machines) that can be used to segment the gastrointestinal tract into its four major topographic areas, allowing the automatic estimation of the clinically relevant gastric and intestinal sections and corresponding transit times. According to medical specialists, this can reduce exam annotation times by up to 12% (15 min). This automatic tool has been integrated into our CapView annotation software that is currently being used by three medical institutions.     

A Cluster-Based MAC Protocol for Cognitive Radio Ad Hoc Networks

The cognitive radio (CR) technology is an efficient approach to share the spectrum. But how to access the idle channels effectively is a challenging problem. To solve this problem, we propose a MAC protocol for cluster-based CR ad hoc networks, with the aim of making cluster structure more robust to the primary users’ channel re-occupancy activities, so that the CR users can use the idle spectrum more efficiently. Under this framework, a cluster formation algorithm based on available channels, geographical position and experienced statistics is proposed to maximize the network throughput and maintain the cluster topology stability. The schemes for new CR user joining a cluster and cluster maintenance are also designed. An experience database is proposed to store the experienced statistics which are obtained from spectrum occupancy history. Such a database can be used to support the acts of nodes, such as neighbor discovery and cluster forming. Simulation results reveal that our proposed framework not only outperforms conventional CR MAC protocols in terms of throughput and packet delay, but also generates a smaller number of clusters and has more stable cluster structure with less reclustering time.

The Semiconductor Research Corporation: Cooperative research

The SRC (Semiconductor Research Corporation) was formed in 1982 to conduct generic, cooperative university research in the field of integrated circuits. An overview is provided of the methodologies used by the SRC for the identification of pacing integrated-circuit technologies, for research program planning and management, and for the transfer of research results to members. Several case studies are developed that illustrate the SRC approach to the conduct of research and that give a perspective on the broad spectrum of research results being produced. The SRC has found that the process of defining generic research goals, followed by the development and implementation of research plans to achieve the stated goals, provides effective focus and metrics for measuring research progress. It is the SRC's experience that focused university research can provide substantial contributions to the advancement of semiconductor technology as well as an additional work force to enhance the industry, university, and government technical infrastructure of the United States
